Description

Technical Field

[0001] The utility model relates to the technical field of metal part grinding, in particular to a grinding device for processing metal parts. Background Art

[0002] Sheet metal polishing involves processing the surface of sheet metal using specialized tools and techniques to achieve a smooth, burr-free finish and remove oxide layers. This process plays a crucial role in metalworking, significantly improving the quality, aesthetics, and service life of sheet metal parts.

[0003] In the process of grinding automobile sheet metal parts, the sheet metal parts themselves are relatively soft compared to other hard metals, and the secondary damage they suffer from the grinding mechanical movement during grinding is also greater than that of other hard metals. When the initial processing surface of the sheet metal parts is uneven, grinding them may cause damage to the surface.

[0004] The utility model with application number CN202323470048.2 discloses a metal forging grinding device, relating to the technical field of metal forging processing, and the utility model includes an operating table, the top of the operating table is fixedly connected to a support frame, and a lifting mechanism is provided inside the top of the support frame, the lifting mechanism includes a lifting shaft, one end of the support frame is fixedly connected to a first motor, and the output end of the first motor is fixedly connected to the lifting shaft, the outer surface of the lifting shaft is fixedly sleeved with a first bevel gear on both sides, the lower ends of the outer surfaces of the two first bevel gears are meshed and connected to the second bevel gear, the bottom ends of the two second bevel gears are fixedly connected to threaded rods, the bottom ends of the two threaded rods are respectively rotatably connected to the lower inner wall of the support frame, the outer surfaces of the two threaded rods are sleeved with sliders, and the opposite ends of the two sliders are fixedly connected to a lifting plate, and a rotating mechanism is provided inside the operating table. By setting the lifting mechanism, the height of the grinding head can be adjusted, and by setting the rotating mechanism, the metal forging can be driven to rotate.

[0005] This application achieves a better grinding effect by rotating the metal part to be processed and the grinding head at the same time. However, the flatness of the sheet metal part in the initial processing state is uneven. During grinding, the same grinding height will cause the average flatness of the sheet metal part to be insufficient when it is ground, resulting in inconsistent thickness after processing.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of the utility model is to provide a grinding device for processing metal parts which can effectively solve the above technical problems.

[0010] The fixing assembly includes a threaded member, a clamping groove, and a roller body; the threaded member is threadedly connected to the clamping groove, and the roller body is rotatably connected to the clamping groove;

[0011] The transmission assembly consists of a second motor, a first transmission rod, a second transmission rod, and a third transmission rod; a connecting shaft is installed at the output end of the second motor, and the connecting shaft is connected to the first transmission rod through a belt drive, the first transmission rod is fixedly connected to the roller body, and the first transmission rod and the second transmission rod are connected by a belt, and the second motor connecting shaft is connected to the end of the third transmission rod by a belt.

[0015] Furthermore, a blanking clamp is provided on one side edge of the device close to the cleaning roller.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the utility model is a grinding device for processing metal parts. When the sheet metal part is fixed on the clamping plate, it moves with the rotation of the chain, and passes through the roller body connected to the first transmission rod to perform initial pressing on the sheet metal part and flatten its bent part.

DETAILED DESCRIPTION

[0027] In the process of sheet metal grinding, the purpose of sheet metal grinding is to remove defects, burrs and oxide layers on the metal surface to obtain a smooth and neat appearance, turning the interior parts of the car into smooth and flat sheet metal.

[0028] The fixing assembly 3 includes a threaded member 31, a locking groove 32, and a roller body 33; the threaded member 31 is threadedly connected to the locking groove 32, and the roller body 33 is rotatably connected to the locking groove 32, and a threaded groove adapted to the threaded member 31 is provided in the locking groove 32; the roller body 33 is placed inside the locking groove that matches the locking groove 32, and the knob on the top of the threaded member 31 is manually rotated to move the threaded member 31 downward in the vertical direction of the locking groove 32, thereby abutting the roller body 33. At this time, the threaded member 31 does not penetrate the locking groove 32 and the roller body 33 at the same time, but only penetrates the locking groove 32 and abuts the end of the roller body 33 to prevent the roller body 33 from shaking when pressing the sheet metal part, thereby avoiding poor pressing effect.
