DETAILED DESCRIPTION

[0020] 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. Example 1

[0021] See also Figure 1-4 The utility model provides the following technical solutions: a permanent magnet synchronous servo motor stator structure, including a stator body 1, an assembly structure 2 is provided on the inner surface of the stator body 1, a stator device 3 is provided on the inner surface of the assembly structure 2, an assembly groove 4 is provided on one side of the interior of the stator body 1, a heat dissipation component 5 is provided on the other side of the interior of the stator body 1, and a shock absorption component 6 is provided on the surface of the stator body 1.

[0022] Specifically, the heat dissipation assembly 5 includes a support plate 51, heat dissipation fins 52, a fixed shaft 53, a baffle 54 and a fixing screw 55, wherein a support plate 51 is provided on the other side of the interior of the stator body 1, and the heat dissipation fins 52 are provided inside the support plate 51. A fixed shaft 53 is provided on one side of the stator body 1, and a baffle 54 is provided on the surface of the fixed shaft 53, and a fixing screw 55 is provided inside the baffle 54.

[0023] By adopting the above technical solution, when installing the heat dissipation component 5, the heat dissipation fins 52 are fixed to the inside of the support plate 51, the support plate 51 is inserted into the inside of the stator body 1, and the baffle 54 is rotated so that the baffle 54 rotates around the fixed axis 53 to one side of the support plate 51, and the baffle 54 is fixed with the fixing screw 55. At this time, the servo motor starts to work, and the heat generated by the servo motor is transferred to the inside of the stator body 1. The heat is transferred from the inside of the stator body 1 to the support plate 51, and the support plate 51 transfers the internal heat to the heat dissipation fins 52. The heat dissipation fins 52 use air circulation to dissipate the heat into the air, thereby achieving heat dissipation of the stator structure, ensuring that the temperature of the stator structure remains stable, and preventing the servo motor from overheating due to excessive temperature, thereby reducing its service life.

[0024] Specifically, clamping blocks are symmetrically provided on both sides of the support plate 51 , and a pulling block is provided on the other side of the support plate 51 .

[0025] By adopting the above technical solution, when removing the heat sink 52, rotate the fixing screw 55 to separate the fixing screw 55 from the baffle 54, and rotate the baffle 54 to make the baffle 54 away from the block on the side of the support plate 51. At this time, the staff can pinch the pulling block with their hands and pull it outward to pull out the support plate 51, making it easier for the staff to disassemble and install the heat sink fins 52.

[0026] When using this embodiment: fix the heat dissipation fins 52 inside the support plate 51, insert the support plate 51 into the interior of the stator body 1, rotate the baffle 54, rotate the baffle 54 around the fixed axis 53 to one side of the support plate 51, and fix the baffle 54 with the fixing screw 55. At this time, the servo motor starts to work, and the heat generated by the servo motor is transferred to the interior of the stator body 1. The heat is transferred from the interior of the stator body 1 to the support plate 51. The support plate 51 transfers the internal heat to the heat dissipation fins 52, and the heat dissipation fins 52 utilizes air circulation to dissipate heat into the air, thereby achieving heat dissipation of the stator structure, ensuring that the temperature of the stator structure remains stable, preventing the servo motor from overheating due to excessive temperature, and reducing its service life. When disassembling and assembling the heat dissipation fins 52, rotate the fixing screws 55 to separate the fixing screws 55 from the baffle 54, and rotate the baffle 54 to move the baffle 54 away from the block on one side of the support plate 51. At this time, the staff can pinch the pulling block with their hands and pull it outward to pull out the support plate 51, making it easier for the staff to disassemble and assemble the heat dissipation fins 52. Example 2

[0027] The difference between this embodiment and embodiment 1 is that: specifically, the shock absorbing assembly 6 includes a fixing plate 61, a cylinder 62, a spring 63, a damping block 64, a fixing groove 65 and a fixing ring 66, wherein a fixing plate 61 is provided on the surface of the stator body 1, a cylinder 62 is provided at the lower end of the fixing plate 61, a spring 63 is provided inside the cylinder 62, a fixing groove 65 is provided at the lower end of the spring 63, a damping block 64 is provided inside the fixing groove 65, and a fixing ring 66 is provided at the lower end of the fixing groove 65.

[0028] By adopting the above technical solution, when the stator structure is subjected to vibration, the pressure is transmitted to the spring 63 through the fixing plate 61, causing the spring 63 to shrink and deform into the fixing groove 65. At the same time, the fixing plate 61 pushes the cylinder 62 to move into the fixing groove 65. The surface of the cylinder 62 and the damping block 64 inside the fixing groove 65 produce friction, so that the elastic potential energy of the spring 63 is converted into friction between the cylinder 62 and the damping block 64, and the pressure caused by the vibration is offset. When the spring 63 rebounds, the spring 63 pushes the fixing plate 61 to return to its original position. At the same time, the surface of the cylinder 62 and the damping block 64 produce friction. The elastic potential energy of the spring 63 is converted into friction between the cylinder 62 and the damping block 64 and weakened, so that the spring 63 pushes the fixing plate 61 to slowly return to its original position, thereby ensuring the stability of the stator structure, preventing damage to parts inside the stator structure due to vibration, and reducing the maintenance cost of the stator structure.

