DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4 An improved servo motor shown in the figure comprises a motor body 1, and two sides of the motor body 1 are respectively provided with a front end cover 2 and a rear end cover 3, a rotating hole is opened on the side of the front end cover 2, and the output shaft of the motor body 1 is rotatably installed in the rotating hole, and the opposite sides of the front end cover 2 and the rear end cover 3 are jointly provided with a protective component, and the side of the front end cover 2 is clamped and installed with a protective cover 7 through four clamping components, and the clamping component comprises a pin block 8, and the pin block 8 is fixedly installed on the end of the protective cover 7, and a clamping groove is arranged on the top of the pin block 8, a pin hole is opened on the side of the front end cover 2, and a slide groove is opened on the top inner wall of the pin hole, and a trapezoidal clamping block 9 is slidably installed in the slide groove through a compression unit, and a disassembly unit matched with the trapezoidal clamping block 9 is arranged in the clamping groove, a heat dissipation component is arranged on the output shaft of the motor body 1, and a filter component is arranged on the side of the protective cover 7.

[0023] By means of the above structure, when in use, the motor body 1 drives the output shaft to rotate during operation, thereby driving the heat dissipation assembly to dissipate heat from the motor body 1. When the protective cover 7 needs to be disassembled, it is only necessary to drive the multiple trapezoidal blocks 9 to move synchronously away from the axis through the multiple disassembly units, thereby releasing the limit with the multiple card slots, and then pulling the protective cover 7 to realize the disassembly function of the protective cover 7. When installation is required, it is only necessary to align the multiple pin blocks 8 with the multiple pin holes and insert them, so that the multiple trapezoidal blocks 9 can be driven to move synchronously away from the axis under the extrusion action. When the pin blocks 8 move to a suitable position, the trapezoidal blocks 9 are driven to reset under the elastic action of the compression unit, so that the clamping function can be realized. With this arrangement, the installation and disassembly of the protective cover 7 are simple and convenient, and easy to operate in practice.

[0024] like Figure 1 As shown, the protection component includes a lower shell 4 and an upper shell 5. The two ends of the lower shell 4 are fixedly connected to the relative inner walls of the front cover 2 and the rear cover 3 respectively. The upper shell 5 is hingedly installed on the lower shell 4. The bottom inner walls of the lower shell 4 and the upper shell 5 are each provided with two threaded holes, and two limit bolts 6 are respectively threadedly installed in the four threaded holes. Nuts are threadedly arranged on the two limit bolts 6. The advantage of such a configuration is that by hingedly installing the upper shell 5 on the lower shell 4, the motor body 1 can be easily inspected and repaired.

[0025] Specifically, when a fault occurs in the motor body 1, the multiple limit bolts 6 are unscrewed, and then the upper shell 5 is flipped over to expose the motor body 1 to the outside, making it convenient for the staff to perform maintenance operations on the motor body 1. This arrangement not only simplifies the disassembly and installation operations, but also facilitates subsequent maintenance operations on the motor body 1, and is highly practical.

[0026] like Figure 4 As shown, the compression unit includes a guide shaft 10 and a compression spring 11. A guide hole is opened at the top of the trapezoidal block 9. One end of the guide shaft 10 is fixedly installed on the top inner wall of the slide groove, and the other end of the guide shaft 10 is slidably installed in the guide hole. One end of the compression spring 11 is fixedly installed on the top inner wall of the slide groove, and the other end of the compression spring 11 is fixedly installed on the top of the trapezoidal block 9. The advantage of such an arrangement is that, through the arrangement of the compression spring 11, when the squeezing effect on the trapezoidal block 9 is released, the elastic action of the compression spring 11 can drive the trapezoidal block 9 to achieve a reset function.

[0027] Specifically, when the pin block 8 moves horizontally, it first squeezes the trapezoidal block 9 to make it move away from the axis, and squeezes the compression spring 11. When the pin block 8 moves to a suitable position, the squeezing effect on the trapezoidal block 9 disappears, and the elastic action of the compression spring 11 can drive it to reset and cooperate with the card slot to realize the card connection function.

