Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically a grinding machine with an anti-offset structure. Background Technology

[0002] A grinding machine is a machine tool that uses abrasive wheels to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasive wheels and free abrasives such as honing machines, ultra-precision machining tools, belt grinders, lapping machines, and polishing machines. Existing grinding machines usually fix the workpiece in place using a vise or a magnetic platform. However, while vises and magnetic platforms can stably fix some relatively regular-shaped workpieces, for some irregularly shaped parts, due to the limited contact area, workpiece displacement is prone to occur during the grinding process, thus affecting the grinding effect.

Then, by rotating the threaded rod 11 through the rotating rod 12, multiple sets of clamping plates 10 clamp various parts of the irregular part respectively. This allows the device to stably fix irregular parts with relatively complex structures, reducing the possibility of deviation of irregular parts during grinding and improving the stability of the grinding process.

[0031] This grinding machine with an anti-offset structure works in conjunction with a hydraulic cylinder 1406, a first lead screw 4, a moving table 2, a second lead screw 1403, and a moving plate 1402.
