Description
Technical Field
The utility model relates to a milling cutter technical field specifically is a multiple-cutting-edge thread milling cutter.
Background
A milling cutter is a drilling and cutting tool for metal machining, usually made of cemented carbide, and is a common machining aid for the metal industry.
Most of the bottom ends of the existing thread milling cutters are designed to be smooth, the thread milling cutters cannot be used, and the thread milling cutters can be replaced to be used only after other cutters are used for completing hole opening, so that the machining efficiency is influenced, and the use cost of the cutters is increased. Aiming at the problems, the novel thread milling cutter is innovatively designed on the basis of the original thread milling cutter.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a multiple-cutting-edge thread milling cutter to solve its bottom of the current thread milling cutter who proposes in the above-mentioned background art and do not possess the trompil function for leveling the design mostly, only can utilize other cutters to accomplish just can to change thread milling cutter and use after the trompil, influence machining efficiency and increased cutter use cost's problem.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a multiple-cutting-edge thread milling cutter, includes tool bit, thread groove and construction bolt, the thread groove has been seted up on the tool bit, and the below of tool bit installs the blade, be provided with construction bolt on the blade, and the blade passes through construction bolt and tool bit interconnect to be provided with the edge of a knife on the blade, the drilling head is installed to the lower extreme of tool bit, and the overhead trompil groove of having seted up of drilling.
Preferably, the blades are distributed at equal angles below the cutter head, and the length of the knife edge on each blade exceeds the edge position of the thread groove.
Preferably, the drilling head and the cutter head are of an integrated structure, and the drilling head is of a circular truncated cone-shaped structure.
Preferably, the open cell slots are equiangularly distributed on the drilling head, and the right side edge of the open cell slot is a sharp cutting structure.
Compared with the prior art, the beneficial effects of the utility model are that: the multi-edge thread milling cutter is provided with a cutter head,
1. the bottom end of the cutter head can be used for drilling and cutting, so that the hole is conveniently formed, and the cutter head is prevented from being replaced for machining operation;
2. the drilling head in the shape of the circular truncated cone is matched with the hole opening groove, holes can be formed efficiently, and the subsequent blade and the knife edge can rapidly expand the formed holes.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a schematic top view of the drilling head of the present invention;
fig. 3 is a schematic view of the three-dimensional structure of the drilling head of the present invention.
In the figure: 1. a cutter head; 2. a thread groove; 3. a blade; 4. installing a bolt; 5. a knife edge; 6. drilling a hole head; 7. and (5) opening a hole groove.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: a multi-edge thread milling cutter comprises a cutter head 1, thread grooves 2 and a mounting bolt 4, wherein the thread grooves 2 are formed in the cutter head 1, blades 3 are mounted below the cutter head 1, the blades 3 are distributed at equal angles below the cutter head 1, and the length of a cutter edge 5 on each blade 3 exceeds the edge position of the thread groove 2, so that the hole can be conveniently expanded and cut after drilling is completed, and meanwhile, scraps cut by the cutter edge 5 can be conveniently discharged from the thread groove 2;
be provided with mounting bolt 4 on blade 3, and blade 3 passes through mounting bolt 4 and tool bit 1 interconnect, and be provided with the edge of a knife 5 on the blade 3, drilling head 6 is installed to the lower extreme of tool bit 1, and seted up trompil groove 7 on the drilling head 6, be the integral structure between drilling head 6 and the tool bit 1, and drilling head 6 is round platform column structure, make things convenient for this milling cutter to carry out drilling processing through drilling head 6, trompil groove 7 is equal angular distribution on drilling head 6, and the right side edge of trompil groove 7 is sharp cutting structure, be favorable to carrying out cutting processing to the inner wall in hole when drilling head 6 drills.
The working principle is as follows: according to fig. 1, when the milling cutter is used for machining a metal workpiece, the drilling head 6 at the bottom of the cutter head 1 firstly contacts with the metal workpiece, according to fig. 3, the drilling head 6 in a circular truncated cone structure can drill on the metal workpiece, while the drilling head 6 drills, the hole opening groove 7 on the drilling head 6 can cut the edge of the hole, after the cutter blade 3 enters the hole, the knife edge 5 on the cutter blade 3 can further expand and cut the hole, and the scraps generated at the time can be discharged from the thread groove 2 on the cutter head 1, so that the multi-edge thread milling cutter is convenient for people to use.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
