Description
Technical field
The invention belongs to machining equipment technical field, particularly relate to a kind of high-pressure gear pump pump cover rose reamer.
Background technology
As in figure 2 it is shown, high-pressure gear pump pump cover workpiece includes pump cover body 5, the inwall of pump cover body 5 is machined with appearance
Putting the axis hole of bearing oil jacket and gear shaft, the inwall 4 of axis hole is straight, and the end face of pump cover body 5 is straight, and both of which has height
Planeness value and low roughness value.R0.4 is processed in the end face of pump cover body 5 and the i.e. aperture, inwall 4 joint of axis hole
Chamfering, effect be in axis hole install bearing oil jacket when play guide effect and protective effect, it is simple to oil jacket assembling
Avoid sharp-pointed aperture that oil jacket is caused damage simultaneously.In actual processing, above-mentioned chamfer site is carried out by general employing rose reamer
Processing, workpiece is fixed on the operating desk of machining center, and the cutter head of rose reamer rotates one week along the trend of chamfer site and completes down
The processing at angle.The rose reamer carrying out above-mentioned chamfer machining in prior art generally comprises the connecting rod of cylinder, in connecting rod
Front end is provided with the cutter head of cylinder, and the transition in connecting rod and cutter head is processed into the arcuate shape of R0.4.Above-mentioned
There are the following problems in reality is processed for the rose reamer of structure: being limited to processing and positioning precision, above-mentioned rose reamer is in axis hole aperture
When place makees annular cutting movement, the sidepiece of its cutter head can produce certain shear action to the inwall of axis hole, causes axis hole size
With the destruction of inwall fineness, the top of cutter head can produce certain shear action to the end face of pump cover workpiece, causes end face to put down
Face degree and the destruction of fineness.
Summary of the invention
The present invention solves technical problem present in known technology and to provide one to be prevented effectively from during chamfer machining right
The high-pressure gear pump pump cover rose reamer that the end face of pump cover workpiece and shaft hole inner wall damage, it is ensured that the size of workpiece is not destroyed
And end face and the flatness of inwall and fineness.
The present invention solves that technical problem is adopted the technical scheme that present in known technology: a kind of high-pressure gear pump pump cover
Rose reamer includes the connecting rod of cylinder, is provided with integrated, the cutter head of taper platform shape, the conical surface of cutter head in its front end
And the angle between connecting rod center line is 5 °, the end of connecting rod, cutter head outer rim the most tapered, the conical surface and company at this
Angle between extension bar center line is 95 °；Between the conical surface and the conical surface of cutter head of connecting rod end, it is provided with radius be equal to
The circular arc transition portion of 0.4mm.
Advantages of the present invention and good effect be: the invention provides a kind of reasonable in design for high-pressure gear pump pump cover
The rose reamer of chamfering, compared with the rose reamer of existing straight-bar shape, by the outer wall of cutter head and connecting rod adjacent therewith
End face on the conical surface is set so that this rose reamer is when carrying out chamfer machining to the axis hole aperture of pump cover workpiece, except radius is
Outside the circular arc transition portion of 0.4mm contacts with aperture, the end of connecting rod is sufficiently far from the end face of pump cover body, cutter head
Outer wall be sufficiently far from the inwall of axis hole, so during chamfer machining the flatness of pump cover body end face and fineness and
The size of axis hole, flatness and fineness are not damaged, and improve the product quality of pump cover workpiece.
Accompanying drawing explanation
Fig. 1 is that the master of the present invention regards and broken section structural representation；
Fig. 2 is the front sectional view that the present invention uses state.
In figure: 1, connecting rod；2, transition portion；3, cutter head；4, inwall；5, pump cover body.
Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example and describe in detail as follows:
Referring to Fig. 1, the present invention includes the connecting rod 1 of cylinder, is provided with integrated, taper platform shape in its front end
Cutter head 3, the angle between the conical surface and connecting rod 1 center line of cutter head 3 is 5 °, the end of connecting rod 1, cutter head 3
Outer rim the most tapered, at this, the angle between the conical surface and connecting rod 1 center line is 95 °.
The radius circular arc transition portion 2 equal to 0.4mm it is provided with between the conical surface and the conical surface of cutter head 3 of connecting rod 1 end.
Using method: be arranged on the tool rest of machining center by this rose reamer, sets mobile route.Pump cover workpiece is fixed on
On the operating desk of machining center.Starting tool rest, rose reamer moves high-speed rotation simultaneously along preset path.The transition part of circular arc
Dividing 2 directly to contact with the aperture of axis hole, the end of connecting rod 1 is sufficiently far from the end face of pump cover body 5, the outer wall of cutter head 3
It is sufficiently far from the inwall of axis hole, the above-mentioned position that may contact is not produced infringement.
Claims (1)
