Problems solved by technology

The caliper measurement is to roughly determine the measurement position by visual inspection and then read the reading, which will definitely cause poor repeatability and inaccurate measurement data during measurement, and is not suitable for measurement that requires higher precision; although the three-coordinate measurement method can measure the aperture more accurately , but the operation is complicated and takes a long time, so it is not suitable for the inspection process of mass production of workpieces

Abstract

The invention relates to a width measurement mechanism, which comprises a flange, a push rod, a gauge body, a first measurement rod, elastic blocks and a second measurement rod. Installation grooves are arranged on two lateral sides of the gauge body, the elastic blocks are in slide connection in the installation grooves, the elastic blocks and the gauge body are in clearance fit, an elastic deformation portion and an adhesion measurement ball are arranged on each elastic block, and installation holes are positioned on the elastic blocks. The first measurement rod and the second measurement rod are respectively arranged in the installation holes, the first measurement rod and the second measurement rod are in interference fit with the elastic blocks, an inclined groove is arranged at one end of the first measurement rod, an inclined face is arranged at one end of the second measurement rod, and the inclined face and the inclined groove are used for limiting the push rod. The push rod extends out of the gauge body into the flange, and a limit protrusion is arranged on the portion of the push rod in the flange. The width measurement mechanism is simple and compact in structure, highin measurement accuracy, simple in operation and capable of quickly measuring variation of measured width and enabling measurement equipment to be capable of measuring sizes of higher grades.

Description

technical field [0001] The invention relates to a mechanism for width measurement, in particular to a width measurement mechanism for open gears, and belongs to the technical field of measurement and inspection devices. Background technique [0002] Currently, measuring width is usually done with calipers and coordinate measuring machines. Caliper measurement is to roughly determine the measurement position by visual inspection and then read, which will definitely cause poor repeatability and inaccurate measurement data during measurement, and is not suitable for measurement that requires higher precision; although the three-coordinate measurement method can measure the aperture more accurately , but the operation is complex and time-consuming, so it is not suitable for the inspection process of mass production of workpieces. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a width measuri...
