Abstract

The present invention proposes a self-centering multi-axis linkage type internal expansion clamping mechanism and clamping method, comprising: a fixed seat; A plurality of mounting slots for the insert, and a spring pin mounting slot is opened on the mounting slot of the insert; the insert and the mounting slot of the insert are detachably connected, and a spring pin movable groove is opened through it; the spring pin is set through the spring pin movable groove In the spring pin installation groove, the spring pin is provided with a spring pin slope near the through hole of the mandrel; the fixed block is detachably connected to the other end of the mandrel, and a blind hole is opened on the fixed block; the elastic member is arranged in the blind hole, The upper end abuts against the fixed block; the spring pin pressing block is located in the through hole of the mandrel and connected with the lower end of the elastic member; the lower surface of the spring pin pressing block is provided with a pressing block slope matching the spring pin slope. In the internal expansion clamping mechanism proposed by the invention, the elastic pins are stressed at the same time, the expansion force on the inner wall of the product is uniform, the positioning is accurate, and the positioning size and precision of the product itself have little influence on the detection.

Description

A self-centering multi-axis linkage type internal expansion clamping mechanism and clamping method technical field The invention belongs to the technical field of clamping tooling, particularly a kind of self-centering multi-axis linkage type internal expansion clamping mechanism and Clamping method. Background technique [0002] In the manufacturing industry, it is often necessary to secure products for subsequent processing. Various types of clamping currently commonly used Or locking mechanisms, such as manual clamping tool clamps, quick clamps, splints, and other types of cylinders and valves such as pneumatic clamping devices Wait. Due to the unavoidable dimensional tolerance of the product in the previous process, the use of these tooling to fix the production The gap error caused by these dimensional tolerances cannot be completely eliminated, resulting in the final product accuracy depending on the product. The dimensional accuracy of each process of the pr...
