Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, and in particular relates to a sheet metal grinding device for chassis production. Background Technology

[0002] Military electronic enclosures are widely used in military instruments, meters, electronics, communications, automation, and precision machinery. Their structure consists of an aluminum alloy frame, ABS, MDF, plywood, metal plates, etc. for the front panel, and T-joints, door strips, handles, locks, etc. as accessories.

[0003] In the production process of electronic chassis, sheet metal is used as the raw material. However, the purchased sheet metal is often too large to be directly stamped. It is necessary to first cut the sheet metal to the required dimensions, and then stamp the cut sheets to form sheet metal parts. Multiple sheet metal parts are then fixedly connected using positioning fixtures to form the chassis. During the cutting process, burrs are generated on the cut edges, which can easily cut the workers' arms. Therefore, a grinding device is used to grind the cut edges to remove the burrs.

[0004] The working principle of existing grinding devices is as follows: the sheet metal part is fixed on the worktable, and the worktable is moved towards the high-speed rotating grinding roller by the moving drive structure, so as to perform grinding operation on the sheet metal part. Since the relative movement between the sheet metal part and the grinding roller is simple, the grinding efficiency of the sheet metal part is reduced. Therefore, it is urgent to design a sheet metal grinding device for chassis production to solve the above problems. Utility Model Content

[0032] Work process:

[0033] During operation, the sheet metal parts are placed on the negative pressure adsorption platform 6, and the negative pressure vacuum pump assembly inside the negative pressure base station is started, so that the negative pressure adsorption platform 6 and several vacuum adsorption holes generate negative pressure adsorption force to adsorb and fix the sheet metal parts, thereby realizing the quick clamping of the sheet metal parts.

[0034] After the sheet metal parts are clamped, the lifting motor 8-1 is started, which drives the lifting base 2 to rise, thereby raising the clamped sheet metal parts to the position where the grinding roller assembly 5 can grind the sheet metal parts. Then, the lead screw motor 3-1 and the swing motor 9-1-1 are started, which drive the sheet metal parts clamped on the negative pressure adsorption table 6 to move laterally towards the grinding roller assembly 5 along the transverse guide rail 3-3. At the same time, the sheet metal parts are moved back and forth along the swing guide rail 9-3, which improves the grinding and polishing efficiency and the grinding and polishing effect of the sheet metal parts. During the grinding process, the dust hood 4 and the suction fan can collect the generated dust.
