Embodiment Construction

[0045] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0046] A brake disc processing tool, such as Figure 1 to Figure 13 As shown, the brake disc 7 is a disc-shaped part with a boss, and the center of the brake disc 7 is provided with a central hole. One side protruding from the boss is a convex surface, which is the wheel mounting surface C, and the other side is a concave surface, which is the hub mounting surface B. , the axis of the center hole is the datum A. The brake disc 7 is positioned with the convex surface of the boss, three positioning blocks 8 are arranged below the convex surface, the positioning blocks 8 are against the pre-processed positioning edge at the edge of the convex surface, and three clamping claws 9 are arranged on the outer surface of the boss. In order to ensure the positioning accuracy, after the positioning surfaces of the three positioning blocks are processed, they are fina...

Abstract

A brake disc machining knife comprises a knife rod, a transition hook and a knife body. The knife rod is of a structure of a round rod, three vertical clamping faces in clamp fit with the knife rod machined on a cylindrical face of the round rod, the transition hook comprises a connecting disc, a side column and an underframe which are integrally machined, the connecting disc is coaxially fixed at the lower end of the knife rod, the side column is smoothly connected at the outer edge of the connecting disc and extends downward, the underframe is connected at the lower end of the side column and is a cylinder coaxial with the connecting disc and provided with a knife body mounting groove, the knife body comprises a radial knife radially mounted on the underframe, and a knife tip of the radial knife is positioned on one side opposite to the side column and points above. By using the brake disc machining knife, a measuring reference and a measuring plane are machined in a same process according to a same machining reference, machining accuracy is improved, and errors caused by repeated clamping during machining in different processes are avoided.

Description

technical field [0001] The invention relates to a processing tool and a processing method thereof, in particular to a tool suitable for processing the end face of a brake disc and a processing method thereof. Background technique [0002] The brake disc plays a vital role in the braking system of the car. A brake disc with excellent performance is one of the prerequisites for the safe driving of the car. Therefore, the shape and position tolerance of the brake disc is strictly required in the design. The difficulty also increases accordingly. [0003] See attached figure 1 , The brake disc is a disc-shaped part with a boss and a central hole, with a thinner thickness. The convex side is the wheel mounting surface C, and the concave side is the hub mounting surface B. For a brake disc, the circumferential thickness difference between the wheel mounting surface C and the hub mounting surface B is required to be 0.015mm; the runout of the wheel mounting surface is required to...
