Technical Field

[0001] The present invention relates to the technical field of servo motor production, in particular to a servo motor testing device. Background Art

[0002] A servo motor tester is a device used to inspect and evaluate the performance of servo motors. Servo motors are commonly used in applications requiring precise control, such as robotics, CNC machine tools, and automated production lines. The tester simulates the operation of a servo motor in a real-world environment and verifies the motor's performance, efficiency, stability, and response speed through various tests.

[0003] In the prior art, some servo motor testing devices, when testing the motor, will only display as unqualified even if the quality of the tested servo motor passes the inspection, and cannot mark the servo motor according to the corresponding inspection steps. This requires re-evaluation of the fault point of the servo motor during subsequent rework of the servo motor, which not only increases the extra workload but also makes the rework process more complicated and tedious. Due to the lack of clear fault markings, technicians need to spend more time to check the potential problems of the motor one by one, which increases the rework time and reduces work efficiency. To this end, we propose a servo motor testing device. Summary of the Invention

[0004] The purpose of the present invention is to provide a servo motor testing device to solve the problem proposed in the above background technology that the servo motor cannot be marked according to the corresponding detection steps, and the fault point of the servo motor needs to be re-evaluated subsequently, which increases the extra workload and makes the rework process more complicated and tedious, increases the rework time, and reduces work efficiency.

[0007] The bottom end of the base is fixedly connected to a fixing seat, the interior of the fixing seat is fixedly connected to a cylinder, the driving end of the cylinder is fixedly connected to an extrusion strip, and the outer side of the extrusion strip is slidably connected to the interior of the two mounting seats.

[0008] The marking mechanism includes a fixed plate fixedly connected to the top of the base, and a rotating bar is rotatably connected to the right side of the fixed plate.

[0009] The top end of the rotating bar is slidably connected to a driving boss 1, the outer side of the driving boss 1 is fixedly connected to a sliding rod 1, and the left side of the sliding rod 1 is fixedly connected to a rotating wheel.

[0010] Among them, the outer side of the rotating wheel is provided with a push spring 2, the inner bottom end of the rotating bar is slidably connected to the driving boss 2, and the outer side of the driving boss 2 is fixedly connected to the sliding rod 2.

[0018] The fixing mechanism 4 includes two mounting seats 401 fixedly connected to the top of the base 1. The mounting seats 401 are designed to facilitate the installation of clamping blocks 402 and other structures. The insides of the two mounting seats 401 are slidably connected with clamping blocks 402. The clamping blocks 402 are designed to fix the motor 3 when the extrusion bar 407 is squeezed. The far ends of the two clamping blocks 402 are fixedly connected with sliding columns 403. The sliding columns 403 are designed to facilitate the resetting of the clamping blocks 402 under the push of a push spring 1 404. The outer sides of the two sliding columns 403 are provided with a push spring 1 404. The push spring 1 404 is designed to push the sliding column 403.

[0019] The bottom end of the base 1 is fixedly connected to a fixing seat 405, which is designed to facilitate the installation of a cylinder 406. The interior of the fixing seat 405 is fixedly connected to a cylinder 406, which is designed to facilitate the pushing of an extrusion bar 407. The driving end of the cylinder 406 is fixedly connected to an extrusion bar 407, which is designed to squeeze the two clamping blocks 402 when pushed by the cylinder 406, thereby fixing the motor 3. The outer side of the extrusion bar 407 is slidably connected to the inside of the two mounting seats 401.

[0020] The marking mechanism 9 includes a fixed plate 901 fixedly connected to the top of the base 1. The fixed plate 901 is designed to facilitate the installation of other structures on the marking mechanism 9. The right side of the fixed plate 901 is rotatably connected to a rotating bar 902. The rotating bar 902 is designed to facilitate the connection between the sliding rod 1 904 and the sliding rod 2 908 by driving the boss 1 903 and the boss 2 907.

[0021] The inner top end of the rotating bar 902 is slidably connected to a driving boss 1 903. The driving boss 1 903 is designed to facilitate the rotating bar 902 to drive the sliding rod 1 904. The outer side of the driving boss 1 903 is fixedly connected to a sliding rod 1 904. The sliding rod 1 904 is designed to drive the rotating wheel 905 driven by the driving boss 1 903. The left side of the sliding rod 1 904 is fixedly connected to a rotating wheel 905. The rotating wheel 905 is designed to drive the rotating bar 902 under the extrusion of the extrusion bevel 912.

