Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a grinding wheel machine matched with a rail cutting grinding wheel. Background Art

[0002] The grinding wheel machine mainly uses its grinding wheel to grind and cut the surface of the workpiece. Most grinding wheels use high-speed rotating grinding wheels for grinding and cutting. When cutting the workpiece, the existing desktop grinding wheel machine needs to fix the rail to be cut and move the handheld grinding wheel cutter up and down for cutting, or the grinding wheel cutter needs to be fixed and handheld to cut the rail; the traditional cutting method requires manual operation and cutting. Holding the rail material or the grinding wheel cutter for a long time will cause arm fatigue and low work efficiency.

[0003] For example, the patent publication number CN 202540101 U discloses a grinding machine that matches a rail cutting grinding wheel, including a grinding wheel cover, a grinding wheel motor disposed in the grinding wheel cover, a grinding wheel disposed in the grinding wheel cover and connected to the grinding wheel motor, a control box installed at the bottom of the grinding wheel cover that can control the start of the grinding wheel motor, and a movable dust collection box connected in series with the grinding wheel cover, wherein an adjustable baffle is provided at the cover opening of the grinding wheel cover; when using the grinding wheel machine, the position of the baffle is controlled to control the opening of the cover opening, reduce air leakage and dust, and the dust collection box can be used to centrally process dust, making it convenient for staff to clean the grinding wheel machine. Although the above structure can realize the grinding of materials by the grinding wheel machine, it is necessary to move the material to the grinding wheel for cutting when using it, which takes up a lot of manpower; and the grinding wheel cover is an integrated structure or a single-sided structure, and it is extremely inconvenient to replace the grinding wheel in the integrated structure, and the entire grinding wheel machine needs to be dismantled before replacing the grinding wheel, and the single-sided structure causes the grinding wheel cover to be unable to block the debris generated by cutting.

[0004] In order to solve the above problems, we provide a grinding machine that can cut rails at multiple angles, quickly fix rails, electrically control the movement of cutting wheels, and easily replace rail cutting wheels. Utility Model Content

After the replacement is completed, reverse the above steps to close the cover plate. When it is necessary to cut thicker rails, you can choose to flip the bottom rail before cutting, or cooperate with the longitudinal guide rail to move forward and backward to cut the side of the rail with the grinding wheel. This device can match the high speed and high-intensity cutting applications of the rail cutting wheel.

[0014] Beneficial effects: The device can cut the rails that need to be cut, and can adjust the angle of the rail cutting wheel to cut the side of the rail. During the whole process, there is no need to manually support the grinding wheel cutter and the rails that need to be cut to achieve cutting, and an openable cover is provided to facilitate the replacement of the grinding wheel.
