In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a measuring tool, including a bottom plate and an insert, the side of the insert is provided with a square groove transversely penetrating the insert, and the square groove is provided with a For measuring the plug gauge of the product, a square positioning platform is provided on the side where the insert is attached to the bottom plate, and the transverse dimension of the positioning platform is consistent with the transverse dimension of the insert. A positioning slot adapted to the positioning platform.

Further, there are two positioning platforms, and the two positioning platforms are respectively arranged at both ends of the insert.

Further, there are two square grooves, and the two square grooves are arranged in parallel between the two positioning platforms.

Further, the opening of the positioning groove is located at the side of the bottom plate, and the positioning groove vertically penetrates through the bottom plate.

Further, the ends of the groove walls on both sides of the positioning groove are provided with guide parts formed by chamfering.

Further, the bottom plate is provided with a positioning hole for positioning the product to be measured.

Further, the insert is fixedly connected to the base plate by screws, and the insert and the base plate are respectively provided with threaded holes matching the screws.

Further, there are two screws and two threaded holes, and the two threaded holes are respectively arranged between the square groove and the two positioning platforms.

Further, the threaded hole on the insert is a countersunk hole.

After adopting above-mentioned technical scheme, the beneficial effect of the utility model is:

A measuring tool of the present invention includes a base plate and an insert. The side of the insert is provided with a square groove that runs through the insert transversely. A plug gauge for measuring products is provided in the square groove. The insert fits the base plate. There is a square positioning platform on one side, the lateral dimension of the positioning platform is consistent with the transverse dimension of the insert, and the positioning groove matching the positioning platform is provided on the bottom plate, the insert can be processed by wire cutting, through a single process And only one clamping can effectively improve the processing dimensional accuracy of a single part, further ensure the tolerance requirements after assembly, and reduce the processing time and improve processing efficiency. Through the cooperation of the positioning table and the positioning groove, the insert can be plugged into the bottom plate together.

Since the opening of the positioning groove is located on the side of the bottom plate, and the positioning groove vertically penetrates the bottom plate, the ends of the groove walls on both sides of the positioning groove are provided with guide parts formed by chamfering, so that the positioning platform can be inserted into the bottom plate from the side, and guide The setting of the center facilitates the insertion of the positioning table into the positioning groove, which can improve work efficiency.

Since the insert is fixedly connected to the base plate by screws, the insert and the base plate are respectively provided with threaded holes matching the screws, which can fix the insert on the base plate and prevent the insert from moving.

In summary, a measuring tool of the present invention replaces two pins on one side with a plug-in method, which effectively improves the processing dimensional accuracy and processing speed of a single part, and ensures the positioning accuracy after assembly.
