Grinding fixture and grinding machine

Abstract

The invention relates to a grinding jig and a grinding machine. The grinding jig is used to clamp the product to be polished, so as to polish the product to be polished through the grinding unit. The product to be polished includes an arc-shaped surface to be polished and lugs arranged on both sides of the surface to be polished; A clamping piece for clamping the product to be polished, a base for carrying the clamping piece and a limiting piece. When the clamping piece rotates relative to the base, the clamping piece can be in conflict with the limit piece respectively, so that the grinding units are respectively located at both ends of the surface to be polished; The second central axis of the grinding surface coincides so that the distance between the grinding surface of the grinding unit and the first central axis or the second central axis is constant. A grinding machine includes the above-mentioned grinding jig and a grinding unit. It has the advantages of more precise control of the grinding amount and higher grinding stability.

Description

Technical field[0001]The invention relates to the technical field of watch case processing, in particular to a polishing jig and a polishing machine.Background technique[0002]With the rapid development of technology in the electronics industry, smart watches are widely used. In the development process of smart watches, the watch case highlights its particularly important position. The material of the watch case is generally selected from plastic, metal or ceramic. During the production and processing of the watch case, the watch case will be polished, especially the metal watch case, because the surface is easy to scratch, so the polishing process is very important.[0003]When the watch case is processed, the outer surface of the shell is usually composed of a part processed by a lathe and a part processed by CNC (Computerized Numerical Control, computer numerical control technology). The intersection of the part processed by the lathe and the part processed by the CNC forms a knife ...

Problems solved by technology

[0004] Due to the large size of the traditional grinding machine, there are lugs used to install the strap at the strap installation. The lugs limit the structure of the case, making it difficult to grind the knife marks near the lugs with traditional grinding machines. Sanding is usually done by manually holding the case on a belt sander

Manual grinding makes it difficult to control the grinding angle and grinding amount, resulting in low grinding stability