[0022] The outer side of the rotating wheel 905 is provided with a push spring 2 906, which is designed to push the sliding rod 1 904, thereby resetting the sliding rod 1 904. The inner bottom end of the rotating bar 902 is slidably connected to the driving boss 2 907, which is designed to connect the rotating bar 902 and the sliding rod 2 908. The outer side of the driving boss 2 907 is fixedly connected to the sliding rod 2 908, which is designed to connect the rotating bar 902 and the marking pen 1 909 through the driving boss 2 907.

[0023] The left side of the sliding rod 2 908 is fixedly connected with a marking pen 1 909. The marking pen 1 909 is a pen for marking the appearance of the motor 3. Its color is different from the color of the marking pen 2 911. When the rotation accuracy of the motor 3 matches the tester 7, the marking pen 1 909 will mark the appearance of the motor 3. An electric push rod 910 is installed on the right side of the fixed plate 901. The electric push rod 910 is designed to push the marking pen 2 911. After the load capacity of the motor 3 meets the standard, the marking pen 2 911 marks the motor 3. The driving end of the electric push rod 910 is fixedly connected with the marking pen 2 911. After the marking pen 2 911 marks the motor 3, it means that the load capacity of the motor 3 is passed. The outer side of the lifting seat 6 is fixedly connected with an extrusion bevel 912. The extrusion bevel 912 is designed to squeeze the rotating wheel 905, thereby pushing the sliding rod 904. When the rotation accuracy and load capacity of the motor 3 need to be tested, the motor 3 is docked with the plug 2. After the motor 3 is docked, the indicator light 10 lights up. At this time, the cylinder 406 will push the extrusion bar 407, allowing the extrusion bar 407 to squeeze the two clamping blocks 402, allowing the two clamping blocks 402 to fix the motor 3. At this time, the plug 2 will adjust the rotation angle of the motor 3 so that the groove at the driving end of the motor 3 after the rotation angle is aligned with the protrusion of the tester 7. At this time, the lifting frame 5 will drive the lifting seat 6 and the tester 7 to fall. When the rotation accuracy of the motor 3 is no problem, the protrusion on the extrusion sensor 8 will engage with the groove at the driving end of the motor 3, and the extrusion The inclined block 912 will also squeeze the rotating wheel 905, and the rotating wheel 905 will drive the sliding rod 1 904, thereby driving the driving boss 1 903, so that the driving boss 1 903 drives the rotating bar 902 to rotate, and the rotating bar 902 that is driven to rotate will drive the driving boss 2 907, thereby driving the sliding rod 2 908 and the marking pen 1 909, so that the marking pen 1 909 marks the surface of the motor 3, thereby indicating that the rotation accuracy of the motor 3 meets the standard. When the rotation accuracy of the motor 3 does not meet the standard or the driving end of the motor 3 cannot rotate, the protrusion on the tester 7 and the groove on the driving end of the motor 3 cannot be engaged. At this time, squeezing the inclined block 912 cannot squeeze the rotating wheel 905, and the squeezing sensor 8 will also sense the squeezing of the tester 7. At this time, the lifting frame 5 will not drive the lifting seat. 6 and the tester 7 go down, and the speaker 11 will also sound, then the next step can be carried out to test the load capacity of the motor 3. When the load of the motor 3 meets the standard, the electric push rod 910 will push the marking pen 2 911 to mark the surface of the motor 3. At this time, the test of the load capacity of the motor 3 is completed. In this way, when there are no two different colored marks of marking pen 2 911 and marking pen 1 909 on the surface of the motor 3, it means that there is a problem with the rotation accuracy of the motor 3. When there is a mark of marking pen 1 909 on the motor 3 but no mark of marking pen 2 911, it means that the load capacity of the motor 3 does not meet the standard. When there are marks of different colors of marking pen 1 909 and marking pen 2 911 on the motor 3, it means that the rotation accuracy and load capacity of the motor 3 meet the standard.By using marker pen 1 909 and marker pen 2 911 to mark the surface of motor 3 with different colors, the fault point of motor 3 can be marked, allowing technicians to distinguish the fault type more intuitively. This saves technicians the extra work of distinguishing the fault point of motor 3, reduces workload, simplifies the rework process, shortens rework time, and improves work efficiency.

[0024] Example 2 In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that a display light 10 is installed on the top of the base 1. The display light 10 is designed to show whether the motor 3 and the plug 2 are correctly connected. A speaker 11 is installed on the top of the base 1. When the motor 3 does not meet the detection standards, the speaker 11 will sound a reminder.
