[0016] Compared with existing technologies, a mechanical testing system for automotive motors that adopts the above-mentioned technical solution has the following beneficial effects: 1. In this invention, by setting up a multi-point detection component, the drive source, drive gear and rotating gear ring drive the rotating ring to drive multiple measuring instruments to rotate and measure around the motor under test. Combined with the electric push rod to flexibly adjust the angle of the measuring instruments, the two can simultaneously acquire multi-dimensional data, which saves time and improves measurement efficiency compared to single-point multiple measurements. It can also reduce detection blind spots, realize multi-point and multi-angle collaborative measurement of the outer periphery of the motor, and display and store the measurement data in real time. This allows for cross-validation of the data, significantly reduces the error risk of a single detection point, and comprehensively improves the accuracy, efficiency and reliability of the detection.

[0017] 2. In this invention, the lifting plate, adsorption plate, and supporting balls are raised and lowered in tandem by a movable cylinder. After the detection platform moves to the designated position, it is automatically lifted and adsorbed and fixed. The relative movement of the piston cylinder and piston rod creates negative pressure in the adsorption plate, which effectively enhances the stability of the detection platform during the measurement process and ensures the accuracy of the detection data. In conjunction with the first conveying mechanism, it can realize continuous measurement of the motor to be tested, improving measurement efficiency. After the test is completed, for qualified products, the adsorption can be automatically released and reset, allowing the detection platform to fall smoothly back to the first conveying mechanism, realizing continuous automated flow. For unqualified products, the fixed motor drives the rotating disk and adsorption structure to rotate the detection platform 90 degrees and align it with the height of the second conveying mechanism. After the adsorption is released, it is automatically transferred by the defective product conveying component, realizing efficient sorting and diversion of qualified and defective products.

[0018] 3. In this invention, through the linkage design of the adsorption plate rotation with the piston cylinder, sealing pipe, connecting frame, sliding rod, and trigger rod, the lifting platform is automatically triggered to rise after rotation to the correct position. This causes the inclined surface of the trigger block to push the trigger rod, moving the sealing plug, thereby opening the sealing pipe and relieving the negative pressure on the adsorption plate. This achieves rapid and automatic release between the detection platform and the adsorption plate. Subsequently, the lifting platform drives the transfer device to contact the detection platform, and the output motor drives the conveyor belt to smoothly transfer the defective motor to the second conveying mechanism. The entire process is continuous and automatic, requiring no manual intervention. This significantly improves the efficiency and accuracy of defective motor classification and transfer, reduces equipment complexity and operating costs, and is suitable for the automated sorting needs of motor testing production lines.

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.

