Description

Technical Field

[0001] This utility model relates to the field of inspection tool technology, specifically to an inspection tool for grille trim strips. Background Technology

[0002] In the automotive manufacturing industry, grille trim, as an important decorative component of a vehicle's exterior, directly impacts the overall quality and aesthetics of the vehicle through its assembly quality and appearance. However, current trim inspection processes typically rely on simple manual measuring tools such as calipers and rulers to measure the trim's dimensions. This method is not only inefficient but also fails to accurately measure the fit gap between the trim and its mounting position, and cannot fully simulate the actual stress state of the trim during vehicle assembly. Therefore, it often cannot accurately identify problems such as deformation, misalignment, or dimensional deviations in the trim, leading to quality issues like loosening or warping during actual installation, severely affecting product consistency and assembly reliability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This embodiment provides the following technical solution:

[0022] A gauge for grille trim includes a base 1, a pad 2 with an arc-shaped top at the upper end of the base 1, a contour block 3 on the upper surface of the pad 2, the contour block 3 matching the groove structure of the trim body 9, and a clamping component above the contour block 3 for detecting the fitting gap between the trim body 9 and the contour block 3.

[0023] Specifically, the upper surface of the pad 2 is provided with a contour block 3 that matches the groove structure of the trim body 9. The contour block 3 is precisely made according to the actual shape of the trim body 9 and can perfectly fit the groove part of the trim body 9. A pressing component is provided above the contour block 3 to simulate the pressure environment under actual installation conditions, pressing the trim body 9 tightly against the contour block 3. In this way, the fitting gap between the trim body 9 and the contour block 3 can be effectively checked, thereby determining whether the trim meets the standard.

[0024] By applying a certain pressure to the trim body 9 and observing its fit with the contour block 3, the dimensional accuracy and error of the trim body 9 can be accurately detected. The tight fit between the contour block 3 and the trim body 9 can be used to check whether the shape of the trim body 9 is accurate and whether there are any deformations or manufacturing defects. The clamping component simulates the pressure conditions of the trim body 9 in actual use, which helps to evaluate the assembly quality of the trim body 9 on the vehicle and ensure that it will not loosen or fall off in actual use. Through this specially designed inspection tool, rapid and accurate inspection can be carried out, and quality control steps can be completed efficiently on the production line to identify and solve potential problems in a timely manner, thereby improving overall production efficiency and product quality.

[0025] The rear end of the pad 2 is provided with a horizontal plate 12, and the horizontal plate 12 is fixedly connected to the base 1. The clamping assembly includes a clamping seat 11, which is connected to the horizontal plate 12 through a hydraulic cylinder 13. Multiple cylinders 15 are installed inside the clamping seat 11, and the telescopic end of the cylinder 15 extends to the outside of the clamping seat 11 and is connected to a clamping block 14.

[0026] Specifically, the hydraulic cylinder 13 is connected to the horizontal plate 12 to realize vertical lifting and lowering movement. Multiple cylinders 15 are installed inside the pressing seat 11. Their telescopic ends drive the pressing block 14 to apply pressure to the trim strip. The hydraulic cylinder 13 pushes the pressing seat 11 to move downward, so that the pressing component is close to the surface of the trim strip. Multiple cylinders 15 in the pressing seat 11 extend synchronously, driving the pressing block 14 to contact the trim strip body 9 and apply uniform pressure. By combining multiple cylinders 15 and pressing block 14, it can adapt to the curvature changes of different parts of the trim strip and ensure full fit test.

[0027] Hydraulic cylinder 13 controls the overall downward pressing of clamping seat 11, and pneumatic cylinder 15 controls the movement of clamping block 14, which can simulate the stress state in the actual assembly process. Multiple clamping blocks 14 apply pressure at the same time, which can effectively detect whether each part of the trim strip is completely in contact with the contour block 3, and whether there are gaps or deformations.

[0028] The pad 2 has stops 4 on both sides. The base 1 has a moving groove 6 inside, and a double-acting screw 10 is installed inside the moving groove 6. The stops 4 are connected to the double-acting screw 10 through the moving blocks. One end of the double-acting screw 10 extends to the outside of the base 1 and is connected to an adjusting handle 5. The upper surface of the base 1 is provided with a scale 8, and the scale 8 is located at the front end of the pad 2. A rod 7 is fixedly installed at the front end of the stops 4.

[0029] Specifically, the trim strip body 9 is placed on the contour block 3. Rotating the adjusting handle 5 causes the bidirectional lead screw 10 to rotate, thereby driving the stop block 4 to move left and right along the moving groove 6. The change in distance between the stop blocks 4 can be read by the position of the scale rod 7 on the ruler 8, thus obtaining the actual length of the trim strip body 9. If the trim strip cannot completely fit the stop block 4 or the gap is too large, it indicates a deviation in its length or shape, requiring rework or adjustment. By adjusting the position of the stop block 4 and using the ruler 8 and scale rod 7, the actual length of the trim strip can be quickly and accurately measured to determine whether it meets the design tolerance requirements.

[0030] Working principle: During testing, after the trim strip body 9 is placed on the upper surface of the contour block 3, the hydraulic cylinder 13 drives the pressing seat 11 to press down to an appropriate height. Then, the cylinder 15 moves synchronously, pushing the pressing block 14 to apply uniform pressure to the trim strip. By pressing the trim strip at multiple points with the pressing block 14, the pressure environment of the trim strip during actual assembly is simulated, thereby checking the fitting gap between the trim strip and the contour block 3 and judging whether there are problems such as deformation, misalignment, or dimensional deviation. Movable stops 4 are provided on both sides of the pad 2. The two ends of the trim strip should be tightly attached to the stops 4 to achieve precise positioning. The stops 4 are connected to the bidirectional lead screw 10 installed in the moving groove 6 inside the base 1 through the moving block. Rotating the adjusting handle 5 located outside the base 1 can drive the bidirectional lead screw 10 to rotate, so that the two stops 4 on both sides move inward or outward synchronously to accommodate trim strips of different specifications. A scale 8 is provided at the front end of the base 1, and a scale rod 7 is fixed at the front end of the stops 4. The distance between the stops 4 can be read by the position of the scale rod 7 on the scale 8, which is the actual length of the trim strip body 9. If the trim strip cannot fit completely against the two blocks 4, or if there is a noticeable gap between it and the contour block 3, it indicates that there is a deviation in its length or shape, and it needs to be reworked.
