Description

Technical Field

[0001] This invention relates to the field of electric actuator testing technology, specifically to an electric actuator testing system. Background Technology

[0002] An electric actuator is a mechanism driven by electricity, used to control, regulate, or automate mechanical motion in various industrial processes. It can convert input electrical energy into mechanical kinetic energy and, together with valves, forms an electric regulating valve to complete various control tasks. It is widely used in chemical, petroleum, metallurgy, power, water treatment and other fields.

[0003] Currently, electric actuators are mainly connected to supporting equipment through multiple sets of terminals. After production, electric actuators need to be tested, usually manually using a multimeter to test their electrical performance. While this method can detect the electrical performance of the electric actuator, it has certain limitations: During storage, the terminals of electric actuators are prone to showing a power failure due to minor issues such as dust and impurities adhering to them, which can lead to incorrect judgment of test results. Electric actuators have a large number of terminals, and manually testing them with a multimeter is inefficient. The torque of an electric actuator is the torque required to drive the load. If it is not monitored, it is prone to overload damage, which can lead to malfunctions in equipment equipped with electric actuators.

[0004] Patent application number 201010589721.2 discloses a comprehensive testing device for electric actuators, including torque, stroke, and remote control function testing. The invention includes a cabinet, driving and driven shafts, a large bevel gear, a small bevel gear, a semi-circular ring, a magnetic powder brake, a programmable power supply, a reaction force torque sensor, and a rotary encoder. This invention achieves comprehensive testing of electric actuators, including torque and position accuracy testing, and remote control function testing. It can not only digitize and automate the factory testing of electric actuators, automatically generating factory test reports, but also provide type testing for new products to nationally designated industry testing institutions. Its accuracy and stability are very high, and it greatly reduces manual intervention, improving the level of automation in testing and increasing production efficiency. However, it lacks a structure for treating dust on the terminals of the electric actuator, thus failing to avoid errors in electrical performance test results due to dust adhesion to the terminals.

[0005] Therefore, we proposed a testing system for electric actuators to address the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a testing system for electric actuators, in order to solve the problem mentioned in the background art that during the storage of electric actuators, the terminals are prone to showing power failure due to minor issues such as dust and impurities adhering to them, which leads to incorrect judgment of test results.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an electric actuator testing system, including a test bench, a rotating mechanism being provided on the top of the test bench, a cleaning mechanism for cleaning the electric actuator and a first detection mechanism for detecting the electrical performance being installed in the rotating mechanism, and a docking mechanism for contacting the mobile electric actuator with the rotating mechanism, a second detection mechanism for detecting the torque and a counterweight mechanism being provided on the test bench; The rotating mechanism includes a control column and a drive mechanism for rotating the control column, and a first mounting hole is provided on the surface of the control column; The cleaning mechanism includes a drive motor and a brush.

[0008] Furthermore, the transmission device consists of a transmission pulley fixedly connected to the brush and a transmission belt with one end sleeved on the transmission pulley, and the other end of the transmission belt sleeved on a drive pulley fixedly connected to the output end of the drive motor.

[0009] Furthermore, the cleaning mechanism has multiple brushes and multiple transmission pulleys. Each transmission pulley has a first rotating shaft fixedly connected to its front side. A first bearing is fixedly connected to the outer surface of the first rotating shaft. There are multiple first mounting holes, and multiple first bearings are fixedly installed inside the first mounting holes. The transmission belt includes a second transmission belt and a third transmission belt. The second transmission belt is installed between the outer surfaces of adjacent transmission pulleys, and multiple second transmission belts are arranged in an alternating manner. The third transmission belt is installed between the outer surface of the drive pulley and one of the transmission pulleys.

[0010] Furthermore, the docking mechanism includes a bracket fixedly connected to the bottom of the test bench, and a surrounding plate fixedly connected to the top of the test bench near its edge; a first cylinder is fixedly installed on the rear surface of the surrounding plate, the telescopic end of the first cylinder slides through the outer surface of the surrounding plate and extends to the front side, and a positioning sleeve for placing an electric actuator is fixedly connected to the telescopic end of the first cylinder, the bottom of the positioning sleeve being slidably connected to the top of the test bench.

