Detailed Implementation

[0019] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0020] In this embodiment of the utility model, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use.

[0021] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0022] The terms "parallel" and "perpendicular" do not mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be completely parallel, but that it can be slightly tilted.

[0023] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0024] Furthermore, terms like "roughly" and "basically" are used to indicate that the content does not require absolute precision, but rather allows for a certain degree of deviation. For example, "roughly equal" does not simply mean absolute equality; in actual production and operation, achieving absolute "equality" is difficult, and a certain degree of deviation is generally present. Therefore, besides absolute equality, "roughly equal to" also includes the aforementioned situation where a certain degree of deviation exists. Using this as an example, in other cases, unless otherwise specified, terms like "roughly" and "basically" have similar meanings.

[0025] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Example 1: like Figure 1-2 As shown, this embodiment provides a motor testing assembly, which includes: Support plate 11; The mounting mechanism 12 is mounted on the support plate 11 via the limiting engagement mechanism 13 and is used to mount the motor under test 100. The mounting mechanism 12 and the limiting engagement mechanism 13 are detachably connected. The mounting mechanism 12 is configured to be specifically used for a certain type of motor under test 100 and is adapted to the structure of that type of motor under test 100. The mounting mechanism 12 includes at least two types, and the mounting mechanism 12 can be replaced according to the type of motor under test 100. The clamping mechanism 14 is mounted on the bearing plate 11 and located on one side of the mounting mechanism 12. It is used to clamp the motor under test 100 to fix the motor under test 100 on the mounting mechanism 12. The testing mechanism 15 is mounted on the support plate 11 via the displacement adjustment mechanism 16 and is connected to the output end of the motor under test 100 via the transmission mechanism 17. The displacement adjustment mechanism 16 is used to adjust the displacement of the testing mechanism 15 in the axial direction perpendicular to the transmission mechanism 17.

[0028] Specifically, to enable a single component to test multiple different types of motors under test (DUTs) 100, this solution includes at least two types of mounting mechanisms 12. Each mounting mechanism 12 is configured specifically for a particular type of DUT 100 and is adapted to the structure of that type of DUT 100. Therefore, during testing, the mounting mechanism 12 can be replaced according to the type of DUT 100. The structure of the DUT 100 refers to its external shape, including features such as protrusions, grooves, and positioning holes. Therefore, different types of DUTs 100 may have the same external shape and dimensions, or they may differ. Therefore, in this embodiment, the mounting mechanism 12 is mounted on the support plate 11 via the limiting locking mechanism 13 to achieve a detachable connection. This allows for the selection of the appropriate mounting mechanism 12 based on the different types of motors under test 100, thus enabling the installation of the motors under test 100. Furthermore, to prevent vibrations during testing that could lead to inaccurate test results, a clamping mechanism 14 is provided to clamp the motors under test 100 and fix them onto the mounting mechanism 12. Secondly, since the type of motor under test 100 has changed, its structure will also change accordingly, and the position of the motor's output end may also differ. Therefore, a displacement adjustment mechanism 16 is provided to adjust the displacement of the testing mechanism 15 perpendicular to the axial direction of the transmission mechanism 17, ensuring that the testing mechanism 15 can be aligned and connected with the motor under test 100 via the transmission mechanism 17.

[0029] The mounting mechanism 12, the clamping mechanism 14, and the testing mechanism 15 are all located on the upper surface of the support plate 11, with the clamping mechanism 14 and the testing mechanism 15 located on opposite sides of the mounting mechanism 12. For ease of installation and disassembly, the testing mechanism 15 is connected to the transmission mechanism 17 via a coupling. The testing mechanism 15 includes a servo motor and a processor connected to each other. When testing the operating parameters of the motor under test 100, the motor under test 100 rotates, transmitting operating parameters such as speed to the servo motor via the transmission mechanism 17 for reading by the processor. During torque testing, the motor under test 100 and the servo motor simultaneously output torque, creating torque counteraction. Alternating high and low loads, such as 50%-150% of the rated load and forward / reverse loads, simulate actual operating condition fluctuations, achieving accurate testing under different operating conditions.

