Detailed ways

In order to make the technical means, creative features, goals and effects of the present utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

As shown in Figure 1, a checker for detecting the connecting bracket 1 of an automobile comprises a base 2, an operation table 3 for detecting the connecting bracket 1 is arranged on the base 2, and an arc-shaped notch 4 is arranged on one side of the operating table 3, and the arc The bottom surface of the arc-shaped notch 4 is a horizontal plane, and the side surface of the arc-shaped notch 4 is a vertical surface. This arrangement is to make the bottom surface of the notch 4 and the side of the notch 4 coincide with the outer contour of the connecting bracket 1. The bottom surface and sides of the notch 4 are provided with the detected The detection opening 41 corresponding to the connecting bracket 1 .

The base 2 can be made of metal with a cuboid structure. In order to reduce its weight, a hollow shell structure can also be used. The base 2 is provided with a fixing hole 21 for fixing the position of the inspection tool. When using the inspection tool to detect the connecting bracket 1, First of all, the inspection tool should be fixed to prevent inaccurate detection caused by the movement of the inspection tool during operation. At the same time, in order to facilitate the movement of the inspection tool, handles 22 can be provided at both ends of the base 2 .

The inspection tool of the present utility model further includes a fixed pressure rod 6, which includes a fixed column 61, a pressure rod 62, a detection handle 63 and an operating handle 64. The fixed column 61 is arranged on the base 2, and the entire fixed pressure rod 6 The function of fixing; the pressure rod 62 is movably connected with the fixed column 61 through bolts, and the pressure rod 62 can move up and down around the bolt shaft; the detection handle 63 is arranged at the end of the pressure rod 62, on the one hand, it is fixedly connected to the bracket 1 during detection, and on the other hand On the one hand, the flatness of the parts can be detected; the operating handle 64 is arranged on the pressing rod 62, which is convenient for lifting and lowering the pressing rod 62.

The utility model adopting the above-mentioned structure can accurately detect the automobile connection bracket 1 without the need for multiple positioning reference measurements and coordinate conversions, overcomes the shortcomings of low measurement efficiency and difficulty in meeting production requirements, and improves the efficiency of detection work.

The working process of the vehicle connection bracket 1 inspection tool of the present utility model in detecting workpieces will be described below.

Because the base 2 is the benchmark for the design, installation and debugging of the entire inspection tool, when the operation table 3 is fixedly installed with the base 2, it should first be positioned according to the dimensional tolerance range required by the relevant dimensions to be detected by the same series of connected brackets 1 to be detected, and then in the After the fixed connection and the inspection tool are installed, the workpiece connection bracket 1 can be inspected.

First put the connecting bracket 1 to be detected into the notch 4 of the console 3, so that the outer contour of the connecting bracket 1 matches the bottom surface and the side of the notch 4, and then the connecting bracket 1 can be pressed by the fixed pressure rod 6 to make it Can no longer move. After making the above preparations, observe whether the outer contour of the detected connecting bracket 1 matches the bottom surface of the notch 4 of the operating table 3 and the side of the notch 4. If it does not match, the connecting bracket 1 is unqualified. If it matches, the next step of testing can be carried out. In order to improve the accuracy of the inspection tool for detecting the connection bracket 1 as much as possible, the inspection tool also includes a detection cover (not shown in the figure), the outer contour of the detection cover matches the outer contour of the connection bracket 1, and the connection bracket 1 is placed in the gap of the console 3 After step 4, the detection cover can be fastened on the surface of the connecting bracket 1 to further detect the matching degree of the outer contour of the connecting bracket 1 .

Take out the detection rod 5 corresponding to it according to the detection hole as required, insert the detection rod 5 in the hole to be detected, and insert it into the detection opening on the bottom surface of the notch 4 corresponding to it through the hole on the connected bracket 1 to be detected, If it is inserted all the way to the bottom, it means that the hole distance of this hole is correct. If the hole at this time can be coupled with the detection rod, it means that the hole diameter of this hole is qualified, thus indicating that this hole is qualified; If they are all unqualified, then this hole is unqualified, that is, this connecting bracket 1 is unqualified. After one hole is detected, another detection rod 5 of another caliber is inserted into another hole to be detected, and the same detection method as above is adopted until all the holes to be detected are detected.

After the detection is complete, pull out all the detection rods 5 and put them back to their original positions, which can prevent the loss of the detection rods 5, thereby making it easy to unload the connection bracket 1 and then install the next connection bracket 1 that needs to be detected. All the connection brackets 1 are detected sequentially, so that the detection can be completed quickly.

In this way, the automobile connecting bracket 1 can be detected quickly and accurately, which solves the problem that the automobile connecting bracket 1 is difficult to detect. It can be detected whether the relevant dimensional accuracy of the part is within the required dimensional tolerance range through one positioning reference, and it is not necessary. Multiple positioning reference measurements and coordinate conversions are required, which overcomes the shortcomings of low measurement efficiency and difficulty in meeting production requirements, and improves the efficiency of inspection work.
