Abstract
The utility model discloses an interior expanding location locking mechanism, including the cutter connecting piece, the lower extreme is inside in the cutter connecting piece offers counter bore and pore forming cylinder barrel and establishes the cylinder cylinder cap at terminal surface down, and piston in the cylinder barrel passes the cylinder cylinder cap downwards and at the end -to -end connection teper -shank that leads, cylinder cylinder cap lower extreme downwardly extending forms petal type elastic taper sleeve, and during the piston upward movement, the direction teper -shank is ab intra with the petal type elastic taper sleeve distending. The beneficial effects of the utility model are that: need working space little, and the installation is dismantled all simple and efficiently, but convenient and fast ground is automatic to the heart with the machining tool and the axle center of pipe fitting, need not carry out loaded down with trivial details debugging.
Description
Technical field
The utility model is related to a kind of internal-expansion type location locking mechanism, and the positioning for pipe machining tool is clamped, and is belonged to
Pipe machining tool technical field.
Background technology
Existing hollow pipe fitting location locking mechanism typically all using outside clamping mode, the working space of occupancy it is larger and
Installing/dismounting is not convenient, working space it is narrow and pipe fitting be in it is immovable in the case of be difficult to play a role.Moreover,
Most of pipe fitting positioning and clamping mechanism now is all only applicable to the pipe fitting of outer surface rule, irregular for external surface shape,
As having a case that then clamping effect is unsatisfactory compared with multi-step, or even can not use at all.
Utility model content
Goal of the invention of the present utility model is：For above-mentioned problem, there is provided a kind of internal-expansion type positioning and locking machine
Structure, easily and reliably positioning and locking on pipe fitting, without being limited by pipe fitting outer wall shape, can be suitable for hollow pipe fitting
The occasion that outer wall is processed.
The technical solution adopted in the utility model is such：
A kind of internal-expansion type location locking mechanism, including tool coupling, open up heavy in the tool coupling inside lower end
Hole and stomatal limiting value cylinder barrel simultaneously set cylinder head in lower surface, and the piston in cylinder barrel is passed down through cylinder head and at end
End connection is oriented to taper shank, and the cylinder head lower end extends downwardly and forms petal type elastic conical drogue, during piston upwards, leads
To taper shank from inside by petal type elastic conical drogue distending.
Preferably, the tool coupling top opens up counterbore.After opening up counterbore, drive the motor that cutter is rotated with
And corresponding position can just be inserted the counterbore by the part of each cutter of connection, axially position is realized, and no longer needed to use another
Outer parts.
Preferably, setting spline on the tool coupling outer wall as a splined shaft.Tool coupling is set
Into after the form of splined shaft, the parts being directly connected with cutter can then be arranged to the form of spline housing, so that cutter
Strictly according to pipe fitting endoporus center for axle center is rotated, it is ensured that the machining accuracy of pipe fitting outer wall.
Preferably, the cylinder head is provided with for detecting that whether what is be installed in place between cylinder head and pipe fitting arrives
Position detection switch.
In sum, by adopting the above-described technical solution, the beneficial effects of the utility model are：Need working space
It is small, and installing/dismounting is all simple and efficient；Can conveniently and efficiently by machining tool and the axle center automatic centering of pipe fitting, it is not necessary to carry out
Cumbersome debugging；Positioning and locking is carried out using the endoporus of pipe fitting, is not limited by pipe fitting outer wall shape, the pipe fitting being suitable for is more
It is many；Real-time Monitoring Data can be in time fed back, positioning and locking process visualization is allowed.
Brief description of the drawings
Fig. 1 is main view profile of the present utility model.
Marked in figure：1 is tool coupling, and 2 is piston, and 3 is detection switch in place, and 4 is cylinder head, and 5 is guide cone
Handle, 6 is pipe fitting.
Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
Embodiment：
As shown in figure 1, a kind of internal-expansion type location locking mechanism, including tool coupling 1, in the tool coupling 1 under
End is internal to be opened up counterbore and stomatal limiting value cylinder barrel and sets cylinder head 4 in lower surface, and the piston 2 in cylinder barrel is passed down through
Cylinder head 4 simultaneously connects guiding taper shank 5 in end, and the lower end of the cylinder head 4 extends downwardly and forms petal type elastic conical drogue,
When piston 2 is moved upwards, taper shank 5 is oriented to from inside by petal type elastic conical drogue distending.
The top of the tool coupling 1 opens up counterbore.Spline is set on the outer wall of the tool coupling 1 used as a spline
Axle.Whether the cylinder head 4 is provided with for detecting the detection switch in place being installed in place between cylinder head 4 and pipe fitting 6
3.In cylinder head 4, some detection switch 3 in place are set at equal intervals.
In installation of the present utility model and the course of work, detection switch 3 can real-time monitoring peace of the present utility model in place
The petal type elastic conical drogue inner conical surface for one's heart's content being detected during condition and feedback operation and the pressure size being oriented between taper shank 5,
It is fed back on display device, realizes the visualization of installation locking process.
Specific works mode of the present utility model is：After the utility model is installed, the stomata on the outside of cylinder barrel enters
Gas, inner side stomata outlet makes piston 2 move upwards, so as to drive guiding taper shank 5 to move upwards, makes the conical surface pair of guiding taper shank 5
The petal type elastic conical drogue of the bottom of cylinder head 4 is extruded, and makes that petal type elastic conical drogue is outer swollen to be reached so as to extrude the inwall of pipe fitting 6
To locking and automatic centering；Cylinder barrel inner side stomata air inlet, outside stomata outlet moves downward piston 2, so that band action-oriented
Taper shank 5 is moved downward, and separates petal type elastic conical drogue of the conical surface of guiding taper shank 5 gradually with the bottom of cylinder head 4, petal type
Elastic conical drogue rebounds, the inwall of no longer outer swollen extruding pipe fitting 6, so as to be unclamped by locking state.
