Embodiment Construction

[0023] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0024] see figure 1 and figure 2 , a brake shoe biaxial device processing technology, the processing steps are:

[0025] The first step is to make the overall steel casting: reasonably set the distance between the support frame and the shaft head and the distance between the shaft head and the shaft head. In the sand mold of the shoe biaxial device, the casting of the brake shoe biaxial device is made; the casting is made of resin sand and shot sand molding, the casting has good rigidity and smooth appearance, and after annealing treatment, the performance is stable and does not deform; the body cast steel part The strength of the structure is high.

[0026] The second step is the surface of the shaft head 1 on the casting of the dual-axis device of the brake shoe: use a numerical control lathe, coordinate with the special fixture for positioning, first proces...

Abstract

The invention relates to a processing technology of brake shoe double-shaft device, which is characterized in that distance between a bearing bracket and a shaft head and between the shaft head and the shaft head is reasonably set, a brake shoe double-shaft device integral steel casting is adopted, then a front and a rear surfaces of the shaft head are respectively turned, then a space ring positioning, boring and tapping are milled, and finally inspection and electrophoretic paint treatment are undertaken to prepare a brake shoe double-shaft device finished product. The processing technology has the advantages of simple production process, low production cost, good product quality, strong braking performance, high product precision and high safety performance.

Description

【Technical field】 [0001] The invention belongs to the technical field of vehicle accessories manufacturing industry, and relates to a processing technology of a brake shoe biaxial device of a vehicle brake system. 【Background technique】 [0002] The brake shoe biaxial support device is an important component for supporting the brake shoe, and plays a very critical role in the braking performance of the whole vehicle. The existing brake shoe biaxial support device is composed of a brake shoe biaxial support frame and two shafts, and the two parts are welded by frocks. [0003] The processing steps of the existing brake shoe biaxial support frame are: steel casting → milling one side surface of the steel casting → machining hole on one side of the steel casting → machining hole on the other side of the steel casting → Milling the other side of the cast steel surface → chamfering acute angles → drilling welding holes; [0004] The processing steps of the shaft are: round stee...
