Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings of the description.

[0017] A measuring tool for sheet metal parts, comprising a caliper 1 with scales, a slider 2, a fixing device 4, and a positioning ruler 3, the slider 2 can slide left and right on the caliper 1, and the positioning ruler 3 is rotatable through the fixing device 4 Mounted on slider 2.

[0018] The use method of the present invention is: when measuring a sheet metal part, put the part between the caliper 1 and the positioning ruler 3, slide the slider 2, and rotate the fixing device 4 so that the positioning ruler 3 is completely attached to the flange of the part, and read At this time, the value A of the caliper scale is the value of the width dimension L1 of the part.

[0019] In order to make more full use of the slider 2, the slider 2 is also provided with a guide groove, the fixing device 4 is installed in the guide groove, and can s...

Abstract

The invention relates to a metal plate part size measurement tool. The tool comprises a caliper (1) with scales, a slide block (2), a fixing device (4) and a positioning rule (3). The slide block (2) can slide left and right on the caliper (1). The positioning rule (3) can be rotatably installed on the slide block (2) through the fixing device (4). The metal plate part size measurement tool can be designed into multiple specifications. The structure is simple, manufacturing cost is low, wide versatility is possessed, measuring efficiency is high and accuracy is high too.

Description

technical field [0001] The invention relates to a measuring tool, in particular to a tool for simply and quickly measuring the space theoretical dimension of a sheet metal part. Background technique [0002] For the width of the sheet metal part whose bending angle α is not 90°, additional figure 1 The two widths in , dimensions L1 and L2, where L1 is the theoretical dimension of the space, which cannot be measured by existing measuring tools. In order to measure the above-mentioned theoretical dimensions of the space, it is necessary to improve the existing measurement tools. Contents of the invention [0003] Aiming at the shortcomings of existing devices, the present invention provides a dimension measuring tool for sheet metal parts capable of measuring the aforementioned L1 dimension. [0004] The technical problem to be solved by the invention is to improve a measuring tool with simple structure, convenient operation and high measuring efficiency. [0005] The tec...
