Description
Technical field
This practical property is related to a kind of handle of a knife, more particularly to a kind of handle of a knife of processing rotor seat.
Background technology
Rotator seat be located at crescent gear pump in a kind of parts, in crescent gear pump in there is important ground
Position, the in the prior art processing for rotator seat typically use cutter and repeatedly cutting are carried out to blank so as to process rotor
Seat, repeatedly cutting is so that processing efficiency greatly reduces.
Utility model content
The utility model lies in that providing a kind of cutter for processing rotor seat, solves repeatedly cutting so that processing effect
The problem of rate greatly reduces.
Technical solution described in the utility model is as follows：A kind of handle of a knife for processing rotor seat, it is characterised in that：The knife
Handle includes the installation end for installing blade and the fixing end for being fixed on lathe, is provided with the middle part of installation end
One section is circular cavity, and protrusion facing each other is provided with the end face of the cavity, is formed between adjacent two protrusion
Smooth arc-shaped groove, is provided with mounting portion for installing blade in the protrusion, the mounting portion be rectangular recess, is pacified
Set in dress portion positioned at the side of the side of cavity and raised end for open type, the protrusion is provided with use with being surveyed in mounting portion
The angle that the side of the side of cavity and raised end is formed in the arc groove for placing rectangular cutter corner, mounting portion is arranged to
Chamfering, the tapped through hole for fixed cutting tool is provided with the mounting portion, Cutting tool installation manner is when mounting portion, in adjacent two protrusion
Tool motion direction be located at different circumferencial directions.
The utility model is further arranged in the position of opposite raised upper mounting portion on chamber central axis pair
Claim to set.
The bottom that the utility model is further arranged to cavity is arranged to coniform.
The beneficial effects of the utility model：1 passes through the cutter energy in protrusion opposite two-by-two in processing rotor seat
The enough dual processing realized to the inner and outer of blank, rotator seat shaping is allowed in time processing, reduces and adds
The process of work, improves work efficiency and relatively simple for structure；2 cutters are detachable relative to mounting portion, after cutter is damaged,
Backing out bolt rotary cutter can continue to cut with the another side of cutter.

Groove；132- tapped through holes；133- chamferings.
Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not intended to limit the scope of the present invention.
The utility model, a kind of handle of a knife for processing rotor seat are described in detail with reference to Fig. 1 to Fig. 3, and handle of a knife includes
It is useful for the installation end 1 of installation cutter and the fixing end 2 for fixing handle of a knife, fixing end 2 is fixed on lathe, installation end 1
To be provided with a solution section be circular cavity 12 at middle part, cavity 12 is for secured blank and hair is controlled in working angles
The shape of base, is provided with facing each other raised 11 on the end face of cavity 12, smooth circular arc is formed between adjacent two protrusion 11
Shape groove, the side of protrusion 11 are provided with mounting portion 13 for installing blade, and mounting portion 13 is rectangular recess, in mounting portion 13
Set positioned at the side of the side of cavity 12 and raised 11 ends for open type, the inner side in mounting portion 13 positioned at mounting portion 13 is set
It is equipped with the arc groove 131 for placing rectangular cutter corner, the side shape of the side of cavity and raised 11 ends in mounting portion 13
Into angle on be arranged to chamfering 133, the tapped through hole 132 for fixed cutting tool is provided with mounting portion 13, in mounting portion 13
Rectangular cutter is installed, the arc groove 131 on mounting portion 13 allows the side of cutter primarily to make the easier for installation of cutter
Angle can place into, and the chamfering on mounting portion can be that another angle of cutter reserve the space of cutting, tapped through hole 132 with
Bolt coordinates for the firm of fixed cutting tool together, and bolt, rotary cutter knife can be back-outed after the one side of cutter is damaged
The opposite side of tool continues to cut, and in working angles, Cutting tool installation manner is when mounting portion 13, the cutter fortune in two adjacent protrusions 11
Dynamic direction in same circumferencial direction, can not realize the cutting to the interior outside of blank, in cutting, a pair of protrusion 11 relatively
On Tool in Cutting blank outside, the cutter in the opposite protrusion 11 of another pair is used for the inner side for cutting blank so that blank
The blank of rotator seat can be just formed after cutting at one time, it is not necessary to which repeatedly cutting, reduces manufacturing procedure, greatly improve
Work efficiency and simple in structure easy to operate.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and modification, above-mentioned vacation can also be made
If these improvements and modifications also should be regarded as the scope of protection of the utility model.
