Description
The utility model is a kind of dedicated tool that is used for the pore grooving, especially a kind of special-purpose cutting tool of grooving on the hole wall optional position that is using on the drilling machine.
To carrying out grooving processing in the pore, specific purpose tool must be arranged at present, however the general more complicated all of existing various specific purpose tool, and the requirement on machining accuracy height of cutter own, make difficulty, especially knife bar and blade row must cooperate making.Mainly contain the defective of following three aspects in the use.
1. knife bar and cutter must cooperate makings, first kind of situation be cutter to lean on two its gradients of inclined-plane be to slide mutually between 1: 10 inclined-plane to carry out feed, the subject matter of this cutter is relatively difficulties of two inclined-planes processing, the necessary unanimity of the gradient on inclined-plane.Cutting knife is around bearing pin swing feed on the other hand, and myopia is thought translation, and the annular groove end face can not be vertical with the hole inwall, influences the precision of paddle-tumble.As be published in " pressure vessel " March nineteen ninety, " tube sheet grooving specific purpose tool " by name is exactly typical case's representative of this kind cutter.Second kind is that cutting knife and core bar also must cooperate making, the processing gradient is 1: 10 a diagonal bar on core bar, also process the groove that matches with diagonal bar on the cutting knife, sliding on the core bar diagonal bar by cutting knife produces radial motion, the realization feed, above both of these case except make cumbersome, after using a period of time, cutting blade abrasion is changed cutting knife and is bothered very much, and influences paddle-tumble position dimension precision.
2. the complex structure of cutter, length is long, and in the working angles, drill press spindle produces vibration and causes rocking arm to swing back and forth, and not only noise is big, and after using a period of time, influences the precision of drilling machine.
3. cutting knife cutting force is reflected on core bar or the inclined-plane fully, is easy to make the distortion of core bar or inclined-plane, has so just limited the width of paddle-tumble in aperture.
Goal of the invention of the present utility model just provides a kind of simple in structure, reliable, easy accessibility, vibrationless substantially pore grooving dedicated tool.
Pore grooving specific purpose tool of the present utility model is by drilling rod, upper holder block, spring, lower lock block, jackscrew a, eccentric bushing, jackscrew b, plane bearing, positioning sleeve, cutting knife, the top screw rod, knife bar, gland is formed, wherein by eccentric bushing, plane bearing, positioning sleeve, gland is formed the cutter box, in the drilling rod is hollow cylindrical, knife bar is through in the mesopore of eccentric bushing, knife bar and eccentric bushing are arranged in the hole of drilling rod jointly, between the end of the end of knife bar and drill pipe bore, also be provided with lower lock block and upper holder block, between this two briquetting, be provided with spring, also be provided with the jackscrew b of fixing eccentric bushing and the fixing jackscrew a of knife bar in the side of drilling rod, on knife bar, also be provided with positioning sleeve, between positioning sleeve and eccentric bushing, be provided with plane bearing, gland is pushed down positioning sleeve and is fixed on the eccentric bushing, and cutting knife is positioned at the front end of knife bar to be fixed by the top screw rod.The middle part of drilling rod is provided with a helicla flute, and the angle of this helicla flute and drill rod axis is 45 °, and the end of jackscrew a is arranged in this groove.The outside of eccentric bushing is provided with keyway along axis direction, and the front end of jackscrew b is arranged in this groove.During work, work as drilling rod, the cutter box inserts in the pore, fix the position of paddle-tumble by positioning sleeve, drill press spindle drive drilling rod rotatablely moves on the one hand then, axial feed passes to lower lock block by upper holder block compression spring on the one hand, compressing knife bar axial feed, after putting in place, along with the axial feed of drilling rod, knife bar rotates in eccentric bushing, drives cutter and carry out length feed on the relevant position, cutter head incision tube sheet, jackscrew a moves in the drilling rod helicla flute, produces angle, determines the cutter head length feed degree of depth, finish the paddle-tumble process, along with drilling machine is axially gone up motion, under spring action, jackscrew a, jackscrew b slides in drilling rod helicla flute and eccentric bushing keyway respectively, drive the cutter box and return original position, finish withdrawing.
Advantage of the present utility model is:
1. simple in structure, reliable, easy accessibility.Cutter and knife bar separate machined have reduced production cost, have improved operating efficiency.
2. owing to adopted plane bearing in the cutter box, eliminated the vibration that the drilling machine axle is produced fully, therefore work is more reliable.
3. can once mark the wide expanded tube hole groove of 1～12mm in pore 18～ 800mm, the degree of depth of its groove is in 2 millimeters.
Fig. 1 is a general structure schematic diagram of the present utility model.Comprising drilling rod 1, upper holder block 2, spring 3, lower lock block 4, jackscrew a5, eccentric bushing 6, jackscrew b7, plane bearing 8, positioning sleeve 9, cutting knife 10, top screw rod 11, knife bar 12, gland 13.
Fig. 2 is the structural representation of drilling rod.Helicla flute 1-1 is wherein arranged.
Fig. 3 is the structural representation of eccentric bushing, and keyway 6-1 is wherein arranged.
Fig. 4 is the structural representation of knife bar, and jackscrew a5 and top screw rod 11 are wherein arranged.
Embodiment of the present utility model is as follows.
The outside of drilling rod 1 is taper, and inside is hollow cylindric, and outside one end of drilling rod and the drill bit fixed cover of drilling machine match.Form the cutter box by eccentric bushing 6, plane bearing 8, positioning sleeve 9, gland 13, knife bar 12 passes this cutter box, one of knife bar 12 is arranged in the endoporus of drilling rod jointly with an end of eccentric bushing, on the lateral wall of eccentric bushing, be provided with a keyway 6-1, be provided with a little screw on the drilling rod wall, jackscrew b just is spun in the little screw on the drilling rod, and the front end of its jackscrew b is positioned at the keyway of eccentric bushing, therefore eccentric bushing can endwisely slip, and the scope of its slip is in the length of keyway.In drill pipe bore, be provided with jackscrew a on one of knife bar, the outer end of this jackscrew a is arranged in the helicla flute on the drilling rod sidewall, the angle of the direction of this spiral fluted direction and drill rod axis is 45 °, and jackscrew a can slide in the helicla flute on drilling rod, rotates thereby drive knife bar.Between the termination of the termination of drill pipe bore and knife bar, be provided with upper holder block 2 and lower lock block 4, between two briquettings, be provided with spring 3.The middle part of knife bar is arranged in the cutter box, its two is positioned at outside the cutter box, also is provided with positioning sleeve 9 outside the knife bar of eccentric bushing front end, is provided with a plane bearing between positioning sleeve and eccentric bushing, positioning sleeve is pushed down in the end of gland 13, and the medial surface of gland is fixed on the eccentric bushing by screw thread.Cutting knife is positioned at outer knife bar one end of cutter box, by top screw rod fixed cutting tool.Just can form pore grooving specific purpose tool of the present utility model according to the above.
