Description

A kind of drilling tool
Technical field
The utility model relates to Machining Technology field, can process specifically hole, conventional aperture, can process again a kind of drilling tool in hole, large aperture.
Background technology
Drilling tool is a kind of rotation and head end has the instrument of cutting power, generally with carbon steel SK, or the material such as high-speed steel SKH2, SKH3 through milling system or rolling again through quenching, grind after tempering heat treatment and form, for the Drilling operation on metal or other material, its scope of application is extremely wide, can apply to use on the toolroom machines such as lathe, lathe, milling machine, electric hand drill, all have corresponding standard for dissimilar drill bit.
In metallurgical industry enterprise production process, the parts of equipment component are provided with hole, large aperture, breaking down while needing emergency maintenance, usually fail to be equipped with the drilling tool in hole, large aperture due to production scene, need to deliver to relevant production unit and process, entrust that the process required time of cooperation processing is long, expense is high, affects the normal production of enterprise simultaneously, cause production cost, maintenance cost to raise, have influence on the economic benefit of enterprise.
Utility model content
The purpose of this utility model is to provide a kind of hole that can either processing criterion specification aperture, can process safely, efficiently again the drilling tool in hole, large aperture, meets the job requirements in production process, the problem that cannot process hole, large aperture to solve common specification drilling tool.
For addressing the above problem, the technical scheme that the utility model is taked is:
A kind of drilling tool, it comprises drillstock, drilling rod, drill bit, drillstock bottom is connected with drilling rod, drilling rod bottom is connected with drill bit, and drillstock is conical, and drilling rod is cylindrical, described drilling rod is provided with at least one group of knife bar hole, positioning screw hole, and the bottom outer rim of described drilling rod is provided with positioning sleeve.
As further improvement of the utility model, the center line of described knife bar hole and described positioning screw hole is mutually vertical and in same plane.
Further improve as of the present utility model, the internal diameter of described positioning sleeve is consistent with the external diameter of described drill bit, and the external diameter of described positioning sleeve is consistent with platen centre bore internal diameter.
The utility model is provided with drill bit in the bottom of drilling rod, and described drill bit is lathe unit-type drill head, meets the requirement in processing hole, conventional aperture; At least one group of knife bar hole is set on drilling rod, the cutter of all size can be installed in knife bar hole, and corresponding positioning screw hole is set, by set screw fixed cutting tool is installed, be used for processing wide-aperture hole; The size and dimension in knife bar hole can arrange according to the size and shape of the knife bar of cutter that production scene is equipped with; Positioning sleeve in the outer rim setting of the bottom of drilling rod can be fixedly installed to the utility model in the centre bore of platen, and the center of location drilling tool and platen makes that the utility model axiality is good, security performance is high.The utility model is simple in structure, easy to install, of many uses, can meet the requirement to workpiece processing hole, plurality of specifications aperture in mechanical processing process, uses existing standard production instrument, reaches and enhances productivity, the effect reducing production costs.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of structural representation of the present utility model in Fig. 1;
In figure: 1, drillstock, 2, drilling rod, 3, drill bit, 4, knife bar hole, 5, positioning screw hole, 6, positioning sleeve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, a kind of drilling tool shown in Fig. 2, a kind of drilling tool, it comprises drillstock 1, drilling rod 2, drill bit 3, drillstock 1 bottom is connected with drilling rod 2, drilling rod 2 bottoms are connected with drill bit 3, drillstock 1 is conical, drilling rod 2 is cylindrical, drilling rod 2 is provided with two groups of knife bar holes 4, positioning screw hole 5, the center line of knife bar hole 4 and positioning screw hole 5 is mutually vertical and in same plane, the bottom outer rim of drilling rod 3 is provided with positioning sleeve 6, the internal diameter of positioning sleeve 6 is consistent with the external diameter of drill bit 3, the external diameter of positioning sleeve 6 is consistent with platen centre bore internal diameter, between positioning sleeve 6 and drill bit 3, it is matched in clearance.
The specification of drillstock 1 is consistent with standard drillstock with lathe, and the specification of drill bit 3 is consistent by the specification of unit-type drill head with lathe.
Drilling rod 2 is provided with two groups of knife bar holes 4, positioning screw hole 5 in the present embodiment, in actual production, 1 ~ 3 group of knife bar hole can be set as required, and the distance between adjacent knife bar hole is determined according to the length of drilling rod and rigidity; In the present embodiment knife bar hole be shaped as rectangle, in actual production, the shape and size in knife bar hole can arrange according to the shape and size of installed cutter and cutter bar.
Concrete use procedure of the present utility model is: suitable cutter and cutter bar is assigned in feed rod hole 4, in positioning screw hole 5, set screw is installed, screw set screw, fix cutter; Positioning sleeve 6 is installed to the centre bore of lathe workbench, adjusts cutter; To be processed is fixed on lathe workbench, starts lathe, make drill bit first on workpiece, carry out the processing in basic hole, then adjust in proper order the bite of cutter and process to machined part, obtain the hole requiring.
The utility model is simple in structure, processing parts in time, quick, and axiality and security performance good.
