The auxiliary device for fixing the main grating ruler and the scale housing of the grating scale belongs to the field of photoelectric measurement technology. In order to solve the problem of low installation accuracy when fixing the main grating scale and the scale housing of the grating scale in the prior art, the positioning base of the scale housing is positioned and fixed On the high platform of the base; the linear motion mechanism is fixed on the low platform of the base; the fast pressing mechanism is fixed on the positioning base of the scale shell, the lower end of the fast pressing mechanism is in contact with the scale shell, and the scale is pressed or loosened by a wrench. shell; the auxiliary positioning mechanism of the main grating scale is fixed on the connecting plate, and is connected with the main grating scale, and is used for auxiliary positioning and pressing of the main grating scale; the positioning of the connecting plate is installed on the linear motion mechanism, and the cylindrical elastic body pressing mechanism is fixed on the On the connecting plate, the linear motion mechanism drives the cylindrical elastic body press-in mechanism to move through the connecting plate, and presses the cylindrical elastic body between the scale shell and the main grating scale to realize the fixing of the main grating scale and the scale shell. The cylindrical elastic body is installed accurately and is suitable for mass production.
Description
technical field [0001] The invention relates to an auxiliary device for fixing a grating ruler main grating ruler and a ruler shell, and belongs to the technical field of photoelectric measurement. Background technique [0002] In the field of precision measurement and position control, the use of grating ruler as a reference is internationally recognized as the most practical, economical and reliable technical measure to obtain high precision. The grating ruler measuring mechanism is a representative product to achieve this approach, and is widely used in various machine tools, electromechanical equipment, and automated measuring equipment. [0003] There are many ways to install and fix the main grating and the scale housing of the grating ruler. One of the more common methods is to place the main grating against the mounting surface in the scale housing, and then press the long cylindrical elastic body into its designed position. , so that the elastic body is compressed ...
