Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0049] refer to Figures 1 to 8 ,like Figure 1 As shown, this embodiment provides a roller shutter door motor testing device, including: a test box 1, a load testing component 3, a support mechanism 6, and a mounting component. The test box 1 is mounted on a frame 2, and the load testing component 3 is mounted inside the test box 1. The front of the test box 1 has an openable door 11 to facilitate the insertion and removal of the motor 4 to be tested. The support mechanism 6 is slidably mounted inside the test box 1. By moving the support mechanism 6 relative to the load testing component 3, the motor 4 can be easily connected to the load testing component 3. The mounting component for mounting the motor 4 to be tested is mounted on the support mechanism 6. The support mechanism includes a fixing component, a lifting component, and an operating component. The fixing component is slidably mounted inside the test box 1. The lifting component is threadedly connected to the operating component. The mounting component is fixed on the lifting component. By rotating the operating component, the lifting component can be raised and lowered along the fixing component, thereby adjusting the height of the mounting component. By adjusting the height of the motor 4, it can be ensured that motor shafts of different specifications can be accurately connected to the load testing component 3.

[0050] like Figure 8 As shown, the fixing components include: a base 61, a cover plate 62, and a slider 68. The cover plate 62 is installed on the bottom of the base 61 by screws; the slider 68 is connected to the bottom of the cover plate 62 and slides in cooperation with the slide rail 5 inside the test chamber 1.

[0051] Preferably, the base 61 has a first movable groove 611, a second movable groove 612 and a pair of limiting holes 613. The second movable groove 612 is connected to the bottom of the first movable groove 611, and the pair of limiting holes 613 are arranged opposite to each other on both sides of the first movable groove 611.

[0052] In this embodiment, the operating components include: a finger rod 66, a turntable 67, and a threaded rod portion 65. The finger rod 66 is rotatably disposed in the first movable groove 611, and an end plate 661 is vertically connected to the bottom of the finger rod 66. The end plate 661 is accommodated in the second movable groove 612. The turntable 67 is sleeved on the finger rod 66 and is located between the base 61 and the support seat 63. The threaded rod portion 65 is integrally connected to the upper end of the finger rod 66 and is threadedly connected to the lifting assembly.

[0053] In this embodiment, the lifting assembly includes a support base 63, two limiting plates 64, and a limiting block 641. The support base 63 is threadedly connected to the threaded rod portion 65. The two limiting plates 64 are installed opposite each other on both sides of the support base 63, and the limiting plates 64 are slidably engaged with the corresponding limiting holes 613 so that the support base 63 can be raised and lowered smoothly. One of the limiting plates 64 is provided with a scale line, and a limiting block 641 is provided at its lower end. The limiting block 641 is used to position the zero point of the support base 63 so that different motors 4 can move upward from the zero point. This makes the positioning of the output shaft of the motor 4 more accurate when connected to the load testing assembly 3, thereby making the test results of the load testing assembly 3 more accurate.

[0054] Preferably, the support base 63 has a threaded hole 631 that is threaded to engage with the threaded rod portion 65.

[0055] like Figure 7 As shown, the slide rail 5 has several slots 51. Knurled screws 53 and sliders 68 are threaded together. The knurled screws 53 can pass through the sliders 68 and hold them in the slots 51, thus locking the sliders 68 and the slide rail 5. When the support mechanism 6 is moved, the knurled screws 53 are loosened, and the sliders 68 can move along the slide rail 5. When the motor 4 is connected to the load test assembly 3, the knurled screws 53 are tightened. The head of the knurled screws 53 has a protrusion, which holds in the slots 51, thereby locking the position of the sliders 68 on the slide rail 5.

[0056] The slide rail 5 is also equipped with a limiting baffle 52 that can limit the slider 68. When the slider 68 abuts against the limiting baffle 52, the support mechanism 6 reaches the extreme position on the left end, at which point the motor shaft can be installed in conjunction with the coupling 33. Therefore, by setting the limiting baffle 52, the installation position of the motor 4 and the coupling 33 can be made more accurate.

[0057] In this embodiment, by rotating the turntable 67, the threaded rod 65 and the finger rod 66 can rotate as a whole. With the cooperation of the limiting plate 64 and the limiting hole 613, the support seat 63 can move up and down on the base 61. When the support seat 63 moves down to the limit block 641 abutting against the upper end face of the base 61, the support seat 63 is at the zero point position. Therefore, this application can adaptively adjust the height of the motor 4 according to the different diameters of the output shaft of the motor 4, so that the motor 4 can be accurately connected with the coupling 33. This allows the load testing assembly 3 to test motors 4 of different specifications, thus making it more applicable.

[0058] like Figure 3 and Figure 4 As shown, the mounting components include: mounting plate 7, several bolts 8, several washers 10, and several wing nuts 9. Mounting plate 7 is fixedly mounted on top of support base 63; several bolts 8 can position and mount motor 4 on mounting plate 7; washers 10 are fitted onto corresponding bolts 8; wing nuts 9 can be threaded onto corresponding bolts 8.

[0059] Preferably, the mounting plate 7 has a first through hole 71 and several second through holes 72. The first through hole 71 is used to accommodate the output shaft, and the second through holes 72 are used for the bolts 8 to pass through.

[0060] Preferably, the pad 10 has a third through hole 101, which is connected to the second through hole 72.

[0061] When installing motor 4, make sure the flange of motor 4 is close to the right side of mounting plate 7, the output shaft passes through the first through hole 71, and then the bolt 8 passes through the flange, the second through hole 72 and the third through hole 101 in sequence. Finally, tighten the wing nut 9 onto the bolt 8.

[0062] like Figure 2 As shown, the load test assembly 3 includes: a bracket 31, a motor dynamometer 32, and a coupling 33. The bracket 31 is set inside the test box 1; the motor dynamometer 32 is mounted on the bracket 31; the coupling 33 is mounted on the motor dynamometer 32, and the output shaft of the motor 4 can be connected to the coupling 33.

[0063] Preferably, the test chamber 1 is also equipped with a decibel detector 12 and an infrared thermometer 13. When the motor dynamometer 32 is started to perform a load test on the motor 4, the decibel detector 12 can detect the noise of the motor 4 when it is working, and the infrared thermometer 13 can test the condition of the motor 4 during its operation. Therefore, this application can simultaneously realize load testing, noise testing and heat generation testing, thereby making the testing efficiency higher.

[0064] Working principle: Operate turntable 67 to lower base 61 to the zero position. Then, install the motor 4 to be tested on mounting plate 7. Adjust the height of motor 4 by rotating turntable 67 to ensure precise connection between the output shaft of motor 4 and coupling 33. Loosen knurled screw 53 and move slider 68 to bring motor 4 closer to coupling 33. Stop when slider 68 hits limit baffle 52 and tighten knurled screw 53. At this point, the output shaft corresponds to coupling 33. Finally, fix the output shaft to coupling 33. After preparation, start motor dynamometer 32, decibel meter 12 and infrared thermometer 13. Motor dynamometer 32 applies load to motor 4 to test the load condition of motor 4. During the load operation of motor 4, decibel meter 12 and infrared thermometer 13 perform noise test and heat test respectively.

[0065] In summary, this application not only enables multiple tests to be performed simultaneously, but also allows for testing of different motors 4 (with different output shaft diameters), and features convenient use, precise installation, and high work efficiency.

[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
