Description

Technical Field

[0001] The utility model relates to the technical field of metal piston processing, in particular to a metal piston surface polishing device. Background Art

[0002] The piston is a key component of the automobile. It consists of a top, a head, and a skirt. It can be made of iron alloy or magnesium-aluminum alloy. The metal piston is a reciprocating part used in engines, hydraulic cylinders, and cylinders. The metal piston is usually made of aluminum alloy, steel, and other materials. It has high sealing performance and wear resistance. In order to improve the processing efficiency of the metal piston, a polishing device is needed. However, the existing polishing device still has the following shortcomings:

[0003] For example, the utility model with application number 201920777051.3 discloses a novel metal piston surface polishing device, which facilitates the clamping of the piston by setting a fastening turntable, a wheel frame, an upper turntable and a lower turntable. The end face of the piston is polished after being fixed, and the piston can be rotated on the fixture support to make the polished end face more uniform and more efficient. The force of the piston acting on the polishing belt can be adjusted by setting a fixture support and a slide rail. However, similar to the comparative documents of the above-mentioned application, when the existing polishing device is used, since most metal pistons are small in size, it is not easy for the polishing device to limit the metal piston, which causes the piston to be easily displaced during the processing, thereby affecting the polishing, resulting in reduced practicality and reduced efficiency of the polishing device.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a metal piston surface polishing device is proposed. Utility Model Content

[0015] 1. The utility model can avoid the problem that most metal pistons are small in size, which makes it difficult for the polishing device to limit the metal piston, resulting in the piston being easily offset during processing, thereby affecting polishing and causing the problem of reduced practicality of the polishing device, by setting a polishing component. The servo motor is fixedly installed on the outside of the protective frame via fasteners, and the output shaft of the servo motor is connected to the first gear through a coupling.

[0016] 2. The utility model can avoid the situation that most polishing devices do not have the performance of cooling materials when the metal piston surface polishing device is used, which causes the surface temperature of the metal piston to be too high after friction polishing, affecting the subsequent material feeding and reducing the use efficiency of the polishing device, by setting the dustproof component. The water collecting plate is fixedly installed on both sides of the inner part of the protection frame through fasteners, and the water outlet is fixedly installed on the outer side of the water collecting plate with the fasteners, and the water pump is fixedly installed on both sides of the outer side of the protection frame.

A large amount of cooling water is supplied, and the water pump is connected to the water tank, so that when the water pump is working, the cooling water inside the water tank is sucked and transported to the inside of the water collecting plate, and sent out through the water outlet, thereby cooling the metal piston while preventing dust from being scattered during the polishing process. The used cooling water then enters the water collecting chamber opened inside the protective frame, and the cooling water with impurities is collected by the water collecting frame arranged at the lower end of the water collecting chamber. The cooling water in the water collecting frame enters the filter box by gravity and is filtered and processed, and then enters the water tank again, thereby completing the recycling of cooling water and improving the use efficiency of the polishing device.
