Embodiment Construction

[0068] Taking the processing of the workpiece of the double-wing plunger seat as an example and referring to the accompanying drawings, the processing method based on the active positioning and position memory installation system of the present invention will be described in detail.

[0069] (1) Analysis of processing objects: (see Figure 3) It can be seen from the working drawing and design requirements of the double-wing insert rod seat that the workpiece has poor rigidity and is not α- and β-symmetrical, and its main processing features are the upper and lower end faces, holes, and the upper and lower sides of the wings. and its surrounding contours. The material of the workpiece is 45 steel, and its relevant design dimensions are shown in Table 2. The roughness (Ra) of all processed surfaces is required to be 1.6 μm.

[0070] (2) Blank design: According to the design requirements and process characteristics, the profile is selected as the blank of the double-wing inserting...

Abstract

The machining method based on active location and position memory mounting system is mainly characterized by that said method includes the following steps: adopting standard location box to blank to be machined and make the blank face with arbitrary shape; adopting filler state of restore memory position so as to make the original mounting position of workpiece in the arbitrarily-changed procedure conversion do not produce change; based on the original mounting reference of workpiece and coordinate conversion method calculating procedure coordinate parameter and making digital control machining program. The workpiece blank is placed into location box, accurately positioned by using location element and fastening element, the filler is injected and the original mounting position of the workpiece can be defined, then can be machined according to the defined procedure.

Description

technical field [0001] The invention relates to workpiece processing, in particular to a processing method based on an active positioning and position memory installation system. Background technique [0002] Statistics show that: in single-piece small-batch production, the product production preparation cycle accounts for more than 50% of the total production cycle, and the fixture cost in the manufacturing cost is as high as 15%, while the utilization rate of CNC processing equipment is lower than 50%. The direct consequences of long production lead times, high fixture costs and low equipment utilization are: [0003] (1) Limiting the rapid response of manufacturing enterprises to market demand; [0004] (2) Violating the basic requirements for the implementation of lean production; [0005] (3) It restricts the imagination and creativity of designers for new product development. [0006] In 1972, Coes.L invented a clamping device for irregular workpieces in its publish...
