[0002] Servo motors are electric actuators characterized by high precision, high reliability, and fast response. They are commonly used in industrial automation equipment across a wide range of fields, including but not limited to machinery manufacturing, automotive manufacturing, food processing, medical equipment, robotics, and aerospace, playing a vital role in each. In related technologies, to obtain the dimensional parameters of servo motors and ensure that the factory specifications meet design requirements, manual methods are typically used. This involves sequentially measuring dimensional parameters such as shaft extension length and flange thickness, comparing them with standard parameters to determine product qualification. However, this measurement method has drawbacks: manual operation leads to lower accuracy, increasing the risk of defective products being shipped, and the need to measure different parameters multiple times according to a procedure makes the measurement process cumbersome.

[0012] In some embodiments, the receiving groove has a circular outline that matches the flange, and the diameter of the receiving groove is larger than the diameter of the flange; the first mounting hole is located in the central region of the receiving groove.

[0013] In some embodiments, a second mounting hole is further provided at the bottom of the receiving groove, the second mounting hole penetrating the bottom wall of the receiving groove along the height direction; the second indicator is inserted through the second mounting hole and abuts against the flange.

[0017] In some embodiments, the pneumatic connector includes two pneumatic connectors arranged radially opposite each other along the receiving groove.

[0018] According to the motor testing equipment of the above embodiment, since the servo motor is directly placed on the bearing surface of the base, and the self-weight of the servo motor is used to drive the testing device to measure the dimensions of the shaft and flange, the user does not need to manually operate the testing device, which improves the testing efficiency and ensures the accuracy of the testing results, thereby effectively reducing the risk of defective products flowing out.

[0034] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0035] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0036] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0037] In related technologies, the measurement of relevant dimensional parameters of servo motors, such as shaft length and flange thickness, is done manually. For example, for shaft length, operators typically use a depth gauge to manually measure the distance from the end of the shaft to the end face of the motor. This measurement method is prone to errors due to the inaccuracy of manual operation. Moreover, this method can only screen out servo motors with shaft lengths greater than the acceptable size, but cannot accurately identify servo motors with shaft lengths smaller than the acceptable size, thus increasing the possibility of defective products being exported. The same applies to flange thickness measurement. Furthermore, measuring these two dimensional parameters, shaft length and flange thickness, requires operators to follow a procedure sequentially, making the measurement process of the motor testing equipment cumbersome and resulting in low production efficiency.

[0038] To address the issues of inaccurate dimensional measurements in servo motors, high defect rates, and cumbersome measurement processes in related technologies, this application provides a motor testing device. Please refer to [link / reference needed]. Figures 1 to 3 As shown, the motor testing equipment includes:

[0039] The base 1 has a bearing portion 10, the bearing portion 10 has a bearing surface 11, the bearing surface 11 has a recessed receiving groove 13, and a first mounting hole 12 is provided through the bottom of the receiving groove 13 along the height direction; the first mounting hole 12 is used for the shaft of the servo motor 6 to pass through the bearing surface 11, and the receiving groove 13 is used to receive the flange of the servo motor 6.

[0040] The first detection device 2 includes a first detection element 21 and a first indicator 22 movably connected along the height direction; the first detection element 21 can move along the height direction to abut against the end of the rotating shaft; the first indicator 22 is used to display the length parameter of the rotating shaft.

[0041] The second detection device 3 includes a second detection element 31 and a second indicator 32 that are movably connected along the height direction; the second detection element 31 can move along the height direction to abut against the end face of the flange; the second indicator 32 is used to display the thickness parameters of the flange.

[0042] In this embodiment, the motor testing equipment is used to detect the relevant dimensional parameters of the servo motor 6, including at least the shaft extension length and flange thickness of the servo motor 6. The shaft extension length refers to the length of the servo motor 6's shaft protruding from the front end of its housing. To achieve the testing purpose, the motor testing equipment in this embodiment includes a base 1 with a support portion 10 and a support surface 11 for placing the servo motor 6. During measurement of the servo motor 6, the position of the support surface 11 remains unchanged, and the position of the servo motor 6 in contact with it in the height direction also remains unchanged. During the measurement process, the operator only needs to place the servo motor 6 on the support surface 11 of the base 1.

