Description

Technical Field

[0001] This invention relates to the field of motor testing technology, specifically a device for testing the vibration resistance of motors. Background Technology

[0002] Seismic performance testing of motors is an important means of evaluating whether a motor can operate normally and maintain structural integrity under vibration environments such as earthquakes. It assesses structural reliability, tests the strength and stability of the motor's mechanical structure under vibration conditions, and determines whether it can withstand the expected seismic load, preventing situations such as motor casing cracking, loosening or damage of internal parts, etc. A vibration table is usually used to simulate the vibration generated during an earthquake. The vibration table can generate vibration waveforms with different frequencies, amplitudes and accelerations. The motor is installed on the vibration table and tested according to predetermined vibration conditions. During the test, the performance of the motor under different vibration states is measured by sensors and other instruments.

The device includes a horizontally positioned support plate and at least one test base mounted on the top wall of the support plate. Multiple legs are provided on the bottom end of the support plate away from the test base. A vibration mechanism is connected to the support plate. A horizontally positioned base plate is fixedly connected to one end of each leg away from the support plate. The vibration mechanism includes a vibrator fixedly connected to the side of the support plate away from the test base. A fixing component to prevent the test base from moving is connected between the support plate and the test base. Each leg is a cylinder, and the cylinder body of the leg is fixed to the base plate. A vertical spring is fixedly connected to the top of the piston rod of the support leg. The end of the spring away from the support leg is fixed to the side of the support plate away from the test base. A shock-absorbing layer is connected to the side of the base plate away from the support leg. The fixing assembly includes at least one insert plate fixedly connected to the top wall of the support plate away from the support leg and a slot opened on the bottom wall of the test base near the support plate. The slot is adapted to the insert plate. The slot is opened in a ring shape along the circumference of the test base. The end of the insert plate away from the support plate is arc-shaped. Through the cooperation between the vibrator, spring, insert plate and annular slot, the performance of the motor in static and dynamic environments can be detected.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent can detect the performance of a motor in static and dynamic environments through the cooperation between a vibrator, a spring, a plug plate, and a ring slot. However, it cannot perform continuous vibration testing on the motor, cannot improve the detection accuracy by reducing external interference, and has low detection efficiency.

[0014] Furthermore, the unlocking component includes: a first cylinder, a fourth bracket, and a guide wheel. The first cylinder is fixedly mounted on the left side wall of the double-speed chain conveyor via the bracket. The fourth bracket is fixedly mounted on the output end of the first cylinder. The guide wheel is rotatably connected to the end of the fourth bracket away from the first cylinder via a rotating shaft.

[0019] Furthermore, the lifting mechanism, the first linear module, the second linear module, the pneumatic gripper, the first motor, the camera, the light source assembly, the first cylinder, the vibration table, the second cylinder, the third linear module, the electric three-jaw chuck, the torque sensor, the third cylinder, and the noise tester are all controlled by an external controller.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. The motor is continuously conveyed by the double-speed chain conveyor. When the motor is conveyed to the preset position, the lifting mechanism is activated to lift the locking device. The first cylinder of the unlocking component extends and drives the fourth bracket and guide wheel to move to the right. The fourth bracket and guide wheel move to the right so that the guide wheel is close to the left side wall of the inclined plate of the locking device. The left side wall of the inclined plate is an inclined surface. The guide wheel moves to the right so that the inclined plate moves backward. The backward movement of the inclined plate drives the sliding rod to move backward. The backward movement of the sliding rod drives the first sliding plate to move backward. The first sliding plate leaves the motor under test, so that the motor under test is unlocked. This is beneficial for the rapid unlocking, locking and continuous conveying of the motor.

[0021] 2. The interface of the motor under test is identified by the identification component. The external controller, in conjunction with the left and right position of the interface of the motor under test identified by the identification component, controls the distance that the output end of the first linear module moves to the left, so that the wiring component moves directly above the interface of the motor under test. The output end of the second linear module moves downward, causing the wiring component to move downward. The vertical frame of the wiring component moves downward, causing the plug to move downward, so that the plug of the wiring component is inserted into the interface of the motor under test. The output shaft of the first motor holding component rotates, causing the lead screw to rotate. The rotation of the lead screw causes the abutment block to move away from the plug, so that the abutment block leaves the plug, which is conducive to the quick wiring of the motor.

[0022] 3. By isolating the gap between the two sliding frames with sponge strips, the sealing performance is improved. At the same time, it is beneficial for the wires on the upper side of the plug to slide between the sponge strips. The operating noise of the motor under test is tested by the noise tester of the noise test component. The motor's vibration resistance performance is detected by torque test and noise test. The separation setting of the frame and the first support without contact reduces noise interference and avoids the influence of equipment resonance on noise detection. This is beneficial for detecting the motor's vibration resistance performance and improves detection efficiency and accuracy. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] The present invention will be further described below with reference to embodiments.