[0030] More specifically, the motor under test 100 can be a tracked rag gearbox motor, etc. The test includes: 1. Connecting the motor output shaft to the load, the load is displayed in the form of current, the load size is adjustable, and the load range is (0-3A); 2. Directly supplying the gearbox's rated operating voltage to an external voltage regulator to achieve forward rotation, and automatically switching to reverse rotation after forward rotation is completed, with adjustable forward and reverse rotation times. Through long-term, high-load operation, potential problems in the motor's materials, structure, or process are exposed (such as winding insulation aging, bearing wear, magnet demagnetization, etc.); the motor's tolerance under extreme conditions such as overload and frequent start-stop is tested to ensure it meets safety standards. In this solution, by adjusting the servo torque and rotation direction and reading the product's real-time data, and analyzing the test results, weak points (such as poorly heated stator structures and easily fatigued rotor components) are identified, guiding the selection of motor materials and optimization of heat dissipation solutions.

[0031] In one embodiment, since the mounting mechanism 12 is configured specifically for a particular type of motor under test 100 and is adapted to the structure of that type of motor under test 100, and since at least two types of mounting mechanisms 12 are included, the mounting mechanism 12 can be replaced according to the type of motor under test 100. Therefore, in order to ensure quick installation and disassembly between the mounting mechanism 12 and the limiting engagement mechanism 13 during use, and to ensure testing efficiency, each mounting mechanism 12 is first provided with at least two limiting engagement holes 120 in its vertical direction. The opening depth of the limiting engagement holes 120 is set to be adapted to the type of motor under test 100, and each limiting engagement hole 120 on the mounting mechanism 12 corresponding to the same motor under test 100 has the same... Regarding the opening depth, in practical applications: the opening depth of the limiting engagement hole 120 corresponding to different types of motors under test 100 may be the same or different, depending on the shape and structure of the motor under test. In addition, the limiting engagement mechanism 13 is configured to include: a limiting engagement plate 131, which is fixedly mounted on the support plate 11; at least two limiting engagement posts 132 that match the limiting engagement holes 120, which are vertically mounted on the limiting engagement plate 131. When the mounting mechanism 12 is mounted on the limiting engagement mechanism 13, the limiting engagement posts 132 are inserted into the corresponding limiting engagement holes 120 to fix the mounting mechanism 12 on the limiting engagement plate 131. When it is necessary to remove the mounting mechanism 12 from the limiting engagement posts 132, the mounting mechanism 12 can be directly pulled out. Since the height of the limiting engagement post 132 is fixed, opening limiting engagement holes 120 of different depths on the mounting mechanism 12 allows different mounting mechanisms 12 to be installed after the limiting engagement mechanism 13 at different heights. This results in a different overall height of the motor under test 100 after installation, ensuring that the output end of the motor under test 100 is at the same horizontal height as the transmission mechanism 17 on the testing mechanism 15, guaranteeing precise docking. The number of limiting engagement posts 132 and limiting engagement holes 120 is the same; preferably, providing two limiting engagement posts 132 and two limiting engagement holes 120 effectively ensures stability after installation.

[0032] In one implementation, such as Figure 1-3 As shown, the mounting mechanism 12 includes a mounting plate 121 for supporting the motor under test 100, and a slot 122 is provided on the mounting plate 121. The slot 122 matches the shape of the motor under test 100, so that after the motor under test 100 is installed, it is located in the slot 122. This method provides auxiliary positioning of the motor under test 100, thereby ensuring a more stable installation.

[0033] In another implementation, such as Figure 3As shown, the motor under test 100 has at least one positioning hole; the mounting plate 121 is also provided with at least one positioning rod 123. After the motor under test 100 is installed, the positioning rod 123 is inserted into the corresponding positioning hole on the motor under test 100. In this way, the motor under test 100 can be positioned to limit its movement, thereby cooperating with the slot 122 to further ensure that the motor under test 100 is installed more securely.

