Description

Technical Field

[0001] The present invention relates to the technical field of motor detection, and specifically to a device for detecting the seismic performance of a motor. Background Art

[0002] The detection of the seismic performance of a motor is an important means to evaluate whether the motor can operate normally and maintain structural integrity under vibration environments such as earthquakes, to evaluate the structural reliability, and to detect the strength and stability of the mechanical structure of the motor under vibration conditions, so as to determine whether it can withstand the expected seismic loads and prevent situations such as the rupture of the motor housing, the loosening or damage of internal parts. Usually, a vibration table is 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 the predetermined vibration conditions. During the test, instruments such as sensors are used to measure the performance of the motor in different vibration states.

[0003] The Chinese patent with the publication number CN212082760U proposes a device for detecting the seismic performance of a motor, which includes a horizontally arranged support plate and at least one test base installed on the top wall of the support plate. Multiple support feet are provided at the bottom end of the support plate facing away from the test base. A vibration mechanism is connected to the support plate. One end of the support foot facing away from the support plate is fixedly connected to a horizontally arranged bottom plate. The vibration mechanism includes a vibrator fixedly connected to the side of the support plate facing away from the test base. A fixing component for preventing the test base from moving is connected between the support plate and the test base. The support foot is a cylinder, the cylinder body of the support foot is fixed to the bottom plate, the top end of the piston rod of the support foot is fixedly connected to a vertical spring, and one end of the spring facing away from the support foot is fixed to the side of the support plate facing away from the test base. A shock-absorbing layer is connected to the side of the bottom plate facing away from the support foot. The fixing component includes at least one insertion plate fixedly connected to the top wall of the support plate facing away from the support foot and a slot opened on the bottom wall of the test base close to the support plate. The slot is adapted to the insertion plate. The slot is arranged in a ring shape along the circumferential direction of the test base. One end of the insertion plate facing away from the support plate is arc-shaped. Through the cooperation between the vibrator, the spring, the insertion plate, and the 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: This patent can detect the performance of the motor in static and dynamic environments through the cooperation between the vibrator, the spring, the insertion plate, and the annular slot. However, it cannot perform continuous anti-vibration detection on the motor, cannot improve the detection accuracy by reducing external interference, and has a low detection efficiency.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The motor is continuously conveyed by the double-speed chain conveyor. When it is conveyed to the preset position, the lifting mechanism is activated to lift the locking device. The first cylinder of the unlocking component extends to drive the fourth bracket and the guide wheel to move to the right. The rightward movement of the fourth bracket and the guide wheel makes the guide wheel closely adhere 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 rightward movement of the guide wheel makes the inclined plate move 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 moves away from the motor to be tested, so that the motor to be tested is unlocked, which is conducive to the rapid unlocking, locking, and continuous feeding of the motor. 2. The interface of the motor to be tested is identified by the identification component. The external controller combines the left and right positions of the interface of the motor to be tested identified by the identification component to control the distance that the output end of the first linear module moves to the left, so that the wire inserting component moves directly above the interface of the motor to be tested. The output end of the second linear module moves downward to drive the wire inserting component to move downward. The downward movement of the vertical frame of the wire inserting component drives the plug to move downward, so that the plug of the wire inserting component is inserted into the interface of the motor to be tested. The output shaft of the first motor of the clamping component rotates to drive the lead screw to rotate. The rotation of the lead screw drives the abutting block to move away from the plug, so that the abutting block moves away from the plug, which is conducive to the rapid wiring of the motor. 3. Isolate the gap between the two sliding frames through a sponge strip to improve the sealing performance. At the same time, it is beneficial for the wire on the upper side of the plug to slide between the sponge strips. Use the noise tester of the noise test component to test the running noise of the motor to be tested. Through torque testing and noise testing, the vibration resistance performance of the motor is detected. Through the separated setting where the frame and the first bracket do not contact, the noise interference is reduced, and the influence of equipment resonance on noise detection is avoided, which is beneficial for detecting the vibration resistance performance of the motor and improving the detection efficiency and detection accuracy.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] The "left", "right", "front", "rear", "upper", and "lower" mentioned in the following description are oriented in the perspective direction of the front view.