[0041] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0042] Example 1: In some examples, please refer to Figures 1-13A motor vibration resistance testing device includes a frame 1. A double-speed chain conveyor 2 is arranged on the left side of the frame 1. Multiple pallets 3 are arranged on the upper side of the double-speed chain conveyor 2, and locking devices 11 are installed on the pallets 3. A lifting mechanism 5 is installed on the middle side of the double-speed chain conveyor 2. A first opening 6 is opened on the middle side of the frame 1. A first bracket 7 is arranged in the first opening 6. Sound-absorbing cotton 8 is fixedly installed on the four inner side walls of the first opening 6. The four outer side walls of the first bracket 7 do not contact the sound-absorbing cotton 8. A testing device 9 is installed on the upper side of the first bracket 7. A material conveying device 10 is installed on the upper side of the frame 1, located above the testing device 9. The device 10 includes: a first linear module 101, a second linear module 102, a pneumatic gripper 103, a wire insertion assembly, and an identification assembly. The first linear module 101 is fixedly mounted on the upper side of the frame 1 by a bracket. The second linear module 102 is fixedly mounted on the output end of the first linear module 101. The output end of the first linear module 101 moves left and right in the horizontal direction, and the output end of the second linear module 102 moves up and down in the vertical direction. The pneumatic gripper 103 is fixedly mounted on the left side of the output end of the second linear module 102. The wire insertion assembly is mounted on the right side of the output end of the second linear module 102. The identification assembly is mounted on the front side of the wire insertion assembly. The lifting mechanism 5 can be configured as a ball screw lifting mechanism.

[0043] The motor to be tested is placed on the locking device 11 of the pallet 3 of the double-speed chain conveyor 2. The motor to be tested is locked by the locking device 11 and continuously conveyed by the double-speed chain conveyor 2. When it reaches the preset position, the lifting mechanism 5 is activated to lift the locking device 11. The output end of the second linear module 102 of the feeding device 10 moves downward, driving the pneumatic gripper 103 to move downward. The pneumatic gripper 103 moves downward and approaches the motor to be tested. The locking device 11 releases the motor to be tested, and the pneumatic gripper 103 starts to clamp the motor to be tested. The output end of the second linear module 102 moves upward to the preset position. Then, the output end of the first linear module 101 moves to the right, driving the second linear module 102, the pneumatic gripper 103 and the motor to be tested to move to the right, moving to directly above the testing device 9. The output end of the second linear module 102 moves downward, driving the pneumatic gripper 103 and the motor to be tested to move downward. The pneumatic gripper 103 releases the motor to be tested, thus completing the conveying of the motor to be tested, which is beneficial for continuous conveying and feeding of motors.

[0044] The identification component identifies the interface of the motor under test. The external controller, in conjunction with the left and right positions of the interface of the motor under test identified by the identification component, controls the distance by which the output end of the first linear module 101 moves to the left, so that the wiring component moves to directly above the interface of the motor under test.

[0045] The cable assembly includes an extension bracket 104, a vertical frame 105, a plug 106, and a clamping assembly. The extension bracket 104 is fixedly installed on the right side of the output end of the second linear module 102. The vertical frame 105 is fixedly installed on the lower side of the extension bracket 104. A second opening 4 is provided in the middle of the vertical frame 105. A slot is provided on the lower side of the vertical frame 105. The second opening 4 and the plug 106 have the same shape. The plug 106 is slidably connected in the vertical frame 105. The clamping assembly is installed on the lower side of the vertical frame 105 and is located on the side with the slot.

[0046] After the wiring assembly is moved directly above the interface of the motor under test, the output end of the second linear module 102 moves downward, causing the wiring assembly to move downward. The vertical frame 105 of the wiring assembly moves downward, causing the plug 106 to move downward, so that the plug 106 of the wiring assembly is inserted into the interface of the motor under test. This facilitates the subsequent start-up of the motor under test and the quick wiring of the motor.

[0047] After the test is completed, the clamping assembly moves the plug 106 away from the interface of the motor under test.

[0048] The clamping component of the plug assembly clamps the plug 106. The output end of the second linear module 102 moves upward, causing the clamping component to move upward, and the plug 106 is pulled out from the interface of the motor to be tested.

