Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor stator grinding technology, specifically a motor stator grinding device. Background Technology
[0002] The motor stator is an important component of the motor, and its machining accuracy directly affects the motor's performance, efficiency, and service life. This places higher demands on the machining accuracy and surface quality of the motor stator, thus requiring a motor stator grinding device.
[0003] A Chinese patent with authorization announcement number CN220128394U discloses a grinding device for motor stator cores, belonging to the field of grinding technology. It includes a base, an auxiliary plate slidably connected to the base, and auxiliary components provided on the base. In this application, the clamping component can clamp the motor stator core, and the auxiliary component can control the movement of the motor stator core, which facilitates the grinding of the motor stator core, reduces the possibility of injury to the operator, and improves the grinding accuracy of the motor stator core.
[0004] However, the above solution still has some problems. The device cannot fix stators of different sizes, which means that the same device cannot fix stators of multiple specifications, thus reducing the versatility of the device. Therefore, a motor stator grinding device is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a motor stator grinding device.
[0006] The technical solution adopted by this utility model to solve its technical problem is a motor stator grinding device, including: a processing table, a first support frame fixedly connected to the inner wall of the processing table, a first drive motor installed at the bottom of the first support frame, a base plate fixedly connected to the output end of the first drive motor, a limit groove formed on the upper surface of the base plate, a connecting shaft fixedly connected to the central shaft of the upper surface of the base plate, a rotating plate installed at one end of the connecting shaft, a first bolt threadedly connected to the internal threads of the rotating plate and the connecting shaft, a sliding groove formed on the rotating plate, a threaded hole formed on the rotating plate, sliding rods slidably connected inside the threaded hole and the limit groove, a positioning plate fixedly connected to one end of one set of sliding rods, an adjusting plate fixedly connected between two sets of sliding rods, an anti-slip pad fixedly connected to one side of the adjusting plate, a second bolt threadedly connected to the internal threads of the positioning plate and the threaded hole, the two sets of sliding rods being located in the limit groove and the sliding groove respectively, and the positioning plate being fixed by the first bolt. The three components cooperate to fix the position of the adjusting plate, so that multiple sets of anti-slip pads can be completely attached to the inner wall of the motor stator, thereby fixing the motor stator.
[0007] Preferably, a second support frame is fixedly connected to the upper surface of the processing table, and an electric telescopic rod is installed on one side of the second support frame. By activating the electric telescopic rod and adjusting the position of the grinding disc, the grinding depth of the motor stator can be adjusted.
[0008] Preferably, a second drive motor is installed at the telescopic end of the electric telescopic rod, and a grinding disc is fixedly connected to the output end of the second drive motor. The grinding disc is opposite to the connecting shaft. When the second drive motor is started, the grinding disc is driven to rotate, thereby cooperating with the electric telescopic rod to grind the motor stator.
[0009] Preferably, a water tank is fixedly connected to the bottom of the processing table, a drain pipe is installed on one side of the water tank, and a transmission pipe is installed on the water tank. One end of the transmission pipe extends into the interior of the water tank. After the device is used, the control valve in the drain pipe is opened to discharge the water in the water tank, which facilitates the replacement of the water in the water tank.
[0010] Preferably, the other end of the transmission pipe is mounted on the second support frame, and a water pump is installed on the transmission pipe. The water pump is fixed to the back of the second support frame, thereby connecting the transmission pipe to the second connecting frame and improving the stability of the device operation.
[0011] Preferably, the water pump is installed on one side of the second support frame, the water tank is equipped with a filter plate, and a cleaning port is opened on one side of the water tank. The debris generated during the grinding of the motor stator falls onto the filter plate through the spray water. The debris on the filter plate can be cleaned through the cleaning port to avoid clogging of the filter plate and thus avoid affecting the secondary use of water resources, thereby avoiding affecting the cooling treatment of the motor stator during grinding.
[0012] The advantages of this invention are as follows: When the rotating plate rotates clockwise, multiple sets of sliding grooves drive the sliding rod to move outward, which in turn drives multiple sets of adjusting plates and anti-slip pads to spread outward, thereby expanding the ring size of the fixing component. When the rotating plate rotates counterclockwise, the ring size of the fixing component shrinks, and at the same time, the anti-slip pads adhere to the inner wall of the motor stator, increasing the friction between the two. This allows the stator to be fixed in position without external force, thus enabling the fixing of motor stators of different sizes and improving the versatility of the grinding device.
[0013] This utility model starts a water pump, which draws water from the tank through a transmission pipe, spraying water onto the grinding area of the motor stator to cool the grinding area. This quickly removes heat, preventing the stator material from annealing, deforming, or developing thermal stress due to overheating. At the same time, it washes the grinding debris off the filter plate, keeping the working area clean and reducing the health hazards of dust to operators. It not only protects the workpiece and tools but also improves processing quality and efficiency, thereby improving the overall effect of the grinding process. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0022] Please see Figure 1-5As shown, a motor stator grinding device includes: a processing table 1, a first support frame 2 fixedly connected to the inner wall of the processing table 1, a first drive motor 3 installed at the bottom of the first support frame 2, a base plate 4 fixedly connected to the output end of the first drive motor 3, a limit groove 5 opened on the upper surface of the base plate 4, a connecting shaft 6 fixedly connected to the central shaft of the upper surface of the base plate 4, a rotating plate 7 installed at one end of the connecting shaft 6, a first bolt 8 threadedly connected to the internal threads of the rotating plate 7 and the connecting shaft 6, a sliding groove 9 opened on the rotating plate 7, a threaded hole 10 opened on the rotating plate 7, a sliding rod 11 slidably connected inside the threaded hole 10 and the limit groove 5, a positioning plate 12 fixedly connected to one end of a set of sliding rods 11, an adjusting plate 13 fixedly connected between the two sets of sliding rods 11, an anti-slip pad 14 fixedly connected to one side of the adjusting plate 13, and a second bolt 15 threadedly connected to the internal threads of the positioning plate 12 and the threaded hole 10.
