AI Technical Summary
Technical Problem
The top of the traditional gear hobbing machine cannot rotate, which affects the accuracy of processing products and poses a risk of wear and tearing the center hole of the product.
Method used
The bidirectional screw and nip plate structure are adopted. The bidirectional screw is driven to rotate through a motor, which drives the nip plates to approach each other. The movable roller comes into contact with the top-point outer wall, and the top-point is clamped in the assembly hole to achieve top-point rotation.
Benefits of technology
Improves processing accuracy, reduces the risk of top wear and extends the service life of the equipment.

Abstract
The utility model relates to the field of gear hobbing machines, in particular to a tip replacement structure of a gear hobbing machine, which comprises a mounting seat, an assembly hole is arranged at the center of one end of the mounting seat, a tip is arranged in the assembly hole, a fixing groove is arranged on the outer wall of one side of the mounting seat, and a fixing structure is arranged at the center of the assembly hole of the fixing groove. The fixing structure comprises movable grooves formed in the mounting base and located in the centers of the two ends of the fixing groove, a two-way screw rotationally connected to the fixing groove and located at one ends of the movable grooves, a mounting groove formed in the mounting base and located at the bottom of the fixing groove, and a motor mounted in the mounting groove. The center is connected with the contact surface through the first bearing, the second bearing and the movable roller, so that abrasion is reduced after the center rotates, the first dustproof cover and the second dustproof cover are matched with the sealing ring to seal the interior of the assembly cavity, dust prevention and sealing are facilitated, and operation stability is guaranteed; abrasion is reduced, and the service life is prolonged.
