Description

Technical Field

[0001] This utility model relates to the field of robot component technology, and in particular to an output component for a robot joint module. Background Technology

[0002] With the rapid penetration of robotics technology into fields such as industrial manufacturing, medical rehabilitation, and home services, increasingly higher demands are being placed on the flexibility, load-bearing capacity, and motion precision of robot joints. As the core unit for robots to perform complex movements, the performance of the joint module directly determines the overall operational efficiency of the robot. The output components used in robot joint modules, as a key bridge connecting the joint's power source and the external actuator, must accurately transmit power and stably output motion.

[0003] In the existing technology, the output component of a joint module for robots needs to be frequently installed and disassembled during the assembly, debugging, maintenance, and functional upgrade of the robot to adapt to the replacement of actuators or the multi-joint collaborative debugging needs in different scenarios. However, the traditional output component can only be installed and disassembled by multiple bolts, which has low installation and disassembly efficiency and poor practicality. Utility Model Content

[0004] This utility model mainly provides an output component for robot joint modules that is not limited to a single bolt, and in most cases, the new installation and removal method is more convenient and faster.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an output component for a joint module of a robot, including a bracket, a first motor installed inside the bracket, the output end of the first motor passing through the front end of the bracket and fixedly connected to a drive shaft, prismatic clamping plates provided on both sides of the rear end of the bracket, a drive structure for driving the two prismatic clamping plates to move in opposite directions or in the same direction provided inside the bracket, and multiple arc-shaped clamping blocks provided inside each of the two prismatic clamping plates.

[0006] Preferably, the driving structure includes a second motor mounted on the inner wall of the bracket. The output end of the second motor is fixed with a bidirectional screw. Both ends of the outer wall of the bidirectional screw are threadedly connected to movable plates. The ends of the two movable plates away from the bidirectional screw are slidably connected to a limiting post. One end of each of the two movable plates is fixed with a connecting block. The ends of the two connecting blocks away from the movable plates pass through the rear end of the bracket and are respectively fixed to two prismatic clamping plates. By running the second motor, the bidirectional screw is driven to rotate, causing the two movable plates to move towards or in opposite directions under the limitation of the limiting post. This causes the two prismatic clamping plates connected by the two connecting blocks to move towards or in opposite directions, enabling the bracket as a whole to be clamped and disassembled from the outside.

[0007] Preferably, a fixing frame is fixed to one end of each of the two prismatic clamps facing away from each other, and an electric telescopic rod is installed on one end of each of the two fixing frames facing away from each other. A connecting plate is fixed to one end of each of the two electric telescopic rods facing away from each other. The two sets of arc-shaped clamps are fixed to the two connecting plates respectively. By operating the electric telescopic rods, the connecting plates can be moved, thereby moving the multiple arc-shaped clamps fixed to them. The arc-shaped clamps are moved between the two prismatic clamps. When the two prismatic clamps move towards each other, the arc-shaped clamps will contact the external position that needs to be clamped and fixed in advance. This makes it easier to clamp and install the device on curved external positions, resulting in better performance and greater practicality.

[0008] Preferably, both of the prismatic clamping plates have a connecting groove that matches the arc-shaped clamping block. When the arc-shaped clamping block is not in use, it will be placed in the connecting groove to avoid affecting the clamping and fixing of the prismatic clamping plates.

[0009] Preferably, the end of the bidirectional screw away from the second motor is rotatably connected to the bracket, both ends of the limiting post are fixed to the bracket, and the rear end of the bracket has a moving groove that matches the connecting block. By rotatably connecting the end of the bidirectional screw away from the second motor to the bracket, both ends of the bidirectional screw have a point of force, making its operation more stable.

[0010] Preferably, a mounting plate is fixed to one of the opposite ends of the two prismatic clamps, and multiple mounting holes are provided in both mounting plates. By setting up the mounting plates and mounting holes, the device retains the traditional bolt installation and removal while making clamping and removal more portable. In certain situations where clamping and removal are not suitable, traditional bolt installation and removal can still be used, making it more practical.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the operation of the second motor drives the bidirectional screw to rotate, causing the two moving plates to move towards or away from each other under the limitation of the limiting post. This, in turn, causes the two prismatic clamping plates connected by the two connecting blocks to move towards or away from each other, enabling the entire bracket to be clamped and disassembled from the outside world. This makes installation and disassembly more convenient. Furthermore, the operation of the electric telescopic rod can drive the connecting plates to move, thereby moving the multiple arc-shaped clamping blocks fixed to them. The arc-shaped clamping blocks move between the two prismatic clamping plates. When the two prismatic clamping plates move towards each other, the arc-shaped clamping blocks will first contact the external position that needs to be clamped and fixed, making it easier to clamp and disassemble the device at curved external positions. This method is more effective and practical. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figures 1-4 This utility model provides a technical solution: an output component for a robot joint module, including a bracket 1, a first motor 2 installed inside the bracket 1, the output end of the first motor 2 passing through the front end of the bracket 1 and fixedly connected to a drive shaft 3, and prismatic clamping plates 4 provided on both sides of the rear end of the bracket 1. A drive structure 7 is provided inside the bracket 1 for driving the two prismatic clamping plates 4 to move in opposite directions or in the same direction. Multiple arc-shaped clamping blocks 12 are provided inside each of the two prismatic clamping plates 4. By operating the first motor 2, the drive shaft 3 is driven to rotate, thereby driving the joint module installed on the drive shaft 3 to operate. By operating the drive structure 7, the two prismatic clamping plates 4 can be driven to move in opposite directions or in the same direction, so that the bracket 1 as a whole can be clamped and disassembled from the outside, making installation and disassembly more convenient.

