A Multi-Size Measuring Tool

Abstract

The invention discloses a multi-size measuring tool, which comprises an upper cover body and a lower cover body. Several measuring parts are installed inside the upper cover body, and a turning handle is fixedly connected to the upper cover body. It can cooperate with the measuring parts, the lower cover is connected with the upper cover in rotation, the measuring part is fixedly connected with the lower cover through the fixed shaft, the conversion of the measuring parts can be realized by the rotation of the lower cover, and the measurement can be realized by the clockwise rotation of the turning handle The screwing of parts and bolts to be measured; the beneficial effect of the present invention is: the measurement of bolts to be measured of different sizes is realized through internal threads of different sizes, which improves the measurement efficiency; only through the rotation of the lower cover to realize the measurement of different sizes The replacement of the measuring nut improves the convenience of replacement; through the cooperation of the measuring nut and the card slot on the rotating handle, and the clockwise rotation of the rotating handle, the measuring nut and the card slot are guaranteed not to be disengaged, and can be connected with the bolt to be measured. External thread measurement improves measurement reliability.

Description

technical field [0001] The invention relates to the field of bolt processing, in particular to a multi-size measuring tool. Background technique [0002] The thread processing of bolts mainly includes turning, washing, tapping, threading and grinding. Among them, turning, washing and grinding are generally used for thread processing of larger bolts, and tapping and threading are generally used for The thread processing of small-sized bolts requires multiple measurements of the bolts during the processing of some bolts to ensure that the processing of the threads can meet the requirements of use. Generally, the larger-sized bolts have a larger tolerance range due to their processing , so it is enough to use a conventional caliper to measure, but some small-sized bolts have a small tolerance range for thread processing, and the conventional caliper measurement is very inaccurate, and there may be multiple sizes of bolts that need to be processed during general processing. , s...
