[0001] The utility model relates to the field of robots, in particular to a servo motor vibration reduction and heat dissipation structure for a heavy-load robot. Background Art

[0002] Heavy-load robots are industrial robots specially designed to perform heavy-load tasks. They usually have powerful power systems and structures, and can withstand and move relatively large weights and loads. The main application areas of heavy-load robots include manufacturing, logistics, construction, and mining, etc. These industries usually need to handle large components, heavy materials or perform high-intensity operations.

[0003] With the continuous improvement of the degree of industrial automation, heavy-duty robots have been widely used in manufacturing, logistics and other fields due to their high load, high precision and high efficiency. Servo motors are the core power components of heavy-duty robots, and their performance directly affects the overall working efficiency and stability of the robots.

[0004] However, during the operation of heavy-load robots, since heavy-load robots need to handle large components, heavy materials or perform high-intensity operations, these tasks are often accompanied by strong vibrations, which may cause serious damage to the servo motor itself and other related components, reducing the service life of the servo motor. Therefore, a servo motor shock absorption and heat dissipation structure for heavy-load robots is proposed to solve the above problems. Summary of the Invention

[0005] In order to make up for the above shortcomings, the utility model provides a shock-absorbing and heat-dissipating structure for a servo motor for a heavy-load robot, aiming to improve the problem in the prior art that "the robot is prone to vibration during operation, which easily causes the servo motor to follow the vibration, and long-term vibration is prone to damage, reducing the service life."

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a shock-absorbing and heat-dissipating structure of a servo motor for a heavy-load robot, comprising a main body, a buffer assembly being provided at the bottom end of the main body, the buffer assembly comprising a top plate, the top plate being installed at the bottom end of the main body, the bottom end of the top plate being fixedly connected to a moving block, the bottom end of the moving block being fixedly connected to a damping pad, the outer wall of the moving block being slidably connected to a damping frame, the damping pad being slidably connected to the inner wall of the damping frame, a vent being provided on the front surface of the damping frame, and the left side of the moving block being hinged to a connecting block.

[0022] 1. In the utility model, the servo motor is driven to vibrate by the heavy-load robot, so that the servo motor moves to extrude the moving block, causing the damping pad to slide on the inner wall of the damping frame. At the same time, the air in the damping frame is discharged from the vent to reduce the speed of movement of the top plate. At the same time, the extrusion slider and the spring are cooperated to make the spring expand and contract, so that the vibration of the body can be buffered, reducing damage to the servo motor and increasing the service life of the servo motor.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 、 Figure 3 、 Figure 4The utility model provides an embodiment: a servo motor shock absorption and heat dissipation structure for a heavy-load robot, including a body 1, the body 1 is a servo motor, the bottom end of the body 1 is provided with a buffer assembly, the buffer assembly includes a top plate 3 connected to the body 1 to provide support, the top plate 3 is installed at the bottom end of the body 1, the bottom end of the top plate 3 is fixedly connected to a supporting damping pad 311 and a moving block 310 that guides the body 1 at the same time, the bottom end of the moving block 310 is fixedly connected to a damping pad 311 made of rubber material, which can increase the friction with the inner wall of the damping frame 32. The vent hole 35 can reduce the speed of the top plate 3, thereby cooperating with the spring 36 to achieve a buffering effect of the damping pad 311. The outer wall of the moving block 310 is slidably connected to the damping frame 32 for providing support. The damping pad 311 is slidably connected to the inner wall of the damping frame 32. The front surface of the damping frame 32 is provided with a vent hole 35 with a small diameter, which can slowly circulate gas, thereby buffering the vibration force of the main body 1. The left side of the moving block 310 is hinged with a connecting block 39 that connects the moving block 310 to the slider 38.

[0032] Reference Figure 1 、 Figure 2 , the outer wall of the main body 1 is provided with a heat dissipation component for improving the heat dissipation efficiency of the servo motor body when running under heavy load. The heat dissipation component includes a large surface area so as to more effectively exchange heat with the air. The heat sink 2 is a prior art and is usually made of materials with good thermal conductivity such as aluminum alloy. It can quickly transfer the heat inside the servo motor to the surface of the heat sink 2. The heat sink 2 has a large surface area and can quickly contact the heat inside the motor with the air for heat dissipation, thereby improving the heat dissipation effect and ensuring that it can maintain stable performance under high load and long-term operation conditions, and prolonging its service life. The left side of the heat sink 2 is fixedly connected with a clip 21, which is stuck in the left slot of the card block 24 to limit the clip 21 of the heat sink 2.

