Description

Technical Field

[0001] This utility model belongs to the field of servo driver technology, and in particular relates to a servo driver heat dissipation device. Background Technology

[0002] Servo drives are the core control components of servo systems, used to precisely control the movement of servo motors. By receiving command signals from the host controller and combining them with motor feedback, they achieve closed-loop control. They are widely used in high-precision fields such as industrial automation, robotics, and CNC machine tools. In order to avoid overheating during the use of servo drives, heat dissipation devices are usually used. A heat pipe cooling device for an AC servo driver is disclosed in document CN222302292U, including a base plate with a fan frame on its upper surface. A screw passes through an ear plate and is threaded into a mounting hole, connecting the driver body to an upper heat spreader. When the driver body generates heat during operation, heat is conducted through heat pipes containing ethanol. The upper and lower heat spreaders connect multiple heat pipes into a single plane, all made of copper with good thermal conductivity, facilitating the transfer of heat generated by the driver body to the heat pipes. The lower and upper grooves fit snugly against the surface of the heat pipes, facilitating heat conduction. Multiple heat dissipation fins increase the contact area between the heat pipes and air, rapidly dissipating heat. Simultaneously, a cooling fan is activated to accelerate airflow between adjacent heat dissipation fins, reducing heat accumulation and ensuring the driver body temperature remains within the allowable operating range, thus improving the driver body's lifespan. However, it still has the following drawbacks in practical use: 1. The heat pipe cooling device mentioned above mounts the driver body onto the heat spreader plate via screws and lugs. However, in use, due to the variety of sizes of the driver body, the different positions of the lugs for different sizes of driver bodies, and the fixed position of the mounting holes on the heat spreader plate, it can only be used for driver bodies of specific sizes, resulting in a small range of applicability and low practicality. 2. In the heat pipe cooling device mentioned above, the outer wall of the heat pipe is fixedly connected with uniformly distributed heat dissipation fins. The heat dissipation fins are installed in a fixed connection with the heat pipe, which makes it inconvenient to replace individual heat pipes or heat dissipation fins during use, increasing maintenance costs.

[0003] To address these issues, we provide a servo driver heat dissipation device. Utility Model Content

[0004] The purpose of this utility model is to provide a servo driver heat dissipation device. The first threaded rod and the moving plate drive the second mounting frame to move in the left and right direction, and the second threaded rod drives the mounting block to move in the front and back direction. Thus, the mounting block can install driver bodies of different sizes, solving the problem that it is not convenient to fix them on driver bodies of different sizes. At the same time, the third threaded rod drives the U-shaped frame to make the heat dissipation fins fit on the heat pipe, and the heat dissipation fins are fixed on the U-shaped frame by the locking block, solving the problem that it is not convenient to replace individual heat dissipation fins.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a servo driver heat dissipation device, comprising a half-sleeve, a base, and a heat spreader plate fixedly connected to the top of the base. The driver body is mounted on the heat spreader plate via a mounting assembly. The mounting assembly includes two first mounting frames fixedly connected to the front and rear ends of the lower surface of the heat spreader plate, respectively. A first threaded rod is rotatably connected between the two first mounting frames. First sliders are threadedly connected to both sides of the outer wall of the first threaded rod. A movable plate is fixedly connected to the bottom of the first slider. Protrusions are fixedly connected to the front and rear ends of the upper surface of the movable plate. The free ends of the protrusions are movably connected to the inner sides of the first mounting frames, respectively. A connecting rod is fixedly connected to one outer wall of each protrusion. The end of the connecting rod away from the protrusion extends to the outside of the first mounting frame and is fixedly connected to a first... The second mounting frame has a second threaded rod rotatably connected inside. The front and rear ends of the outer wall of the second threaded rod are threaded with second sliders. The top of each second slider is fixedly connected with a mounting block for fixing the driver body. Multiple heat pipes run through the heat spreader. Each heat pipe is equipped with a heat dissipation component. The heat dissipation component includes two third threaded rods rotatably connected to the outer walls of the two sides of the base. The front and rear ends of the outer walls of the third threaded rods are threaded with third sliders. A U-shaped frame is fixedly connected to one side of the third slider. Multiple locking blocks are snapped into the inside of the U-shaped frame. The same heat dissipation fin is fixedly connected between adjacent left and right locking blocks. Multiple half-rings are fixedly connected at equal intervals on the heat dissipation fin. The front and rear adjacent half-rings are fitted onto the same heat pipe.

