Automatic backlash driving and indexing worktable for gear grinding machine

Abstract

The invention relates to an automatic backlash driving and indexing worktable for a gear grinding machine. According to the automatic backlash driving and indexing worktable, the defects that the indexing of a traditional worktable is finished by adopting a pure mechanical driving chain with a complex structure, the structure is relatively complex and the indexing precision is lower are overcome. A worm gear and two worms which are mutually meshed are arranged in a casing; the two worms are mutually parallel; a plane where two worms are positioned is parallel to an axial line of the worm gear; two groups of worm teeth which are respectively meshed with two worms are arranged on the circumference of the worm gear; the two worms comprise a driving worm and a driven worm; the driving worm is connected with the motor; same straight gears are fixed at the same ends of the driving worm and the driven worm; a same idle gear is meshed between the two straight gears; and a hydraulic oil cylinder is connected to the other end of the driven worm. The driven worm is elastically ejected by the hydraulic oil cylinder, the meshed clearance between the worms and the worm gear can be adjusted and the high-precision indexing of the worktable is realized.

Description

technical field [0001] The invention relates to an indexing workbench of a gear grinding machine, in particular to an automatic backlash elimination driving indexing workbench of a gear grinding machine with an automatic backlash elimination function. Background technique [0002] The mechanical equipment industry is a country's strategic industry. The components of many industries are processed by various mechanical equipment. The higher the level of the mechanical equipment industry, the higher the precision of the processed components. Therefore, it is highly regarded by various countries. Pay attention to. [0003] With the rapid development of my country's automobile industry, shipbuilding industry and new energy such as wind power equipment industry, various gears will be used in these industries, and the precision requirements for these gears are getting higher and higher, while reducing processing energy consumption, Reducing processing difficulty has also become a d...

Problems solved by technology

[0006] The invention solves the defects that the traditional workbench indexing is completed by using a purely mechanical transmission chain with a complex structure, the structure is relatively complicated, and the accuracy of the indexing is relatively low, and it provides an automatic backlash-eliminating drive indexing workbench for gear grinding machines , using worm gear transmission to complete the indexing, the structure is simple, and the accuracy of the indexing is also high

[0007] The present invention also solves the defects in the prior art that the double worms are connected by bevel gears, resulting in increased processing difficulty and increased assembly difficulty, and provides an automatic backlash-eliminating driving indexing workbench for gear grinding machines. The two worms are connected parallel to each other by spur gears. Reduced processing difficulty and reduced assembly difficulty

[0008] The invention also solves the defect that the bevel gear is used to connect the two worms in the prior art, and the axial force generated by the bevel gear will affect the gap adjustment between the worm and the turbine, and provides an automatic backlash-eliminating driving indexing work for the gear grinding machine The platform uses a spur gear to connect the two worms, which will not affect the gap adjustment between the worm and the turbine
