Tool setting device and tool setting method for gear machining on large-sized press

Abstract

The invention relates to a tool setting device and a tool setting method in machining. In order to overcome the defects generated by traditional gear machining, the invention provides the tool setting device used for gear machining on a large-sized press. The tool setting device is characterized by comprising a horizontal shaft and a vertical connecting yoke, wherein the left end of the horizontal shaft is provided with a stud fixed to a T-shaped groove in a facing head disk of a gear hobbing machine; the right end of the horizontal shaft is vertically welded to the vertical connecting yoke; the lower part of the connecting yoke is provided with a mounting sleeve with a mounting hole; a tool setting shaft parallel with the horizontal shaft is arranged in the mounting hole in the mounting sleeve; the end part of the tool setting shaft is provided with a tool setting head. The tool setting method comprises the following steps: fixing the left end of the horizontal shaft of the tool setting device and the T-shaped groove in the facing head disk of the gear hobbing machine, and adjusting the axial position of the gear hobbing machine to enable center cutter teeth or tooth sockets of the gear hobbing machine to be aligned with the tool setting head. According to the device and the method, the technical problems that tooth profiles of the left tooth surface and the right tooth surface of a to-be-processed gear on the large-sized press are asymmetric, and the precision of the tooth surfaces are hard to guarantee are fundamentally solved.

Description

[0001] technical field [0002] The invention relates to a tool setting device and a tool setting method in mechanical processing, in particular to a tool setting device and a tool setting device used to facilitate the centering of hob teeth or tooth grooves and workpieces when a large press gear is processed on a gear hobbing machine Tool setting method. Background technique [0003] Nowadays, the development of the machinery manufacturing industry is changing with each passing day, which makes the demand for the technology and quantity of processing equipment continue to increase, and the processing of various gears is becoming more and more important. The performance of the press is directly related to the meshing accuracy of the gears in the beam body. The running accuracy of the meshing between the gears determines the quality, precision and service life of the press; For gear parts, it is particularly important whether the hob’s teeth or tooth grooves are centered wit...

AI Technical Summary

Problems solved by technology

Both of these two tool setting methods have large errors, which are likely to cause asymmetric tooth profile deviations on the left and right tooth surfaces of the processed gear, which will lead to changes in the tooth shape and affect the machining accuracy.
