Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only to explain
This utility model, is not used to limit this utility model.Additionally, institute in this utility model disclosed below each embodiment
As long as the technical characteristic being related to does not constitute each other conflict and just can be mutually combined.
Fig. 1 is under cutting shape for being shown as the inboard aperture port chamfering device of this utility model preferred embodiment
Overall structure diagram, Fig. 2 is overall structure diagram of the inboard aperture port chamfering device under non-cutting state.Such as Fig. 1
With shown in Fig. 2, the inboard aperture port chamfering device mainly includes the function groups such as fixed base of skate-board 1, slide plate 8, push-pull bar 10 and knife bar 7
Part, will one by one carry out specific explanations explanation to it below.
Fixed base of skate-board 1 for being threadedly coupled with drilling machine lathe bed, and for example passes through swallow as the installation foundation of other assemblies
Stern notch and guide post 5 install slide plate 8 to couple.More specifically, the fixed base of skate-board can thereon, lower surface is respectively provided with
Have and for example adopt the overhead gage 2 and lower baffle plate 3 being screwed, for limiting maximum shift motion of the slide plate 8 in vertical direction, together
When prevent it from deviating from；Additionally, fit is gone back on guide post 5 is provided with compression spring 4, and the compression spring is arranged on slide plate
Between 8 lower surface and lower baffle plate 3, the other assemblies by slide plate and carrying thereon in non-cutting state can be caused in this way
Keep being in suitable initial position.
For slide plate 8, it is designed to along horizontal direction to stretch out and be capable of achieving vertical direction to move up and down；More
Body ground, the slide plate has circular mold cavity, and the overall outer ring with a deep groove ball bearing 9 of this circular mold cavity performs interference and matches somebody with somebody
Close, bottom and the bearing face of deep groove ball bearing 9 of this circular mold cavity fit；Further, it is also possible in circular mold cavity oral area dress
There is flat head screw, prevent bearing from deviating from.
For push-pull bar 10, it is collectively constituted by circular ring structure and rod-like structure, wherein the outer ring of the circular ring structure and depth
The inner ring of ditch ball bearing 9 performs interference fit, thus installs with deep groove ball bearing 9 and the slide plate 8 and couples integral, even if also
Obtaining push-pull bar 10 can together move therewith with moving up and down for slide plate 8；Additionally, the rod-like structure is along vertical direction to downward
Stretch and perform gap with knife bar 7 and install, and then drive this knife bar in the vertical direction to perform and slide up and down.
For knife bar 7, it is equally arranged along vertical direction, and its upper end is by drill chuck 6 and drilling machine
Main shaft is connected, and its lower end is provided with blade 12 by bearing pin 11；The blade is upper and lower with the knife bar in the vertical direction
The corresponding rotation performed around the bearing pin of slip, thus realizes switching between cutting state and non-cutting state.More specifically
Ground, the main body of push-pull bar 10 can be designed as being placed in the axial notch of knife bar 7, lower end may be designed as arcwall face so as to knife
The afterbody arcwall face of piece 12 fits, and in this way when push-pull bar 10 is slided up and down, band cutting blade 12 rotates, and makes blade 12 exist
Cutting state flexibly switches with non-cutting state.
Specific explanations are given below according to the course of work of inboard aperture port chamfering device of the present utility model.
First, by selecting the suitable installation site of fixed base of skate-board 1 and adjustment drill press spindle initial bit in drilling machine lathe bed
Put, make whole inboard aperture port chamfering device be in cutting state；Starting lathe rotates main shaft, and by drill chuck 6 knife bar 7 is driven
Rotation.
Then, slide plate 8 is pushed down on to extreme position, push-pull bar 10 is rotated up with cutting blade 12, make blade 12 complete
Inside knife bar 7, then, operation drill press spindle is moved down, and makes knife bar 7 pass through the hole for needing inner side chamfering to suitable depth
Degree, removes the power that pushes down on of slide plate 8, and slide plate 8 is moved upward to initial position under the spring-force driven dual of spring 4, while band
Dynamic push-pull bar 10 is moved up, and then blade 12 is rotated to cutting state；In this case, it is possible to operate drill press spindle upwards
It is mobile, you can chamfering is carried out to inboard aperture mouth.
Finally, after the completion of chamfering, operation drill press spindle moves down suitable distance, pushes down on slide plate 8 to extreme position,
Drill press spindle is operated to exit hole in piece part by moving up again；Repeat operations described above, you can to other inboard aperture causes for gossip
Existing chamfering.
To sum up, can be carried out in hole with rose reamer on the existing drilling machine of effectively solving according to orifice chamfer device of the present utility model
The ever-present problem for frequently switching on equipment, significantly improves working (machining) efficiency during the chamfering of side, is provided simultaneously with compact conformation, is easy to
The features such as manipulation, widely applicable and high precision, it is therefore particularly suitable for the inner side chamfering application scenario of valve body and similar parts etc.
As it will be easily appreciated by one skilled in the art that preferred embodiment of the present utility model is the foregoing is only, not
To limit this utility model, all any modifications made within spirit of the present utility model and principle, equivalent and change
Enter, should be included within protection domain of the present utility model.
