Description

Technical Field

[0001] This utility model relates to the field of motor assembly technology, specifically to a motor assembly fixture. Background Technology

[0002] An electric motor assembly fixture is a tool or device used for installing and assembling electric motors. It typically consists of a fixture body, a support structure, and fixing devices. This fixture is designed to hold the various components of the motor in place, ensuring their correct position and orientation during assembly. The fixture usually has adjustable components to accommodate motors of different sizes and specifications. By using this assembly fixture, operators can assemble motors more easily and accurately, improving assembly efficiency and quality.

[0003] A search revealed that Chinese patent CN219504634U discloses a motor assembly fixture. This patent describes a method in which rotating a turntable drives a connecting shaft to rotate, which in turn drives a rotating shaft to rotate, which in turn drives a bevel gear set to rotate, which in turn drives a first threaded rod to rotate, which in turn drives a slider to move in the opposite direction, and the slider drives an arc plate to move, so that the magnetic tile fits into the motor housing. This facilitates the positioning of the magnetic tile and thus achieves the purpose of convenient assembly.

[0004] In this solution, the device achieves clamping and fixing by moving the arc plate in the opposite direction. However, the shape of the arc plate is fixed, while the curvature of the motor housing is different. Therefore, it is impossible to ensure that the arc plate and the motor housing fit together completely. As a result, wobbling and tilting will occur during assembly, which will greatly reduce the work efficiency. In order to solve this technical problem, this utility model proposes a motor assembly fixture. Summary of the Invention

[0014] (III) Beneficial Effects

[0015] This utility model provides a motor assembly fixture. It has the following advantages:

[0016] (1) By operating the throttle, the bidirectional threaded rod is driven to rotate in the fixed plate, thereby moving the connecting block at both ends, which in turn drives the clamping plate to clamp, ensuring that the motor housing remains stable during assembly. The movement of the connecting block and the clamping plate is limited by the positioning rod and the slide groove, ensuring that the movement direction and trajectory are consistent. The adjustment of the threaded column allows the anti-slip pad to adapt to the irregular shape of the motor housing, ensuring that the anti-slip pad is completely in contact with the surface of the housing, preventing slippage during assembly. The design of the buckle and the slot facilitates the replacement of the anti-slip pad, making maintenance more convenient. The overall structure makes the motor assembly process more efficient and precise, solving the problem of stable fixing and anti-slip of the housing during motor assembly, and improving work efficiency and assembly quality.

[0017] (2) By starting the cooling fan, the hot air on the surface of the motor is exhausted to reduce the motor temperature. The air outlet and exhaust outlet work together to exhaust the hot air from around the motor, maintain air circulation, and effectively improve the heat dissipation efficiency of the motor. The operation of these structures enables the motor to dissipate heat effectively during operation, avoid problems caused by overheating, and extend the service life of the motor.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] Example 1: A motor assembly fixture includes a base 1, a pair of fixing plates 2 fixedly connected to the bottom of the base 1, a bidirectional threaded rod 4 rotatably connected between the two fixing plates 2, a throttle 3 fixedly connected to one end of the bidirectional threaded rod 4, connecting blocks 5 threadedly connected to the outer walls of both ends of the bidirectional threaded rod 4, clamping plates 6 fixedly connected to the top of the two connecting blocks 5, connecting rods 7 fixedly connected to the bottom walls of both ends of the clamping plates 6, and a pair of positioning rods 8 fixedly connected between the two fixing plates 2, with the positioning rods 8 located on both sides of the bidirectional threaded rod 4. The connecting rods 7 are slidably connected to the outer walls of the positioning rods 8. A pair of second sliding grooves 10 are formed on the top of the base 1, with the connecting blocks 5 slidably connected within the second sliding grooves 10. Two pairs of first sliding grooves 9 are formed on the top of the base 1, with the first sliding grooves 9 located within the second sliding grooves. On both sides of the second 10, the connecting rod 7 is slidably connected in the first groove 9. The inside of both sides of the clamping plate 6 is threaded with threaded post 11. At the same time, the inside of both sides of the clamping plate 6 is provided with anti-slip soft pad 12, and the threaded post 11 on both sides is rotatably connected in the anti-slip soft pad 12. The top of both sides of the clamping plate 6 is provided with the second slot 18. At the same time, the top and bottom sides of the anti-slip soft pad 12 are provided with the first slot 14. The top of the connecting block 5 is fixedly connected with the second buckle 19, and the second buckle 19 is slidably connected in the first slot 14 below the anti-slip soft pad 12. At the same time, the outside of the clamping plate 6 is provided with the first buckle 13, and the first buckle 13 is U-shaped. The first buckle 13 is inserted into the first slot 14 and the second slot 18. The inner side of both sides of the clamping plate 6 is arc-shaped, and the anti-slip soft pad 12 is arc-shaped as a whole.

