[0002] The servo drive motor is an advanced motor drive system that converts electrical energy into mechanical energy for precise control of rotation speed, position and torque. It usually consists of a motor body, a servo drive and a feedback device. The servo motor is a precision motor drive system that has been widely used in many industrial and automation fields due to its excellent control performance and reliability. It can provide high-precision motion control, fast response performance, good dynamic characteristics and high energy efficiency, and has strong environmental adaptability and reliability.

[0003] In the prior art, when collecting data on a servo motor, an external load is usually added to it to simulate its various working performances under different working environments, so as to adjust the servo motor so that it can work better in the corresponding scenario.

[0005] A Chinese patent with publication number CN118226255B discloses a motor detection device, including a counterweight assembly and a moving mechanism that pushes the motor to be detected to move toward the counterweight assembly and an elliptical counterweight plate. The clamping assembly is adjusted so that the clamping assembly clamps the two ends of the short axis of the elliptical counterweight plate, so that the center of gravity of the counterweight assembly deviates from the center of the transmission shaft, and then the eccentric load detection is achieved by controlling the operation of the motor to be detected.

[0031] Specifically, the workbench 11 can provide stable support for the slide rail 12, the slide rail 12 can provide sliding support for the slide plate 13, the slide plate 13 can provide fixed support for the motor 15 to be tested, and the telescopic rod 14 can provide a sliding driving force for the slide plate 13. When the telescopic rod 14 contracts, the output end of the telescopic rod 14 drives the slide plate 13 to move, and then the motor 15 to be tested is moved to a position close to or away from the coupling 23 through the slide plate 13, so as to facilitate the disassembly and assembly of the output end of the motor 15 to be tested and the coupling 23.

[0032] In this embodiment, a rotating mechanism 2 is provided on the top of the workbench 11, and the rotating mechanism 2 includes a positioning rod 25. The rotating mechanism 2 also includes two support plates 21, and the two support plates 21 are fixedly installed on the top of the workbench 11 by bolts. The interiors of the two support plates 21 are respectively installed with rotating shafts 22 passing through bearings, wherein a coupling 23 is fixedly installed at one end of one rotating shaft 22 away from the other rotating shaft 22, and a rotating plate 24 is fixedly installed at one end of the two rotating shafts 22 close to each other, and the positioning rod 25 is fixedly installed between the two rotating plates 24, and the positioning rod 25 is square, and a threaded hole is opened through the interior thereof.

[0033] Specifically, the support plate 21 can provide rotational support for the rotating shaft 22, and the rotating shaft 22 can provide stable support for the coupling 23 and the rotating plate 24. When the rotating shaft 22 is driven to rotate by the coupling 23, the rotating shaft 22 drives the rotating plate 24 and the adjusting rod 25 to rotate together, and the rotating shaft 22 is the center of rotation.

[0034] In this embodiment, the vibration mechanism 6 is assembled to provide torque support for the transposition assembly 5 through a support seat 61 arranged on the top of the workbench 11, and a pressure plate 68 arranged inside the support seat 61 provides vibration support for the transposition assembly 5; the support seat 61 is fixedly installed on the top of the workbench 11 by bolts, and the support seat 61 is rotatably mounted on the outer side of the rotating plate 24 away from the coupling 23 through a bearing, and a large circular groove 62 is opened on the side of the support seat 61 close to the coupling 23, and the large circular groove 62 is located on the outer side of the rotating disk 41 A small circular groove 63 is provided on the inner side of the large circular groove 62, and the small circular groove 63 is located on the outer side of the fixing ring 47. One end of two springs 64 is fixedly installed on the top of the support seat 61, and a push plate 65 is fixedly installed on the other end of the spring 64. An adjusting block 66 is rotatably installed inside the push plate 65 through a bearing. A screw 67 is threadedly installed on the inner side of the adjusting block 66. A pressure plate 68 is fixedly installed on one end of the screw 67 close to the support seat 61, and the pressure plate 68 passes through the top of the support seat 61 and contacts with the top of the fixing ring 47.

[0035] Specifically, the support seat 61 can provide stable support for the spring 64, the spring 64 can provide elastic support for the push plate 65, and the push plate 65 can provide rotational support for the adjusting block 66. When the adjusting block 66 rotates under the action of external force, the adjusting block 66 moves upward by utilizing the threaded action with the screw 67, so that the adjusting block 66 drives the pressure plate 68 to move upward, and the pressure plate 68 pulls the rope spring 64 upward, thereby increasing the pressure of the pressure plate 68 on the fixing ring 47, facilitating the adjustment of the vibration load.

