A precision hole processing equipment for thin-wall casing parts

Abstract

The invention belongs to the technical field of manufacture of high-end equipment and relates to a precision hole machining apparatus for thin-walled case type parts, comprising an outer bushing; an inner cavity of the outer bushing is filled with an outer height-density sponge board; a case part is mounted in an inner cavity of the outer height-density sponge board; n inner cavity of the case part is filled with an inner high-density sponge board. The hollow structures of a thin-wall case part, the inner cavity of the part and the outside of the part are all fitted with the metal bushing of high rigidity; gaps between are filled with high-density sponge that has good plasticity, high shock resistance and high toughness; therefore, the rigidity of the case part is effectively improved. After the bushing of low cost is provided with a precision hole, a hole can be directly formed by manual drilling and grinding; the demand for high-precision lathes is lowered, the cost demand is lowered, and the production scale is widened. Since the inner and outer bushings are prepared in advance, the problem is avoided that production is completely unable to be carried out once machine tools fail.

Description

technical field [0001] The invention relates to the technical field of high-end equipment manufacturing, in particular to a precision hole processing equipment for thin-wall casing parts. Background technique [0002] In the manufacturing process of aero-engine parts, there are extremely high requirements on the compactness of the parts, especially in the process of opening holes for thin-walled casing parts, because of its thinness and poor rigidity, it is difficult to process , so now in order to ensure the processing accuracy and processing speed, the machine tool with high cost is generally used for processing, but the phenomenon of tool vibration will still cause the deviation of the position of the precision hole, and because of the high cost of the machine tool, the machining of aviation parts will not be completed. It is not universal, and once a processing error occurs in the processing machine tool, the processing process will be directly shut down, causing huge lo...
