Technical Field

[0001] This utility model relates to the field of motor testing technology, specifically to a motor testing device and a motor testing equipment. Background Technology

[0002] As a core power component in modern industry, the performance, reliability, and lifespan of electric motors directly affect the operating status of the entire equipment or system. Therefore, comprehensive and efficient performance testing of electric motors before they leave the factory or after maintenance is a crucial step. This testing typically includes measuring parameters such as controlled forward and reverse rotation, time, and controlled load fatigue aging tests.

[0003] In existing technologies, conventional motor devices, in pursuit of high precision and multifunctionality, typically employ complex mechanical structures and precise mounting and fixing mechanisms. This results in a relatively complex overall structure, cumbersome operating procedures during testing, and an inability to achieve rapid installation and disassembly for testing, leading to low testing efficiency. Furthermore, the rigid connection between the testing device and the motor under test poses a risk of generating radial or axial forces, causing distorted test data or even damaging the motor.

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] like Figure 1-2 As shown, this embodiment provides a motor testing device, which includes: Support plate 11; The mounting mechanism 12 is mounted on the support plate 11 and is used to mount the motor 100 to be tested. The clamping mechanism 13 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 14 is mounted on the support plate 11 and connected to the output end of the motor under test 100 via the transmission mechanism 15. The testing mechanism 14 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, and the transmission mechanism 15 transmits the operating parameters such as the speed to the servo motor, which is then read by the processor. When performing torque testing, the motor under test 100 and the servo motor output torque simultaneously to form torque counteraction, and high and low loads such as 50%-150% of the rated load and forward and reverse loads are applied alternately to simulate the fluctuations of actual working conditions and achieve accurate testing under different working conditions. The transmission mechanism 15 includes a mounting cylinder 151 and a telescopic component 152 disposed inside the mounting cylinder 151. The connecting end of the mounting cylinder 151 is connected to the testing mechanism 14, and the connecting end of the telescopic component 152 is located outside the mounting cylinder 151 and is connected to the output end of the motor 100 under test.

[0028] Specifically, in this embodiment, the mounting mechanism 12, the clamping mechanism 13, and the testing mechanism 14 are all disposed on the upper surface of the support plate 11, and the mounting mechanism 12, the clamping mechanism 13, and the testing mechanism 14 can be arranged in a straight line, that is, the clamping mechanism 13 and the testing mechanism 14 are respectively located on both sides of the mounting mechanism 12. In order to facilitate installation and disassembly, the testing mechanism 14 is connected to the connecting end of the mounting cylinder 151 through a coupling. In addition, the transmission mechanism 15 is configured to include: a mounting cylinder 151 and a telescopic component 152 disposed within the mounting cylinder 151. The mounting cylinder 151 and the telescopic component 152 can be cylindrical or rectangular. The connecting end of the mounting cylinder 151 is connected to the test mechanism 14, and the connecting end of the telescopic component 152 is located outside the mounting cylinder 151 and connected to the output end of the motor under test 100. This allows the telescopic component 152 to extend or retract relative to the mounting cylinder 151, thereby achieving a soft connection between the test mechanism and the motor under test, effectively protecting the motor under test, and also enabling rapid connection and disconnection between the telescopic component 152 and the motor under test 100, thus increasing test efficiency. The motor under test 100 can be a tracked rag gearbox motor, etc. The test content includes: 1. The motor output shaft is connected to a load, the load is displayed in the form of current, the load size is adjustable, and the load range is (0-3A); 2. An external voltage regulator directly supplies the rated working voltage of the gearbox to achieve forward rotation. After forward rotation is completed, it automatically switches to reverse rotation, and the forward and reverse rotation time is adjustable. By operating the motor under prolonged high loads, potential problems in its materials, structure, or manufacturing processes are exposed (such as winding insulation aging, bearing wear, and magnet demagnetization). The motor's tolerance to extreme conditions such as overload and frequent start-stop cycles is tested to ensure it meets safety standards. This solution involves adjusting servo torque and rotation direction, reading real-time product data, and analyzing test results to identify weaknesses (such as poorly heated stator structures or easily fatigued rotor components) to guide motor material selection and optimize heat dissipation solutions.

[0029] 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.

