A device for positioning and grinding the surface of a computer main case

Abstract

The invention discloses a surface positioning and polishing device for a computer mainframe box, and relates to the technical field of automatic polishing devices. The device comprises a base, a planepolishing mechanism, a positioning mechanism and a protrusion polishing mechanism; and a conveying belt is mounted at the upper end of the base. The conveying belt and the plane polishing mechanism are arranged on the base, so that the top end and the adjacent side end of the mainframe box can be polished at the same time; then, after the mainframe box is conveyed to the positioning mechanism andfixed, the side surface and corresponding fillets of the mainframe box can be polished automatically at the same time, so that the polishing efficiency is further greatly improved; by arranging a cross-shaped polishing frame driven by the same second drive motor, the completion of polishing of the protrusion end surface is guaranteed; and then, a sliding ball is provided in a second guide groove,and two symmetrically-arranged grinding wheels can complete polishing of protrusion slopes with different inclination angles along opposite movement tracks, so that synchronous and effective polishing of the fillets of the end surfaces of the mainframe box is synchronously implemented.

Description

technical field [0001] The invention relates to the technical field of automatic grinding equipment, in particular to a positioning grinding device for the surface of a main computer case. Background technique [0002] The processing flow of the computer main box is: punch programming, sheet metal punching (cutting), bending, welding, grinding, baking, installation and finally packaging. After the welding process is completed, the existing equipment is in the process of grinding. Install grinding rollers, grinding wheels and felt wheels to grind the different end faces of the workpiece respectively. [0003] However, there are still certain disadvantages in the use of the prior art: 1. Grinding the different end faces of the workpiece separately will cause the last polished end face to generate burrs towards its adjacent end face at the end of the grinding, and place them in the fillet , and when grinding to the adjacent side end face, the burr will reversely rotate to the ...

[0003] However, there are still certain drawbacks in the use of the prior art: 1. Grinding the different end faces of the workpiece separately will cause the last polished end face to generate burrs towards its adjacent end face at the end of the grinding, and place them in the fillet , and when grinding to the adjacent side end face, the burr will reversely rotate to the previous grinding end face, in order to completely remove the burr, reciprocating grinding is required, and the grinding efficiency is even lower when the degree of automation is not high; 2. Most of the current computers In order to reduce the floor space and not reduce the internal storage space, the main engine will protrude a part of the box from the side end of the bottom surface which is smaller than the original one, to achieve the above purpose, but the existing grinding device cannot effectively polish the protruding The raised part of the box, and the bevel formed by the raised edge and the side end cannot be effectively sanded
