Tool and method for measuring lengths of workpieces

Abstract

The invention discloses a tool and a method for measuring the lengths of workpieces. The technical scheme mainly includes that the tool comprises a base; positioning components and a graduated scale are arranged on the base, an accommodating groove is formed in the base, the graduated scale is connected into the accommodating groove in a lifting manner, lifting blocks which are higher than the surface of the base are connected onto the base in a lifting manner, linkage mechanisms are arranged on the lifting blocks, and the graduated scale can be subjected to linkage to upwardly move when the lifting blocks downwardly move. The tool and the method have the advantages that the graduated scale is stored in the accommodating groove when the to-be-measured workpieces are not arranged on the base, accordingly, protection effects can be realized, and abrasion of the surface of the graduated scale can be reduced; the to-be-measured workpieces can be arranged on the base during measurement, can be positioned by the aid of the positioning components and are compressed on the lifting blocks at the moment, the lifting blocks can be driven to downwardly move, accordingly, the graduated scale can be subjected to linkage to upwardly move, the lengths of the to-be-measured workpieces can be measured, the to-be-measured workpieces are light, cannot drive the lifting blocks to completely downwardly move in the periods and can be manually further downwardly compressed, and the lifting blocks and the graduated scale can be restored to return the normal positions after the lengths of the to-be-measured workpieces are measured and the to-be-measured workpieces are removed.

Description

technical field [0001] The invention relates to the field of workpiece measurement, in particular to a tool for measuring the length of a workpiece and a measuring method thereof. Background technique [0002] In the process of building construction, many workpieces are needed, and the length of the workpieces needs to be measured to check whether they meet the requirements of the corresponding specifications. The existing measuring tools include bases and scales fixed on the bases. When in use, the workpiece to be measured is placed on the base, and then it is measured with the scale. Since the scale is fixed on the surface of the base, the scale on the surface will wear out during long-term use, resulting in Difficult to take accurate readings later. Contents of the invention [0003] The purpose of the present invention is to provide a measuring tool for workpiece length, which can effectively reduce the wear of the scale, and can be used more permanently and read accu...
