Description

Technical Field

[0001] The utility model relates to the field of actuator detection, in particular to an off-line detection device for automotive actuators. Background Art

[0002] Automotive actuators are mainly used in automotive aerodynamic management, thermal management or their optimization, and can be installed on assemblies such as automotive intake grilles (including internal and external grilles), spoiler racks or cooling water valves. An actuator mainly refers to a gear train transmission device based on motor control. The micro motor drives the gear train to decelerate, and then drives the output gear train to rotate, outputting a certain rotational speed and torque as required to adjust the rotation of the air-conditioning air damper or the opening and closing of the cooling water valve.

[0003] At present, with the increasing popularity of automotive driving and control automation and intelligence, the quality and safety management of automotive electronic products are becoming more and more strict, and the standards are getting higher and higher. Automotive actuators are one of the key components among many automotive parts, and their quality affects the normal operation of the vehicle and the user experience.

[0004] Currently, after the production of automotive actuators, a qualification inspection will be carried out. One of the main current detection methods is to plug in the electrical plug of the connector to make the actuator enter the working state, and observe whether it rotates with the naked eye. The advantage of observing with the naked eye is low cost, but the disadvantage is that it cannot accurately detect, and there are easy misdetections, missed detections, etc.; another method is automated measurement. The actuator is installed in an automated measurement device to measure its output torque and angle parameters. This method has high cost, complex implementation, and low detection efficiency.

[0005] Therefore, in combination with the above existing technical problems, it is necessary to provide a new technical solution. Summary of the Utility Model

[0014] As a preferred scheme of the off-line detection device for automotive actuators of the present utility model, it further includes a base. The test support and the slide rail are both fixedly installed on the base.

[0015] As a preferred scheme of the off-line detection device for automotive actuators of the present utility model, it further includes a slide table. The test piece mounting seat is fixedly installed on the slide table, and the slide table is slidably installed on the slide rail.

[0016] As a preferred scheme of the off-line detection device for automotive actuators of the present utility model, the test piece mounting seat is detachably installed on the slide table.

[0041] In the example, the output shaft of the test piece 9 accommodated in the receiving groove is coaxially arranged with the quick-connect rotating shaft 3.

[0042] In the example, the test piece mounting seat 5 is used to mount the test piece 9. The test piece 9 is placed in the receiving groove of the test piece mounting seat 5 and is clamped by it. The test piece 9 can only move in the vertical direction to facilitate the placement and removal of the test piece 9.

[0043] In a preferred embodiment, as Figure 1-2 shown, the angle sensor 1 and the test piece mounting seat 5 are respectively located on both sides of the test support 2. A through hole is opened on the test support 2. The rotating shaft of the angle sensor 1 passes through the through hole and extends to the side close to the test piece mounting seat 5.

[0044] Preferably, the quick-connect rotating shaft 3 sleeved on the rotating shaft also passes through the through hole and extends to the side close to the test piece mounting seat 5. In the example, a bearing 22 is further provided in the through hole, and the quick-connect rotating shaft 3 is rotatably installed in the through hole through the bearing 22.

[0045] Preferably, the quick-connect rotating shaft 3 is installed at the axis center of the bearing 22.

Preferably, the slide rail 6 is fixedly installed on the base 7. In the example, the length direction of the slide rail 6 is consistent with the length direction of the quick-connect rotating shaft 3. When the test piece is ready for testing, the test piece mounting seat 5 is pushed along the slide rail towards the quick-connect rotating shaft until the output shaft of the test piece is inserted into the insertion hole or the insertion pin of the quick-connect rotating shaft, and the output shaft is coaxially connected to the quick-connect rotating shaft. Then, a control cable is inserted into the interface of the test piece to enable the test piece to work. The test piece is rotated by a set angle clockwise and counterclockwise along its output shaft respectively, and then the actual rotation angle of the test piece on the angle sensor is observed to detect whether the test piece is working properly. If abnormalities such as the test piece not rotating, skipping teeth, insufficient torque output, or excessive output angle error occur, they can all be directly detected and judged to achieve the purpose of detecting the test piece.

[0049] Preferably, it further includes a slide table 8. The test piece mounting seat 5 is fixedly installed on the slide table 8, and the slide table 8 is slidably installed on the slide rail 6. In the example, the test piece mounting seat 5 is detachably installed on the slide table 8. By detachably installing the test piece mounting seat, when testing different models of test pieces, only the test piece mounting seat, the quick-connect rotating shaft, and the load spring need to be replaced, which is simple, convenient, and low-cost.

[0050] In the example, a slider is installed at the bottom of the sliding table 8, and the slider is slidably installed on the slide rail 6. Preferably, a limiting structure is provided on the slider, and the limiting structure can limit the slider at a specified position on the slide rail. In the example, the limiting structure is a bolt, a threaded hole matching the bolt is formed on the slider, and the bolt is screwed into the threaded hole. When the bolt is rotated outwards so as not to contact the slide rail, the slider can slide freely on the slide rail; when the test piece is connected to the angle sensor, the bolt is rotated inwards until it contacts the slide rail, and the slider is fixed on the slide rail and cannot move, and thus the test piece on the sliding table 8 cannot move either.