[0011] Furthermore, the driving mechanism is a stepper motor, which is fixedly installed on the top of the test bench near the front. The output end of the stepper motor slides through the test bench and is fixedly connected to a small pulley. A connecting column is fixedly connected to the bottom of the control column. The outer surface of the connecting column slides through the top of the test bench and extends downwards. A large pulley is fixedly connected to the bottom of the connecting column. A first transmission belt is installed between the outer surfaces of the large pulley and the small pulley.

[0012] Furthermore, the first detection mechanism includes multiple connecting plates, which are equidistantly fixedly installed on the front surface of the control column. Detection heads are symmetrically fixedly connected to the front surfaces of the connecting plates near both ends. A first connecting line is electrically connected to the outer surface of one of the detection heads, and a second connecting line is electrically connected to the outer surface of the other detection head.

[0013] Furthermore, a controller is electrically connected between the end faces of the first and second connecting lines, and an indicator light is electrically connected to the rear surface of the controller. The controller is fixedly mounted on the outer surface of one side of the control column.

[0014] Furthermore, the second testing mechanism includes a mounting plate, which is fixedly connected to the top of the test bench near the rear edge. A second cylinder is fixedly installed on one side of the outer surface of the mounting plate near the front. The telescopic end of the second cylinder slides through the outer surface of the mounting plate and extends to the other side. A third bearing is fixedly connected to the outer surface of the telescopic end of the second cylinder. A circular sleeve is fixedly connected to the outer surface of the third bearing. A claw plate seat is fixedly welded to the end face of the circular sleeve. A claw plate body is fixedly installed on the outer surface of the claw plate seat.

[0015] Furthermore, the counterweight mechanism includes two guide wheels and a storage sleeve. A counterweight block is placed inside the storage sleeve. A second rotating shaft is fixedly connected to the rear surface of each of the two guide wheels. A fourth bearing is fixedly connected to the outer surface of the second rotating shaft. The fourth bearing is fixedly connected inside the mounting plate.

[0016] Furthermore, pull lines are provided on the outer surfaces of the two guide wheels near the top, and hooks are provided at both ends of the pull lines. A first hanging ring is fixedly connected to the outer surface of the circular sleeve, and a second hanging ring is fixedly connected to the top of the counterweight. The first and second hanging rings respectively cooperate with the two hooks.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. By starting the first cylinder, the electric actuator in the positioning sleeve is pushed close to the brush. Then, the drive motor is started by the external control device, which drives the drive pulley to rotate at high speed. At this time, the third transmission belt on the surface of the drive pulley drives one of the transmission pulleys to rotate at high speed. Under the action of the second transmission belt, all the transmission pulleys start to rotate at high speed, which causes the brush to rotate. The rotating brush sweeps away the dust on the terminal surface of the electric actuator, thus avoiding the problem of incorrect power-on performance test results caused by dust adhering to the terminal.

[0018] 2. By starting the stepper motor, the small pulley at the bottom of the test bench can be rotated. In conjunction with the first transmission belt, the large pulley can be slowly rotated 180°, so that the detection end faces the wiring terminal of the electric actuator, and each set of detection ends corresponds to each set of wiring terminals. At this time, by starting the first cylinder, the positioning sleeve and the electric actuator are moved forward again, so that the wiring terminal on the electric actuator is in contact with the detection end, making each set of detection ends connected. This allows the corresponding controller to detect the electrical signal and control the indicator light to light up. When the internal circuit of a certain set of wiring terminals is broken, the corresponding detection end cannot be connected, so the indicator light on the corresponding controller will not light up. When the controller receives intermittent current, the corresponding indicator light will flash, thus quickly judging the power-on performance of the electric actuator. This design can significantly improve the detection efficiency of power-on performance and obtain detailed power-on information.