[0030] In one implementation, such as Figure 3 As 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.

[0031] In one implementation, such as Figure 1-2 , Figure 4 As shown, the clamping mechanism 13 includes: a support frame 131; a clamping rod 132, which is telescopically mounted on the support frame 131; and a handle 133, which is rotatably mounted on the support frame 131. The handle 133 is connected to the clamping rod 132 via a connecting plate 134. By moving the handle 133, the extension and retraction state of the clamping rod 132 can be changed. In this way, the overall mechanism is simple. The extension and retraction state of the clamping rod 132 can be quickly adjusted by simply moving the handle 133, thereby enabling the rapid installation and removal of the motor under test 100. Furthermore, it can effectively ensure that the clamping rod 132 can clamp the motor under test 100, preventing the motor under test 100 from vibrating during the test.

[0032] In another implementation, such as Figure 1 As shown, when the clamping rod 132 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 132 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 132 to increase the contact area between the end of the clamping rod 132 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.

[0033] In one implementation, such as Figure 4As shown, in order to ensure that the extension and retraction control of the tensioning rod 132 can be achieved when the handle 133 is turned, the connecting plate 134 is an arc-shaped connecting plate, and the two ends of the connecting plate 134 are respectively hinged to the handle 133 and the tensioning rod 132 to achieve a rotatable connection; and a receiving groove 1331 is provided on the handle 133. When the tensioning rod 132 is in the extended state, the connecting plate 134 is pushed by the extension of the tensioning rod 132, so that the end of the connecting plate 134 that is hinged to the handle 133 and a part thereof are confined in the receiving groove 1331, thereby realizing the extension and retraction of the tensioning rod 132.

[0034] In one implementation, such as Figure 1-2 As shown, the motor testing device also includes a support and limiting plate 16, on which a receiving hole 161 is provided. A bearing 162 is installed inside the receiving hole 161. The transmission mechanism 15 passes through the receiving hole 161 and connects to or merely contacts the inner ring of the bearing 162. By supporting and limiting the transmission mechanism 15 through the bearing 162, vibrations of the transmission mechanism 15 during rotation can be reduced, ensuring coaxiality and thus guaranteeing the accuracy of the test results.

[0035] In another implementation, such as Figure 1-2 As shown, the testing mechanism 14 is mounted on the support limiting plate 16 and then installed on the bearing plate 11. In this case, the support limiting plate 16 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 14 is fixed to the first vertical plate, and a receiving hole 161 and a mounting bearing 162 are provided on the second vertical plate. Furthermore, the support limiting plate 16 adopts an integral molding structure to ensure the overall structural strength.

[0036] In one implementation, such as Figure 1-2 , Figure 5 As shown, the transmission mechanism also includes a limiting mechanism 153, which is disposed on the telescopic component 152 and contacts the mounting cylinder 151, for limiting the telescopic component 152's extension and retraction relative to the mounting cylinder 151. Specifically, since the telescopic component 152 continuously generates an outward force, a limiting mechanism 153 is provided on the telescopic component 152 to prevent it from detaching from the mounting cylinder 151 and to prevent it from applying excessive thrust to the motor under test.

[0037] In one implementation, such as Figure 1-2 , Figure 5As shown, the telescopic assembly 152 includes an elastic mechanism 1521 and a telescopic rod 1522. The elastic mechanism 1521 is disposed inside the mounting cylinder 151, and one end of the telescopic rod 1522 is located inside the mounting cylinder 151 and connected to the elastic mechanism 1521. Specifically, the elastic mechanism 1521 is disposed inside the mounting cylinder 151, and one end of the telescopic assembly 152 is fixedly connected to the mounting cylinder 151, while the other end is in contact with or connected to the elastic mechanism 1521. This allows the elastic mechanism 1521 to continuously apply a pushing force to the telescopic rod 1522, thereby ensuring a stable connection between the connecting end of the telescopic rod 1522 and the output end of the motor 100 under test. More specifically, the elastic mechanism 1521 can be configured as a spring in a compressed state, and a stepped surface can be provided at the end of the telescopic rod 1522 located inside the mounting cylinder 151, such that the end of the telescopic rod 1522 is located inside the spring, and the end of the spring abuts against the stepped surface of the telescopic rod 1522, thereby ensuring the stability of the contact area.