[0049] Example 2: In some embodiments, such as Figures 1-13 As shown, in a preferred embodiment of the present invention, the clamping assembly includes: a second bracket 107, a first motor 108, a lead screw 109, an abutment block 1010, and a fixing rod 1011. The second bracket 107 is fixedly installed on the lower right side of the vertical frame 105, the first motor 108 is fixedly installed on the right side of the second bracket 107, the lead screw 109 is fixedly installed on the output shaft of the first motor 108 via a coupling, the abutment block 1010 is disposed in a slot, the right side of the abutment block 1010 is threadedly connected to the left end of the lead screw 109 away from the first motor 108, and a plurality of fixing rods 1011 are fixedly installed on the right side of the abutment block 1010, the end of the fixing rod 1011 away from the abutment block 1010 is slidably connected to the second bracket 107.

[0050] After the test motor is completed, the output shaft of the first motor 108 of the clamping assembly rotates, driving the lead screw 109 to rotate. The rotation of the lead screw 109 drives the abutment block 1010 to move towards the plug 106. The abutment block 1010 abuts the plug 106 against the inner wall of the vertical frame 105, so that the plug 106 is fixed on the vertical frame 105. At this time, the output end of the second linear module 102 moves upward, driving the abutment block 1010 of the clamping assembly of the plug assembly and the vertical frame 105 of the plug assembly to move upward, pulling the plug 106 out of the interface of the motor to be tested.

[0051] Next, the output end of the first linear module 101 moves to the right by a preset distance, causing the pneumatic gripper 103 at the output end of the second linear module 102 to move to the right by a preset distance. The output end of the second linear module 102 moves downward, causing the pneumatic gripper 103 to move downward, clamping the tested motor. The output end of the second linear module 102 moves upward, causing the pneumatic gripper 103 and the tested motor to move upward. The output end of the first linear module 101 moves to the left, causing the second linear module 102, the pneumatic gripper 103, and the tested motor to move to the left, stopping at a preset position. The output end of the second linear module 102 moves downward, causing the pneumatic gripper 103 and the tested motor to move downward, conveying the tested motor to the locking device 11 on the pallet 3 lifted by the lifting mechanism 5. The lifting mechanism 5 descends, lowering the pallet 3 and the locking device 11 to the initial position, and the tested motor continues to be conveyed by the double-speed chain conveyor 2.

[0052] The recognition component includes a camera 1012 and a light source assembly 1013. The camera 1012 is fixedly mounted on the front side wall of the vertical frame 105 by a bracket. The light source assembly 1013 is fixedly mounted on the camera 1012 and is used to provide illumination for the camera 1012 to recognize objects. The camera 1012 is a Basler ACA2500-14GM model camera, and the light source assembly 1013 is an OPT-RI27270-B model light source manufactured by opt.

[0053] Light is provided by the light source component 1013, identified by the camera 1012, and the information transmitted by the camera 1012 is processed by the external controller to locate the interface of the motor under test.

[0054] Example 3: In some embodiments, such as Figures 1-13 As shown, in a preferred embodiment of the present invention, the locking device 11 includes: a first fixing plate 111, a third bracket 112, a sliding rod 113, a first sliding plate 114, an inclined plate 115, a spring 116, and an unlocking assembly. The first fixing plate 111 is fixedly installed on the front side of the support plate 3, the third bracket 112 is fixedly installed on the rear side of the support plate 3, a plurality of sliding rods 113 are slidably connected to the third bracket 112, the first sliding plate 114 is fixedly installed on the front side of the sliding rod 113, the inclined plate 115 is fixedly installed on the rear side of the sliding rod 113, the spring 116 is disposed on the sliding rod 113, one end of the spring 116 is in close contact with the rear side of the first sliding plate 114, and the other end of the spring 116 is in close contact with the third bracket 112. The left side wall of the inclined plate 115 is an inclined surface, and the unlocking assembly is installed on the left side of the double-speed chain conveyor 2.

[0055] The motor to be tested is placed between the first fixed plate 111 and the first sliding plate 114 of the locking device 11 by manual operation or external robotic arm. At this time, the spring 116 generates elastic deformation, so that the motor to be tested is fixed between the first fixed plate 111 and the first sliding plate 114.

[0056] The lifting mechanism 5 is activated to lift the locking device 11, and the motor to be tested is unlocked through the unlocking component of the locking device 11.

[0057] The unlocking assembly includes a first cylinder 117, a fourth bracket 118, and a guide wheel 119. The first cylinder 117 is fixedly mounted on the left side wall of the double-speed chain conveyor 2 via the bracket. The fourth bracket 118 is fixedly mounted on the output end of the first cylinder 117. The guide wheel 119 is rotatably connected to the end of the fourth bracket 118 away from the first cylinder 117 via a rotating shaft. The guide wheel 119 is in close contact with the left side wall of the inclined plate 115.