[0023] The motor stator is a crucial component of a motor, and its machining accuracy directly affects the motor's performance, efficiency, and lifespan. Therefore, the stator's circumference needs to be ground during production. However, existing devices cannot secure stators of different sizes, preventing the same equipment from handling stators of multiple specifications. This leads to the proposal of a motor stator grinding device. In practical use, the motor stator to be ground is placed on the outside of multiple sets of adjusting plates 13. Rotating the rotating plate 7 clockwise moves the sliding rod 11 outwards via multiple sets of sliding grooves 9, which in turn causes the multiple sets of adjusting plates 13 and anti-slip pads 14 to expand outwards, thereby enlarging the circumference of the fixing components. Finally, the second bolt 15 is screwed into the positioning plate 12 and the screw... Within the perforated hole 10, in conjunction with the limiting groove 5, the position of the adjusting plate 13 can be fixed, allowing the anti-slip pad 14 to adhere to the inner wall of the electronic stator. Subsequently, the first bolt 8 is screwed into the rotating plate 7 and the connecting shaft 6 to fix the rotating plate 7, thereby enabling the fixing of larger-sized motor stators. Rotating the rotating plate 7 counterclockwise causes the adjusting plate 13 to adhere to the connecting shaft 6, reducing the size of the fixing assembly. This, in conjunction with the second bolt 15 and the first bolt 8, allows the position of the adjusting plate 13 and the rotating plate 7 to be fixed, enabling the fixing of smaller-sized motor stators. This allows the device to fix motor stators of different sizes, thereby improving the versatility of the grinding device.
[0024] Please see Figure 1-5As shown, a second support frame 16 is fixedly connected to the upper surface of the processing table 1. An electric telescopic rod 17 is installed on one side of the second support frame 16. A second drive motor 18 is installed at the telescopic end of the electric telescopic rod 17. A grinding disc 19 is fixedly connected to the output end of the second drive motor 18. The grinding disc 19 is opposite to the connecting shaft 6. A water tank 20 is fixedly connected to the bottom of the processing table 1. A drain pipe 21 is installed on one side of the water tank 20. A transmission pipe 22 is installed on the water tank 20. One end of the transmission pipe 22 extends into the interior of the water tank 20. The other end of the transmission pipe 22 is installed on the second support frame 16. A water pump 23 is installed on the transmission pipe 22. The water pump 23 is installed on one side of the second support frame 16. A filter plate 24 is installed inside the water tank 20. A cleaning port is opened on one side of the water tank 20.
[0025] After the motor stator is fixed, the second drive motor 18 is started to rotate the grinding disc 19. Then, the electric telescopic rod 17 is started to adjust the position of the grinding disc 19. At the same time, the first drive motor 3 is started to rotate the motor stator. The two work together to adjust the grinding depth of the motor stator. While grinding, the water pump 23 is started to draw water from the water tank 20 through the transmission pipe 22, so that water is sprayed onto the grinding area of the motor stator to cool the grinding area. This can quickly remove heat and prevent the stator material from annealing, deforming or generating thermal stress due to overheating. At the same time, the grinding debris is washed off onto the filter plate 24 to keep the working area clean and reduce the health hazards of dust to the operators. This not only protects the workpiece and tools, but also improves the processing quality and efficiency, thereby improving the overall effect of the grinding process.
[0026] The working principle is as follows: The motor stator to be ground is placed on the outside of multiple sets of adjusting plates 13. Rotating the rotating plate 7 clockwise moves the sliding rod 11 outward through multiple sets of sliding grooves 9, which in turn causes the multiple sets of adjusting plates 13 and anti-slip pads 14 to expand outward, thus enlarging the ring of the fixing assembly. Rotating the rotating plate 7 counterclockwise shrinks the ring of the fixing assembly. The second bolt 15 is screwed into the positioning plate 12 and the threaded hole 10, engaging with the limiting groove 5, thus fixing the position of the adjusting plate 13 and ensuring the anti-slip pad 14 is in contact with the inner wall of the electronic stator. Then, the first bolt 8 is screwed into the rotating plate 7 and the connecting shaft 6 to fix the rotating plate 7, thereby enabling the grinding of the motor stator. A motor stator of the same size is fixed. The first drive motor 3 is started to rotate the motor stator. At the same time, the second drive motor 18 is started to rotate the grinding disc 19. Then, the electric telescopic rod 17 is started to adjust the position of the grinding disc 19. The two work together to adjust the grinding depth of the motor stator. The water pump 23 is started to draw water from the water tank 20 through the transmission pipe 22, so that water is sprayed onto the grinding area of the motor stator to cool the grinding area. At the same time, the grinding debris is washed off onto the filter plate 24, which can keep the working area clean and improve the processing quality and efficiency, thereby improving the overall effect of the grinding process.
