Description

Technical Field

[0001] This utility model relates to the field of servo motor processing technology, specifically a sorting servo motor output shaft torque testing bench. Background Technology

[0002] A servo is an actuator used in autopilots to control the rotation of aircraft control surfaces. There are two main types: ① Electric servos, consisting of an electric motor, transmission components, and a clutch. They operate by receiving command signals from the autopilot. When the aircraft is manually piloted, the clutch remains disengaged, and the transmission components are inactive. ② Hydraulic servos, consisting of a hydraulic actuator and a bypass valve. When the aircraft is manually piloted, the bypass valve opens, and the hydraulic pressure on both sides of the actuator piston is interconnected, allowing for unimpeded manual control. In addition, there are electro-hydraulic servos, or simply "electro-hydraulic servos." As a precision drive component, servos are widely used in robotics, model aircraft, and automated equipment. Their output shaft torque is one of the core indicators for evaluating servo performance.

[0003] In practical use, torque testing equipment with similar structures still has many defects, such as: lack of clamping force control function, inability to adjust clamping force according to the material of the test object, which easily leads to insufficient clamping force and clamping overload during test, reducing the safety of the test object and reducing the test efficiency; lack of clamping adjustment function, inability to adjust clamping according to the specifications of the test object, affecting the test range of the device.

[0004] To address the aforementioned issues, existing technologies offer a solution. For example, patent publication number CN222070362U provides a torque testing device, the technical solution of which includes: a top seat, a clamping mechanism, and a base box. The clamping mechanism includes a mounting shaft frame and a threaded clamp. A bidirectional screw is rotatably mounted inside the mounting shaft frame, and two sets of threaded clamps are threaded on the outer side of the bidirectional screw. A pressure sensor is fixedly mounted inside the threaded clamp, and a clamping block is fixedly mounted on one side of the pressure sensor. This invention uses a relatively movable threaded clamp to drive a clamping block to clamp one end of the object being tested. Simultaneously, the clamping block transmits the clamping force to a pressure sensor, which monitors the clamping force in real time. When the controller displays that the clamping force has reached the set value, the operator stops rotating the bidirectional screw, ensuring the clamping force remains within a reasonable range. This improves the safety and efficiency of torque testing. Servo torque testing equipment on the market is generally divided into two categories: one is precision testing equipment based on electronic sensors and control systems. While it can achieve high-precision testing, it is expensive, complex in structure, and has high requirements for the operating environment, making it unsuitable for mass production lines in small and medium-sized enterprises; the other is a simple manual testing device, such as a torque wrench with a fixed bracket. Each test must be conducted manually and the results recorded, resulting in low testing efficiency and the inability to automatically sort the tested components, requiring additional manual screening, increasing production cycle and labor costs.

[0005] To address this, a sorting-type servo motor output shaft torque testing bench is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a sorting-type servo motor output shaft torque testing bench to solve the above-mentioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A sorting-type servo motor output shaft torque testing platform includes a worktable, a testing machine, and a support plate.

The base is hinged to the top plate. The cam is fitted against the bottom of the top plate. The connecting mechanism is connected to the cam. The connecting seat is connected to the connecting mechanism. When the swing cylinder is running, the drive mechanism controls one end of the top plate to lift, pushing the servo motor to an inclined state. As the inclination angle of the servo motor gradually increases, the connecting seat drives the connecting mechanism to operate and controls the cam to intermittently strike the top plate to accelerate the servo motor's slide.

[0008] Preferably, the drive mechanism includes a main gear, a secondary gear, a screw, a U-shaped frame, a threaded block, and a piston rod. The main gear is fixedly installed at the output end of the swing cylinder, the secondary gear meshes with the main gear, the screw is fixedly installed at one end of the secondary gear, the U-shaped frame is rotatably connected to the screw, the threaded block is threadedly installed on the outer wall of the screw, the piston rod is hinged to the threaded block, and the connecting seat is hinged to the piston rod.

[0009] Preferably, the gear ratio between the secondary gear and the primary gear is 1:2.

[0010] Preferably, the piston rods are arranged in two sets symmetrically around the center line of the threaded block.

[0011] Preferably, the support plate and the base have a motion groove inside, and the motion groove is "H" shaped.

[0012] Preferably, the base has inclined portions at both ends, and when the top plate is lifted, the top of the top plate and the inclined portions are on the same plane.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: After the inspection is completed, the inspection results are analyzed by the inspection machine. Then, the swing cylinder is controlled to raise the corresponding top plate to push the servo motor. With the help of the inclined part, the servo motor can be separated from the base. At the same time, as the top plate is lifted, the cam rotates and strikes the top plate to generate vibration, which can accelerate the separation of the servo motor from the base and improve the efficiency of servo motor sorting.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the embodiments described below are only some embodiments of the present utility model, and not all of them. If other embodiments are obtained by those skilled in the art without creative effort, they shall fall within the protection scope of the present utility model.

