[0002] In the field of motor manufacturing, static electricity has always been a key factor affecting product quality and production safety. When the motor shaft is being manufactured and polished, it is necessary to use a fixture to fix the motor, which will come into contact with the motor. Before the motor is clamped, due to friction, induction and other factors, the motor components are very prone to accumulating static electricity. This static electricity may not only cause the breakdown and damage of electronic components, greatly reducing the product qualification rate, but may also generate sparks during the discharge process, leading to safety accidents in flammable and explosive environments, seriously threatening the safety of production operations.
[0003] Traditional static eliminators typically eliminate static electricity in motors by using static eliminators to remove static electricity inside the motor. However, most existing static eliminators are not easily adjustable, meaning they only support motors of specific sizes. This makes them unsuitable for eliminating static electricity in motors of different sizes, resulting in limited applicability of traditional static eliminators. Utility Model Content

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0024] Please see Figure 1-4This utility model provides a technical solution: a static electricity elimination device for motor production process, including a processing table 1. An electric telescopic rod 4 is fixedly installed on one side of the processing table 1. An installation plate 2 is fixedly connected to the output end of the electric telescopic rod 4. A first motor 3 is fixedly connected to one side of the installation plate 2. A grinding disc 5 is fixedly installed at the output end of the first motor 3. A first sliding groove 6 and a second sliding groove 10 are opened at the top of the processing table 1. A bidirectional threaded rod 7 is rotatably connected inside the first sliding groove 6. A slider 8 is threadedly sleeved at the opposite threads of the bidirectional threaded rod 7. A fixing clamp 9 is fixedly connected to the top of each slider 8. A groove 17 is opened inside each of the two fixing clamps 9. A static electricity elimination component is set inside each of the two grooves 17. The static electricity elimination component includes two static electricity guide rods 14. A pressure spring 20 is fixedly installed at the opposite ends of the two static electricity guide rods 14. The opposite ends of the two pressure springs 20 are respectively fixedly connected to the inner wall of the corresponding groove 17.
[0025] Furthermore, each of the two fixed clamping blocks 9 has a circular groove 13 at its opposite end. The interior of the two circular grooves 13 is connected to the interior of the corresponding groove 17. The opposite ends of the two electrostatic conductors 14 slide through the interior of the corresponding circular grooves 13.
[0026] Furthermore, a limiting groove 18 is provided on one side of the inner wall of each of the two grooves 17, and a limiting block 19 is slidably connected to the inner wall of each of the two limiting grooves 18. One end of each limiting block 19 is fixedly connected to the outer surface of the corresponding electrostatic conductor 14.
[0027] Furthermore, the bottom surface of the inner wall of each of the two grooves 17 is provided with a through groove 21, and the inner wall of each of the two through grooves 21 is slidably connected with a movable conductive plate 11. The outer surface of each of the two movable conductive plates 11 is slidably connected with the inner wall of the second sliding groove 10. The bottom end of each of the two movable conductive plates 11 is rotatably mounted with a conductive wheel 12, and the outer surface of each of the two conductive wheels 12 is in contact with the ground.
[0028] Furthermore, a connecting plate 15 is fixedly connected to one side of each of the two movable conductive plates 11, and one end of each connecting plate 15 is fixedly connected to the outer surface of the corresponding electrostatic conductive rod 14.
[0029] Furthermore, a second motor 16 is fixedly installed on one side of the processing table 1. The output end of the second motor 16 rotates through the interior of the first slide groove 6 and is fixedly connected to one end of the bidirectional threaded rod 7.
[0030] Furthermore, the second motor 16 is started, and its output end drives the bidirectional threaded rod 7 to rotate in the first slide groove 6. Because the bidirectional threaded rod 7 has opposite threads, the two sliders 8 that are threadedly connected to it will move relative to or away from each other along the threaded rod, thereby driving the fixed clamping block 9 to move synchronously. The motor is placed between the two fixed clamping blocks 9, so that its rotating shaft faces the grinding disc 5. The movement of the sliders 8 achieves precise positioning and firm clamping of the parts, ensuring stability during the grinding process of the rotating shaft.
[0031] Furthermore, when the two fixed clamping blocks 9 move relative to each other, the two movable conductive plates 11 will also move along with the fixed clamping blocks 9, and at the same time the two conductive wheels 12 will roll on the ground to keep in constant contact with the ground.
[0032] Furthermore, during the clamping process, the two sides of the motor will squeeze the electrostatic guide rod 14. After being subjected to force, the electrostatic guide rod 14 overcomes the elastic force of the pressure spring 20 and moves into the groove 17. The pressure spring 20 stores elastic potential energy. Then, the limiting block 19 slides in the limiting groove 18, thereby preventing the electrostatic guide rod 14 from deviating or rotating during the movement, thus ensuring that the electrostatic guide rod 14 stably contacts the part to be processed. At the same time, the movement of the electrostatic guide rod 14 drives the connecting plate 15 to move. The connecting plate 15 then pushes the moving conductive plate 11 to slide in the second slide groove 10. The moving conductive plate 11 drives the conductive wheel 12 to keep in contact with the ground, providing a path for electrostatic conduction.
[0033] Furthermore, the static electricity generated during the motor's production process is collected by the static electricity conductor 14, which is in contact with the part to be processed. The static electricity travels along the static electricity conductor 14, through the connecting plate 15, to the movable conductive plate 11, and then is released to the ground through the conductive wheel 12, effectively eliminating static electricity during the motor's production process. After processing is completed and the clamping of the motor part to be processed is released, the pressure spring 20 releases its elastic potential energy, pushing the static electricity conductor 14 to reset, so that static electricity can be eliminated for the next new part to be processed. At the same time, the movable conductive plate 11 is reset under the action of the pressure spring 20, ensuring that the device is ready to be put into new static electricity elimination work at any time.
[0034] Furthermore, through the design of this electrostatic component, the two electrostatic guide rods 14 will first contact the motor to be clamped, so that the motor can easily release static electricity to the ground through the electrostatic guide rods 14, connecting plate 15, moving conductive plate 11 and conductive wheel 12 during the clamping process, thereby facilitating the elimination of static electricity on the motor. At the same time, through the design of the moving conductive plate 11, the electrostatic component can be moved, and together with the fixed clamping block 9, it can clamp motors of different sizes, thereby eliminating static electricity on motors of different sizes, which can improve the applicability of the electrostatic elimination device.
