The specific embodiment
For those skilled in the art can understand technical scheme provided by the present invention better, set forth below in conjunction with specific embodiment.
See also Fig. 1-Figure 12, Fig. 1 is the structural representation of the knife bar of the shaped device of sidewall internal taper hole in the embodiment of the invention; Fig. 2 be knife bar among Fig. 1 the latch leading portion A-A to the cross section structure sketch map; Fig. 3 be knife bar among Fig. 1 the latch back segment B-B to the cross section structure sketch map; Fig. 4 is the tool structures sketch map of the shaped device of sidewall internal taper hole in the embodiment of the invention; Fig. 5 is the plan structure sketch map of the cutter of the shaped device of sidewall internal taper hole in the embodiment of the invention; Fig. 6 is the cutter tooth cross section structure sketch map of cutter among Fig. 4; Fig. 7 is the knife bar of the shaped device of sidewall internal taper hole in the embodiment of the invention and a kind of syndeton sketch map of cutter; Fig. 8 is the knife bar of the shaped device of sidewall internal taper hole in the embodiment of the invention and the another kind of syndeton sketch map of cutter; Fig. 9 be Fig. 7 with Fig. 8 in the C-C of knife bar when being connected with cutter to the cross section structure sketch map; Figure 10 is the structural representation of the shaped device of sidewall internal taper hole that positioning ring is installed in the embodiment of the invention; Figure 11 is the state diagram that the shaped device cutter of sidewall internal taper hole in the embodiment of the invention is connected with knife bar; Figure 12 is drilled with the structural representation of the workpiece of internal taper hole for sidewall in the embodiment of the invention.
The shaped device of the sidewall internal taper hole that present embodiment provides comprises cutter 2 and knife bar 1, and cutter 2 is a pyramidal structure; Cutter 2 surfaces are provided with cutter tooth 22; Cutter 2 is connected with knife bar 1 bolt-type, and an end of knife bar 1 is provided with latch, and the middle part of cutter 2 is provided with latch through hole 21.
Wherein, knife bar 1 adopts the 40Cr steel to process, and quenching hardness is 40-45HRC.The latch of knife bar 1 comprises latch leading portion 11 and latch back segment 12,1/4 circular arc of two cubic relative angles of the circumferential cross-section of latch leading portion 11 for equating, and the in addition relative both sides of the circumferential cross-section of latch leading portion 11 are flat side; The circumferential cross-section of latch back segment 12 is flat square structure; The bossing of the axial cross section of the circumferential cross-section of latch leading portion 11 and latch back segment 12 interlaces.
See also 7 and Fig. 8, knife bar 1 has two kinds of connected modes with cutter 2, can be used to process difform internal taper hole 61.
When knife bar 1 is connected with cutter 2, earlier knife bar 1 is inserted in the latch through hole 21 of cutter 2, is rotated in the forward 90 ° of knife bars then, the A face of the latch back segment 12 of knife bar 1 is overlapped with the B face of the latch through hole 21 of cutter 2, knife bar 1 and cutter 2 are screwed at this moment.See also Fig. 9, the figure on this figure left side is that knife bar has just inserted sectional view in the cutter; The figure on this figure the right looks the sectional view behind the knife bar half-twist.
For the degree of depth of the internal taper hole 61 of controlling processing, knife bar 1 is provided with positioning ring 3, and positioning ring 3 is socketed on the body of rod of knife bar 1 and is fixing through screw 4.
The process of the shaped device of the sidewall internal taper hole that present embodiment provides is following:
In the process of sidewall internal taper hole 61, knife bar 1 is packed on the main shaft of common vertical drill, again knife bar 1 is inserted in the main aperture of workpiece 6; Utilize loading and unloading handle 5 that cutter 2 is inserted in the knife bar 1, be rotated in the forward 90 ° of knife bars, can cutter 2 be screwed; Remove loading and unloading handle 5 this moment, start vertical drill and downfeed process boring, in the process of processing boring, need if it were not in main aperture, blowing; Iron filings are blown down; When positioning ring 3 touched the inwall of main aperture, the degree of depth of processing boring put in place, will load and unload handle 5 after the completion again and insert in the fixing hole 23 of cutter; Reverse rotation knife bar 1 also firmly can be removed cutter 2 downwards, and profit uses the same method and reprocesses other sidewall internal taper hole 61.The time spent of an internal taper hole of processing is 0.8 hour, has improved working (machining) efficiency.
Through actual processing test shows; The shaped device of the sidewall internal taper hole that present embodiment provides is after the taper hole processing through 1 workpiece; The cutter tooth of cutter has slight wearing and tearing; Attrition value VB has only 0.04, when the attrition value VB of cutter reaches 0.15, has just needed reconditioning, and reconditioning once can be processed 5 workpiece.Infer that according to the tooth depth of cutter tooth one can process 20-25 workpiece to cutter, the loss of saving process tool through reconditioning repeatedly.
In addition; Because internal taper hole is on the inwall of main aperture, conventional measurer can't directly detect, and therefore must use special-purpose test measuring device; Test measuring device is the same with the cutter connected mode with the connection and the knife bar of knife bar, test measuring device is packed into just can measure in the knife bar.Through detecting, the conical surface of the internal taper hole of processing can reach the requirement of product design, and roughness is below 3.2.
Compared with prior art; The shaped device of sidewall internal taper hole provided by the invention; Cutter and knife bar adopt the mode of rotation latch to lock, and load and unload quick and conveniently, have solved the technical barrier that main aperture and sidewall internal taper hole adopt conventional drilling equipment to process; Greatly improve the working (machining) efficiency of internal taper hole, and can practice thrift processing cost.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments among this paper.Therefore, the present invention will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
