Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of machining, specifically relates to a part polishing clamping tool. BACKGROUND
[0002] Mechanical polishing is to remove a very thin layer of metal on the sample grinding surface by relying on the grinding and rolling of very fine polishing powder. Polishing is often used to enhance the appearance of products, prevent instrument contamination, remove oxidation, create a reflective surface, or prevent corrosion of pipes.
[0003] In the prior art, when polishing the surface of a part, especially the surface of a thin-walled part, the part is often held by hand for polishing. However, holding the part by hand can reduce the polishing accuracy. If a mechanical clamp is used, the thin-walled part can be deformed when clamped, reducing the part yield. UTILITY MODEL CONTENT
[0004] To solve the above problems in the prior art, the utility model provides a part polishing clamping tool for stably fixing a thin-walled part.
[0005] To achieve the above technical purpose, the utility model adopts the following technical scheme:
[0006] A part polishing clamping tool includes a bottom shell, a dustproof plate, and a support column. The top surface of the bottom shell is uniformly provided with mounting holes, and a limiting groove is arranged below the mounting holes. The side surface of the bottom shell is provided with air vents connected with an external vacuum pump. The dustproof plate is installed above the bottom shell, and the dustproof plate is uniformly provided with limiting holes corresponding to the mounting holes. The support column has a hollow tubular structure, and a limiting spring is installed at the bottom of the support column. The upper end of the limiting spring is fixed to the inner side of the mounting hole, and the limiting spring is installed in the limiting groove. The top of the support column extending out of the bottom shell and the dustproof plate is provided with a hollow rubber suction cup.
[0007] Further, a buffer foam is arranged on the inner bottom of the bottom shell, and an air vent net is arranged on the buffer foam.
[0008] Further, the upper surface of the dustproof plate is an arc-shaped dome.
[0009] Further, a filter valve is arranged at the center of the rubber suction cup on the support column.
[0010] According to the above technical scheme, the utility model has the beneficial effects that the utility model uses the uniformly arranged support column to support the polishing part. The vacuum pump draws the bottom shell to the rubber suction cup to negative pressure, adsorbs and fixes the thin-walled part placed on the support column, avoids the deformation of the part caused by the clamping tool during polishing, and improves the yield of the product.
