Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of motor testing devices, and in particular to a motor clamping device for drag testing. Background Technology
[0002] The motor-to-motor test is an experimental method used to measure motor performance. It typically involves two motors: the motor under test (DUT) and the driving motor. The driving motor acts as the power source, driving the DUT, which in turn generates electricity. This method simulates the load conditions of the DUT under actual operation, allowing for the measurement of its performance parameters under different loads.
[0003] In the prior art, such as the patent with publication number CN216486134U, a motor motion control platform is disclosed. By rotating the rotating handle, the screw can be driven to rotate, thereby driving the slide plate to move towards the boss. This causes the second motor mounted on the top of the slide plate to move to the coupling, and the output shaft of the second motor is fixedly connected to the coupling. The coupling enables the first motor and the second motor to be coaxially connected, which facilitates the installation and disengagement of the second motor for working purposes, making it convenient and quick.
[0004] For example, patent CN218524837U discloses a motor-to-motor type test device that uses an electric chuck to connect or disconnect the test motor from the torque and speed sensor.
[0005] However, in the aforementioned prior art, both the tested motor and the drive motor are mounted on the platform's support frame. Since the support frame does not have a lifting function, the height of the installed motor cannot be adjusted when testing motors and drive motors of different diameters to ensure that the tested motor and drive motor are aligned.

[0032] Combination Figure 1 and Figure 2 As shown, a handle 9 is installed on the handwheel 8, and the handle 9 is inserted into the front side of the handwheel 8 near the edge. Further, a plurality of pin holes 8a are evenly distributed in a ring on the handwheel 8, and an anti-rotation pin 10 is inserted into one of the pin holes 8a, the rear end of the anti-rotation pin 10 being inserted into the base 1.
[0033] Combination Figure 3 , Figure 5 and Figure 6 As shown, the width of the horizontal plate 7a is smaller than the width of the vertical plate 7b, such that the front and rear sides of the vertical plate 7b protrude from the horizontal plate 7a respectively; two pairs of vertical grooves 1b are respectively provided on the front and rear walls of the inner cavity of the base 1; the vertical plate 7b of one of the transmission components 7 slides in cooperation with one pair of grooves 1b; the vertical plate 7b of the other transmission component 7 slides in cooperation with the other pair of grooves 1b.
[0034] Combination Figure 1 and Figure 2 As shown, mounting blocks 1c are integrally formed on the lower part of the front and rear sides of the base 1; bolts are provided on the mounting blocks 1c.
[0035] Combination Figure 1 and Figure 4 As shown, the groove 1a is a semi-circular groove, and the V-shaped pad 2 is provided with a semi-cylindrical surface; the semi-cylindrical surface of the V-shaped pad 2 cooperates with the groove 1a.
[0036] Combination Figure 1 As shown, the pressure plate 3 includes a main body 3a and ear plates 3b integrally formed at both ends of the main body 3a; the screw 4 passes through the ear plates 3b and is connected to the base 1; the V-shape of the pressure plate 3 is formed on the main body 3a.
[0037] Combination Figure 7 As shown, the operating principle of the above-mentioned motor clamping device is as follows:
[0038] In use, the two motor clamping devices are installed opposite each other inside the temperature chamber and fixed to the bottom wall of the temperature chamber by bolts using the mounting block 1c on the base 1. One motor clamping device is used to clamp the motor under test, and the other motor clamping device is used to clamp the drive motor. The specific steps include:
[0039] Step S1: Place the motor under test or the driving motor: First, place the motor under test or the driving motor on the V-groove of the V-shaped pad 2, then fasten the pressure plate 3 on the motor under test or the driving motor, and then pass the screw 4 through the ear plate 3b of the pressure plate 3 and connect it to the base 1. Do not tighten the screw 4 at this time.
[0040] Step S2: Adjust the height of the motor under test or the motor being driven: The operator holds the handle 9 and turns the handwheel 8, which drives the drive gear 5 to rotate. Since the drive gear 5 and the driven gear 6 mesh with each other, the driven gear 6 can be driven to rotate, which in turn drives the corresponding transmission component 7 to move up and down. Since the horizontal plate 7a of the transmission component 7 abuts against the V-shaped pad 2, the V-shaped pad 2 can be driven to move up and down.
[0041] Combination Figure 1 As shown, specifically, when it is necessary to drive the V-shaped pad 2 to move upward, turn the handwheel 8 clockwise. At this time, the driving gear 5 rotates clockwise, while the driven gear 6 rotates counterclockwise. The driving gear 5 can drive the left transmission component 7 to move upward, and the driven gear 6 can drive the right transmission component 7 to move upward. The horizontal plates 7a of the two transmission components 7 together push the V-shaped pad 2 upward. Conversely, turn the handwheel 8 counterclockwise. At this time, the driving gear 5 rotates counterclockwise, while the driven gear 6 rotates clockwise. The driving gear 5 can drive the left transmission component 7 to move downward, and the driven gear 6 can drive the right transmission component 7 to move downward. The V-shaped pad 2 and the motor it is clamped with descend by their own weight. When the semi-cylindrical surface of the V-shaped pad 2 is in contact with the semi-circular groove 1a of the base 1, the V-shaped pad 2 descends to its lowest point.
[0042] Step S3: By adjusting the height of the V-shaped pads 2 on the two motor clamping devices, when the central axes of the tested motor and the driving motor are aligned and centered, insert the anti-rotation pin 10 through the pin hole 8a of the handwheel 8 and onto the base 1 to prevent the handwheel 8 from rotating on its own. At this point, the driving gear 5 and the driven gear 6 can be locked. Then tighten the screw 4. The clamping of the tested motor and the driving motor is now complete. Finally, connect the tested motor and the driving motor using a coupling to perform the drag test.
[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
