Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, in particular to a polishing device for machining mechanical parts. Background Art

[0002] Polishing of mechanical parts is a surface processing technology that aims to improve the appearance and surface quality of parts through physical or chemical methods. In the process of mechanical manufacturing, due to various factors such as casting, forging, machining, etc., defects such as burrs, scratches, and oxide scale may appear on the surface of parts, which not only affect the appearance of the parts, but also may have an adverse effect on their performance and service life. Therefore, polishing has become one of the important processes to improve the quality of parts;

[0003] The utility model with application number 202120135145.8 discloses an iron plate surface polishing device for machining mechanical parts. The device is provided with a clamping mechanism, and the iron plate is squeezed simultaneously by a clamping plate to achieve fixation. The clamping pad can increase the stability of the clamping. When the iron plate is relatively large, the rotating bolt can be adjusted, and one bolt is constantly approaching the iron plate, and the other bolt is constantly moving away from the iron plate, so that the iron plate is horizontally offset, and then tightened, so that the position of the polishing module aligned with the iron plate changes, thereby polishing the entire iron plate. A cleaning and collecting mechanism is provided, and water is sprayed from a micro-sprinkler through a water spray pipe to wash away the iron filings on the iron plate. The iron filings enter the interior of the waste liquid collection box with the water through the rectangular groove, and are filtered by the sieve plate. The waste water enters the bottom of the sieve plate, and the iron filings are separated and left on the sieve plate. The iron filings are recycled by pulling the iron filing collection tube out of the sieve plate, saving raw materials and preventing waste.

[0004] However, in the above-mentioned iron plate surface polishing device for machining mechanical parts, the polishing module is fixed in a horizontal position, and the surface of the iron plate cannot be fully polished. The rotating bolt needs to be manually adjusted to push the iron plate to move, which affects the polishing effect. When the above-mentioned iron plate surface polishing device for machining mechanical parts is polishing, the micro-nozzle flushes the surface of the iron plate, so that the waste water containing iron filings can only flow down through the edge of the iron plate, and it is easy for iron filings to remain on the surface of the iron plate and affect the polishing work. Therefore, the utility model proposes a polishing device for machining mechanical parts to solve the problems existing in the prior art. Utility Model Content

[0005] In view of the above problems, the purpose of the utility model is to propose a polishing device for machining mechanical parts.

The first motor drives the rotating bin to rotate and tilt, so that the water flow sprayed from the spray pipe can flush away the iron filings, thereby effectively preventing the iron filings from remaining on the surface of the iron plate after polishing and affecting the polishing work.

When mobile polishing is required, the motor drives the transverse screw 5 and the longitudinal screw 6 to rotate back and forth respectively, driving the moving block 7 to move horizontally and vertically respectively, so that the polishing disc 11 can fully polish the iron plate, which solves the problem that the polishing module is fixed in the horizontal position and the rotating bolt needs to be manually adjusted when the iron plate moves, and the surface of the iron plate cannot be fully polished.
