Multi-purpose height ruler

Abstract

The title of the present invention is a kind of multi-purpose height ruler, relate to a kind of measuring instrument of measuring height and depth. It mainly solves the problem of large-scale workpiece inspection, which requires large-scale measuring instruments and special inspection tooling, which requires a large investment. General measuring tools measure the surrounding dimensions on a certain benchmark, and the measurement range and position are limited. It is not easy to fix during operation and is susceptible to human factors. The problem of interference. One end of the main ruler of the present invention is fixed with a rotating shaft, the rotating shaft is connected to the magnetic base through a roller bearing, the horizontal auxiliary ruler is fixed on the main ruler perpendicular to the main ruler through the ruler frame, and the vertical auxiliary ruler and the horizontal auxiliary ruler are fixed vertically through the ruler frame On the horizontal sub-ruler, measuring claws are fixed at the end of the horizontal sub-ruler. The invention improves the machining efficiency and precision of workpieces.

Description

technical field [0001] The invention relates to a measuring instrument for measuring height and depth, in particular to a multipurpose height gauge for measuring the relative height and depth difference of a plurality of adjacent and spaced planes under the same benchmark. Background technique [0002] At present, in the field of mechanical processing, many large workpieces need to measure the height and depth difference of multiple planes, or need to measure the height value of the relative plane across a certain distance. The relative height and depth dimensions are not easy to determine, and the objects that need to be measured through large-scale measuring instruments and special inspection tooling have the problems of low inspection efficiency and large investment. The general height gauge or depth gauge measures the surrounding dimensions on a certain benchmark. First, the measurement range and position are limited, and it is impossible to measure the size of the inter...

Problems solved by technology

[0002] At present, in the field of mechanical processing, many large workpieces need to measure the height and depth difference of multiple planes, or need to measure the height value of the relative plane across a certain distance. The relative height and depth dimensions are not easy to judge, and the objects that need to be measured through large-scale measuring instruments and special inspection tools have the problems of low inspection efficiency and large investment

The general height gauge or depth gauge measures the surrounding dimensions on a certain benchmark. First, the measurement range and position are limited, and it is impossible to measure the size of the interval plane; second, because the base of the height gauge and the frame of the depth gauge are measuring It needs to be fixed by hand during operation, and the measurement operation is easily disturbed by certain human factors; third, when measuring the height, it is necessary to hold the base of the height gauge tightly by hand, which is not convenient for measurement operation and recording
