Numerical control generating gear grinding machine and numerical control device thereof and driving method

Abstract

The invention discloses a numerical control generating gear grinding machine, a numerical control device of the generating gear grinding machine and a driving method of the generating gear grinding machine. In the invention, the numerical control device respectively controls a motor to drive a sliding block of a work bench to make rectilinear motion and drive the work bench to make reciprocating circumferential swing, that the motor drives the work bench to make reciprocating circumferential swing by virtue of a multistage mechanical drive mechanism is not needed, thus no mechanical drive error caused by the processing precision and installation precision of the drive part exists in the generating motion of a gear to be processed driven by the sliding block of the work bench and the work bench, and the processing precision of the generating gear grinding machine is further improved; by replacing a great number of mechanical drive mechanisms with the motor, the fault probability of the generating gear grinding machine is greatly reduced.

Description

technical field [0001] The invention relates to numerical control machining technology, in particular to a numerical control generating gear grinding machine, a numerical control device of the generating gear grinding machine and a driving method of the generating gear grinding machine. Background technique [0002] After the gear is rough-machined, such as hobbing and milling, it often needs to be finished according to the actual application of the gear. [0003] The finishing of the gear can be achieved by grinding with a gear grinding machine. According to the principle of grinding, gear grinding machines can be roughly divided into two types: forming gear grinding machines and generating gear grinding machines. The forming gear grinding machine uses a grinding wheel whose shape line is similar to the gear shape line to grind the gear, while the forming gear grinding machine drives the gear to rotate and drives the gear to move in a straight line, that is, drives the gea...

Problems solved by technology

However, if there is an error in calculation or installation, it will further cause the trajectory of the generated motion to deviate from the involute of the gear to be processed, which will seriously affect the tooth profile accuracy level of the gear to be processed, and even damage the gear to be processed

And in the actual processing process, it may not be possible to obtain the transmission gear that meets the requirements in time due to the limited gear specifications, so that it is effectively impossible to grind all the gears to be processed

[0020] It can be seen that the machining accuracy of the existing generated gear grinding machines is low, and the reliability and versatility are not high
