Abstract
Positioning, which is crossed, the utility model discloses a kind of axial tightening side tightens interchangeable drill body, including drill body and cutter head, both ends perforation is set as an installation through-hole in drill body, by being threadedly engaged connection between the drill body and cutter head, the rear end of cutter head is integrally formed with a dextrorotation external screw thread connecting rod, the levogyrate inner thread set with dextrorotation external screw thread connecting rod matching thread connection is provided in installation through-hole, levogyrate inner thread, which is covered, is set as a thrust inclined-plane close to one end of cutter head, the thrust screw that inner face presses against on the thrust inclined-plane is provided on drill body, thrust screw is obliquely installed；It is vertically arranged between the thrust screw and thrust inclined-plane；The utility model has the beneficial effects that practical, production cost is low, and structure novel is connected firmly, it is ensured that will not loosen between drill body and cutter head, stability is more preferable.
Description
Technical field
The utility model relates to a kind of boring component, in particular to a kind of axial tightening side cross positioning tighten it is interchangeable
Drill body.
Background technique
Currently, the not no drill body of similar structures on the market.
Utility model content
Technical problem to be solved in the utility model is in view of the deficiencies of the prior art, to provide a kind of axial tightening side
It crosses positioning and tightens interchangeable drill body.
To achieve the goals above, the measure that the utility model is taken:
A kind of axial tightening side crosses positioning and tightens interchangeable drill body, including drill body and cutter head, both ends in drill body
Perforation is set as an installation through-hole, by being threadedly engaged connection, the rear end one of cutter head between the drill body and cutter head
A dextrorotation external screw thread connecting rod is formed, is provided in installation through-hole and dextrorotation external screw thread connecting rod matching thread connection
Levogyrate inner thread set, levogyrate inner thread is covered to be set as a thrust inclined-plane, being provided with inner end on drill body close to one end of cutter head
Face presses against the thrust screw on the thrust inclined-plane, and thrust screw is obliquely installed；
It is vertically arranged between the thrust screw and thrust inclined-plane.
The utility model has the beneficial effects that practical, production cost is low, and structure novel is connected firmly, it is ensured that drill body and knife
It will not be loosened between head, stability is more preferable.
Detailed description of the invention
Fig. 1 is the planar structure schematic diagram of the utility model.
Specific embodiment
A kind of axial tightening side crosses positioning and tightens interchangeable drill body, including drill body 1 and cutter head 2, two in drill body 1
End perforation is set as an installation through-hole 1-1, by being threadedly engaged connection between the drill body 1 and cutter head 2, cutter head 2
Rear end in dextrorotation external screw thread a connecting rod 2-1, installation through-hole 1-1 integrally formed with being provided with and dextrorotation external screw thread connecting rod
The levogyrate inner thread set 3 of 2-1 matching thread connection, levogyrate inner thread set 3 are set as a thrust close to one end of cutter head 2
Inclined-plane 3-1, the thrust screw 4 that inner face presses against on thrust inclined-plane 3-1 is provided on drill body 1, and the inclination of thrust screw 4 is set
It sets.
Firstly, levogyrate inner thread set 3 is packed into installation through-hole 1-1, then dextrorotation external screw thread connecting rod 2-1 is passed through into screw thread
Be connected on levogyrate inner thread set 3, be finally screwed into thrust screw 4 on drill body 1, the inner face of thrust screw 4 with it is left-handed interior
Thrust inclined-plane 3-1 contact on thread bush 3, and drive levogyrate inner thread set 3 to mobile, the levogyrate inner thread far from 2 side of cutter head
3 band dynamic cutter head 2 of set moves together, and cutter head 2 is close to drill body 1, finally makes the outer end face of drill body 1 and the inner face of cutter head 2
It is in close contact completely, the loosening of the two in use can be effectively prevent.
It is vertically arranged between the thrust screw 4 and thrust inclined-plane 3-1.
