Description

Technical Field

[0001] The present invention belongs to the field of servo motors, and particularly relates to a servo motor with a protection structure. Background Art

[0002] With the development of industrial technology, modern servo motor technology has become more and more perfect. Servo motors need to work properly in a stable environment, so a protective shell needs to be installed outside the servo motor. However, an overly tight protective shell will affect the heat dissipation effect.

[0003] For example, a servo motor with a protection structure disclosed in Patent No. 202210710652.9, which relates to the technical field of drive motors, includes a motor body assembly, a heat dissipation and cooling assembly, and a rotation speed detection assembly; the heat dissipation and cooling assembly includes a rear inner ratchet, a rear outer ratchet, a front inner ratchet, a front outer ratchet, a rear gear set, an outer end tooth ring, a large gear, and a rear heat dissipation fan. The rear gear set, the outer end tooth ring, and the large gear are all rotatably installed on the rear machine base. The rear inner ratchet and the front inner ratchet are stacked and fixedly installed on the motor shaft. The rear inner ratchet meshes with the rear outer ratchet. The input end of the rear gear set forms a gear fit with the rear outer ratchet, and the output end of the rear gear set forms a gear fit with the outer end tooth ring; the rear heat dissipation fan is fixedly connected to the outer end tooth ring and can rotate together with the outer end tooth ring. The rotation of the rear heat dissipation fan reduces the temperature of the motor in the actual power environment, increases the threshold of demagnetization, and reduces the occurrence of demagnetization.

[0004] This device still has defects when in use. First, the protective shell of this device is very tight. The overly tight protective shell increases the heat dissipation of the servo motor, and the overly tight protective shell will also affect subsequent disassembly and maintenance. The too high temperature of the servo motor will affect the normal operation of the equipment. Second, the protection structure of this device is difficult to adjust. If the servo motor needs to be installed in different environments, the servo motor requires different anti-vibration effects. Summary of the Invention

[0005] The purpose of the present invention is to provide a servo motor with a protection structure in view of the deficiencies of the prior art. When this device is in use, when the protective shell and the servo motor inside it are shaken, the pulling springs on both sides of the protective shell will absorb the shaking. The four support frames and rubber tiles on the outside of the inner shell increase the effect of absorbing the shaking. During the adjustment of the device, the bolt rod on the elastic slider is rotated and loosened, and the elastic slider can move outwards along the elastic guide rail for a certain distance and then lock the bolt rod again. Thus, the two pulling springs can be stretched longer, increasing the anti-shaking effect and achieving the effect of portable debugging equipment, so as to solve the problems mentioned in the background art.

[0006] To solve the above problems, the present invention provides the following technical solutions: A servo motor with a protective structure, including a base plate, on the top of the base plate is provided a protective shell, at the bottom of the protective shell are provided two stabilizing platforms, the stabilizing platforms are attached to the top surface of the base plate, and on the outer side of the protective shell are provided several heat dissipation fins arranged in a circular array; on both sides of the protective shell are provided elastic mechanisms; inside the protective shell is provided an inner shell, inside the inner shell is provided a servo motor, and between the protective shell and the inner shell is provided a stabilizing structure; the stabilizing mechanism includes a support frame on the outer side wall of the inner shell, at the end of the support frame is provided a rubber tile, and the rubber tile is fixedly connected to the inner side wall of the protective shell through bolts; on the servo motor is also provided a heat exchange structure.

[0010] Further, the elastic mechanism includes a groove on the top of the base plate, inside the groove is installed a stabilizing box body, the material of the stabilizing box body is plastic, and inside the stabilizing box body is provided a partition, the partition separates the large chamber inside the stabilizing box body into several small chambers arranged in a rectangular array, and on the side wall of each small chamber is provided a plunger hole, inside the plunger hole is provided a plunger, and between the stabilizing box body and the stabilizing platform is connected through a bolt assembly.

[0011] Further, the bolt assembly includes a threaded hole on the side wall of the stabilizing platform, and between the threaded hole and the stabilizing box body is connected through a threaded pin rod.

[0014] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects:

[0015] Firstly, when the protective housing and the servo motor inside it are shaken, the tension springs on both sides of the protective housing will absorb the shaking.

[0016] Secondly, the heat generated by the servo motor is first transferred to the aluminum box. The aluminum box transports the heat-conducting liquid to the heat exchange coil through the infusion hose, and the heat exchange coil then transfers the heat to the protective housing for heat dissipation operation. While serving as a protective housing, the protective housing can also serve as a heat dissipation structure, achieving the effect that the same component can perform multiple functions.

Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0029] The present invention provides a servo motor with a protection structure, as Figure 1-8 shown, including a base plate 1, a protective housing 4 is provided at the top of the base plate 1, two stable platforms 5 are provided at the bottom of the protective housing 4, the stable platforms 5 are attached to the top surface of the base plate 1, and a plurality of annularly arrayed heat dissipation fins are provided on the outer side of the protective housing 4; elastic mechanisms are provided on both sides of the protective housing 4; an inner shell 6 is provided inside the protective housing 4, a servo motor 7 is provided inside the inner shell 6, and a stabilizing structure is provided between the protective housing 4 and the inner shell 6; the stabilizing mechanism includes a support frame 601 on the outer side wall of the inner shell 6, a rubber tile 602 is provided at the end of the support frame 601, and the rubber tile 602 is fixedly connected to the inner side wall of the protective housing 4 by bolts; a heat exchange structure is also provided on the servo motor 7.

