[0002] At present, people often use test benches when testing new energy motors on the market. Test benches in the prior art generally fasten the motor, connect it to the test equipment through a coupling, and then test it. For example, a new energy vehicle motor test bench is disclosed in the patent with the authorization announcement number CN 220171086 U. The device can clamp the motor to be tested through the limit plates located on the two opposite sides of the motor to be tested, and can be installed for motors of different sizes; there is also an electric push rod that drives the test equipment to move in a lifting manner, which can meet the needs of docking with motors of different sizes. However, such motor test benches lack a mechanism to provide coaxiality standards, and cannot provide power travel control standards for power regulating equipment such as electric push rods. When used, they rely on manual judgment to determine the coaxial alignment between the test equipment and the motor to be tested, and the docking is not accurate enough. Utility Model Content

[0003] The technical solution of the utility model aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. It mainly provides a new energy motor test bench to solve the technical problems raised in the above background technology that there is a lack of a mechanism to provide coaxiality standards and cannot provide power stroke control standards for power regulating equipment such as electric push rods.

[0004] The technical solution adopted by the utility model to solve the above technical problems is:

[0005] A new energy motor test bench comprises a translation platform for placing motor products and a lifting platform with a test device installed, wherein the translation platform is installed on a base through a sliding movement mechanism, and the lifting platform is installed on the base through a lifting adjuster; a clamping mechanism for fixing the motor product is provided on the translation platform; a three-jaw chuck for sleeved on the output shaft of the motor product is provided between the translation platform and the lifting platform, the axis of the three-jaw chuck is parallel to the axis of the docking end of the test device and is located in the same vertical plane, and the three-jaw chuck is liftably connected to the base; an infrared transmitter is fixedly installed on the outer surface of the three-jaw chuck, and an infrared receiver located in the same vertical plane as the infrared transmitter is provided beside the docking end of the test device, and the distance between the infrared receiver and the axis of the docking end of the test device is equal to the distance between the infrared transmitter and the axis of the three-jaw chuck.

[0006] Furthermore, the clamping mechanism includes two clamping plates arranged opposite to each other and a bidirectional lead screw slider structure for driving the two clamping plates to move in opposite directions, and the center plane between the two clamping plates coincides with the vertical plane where the axis of the three-jaw chuck is located.

[0007] Furthermore, the translation platform is connected to two side plates and a top plate connected to the top of the side plates, and the clamping mechanism includes a screw rod vertically passing through the top plate and threadedly connected thereto, and a pressure plate connected to the bottom of the screw rod.

[0008] Furthermore, the three-jaw chuck is connected to the base via a telescopic rod.

[0009] Furthermore, the telescopic rod is slidably connected to the base, a slide rail for the telescopic rod to slide in translation is provided on the base, and a moving direction of the telescopic rod relative to the base is parallel to a moving direction of the translation platform.

[0010] Furthermore, the sliding movement mechanism includes support plates supported on both sides of the bottom of the translation platform and strip slide grooves opened on the base for the support plates to slide translationally, and the strip slide grooves extend from the side where the translation platform is located to the side where the lifting platform is located.

[0011] Furthermore, the sliding movement mechanism also includes a one-way screw slider structure for driving the translation stage to move, and the one-way screw is arranged parallel to the strip-shaped slide groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model is provided with a three-jaw chuck, and when used, the three-jaw chuck can be locked on the output shaft of the new energy motor, so that the three-jaw chuck is coaxial with the motor output shaft; then an infrared generator and an infrared receiver are respectively provided on the three-jaw chuck and the docking end of the test equipment. When used, the lifting platform is driven to move up and down by the lifting regulator until the infrared receiver receives the infrared light emitted by the infrared generator, and then the lifting regulator is stopped. At this time, the infrared receiver is aligned with the infrared transmitter, and because the distance between the infrared receiver and the axis of the docking end of the test equipment is equal to the distance between the infrared transmitter and the axis of the three-jaw chuck, the three-jaw chuck is coaxial with the docking end of the test equipment, that is, the output shaft of the new energy motor is coaxial with the docking end of the test equipment, so as to carry out docking of the new energy motor with the test equipment. Compared with the prior art, the utility model realizes the coaxiality of the three-jaw chuck with the motor output shaft and the coaxiality of the three-jaw chuck with the test equipment in turn through the arrangement of a three-jaw chuck, an infrared generator and an infrared receiver, effectively providing a coaxiality standard to ensure the precise docking of the new energy motor with the test equipment; and the infrared receiver is able to just receive the infrared light emitted by the infrared generator as the stroke control standard of electric drive equipment such as lifting regulators, which is easy to operate.

[0014] In the optimized solution of the utility model, the three-jaw chuck can translate with the new energy motor after being locked on its output shaft. During the movement, the infrared transmitter and the infrared receiver cooperate to monitor the coaxiality between the output shaft of the motor product and the docking end of the test equipment. Once the infrared receiver cannot receive the infrared light emitted by the infrared transmitter, it means that the motor product is not coaxial with the test equipment, and accurate docking cannot be achieved. The docking cannot continue, and the fault can be discovered in time.

When the infrared receiver 2 is aligned with the infrared transmitter 15, the three-jaw chuck 14 is also coaxial with the docking end of the test equipment 1.

[0033] A control processor (not shown in the figure) is provided in the test device 1, and the infrared transmitter 15, the infrared receiver 2 and the lifting regulator 12 are all in communication with the control processor.

