Description

Technical Field

[0001] This utility model relates to the field of motor core processing technology, and in particular to a motor core flatness testing device. Background Technology

[0002] With increasing market demand for motors, the stator core is an important component that forms the magnetic flux circuit of the motor and fixes the stator coil. Since the stator core is made of silicon steel sheets, it has uneven end faces. Therefore, it is usually tested for flatness before leaving the factory.

[0003] Currently, most existing motor cores are measured using laser flatness measuring instruments. However, the surface of the motor core has multiple slots. Because of these slots, the laser flatness measuring instrument cannot accurately detect the flatness of the core, thus affecting the efficiency of motor core flatness detection. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing motor core flatness testing equipment, which is mostly used to measure the flatness of motor cores using laser flatness measuring instruments, cannot accurately detect the flatness of the core due to the presence of multiple grooves on the surface of the motor core, thus affecting the efficiency of motor core flatness testing. Therefore, this invention proposes a motor core flatness testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for testing the flatness of a motor core includes a worktable. Multiple mounting shafts are fixedly connected to the top of the worktable. A mounting plate is fixedly sleeved on the top of each mounting shaft. A servo cylinder is fixedly connected to the top of the mounting plate. A fixed plate is fixedly connected to the output end of the servo cylinder. The fixed plate is slidably sleeved with the mounting shafts. A motor is fixedly connected to one side of the fixed plate. A drive gear is keyed to the output end of the motor. A driven gear is rotatably connected to the bottom of the fixed plate, meshing with the drive gear. Multiple mounting posts are fixedly connected to the bottom of the driven gear. A mounting plate is fixedly connected to the bottom of the multiple mounting posts. A universal ball connector is rotatably connected to the bottom of the mounting plate. A detection pressure plate is engaged at the bottom end of the universal ball connector. A guide rail is fixedly connected to the bottom of the mounting plate. A laser flatness measuring instrument is slidably connected to the guide rail. A negative pressure seat is provided on the top of the worktable.

[0007] Furthermore, an adjustment knob is inserted into one side of the laser flatness measuring instrument.

[0008] Furthermore, multiple negative pressure pumps are fixedly connected to the bottom of the negative pressure seat, and the negative pressure pumps are connected to the negative pressure seat.

[0009] Furthermore, a cylinder is fixedly connected to the bottom of the workbench, and one end of the piston rod of the cylinder is fixedly connected to the bottom of the negative pressure seat.

[0010] Furthermore, a grating ruler is fixedly connected to the top of the workbench.

[0011] Furthermore, a mounting grating is fixedly connected to the top of the worktable.

[0012] Furthermore, a mounting bracket is fixedly connected to the top of the workbench, and a touch screen is provided on one side of the mounting bracket.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Driven by the motor and the meshing of the driving and driven gears, the mounting plate rotates, which in turn drives the laser flatness measuring instrument to rotate. The laser flatness measuring instrument then emits a laser beam onto the surface of the motor core, using the characteristics of reflected light to obtain flatness information, thereby detecting the flatness of the motor core and improving detection efficiency.

[0015] 2. Adjust the position of the laser flatness measuring instrument by moving it on the guide rail, and then tighten the adjustment knob to fix the laser flatness measuring instrument, so as to inspect motor cores of different specifications and improve the applicability of the testing equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A device for testing the flatness of a motor core includes a worktable 1. Multiple mounting shafts 2 are welded to the top of the worktable 1. A mounting plate 3 is fixedly sleeved at the top of each mounting shaft 2. A servo cylinder 4 is bolted to the top of the mounting plate 3. A fixing plate 5 is bolted to the output end of the servo cylinder 4. The fixing plate 5 is slidably sleeved with the mounting shafts 2. A motor 6 is bolted to one side of the fixing plate 5. A drive gear 7 is keyed to the output end of the motor 6. A driven gear 8 is rotatably connected to the bottom of the fixing plate 5, meshing with the drive gear 7. Multiple mounting posts 9 are welded to the bottom of the driven gear 8. A mounting plate 10 is welded to the bottom of the multiple mounting posts 9. A universal ball connector 11 is rotatably connected to the bottom of the mounting plate 10. A detection pressure plate 12 is snapped onto the bottom of the universal ball connector 11. Under the drive of the servo cylinder 4, the fixing plate 5 rotates, thereby causing the mounting plate 10 and the detection pressure plate 12 to move downwards, thus pressing the detection pressure plate 12 onto the motor core.

[0024] The bottom of the mounting plate 10 is fixed with a guide rail 13 by bolts. A laser flatness measuring instrument 14 is slidably connected to the guide rail 13. Driven by the motor 6, the drive gear 7 rotates. Under the action of the meshing of the drive gear 7 and the driven gear 8, the mounting plate 10 rotates, thereby driving the laser flatness measuring instrument 14 to rotate. The laser flatness measuring instrument 14 then emits a laser beam to the surface of the motor core. The flatness information is obtained by using the characteristics of reflected light, thereby detecting the flatness of the motor core. An adjustment knob 15 is inserted into one side of the laser flatness measuring instrument 14. Pulling the laser flatness measuring instrument 14 to move it on the guide rail 13 adjusts the position of the laser flatness measuring instrument 14. Tightening the adjustment knob 15 fixes the laser flatness measuring instrument 14 so as to detect motor cores of different specifications.

[0025] The top of the workbench 1 is equipped with a negative pressure seat 17. Multiple negative pressure pumps 16 are fixed to the bottom of the negative pressure seat 17 by bolts. The negative pressure pumps 16 are connected to the negative pressure seat 17. When the negative pressure pumps 16 and the negative pressure seat 17 work together, they generate negative pressure to fix the motor core on the negative pressure seat 17. The bottom of the workbench 1 is equipped with a cylinder 18 by bolts. One end of the piston rod of the cylinder 18 is fixedly connected to the bottom of the negative pressure seat 17. Driven by the cylinder 18, the negative pressure seat 17 and the motor core on it are lifted upward. The top of the workbench 1 is equipped with a grating ruler 19 by bolts to know the height of the motor core. The top of the workbench 1 is equipped with a mounting grating 20 by bolts. The top of the workbench 1 is equipped with a mounting bracket 21 by bolts. A touch screen 22 is provided on one side of the mounting bracket 21.

[0026] The working principle of this embodiment is as follows: In use, firstly, the motor core is placed on the negative pressure seat 17. Then, the negative pressure pump 16 is started. Under the cooperation of the negative pressure pump 16 and the negative pressure seat 17, a negative pressure is generated to fix the motor core on the negative pressure seat 17. Next, the cylinder 18 is started. Under the drive of the cylinder 18, the negative pressure seat 17 and the motor core on it are lifted upward. Then, the servo cylinder 4 is started. Under the drive of the servo cylinder 4, the fixing plate 5 rotates, thereby driving the mounting plate 10 and the detection pressure plate 12 to move downward, so that the detection pressure plate 12 presses on the motor core. Then, the motor 6 is started. Under the drive of the motor 6, the drive gear 7 rotates. Under the meshing action of the drive gear 7 and the driven gear 8, the mounting plate 10 rotates, thereby driving the laser flatness measuring instrument 14 to rotate. Then, the laser flatness measuring instrument 14 emits a laser beam to the surface of the motor core. The flatness information is obtained by using the characteristics of reflected light, thereby detecting the flatness of the motor core.
