Abstract
The utility model relates to a hardware processing tool, in particular to a bottoming drill, which comprises a cutter body, wherein the cutter body is provided with an inner mechanically clamped blade and an outer mechanically clamped blade, the inner mechanically clamped blade is arranged close to the center of the cutter body, and the outer mechanically clamped blade is arranged at the outer circle of the cutter body. The bottoming drill is characterized in that both two sides of the cutter body are provided with drill chip passages and a cooling passage is arranged in the cutter body. Besides, the drill chip passages are parallel to the axle center, and the inner mechanically clamped blade and the outer mechanically clamped are disposed on the center line. The utility model has the advantages that the bottoming drill with simple structure and fine using effect can cut in layering form and replace the blades, and is small in drilling resistance, smooth in chip discharge and fine in cutter body cooling effect and the like.
Description
Technical field:
The utility model relates to a kind of five metals machining tool, especially relates to a kind of indexable bottoming drill or clip type bottoming drill.
Background technology:
Now the specialty drill bit that is used for the higher steel plate drilling of rail drilling or hardness all exist easy to wear, and because drilling condition poor (rig poor rigidity, cooling abundant inadequately) thus influenced raising working (machining) efficiency and service life greatly.
Summary of the invention:
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and provide a kind of simple in structure, result of use good, applicable performance is strong and the removable bottoming drill of blade.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this bottoming drill, comprise cutter hub, clamped cutting bit sheet and outer clamped cutting bit sheet in cutter hub is provided with, interior clamped cutting bit sheet is arranged on by the cutter hub center, outer clamped cutting bit sheet is arranged on by cutter hub cylindrical place, it is characterized in that the cutter hub both sides are respectively arranged with the drilling cuttings passage, cutter hub inside is provided with the cooling duct.
Drilling cuttings passage described in the utility model and axis parallel.
The clamped cutting bit sheet is on the center line together with outer clamped cutting bit sheet in described in the utility model, and the geometry of two clamped cutting bit sheets, size are all consistent, and the working range of two clamped cutting bit sheets has overlapped part, and two blades cut simultaneously when drilling; Convertible another unworn blade or change clamped cutting bit sheet and continue cutting when each clamped cutting bit sheet damages if any blade need not wholely be scrapped cutter because of the blade damage causes, and falls end cost; After each clamped cutting bit sheet was contained on the cutter hub, anterior angle and relief angle that clamped cutting bit sheet itself is had reduced resistance during all to drilling and chip removal plays a role.
The utlity model has simple in structure, result of use good, applicable performance is strong and blade is replaceable and advantage such as cutter hub good cooling results.
Description of drawings:
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the left view of Fig. 1.
The specific embodiment:
Referring to Fig. 1, Fig. 2, the utility model embodiment bottoming drill comprises cutter hub 1, clamped cutting bit sheet 4 and outer clamped cutting bit sheet 5 in cutter hub 1 is provided with, two clamped cutting bit sheets are separately fixed at positions different apart from the axle center on cutter hub 1 end face, both interior clamped cutting bit sheet 4 is arranged on by cutter hub 1 center, outer clamped cutting bit sheet 5 is arranged on by cutter hub 1 cylindrical place, and the working range of two clamped cutting bit sheets has overlapped part, and cutter hub 1 both sides are provided with drilling cuttings passage 2.
The clamped cutting bit sheet of present embodiment can be provided with outer clamped cutting bit sheet 4 and interior clamped cutting bit sheet 5, and the boring of clamped cutting bit sheet the time be the annular cutting, and central core is cut simultaneously, though increased cutting resistance, does not also have when cutting problems such as the bad or shim bits of chip removal; Cutter hub 1 inside is provided with cooling duct 3 and is used for into water, can carry out fully in cooling, carry out cooling effect from the outside and will get well much than general.Interior clamped cutting bit sheet 4 is on the center line together with outer clamped cutting bit sheet 5, and more steady relatively when cutting, vibration reduces; The clamped cutting bit sheet adopts carbide alloy usually, and cutter hub 1 adopts structural steel or steel alloy usually.
The clamped cutting bit sheet of the utility model embodiment also can be designed to several different shapes to be more conducive to cutting, the design of drilling cuttings passage 2 generally is a straight trough shape, but also can be designed to spiral-shapedly, the fixed position of clamped cutting bit sheet also can be adjusted according to actual conditions.The simple deformation or the combination of every the utility model embodiment technical scheme and technical characterictic all should be thought to fall into protection domain of the present utility model.
Claims (3)
1, a kind of bottoming drill comprises cutter hub, clamped cutting bit sheet and outer clamped cutting bit sheet in cutter hub is provided with, interior clamped cutting bit sheet is arranged on by the cutter hub center, outer clamped cutting bit sheet is arranged on by cutter hub cylindrical place, it is characterized in that: the cutter hub both sides are respectively arranged with the drilling cuttings passage, and cutter hub inside is provided with the cooling duct.
