Parallelism detection device

Abstract

The invention discloses a parallelism detection device, belonging to the technical field of parts error detection. The parallelism detection device comprises a measuring head, a scale, a connecting plate and a bridge plate. The measuring head contacts a left bus of a lead screw, and a locking screw is arranged below the measuring head. When being positioned, the measuring head is locked by the locking screw. The measurement surface of the scale contacts an upper bus of the lead screw, and a vernier digital display ruler sleeves the rod part of the scale. The parallelism error between the upper bus of the lead screw and a bed way is read out by the vernier digital display ruler. The vernier digital display ruler and the bridge plate are connected via the connecting plate and a screw. During detection, the whole device can move along the axial direction of the lead screw, so that the parallelism between the whole axial direction of the lead screw and the bed way can be detected. The parallelism detection device designed by the invention is simple to manufacture and convenient to use, is of high measurement precision, and can detect the parallelism errors between the upper and side buses of the longitudinal lead screw and the surface of the bed way simultaneously.

Description

technical field [0001] The invention relates to the technical field of component error detection, in particular to a parallelism detection device. Background technique [0002] With the development of the machinery industry, the requirements for the shape and position error of the parts are getting higher and higher. Therefore, various detection tools for the shape and position errors of the parts appear on the machine. When the detection elements on the parts increase, the traditional The detection equipment often needs to detect different elements separately, which will be a waste of time. In addition, after the traditional detection equipment determines the reference plane, it usually causes problems such as the coordination error between the reference elements of the device itself and the workpiece reference. increase in error. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that multiple elements on the part need to b...