[0034] In this embodiment, please refer to the attached Figure 1The clamping mechanism includes two clamping plates 5 arranged opposite to each other and a bidirectional lead screw slider structure 18 for driving the two clamping plates 5 to move in opposite directions. The bidirectional lead screw slider structure 18 specifically includes a bidirectional lead screw, two first sliders thread-fittingly mounted on the bidirectional lead screw, a guide rod passing through the first slider and parallel to the bidirectional lead screw, and a driving motor for driving the bidirectional lead screw to rotate. The two first sliders are fixedly connected to the two clamping plates 5 respectively; and the center plane between the two clamping plates 5 coincides with the vertical plane where the axis of the three-jaw chuck 14 is located, ensuring that the motor product is just aligned with the vertical plane where the axis of the three-jaw chuck 14 is located after being clamped by the clamping plates 5, so as to facilitate the installation of the three-jaw chuck 14 on the output shaft of the motor product.

[0035] In this embodiment, please refer to the attached Figure 3 and attached Figure 4 The three-jaw chuck 14 is connected to the base 10 through a telescopic rod 16, which enables the lifting and lowering movement of the three-jaw chuck 14, making it easy to align the three-jaw chuck 14 with the output shaft of the motor product.

The strip slide 11 extends from the side where the translation platform 6 is located to the side where the lifting platform 13 is located.

[0037] When in use, first place the new energy motor with test on the translation platform 6, drive the bidirectional lead screw slider structure 18, drive the clamping plate 5 to clamp the new energy motor, at this time, the new energy motor is just aligned with the vertical plane where the axis of the three-jaw chuck 14 is located;

[0038] Then manually hold the three-jaw chuck 14 and put it on the output shaft of the new energy motor, and turn the handle of the three-jaw chuck 14 so that the clamping jaws are synchronously pressed against the output shaft of the new energy motor, that is, the three-jaw chuck 14 is fixed on the output shaft of the new energy motor, and the three-jaw chuck 14 is coaxial with the output shaft of the new energy motor, and the telescopic rod 16 is telescopically changed accordingly;

[0039] Then start the infrared transmitter 15 to emit infrared light, and start the lifting regulator 12 to drive the lifting platform 13 to move up and down until the infrared receiver 2 receives the infrared light emitted by the infrared transmitter 15, and immediately stop driving the lifting regulator 12. At this time, the infrared receiver 2 is aligned with the infrared transmitter 15, and because the distance between the infrared receiver 2 and the axis of the docking end of the test equipment 1 is equal to the distance between the infrared transmitter 15 and the axis of the three-jaw chuck 14, the three-jaw chuck 14 is coaxial with the docking end of the test equipment 1, that is, the output shaft of the new energy motor is coaxial with the docking end of the test equipment 1;

[0040] Finally, the translation platform 6 is driven to move to the side where the lifting platform 13 is located, until it is docked with the testing equipment 1, and the testing work on the new energy motor can be carried out.

[0041] Embodiment 2: This embodiment differs from Embodiment 1 in that:

[0042] In this embodiment, please refer to the attached Figure 2 -Attached Figure 4 , the translation platform 6 is connected with two side plates 19 and a top plate 3 connected to the top of the side plates 19, the bidirectional lead screw slider structure 18 is installed on the top of the clamping plate 5 and is located between the two side plates 19, and the clamping mechanism also includes a screw rod 4 vertically passing through the top plate 3 and threadedly connected thereto, and a pressing plate 8 connected to the bottom of the screw rod 4. When used, after the motor product is clamped by the clamping plate 5, the screw rod 4 is rotated to drive the pressing plate 8 to move downward, which can press the motor product, thereby clamping the motor product in the vertical direction, achieving a more comprehensive clamping and fixing of the motor product, and ensuring the stability of the motor product.

The telescopic rod 16 can drive the three-jaw chuck 14 to translate along the slide rail 17, so that the three-jaw chuck 14 can be easily mounted on the output shaft of the motor product; after the three-jaw chuck 14 is mounted on the output shaft of the motor product, the translation platform 6 is driven to move to the side where the lifting platform 13 is located. Through the setting of the slide rail 17, the three-jaw chuck 14 can move synchronously with the motor product. During the movement, the infrared transmitter 15 and the infrared receiver 2 cooperate to monitor the coaxiality of the output shaft of the motor product and the docking end of the test equipment 1. Once the infrared receiver 2 cannot receive the infrared light emitted by the infrared transmitter 15, it means that the motor product is not coaxial with the test equipment 1 and cannot continue to dock.

[0044] In this embodiment, please refer to the attached Figure 2 -Attached Figure 3 The sliding mechanism also includes a one-way screw slider structure 9 for driving the translation platform 6 to move. The one-way screw slider structure 9 includes a one-way screw, a second slider that is thread-fitted on the one-way screw, and a driving motor that drives the one-way screw to rotate. The second slider is fixedly connected to the translation platform 6 through a connecting plate. The one-way screw is arranged parallel to the strip-shaped slide groove 11. The electric drive for the translation platform 6 is realized; the infrared transmitter 15 and the infrared receiver 2 can cooperate to detect the distance between the two, so that the moving distance of the translation platform 6 can be determined, and the travel control standard for the one-way screw slider structure 9 is provided.
