Problems solved by technology

The disadvantage is that the equipment for local anodizing is expensive (equipment has a patent), and the electrolyte is also a special formula (equipment manufacturer's formula)
And the cost of the second method is higher than the cost of the first method

Embodiment Construction

[0026] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0027] A method for processing an ABS / ESC valve body for an automobile braking system, characterized by comprising the following steps:

[0028] a) Select the machined surface and hole of the valve body as the rough positioning reference for machining after oxidation, and reserve the machining allowance; the rough positioning reference hole 1 and the rough positioning reference surface 2, such as figure 1 shown;

[0029] b) Machining the rough positioning reference hole and rough positioning reference surface of the valve body and the accumulator hole on the valve body; such as figure 1 , figure 2 shown;

[0030] c) Carry out the overall hard anodizing process for the valve body after the second step processing;

[0031] d) Based on the rough positioning reference hole and rough positioning reference surface on the valve body, machine t...

Abstract

The invention discloses an ABS/ESC valve body machining method for an automobile braking system. The ABS/ESC valve body machining method is characterized by comprising the following steps that firstly, a valve body machined face and hole are selected as a machining rough positioning datum after oxidation, and the machining allowance is reserved; b, a rough positioning datum hole and a rough positioning datum face of a valve body and an energy accumulator hole in the valve body are machined; c, integral sulfuric acid hard oxidation is conducted on the valve body obtained after machining in thesecond step; and d, the rough positioning datum hole and the rough positioning datum face on the valve body serve as the datum, the rest of holes of the valve body obtained after oxidation in the third step are machined, and the rough positioning datum hole and the rough positioning datum face are machined to the size through datum conversion. According to the ABS/ESC valve body machining method,the anode oxidation surface area is small, only the surface of the energy accumulator hole of the valve body is provided with an oxidation film through machining finally, and the later procedure assembling and functions of the ABS/ESC valve body cannot be influenced.

Description

technical field [0001] The invention belongs to the technical field of valve body technology, and in particular relates to a processing method for an ABS / ESC valve body used in an automobile braking system. Background technique [0002] At present, the valve body of the ABS / ESC of the braking system of a passenger car is made of aluminum alloy, and the accumulator hole of the valve body is the place where the piston moves. In order to increase the wear resistance of the accumulator surface, anodizing is generally required. At present, there are two main methods for oxidizing the surface of the accumulator hole: [0003] (1) The first method: After the machining of the entire valve body is completed, anodize the entire valve body. The disadvantage is that due to the completion of the valve body processing, the surface area is increased, the overall anodizing cost is high, and at the same time, it affects the ABS / ESC valve body assembly and the performance of the braking syst...
