Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Embodiment
As Figure 1-3, a kind of fraising frock is disclosed in the present embodiment, for fixing carbon commutator 1, and coordinates reamer
Reamed on carbon commutator 1, including base 2, the frock body 4 being arranged on base 2 and the work being rotatably connected on base 2
Part baffle plate 6,
Above-mentioned frock body 4 is provided with the location hole 8 for being matched with the shape of carbon commutator 1, and carbon commutator 1 to be reamed is set
In above-mentioned location hole 8, and the center of carbon commutator to be reamed 1 is coaxially disposed with the hole heart of location hole 8, above-mentioned location hole 8 pairs
Carbon commutator 1 to be reamed carries out the positioning of circumferencial direction；As shown in Figure 1, 2, the center of location hole 8 is circular hole 81, along circular hole
It is provided with one week multiple slot holes 82, when carbon commutator 1 is placed in location hole 8, its copper shell is limited in circular hole 81, its carbon plate
(namely commutator segment) is limited in each slot hole 82 correspondingly, and thus location hole 8 carries out circumference side to carbon commutator 1
To positioning, it is ensured that carbon commutator 1 will not be rotated during fraising；
Specifically, this has a support bar 20 on the base 2, above-mentioned workpiece baffle 6 is rotatably connected on support bar 20, on
Workpiece baffle 6 is stated for the movement limited on the axial direction of carbon commutator to be reamed 1, which is provided with what is passed through from top to bottom for reamer 3
Through hole 10, workpiece baffle 6 compresses carbon commutator to be reamed 1 when workpiece baffle 6 turns to the surface of location hole 8, and above-mentioned
The hole heart of both through hole 10 and location hole 8 is coaxially disposed.During handling carbon commutator 1, workpiece baffle 6 is laterally rotated, with side
Just carbon commutator 1 is loaded in location hole 8, or the carbon commutator 1 of end of having reamed is taken out from location hole 8；Fraising
When, to positioned at the surface of location hole 8, now workpiece baffle 6 compresses carbon commutator 1 to turning of work piece baffle plate 6, forms carbon commutator
1 in the vertical direction it is spacing, thus, carbon commutator 1 is positioned by you simultaneously in circumferencial direction and vertical direction, is not had any
Shift flexibly and elastic deformation, reamer 3 is stretched on frock body from through hole 10, and reaming operations are carried out to commutator.This reality
With the traditional clipping fixed form of new change be circumferencial direction, axially while spacing fixation, can realize carbon commutator
Precise positioning reams, it is ensured that the circularity and dimensional accuracy of product fraising.
As further improvement of the utility model, pushing tow hole 12, above-mentioned pushing tow hole 12 and positioning are provided with above-mentioned base 2
Both the hole hearts of hole 8 are coaxially disposed, and pushing tow first 14 is provided with above-mentioned pushing tow hole 12, and one pushing tow of above-mentioned first 14 connection of pushing tow lifts up bar
16, the middle part that above-mentioned pushing tow lifts up bar 16 is arranged on one and lifts up on activity supporting point 18, and its other end extends out to the outside of base 2,
Lift up pushing tow and lift up the carbon commutator 1 after the fraising of the upward pushing tow of above-mentioned pushing tow first 14 terminates after bar 16.In this way, can terminate fraising
Carbon commutator 1 afterwards can be quickly removed, and improve fraising efficiency.
Used as further improvement of the utility model, the bottom of above-mentioned location hole 8 is provided with a platform, the table top of above-mentioned platform
End face with fraising carbon commutator 1 is fitted setting, so ensures the perpendicularity of hole machined in carbon commutator 1.
After the carbon commutator 1 of fraising is arranged in location hole 8, between the internal diameter of location hole 8 and the fraising external diameter of carbon commutator 1
Gap is 0.03-0.06mm, in this way, from alignment, can will not produce the situation of skew in fraising.
In order to further improve the dimensional accuracy of fraising, as shown in figure 4, can also enter by center frock 24 before processing
Row positioning, to ensure the not deviation of center during fraising, specifically, to opening up through hole in center frock 24, to center work
24 are filled to be placed on frock body 4, and through-hole alignment location hole 8 is placed, feeler gauge 22 is inserted in through hole through hole from top to bottom, if
Feeler gauge 22 can be sequentially inserted into location hole 8, through hole 10, illustrated to center success；Otherwise to center failure, it is necessary to adjust again
The position of whole frock body 4.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.Various modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can in other embodiments be realized in the case where spirit or scope of the present utility model are not departed from.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
