Description

Technical Field

[0001] This utility model relates to the field of thread grinding machine technology, specifically a grinding structure for a thread grinding machine. Background Technology

[0002] A thread grinding machine is a device used for high-precision thread machining. The grinding structure, as the core component of the thread grinding machine, controls the synchronous rotation of the workpiece and grinding wheel according to the lead ratio, and drives the grinding wheel to move along the workpiece axis. Combined with precise feed and shape matching, threads are formed layer by layer through grinding. Existing grinding structures are typically equipped with only a single grinding wheel. Limited by the shape, grit size, and fixed mounting position of the grinding wheel, when machining complex thread structures, it is necessary to frequently change different grinding wheels, and even transfer the workpiece between multiple thread grinding machines to complete different processes. This not only increases the risk of clamping errors but also leads to reduced machining efficiency and increased costs, especially in mass production where the contradictions are more pronounced. Utility Model Content

[0003] In view of the defects of existing grinding structures, the technical problem to be solved by this utility model is to provide a grinding structure for a thread grinding machine that does not require the replacement of grinding wheels, improves processing efficiency, and reduces production costs.

[0004] To achieve the above objectives, according to one aspect of this utility model, the present utility model is implemented through the following technical measures: a grinding structure for a thread grinding machine, comprising a swivel head, a spindle seat, an electric spindle I, an electric spindle II, and a worm spindle assembly, wherein the worm spindle assembly includes a worm gear grinding spindle, the spindle seat is rotatably connected to the swivel head, the bottom of the spindle seat is provided with a spindle hole I, a spindle hole II, and a worm shaft hole, the spindle hole I, the spindle hole II, and the worm shaft hole are located on different horizontal planes, the electric spindle I is disposed in the spindle hole I, the electric spindle II is disposed in the spindle hole II, the worm gear grinding spindle is disposed in the worm shaft hole, and different grinding wheels are disposed on the electric spindle I, the electric spindle II, and the worm gear grinding spindle.

[0005] Furthermore, the spindle hole II is higher than the spindle hole I, and the spindle hole I is higher than the worm shaft hole.

[0006] Furthermore, the worm gear spindle assembly includes a worm gear grinding spindle, a pulley assembly, and a servo motor. A motor frame is provided on one side of the spindle seat, and a worm shaft hole is opened at the bottom of the motor frame. The servo motor is mounted on the motor frame.

[0007] Furthermore, the electric spindle I is a permanent magnet double-headed electric spindle, with a fine grinding wheel and a coarse grinding wheel respectively on both sides of the electric spindle I.

[0008] Furthermore, the electric spindle II is a permanent magnet single-head electric spindle.

[0009] Furthermore, the swing head is provided with a swing head shaft, and the top of the main shaft seat has a swing head shaft hole. The swing head and the main shaft seat are connected by the swing head shaft, and the swing head controls the rotation of the main shaft seat through the swing head shaft.

[0010] Furthermore, the swing head is fixed to the lifting device.

[0011] Compared with the prior art, the advantages of this utility model are as follows: The grinding structure of this thread grinding machine can be adjusted by adjusting the height of the grinding structure and the angle of the spindle head so that the spindle grinding wheel of the corresponding process contacts the workpiece for processing. The entire processing can be carried out on the same thread grinding machine without changing the grinding wheel, thereby improving processing efficiency and reducing production costs.
