Description

Technical Field

[0001] This utility model relates to the field of motor testing technology, and in particular to a dual-station motor performance comprehensive testing platform. Background Technology

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system; it is a type of auxiliary motor with indirect speed control. Servo motors enable highly accurate speed and position control, converting voltage signals into torque and speed to drive the controlled object. The rotor speed of a servo motor is controlled by the input signal and can respond quickly. In automatic control systems, it serves as an actuator and possesses characteristics such as a small electromechanical time constant, high linearity, and low starting voltage. It can convert received electrical signals into angular displacement or angular velocity output on the motor shaft. After the servo motor is assembled, its rotor needs to be rotated at a certain speed to test its performance.

[0003] Existing motor testing machines typically fix the bottom of the servo motor under test directly onto a fixture. This fixed placement causes slight vibrations when the rotor of the servo motor under test is rotated, which affects the accuracy of the servo motor test.

[0004] Therefore, this utility model proposes a dual-station motor performance comprehensive testing platform to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a dual-station motor performance comprehensive testing platform to achieve stable clamping of the servo motor under test, thereby improving the accuracy and efficiency of servo motor testing.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a dual-station motor performance comprehensive test bench for testing the performance of a servo motor under test. Its innovation lies in: the comprehensive test bench includes a platform, on which two test stations are provided. Each test station is provided with a drive servo motor for driving the rotor of the servo motor under test to rotate and a clamping assembly for fixing the servo motor under test. The clamping assembly includes a positioning fixture, a pressure head, and a cylinder. The positioning fixture is fixedly installed on the top surface of the platform. The cylinder is fixedly connected to the platform through a bracket. The pressure head is positioned above the positioning fixture and cooperates with the positioning fixture to form a clamping space for the servo motor under test. The pressure head is connected to the piston rod end of the cylinder through a floating joint and is driven by the cylinder to move up and down away from or towards the positioning fixture. The top surface of the positioning fixture has a positioning connection hole that matches the flange hole of the servo motor under test. The middle of the positioning fixture has a first through hole for the rotor of the servo motor under test to pass downward. The drag servo motor is fixedly mounted on the bottom surface of the platform. The platform has a second through hole. The rotating end of the drag servo motor passes upward through the second through hole. The rotating end of the drag servo motor is equipped with a coupling for connecting the rotor of the servo motor under test.

[0007] Furthermore, the positioning fixture includes a base and a positioning plate. The base is fixedly installed on the top surface of the platform, and the positioning plate is detachably connected to the top surface of the base by bolts. The first through hole and the positioning connection hole are opened on the top surface of the positioning plate.

[0008] Furthermore, the base has a cylindrical structure with its central axis set vertically, and the central axis of the base is on the same straight line as the central axis of the rotating end of the servo motor.

[0009] Furthermore, the coupling is located inside the base, and an operation and observation port is provided on the side wall of the base.

[0010] Furthermore, the integrated test bench also includes a protective housing, with the test plate installed inside the protective housing. The protective housing has a pick-and-place port on one side near the operation observation port for picking up and placing the servo motor under test, and safety light curtains are provided on both sides of the pick-and-place port on the protective housing.

[0011] The advantages of this utility model are: (1) The integrated test bench of this utility model uses the positioning connection hole on the positioning fixture to realize the positioning and bottom fixation of the servo motor under test. Then, the cylinder drives the pressure head to move downward and press against the top of the servo motor under test. The pressure head and the positioning fixture work together to complete the stable clamping of the servo motor under test, which can effectively reduce the vibration of the servo motor under test during testing, thereby improving the accuracy of the servo motor test. In addition, the dual-station design effectively improves the testing efficiency of the servo motor under test.

[0012] (2) The positioning fixture of this utility model adopts a split structure, and different positioning plates can be replaced according to different models of servo motors under test to improve adaptability.

[0013] (3) The base of this utility model adopts a cylindrical structure and the central axis is coaxial with the rotating end of the driving servo motor. This design can effectively disperse the mechanical stress generated by the servo motor under test during the test and improve the test stability.