[0025] Embodiment 1: In some embodiments, please refer to Figures 1 - 13, a device for detecting the seismic performance of a motor, including a frame 1. A speed chain conveyor 2 is arranged on the left side of the frame 1. A plurality of pallets 3 are arranged on the upper side of the speed chain conveyor 2. A locking device 11 is installed on the pallet 3. A lifting mechanism 5 is installed in the middle of the speed chain conveyor 2. A first opening 6 is formed in the middle of the frame 1. A first support 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 in the front, back, left and right directions. The four outer side walls of the first support 7 do not contact the sound-absorbing cotton 8. A testing device 9 is installed on the upper side of the first support 7. A feeding device 10 is installed on the upper side of the frame 1. The feeding device 10 is located above the testing device 9. The feeding device 10 includes: a first linear module 101, a second linear module 102, a pneumatic gripper 103, a wiring assembly and an identification assembly. The first linear module 101 is fixedly installed on the upper side of the frame 1 through a bracket. The second linear module 102 is fixedly installed at 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. The output end of the second linear module 102 moves up and down in the vertical direction. The pneumatic gripper 103 is fixedly installed on the left side of the output end of the second linear module 102. The wiring assembly is installed on the right side of the output end of the second linear module 102. The identification assembly is installed on the front side of the wiring assembly. The lifting mechanism 5 can be set as a ball screw lifting mechanism.

[0026] Place the motor to be tested on the locking device 11 of the pallet 3 of the speed chain conveyor 2. Lock the motor to be tested through the locking device 11. Continuously convey it through the speed chain conveyor 2. When it is conveyed to the preset position, the lifting mechanism 5 starts to lift the locking device 11. The output end of the second linear module 102 of the feeding device 10 moves downward to drive the pneumatic gripper 103 to move downward. The pneumatic gripper 103 moves downward to approach the motor to be tested. The locking device 11 releases the motor to be tested. 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 to drive the second linear module 102, the pneumatic gripper 103 and the motor to be tested to move to the right. Move to directly above the testing device 9. The output end of the second linear module 102 moves downward to drive the pneumatic gripper 103 and the motor to be tested to move downward. The pneumatic gripper 103 releases the motor to be tested, which can complete the feeding of the motor to be tested, facilitating the continuous feeding of the motor.

[0027] Identify the interface of the motor to be tested through the identification assembly. Combine the left and right positions of the interface of the motor to be tested identified by the identification assembly through an external controller to control the distance that the output end of the first linear module 101 moves to the left, so that the wiring assembly moves to directly above the interface of the motor to be tested.

[0028] The wire plugging 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 side of the vertical frame 105. A slot is opened 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 inside the vertical frame 105. The clamping assembly is installed on the lower side of the vertical frame 105 and is located on one side where the slot is provided.

[0029] After the wire plugging assembly moves to directly above the interface of the motor to be tested, the output end of the second linear module 102 moves downward to drive the wire plugging assembly to move downward. The downward movement of the vertical frame 105 of the wire plugging assembly drives the plug 106 to move downward, so that the plug 106 of the wire plugging assembly is inserted into the interface of the motor to be tested, which is beneficial for the subsequent startup of the motor to be tested and is beneficial for the quick wiring of the motor.

[0030] After the test is completed, the clamping assembly drives the plug 106 to leave the interface of the motor to be tested.

[0031] The clamping assembly of the wire plugging assembly clamps the plug 106, and the output end of the second linear module 102 moves upward to drive the clamping assembly to move upward, pulling out the plug 106 from the interface of the motor to be tested.

[0032] Embodiment 2: In some embodiments, as Figures 1 - 13 shown, as a preferred embodiment of the present invention, the clamping assembly includes: a second bracket 107, a first motor 108, a lead screw 109, a contact block 1010, and a fixed 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 through a coupling. The contact block 1010 is arranged in the slot. The right side of the contact block 1010 is threadedly connected to one end of the left side of the lead screw 109 far from the first motor 108.

The end of the fixed rod 1011 far from the contact block 1010 is slidably connected to the second bracket 107.

