Description

Technical Field

[0001] This invention relates to the field of encoder testing technology, and more specifically to a motor encoder calibration and testing device. Background Technology

[0002] As a core detection component for servo motors and stepper motors, motor encoders are key basic components in fields such as industrial automation, intelligent manufacturing, and new energy equipment. Their speed and angular displacement acquisition accuracy directly determines the control accuracy of the motor and the stability of equipment operation.

[0003] Chinese patent CN221549736U discloses an encoder testing device, including a frame, a platform in the middle of the frame, a detection drive assembly on the front of the platform, an oscilloscope box on the top rear side of the platform, an instrument compartment inside the frame below the platform, a wiring assembly on the top of the platform, an input platform extending out of the frame on the front side of the platform, and a display for displaying test information on the front top of the frame. The detection drive assembly includes a clamping assembly on the top of the platform, a clamping assembly on the platform, and a rotary drive assembly below the platform for driving the clamping assembly to rotate. However, this device still has the following problems in use: The device has a fixed-specification snap-fit ​​structure, which can only be used with a single type of encoder.

Improper encoder placement can easily lead to poor contact between the acquisition probe and the data terminal, resulting in distorted test results. Furthermore, the device only acquires the output data of the encoder under test and cannot verify whether the test results are the same as the output of the drive device, thus failing to achieve accurate testing.

[0011] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0012] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0013] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8 A motor encoder calibration and testing device includes a cabinet 1, a pressure-type testing mechanism 2, a fault-proof multi-directional clamping mechanism 3, an autonomous leveling mechanism 4, and a movable base plate 5. An autonomous leveling mechanism 4 for controlling the horizontal position of the movable base plate 5 is installed in the middle of the cabinet 1. The pressure-type detection mechanism 2, used for automatically testing whether the data reading status of the encoder is normal, is installed on the upper rear side of the movable base plate 5. The pressing detection mechanism 2 includes a pressing component and a rotating component; the pressing component is installed on the upper end of the movable base plate 5; the rotating component is connected to the pressing component; A multi-directional clamping mechanism 3 for calibrating and clamping the encoder's position is installed on the upper front side of the movable base plate 5. The error-proof multi-directional clamping mechanism 3 includes a bearing component, a self-locking separation limiting component, and a lateral limiting component; the bearing component is connected to the movable base plate 5; the lateral limiting components are symmetrically installed on the front and rear sides of the bearing component; the self-locking separation limiting component is connected to the bearing component; The carrier component is also equipped with a probe that communicates with the encoder data terminal for data acquisition; a central control unit (not shown in the diagram) is fixedly installed on the cabinet 1; the probe is connected to the central control unit for communication. In this invention, the loading robot places the motor encoder to be tested into the carrier component, and the carrier component ensures that the encoder is correctly positioned and oriented, ensuring that the motor encoder is always installed on the carrier component in the same state, preventing any impact on the test results and improving the accuracy of the test results. Then the lateral limiting component moves towards the motor encoder from the front and rear direction until the lateral limiting component contacts and abuts against the front and rear ends of the motor encoder, thereby achieving a secondary calibration of the encoder's posture. The self-locking separation limit component is then installed on the carrier component. The self-locking separation limit component will automatically fix itself on the carrier component and limit the left and right sides and the top of the motor encoder, further improving the accuracy of the test results. Furthermore, the lateral limiting component can also limit encoders of different sizes, making it adaptable to a wide range of applications and further enhancing the practicality of the device. Subsequently, the pressing component controls the rotating component to move downwards until the rotating component connects with the encoder shaft. Then, the rotating component controls the encoder shaft to rotate. During the rotation, the rotating component can self-test its own rotational speed and angular displacement. By comparing the rotational speed and angular displacement collected by the probe with those collected by the encoder under test, it can determine whether the encoder's acquisition function is normal. In addition, the operator can also adjust the horizontal position of the movable base plate 5 through the self-leveling mechanism 4 to ensure that the rotating component can maintain precise alignment with the encoder shaft, further improving the testing accuracy of the encoder under test.