[0006] A further feature of this invention is that: mounting brackets are fixedly connected to both sides of the adjacent first mounting frames, and both ends of the first threaded rod pass through the mounting brackets and are fixedly connected to the first knobs.

[0007] A further feature of this invention is that the two ends of the second threaded rod extend to the front and rear ends of the outer side of the second mounting frame and are fixedly connected to a second knob.

[0008] A further feature of this invention is that ear plates are fixedly connected to the front and rear ends of both sides of the outer wall of the driver body, and a fixing rod is passed through each ear plate. The bottom end of the fixing rod is fixedly connected to the top of the mounting block, and a fastening nut is threadedly connected to the top end of the fixing rod.

[0009] A further feature of this invention is that cooling fans for dissipating heat from the heat dissipation fins are fixedly connected to both sides of the front and rear end faces of the base.

[0010] A further feature of this invention is that a third knob is fixedly connected to one end of each of the third threaded rods.

[0011] A further feature of this invention is that a cover plate is rotatably connected to the opening of the U-shaped frame, and multiple protrusions are fixedly connected at equal intervals to the inner wall of the U-shaped frame and the cover plate. Grooves that cooperate with the protrusions are provided on the front and rear end faces of the card block.

[0012] A further feature of this invention is that the lower end of the cover plate is rotatably connected to the longitudinal support arm below the U-shaped frame, and a fastening bolt is threaded onto the longitudinal support arm above the U-shaped frame, with the fastening bolt penetrating the upper end of the cover plate.

[0013] This utility model has the following beneficial effects: 1. This utility model, by setting up an installation component, allows for the rotation of a first knob, which in turn drives a first threaded rod to rotate. The first threaded rod, through a first slider, drives a moving plate and a second mounting frame to move. When the second mounting frame moves to a designated position in the left-right direction, the first knob stops rotating, and a second knob is rotated. The second knob drives a second threaded rod to rotate, which, through a second slider, drives a mounting block to move. When the mounting block moves to a designated position in the front-back direction, the second knob stops rotating, and the driver body is fixed to the heat spreader plate via the mounting block. This facilitates heat dissipation for driver bodies of different sizes, expands the scope of application, and improves practicality.

[0014] 2. This utility model, by setting up a heat dissipation component, allows for easy replacement of the heat pipe when the heat pipe needs to be replaced. Rotating the third knob causes the third threaded rod to rotate, which in turn causes the U-shaped frame to separate via the third slider, thus separating the heat dissipation fins from the heat pipe. This facilitates heat pipe replacement. When the heat dissipation fins need to be replaced, tightening the fastening bolts separates them from the U-shaped frame and the cover plate. Rotating the cover plate allows the retaining block to be removed from the U-shaped frame, further simplifying heat dissipation fin replacement. This design facilitates the replacement of both the heat pipe and the heat dissipation fins, reducing maintenance costs. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1 Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this is the first embodiment of the present invention. This embodiment provides a servo driver heat dissipation device, including a half-sleeve 604a, a base 1, and a heat spreader 2 fixedly connected to the top of the base 1. The heat spreader 2 is mounted on the driver body 3 via a mounting assembly 4. The mounting assembly 4 includes a first mounting frame 401, a first threaded rod 402, a moving plate 403, a second mounting frame 404, a second threaded rod 405, and a mounting block 406. The first threaded rod 402 and the moving plate 403 drive the second mounting frame 404 to move in the left and right directions, and the second threaded rod 405 drives the mounting block 406 to move in the front and back directions. Thus, the mounting block 406 can be used to install driver bodies 3 of different sizes, solving the problem that existing devices are inconvenient to fix on driver bodies 3 of different sizes.

[0028] Specifically, two first mounting frames 401 are provided and fixedly connected to the front and rear ends of the lower surface of the heat spreader 2, respectively.

The moving plate 403 is used to drive the second mounting frame 404 to move. The protrusion 403b and the connecting rod 403c are used to connect the moving plate 403 and the second mounting frame 404.

The second threaded rod 405 and the second slider 406a are used to drive the mounting block 406 to move. The mounting block 406 is used to fix the driver body 3 on the heat exchange plate 2. The heat pipes 5 are used to dissipate heat from the heat exchange plate 2.

