What are the selection of positioning datums for precision parts processing?
The production of nuts, studs, and stainless steel materials is becoming more and more intelligent now. When producing these equipment accessories, choose accurate and high-standard equipment. With the advancement of science and technology, intelligent and automated instruments , The equipment has a very fast speed in the circulation of various fields, which brings challenges and opportunities in a new stage to the development of precision parts. This paper analyzes the market demand and process concept of precision parts, and combines the skills and problems in actual processing (with the scope of clamp work as the limit), and explores the solutions and skills of related problems in precision parts processing in order to improve precision parts. Improve the quality of market supply and demand, and promote the development of a technological and intelligent society.
In actual production, the structure of each part may be very different, which also greatly increases the difficulty of processing. However, if you observe carefully, you can find that the basic geometric composition of parts is nothing more than outer circle, inner hole, plane, thread, tooth surface, curved surface, etc., so as long as the processing of these shapes is mastered, the difficulty of precision parts processing is also Can be greatly reduced.
In the process of precision parts processing, whether the selection of positioning reference is reasonable or not determines the quality of the parts, and it is very important to ensure the dimensional accuracy and mutual position accuracy of the parts, as well as the arrangement of the processing sequence between the surfaces of the parts. Big impact. If the fixture is used to install the workpiece, the choice of positioning datum will also affect the complexity of the fixture structure. Therefore, the choice of positioning datum is a very important process problem in precision parts processing.
Nowadays, mechanized and automated production has been achieved in part of the production process. Then the automated processing system can automatically monitor its operating status, and automatically adjust its parameters when subjected to external interference or internal excitation to achieve the best state and availability. Self-organization ability, so as to greatly improve the efficiency of rough and finishing processing under the premise of ensuring processing accuracy.
