Problems solved by technology

[0005] During the gear hobbing process of the above-mentioned existing gear hobbing machine, the cutting fluid will be continuously sprayed between the hob and the gear base through a pipe, but the cutting fluid sprayed between the contact points of the two is easy to rotate with the high-speed rotation of the hob. If it is thrown out of the machine table and cannot fall vertically on the platform at the bottom, it will not only cause a lot of waste of cutting fluid and increase the cost of gear hobbing, but also easily cause a lot of oil pollution on the ground around the workbench, and the working environment for employees is poor and damage operator health

Embodiment 1

[0040] A gear pulse type cutting device in a drive axle, refer to figure 2 , including a machine 1, the machine 1 is provided with a hob 2 and a chuck 3 whose axes are perpendicular to each other, the gear base 4 to be cut is clamped in the chuck 3 through an integrally formed shaft 8, and the machine 1 and A cutting fluid recovery tank 7 is arranged at the bottom of the hob 2 . During the cutting process, the hob 2 rotates at a high speed, while the gear base 4 rotates slowly under the drive of the chuck 3 and moves horizontally toward the hob 2, so that the two contact and roll out of the tooth hole.

[0041]The cutting device also includes a three-way pipe 5 , and the three-way pipe 5 includes a liquid feed pipe 501 , a gas feed pipe 502 and a pulse discharge pipe 503 that communicate with each other. During the cutting process, the liquid feed pipe 501 is used to deliver the cutting fluid to the pulse discharge pipe 503; one end of the gas feed pipe 502 communicates with...

Embodiment 2

[0050] A gear pulse cutting process in the drive axle, the difference from Embodiment 1 is: the time for each cutting fluid to be ejected from the pulse discharge pipe 503 is set to 100ms; each time the compressed air is ejected from the pulse The ejection time of the discharge pipe 503 is all set to be 60ms.

Embodiment 3

[0052] A kind of gear pulse type cutting device in drive axle, refer to figure 2 , including a machine 1, the machine 1 is provided with a hob 2 and a chuck 3 whose axes are perpendicular to each other, the gear base 4 to be cut is clamped in the chuck 3 through an integrally formed shaft 8, and the machine 1 and A cutting fluid recovery tank 7 is arranged at the bottom of the hob 2 . During the cutting process, the hob 2 rotates at a high speed, while the gear base 4 rotates slowly under the drive of the chuck 3 and moves horizontally toward the hob 2, so that the two contact and roll out of the tooth hole.

[0053] The cutting device also includes a three-way pipe 5 , and the three-way pipe 5 includes a liquid feed pipe 501 , a gas feed pipe 502 and a pulse discharge pipe 503 that communicate with each other. During the cutting process, the liquid feed pipe 501 is used to deliver the cutting fluid to the pulse discharge pipe 503; one end of the gas feed pipe 502 communicat...

Abstract

The invention discloses a gear pulse type cutting device in a drive axle and a cutting process thereof, and relates to the technical field of drive axle part machining. According to the technical key point, the gear pulse type cutting device in the drive axle comprises a machine table; a hob and a chuck are arranged on the machine table, wherein the axes of the hob and the chuck are perpendicular to each other; a gear base body to be cut is fixed to the chuck; the gear pulse type cutting device in the drive axle further comprises a three-way pipe; the three-way pipe comprises a liquid feeding pipe, a gas feeding pipe and a pulse discharging pipe; pulse valves are arranged on the liquid feeding pipe and the gas feeding pipe; and the pulse valves are controlled to be opened and closed through the PLC. The pulse discharging pipe is located on the side where a cutting fluid is thrown out of the hob; the outlet direction of the pulse discharging pipe faces the contact point of the gear base body and the hob; the pulse discharging pipe is obliquely arranged; and the lower end of the pulse discharging pipe is close to the contact point of the gear base body and the hob. The gear pulse type cutting device in the drive axle has the advantages that waste of the cutting fluid is reduced, gear hobbing cost is reduced, a good working environment is guaranteed, and the influence of the working environment on health of operators is reduced.

Description

technical field [0001] The invention relates to the technical field of drive axle parts processing, more specifically, it relates to a gear pulse cutting device in the drive axle and its cutting process. Background technique [0002] The drive axle is a mechanism located at the end of the drive train that can change the speed and torque from the transmission and transmit them to the drive wheels. The drive axle is generally composed of a final drive, a differential, a wheel drive, and a drive axle housing, while the final drive, differential, and wheel drive are mainly composed of gears that mesh with each other at all levels. [0003] The existing gears are hobbed by a gear hobbing machine. The hobbing principle of the gear hobbing machine is as follows: figure 1 As shown, it includes a hob 2 and a chuck 3 arranged on a machine 1, and the machine 1 is provided with a cutting fluid recovery tank 7 for recovering cutting fluid at the bottom of the hob 2 and the chuck 3 . Du...
