Abstract
The invention discloses a numerical control system of a generating gear grinding machine. The numerical control system comprises a PLC (programmable logic controller), a touch screen, a servo motor and a working table. The touch screen is connected with the PLC, the PLC controls the servo motor to move, generating relative movement of the working table and a workpiece is driven by the servo motor, and grinding to involute gears is achieved. The numerical control system has the advantages that a basic disk and a differential motion change gear can be canceled, the servo motor drives a lead screw to be in a direct transmission, and generating movement is completed through program linear interpolation. Tooth profile amendment can be achieved by modifying parameters. Transmission steps are reduced, the numerical control system is free of mechanical abrasion and high in precision. Different workpieces can be replaced only by inputting the parameters like tooth number and mode number and the like. The numerical control system requires no other accessories, processing precision is improved, maintenance rate and maintenance cost are greatly lowered, and the numerical control system has no technical requirements of an operator.
Description
technical field [0001] The invention relates to the technical field of automatic machinery, in particular to a numerical control system for a gear grinding machine with a generating method. Background technique [0002] When the traditional generating method gear grinding machine grinds the involute gear, it adopts rolling disc rolling (such as Y7132 series gear grinding machine) or hanging wheel differential (such as Y7131.Y7150 series gear grinding machine) to achieve Generated motion of workpiece and table. The operation is cumbersome, and the hanging wheel is easy to lose accuracy due to wear and tear. The cycle is long and the adjustment is cumbersome when replacing different workpieces; the processing cost of accessories is high; there are technical requirements for the operator. Contents of the invention [0003] In order to solve the above problems, the present invention provides a numerical control system of a generating method gear grinding machine. [0004] T...
