Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts detection, in particular to a quality detection device for automobile parts. Background Art

[0002] Automotive parts are the fundamental components of a car, including the engine, transmission, suspension, brakes, electrical system, body, and chassis. These components work together to ensure the car's performance, safety, and comfort. Each component plays a vital role in the overall operation of the car and is a key element in its design and manufacturing. The quality of a car is directly related to the quality of its components. Therefore, before using auto parts, they must be inspected for quality. One of the inspections is to check for cracks on the surface of the components.

[0003] The patent document with publication number CN213658645U in the prior art provides a surface quality inspection device for automobile parts. The device can first use an ultrasonic flaw detector to make a preliminary judgment on the automobile parts, and then use the image collected by the macro camera for verification. The detection efficiency is high and the accuracy is high. Although the device has many beneficial effects, the following problems still exist: when using a clamp to clamp and rotate the automobile parts, the clamp simply clamps the parts through two plate-like structures. The parts are easily deflected due to the centrifugal force during rotation, especially special-shaped parts are more likely to deflect during rotation, which makes it easy for the parts to be fixed and unstable, and thus easily affects the acquisition and recognition of the image of the parts. For this reason, we propose a quality inspection device for automobile parts. Utility Model Content

[0004] The purpose of the utility model is to provide a quality inspection device for automobile parts, so as to solve the problem that parts are prone to deflection when rotating, as mentioned in the above background technology.

[0011] Preferably, a vertical hole matching the support arm is opened on the side wall of the outer sleeve, and the outer sleeve is a cylindrical structure.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model clamps the parts to the meshing turntable by cooperating with the clamping plate, and then rotates the rotating screw to make the sliding block move downward inside the outer sleeve. At this time, the support arm cooperates with the sliding block to move downward so that the pressure plate is pressed on the top of the automobile part. Then the servo motor runs through the gear to drive the meshing turntable to rotate to realize the rotation of the part. At this time, the pressure plate cooperates with the bearing outside the lower pressure rod to follow the rotation of the part and press the part, thereby cooperating with the pressure plate of the lower pressure cylinder of the support arm to press the automobile part, which can avoid the problem of deflection of the automobile part when the meshing turntable rotates after clamping, which is beneficial to improving the clamping stability of the automobile part when it rotates, and can also improve the accuracy of image acquisition, which is further beneficial to improving the accuracy of quality inspection.

[0014] 2. When the meshing turntable drives the automobile parts to rotate, the joint of the utility model is connected to an external air pump, which uses the external air pump to provide high-pressure gas to the rotating tube. At this time, the air flow is ejected from the nozzle of the rotating tube to the clamped parts, so that the air flow can be used to remove dust and clean the outer wall of the rotating parts, reducing the influence of dust attached to the surface of the automobile parts on the quality inspection and identification judgment of the automobile parts after photography, which is conducive to improving the cleanliness of the surface of the automobile parts and the accuracy of inspection and identification.
