Description

Technical Field

[0001] The present invention relates to the technical field of motor detection, and in particular to a permanent magnet motor detection device. Background Art

[0002] A permanent magnet motor is a motor that uses permanent magnets to generate a magnetic field. Its main components include a stator and a rotor. The stator is usually composed of windings, while the rotor is equipped with permanent magnets. The magnetic field of a permanent magnet motor is generated by permanent magnets. It does not need to generate a magnetic field through stator winding excitation like a traditional motor, which reduces the loss of excitation current, so its efficiency is relatively high. Under the same output power, permanent magnet motors consume less electrical energy, which can save users a lot of energy costs and have a good energy-saving effect. The permanent magnet motor detection device is a professional equipment or system combination used to measure, analyze and evaluate the various performance indicators, operating parameters and internal states of permanent magnet motors.

[0003] The existing patent (publication number: CN 117724019 A) discloses a motor permanent magnet detection device and detection method, including a conveying mechanism, a sorting mechanism and a detection mechanism, the sorting mechanism includes a hydraulic push rod, a lifting seat is installed on the hydraulic push rod, a rotating disk is rotatably installed on the lifting seat, and a limit groove for fixing the permanent magnet is provided on the rotating disk, and an electric push rod driving a clamping plate is installed on the inner walls of both sides of the limit groove, and the permanent magnet is fixed by two clamping plates, and the permanent magnet rotates with the rotating disk. The detection mechanism includes a mounting frame, and a motor-driven driving screw is installed on the mounting frame. The motor permanent magnet detection device and detection method are installed on the mounting frame. The driving screw drives the moving frame to move longitudinally by using the driving screw to adjust the position of the probe, and more point positions are taken, and the detection accuracy is higher. When the permanent magnet motor needs to be applied to practice, the key to the permanent magnet motor is the rotation size, such as the inner diameter of the stator and the outer diameter of the rotor. The accuracy of these dimensions is crucial to the size of the air gap inside the motor. When the permanent magnet motor drives the drive shaft to rotate, eccentric rotation of the drive shaft caused by incorrect dimensions will lead to unstable output and even failure of output rotation.

[0029] The detection mechanism 5 includes a detection barrel 51, which is fixedly connected to the surface of the workbench 2. A universal groove 52 is fixedly connected inside the detection barrel 51. A spring groove 53 is opened inside the universal groove 52. A rolling ball 54 is rotatably and slidably connected inside the spring groove 53. A universal ball 55 is rotatably connected inside the universal groove 52. A universal shaft 56 is fixedly connected to the surface of the universal ball 55. When the universal shaft 56 rotates inside the universal groove 52 through the universal ball 55, the rolling ball 54 will limit the universal ball 55, so that the universal shaft 56 remains in a horizontal state in the initial state.

[0030] The clamping mechanism 6 includes an annular slide groove 61, which is fixedly connected to the inside of the detection barrel 51. A telescopic spring 62 is arranged inside the universal shaft 56. The inside of the universal shaft 56 is slidably connected to a cross slider 63. A transverse groove 64 is provided on the surface of the cross slider 63. A sliding rod 65 is slidably connected to the inside of the annular slide groove 61. A slide groove 1 66 is provided on the surface of the sliding rod 65. A slide groove 1 67 is slidably connected to the inside of the slide groove 1 66.

The slide bar 610 is slidably connected inside the slide groove 68. The slide groove 68 pulls the end of the slide bar 67 to slide in the slide groove 66 opened in the slide bar 65 and approach the universal joint 56. At the same time, the front end of the slide bar 67 will slide forward on the side of the clamping rod 69, and at the same time, the clamping rod 69 will be squeezed to rotate toward the surface of the drive shaft 34 with the hinge point as the center of the circle, so as to clamp the drive shaft 34 and fix the horizontal position for easy detection.

[0031] The self-locking mechanism 7 includes a clamping rod 71, which is fixedly connected to the back of the cross slider 63. A fixing ring 72 is fixedly connected to the surface of the universal shaft 56. A push rod 73 is hinged on the side of the fixing ring 72. A card box 74 is fixedly connected to the side of one of the sliding rods 65. An inclined block 75 is slidably connected inside the card box 74. A protrusion 76 is fixedly connected to the side of the inclined block 75. A spring 77 is arranged inside the card box 74. The clamping mechanism 6 is provided with four groups in total, and only one group of sliding rods 65 is provided with the self-locking mechanism 7. There is only one clamping rod 71 on the back of the cross slider 63. When the protrusion 76 is squeezed, the inclined block 75 fixed on the side is driven to slide inside the card box 74. When the inclined plane block 75 slides, it will separate from the clamping rod 71. At this time, the cross slider 63 loses its restraint and is ejected by the elastic force of the telescopic spring 62. In this way, when the eccentricity of the drive shaft 34 is detected, the permanent magnet motor 33 will pop out immediately. This makes it easy for the staff to quickly discover and make adjustments in time, thereby improving the efficiency of detection. At the same time, when the cross slider 63 slides, the side clamping rod 71 will be driven to slide at the same time until the clamping rod 71 slides into the interior of the card box 74 and squeezes the inclined surface of the inclined plane block 75. When the clamping rod 71 slides over the inclined plane block 75, it will be stuck by the plane on the inclined plane block 75. In this way, the entire clamping mechanism 6 will be fixed to maintain stability before detection.

