[0002] Disc brakes have been widely used in machine tools, chemical industry, lifting equipment and other fields. They are characterized by fast braking response, large braking force and easy installation.

[0003] However, as modern industry places increasingly higher demands on the safety and reliability of equipment, traditional brakes may have problems with malfunctions that are not easily detected during use. Moreover, most disc brakes on the market are air-operated brakes, which pose safety hazards in emergency situations such as power outages or air supply interruptions. Utility Model Content

The lever arm can swing up and down relative to the support sleeve; the two ends of the reset spring are respectively fixed to the upper lever arm and the lower lever arm by the second bolts, which can ensure timely disengagement when the brake is released; the friction plates are respectively bonded to the upper lever arm and the lower lever arm; the cylinder assembly is fixed to the lower lever arm by the second nut, and an adjusting screw is installed on the upper lever arm to control the up and down swing angle of the upper and lower lever arms.

[0007] Compared with existing technologies, the advantages of this invention are as follows: This brake uses spring braking, and the brake can only be released under air intake conditions, effectively preventing accidental slippage or loss of control in special circumstances such as power outages, greatly improving safety performance. Furthermore, sensors are installed in the moving parts of the brake, which can detect the brake's status in real time, such as braking action and braking time. This allows for timely detection of potential brake problems, enabling early maintenance and adjustments, and ensuring stable equipment operation. Attached Figure Description

[0010] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0011] Depend on Figure 1 , Figure 2As can be seen, this utility model includes: a cylinder assembly; the cylinder assembly includes: a cylinder head 1, a cylinder body 5, a piston 2, a first set of bolts 3, a first sealing ring 4, a second sealing ring 6, and a brake spring assembly 15; the first sealing ring 4 is mounted on the piston 2; the second sealing ring 6 is mounted on the cylinder body 5; the cylinder head 1 and the cylinder body 5 are connected by the first set of bolts 3; a brake spring assembly 15 is arranged between the cylinder head 1 and the piston 2; the piston 2 can move up and down relative to the cylinder head 1; it also includes: an actuator arm; the actuator arm includes: an upper actuator arm 12, a lower actuator arm 14, a second bolt 10, a return spring 11, a friction plate 13, a support sleeve 16, a connecting body 17, a third bolt 18, and a first nut 19; the upper actuator arm 12 and the lower actuator arm 14 are clamped by the connecting body 17; a support sleeve 16 is installed between the connecting body 17 and the upper actuator arm 12 and the lower actuator arm 14 respectively, and is connected and fastened by the third bolt 18 and the first nut 19; the upper actuator arm 12 and the lower actuator arm 14 are clamped by the connecting body 17; a first ... first bolt 17; the upper Arm 12 and lower arm 14 can swing up and down relative to support sleeve 16; the two ends of the reset spring 11 are respectively fixed to upper arm 12 and lower arm 14 by second bolts 10, which can ensure timely disengagement when the brake is released; the friction plate 13 is respectively bonded to upper arm 12 and lower arm 14; the cylinder assembly is fixed to lower arm 14 by second nut 7, and an adjusting screw 9 is installed on upper arm 12 to control the up and down swing angle of upper arm 12 and lower arm 14. After adjustment, it is fixed by third nut 8 to prevent loosening; it also includes: proximity sensor 20; the proximity sensor 20 is fixed to upper arm 12 by fourth bolt 21; it also includes: sensor bracket 23; the sensor bracket 23 is fixed to lower arm 14 by fifth bolt 22; when upper arm 12 and lower arm 14 swing up and down, proximity sensor 20 and sensor bracket 23 move away from or closer to each other, that is, output the open or closed signal of the brake.

[0012] The working principle of this utility model is as follows:

[0013] When compressed air from the outside enters the cylinder through the air inlet A, under the action of the compressed air, piston 2 moves downward against the force of brake spring assembly 15, creating a gap between the top of piston 2 and adjusting screw 9. Under the action of return spring 11, upper arm 12 and lower arm 14 swing around support sleeve 16 towards the center, friction plate 13 opens, and brake disengages. At this time, proximity sensor 20 approaches sensor bracket 23 and outputs brake disengagement signal.

[0014] When compressed air is discharged from port A, piston 2, under the action of brake spring assembly 15, pushes piston 2 upward, causing the top of piston 2 to press against adjusting screw 9, overcoming the force of return spring 11. Upper arm 12 and lower arm 14 swing to both sides around support sleeve 16, friction plate 13 clamps, and brake clamps brake disc to achieve braking. At the same time, proximity sensor 20 moves away from sensor bracket 23, outputting brake signal.
