Abstract
The invention discloses a method for processing a waist-shaped hole with high processing efficiency and long service life of a milling cutter. The process comprises the following steps: a, firstly drilling a hole in the central part of the waist-shaped hole by a drill bit; b, beginning plunge milling at the drilled central part by an end milling cutter, then transversely shifting to one side in a distance smaller than the radius of the milling cutter, and carrying out plunge milling downwards again to one side of the waist-shaped hole; c, beginning plunge milling at the drilled central part by the end milling cutter, then transversely shifting to the other side in a distance smaller than the radius of the milling cutter, and carrying out plunge milling downwards again to one side of the waist-shaped hole; and d, finally using the side edge of the end milling cutter to transversely mill and finely finish metal residues. A tool bore previously drilled by the drill bit can avoid the end edge of the central part of the milling cutter participating in cutting and avoid the milling cutter being abraded quickly. By controlling the side direction of the milling cutter, the participation of the end edge of the central part in cutting is avoided, and various adverse factors on the cutter are avoided, so the service life of the cutter is greatly improved, and the cutter has low cost and good economical efficiency.
Description
Technical field
The invention belongs to the processing method in Machining Technology field, particularly a kind of mounting hole.
Background technology
In recent years, from the viewpoint of environmental protection, require the engine for automobile high performance, oil consumption raising, emission abatement.Thereby the high power outputization of engine and high-temp combustionization carried forward vigorously, and rises but the thing followed is an EGT, and exhaust system part is heated repeatedly, cools off in higher humidity province.Under higher temperature conditions, the heat expansion of part and contraction will be more obvious, change the stress that produces in order to compensate the accessory size that occurs that expands with heat and contract with cold, and the bolt hole of the adpting flange face of part changes waist-shaped hole into by circle.
And the processing of waist-shaped hole common two kinds of methods are arranged: the one, process at one time with the slotting cutter side edge on the work in-process heart equipment, specifically, milling under the side direction is milled downwards always and is worn the part flange, finishes processing from horizontal the milling to opposite side of a side.Use the slotting cutter layered milling on the another kind of work in-process heart equipment, specifically be with slotting cutter under a side direction, mill a layer depth, on one deck, the horizontal opposite side that mills, one deck has milled, following one deck is processed, up to finishing.First method adds that man-hour slotting cutter cutting-in is bigger, and the amount of feeding is very little, and influence such as vibration, workpiece deformation makes slotting cutter be easy to fracture failure.Second kind of processing method adds man-hour because of layered milling, and processing route is elongated, main use remain the side edge milling, the processing vibration is big, speed is still lower, cutter is prone to spring sword phenomenon.Working (machining) efficiency is lower, and cutter life is low, use cost is high, is not suitable for parts batch production.
Summary of the invention
The invention provides the processing method of the mounting hole of a kind of working (machining) efficiency height, milling cutter long service life.
A kind of processing method of mounting hole, it may further comprise the steps:
A. the mounting hole centre boring of setting on metallic plate with drill bit earlier;
B. begin from drilled in centre to insert with slotting cutter and mill, traversing to a side then less than the milling cutter radius distance, insert downwards once more and mill to waist-shaped hole one side;
C. begin from drilled in centre to insert with slotting cutter and mill, traversing to opposite side then less than the milling cutter radius distance, insert downwards once more and mill to waist-shaped hole one side;
D. last metal in mounting hole remains less when residual, mills refine with the slotting cutter side edge is horizontal, finishes waist-shaped hole and processes.
The present invention can avoid milling cutter centre end sword to participate in cutting by drill bit following tool bore in advance, avoids the quick loss of milling cutter.Control milling cutter side direction bite avoids centre end sword to participate in cutting less than tool radius; Calculate to insert the number of times of milling cutter at the waist-shaped hole length direction, guarantee residual height suitable more among a small circle, reduce the side milling surplus.With the commonsense method ratio, because milling the mode of inserting, this method under the prerequisite that guarantees cutter safety, do not need to increase the path, from actual processing result, efficient can improve more than three times, to the waist-shaped hole of stock size, process time is about 30 seconds, owing to avoided unfavorable factor everywhere to cutter by the processing of this process, as the end tooth centre do not stress, stressed less serious tremble etc. of avoiding producing of side edge, make cutter life greatly improve, the cost of charp tool is lower, good economy performance.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further.
Fig. 1 is the schematic diagram of the processing method process of mounting hole of the present invention.
The specific embodiment:
As shown in Figure 1,
A kind of processing method of mounting hole, it may further comprise the steps:
A. the mounting hole centre boring of setting on metallic plate with drill bit earlier;
B. begin from drilled in centre to insert with slotting cutter and mill, traversing to a side then less than the milling cutter radius distance, insert downwards once more and mill to waist-shaped hole one side;
C. begin from drilled in centre to insert with slotting cutter and mill, traversing to opposite side then less than the milling cutter radius distance, insert downwards once more and mill to waist-shaped hole one side;
D. last metal in mounting hole remains less when residual, mills refine with the slotting cutter side edge is horizontal, finishes waist-shaped hole and processes.
The present invention can avoid milling cutter centre end sword to participate in cutting by drill bit following tool bore in advance, avoids the quick loss of milling cutter.Control milling cutter side direction bite avoids centre end sword to participate in cutting less than tool radius; Calculate to insert the number of times of milling cutter at the waist-shaped hole length direction, guarantee residual height suitable more among a small circle, reduce the side milling surplus.With the commonsense method ratio, because milling the mode of inserting, this method under the prerequisite that guarantees cutter safety, do not need to increase the path, from actual processing result, efficient can improve more than three times, to the waist-shaped hole of stock size, process time is about 30 seconds, owing to avoided unfavorable factor everywhere to cutter by the processing of this process, as the end tooth centre do not stress, stressed less serious tremble etc. of avoiding producing of side edge, make cutter life greatly improve, the cost of charp tool is lower, good economy performance.
