Description

Technical Field

[0001] This utility model relates to the field of industrial automation testing technology, specifically a multi-sensor fusion motor speed test bench. Background Technology

[0002] In the field of modern industrial automation and intelligent manufacturing, the precise measurement and control of the motor's speed, as a core power output device, directly affects the system's operating efficiency, stability, and reliability. From traditional manufacturing to high-end equipment manufacturing industries such as new energy vehicles and aerospace, the development of motor speed testing technology has always been a key link in improving equipment performance and production quality. However, existing multi-sensor fusion motor speed test benches still have some problems in use: First, existing motor speed test benches generally require manual alignment of the motor with the test end. This manual alignment is not precise enough, and the motor is prone to shifting during the test, which affects the accuracy of the test structure. Secondly, the anti-slip pads connected to the positioning plate on the existing test bench are generally installed in a fixed manner. Since different motors have different shapes and specifications, in order to better fix the motor to be tested, it is necessary to replace them with suitable anti-slip pads. The fixed installation method is not conducive to the quick replacement of anti-slip pads, which reduces the practicality of the test bench structure. Utility Model Content

[0003] To address the issues of inaccurate alignment between the existing test bench and the test end, which relies on manual movement, and the inability to quickly replace the appropriate anti-slip pads based on the actual shape of the test motor, this invention aims to provide a multi-sensor fusion motor speed test bench.

[0005] Preferably, the connecting assembly includes a plug plate, which is fixedly installed on the upper surface of the anti-slip pad. The upper surface of the positioning plate is provided with a slot for use with the plug plate. The plug plate is inserted into the slot, and an anti-loosening bolt is threaded between the plug plate and the positioning plate.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Example: Figure 1-3 As shown, this utility model provides a multi-sensor fusion motor speed test bench, including a test bench body 1. The test bench body 1 serves as a basic load-bearing structure, providing a stable mounting platform for various functional components. A vertical plate 5 and a sensor body 8 are respectively installed on the upper surface of the test bench body 1. A load simulator 4 is installed on one side of the vertical plate 5. The vertical plate 5 and the load simulator 4 cooperate to simulate the load changes under the actual operating conditions of the motor. The sensor body 8 and the load simulator 4 are connected by a coupling. The sensor body 8 is connected to the load simulator 4 through the coupling to ensure that the motor speed signal can be accurately transmitted to the sensor. The three work together to construct a complete motor speed test environment to meet the test requirements under different operating conditions.

[0014] The upper surface of the test bench body 1 is provided with an adjustment component 2, and a positioning plate 7 is slidably mounted on the upper surface of the adjustment component 2. The setting of the adjustment component 2 enables precise adjustment of the position of the positioning plate 7. Compared with the traditional manual adjustment method, it can effectively improve the coaxiality accuracy of the motor installation. Through the precise control of the position of the positioning plate 7 by the adjustment component 2, the coaxiality error between the motor and the sensor body 8 and the load simulator 4 can be controlled within a very small range, reducing the measurement error caused by installation deviation, thereby significantly improving the accuracy and reliability of the test results. An anti-slip pad 6 is movably mounted on one side of the positioning plate 7. A connecting component 3 is provided between the anti-slip pad 6 and the positioning plate 7. The design of the connecting component 3 makes the replacement operation of the anti-slip pad 6 convenient and efficient, avoiding the time-consuming and labor-intensive problem of replacing the anti-slip pad 6 under the traditional fixed installation method. This greatly improves the adaptability of the test bench to different motors and effectively enhances the practicality of the test bench structure.

[0015] The adjustment component 2 includes a first cylinder 25, which is fixedly installed on the upper surface of the test bench body 1. The output end of the first cylinder 25 is fixedly connected to a mounting base 23, and the lower surface of the mounting base 23 is slidably connected to the test bench body 1. The first cylinder 25 enables linear sliding adjustment of the mounting base 23 on the test bench body 1. A second cylinder 24 is fixedly installed inside the mounting base 23, and the output end of the second cylinder 24 is fixedly connected to a support platform 201. The second cylinder 24 can drive the support platform 201 to move up and down. During the motor installation process, the height of the support platform 201 can be quickly adjusted according to the height requirements of different motors, so that the motor is better aligned with the sensor body 8 and the load simulator 4 in the vertical direction, further improving the coaxiality accuracy of the motor installation, reducing measurement errors caused by height deviation, and enhancing the accuracy of the test.