[0021] like Figure 1-4As shown, the drive structure 7 includes a second motor 701 mounted on the inner wall of the bracket 1. The output end of the second motor 701 is fixed with a bidirectional screw 702. Both ends of the outer wall of the bidirectional screw 702 are threadedly connected to movable plates 703. The ends of the two movable plates 703 away from the bidirectional screw 702 are slidably connected to a limiting post 704. One end of each of the two movable plates 703 is fixed with a connecting block 705. The ends of the two connecting blocks 705 away from the movable plates 703 pass through the rear end of the bracket 1 and are respectively fixed to two prismatic clamping plates 4. By running the second motor 701, the bidirectional screw 702 is driven to rotate, causing the two movable plates 703 to move towards or away from each other under the limitation of the limiting post 704. This causes the two prismatic clamping plates 4 connected by the two connecting blocks 705 to move towards or away from each other, so that the bracket 1 as a whole can be clamped and disassembled from the outside.

[0022] like Figure 1-4 As shown, a fixing frame 9 is fixed to one end of each of the two prismatic clamping plates 4 facing away from each other. An electric telescopic rod 10 is installed on one end of each of the two fixing frames 9 facing away from each other. A connecting plate 11 is fixed to one end of each of the two electric telescopic rods 10 facing away from each other. The two sets of arc-shaped clamping blocks 12 are fixed to the two connecting plates 11 respectively. By operating the electric telescopic rod 10, the connecting plate 11 can be moved, thereby moving the multiple arc-shaped clamping blocks 12 fixed thereto. The arc-shaped clamping blocks 12 are moved between the two prismatic clamping plates 4. When the two prismatic clamping plates 4 move towards each other, the arc-shaped clamping blocks 12 will contact the external position that needs to be clamped and fixed in advance. This makes it easier to clamp and install the device on the external curved position, which is more effective and practical.

[0023] like Figure 1-4 As shown, each of the two prismatic clamping plates 4 has a connecting groove 13 that matches the arc-shaped clamping block 12. With the setting of the connecting groove 13, when the arc-shaped clamping block 12 is not in use, it will be placed in the connecting groove 13 to avoid affecting the clamping and fixing of the prismatic clamping plate 4.

[0024] like Figure 1-4 As shown, the end of the bidirectional screw 702 away from the second motor 701 is rotatably connected to the bracket 1, and both ends of the limiting post 704 are fixed to the bracket 1. The rear end of the bracket 1 has a moving groove 8 that matches the connecting block 705. By rotatably connecting the end of the bidirectional screw 702 away from the second motor 701 to the bracket 1, both ends of the bidirectional screw 702 have a point of force, making its operation more stable.

[0025] like Figure 1-4 As shown, mounting plates 5 are fixed to the opposite ends of the two rhomboid clamping plates 4. Multiple mounting holes 6 are opened in both mounting plates 5. With the setting of mounting plates 5 and mounting holes 6, the device retains the traditional bolt installation and removal on the basis of more portable clamping installation and removal. In certain situations where clamping installation and removal is not suitable, traditional bolt installation and removal can still be used, making it more practical.

[0026] The device's operation and working principle are as follows: When in use, the first motor 2 drives the connecting drive shaft 3 to rotate, thereby driving the joint module mounted on the connecting drive shaft 3. The second motor 701 drives the bidirectional screw 702 to rotate, causing the two moving plates 703 to move towards or away from each other under the limitation of the limiting post 704. This causes the two prismatic clamping plates 4 connected by the two connecting blocks 705 to move towards or away from each other, allowing the bracket 1 to be clamped and disassembled from the outside world more conveniently. Furthermore, the operation of the electric telescopic rod 10 can move the connecting plate 11, thereby moving the multiple arc-shaped clamping blocks 12 fixed to it. The arc-shaped clamping blocks 12 move between the two prismatic clamping plates 4. When the two prismatic clamping plates 4 move towards each other, the arc-shaped clamping blocks 12 will contact the external position that needs to be clamped and fixed beforehand, making it easier to clamp and disassemble curved external positions. This method is more effective and practical.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
