[0002] As a driving control element, motors are widely used in various fields. A piece of equipment often requires multiple motors. Once a motor fails, it will lead to equipment and system failures, which will cause huge economic losses in the industrial field. Therefore, the durability of motors has become a major issue in the field of modern technology and has attracted much attention. Among them, when conducting sampling standard tests on stepper motors, special attention is paid to the driving ability and motion continuity of stepper motors.

[0003] When performing performance testing on existing motors, it is necessary to install another motor to connect the output shaft of the motor being tested. This test method is called "complementary test" or "comparative test". During the connection, a connector is usually used.

[0042] Embodiment 2:

[0043] On the basis of embodiment one, the driving assembly includes a positioning plate 15, which is fixedly mounted on the lower end surface of the workbench 2 and is located on the outer side of the mounting plate 9.

A driven gear 24 is fixedly mounted on the first threaded cylinder 20 and the second threaded cylinder, and the driving gear 18 is meshed with the driven gear 24. The internal structure of the first threaded cylinder 20 and the second threaded cylinder 21 is an internal thread, and the first threaded rod 22 and the second threaded rod 23 are driven to move through the internal thread. Since this technology is well known to people in this field, it will not be described in detail here.

[0045] The clamping assembly includes two symmetrically installed L-shaped plates 25, and the two L-shaped plates 25 are fixedly installed on the second mounting slider 4.

[0047] Embodiment three:

[0048] On the basis of the first embodiment, a fastening assembly is provided on the rotating block 11, and the fastening assembly includes a plurality of mounting frame plates 28, and the plurality of mounting frame plates 28 are fixedly mounted on the connecting head 12, and a rotating shaft 29 is rotatably mounted inside the plurality of mounting frame plates 28, and an extrusion plate 30 is fixedly mounted on the rotating shaft 29, and a torsion spring 32 is fixedly mounted on the extrusion plate 30, and one end of the torsion spring 32 away from the extrusion plate 30 is fixedly mounted on the mounting frame plate 28, and the position of the torsion spring 32 is on the outside of the rotating shaft 29, and the end of the extrusion plate 30 is set to an arc surface, and the arc surface facilitates the active output shaft 7 and the driven output shaft 8 to push the closed extrusion plate 30 outward.

[0049] In this embodiment, when the active output shaft 7 is inserted into the first positioning hole 13 and the driven output shaft 8 is inserted into the second positioning hole 14, the extrusion plate 30 located outside the first positioning hole 13 and the second positioning hole 14 will be rotated outward by the push of the active output shaft 7 and the driven output shaft 8. When the active output shaft 7 and the driven output shaft 8 are fully inserted into the first positioning hole 13 and the second positioning hole 14, the extrusion plate 30 will fit on the active output shaft 7 and the driven output shaft 8 through the torsion force of the torsion spring 32, thereby improving the firmness between the active output shaft 7 and the first positioning hole 13 and the driven output shaft 8 and the second positioning hole 14, so that the test motor 6 will not fall off during the test, thereby improving the practicality of the device.

[0050] Working principle:

[0051] When in use, the test motor 6 is placed on the second mounting slide block 4, and the clamping block 27 is driven to move inward by the electric push rod 26, so that the test motor 6 is installed on the second mounting slide block 4, and the connector 12 on the turntable 10 is selected according to the size of the driven output shaft 8 on the test motor 6;

[0052] When selecting, the fastening bolt 47 is rotated to disengage the fastening bolt 47 from the threaded hole 48 on the turntable 10, and the turntable 10 is rotated to make the selected connector 12 and the driven output shaft 8 of the test motor 6 be in the same horizontal plane, and then the fastening bolt 47 is reinstalled in the threaded hole 48 of the turntable 10 to complete the position fixation of the turntable 10;

[0053] Then, the first driving motor 16 drives the rotating shaft 17 to rotate. When the rotating shaft 17 rotates, it drives the two driving gears 18 to rotate. The driving gear 18 is meshed with the driven gear 24. When the driven gear 24 rotates, it drives the first threaded cylinder 20 and the second threaded cylinder 21 to rotate on the two vertical plates 19 respectively. When the first threaded cylinder 20 rotates, the first threaded rod 22 rotates and moves horizontally. When the first threaded cylinder 20 moves, the first threaded rod 22 pushes the first mounting slide block 3 to move toward the position of the turntable 10. At the same time, when the second threaded cylinder 21 rotates, the second threaded rod 23 rotates and moves horizontally. When the second threaded rod 23 moves, the second threaded rod 23 pushes the second mounting slide block 4 to move toward the position of the turntable 10. When the first mounting slide block 3 and the second mounting slide block 4 move, the active output shaft 7 on the main control motor 5 is inserted into the first positioning hole 13 of the connector 12, and the driven output shaft 8 on the test motor 6 is inserted into the second positioning hole 14 of the connector 12. At this time, the first driving motor 16 is stopped;

[0054] During the test, the second driving motor 33 drives the rotating rod 34 to rotate, and the rotating rod 34 drives the cam 35 to rotate when rotating. When the cam 35 rotates a certain angle, it pushes the lifting plate 37 in the first lifting slot 38 and the second lifting slot 39 to rise. When the lifting plate 37 is not pushed by the cam 35, the lifting plate 37 will be in a shaking state through the elasticity of the first spring 40 and the second spring 41. Since the lifting plate 37 is installed on the workbench 2, the workbench 2 is in a shaking state. Through the shaking state, the test motor 6 can perform better performance testing.

[0055] In this technical solution, the first lifting slot 38 and the second lifting slot 39 are not compatible with the lifting plate 37, and the stabilizing slot 44 is not compatible with the stabilizing plate 42. When the lifting plate 37 is lifted and lowered in the first lifting slot 38 and the second lifting slot 39, it will be in a shaking state due to the elastic force of the spring, and when detecting the motor performance, it is necessary to connect the output shaft of the motor under test through another motor (called the "reference motor"). This method is called "complementary test" or "comparison test", in which the purpose of the complementary test is to connect the reference motor to the motor under test to detect whether the performance of the motor under test is the same as that of the reference motor. If the performance of the motor under test is the same as that of the reference motor, then it can be judged that the performance of the motor under test is normal.

[0056] The control method in this technology is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field. In addition, this application is mainly used to protect mechanical devices, so this technical solution no longer explains the motor control method and circuit connection relationship in detail.

[0057] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