[0034] In one implementation, such as Figure 1-2 , Figure 4 As shown, the clamping mechanism 14 includes: a support frame 141; a clamping rod 142, which is telescopically mounted on the support frame 141; and a handle 143, which is rotatably mounted on the support frame 141. The handle 143 is connected to the clamping rod 142 via a connecting plate 144. By moving the handle 143, the extension and retraction state of the clamping rod 142 can be changed. In this way, the overall mechanism is simple. The extension and retraction state of the clamping rod 142 can be quickly adjusted by simply moving the handle 143, thereby enabling the rapid installation and removal of the motor under test 100. Furthermore, it can effectively ensure that the clamping rod 142 can clamp the motor under test 100, preventing the motor under test 100 from vibrating during the test.

[0035] In another implementation, such as Figure 1 As shown, when the clamping rod 142 is in the extended state, it will contact the motor under test 100 and cooperate with the mounting plate 121 to clamp the motor under test 100. Therefore, the end of the clamping rod 142 will apply a certain pressure to the motor under test 100. Therefore, soft materials such as rubber and plastic are provided at the end of the clamping rod 142 to increase the contact area between the end of the clamping rod 142 and the motor under test 100, so as to protect the motor under test 100 and avoid scratching or damaging the motor under test 100.

[0036] In one implementation, such as Figure 4 As shown, in order to ensure that the extension and retraction control of the tensioning rod 142 can be achieved when the handle 143 is turned, the connecting plate 144 is an arc-shaped connecting plate, and the two ends of the connecting plate 144 are respectively hinged to the handle 143 and the tensioning rod 142 to achieve a rotatable connection; and a receiving groove 1431 is provided on the handle 143. When the tensioning rod 142 is in the extended state, the connecting plate 144 is pushed by the extension of the tensioning rod 142, so that the end of the connecting plate 144 that is hinged to the handle 143 and a part thereof are confined within the receiving groove 1431, thereby realizing the extension and retraction of the tensioning rod 142.

[0037] In one embodiment, since the mounting mechanism 12 is configured specifically for a particular type of motor under test 100 and is adapted to the structure of that type of motor under test 100, and since at least two types of mounting mechanisms 12 are included, the mounting mechanism 12 can be replaced according to the type of motor under test 100. Therefore, a mounting mechanism 12 with a corresponding shape and structure matching the type of motor under test 100 can be selected and installed on the limiting engagement mechanism 13. At this time, since the type of motor under test 100 has changed, its structure will also change accordingly, and the position of the motor under test 100 on the mounting mechanism 12 may also change. To accommodate different types of motors under test 100 and achieve tight clamping and fixing of the motors under test 100, the clamping rod 142 is configured to include: a mounting rod 1421, one end of which is hollow and has an internal thread; and an adjusting rod 1422, one end of which has an external thread. The adjusting rod 1422 is rotatably and detachably connected to the mounting rod 1421 via the thread. The mounting rod 1421 can be replaced according to the type of motor under test 100, and the extension and contact position of the adjusting rod 1422 with the motor under test 100 can be adjusted by rotating the adjusting rod 1422. More specifically, depending on the type of motor under test 100, the adjusting rod 1422 can be configured as a straight rod, a Y-shaped rod, or a Z-shaped rod, etc.

[0038] In one embodiment, the transmission mechanism 17 is configured to include: a mounting cylinder 171 and a telescopic component 172 disposed within the mounting cylinder 171. The mounting cylinder 171 and the telescopic component 172 may be cylindrical or rectangular. The connecting end of the mounting cylinder 171 is connected to the test mechanism 15, and the connecting end of the telescopic component 172 is located outside the mounting cylinder 171 and connected to the output end of the motor under test 100. This allows the telescopic component 172 to extend or retract relative to the mounting cylinder 171, thereby achieving a soft connection between the test mechanism and the motor under test, effectively protecting the motor under test, and also enabling the telescopic component 172 to quickly connect and disconnect from the motor under test 100, thereby increasing test efficiency.

