Description

Technical Field

[0001] This utility model relates to the field of motor encoder technology, and more specifically, to a calibration device for a magnetic encoder of a servo motor. Background Technology

[0002] With the rapid development of industrial automation, robotics, and precision machinery, the requirements for the control precision, response speed, and reliability of servo motors are becoming increasingly stringent. As an actuator, the precision and performance of the servo motor directly affect the control effect of the entire system, and the accuracy of the magnetic encoder, as a key position feedback element of the servo motor, is paramount. Therefore, a precise calibration device is needed to ensure that the output of the magnetic encoder accurately corresponds to the actual position of the motor, in order to meet the requirements of high-precision control.

[0003] In standard testing procedures, the motor under test is typically fixed to a motor mount with screws. After the testing process is completed, the screws need to be loosened to remove the motor. However, in mass production scenarios, the frequent tightening and loosening of screws makes the entire process cumbersome and significantly impacts production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a magnetic encoder calibration device for servo motors. This device uses a wide-seat pneumatic gripper to save auxiliary time and improve efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A calibration device for a magnetic encoder of a servo motor includes a housing, a drive servo motor, a servo motor under test, a coupling, a clamping structure, and a protective structure. The drive servo motor is fixed inside the housing; the clamping structure is located outside the housing and clamps the servo motor under test; the servo motor under test is connected to the drive servo motor via the coupling; and the protective structure is movably disposed on the front side of the housing.

[0007] Preferably, the outer casing includes a base plate, a right side plate, a left side plate, and a tabletop. The right side plate and the left side plate are fixed to both sides of the base plate, the tabletop is fixed to the top of the right side plate and the left side plate, and the clamping structure is fixed to the upper surface of the tabletop.

[0008] Preferably, one end of the drive servo motor is fixed to the upper part of the base plate, and the other end is fixed to the lower end of the motor base, with the upper end of the motor base fixed to the table surface.

[0009] Preferably, the clamping structure includes a wide-seat pneumatic gripper, a left clamping plate, a right clamping plate, a manual valve, and an air source processor. The left clamping plate and the right clamping plate are respectively fixed on both sides of the wide-seat pneumatic gripper, and the manual valve and the air source processor are both fixed on the left side plate.

[0010] Preferably, the protective structure includes a sliding door, a cylinder, a slider, and a slide rail, wherein the sliding door slides on the slide rail via the slider.

[0011] Preferably, the right side plate and the left side plate have heat dissipation holes.

[0012] Preferably, protective pads are provided on the left and right clamping plates respectively.

[0013] Furthermore, compared to existing technologies, this invention has the following advantages: it abandons the traditional method of fixing the servo motor with screws and adopts a wide-seat pneumatic gripper design. This method avoids the tedious tightening and calibration steps required when using screws, greatly saving auxiliary time during equipment installation and debugging, and effectively improving overall efficiency.

Detailed Implementation

[0020] 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figure 1-5As shown, the device includes a housing 100, a drive servo motor 2, a servo motor under test 9, a coupling 3, a clamping structure 200, and a protective structure 300. The drive servo motor 2 is fixed inside the housing 100; the clamping structure 200 is mounted outside the housing 100 and clamps the servo motor under test 9; the servo motor under test 9 is connected to the drive servo motor 2 via the coupling 3; the protective structure 300 is movably mounted on the front side of the housing 100, providing safety protection and effectively preventing external objects or personnel from accidentally contacting the high-speed rotating components inside the device.

[0022] The outer casing includes a base plate 1, a right side plate 5, a left side plate 13, and a tabletop 6. The right side plate 5 and the left side plate 13 are fixed to both sides of the base plate 1, and the tabletop 6 is fixed to the top of the right side plate 5 and the left side plate 13. The clamping structure 200 is fixed to the upper surface of the tabletop 6.

[0023] One end of the drive servo motor 2 is fixed to the upper part of the base plate 1, and the other end is fixed to the lower end of the motor base 4. The upper end of the motor base 4 is fixed to the table surface 6. Through the multi-point fixation of the base plate 1, the motor base 4 and the table surface 6, a stable support is provided for the drive servo motor 2, ensuring that the motor can maintain a stable position during operation, avoiding the motor from shifting or tipping over due to vibration or external force generated by the motor operation, and ensuring the normal operation and safety of the device.

[0024] The clamping structure 200 includes a wide-seat pneumatic gripper 10, a left clamping plate 11, a right clamping plate 8, a manual valve 12, and an air source processor 14. The left clamping plate 11 and the right clamping plate 8 are respectively fixed on both sides of the wide-seat pneumatic gripper 10. The manual valve 12 and the air source processor 14 are both fixed on the left side plate 13. The left clamping plate 11 and the right clamping plate 8 are respectively fixed on both sides of the wide-seat pneumatic gripper 10. The structure can be adjusted appropriately according to the size of the servo motor 9 under test to accommodate motors of different specifications, thus expanding the applicability of the device. Before testing, the manual valve 12 is activated, and the wide-seat pneumatic gripper 10 clamps the servo motor 9 under test. After the test, the servo motor 9 is driven to stop rotating, and the manual valve 12 is activated again, releasing the wide-seat pneumatic gripper 10.

[0025] The protective structure 300 includes a sliding door 15, a cylinder 16, a slider 17, and a slide rail 18. The sliding door 15 slides on the slide rail 18 via the slider 17. During the test, the cylinder 16 drives the sliding door 15 to close, which can isolate high-speed rotating components such as the drive servo motor 2 and the tested servo motor 9, as well as connecting components such as the coupling 3, from the external space, preventing operators or other objects from accidentally contacting these moving parts, thereby avoiding equipment damage or personnel injury caused by collisions, entanglement, or other accidents.

[0026] The right side plate 5 and the left side plate 13 have heat dissipation holes 19, which generate heat during high-speed operation and dissipate the heat through the heat dissipation holes 19.

[0027] Protective pads 7 are provided on the left clamping plate 11 and the right clamping plate 8 respectively to prevent scratches, indentations or other damage to the motor surface during the clamping process.

[0028] The working principle is as follows:

[0029] In the initial state, the wide-seat pneumatic gripper 10 is open, and the servo motor 9 under test is placed into the motor mount 4;

[0030] The motor shaft of the servo motor 9 under test is inserted into the coupling 3 located under the motor base 4;

[0031] Move the manual valve 12, and the wide-seat pneumatic gripper 10 clamps the servo motor 9 under test;

[0032] The drive servo motor 2 drives the driven servo motor 9 to rotate at different speeds via coupling 3. At this time, cylinder 16 drives sliding door 15 to close, forming a protective structure;

[0033] The testing instrument records the measured data and writes it into the encoder's register;

[0034] The test is complete, and the servo motor 9 stops rotating.

[0035] Move the manual valve 12 to release the wide-seat pneumatic gripper 10 and remove the servo motor 9 under test.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
