Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and more specifically, to a motor stator mounting and positioning device. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. During the manufacturing process of an electric motor, it is often necessary to install the stator inside the motor housing. For example, a motor stator press-fitting device proposed in application number "CN202311440756.3" includes a base and a mounting platform on top of the base. The upper surface of the base has an assembly placement groove, and a pressure cylinder is fixedly installed on the top of the mounting platform. The motor housing is placed inside the assembly placement groove. The upper part is provided with a stator, and also with a pressing sleeve block that can squeeze the stator. The stator is also provided with several copper wire windings inside. A two-stage pressing assembly is provided between the output end of the pressure cylinder and the pressing sleeve block. The present invention, through the pressure cylinder and assembly placement groove designed with a coaxial axis, and the concave cavity and annular bottom designed at the bottom of the pressing sleeve block, can not only ensure that the copper wire windings are not damaged during the process of the pressure cylinder driving the two-stage pressing assembly to press down on the stator, but also link the positioning mechanism to clamp and fix the motor housing to ensure the stability of the pressing.

[0003] However, while the above technical solutions can ensure that the copper wire windings are not damaged during stator installation and that the overall pressing stability is guaranteed, it becomes extremely difficult to manually handle and place the motor housing or stator when it is heavy. This not only consumes a lot of manpower and time, but also makes it difficult to guarantee the stability during manual handling. Therefore, we propose a motor stator installation and positioning device to solve the above problems. Utility Model Content

[0023] like Figures 4 to 6As shown, in another embodiment of this utility model, a fixing block 406 is installed in the middle of the lower surface of the pressure plate 405. An extension rod 408 is fixedly installed at the lower end of the fixing block 406. The extension rod 408 is movably installed through the auxiliary hole 5. A connecting hole 410 is provided in the middle of the extension rod 408. Several grooves 409 are provided through the connecting hole 410. A lifting block 413 is movably installed in the middle of the grooves 409 respectively. Anti-slip pads are installed on the sides of the lifting blocks 413 that are far apart from each other. A movable frame 412 is movably installed at the upper end of the connecting hole 410 and the groove 409. The movable frame 412 is connected to the lifting block 413. A motor 407 is installed inside the fixing block 406. A lead screw 411 is movably installed through the connecting hole 410. The upper end of the lead screw 411 is connected to the output end of the motor 407. The body of the lead screw 411 is threaded through and installed in the auxiliary hole 5. Inside the movable frame 412, a first fixing rod 414 is fixedly installed at the interior of each end of the movable frame 412 near the lifting block 413. A second fixing rod 415 is fixedly installed at the lower end of the interior of the groove 409. A third fixing rod 416 is installed at the upper and lower ends of the interior of the lifting block 413 on the side that is close to each other. A transmission block 417 is movably installed at the upper and lower ends of the interior of the groove 409. The ends of the transmission blocks 417 that are close to each other are movably installed at the upper and lower ends of the interior of the lifting block 413. The rods of the third fixing rods 416 are movably installed through the interior of the transmission blocks 417. The upper end of the transmission block 417 located on the upper side is movably installed inside the movable frame 412. The rods of the first fixing rods 414 are movably installed through the interior of the transmission blocks 417. The rods of the second fixing rods 415 are movably installed through the lower end of the interior of the transmission block 417 located on the lower side.

[0024] After the motor housing and stator are moved to both sides of the processing table 1 by the conveying device, the electric slide rail 402 and the slider 403 control one end of the extension rod 408 to the upper end of the housing. Then, the hydraulic cylinder 404 pushes the pressure plate 405 and the extension rod 408 downward. After the extension rod 408 moves into the interior of the housing, the motor 407 drives the lead screw 411 to rotate. The lead screw 411 then controls the movable frame 412 to move downward through the thread. The movable frame 412 then cooperates with the transmission block 417. Pushing the lifting block 413 allows it to fit against the inner wall of the outer casing, forming a single unit. Then, the hydraulic cylinder 404 pulls the extension rod 408 and the outer casing upwards, allowing the lifting block 413 to work with the extension rod 408 to replace manual loading of the outer casing, placing it inside the placement slot 3. After placement, the motor 407 drives the lead screw 411 to reverse, causing the lead screw 411 to move the movable frame 412 upwards, thus separating the lifting block 413 from the outer casing. Then, the hydraulic cylinder 404 pulls the extension rod 408 out of the housing. The electric slide rail 402 and slider 403 then move the extension rod 408 to the upper end of the stator. The hydraulic cylinder 404 then pushes the extension rod 408 downwards. Once the extension rod 408 is inside the stator, the motor 407 drives the lead screw 411 to rotate. The lead screw 411 then controls the movable frame 412 to move downwards via a threaded connection. The movable frame 412 then works with the transmission block 417 to lift the block. 413 is pushed to make the lifting block 413 fit against the inner wall of the stator, thus forming a whole. Then, the hydraulic cylinder 404 pulls the extension rod 408 and the stator to move upward, so that the stator moves to the upper end of the housing, making the stator and the housing overlap vertically. Then, the hydraulic cylinder 404 pushes the pressure plate 405 and the extension rod 408 downward, so that the extension rod 408, together with the lifting block 413, drives the stator to be inserted into the housing. Then, the pressure plate 405 squeezes the stator to complete the installation of the stator.

[0025] The auxiliary hole 5 is used to assist the extension rod 408 in moving downwards when it drives the stator for installation, so as to avoid collision between the extension rod 408 and the lower inner surface of the placement groove 3 and improve the overall stability.

[0026] The working principle of this motor stator mounting and positioning device:

[0027] In use, firstly, the motor housing and stator are moved to both sides of the processing table 1 by the conveying device. Then, the electric slide rail 402 and the slider 403 control one end of the extension rod 408 to the upper end of the housing. Then, the hydraulic cylinder 404 pushes the pressure plate 405 and the extension rod 408 downward. After the extension rod 408 moves into the interior of the housing, the motor 407 drives the lead screw 411 to rotate. Then, the lead screw 411 controls the movable frame 412 to move downward through the thread. Then, the movable frame 412 cooperates with the transmission. Block 417 pushes the lifting block 413, causing it to fit against the inner wall of the outer casing, thus forming a single unit. Then, hydraulic cylinder 404 pulls the extension rod 408 and the outer casing upwards, allowing the lifting block 413 to work with the extension rod 408 to replace manual loading of the outer casing, placing it inside the placement slot 3. After the outer casing is placed, motor 407 drives the lead screw 411 to reverse, causing the lead screw 411 to move the movable frame 412 upwards, thus allowing the lifting block 413 and the outer casing to... Separation is performed, and then the hydraulic cylinder 404 pulls the extension rod 408 out of the housing. Then, the electric slide rail 402 and the slider 403 move the extension rod 408 to the upper end of the stator. Then, the hydraulic cylinder 404 pushes the extension rod 408 downward. After the extension rod 408 moves into the stator, the motor 407 drives the lead screw 411 to rotate. Then, the lead screw 411 controls the movable frame 412 to move downward through the thread. Then, the movable frame 412 cooperates with the transmission block 417 to align with the top. The lifting block 413 is pushed so that it fits against the inner wall of the stator, forming a single unit. Then, the hydraulic cylinder 404 pulls the extension rod 408 and the stator upward, moving the stator to the upper end of the housing so that the stator and the housing overlap vertically. Then, the hydraulic cylinder 404 pushes the pressure plate 405 and the extension rod 408 downward, so that the extension rod 408, together with the lifting block 413, drives the stator to be inserted into the housing. Finally, the pressure plate 405 squeezes the stator to complete the installation of the stator.

For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
