Detailed Description
As shown in fig. 1 to 4, a brake locking mechanism of a ring-cone of a numerical control turntable is a numerical control turntable formed by meshing a worm wheel 6 and a worm 7, wherein the worm 7 is connected with an external power part, the lower surface of the worm wheel 6 is connected with a brake disc 4 through a fastening screw 2, and the outer circumference of the brake disc 4 is of an annular cone structure; the bottom of the numerical control turntable is a turntable box body 3, two oil cylinders 1 are arranged on the turntable box body 3, the two oil cylinders 1 are symmetrically distributed on two sides of a brake disc 4, an arc-shaped double-conical-surface V-shaped block 5 is connected to a piston of each oil cylinder, a V-shaped opening is arranged on each arc-shaped double-conical-surface V-shaped block 5, and the V-shaped openings are in contact fit with an annular conical surface structure of the brake disc 4.
The upper part of the brake disc 4 is of a flange structure, the center of the brake disc is provided with a groove structure, and the groove provides a connecting space for components such as an encoder and the like.
The application discloses numerical control revolving stage ring conical surface brake locking mechanism's theory of operation is:
after the worm wheel 6 and the worm 7 of the numerical control turntable are meshed to drive the brake disc 4 to stop rotating, the left side oil cylinder pushes the left side arc double-conical-surface V-shaped block 5 to move rightwards, meanwhile, the right side oil cylinder pushes the right side arc double-conical-surface V-shaped block 5 to move leftwards synchronously, and the left side arc double-conical-surface V-shaped block 5 and the right side arc double-conical-surface V-shaped block 5 act on the annular conical surface of the annular conical-surface brake disc 4 synchronously to play a role in braking and locking. When the brake is unlocked and braked, the oil cylinder moves reversely, and the V-shaped block 5 is separated from the annular conical surface of the brake disc 4.
Experiments prove that the brake locking mechanism has the advantages of simple and compact structure, low cost, reliable performance and convenience in installation. The numerical control turntable has important functions of improving the reliability of the brake locking of the numerical control turntable, the rapidity of indexing and positioning and improving the comprehensive performance of the numerical control turntable.
