[0003] Chinese patent publication number CN118060216B discloses an automated electrical testing device, including a workbench with a testing section on the top for testing electrical equipment. It also includes testing units located on opposite sides of the workbench, used to alternately transport and test electrical equipment and remove impurities during transport. This solves the problems in existing technologies where impurities on the surface of electrical equipment obstruct the testing area, affecting accuracy, and where manual separation of unqualified and qualified electrical equipment not only fails to separate the equipment but also affects testing efficiency due to varying manual operation speeds. The device removes impurities during testing and automatically separates and collects qualified electrical equipment after testing.

[0013] A method for using an automated testing device for electrical engineering includes the following steps: S1. Start the experimental motor component. The casing begins to vibrate slightly and normally. The pendulum amplifies the back-and-forth vibration, driving the sliding column to move back and forth. Under the action of the one-way valve, the air pressure inside the air cylinder component continuously increases. S2. When the vibration of the casing becomes abnormal and increases, the vent is opened, and the high-pressure air inside the air cylinder cleans the surface of the laser reflector. When the vibration value observed by the laser receiver plate increases, an alarm is issued. S3. When the rotating shaft rotates stably, under the action of centrifugal force, hydraulic pressure, and screw drive, the signal transmitter moves and starts, sending the signal linearly to the trajectory receiving plate and forming a trajectory circle. The diameter of the trajectory circle reflects the rotational speed of the rotating shaft. S4. When the rotating shaft vibrates abnormally, the signal transmitter also vibrates. The trajectory pattern formed by the trajectory receiving plate is approximately elliptical. The shape and size of the ellipse reflect both the rotation speed and the magnitude of the vibration.

[0014] The technical effects and advantages of this invention are as follows: 1. The present invention, by providing a laser vibration measurement component and a venting component, facilitates the use of the housing vibration to drive the venting component to generate high-pressure gas. When the vibration is abnormal, the surface of the laser reflector is automatically cleaned, avoiding dust from affecting the laser vibration measurement, ensuring that the laser receiving board can accurately receive the signal, and enabling the motor vibration optical detection device to maintain monitoring reliability in dusty environments for a long time.

[0015] 2. By incorporating a centrifugal force-bearing component and a distance amplification assembly, this invention facilitates the conversion of changes in the rotational speed of the rotating shaft into changes in the movement distance of the transmission block, thereby affecting the trajectory pattern on the trajectory receiving plate. Normally, the pattern is a circle, and abnormally, it is an ellipse, thus achieving a correspondence and combination between the real-time rotational speed of the motor shaft and the vibration.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The electrical engineering automation testing equipment and method of use involved in the present invention are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Reference Figure 1 , Figure 6 and Figure 7This invention provides an automated testing device for electrical engineering and its usage method, including a support assembly 1. The support assembly 1 includes a support plate 101. An experimental motor component 10 is fixedly connected to the top of the support plate 101. The experimental motor component 10 includes a housing 1001 and a rotating shaft 1002. A laser vibration measuring component 3 is installed on one side of the housing 1001 and is fixedly connected to the support plate 101. A vibration transmission component 4 is installed on the other side of the housing 1001. A venting component 5 is installed on the side of the vibration transmission component 4 away from the housing 1001.

The laser vibration measurement assembly 3 includes a laser emitter 301, the bottom of which is fixedly connected to the support plate 101, a laser reflector 302 is fixedly connected to the side of the housing 1001, and a laser receiver 303 is fixedly connected to the top of the support plate 101. The laser emitted by the laser emitter 301 is reflected by the laser reflector 302 onto the laser receiver 303. The venting assembly 5 includes an air cylinder 501. A trigger block 502 is slidably connected inside the air cylinder 501. A first spring 504 is provided between the trigger block 502 and the air cylinder 501. The two ends of the first spring 504 are fixedly connected to the trigger block 502 and the air cylinder 501, respectively. A sliding rod 503 is fixedly connected to the inner side of the trigger block 502. The first spring 504 is sleeved on the sliding rod 503.

An air outlet 509 is provided on one side of the vent pipe 508, and the air outlet 509 faces the laser reflector 302. In this embodiment, it should be specifically noted that the experimental motor 10 is connected to an external power source, and the external source continuously provides power to the experimental motor 10.

