Embodiment Construction

[0025] A process for machining a rack by using a numerical control macro program includes:

[0026] Utilize CAD software to make drawings, take the workpiece coordinate system during processing as the benchmark, and convert the machining contour into a functional equation based on the technical parameters in the rack drawing; if the processed rack needs to be ground, the margin can be reserved through parameter setting;

[0027] Import functional processing trajectory in G code;

[0028] The law of the rack itself and its contour line can be obtained by the rack calculation company and the conversion of the right triangle. The function equation is as follows:

[0029] Tooth pitch formula: X=πm

[0030] Straight tooth length calculation formula: Y1=R6*R5

[0031] The Z-axis lower tool position determines the Y distance: (200-2.25m)²+Y²=200²

[0032] Helical tooth length calculation formula: Y=R6*R5 / COS(R4)

[0033] Calculation of helical gear Y-axis direction: Y3=R0*π*m*TA...

Abstract

The invention discloses a method using a numerical control macroprogram to process a tooth bar; the method comprises the following steps: using a parameterization window to input tooth bar parameters into a numerical control system according to working drawing size technical parameters; converting a processing shape contour into a function equation according to the technical parameters in the drawing; inputting parameters so as to reserve processing balance according to actual needs. The method can realize power off reprocessing, can precisely associate the numerical control macroprogram with space analytical geometry, calculus, logic algebra, CAD / CAM, computer programming, machinery processing and numerical control system subjects, and can continuously process in the original spot, thus improving efficiency and accuracy, reducing operator requirements, and realizing a unified processing program of straight teeth and helical teeth with different modulus, lengths, heights and widths; the method can automatically invoke subprograms according to drawing tooth bar technical parameters.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of mechanical processing, in particular to a processing method for a rack, in particular to a process for processing a rack by using a numerical control macro program. [0003] Background technique: [0004] Rack and pinion, large bearing capacity, high transmission accuracy, up to 0.1mm, can be docked for unlimited length, transmission speed can be very high, >2m / s, disadvantages: if the processing and installation accuracy is poor, the transmission noise is large, and the wear is large.
