Description

An easily adjustable grinder

Technical field

The utility model relates to the technical field of grinders, specifically a conveniently adjustable grinder.

Background technique

A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding. They can process materials with higher hardness, such as hardened steel, carbide, etc.; also Can process brittle materials such as glass and granite.

Most of the existing fixtures have a simple structure and are unable to adapt to most workpieces. When grinding different workpieces, it is often necessary to replace different fixtures, which is very inconvenient. For example, the publication number CN217291831U discloses an automated CNC grinder that can easily adjust the fixture. The device adjusts the positions of slider one and slider two by driving components, so that the two sets of clamping plates can clamp items of different thicknesses, and the clamping plates themselves can be adjusted up and down, making it convenient to use the device. .

However, the above-mentioned device is not practical enough during use. The clamping plate in this device can only fix and clamp the object, and cannot adjust the position of the object while clamping. The side wall of the object can also be polished, which requires subsequent polishing. The items need to be clamped again, and the clamping plate of the device is inconvenient to disassemble, which makes it impossible to replace the clamping plate with a more appropriate clamping plate for items with special shapes, thus affecting the use of the device; in view of this, we propose An easily adjustable grinder.
