Description

Technical Field

[0001] The utility model relates to the technical field of brake type braking components, in particular to a brake type braking component of a hollow integrated servo joint module. Background Technique

[0002] Joints are important components of robots. Different specifications of joints can be used to build different robot configurations according to needs, such as robotic arms and biped robots. Joints mainly consist of a driving motor and a reducer. The driving motor provides power, and under the action of the reducer, the power is output to drive the execution mechanism of the robot to move. With the development of mechatronics, robot components are developing towards the direction of light weight, integration, intelligence, and systematization.

[0003] Currently, in the prior art, most brake type braking components mostly decelerate by the friction of brake pads on the driving device. In order to have sufficient driving force, the brake type braking components often have a large volume, which will occupy most of the servo joint space, increasing the volume of the servo joint, and thus making it difficult for the robot to be miniaturized. In view of this, we propose a brake type braking component of a hollow integrated servo joint module. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a brake type braking component of a hollow integrated servo joint module, which can solve the problems raised in the above technical background.

[0005] To achieve the above purpose, the utility model proposes the following technical solutions:

[0006] A brake type braking component of a hollow integrated servo joint module, including a device main body. A brake component is arranged inside the device main body. The brake component includes an outer stator, which is arranged on the inner wall of the device main body. An inner stator is fixedly connected to the inner wall of the outer stator. A spring hole is opened on the bottom surface of the outer stator. One end of a spring is fixedly connected to the inner wall of the spring hole, and the other end of the spring is fixedly connected to the upper surface of an armature.

[0007] Preferably, a rotor is arranged below the armature. A square hole is opened on the surface of the rotor, and the rotor is arranged on the inner wall of the device main body.

[0008] Preferably, one end of a hydraulic driver is fixedly connected to the inner wall of the outer stator, and the other end of the hydraulic driver is sleeved on the inner wall of a brake pad.

[0009] Preferably, an inner baffle is arranged on the surface of the outer stator. Vent holes are opened on the surface of the inner baffle. An outer baffle is fixedly connected to the surface of the brake pad. Ventilation holes are opened on the surface of the outer baffle, and the ventilation holes are matched with the vent holes.

[0010] Preferably, the device body includes a driving device, the bottom surface of the driving device is fixedly connected to one end of the driving housing, the other end of the driving housing is fixedly connected to the upper surface of the output device, and a socket block is fixedly connected to the surface of the rotating shaft of the output device.

[0011] Preferably, a rotor is sleeved on the surface of the socket block, and the surface of the outer stator is fixedly connected to the inner wall of the driving housing.

[0012] Beneficial effects

[0013] The present utility model provides a brake type braking component of a hollow integrated servo joint module, which has the following beneficial effects:

[0014] (1). By providing the brake pads, the brake pads adopt a hollow structure. When the device body is running, the hollow structure can facilitate the routing of wires, and the hydraulic driver is installed on the surface of the outer stator, so that the required space of the brake assembly can be effectively saved, and thus the volume of the servo joint can be more effectively reduced.

[0015] (2). By providing the outer baffle, when the hydraulic driver drives the brake pads to fix the rotor, the outer baffle moves upward, so that the ventilation holes and the air exchange holes are communicated, so that when braking, the heat generated by the friction between the brake pads and the rotor can be dissipated out through the ventilation holes and the air exchange holes. When the hydraulic driver drives the brake pads to disengage from the rotor, the outer baffle moves downward, so that the ventilation holes and the air exchange holes are not communicated, so as to seal the rotor and prevent external dust from entering the rotor.

The other end of the driving housing 103 is fixedly connected to the upper surface of an output device 104. A socket block 102 is fixedly connected to the surface of the rotating shaft of the output device 104. A rotor 206 is sleeved on the surface of the socket block 102. The surface of the outer stator 201 is fixedly connected to the inner wall of the driving housing 103.

[0027] Inside the device main body 1 of the present utility model, a brake assembly 2 is provided. The brake assembly 2 includes: an outer stator 201, which is disposed on the inner wall of the device main body 1. The inner wall of the outer stator 201 is fixedly connected to an inner stator 203. A spring hole 202 is formed on the bottom surface of the outer stator 201. One end of a spring 204 is fixedly connected to the inner wall of the spring hole 202, and the other end of the spring 204 is fixedly connected to the upper surface of an armature 205. A rotor 206 is disposed below the armature 205. A square hole 207 is formed on the surface of the rotor 206. The rotor 206 is disposed on the inner wall of the device main body 1. One end of a hydraulic actuator 208 is fixedly connected to the inner wall of the outer stator 201, and the other end of the hydraulic actuator 208 is sleeved with the inner wall of a brake pad 209. The brake pad 209 adopts a hollow structure. When the device main body 1 is operating, the hollow structure can facilitate the routing of wires. The hydraulic actuator 208 is installed on the surface of the outer stator 201, so that the required space of the brake assembly 2 can be effectively saved, and thus the volume of the servo joint can be more effectively reduced.

[0028] Embodiment 2: On the basis of Embodiment 1, please refer to Figures 5 - 6 , the surface of the outer stator 201 is connected to an inner baffle 210. Vent holes 211 are formed on the surface of the inner baffle 210. An outer baffle 212 is fixedly connected to the surface of the brake pad 209. Vent holes 213 are formed on the surface of the outer baffle 212. The vent holes 213 are matched with the vent holes 211. By providing the outer baffle 212, when the hydraulic actuator 208 drives the brake pad 209 to fix the rotor 206, the outer baffle 212 moves upward, so that the vent holes 211 and the vent holes 213 are communicated. Thus, when braking, the heat generated by the friction between the brake pad 209 and the rotor 206 can be dissipated to the outside through the vent holes 211 and the vent holes 213. When the hydraulic actuator 208 drives the brake pad 209 to disengage from the rotor 206, the outer baffle 212 moves downward, so that the vent holes 211 and the vent holes 213 are not communicated, thereby sealing the rotor 206 and preventing external dust from entering the inside of the rotor 206.

[0029] During use, when the hydraulic actuator 208 drives the brake pad 209 to fix the rotor 206, the outer baffle 212 moves upward, so that the vent holes 211 and the vent holes 213 are communicated. Thus, when braking, the heat generated by the friction between the brake pad 209 and the rotor 206 can be dissipated to the outside through the vent holes 211 and the vent holes 213. When the hydraulic actuator 208 drives the brake pad 209 to disengage from the rotor 206, the outer baffle 212 moves downward, so that the vent holes 211 and the vent holes 213 are not communicated, thereby sealing the rotor 206.
