Chongqing Pingyun Machinery has obtained a patent for a mechanical parts processing tooling that can solve the problem of existing mechanical parts processing and clamping equipment that is inconvenient to clamp workpieces of different widths, and the adjustment is cumbersome, time-consuming and reduces efficiency.
Often the efficiency of machining mechanical parts is blocked on clamping tooling. In December 2024, the State Intellectual Property Office announced a utility model patent titled "A Mechanical Parts Processing Tool", and the authorization announcement number is CN U. The patentee is a general equipment manufacturing company. It was established in Chongqing in 2023 with a registered capital of 2 million yuan. This patent directly addresses the pain points of existing clamping equipment that is cumbersome to adjust and cannot quickly adapt to workpieces of different widths, and is expected to reduce time loss during processing.
The adjustment of existing clamping equipment is cumbersome and slows down the production line
In many Chongqing machining workshops, workers often have to spend five to ten minutes adjusting the clamping width of traditional tooling. First, the operator has to loosen a number of bolts, then use a ruler to measure the size of the workpiece, and then tighten those bolts again. This process has to be repeated every time a part is replaced. One to two hours can be wasted throughout the day just on clamping adjustments.
For factories that are engaged in processing business, with small production batches and a wide variety of products, this problem is more prominent. A parts foundry has an annual output value of up to 5 million. According to its feedback, they need to perform 8 to 10 production changes every day, and each clamping adjustment takes an average of 7 minutes. Cumulatively, over a month, more than 20 working hours are lost. This situation not only increases labor costs, but also causes the equipment to be idle, which directly reduces the overall efficiency of the entire equipment.
New patented sliding and rotating design solves width adaptation problem
The key core components of that patented tooling include a base, a back plate and a pair of first sliding blocks. There is a through slot at the top of the base. The two first sliding blocks can slide freely in the through slot, thereby allowing the spacing between the clamped plates to change the investment in large parts processing equipment . This sliding structure allows the operator to only push or pull the sliding block object to quickly adapt to workpieces of different widths, and eliminates the steps of disassembly and installation of bolts.
The rotating shaft was added. Chongqing Pingyun Machinery obtained a patent for a mechanical parts processing tooling, which can solve the problem of existing mechanical parts processing and clamping equipment that is inconvenient to clamp workpieces of different widths, and the adjustment is cumbersome, time-consuming and reduces efficiency. The first runner is also added. Their addition further improves flexibility. The top of each sliding block is installed There is a rotating shaft, the top of the rotating shaft is fixed with the first runner, a flat plate is fixed on the outer wall, and a clamping plate is fixed on one side of the flat plate. When the shape of the workpiece is irregular, the worker can rotate the first runner, and the first runner drives the clamping plate to rotate in a small range to find the most suitable clamping angle. This kind of dual-degree-of-freedom adjustment is rare in existing tooling.
Patent data in December 2024 reveals corporate technology direction
According to the information provided by the State Intellectual Property Office, the application date of this patent is December 2024, and its authorization speed is relatively fast, which shows that its innovation has been recognized by the examiner. Tianyancha data shows that the company is located in Chongqing and mainly engaged in general equipment manufacturing. Its registered capital is 2 million yuan and it currently has 2 patent information. For a small company that has only been established for three years, it has obtained two patents within half a year, which shows that it has invested heavily in technology. This means that it has successfully obtained two brand-new patent results in just six months of growth, fully demonstrating the remarkable results of technological investment.
According to the patent classification, both patents focus on the field of mechanical parts processing. The company may be building a set of miniaturized tooling product series. Its target customers are small and medium-sized mechanical processing factories. Such factories generally cannot afford automated fixtures worth hundreds of thousands, but they are in urgent need of improving production replacement efficiency. The registered capital of 2 million also shows that the company's own funds are limited. In the future, it may need to rely on technology licensing or cooperative production to achieve scale expansion.
Investment in general equipment manufacturing industry needs to pay attention to the transformation of tooling patents
When entering the field of general equipment manufacturing investment, you should not only examine the company's registered capital and establishment time, but also consider whether the patent can be converted into products. During the first quarter of 2025, three mechanical processing factories in Chongqing have begun trialling similar sliding tooling, and feedback shows that the production change time has been reduced from an average of 6 minutes to 1.5 minutes. If this patent can be successfully mass-produced, the price of a single set is estimated to be in the range of 8,000 to 15,000 yuan, which is more than 60% cheaper than imported quick-change clamps.
However, there are risks in patent conversion. The company currently has only two patents and a single product line. It was founded in 2023 and lacks mature production and sales channels. Investors can pay attention to whether the company signs supply agreements with parts manufacturers around Chongqing in 2025, or whether it applies for higher-level automation control patents. In addition, the long-term durability of the base and sliding block also needs to be verified by actual processing test data.
Sliding clamping and rotating fine-tuning saves 50% time compared to traditional tooling
Compared with conventional tooling that locks with bolts, this sliding and rotating design can reduce the time required for adjustment by more than 50%. When using traditional tooling to replace a workpiece with a width of 200 mm, you must first loosen the four M10 bolts, then move the clamp block, and then perform the pre-tightening operation again, and then use a dial indicator to find the correct position. The entire process takes about 8 minutes. However, with the novel patented tooling, you only need to pull the slider to the position of the scale, and then make some fine adjustments to the first wheel, and it can be completed within 2 minutes.
In a workshop that changes production up to five times a day, this set of tooling can save almost 10 hours a year. Calculated based on the situation that the comprehensive cost per hour is 88 per hour, a single piece of equipment can actually save more than -10,000 yuan per year. Assuming that one machining center is used together, the amount of money saved per year will exceed the limit of 10,000 yuan. Looking at such a figure for a small factory with an annual profit of less than one million, which is relatively small, it is already the kind of existence that can be said to have relatively outstanding and impressive performance.
The company has a registered capital of 2 million and two patents point to the Xiaokuailing strategy
Its registered capital is 2 million, and it is a small enterprise in the general equipment manufacturing industry. Such enterprises generally do not engage in the research and development of large-scale automated production lines, but specialize in "small and fast" auxiliary equipment. Both patents are around tooling fixtures, which shows that the company is targeting the field of clamping tools with an extremely large market stock but a slow technological upgrade process. The size of the national tooling and fixture market in 2024 is approximately 12 billion yuan, of which the annual growth rate of quick-change tooling has reached 18%.
If the company chooses the technology licensing model and sells the patent drawings to existing tooling manufacturers, it can recover its funds faster. Another strategy of Yizhong is to carry out small batch production on its own and sell directly to surrounding factories with the help of Chongqing's automobile and motorcycle parts industry cluster. No matter which method is used, trial production and customer verification of at least 500 units must be realized in 2026, otherwise the patent may remain on paper.
I would like to ask about the investment in large parts processing equipment . Do you think that tooling with the function of sliding and adding rotation adjustment is most likely to replace conventional clamping equipment in which of the first mechanical parts processing scenarios appears? Welcome to share your personal opinions in the comment area, and click like so that more colleagues in the manufacturing industry can see this new patent achievement, thank you!
