At the same time, the present invention also adopts a new detection method:

There are three states of the threshold assembly, and the product size of each assembly is relatively long. If the inspection tool is developed and invested in each assembly, three sets of threshold assembly inspection tools are required. The development cost is high, the floor space is large, and the practicability is poor. Inconvenience and many other reasons, in order to solve the previous problems, consider that a set of left and right door sill assemblies are arranged on the left and right of the inspection board. It is fixed on the base plate of the inspection tool, but the detection of threshold assemblies in different states is the most prominent problem that needs to be solved. The shape of the door sill assembly is different, and the boundary between the periphery and the body is also different, and the matching relationship between each set of door sill assembly and the body includes the left, right and upper areas. The shapes of the left and right sides are completely different. It is necessary to design a detection mechanism that slides up and down. The sliding fixed positions are divided into three positions: upper, middle and lower. Each position corresponds to a detection block in one state, and the three detection blocks are arranged and fixed in the same On the large slidable slider, three different profiles can be detected. For the other side, when sliding up and down, it will interfere with the movement of the product. It is also necessary to design corresponding lateral sliding at different positions of the upper, middle and lower positions. Sliding up and down avoids interference with the product, and sliding left and right ensures that the detection block is installed in the theoretical detection. At the same time, the upper part of the three products has the same shape, and a unified detection block can be designed to realize the function of profile detection in the same area of the three shapes.

1. The inspection tool base plate is placed vertically. The inspection tool base plate is equivalent to the car body. The product is assembled from the side and front in the simulated loading direction. The left and right products are assembled on the left and right sides of the vertically placed inspection tool base plate, which completely simulates loading left and right. It is easy to assemble and can be placed vertically to save space.

2. On the large base plate of the inspection tool, the door sill assemblies in the three states are correspondingly designed to correspond to all the positioning and fixed connection points that are fixedly connected to the body to ensure that the door sill assemblies in the three states can be universally inspected for the same base plate (involving different products, But with the same fixed position, the same fixed point can be designed on the inspection tool for fixing.

3. Three-state threshold assembly, at the position of the same profile on the upper part, the inspection tool corresponding to the same profile detection block is designed to realize the detection of three states. Similarly, the inspection block of the inspection tool and the inspected product are offset by a certain distance (3mm) to detect the product gap profile or flush (0mm) profile.

4. The three-state threshold assembly has different shapes in the left area. The inspection tool is designed with a fixed support panel, and a slide rail with a certain movement direction is designed on the panel. The different shapes of the product in this area correspond to three different detection blocks. (Detection blocks 1, 2, 3) are designed to be installed on another panel, and this panel is designed on the above-mentioned slide rail. When detecting different products, the panel is deduced along the movement direction of the slide rail. Inspection of state product profile. Similarly, the inspection block of the inspection tool and the inspected product are offset by a certain distance (3mm) to detect the product gap profile or flush (0mm) profile.

5. The three-state threshold assembly has different shapes in the right area, and the products are quite different. Simply design a slide rail in the upper and lower directions. When the detection blocks of the three states are arranged, there is a non-corresponding detection block and the detection product is transported to interfere. Therefore, it is necessary to add a laterally moving slide rail to avoid interference, that is, when sliding up and down to the corresponding detection area, the lateral return of the detection block is performed. The inspection tool is designed with a large fixed support plate, and two slide rails that move up and down are designed on the panel, and the upper and lower rails are designed with holes and pins at three heights, and the theoretical height is fixed by the pins. A small support plate is designed on the large support plate, and two laterally moving slide rails are designed on the small support plate to ensure a certain distance of lateral sliding to avoid interference, and fixed holes and latches are designed at the corresponding positions on the small support plate to ensure the lateral position. After being in place, the three-state detection blocks (detection blocks 1, 2, and 3) are fixed. Similarly, the inspection block of the inspection tool and the inspected product are offset by a certain distance (3mm) to detect the product gap profile or flush (0mm) profile.

