Description

Technical Field

[0001] This utility model relates to the field of conductive slip ring testing, and in particular to a signal testing instrument for different rotational speeds. Background Technology

[0002] In aerospace, new energy power generation, industrial automation, medical devices and other fields, conductive slip rings are the core components for transmitting signals and electrical energy between rotating and stationary parts. Their operational stability directly determines the reliability of the entire equipment. During operation, the shaft of the conductive slip ring needs to rotate synchronously with the rotating parts of the equipment, and the rotor is linked with the shaft to achieve current conduction.

[0003] Existing conductive slip ring testing typically involves first measuring the shaft speed using a tachometer, then detecting the vibration frequency using an external data acquisition device connected to a vibration sensor, and finally manually measuring the rotor temperature using an infrared thermometer. However, this process requires using multiple devices with different functions, which is cumbersome, time-consuming, and makes it difficult to achieve simultaneous acquisition of multiple parameters, severely impacting the efficiency and reliability of the testing.

[0004] Therefore, it is necessary to design a signal testing instrument that can detect the rotational speed and vibration frequency of the conductive slip ring shaft while simultaneously detecting the rotor temperature, so as to facilitate comprehensive detection and evaluation of the operating status and improve the reliability and efficiency of detection at different rotational speeds. Utility Model Content

[0005] To overcome the shortcomings of current testing methods that require the use of multiple devices with different functions, which are cumbersome, time-consuming, and difficult to achieve simultaneous acquisition of multiple parameters, thus seriously affecting the efficiency and reliability of testing, this utility model provides a signal testing instrument at different speeds that can detect the rotational speed and vibration frequency of the conductive slip ring shaft while simultaneously detecting the rotor temperature. This facilitates comprehensive testing and evaluation of the operating status and improves the reliability and efficiency of testing.

[0006] The technical solution of this utility model is as follows: a signal testing instrument at different rotation speeds, including a base, suction cups, air pumps, a handle, buttons, an adjustment component, and a detection component. The base has two suction cups connected to the left and right sides, and two air pumps connected to the left and right sides. A handle is connected to the upper side of the base, and a button is slidably connected to the front side of the middle part of the handle. The upper part of the handle is provided with an adjustment component for adjusting the detection of the conductive slip ring, and the adjustment component is provided with a detection component for detecting the rotation speed, vibration frequency, and temperature of the conductive slip ring.

[0007] To further explain, the adjustment assembly includes a motor, a rotating block, a connecting frame, an electric telescopic rod, and a lifting block. The motor is connected to the inner side of the upper part of the handle, and the button is electrically connected to the motor. The rotating block is connected to the output shaft of the motor and is rotatably connected to the handle. The connecting frame is connected to the upper front part of the rotating block, and the electric telescopic rod is connected to the connecting frame. The lifting block is connected to the telescopic end of the electric telescopic rod.

[0008] To further explain, the motor and processor are electrically connected via a control module, and the electric telescopic pole and processor are electrically connected via a control module.

[0009] To further explain, the detection component includes a vibration sensor, a speed sensor, a pull rod, a spring, a support rod, and a temperature sensor. The vibration sensor is connected to the lower left side of the lifting block, and the speed sensor is connected to the lower right side of the lifting block. The pull rod is slidably connected to the front of the lifting block, and a spring connects the pull rod to the lifting block. The support rod is slidably connected to the inner front of the lifting block, and the pull rod and the support rod are engaged. The temperature sensor is connected to the lower right side of the support rod.

[0010] To further clarify, the pull rod is T-shaped.

[0011] To further explain, the support rod is L-shaped.

[0012] The present invention has the following advantages: 1. The present invention detects the vibration frequency and rotation speed of the shaft by using a vibration sensor and a speed sensor, and detects the temperature of the rotor of the conductive slip ring by using a temperature sensor. Then, the rotation speed of the conductive slip ring is adjusted to realize the physical signal test at different speeds. Thus, the rotation speed and vibration frequency of the shaft of the conductive slip ring can be detected at the same time as the temperature of the rotor, which facilitates comprehensive detection and evaluation of the operating status and improves the reliability and efficiency of the detection.

