Abstract
The utility model discloses a brake mechanism of a numerical control turntable, which includes a brake cylinder body and a drive shaft, wherein the front end of the drive shaft is mounted in the brake cylinder body; a brake pad is mounted at the front end of the drive shaft through a shaft sleeve; a piston is mounted in the brake cylinder body; an air inlet is arranged on the brake cylinder body; and the brake pad and the piston are mounted oppositely. According to the utility model, the brake part is advanced onto a worm, so that the service life of the brake mechanism of the turntable is prolonged, the energy consumption is lowered, and the cost is reduced.
Description
Technical field
The utility model relates to a kind of numerical control rotating platform braking mechanism.
Background technique
If the velocity ratio of general NC turntable worm and gear is 1:60; With regard to the moment of torsion that is equivalent to worm gear is stopped is to make 60 times of moment of torsion that worm screw stops; Common worm and gear is because there is drive gap; Therefore in order to guarantee the precision of braking, general NC turntable braking mechanism just must brake at the turntable worm-wheel shaft.
This kind mode is not only wasted energy consumption, and brake part manufacture cost is higher.
The model utility content
The utility model technical issues that need to address just are to overcome the defective of existing technology, and a kind of numerical control rotating platform braking mechanism is provided, and it makes to brake partly to advance on the worm screw carries out, and has improved the life-span of turntable braking mechanism, lowers energy consumption, reduces cost.
For addressing the above problem, the utility model adopts following technological scheme:
The utility model provides a kind of numerical control rotating platform braking mechanism; Comprise brake cylinder body and live axle; Said live axle front end is installed in the brake cylinder body, and said live axle front end is equipped with brake block through axle sleeve, in the said brake cylinder body piston is installed; The brake cylinder body is provided with inlet hole, and said brake block and piston are installed relatively.
Said brake cylinder body is provided with a locating stud.
Said numerical control rotating platform is a no gap numerical control rotating platform; Comprise the worm gear and the worm screw that cooperatively interact, said live axle is the screw shaped worm screw, and said worm gear is the turret structure that the driven bearing of needle roller is radial embedding; Worm gear contacts with worm screw through the driven bearing of needle roller, is the contact of no gap between the worm and gear.
The utility model utilization does not have the gap numerical control rotating platform, because very close to each other between worm and gear, make the brake part can advance on the worm screw and carries out, use tens of common turntable/once moment of torsion can accomplish brake (determining) by velocity ratio.In the bigger turntable of table top more than 250, also only just can realize brake, thereby save the cost that uses the pressurized oil system brake and cut down the consumption of energy with 0.6MPa air pressure device.
The working principle of the utility model is:
Got into by inlet hole and to promote piston behind the pressure air and move ahead, compress brake block, brake block is fixed on the axle sleeve and with live axle (worm shaft) and is fixed together, the realization brake function.
The utility model has improved the life-span of turntable braking mechanism, lowers energy consumption, reduces cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the said no gap of a utility model numerical control rotating platform structural representation.
Embodiment
As shown in Figure 1; The utility model provides a kind of numerical control rotating platform braking mechanism, comprises brake cylinder body 1 and live axle 2, and said live axle front end is installed in the brake cylinder body; Said live axle front end is equipped with brake block 4 through axle sleeve 3; In the said brake cylinder body piston 5 is installed, the brake cylinder body is provided with inlet hole 6, and said brake block and piston are installed relatively.
Said brake cylinder body is provided with a locating stud 7.
As shown in Figure 2; Said numerical control rotating platform is a no gap numerical control rotating platform; Comprise the worm gear 8 and the worm screw that cooperatively interact, said live axle is the screw shaped worm screw, and said worm gear is the turret structure that the driven bearing 9 of needle roller is radial embedding; Worm gear contacts with worm screw through the driven bearing of needle roller, is the contact of no gap between the worm and gear.
The utility model utilization does not have the gap numerical control rotating platform, because very close to each other between worm and gear, make the brake part can advance on the worm screw and carries out, use tens of common turntable/once moment of torsion can accomplish brake (determining) by velocity ratio.In the bigger turntable of table top more than 250, also only just can realize brake, thereby save the cost that uses the pressurized oil system brake and cut down the consumption of energy with 0.6MPa air pressure device.
The working principle of the utility model is:
Got into by inlet hole and to promote piston behind the pressure air and move ahead, compress brake block, brake block is fixed on the axle sleeve and with live axle (worm shaft) and is fixed together, the realization brake function.
The utility model has improved the life-span of turntable braking mechanism, lowers energy consumption, reduces cost.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to mode of execution.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all mode of executions.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
