Description
Technical field
The utility model relates to process tool technical field, is specifically related to a kind of rough turn process tool.
Background technology
Existing cutter is when adopting clamping seat clamping, and owing to just adopting clamping seat to clamp handle of a knife, and handle of a knife itself does not hold out against the structure of clamping seat, causes the clamping of cutter insecure, easily occurs the phenomenon that cutter loosens.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of structure simple, reasonable in design, can clamping firmly rough turn process tool.
The technical scheme realizing goal of the invention of the present utility model is as follows:
Rough turn process tool, comprise cylindrical knife shank, be arranged on the processing blade of handle of a knife one end, described processing blade comprises the side face sword being positioned at handle of a knife taper processing department foremost He being positioned at handle of a knife end outer peripheral face, is less than the cylinder connection of handle of a knife between described taper processing sword and side face sword by diameter; The clamping end of described handle of a knife offers axial pilot hole along handle of a knife axis direction, with offer the radial direction through hole be communicated with axial pilot hole along shank diameter direction, in radial direction through hole, be provided with jacking block, be provided with in axial pilot hole and jacking block is ejected radial direction through hole make jacking block protrude from the impeller of handle of a knife outer peripheral face.
Have employed such scheme, handle of a knife is clamped on clamping seat, the clamping to handle of a knife is formed by clamping seat, and promote jacking block by impeller afterwards, and jacking block can be pushed part outwards ejects, even if jacking block part protrudes from handle of a knife outer peripheral face, the jacking block top of such projection realizes the effect held out against to the clamping face of clamping seat, increases the assembling fastness of handle of a knife with this; Such structure ensures in process, and cutter can not produce movement, thus also can ensure the security of precision and the processing of processing.
Further, described radial direction through hole be at least provided with two and the centerline of two radial holes on the same sagittal plane of handle of a knife, above-mentioned jacking block is provided with one to one in each radial hole, described jacking block is provided with inclined-plane, impeller is provided with the driving inclined-plane coordinated with jacking block inclined-plane, and the afterbody outer wall of described impeller adopts engagement thread to coordinate with the inwall of axial pilot hole.When impeller inwardly promotes, by the driving inclined-plane of its end and the cooperation of jacking block ramp, jacking block can by top in protruding handle of a knife appearance planar, and impeller threadedly can lock onto formed in axial pilot hole spacing.
Further, in order to make the jacking block protruding from handle of a knife outer peripheral face automatically reset, be provided with between two jacking blocks for pullling the elastic component of two jacking blocks to both central motions.
Further, described taper processing department comprises two the end face swords be arranged on tapered end, become end face chip area lower than end face tooth shape between both ends of the surface sword, described side face sword is four helical edges being arranged on handle of a knife outer peripheral face, forms side face chip area between adjoining spiral sword.
Further, form included angle A between described both ends of the surface sword, included angle A is 110 °-120 °.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the C-C sectional view of Fig. 1;
Fig. 3 is the D-D sectional view of Fig. 1;
Detailed description of the invention
See Fig. 1,2,3, rough turn process tool, comprise cylindrical knife shank 1, be arranged on the processing blade of handle of a knife one end, processing blade comprises the side face sword 3 being positioned at handle of a knife taper processing department foremost 2 and being positioned at handle of a knife end outer peripheral face, and taper processing department comprises two the end face swords 4 be arranged on tapered end, becomes end face chip area 5 between both ends of the surface sword lower than end face tooth shape, form included angle A between both ends of the surface sword, included angle A is 110 ° or 115 ° or 120 °; Side face sword is four helical edges 6 being arranged on handle of a knife outer peripheral face, forms side face chip area 7 between adjoining spiral sword.
The cylinder 8 being less than handle of a knife by diameter between taper processing sword and side face sword connects; Cylinder adopts oblique sword 19 to be connected with between side face sword, taper processing department junction, oblique sword and handle of a knife axis direction form included angle B, and included angle B is 25 ° to 35 °, can process workpiece smoothly like this, also can make way in process, the discharge of chip and interrupt chip; The clamping end of handle of a knife offers axial pilot hole 9 along handle of a knife axis direction, with offer the radial direction through hole 10 be communicated with axial pilot hole along shank diameter direction, jacking block 11 is provided with in radial direction through hole, be provided with in axial pilot hole and jacking block is ejected radial direction through hole make jacking block protrude from the impeller 12 of handle of a knife outer peripheral face, this impeller is cylindrical;
Radial direction through hole be at least provided with two and the centerline of two radial holes on the same sagittal plane of handle of a knife, above-mentioned jacking block is provided with one to one in each radial hole, jacking block is provided with inclined-plane 13, impeller is provided with the driving inclined-plane 14 coordinated with jacking block inclined-plane, this driving inclined-plane is formed on the tapering point of impeller end, and the afterbody outer wall of impeller adopts engagement thread to coordinate with the inwall of axial pilot hole.Be provided with for pullling the elastic component 15 of two jacking blocks to both central motions between two jacking blocks, elastic component can be other elastic components such as extension spring, as long as can realize pulling two jacking blocks to both central motions.
In concrete enforcement, jacking block is fixedly installed limited block 16, limited block, with by screw 17, the latch segment 18 be locked on handle of a knife coordinates, skids off completely when avoiding jacking block to stretch out like this from radial direction through hole; Sketch and of the present utility model hold out against principle: when impeller advances, can by jacking block jack-up, namely the surface that the outer surface of jacking block can protrude from handle of a knife withstands on effect clamping seat realizing hold out against, and when cutter is taken off, backhaul dynamic outside impeller, elastic component between jacking block is for pulling the reset of jacking block, and namely jacking block is retracted in handle of a knife, the outer surface of jacking block lower than or the outer surface of fair handle of a knife.