[0019] 3. When it is necessary to test the torque of the electric actuator, the second cylinder is activated to push the claw plate seat towards the electric actuator, thereby pushing the claw plate body into the rotor of the electric actuator. Then, when the electric actuator is activated to control the rotor to rotate, it will drive the claw plate body to rotate synchronously. Since the first and second hanging rings are connected to the two hooks, when the claw plate body rotates, the circular sleeve on the claw plate seat will wind up one end of the pull cable and pull the counterweight at the other end of the pull cable upward. Whether the counterweight moves upward can be used to determine whether the torque of the electric actuator is qualified. This avoids the problem of the supporting equipment being prone to failure after the electric actuator with insufficient torque is put into use, and reduces safety hazards.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0023] like Figures 1-8As shown, the present invention provides an electric actuator testing system, including a test bench 1. A rotating mechanism 3 is arranged on the top of the test bench 1 near the front side. A cleaning mechanism 4 is arranged on the rear side of the rotating mechanism 3. A first detection mechanism 5 is arranged on the front side of the rotating mechanism 3. A second detection mechanism 6 is arranged on the top of the test bench 1 near the rear side. A counterweight mechanism 7 is arranged on one side of the second detection mechanism 6. The rotating mechanism 3 includes a control column 301 and a stepper motor 306. A plurality of first mounting holes 302 are equidistantly opened on the rear surface of the control column 301. The cleaning mechanism 4 includes a drive motor 401 and a plurality of brushes 406. A transmission pulley 404 is fixedly mounted on the front side of the plurality of brushes 406. A first rotating shaft 405 is fixedly connected to the front side of the transmission pulley 404. A first bearing 403 is fixedly connected to the outer surface of the first rotating shaft 405. A plurality of first bearings 403 are fixedly mounted on the first rotating shaft 405. Inside a mounting hole 302, a second transmission belt 407 is installed between the outer surfaces of adjacent transmission pulleys 404. Multiple second transmission belts 407 are arranged in an alternating pattern. A drive motor 401 is fixedly installed on the top of the control column 301 near the rear side. A drive pulley 402 is fixedly connected to the output end of the drive motor 401. A third transmission belt 408 is installed between the outer surfaces of the drive pulley 402 and one of the transmission pulleys 404. A bracket 11 is fixedly connected to the bottom of the test bench 1. A surrounding plate 12 is fixedly connected to the top of the test bench 1 near the edge. A first cylinder 2 is fixedly installed on the rear surface of the surrounding plate 12. The telescopic end of the first cylinder 2 slides through the outer surface of the surrounding plate 12 and extends to the front side. A positioning sleeve 21 is fixedly connected to the telescopic end of the first cylinder 2. The bottom of the positioning sleeve 21 is slidably connected to the top of the test bench 1. An electric actuator is placed inside the positioning sleeve 21.

[0024] The overall effect of Embodiment 1 is as follows: When testing the energization status of the electric actuator, it is placed in the positioning sleeve 21, and then the first cylinder 2 is activated to push the electric actuator in the positioning sleeve 21 closer to the brush 406. Then, the drive motor 401 is started by the external control device, causing the drive pulley 402 to rotate at high speed. At this time, the third transmission belt 408 on the surface of the drive pulley 402 drives one of the transmission pulleys 404 to rotate at high speed. Under the action of the second transmission belt 407, all the transmission pulleys 404 begin to rotate at high speed, causing the brush 406 to rotate accordingly. The rotating brush 406 sweeps away the dust from the surface of the terminals on the electric actuator, thus avoiding the problem of incorrect energization performance test results caused by dust adhering to the terminals. The test platform 1 is used to support the function of this device, and the control column 301 is internally equipped with... A power supply is provided to power electrical components such as the drive motor 401. The first bearing 403 is installed inside the first mounting hole 302 on the surface of the control column 301, and the transmission pulley 404 is installed on the surface of the control column 301 through the first bearing 403 and the first rotating shaft 405. This allows the transmission pulley 404 to rotate smoothly, reducing the resistance to the drive shaft of the drive motor 401, thus reducing power loss. Two belt grooves are opened on the surface of each transmission pulley 404, mainly for staggered installation of the first transmission belt 305 so that all transmission pulleys 404 can be linked. The enclosure 12 on the top of the test bench 1 can shield some of the dust and impurities splashed during the cleaning process. The bracket 11 is mainly used to raise the device. The entire bracket 11 is made of multiple angle steel welded together, which is low in cost, and is connected to the test bench 1 by bolts. Example 2

[0025] Based on Example 1, further, such as Figures 1-8As shown, a stepper motor 306 is fixedly installed on the top of the test bench 1 near the front. The output end of the stepper motor 306 slides through the top of the test bench 1 and extends downwards. A small pulley 307 is fixedly connected to the output end of the stepper motor 306. A connecting post 303 is fixedly connected to the bottom of the control post 301. The outer surface of the connecting post 303 slides through the top of the test bench 1 and extends downwards. A large pulley 304 is fixedly connected to the bottom of the connecting post 303. A first transmission belt 305 is installed between the outer surfaces of the large pulley 304 and the small pulley 307. The first detection mechanism 5 includes multiple connecting plates 501. Multiple connecting plates 501 are fixedly installed at equal intervals on the front surface of the control column 301. Detection heads 502 are symmetrically fixedly connected to the front surface of the connecting plates 501 near both ends. A first connecting line 503 is electrically connected to the outer surface of one detection head 502, and a second connecting line 504 is electrically connected to the outer surface of the other detection head 502. A controller 505 is electrically connected between the end faces of the first connecting line 503 and the second connecting line 504. An indicator light 506 is electrically connected to the rear surface of the controller 505. The controller 505 is fixedly installed on one side of the outer surface of the control column 301.

