Precise clamp used for micro-miniature complex thin-walled part machining and control method of precise clamp

Abstract

The invention discloses a precise clamp used for micro-miniature complex thin-walled part machining and a control method of the precise clamp. According to the core part of the mechanical structure of the precise clamp, five gas-liquid damping cylinders connected through universal joints are adopted for the upper end and five gas-liquid damping cylinders connected through universal joints are adopted for the lower end, and therefore a platform which can rise, fall and deflect can rise and fall by 0-80 mm and deflect by 0-270 degrees according to the machining and processing requirements of thin-walled parts and can be suspended in any space and keep the required posture according to requirements, and a whole workpiece can be machined on a composite machine tool through one-time clamping; in addition, by arranging a visual system, visual and accurate machining information is provided when the micro-miniature complex thin-walled parts are machined by operators; industrial personal computer centralized control is adopted for the control method of the precise clamp, the control scheme is simple and reasonable, and the precise clamp and the control method have the advantages that the automation degree is high, control is convenient and efficient under the man-machine synergistic effect, and the precise clamp and the control method are suitable for machining micro-miniature thin-walled structural pieces with various three-dimensional complex morphologies or free-form surfaces.

Description

technical field [0001] The invention relates to a precision fixture for micro machine tool processing and a control method thereof, in particular to a precision fixture and a control method for processing micro-miniature complex thin-walled parts, and belongs to the technical field of meso / micro cross-scale processing. Background technique [0002] During the processing of micro-miniature parts, it needs to be frequently grasped during the process conversion between machine tools. Due to the small overall structure and size of micro-miniature parts, they are easy to be lost or damaged; and because of their small functional surfaces, re- Positioning and clamping are unreliable and easy to deform. In the light case, the machining accuracy will be lost, and in the severe case, the parts will be scrapped. [0003] In particular, for precision micro-sized structural parts with complex structures, small linear scales, many processing procedures, and high precision requirements, th...

Problems solved by technology

[0002] During the processing of micro-miniature parts, it needs to be frequently grasped during the process conversion between machine tools. Due to the small overall structure and size of micro-miniature parts, they are easy to be lost or damaged; and because of their small functional surfaces, re- Positioning and clamping are unreliable and easily deformed, which may cause loss of machining accuracy in light cases, or lead to scrapping of parts in severe cases

[0003] In particular, for precision micro-sized structural parts with complex structures, small linear scales, many processing procedures, and high precision requirements, the traditional distributed process method is used to process on multiple machine tools and multiple clamping and positioning, which often cannot guarantee the processing. Quality, some parts have a very low processing pass rate and processing efficiency