[0019] Reference Figures 1 to 6 A sorting-type servo motor output shaft torque testing bench includes a worktable 1, a testing machine 2, and a support plate 3. It also includes a swing cylinder 4, a drive mechanism 5, a top plate 6, a base 7, a cam 8, a connecting mechanism 9, and a connecting seat 10. The swing cylinder 4 is fixedly installed at the bottom of the support plate 3. The testing machine 2 is electrically connected to the swing cylinder 4. With this configuration, the swing cylinder 4 can be controlled to operate based on the test results after the servo motor testing is completed, thereby controlling the swing cylinder 4 to swing back and forth. The drive mechanism 5 is connected to the swing cylinder 4, the top plate 6 is connected to the drive mechanism 5, and the base 7 is hinged to the top plate 6. A clamping mechanism is provided inside the base 7. Through the clamping mechanism, the servo motor can be clamped during testing. The clamping mechanism prevents the servo from loosening during testing, thus improving its stability and accuracy. The clamping mechanism is connected to the testing machine 2. This design eliminates the need for manual clamping of the servo and allows the clamping mechanism to hold the servo as the testing machine 2 descends. The cam 8 is fitted against the bottom of the top plate 6. The connecting mechanism 9 is connected to the cam 8, and the connecting seat 10 is connected to the connecting mechanism 9. When the swing cylinder 4 operates, the drive mechanism 5 controls one end of the top plate 6 to lift the servo to an inclined position. As the servo's inclination angle gradually increases, the connecting seat 10 drives the connecting mechanism 9 and controls the cam 8 to intermittently strike the top plate 6 to accelerate the servo's descent.

[0020] As one embodiment of this utility model, refer to Figures 3 to 5The drive mechanism 5 includes a main gear 51, a secondary gear 52, a screw 53, a flange 54, a threaded block 55, and a piston rod 56. The main gear 51 is fixedly mounted on the output end of the swing cylinder 4. The secondary gear 52 meshes with the main gear 51. The screw 53 is fixedly mounted on one end of the secondary gear 52. The flange 54 is rotatably connected to the screw 53. The threaded block 55 is threaded onto the outer wall of the screw 53. The piston rod 56 is hinged to the threaded block 55. The connecting seat 10 is hinged to the piston rod 56. The gear ratio between the secondary gear 52 and the main gear 51 is 1:2. Through the above arrangement, the secondary gear 52 can operate at a faster speed. The rotation allows the threaded block 55 to move back and forth within a certain time, thereby resetting the threaded block 55 to facilitate the sorting of the next servo. Two sets of piston rods 56 are symmetrically arranged around the center line of the threaded block 55. The support plate 3 and the base 7 have motion grooves 57 inside, which are "H" shaped. Through the above arrangement, the two piston rods 56 can be provided with motion space. Both ends of the base 7 are provided with inclined parts 58. When the top plate 6 is lifted, the top of the top plate 6 and the inclined part 58 are on the same plane. Through the above arrangement, the tilted servo can be smoothly slid off the base 7.

[0021] As one embodiment of this utility model, refer to Figure 6 The connecting mechanism 9 includes a fixed plate 91, a telescopic rod 92, a connecting rod 93, a drive gear 94, and an arc rack 95. The fixed plate 91 is fixedly installed at one end of the cam 8, the telescopic rod 92 is fixedly installed between the fixed plate 91 and the cam 8, the connecting rod 93 is fixedly installed at one end of the fixed plate 91, the drive gear 94 is fixedly installed at one end of the connecting rod 93, and the arc rack 95 meshes with the drive gear 94. The telescopic rod 92 is circumferentially arranged with four sets. Through the above arrangement, a rigid connection between the cam 8 and the top plate 6 can be avoided, so that the cam 8 has a certain elasticity when it abuts against the top plate 6, thereby increasing the amplitude of vibration.

[0022] Working principle: When in use, the user places the servo on the base 7, and then controls the detection machine 2 to descend. When the detection machine 2 descends, it drives the clamping mechanism to clamp the servo. Then the detection machine 2 connects with the servo to detect the servo. After the servo motor test is completed, the testing machine 2 tests the quality of the servo motor. After the test, it controls the swing cylinder 4 to run. When the swing cylinder 4 runs, it drives the main gear 51 to rotate. When the main gear 51 rotates, it drives the secondary gear 52 to rotate. When the secondary gear 52 rotates, it drives the screw 53 to rotate. When the screw 53 rotates, it drives the threaded block 55 to move in the motion groove 57. This allows a piston rod 56 to push the corresponding top plate 6. When the top plate 6 is pushed, it can gradually tilt, thereby lifting one end of the servo motor. When the servo motor is lifted, it can drive the connecting seat 10. When the connecting seat 10 tilts synchronously, it can drive the drive gear 94 to mesh with the arc rack 95, thereby driving the drive gear 94 to rotate. When the drive gear 94 rotates, it can drive the fixed plate 91 to rotate through the connecting rod 93. When the fixed plate 91 rotates, it can drive the cam 8 to rotate through the telescopic rod 92. When the cam 8 rotates, it can squeeze the telescopic rod 92 and knock on the top plate 6, thereby causing the top plate 6 to vibrate, so as to accelerate the sorting of the servo motor. Meanwhile, the other piston plate will be stretched while the threaded block 55 moves to prevent the other fixed plate from being pushed up.