[0039] In one implementation, such as Figure 1-2 , Figure 5 As shown, the transmission mechanism 17 also includes a limiting mechanism 173, which is disposed on the telescopic component 172 and contacts the mounting cylinder 171, for limiting the telescopic component 172's extension and retraction relative to the mounting cylinder 171. Specifically, since the telescopic component 172 continuously generates an outward force, a limiting mechanism 173 is provided on the telescopic component 172 to prevent the telescopic component 172 from detaching from the mounting cylinder 171 and to prevent the telescopic component 172 from applying excessive thrust to the motor 100 under test.

[0040] In one implementation, such as Figure 1-2 , Figure 5As shown, the telescopic assembly 172 includes an elastic mechanism 1721 and a telescopic rod 1722. The elastic mechanism 1721 is disposed inside the mounting cylinder 171, and one end of the telescopic rod 1722 is located inside the mounting cylinder 171 and connected to the elastic mechanism 1721. Specifically, the elastic mechanism 1721 is disposed inside the mounting cylinder 171, and one end of the telescopic assembly 172 is fixedly connected to the mounting cylinder 171, while the other end is in contact with or connected to the elastic mechanism 1721. This allows the elastic mechanism 1721 to continuously apply a pushing force to the telescopic rod 1722, thereby ensuring a stable connection between the connection end of the telescopic rod 1722 and the output end of the motor 100 under test. More specifically, the elastic mechanism 1721 can be configured as a spring in a compressed state, and a stepped surface can be provided at the end of the telescopic rod 1722 located inside the mounting cylinder 171, such that the end of the telescopic rod 1722 is located inside the spring, and the end of the spring abuts against the stepped surface of the telescopic rod 1722, thereby ensuring the stability of the contact area.

[0041] In one implementation, such as Figure 5 As shown, the elastic mechanism 1721 continuously provides outward elastic force to the telescopic rod 1722, causing the telescopic rod 1722 to withstand the force of pushing out the mounting cylinder 171. To ensure that the telescopic rod 1722 does not detach from the mounting cylinder 171 and to avoid excessive pressure on the motor under test by the telescopic rod 1722 during testing, a limiting hole 1711 is provided on the mounting cylinder 171; a mounting hole 1723 is provided on the telescopic rod 1722; and the limiting mechanism 173 is a pin, with one end of the pin passing through the limiting hole 1711 and set on the mounting hole 1723. Preferably, to prevent the pin from detaching from the mounting hole 1723, the end of the pin is provided with an external thread, and an internal thread is provided in the mounting hole 1723. The connection is stable through threaded connection. Alternatively, a groove is provided at the end of the pin, and after the end of the pin passes through the mounting hole 1723, a retaining spring is provided to engage with the groove for limiting, thereby fixing the pin on the telescopic rod 1722. In addition, for different models of motors under test 100, adaptation can be achieved by replacing the matching telescopic rod 1722. When replacing the telescopic component 172, pull the pin out of the mounting hole 1723 of the telescopic rod 1722. At this time, the telescopic rod 1722 can be removed from the mounting cylinder 171. After replacing the matching telescopic rod 1722, insert the end of the telescopic rod 1722 into the mounting cylinder 171 and make contact with the elastic mechanism 1721. Then, insert the pin from the limiting hole 1711 into the mounting hole 1723 of the telescopic rod 1722 to limit the telescopic rod 1722 and complete the replacement of the telescopic rod 1722. This enables the testing of motors under test 100 of different models and sizes.