[0014] (4) By placing the coupling inside the base, this utility model effectively isolates the coupling from the external environment, reducing the risk of personnel contact with rotating parts. It also prevents foreign objects from entering and causing mechanical jamming or damage. The design of the operation observation port allows for condition monitoring and maintenance without completely disassembling the base, balancing safety and convenience. (5) This utility model prevents dust, chips and other foreign objects from entering the test bench by covering the outside of the test bench with a protective shell, protects precision parts from contamination or mechanical damage, and installs a safety light curtain at the pick-up and drop-out port of the protective shell to ensure operational safety.

[0019] Example This embodiment provides a dual-station motor performance comprehensive testing platform, such as... Figure 1-2 As shown, this is used for performance testing of the servo motor 3 under test.

[0020] The integrated test bench includes a protective housing 11 and a platform 4. The platform 4 is installed inside the protective housing 11. The platform 4 has two test stations.

The cylinder 1 is fixedly connected to the platform 4 via a bracket 2. The pressure head 9 is positioned above the positioning fixture 6 and cooperates with the positioning fixture 6 to form a clamping space for the servo motor 3 under test. The pressure head 9 is connected to the piston rod end of the cylinder 1 via a floating joint 10 and is driven by the cylinder 1 to move up and down away from or towards the positioning fixture 6.

[0022] In this embodiment, the positioning fixture 6 includes a base 61 and a positioning plate 62. The base 61 has a cylindrical structure, and its central axis is vertically fixed on the top surface of the platform 4. The top surface of the base 61 has a flange for connecting the positioning plate. The positioning plate 62 is detachably connected to the top surface of the flange of the base 61 by bolts. The top surface of the positioning plate 62 of the positioning fixture 6 has a positioning connection hole that matches the flange hole of the servo motor 3 under test. The positioning plate 62 of the positioning fixture 6 has a first through hole in the middle for the rotor of the servo motor 3 under test to pass downward. The positioning fixture 6 adopts a split structure, and the operator can replace different positioning plates 62 according to different models of servo motors under test to meet the matching requirements of the positioning connection hole of the positioning plate 62 and the servo motor 3 under test.

[0023] The servo motor 7 is fixedly mounted on the bottom surface of the platform 4. A second through hole is provided on the platform 4. The rotating end of the servo motor 7 passes upward through the second through hole into the interior of the base 61. The central axis of the base 61 is collinear with the central axis of the rotating end of the servo motor 7. A coupling 8 for connecting the rotor of the servo motor 3 under test is installed on the rotating end of the servo motor 7. The coupling 8 is located inside the base 61. An operation observation port is provided on the side wall of the base 61, effectively isolating the coupling 8 from the external environment, reducing the risk of personnel contact with rotating parts, and preventing foreign objects from entering and causing mechanical jamming or damage. The design of the operation observation port allows for condition monitoring and maintenance without completely disassembling the base 61, balancing safety and convenience.

[0024] The protective housing 11 has a pick-and-place port on the side near the operation observation port for picking up and placing the servo motor 3 under test. Safety light curtains 14 are provided on both sides of the pick-and-place port on the protective housing 11 to ensure operational safety. The protective housing 11 is also equipped with a display 12 and an ammeter 13 for displaying test data.

[0025] When clamping the servo motor 3 under test on the integrated test bench, the servo motor 3 under test is first inverted on the positioning plate 62 of the positioning fixture 6, so that the rotor of the servo motor 3 under test passes through the first through hole on the positioning plate of the positioning fixture 6 and is connected to the coupling 8. The flange bolts matching the servo motor 3 under test are threaded into the positioning connection hole on the positioning plate 62. The piston rod of the cylinder 1 is activated, driving the pressure head 9 to move downward and press against the top of the servo motor 3 under test. The pressure head 9 and the positioning fixture 6 cooperate to complete the stable clamping of the servo motor 3 under test, effectively reducing the vibration of the servo motor under test during testing, thereby improving the accuracy of the servo motor test. In addition, the integrated test bench adopts a dual-station design, which effectively improves the testing efficiency of the servo motor under test.