[0026] The effect achieved by the entire embodiment 2 is as follows: after the dust on the surface of the wiring terminal of the electric actuator is cleaned, the stepper motor 306 is started to drive the small pulley 307 at the bottom of the test bench 1 to rotate. Since the diameter of the small pulley 307 is smaller than that of the large pulley 304, it, in conjunction with the first transmission belt 305, can drive the large pulley 304 to rotate slowly by 180°, thereby making the detection end 502 face the wiring terminal of the electric actuator, and each set of detection ends 502 corresponds to each set of wiring terminals. At this time, the first cylinder 2 is started again to drive the positioning sleeve 21 and the electric actuator forward, thereby making the wiring terminal on the electric actuator fit with the detection end 502, so that each set of detection ends 502 forms a connected state, thereby allowing the corresponding controller 505 to detect the electrical signal and control the pointer. Indicator light 506 illuminates. When the internal circuit of a certain set of terminals is open, the corresponding detection terminal 502 will not be connected. Therefore, indicator light 506 on the corresponding controller 505 will not illuminate. When the controller 505 receives intermittent current, the corresponding indicator light 506 will flash, thus quickly determining the power-on performance of the electric actuator. This design can significantly improve the detection efficiency of power-on performance and obtain detailed power-on information. Connecting post 303 is mainly used to connect control post 301 and large pulley 304, so that control post 301 can rotate with large pulley 304. Connecting plate 501 is made of plastic and has non-conductive properties. Other materials can be replaced according to actual conditions. Controller 505 is mainly powered by the internal power supply of control post 301. Example 3

[0027] Based on Example 1, further, such as Figures 1-8 As shown, the second testing mechanism 6 includes a mounting plate 601, which is fixedly connected to the top of the test bench 1 near the rear edge. A second cylinder 602 is fixedly installed on one side of the outer surface of the mounting plate 601 near the front. The telescopic end of the second cylinder 602 slides through the outer surface of the mounting plate 601 and extends to the other side. A third bearing 603 is fixedly connected to the outer surface of the telescopic end of the second cylinder 602. A circular sleeve 606 is fixedly connected to the outer surface of the third bearing 603. A claw plate seat 604 is fixedly welded to the end face of the circular sleeve 606. A claw plate body 605 is fixedly installed on the outer surface of the claw plate seat 604. Example 4

[0028] Based on embodiment 3, the counterweight mechanism 7 further includes two guide wheels 706 and a storage sleeve 701. A counterweight block 702 is placed inside the storage sleeve 701. A second rotating shaft 705 is fixedly connected to the rear surface of each of the two guide wheels 706. A fourth bearing 704 is fixedly connected to the outer surface of the second rotating shaft 705. The fourth bearing 704 is fixedly connected inside the mounting plate 601. Example 5

[0029] Based on embodiment 4, further, a pull line 703 is provided on the outer surface of the two guide wheels 706 near the upper position, and hooks 707 are provided at both ends of the pull line 703. A first hanging ring 607 is fixedly connected to the outer surface of the circular sleeve 606, and a second hanging ring 708 is fixedly connected to the top of the counterweight block 702. The first hanging ring 607 and the second hanging ring 708 respectively cooperate with the two hooks 707.