[0030] In this embodiment, the four support frames 614 and rubber tiles 602 on the outer side of the inner shell 6 increase the effect of absorbing vibrations. While the protective housing 4 serves as a protective device, the protective housing 4 can also serve as a heat dissipation structure, increasing the functionality of the components.

[0031] In a further embodiment of the present invention, asFigure 1-3 As shown, a layer of sheet metal material is laid on the top surface of the protective housing 4. The stabilizing table 5 is made of wear-resistant alloy steel, and machine oil is applied between the protective housing 4 and the stabilizing table 5.

[0033] In a further embodiment of the present invention, as Figure 1-3 shown, the elastic mechanism includes two guide rail grooves 101 at the top end of the base plate 1.

[0036] In this embodiment, when the bolt rod on the elastic slider 201 is rotated and loosened, the elastic slider 201 can move outwards along the elastic guide rail 2 for a certain distance and then lock the bolt rod again. Thus, the two pulling springs 3 can be stretched longer, increasing the anti-shaking effect and achieving the effect of portable debugging equipment.

[0037] In a further embodiment of the present invention, as Figure 1-6 shown, the elastic mechanism includes a groove at the top end of the base plate 1. A stabilizing box body 8 is installed in the groove. The stabilizing box body 8 is made of plastic. A separator is arranged inside the stabilizing box body 8. The separator separates the large chamber inside the stabilizing box body 8 into several small chambers in a rectangular array. A plunger hole is arranged on the side wall of each small chamber, and a plunger is arranged inside the plunger hole. The stabilizing box body 8 and the stabilizing table 5 are connected by a bolt assembly.

[0038] In this embodiment, high-pressure air is charged into the stabilizing box body 8. The stabilizing box body 8 is divided into several small chambers in a rectangular array.

[0039] In a further embodiment of the present invention, as Figure 1-6 shown, the bolt assembly includes a threaded hole 403 on the side wall of the stabilizing platform 5, and the threaded hole 403 and the stabilizing box body 8 are connected by a threaded pin rod.

[0040] In this embodiment, the stabilizing platform 5 is connected to the stabilizing box body 8 through a bolt pin rod, and after the stabilizing box body 8 is damaged, it can be disassembled for maintenance.

[0041] In a further embodiment of the present invention, as Figure 1-3 shown, the heat exchange structure includes a heat exchange coil 401 on the inner side wall of the protective housing 4, a spiral groove matching the heat exchange coil 401 is provided on the inner side wall of the servo motor 7, a heat dissipation rectangular groove is provided on the side wall of the servo motor 7, an aluminum box 701 is provided inside the heat dissipation rectangular groove, an internal pump is provided inside the aluminum box 701, both ends of the heat exchange coil 401 are provided with infusion hoses 402, and the two infusion hoses 402 are connected to the internal pump inside the aluminum box 701.

[0042] In this embodiment, the heat generated by the servo motor 7 is first transferred to the aluminum box 701, and the aluminum box 701 transports the heat-conducting liquid to the heat exchange coil 401 through the infusion hose 402, and then the heat exchange coil 401 transfers the heat to the protective housing 4 for heat dissipation operation.

[0043] In a further embodiment of the present invention, as Figure 1-8 shown, the heat exchange structure includes a heat dissipation rectangular groove at the rear end of the servo motor 7, a heat exchange box 10 is provided inside the heat dissipation rectangular groove, the heat exchange box 10 is attached to the inner side wall of the heat dissipation rectangular groove through a heat exchange copper plate 1001, an internal pump is provided inside the heat exchange box 10, a plurality of surrounding pipes 9 are connected to the internal pump, and heat exchange wire grooves matching the surrounding pipes 9 are provided on the inner side wall of the protective housing 4.

[0044] In this embodiment, the heat generated by the servo motor 7 is first transferred to the heat exchange box 10, and the heat exchange box 10 transfers the heat to the protective housing 4 through the surrounding pipes 9 for heat dissipation operation.

[0045] Working principle: The four support frames 614 and the rubber tiles 602 on the outer side of the inner shell 6 enhance the effect of absorbing vibrations. While serving as a protective device, the protective outer shell 4 can also function as a heat dissipation structure, increasing the functionality of the components. When the device is shaken, intense friction occurs between the protective outer shell 4 and the stabilizing platform 5. The wear-resistant alloy steel enhances the abrasion resistance of the device. The tension springs 3 on both sides of the protective outer shell absorb vibrations. The protective outer shell 4 will have a slight slide on the elastic guide rail 2. During the sliding process of the protective outer shell 4, the two tension springs 3 store and release energy respectively. Loosen the bolt rod on the elastic slider 201, and the elastic slider 201 can move outward along the elastic guide rail 2 for a certain distance and then lock the bolt rod again. Thus, the two tension springs 3 can be stretched longer, enhancing the anti-vibration effect and achieving the effect of a portable debugging device. Charge high-pressure air into the stabilizing box body 8. The stabilizing box body 8 is divided into several small chambers in a rectangular array. When a certain small chamber in the stabilizing box body 8 is damaged, the stabilizing box body 8 can still operate normally. The stabilizing platform 5 is connected to the stabilizing box body 8 through bolt pins. After the stabilizing box body 8 is damaged, it can be disassembled for maintenance. The heat generated by the servo motor 7 is first transferred to the aluminum box 701. The aluminum box 701 transports the heat-conducting liquid to the heat exchange coil 401 through the infusion hose 402. The heat exchange coil 401 then transfers the heat to the protective outer shell 4 for heat dissipation operations. The heat generated by the servo motor 7 is first transferred to the heat exchange box 10. The heat exchange box 10 transfers the heat to the protective outer shell 4 through the surrounding pipe 9 for heat dissipation operations.