[0043] Since the flange of the servo motor 6 protrudes from its motor housing, a recessed receiving groove 13 is provided on the bearing surface 11 to accommodate the flange when the servo motor 6 is placed on the bearing surface 11. The purpose of the receiving groove is to accommodate the flange. When the servo motor 6 is placed on the base, the front end of the motor housing of the servo motor 6 is in direct contact with the bearing surface 11, and the flange extends into the receiving groove 13, thereby preventing the flange from abutting against the bearing surface, so that the thickness of the flange can be detected.

[0044] Since the shaft of the servo motor 6 protrudes outward from the motor housing, a first mounting hole 12 is also provided through the bottom of the receiving groove 13. The first mounting hole 12 is provided through the bearing surface 11 along the height direction. Due to the existence of the first mounting hole 12, when the servo motor 6 is placed on the bearing surface 11, the shaft of the servo motor 6 can pass through the bottom of the receiving groove 13 and extend downward, and the front end face of the housing of the corresponding servo motor 6 can directly contact the bearing surface 11, thereby realizing the placement and bearing of the servo motor 6.

[0045] To measure the length of the servo motor 6 shaft, the motor testing device in this embodiment further includes a first testing device 2. This first testing device 2 includes a first testing element 21 and a first indicator 22, which are movably connected. That is, while maintaining this connection, the first testing element 21 can move relative to the first indicator 22 in the height direction without disrupting the connection between them. For the first testing device 2, the movement of the first testing element 21 in the height direction is equivalent to a telescoping or stretching change in that direction. Furthermore, the first indicator 22 can determine the degree to which the first testing element 21 is closer to or further away from the first indicator 22 based on its relative position to the first testing element 21, thus allowing for the measurement of the extension dimension of the end of the first testing element 21 furthest from the first indicator 22. Taking advantage of this feature, in this embodiment, the end of the first detection element 21 abuts against the end of the rotating shaft extending from the servo motor 6, which is placed on the bearing surface 11. Under the weight of the servo motor 6, the end of the first detection element 21 is pushed by the rotating shaft, thereby causing the first detection element 21 to move relative to the first indicator 22. The first indicator 22 can then indicate the real-time position of the first detection element 21. Since the real-time position of the first detection element 21 directly corresponds to the position of the end of the rotating shaft, the length of the motor shaft can be measured. It can be seen that during the entire measurement process, no manual measurement operation is required. The measurement can be automatically completed by the weight of the servo motor 6 simply by placing it on the bearing surface 11. This ensures measurement accuracy while improving measurement efficiency, thereby reducing the risk of defective products being shipped out. Moreover, the measurement method in this embodiment does not require moving the motor detection equipment during use. It only requires moving the servo motor 6 to place the servo motor 6 on the bearing surface 11. Therefore, it effectively reduces the need for frequent calibration of the motor detection equipment due to frequent movement / operation, and further improves the detection accuracy.

[0046] In addition, to measure the flange thickness simultaneously with the shaft length, the motor testing equipment in this embodiment further includes a second testing device 3, which comprises a second testing element 31 and a second indicator 32 movably connected along the height direction. The second testing element 31 can move along the height direction to abut against the end face of the flange; the second indicator 32 is used to display the flange thickness parameter. The setting position and measurement method of the second testing device 3 are similar to those of the first testing device 2, both being placed on the bearing surface 11 of the base 1. During the measurement process, the second testing element 31 of the second testing device 3 abuts against the end face of the flange, thereby achieving the measurement of the flange thickness parameter. Thus, in this embodiment, by simultaneously setting the first testing device 2 and the second testing device 3, the shaft length parameter and flange thickness parameter of the servo motor 6 can be measured directly and simultaneously when the servo motor 6 is placed on the base, effectively improving the testing efficiency of the servo motor.