[0026] The motor housing 22 is placed between the two clamping plates 6. Then, the throttle 3 is rotated. Under the action of the throttle 3, the bidirectional threaded rod 4 begins to rotate within the fixed plate 2. The rotation of the threaded rod drives the connecting block 5 to move in a certain direction, and drives the clamping plate 6 on the connecting block to move outward, thus achieving a clamping effect. At the same time, as the clamping plate 6 moves, it is limited by the connecting rods 7 at the bottom on both sides to the positioning rod 8, ensuring that the movement direction is consistent. As the clamping plate 6 gradually approaches and presses against the motor housing 22, the anti-slip pad 12 comes into play to prevent the housing from sliding during assembly. Because the motor housing 22 has an irregular shape, the anti-slip pad 12 may not fit snugly on both sides. By rotating the threaded post 11 on the clamping plate 6, the threaded post causes the anti-slip pad 12 to bend inward on both sides and gradually come closer to the motor housing 22, achieving fine adjustment so that it completely covers the housing. The buckle 13 can be removed from the second slot 18 and the first slot 14 to replace the anti-slip pad 12. Through the cooperation of these steps, it is ensured that the base 1 does not wobble or tilt when fixed, thereby ensuring a more precise motor assembly process and improving work efficiency.

[0027] Example 2: The difference between this example and Example 1 is that a cooling fan 15 is fixedly connected inside the two side clamps 6, and several air outlets 16 are opened inside the clamps 6. An exhaust port 17 is opened inside the anti-slip soft pad 12, and the exhaust port 17 corresponds to the air outlet 16. An inner groove 20 is opened at each of the four corners of the base 1, and a bolt 21 is provided at each of the four corners of the base 1. The bolt 21 slides inside the bolt 21. A motor housing 22 is provided between the two side clamps 6.

[0028] The base 1 is installed on the equipment that needs to work by adjusting the bolts 21 to ensure a stable connection. When the motor is in use, the cooling fan 15 inside the clamp 6 is activated to cool the motor through the cooling fans 15 on both sides. At the same time, the air outlet 16 and the exhaust vent 17 work together to make the motor heat dissipation efficiency higher and extend the service life of the motor.

[0029] During operation, when the worker needs to assemble the motor, firstly, the base 1 is installed on the equipment to be worked on using adjusting bolts 21. Then, the motor housing 22 is placed between the two clamping plates 6. At this time, the throttle 3 is turned, which drives the bidirectional threaded rod 4 to rotate within the fixed plate 2. The rotation of the bidirectional threaded rod 4 drives the connecting blocks 5 at both ends to move in one direction, and drives the clamping plates 6 on the connecting blocks 5 to move in the opposite direction, thereby achieving the clamping function. At the same time, when the clamping plates 6 move, they are limited by the connecting rods 7 at the bottom on both sides to the positioning rods 8, thereby keeping the movement direction of the clamping plates 6 consistent. As the clamping plates 6 gradually approach and press against the motor housing 22, oil stains may appear due to motor assembly. At this time, the anti-slip pads 12 on the clamping plates 6 play an anti-slip role for the motor housing 22 during the assembly process. Since the motor housing 22 is irregularly shaped, the anti-slip pads 12 are designed to prevent slippage. If the two sides of pad 12 cannot get close enough, rotate the threaded post 11 on the clamping plate 6. Under the action of the threaded post 11, the two sides of the anti-slip pad 12 will bend inward and gradually get close to the outer wall of the motor housing 22, forming a wrapping state, thereby achieving a fine adjustment effect. At the same time, by removing the buckle 13 from the second slot 18 and the first slot 14, the anti-slip pad 12 can be replaced. Through their cooperation, the base 1 will not wobble or tilt when fixed, thus ensuring more precise assembly of the motor and greatly improving work efficiency. It can not only be assembled quickly, but also directly fix the motor for use. When the motor is in use, the cooling fan 15 inside the clamping plate 6 is turned on, and the cooling fans 15 on both sides are used to dissipate heat from the motor. At the same time, with the air outlet 16 and the exhaust vent 17, the motor's heat dissipation efficiency is higher, extending the motor's service life.