[0032] The use method and advantages of the present invention: When the permanent magnet motor detection device is used, the working process is as follows:

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , as shown;

[0034] When in use, first place the permanent magnet motor 33 on the surface of the slide plate 32, and then manually turn the handle 43. When the handle 43 is turned, it drives the rotating rod 42 to push the fixing rod 45 to rotate at the upper end of the rotating groove 44, and fix it with the permanent magnet motor 33. After the permanent magnet motor 33 is fixed, manually push the entire permanent magnet motor 33 to slide inside the limiting slide groove 31 through the slide plate 32. At the same time, when the permanent magnet motor 33 slides, it drives the drive shaft 34 to move until the drive shaft 34 moves to the inside of the universal shaft 56 and fits with the transverse groove 64 on the surface of the cross slide block 63.

[0035] At the same time, the driving shaft 34 will squeeze the cross slider 63. After being squeezed, the cross slider 63 will slide inward inside the universal shaft 56. When the cross slider 63 slides, it will drive the sliding rod 1 610 on the side to slide at the same time. When the sliding rod 1 610 slides, it will slide in the sliding groove 2 68 in the sliding rod 1 67. At the same time, the sliding groove 2 68 will pull the end of the sliding rod 1 67 to slide in the sliding groove 1 66 opened in the sliding rod 65 and approach the universal shaft 56. At the same time, the front end of the sliding rod 1 67 will move toward the side of the clamping rod 69. The cross slide 63 slides forward and squeezes the clamping rod 69 to rotate toward the surface of the drive shaft 34 with the hinge point as the center, clamps the drive shaft 34, and fixes the horizontal position for easy detection. At the same time, when the cross slide 63 slides, the side clamping rod 71 will slide at the same time until the clamping rod 71 slides into the interior of the card box 74 and squeezes the inclined surface of the inclined surface block 75. When the clamping rod 71 slides over the inclined surface block 75, it will be clamped by the plane on the inclined surface block 75. In this way, the entire clamping mechanism 6 will be fixed to maintain stability before detection.

[0036] After the preparation work is ready, the permanent magnet motor 33 is started, and the permanent magnet motor 33 drives the drive shaft 34 to rotate inside the universal shaft 56, and at the same time drives the cross slider 63 to rotate through the transverse groove 64, and the cross slider 63 drives the universal shaft 56 to rotate inside the universal groove 52, and at the same time drives the slide bar 67 to rotate through the clamping rod 69, and the slide bar 67 drives the slide bar 65 to rotate inside the annular slide groove 61. When the inner diameter of the stator and the outer diameter of the rotor cause the drive shaft 34 to rotate eccentrically, the drive shaft 34 will squeeze the universal shaft 56, and the universal shaft 56 will rotate. When the universal joint 56 is rotated, eccentricity will be generated, making its rotation diameter larger, at this time, the rotation diameter of the fixing ring 72 will be driven to increase, and when the fixing ring 72 is rotated, the push rod 73 hinged on the side will slide inside the card box 74 and squeeze the protrusion 76. When the protrusion 76 is squeezed, the inclined surface block 75 fixed on the side will slide inside the card box 74, and the inclined surface block 75 will separate from the card rod 71 when it slides, and the cross slide block 63 will lose its restraint at this time, and the cross slide block 63 will be ejected by the elastic force of the telescopic spring 62. At the same time, because the workbench 2 is in a slightly inclined state, it is convenient for the telescopic spring 62 to eject the cross slide block 63 and the permanent magnet motor 33, and the friction between the slide plate 32 and the limiting slide groove 31 is small, so it is easier to slide out. In this way, the permanent magnet motor 33 will pop out immediately when the eccentricity of the drive shaft 34 is detected, which makes it easy for the staff to quickly discover and make adjustments in time, thereby improving the efficiency of detection. At the same time, when the cross slide block 63 slides out, the cross slide block 63 slides inwardly inside the universal joint 56, and the cross slide block 6 When sliding, the sliding rod 1 610 on the side is driven to slide at the same time. When sliding, the sliding rod 1 610 will slide in the sliding groove 2 68 in the sliding rod 1 67, and at the same time, the sliding groove 2 68 will push the end of the sliding rod 1 67 to slide in the sliding groove 1 66 opened in the sliding rod 65 and slide outward. At the same time, the front end of the sliding rod 1 67 will slide forward on the side of the clamping rod 69, and at the same time, the clamping rod 69 will be squeezed to rotate toward the surface of the driving shaft 34 with the hinge point as the center of the circle, so as to open the clamping rod 69 and facilitate the ejection of the permanent magnet motor 33.

[0037] When the universal shaft 56 rotates inside the universal groove 52 through the universal ball 55, the rolling ball 54 will limit the universal ball 55 so that the universal shaft 56 remains horizontal in the initial state. At the same time, when the universal shaft 56 rotates eccentrically, the rolling ball 54 will be squeezed and squeezed into the inside of the spring groove 53.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Technical personnel in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention.