[0047] Specifically, to measure the thickness parameters of the flange, a second mounting hole 14 can be provided at the bottom of the receiving groove 13, penetrating the bottom wall of the receiving groove 13 along the height direction; a second indicator 32 is fixedly disposed on the base 1, and a second detection element 31 is movably connected to the second indicator 32. The end of the second indicator 32 away from the second indicator 32 along the height direction abuts against the flange through the second mounting hole 14; the second indicator 32 is used to indicate the real-time position of the end of the second detection element 31 to determine the thickness parameters of the flange. The structure of the second detection device 3 is similar to that of the first detection device 2, consisting of a movably connected second indicator 32 and a second detection element 31. The second detection element 31 can also move relative to the second indicator 32 along the height direction, and the second indicator 32 is used to indicate the real-time position of the second detection element 31 to determine the size of the object measured by the second detection element 31. To measure the flange, in addition to the first mounting hole 12, the bottom of the receiving groove 13 also has a second mounting hole 14. The second mounting hole 14 also penetrates the bottom wall of the receiving groove 13, thus allowing the second detection element 31 to pass through. During measurement, the second detection element 31 extends from bottom to top into the receiving groove 13 through the second mounting hole 14, and after the servo motor 6 is placed, it abuts against the flange. The flange moves downwards against the end of the second detection element 31, thereby achieving the measurement of the flange thickness. Moreover, both the length of the rotating shaft and the thickness of the flange are measured by placing the servo motor 6 on the bearing surface 11 of the base 1, thus allowing for simultaneous measurement of both the length of the rotating shaft and the thickness of the flange, effectively improving measurement efficiency. Please refer to [reference needed]. Figure 4 As shown.

[0048] In some alternative embodiments, please refer to Figure 5To distinguish between the first mounting hole 12 used for measuring the length of the rotating shaft and the second mounting hole 14 used for measuring the flange thickness, the first mounting hole 12 can be located in the central area of ​​the receiving groove 13, while the second mounting hole 14 is eccentrically positioned on the bottom wall of the receiving groove 13. That is, the first mounting hole 12 is located in the center, and the second mounting hole 14 is eccentrically positioned, which corresponds to the position of the rotating shaft on the servo motor 6. Furthermore, with this structure, the flatness of the flange can be measured by rotating the servo motor 6, avoiding the problem of excessive deviation between local measurements and the actual situation.

[0049] In some optional embodiments, the first detection element 21 of the first detection device 2 measures the length of the motor shaft by moving up and down under the push of the motor shaft, while the second detection element 22 of the second detection device 3 measures the thickness of the flange by moving up and down under the push of the flange. To facilitate the measurement of different servo motors 6, in this embodiment, the first detection element 21 and the first indicator 22 are connected by a first elastic connector, which provides an elastic restoring force to cause the first detection element 21 to move upwards in the height direction. And / or, the second detection element 31 and the second indicator 32 are connected by a second elastic connector, which provides an elastic restoring force to cause the second detection element 311 to move upwards in the height direction. By connecting the first detection element 21 and the first indicator 22 with the first elastic connector, after one measurement is completed and the servo motor 6 is removed from the bearing surface 11, the position of the first detection element 21 will be restored, thus facilitating the measurement of the next servo motor 6. The same applies to the second elastic connector. In addition, by setting a first elastic connector to connect the first detection element 21 and the second detection element 31, the first detection element 21 can always maintain contact with the rotating shaft during the measurement process, thereby ensuring the accuracy of the measurement results. Specifically, the first detection device 2 and / or the second detection device 3 can each include any one of a dial indicator, a micrometer, or a ten-thousand-count indicator. Among them, dial indicators, micrometers, and ten-thousand-count indicators refer to general-purpose length measuring tools made using a precision rack and pinion mechanism, which are commonly used for measuring the length of shape and position errors and small displacements. The dial indicator amplifies the linear movement caused by the measured dimension through gear transmission, and then converts it into the rotation of the pointer on the scale, so that the user can read the size of the measured dimension. That is, it is a measuring instrument that uses gears to convert linear displacement into angular displacement. The difference between dial indicators, micrometers, and ten-thousand-count indicators lies in the measurement accuracy, with the measurement accuracy increasing sequentially from dial indicator to ten-thousand-count indicator. In the embodiment of this application, the first detection element 21 is equivalent to the measuring rod in the dial indicator, and the first indicator 22 is equivalent to the dial with pointer in the dial indicator.

