Description

A gate removal and grinding device Technical Field

[0001] This utility model relates to the technical field of grinding equipment, and in particular to a gate removal grinding equipment. Background Technology

[0002] The top cover of a photovoltaic inverter series includes the panel body, with a mounting groove at the lower end. This is typically manufactured using aluminum die-casting. Correspondingly, one side of the top cover has a gate formed during casting, which is usually machined using a saw or milling machine. After the gate is removed, the end of the panel body where the gate was removed needs to be ground smooth to eliminate cutting marks and improve the surface finish. This grinding process can be performed on a grinding machine or manually.

The milling device 2 and the grinding device 3 are movably mounted on the frame 1. The mounting frame 4 is movably mounted on the frame 1 and located on one side of the milling device 2 and the grinding device 3 for mounting a workpiece 8. The milling device 2 has a milling plane, and the grinding device 3 has a grinding plane, which are parallel to the milling plane. The milling device 2 and the grinding device 3 move synchronously or asynchronously. The milling device 2 first cuts and removes the lateral gate of the workpiece, and then the grinding device 3 moves to grind the side of the workpiece. Optionally, the milling plane and the grinding plane are basically flush, and the grinding plane slightly exceeds the milling plane to constitute the grinding process.

[0037] The two ends of the tension spring 41 are connected to the frame 1 and the mounting bracket 4 respectively; at least one side of the mounting bracket 4 is provided with a positioning device 5 for positioning the workpiece 8.

[0038] Specifically, in this embodiment, a milling device 2 and a grinding device 3 are movably and integrally connected side-by-side on one side of the frame 1. The grinding device 3 is located on one side of the milling device 2. The milling device 2 first performs a milling operation on the workpiece 8, and then the grinding device 3 grinds the workpiece to prevent burrs and cutting marks from affecting its appearance.
