Background technique

The intermediate shaft assembly is a part of the automobile drive shaft assembly, including the intermediate shaft, the intermediate shaft support frame and the oil seal bushing. The existing detection technology needs to separately detect the outer circle diameter of the intermediate shaft grinding and the relative position between the oil seal bush and the support frame, which has low efficiency and long detection time. In addition, the existing inspection tool does not take into account that the relative position between the oil seal bush and the support frame will change after press-fitting, and the test result has a large error compared with the actual relative position of the intermediate shaft assembly after press-fitting. Especially in mass production, existing inspection techniques cannot guarantee efficiency and quality levels.

Aiming at the above-mentioned prior art, the technical problem to be solved by this utility model is to provide a comprehensive inspection tool for the intermediate shaft assembly, which can simultaneously detect the relative position between the oil seal bushing and the support frame and the grinding surface of the intermediate shaft. circle diameter, and can reduce errors.

In order to achieve the above object, the technical scheme that the utility model takes is:

The comprehensive inspection tool of the intermediate shaft assembly provided by the utility model includes a base, a measuring head and a measuring scale, and a clamping device matched with the supporting frame of the intermediate shaft is fixed on the base; the measuring scale and the measuring head are fixedly connected together , both are installed on the base through their corresponding guide rails, and can slide together on their respective guide rails, the direction of the guide rails is consistent with the axial direction of the intermediate shaft assembly clamped by the clamping device; the measuring The head is provided with a through hole that matches the end of the intermediate shaft sleeve with the oil seal bush. In the detection state, the through hole is placed on the end of the intermediate shaft sleeve with the oil seal bush and pressed to the oil seal bush; the probe also has an intermediate shaft. Outer diameter detection mechanism.

The comprehensive inspection tool of the intermediate shaft assembly also includes a special zero calibration plate.

The measuring head on the comprehensive inspection tool of the intermediate shaft assembly and the above-mentioned clamping device can be replaced to adapt to intermediate shaft assemblies of different specifications.

The above-mentioned clamping device is positioned on the base of the inspection tool through the positioning pin; the intermediate shaft assembly is positioned on the clamping device through the positioning pin and manually clamped.

The utility model adopts the above-mentioned technical scheme, realizes the function of simultaneously detecting the relative position between the oil seal bushing and the support frame and the outer diameter of the intermediate shaft grinding, and improves the efficiency; and simulates the actual loading state of the intermediate shaft assembly, reducing the measurement error .

Detailed ways

The specific implementation of the present utility model is further described by referring to the accompanying drawings and the specific description of the embodiments, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present utility model.

Referring to the accompanying drawings, the utility model provides a comprehensive inspection tool for intermediate shafts. The inspection tool is mainly composed of a clamping device 1, a measuring head 2, a measuring scale 3, a base 4 and a zero calibration plate. The clamping device 1 is positioned on the base 4 with positioning pins and fastened with bolts, and cooperates with the intermediate shaft support frame. Both the measuring head 2 and the measuring scale 3 are installed on the base through corresponding guide rails. The measuring head and the guide rails are The height can be fine-tuned by bolt fastening. The measuring head 2 and the measuring scale 3 are fixedly connected together, and the direction of the guide rail is consistent with the axial direction of the clamped intermediate shaft assembly 5 in the testing state. The measuring head 2 is provided with a through hole matching with the end of the intermediate shaft sleeve with the oil seal bushing, and an intermediate shaft outer diameter detection mechanism 6, which can detect the outer diameter of the intermediate shaft at the same time. Both the measuring head 2 and the clamping device 1 can be replaced. If there are products of other specifications to be tested, it is only necessary to replace the two with those suitable for the product to be tested.

During detection, the intermediate shaft only needs to place the intermediate shaft assembly 5 on the clamping device 1, position the intermediate shaft support frame with three positioning pins, and then manually clamp it, which can ensure the consistency of each installation. When detecting the first piece and changing the type of workpiece, use a special zero calibration plate to perform zero calibration. To clamp the workpiece, you only need to install the intermediate shaft support frame on the positioning pin to achieve accurate positioning. As shown in Figure 2, slide the probe 2 along the guide rail to cover the end of the intermediate shaft with the oil seal bushing, and press it to the oil seal bush. At this time, the data displayed by the measuring scale 3 connected to the probe 2 is the middle The relative position of the shaft assembly oil seal bushing and the support frame, and the outer diameter detection mechanism 6 of the intermediate shaft can measure the outer diameter of the intermediate shaft at the same time. It can judge whether the product is qualified by directly comparing it with the process or drawing, and manually replace the workpiece to enter the next measurement cycle. Using the checking tool, the detection speed is fast, the method is simple, the error is reduced, and the efficiency is greatly improved.

The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods, as long as various insubstantial improvements are adopted in the method concept and technical solutions of the present invention, or there is no improvement Directly applying the conception and technical solutions of the present invention to other occasions falls within the protection scope of the present invention.
