[0028] As shown in Figs. 1-4 The motor pressing and sealing device provided by the embodiment includes a bottom plate 100, a positioning mechanism 200 and a sealing cover mechanism 300. The positioning mechanism 200 is rotationally connected with the bottom plate 100. The motor to be sealed 600 is placed at the center of the positioning mechanism 200. After the positioning mechanism 200 rotates relative to the bottom plate 100, the motor to be sealed 600 can be automatically centered and clamped. The sealing cover mechanism 300 penetrates the periphery of the positioning mechanism 200 and abuts against the motor to be sealed 600. The sealing cover mechanism 300 is used for riveting and pressing the motor to be sealed 600. By placing the motor to be sealed 600 at the center of the positioning mechanism 200, and adjusting the center positions of the positioning mechanism 200 and the motor to be sealed 600, the motor to be sealed 600 can be accurately clamped at the center position of the positioning mechanism 200, so as to ensure that, during the riveting and pressing process, the sealing cover mechanism 300 can uniformly abut against the motor to be sealed 600 because the sealing cover mechanism 300 penetrates the periphery of the positioning mechanism 200. During the riveting and pressing process, the riveting and pressing force can be accurately applied, so as to improve the sealing effect.

[0029] Specifically, the positioning mechanism 200 in the embodiment includes a base plate 210, a chuck 220, a positioning rotary body 240, and a plurality of clamping assemblies 250. The base plate 210 is mounted on the base plate 100. The chuck 220 is sleeved on the positioning rotary body 240. The positioning rotary body 240 is provided with a through hole 241 for accommodating the motor to be sealed 600. The side wall of the positioning rotary body 240 is provided with a plurality of avoiding holes 242. The plurality of clamping assemblies 250 pass through the avoiding holes 242 to clamp the motor to be sealed 600. The chuck 220 is provided with a plurality of eccentric circular grooves 230. The clamping assemblies 250 are connected with the eccentric circular grooves 230. The eccentric circular grooves 230 can guide the clamping assemblies 250 to move towards or away from the center of the positioning rotary body 240 to clamp or loosen the motor to be sealed 600. Through such a design, the plurality of clamping assemblies 250 can be distributed in the circumferential direction of the positioning rotary body 240, so as to clamp the motor to be sealed 600 from multiple positions. On the one hand, the stability of clamping the motor to be sealed 600 can be improved. On the other hand, the accuracy of the centering of the motor to be sealed 600 can be improved. The eccentric circular grooves 230 are arranged to guide the clamping assemblies 250 to move towards or away from the center of the positioning rotary body 240 to clamp or loosen the motor to be sealed 600. Through the design of the positioning mechanism 200, the motor to be sealed 600 can be accurately placed at the center position of the positioning rotary body 240, so as to ensure the accuracy of the sealing position. The design of the plurality of clamping assemblies 250 can reliably clamp the motor to be sealed 600, so as to avoid problems such as position deviation or sliding during the sealing process. The position of the eccentric circular groove 230 is adjusted to control the movement of the clamping assembly 250. The operation is simple and convenient. At the same time, it can be applied to motors of various models and sizes, so as to improve the universality and production efficiency of the production line.

[0030] Further, the clamping assembly 250 in the embodiment includes a clamping part 251 and a guide column 252. The guide column 252 is arranged in the eccentric circular groove 230. The clamping part 251 is arranged in the radial direction of the positioning rotary body 240. The clamping part 251 is connected with the guide column 252. When the guide column 252 moves in the eccentric circular groove 230, the guide column 252 drives the clamping part 251 to move towards or away from the motor to be sealed 600. The movement of the guide column 252 can guide the clamping part 251 to move towards or away from the motor to be sealed 600, so as to achieve the purpose of clamping or loosening the motor to be sealed 600. Through the arrangement of the eccentric circular groove 230 and the guide column 252 on the positioning rotary body 240, the radial movement of the clamping assembly 250 is realized, so as to flexibly control the distance between the clamping part 251 and the motor to be sealed 600. In this way, the distance between the clamping part 251 and the motor to be sealed 600 can be adjusted according to motors of different sizes and shapes. The pressure applied to the motor during the clamping process is uniformly distributed, so as to avoid damage or deformation of the motor.

[0031] Preferably, the clamping part 251 in this embodiment is arc-shaped on the side facing the motor 600 to be sealed. By so arranging, the arc-shaped clamping part 251 can conform to the motor 600 to be sealed, increasing the contact area between the clamping part 251 and the motor 600 to be sealed, thereby improving the firmness of clamping, ensuring that the clamping part 251 does not slip or shift, and ensuring the quality and stability of the sealing. The arc-shaped clamping part 251 can better adapt to the curved shape of the motor 600 to be sealed, avoiding the generation of gaps or deformation between the clamping part 251 and the motor, thereby preventing the risk of damage to the motor during clamping and pressing. The arc-shaped clamping part 251 can uniformly distribute pressure during clamping and pressing, avoiding the risk of local excessive pressure causing deformation or damage to the motor, thereby improving the uniformity and stability of the sealing.

