In the process of machine tool processing, through precise cutting, grinding, drilling and other operations, raw materials are accurately processed into parts with specific shapes, sizes and performances.

[0003] In the process of parts processing, especially the processing of iron ring products, it is often necessary to use a clamping mechanism to fix the workpiece to ensure the stability and accuracy of the processing process. However, when clamping iron ring products, traditional clamping mechanisms often have problems such as inaccurate centering and uneven clamping force, which not only affects the processing quality, but also may cause damage to the machine tool and scrapping of the workpiece.

[0004] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop an automatic centering and balancing jaw mechanism for machine tool processing. Utility Model Content

[0012] As a preferred technical solution, an iron ring is arranged between the plurality of copper clamps, and the outer wall of the iron ring abuts against the copper clamp, and the top surface abuts against the pre-pressing ejector pin.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The utility model is an automatic centering and balancing clamping mechanism for machine tool processing, which is provided with a copper clamping jaw, and a plurality of transverse grooves are provided on the inner wall, which is installed at the output end of the clamping jaw cylinder through a clamping seat. When the clamping jaw cylinder is actuated, the copper clamping jaw can be driven to clamp the iron ring.

The positioning triangle block is connected to the jaw cylinder through the positioning hole, so that the balancing buffer assembly can be stably installed on the jaw cylinder. The coordinated use of the adjusting clamp ring, pre-stressing sleeve, pre-stressing ejector pin and pressure spring can adjust the clamping force according to actual needs to meet the processing requirements of different iron ring products. By adjusting the pressure adjustment nut, the compression amount of the pressure spring can be changed, thereby achieving precise adjustment of the clamping force. The utility model has a simple structure and is easy to operate. Through the coordinated use of the copper jaws and the balancing buffer assembly, automatic centering and balancing clamping of the iron ring products is achieved, the processing accuracy and stability are improved, the scrap rate and production cost are reduced, and it has broad application prospects.

A balancing buffer assembly is arranged between the multiple groups of clamp seats 11, and the balancing buffer assembly includes a positioning triangle block 31, a positioning hole 311 is arranged at the center of the positioning triangle block 31, and the positioning hole 311 is connected to the jaw cylinder 1 by bolts, an adjustment clamp ring 33 is arranged at the bottom of the positioning triangle block 31, a guide slide 32 is arranged on the back of the adjustment clamp ring 33, the guide slide 32 is slidably connected to the positioning triangle block 31, and is locked and fixed by bolts, a pre-stressing sleeve 35 is arranged in the adjustment clamp ring 33, and the pre-stressing sleeve 35 is movably connected A pre-stressing ejector pin 37 is slidably connected to the pre-stressing sleeve 35, and a step block is provided at the tail of the pre-stressing ejector pin 37 for sliding limit. A pressure spring 36 is provided between the pre-stressing ejector pin 37 and the pre-stressing sleeve 35. An inner thread is provided on the inner wall of the pre-stressing sleeve 35, and a pressure adjusting nut 34 is installed on the inner thread. The pressure adjusting nut 34 abuts against the pressure spring 36. An iron ring 2 is provided between the multiple copper jaws 12, and the outer wall of the iron ring 2 abuts against the copper jaws 12, and the top surface abuts against the pre-stressing ejector pin 37.

[0022] The working principle and use process of the utility model: when in use, first, according to the size and processing requirements of the iron ring 2 to be processed, the position of the clamping ring 33 and the pre-pressing sleeve 35 is adjusted, and the compression amount of the pressure spring 36 is changed by adjusting the pressure adjustment nut 34, so as to achieve accurate adjustment of the clamping force. In this way, it can be ensured that the copper clamping jaw 12 has a suitable clamping force when clamping the iron ring 2, avoiding problems caused by being too tight or too loose.

[0023] Start the clamping jaw cylinder 1 to drive the multiple clamping seats 11 and the copper clamping jaws 12 to approach the iron ring 2. After the copper clamping jaws 12 contact the iron ring 2, due to the material properties of copper, they can maintain a stable clamping force and reduce damage to the iron ring 2.

This clamping method can ensure that the iron ring 2 maintains a stable position and posture during the processing, thereby improving the processing accuracy and efficiency.

[0025] When the machine tool starts to process the iron ring 2, the copper clamping jaws 12 and the balance buffer assembly are used together to ensure stability and safety during the processing. After the processing is completed, the clamping jaw cylinder 1 moves again to drive the copper clamping jaws 12 to release the iron ring 2, completing the entire clamping and processing process.

[0026] The automatic centering and balancing jaw mechanism for machine tool processing of the utility model realizes automatic centering and balancing clamping of the iron ring 2 through the coordinated use of the copper jaw 12 and the balancing buffer component, improves the processing accuracy and stability, reduces the scrap rate and production cost, and has broad application prospects.
