Description
Technical field
The utility model belongs to hand-operated tools technical field, and in particular to a kind of numerical control strong handle of a knife dismantling spanner.
Background technology
Numerical control strong handle of a knife is the handle of a knife commonly used in machining, for the clamping of the staight shank cutter such as milling cutter, reamer, jump ring
Pinching deformation is small, and chucking power is bigger, and rigidity is good, and clamping accuracy is higher, can change different collet chucks to clamp different handles
The milling cutter in footpath, reamer etc., because its characteristic has a wide range of applications in Digit Control Machine Tool.Yet with the versatility of handle of a knife, need frequent
Tool changing is dismantled, existing numerical control strong handle of a knife extracting tool is common C-shaped spanner, and C-shaped spanner latch part is easy to wear during use,
Spanner working portion fails, and easily skids, and damages handle of a knife, safe operation poor reliability.Therefore, it is firm that a kind of positioning need to be sought
It is accurate to be not easy skid abrasion, the convenient numerical control strong handle of a knife tool special for dismounting of execute-in-place.
The content of the invention
To be solved in the utility model is that existing numerical control strong handle of a knife dismantling spanner easily skids, damages handle of a knife, operation peace
The technical problem of full poor reliability, there is provided a kind of numerical control strong handle of a knife dismantling spanner,
In order to solve technical problem of the present utility model, the utility model is achieved through the following technical solutions：It is a kind of
Numerical control strong handle of a knife dismantling spanner, including O shapes dismantling spanner and locating piece, O shapes dismantling spanner front end endoporus are ellipse,
The endoporus upper top is provided with latch boss, and the endoporus lower bottom part is provided with groove, and the O shapes dismantling spanner rear end is circular hand
Handle；The locating piece is T-type structure, and the locating piece is provided with locating piece boss, and the locating piece is fixed on the O shapes dismounting
In the groove of spanner.The latch boss is working portion, is positioned simultaneously by the latch boss and the locating piece boss
Use, the technical problem for the abrasion that effectively solves to skid caused by spanner screens is not tight, instrument with handle of a knife accurate positioning, firmly.
Compared with prior art, the beneficial effect of the utility model acquisition is：
A kind of numerical control strong handle of a knife dismantling spanner, is set using latch boss and locating piece boss disclosed in the utility model
Meter, the technical problem for the abrasion that effectively solves to skid caused by spanner screens is not tight, instrument with handle of a knife accurate positioning, firmly.This reality
It is simple in construction, be skillfully constructed with a kind of new disclosed numerical control strong handle of a knife dismantling spanner, easy-to-operate during use, tool
There is very strong practicality.

Embodiment
Below in conjunction with the accompanying drawings, embodiment is described in detail.
Referring to accompanying drawing 1 and accompanying drawing 6, a kind of numerical control strong handle of a knife dismantling spanner, including O shapes dismantling spanner 1 and locating piece 2,
The front end endoporus of O shapes dismantling spanner 1 is ellipse, and the endoporus upper top is provided with latch boss 7, and the endoporus lower bottom part is set
Fluted 8, the rear end of O shapes dismantling spanner 1 is round handle；The locating piece 2 is T-type structure, and the locating piece 2 is provided with
Locating piece boss 9, the locating piece 2 are fixed in the groove 9 of the O shapes dismantling spanner 1.The latch boss 7 is work department
Point, use is positioned by the latch boss 7 and the locating piece boss 9 simultaneously, caused by effective solution spanner screens is not tight
Skid the technical problem of abrasion, instrument and handle of a knife accurate positioning, firmly.
The latch boss 7 of O shapes dismantling spanner 1 matches with the collar neck B13 on the collar 3, and locating piece 2 inserts the dismounting of O shapes
In the groove 8 of spanner 1, locating piece boss 9 is bonded with collar neck A12.
Implementation process：Handle of a knife 4 is removed from Digit Control Machine Tool, the back-off of handle of a knife 4 is inserted into a with holes and bottom plate for positioning boss 5
In hole, the handle of a knife fluting 10 on handle of a knife 4 is caught in the bottom plate boss 11 of bottom plate 5, and O shapes dismantling spanner 1 is enclosed on handle of a knife 4 from top to bottom
The collar 3 on, the cutter 6 is fixed in the collar 3, and the latch boss 7 of O shapes dismantling spanner 1 is embedded in the collar neck on the collar 3
In B13, locating piece 2 is placed in the groove 8 of the root of O shapes spanner 1, and locating piece boss 9 is embedded in the collar neck on the collar 3
In A12, the dismounting and tool changing of handle of a knife 4 can be completed by applying external force to the tail handle of O shapes dismantling spanner 1.
Listed above is only one of specific embodiment of the utility model.Obviously, the utility model is not limited to above reality
Example is applied, there can also be many similar reshapings.One of ordinary skill in the art can be direct from the utility model disclosure
All deformations for exporting or associating, are considered as the utility model scope of the claimed.
