Description

Technical Field

[0001] This utility model belongs to the field of motor manufacturing technology and relates to an adjustment and testing device used in motor manufacturing. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. After the motor is manufactured, it undergoes a no-load dynamic balance test. This test helps to determine whether the mass distribution of the equipment is uniform and whether the rotating shaft of the equipment is consistent with its geometric axis.

[0003] The existing technology has the following technical problems: Current motor no-load dynamic balancing tests use a dynamic balancing tester, but this test cannot directly show the deviation diameter of the output shaft when there is imbalance. Operating a dynamic balancing machine requires a certain level of professional knowledge and experience; for beginners, mastering the various parameters and operating skills may require a lengthy learning and training process. Different models of dynamic balancing machines also differ in their operating methods, increasing the complexity of operation and the professional requirements for users. Therefore, we have made improvements and proposed an adjustment and testing device for motor production. Utility Model Content

[0004] The technical problem this invention aims to solve is that while a dynamic balancing tester can be used to perform no-load dynamic balancing tests on motors, this method cannot directly demonstrate the deviation diameter of the output shaft when there is an imbalance. Furthermore, operating a dynamic balancing machine requires a certain level of professional knowledge and experience; for beginners, mastering the various parameters and operating techniques may require a lengthy learning and training process. Different models of dynamic balancing machines also differ in their operating methods, increasing the complexity of operation and the professional requirements for users.

[0005] The adjustment and testing device for motor production described in this utility model includes a fixed base and a motor body. The fixed base has four symmetrical sliding grooves, and the same fixing component is installed in each of the four sliding grooves. The motor body is mounted on the fixed base through the fixing component. A testing component is installed on the fixed base, and the fixing component is used in conjunction with the testing component.

[0006] The detection assembly includes a mounting frame on which six first screws are connected in a ring-shaped thread. A mounting box is installed at one end of each first screw. A sliding sleeve is installed on the outside of the mounting box. A return spring is installed inside the sliding sleeve. A lifting rod is installed at the bottom of the return spring. An arc-shaped block is installed at the bottom of the lifting rod. The six arc-shaped blocks are connected in a ring on the output shaft of the motor body. A sliding groove is formed on the sliding sleeve. A first rack is installed on one side of the top of the lifting rod. The first rack is located at the sliding groove of the sliding sleeve.

[0007] A worm gear is rotatably connected inside the mounting box. A first gear is installed at one end of the worm gear that passes through the mounting box. The first gear meshes with a first rack. A worm wheel is meshed with one side of the worm gear, and a drive screw is installed on the worm wheel.

[0008] The two ends of the drive screw are rotatably connected to the inner wall of the same mounting box, and a drive lifting frame is threadedly connected to the drive screw. The top of the drive lifting frame is slidably connected to the top of the mounting box.

[0009] The fixing assembly includes two sliding rods that are slidably connected in two sliding grooves. Two clamping rods are installed on the sliding rods, and anti-slip pads are installed on the clamping rods. The four clamping rods are clamped on the outside of the motor body.

[0010] The sliding rod is threaded with a fixing screw, and the two fixing screws are threaded with the same fixing plate. The fixing plate has a placement groove, and the bottom of the motor body is placed in the placement groove on the fixing plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: through the linkage of components such as the arc block, lifting rod, return spring, first rack, worm, worm wheel and drive lifting frame, when the motor output shaft deviates, it can be directly observed through the action of the drive lifting frame, which allows non-professionals to quickly determine whether there is a problem with the motor output shaft.

[0012] Compared to traditional dynamic balancing testers, this testing component requires no complex setup or parameter adjustments. Simply fix the motor to the base, align the output shaft with the arc-shaped block, and then start the motor. This makes the operation simpler and faster. Due to the intuitiveness and ease of operation of this testing component, it reduces the professional knowledge and experience required of users. Even beginners can master its use in a short time without the need for lengthy learning and training. Attached Figure Description

[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] Example 1

[0026] like Figures 1-6 As shown, the adjustment and testing device for motor production includes a fixed base 1 and a motor body 9. The fixed base 1 has four symmetrically arranged sliding grooves 2, each containing the same fixing component. The motor body 9 is mounted on the fixed base 1 via the fixing component. A testing component is mounted on the fixed base 1, and the fixing component works in conjunction with the testing component. This device has a certain degree of versatility; by using the fixing component in conjunction with the drive component, it can be applied to different types of motors. Only slight adjustments are needed based on the motor's size and the position of the output shaft to meet testing requirements. Traditional dynamic balancing tests may require multiple adjustments and tests to obtain accurate results, while this testing component can quickly reflect the offset of the motor's output shaft, thereby improving testing efficiency.

