Abstract

The invention relates to an assembling device of a grating ruler carriage and bearings and an assembling method of the assembling device, and belongs to the technical field of photoelectric measurement. A thread and a guiding structure are adopted, and the pressing speed and the pressing depth of cylindrical pins can be stably, slowly and accurately controlled. The bearings are limited in the axial direction through an inserting piece with the thickness equal to the difference of the width of carriage bearing holes and the width of the bearings, and the problem that when carrying out limiting, the inserting piece is frequently damaged since the inserting piece is too thin is greatly solved. A magnet is used for limiting and fixing the cylindrical pins, and the problems that the manual clamping position of the cylindrical pins is not accurate, and the cylindrical pins are prone to falling or even losing are solved. Accurate positioning can be achieved for the carriage, the bearings and the cylindrical pins. The cylindrical pins are pressed two times in one direction, a large load is achieved one time, a minus load is achieved at the other time, it is guaranteed that the cylindrical pins are pressed in place in one direction, and the reliability of matching of the cylindrical pins and pin holes in the carriage is greatly improved. Meanwhile, the assembling device is simple in structure, convenient to operate and high in assembling efficiency.
