Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to a processing table fixing structure with impact-resistant flexible contact. Background Technology

[0002] In the fields of machining, inspection, and assembly, the stable fixation of workpieces on the machining table is a prerequisite for ensuring accuracy, safety, and efficiency. Traditional rigid contact or suction cup structures both have problems with workpiece clamping. For example, rigid clamping can easily cause deformation or surface indentation of thin-walled, brittle, or pre-machined workpieces at the contact point. Suction cup structures have extremely high requirements for the flatness and smoothness of the workpiece surface; even a slight scratch or unevenness can lead to air leakage and pressure loss, resulting in clamping failure. Therefore, both have clamping problems, which reduce the yield rate of finished products due to poor clamping during workpiece processing. In modern machining, flexible clamping structures are used to achieve good clamping performance and provide impact-resistant clamping to absorb external impact forces and provide a buffering effect. However, such flexible clamping structures cannot be adapted and adjusted. For example, when dealing with some irregularly shaped workpieces, two sets of symmetrically arranged clamping structures may not be able to form a firm and good contact due to the irregular shape, affecting the actual clamping and fixing.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

The outer side of the annular base 102 is provided with an annular adjustment groove 103 for forming a circumferential position adjustment. Several sets of clamping components 200 for clamping and fixing workpieces are installed on the outer side of the annular base 102. The clamping components 200 include a cylinder base 201, a clamping cylinder 202, a main clamping base plate 205, a flexible contact plate 206, and an arc-shaped slider 210. A clamping cylinder 202 is fixedly connected to the inner side of the cylinder base 201. A main clamping plate 205 is fixedly connected to one end of the clamping cylinder 202 near the center of the annular platform 102.

In the process of clamping the workpiece, a negative pressure device generates a negative pressure suction force, which assists in adsorbing the workpiece through the negative pressure suction hole 207, and presses and fixes it from above as needed.

[0031] Based on the first embodiment described above, further, during workpiece clamping, a negative pressure suction force is generated by a negative pressure device, and then the workpiece is transferred and conveyed via a negative pressure conduit 208 and a negative pressure chamber. During the movement adjustment of the clamping assembly 200, the workpiece is assisted by a bellows 214, and then the workpiece is assisted by a negative pressure suction hole 207. According to the workpiece clamping requirements, the pressure plate 108 can be moved down by the pressure telescopic rod 107 from above to press and fix the workpiece from above, thereby assisting in clamping.