[0016] A servo motor 21 is fixedly connected to one side of the support platform 201. A support base 22 for use with the servo motor 21 is fixedly installed on one side of the support platform 201. The servo motor 21 is fixedly installed on the upper surface of the support base 22, which provides a stable mounting position for the servo motor 21. The output end of the servo motor 21 passes through the support platform 201 and is fixedly connected to a bidirectional screw 29. The servo motor 21 drives the bidirectional screw 29 to rotate, enabling high-precision position adjustment. A slider 27 is threaded onto the outer surface of the bidirectional screw 29. The slider 27 is threaded in the opposite direction of the thread on the outer surface of the bidirectional screw 29. The slider 27 is slidably connected to the inside of the support platform 201. The threads of the bidirectional screw 29 and the slider 27 engage, allowing for precise position adjustment. Driven by motor 21, the two sliders 27 can move synchronously in opposite or the same direction. A limiting shell 26 for use with the slider 27 is fixedly installed inside the support platform 201. The bidirectional screw 29 passes through the limiting shell 26 and does not contact the limiting shell 26. The limiting shell 26 limits the sliding of the slider 27 to prevent the slider 27 from disengaging from the bidirectional screw 29. A connecting rod 28 is fixedly connected to one side of the slider 27. The top end of the connecting rod 28 is fixedly connected to the positioning plate 7. The connecting rod 28 transmits the movement of the slider 27 to the positioning plate 7, so that the positioning plate 7 can follow the slider 27 to make precise position adjustments, achieve the effect of centering and fixing the test motor, ensure good docking between the motor and the sensor body 8 and the load simulator 4, and improve the accuracy and reliability of speed testing.

[0017] The connecting component 3 includes a plug plate 32, which is fixedly installed on the upper surface of the anti-slip pad 6. The upper surface of the positioning plate 7 is provided with a slot 31 for use with the plug plate 32. The plug plate 32 and the slot 31 are plugged in and engaged. The plugging and engaging of the plug plate 32 and the slot 31 enables the quick installation and disassembly of the anti-slip pad 6 and the positioning plate 7.

[0018] The insert plate 32 is a magnetic plate, and the slot 31 is a magnetic groove. The insert plate 32 and the slot 31 are magnetically connected. This magnetic connection between the insert plate 32 and the slot 31 enables quick installation while providing a certain connection and fastening force to prevent the anti-slip pad 6 from loosening or shifting due to vibration or other factors during motor testing. The insert plate 32 and the positioning plate 7 are connected by a threaded anti-loosening bolt 33. The anti-loosening bolt 33 further enhances the connection strength between the insert plate 32 and the positioning plate 7, preventing loosening between the insert plate 32 and the positioning plate 7 under conditions of long-term motor operation vibration or frequent replacement of the anti-slip pad 6. This allows for quick replacement of the appropriate anti-slip pad 6 on the test bench structure according to actual conditions, effectively improving the practicality of the test bench structure.

[0019] Working principle: First, select a suitable anti-slip pad 6 according to the motor's shape and specifications. Then, use the connecting component 3 to magnetically connect the insert plate 32 on the anti-slip pad 6 to the slot 31 on the positioning plate 7, and use the magnetic attraction to achieve quick initial fixation.

[0020] Then, the insert plate 32 and the positioning plate 7 are threadedly fastened together by the anti-loosening bolt 33 to ensure that the anti-slip pad 6 is installed securely and to provide reliable anti-slip support for the motor.

[0021] Then, the motor to be tested is placed on the support platform 201 between the two positioning plates 7, and the servo motor 21 in the adjustment component 2 is started. The servo motor 21 is installed on the support base 22, and its output end drives the bidirectional screw 29 to rotate.

[0022] Since the slider 27 is threaded on the opposite thread direction of the outer surface of the bidirectional screw 29, and the slider 27 slides in cooperation with the limiting shell 26 inside the support platform 201, when the bidirectional screw 29 rotates, the two sliders 27 slide precisely in opposite or the same direction under the guidance of the limiting shell 26. Through the connecting rod 28, the anti-slip pad 6 connected to the positioning plate 7 moves to center and clamp the test motor on the support platform 201.

[0023] Next, the second cylinder 24 is started, and its output end pushes the support platform 201 to rise and fall vertically, adjusting the height position of the motor in the vertical direction.

[0024] Then, the first cylinder 25 is activated, and its output end pushes the mounting base 23 to slide along the preset slide rail on the upper surface of the test bench body 1, thereby driving the positioning plate 7 and the motor to make a rough adjustment in the horizontal direction. Through the coordinated action of the first cylinder 25 and the second cylinder 24, the motor shaft is precisely aligned with the coupling between the sensor body 8 and the load simulator 4, ensuring that the coaxiality of the motor installation meets the test requirements.

[0025] After the motor position is precisely adjusted, the load simulator 4 is started to simulate the load under the actual operating conditions of the motor. After the motor starts running, its speed signal is transmitted to the sensor body 8 through the coupling. The multi-sensor fusion system in the sensor body 8 collects and processes the speed signal to complete the motor speed test.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
