Compound tool for processing oil cup seat in brake master cylinder

Abstract

The invention relates to a compound tool for processing an oil cup seat in a brake master cylinder. The compound tool comprises a cam shaft, a connecting disc and a protruding compound tool group, wherein the compound tool group and the cam shaft are separately arranged on two sides of the connecting disc; the compound tool group comprises a sheet body, a step hole milling cutter and an end surface milling cutter; the sheet body is radially fixed along the connecting disc, the step hole milling cutter is arranged on two side edges of the sheet body while the end surface milling cutter is fixed on the connecting disc and is connected to the step hole milling cutter to form a compound milling cutter structure of a primarily formed connecting body and the end surface. According to the compound tool provided by the invention, four cutters: the end surface milling cutter, a milling cutter with the diameter of 28mm, a milling cutter with the diameter of 27.5mm and a milling cutter with the diameter of 25.4mm for processing the oil cup seat in the original brake master cylinder are integrated to obtain a primarily processed and formed brake cylinder processing compound tool so as to further reduce the replacing step of the tool group, so that the compound tool has the advantages and beneficial effects of shortening the processing time, lowering the cost, being high in work efficiency, small in labor intensity and the like.

Description

technical field [0001] The invention relates to a composite cutting tool for processing an oil cup seat in a brake master cylinder, in particular to a composite cutter which combines four props used in the processing of an oil cup seat in a brake master cylinder into one. Background technique [0002] The brake system is a relatively important part of the car body. The brake cylinder, commonly known as the brake caliper, is the final component that produces the braking effect in the brake system. When the brake pedal is stepped on, the brake fluid is squeezed by the brake The master cylinder distributes the pressure to each brake cylinder through the brake fluid pipeline. Due to the incompressibility of the liquid, the brake cylinder pushes the brake pads to rub against the brake disc under the action of the brake fluid pressure to generate friction. Braking action. [0003] At present, there is a stepped hole on the oil cup seat in the brake master cylinder, and the proces...

AI Technical Summary

Problems solved by technology

[0003] At present, there is a stepped hole on the oil cup seat in the brake master cylinder, and the processing of the oil cup seat in the brake master cylinder requires a total of four milling cutters, a 28mm diameter milling cutter, a 27.5mm diameter milling cutter, and a 25.4mm diameter milling cutter The tool is used to process the oil cup seat in the brake master cylinder. The whole process needs to replace a variety of tools. The processing process is cumbersome, resulting in long processing time, high cost, low work efficiency and high labor intensity.
