Description

Technical Field

[0001] This application relates to the field of testing tools, and in particular to a simple testing tool for the dimensions of motor laminations. Background Technology

[0002] Motor lamination refers to the process of stacking a series of thin iron sheets (also called laminations) together to form the stator or rotor core of a motor. These laminations are usually made of electrical steel (silicon steel), which has good magnetic permeability and electrical resistance.

[0003] Thickness errors in laminated laminations can lead to variations in eddy current losses. In motor design, a varnish coating is used in the laminated core to form an insulator to protect the laminations, preventing eddy currents from flowing across the cross-section and thus reducing eddy currents. Uneven lamination thickness can increase eddy current losses and affect motor efficiency. Therefore, the thickness of the laminates is crucial. While workers typically use calipers to measure thickness, this process involves numerous considerations and requires readings for each lamination individually. This not only makes the inspection process cumbersome and time-consuming, but manual readings are also prone to errors. Utility Model Content

[0004] To reduce the difficulty of testing and increase the testing speed, this application provides a simple testing tool for the dimensions of motor laminations.

[0005] The simple tool for detecting the dimensions of motor laminations provided in this application adopts the following technical solution:

[0006] Preferably, a simple tool for detecting the size of motor laminations includes a mounting plate, with detection plates mounted on both ends of the mounting plate. The distance between the two detection plates is fixed, and the lamination to be detected just extends into the gap between the two detection plates.

[0007] By adopting the above technical solution, when the staff checks the thickness of the stacked sheets, they insert the stacked sheets between two testing plates. If they can be inserted exactly, it means that the size is qualified. If they cannot be inserted or there is a gap, it means that the size is unqualified. This reduces the difficulty of testing and increases the testing speed.

[0008] Preferably, a contact sensor is fixedly connected to the side wall of the detection plate, and a display screen for displaying the data of the contact sensor is mounted on the mounting plate.

[0009] By adopting the above technical solution, when the stacked piece is inserted between two detection plates, if the stacked piece is slightly smaller, it is not easy for the staff to observe the gap. At this time, the staff can observe the data detected by the contact sensor on the display screen, thereby reducing the possibility of staff observation errors.

[0010] Preferably, both ends of the mounting plate are provided with sliding grooves, and sliders slide in the sliding grooves. The two detection plates are respectively fixedly connected to the two sliders, and a fixing component for fixing the detection plates is provided in the sliding groove.

[0011] By adopting the above technical solution, the staff can adjust the distance between the two detection plates by using a slider. Then, the slider is fixed by a fixing component to fix the distance between the two detection plates and make it the standard size of the stack to be tested, so that stacks of various sizes can be tested.

[0012] Preferably, each of the sliding grooves has a limiting groove, and each of the opposite sidewalls of the sliders is fixedly connected to a limiting block, with the two limiting blocks slidably connected within the two limiting grooves respectively.

[0013] By adopting the above technical solution, when the slider moves, the limiting block can limit the range of slider movement, thereby preventing the slider from sliding out of the groove. At the same time, the side wall of the limiting block abuts against the inner wall of the limiting groove, and the end of the slider that slides out of the groove is suspended in the air. Under its own weight and the weight of the detection plate, it tends to tilt downward. The limiting block abuts against the limiting groove, which can compensate for the end of the slider that slides out.

[0014] Preferably, the fixing component includes an abutment block and a bolt. The abutment block slides within the sliding groove and abuts against the side wall of the slider. The bolt passes through and is threadedly connected to the side wall of the mounting plate, and is fixedly connected to the abutment block.

[0015] By adopting the above technical solution, after the operator drives the slider to slide to the appropriate position, the operator can push the abutment block closer to the slider and press it against the side wall of the slider by tightening the bolt, thereby limiting the movement of the slider and fixing the distance between the two detection plates.

[0016] Preferably, a rubber pad is fixedly connected to the abutment block, and the rubber pad abuts against the side wall of the slider.

[0017] By adopting the above technical solution, the rubber pad can increase the friction between the abutment block and the slider, thereby improving the fixing effect.

[0018] Preferably, the sliding groove is provided with a driving assembly for driving the two sliders to move simultaneously. The driving assembly includes a lead screw, a first bevel gear, a second bevel gear, and a motor. The two ends of the lead screw are respectively rotatably connected to the opposite inner walls of the limiting groove. The limiting block is threadedly connected to the lead screw. The first bevel gear is fixedly sleeved on the lead screw. The motor is fixedly installed on the outer wall of the mounting plate. The second bevel gear is fixedly connected to the rotating shaft of the motor. The second bevel gear meshes with the first bevel gear.

[0019] By adopting the above technical solution, when the operator needs to adjust the position of the slider to adjust the distance between the two detection plates, the operator starts the motor. The motor rotates and drives the second bevel gear to rotate. The rotation of the second bevel gear drives the first bevel gear to rotate. The rotation of the first bevel gear drives the lead screw to rotate. The rotation of the lead screw drives the limit block to move, thereby driving the slider to move.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. When staff are checking the thickness of the stacked sheets, they insert the stacked sheets between two testing plates. If the sheets can be inserted precisely, the dimensions are considered acceptable. If the sheets cannot be inserted or there is a gap, the dimensions are considered unacceptable. This reduces the difficulty of the test and increases the speed of the test.

[0022] 2. When the stacked piece is inserted between two detection plates, if the stacked piece is slightly smaller, it is not easy for the staff to observe the gap. At this time, the staff can observe the data detected by the contact sensor on the display screen, which can reduce the possibility of staff observation errors.

