Measuring devices, bisector vernier caliper

Abstract

This final thesis is about a mechanical measuring device that demonstrates its importance in industrial workshops and other engineering venues. It has also been developed into one of the most important mechanical measurement devices in an industrial workshop. Vernier Calliper Bisector was designed to get a cost-efficient and high speed measurement. device for a laboratory. There is no need with this device to use an expensive and complex turning machine as measurement tools determine circular centres, provide very good accuracy and high-performance measurement methods. The main purpose of this device was to develop the ordinary Vernier calliper to be able to measure a circular centre and symmetrical conical axes as well as to find out distances between cones, as well as the possibility to find the head angle of a cone and cone a stem. The device consists of a transmission, two racks and pinions, a fixed jaw, a movable jaw and a bisector jaw. Any party interested in manufacturing, can be considered as a potential customer for the product produced in this project, such as factories, companies, industrial workshops, laboratories, universities, and even hobbyists. The used methods on this thesis were comparing the aspects and functions of measurement devices specifically traditional a vernier caliper and marker the vernier caliper beside defining their components and mechanisms. The main result of this study was merging traditional vernier caliper with the marker vernier caliper to become a bisector vernier caliper which could solve technical problems in a workshop and save time money and effort.