[0013] 2. This utility model adjusts the angles of the vibration sensor, speed sensor, and temperature sensor by rotating the rotating block, and then moves the lifting block to make the vibration sensor contact the rotating shaft. Next, the support rod is pulled to move the temperature sensor to contact the rotor and then fix it. This allows the position of the vibration sensor, speed sensor, and temperature sensor to be adjusted for testing purposes. It is easy to adapt to the testing needs of conductive slip rings of different models and structures, and is flexible and convenient to use. Attached Figure Description

Detailed Implementation

[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0020] An instrument for testing signals at different rotational speeds, such as Figures 1-4 As shown, it includes a base 1, suction cups 2, air pumps 3, grips 4, buttons 5, adjustment components, and detection components. The base 1 has two suction cups 2 connected to the left and right sides, and two air pumps 3 connected to the left and right sides. The grips 4 are connected to the upper side of the base 1. The buttons 5 are slidably connected to the front side of the middle part of the grips 4. The upper part of the grips 4 is equipped with an adjustment component for adjusting the detection of the conductive slip ring. The adjustment component is equipped with a detection component for detecting the rotation speed, vibration frequency, and temperature of the conductive slip ring.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the adjustment assembly includes a motor 6, a rotating block 7, a connecting frame 8, an electric telescopic rod 9, and a lifting block 10. The motor 6 is connected to the upper inner side of the handle 4. The motor 6 and the processor are electrically connected through a control module. The button 5 is electrically connected to the motor 6. The rotating block 7 is connected to the output shaft of the motor 6. The rotating block 7 is rotatably connected to the handle 4. The connecting frame 8 is connected to the upper front side of the rotating block 7. The electric telescopic rod 9 is connected to the connecting frame 8. The electric telescopic rod 9 and the processor are electrically connected through a control module. The lifting block 10 is connected to the telescopic end of the electric telescopic rod 9.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, the detection assembly includes a vibration sensor 11, a speed sensor 12, a pull rod 13, a spring 14, a support rod 15, and a temperature sensor 16. The vibration sensor 11 is connected to the lower left side of the lifting block 10, and the speed sensor 12 is connected to the lower right side of the lifting block 10. The pull rod 13 is slidably connected to the front of the lifting block 10. The pull rod 13 is T-shaped for easy hand movement. A spring 14 connects the pull rod 13 and the lifting block 10. The support rod 15 is slidably connected to the inner front of the lifting block 10. The pull rod 13 and the support rod 15 are engaged. The support rod 15 is L-shaped for easy support. The temperature sensor 16 is connected to the lower right side of the support rod 15.

[0023] This device can be used when signal testing of conductive slip rings at different speeds is required. First, pick up the device and place it in the designated position. Then, start the air pump 3. The air pump 3, in conjunction with the suction cup 2, will adhere and fix the device. Next, press button 5 according to the position of the conductive slip ring. The processor, through the control module, will start motor 6. Motor 6 will drive the rotating block 7 to rotate, thereby rotating the vibration sensor 11, speed sensor 12, and temperature sensor 16. After adjusting to the appropriate angle, press button 5 again to turn off motor 6. Then, start the electric telescopic rod 9 on the connecting frame 8. The electric telescopic rod 9 will move the lifting block 10, causing the vibration sensor 11 to contact the rotating shaft on the conductive slip ring. Next, manually pull the pull rod 13 to disengage from the support rod 15, stretching the spring 14. Pulling the support rod 15 will then move the temperature sensor 16 to contact the rotor of the conductive slip ring. Finally, release the pull rod 13, the spring 14 will return, and the pull rod 13 will return to its original position and engage with the support rod 15. The device is fixed in place, with the pull rod 13 being T-shaped and the support rod 15 being L-shaped. This allows for adjustment of the positions of the vibration sensor 11, speed sensor 12, and temperature sensor 16 for testing purposes. This adapts to the testing needs of different models and structures of conductive slip rings, offering flexibility and convenience. The vibration sensor 11 detects the vibration frequency of the rotating shaft, the speed sensor 12 detects the rotation speed of the rotating shaft, and the temperature sensor 16 detects the temperature of the rotor of the conductive slip ring. This enables physical signal testing of the conductive slip ring. By adjusting the rotation speed of the conductive slip ring, physical signal testing at different speeds can be achieved. This allows for simultaneous detection of the rotation speed and vibration frequency of the conductive slip ring's shaft, as well as the temperature of the rotor, facilitating comprehensive evaluation of the operating status and improving the reliability and efficiency of the testing. After testing, the air pump 3 is turned off, and the device is picked up and moved to the next position. The above operation is then repeated to test the next guide slip ring.
