Problems solved by technology

The actual assembly process used in the enterprise factory is also pure manual assembly, because the structure of the carriage is complex, the structure of the carriage and the bearing is too compact, and the operation process is very inconvenient, so the quality of the assembly is random and the consistency is poor

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0021] like figure 1 As shown, in the grating ruler carriage and bearing assembly device, the grating ruler carriage 10, the first bearing 101, the second bearing 102, the third bearing 103, the fourth bearing 104 and the fifth The bearing 105 has the same structure as the five bearings 101-105. The diameter of the outer ring of the bearing is 4mm, the diameter of the inner ring is 1.5mm, and the width is 2mm; the width of the bearing hole K103 corresponding to the third bearing 103 on the grating slider 10 is 2.5mm, and the diameter of the pin hole XK103 is 1.5mm.

[0022] like figure 2 As shown, the grating ruler carriage and bearing assembly device is composed of a working position turntable 20 , a first press-in mechanism 30 , a second press-in mechanism 40 , a third press-in mechanism 50 , a fourth press-in mechanism 60 , and an insert...

Abstract

The assembly device and assembly method of the grating ruler carriage and the bearing and the assembly method thereof belong to the field of photoelectric measurement technology. The invention adopts a screw thread and a guide structure, and can control the press-in speed and the press-in depth of the cylindrical pin smoothly, slowly and accurately; the carriage bearing is adopted The difference between the hole width and the bearing width The thickness of the insert can limit the bearing in the axial direction, which greatly improves the problem that the insert is often damaged because the thickness is too thin; the magnet is used as the limit of the cylindrical pin, The fixing method solves the problem that the artificial clamping position of the cylindrical pin is not accurate, and it is easy to drop or even lose; whether it is the carriage, bearing or the cylindrical pin, it can be accurately positioned, and the cylindrical pin is pressed in twice in one direction. One is a large amount of feed, and one time is a small amount of feed, which ensures that the cylindrical pin is pressed into place in one direction, which greatly improves the reliability of the cooperation between the cylindrical pin and the pin hole on the carriage. At the same time, the device of the invention has simple structure, convenient operation and high assembly efficiency.

Description

technical field [0001] The invention belongs to the technical field of photoelectric measurement, and in particular relates to an assembly device and an assembly method of a grating ruler carriage and a bearing. Background technique [0002] In the field of precision measurement and displacement control, the grating ruler is often used as a closed-loop measurement method. The grating ruler is also recognized as the most economical and applicable technical equipment for high-precision measurement, so it is widely used in engineering technology fields involving measurement such as machine tools and displacement consoles. [0003] The assembly of the reading head of the grating scale is an important process in the manufacturing process of the grating scale. The assembly of the carriage and the bearing in this assembly is the basis of the assembly of the reading head. The carriage structure in the reading head of the grating scale is complex, and the bearing size to be assemble...
