[0002] During the production process of automobile parts, due to the influence of human factors, equipment factors, etc., the through holes of automobile parts may be missed, the position may deviate, or the through hole diameter may deviate, which will affect the subsequent assembly of automobile parts. Therefore, it is necessary to detect the leak holes of automobile parts. When an automatic detection machine performs leak hole detection on automobile parts, it is often necessary to use a device to position the automobile parts to prevent the automobile parts from moving during detection or when conveying the automobile parts into the automatic detection machine, resulting in inaccurate detection results.

However, the existing auto parts leak detection and positioning clamping device only clamps the auto parts through a shape-fixed clamping plate. The clamping plate cannot adapt to the external shape of the auto parts, making the clamping of the auto parts unstable and the auto parts prone to displacement. Utility Model Content

[0019] The present utility model is implemented as follows Figures 1 to 3 As shown in, a leak detection, positioning and clamping device for automobile parts comprises a base 1, and sliders 2 for limiting sliding in the front and rear directions are provided on the left and right sides of the top surface of the base 1, and a mounting plate 20 is provided on the top surface of each slider 2, and a cylinder 21 with an output end facing the center of the base 1 is provided on the mounting plate 10, and a connecting block 22 is provided on the output end of the cylinder 21. The connecting block 22 is a cylindrical structure, and a clamping pad 3 is provided on the surface of the connecting block 22 away from the cylinder 21. The clamping pad 3 is a rubber pad. The rubber pad can not only elastically deform to wrap the outside of the automobile part, but also protect the automobile part when clamping the automobile part without scratching the automobile part. Preferably, the end surface of the clamping pad 3 close to the center of the base 1 is provided with anti-slip stripes, so that the clamping is more stable, that is, the right side surface of the clamping pad 3 on the left is provided with anti-slip stripes, and the left side surface of the clamping pad 3 on the right is provided with anti-slip stripes. Anti-slip stripes are provided, and connecting rods 23 are provided on the front and rear sides of the connecting block 22. A sleeve 4 perpendicular to the clamping pad 3 is provided at the end of the connecting rod 23 away from the connecting block 22, and a telescopic rod 40 connected to the clamping pad 3 is slidably provided in the sleeve 4. The telescopic rod 40 is a rectangular structure, and the interior of the sleeve 4 is a rectangular hollow structure. The telescopic rod 40 is matched and slidably provided in the sleeve 4. The end of the telescopic rod 40 away from the clamping pad 3 is threadedly connected with an adjusting screw 41, and the end of the adjusting screw 41 away from the telescopic rod 40 passes through the sleeve 4. A base through hole located between the two sliders 2 is provided on the top surface of the base 1, and a light-transmitting plate 5 is provided in the base through hole. The light-transmitting plate 5 is a transparent and colorless tempered glass or a transparent and colorless acrylic plate. When the light-transmitting plate 5 is tempered glass, a transparent protective film is provided on the light-transmitting plate 5 to prevent scratches on the glass.
[0020] The sliding slider 2 is limited according to the size and external shape of the automobile part, so as to adjust the clamping position, and then the cylinder 21 drives the clamping pad 3 to clamp the automobile part, and then the adjusting screw 41 is rotated to drive the telescopic rod 40 to extend and retract, so that the two sides of the clamping pad 3 move, so that the clamping pad 3 can wrap and clamp the outside of the automobile part. That is, this positioning and clamping device can adapt to automobile parts of different sizes and external shapes, and clamp the automobile parts more stably. The light source of the detection machine is irradiated on the automobile part from below through the light-transmitting plate 5, so that the position with the through hole on the automobile part is in a light-transmitting state, which makes it easier to detect whether there is a leak.
[0021] Further improvements, such as Figure 1 and Figure 2 As shown in the figure, a bearing 6 is provided between the adjusting screw 41 and the sleeve 4. The bearing 6 is located on the side of the sleeve 4 away from the clamping pad 3, that is, the left bearing 6 is located on the left side of the sleeve 4, and the right bearing 6 is located on the right side of the sleeve 4. The adjusting screw 41 is rotatably connected to the sleeve 4 through the bearing 6, which makes the rotation of the adjusting screw 41 smoother.
[0022] Further improvements, such as Figure 1 and Figure 3 As shown in the figure, both left and right sides of the top surface of the base are provided with slide grooves 10 extending forward and backward. The slide groove 10 is an inverted T-shaped slide groove 10, and the slider 2 is an inverted T-shaped structure matching the slide groove 10, thereby limiting the upward movement of the slider 2 and preventing the slider 2 from falling out of the slide groove 10 and affecting the clamping of automobile parts.
[0023] Further improvements, such as Figure 1 As shown in the figure, each of the slide grooves 10 is provided with a plurality of sliders 2. Preferably, each of the slide grooves 10 is provided with two sliders 2. Each slider 2 is provided with a cylinder 21 for clamping automobile parts, a clamping pad 3, a sleeve 4, a telescopic rod 40 and an adjusting screw 41, so that the positioning and clamping device can clamp four parts of the automobile parts, making the clamping more stable.
[0024] Further improvements, such as Figure 1 and Figure 3 As shown in the figure, the mounting plate 20 is arranged on the side of the top surface of the slider 2 close to the center of the base 1, and a threaded through hole is provided on the side of the top surface of the slider 2 away from the center of the base 1. The slider 2 is provided with a limit screw 7 threadedly connected to the threaded through hole, and each slider 2 is provided with two limit screws 7. The two limit screws 7 are arranged at intervals in the front and rear directions on the top surface of the slider 2. After adjusting the front and rear positions of the slider 2, the limit screws 7 are locked to limit the position to prevent the slider 2 from sliding back and forth.
[0025] Further improvements, such as Figure 1As shown in the figure, limit seats 8 are provided on both the front and rear sides of the top surface of the base 1. The limit seats 8 are rectangular structures extending in the left and right directions. The height of the top surface of the limit seats 8 is not lower than the height of the top surface of the clamping pad 2. The limit seats 8 assist in positioning the automobile parts and facilitate clamping of the automobile parts.
