Description
Technical field
The present invention relates to Machining Technology field, a kind of frock processing circular hole on inclined-plane and processing method thereof.
Background technology
In the course of processing of various parts, it is often necessary to process circular hole on inclined-plane.Owing to processing contact angle the on-right angle of circular hole, drill bit and machined surface on inclined-plane, this just brings impact to the regular feed of drill bit.Prior art generally uses various clamp for machining working position carries out accommodating protection, thus improve stability when bit is holed.But, during drill bit with processing contact of incline plane, owing to being non-perpendicular contact, drill bit can produce uneven extruding and destruction to the edge of circular hole, affects the crudy of circular hole.The processing method that Chinese invention patent CN 101745662B discloses a kind of inclined hole, an end face vertical with direction of feed is first processed at machined surface, thus improve machining accuracy, but this processing mode needs to carry out workpiece single end face processing, need to use single milling machine to be processed, in order to ensure the crudy of end face, long processing time, causing the man-hour needed for processing circular hole on inclined-plane longer, working (machining) efficiency cannot improve further.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of frock processing circular hole on inclined-plane and processing method thereof, it is possible to solve the deficiencies in the prior art, improves the quality processing circular hole on inclined-plane.
For solving above-mentioned technical problem, the technical solution used in the present invention is as follows.
A kind of frock processing circular hole on inclined-plane, it is characterised in that: include,
Being fixed on the cushion block on processing inclined-plane, cushion block be arranged in parallel with processing inclined-plane with the medial surface of processing contact of incline plane, and the lateral surface of cushion block is vertically arranged, and cushion block is welded with the block of two horizontal directions with processing on the medial surface of contact of incline plane；
For the clamping device that cushion block is fixed together with processing inclined-plane；
For processing the first drill bit of circular hole, the top of the first drill bit is provided with the first tapered portion, and the sidewall of the first drill bit is provided with spiral first cutting groove；
For processing the second drill bit of circular hole, the top of the second drill bit is provided with the second tapered portion, the sidewalls vertical of the second drill bit is provided with three the second cutting grooves, the sidewall of the second drill bit is provided with spiral 3rd cutting groove, second cutting groove and the 3rd cutting groove are interconnected, and the external diameter of the second drill bit is more than the external diameter of the first drill bit.
As preferably, the thickness of described cushion block is 1:4 with the ratio of the degree of depth of made circular hole.
As preferably, the distance of said two block inner side edge is less than the external diameter of the first drill bit, and the distance of said two block outer side edges is more than the external diameter of the first drill bit, less than the external diameter of the second drill bit.
As preferably, the degree of depth of described first cutting groove is 2:9 with the ratio of the first outside diameter.
As preferably, described second cutting groove, the degree of depth of the 3rd cutting groove are 2:1:7 with the ratio of the external diameter of the second drill bit.
As preferably, the outside of described first tapered portion is provided with a lobe, and the top of lobe is provided with skewed slot, and skewed slot is 25 ° with the angle of vertical direction.
A kind of processing method using the above-mentioned frock processing circular hole on inclined-plane, comprises the following steps:
A, using milling cutter to process two shrinkage pools on processing inclined-plane, inserted by block in corresponding shrinkage pool so that cushion block closely cooperates with processing inclined-plane, then processing inclined-plane is fixed by use clamping device with cushion block；
B, use the first drill bit to drill through cushion block, processing inclined-plane gets out a groove；
C, use the groove that the second drill bit gets out in step B centered by again hole, the second drill bit gets out regulation in processing inclined-plane and requires the circular hole of the degree of depth；
D, take off clamping device, cushion block is separated with processing inclined-plane, obtain the circular hole processed on processing inclined-plane.
As preferably, in step B, first drill bit feeding rate when not in contact with processing inclined-plane is more than the feeding rate after the first bit contact processing inclined-plane.
As preferably, in step C, the second drill bit, after touching processing inclined-plane, uses feed forward and the mode that withdrawing replaces backward to feed, and each depth of cut is more than withdrawing amount.
What employing technique scheme was brought has the beneficial effects that: the present invention produces guide effect by utilizing cushion block, it is to avoid produce when drill bit and processing contact of incline plane rocks.Block is divided into twice cutting in twice boring, can also ensure that while the direction of feed of firm drill bit the second drill bit is not directly contacted with the lateral surface on processing inclined-plane, thus avoid, when the second drill bit is with processing contact of incline plane, the outward flange processing circular hole is produced extruding and destroy.First first drill bit drills through a less pit on processing inclined-plane, and then the second drill bit carries out further feed boring in the path drilled through along the first drill bit, and circular hole is made the most at last.First drill bit and the preferred parameter of the second drill bit and structure can ensure the synchronicity of twice boring procedure effectively, and the second drill bit can reduce the extruding to circular hole sidewall and top in boring working angles to be destroyed.Lobe can make the first drill bit form a groove tilted on processing inclined-plane, and this can make the second drill bit first pass through groove and the second bit contact when with processing contact of incline plane, thus reduces the extruding force that the second drill bit contacts with the outer edge of circular hole.Second drill bit uses the bore mode of piston motion type to hole, the cutting precision for circular-hole internal-wall can be improved, thus can suitably reduce feeding pressure on the premise of ensureing processing request, thus reduce second drill bit pressurization destructive power for circular hole outer edge.
