Abstract

The invention discloses a screw verticality detection device, which comprises a base, a guide rod vertically arranged above the base, and a bearing seat sleeved outside the guide rod, and a linear bearing is arranged inside the bearing seat. The linear bearing is slidingly fitted on the outside of the guide rod, and a first locking wrench is provided on one side of the lower end of the bearing seat, and one end of the first locking wrench passes through a threaded hole to abut against the guide rod, and the One side of the upper end of the bearing seat is provided with a dial indicator and a second locking wrench, the measuring end of the dial indicator is perpendicular to the guide rod, and one end of the second locking wrench passes through the threaded hole to abut against the dial indicator. The guide rod is used as the measuring track of the dial indicator, which ensures the stability of the measurement data. The first locking wrench is used for fixing the bearing seat, and the second locking wrench is used for the dial indicator. Subtable fixation. The invention has the advantages of convenient use, simple operation, high detection precision and low investment cost.

Description

【Technical field】 [0001] The invention relates to the technical field of machining inspection tools, in particular to a screw rod perpendicularity detection device. 【Background technique】 [0002] In mechanical processing, the manifestations of workpiece accuracy mainly include dimensional accuracy, shape accuracy and position accuracy. Dimensional accuracy refers to the accuracy of the size of the surface of the part and the distance between the surfaces; shape accuracy refers to the actual surface of the processed part. The degree of conformity between the measured shape and the ideal shape; position accuracy refers to the degree of conformity between the actual position and the ideal position of the relevant elements of the parts after processing. As one of the position accuracy evaluation criteria, verticality is used to evaluate the vertical state between straight lines, between planes or between straight lines and planes. As a connecting piece commonly used in the man...