[0042] In one embodiment, the connecting end of the telescopic rod 1722 is interlocked with the output end of the motor under test 100. This interlocking method enables rapid connection and disassembly of the telescopic assembly 172 and the motor under test 100, thereby improving testing results. Specifically, the connecting end of the telescopic rod 1722 is configured as a rectangular rod, and correspondingly, a rectangular groove matching the rectangular rod is provided at the output end of the motor under test 100 (or a rectangular groove is provided at the connecting end of the telescopic rod 1722, and correspondingly, the output end of the motor under test 100 is configured as a rectangular rod matching the rectangular groove). Through the interlocking of the rectangular rod and the rectangular groove, both rapid installation and disassembly, as well as torque transmission, are achieved (the rectangular rod and rectangular groove can also adopt rhomboid, elliptical, or other adaptable structures). When connecting the telescopic rod 1722 to the motor under test 100, first retract the extension length of the telescopic rod 1722 so that the rectangular rod aligns with the rectangular groove. Then, extend the telescopic rod 1722, allowing the rectangular rod to insert into the rectangular groove and engage with it, thus quickly connecting the telescopic rod 1722 and the motor under test 100. When disassembling the telescopic rod 1722 from the motor under test 100, simply retract the extension length of the telescopic rod 1722 to disengage it from the motor under test 100, thus quickly separating the telescopic rod 1722 from the motor under test 100.

[0043] In one implementation, such as Figure 1-2 As shown, the motor testing assembly also includes a support and limiting plate 18, which has a receiving hole 181. A bearing 182 is installed inside the receiving hole 181. The transmission mechanism 17 passes through the receiving hole 181 and connects to or merely contacts the inner ring of the bearing 182. By supporting and limiting the transmission mechanism 17 through the bearing 182, vibrations of the transmission mechanism 17 during rotation can be reduced, ensuring coaxiality and thus guaranteeing the accuracy of the test results.

[0044] In another implementation, such as Figure 1-2 As shown, the testing mechanism 15 is mounted on the support limiting plate 18 and then installed on the bearing plate 11. In this case, the support limiting plate 18 adopts a U-shaped structure, including a first vertical plate and a second vertical plate, with a certain space between the first and second vertical plates. The testing mechanism 15 is fixed to the first vertical plate, and a receiving hole 181 and a mounting bearing 182 are provided on the second vertical plate. Furthermore, the support limiting plate 18 adopts an integral molding structure to ensure the overall structural strength.

[0045] In one implementation, such as Figure 1-2As shown, since the mounting mechanism 12 is configured specifically for a certain type of motor under test 100, and is adapted to the structure of that type of motor under test 100, and the mounting mechanism 12 includes at least two types, the mounting mechanism 12 can be replaced according to the type of motor under test 100. Therefore, the mounting mechanism 12 with the corresponding shape and structure can be selected according to the type of motor under test 100 and installed on the limiting engagement mechanism 13. At this time, since the type of motor under test 100 has changed, its structure will also change accordingly, and the position of the output end of the corresponding motor may also be different. Therefore, in order to ensure that the test mechanism 15 can be aligned and connected with the motor under test 100 through the transmission mechanism 17, a displacement adjustment mechanism 16 is set to adjust the displacement of the test mechanism 15 in the axial direction perpendicular to the transmission mechanism 17. Specifically, the displacement adjustment mechanism 16 includes: at least one transverse slide rail 161, arranged on the support plate 11 in a direction perpendicular to the axial direction of the transmission mechanism 17; a transverse slider 162, arranged on the transverse slide rail 161, which can slide; and a testing mechanism 15, arranged on the upper surface of the transverse slider 162. The position of the testing mechanism 15 is adjusted by sliding the transverse slider 162. In addition, to prevent the testing mechanism 15 from vibrating with the motor under test 100 during the test, which would affect the test results, a tightening screw 163 is provided on the transverse slider 162 to fix the transverse slider 162 to the transverse slide rail 161. Before the test begins, the transverse slider 162 is moved to the corresponding position, and the tightening screw 163 is tightened to limit the displacement of the transverse slider 162 and achieve fixation. More specifically, the tightening screw 163 can be set on the upper end face of the transverse slider 162, so that it can contact the bearing plate 11 in the tightened state to achieve fixed positioning; the tightening screw 163 can be set on the side of the transverse slider 162, so that it can contact the transverse slide rail 161 in the tightened state to achieve fixed positioning.