[0027] The testing assembly includes a mounting bracket 10, on which six first screws 12 are connected in a ring-shaped thread. By rotating the first screws 12, the distance between the first screws 12 and the connected mounting box and its arc-shaped block 22 and the motor output shaft is adjusted, thus enabling testing of motors with different output shafts. A mounting box 13 is mounted at one end of each first screw 12. A sliding sleeve rod 14 is mounted on the outside of the mounting box 13. A return spring 23 is installed inside the sliding sleeve rod 14. A lifting rod 15 is mounted at the bottom of the return spring 23. An arc-shaped block 22 is mounted at the bottom of the lifting rod 15. The six arc-shaped blocks 22 are ring-shaped and overlap the output shaft of the motor body 9. A sliding sleeve 14 has a groove 11. A first rack 16 is installed on one side of the top of the lifting rod 15. The first rack 16 is located at the groove 11 of the sliding sleeve. A worm 18 is rotatably connected inside the mounting box 13. A first gear 17 is installed at one end of the worm 18 that passes through the mounting box 13. The first gear 17 and the first rack 16 are meshed with each other. A worm wheel 19 is meshed with one side of the worm 18. A drive screw 20 is installed on the worm wheel 19. The two ends of the drive screw 20 are rotatably connected to the inner wall of the same mounting box 13. A drive lifting frame 21 is threadedly connected to the drive screw 20. The top of the drive lifting frame 21 is slidably connected to the top of the mounting box.

[0028] During operation, the motor body 9 is fixed to the fixed base 1 by the fixing assembly, so that the output shaft of the motor body 9 overlaps with the arc-shaped block 22 on the detection assembly. Then, the motor body 9 is started, and the motor body 9 drives the output shaft to rotate. When the output shaft rotates, its center of mass is separated from the center of rotation. At this time, the output shaft on the motor body 9 rotates and shifts, thus pressing the arc-shaped block 22 that overlaps with it. The arc-shaped block 22 drives the lifting rod 15 to move upward, thus pressing the return spring 23. At the same time, the lifting rod 15 moves and drives the first rack 16 to slide in the slide groove 11, so that the first rack 16 drives the first gear 17 that meshes with it to rotate. The rotation of the first gear 17 drives the worm 18 to rotate on the mounting box 13. The worm 18 drives the worm wheel 19, which is meshed with it, to rotate. This causes the worm wheel 19 to drive the first screw 12, which is connected to it, to rotate. The first screw 12 drives the drive lifting frame 21, which is threaded to it, to slide on the top of the mounting box 13, causing the drive lifting frame 21 to push out of the mounting box 13. When the motor body 9 stops rotating, its output shaft no longer presses the arc block 22, causing the return spring 23 on the lifting rod 15 to drive the lifting rod 15 to slide on the sliding sleeve. This, in turn, drives the drive lifting frame 21 of the mounting box 13 to reset through the first rack 16, so that it can be used again.

[0029] Through the linkage of components such as the arc block 22, lifting rod 15, return spring 23, first rack 16, worm 18, worm wheel 19 and drive lifting frame 21, when the motor output shaft deviates, it can be directly observed through the action of the drive lifting frame 21. This allows non-professionals to quickly determine whether there is a problem with the motor output shaft.

[0030] Example 2

[0031] like Figure 1 and Figure 6 As shown, the fixing assembly includes two sliding rods 3, which are slidably connected in two sliding grooves 2. The design of the sliding rods 3 and sliding grooves 2 allows the clamping rods 4 to be adjusted according to the size and shape of the motor body 9. This means that the fixing assembly can be used for motors of different sizes and models, improving its versatility and flexibility. Two clamping rods 4 are installed on the sliding rods 3, and anti-slip pads 6 are installed on the clamping rods 4. The use of anti-slip pads 6 not only increases the clamping force, but also reduces the wear or scratches on the surface of the motor body 9 by the clamping rods 4, thereby protecting the integrity of the motor body 9. The four clamping rods 4 are clamped on the outside of the motor body 9. The sliding rods 3 are threadedly connected to the fixing screws 5, and the two fixing screws 5 are threadedly connected to the same fixing plate 7. The fixing plate 7 has a placement groove 8, and the bottom of the motor body 9 is placed in the placement groove 8 on the fixing plate 7.

[0032] In use, the motor body 9 is placed in the placement slot 8 on the fixing plate 7, and then the fixing screw 5 is rotated. The fixing screw 5 drives the sliding rod 3 to slide in the sliding groove 2. The sliding rod 3 drives the two clamping rods 4 to move to both sides of the motor body 9, thereby clamping the motor body 9. With the four clamping rods 4 clamping the outside of the motor body 9 and supplemented by anti-slip pads 6, it can be ensured that the motor body 9 will not shake or move during the test. This stability is crucial for obtaining accurate test results because it reduces the influence of external factors, such as vibration or displacement, on the test results.

[0033] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
