A processing method for parts with multiple non-processing surfaces

Abstract

The invention discloses a machining method for a part with multiple unfinished surfaces. The machining method comprises the steps of making of a line-carving locating template and part machining. In part machining, firstly, the made line-carving locating template is placed on a plane of the part, a visual observation method is used for enabling an oil groove contour line of the line-carving locating template to be aligned with the oil groove contour edge of the part, and a clamping device is used for clamping the line-carving locating template on the part; then a cushion plate is mounted on a machine tool work table, the part, the line-carving locating template and the clamping device are arranged on the cushion plate together, the mounting position of the part is adjusted well, the part is well pressed by a pressing plate avoiding the line-carving locating template, and locating blocks are mounted; and finally, the clamping device is loosened and taken down with the line-carving locating template, and therefore the part can be machined. The line-carving locating template is used for quickly and accurately finding the unfinished surfaces, and product quality is improved; the scribing process is omitted, labor intensity of workers is reduced, and therefore the machining cycle is shortened, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a processing method for casting parts, in particular to a processing method for parts containing a plurality of non-processing surfaces, and is especially suitable for applications where there are many non-processing surfaces and the gap between the processing surface and the non-processing surface The valve body and shell parts that require a higher distance between them. Background technique [0002] For casting parts, especially valve body parts, multiple non-machined surfaces are based on the center of the same machined hole (or the same machined plane). In order to ensure the distance between the processing surface (hole center or plane) and multiple non-processing surfaces during processing, it is necessary to process the non-processing surface as a benchmark. When the casting precision is low, it is now necessary for the fitter to mark the line, one by one to ...

AI Technical Summary

Problems solved by technology

If the non-processed surface is a curved surface, it is difficult to find the curved surface when marking, which makes the marking inaccurate

And the more non-processed surfaces, the greater the workload of scribing, and the lower the accuracy

The oil hole, oil groove, etc. between the butt joint surfaces of the parts are caused by inaccurate butt joints, which affects the quality of the product