[0022] Please see Figures 1-4 and Figure 10 The present invention provides a technical solution: A mechanical testing system for automotive motors includes a first conveying mechanism 1 and a second conveying mechanism 4. A data recording device 5 is connected to one side of the second conveying mechanism 4. A supporting base plate 6 is connected to the bottom of the first conveying mechanism 1. The first conveying mechanism 1 and the second conveying mechanism 4 are arranged in a T-shape. Both the first conveying mechanism 1 and the second conveying mechanism 4 consist of a frame, conveying rollers, sprockets, chains, and an output motor. Limiting annular grooves are formed on the outer surfaces of both ends of the conveying rollers. Two symmetrically arranged limiting slide rods 9 are connected to the bottom of the testing platform 2. The limiting slide rods 9 are slidably connected within the limiting annular grooves. The system also includes: Multiple testing platforms 2 are set on the first conveying mechanism 1 and the second conveying mechanism 4 for placing the motor to be tested; A multi-point detection component 3 is disposed on one side of the first conveying mechanism 1. The multi-point detection component 3 includes a fixed ring 310 that can be raised and lowered in the vertical direction. A lifting mechanism is disposed on the outer periphery of the fixed ring 310. The lifting mechanism is disposed on one side of the first conveying mechanism 1. A rotating toothed ring 304 is rotatably connected to the top of the fixed ring 310. A rotating ring 313 is connected to the bottom of the rotating toothed ring 304. The rotating ring 313 is rotatably connected to the fixed ring 310. Multiple angle-adjustable measuring instruments 315 are disposed inside the rotating ring 313. The multi-point detection component 3 also includes: Multiple electric push rods 314 are arranged in a circular array on the top of the rotating gear ring 304. One end of each electric push rod 314 is hinged to the top of the rotating gear ring 304 through a hinge seat, and the output end of each electric push rod 314 is hinged to one end of the measuring instrument 315. The fixed bases are arranged in a circular array inside the rotating ring 313, and the measuring instrument 315 is hinged to the fixed bases; The drive source 312 is fixedly installed at the bottom of the lead screw seat 305; The drive gear 311 meshes with the rotating gear ring 304. One end of the output shaft of the drive source 312 is connected to a rotating shaft, and one end of the rotating shaft extends to the other side of the lead screw seat 305 and is connected to the bottom of the drive gear 311. The lifting mechanism includes: Assembly plate 308 is connected to one side of the first conveying mechanism 1; A fixing slot 307 is connected to the top of the assembly plate 308, and a top plate 301 is connected to the top of the fixing slot 307; The adjusting screw 306 is rotatably connected inside the fixed slot seat 307. The outer surface of the adjusting screw 306 is connected to the screw seat 305, and the screw seat 305 is connected to one side of the fixed ring 310. Two fixed slide rods 303 are symmetrically connected to the top plate 301 on the side away from the fixed groove seat 307. The other end of the fixed slide rod 303 is connected to the top of the first conveying mechanism 1. A sliding sleeve 302 is slidably connected to the outer surface of the fixed slide rod 303. One side of the sliding sleeve 302 is connected to one side of the fixed ring 310. The drive motor 309 is fixedly mounted on the bottom of the assembly plate 308 via a mounting plate. One end of the adjusting screw 306 extends to the other side of the assembly plate 308 and is connected to one end of the output shaft of the drive motor 309.

[0023] The specific usage method and working principle are as follows: The staff places the motor to be tested on the first conveying mechanism 1 through the testing platform 2. When the testing platform 2 conveys the motor to be tested to the point directly below the multi-point testing platform 2, the lifting conversion component 8 can lift the testing platform 2 upward and separate it from the first conveying mechanism 1 to ensure the stability of the motor to be tested during measurement. Subsequently, the drive motor 309 starts, driving the adjusting screw 306 to rotate within the fixed slot 307. The adjusting screw 306 then drives the screw seat 305 to move within the fixed slot 307. The screw seat 305, in conjunction with the sliding sleeve 302 and the fixed slide rod 303, drives the fixed ring 310 to descend vertically. The cooperation between the sliding sleeve 302 and the fixed slide rod 303 ensures the stability of the fixed ring 310's rise and fall. The fixed ring 310 drives the rotating ring 313 to move, and multiple measuring instruments 315 within the fixed ring 310 measure the outer periphery of the motor under test. During this process... In the process, the drive source 312 drives the drive gear 311 to rotate, the drive gear 311 drives the rotating gear ring 304 to rotate, the rotating gear ring 304 drives the rotating ring 313 to rotate, and the rotating ring 313 drives the measuring instrument 315 to rotate around the motor under test for measurement. At the same time, according to the actual measurement requirements, multiple measuring instruments 315 can adjust the measurement angle under the drive of the electric push rod 314, and display the measurement data and store it in the data recording device 5 to avoid data omission, realize multi-point collaborative measurement, and cross-verify data to reduce the error risk of a single detection point. If the measured data is within the error range, the lifting conversion component 8 is reset, so that the detection platform 2 returns to its original position and continues to move to the other end with the first conveying mechanism 1; if the measured data exceeds the error range, the motor to be tested is a defective product. Then, the defective product conveying component 7, together with the lifting conversion component 8, conveys the defective product to the second conveying mechanism 4. The lifting conversion component 8, together with the first conveying mechanism 1, can realize continuous measurement of the motor to be tested. It should be noted that when placing the testing platform 2, the limiting slide bar 9 should be aligned with the limiting ring groove on the conveying roller. The limiting ring groove limits the limiting slide bar 9 to ensure the stable conveying of the testing platform 2 on the first conveying mechanism 1 and prevent the testing platform 2 from deviating. The bottom of the testing platform 2 is a smooth, flat and pore-free plane. The drive source 312 is a self-locking motor with controllable rotation angle. The data recording device 5 is a TP1000 paperless recorder, and the measuring instrument 315 is a Keyence IM-7000 image measuring instrument.