[0029] Specifically, a fixing block is provided on one side of the surface of the stator body 1 , an elastic supporting block is provided on one side of the fixing block, and one end of the elastic supporting block is provided in the shape of a hemisphere.

[0030] By adopting the above technical solution, when the stator structure is vibrated, the elastic support block can share part of the pressure, which is beneficial to reducing the pressure on the spring 63. One end of the elastic support block is set as a hemisphere to better disperse the pressure, thereby improving the load-bearing effect of the elastic support block.

[0031] Specifically, an insulating gasket is provided on the surface of the fixing ring 66 , and the fixing ring 66 and the insulating gasket are bonded together by high-temperature resistant glue.

[0032] By adopting the above technical solution, when the servo motor is working, the insulating gasket on the surface of the fixing ring 66 provides isolation, preventing the hidden dangers caused by the fixing ring 66 being conductive, and improving the safety of the structure.

[0033] When this embodiment is in use, the pressure is transmitted to the spring 63 through the fixing plate 61, causing the spring 63 to shrink and deform into the fixing groove 65. At the same time, the fixing plate 61 pushes the cylinder 62 to move into the fixing groove 65. The surface of the cylinder 62 and the damping block 64 inside the fixing groove 65 produce friction, so that the elastic potential energy of the spring 63 is converted into friction between the cylinder 62 and the damping block 64. The pressure caused by the vibration is offset. When the spring 63 rebounds, the spring 63 pushes the fixing plate 61 to return to its original position. At the same time, the surface of the cylinder 62 and the damping block 64 produce friction, and the elastic potential energy of the spring 63 is converted into friction between the cylinder 62 and the damping block 64. The friction is weakened, so that the spring 63 pushes the fixed plate 61 to slowly return to its original position, thereby ensuring the stability of the stator structure, preventing the internal parts of the stator structure from being damaged due to vibration, and reducing the maintenance cost of the stator structure. When the stator structure is vibrated, the elastic support block can share part of the pressure, which is beneficial to reducing the pressure on the spring 63. One end of the elastic support block is set to be a hemisphere to better disperse the pressure and improve the load-bearing effect of the elastic support block. When the servo motor is working, the insulating gasket on the surface of the fixing ring 66 provides isolation to prevent the hidden dangers of the fixing ring 66 caused by conductivity, thereby improving the safety of the structure.

[0034] The damping block 64 in the present invention is an existing disclosed technology, and the selected model is GBZY.

[0035] The structure and usage principle of the stator body 1, assembly structure 2, stator device 3 and assembly slot 4 in the present invention have been disclosed in a permanent magnet synchronous servo motor stator structure disclosed in Chinese patent application No. 202222089559.9.

[0036] The working principle and use process of the present invention are as follows: when the stator structure of the permanent magnet synchronous servo motor is in use, the servo motor starts working, and the heat generated by the servo motor is transferred to the inside of the stator body 1. The heat is transferred from the inside of the stator body 1 to the support plate 51, and the support plate 51 transfers the internal heat to the heat dissipation fins 52. The heat dissipation fins 52 use air circulation to dissipate the heat into the air, thereby achieving heat dissipation of the stator structure, effectively reducing the temperature of the stator structure, and preventing the servo motor from overheating due to excessive temperature, thereby reducing the service life. When disassembling and assembling the heat dissipation fins 52, rotate the fixing screw 55 to separate the fixing screw 55 from the baffle 54, and rotate the baffle 54 to make the baffle 54 away from the block on one side of the support plate 51. At this time, the staff can pinch the pulling block by hand and pull outward to pull out the support plate 51, making it easier for the staff to disassemble and assemble the heat dissipation fins 52. When the stator structure is vibrated, the pressure is transferred to the spring 63 through the fixing plate 61, causing the spring 63 to shrink and deform into the inside of the fixing groove 65. At the same time, the fixing plate 61 pushes the cylinder 62 toward the fixing groove 65 During internal movement, the surface of the cylinder 62 and the damping block 64 inside the fixed groove 65 produce friction, which converts the elastic potential energy of the spring 63 into friction between the cylinder 62 and the damping block 64, and the pressure caused by the vibration is offset. When the spring 63 rebounds, the spring 63 pushes the fixed plate 61 back to its original position. At the same time, the surface of the cylinder 62 and the damping block 64 produce friction, and the elastic potential energy of the spring 63 is converted into friction between the cylinder 62 and the damping block 64 and weakened, so that the spring 63 pushes the fixed plate 61 to slowly return to its original position, thereby ensuring the stability of the stator structure, preventing damage to parts inside the stator structure due to vibration, and reducing the maintenance cost of the stator structure. When the stator structure is subjected to vibration, the elastic support block can share part of the pressure, which is conducive to reducing the pressure on the spring 63. One end of the elastic support block is set as a hemisphere to better disperse the pressure and improve the load-bearing effect of the elastic support block. When the servo motor is working, the insulating gasket on the surface of the fixing ring 66 provides isolation, preventing the hidden dangers caused by the conductive conduction of the fixing ring 66, and improving the safety of the structure.
