Problems solved by technology

[0002] The routine process of processing castings is that the fitter draws the line and draws the processing benchmark, and then the machining equipment operator corrects the line and draws the benchmark before processing. Since the usual method of aligning the engraved line is to observe with the eyes, the error is large, and it cannot be compared with the drawing. The state of the line remains highly consistent, resulting in uneven distribution of blanks after part processing
Especially for complex, multi-branched blanks, if there is a deviation in the benchmark, it will have a great impact on the position of each profile, and it is impossible to ensure that the wall thickness is evenly distributed

Embodiment Construction

[0023] The processing method is described in further detail below. The specific parts processing steps are as follows:

[0024] The invention provides an integrated tooling for line drawing and positioning, including a positioning box, a clamping table and a processing base;

[0025] The square box has a cubic shape, with threaded holes on the upper end of the cube and positioning pins; the three-dimensional coordinate system of the square box corresponds to the machining coordinate system of the machine tool, and there is a conversion relationship;

[0026] The clamping table is provided with three adjusting nails arranged in a uniform ring shape. The three adjusting nails are used to support the parts, and the spatial position of the parts can be adjusted by the three adjusting nails; a pressure plate is also provided on the clamping table, so The pressure plate is used to press and fix the parts on the three adjusting nails; the clamping table is provided with positioning holes t...

Abstract

The invention discloses an integral tool for scribing and positioning and a using method thereof. Scribing and machining methods adopted after scribing in the traditional sense are improved, and the method using the scribing and positioning integral tool for rapidly and accurately reaching machining process standards. The method has the advantages that rapid and accurate coordinate conversion fromscribing by a bench worker to machining tool machining is achieved, errors caused by manual aligning scribing are avoided, and the blank machining accuracy is improved.

Description

Technical field [0001] The invention belongs to the field of mechanical processing of shell castings, and relates to an integrated tooling used for line drawing positioning and a use method thereof, and an improvement on the line drawing of the shell and the processing method after drawing the line. Background technique [0002] The conventional step of processing castings is to draw lines by fitters and draw the processing benchmarks, and then the machining equipment operators will correct the drawing benchmarks and then process them. Since the normal method of aligning the markings is to observe with eyes, the error is large and cannot be drawn in harmony. The state of the line is kept highly consistent, resulting in uneven distribution of the blank after the parts are processed. Especially for the complex, multi-branch structure of the blank, if the benchmark has a deviation, the position of each profile will be greatly affected, and the uniform wall thickness distribution can...
