Abstract
The utility model relates to a cutter head used to fix turning tools, and is characterized in that three location holes are opened in a clamping chuck, the direction of one of the location holes is parallel to the axial direction of the cutter head, and in addition, the other two holes forms 45 DEG oblique angles to the axial direction of the cutter head. Tool sleeves are arranged in the location holes, and the tool sleeves are fixed in the location holes by bolts, which are used to planish and chamfer end heads of steel tubes on tube end flatting machines. The three tool are all plain blades and can be interchanged.
Description
The utility model belongs on lathe the parts that fixing lathe tool is used.
Be to improve pipe quality, require before steel pipe dispatches from the factory its termination tied with chamfered edge and handle.A kind of cutterhead that uses has been introduced in No. 88217075 patent application in our factory on facing-machine, it is to fix three flat blade cutters by cross locating slot and bolt type cutter holder on two sides of chuck, wherein one the direction of cutter and cutterhead axially parallel, be used for tack, in addition two cuttves and cutter axis be to becoming 45 to spend oblique angles, is used for chamfered edge.It is more suitable that this cutterhead is used for handling the steel pipe of bore more than two cun and two cun, to the tubule of bore below two cun, when settling side by side owing to two chamfered edge cuttves, is subjected to the restriction of cutter holder bolt nut, and cutter can not lean on very closely, so be unwell to the steel pipe of processing below two cun.
The purpose of this utility model is a kind of cutterhead of handling the steel tube head of diameter below two cun that is exclusively used in of design.
Design of the present utility model is that three cutter holders are made up of broach shell and a fastening bolt that a side has a tool bore respectively; Offer three locating holes with the chuck parallel sided in chuck, the bore of locating hole and the external diameter of broach shell match, and the direction of locating hole is, the axially parallel of one of them center line and cutterhead, and two center lines and cutterhead axial becomes an oblique angle in addition; Side perpendicular to chuck has the screw that leads to locating hole, screws in above-mentioned fastening bolt in this screw.
For general steel pipe, above-mentioned and cutter axis are to two locating holes of bevel, and this oblique angle is 45 degree.Consider the easy to process of these two locating holes, the end face of chuck can be processed into and on center line one side direction, bend to 45 degree.Thereby make locating hole vertical with card.
Accompanying drawing is depicted as embodiment of the present utility model.
Fig. 1 is a front view of the present utility model;
Fig. 2 is that Fig. 1 is along the A-A cutaway view;
Fig. 3 is the schematic diagram of broach shell;
Fig. 4 is the assembly drawing of cutterhead and cutter.
Among the figure: the 1-chuck, the 2-fastening bolt, the vertebra handle that 3-and chuck fuse, tail end are square, be used for fixing on chamfering machine, the cylindrical broach shell of 4-, a side has tool bore 5,6-locating hole, 7-cutter, 8-steel pipe.
The assemble method of cutterhead and lathe tool is inserted broach shell respectively in the locating hole earlier with reference to Fig. 4, is screwed into fastening bolt, and cutter is inserted along the broach shell tool bore, aims at steel tube head, mixes up the extension elongation of cutter, tights a bolt, and cutter promptly is fixed.
The cutterhead that provides with the utility model, beating that cutter that rib uses is reliable for two must be nearer, thereby can process small-caliber steel pipe. This cutter head structure is simple, and three are flat sword to cutter, can exchange, can be as required only with wherein one or two, the working (machining) efficiency height.
Claims (3)
1, the cutterhead of forming by cutter holder and chuck (1), it is characterized in that three cutter holders are made up of a broach shell (4) and a fastening bolt (2) that a side has tool bore (5) respectively, in chuck (1), have three locating holes (6) with the chuck parallel sided, the bore of this locating hole and the external diameter of broach shell match, the center line of one of them locating hole and the axially parallel of cutterhead, in addition the center line of two locating holes and cutterhead axial becomes an oblique angle; Side perpendicular to chuck has the screw that leads to locating hole, inserts above-mentioned fastening bolt in this screw.
As the said cutterhead of claim 1, it is characterized in that 2, the center line of said two locating holes is 45 degree with the axial oblique angle that becomes of cutterhead.
As the said cutterhead of claim 1, it is characterized in that 3, the end face of said chuck is crooked 45 degree on center line one side direction.
