Description

Technical Field

[0001] This utility model belongs to the field of motor stator technology, and more specifically, it relates to a motor stator that is easy to maintain and replace. Background Technology

[0002] The stator is an important component of an electric motor, usually referring to the stationary part. In contrast to the rotor, the stator is mainly composed of an iron core, windings, and other related components. Its function is to generate a magnetic field and supply the electromagnetic force required for the rotor to rotate.

[0003] Currently, some motor stators require heating the motor housing to expand during installation before installing the stator inside. After the motor housing cools down, the stator is locked inside. This process not only takes a lot of time to heat and cool down, but also makes it inconvenient to remove the stator when performing regular maintenance or replacement of the motor, thus reducing the convenience of the device.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a motor stator that is easy to maintain and replace, in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a motor stator that is easy to maintain and replace, achieved by the following specific technical means:

[0006] A motor stator that is easy to maintain and replace includes a stator body with several limiting grooves on its periphery, and a first pressure plate and a second pressure plate. The bottom end face of the first pressure plate is equipped with limiting blocks equal in number to the limiting grooves. The second pressure plate is connected to the bottom ends of the limiting blocks by bolts. One side of each limiting block is provided with a groove, and the bottom of the groove is rotatably connected to a positive and negative threaded screw. The two ends of the positive and negative threaded screw are threadedly connected to a pair of movable blocks. One side of each movable block is rotatably connected to a transmission rod via a shaft, and the other end of the transmission rod is rotatably connected to a connecting block via a shaft. A fixing block is installed on the other side of the pair of connecting blocks.

[0007] Furthermore, a rotating block is installed at the top of the positive and negative threaded screw, penetrating the upper end face of the first pressure plate.

[0008] Furthermore, the dimensions of the fixing block match the dimensions of the groove.

[0009] Furthermore, one side of the fixing block is provided with an anti-slip texture.

[0010] Furthermore, the size of the movable block matches the size of the groove.

[0011] Furthermore, the dimensions of the limiting block and the limiting groove are matched.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By using a combination of a rotating block, a positive and negative threaded screw, a movable block, a transmission rod, and a fixed block, once the stator is placed into the motor housing, the operator quickly rotates the rotating block with the aid of a tool. The rotating block drives the positive and negative threaded screw to rotate, which in turn drives a pair of movable blocks to move towards the center. The movable blocks then drive one end of a pair of transmission rods to move towards the center. As one end of the transmission rods moves towards the center, the other end of the transmission rods drives a connecting block to move out of the groove. The connecting block then drives the fixed block to move out of the groove and press against the inner wall of the motor housing, thus fixing the stator in place. Reversing the rotation of the rotating block allows for quick disassembly of the stator, thereby achieving the effect of rapid stator installation and disassembly, which improves work efficiency and the convenience of the device.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a motor stator that is easy to maintain and replace, including a stator body 1. The stator body 1 has a plurality of limiting grooves 101 on its periphery. It also includes a first pressure cover 2 and a second pressure cover 3. The bottom end face of the first pressure cover 2 is equipped with a number of limiting blocks 4 equal to the number of limiting grooves 101. The second pressure cover 3 is connected to the bottom end of the plurality of limiting blocks 4 by bolts. One side of the limiting block 4 is provided with a groove 401. The bottom of the groove 401 is rotatably connected to a positive and negative threaded screw 402. The two ends of the positive and negative threaded screw 402 are threadedly connected to a pair of movable blocks 403. One side of the movable block 403 is rotatably connected to a transmission rod 404 through a shaft. The other end of the transmission rod 404 is rotatably connected to a connecting block 405 through a shaft. The other side of the pair of connecting blocks 405 is equipped with a fixing block 406.

[0028] Among them, a rotating block 407 is installed at the top end of the positive and negative threaded screw 402 through the upper end face of the first pressure cover 2, and the positive and negative threaded screw 402 is driven to rotate by the rotating block 407.

[0029] The size of the fixing block 406 matches the size of the groove 401, and when the positive and negative threaded screw 402 rotates in opposite directions, it can control the fixing block 406 to move into the groove 401.

[0030] One side of the fixing block 406 is provided with anti-slip texture, which can increase friction and make the stator more stable.

[0031] The dimensions of the movable block 403 match the dimensions of the groove 401.

[0032] The dimensions of the limiting block 4 and the limiting groove 101 are matched.

[0033] The working principle of this embodiment:

[0034] First, insert several limiting blocks 4 into several limiting grooves 101. Then, fix the second pressure cover 3 to the bottom of several limiting blocks 4 with bolts. Then, install the stator into the motor housing. After the stator is placed into the motor housing, the operator uses a tool to quickly rotate the rotating block 407. The rotating block 407 drives the positive and negative threaded screw 402 to rotate. The positive and negative threaded screw 402 drives a pair of movable blocks 403 to move towards the center. The pair of movable blocks 403 drives one end of a pair of transmission rods 404 to move towards the center. During the process of one end of the pair of transmission rods 404 moving towards the center, the other end of the pair of transmission rods 404 drives the connecting block 405 to move out of the groove 401. The connecting block 405 drives the fixing block 406 to move out of the groove 401 and presses against the inner wall of the motor housing, so that the stator is fixed.

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
