Description
Technical field
The utility model is related to drill jig technical field, especially relates to a kind of not parking formula drill jig.
Background technology
In mechanical processing process, drilling, tapping, reaming, fraising are common processing technologys, need in process many
Plant cutter dop.If should be drilled in a working face, reamed again, while the multiple operation such as tapping adds again
In the case of work, before operating personnel can only enter next procedure a procedure is completed, stopping to unload has completed work
Cutter, work of being driven after replacing with the cutter of next procedure again.So frequently stop, the secondary process time had both been increased, reduce
Labor productivity, increased labor strength again.
Content of the invention
The purpose of this utility model is to avoid the defect of prior art and provide a kind of not parking formula drill jig, effectively
Solve the problems, such as prior art.
For achieving the above object, the technical scheme that the utility model is taken is：Described a kind of not parking formula drill jig,
The clamp body for including to be connected with machine tool chief axis is characterized in, the base of tool is provided with described fixture body, on the side wall of clamp body
Cross and be provided with one group of steel ball hole, steel ball in the hole is provided with torque steel ball, be cased with axial direction moving outside clamp body from
Trap, clutch cover top are provided with the limited block with clamp body outer wall surface fit depressions, solid by pin in the described base of tool
Dingan County is equipped with moment of torsion block, and cutter upper end is connected with moment of torsion block, and cutter lower end is fixedly mounted on below the base of tool by marking closely screw
In the hole, base of tool bottom is provided with radial ball bearing.
The surface that the external diameter of the described base of tool is coordinated with clamp body is correspondingly arranged on steel ball nest, torque steel with torque steel ball
Ball enters the base of tool by the effect of clutch cover gravity, so that the base of tool is connected with clamp body.
By the small ball empty set in clamp body outer wall groove on clamp body, clutch cover bottom is inner cone to described clutch cover
Torque steel ball is tightly pushed down by structure, clutch cover inner surface under gravity.
There is groove that is chimeric with cutter and being easy to transmitting torque below described moment of torsion block.
Described radial ball bearing inner ring and clamp body synchronous axial system, radial ball bearing inner ring pass through shaft shoulder axially position simultaneously
Fastened by nut.
The beneficial effects of the utility model are：Described a kind of not parking formula drill jig, its simple structure, user
Just, reliable operation, can carry out the fixture of cutter changing in the case of not parking.
Description of the drawings
Fig. 1 is the utility model structural representation.
Shown in figure：1. clamp body；2. clutch cover；3. the base of tool；4. torque steel ball；5. moment of torsion block；6. holding screw；7.
Radial ball bearing；8. nut；9. small ball；10. limited block；11. pins；12. cutters.
Specific embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
New, it is not intended to limit scope of the present utility model.
As shown in figure 1, described a kind of not parking formula drill jig, is characterized in the fixture for including to be connected with machine tool chief axis
Body 1, is provided with the base of tool 3 in described clamp body 1, crosses and be provided with one group of steel ball hole on the side wall of clamp body 1, and steel ball in the hole is pacified
Equipped with torque steel ball 4, the clutch cover 2 that in axial direction can be moved outside clamp body 1, is arranged with, 2 top of clutch cover is provided with and folder
The limited block 10 of concrete 1 outer wall surface fit depressions, is installed with moment of torsion block 5, knife by pin 11 in the described base of tool 3
Have 12 upper ends to be connected with moment of torsion block 5,12 lower end of cutter is fixedly mounted on the in the hole of 3 lower section of the base of tool, cutter by marking closely screw 6
3 bottoms of seat are provided with radial ball bearing 7.
Further, the surface that the external diameter of the described base of tool 3 is coordinated with clamp body 1 is correspondingly arranged on steel with torque steel ball 4
Pearl nest, torque steel ball 4 enter the base of tool 3 by the pressure effect of 2 gravity of clutch cover, so that the base of tool 3 is connected with clamp body 1.
Further, described clutch cover is by the small ball empty set in clamp body outer wall groove on clamp body, under clutch cover
Portion is inner cone structure, and torque steel ball is tightly pushed down by clutch cover inner surface under gravity.
Further, there is groove that is chimeric with cutter 12 and being easy to transmitting torque described 5 lower section of moment of torsion block.
Further, described 7 inner ring of radial ball bearing and 1 synchronous axial system of clamp body, 7 inner ring of radial ball bearing pass through the shaft shoulder
Axially position is simultaneously fastened by nut 8.
Described a kind of not parking formula drill jig, during use, when the work of cutter 12 completes to enter next procedure,
Workman's left hand is held clutch cover 2 and is moved up, and the right hand is held 7 outer ring of radial ball bearing and prepares to remove fixture, now torque steel
Ball 4 is no longer acted on by 2 gravity of clutch cover, and torque steel ball 4 departs from the base of tool 3 under the influence of centrifugal force, and the base of tool 3 is from fixture
Separate in body 1 and removed by workman.When installing new fixture, workman's hand holds 7 outer ring of radial ball bearing by the new base of tool 3 again
Load in clamp body 1, and clutch cover 2 is unclamped, allow which to fall and be pressed on torque steel ball 4 so as to reenter the knife on new clothes
In the steel ball nest of tool seat, now under the packing interaction of torque steel ball, so that clamp body 1 is reconnected with the base of tool 3 and while turn
Dynamic, now enter working condition.7 outer ring of radial ball bearing is mutually moved with respect to inner ring, in loading and unloading clamp by workman's hand
Frictional force makes outer ring static, mainly avoids workman from being abraded by the inertia force of fixture.
Preferred embodiment of the present utility model is the foregoing is only, not in order to limit the utility model, all in this practicality
Within new spirit and principle, any modification, equivalent substitution and improvement that is made etc., should be included in guarantor of the present utility model
Within the scope of shield.