[0033] Reference Figure 1 、 Figure 3 、 Figure 4The left side of the damping frame 32 is fixedly connected to a positioning frame 37 that supports the slider 38 and the spring 36. The inner wall of the positioning frame 37 is slidably connected to a slider 38 that can squeeze the spring 36 when moving, so that the spring 36 can be expanded and contracted, thereby achieving the effect of buffering the body 1. The connecting block 39 is hinged to the front surface of the slider 38. The slider 38 and the positioning frame 37 are elastically connected by the spring 36. One end of the spring 36 is fixedly connected to the left inner wall of the positioning frame 37, and the other end of the spring 36 is fixedly connected to the left side of the slider 38. The spring 36 is squeezed by the movement of the slider 38 to make the spring 36 expand and contract. The reverse force of the squeezing of the spring 36 can buffer the vibration of the body 1. The bottom end of the top plate 3 is fixedly connected to the telescopic rod 34, and the outer wall of the telescopic rod 34 is slidably connected to the telescopic sleeve 33. The telescopic rod 34 cooperates with the telescopic sleeve 33 to increase the stability of the top plate 3 and the bottom plate 31.

[0034] Reference Figure 1 、 Figure 3 、 Figure 4 The bottom end of the telescopic sleeve 33 is fixedly connected to a base plate 31 that provides support. Two groups of moving blocks 310, connecting blocks 39, and damping pads 311 are provided, and the two groups of moving blocks 310, connecting blocks 39, and damping pads 311 are symmetrically arranged with the center line of the damping frame 32 as the axis of symmetry. The base plate 31 is fixedly connected to the bottom end of the other group of moving blocks 310. Setting multiple groups can increase stability.

[0035] Reference Figure 1 、 Figure 2 The left front surface of the main body 1 is fixedly connected with a matching card slot, and the clip 21 is installed on the card block 24 on the front surface of the card block 24. A card slot is opened on the left side of the card block 24, and the clip 21 is clipped into the inner wall of the card slot. The top of the heat sink 2 is fixedly connected with a positioning block 23, and a heat dissipation copper tube 22 is installed on the front surface of the main body 1.

[0036] Working principle: When in use, the heavy-load robot is operated to cause the main body 1 to vibrate, and the main body 1 squeezes the top plate 3 to drive the moving block 310 to move downward, while the telescopic rod 34 slides on the inner wall of the telescopic sleeve 33 to provide support, and the damping pad 311 is driven to slide on the inner wall of the damping frame 32 through the moving block 310, and the gas in the damping frame 32 is discharged from the vent 35. The holes set through the vent 35 cooperate with the gas flow to reduce the moving speed of the damping pad 311 and the moving block 310, thereby improving the stability of the top plate 3 when moving, and at the same time, the moving block 310 moves to push the connecting block 39 and the slider 38, so that the slider 38 moves to squeeze the spring 36, thereby causing the spring 36 to expand and contract. The expansion and contraction of the spring 36 can buffer the squeezing force, thereby reducing the speed of the main body 1 and the force of buffering the vibration of the main body 1, thereby increasing the service life of the main body 1 and reducing the impact damage of the main body 1.

[0037] By installing the heat dissipation copper tube 22 on the front surface of the main body 1 and moving the heat sink 2 at the same time to drive the clip 21 to be clamped on the front surface of the clamping block 24 for installation, the heat inside the main body 1 can be transferred to the surface of the heat sink 2 through the cooperation of the heat sink 2 and the heat dissipation copper tube 22, and the heat on the heat sink 2 can be quickly taken away by the heat dissipation copper tube 22, thereby significantly improving the heat dissipation efficiency of the main body 1, thereby ensuring that it can maintain stable performance and extend its service life under high load and long-term operation conditions.
