As shown in Fig. 1 and Fig. 2 , a test tool for the middle horizontal bracket of the front end frame of an automobile includes a base 1, an operating table 2, a positioning reference frame 7 and a support 3. The base plate 6 under the support 3 and the positioning reference frame 7 are fixedly installed on the base 1 respectively, and the base plate 6 is fixedly connected with four operating platforms 2 supported by the supports 3, so that the entire operating platform 2 is more stable. The table is a step-like slope surface, on which a model 8 matching the overall outline of the test part is chiseled, and the bottom surface and the side of the model 8 are provided with detection openings 9 corresponding to the parts to be tested, for example There are two installation holes on both sides of the middle beam of most automobile engines. At this time, the detection opening 9 on the console corresponds to it. The side of the model 8 is provided with a detection groove 10 for detecting the contour of the part. , the positioning reference frame 7 fixedly connected to the base 1 is equipped with 2 frames, the positioning reference frame 7 is provided with an inclined protruding sliding shaft 71, and a slidable triangular baffle 72 is stuck on it, and on the triangular baffle 72 A detection plate 11 with an arc-shaped slot is fixedly connected, and the detection plate 11 and the detection groove 10 can be adapted to each other and can just match each other, and can slide with the triangular baffle 72, and the detection plate 11 can be moved to make the detection groove 10 Match each other, so as to realize the detection function of the middle beam of the car. In addition, the base is the benchmark for the design, installation and commissioning of the entire inspection tool, and there may be multiple positioning holes 12 and multiple mounting holes 13 on it. The base 1 is manufactured as a rectangular parallelepiped hollow shell, with Four rectangular holes 14 are used to reduce the weight of the whole checking fixture. Wherein, the base 1 is also provided with a mounting hole detection plate 18, and the mounting hole detection plate 18 is provided with a mounting hole 13, which communicates with the base 1, and is used for detecting the mounting hole of the beam. Preferably, the positioning reference frame 7 is provided with a bottom plate 15 and is fixedly connected with the base 1 through the installation hole 13 .

The utility model adopting the above-mentioned structure can accurately detect the middle horizontal support of the front frame of the automobile, 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 automobile engine intermediate beam inspection tool of the present utility model in detecting workpieces will be described below.

Because the base 1 is the benchmark for the design, installation and debugging of the entire inspection tool, when the positioning reference frame 7 and the operation platform 2 are fixed and installed with the base 1, they should first be carried out according to the required dimensional tolerance range of the relevant dimensions of the same series of workpieces to be inspected. Positioning, and then fixing the connection with bolts, and after the inspection tool is installed, the workpiece can be inspected.

First the detection plate 11 is moved out of the detection slot 10, and then the middle cross bracket of the automobile front end frame that needs to be detected is arranged according to the detection opening 9 and the detection slot 10 on the model 8 of the console 2, and the middle cross beam of the automobile engine is arranged so that it is consistent with The model 8 matches, and then the detection plate 11 is moved to the detection groove 10, and the detection plate 11 is tightly clamped on the detection groove 10, so that the detection plate 11 cannot be moved. After making the above preparations, observe whether the profile of the detected beam matches the model 8 on the console 2. If not, the entire beam is unqualified; On the detection groove 10 on the platform 2, if the edge shape of the detection bracket does not match the edge shape of the detection groove 10 or the detection plate 11 cannot match the detection groove 10, the bracket is unqualified, otherwise it is qualified; The stent enters the next step of detection to detect the pore diameter and hole distance of the holes on it. Take out the corresponding detection rod according to the required detection hole, insert the detection rod into the hole to be detected, and insert it into the detection opening 9 on the corresponding model 8 through the hole on the part to be detected. It means that the hole distance of this hole is correct. If the hole can be coupled with the detection rod at this time, it means that the hole diameter of this hole is qualified, thus indicating that this hole is qualified; otherwise, if any item or two items are not qualified, then This hole is unqualified, that is, this beam is unqualified. After detecting a hole, take the installation hole 13 of the installation hole position detection plate 18, and use the same detection method above to detect whether it matches, until all the holes that need to be detected have been detected.

After the test is completed, pull out all the detection rods and put them back to their original positions, which can prevent the loss of the detection rods, so that it is convenient to remove the middle horizontal bracket of the front frame of the car and install the next bracket that needs to be detected. All the middle cross brackets of the front frame of the car are detected in turn, so that the detection can be completed quickly.

This method can quickly and accurately detect the middle cross bracket of the front end frame of the car, which solves the problem of difficult positioning of the middle cross bracket of the front end frame of the car, and can detect whether the relevant dimensional accuracy of the part is within the required dimensional tolerance through one positioning reference Within the range, there is no need for multiple positioning reference measurements and coordinate conversions, which overcomes the shortcomings of low face measurement efficiency and cannot meet production requirements, and improves the efficiency of inspection work.
