Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile component inspection tools, and more specifically, to an automobile component inspection tool. Background Art
[0002] In the prior art, there are some significant limitations in the use of automotive parts inspection fixtures, especially in the fixing and testing of parts. Usually these inspection fixtures are designed to be fixed by a single point, which may be sufficient when dealing with straight or flat parts, but when it comes to complex curved or special-shaped parts, the single-point fixing method is inadequate. Due to the variable shapes of curved parts, it is difficult for single-point fixing to provide sufficient stability and uniform pressure distribution, which leads to unreliable fixation and increases the risk of movement or slippage of parts during testing. In addition, existing single-point fixing fixtures usually do not allow the fixing force to be adjusted, which means that the staff cannot adjust the fixing pressure according to the material or design requirements of the parts. Too large or too small a fixing force may cause damage to the parts or fail to effectively maintain their position, thereby affecting the detection accuracy and safety of operation.
[0003] The limitations of this fixing method not only reduce the reliability and efficiency of the inspection, but may also cause damage to parts during the inspection process, especially those precision parts whose surfaces are easily scratched or indented. In high-speed or high-pressure environments, unstable fixing is more likely to cause accidents, such as parts falling off or tool damage, which in turn brings safety risks and possible economic losses.

[0030] In this embodiment, when fixing, the fixing sleeve 2 is driven downward by the cylinder 15, so that the multiple contact balls 7 are pressed against the automobile parts. Since the automobile parts are arranged as curved surfaces, when the thrust received by each telescopic rod 6 is greater than the friction between the elastic strip 8 and the telescopic rod 6, it will move, so that the multiple contact balls 7 are adapted to the curved surface of the automobile parts, thereby ensuring the fixing process. When the friction of the telescopic rod 6 needs to be adjusted, the push sleeve 10 can be driven to move by the rotation of the threaded sleeve 9, and then the push sleeve 10 is pressed against the telescopic sleeve 5, and the top sleeve 3 is in a fixed state. Therefore, the multiple elastic strips 8 are pushed and then pressed against the telescopic rod 6, thereby increasing the friction, thereby changing the fixing strength of the telescopic rod 6, so the corresponding contact strength can be changed according to the corresponding situation.
[0031] See also Figure 1As an implementation of the moving mechanism: the moving mechanism includes a vertical block 14 and a cylinder 15, the vertical block 14 is installed on the base plate 1, the cylinder 15 is installed on the vertical block 14, a follower sleeve 16 is provided on the protruding end of the cylinder 15, a protruding block 17 is provided on the vertical block 14, the follower sleeve 16 is slidably connected to the protruding block 17, the fixed sleeve 2 is threadedly connected to the follower sleeve 16, and the hexagonal section 4 is attached to the follower sleeve 16, a slide rail 18 is provided on the base plate 1, a slider 19 is slidably provided on the slide rail 18, a moving plate 20 is provided on the slider 19, automobile parts are placed on the moving plate 20, and handles 21 are respectively provided on the moving plate 20 and the base plate 1.
[0032] More specifically, when inspection is required, the automobile parts are first placed on the movable plate 20, and then the movable plate 20 is moved by the sliding of the slide rail 18 and the slider 19, and then the automobile parts are moved to the corresponding position, and then the fixing process is completed under the action of the cylinder 15, and then the inspection process is carried out.
[0033] In summary, when the overall equipment is in use or running: when fixing, the cylinder 15 drives the fixing sleeve 2 to move downward, so that the multiple contact balls 7 are pressed against the automobile parts. Since the automobile parts are arranged with curved surfaces, when the thrust received by each telescopic rod 6 is greater than the friction between the elastic strip 8 and the telescopic rod 6, it will move, so that the multiple contact balls 7 are adapted to the curved surface of the automobile parts, thereby ensuring the fixing process. When the friction of the telescopic rod 6 needs to be adjusted, the rotation of the threaded sleeve 9 can drive the movement of the push sleeve 10, and then the push sleeve 10 is pressed against the telescopic sleeve 5, and the top sleeve 3 is in a fixed state. Therefore, the multiple elastic strips 8 are pushed and then pressed against the telescopic rod 6, thereby increasing the friction, thereby changing the fixing force of the telescopic rod 6, so the corresponding contact force can be changed according to the corresponding situation.
[0034] When inspection is required, the automobile parts are first placed on the movable plate 20, and then the movable plate 20 is moved by the sliding of the slide rail 18 and the slider 19, and then the automobile parts are moved to the corresponding position, and then the fixing process is completed under the action of the cylinder 15, and then the inspection process is carried out.
