Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts testing, in particular to an actuator support testing mechanism. Background Art

[0002] Actuators are mainly used to open and close the grille of a car and control other parts. Before installation, it is necessary to ensure that the actuator opens and closes the corresponding parts 100%. Therefore, the actuator needs to be tested during its manufacturing process. The traditional testing method is generally to clamp the actuator on a fixed test mechanism, and then manually adjust the fixture to achieve static and dynamic testing of the actuator.

[0003] However, we found in actual use that the traditional testing method requires repeated confirmation and adjustment of the position to ensure the accuracy and reliability of the test. This operation method is not only time-consuming and labor-intensive, but also easily introduces human errors, greatly reducing the test efficiency. For this reason, we proposed an actuator support test mechanism. Utility Model Content

[0035] The switching assembly 7 includes a rotating shaft 1 71 and a rotating shaft 2 72 rotatably arranged on the shift slide 51, the rotating shaft 1 71 is connected to the output end of the test motor 52 through a coupling, the rotating shaft 2 72 is connected to the torque sensor 53 through a coupling, a shift plate 73 is arranged on the shift slide 51, an axial adjustment member 8 for driving the shift plate 73 to move and adjust is arranged on the shift slide 51, and a transmission member 9 for controlling the connection relationship between the rotating shaft 1 71 and the rotating shaft 2 72 is arranged on the shift plate 73;

[0036] The axial adjustment member 8 includes a second shift cylinder 81 disposed on the shift slide 51, the end of the second shift cylinder 81 is connected to the shift plate 73, two linear guide rails 82 are disposed on both sides of the shift slide 51, and a second sliding block 83 used in conjunction with the second linear guide rail 82 is disposed at the bottom of the shift plate 73;

[0038] When in use, the staff installs the actuator body 2 on the fixed seat 3, and the shift cylinder 1 61 is used as the shift member 6, which drives the shift block 62 through its telescopic movement, and then pushes the shift slide 51 to slide on the linear guide rail 1 63 on the mechanism body 1.