Compared with the related art, the inspection tool for realizing the three-state threshold assembly provided by the present invention has the following beneficial effects:

1. The inspection tool provided by the present invention can complete the profile inspection of three different thresholds of Great Wall P05 automobiles, so that enterprises no longer need to use three different inspection tools to complete the inspection of three different thresholds, which greatly saves It reduces the development cost of the inspection tool of the enterprise, and can reduce the floor space of the inspection tool, which is convenient for the enterprise to use. In the actual use process, the set threshold installation mechanism can match the plastic buckle position and the position of the hinge structure hole on the three different thresholds. , during installation, the plastic clip can be clamped by the first pneumatic clamp or the second pneumatic clamp, and the set hinge structure hole pin is inserted into the hinge structure control on the threshold, or the threshold is clamped into the inner side of the positioning block, thereby It can realize the fixing work of the door sill, simulate the state of the door sill being loaded into the vehicle, and then the profile detection and detection of the two ends of the door sill can be performed by the left profile detection mechanism and the right profile detection mechanism;

The embodiment of the present invention utilizes the following detection methods for detection: as shown in Figure 10 to Figure 13:

There are three states of the threshold assembly, and the product size of each assembly is relatively long. If the inspection tool is developed and invested in each assembly, three sets of threshold assembly inspection tools are required. The development cost is high, the floor space is large, and the practicability is poor. Inconvenience and many other reasons, in order to solve the previous problems, consider that a set of left and right door sill assemblies are arranged on the left and right of the inspection board. It is fixed on the base plate of the inspection tool, but the detection of threshold assemblies in different states is the most prominent problem that needs to be solved. The shape of the door sill assembly is different, and the boundary between the periphery and the body is also different, and the matching relationship between each set of door sill assembly and the body includes the left, right and upper areas. The shapes of the left and right sides are completely different. It is necessary to design a detection mechanism that slides up and down. The sliding fixed positions are divided into three positions: upper, middle and lower. Each position corresponds to a detection block in one state, and the three detection blocks are arranged and fixed in the same On the large slidable slider, three different profiles can be detected. For the other side, when sliding up and down, it will interfere with the movement of the product. It is also necessary to design corresponding lateral sliding at different positions of the upper, middle and lower positions. Sliding up and down avoids interference with the product, and sliding left and right ensures that the detection block is installed in the theoretical detection. At the same time, the upper part of the three products has the same shape, and a unified detection block can be designed to realize the function of profile detection in the same area of the three shapes.

The inspection tool base plate is placed vertically. The inspection tool base plate is equivalent to the body. The product is assembled from the side and front in the simulated loading direction. The left and right products are assembled on the left and right sides of the vertically placed inspection tool base plate, which completely simulates the loading method of left and right parts. , easy to assemble and vertical placement greatly saves space.

On the large base plate of the inspection tool, the three states of the door sill assembly are correspondingly designed to correspond to all the positioning and fixed connection points that are fixedly connected to the body, so as to ensure that the three states of the door sill assembly can be universally inspected for the same base plate (involving different products, but with For the same fixed position, the same fixed point can be designed on the inspection tool for fixing.

For the three-state threshold assembly, at the upper position of the same profile, the inspection tool correspondingly designed the same profile detection block to realize the detection of three states. Similarly, the inspection block of the inspection tool and the inspected product are offset by a certain distance (3mm) to detect the product gap profile or flush (0mm) profile.

The three-state threshold assembly has different shapes in the left area. The inspection tool is designed with a fixed support panel, and a slide rail with a certain movement direction is designed on the panel. The different shapes of the product in this area correspond to three different detection blocks (detection Blocks 1, 2, 3) are designed to be installed on another panel, and this panel is designed on the above-mentioned slide rail. When detecting different products, the panel is deduced along the movement direction of the slide rail. Type inspection. Similarly, the inspection block of the inspection tool and the inspected product are offset by a certain distance (3mm) to detect the product gap profile or flush (0mm) profile.

The three-state threshold assembly has different shapes in the right area, and the products are quite different. Simply design a slide rail in the up and down direction. When arranging the three-state detection blocks, there is interference between the non-corresponding detection blocks and the detection products. Therefore, It is necessary to add a sliding rail that moves laterally to avoid interference, that is, when sliding up and down to the corresponding detection area, then perform the lateral return of the detection block. The inspection tool is designed with a large fixed support plate, and two slide rails that move up and down are designed on the panel, and the upper and lower rails are designed with holes and pins at three heights, and the theoretical height is fixed by the pins. A small support plate is designed on the large support plate, and two laterally moving slide rails are designed on the small support plate to ensure a certain distance of lateral sliding to avoid interference, and fixed holes and latches are designed at the corresponding positions on the small support plate to ensure the lateral position. After being in place, the three-state detection blocks (detection blocks 1, 2, and 3) are fixed. Similarly, the inspection block of the inspection tool and the inspected product are offset by a certain distance (3mm) to detect the product gap profile or flush (0mm) profile.
