Abstract
The utility model provides a milling inner barrier surface turnable cutter disc. A plurality of guide grooves are uniformly arranged on the excircles of a left cutter disc and a right cutter disc, the stress surface of each guide groove is provided with a cutter blade, the guide grooves are internally provided with wedge-shaped pressure blocks, and the inclined surfaces of the wedge-shaped pressure blocks are in contact with the cutter blades and are fixed in the guide grooves through screws; an adjusting screw is arranged at the rear part of the stress surface of each cutter blade; the installation surfaces of the left cutter disc and the right cutter disc are provided with inner countersinks, and the inner countersinks are internally provided with wedge-shaped threaded adjustment blocks correspondingly. According to the utility model, the total thickness of the milling inner barrier surface turnable cutter disc can be controlled within the barrier opened range of a part, the cutter blades can be fixed in the guide grooves under the action of the wedge-shaped pressure blocks, and the movable installation of the cutter blades not only achieves the convenience for use, but also saves the welding cost and ensures that the cutter disc does not deform due to welding, so that the stability and reliability in use are ensured. The milling inner barrier surface turnable cutter disc provided by the utility model well solves the problems of processing of a workpiece with inner barrier surface size ranging from 40 mm to 45 mm, and is convenient to operate and practical in structure.
Description
Technical field
The utility model relates to milling cutter tools.The indexable cutterhead of a kind of milling internal retaining surface particularly.
Background technology
The internal retaining surface size little (40mm-45mm) of auto parts and components, high (the tolerance: ± 0.1 ~ 0.2mm) of precision, processing this type of opens block face and need in omnipotent milling, carry out, and cutter diameter can not be less than 200mm, and on market, indexable cutterhead thickness minimum more than diameter 200mm is 25mm, two to coil thickness be together 50mm, surpass 45 mm, owing to there is no suitable cutterhead, to process while opening block face in this series products and waste time and energy, quality is also difficult to guarantee.
At present generally adopt nonstandard welding cutterhead, blade is directly welded on cutterhead, when blade is blunt nosed or destroy after just need to again weld, reweld after blade at every turn, cutterhead is distortion just, causes out block face machined surface roughness overproof, has a strong impact on subsequent handling quality.
And its structure of indexable cutterhead is in the market: open the indexable cutterhead of block face in milling, comprise left and right two cutterheads, left and right two cutterheads are installed together, on the cylindrical of left and right two cutterheads, be evenly provided with a plurality of gathering sills, on the stress surface of each gathering sill, be provided with blade, in gathering sill, be provided with wedge shape briquetting, the inclined-plane of wedge shape briquetting contacts with blade, and is fixed by screws in gathering sill; After each blade stress surface, be provided with one and adjust screw.But the thickness of two cutterheads is certain value, while combining, its width is far longer than internal retaining surface size (40mm-45mm), thus just cannot directly use, or the thickness of two cutterheads of attenuate, because the reason of error, cannot realize the technique of time processing moulding.
Summary of the invention
The utility model, in order to reduce the cost of processing internal retaining surface, improves production capacity, guarantees machining accuracy, the special indexable cutterhead of a kind of milling internal retaining surface that proposes.
For this reason, the technical solution of the utility model is: the indexable cutterhead of milling internal retaining surface, comprise that left and right two cutterheads are installed together, on the cylindrical of left and right two cutterheads, be evenly provided with a plurality of gathering sills, on the stress surface of each gathering sill, be provided with blade, in gathering sill, be provided with wedge shape briquetting, the inclined-plane of wedge shape briquetting contacts with blade, and is fixed by screws in gathering sill; After each blade stress surface, be provided with one and adjust screw, it is characterized in that: the installed surface of left and right two cutterheads is provided with interior counterbore, in interior counterbore, correspondence is provided with adjustment block.
Improvement to such scheme is: the thickness of described left and right two cutterheads is 17 ± 1mm, and the interior counterbore degree of depth is 5 ± 1mm.
Improvement to such scheme is: described adjustment block is nut and screw adjustment block.
Beneficial effect:
The utility model is because left and right two cutterheads are installed together, making its gross thickness can be controlled at parts opens in the scope of gear, precision can be controlled, blade can be fixed in gathering sill by the effect of wedge shape briquetting, the activity of blade is installed and is not only convenient to use, and saved welding cost, and can not also cutterhead distortion because of welding, guaranteed that it uses to obtain stability and reliability.
The adjustment screw being provided with below at each blade stress surface is that blade is finely tuned and arranged.
The installed surface of left and right two cutterheads is provided with interior counterbore, and it is in order to regulate out the gear distance of gear, to use convenient that the interior correspondence of interior counterbore is provided with adjustment block.
The thickness of described left and right two cutterheads is 17 ± 1mm, and the interior counterbore degree of depth is that 5 ± 1mm makes the adjusting range of two cutterheads expand as 10mm, has increased adjusting range the scope of its application is also strengthened.
The use of nut and screw adjustment block can be finely tuned the relative rotation of cutterhead, makes it more accurate.
In the indexable cutterhead of the utility model has well solved, open the workpiece processing of block face size within the scope of 40mm-45mm, product percent of pass has reached more than 99.8%, improves production capacity more than 80%, and easy to operate, structure is practical.
