Detailed Description
The utility model is further illustrated by the following examples:
example 1
The embodiment discloses special measuring tool for locomotive connecting rod, its structure is as shown in fig. 1-6, including base member 1, spiral micrometer 2 and set up first benchmark limiting plate 3, second benchmark limiting plate 4 and third benchmark limiting plate 5 in base member 1 one side, base member 1 is the frame that forms by the reinforcing bar welding, frame length is greater than the locomotive connecting rod length that awaits measuring, and the base member is the structure, can guarantee that its used repeatedly can not warp.
The first reference limiting plate 3 and the second reference limiting plate 4 are arranged at one end of the base body 1, and the third reference limiting plate 5 is arranged at the other end of the base body 1; the inner contours of the first reference limiting plate 3 and the second reference limiting plate 4 are matched with the outer contour of the locomotive connecting rod to be detected, and are used for limiting the big head end of the locomotive connecting rod to be detected; the first reference limiting plate 3 is provided with a hollowed handle, so that the special measuring tool for the locomotive connecting rod can be conveniently moved and used. And a limiting surface is arranged on one side of the first reference limiting plate 3, which is close to the connecting rod of the locomotive to be tested, and is parallel to the connecting rod of the locomotive to be tested, and limits the height direction of the connecting rod of the locomotive to be tested.
