Description

Reliable and Durable Optical Projection Grinder Grinding Wheel Remover

【Technical field】

The invention relates to a grinding wheel removal device, in particular to a reliable and durable optical projection grinding machine grinding wheel removal device.

【Background technique】

When disassembling the grinding wheel on the optical projection grinding machine, the standard grinding wheel disassembly wrench that comes with the optical projection grinding machine is traditionally used, but the wrench is in the shape of a blind hole T-shaped sleeve. Tighten the main shaft of the machine against the bottom of the blind hole on the wrench, and turn the wrench clockwise forcefully to pull the grinding wheel out of the main shaft of the machine. Because the force handle of the wrench is too short, it is not easy to use force when disassembling the grinding wheel. During use, the force handle is often hit with a hard object, which is inconvenient to disassemble and takes a long time. After long-term use, the thread on the outer diameter of the wrench will be damaged. In the event of wear, slip and breakage, the entire wrench must be scrapped once the thread wear, slip and breakage occurs, and the use cost is high. How to improve the existing grinding wheel dismounting wrench is the content of the inventor's painstaking research.

As for the automatic propulsion time control device of the tool passivation machine described above, the push control member 3 is a bolt capable of being threadedly connected with the threaded through hole, and a parallel push surface 31 is provided at the end thereof.

As for the automatic propulsion time control device of the tool passivation machine as described above, the disassembly fixing seat 1 and the disassembly sleeve 2 are cylindrical, and the outer diameter of the disassembly fixing seat 1 is larger than the outer diameter of the disassembly sleeve 2 path.

Compared with prior art, the present invention has following advantage:

1. The invention can disassemble the grinding wheel more easily and conveniently, and save the disassembly time of the operator. The grinding wheel is ejected from the main shaft by controlling the push control part, and the end of the main shaft of the grinding wheel of the machine head is supported by the push control part. Force and reaction force remove the grinding wheel from the main shaft, and the disassembly force is balanced, which can effectively avoid damage or deformation of the main shaft of the grinding wheel of the machine head, prolong its service life while ensuring the accuracy of the main shaft, and effectively solve the problem of using the existing grinding wheel removal wrench. It is not easy to bear the force and the abnormal phenomenon of frequent slipping and breaking of the orifice thread.

2. In the present invention, the connecting external thread can be arbitrarily shortened by setting the thread depth. When the connecting external thread is worn or broken due to the long-term twisting of the flange nut, the sleeve can be disassembled and the connecting external thread can be continued to be used after being shortened. , to avoid the entire scrapping, replace the traditional passive wear type, and change it to a long-term use continuous compensation type, which saves the cost of use and is suitable for widespread promotion.
