Description

Technical Field

[0001] The utility model relates to the technical field of brake spindles, in particular to a brake spindle capable of stable braking. Background Art

[0002] The brake disc of the braking spindle is usually installed at the tail of the spindle, and brakes the rotation of the spindle through friction. When the CNC lathe needs to stop the rotation of the spindle, the brake disc will press tightly on the spindle, consume the kinetic energy of the spindle through friction, and stop the spindle quickly. Braking the spindle can improve the machining accuracy and efficiency of the CNC lathe.

[0003] When the existing brake spindle is in use, the hydraulic brake utilizes the hydraulic pressure of the hydraulic cylinder to connect the hydraulic cylinder and the piston on the back through the oil pipe, so that the brake pads clamp the spindle to achieve the braking purpose, while the pneumatic brake is composed of a pneumatic cylinder, a piston, a friction plate and a pressure plate. When the pneumatic cylinder is activated, the piston moves outward to make the friction plate and the pressure plate contact and clamp the spindle to achieve braking. Due to excessive heat in the hydraulic brake, part of the brake fluid vaporizes and bubbles are formed in the pipeline, which seriously affects the hydraulic transmission, reduces the efficiency of the brake system, and even completely fails the pneumatic brake. However, the pneumatic brake has poor safety and may explode in severe cases. It is not easy to control accurately. There is impact, loud noise and instability during operation. The sealing requirements are higher than those of hydraulic brake and it is easy to leak. Utility Model Content

[0004] The utility model aims to provide a brake spindle capable of stable braking, so as to solve the problem that the brake spindles on the market currently have poor performance through pneumatic braking or hydraulic braking as mentioned in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a brake spindle capable of stable braking, comprising a brake spindle body and a brake disc, wherein the outer wall of one end of the brake spindle body is sleeved with a brake disc.

[0006] Preferably, a connecting bin is provided on one side of the brake disc, mounting plates are welded around the connecting bin, sliding grooves are provided at the front and rear ends of the connecting bin, clamping brake pads are penetrated through the interiors of the two groups of sliding grooves, and a connecting disc extending to the outside is provided inside the connecting bin.

[0007] Preferably, two groups of arc grooves are opened inside the connecting disk, connecting shafts are sleeved inside the two groups of arc grooves, and the other ends of the two groups of connecting shafts are respectively welded to the two groups of clamping brake pads, and a gear plate is welded on the outer wall of the connecting disk.

[0008] Preferably, a servo motor is installed at the bottom end of the connecting bin via bolts, an output end of the servo motor is connected to a support shaft via a coupling, and a gear is welded to the outer wall of the support shaft.

[0009] Preferably, a fixing disk is welded to the outer wall of the brake spindle body, a mounting bolt is provided on one side of the fixing disk, and one end of the mounting bolt extends to the inside of the brake disk and is threadedly connected to the brake disk.

[0010] Preferably, a limiting block is welded to the outer wall of one end of the brake spindle body, and a limiting groove is provided on the inner side of the brake disc.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When the brake spindle is stably braked, the servo motor drives the supporting shaft and the gear to reverse, and the reverse rotation of the gear drives the toothed disc, the connecting disc and the two sets of arc grooves to rotate forward. The forward rotation of the two sets of arc grooves pushes the distance between the two sets of connecting shafts to gradually shorten. The movement of the two sets of connecting shafts drives the two sets of clamping brake pads to move. The two sets of clamping brake pads slide on the inner side of the sliding groove, and the inner sides of the two sets of clamping brake pads gradually approach the outer wall of the brake disc. The outer wall of the brake disc is braked by the two sets of clamping brake pads, so that the brake disc brakes the main body of the brake spindle. The brake spindle is stably braked by setting the clamping brake pads. Through mechanical braking, the brake mechanism of the brake spindle has a simple structure, reliable action, large braking torque, rapid braking, and easy maintenance.

[0013] 2. When replacing the brake disc of the brake spindle, the operator uses an Allen wrench to spirally remove the mounting bolts, separate the brake disc from the brake spindle body, replace the new brake disc, and use the mounting bolts to fix the brake spindle body and the brake disc, and use the limit block to limit the limit groove, so that the brake disc of the brake spindle can be easily and quickly replaced, thereby effectively improving the maintenance efficiency of the brake spindle, shortening the maintenance time of the brake system, quickly restoring the braking performance of the device, and improving the safety of the device when in use.
