Abstract
The utility model discloses a reproducible milling cutter. The reproducible milling cutter comprises a cutter head, a connecting rod and a shank which are coaxial, wherein the cutter head and the connecting rod are fixed; the connecting rod axially penetrates through the shank; the outer circumferential surface of the connecting rod, along the circumferential direction, is provided with a plurality of clamping strips; the clamping strips extend along the axial direction of the connecting rod to both end surfaces of the connecting rod; the shape of the end surface of each clamping strip is in T type; the inner circumferential surface of the shank, along the circumferential direction, is provided with clamping grooves matched with the clamping strips; the clamping groove extends along the axial direction of the shank to both end surfaces of the shank; the shank, at the end far away from the cutter head, is provided with a radial penetrating hole; the penetrating hole is provided with an internal thread; a locking bolt with an external thread penetrates through the penetrating hole to lock the connecting rod; the internal thread and the external thread are matched with each other. After the locking bolt is loosened, the connecting rod can move axially, the cutter head can shrink, and then, after the position of the cutter head is adjusted, the locking bolt is used for locking. The clamping strips and the clamping grooves are matched with one another, so that circumferential displacement of the cutter head and the shank can be effectively prevented.
Description
Technical field
The utility model relates to renewable milling cutter.
Background technology
The loss of milling cutter is the bigger part of production cost, and milling cutter has to change because of wearing and tearing or breaking.The milling cutter that polishing is scrapped comes into operation again, can effectively reduce production costs, but the length of milling cutter will shorten in the bruting process, causes itself and milling machine not to mate, so be difficult to really realize the re-using of milling cutter.
The utility model content
The purpose of this utility model is to provide a kind of renewable milling cutter, and its cutter head telescopically is installed on the handle of a knife, and the cutter head position can be adjusted vertically, and effectively avoids the circumferential displacement of cutter head and handle of a knife.
For achieving the above object, the technical solution of the utility model is a kind of renewable milling cutter of design, comprises coaxial cutter head, connecting rod and handle of a knife, and cutter head and connecting rod are fixed, and pitman shaft is to running through handle of a knife; The outer peripheral face of connecting rod circumferentially is provided with some card articles along it, card article along pitman shaft to extending to the connecting rod both ends of the surface, the T type that is shaped as of card article end face; The inner peripheral surface of handle of a knife circumferentially is provided with the draw-in groove that matches with card article along it, and draw-in groove extends axially to the handle of a knife both ends of the surface along handle of a knife; Handle of a knife is provided with radially through hole in its end away from cutter head, and through hole is provided with internal thread, and one is with externally threaded clamping screw to run through through hole and lock connecting rod, and internal thread and external screw thread cooperatively interact.
Preferably, described connecting rod is provided with graduation apparatus.
Preferably, the end of described connecting rod is provided with position limiting convex ring.
Preferably, described card article is circumferentially uniform on the outer peripheral face of connecting rod.
Advantage of the present utility model and beneficial effect are: a kind of renewable milling cutter is provided, and its cutter head telescopically is installed on the handle of a knife, and the cutter head position can be adjusted vertically, and effectively avoids the circumferential displacement of cutter head and handle of a knife.
After clamping screw loosened, connecting rod can move axially, and cutter head is scalable; Lock with clamping screw again after the adjustment of cutter head position.Card article and draw-in groove cooperatively interact, and can effectively avoid the circumferential displacement of cutter head and handle of a knife.
Description of drawings
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the schematic diagram of card article and draw-in groove.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
The concrete technical scheme of implementing of the utility model is:
A kind of renewable milling cutter comprises coaxial cutter head 1, connecting rod 2 and handle of a knife 3, and cutter head 1 is fixing with connecting rod 2, and connecting rod 2 axially runs through handle of a knife 3; The outer peripheral face of connecting rod 2 circumferentially is provided with some card articles 4 along it, and card article 4 extends axially to connecting rod 2 both ends of the surface along connecting rod 2, the T type that is shaped as of card article 4 end faces; The inner peripheral surface of handle of a knife 3 circumferentially is provided with the draw-in groove that matches with card article 4 along it, and draw-in groove extends axially to handle of a knife 3 both ends of the surface along handle of a knife 3; Handle of a knife 3 is provided with radially through hole in its end away from cutter head 1, and through hole is provided with internal thread, and one is with externally threaded clamping screw 5 to run through through hole and lock connecting rod 2, and internal thread and external screw thread cooperatively interact.Described connecting rod 2 is provided with graduation apparatus 6.The end of described connecting rod 2 is provided with position limiting convex ring 7.Described card article 4 is circumferentially uniform on the outer peripheral face of connecting rod 2.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
