Description
Technical field
The utility model belongs to cylinder body processing technique field, and in particular to cylinder bore inner spiral groove processing technology.
Background technique
Cylinder body 1 as shown in Figure 1 is equipped with cylinder bore inner spiral groove 11, cylinder bore inner spiral groove mechanical processing technique similar before this
It is to carry out spiral on numerically controlled lathe to insert milling, due to the characteristic of numerically controlled lathe, knife rest fixes a cutting tool central point and workpiece centre point very
Difficult centering, therefore spiral groove knife cutting edge only one sword, need to repeatedly be processed, low efficiency by workpiece hole inner spiral groove quantity
Under.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of for four shaft vertical machining center processing cylinder body
Hole inner spiral groove inserts milling cutter, improves processing efficiency.
In order to solve the above technical problems, the utility model adopts the following technical solution: one kind is in the processing of four shaft verticals
The heart processes cylinder bore inner spiral groove and inserts milling cutter, and the cutter hub including knife handle and connection knife handle head, the cutter hub circumferentially divides
Be furnished with cutting edge, the cutter hub offers chip space between adjacent two cutting edge, the center of the cutter be equipped with perforation cutter hub and
The maximum gauge in the interior cold hole of knife handle, the cutting edge is equal to cylinder bore inner spiral groove diameter, and the width of the cutting edge is equal to
The sword number of cylinder bore inner spiral groove width, the cutting edge is equal to cylinder bore inner spiral groove slot number, and the front end of the cutting edge is set
There is chamfering, the primary clearance of the cutting edge is 3-5 °, and the side relief angle of the cutting edge is on the basis of cylinder bore inner spiral groove angle
Upper 3-5 ° of increase.
Preferably, the head of the knife handle is equipped with cone tank, and the cutter hub is equipped with the tapered portion of insertion cone tank, the knife
Handle and cutter hub weld.
The utility model by adopting the above technical scheme, can disposably process helicla flutes more in cylinder bore, processing effect
Rate is high, improves the mechanical processing technique of such workpiece.
The specific technical solution and its advantages of the utility model will combine attached in the following detailed description
Figure is described in detail.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and detailed description:
Fig. 1 is cylinder bore inner spiral groove schematic diagram；
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is cutter hub end view.
Specific embodiment
Embodiment one, shown referring to figs. 2 and 3, one kind processing cylinder bore inner spiral groove for four shaft vertical machining center
Milling cutter is inserted, the cutter hub 22 including knife handle 21 and connection knife handle head, the cutter hub is circumferentially distributed cutting edge 221, institute
It states cutter hub and offers chip space 222 between adjacent two cutting edge, the center of the cutter is equipped with the interior cold of perforation cutter hub and knife handle
Hole 23, the front end of the cutting edge 221 are equipped with chamfering, and the primary clearance of the cutting edge 221 is 3-5 °, the cutting edge 221
Side relief angle increases 3-5 ° on the basis of cylinder bore 11 angle of inner spiral groove.
Wherein, the Leading end chamfer of cutting edge 221 be do cutter incision aperture when guidance oblique angle, 221 primary clearance of cutting edge,
It is general to use 3-5 °, it prevents cutting edge flank from wiping with spiral groove bottom and touches, cause helicla flute bottom roughness overproof；Cutting edge
The 221 two sides side Xu You relief angles, side relief angles are depending on cylinder bore inner spiral groove angle, generally on the basis of spiral angle
Increase 3-5 °, prevents cutting edge two sides from wiping with cylinder bore inner spiral groove two sides and touch, cause helicla flute roughness overproof even
Deformation；Chip space 222 is conducive to chip removal and cutting fluid discharge in cylinder bore；Interior cold hole 23 is conducive to cutting heat dissipation and chip removal.Cutting edge
221 maximum gauge is equal to cylinder bore inner spiral groove diameter, and the width of cutting edge 221 is equal to cylinder bore inner spiral groove width, cuts
The sword number for cutting sword is equal to cylinder bore inner spiral groove slot number, and cutter hub length is depending on cylinder bore inner spiral groove effective length.
The head of the knife handle is equipped with cone tank, and the cutter hub is equipped with the tapered portion of insertion cone tank, the knife handle and knife
Body welding.Welded type is used under the premise of guaranteeing tool precision and intensity, reduces the cost of charp tool.
Debugging processing method: cylinder bore is machined to helicla flute bottom outlet completion status, cylinder bore aperture is upward, center cutter
It is consistent with cylinder bore center, processed by the program of screw tap tapping, cutting parameter according to the helical angle of helicla flute, stroke come
It determines.
The slotting milling cutter of the utility model can disposably process helicla flutes more in cylinder bore, high in machining efficiency, mention
The mechanical processing technique of such high workpiece.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, being familiar with the those skilled in the art should be understood that the utility model includes but is not limited to retouch in specific embodiment above
The content stated.The modification of any function and structure principle without departing from the utility model is intended to be included in the range of claims
In.
