Description

Technical Field

[0001] The present invention relates to the technical field of machine tools for machining mechanical spare parts, and specifically relates to a grinding device for a machine tool. Background Art

[0002] In modern mechanical manufacturing, the requirements for product quality and production efficiency are getting higher and higher. Traditional mechanical grinding methods have problems such as operator skill dependence, low efficiency, and high maintenance costs, which limit the development of mechanical processing. An advanced grinding device for a machine tool can automate control, improve machining accuracy, reduce manual intervention, and improve production efficiency to meet the market's demand for high-quality and high-efficiency processing.

[0003] The utility model patent with the patent publication number CN217291646U discloses a grinding device for mechanical processing, which relates to the field of mechanical processing. This patent includes a processing table, inside which a grinding machine main body is movably connected. A regional grinding mechanism is provided on the processing table. The regional grinding mechanism includes a motor, on which an irregular bevel gear is fixedly connected. A first lead screw is fixedly connected to the irregular bevel gear. A second lead screw is rotatably connected to the inner side wall of the processing table. A bevel gear is fixedly connected to the second lead screw. A connecting block is threadedly connected to the first lead screw. A movable frame is fixedly connected to the connecting block. An installation block is threadedly connected to the second lead screw. A limiting frame is fixedly connected to the installation block. When the motor of this grinding device for mechanical processing works, it drives the first lead screw to rotate, and at the same time drives the second lead screw to rotate intermittently, driving the grinding machine main body to move longitudinally along the limiting frame and also driving the grinding machine main body to move laterally along the movable frame, so as to realize the automatic grinding of the steel plate within the area inside the processing table by the grinding machine main body.

[0004] However, the current grinding device for mechanical processing has the following problems: This grinding device for mechanical processing is not convenient for cooling the surface of the workpiece in time during the grinding process, which will cause the workpiece to be deformed by heat. And the burrs after drilling will remain at the drilled holes of the workpiece. If not processed in time, the burrs will scratch the workpiece, resulting in a decline in the quality of the product. Therefore, we propose a grinding device for a machine tool. Summary of the Invention