[0020] The main difference between this embodiment and the prior art is that the cleaning force is generated by the vibration of the experimental motor component 10 itself, specifically in the laser vibration measurement component 3, the venting component 5 and the experimental motor component 10. The above structure is the main structure of this embodiment, which solves the problem that the laser vibration measurement component 3 cannot maintain reliability during long-term monitoring. The laser emitter 301 is an existing structure, and the specific structure and connection method of the laser emitter 301 will not be described in detail in this embodiment.

[0021] Reference Figures 1-3The top of the support plate 101 is provided with a T-slot 102 and a clearance frame hole 103. The clearance frame hole 103 is located directly below the rotating shaft 1002. The outer side of the rotating shaft 1002 is provided with a trajectory reaction component 2. The two sides of the rotating shaft 1002 are fixedly connected with a power component 6. One side of the power component 6 is movably connected with a moving component 7. The moving component 7 is fixedly connected to the rotating shaft 1002. The outer side of the rotating shaft 1002 is fixedly connected with a distance amplification component 8. The outer side of the distance amplification component 8 is fixedly connected with a centrifugal force receiving component 9. The distance amplification component 8 is located outside the moving component 7 and is movably connected to the moving component 7.

[0022] In this embodiment, it should be specifically explained that the function of the power component 6 in the device is to transmit motion and change the direction of motion.

[0023] Reference Figure 1 , Figure 3 and Figure 4 The trajectory response component 2 includes a trajectory receiving plate 201, which is fixedly connected to the top of the support plate 101. A signal transmitter 202 is fixedly connected to one side of the moving component 7. The trajectory receiving plate 201 has an avoidance hole inside. The size of the avoidance hole can both avoid the vibration of the rotating shaft 1002 and make the trajectory of the signal transmitter 202 rotate outside the avoidance hole of the trajectory receiving plate 201.

[0024] In this embodiment, it should be specifically explained that when the signal transmitter 202 is started, it sends the signal in a straight line to the trajectory receiving board 201, and a trajectory path is formed on the trajectory receiving board 201.

[0025] Reference Figure 1 , Figure 3 and Figure 7 The vibration transmission assembly 4 includes a vibration transmission plate 401. One end of the vibration transmission plate 401 is fixedly connected to the housing 1001, and the other end of the vibration transmission plate 401 abuts against a pendulum 403. The top of the pendulum 403 is rotatably connected to a fixed shaft 402, and the bottom of the fixed shaft 402 is fixedly connected to a support plate 101. An arc-shaped toothed plate 404 is fixedly connected to the outer side of the bottom of the pendulum 403. A first rack 405 is meshed with the bottom of the arc-shaped toothed plate 404. A T-block 406 is fixedly connected to the bottom of the first rack 405. The T-block 406 is slidably connected to the T-slot 102. One end of a connecting rod 407 is fixedly connected to the outer side of the first rack 405. A sliding column 408 is fixedly connected to the other end of the connecting rod 407. The sliding column 408 is slidably and sealingly connected to the inner wall of the air cylinder component 501.

[0026] In this embodiment, it should be specifically explained that: the housing 1001 begins to vibrate normally and slightly, and the vibration transmission plate 401 also vibrates accordingly. The vibration transmission plate 401 drives the pendulum 403 to rotate around the fixed axis 402. The pendulum 403 amplifies the vibration of the vibration transmission plate 401. The pendulum 403 drives the first rack 405 to move back and forth through the arc-shaped toothed plate 404. The first rack 405 drives the sliding column 408 to move back and forth.

[0027] Reference Figure 6 and Figure 8 The air cylinder component 501 includes an air cylinder body 5011, which is cylindrical. A baffle plate 5012 is fixedly connected to the middle of the air cylinder body 5011. A sliding hole 5013 is provided in the middle of the baffle plate 5012. Multiple air outlet holes 5014 are provided on the outer side of the sliding hole 5013. A sliding rod 503 is slidably connected to the sliding hole 5013. A valve mounting hole 5015 is provided on the unopened side of the air cylinder body 5011 located on the baffle plate 5012. The valve mounting hole 5015 is sealed and connected to a one-way valve 506. A through vent hole 5016 is provided at the bottom of the air cylinder body 5011. The vent hole 5016 is slidably sealed and connected to a baffle block 505. The bottom of the air cylinder body 5011 is fixedly connected to a support plate 101 through a mounting base plate 5017.

[0028] In this embodiment, it should be specifically noted that the outer diameter of the vent hole 5016 is smaller than the inner diameter of the air pipe 507, which facilitates the entry of the high-pressure gas accumulated inside the air cylinder 501 into the air pipe 507.

