Description

Technical Field

[0001] The utility model belongs to the technical direction of a precision mechanical component grasping structure, and specifically relates to a precision mechanical component grasping structure. Background Art

[0002] Precision machining is a process of changing the size or performance of a workpiece by machining machinery. It can be divided into cold machining and hot machining according to the temperature state of the workpiece being machined. Generally, machining at room temperature without causing chemical or physical phase changes in the workpiece is called cold machining. In the process of precision machining, grasping tools for precision mechanical parts are often used, but existing grasping tools can only be clamped in a fixed position, and existing grasping tools usually do not have a buffer structure, which leads to not only high limitations in actual operation, but also sometimes damage to precision mechanical parts due to excessive grasping force, and fail to achieve the desired effect.

[0003] In the prior art, a Chinese patent document with publication number CN114055446A is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a precision mechanical component grasping structure with multi-directional adjustment, the precision mechanical component grasping structure with multi-directional adjustment includes a base, a support rod installed on the base, and a top plate arranged on the side end of the support rod. When the precision mechanical component is grasped, the shell is driven by the adjustment mechanism to adjust the grasping position, and then the grasping mechanism is driven by the electric telescopic rod to drive the clamping block to open and then contract, thereby realizing the grasping of the precision mechanical component. In this process, the clamping block squeezes the protection spring and moves toward the abutment plate through the guide rod, and the guide rod moves in the through hole of the fixed plate, thereby alleviating the clamping force on the precision mechanical component, so that the precision mechanical component is effectively protected when the clamping block is grasped. Finally, the multi-directional adjustment of the grasping structure is realized, and the precision mechanical component can be grasped stably.

[0004] The prior art has the following problems: the gripping component cannot selectively fix the two ends of the processed product, and the product may slip due to vibration during processing.