[0028] like Figure 4 As shown, the disassembly unit includes an extrusion plate 14, which is slidably installed in the card slot. An operating groove is provided on the peripheral outer wall of the protective cover 7, and an operating plate 12 is slidably installed in the operating groove. The operating plate 12 and the inner wall of the side close to each other are jointly provided with a through hole, and a sliding shaft 13 is slidably installed in the through hole. One end of the sliding shaft 13 is fixedly connected to the side of the extrusion plate 14, and the other end of the sliding shaft 13 is fixedly connected to the side of the operating plate 12. A reset element is provided on the side of the operating plate 12. The advantage of such a setting is that through the setting of the extrusion plate 14, the extrusion effect on the trapezoidal card block 9 can be achieved, thereby forcing it to move in a direction away from the axis center, thereby releasing the limiting function with the card slot.

[0029] Specifically, the sliding operation plate 12 drives the sliding shaft 13 and the squeezing plate 14 to move horizontally, so that the trapezoidal block 9 is squeezed by the squeezing plate 14 to move away from the axis, thereby releasing the clamping limit with the card slot, making it easier to remove the protective cover 7.

[0030] like Figure 4As shown, the reset element includes a reset spring 15, one end of which is fixedly mounted on the side of the operating panel 12, and the other end of the reset spring 15 is fixedly mounted on the inner wall of the side of the operating slot. The advantage of such an arrangement is that, through the arrangement of the reset spring 15, when the pressure on the operating panel 12 is released, the elastic action of the reset spring 15 can drive the operating panel 12 to achieve a reset function.

[0031] Specifically, when the squeezing action on the operating plate 12 is released, the operating plate 12 can be driven to move in the opposite direction under the elastic action of the reset spring 15 , thereby driving the sliding shaft 13 and the squeezing plate 14 to synchronously realize the reset function.

[0032] like Figure 4 As shown, the heat dissipation assembly includes a heat dissipation fan 16, which is fixedly sleeved on the output shaft of the motor body 1. A plurality of air inlet holes 17 are evenly provided on the side of the front end cover 2, and a plurality of air outlet holes 18 are evenly provided on the side of the rear end cover 3. The advantage of such an arrangement is that, through the arrangement of the heat dissipation fan 16 and the air inlet holes 17 and the air outlet holes 18, the heat dissipation of the motor body 1 can be achieved through the heat dissipation fan 16 when the motor body 1 is working.

[0033] Specifically, when the motor body 1 is working, the output shaft rotates, thereby driving the heat dissipation fan 16 to rotate synchronously. Through the cooperation of the air inlet 17 and the air outlet 18, the internal heat is quickly dissipated to improve the heat dissipation effect.

[0034] like Figure 4 As shown, the filter assembly includes two semicircular filter plates 20, and two semicircular grooves are provided on the outer wall of the peripheral side of the protective cover 7. The two semicircular filter plates 20 are slidably installed in the two semicircular grooves respectively. The sides of the two semicircular filter plates 20 are provided with fixing units, and the fixing units include fixing bolts 19. The side of the protective cover 7 is provided with a threaded groove, and the side of the semicircular filter plate 20 is provided with a mounting hole. The fixing bolts 19 are threadedly installed in the threaded groove and the mounting hole. The advantage of this arrangement is that through the arrangement of the two semicircular filter plates 20, foreign matter in the air can be filtered when the air is incoming to prevent it from entering the interior and causing damage to the components.

[0035] Specifically, when the cooling fan 16 rotates, it drives air into the protective cover 7. Under the action of the two semicircular filter plates 20, foreign matter in the air can be filtered to prevent foreign matter from entering the interior and causing damage to the components. Moreover, through the setting of two fixing bolts 19, the semicircular filter plate 20 can be easily disassembled, which is convenient for cleaning after long-term use.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
