Description
Technical field
The utility model relates to a kind of boring machine instrument, especially relates to a kind of boring machine instrument that can process taper hole.
Background technology
Boring machine in mechanical processing industry be use one of lathe the most widely.The boring machine instrument mainly is made up of boring bar and the boring cutter that is used to cut, and the rear end of boring bar links to each other with boring spindle, and the front end of boring bar is equipped with cutting tool, when boring spindle rotates and moves forward, promptly can be used to the processing equipment part.During common boring machine tool processes cylindrical hole part, its machining accuracy and efficient all are very high.But during with common boring machine tool processes conical bore part, situation is just completely contradicted.What the processing conical bore adopted usually is forming-tool, and promptly conical reamer is referring to accompanying drawing 2.The more conventional cutter of cutting edge of conical reamer 2 ' of being shaped wants wide a lot, and the tapering that cutting edge forms during boring bar 3 ' rotation is consistent with the tapering of part to be processed 1 '.Jia Gong taper hole length is longer if desired, the conical reamer 2 ' that is shaped adds and often needs " connecing cutter " man-hour, be the length of sectional processing with the assurance taper hole, because the conical reamer cutting edge that is shaped is longer, therefore the be shaped conical reamer depth of cut and cutting speed are all very little in addition.The conical reamer processing taper hole that is shaped can only be used for roughing, reach the requirement of drawing dimensional accuracy and roughness, also need with the higher circular cone reamer fine finishining of precision, like this, with common boring machine tool processes taper hole have that cutting output is few, cutting speed is slow, poor, the time taking shortcoming of machining accuracy.
The utility model content
Technical problem to be solved in the utility model is the boring machine instrument that a kind of machining accuracy height, fireballing processing taper hole are provided at above-mentioned prior art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the boring machine instrument of this processing taper hole, comprise the boring bar that the rear end is connected with boring spindle, the front end of boring bar is equipped with boring cutter, it is characterized in that: the front end of described boring bar is fixed with a cylinder head, there is an angle between the longitudinal center line of this cylinder head and the longitudinal center line of described boring bar, the size of this angle is 1/2 of a part to be processed taper angle, offer a slotted hole on the described cylinder head, the length of this slotted hole is greater than the length of part to be processed taper hole; Be equipped with one on the described cylinder head and can described boring cutter be installed on this knife rest sliding sleeve along cylinder head knife rest sliding sleeve in axial sliding.
As improvement, described boring bar is a hollow stem, and its central shaft is to being a through hole, and in the center axially extending bore of boring bar extension bar is installed, the rear end of this extension bar links to each other with described boring spindle, the middle-end of extension bar be contained in the lining of boring bar central shaft on through-hole wall and match; The front end of extension bar is equipped with the push rod of trough of belt, and the spring washer of locking purposes is housed between the leading section of push rod and extension bar, and cam pin is contained on the knife rest sliding sleeve by the slot part of push rod, and matches with slotted hole on the cylinder head.
Compared with prior art, advantage of the present utility model is: by using the utility model structure, when boring spindle rotates, can drive boring bar with the speed rotation, when boring spindle stretches out, promote knife rest sliding sleeve and boring cutter to front slide, because boring bar nose circle cylinder head has certain gradient, the knife rest sliding sleeve drives boring cutter and regains with gradient, and bore hole can be more and more littler.In like manner, during the boring spindle withdrawal, boring cutter can stretch out gradually, and bore hole can be increasing.The gradient of the gradient of taper hole and cylinder head axes is identical, because the cutting speed of cutter and cutting output are identical with cutter on the common logical boring bar, therefore, the machining accuracy of part and processing progress have obtained effective assurance.
Description of drawings
The structural representation of the boring machine instrument of the processing taper hole that Fig. 1 provides for the utility model embodiment;
Fig. 2 be among Fig. 1 A-A to cutaway view;
Fig. 3 is the structural representation of the boring machine instrument of processing taper hole in the prior art;
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Process the boring machine instrument of taper hole as illustrated in fig. 1 and 2, comprise boring bar 8, boring bar 8 is a hollow stem, its central shaft is to being a through hole, the front end of boring bar 8 is fixed with a cylinder head 81, has an angle between the longitudinal center line of the longitudinal center line of cylinder head 81 and boring bar 8, and the size of this angle is 1/2 of part to be processed 1 taper angle, cylinder head 81 offers slotted hole 82, and the length of this slotted hole 82 is greater than the length of part to be processed 1 taper hole; Be equipped with one on the cylinder head 81 and can boring cutter 4 be installed on this knife rest sliding sleeve 2 along cylinder head 81 knife rest sliding sleeve 2 in axial sliding, the rear end of boring bar 8 is connected on the facing head 16 of boring machine by screw 9, adpting flange 10, screw 17.In the center axially extending bore of boring bar 8 extension bar 12 is installed, the rear end of this extension bar 12 with straight pin 13 by Mohs 5 extra cones 14 and link to each other with boring spindle 15, the middle-end of extension bar 12 be contained in the lining 11 of boring bar 8 central shafts on through-hole wall and match; The front end of extension bar 12 is equipped with the push rod 5 of trough of belt, and the spring washer 6 of locking purposes is housed between the leading section of push rod 5 and extension bar 12, and cam pin 3 is contained on the knife rest sliding sleeve 2 by the slot part 51 of push rod 5, and matches with slotted hole 82 on the cylinder head 81.
When boring machine facing head 16, main shaft 15 rotations, can drive whole device with the speed rotation, when boring spindle 15 stretches out, push rod 12 promotes knife rest sliding sleeves 2 and boring cutter 4 to front slide by cam pin 3, because the cylinder head 81 of boring bar front end has certain gradient, knife rest sliding sleeve 2 drives boring cutter 4 and regains with gradient, and bore hole can be more and more littler.In like manner, during main shaft 15 withdrawals, boring cutter 4 can stretch out gradually, and bore hole can be increasing.The gradient of taper hole and the gradient of cylinder axis are identical, because the cutting speed of cutter and cutting output are identical with cutter on the common logical boring bar, therefore, the machining accuracy of part and processing progress have obtained effective assurance.