[0024] Please see Figures 5-9 The enhancement conversion component 8 includes: The lifting plate 803 is disposed between the supporting base plate 6 and the first conveying mechanism 1; A piston cylinder 811 is provided with an outer ring 808 connected to its outer surface. An annular groove is provided on the outer periphery of the outer ring 808. The outer ring 808 is rotatably connected to the lifting plate 803 through the annular groove. A piston rod 809 is sealed and slidably disposed inside the piston cylinder 811. The adsorption plate 801 is connected to the top of the piston cylinder 811 and is used to limit the adsorption of the detection platform 2. Two supporting balls 802, each with a mounting base at its bottom, and the two mounting bases are symmetrically connected to the top of the lifting plate 803. The base block 805 is connected to the top of the supporting base plate 6, and the base block 805 has an internal cavity. Rotating disk 806 is rotatably connected to the top of base block 805; Two sealed pipes 810 are connected to both sides of the piston cylinder 811, and a defective product conveying assembly 7 is provided on one side of each of the two sealed pipes 810. Two telescopic rods 812 are symmetrically connected to both sides of the rotating disk 806, and the telescopic rods 812 are connected to the sealing pipe 810; Two movable cylinders 804 are symmetrically connected to the top of the base block 805, and the output end of the movable cylinders 804 is connected to the bottom of the lifting plate 803. A fixed motor 807 is fixedly installed inside the cavity of the base block 805. One end of the output shaft of the fixed motor 807 extends to the outside of the cavity and is connected to the bottom of the rotating disk 806.

[0025] The specific usage method and working principle are as follows: When the detection platform 2 moves the motor to be tested to directly below the multi-point detection component 3, the two movable cylinders 804 drive the same lifting plate 803 to move upward. The lifting plate 803 drives the adsorption plate 801 and the supporting ball 802 to move upward. The lifting plate 803, the adsorption plate 801 and the supporting ball 802 pass through the gap between the two conveying rollers. The adsorption plate 801 and the supporting ball 802 are both in contact with the bottom of the detection platform 2 and gradually raise the height of the detection platform 2. During this process, the lifting plate 803 drives the piston cylinder 811 to move upward through the outer ring 808, so that the piston cylinder 811 moves relative to the piston rod 809, thereby realizing the evacuation of air from the adsorption plate 801, so that a negative pressure is formed in the adsorption plate 801 and the bottom of the detection platform 2 is adsorbed and limited, ensuring the stability of the detection platform 2 during measurement. After the multi-point detection component 3 completes the measurement, if the motor to be tested is qualified, the movable cylinder 804 drives the lifting plate 803 to reset. At this time, the piston cylinder 811 is reset under the drive of the lifting plate 803. This is equivalent to the piston rod 809 cooperating with the piston cylinder 811 to inject air into the adsorption plate 801, so that the pressure inside and outside the adsorption plate 801 is consistent. The adsorption plate 801 releases the adsorption limit on the detection platform 2. Furthermore, as the supporting ball 802 and the adsorption plate 801 are reset, the height of the detection platform 2 decreases. The detection platform 2 re-contacts the first conveying mechanism 1 and continues to move under the drive of the first conveying mechanism 1. If the motor to be tested is unqualified, the fixed motor 807 is started, which drives the rotating disk 806 to rotate 90 degrees. The rotating disk 806 drives the two telescopic rods 812 to rotate. The two telescopic rods 812 drive the piston cylinder 811 to rotate through the sealed pipe 810. The piston cylinder 811 drives the testing platform 2 and the motor to be tested to rotate 90 degrees through the adsorption disk 801. At this time, the height of the testing platform 2 is flush with the height of the second conveying mechanism 4. Then, the defective product conveying component 7 is started, which releases the adsorption limit of the adsorption disk 801 on the testing platform 2, and conveys the testing platform 2 and the motor to be tested to the second conveying mechanism 4 through the defective product conveying component 7.