[0032] Further, the chassis 210 in this embodiment is provided with a plurality of wedge blocks 211, and the clamping assembly 250 further comprises a connecting part 253, the bottom end of the connecting part 253 is provided with a spherical ball 2531, the spherical ball 2531 abuts against the wedge block 211, and the connecting part 253 can move vertically when the spherical ball 2531 moves relative to the wedge block 211. The plurality of wedge blocks 211 can make the vertical movement of the clamping assembly 250 more stable, thereby improving the working efficiency and precision of the device. The abutment of the spherical ball 2531 at the bottom end of the connecting part 253 and the wedge block 211 can reduce wear caused by friction during vertical movement, thereby prolonging the service life of the device. When the connecting part 253 moves vertically, the distance and contact force between the clamping assembly 250 and the motor 600 to be sealed can be adjusted more flexibly, thereby meeting the needs of motors 600 to be sealed of different sizes and shapes.

[0033] Further, the cover mechanism 300 in this embodiment is provided in plurality, and the plurality of cover mechanisms 300 can abut against the motor 600 to be sealed through the plurality of avoiding holes 242 and perform riveting and pressing sealing on the motor 600 to be sealed. Due to the increase in the number of cover mechanisms 300, the plurality of positions of the motor 600 to be sealed can be simultaneously subjected to riveting and pressing sealing, thereby improving the efficiency and speed of sealing. Due to the plurality of cover mechanisms 300, they can correspond to different sealing positions respectively, thereby reducing the risk of inaccurate riveting and pressing caused by errors. By providing the plurality of avoiding holes 242, the cover mechanisms 300 can abut against different positions of the motor 600 to be sealed, thereby increasing the applicability and versatility of the positioning rotary body 240.

[0034] Specifically, each of the cover mechanisms 300 in the embodiment includes an upper cover knife 310, a lower cover knife 320, a cover knife seat 330, and a first driving member 340. The upper cover knife 310 and the lower cover knife 320 are sequentially arranged on the same side of the cover knife seat 330 along the vertical direction, and are arranged to abut against the motor 600 to be sealed through the avoiding hole 242. The first driving member 340 is installed on the cover knife seat 330, and the output end of the first driving member 340 is connected with the upper cover knife 310 and the lower cover knife 320 respectively. The first driving member 340 is used to drive the upper cover knife 310 and the lower cover knife 320 to rivet and press seal the motor 600 to be sealed. The rivet and press sealing of the motor 600 to be sealed by the upper cover knife 310 and the lower cover knife 320 can ensure the tightness and reliability of the sealing. At the same time, the upper cover knife 310 and the lower cover knife 320 are sequentially arranged on the same side of the cover knife seat 330 along the vertical direction, which can improve the compactness and stability of the device.

[0035] Preferably, the first driving member 340 in the embodiment is an oil cylinder. The oil cylinder has large driving force, which can meet the high-strength pressing and sealing of the motor 600 to be sealed, thereby ensuring the quality of the product. The oil cylinder has the characteristics of fast response speed, good stability, low noise, etc., which can meet the efficient and stable production demand. The oil cylinder has simple structure, convenient maintenance, and is not easy to malfunction, which can improve the production efficiency and reduce the maintenance cost. Using the oil cylinder as the driving member can improve the working efficiency and stability of the motor pressing and sealing device 600 to be sealed, and reduce the maintenance cost, which helps to improve the product quality and production efficiency.

[0036] Further preferably, the motor pressing and sealing device in the embodiment further includes an auxiliary limiting mechanism 400. The auxiliary limiting mechanism 400 includes a guide rod 410 and a pressure head assembly 420. The pressure head assembly 420 can move downward along the guide rod 410 and abut against the top of the motor 600 to be sealed. The auxiliary limiting mechanism 400 provides additional positioning support to help ensure the correct position and direction of the motor 600 to be sealed during sealing, thereby improving the accuracy and success rate of sealing. The guide rod 410 provides a guiding effect for the pressure head assembly 420 to ensure the accuracy of the downward pressure of the pressure head assembly 420. The pressure head assembly 420 abutting against the top of the motor 600 to be sealed can assist in positioning the motor 600 to be sealed for rivet and press sealing, further improving the accuracy.

[0037] Further preferably, the motor pressing and sealing device in the embodiment further comprises a material returning mechanism 500, which comprises a bracket 510, a material returning rod 520 and a second driving member 530. The bracket 510 is installed at the bottom of the bottom plate 100, the material returning rod 520 can abut against the motor to be sealed 600, and the second driving member 530 is installed on the bracket 510 and connected with the material returning rod 520 at the output end, and is used to drive the material returning rod 520 to move. The material returning mechanism 500 in the embodiment is used to move the motor with completed sealing out of the sealing area. The material returning mechanism 500 comprises the bracket 510, the material returning rod 520 and the second driving member 530. The bracket 510 is installed at the bottom of the bottom plate 100, the material returning rod 520 can abut against the motor to be sealed 600, and the second driving member 530 is installed on the bracket 510 and connected with the material returning rod 520 at the output end, and is used to drive the material returning rod 520 to move. Through this mechanism, the motor with completed sealing can be quickly and conveniently moved out of the sealing area, thereby providing space and convenience for the next operation. The motor with completed sealing can be quickly moved out through the material returning mechanism 500, thereby providing convenience for the next operation and improving the production efficiency. The traditional sealing device needs to manually move the motor with completed sealing out of the sealing area, which is tedious and prone to errors. Through the material returning mechanism 500, the motor with completed sealing can be automatically moved out, thereby reducing manual operation and improving the production efficiency. Since the material returning mechanism 500 can accurately move the motor with completed sealing, the sealing precision can be better controlled, and the product quality can be improved.
