Technical Field

[0001] The utility model relates to the technical field of angle sensor production, in particular to a grinding device for angle sensor production parts. Background Art

[0002] A sensor is a detection device that can sense the information being measured and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. The sensor is assembled from many parts during the manufacturing process. There will be some burrs on the surface edges of the parts after processing and cutting. During the assembly process, the parts are not of the same size and need to be polished. Generally, the staff hold the parts in their hands and polish them with a grinder, which involves certain risks.

[0003] For example, Chinese patent announcement No. CN219945541U discloses a grinding device for sensor production parts. When in use, turn on the lighting, hold the connecting disk so that the connecting disk cannot rotate inside the fixed rod, rotate the screw, and the screw moves inside the connecting disk, move the two sets of clamping blocks closer to each other, place the sensor part between the two sets of clamping blocks, clamp the sensor part through the clamping blocks, hold the grinder and pull it downward, the connecting column slides inside the limit block, the partition at the top of the connecting column squeezes the spring, and the angle of the grinder can be adjusted by rotating the cylinder at the top of the grinder inside the connecting block, and the rotating rod drives the worm to rotate, and the worm rotates to drive the worm wheel to rotate, and the worm wheel rotates to drive the clamping block to rotate together, so that the clamped parts are rotated, and different parts are polished.

[0004] However, the grinding device for sensor production parts in the above application requires employees to manually grind the parts, which is inefficient and has insufficient grinding accuracy. Moreover, after the two clamping blocks clamp the two sides of the parts, it is not convenient to grind the sides. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a grinding device for producing parts of angle sensors. Utility Model Content

The part body is inserted into the inside of the plug-in hole on the fixing table, and then the electromagnet is energized to adsorb and fix the iron part. At the same time, as the magnetic field changes, the magnetorheological fluid inside the rubber airbag is transformed from a low-viscosity Newtonian fluid to a high-viscosity, low-fluidity Bingham fluid as the magnetic field changes, thereby clamping and fixing the inserted part of the part body and improving the stability of the clamping.

[0013] A further improvement is that the adjusting and polishing device includes a lifting motor, a transmission member, a connecting rod, an electric push rod, and a polishing block.
