Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of three-phase asynchronous motors, in particular to a fixing device for production and processing of three-phase asynchronous motors. Background Art

[0002] The three-phase asynchronous motor is a commonly used AC motor, also known as an induction motor. The three-phase asynchronous motor is a type of motor that is powered by simultaneously connecting to a 380V three-phase AC current with a phase difference of 120 degrees. Since the rotor and stator rotating magnetic fields of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor. The three-phase asynchronous motor needs to be clamped and fixed during the production and processing process.

[0003] A new type of clamping mechanism for the production of three-phase asynchronous motors with publication number CN217883144U is disclosed. When the bottom of the engine casing is placed on two pads, one hand is used to hold the casing first, and the other hand is used to grasp the crank to rotate it. When the crank rotates, it will drive the rotating part to rotate. When the rotating part rotates, it will drive the bidirectional screw to rotate together with the cooperation of the bearing. It can avoid obstruction after clamping, improve the integrity of the outer surface painting, reduce the workload of the staff, and improve the painting efficiency. At the same time, by extending the hand into the fixed frame and holding the handle and rotating it clockwise, the handle will drive the threaded rod to rotate clockwise with the cooperation of the threaded groove when it rotates clockwise, so as to realize the function of height adjustment. It is suitable for operation by staff of different heights, improves the comfort of the staff, and is highly practical.

[0004] However, the above scheme requires manual operation during the clamping and fixing process, which is not convenient enough, has low flexibility, is not conducive to improving production efficiency, and is not comprehensive enough. Therefore, in view of this, research and improvement are conducted on the existing structure and deficiencies, and a fixing device for the production and processing of three-phase asynchronous motors is proposed.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0023] Combination Figure 1-Figure 4 The utility model is a fixing device for the production and processing of a three-phase asynchronous motor, comprising a workbench 1, two clamping plates 2 are placed on the top of the workbench 1, the two clamping plates 2 are connected to a driving assembly 3, the driving assembly 3 comprises a gear 301 rotatably connected to the top of the workbench 1, two sides of the gear 301 are respectively meshed with a rack 302, the rack 302 is fixed on a bar 303, the bar 303 is slidably connected to two mounting blocks 305, and one end of one bar 303 passes through the clamping plate 2 and is fixed on one side thereof, and the other bar 303 passes through the two clamping plates 2 and is fixed on the outside thereof.

[0024] Specifically, in this case, when in use, the three-phase asynchronous motor is placed between two clamps 2, driving the clamp 2 on the side close to the driving component 3 to move inward, and the clamp 2 drives the bar 303 to slide on the mounting block 305, and the rack 302 on the bar 303 moves accordingly, driving the gear 301 to rotate, and the rack 302 on the other side of the gear 301 is driven accordingly, and moves in the opposite direction to the rack 302 on the other side, and the rack 302 drives the bar 303 to slide on the mounting block 305, and the clamp 2 connected to the bar 303 also moves accordingly. In this process, the two clamps 2 move relative to each other, and the three-phase asynchronous motor is automatically corrected and clamped. The component has a simple structure and is easy to use, can meet the production needs of different motors, and improves production efficiency and flexibility.

[0025] Combination Figure 2-Figure 3A plurality of clamping blocks 5 are arranged in a matrix on the clamping plate 2, and the clamping blocks 5 are connected to the clamping plate 2 via springs 501. During the clamping process of the clamping plate 2, the clamping blocks 5 arranged in a matrix on the clamping plate 2 fix the three-phase asynchronous motor, and the springs 501 connected between the clamping blocks 5 and the clamping plate 2 are compressed to adapt to the outer surface of the three-phase asynchronous motor. The elastic force generated by the springs 501 makes it more convenient and stable for the clamping blocks 5 to fix the three-phase asynchronous motor.

[0026] The clamping surface of the clamping block 5 is fixed with an anti-skid pad 502, which is made of rubber material. The anti-skid pad 502 made of rubber material is fixed on the clamping surface of the clamping block 5. The rubber material has good elasticity and toughness, and can ensure the clamping accuracy when clamping the three-phase asynchronous motor, and buffer and protect the three-phase asynchronous motor.

[0027] A limiting rod 503 is fixed at one end of the clamp block 5, and the limiting rod 503 slides on the clamp plate 2. By fixing the limiting rod 503 at one end of the clamp block 5 and sliding it on the clamp plate 2, the movement of the clamp block 5 can be effectively limited, thereby increasing the stability of the device.

[0028] Combination Figure 2-Figure 4 One end of the bar 303 passes through the clamping plate 2, and the bar 303 is fixedly connected to the clamping plate 2 using a nut 304. The nut 304 is connected to the threaded head of one section of the bar 303 to connect the bar 303 and the clamping plate 2 together, so that the connection between the devices is stable and reliable, and the device can also be disassembled when maintenance is required.

[0029] A hydraulic rod 4 is fixed on the top of the workbench 1, and the hydraulic rod 4 is connected to the clamping plate 2 near the side of the driving assembly 3. The hydraulic rod 4 is fixed on the top of the workbench 1 and connected to one of the clamping plates 2 for driving, which can stably drive, is simple to operate and easy to control, and can well clamp the three-phase asynchronous motor, reducing manual operation.

[0030] A plurality of balls 201 are arranged at equal intervals at the bottom of the splint 2. The balls 201 roll in the ball grooves at the bottom of the splint 2, and the protruding parts thereof roll in the corresponding slide grooves 101 at the top of the workbench 1. The balls 201 are arranged at the bottom of the splint 2 to roll in the ball grooves, and the protruding parts thereof roll in the corresponding slide grooves 101 at the top of the workbench 1. The device can effectively reduce the friction between the components, thereby improving the smoothness and precision of the movement.

[0031] The gear 301 and the rack 302 are made of heat-treated cast iron. Cast iron is a cheap material. Although the strength, hardness and wear resistance of cast iron are relatively low, its performance is significantly improved after heat treatment by quenching and surface hardening. In the case of low-speed and low-load use in this case, the economy and durability of cast iron gear racks are well balanced.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
