Problems solved by technology

[0002] For precision CNC machining, the fixture is also a part of the quality control of the machining. If the general air cylinder or oil cylinder is used for pressing and positioning, the product cannot meet the automatic correction function during the clamping process, and the manufacturing process will inevitably affect the product processing accuracy and production efficiency. , and equipment utilization
At present, most of the processing fixtures with automatic correction function adopt the combination of hydraulic drive or numerical control drive and PLC control panel. The overall structure is relatively complicated, the input cost is high, the operation procedure is relatively cumbersome, and the operable objects and range have certain limitations. The repair and maintenance of permanent equipment is more difficult and the structure is more complicated

Abstract

The invention discloses a positioning fixture structure for automatically correcting gear drive. One group of positioning components are symmetrically arranged on each side of a mounting base plate main body; a self-centering bearing is sheathed outside the lower part of a guiding and connecting column, and a transmission gear is arranged above the self-centering bearing. The bottom of each positioning component is provided with a rack device and a coaxial transmission double-gear, the coaxial transmission double-gear comprises an upper gear and a lower gear from top to bottom, the lower gear is meshed with the rack device, and the upper gear is simultaneously meshed with the transmission gear. The automatic correction of positioning during precision numerical control machining of products is completed through gear transmission, and the operation is convenient. The operation of gear transmission requires the support of power, so that a simple cylinder for driving is designed on the structure. The gear transmission is powered via a factory internal air source required by machining equipment per se without external hydraulic or electric power. By using the positioning correction mode of gear transmission identical to thread pitch, the gear transmission has double advantages of good transmission accuracy and good positioning property.
