Problems solved by technology

The traditional technology is realized by fixing the piston ring on the piston body. However, when the compressor is working, the friction between the piston and the cylinder wall of the cylinder will generate heat, which will easily deform the piston ring, resulting in poor airtightness and increased friction. , affecting the working efficiency and service life of the air conditioning compressor

Embodiment 1

[0036] On the basis of the above-mentioned scheme, in this embodiment, before the step S5, a step S1 is also included: punching a center hole on the piston blank, and performing a turning process on the piston blank after the center hole is punched; in addition, on the piston, The punched center hole is the thimble hole. During the processing, the blank on the surface of the piston can be removed through the above process for subsequent processing to ensure the quality of the piston processing.

[0037] Based on the above method, the specific steps of piston processing in the present embodiment are as follows:

[0038] S1: Punch the center hole on the piston blank, and perform the outer circle processing on the piston blank after the center hole is punched;

[0039] S5: Apply a coating liquid on the outer circumference of the piston to form a coating;

[0040] S6: Apply the coating solution in the R angle of the piston to form a coating.

Embodiment 2

[0044] On the basis of embodiment 1, in this embodiment, step S2 is also included between said step S1 and said step S5: milling R and rough grinding of the outer circle of the piston after turning the outer circle in turn; R means that the R angle is processed by milling at the corresponding position of the piston; the rough grinding outer circle treatment refers to grinding the piston to improve the accuracy of the piston size, thereby improving the qualified rate of the product. During the processing, the piston is further polished through the above process to further ensure the quality of the piston processing.

[0045] The above specific process of milling the R angle is as follows: using a suitable milling cutter to process the piston to process the corresponding R angle.

[0046] Based on the above method, the specific steps of piston processing in the present embodiment are as follows:

[0047] S1: Punch the center hole on the piston blank, and perform the outer circl...

Embodiment 3

[0054] On the basis of the above implementation methods, in this embodiment, a step S3 is further included between the step S1 and the step S5: sandblasting the piston. During the processing, the bonding force between the coating and the piston can be enhanced through the above-mentioned process, so as to prevent the coating from bubbling, prevent the coating from falling off, and ensure the quality of coating processing.

[0055] The above-mentioned sand blasting process refers to the process of cleaning and roughening the surface of the piston by the impact of high-speed sand flow. Compressed air is used as the power to form a high-speed jet beam to spray the spray material (copper ore, quartz sand, corundum, iron sand, Hainan sand) to the surface of the piston to be treated at a high speed, so that the appearance or shape of the outer surface of the piston surface changes. , due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of t...

Abstract

The invention relates to a production process of a smearing type automobile air conditioner compressor piston. The production process comprises the following specific steps that a center hole is punched in a piston blank, and turning the outer circle of the piston blank punched with the center hole;r milling and outer circle rough grinding treatment are sequentially conducted on the piston subjected to outer circle turning; the piston is subjected to sand blasting treatment; the piston subjected to sand blasting is cleaned, cleaned and dried; coating liquid is smeared on the outer circumference of the piston to form a coating; the coating liquid is smeared in the R angle of the piston to form the coating; the piston is preheated and dried; the dried piston is subjected to accurate grinding treatment; redundant parts at the two ends of the dried piston are cut off; ball socket milling treatment is conducted on the piston; and the piston obtained after ball socket milling is cleaned and dried. The production process of the smearing type automobile air conditioner compressor piston has the beneficial effects that a coating process is adopted, so that the coating quality of the coating can be ensured, the binding force and the wear resistance of the coating are effectively improved, the coating liquid can be saved, the cost is saved, and the production process of the smearing type automobile air conditioner compressor piston is environment-friendly.

Description

technical field [0001] The invention relates to the technical field of piston processing technology, in particular to a production technology of a wiper-type automobile air-conditioning compressor piston. Background technique [0002] The automobile air-conditioning compressor compresses gas through the reciprocating movement of the piston in the cylinder, and good airtightness is required between the piston and the cylinder wall. The traditional technology is realized by fixing the piston ring on the piston body. However, when the compressor is working, the friction between the piston and the cylinder wall of the cylinder will generate heat, which will easily deform the piston ring, resulting in poor airtightness and increased friction. , which affects the working efficiency and service life of the air conditioning compressor. [0003] In order to solve the above problems, the traditional technology usually sprays a layer of coating on the surface of the piston, but this m...