[0036] In this embodiment, the detection mechanism 3 includes a supporting component 4 and a shifting component 5; the supporting component 4 includes a turntable 41, which is arranged on the outer side of the adjusting rod 25 to provide support for the shifting component 5; a movable hole 42 is opened through the inside of the turntable 41, and the movable hole 42 is located on the outer side of the adjusting rod 25, the inner side of the top wall of the movable hole 42 contacts the top of the adjusting rod 25, a plurality of receiving grooves 43 are opened on the outer side of the turntable 41, two square grooves 44 are opened inside the turntable 41, and the two square grooves 44 are symmetrically distributed with respect to the center of the turntable 41, side grooves 45 are opened on both sides of the square groove 44, and the side grooves 45 are communicated with the square grooves 44, a plurality of inclined holes 46 are opened through the inside of the turntable 41, and the inclined holes 46 connect the receiving grooves 43 and the side grooves 45, and a fixing ring 47 is fixedly installed on the side of the turntable 41 away from the coupling 23.

[0037] Specifically, the turntable 41 can provide a through-opening space for the movable hole 42, and the movable hole 42 can provide a through-opening space for the adjusting rod 25. When the adjusting rod 25 contacts the inner side of the top wall of the movable hole 42, the axis of the turntable 41 deviates from the axis of the rotating shaft 22, and is in an eccentric wheel state. When the adjusting rod 25 contacts the inner side of the bottom wall of the movable hole 42, the axis of the turntable 41 is coaxial with the axis of the rotating shaft 22, thereby facilitating the switching of the rotation state of the turntable 41. At the same time, the turntable 41 can provide an opening space for the storage slot 43, the square slot 44, the side slot 45, and the inclined hole 46, so as to provide a space for placing and moving the transposition component 5.

[0038] In this embodiment, the transposition component 5 is assembled to drive the turntable 41 arranged on the outside of the adjustment rod 25 to rotate, so that the turntable 41 drives the fixed ring 47 on one side to rotate, and the fixed ring 47 contacts with the end of the pressure plate 68 close to the turntable 41, so as to perform the vibration detection of the eccentric shaft of the motor 15 to be tested, and the threaded rod 51 inside the turntable 41 is rotated, so that the threaded rod 51 drives the turntable 41 to move by the threaded action with the adjustment rod 25, and at the same time, the inclined rod 56 on the inner side of the turntable 41 drives the roller 57 to contact with the inner side of the support seat 61, so as to perform the torque detection of the motor 15 to be tested, and the surface of the threaded rod 51 near the center position is provided with a coarse thread, and the coarse thread is threadedly connected with the threaded hole of the adjustment rod 25, and the surface of the threaded rod 51 is provided with another two fine threads, and the two fine threads are respectively located at the top and bottom of the coarse thread, and the thread directions of the two fine threads are opposite, and the thread pitch of the fine thread is smaller than the thread pitch of the coarse thread. The thread direction of the threaded rod 51 is the same as the thread direction of the fine thread on the top. The threaded rod 51 is installed on the top of the turntable 41 through multiple bearings. A swivel head 52 is fixedly installed on one end of the threaded rod 51 exposed to the outside of the turntable 41. A swivel rod 53 is slidably installed inside the swivel head 52, and the swivel head 52 and the swivel rod 53 are tightly matched. Square blocks 54 are respectively threadedly installed on the outside of the two fine threads of the threaded rod 51, and the square blocks 54 are located on the inner side of the square groove 44. Side wing plates 55 are respectively fixedly installed on both sides of the square block 54, and the side wing plates 55 are located on the inner side of the side groove 45. The inclined rod 56 is slidably mounted on the outside of the side wing plates 55, and the inclined rod 56 is located on the inner side of the inclined hole 46. The end of the inclined rod 56 away from the center of the turntable 41 is located on the inner side of the receiving groove 43. Two rollers 57 are respectively rotatably installed on both sides of the inclined rod 56, and the rollers 57 are located on the inner side of the receiving groove 43. The outer side of the rollers 57 is sleeved with rubber rings 58.

