0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; precision jig processing is usually a single piece manufacturing, and the manufacturing cycle is very short, in order to ensure the processing of the workpiece Begging, many fixtures must have a higher manufacturing accuracy. The tool workshop of the enterprise has a variety of processing equipment, such as coordinate boring machines for processing hole systems, universal milling machines for processing complex shapes, fine lathes and various grinding machines, etc., all of which have good machinability and processing accuracy. In the manufacturing of fixtures, in addition to the different consumption methods from ordinary products, there are certain restrictions on the application of interchangeable guidelines to ensure the accuracy of the manufacture of fixtures.
The design of the processing technology of precision jigs and fixtures is an important technical work in mechanical processing, and a reasonable mechanical processing technology is an important link to ensure the processing accuracy of parts and improve the efficiency of labor consumption. Therefore, it is necessary technical work for the manufacture of fixtures to formulate the specifications for the machining process of fixture parts.
The request of processing technology design for precision jigs
1, the machining accuracy of the parts should be guaranteed, and all technical requirements proposed on the design drawings should be reached;
2, on the premise of ensuring the processing accuracy, try to improve the consumption rate and reduce the cost;
3 To reduce the labor intensity of workers as much as possible, it is necessary to think about safety and industrial hygiene;
4, make full use of the existing consumption conditions to formulate the manufacturing process of fixtures.