[0038] In one implementation, such as Figure 5 As shown, the elastic mechanism 1521 continuously provides outward elastic force to the telescopic rod 1522, causing the telescopic rod 1522 to withstand the force of pushing out the mounting cylinder 151. To ensure that the telescopic rod 1522 does not detach from the mounting cylinder 151 and to avoid excessive pressure on the motor under test by the telescopic rod 1522 during testing, a limiting hole 1511 is provided on the mounting cylinder 151; a mounting hole 1523 is provided on the telescopic rod 1522; and the limiting mechanism 153 is a pin, with one end of the pin passing through the limiting hole 1511 and set on the mounting hole 1523. Preferably, to prevent the pin from detaching from the mounting hole 1523, the end of the pin is provided with an external thread, and an internal thread is provided in the mounting hole 1523. 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 1523, a retaining spring is provided to engage with the groove for limiting, thereby fixing the pin on the telescopic rod 1522. In addition, for different models of motors under test 100, adaptation can be achieved by replacing the matching telescopic rod 1522. When replacing the telescopic component 152, pull the pin out of the mounting hole 1523 of the telescopic rod 1522. At this time, the telescopic rod 1522 can be removed from the mounting cylinder 151. After replacing the matching telescopic rod 1522, insert the end of the telescopic rod 1522 into the mounting cylinder 151 and make contact with the elastic mechanism 1521. Then, insert the pin from the limiting hole 1511 into the mounting hole 1523 of the telescopic rod 1522 to limit the telescopic rod 1522 and complete the replacement of the telescopic rod 1522. This enables the testing of motors under test 100 of different models and sizes.

[0039] In one embodiment, the connecting end of the telescopic rod 1522 is interlocked with the output end of the motor under test 100. This interlocking method enables rapid connection and disassembly of the telescopic component 152 and the motor under test 100, thereby improving testing results. Specifically, the connecting end of the telescopic rod 1522 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 1522, 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 1522 to the motor under test 100, first retract the extension length of the telescopic rod 1522 so that the rectangular rod aligns with the rectangular groove. Then, extend the telescopic rod 1522, allowing the rectangular rod to insert into the rectangular groove and engage with it, thus quickly connecting the telescopic rod 1522 and the motor under test 100. When disassembling the telescopic rod 1522 from the motor under test 100, simply retract the extension length of the telescopic rod 1522 to disengage it from the motor under test 100, thus quickly separating the telescopic rod 1522 from the motor under test 100.

[0040] like Figure 6-7 As shown, this embodiment also provides a motor testing device, which includes: Mounting frame 2 has at least one mounting plane 21; Multiple motor testing devices 1 are mounted on the mounting plane 21.

[0041] 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 testing devices 1, such as 10 or 20 motor testing devices 1, thereby enabling simultaneous testing of multiple motors 100 under test and improving testing efficiency. Furthermore, several threaded holes are provided at corresponding positions on the mounting plane 21 and the motor testing devices 1, and the motor testing devices 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.

[0042] In one implementation, such as Figure 6-7As 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 14. The protective side plates 22 form the internal accommodating space, and placing the power distribution cabinet 3 within this space effectively improves safety performance.

[0043] In one implementation, such as Figure 6-7 As shown, since the power distribution cabinet 3 is located within the internal enclosure, it generates heat during the process of supplying power to the motor under test 100 and the testing mechanism 14. 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 enclosure. Preferably, the cooling mechanism 4 consists of 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 enclosure, thus achieving a cooling effect.

[0044] In one implementation, such as Figure 6-7 As 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 devices 1 on the mounting plane 21 are level.

[0045] In one embodiment, the motor testing equipment further includes: A control module (not shown) is connected to each motor testing device 1 and is used to detect the test parameters of the motor testing device 1. The human-machine interaction module 7 is connected to each motor testing device 1 and is used to display and adjust the test parameters of the motor testing device 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.

However, the present utility model is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present utility model, various simple modifications can be made to the technical solutions of the present utility model, and these simple modifications all fall within the protection scope of the present utility model.

[0047] 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.

[0048] 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.