[0033] After the motor to be tested is tested, the output shaft of the first motor 108 of the clamping assembly rotates to drive the lead screw 109 to rotate. The rotation of the lead screw 109 drives the contact block 1010 to move towards the plug 106. The contact block 1010 presses the plug 106 against the inner side 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 to drive the contact block 1010 of the clamping assembly of the wire plugging assembly and the vertical frame 105 of the wire plugging assembly to move upward, pulling out the plug 106 from the interface of the motor to be tested.

[0034] Next, the output end of the first linear module 101 moves to the right by a preset distance, driving the pneumatic gripper 103 at the output end of the second linear module 102 to move to the right by a preset distance. Then, the output end of the second linear module 102 moves downward, driving the pneumatic gripper 103 to move downward, clamping the tested motor. Next, the output end of the second linear module 102 moves upward, driving the pneumatic gripper 103 and the tested motor to move upward. Then, the output end of the first linear module 101 moves to the left, driving the second linear module 102, the pneumatic gripper 103, and the tested motor to move to the left. They stop moving to the preset position. Then, the output end of the second linear module 102 moves downward, driving the pneumatic gripper 103 and the tested motor to move downward, and 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 is continuously conveyed through the double-speed chain conveyor 2.

[0035] The identification component includes: a camera 1012 and a light source component 1013. The camera 1012 is fixedly installed on the front side wall of the vertical frame 105 through a bracket. The light source component 1013 is fixedly installed on the camera 1012 and is used to provide illumination for the camera 1012 to identify. The camera 1012 is set as the ACA2500-14GM model camera 1012 produced by Basler Company, and the light source component 1013 is set as the OPT-RI27270-B model light source produced by opt Company.

[0036] The light source component 1013 provides light, the camera 1012 conducts identification, and the external controller processes the information transmitted by the camera 1012 to position the interface of the motor to be tested.

[0037] Embodiment 3: In some embodiments, as Figures 1 - 13 shown, as 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 component.

A plurality of the 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 arranged on the sliding rod 113. One end of the spring 116 is closely attached to the rear side of the first sliding plate 114, and the other end of the spring 116 is closely attached to the third bracket 112. The left side wall of the inclined plate 115 is an inclined surface, and the unlocking component is installed on the left side of the double-speed chain conveyor 2.

[0038] The motor to be tested is placed between the first fixed plate 111 and the first sliding plate 114 of the locking device 11 manually or by an external manipulator. At this time, the spring 116 undergoes elastic deformation, causing the motor to be tested to be fixed between the first fixed plate 111 and the first sliding plate 114.

[0039] The lifting mechanism 5 is activated to lift the locking device 11, and the unlocking component of the locking device 11 unlocks the motor to be tested.

The guide wheel 119 is rotatably connected to one end of the fourth bracket 118 away from the first cylinder 117 through a rotating shaft, and the guide wheel 119 is in close contact with the left side wall of the inclined plate 115.

[0041] When the first cylinder 117 of the unlocking component extends, it drives the fourth bracket 118 and the guide wheel 119 to move to the right. The movement of the fourth bracket 118 and the guide wheel 119 to the right causes the guide wheel 119 to be in close contact with 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 movement of the guide wheel 119 to the right causes the inclined plate 115 to move backward. The backward movement of the inclined plate 115 drives the sliding rod 113 to move backward, and the backward movement of the sliding rod 113 drives the first sliding plate 114 to move backward. The first sliding plate 114 moves away from the motor to be tested, causing the motor to be tested to be unlocked.

[0042] 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 component.

[0043] The motor to be tested is placed on the support plate 92 of the testing device 9 through the feeding device 10. The output end of the second cylinder 94 extends to drive the second sliding plate 95 to move towards the motor to be tested, causing the motor to be tested to be quickly clamped between the second fixed plate 93 and the second sliding plate 95. The output shaft of the motor to be tested is clamped through the synchronous rotation component, facilitating subsequent testing. The vibration of the vibration table 91 drives the vibration of the support plate 92, and the vibration of the support plate 92 drives the vibration of the second fixed plate 93, the second sliding plate 95, and the motor to be tested. After the interface of the motor to be tested is plugged with the plug 106, the power supply is turned on through the control of an external controller to start the motor to be tested.

[0044] 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.
