Description
Technical field
the utility model relates to a kind of cutter for machined grooves in elongated tubular, belongs to Machining Technology field.
Background technology
in the processing of large graduated cylinder (pipe) class part, stepped hole or groove many employings Boring in hole.But some part, length and aperture than l/d > 10 time to process difficulty of getting up very large.Boring cutter bar is a cantilever beam from amechanical angle.Boring groove in darker elongated hole, or large outer little multi-stage stairs hole in processing in hole, be difficult to the dimensional accuracy and the roughness that ensure bore hole.Because when needing the degree of depth of bore hole dark and collar extension aperture is less again, common boring cutter bar is much smaller than aperture, boring cutter bar has just become an elongated cantilever beam, and rigidity is obviously not enough, and causing boring the hole one come is that distal dimension that knife bar flexure bores hole can diminish and is difficult to ensure dimensional accuracy; Two is that when cutting, knife bar extremely easily produces the roughness trembleed and be difficult to ensure to bore hole.
Utility model content
the purpose of this utility model is, provides a kind of cutter for machined grooves in elongated tubular, to improve the machining accuracy of elongated tubular inner groovy, thus overcomes the deficiencies in the prior art.
the technical solution of the utility model is achieved in that
a kind of cutter for bore hole in elongated tubular or machined grooves of the present utility model is that this cutter comprises knife bar, and knife bar is tubular structure; Knife bar front end is provided with cutter head, cutter head and knife bar hinged; Be provided with push rod in knife bar, knife bar end is provided with nut, and nut is threaded with knife bar.
in aforementioned cutter, described knife bar front end is provided with cutter relieving groove, cutter head distribution and knife bar front end hinged.
in aforementioned cutter, be provided with push rod in described knife bar, knife bar end is provided with nut, and nut is threaded with knife bar; Nut one end is closed.
in aforementioned cutter, the cylindrical of described knife bar is provided with clamping face.
in aforementioned cutter, the front end of described cutter head is cutting end, and cutting end is outside; The end of cutter head is inclined-plane.
compared with prior art, the utility model, by the improvement to cutter, achieves the maximization of knife bar size, reduces deflection deformation and the vibration of knife bar in process, improve the machining accuracy of elongated tubular inner groovy.Have pin-and-hole above boring cutter, cutter head can rotate around pin; The cutter head of bore hole not by screws clamp, and utilizes the thrust of push rod that cutter head is tightened up; Axial advance and the spiral exited by screw thread of push rod convert axially-movable to; On general lathe, bore hole is knife rest clamping knife bar bore hole from outside to inside, and knife bar is in being subject to curved state, and knife bar of the present utility model is from inside to outside pull when bore hole, and can reduce cutter vibration of bar, bore hole quality is better.

Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
the utility model is constructed by the method for following a kind of machined grooves in elongated tubular, as shown in Figure 1, the steel pipe that the method adopts external diameter to be slightly less than elongated tubular internal diameter is less than processed elongated tubular internal diameter 0.5 ~ 3 millimeter as the outer diameter of steel pipes diameter of knife bar 4 under normal conditions as knife bar 4(), knife bar front end is provided with rotation blade; Before processing, cutter head corner β is adjusted to clip horn shape state, makes cutter head 2 can enter elongated tubular (see figure 2) from the elongated tubular mouth of pipe smoothly; Add man-hour, then cutter head corner β is adjusted to cutting angle, then when elongated tubular 8 rotates, knife bar is drawn from inside to outside, cut required groove by cutter head 2 at elongated tubular 8 inwall.Cutter head corner β is the angle between cutter head and knife bar axis.Knife bar front end is provided with cutter relieving groove 6, and cutter head distribution 1 is hinged with the cutter relieving groove of knife bar front end, and cutter head is that fulcrum rotates in cutter relieving groove with pin.Be provided with push rod 3 in knife bar, knife bar end is provided with nut 5, promotes cutter head and rotates counterclockwise, realize the adjustment of the little angle of cutter head corner β to cutting angle by rotating nut by push rod.Elongated tubular is clamped on the claw of lathe, drives elongated tubular to rotate by claw; Arbor holder is held on the knife rest of lathe, drives knife bar rectilinear motion from inside to outside by knife rest, adopts the traditional method of indicating the pronunciation of a Chinese character to cut the processing of groove.
the of the present utility model a kind of cutter for bore hole in elongated tubular or machined grooves built as stated above, as shown in Figure 3: this cutter comprises knife bar 4, knife bar 4 is tubular structure; Knife bar 4 front end is provided with cutter head 2, and cutter head 2 is hinged with knife bar 4; Be provided with push rod 3 in knife bar 4, knife bar 4 end is provided with nut 5, and nut 5 is threaded with knife bar 4.Knife bar 4 front end is provided with cutter relieving groove 6, and cutter head 2 distribution 1 is hinged with knife bar 4 front end, and can rotate in cutter relieving groove 6.In knife bar 4, be provided with push rod 3, knife bar 4 end is provided with nut 5, and nut 5 is threaded with knife bar 4; Nut 5 one end is closed.The cylindrical of knife bar 4 is provided with clamping face 7.The front end of cutter head 2 is cutting end, and cutting end is outside; The end of cutter head 2 is inclined-plane.
the course of work of the present utility model and principle further illustrate as follows:
dotted portion in Fig. 1 in elongated tubular 8 part is position to be processed.Specifically adding man-hour, as seen from Figure 1, elongated tubular 8 left end aperture major part can be processed with common knife bar, but arrived dotted line position, because hole is excessively dark, knife bar must lengthen along with hole depth, but rigidity wretched insufficiency after knife bar lengthens, so common knife bar cannot be adopted to continue bore hole.Adopt cutter of the present utility model, can avoid entering to process from left end endoporus, also just solve the long problem brought of knife bar.Knife bar is entered from right-hand member aperture, and the drawback of entering from aperture is exactly that hole is little, and knife bar and boring cutter must be less than aperture and just can enter.With cutter head on knife bar, the cutting edge of cutter head generally will stretch out certain cantilever and just can cut from knife bar, endoporus can be entered smoothly to make cutter head, and the inwall of macropore can also be cut to, segment design is rotary type cutter head by the utility model, when entering endoporus, as shown in Figure 2, first move cutter head to dotted line orientation, enter after inner hole of workpiece is positioned at working position until knife bar entirety, pass through rotating nut, top pressure push rod is moved to the left, push rod pushes cutter head and slowly rotates counterclockwise cutting angle, push against after cutter head until push rod, cutter head just forms certain cantilever, just can boring endoporus.Trial cut can be started after cutter head must be made during boring to be pushed against completely to cut.
