Example 1
[0022] Please see Figures 1-5 This utility model discloses a multi-functional adaptable precision dynamometer, including a workbench 1 and a control console 2 located on one side of the workbench 1, as well as a drag testing component 3, an auxiliary testing component 4, a height adjustment component 5, and a motor fixing component 6, wherein:
[0023] A protective cover 11 is fixed to the workbench 1 by screws, and the control console 2 is equipped with a control panel 21 and an industrial computer 22.
[0024] Please refer to the appendix. Figure 3 The test assembly 3 includes a load motor 31, one end of which is connected to a coupling 32. A reflector 33 is fixed to one side of the coupling 32 by screws. A speed sensor 34 is symmetrically arranged on the opposite side of the reflector 33. A torque sensor 35 is connected to one end of the coupling 32. Specifically, when the reflector 33 on the coupling 32 rotates, it works with the speed sensor 34 to measure the rotational speed of the test motor 7.
[0025] Please refer to the appendix. Figure 4 The auxiliary test component 4 includes a thermocouple sensor 41 and an acceleration sensor 42. The height adjustment component 5 includes a base 51. Several hydraulic cylinders 52 are connected to the bottom of the base 51. The base 51 is fitted with symmetrically arranged V-shaped clamps 61 and slides together. A test motor 7 is provided between the V-shaped clamps 61.
[0026] The test motor 7 is mounted on the base 51. One end of the test motor 7 is fixed to one end of the coupling 32, and the other end of the coupling 32 is fixedly connected to the test shaft 351 of the torque sensor 35.
[0027] In this embodiment, the hydraulic pump drives the oil cylinder 52 to rise and fall, thereby making the connecting shaft of the test motor 7 on the base 51 the same height as the test shaft 351. The test shaft 351 and the test motor 7 are fixedly connected by the coupling 32. The torque sensor 35, speed sensor 34, thermocouple sensor 41, and acceleration sensor 42 monitor the torque, speed, temperature and vibration data of the motor in real time. It can not only measure basic performance parameters, but also provide early warning of potential equipment failures. Example 2
[0028] Based on the above embodiment 1, please refer to the appendix. Figure 2 as well as Figure 5 The worktable 1 includes an upper plate 12 and a base plate 13. The base 51 passes through the upper plate 12 and slides in fit. The speed sensor 34 and the torque sensor 35 are electrically connected to the control console 2.
[0029] The top surface of the base 51 is symmetrically welded with a fixing spiral post 62, which passes through the crossbeam 63. A fixing knob 64 is provided above the crossbeam 63, and a fixing nut 65 is provided below it. The fixing spiral post 62 is screwed together with the fixing knob 64 and the fixing nut 65.
[0030] A limiting cylinder 66 is welded to one side of the crossbeam 63. The limiting cylinder 66 is fitted with a bidirectional spiral shaft 67 and rotates within it. Both ends of the bidirectional spiral shaft 67 are fitted with V-shaped clamps 61 and rotate within them. Specifically, the bidirectional spiral shaft 67 is limited by the limiting cylinder 66 and rotates within it.
[0031] The V-shaped clamp 61 fits into one side of the crossbeam 63 and slides in fit. A turntable 68 is welded to one end of the bidirectional spiral shaft 67. Thermocouple sensor 41 is fixed to the base plate 13 by screws. Thermocouple sensor 41 is electrically connected to thermal patch 43. Specifically, the V-shaped structure of the V-shaped clamp 61 can adapt to and clamp power equipment of various sizes.
[0032] The thermal patch 43 is attached to the top surface of the upper platform 12. The acceleration sensor 42 is installed on the top of the upper platform 12. The acceleration sensor 42 and the thermocouple sensor 41 are electrically connected to the control console 2. Specifically, the thermal patch 43 collects the thermal signal of the power equipment and transmits it to the thermocouple sensor 41 to convert it into an electrical signal.
[0033] In this embodiment, rotating the fixing knob 64 in conjunction with the fixing nut 65 adjusts the height of the crossbeam 63 so that the bottom of the crossbeam 63 abuts against the test motor 7 and fixes it in the vertical direction. Then, rotating the turntable 68 drives the bidirectional spiral shaft 67 to rotate in the limiting cylinder 66. The bidirectional spiral shaft 67 drives the V-shaped clamps 61 at both ends to move towards the center through the spiral force, thereby clamping the test motor 7. This can quickly and conveniently fix power equipment of different models and sizes.
[0034] The working principle and usage process of this utility model are as follows: When in use, firstly, according to the size and shape of the power equipment to be tested, the test motor 7 is placed on the base 51, so that the bottom of the test motor 7 is attached to the thermal pad 43, and its connecting shaft is aligned with the test shaft 351 of the torque sensor 35 in the horizontal direction. Then, the hydraulic pump is started to drive the oil cylinder 52 to lift and lower, thereby driving the connecting shaft of the test motor 7 on the base 51 to be at the same height as the test shaft 351. Then, the test shaft 351 and the test motor 7 are fixedly connected using the coupling 32.
[0035] After the test motor 7 is placed stably, rotate the fixing knob 64 and the fixing nut 65 to raise and lower the fixing screw column 62, thereby adjusting the height of the crossbeam 63 so that the bottom of the crossbeam 63 abuts against the test motor 7 and fixes it in the vertical direction. Then rotate the turntable 68 to drive the bidirectional screw shaft 67 to rotate in the limiting cylinder 66. The bidirectional screw shaft 67 drives the V-shaped clamps 61 at both ends to move towards the center through the screw force, thereby clamping the test motor 7.
[0036] Connect the test motor 7 to the power supply and start the device via the control console 2. The motor starts working. The test motor 7 drives the test shaft 351 to rotate via the coupling 32. The torque sensor 35 measures the output torque of the test motor 7 in real time. The connecting shaft at the other end of the torque sensor 35 drives the coupling 32 to rotate synchronously. The reflector 33 on the coupling 32 works with the speed sensor 34 to measure the rotational speed of the test motor 7 when it rotates. Thermocouple sensor 41 monitors the temperature of the motor in real time through the thermal patch 43 attached to the motor. Accelerometer 42 monitors the vibration of the motor in real time.
[0037] The data collected by each sensor is transmitted to the control console 2. The measurement and analysis software on the control screen 21 processes the data in real time, calculates parameters such as function and efficiency based on torque and speed, and displays these parameters, along with temperature and vibration data, on the control screen 21 in real time.
