Abstract

The invention relates to a numerical control machining method of a brake head. The numerical control machining method is characterized by comprising the following steps that a), a numerical control machining program of the brake head is input into a storage unit of a machine tool; b), X, Y and Z coordinates values of a machining original point in a workpiece coordinate system of the machine tool are set; c), according to a), the workpiece is machined into the brake head through the numerical control machining program in the middle, and then the contour deviation position and the deviation sizecaused by deformation in the machining process of the brake head are determined; and d), according to the machining track and the c), the contour deviation of the brake head in the reverse directionis corrected. According to the numerical control machining method, machining parameters are controllable, the stability is good, the machining track can be accurately adjusted, accurate control on themachining process can be easily realized, and the method is high in flexibility and wide in application range.

Description

technical field

[0001] The invention relates to the field of numerical control machining of parts, in particular to a numerical control machining method of a brake shoe holder. Background technique

[0002] The brake shoe holder is the brake actuator component of the rail vehicle in rail transit, and it is one of the parts with the most complicated working conditions. Among them, the double brake shoe support is designed to adapt to the complex working environment in mountainous areas and ensure the safety effect of braking, and the double brake shoe support can be installed with two brake shoes at the same time to ensure double braking deceleration torque when braking. The functional design determines that the structural size of the brake shoe holder is twice as large as that of the ordinary brake shoe holder, which increases the processing difficulty of the part. Due to the increase of the length dimension of the brake shoe holder, the machining deformation of the workpie...
