AI Technical Summary
Technical Problem
The flat threads of existing bearing machining positioning fixtures wear out during long-term use, resulting in poor meshing accuracy and affecting positioning performance.
Method used
The system employs a combination structure of worm gear, worm wheel, and connecting threaded rod. The worm gear is rotated by a positioning knob, the worm wheel moves the adjusting block of the connecting threaded rod, and the hinge and movable block cooperate to achieve radial and axial positioning of the bearing, thereby enhancing positioning stability.
Benefits of technology
It improves the service life and positioning accuracy of the three-jaw chuck, and extends the service life of the positioning fixture.
