Description

Technical Field

[0001] This utility model relates to the field of air-cooled servo motors, and in particular to a guide plate for an air-cooled servo motor that is easy to disassemble and replace. Background Technology

[0002] In the field of industrial automation, servo motors, as core drive components, are widely used in CNC machine tools, robots, automated production lines, and other equipment. Air-cooled servo motors, with their advantages of simple structure, low cost, and easy maintenance, have become the preferred heat dissipation solution in many industrial scenarios. They dissipate the heat generated by the motor through airflow, preventing performance degradation, shortened lifespan, or even failure due to overheating. However, as industrial production develops towards higher precision, higher speed, and higher load, higher demands are placed on the heat dissipation efficiency and reliability of air-cooled servo motors.

[0003] Currently, air-cooled servo motors mostly use a shroud structure to assist in heat dissipation. The shroud is usually fixed to the motor body by bolts, clips, etc. Although this installation method is sturdy, in actual use, when the shroud is damaged or the heat dissipation fins need to be replaced, the existing connection method is cumbersome to operate, and disassembling the shroud is not only time-consuming and laborious. In order to address this technical problem, this application proposes a shroud for air-cooled servo motors that is easy to disassemble and replace. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a conveniently disassembled and replaceable air-cooled servo motor guide plate. Initial positioning is achieved through the cooperation of a retaining ring and a retaining slot, followed by a secure fixation through the linkage of a limiting insert and a retaining block. Installation can be completed quickly without complex tools, and disassembly is easily achieved by reversing the operation. This facilitates subsequent replacement of the heat dissipation fins, significantly reducing maintenance time and operational difficulty, and improving the overall maintenance efficiency of the equipment. The installation and removal of the guide plate are convenient and efficient. The heat dissipation system is rationally designed; the airflow generated by the fan rotation is guided by the guide plate and precisely blows onto the heat dissipation fins, effectively removing heat. Simultaneously, the retaining ring on the inner wall of the guide plate abuts against the heat dissipation fins from the rear, and the connection between the insert and the slot provides double protection for the stability of the heat dissipation fins, preventing them from shaking during equipment operation. This ensures both effective heat dissipation and extends the service life of the heat dissipation components.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A guide plate for an easily disassembled and replaceable air-cooled servo motor includes a motor body. A rotor central shaft is provided at the front end of the motor body. A fixing block one is fixedly connected to the top outer wall of the motor body. A fixing block two is connected to the rear bottom side of the fixing block one through a limiting component. The fixing block two is fixedly connected to the bottom outer wall of the motor body. Multiple heat dissipation fins are provided on the outer wall of the motor body. A fan is provided at the rear end of the motor body. A guide shroud is provided at the rear end of the fan. A retaining ring is fixedly connected to the front inner wall of the guide shroud through a connecting block.

[0006] Furthermore, the limiting component includes two retaining rings rotatably connected to the bottom rear end of the fixed block. A limiting groove is formed on the outer wall of the bottom end of the retaining ring, and a limiting insert is provided in the limiting groove.

[0007] Furthermore, the outer wall of the motor body is provided with multiple slots, and a plug is provided in the slot. The length of the plug is less than that of the slot, and the plug is fixedly connected to the heat dissipation fins.

[0008] Furthermore, the outer wall of the flow guide is provided with a slot, the size of which is adapted to the size of the retaining ring.

[0009] Furthermore, the limiting insert is U-shaped, and both the left and right ends of the inner side of the limiting insert are fixedly connected to a locking block.

[0010] Furthermore, protruding plates are fixedly connected to both the left and right ends of the outer side of the limiting insert.

[0011] Furthermore, the rear outer wall of the air guide is provided with multiple through holes to facilitate the fan drawing in air.

[0012] Furthermore, a junction box is fixedly connected to the front outer wall of the top of the motor body.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the initial positioning is achieved through the cooperation of the retaining ring and the retaining groove, and then the stable fixation is completed by the linkage of the limiting insert and the retaining block. Installation can be completed quickly without complicated tools, and disassembly can be easily removed by reversing the operation. This provides convenience for subsequent replacement of heat dissipation fins, greatly reduces maintenance time and operation difficulty, improves the overall maintenance efficiency of the equipment, and makes the operation of installing and removing the air guide cover convenient and efficient.

