Feed fine adjustment mechanism and trimming module

Abstract

The utility model discloses a feed fine adjustment mechanism and trim module, this mechanism includes: base, it is equipped with slide rail, sliding block, sliding connection in slide rail, base is connected with mounting block in the retreat direction of sliding block, and sliding block is equipped with inner chamber, fixed block, it is located in the inner chamber and is fixedly connected to the base, micrometer, it is installed to mounting block, and micrometer is equipped with movable thimble, and movable thimble is towards sliding block, elastic member, it is located in the inner chamber, and the both ends of elastic member abut respectively in the inner side wall of fixed block and sliding block, and elastic member has the elastic force direction towards movable thimble, so that sliding block and movable thimble keep abut. Because sliding block and movable thimble keep synchronous movement all the time, therefore sliding block has the same stroke accuracy with movable thimble, just select stroke accuracy in 0.02mm below micrometer can satisfy the requirement of high-precision feed fine adjustment.
