Abstract
The utility model discloses an inner hole slotting tool, which includes a cutter head, a centering screw, a cutter handle, a centering taper hole, a positioning flat surface and a positioning keyway; the positioning flat surface is formed at one end of cutter head, and the cutter handle is provided with the positioning keyway corresponding to the positioning flat surface, and the centering taper hole is formed at the other end of cutter head, and the centering screw penetrates the centering taper hole to connect the cutter head and the cutter handle. The inner hole slotting tool provided by the utility model has simple and reliable structure. Different cutter heads can be designed according to different groove width of parts. The cutter head and the cutter handle can be disassembled and connected through the centering screw, so that different types of cutter heads can be quickly and accurately replaced, thus according to the utility model, only different cutter heads need to be made, to save the purchase cost of the cutting tool, and improve work efficiency.
Description
Technical field
The utility model relates to a kind of machine tools, is a kind of endoporus slotting tool specifically.
Background technology
In machining, many hydraulic quick coupler class parts are arranged, the shallow straight trough that is parallel to the center, hole is arranged in its endoporus, all adopt in the past wire cutting machine tool or spark-erosion machine tool processing, long processing time, productivity ratio is low, and processing cost is high, is not suitable for producing in enormous quantities.Appearance along with CNC Turning Center lathe and machining center, can adopt the processing mode of slotting to realize its processing, but different groove widths need different slotting tools to process, and needs to change back and forth slotting tool in process, reduce operating efficiency, increased the cost of buying cutter.
The utility model content
Goal of the invention: for the problem and shortage of above-mentioned existing existence, the purpose of this utility model is to provide a kind of simple, reliable, the endoporus slotting tool that can reduce purchase cost and increase work efficiency.
Technical scheme: a kind of endoporus slotting tool comprises slotting tool cutter head, centering screw, slotting tool handle of a knife, the taper hole of feeling relieved, locates flat and positioning spline; The flat face in described location is opened the end at the slotting tool cutter head, described slotting tool handle of a knife is provided with and locates flat corresponding positioning spline, described centering taper hole is opened the other end at the slotting tool cutter head, and described centering screw runs through the centering taper hole slotting tool cutter head and slotting tool handle of a knife are linked together.
As preferably, the tail end of described dog screw is provided with the centering conical surface corresponding with the taper hole of feeling relieved.
As preferably, described slotting tool cutter head adopts high-speed steel to make.
Beneficial effect: compared with prior art, the utlity model has following advantage: the utility model is simple in structure, reliable, groove width that can be different according to part designs different slotting tool cutter heads, slotting tool cutter head and slotting tool handle of a knife can be dismantled connection by centering screw, can be quick, change accurately dissimilar slotting tool cutter head, so the utility model only need be made different slotting tool cutter heads and gets final product, both save the purchase cost of cutter, improved again operating efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model slotting tool cutter head structure schematic diagram;
The left view that Fig. 3 is Fig. 2;
Fig. 4 is the utility model slotting tool Knife handle structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Referring to figs. 1 through Fig. 4, a kind of endoporus slotting tool, comprise slotting tool cutter head 1, centering screw 2, slotting tool handle of a knife 3, centering taper hole 4, locate flat 5 and positioning spline 6; Locate an end of opening for flat 5 at slotting tool cutter head 1, slotting tool handle of a knife 3 is provided with and locates flat 5 corresponding positioning splines 6, centering taper hole 4 is opened the other end at slotting tool cutter head 1, and centering screw 2 runs through centering taper hole 4 slotting tool cutter head 1 and slotting tool handle of a knife 3 are linked together.
As preferably, the tail end of dog screw 2 is provided with the centering conical surface corresponding with the taper hole 4 of feeling relieved.
As preferably, slotting tool cutter head 1 adopts high-speed steel to make.
Adopt technique scheme, slotting tool cutter head and slotting tool handle of a knife are fixed together by centering screw.Locate flat face and be stuck in positioning spline the orientation that realizes the slotting tool cutter head, the orientational cone-shaped surface that centering screw is provided with coordinates and realizes that slotting tool cutter head center is coaxial with slotting tool handle of a knife center with the centering taper hole, thereby can realize quickly and easily changing the slotting tool cutter head, increase work efficiency.The slotting tool cutter head adopts high-speed steel to make, and the slotting tool handle of a knife adopts general structural steel to make, and saves the cutter purchase cost.
The foregoing is only better embodiment of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; in every case the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or is changed, and all should include in the protection domain of putting down in writing in claims.
