Embodiment Construction

[0016] Such as figure 1 As shown, the present invention provides a numerical control turntable brake mechanism, including a brake cylinder 1 and a drive shaft 2, the front end of the drive shaft is installed in the brake cylinder, and the front end of the drive shaft is installed with a brake pad 4 through a bushing 3 , a piston 5 is installed in the brake cylinder, an air inlet 6 is arranged on the brake cylinder, and the brake pad and the piston are relatively installed.

[0017] A positioning pin 7 is arranged on the brake cylinder.

[0018] Such as figure 2 As shown, the numerically controlled turntable is a gapless numerically controlled turntable, including a worm gear 8 and a worm 2 that cooperate with each other, the drive shaft is a screw-shaped worm, and the worm gear is a turret structure in which needle roller driven bearings 9 are radially embedded. The turbine is in contact with the worm through the needle roller bearing, and there is no gap between the turbin...

Abstract

The invention discloses a numerical control rotary table brake mechanism which comprises a brake cylinder body and a drive shaft. The front end of the drive shaft is installed inside the brake cylinder body. A brake pad is installed at the front end of the drive shaft through a shaft sleeve. A piston is installed in the brake cylinder body. An air inlet hole is formed in the brake cylinder body. The brake pad and the piston are installed oppositely. The numerical control rotary table brake mechanism enables braking to be carried out on a worm in advance, prolongs the service life, reduces energy consumption and lowers cost.

Description

[0001] technical field [0002] The invention relates to a numerical control turntable brake mechanism. Background technique [0003] If the transmission ratio of the worm gear of the ordinary CNC turntable is 1:60, it is equivalent to 60 times the torque to stop the turbine is 60 times the torque to stop the worm. Because the ordinary worm gear has a transmission gap, in order to ensure the braking accuracy, the ordinary CNC The turntable brake mechanism must brake on the turntable turbine shaft. [0004] This kind of way not only wastes energy consumption, but also the manufacturing cost of the braking part is relatively high. Contents of the invention [0005] The technical problem to be solved in the present invention is to overcome the defects of the prior art and provide a numerical control turntable brake mechanism, which advances the braking part to the worm, improves the life of the turntable brake mechanism, reduces energy consumption, and reduces costs. [000...
