Description

Technical Field

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

[0002] The piston is a component that reciprocates in the cylinder block of a car engine. The basic structure of a piston can be divided into the top, head and skirt. The top of the piston is the main part of the combustion chamber, and its shape is related to the type of combustion chamber selected. Gasoline engines mostly use flat-top pistons, which have the advantage of a small heat absorption area. Diesel engine pistons often have various pits on the top, and their specific shape, position and size must be adapted to the requirements of the diesel engine's mixture formation and combustion.

[0003] At present, after the piston is processed, it needs to be polished with polishing equipment to make its surface smoother. When the polishing equipment polishes the metal piston, the physical friction method is used to polish, which will cause the piston surface temperature to rise. When the staff takes the piston after polishing, the piston surface temperature is very high and they are easily burned by the piston. Other auxiliary tools need to be used, or the piston can be taken out after cooling, which affects work efficiency. Therefore, a polishing device for piston processing is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0024] Example 1:

[0025] This embodiment provides a piston surface polishing device, comprising:

[0026] Working box 1, the working box 1 includes a working chamber 2 and a recovery tank 3;

[0031] It can be seen from this embodiment that the piston is clamped by the clamping assembly 4 in the working chamber 2, and the condensation assembly 5 arranged on both sides of the working chamber 2 can spray condensate through the nozzle body 6 to flush the piston during the polishing process, thereby preventing a large amount of heat generated by physical friction during polishing and causing the piston surface temperature to rise. The first rotating assembly and the second rotating assembly cooperate with each other to realize multi-directional spraying of condensate and uniform heat dissipation, thereby solving the problem that the staff is easily scalded when taking the piston after polishing due to the high surface temperature of the piston, thereby improving work efficiency and production safety. The adsorption assembly arranged in the recovery pool 3 can adsorb metal chips in the recovery pool 3, facilitate collection, and improve work efficiency.

[0032] Example 2:

[0033] This embodiment provides a piston surface polishing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0034] The first rotating assembly includes:

[0035] A first motor 7 is provided on the outer surfaces of both sides of the working box 1;

[0036] The output shaft of the first motor 7 passes through the side wall of the working box 1 and is fixedly connected to the rotating base 8 . A cavity 9 is formed inside the rotating base 8 .

[0037] It can be seen from this embodiment that when the first motor 7 is working, the output shaft of the first motor 7 drives the rotating seat 8 to rotate, thereby changing the spraying angle of the condensed water.

[0038] Example 3:

[0039] This embodiment provides a piston surface polishing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0040] The second rotating assembly includes:

[0046] The driven bevel gear 15 is fixedly connected to the second rotating rod 13 , and the driving bevel gear 14 is meshed with the driven bevel gear 15 .

[0047] It can be seen from the present embodiment that when the second motor 10 is working, the output shaft of the second motor 10 drives the first rotating rod 11 to rotate, and the rotation of the first rotating rod 11 drives the active bevel gear 14 to rotate, thereby driving the driven bevel gear 15 to rotate, and the second rotating rod 13 also rotates accordingly. At this time, the nozzle body 6 rotates with the second rotating rod 13 to achieve a change in the spraying angle, so that the heat dissipation is more uniform.

This welding connection provides a more secure and stable connection. The mounting base 19 is connected to the movable end of the telescopic rotating bearing platform 18 (i.e., the upper end of the piston rod of the hydraulic telescopic cylinder) by welding. The setting of the mounting base 19 can place the object on the mounting base 19 when the polishing and grinding device is performing the object grinding work, providing a support for the object, so that the connection between the object and the polishing and grinding device is more stable. The base plate 20 is connected to the mounting base 19 by welding. The welding connection method can make the connection between the mounting base 19 and the fixed end of the base plate 20 more firm and stable. The fixed end of the hydraulic telescopic structure 21 is connected to the base plate 20 by welding.