[0014] 2. In this utility model, the heat dissipation system is reasonably designed. The airflow generated by the fan rotation is guided by the air guide and accurately blows onto the heat dissipation fins, effectively removing heat. At the same time, the retaining ring on the inner wall of the air guide abuts against the heat dissipation fins from the rear end. With the connection of the plug and the slot, the stability of the heat dissipation fins is doubly guaranteed, preventing them from shaking during equipment operation. This ensures the heat dissipation effect and extends the service life of the heat dissipation components. Attached Figure Description

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1-3This utility model provides an embodiment of a guide plate for a wind-cooled servo motor that is easy to disassemble and replace. The guide plate includes a motor body 1, a rotor central shaft 2 at the front end of the motor body 1, a fixing block 5 fixedly connected to the top outer wall of the motor body 1, and two retaining rings 9 rotatably connected to the rear end of the fixing block 5. The two retaining rings 9 hold the guide shroud 8 in place, thereby limiting the guide shroud 8. A limiting groove 11 is formed on the bottom outer wall of the retaining rings 9. By inserting limiting inserts 15 into the two limiting grooves 11, the two retaining rings 9 can be limited, preventing rotation and ensuring that the retaining rings 9 can stably limit the guide shroud 8. Limiting inserts 15 are provided in the limiting grooves 11, and the retaining rings... A fixing block 7 is provided at the bottom of the 9, and the fixing block 7 is fixedly connected to the bottom outer wall of the motor body 1. The outer wall of the motor body 1 is provided with multiple heat dissipation fins 6. The heat generated by the motor body 1 during operation will be transferred to the heat dissipation fins 6. A fan 12 is provided at the rear end of the motor body 1. The fan 12 is connected to the rotor central shaft 2. When the motor body 1 is working, the fan 12 can be rotated through the rotor central shaft 2. A flow guide shroud 8 is provided at the rear end of the fan 12. A retaining ring 17 is fixedly connected to the inner wall of the front end of the flow guide shroud 8 through a connecting block. After the flow guide shroud 8 is installed, the retaining ring 17 can abut against the heat dissipation fins 6 from the rear end of the heat dissipation fins 6, thereby ensuring the stability of the heat dissipation fins 6 in the slot 13.

[0019] Reference Figure 4-6The outer wall of the motor body 1 has multiple slots 13, and each slot 13 contains a plug 16, the length of which is less than that of the slot 13. The plug 16 is fixedly connected to the heat sink fins 6. By inserting the plug 16 into the slot 13, the heat sink fins 6 can be installed onto the outer wall of the motor body 1. This design also allows the heat sink fins 6 to be replaced, so that damaged heat sink fins 6 can be replaced individually. The outer wall of the air guide shroud 8 has a slot 14, the size of which is adapted to the size of the retaining ring 9. By setting the slot 14 to cooperate with the retaining ring 9, the retaining ring 9 can limit the position of the air guide shroud 8. The limiting insert 15 is U-shaped. Both ends of the inner side of the limiting insert 15 are fixedly connected to locking blocks 3. During the insertion of the limiting insert 15 into the limiting groove 11, the two retaining rings 9 are propped open by the locking blocks 3. When the limiting insert 15 is fully inserted, the locking blocks 3 disengage from the retaining rings 9, and the limiting insert 15 returns to its original shape, thus limiting the two retaining rings 9 and preventing them from rotating. Both ends of the outer side of the limiting insert 15 are fixedly connected to protruding plates 18. The protruding plates 18 facilitate the removal of the limiting insert 15 from the limiting groove 11. The rear outer wall of the air guide shroud 8 has multiple through holes 10 to allow the fan 12 to draw in air. When the fan 12 rotates, it draws air into the air guide shroud 8 through the through holes 10 and flows out between the air guide shroud 8 and the baffle ring 17, thus blowing the air towards the heat dissipation fins 6 to remove heat from the fins and achieve a cooling effect. A junction box 4 is fixedly connected to the front outer wall of the top of the motor body 1. The junction box 4 contains windings and terminals.

[0020] Working principle: When installing the air guide shroud 8, first open the two retaining rings 9, then install the air guide shroud 8 to the rear end of the motor body 1. Next, rotate the retaining rings 9 down so that they engage with the retaining grooves 14 on the outer wall of the air guide shroud 8, thus limiting the air guide shroud 8. Then, insert the limiting insert 15 into the limiting groove 11. During insertion, the two retaining rings 9 will expand the limiting insert 15 through the retaining block 3. When the limiting insert 15 is fully inserted, the retaining block 3 disengages from the retaining rings 9, and the limiting insert 15 returns to its original position, thus limiting the two retaining rings 9 and preventing them from rotating. This is also done when replacing the heat sink fins 6. First, the air guide shroud 8 needs to be removed. Then, the damaged heat sink fin 6 is pulled out, and the insert 16 on the new heat sink fin 6 is inserted into the slot 13. After that, the air guide shroud 8 is installed. After installation, the retaining ring 17 on the inner wall of the air guide shroud 8 will abut against the heat sink fin 6 from the rear end, thereby ensuring the stability of the heat sink fin 6. When the motor body 1 is working, the fan 12 will rotate. The rotation of the fan 12 will draw air into the air guide shroud 8 through the through hole 10 and flow out from between the air guide shroud 8 and the retaining ring 17, thereby blowing the air toward the heat sink fin 6 to remove the heat on the heat sink fin 6 and achieve the effect of heat dissipation.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