[0026] Please see Figures 5-9 The defective product conveying assembly 7 includes: The lifting platform 707 is located above the supporting base plate 6, and the lifting platform 707 is located on one side of the base block 805; A transfer device 701 is installed on the top of the lifting platform 707. The transfer device 701 consists of an assembly frame, a conveyor belt, and a conveyor motor. A sealing plug 702 is disposed at one end of the sealing tube 810, and the sealing plug 702 and the axis of the sealing tube 810 are located on the same axis, for sealing the sealing tube 810. A sliding rod 705 is connected to one side of the sealing plug 702. A connecting frame 704 is slidably connected to the outer surface of the sliding rod 705. The connecting frame 704 is connected to the bottom of the outer ring 808. A return spring 703 is sleeved on the outer surface of the sliding rod 705. The two ends of the return spring 703 are respectively connected to one side of the sealing plug 702 and one side of the connecting frame 704. The trigger rod 706 is connected to the end of the sliding rod 705 away from the sealing plug 702; Two trigger blocks 708 are symmetrically connected to the side of the lifting platform 707 near the base platform. Each trigger block 708 is composed of a straight block and an inclined block and is used to drive the trigger rod 706 to move. Two movable push rods 709 are symmetrically connected to the top of the supporting base plate 6, and the output end of the movable push rods 709 is connected to the bottom of the lifting platform 707.

[0027] The specific usage method and working principle are as follows: When defective motors need to be sorted and transferred, the adsorption plate 801 rotates 90 degrees under the drive of the fixed motor 807, and the detection platform 2 and the motor to be detected have been correctly aligned. During this process, the piston cylinder 811 drives the sealing pipe 810 and the connecting frame 704 to rotate 90 degrees. The connecting frame 704 drives the trigger rod 706 to rotate 90 degrees through the sliding rod 705. At this time, the trigger block 708 is located directly below the trigger rod 706 on the same side. Then, the movable push rod 709 drives the lifting platform 707 to move upward. The lifting platform 707 drives the two trigger blocks 708 to move upward. The inclined block part of the trigger block 708 gradually contacts the trigger rod 706, causing the trigger rod to... 706 gradually moves towards the straight block, and the trigger block 708 gradually drives the trigger rod 706 to move to one side. The trigger rod 706 drives the sliding rod 705 to move, and the sliding rod 705 drives the sealing plug 702 to move to one side, thus opening the port of the sealing pipe 810. This allows gas to enter the piston cylinder 811, thereby relieving the negative pressure state of the adsorption plate 801 and preventing the adsorption plate 801 from limiting the adsorption of the detection platform 2. After that, the lifting platform 707 drives the transfer device 701 to contact the bottom of the monitoring platform. Then, the output motor of the transfer device 701 drives the conveyor belt to run. The conveyor belt drives the detection platform 2 and the defective motor to move onto the second conveying mechanism 4, completing the classification and recycling of the defective motor.

[0028] It should be noted that the return spring 703 is a spring with strong elasticity, which can ensure the sealing effect of the sealing plug 702 on the sealing tube 810.