[0014] Example 2: In some embodiments, such as Figures 4-8 As shown, in a preferred embodiment of the present invention, the self-leveling mechanism 4 includes a drive bolt 41, a leveling nut 42, a locking nut 43, and a fixing sleeve 44; a plurality of fixing sleeves 44 are fixedly installed in a rectangular array at the lower end of the movable base plate 5. The lower ends of multiple drive bolts 41 are arranged in a rectangular array and rotate in the middle of the cabinet 1; the leveling nut 42 and the locking nut 43 are both threadedly connected to the drive bolts 41. The upper end of the drive bolt 41 is connected to the internal thread of the fixed sleeve rod 44; In this invention, when it is necessary to calibrate the horizontal state of the movable base plate 5, the operator first uses a wrench to rotate the locking nut 43 to move it downward along the fixed sleeve 44, and then rotates the leveling nut 42 to move it upward along the fixed sleeve 44 until the leveling nut 42 and the locking nut 43 are pressed together in the middle of the fixed sleeve 44. If it is necessary to raise the height of the movable base plate 5, continue to turn the leveling nut 42. At this time, the leveling nut 42 will be blocked by the locking nut 43, so that the fixing sleeve rod 44 will rotate with the leveling nut 42. At this time, the fixing sleeve rod 44 will drive the driving bolt 41 to move the movable base plate 5 upward. Similarly, when it is necessary to lower the height of the movable base plate 5, the locking nut 43 is turned so that the fixing sleeve rod 44 rotates in the opposite direction, so that the fixing sleeve rod 44 drives the driving bolt 41 to move the movable base plate 5 downward. This ensures that the encoder under test, placed on the movable base plate 5, remains horizontal, thereby guaranteeing the accuracy of the test results. The supporting component includes a mounting frame 31 and an annular fixing plate 314; the mounting frame 31 is fixedly installed on the upper end of the movable base plate 5; the middle of the mounting frame 31 is provided with a receiving groove 32 for accommodating the encoder housing; the annular fixing plate 314 is fixedly installed on the upper middle part of the mounting frame 31; the left and right sides of the annular fixing plate 314 are symmetrically provided with directional limiting grooves 33 for distinguishing the orientation of the encoder. The probe for data acquisition, which is connected to the encoder data terminal, is fixedly installed on the upper left side of the annular fixing plate 314; In this invention, the loading robot places the motor encoder to be tested into the receiving slot 32, and the data terminals on the encoder are plugged into the annular fixing plate 314; and through the directional limiting slot 33, it ensures that the motor encoder is always installed on the bearing component in the same state, preventing the test results from being affected and improving the accuracy of the test results. Then the lateral limiting component moves towards the motor encoder from the front and rear direction until the lateral limiting component contacts and abuts against the front and rear ends of the motor encoder, thereby achieving a secondary calibration of the encoder's posture. The self-locking separation limit component is then installed on the carrier component. The self-locking separation limit component will automatically fix itself on the carrier component and limit the left and right sides and the top of the motor encoder, further improving the accuracy of the test results. Furthermore, the lateral limiting component can also limit encoders of different sizes, making it adaptable to a wide range of applications and further enhancing the practicality of the device. like Figure 7 and Figure 8As shown, the self-locking separation limiting assembly includes a contoured pressure plate 39, a driving inclined plate 310, a snap-fit ​​plate 311, and a reset spring 313; the upper end of the mounting bracket 31 has multiple slots 38 arranged in a rectangular array at equal intervals. The lower end of the contour plate 39 is slidably connected to multiple slots 38 for limiting; The drive ramp 310 is symmetrically fixed at both ends of the mounting bracket 31; the upper end of the drive ramp 310 is provided with a drive ramp 315. The snap-fit ​​plate 311 is symmetrically rotated and installed at both ends of the contour pressure plate 39; the lower end of the snap-fit ​​plate 311 is provided with a driven inclined surface 312 that cooperates with the driving inclined surface 315. One end of the reset spring 313 is fixedly connected to the snap-fit ​​plate 311; the other end of the reset spring 313 is fixedly connected to the contour plate 39. The reset spring 313 ensures that the two locking plates 311 on the left and right always tend to rotate downwards. The lateral limiting assembly includes a hydraulic cylinder 34, a pressure block 35, a support rotating plate 36, and an adjusting roller 37; the hydraulic cylinder 34 is fixedly connected to the mounting bracket 31; the output end of the hydraulic cylinder 34 is hinged to one end of the support rotating plate 36; one end of the pressure block 35 is hinged to the upper outer shell of the hydraulic cylinder 34; and the other end of the support rotating plate 36 is hinged to the middle of the pressure block 35. An adjusting roller 37 is rotatably installed at one end of the two pressure blocks 35 that are close to each other; In this invention, after the encoder is placed in the receiving slot 32, the hydraulic cylinder 34 works to push the support rotating plate 36 to rotate upward. The upward movement of the support rotating plate 36 will drive the pressure block 35 to rotate upward around the hinge point with the hydraulic cylinder 34. During the rotation process, the adjusting rollers 37 installed at the close end of the two pressure blocks 35 will contact the front and rear ends of the encoder to be tested, so as to realize the secondary calibration of the encoder's posture until the front and rear adjusting rollers 37 are pressed against the encoder. Then the contour plate 39 is inserted downward along the slot 38. During the movement, the driving slope 315 at the upper end of the driving slope 310 will contact the driven slope 312 at the lower end of the snap-fit ​​plate 311, thereby controlling the snap-fit ​​plate 311 to rotate upward around the hinge point with the contour plate 39. Until the driven inclined plane 312 separates from the driving inclined plane 315, the reset spring 313 returns to its original position, causing the snap-fit ​​plate 311 to rotate downwards and reset, so that the snap-fit ​​plate 311 snaps into the driving inclined plate 310, thereby fixing the contour plate 39; and the contour plate 39 also limits and fixes the upper end of the encoder, further improving the accuracy of the test results.

