Description

Technical Field

[0001] The utility model relates to the technical field of precision device processing, in particular to a grinding and polishing device. Background Art

[0002] Precision device processing is a manufacturing process with extremely high requirements on size, shape and surface quality. These parts are usually used in high-precision equipment and mechanical devices, such as aerospace equipment, medical equipment, automobiles and electronic products. In the process of precision device processing, it is generally necessary to remove tiny burrs and unevenness on the surface of parts through grinding and polishing, improve surface finish and improve performance. A grinding and polishing device is proposed here.

[0003] According to the search, Chinese patent literature, announcement number: CN215470380U, discloses a grinding and polishing device for precision parts processing, which is to place the part to be polished in the grinding groove, and then press down the lower pressure rod to move it out of the slot with the telescopic rod, then turn the hand to rotate the gear, and then the two cross bars will respectively move with the two clamps to the position to fix the grinding part, after releasing the lower pressure rod, the telescopic rod will engage with the slot again under the action of the second spring, and then control the cylinder to move the grinding groove to the appropriate position, and finally turn on the motor to carry out polishing with the grinding disc. However, in actual use, the device can only move the height position of the grinding groove and the workpiece through the cylinder, and cannot adjust the horizontal position of the workpiece. Therefore, there are certain limitations when grinding, and it is difficult to perform comprehensive processing on workpieces of different shapes and sizes. Utility Model Content