[0046] like Figure 8-9 As shown, this embodiment also provides a motor testing device, which includes: Mounting frame 2 has at least one mounting plane 21; Multiple of the aforementioned motor test components 1 are mounted on the mounting plane 21.

[0047] Specifically, in this embodiment, a horizontal plate is provided at the top of the mounting frame 2, thereby forming a mounting plane 21. Each mounting plane 21 can accommodate multiple motor test components 1, such as 10 or 20 motor test components 1, thereby enabling simultaneous testing of multiple motors 100 under test and improving testing efficiency. Furthermore, several threaded holes are made at corresponding positions on the mounting plane 21 and the motor test components 1, and the motor test components 1 are mounted on the mounting plane 21 using screws passing through the corresponding threaded holes. The motor testing equipment uses materials such as bakelite, AL6061, PTFE, and SUS304, ensuring structural stability while effectively guaranteeing the safety of operators.

[0048] In one implementation, such as Figure 8-9 As shown, the mounting frame 2 is a rectangular frame, with protective side plates 22 on each side, forming an internal accommodating space within the mounting frame 2. At least one protective side plate 22 on the mounting frame 2 is openable and closable. The motor testing equipment also includes a power distribution cabinet 3, located within the internal accommodating space of the mounting frame 2, used to supply power to the motor under test 100 and the testing mechanism 15. The protective side plates 22 form the internal accommodating space, and placing the power distribution cabinet 3 within this space effectively improves safety performance.

[0049] In one implementation, such as Figure 8-9 As shown, since the power distribution cabinet 3 is located within the internal storage space, it generates heat during the process of supplying power to the motor under test 100 and the testing mechanism 15. Therefore, to ensure the normal operation of the equipment and improve safety, a cooling mechanism 4 is installed within the mounting frame 2 to reduce the temperature in the internal storage space. Preferably, the cooling mechanism 4 is configured with multiple fans, and ventilation openings are provided on at least one protective side plate 22. The fans cover the ventilation openings, and air is blown outward through the openings to remove heat from the internal storage space, thereby achieving a cooling effect.

[0050] In one implementation, such as Figure 8-9As shown, the motor testing equipment also includes: a moving mechanism 5, located at the bottom of the mounting frame 2, for moving the motor testing equipment; and a support and leveling mechanism 6, located at the bottom of the mounting frame 2, for supporting the motor testing equipment and adjusting its levelness during testing. Specifically, taking a rectangular frame structure as an example, the moving mechanism includes four moving rollers, symmetrically arranged at the bottom of the mounting frame 2. During the movement of the motor testing equipment, the rollers facilitate quick and easy movement, reducing manpower. Additionally, the support and leveling mechanism 6 consists of four support pads, symmetrically arranged at the bottom of the mounting frame 2. When the motor testing equipment moves to the designated position, the four support pads support the equipment, preventing displacement during testing and ensuring the test results. Furthermore, for ease of movement and leveling, each support pad is threadedly connected to the mounting frame 2 with bolts. Rotating the corresponding support pad allows it to rotate, adjusting its extension distance relative to the mounting frame 2, thereby adjusting the levelness of the mounting frame 2 (motor testing equipment) and ensuring that all motor testing components 1 on the mounting plane 21 are level.

[0051] In one embodiment, the motor testing equipment further includes: A control module (not shown) is connected to each motor test component 1 and is used to detect the test parameters of the motor test component 1. The human-machine interaction module 7 is connected to each motor test component 1 and is used to display and adjust the test parameters of the motor test component 1. In addition, the power distribution cabinet 3 can be controlled by an industrial control computer to realize power supply and power cut-off during the test process.

[0053] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the various possible combinations will not be described separately in this embodiment.

[0054] Furthermore, various different implementation methods of this utility model can be arbitrarily combined, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