[0029] Reference Figure 1 , Figure 3 and Figure 4 The power assembly 6 includes a second rack 601, a spur gear 602 meshing with the bottom of the second rack 601, a drive shaft 606 fixedly connected to the center of the spur gear 602, a connecting column 603 rotatably connected to the bottom of the drive shaft 606, the connecting column 603 being fixedly connected to the rotating shaft 1002, a driving bevel gear 604 fixedly connected to one end of the drive shaft 606, and a driven bevel gear 605 meshing with the bottom of the driving bevel gear 604.

[0030] In this embodiment, it should be specifically explained that when the second rack 601 moves, it drives the spur gear 602 to rotate, and the spur gear 602 drives the transmission shaft 606 to rotate, thereby the transmission shaft 606 drives the driving bevel gear 604 to rotate, and the rotation of the driving bevel gear 604 drives the driven bevel gear 605 to rotate.

[0031] Reference Figure 1 , Figure 3 and Figure 4The moving component 7 includes a screw 701, a driven bevel gear 605 fixedly connected to the outer side of the screw 701, a bottom of the screw 701 rotatably connected to the rotating shaft 1002, a sliding block 702 helically connected to the outer side of the screw 701, a guide rod 703 slidably connected to the inner side of the sliding block 702, the guide rod 703 fixedly connected to the rotating shaft 1002, and a support frame 704 rotatably connected to the top of the guide rod 703, the support frame 704 fixedly connected to the rotating shaft 1002.

[0032] In this embodiment, it should be specifically noted that when the driven bevel gear 605 drives the screw 701 to rotate, the sliding block 702 moves away from or closer to the driven bevel gear 605 under the action of the helical transmission.

[0033] Reference Figure 1 , Figure 3 and Figure 5 The distance amplification component 8 includes a large cavity 801. A small cavity 802 is connected through the top of the large cavity 801 away from the centrifugal force-bearing component 9. The inner diameter of the small cavity 802 is smaller than the inner diameter of the large cavity 801. A first sliding block 803 is slidably and sealed inside the large cavity 801. A first telescopic rod 805 is fixedly connected to the bottom of the large cavity 801 via the first sliding block 803. A second spring 804 is sleeved on the outside of the first telescopic rod 805. One end of the second spring 804 is fixedly connected to the first sliding block 803, and the other end of the second spring 804 is fixedly connected to the bottom of the large cavity 801. A second sliding block 802 is slidably and sealed inside the small cavity 802. 06. A transmission block 807 is fixedly connected to the outer side of the second sliding block 806. A part of the transmission block 807 is located on the outer side of the small cavity 802. A third spring 808 is sleeved on the outer side of the transmission block 807. One end of the third spring 808 is fixedly connected to the top of the small cavity 802, and the other end of the third spring 808 is fixedly connected to the second sliding block 806. A retaining ring 809 is fixedly connected to the top of the large cavity 801. The inner diameter of the retaining ring 809 is smaller than the outer diameter of the second sliding block 806, which restricts the second sliding block 806 from entering the large cavity 801. The first sliding block 803 divides the large cavity 801 into two cavities: a liquid storage left cavity 810 and a liquid storage right cavity 811.

[0034] In this embodiment, it should be specifically explained that when the hydraulic oil inside the centrifugal force-bearing component 9 enters the left reservoir cavity 810, the amount of oil inside the left reservoir cavity 810 increases, which compresses the first sliding block 803 to move towards the retaining ring 809, and the second spring 804 also extends accordingly. The hydraulic oil inside the right reservoir cavity 811 compresses the second sliding block 806 and the transmission block 807 to move outward. Because the inner diameter of the large cavity 801 is larger than the inner diameter of the small cavity 802, the distance that the transmission block 807 extends is also amplified.

[0035] Reference Figure 1 , Figure 3 and Figure 5The centrifugal force-bearing component 9 includes a cylinder body 901. The bottom of the cylinder body 901 is fixedly connected to the rotating shaft 1002. A third sliding block 904 is slidably and sealed inside the cylinder body 901. A second telescopic rod 903 is fixedly connected to the side of the third sliding block 904 away from the oil pipe 906. An oil passage chamber 905 is provided on the other side of the third sliding block 904. The oil passage chamber 905 is connected to the left liquid storage chamber 810 through the oil pipe 906. The second telescopic rod 903 is fixedly connected to the bottom of the cylinder body 901. A fourth spring 902 is sleeved on the outside of the second telescopic rod 903. One end of the fourth spring 902 is fixedly connected to the bottom of the cylinder body 901, and the other end of the fourth spring 902 is fixedly connected to the third sliding block 904.

