Description

Technical Field

[0002] As a key component of an automotive power system, the performance of an automotive starting motor directly affects the starting efficiency and reliability of a vehicle. During actual use of a vehicle, the automotive starting motor needs to operate under various complex environmental conditions, such as harsh environments like high temperature and low temperature. High and low temperature environmental factors can have a significant impact on the performance and service life of an automotive starting motor. Therefore, during the production of an automotive starting motor, it is crucial to conduct high and low temperature environmental adaptability tests on the automotive starting motor. When testing the high and low temperature environmental adaptability of an automotive starting motor, a high and low temperature testing device is used. For example, a high and low temperature test chamber is one of them.

[0003] Although existing high and low temperature test chambers can achieve high and low temperature environmental testing of automotive starting motors, during the testing process, they can only complete the testing of the start and stop functions of automotive starting motors under high and low temperature conditions, and it is difficult to collect dynamic data such as torque and rotational speed of automotive starting motors in high and low temperature environments in real time. And these parameters are key indicators for evaluating the power output characteristics of automotive starting motors in extreme temperature environments. The lack of data makes it difficult for the test results to comprehensively reflect the actual performance of automotive starting motors, thereby reducing the practicality of high and low temperature test chambers when testing automotive starting motors. In addition, for existing specialized equipment for testing the torque of automotive starting motors, when positioning the automotive starting motor, the position needs to be adjusted repeatedly, which not only increases the clamping time but also reduces the batch testing efficiency due to the cumbersome operation process, thus being unfavorable for the testing work of a large number of automotive starting motors.

A spring is sleeved on the outside of each guiding slide bar 605 between the sliding block 601 and the guiding plate 606. The front ends of the two guiding slide bars 605 are fixedly connected to a handle 607; through the setting of the synchronous pulling assembly 6, when it is necessary to remove the automotive starting motor 3 from the inside of the high and low temperature test chamber 1, only need to hold the hand on the handle 607 and the auxiliary handle 608, and then firmly grip, then the two positioning insertion posts 206 can be quickly pulled out from the positioning insertion holes 105, and at this time, the quick loading and unloading seat 2 and the automotive starting motor 3 can be moved forward for disassembly, thereby improving the convenience of removing the automotive starting motor 3 from the inside of the high and low temperature test chamber 1.

[0029] The synchronous pulling assembly 6 further includes an auxiliary handle 608 which is fixedly connected to the front end face of the quick loading and unloading seat 2, and the auxiliary handle 608 is located outside the handle 607. Through the arrangement of the auxiliary handle 608, the convenience of moving the handle 607 forward is improved.

[0030] When the quick loading and unloading seat 2 and the C-shaped mounting frame 102 are in the installed state, the two positioning plug posts 206 are respectively inserted into the positioning jacks 105 opened on the two positioning plugging plates 104. At this time, the driving gear 301 meshes with the driven gear 406, and at this time, the rectangular locking block 602 is located between the two sliding plates 205.

During the installation process, the hand can be held on the handle 607 and the auxiliary handle 608, and then firmly grasped. The handle 607 drives the two guiding slide rods 605, the sliding block 601, the rectangular locking block 602, and the front ends of the two pull ropes 603 to move forward. Then, under the combined action of the two pull ropes 603 and the pulley 604, the two sliding plates 205 and the two positioning pins 206 are driven to move simultaneously in the opposite directions. Then, continue to move the quick loading and unloading seat 2 backward. When the quick loading and unloading seat 2 moves backward to the limit position, release the handle 607. At this time, the two sliding plates 205 drive the two positioning pins 206 to move simultaneously in the opposite directions under the elastic force of the spring outside the guiding rod 204, so that the two positioning pins 206 are inserted into the positioning holes 105 opened on the two positioning plugging plates 104. And at this time, the driving gear 301 is engaged with the driven gear 406, thus quickly completing the installation and positioning work of the automotive starting motor 3. Moreover, during the installation and positioning process, there is no need to repeatedly adjust the position of the automotive starting motor 3, which not only saves the clamping time but also effectively improves the efficiency of the automotive starting motor 3 during batch testing, thus facilitating the testing work of a large number of automotive starting motors 3. Then, the sliding block 601 drives the rectangular locking block 602 to move backward under the elastic force of the spring outside the guiding slide rod 605. At this time, the rectangular locking block 602 is located between the two sliding plates 205 and locks and limits the two sliding plates 205, thus effectively improving the firmness of the positioning pin 206 during plugging and positioning and avoiding the loosening of the positioning pin 206 during the test, thereby improving the reliability of the present testing device during the test.

Then, drive the rotation of the rotating shafts of the driving gear 301, driven gear 406, transmission shaft 401, torque sensor 403 and the load device 404 through the automotive starting motor 3. At this time, the load device 404 exerts a load on the automotive starting motor 3 to simulate the load that the automotive starting motor 3 has to bear during actual use. Then, the torque sensor 403 monitors the operating performance parameters such as the torque and speed of the automotive starting motor 3 in real time, and the display screen 405 displays the dynamic data of the torque and speed monitored by the torque sensor 403, so that the actual performance of the automotive starting motor 3 can be tested more comprehensively, and thus the practicability of this test device when testing the automotive starting motor 3 is greatly improved.
