Auto parts grinding device

Abstract

The invention discloses a grinding device for automobile accessories. The grinding device comprises a frame. A support plate is arranged below a workbench. A circular ring tube is fixed on the supportplate. A rotating shaft is rotationally connected in the inner circle of the circular ring tube. A through hole is formed in the rotating shaft. An open hole is formed in the circular ring tube. A grinding head is fixed on the rotating shaft. Radiating holes are formed in the grinding head. The through hole is communicated with the radiating holes. A connecting pipe is connected to the circular ring tube. A collecting box is fixed on the frame. Collecting holes are uniformly distributed in the collecting box. A rotating rod is rotationally connected to the collecting box. A fixing seat is fixed on the rotating rod. A negative-pressure pump is fixed on the frame. The negative-pressure pump is communicated with the collecting box. The negative-pressure pump is communicated with a gas outletpipe. A driving mechanism is arranged on the frame. Compared with the prior art, by the adoption of the scheme, the gas output by the negative-pressure pump can carry heat generated by the grinding accessories out of the grinding head, the hardness of the grinding head cannot be reduced, and therefore the grinding quality is ensured; and through the driving mechanism, the accessories rotate intermittently, and the grinding efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of accessory grinding equipment, in particular to an auto accessory grinding device. Background technique [0002] Auto parts are a product of each unit that constitutes the whole car; most auto parts are stamped parts that are integrally formed. After the parts are stamped, there will be many burrs on the parts. The operator will polish the burrs to achieve the use Requirements: Generally, manual grinding is used to deal with burrs. During the grinding process, the grinding degree of parts is not well controlled, which also leads to unstable grinding quality, and a large amount of heat will be generated during the grinding process. If the heat is not If it is released in time, the temperature of the grinding head will be too high and the hardness will be reduced. The hard burrs on the accessories will react on the surface of the grinding head, making the surface of the grinding head uneven, which not only reduces the...

AI Technical Summary

Problems solved by technology

[0004] The above scheme solves the problems in the prior art by providing a cavity in the grinding head and a cooling medium in the cavity, so that the grinding head can dissipate heat when grinding, but the above scheme still has the following problems: The medium is enclosed in the cavity, and its total amount is fixed. Although it can achieve a certain heat dissipation effect, after a period of grinding, the heat on the grinding head will accumulate more and more, and there will still be a large amount of heat that cannot be dissipated in time. It will still cause the hardness of the grinding head to decrease due to high temperature; the accessories cannot be changed to the grinding position. It is necessary to stop grinding after the grinding device has polished one side of the accessory, and the operator can change the position of the accessory to completely polish the entire accessory. Long stay in the middle, low efficiency
