[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] Please refer to Figure 1 An embodiment of the present utility model provides a portable motor testing device, including components such as a base plate 1, a motor tester 2 and a three-dimensional adjustment mechanism 3. The following describes the various components of this embodiment in detail with reference to the accompanying drawings.

[0023] like Figure 1 As shown, the motor tester 2 can be fixedly set on the base plate 1, and the three-dimensional adjustment mechanism 3 can be movably set forward and backward in front of the output part of the motor tester 2 and is located on the base plate 1. The three-dimensional adjustment mechanism 3 can clamp the motor under test and adjust its position so that the output shaft of the motor under test is connected to the connecting shaft 21 of the motor tester 2.

[0024] like Figure 2 and Figure 3 As shown, the three-dimensional adjustment mechanism 3 may include a movable plate 31, a support plate 32, a clamping assembly 33, an X-axis displacement platform 34 and a Z-axis lifting platform 35. The Z-axis lifting platform 35 is movably set on the top of the movable plate 31 through the X-axis displacement platform 34, the support plate 32 is fixedly set on the top surface of the Z-axis lifting platform 35, and the clamping assembly 33 is installed on the top of the support plate 32.

[0025] Specifically, the clamping assembly 33 may include a top plate 331, a clamping strip 332, an adjusting guide post 333, a clamp pad 334, a V-shaped clamp block 335 and a pad 336. The V-shaped clamp block 335 is mounted on the support plate 32 through the clamp pad 334 and can move left and right relative to the clamp pad 334. The clamp pad 334 is detachably arranged between the support plate 32 and the V-shaped clamp block 335 and can move left and right relative to the support plate 32. Four adjusting guide posts 333 are provided and are fixed at the four corners of the support plate 32 respectively. The top plate 331 is detachably mounted on the four adjusting guide posts 333 through locking pieces and is located above the V-shaped clamp block 335. The clamping strip 332 is fixedly arranged on the bottom surface of the top plate 331 and corresponds to the V-shaped clamp block 335. The pad 336 is detachably arranged on both inner sides of the top surface of the V-shaped clamp block 335.

[0026] Among them, the clamping assembly 33 is used to clamp the motor under test to ensure that it does not move during the test process, can clamp stably, and prevent test errors caused by misoperation or motor sliding. The V-shaped structure of the V-shaped clamp block 335 is designed to match the overall structure of the motor under test, providing better clamping effect and stability. By adjusting the X-axis displacement platform 34 and the Z-axis lifting platform 35, the motor under test can be accurately adjusted in the horizontal and height directions. It can adapt to motors under test with different axis heights, and facilitate precise position adjustment according to the sizes of different motors under test, thereby improving the compatibility of the test and having strong versatility.

[0027] Preferably, the pad strip 336 can be made of nylon, PP or PE.

[0028] The pads 336 in this embodiment are preferably made of nylon. Nylon has high wear resistance and can withstand certain pressures and repeated friction during the clamping process without breaking, thus maintaining a long service life. It can also absorb impact forces to a certain extent, protecting the motor under test from damage during adjustment or testing. Furthermore, nylon is easy to form and process, and its shape and size can be customized according to specific needs to meet the clamping requirements of different motors under test.

[0029] In this embodiment, the X-axis displacement platform 34 can be configured as an X-axis manual fine-tuning translation slide, and the Z-axis lifting platform 35 can be configured as a Z-axis manual fine-tuning lifting slide.

[0030] Among them, the X-axis manual fine-tuning translation slide and the Z-axis manual fine-tuning lifting slide both use the common screw-thread manual fine-tuning slides on the market, and manual fine-tuning allows operators to easily make quick and precise adjustments without the need for complex electric drive and control systems.

[0031] Preferably, the adjustment guide column 333 can be set as a threaded rod, and the locking piece includes four Y-shaped nuts 41 and four locking nuts 42. Each locking nut 42 is threadedly connected to the adjustment guide column 333 and abuts against the bottom surface of the top plate 331. Each Y-shaped nut 41 is threadedly connected to the adjustment guide column 333 and is located on the top surface of the top plate 331. The Y-shaped nut 41 can be conveniently tightened by the operator directly by hand, which is convenient for quickly clamping the motor under test and improving installation efficiency.

[0032] like Figure 4 As shown, in order to further provide a flexible adjustment mechanism, the top surface of the support plate 32 can be recessed with a first X-axis adjustment groove 321 along the X-axis direction, the bottom of the clamp pad 334 is fixedly connected to a second slide bar 3341 that is slidably connected to the first X-axis adjustment groove 321, the top surface of the clamp pad 334 is recessed with a second X-axis adjustment groove 3342 along the X-axis direction, and the bottom of the V-shaped clamp block 335 is fixedly connected to a third slide bar 3351 that is slidably connected to the second X-axis adjustment groove 3342.

[0033] like Figure 5 As shown, a Y-axis adjustment groove 11 can be recessed along the Y-axis direction on the top surface of the base plate 1 below the three-dimensional adjustment mechanism 3, and a first slide bar 311 is fixedly connected to the bottom of the movable plate 31 with a sliding connection to the Y-axis adjustment groove 11. Adjustment holes 312 are respectively provided on the two side edges of the movable plate 31, and a number of threaded holes 12 corresponding to the bottom of the adjustment holes 312 are provided on the base plate 1.

[0034] In specific implementation, when the overall position of the three-dimensional adjustment mechanism 3 needs to be adjusted, the movable plate 31 can move back and forth and pass through the adjustment hole 312 in sequence at an appropriate position through the fixing screws and then be threadedly connected to the threaded hole 12, thereby fixing the entire three-dimensional adjustment mechanism 3 on the base plate 1.

[0035] Preferably, supporting feet 13 may be spaced apart on both sides of the bottom of the base plate 1 .

[0036] like Figure 6 As shown, the motor tester 2 may include components such as a controller 22 and a test host 23, which are used to provide stable power output during testing, ensure the accuracy and reliability of the test process, and simulate the actual working environment to provide accurate test data. According to actual needs, the motor tester can also adopt various common motor testers currently on the market, and this embodiment does not impose any restrictions.

[0037] It should be noted here that the motor tester 2 of this embodiment can be connected to common control devices currently on the market, such as computers, control panels, and control cabinets, through the wires in the junction box 4. The control device has the functions of measuring, reading and recording the corresponding motor performance parameters, but this embodiment does not involve improvements in this aspect, so it will not be repeated here.

[0038] The working principle of this embodiment is as follows:

[0039] like Figure 7 As shown, first, the motor under test 101 is placed in the V-shaped clamping block 335 of the clamping assembly 33, and then the position of the clamping strip 332 above it is adjusted and locked. The three-dimensional adjustment mechanism 3 can accurately adjust the position of the motor under test 101 so that its output shaft is connected to the connecting shaft 21 of the motor tester 2. Since the sizes of different motors under test 101 are different and the adjustment range of the Z-axis lifting platform 35 is limited, the clamp pad 334 can be used as an auxiliary for installation or removal as needed. If the motor under test 101 and the motor tester 2 cannot be aligned with each other with or without the clamp pad 334, the height of the motor under test 101 can be adjusted by installing or removing the pad 336 so that the output shaft of the motor under test 101 is connected to the connecting shaft 21 of the motor tester 2, and the installation of the motor under test 101 is completed.

[0040] In summary, the utility model has high integration and is easy to operate. The motor under test and the motor tester can be precisely adjusted through the three-dimensional adjustment mechanism, thereby effectively reducing the test error. It has a compact structure and occupies little space, and can be easily placed in various workplaces and desktops.

[0041] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
