Abstract
The utility model relates to an internal expansion type workpiece clamping mechanism, which comprises a workpiece clamping block. The utility model has main points that the internal expansion type workpiece clamping mechanism is provided with a supporting frame for a clamping block and a transmission mechanism which leads the supporting frame for a clamping block to ascend and descend. The utility model can clamp workpieces through a pipe of a pipe fitting, and can be used for clamping pipe fittings with pipe mouths with larger diameters, with the advantages of simple structure and small volume.
Description
The utility model relates to a kind of internal expanding type workpiece grip mechanism.
In the prior art, external clamping mechanism is generally adopted in the clamping of workpiece especially pipeline.Promptly allow workpiece grip mechanism moving fixture block and decide fixture block with the clamping of therebetween workpiece.But for the bigger pipeline of nozzle diameter, above-mentioned external clamping mechanism just must do big or even complicated structure.
The purpose of this utility model is to provide a kind of volume less, the better simply internal expanding type workpiece grip mechanism of structure.
The technical solution of the utility model is: a kind of internal expanding type workpiece grip mechanism, comprise the workpiece fixture block, its key be provided with an axis and with the dead axle cover of axis thread connection, one end dead axle of axis puts to be arranged with axis makes axially movable moving axis cover, is provided with the retainer that a restriction moving axis cover rotates between moving axis cover and the dead axle cover; Be provided with fixture block and support thereof more than three groups or three groups, the fixture block support is made of two rod members that are hinged at the middle part, and a rod member one end and moving axis cover are hinged, and the other end and workpiece fixture block are hinged, another rod member one end and dead axle cover are hinged, and the other end is hinged with the bearing pin that is located in the workpiece fixture block guide groove.
The longitudinal section of above-mentioned axis is the T type, and the moving axis cover has space corresponding with it and that axis is rotated therein.
Above-mentioned fixture block and support thereof are three groups, evenly distribute around axis.
When the utility model uses, clamping device is stretched in the pipe, because axis connects with the dead axle external threading, the dead axle cover is motionless during rotating middle shaft, then axis drives the motion of moving axis cover, and because of retainer has limited the rotation that moving axis overlaps, this moment, the moving axis cover can only move axially, two rod members of fixture block support rotate in opposite directions around its middle part pin joint under the effect of moving axis cover, thereby realize clamping or the purpose of unclamping workpiece.The utility model is not only simple in structure, volume is little, and in the pipe of pipe fitting holding workpiece, can be used for the clamping of the bigger pipe fitting of nozzle diameter.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
As shown in drawings, the utility model be provided with an axis 1 and with the dead axle cover 2 of axis 1 thread connection, on the end dead axle cover 2 of axis 1, be arranged with and make axially movable moving axis cover 3, be provided with restriction moving axis cover 3 retainers that rotate 4 between moving axis cover 3 and the dead axle cover 2 with axis 1; Be provided with fixture block 5 and support 6 thereof more than three groups or three groups, fixture block support 6 is made of two rod members 7,8 that are hinged at the middle part, it is 3 hinged that one rod member, 7 one ends and moving axis overlap, the other end and workpiece fixture block 5 are hinged, it is 2 hinged that another rod member 8 one ends and dead axle overlap, and the other end is hinged with the bearing pin 10 that is located in the workpiece fixture block guide groove 9, when rod member 8,9 when middle part pin joint 11 rotates, bearing pin 10 moves in guide groove 9, and fixture block support 6 drives fixture block 5 clampings or unclamps workpiece like this.
Axis of the present utility model longitudinal section can be the T type, and the moving axis cover has space corresponding with it and that axis is rotated therein, overlaps reciprocating vertically so that axis drives moving axis.Can certainly adopt other form to realize the transmission of above-mentioned motion, connect as axis is overlapped with moving axis by bearing.
Fixture block of the present utility model and support thereof can or be organized for three groups more, are good with three groups, preferably evenly distribute around axis.
Claims (3)
1, a kind of internal expanding type workpiece grip mechanism, comprise the workpiece fixture block, it is characterized in that being provided with an axis and with the dead axle cover of axis thread connection, one end dead axle of axis puts to be arranged with axis makes axially movable moving axis cover, is provided with the retainer that a restriction moving axis cover rotates between moving axis cover and the dead axle cover; Be provided with fixture block and support thereof more than three groups or three groups, the fixture block support is made of two rod members that are hinged at the middle part, and a rod member one end and moving axis cover are hinged, and the other end and workpiece fixture block are hinged, another rod member one end and dead axle cover are hinged, and the other end is hinged with the bearing pin that is located in the workpiece fixture block guide groove.
2, clamping device according to claim 1 is characterized in that the longitudinal section of axis is the T type, and the moving axis cover has space corresponding with it and that axis is rotated therein.