[0029] Furthermore, mounting brackets 401a are fixedly connected to both sides of the first mounting frame 401, and the two ends of the first threaded rod 402 pass through the mounting bracket 401a and are fixedly connected to the first knob 402a. The two ends of the second threaded rod 405 extend to the front and rear ends of the outer side of the second mounting frame 404 and are fixedly connected to the second knob 405a. The front and rear ends of both sides of the driver body 3 are fixedly connected to ear plates 301. Each ear plate 301 has a fixing rod 406b passing through it. The bottom end of the fixing rod 406b is fixedly connected to the top of the mounting block 406, and the top end of the fixing rod 406b is threadedly connected to a fastening nut 406c.

[0030] The operation process of this embodiment is as follows: Rotate the first knob 402a, which drives the first threaded rod 402 to rotate. The first threaded rod 402 drives the moving plate 403 and the second mounting frame 404 to move through the first slider 403a. When the second mounting frame 404 moves to the designated position in the left-right direction, stop rotating the first knob 402a and rotate the second knob 405a. The second knob 405a drives the second threaded rod 405 to rotate. The second threaded rod 405 drives the mounting block 406 to move through the second slider 406a. When the mounting block 406 moves to the designated position in the front-back direction, stop rotating the second knob 405a and fix the driver body 3 to the heat spreader 2 through the mounting block 406.

[0031] Example 2 Please see Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9 As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: heat dissipation components 6 are provided on the heat pipes 5. The heat dissipation components 6 include a third threaded rod 601, a U-shaped frame 602, a locking block 603, and heat dissipation fins 604. The third threaded rod 601 drives the U-shaped frame 602 to make the heat dissipation fins 604 fit on the heat pipes 5, and the locking block 603 fixes the heat dissipation fins 604 on the U-shaped frame 602, which solves the problem that it is inconvenient to replace individual heat dissipation fins 604 in the existing embodiments.

[0032] Specifically, two third threaded rods 601 are provided and rotatably connected to the outer walls of both sides of the base 1. The front and rear ends of the outer walls of the third threaded rods 601 are threaded with third sliders 601b. A U-shaped frame 602 is fixedly connected to one side of the third slider 601b. Multiple locking blocks 603 are engaged inside the U-shaped frame 602. The same heat dissipation fin 604 is fixedly connected between adjacent locking blocks 603 on the left and right sides. Multiple half-rings are fixedly connected at equal intervals on the heat dissipation fin 604. The front and rear adjacent half-rings 604a are fitted onto the same heat pipe 5. The third threaded rods 601 and the third sliders 601b are used to drive the U-shaped frame 602 to move, thereby separating the front and rear adjacent heat dissipation fins 604 from the heat pipe 5. The U-shaped frame 602 and the locking blocks 603 are used to install the heat dissipation fins 604. The heat dissipation fins 604 are used to dissipate heat from the heat pipe 5.

[0033] Furthermore, cooling fans 101 for dissipating heat from the heat sink 604 are fixedly connected to both sides of the front and rear end faces of the base 1. A third knob 601a is fixedly connected to one end of the third threaded rod 601; The opening of the U-shaped frame 602 is rotatably connected to a cover plate 602a. Multiple protrusions 602b are fixedly connected at equal intervals on the inner wall of the U-shaped frame 602 and the cover plate 602a. The front and rear end faces of the card block 603 are provided with grooves 603a that cooperate with the protrusions 602b. The lower end of the cover plate 602a is rotatably connected to the longitudinal support arm below the U-shaped frame 602, and the longitudinal support arm above the U-shaped frame 602 is threaded with a fastening bolt 602c, which passes through the upper end of the cover plate 602a.

[0034] The rest of the structure is the same as in Example 1.

[0035] The operation process of this embodiment is as follows: When it is necessary to replace the heat pipe 5, rotate the third knob 601a. ​​The third knob 601a drives the third threaded rod 601 to rotate. The third threaded rod 601 drives the U-shaped frame 602 to separate through the third slider 601b, thereby separating the heat dissipation fins 604 from the heat pipe 5, which facilitates the replacement of the heat pipe 5. When it is necessary to replace the heat dissipation fins 604, tighten the fastening bolt 602c, so that the fastening bolt 602c separates from the U-shaped frame 602 and the cover plate 602a, and rotate the cover plate 602a to remove the clip 603 from the U-shaped frame 602, which facilitates the replacement of the heat dissipation fins 604.