[0058] The extension of the first cylinder 117 of the unlocking component causes the fourth bracket 118 and guide wheel 119 to move to the right. The rightward movement of the fourth bracket 118 and guide wheel 119 causes the guide wheel 119 to press against the left side wall of the inclined plate 115 of the locking device 11. The left side wall of the inclined plate 115 is an inclined surface. The rightward movement of the guide wheel 119 causes the inclined plate 115 to move backward. The backward movement of the inclined plate 115 causes the sliding rod 113 to move backward. The backward movement of the sliding rod 113 causes the first sliding plate 114 to move backward. The first sliding plate 114 moves away from the motor under test, thereby unlocking the motor under test.

[0059] The testing device 9 includes: a vibration table 91, a support plate 92, a second fixed plate 93, a second cylinder 94, a second sliding plate 95, and a synchronous rotation assembly. The vibration table 91 is fixedly installed on the upper side of the first bracket 7, the support plate 92 is fixedly installed on the upper side of the vibration table 91, the second fixed plate 93 is fixedly installed on the rear side of the support plate 92, the second cylinder 94 is fixedly installed on the front side of the support plate 92, the second sliding plate 95 is fixedly installed on the output end of the second cylinder 94, and the synchronous rotation assembly is installed on the right side of the support plate 92.

[0060] The motor under test is placed on the support plate 92 of the testing device 9 via the feeding device 10. The output end of the second cylinder 94 extends, driving the second sliding plate 95 to move towards the motor under test, so that the motor under test is quickly clamped between the second fixed plate 93 and the second sliding plate 95. The output shaft of the motor under test is clamped by the synchronous rotation assembly to facilitate subsequent testing. The vibration table 91 vibrates, causing the support plate 92 to vibrate. The vibration of the support plate 92 causes the second fixed plate 93, the second sliding plate 95, and the motor under test to vibrate. After the plug 106 is plugged into the interface of the motor under test, the power is turned on by the external controller to start the motor under test.

[0061] The synchronous rotation assembly includes: a third linear module 96, a fifth bracket 97, an electric three-jaw chuck 98, and a torque sensor 99. The third linear module 96 is fixedly installed on the right side of the support plate 92. The fifth bracket 97 is fixedly installed on the left side of the output end of the third linear module 96. The electric three-jaw chuck 98 is rotatably connected to the fifth bracket 97. The fixed end of the torque sensor 99 is fixedly installed on the fifth bracket 97, and the output end of the torque sensor 99 is fixedly installed on the right side of the electric three-jaw chuck 98.

[0062] The output end of the third linear module 96 of the synchronous rotating component moves to the left and stops at a preset position. The electric three-jaw chuck 98 starts to clamp the output shaft of the motor under test. The motor under test starts, causing the electric three-jaw chuck 98 to rotate. The torque sensor 99 records the torque change when the motor under test is running. The vibration table 91 of the test device 9 vibrates to detect the vibration resistance of the motor under test.

[0063] An anti-interference device 12 is installed on the upper side of the frame 1. The anti-interference device 12 includes: an irregularly shaped frame 121, a sliding frame 122, a third cylinder 123, and a noise testing component. Two irregularly shaped frames 121 are symmetrically fixedly installed on the frame 1 along the central axis of the frame 1. A sliding frame 122 is slidably connected to each irregularly shaped frame 121. A third cylinder 123 is fixedly installed on both the left and right sides of the frame 1. The right side wall of the sliding frame 122 on the front side of the frame 1 is fixedly connected to the output end of the third cylinder 123 on the right side of the frame 1. The left side wall of the sliding frame 122 on the rear side of the frame 1 is fixedly connected to the output end of the third cylinder 123 on the left side of the frame 1. The noise testing component is installed inside the sliding frame 122.

[0064] The output end of the third cylinder 123 of the anti-interference device 12 shortens, causing the sliding frame 122 to move towards each other. The two sliding frames 122 close, thus sealing the test device 9 to avoid external noise interference. The operating noise of the motor under test is then tested through the noise test component.

[0065] The noise testing assembly includes a noise tester 124 and a sponge strip 125. Multiple noise testers 124 are fixedly installed on the inner wall of the sliding frame 122. The sponge strip 125 is fixedly installed at one end of the sliding frame 122 near the central axis of the frame 1, used to isolate the gap between two sliding frames 122, improving sealing. It also allows the wires on the upper side of the plug 106 to slide between the sponge strips 125. The noise tester 124 of the noise testing assembly tests the operating noise of the motor under test. Through torque and noise testing, the motor's vibration resistance is detected. The non-contact arrangement of the frame 1 and the first support 7 reduces the impact of the first support 7 on the frame 1, preventing interference from the anti-interference device 12 on the frame 1, improving the detection accuracy of the anti-interference device 12, reducing noise interference, and avoiding equipment resonance and other factors affecting noise detection. This facilitates the detection of the motor's vibration resistance, improving detection efficiency and accuracy.
