DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 - 4 as shown, the present utility model provides the following technical solutions:

[0020] An automotive clock spring rotation test structure includes a support member. Along one side of the support member in its own length direction, a linear guide rail 3 is installed. A moving frame 4 is slidably connected to the linear guide rail 3. On the side of the moving frame 4 away from the linear guide rail 3, a driving member is installed. At the bottom of the driving member, a plug-in module 9 is rotatably connected. A protrusion that inserts into the axis of the automotive clock spring protrudes from the bottom of the plug-in module 9.

[0021] Through the above technical solution, when a fixture (not shown in the figure) drives the automotive clock spring to be tested to rotate under the plug-in module 9, by the operation of the linear guide rail 3, the moving frame 4 moves along the linear guide rail 3. And when the moving frame 4 moves, it will drive the driving member to move together. The movement of the driving member will drive the plug-in module 9 to move, so that the protrusion at the bottom of the plug-in module 9 inserts into the automotive clock spring. After the plug-in module 9 is connected, in the channel of the plug-in module 9, a two-dimensional voltage test is carried out on the automotive clock spring. After the two-dimensional voltage test, a release and clamping step is performed, and by the operation of the driving member, the plug-in module 9 is driven to rotate, and then the plug-in module 9 drives the automotive clock spring to rotate, so as to perform a rotation test step.

[0022] In addition, in the present utility model, regarding the above plug-in module 9:

[0023] As Figures 1 - 4 shown, the plug-in module 9 includes a movable seat 92. At the bottom of the movable seat 92, two pin positioning blocks 94 are symmetrically and fixedly connected, and a guide shaft 93 is also fixedly connected to the bottom of the movable seat 92. The guide shaft 93 is located between the two pin positioning blocks 94.

[0024] In this embodiment, when the plug-in module 9 moves, the movable seat 92 moves, thereby driving the pin positioning blocks 94 to move, making it more accurate when the guide shaft 93 inserts into the automotive clock spring.

[0025] In order to make the device more stable when testing the automotive clock spring, as Figure 4 shown, a guide rod 97 is fixedly connected to the top of the movable seat 92. A movable connecting seat 91 is sleeved on the guide rod 97, and a spring 96 is also sleeved on the guide rod 97. The spring 96 is located between the movable seat 92 and the connecting seat 91.

[0026] In this embodiment, when the movable seat 92 moves, through the cooperation of the guide shaft 93, the connecting seat 91 and the spring 96, the guide shaft 93 is facilitated for release and clamping operations.

[0027] In order to make it easier for the device to align with the automotive clock spring during detection and improve the plugging and unplugging efficiency, as Figure 4As shown, two connector brackets 95 are symmetrically and fixedly connected to the bottom of the movable seat 92. The guide shaft 93 is located between the two connector brackets 95, and the pin positioning block 94 is located below the connector brackets 95.

[0028] In this embodiment, the connector brackets 95 are supported by the movable seat 92, and the pin positioning block 94 is supported by the connector brackets 95, so that the guide shaft 93 can be easily aligned and inserted into the automotive clock spring.

[0029] Specifically, in one embodiment, regarding the above-mentioned driving member, as Figures 1 - 3 shown, the driving member includes a servo motor 6. The output end of the servo motor 6 is connected to a speed reducer 7. And a side plate 5 is fixedly connected to one side of the servo motor 6 close to the linear guide 3. The side plate 5 away from the servo motor 6 is fixedly connected to the moving frame 4. The output end of the speed reducer 7 is connected to an encoder 8, and the output end of the encoder 8 is connected to the top of the connecting seat 91.

[0030] In this embodiment, when it is necessary to drive the guide shaft 93 to rotate, the servo motor 6 works, thereby driving the speed reducer 7 to work. Through the cooperation of the speed reducer 7 and the encoder 8, the connecting seat 91 is driven to rotate, and then the guide shaft 93 is driven to rotate.

[0031] Specifically, in one embodiment, regarding the above-mentioned supporting member:

[0032] As Figures 1 - 3 shown, the supporting member includes a bottom frame 1. The top of the bottom frame 1 is fixedly connected to a top frame 2. The linear guide 3 is installed on one side of the top frame 2.

[0033] In this embodiment, the top frame 2 is supported by the bottom frame 1, and the linear guide 3 is supported by the top frame 2.