[0039] Specifically, the threaded rod 51 can provide a stable support for the rotating head 52, and the rotating head 52 can provide a penetrating space for the rotating rod 53. The rotating rod 53 on one side of the rotating head 52 is longer, and one end of the rotating rod 53 on the other side is close to the rotating head 52. When the rotating rod 53 is grasped and rotated, the rotating rod 53 drives the rotating head 52 and the threaded rod 51 to rotate with the rotating head 52 as the center. When the rotating rod 53 rotates 180°, the longer end of the rotating rod 53 is pressed toward the rotating head 52, and the rotating rod 53 slides along the inner side of the rotating head 52 to make the rotating rod 53 return to the initial state. Repeating the operation can make the threaded rod 51 rotate in one direction, and the threaded rod 51 can provide threaded action for the adjustment rod 25 and the square rod at the same time. When the coarse thread of the threaded rod 51 and the adjusting rod 25 interact with each other to drive the turntable 41 to move upward, the fine thread of the threaded rod 51 drives the top square block 54 to move upward, drives the bottom square block 54 to move downward, and the square block 54 drives the side wing plate 55 to move up and down in the vertical direction, so that the side wing plate 55 drives the inclined rod 56 to move up and down. Because the inclined rod 56 is guided by the inclined hole 46, the inclined rod 56 and the side wing plate 55 slide relative to each other, and then the inclined rod 56 gradually moves out to the outside along the direction of the inclined hole 46, so that the inclined rod 56 drives the roller 57 to move out of the inner side of the storage groove 43, away from the turntable 41 until it contacts the inner side of the large circular groove 62.

[0040] Working principle: The staff first fixes the external motor 15 to be tested on the top of the slide 13, starts the telescopic rod 14 to contract, and drives the motor 15 to be tested to move through the sliding cooperation between the slide 13 and the slide rail 12, and inserts the output end of the motor 15 to be tested into the inner side of the coupling 23 for fixing. Then the staff energizes the motor 15 to make the output end of the motor 15 to be tested drive the shaft 22 to rotate through the coupling 23, and the shaft 22 drives the rotating plate 24 and the adjusting rod 25 to rotate, so that the adjusting rod 25 drives the turntable 41 to rotate. Since the axis of the turntable 41 does not coincide with the axis of the shaft 22, The turntable 41 is in an eccentric shaft state, so that the motor 15 to be tested drives the turntable 41 to rotate the eccentric shaft, and the turntable 41 drives the fixed ring 47 to rotate. Since the fixed ring 47 is coaxial with the center of the turntable 41, the fixed ring 47 also rotates the eccentric shaft. When the fixed ring 47 rotates, it drives the pressure plate 68 to move up and down, and the pressure plate 68 drives the push plate 65 to move up and down, so that the push plate 65 vibrates up and down under the support of the spring 64 and the drive of the pressure plate 68, and then the eccentric shaft vibration simulation test of the motor 15 to be tested is carried out to detect the performance of the motor 15 to be tested in the eccentric shaft vibration working environment;

[0041] After the eccentric shaft vibration simulation test is completed, the motor 15 to be tested is turned off to stop the motor 15 to be tested. Then the staff grabs the rotating rod 53 and rotates it. The rotating rod 53 drives the rotating head 52 and the threaded rod 51 to rotate. The threaded rod 51 rotates and uses the coarse thread and the thread action of the adjustment rod 25 to drive the turntable 41 to move upward, so that the turntable 41 gradually moves to the position where the axis coincides with the axis of the rotating shaft 22. At the same time, the threaded rod 51 uses the fine thread and the thread action of the square block 54 to drive the two square blocks 54 to move away from each other. The square block 54 drives the side wing plate 55 to move up and down in the vertical direction, so that the side wing plate 55 drives the inclined rod 56 to move up and down. The inclined rod 56 is guided by the inclined hole 46 and the side wing plate 55. When the inclined rod 56 moves, it drives the roller 57 to move together, so that the roller 57 gradually approaches the inner wall of the large circular groove 62. When the turntable 41 is coaxial with the rotating shaft 22, the inclined rod 56 drives the roller 57 and the rubber ring 58 to fit with the large circular groove 62. The rubber ring 58 is compressed and deformed under the squeezing of the roller 57 and the large circular groove 62. Then the staff starts the motor 15 to be tested again, so that the motor 15 to be tested drives the turntable 41 to rotate, and the turntable 41 moves coaxially with the rotating shaft 22. The friction between the rubber ring 58 and the large circular ring is used to increase the torque force of the turntable 41, and then the motor 15 to be tested is subjected to a simulation test under torque load to detect the performance of the motor 15 to be tested under the torque working environment.