[0023] 3. The staff adjusts the distance between the two detection plates by using a slider. Then, the slider is fixed by a fixing component to fix the distance between the two detection plates and make it the standard size of the stack to be tested, so that stacks of various sizes can be tested.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] Example 1

[0032] This application discloses a simple tool for detecting the dimensions of 15 laminations in a motor, such as... Figure 1 As shown, the device includes a mounting plate 1, which is rectangular in shape. Detection plates 2 are mounted at both ends of the mounting plate 1, with a fixed distance between them. The stacked piece to be tested fits precisely into the gap between the two detection plates 2. Contact sensors 3 are fixedly connected to the opposite sidewalls of the two detection plates 2. A display screen 4 for displaying pressure sensor data is mounted on the mounting plate 1.

[0033] The implementation principle of Embodiment 1 of this application is as follows: When the operator is inspecting the thickness of the stacked sheet, the operator inserts the stacked sheet between two inspection plates 2. If it can be inserted precisely, it indicates that the size is qualified; if it cannot be inserted or there is a gap, it indicates that the size is unqualified. This reduces the difficulty of inspection and thus increases the inspection speed. After the operator inserts the stacked sheet to be tested between the two inspection plates 2, the operator can observe the data of the contact sensor 3 on the display screen 4 to determine whether there is a gap between the workpiece to be tested and the inspection plate 2, thereby reducing the possibility of operator observation errors.

[0034] Example 2

[0035] like Figure 2 As shown, the difference between Embodiment 2 and Embodiment 1 is that: Sliding grooves 5 are provided at both ends of the mounting plate 1 along the horizontal direction. A slider 6, rectangular in shape, slides within the sliding grooves 5. Two detection plates 2 are respectively fixedly welded to the ends of the two sliders 6. A fixing assembly 7 for fixing the detection plates 2 is provided within the sliding grooves 5. Scale lines 19 are provided on the top surfaces of the two sliders 6. Operators can read the distance between the two detection rods according to the corresponding scale lines 19 on the sliders 6, thereby detecting the stacked pieces of the corresponding size. Limiting grooves 8 are provided on the inner walls of the sliding grooves 5 along their own extension direction. Limiting blocks 9, rectangular in shape, are fixedly welded to the opposite sidewalls of the sliders 6. The two limiting blocks 9 are slidably connected to the inner walls of the two limiting grooves 8. The fixing component 7 includes an abutment block 10 and a bolt 11. The abutment block 10 slides in the sliding groove 5 in a direction perpendicular to the sliding groove 5. A rubber pad 12 is fixedly adhered to the abutment block 10. The rubber pad 12 abuts against the side wall of the slider 6. The bolt 11 passes through and is threadedly connected to the side wall of the mounting plate 1. One end of the bolt 11 is fixedly welded to the side of the abutment block 10 away from the rubber pad 12.

[0036] The implementation principle of Embodiment 2 of this application is as follows: the operator can adjust the distance between the two detection plates 2 by adjusting one side slider 6 or both sides slider 6, thus making it suitable for the detection of stacked plates of various sizes. When it is necessary to adjust the distance between the two detection plates 2, the operator first tightens the bolt 11 to drive the abutment block 10 away from the side wall of the slider 6, thereby releasing the position limitation of the slider 6. Then, the operator drives the slider 6 to slide in the sliding groove 5 to a suitable position. The operator then tightens the bolt 11 to push the abutment block 10 closer to the slider 6 and presses it against the side wall of the slider 6. The rubber pad 12 can increase the friction between the abutment block 10 and the slider 6, improve the fixing effect, thereby limiting the movement of the slider 6 and fixing the distance between the two detection plates 2. When the slider 6 moves, the limiting block 9 can limit the range of movement of the slider 6, thereby preventing the slider 6 from sliding out of the groove. At the same time, the side wall of the limiting block 9 abuts against the inner wall of the limiting groove 8. The end of the slider 6 that slides out of the groove is suspended in the air and tends to tilt downward under its own weight and the weight of the detection plate 2. The limiting block 9 abuts against the limiting groove 8, which can compensate for the end of the slider 6 that slides out.

[0037] Example 3

[0038] like Figure 4 As shown, the difference between this embodiment 3 and embodiment 2 is that: a driving assembly 13 for driving two sliders 6 to move simultaneously is provided in the sliding groove 5. The driving assembly 13 includes a lead screw 14, a first bevel gear 17, a second bevel gear 16, and a motor 15. The motor 15 is fixedly installed on the outer wall of the mounting plate 1. The lead screw 14 rotates horizontally in the limiting groove 8. The threads on both sides of the lead screw 14 are arranged oppositely. The two ends of the lead screw 14 are respectively rotatably connected to the opposite inner walls of the limiting groove 8. A guide rod 18 is horizontally provided in another limiting groove 8. The two ends of the guide rod 18 are welded to the opposite inner walls of the limiting groove 8. Limiting blocks 9 are located on opposite sides. One limiting block 9 slides on the guide rod 18, and the other limiting block 9 is threadedly connected to the lead screw 14. The first bevel gear 17 is fixedly sleeved on the middle position of the lead screw 14. The second bevel gear 16 is fixedly welded to the rotating shaft of the motor 15. The second bevel gear 16 meshes with the first bevel gear 17.

[0039] The implementation principle of Embodiment 3 of this application is as follows: When the operator needs to adjust the position of the slider 6 to adjust the distance between the two detection plates 2, the operator starts the motor 15. The rotation of the motor 15 drives the second bevel gear 16 to rotate, the rotation of the second bevel gear 16 drives the first bevel gear 17 to rotate, the rotation of the first bevel gear 17 drives the lead screw 14 to rotate, and the rotation of the lead screw 14 drives the limit block 9 to move, thereby driving the slider 6 to move. The cooperation of the lead screw 14 and the motor 15 can simultaneously and synchronously drive the two sliders 6. The distance the slider 6 moves can be set by the program to increase the accuracy of the distance between the two detection plates.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
