Problems solved by technology

[0003] 1. The existing manufacturing methods of automobile gearbox gears are simple, the quality of the produced products is average, and the general service life is not long;
[0004] 2. At present, most automotive gearbox gear blanks are turned by ordinary lathes, and all turning processes cannot be completed in one clamping, and it is difficult to ensure the coaxiality of the inner hole and the side surface, as well as the verticality of the end surface and the hole axis;
[0005] 3. Most of the existing gears of automobile transmission gears are hobbed by ordinary hobbing machines, the machining accuracy is low, and the surface

Abstract

The invention relates to the technical field of gear machining, in particular to a fixing slotting device for a vehicle transmission gear. The fixing slotting device comprises a base, the gear, U-shaped frames and a support. The two U-shaped frames are arranged at the upper end of the base, the gear is directly arranged on the U-shaped frames, the support is arranged on the side face of the base, a drooping rod is arranged at the top end of the support, and a tertiary slot knife, a secondary slot knife and a primary slot knife are arranged at the lower end of the drooping rod. According to the fixing slotting device, the U-shaped frames are adopted for clamping the gear; and meanwhile the gear can be slotted in place at a time through the joint action of the tertiary slot knife, the secondary slot knife and the primary slot knife, dimensional uniformity is guaranteed, the yield is increased, and the fixing slotting device has the beneficial effects of being convenient to use, easy to operate, high in practicality, low in cost and the like.

Description

technical field [0001] The invention relates to the technical field of gear processing, in particular to a fixed slotting device for an automobile transmission gear. Background technique [0002] Generally, gears with variable speed are collectively referred to as transmission gears. The commonly used material for transmission gears is forged steel. Transmission gears often work under conditions of high speed, high load, and constant alternation of speed and load. The speed change gears rely on their own structural dimensions. And the strength of the material to bear the external load, which requires the material to have high strength, toughness and wear resistance. Due to the complex shape of the transmission gear, high gear precision requirements, and good material method, the current manufacturing method of automobile transmission gears has the following technical problems: [0003] 1. The existing manufacturing methods of automobile gearbox gears are simple, the quality...