[0036] In this embodiment, it should be specifically explained that when the rotating shaft 1002 rotates steadily and continuously, the third sliding block 904 is subjected to centrifugal force, and the third sliding block 904 compresses the hydraulic oil inside the oil passage 905 into the liquid storage left cavity 810 through the oil passage pipe 906.

[0037] Working principle of the invention: The main problem solved in this embodiment is to achieve self-cleaning when the vibration of the experimental motor component 10 is abnormal, and to combine motor shaft speed measurement and vibration measurement by utilizing the centrifugal force generated when the motor shaft rotates and the vibration force of the abnormal vibration of the motor shaft.

[0038] The specific steps are as follows: First, the experimental motor 10 is started, and the housing 1001 begins to vibrate slightly. The vibration transmission plate 401 also vibrates accordingly. The vibration transmission plate 401 drives the pendulum 403 to rotate around the fixed axis 402. The pendulum 403 amplifies the vibration of the vibration transmission plate 401. The pendulum 403 drives the first rack 405 to move back and forth through the arc-shaped toothed plate 404. The first rack 405 drives the sliding column 408 to move back and forth. When the sliding column 408 moves away from the trigger block 502, a negative pressure is generated inside the air cylinder 501. Air from outside the air cylinder 501 enters through the one-way valve 506. When the sliding column 408 approaches the trigger block 502, it compresses the gas. Thus, under the action of the one-way valve 506, the air pressure inside the air cylinder 501 continuously increases. When the vibration of the housing 1001 increases, the sliding column 408 presses the trigger block 502, causing the vent 5016 to open. The high-pressure air inside the air cylinder 501 rushes out from the air outlet 509 through the air pipe 507 to clean the surface of the laser reflector 302. As the vent 5016 is continuously opened, the surface of the laser reflector 302 is continuously cleaned. When the housing 1001 vibrates abnormally, the vibration increases, and the position change of the laser emitted by the laser emitter 301 received by the laser receiver 303 increases. It can be seen that the observed vibration value increases. Since the surface of the laser reflector 302 is continuously cleaned to avoid inaccurate vibration data measurement due to dust, an alarm is issued at this time. When the rotating shaft 1002 rotates stably, the third sliding block 904 moves under the action of centrifugal force, forcing the hydraulic oil inside the oil passage 905 to enter the left reservoir 810 through the oil passage pipe 906. The amount of oil inside the left reservoir 810 increases, forcing the first sliding block 803 to move towards the retaining ring 809. The second spring 804 also extends accordingly. The hydraulic oil inside the right reservoir 811 forces the second sliding block 806 and the transmission block 807 to move outward. Because the inner diameter of the large cavity 801 is greater than... The inner diameter of the small cavity 802 increases the extension distance of the transmission block 807, causing the third spring 808 to contract. The second rack 601 then moves, driving the spur gear 602 to rotate. The spur gear 602, in turn, drives the transmission shaft 606 to rotate, which in turn drives the driving bevel gear 604 to rotate. The rotation of the driving bevel gear 604 drives the driven bevel gear 605 to rotate, which in turn drives the screw 701 to rotate. The sliding block 702 plays a role in the screw drive... When the driven bevel gear 605 moves away from the center, the signal transmitter 202 is activated, sending a signal linearly to the trajectory receiver plate 201. A trajectory circle is formed on the trajectory receiver plate 201. When the rotational speed of the rotating shaft 1002 increases or decreases, the centrifugal force increases or decreases, resulting in more or less hydraulic oil entering the left reservoir 810. Consequently, the extension length of the transmission block 807 increases or decreases, causing the sliding block 702 to move a greater or less distance. Therefore, the diameter of the trajectory circle on the trajectory receiver plate 201 also increases or decreases. Thus, the diameter of the trajectory circle on the trajectory receiver plate 201 reflects the rotational speed of the rotating shaft 1002. When the rotating shaft 1002 vibrates abnormally, the screw 701 and guide rod 703 also vibrate abnormally, and the signal transmitter 202 also vibrates. The trajectory pattern formed by the trajectory receiver plate 201 is no longer circular but approximately elliptical. The shape and size of the ellipse simultaneously reflect the abnormal state of the rotational speed and vibration. If the vibration is abnormal, an alarm is issued.
