Gear hobbing device used for processing part of gearbox

Abstract

The invention discloses a gear hobbing device used for processing a part of a gearbox. The gear hobbing device comprises a fixed plate, a mounting block, a mounting plate, an adjusting motor, a fixedrod, stop blocks, a disk, a bottom plate, a gear hobbing machine, supporting legs, a drive motor, a fixed column, a threaded rod, a sliding block, a connecting rod, an annular plate, a lug, limit springs, telescopic springs, telescopic rods, limit plates, sliding rods, baffles, a connecting plate, connecting springs and arc-shaped blocks; the supporting legs are correspondingly fixed to the four corners of the bottom part of the fixed plate; the top part of the fixed plate is fixedly provided with the mounting block; a groove is formed in the top part of the fixed plate; and the disk is arranged in the groove. According to the gear hobbing device, with the cooperation of the threaded rod and the sliding block, the connecting rod and the fixed rod are driven to move down, so that the fixedrod and the stop blocks interact with each other to push the stop blocks to the two sides so as to avoid that the gear hobbing machine is influenced by the stop blocks during operation, and thereby, time consumed by adjustment is shortened, and the efficiency of processing the part is increased.

Description

technical field [0001] The invention relates to a gear hobbing device, in particular to a gear hobbing device used for processing gearbox parts, and belongs to the technical field of parts processing applications. Background technique [0002] The gearbox mainly refers to the gearbox of the car, which is divided into manual and automatic. The manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; It is composed of torque converter, planetary gear, hydraulic pitch change system and hydraulic control system. To achieve variable speed and torque through the combination of hydraulic transmission and gears, many parts need to be processed in the production of gearboxes. [0003] The existing patent publication number is CN209050211U, a special gear shaft hobbing device. When the special gear shaft hobbing device is working, the angle of the cutter can be adjusted according to the processing need...

Problems solved by technology

[0004] The purpose of the present invention is to solve the existing problem that the push rod motor is used to push the push block to move, thereby pushing the entire disc to rotate. The push block can be restored to the position before the first push, and the operation is repeated to solve the problem that it is difficult to accurately and quickly load the parts in the prior art. The mutual engagement of the threaded rod and the slider makes the connecting rod and the fixed rod move toward each other. Moving down, the fixed rod pushes the limit block to move towards both sides of the connecting rod, and the work of the adjustment motor drives the connecting rod and the parts to rotate, and under the action of the gear hobbing machine, the parts are processed to solve the problem that it is difficult to process the parts in the prior art Quickly fixed the problem