[0015] Example 3: In some embodiments, such as Figures 4-6As shown, in a preferred embodiment of the present invention, the pressing assembly includes a vertical plate 21, a servo slide module 22, a linear guide module 23, and an integrated plate 24; the vertical plate 21 is fixedly installed on the upper rear side of the movable base plate 5; the servo slide module 22 is fixedly installed on the front end of the vertical plate 21; the guide rails of the linear guide module 23 are symmetrically fixedly installed on the left and right sides of the front end of the vertical plate 21. The integrated board 24 is fixedly connected to the moving end of the servo slide module 22 and the slider of the left and right linear guide rail module 23; Integrated board 24 is connected to the rotating assembly; The rotating assembly includes a test motor 25, a first coupling 26, a drive shaft 27, a test connecting block 28, a smart sensor, and a second coupling 210; the test motor 25 is fixedly mounted on the upper front end of the integrated plate 24; the test connecting shaft 211 is rotatably mounted on the middle front end of the integrated plate 24. The upper end of the test connecting shaft 211 is connected to the output end of the test motor 25 via the first coupling 26; the lower end of the test connecting shaft 211 is connected to the drive shaft 27 via the second coupling 210. A smart sensor for monitoring the rotational speed and angular displacement of the test connection shaft 211 is fixedly mounted in the middle of the front end of the integrated board 24; The intelligent sensor uses a hollow shaft encoder 29; the hollow shaft encoder 29 uses mature technology in the industry, such as the Autonics E80H series hollow shaft encoder. The drive shaft 27 is mounted on the lower front end of the integrated plate 24. The test connection block 28 is fixedly connected to the drive shaft 27; the lower end of the test connection block 28 has a countersunk hole for connecting to the encoder shaft under test; The inner wall of the countersunk hole is provided with textures to increase the friction with the shaft of the encoder under test; In this invention, the servo slide module 22 controls the integrated board 24 to move downward along the linear guide module 23, thereby causing the test connection block 28 to move downward until the countersunk hole at the lower end of the test connection block 28 is inserted into the shaft of the encoder to be tested. Subsequently, the test motor 25 controls the first coupling 26 to drive the test connecting shaft 211 to rotate, and the test connecting shaft 211 drives the drive shaft 27 to rotate through the second coupling 210, thereby causing the shaft of the encoder under test to rotate. During rotation, the hollow shaft encoder 29 can perform self-testing on the rotational speed and angular displacement of the test connecting shaft 211. By comparing the rotational speed and angular displacement collected by the probe with those collected by the encoder under test, it can determine whether the acquisition function of the encoder under test is normal, thereby further improving the test accuracy of the encoder under test.
