Embodiment Construction

[0015] like figure 1 Shown, the processing technology of vacuum pump housing of the present invention, comprises the steps:

[0016] Step 1. Check the blank of the vacuum pump shell. It is required that the appearance has no burrs, no casting defects, and the surface gloss is uniform. If there are defects on the surface of the shell, the diameter of the defect must be less than 2mm, the depth must be less than 1mm, and the entire shell should not exceed 2mm. If it does not meet the requirements, it is judged that the blank is an unqualified blank;

[0017] Step 2. Check the painting tools, adjust the paint, and make the painted surface uniform, that is, the ratio of paint to curing agent is 3:1, and the ratio of paint to thinner is 10:1. Adjust the spraying pressure to 7~8KG, place the oven at 120~140°C after painting, and set the drying time for 30 minutes. Prevent the corrosion of the vacuum pump casing during processing and play a role in processing protection;

Abstract

The invention provides a machining process of a vacuum pump case and belongs to the field of machining. The machining process of the vacuum pump case provided by the invention comprises the steps of blank inspection, surface painting, rough turning, (extraction opening and oil filling hole machining and fine turning) oil filling hole and extraction end machining through a four-station machine tool; eight-station machining, fine turning of all remaining sizes, size measurement and verification and cleaning. The machining process can provide a standard basis for vacuum pump case machining, the machining accuracy of the vacuum pump case is improved, the acceleration transition is enabled to be smoother and the service life of the vacuum pump is prolonged.

Description

technical field [0001] The invention relates to a processing technology of a vacuum pump, in particular to a processing technology of a vacuum pump housing. Background technique [0002] The vacuum pump is a reliable braking power source for the automobile brake booster system. The contour of the vacuum pump cavity has very strict requirements on the acceleration and deceleration of the blades, the friction between the blades and the contour, power consumption, NVH vibration and noise, etc. Require. Therefore, the contour design of the inner cavity is very important. The unique contour parameters of the vacuum pump obtained through optimal design can optimize the following performance: make the acceleration transition smoother; reduce engine power consumption; reduce vibration and noise; reduce wear between parts ; Extend the service life of the vacuum pump. [0003] However, the vacuum pump processing industry is currently in the development stage, and there is no complet...
