Abstract
The utility model discloses a novel modular type heavy-duty turning tool, which is used for the external cylindrical turning on the horizontal and the vertical lathes of the heavy-duty machine, the metallurgy machine, the mining machine and the power station equipment. The tool head and the tool bar of the turning tool are connected in an assembling mode, and a tool blade adopts an upward pressure type assembly structure. The tool blade is provided with a mechanism which can make the tool blade positioned in a stepping mode after being reground and has the thermal insulation and thermolysis measure which prevents the thermal distortion of a connecting piece. Each assembling part adopts the wedge shape positioning clamping means with a low machining precision which is firm and reliable. The utility model has the advantages of high productive efficiency, convenient operation, high durability and utilization ratio and good preservation of the precision, being advanced, and saving a large amounts of tool bar materials.
Description
The utility model relates to a kind of assembly type heavy-duty turning tool, belongs to outer garden lathe tool class.Be applicable to and do the turning of outer garden on the horizontal and vertical lathe such as heavy type, metallurgy, mining machinery, power station equipment.
At present, the heavy-duty turning tool of China's employing mainly contains: (1) brazing carbide lathe tool (see figure 1).It is that carbide chip is welded on the knife bar groove.(2) carbide alloy clip type lathe tool, it is that carbide chip is clamped in (hereinafter to be referred as " clip type ") on the knife bar with the method for mechanical clamping for a (see figure 2)." clip type " lathe tool is without welding, avoided having improved tool life because of the welding defectives such as descending, crack that causes blade hardness, and tool change time short (only tool changing sheet), improved production efficiency.But carbide alloy clip type lathe tool is used for the big heavy turning of cutting output, also has big weakness, causes its generally use to be restricted.Its shortcoming is as follows: (1) knife bar and cutter head are monoblock types, and one can only be made into a kind of tool cutting edge angle cutter head to lathe tool, and the processing work tool cutting edge angle changes must corresponding replacing whole lathe tool, and heavy-duty turning tool is very heavy, cause this bring use inconvenient.(2) " clip type " lathe tool that adopts at present, the connector of its fixed blade (housing screw and lever etc.) directly engages with cutter head, when cutting data is big, connector is subject to high temperature deformation and produces loading and unloading blade difficulty, even because of thermal deformation causes clamping not strongly, blade is loosening, can't use.(3) present " clip type " lathe tool, blade can not be refaced.
Task of the present utility model is to solve the heaviness that the bigger heavy-duty turning tool of cutting data adopts brazing carbide lathe tool and carbide alloy clip type lathe tool, use inconvenience, thermal deformation causes that blade clamps not strongly and problem such as blade throw away, designs a kind of novel assembly type heavy-duty turning tool to solve the drawback of above-mentioned lathe tool.
Task of the present utility model realizes with following mode: a triangular pyramid to right lateral side is set, to make the usefulness of location between the two between (1) cutter head and the knife bar.Its clamping is to assemble by the bindiny mechanism that is provided with the inclined-plane briquetting to be one.(2) cutter head adopts and to have heat insulation and can make the last pressure type structure of blade stepping.Be that cutter head tightens up bridge shape pressing plate, locating piece, tool tip from top to bottom with housing screw.Blade, edge bearing are placed on front end, compress under bridge shape pressing plate, and its contact-making surface is the inclined-plane.The curved washer nut screwing clamping that housing screw is provided with the tool tip bottom surface, and directly do not combine with tool tip etc.Tool tip is provided with groove and long first slotted eye, and the angle wedging that matches by setting on the right side, back between locating piece and the tool tip, and pushes down through the rear end of bridge shape pressing plate, so that forms inclined-plane groove wedge shape stepping mechanism, makes blade realize stepping.(3) primary clearance of the lathe tool various tool cutting edge angle cutter heads of joining, pay geometric parameters such as relief angle, cutting edge inclination and realize by the processing knife bar.(4) on the knife bar table top by before the blade and after respectively offer the heat radiation through hole, and trench digging is communicated with.
This assembly type heavy-duty turning tool, its techno-economic effect is as follows: (1) is compared with whole " clip type ", knife bar of this lathe tool can be by processing request, load onto the cutter head of various different tool cutting edge angles, replace manyly, can save a large amount of knife bar materials like this clamped cutting bit (promptly a cutter head is equivalent to a clamped cutting bit).(2) wedge shape location clamping mode is adopted in this lathe tool many places, has not only guaranteed the reliability of the big and thump of heavy turning strength, and also need not to carry out high accuracy process on making.(3) on precision keeps, the wearing and tearing of each contact-making surface enlarge contact area, increase bond strength, help using.(4) blade can be refaced, and improves the carbide chip utilization rate.And because of Sharpening a knife blade and regrinding do not have parameter request how much, the sharpening action is simple, can save time more than five times.(5) adopt groove stepping running fix behind the blade regrinding, control easy.(6) syndeton is simple, and is flexible to operation, and tool changing only need be changed little small bit tool, need not often to load and unload knife bar, reduces loading and unloading labour intensity.(7) there is the heat insulation and dissipation measure in the cutter head zone, connector screw thread thermal deformation in the time of can preventing heavy cutting.