[0050] The motor testing equipment in this embodiment is mainly used to test the dimensional reliability of the servo motor 6 to prevent defective products from being released. Therefore, to simplify the test results and allow operators to intuitively determine whether the tested servo motor 6 meets the requirements, the display area of ​​the dial can be divided into qualified and unqualified sector areas based on the preset qualified length parameters of the shaft and / or flange. During the measurement process, the pointer on the dial rotates. After the measurement result stabilizes, if the pointer is located in the qualified sector area, it indicates that the measured servo motor 6 is dimensionally qualified; otherwise, it is unqualified. With this structure, operators do not need to know the exact dimensional parameters of the shaft and flange to determine whether the servo motor meets the requirements, thereby improving testing efficiency while ensuring accuracy.

[0051] In some optional embodiments, to further secure the servo motor 6 and prevent relative movement between the servo motor 6 and the base 1, a protrusion 15 may be provided on the inner wall of the first mounting hole 12. The protrusion 15 matches the groove on the rotating shaft. The rotating shaft of the servo motor 6 generally has a pre-set groove for assembly. Therefore, in this embodiment, a protrusion 15 is provided on the inner wall of the first mounting hole 12. When the servo motor 6 is placed on the base 1, the rotating shaft is inserted along the first mounting hole 12, and the groove on the rotating shaft matches the protrusion 15. This restricts the rotation of the servo motor 6 relative to the base 1, thereby ensuring the stability of the detection data.

[0052] In some alternative embodiments, please refer to Figure 1 and Figure 6 In addition to detecting the shaft extension length of the servo motor 6 and the height of the flange, the motor testing equipment can also include a pneumatic gauge 4 and at least one pneumatic connector 5 connected to each other to detect the radial dimension parameters of the flange. The pneumatic connector 5 is disposed on the side wall of the receiving groove 13. The pneumatic gauge 4 is used to generate airflow, which is output to the space of the receiving groove 13 through the pneumatic connector 5 to detect the radial dimension parameters of the flange. That is, in this embodiment, the diameter of the flange is measured by means of airflow detection through the pneumatic gauge 4. The pneumatic gauge 4 is characterized by non-contact measurement, so it will not damage the tested product or the starting connector, and the measurement efficiency is very high. The measurement principle of the pneumatic gauge 4 is a comparative measurement method. Its measurement method is to convert the length signal into an airflow signal, and then indicate the value through a float in a transparent tube, which is a float-type pneumatic gauge 4; or convert the airflow signal into an electrical signal through a pneumatic-to-electric converter, and indicate the value by a light column composed of light-emitting tubes, which is called an electronic column-type pneumatic gauge 4. When the float / light column is in the qualified area, it indicates that the outer diameter of the flange meets the requirements. This detection method is accurate and efficient.

[0053] The pneumatic gauge 4 is a modular device that can be paired with different pneumatic connectors 5 to measure various parameters. In this embodiment, the pneumatic connector 5 can be an adjustable pneumatic quick-connect coupling, adaptable to flanges of different sizes. In some optional embodiments, two pneumatic connectors 5 may be included, arranged radially opposite each other along the receiving groove 13. The two pneumatic connectors 5 can output airflow to the flange from both radial sides, respectively, and then detect the flange's outer diameter based on the airflow.

[0054] This application provides a motor testing device. Since the servo motor 6 is directly placed on the bearing surface 11 of the base 1, the self-weight of the servo motor 6 is used to drive the testing device to measure the dimensions of the shaft and flange. The user does not need to manually operate the testing device, which improves the testing efficiency and ensures the accuracy of the testing results, thereby effectively reducing the risk of defective products flowing out.

[0055] Moreover, in this embodiment of the application, by setting two detection devices in the motor testing equipment, the axial dimensions of the motor shaft and the motor flange can be measured at one time, thereby further improving the testing efficiency.

[0056] Furthermore, in this embodiment, a pneumatic gauge 4, in conjunction with a pneumatic connector 5, is used to measure the radial dimension of the motor flange in a non-contact manner. This ensures measurement accuracy while reducing the risk of motor damage caused by contact measurement. Moreover, the measurement of the flange outer diameter by the pneumatic gauge 4 can be performed simultaneously with the measurements of the shaft length and flange thickness by the first and second detection devices, further improving the efficiency of servo motor dimension detection.

[0057] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