[0030] The overall effect of embodiments 3, 4, and 5 is that when the torque of the electric actuator needs to be detected, the second cylinder 602 is activated to push the claw plate seat 604 towards the electric actuator, thereby pushing the claw plate body 605 into the wheel of the electric actuator. Then, when the electric actuator is activated to control the wheel to rotate, it will drive the claw plate body 605 to rotate synchronously. Since the first hanging ring 607 and the second hanging ring 708 are connected to the two hooks 707, when the claw plate body 605 rotates, the circular sleeve 606 on the claw plate seat 604 winds up one end of the pull cable 703 and pulls the counterweight 702 at the other end of the pull cable 703 upwards. Whether the counterweight 702 moves upwards can be used to determine whether the torque of the electric actuator is qualified. This avoids the problem of insufficient torque causing equipment failure after the electric actuator is put into use, reducing safety hazards. (Mounting plate 60) 1. Primarily used for mounting the second cylinder 602 and the fourth bearing 704. The circular sleeve 606 is connected to the output end of the second cylinder 602 via the third bearing 603. Therefore, when the claw plate body 605 drives the claw plate seat 604 to rotate, the circular sleeve 606 will rotate along with the claw plate seat 604. Two guide wheels 706 are provided to support and guide the pull cable 703. Since the second rotating shaft 705 and the mounting plate 601 are connected via the fourth bearing 704, the guide wheel 706 on the end face of the second rotating shaft 705 can rotate smoothly without causing significant frictional resistance to the pull cable 703. The storage sleeve 701 is mainly used to place the counterweight 702. The counterweight 702 and the pull cable 703 are connected via hooks 707 and second hanging rings 708. Therefore, disassembly and assembly are simple, and it is convenient to replace the counterweight 702 of different weights to detect the torque of the electric actuator.

[0031] The usage and working principle of this device are as follows: When detecting the energization status of the electric actuator, it is placed in the positioning sleeve 21. Then, the first cylinder 2 is activated to push the electric actuator in the positioning sleeve 21 closer to the brush 406. Subsequently, the drive motor 401 is started by the external control device, which drives the drive pulley 402 to rotate at high speed. At this time, the third transmission belt 408 on the surface of the drive pulley 402 drives one of the transmission pulleys 404 to rotate at high speed. Under the action of the second transmission belt 407, all the transmission pulleys 404 start to rotate at high speed, thereby causing the brush 406 to rotate accordingly. The rotating brush 406 sweeps away the dust on the surface of the terminals on the electric actuator, thus preventing the connection from being damaged. The problem of erroneous electrical performance test results due to dust adhering to the terminals is addressed by the following: After cleaning the dust from the terminals of the electric actuator, starting the stepper motor 306 drives the small pulley 307 at the bottom of the test bench 1 to rotate. Since the diameter of the small pulley 307 is smaller than that of the large pulley 304, it, in conjunction with the first transmission belt 305, drives the large pulley 304 to slowly rotate 180°, thus aligning the test terminal 502 with the terminals of the electric actuator. Each set of test terminals 502 corresponds to each set of terminals. At this point, starting the first cylinder 2 again moves the positioning sleeve 21 and the electric actuator forward, thus aligning the terminals on the electric actuator with the test terminals 502. The fit ensures that each set of detection terminals 502 is connected, allowing the corresponding controller 505 to detect the electrical signal and control the indicator light 506 to illuminate. If the internal circuit of a certain set of terminals is open, the corresponding detection terminal 502 will not be connected, and therefore the indicator light 506 on the corresponding controller 505 will not illuminate. When the controller 505 receives intermittent current, the corresponding indicator light 506 will flash, allowing for quick assessment of the electric actuator's energizing performance. This design significantly improves the efficiency of energizing performance detection, providing detailed energizing information. When the torque of the electric actuator needs to be detected, the second cylinder 602 is activated to push the claw plate seat 6. 04. Move towards the electric actuator, thereby pushing the claw plate body 605 into the rotor of the electric actuator. When the electric actuator is started to control the rotor to rotate, it will drive the claw plate body 605 to rotate synchronously. Since the first hanging ring 607 and the second hanging ring 708 are connected to the two hooks 707, when the claw plate body 605 rotates, the circular sleeve 606 on the claw plate seat 604 winds up one end of the pull cable 703 and pulls the counterweight 702 at the other end of the pull cable 703 upward. Whether the counterweight 702 moves upward can be used to determine whether the torque of the electric actuator is qualified. This avoids the problem of the supporting equipment being prone to failure after the electric actuator with insufficient torque is put into use, and reduces safety hazards.

[0032] The wiring diagrams of the first cylinder 2, stepper motor 306, drive motor 401, controller 505, indicator light 506, and second cylinder 602 in this invention are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the first cylinder 2, stepper motor 306, drive motor 401, controller 505, indicator light 506, and second cylinder 602 will not be explained in detail.
