Specifically, the connection between the first screw and the support block may be as follows: the supporting block is provided with a first screw mounting hole along the radial direction of the annular cover plate, a pin shaft mounting hole is formed along the circumferential direction of the annular cover plate, and the first screw extends into the first screw mounting hole and is fixed with the supporting block through an anti-falling pin shaft penetrating through the pin shaft mounting hole.
Specifically, the connection between the second screw and the connecting plate may be as follows: the connecting plate includes integrated into one piece's insertion portion and supporting part, and the second screw rod inserts in the insertion portion and fixed through anticreep round pin axle, and the supporting part is the arc structure that suits with the second work piece inner wall.
Furthermore, two operation surfaces are milled on the outer wall of the thread sleeve.
Beneficial effects of the utility model
A device for jacking and supporting two concentric thin-wall workpieces has the following characteristics:
1. the structure is simple, and the disassembly, assembly and adjustment are convenient;
2. the operation is stable and reliable, and self-locking can be realized;
3. the space is saved;
4. the two thin-wall workpieces can be kept concentric by adjusting the supporting and adjusting mechanism, and the later-stage processing is facilitated.

FIG. 1 is a schematic diagram of the system of the present invention;
in the figure, 1, an annular cover plate, 2, a supporting block, 3, a first screw rod, 4, a thread bush, 5, an operation surface, 6, a second screw rod, 7, a supporting part, 8, an inserting part, 9, an anti-dropping pin shaft and 10, a pin shaft mounting hole are arranged.
Detailed Description
The utility model provides a device for jack-up supports two concentric thin wall work pieces, it includes annular apron 1 and supports adjustment mechanism, annular apron's lower surface has a plurality of supporting shoes 2 along outer fringe fixed mounting, first work piece outer wall is hugged closely to the supporting shoe inboard, it includes first screw rod 3 to support adjustment mechanism, second screw rod 6 and suit are in thread bush 4 between first screw rod and second screw rod, the one end that first screw rod and second screw rod correspond is equipped with the external screw thread that revolves to opposite respectively, the thread bush is equipped with the internal thread with the external screw thread assorted of first screw rod and second screw rod, the outer end and the supporting shoe fixed connection of first screw rod, the outer tip fixed mounting of second screw rod has the connecting plate.
Specifically, the connection between the first screw and the support block may be as follows: first screw rod mounting hole (not shown) has been seted up along annular apron radial direction on the supporting shoe, has seted up round pin axle mounting hole 10 along annular apron circumferential direction, and first screw rod stretches into in the first screw rod mounting hole to it is fixed with the supporting shoe through the anticreep round pin axle 9 that passes the round pin axle mounting hole, makes things convenient for the dismouting between first screw rod and the supporting shoe, and prevents that first screw rod from taking place relative rotation for the supporting shoe.
Specifically, the connection between the second screw and the connecting plate may be as follows: the connecting plate includes integrated into one piece's insertion portion 8 and supporting part 7, and the second screw rod inserts in the insertion portion and through anticreep round pin hub fixation, and the supporting part is the arc structure that suits with the second work piece inner wall, makes things convenient for the dismouting between second screw rod and the connecting plate to prevent that first screw rod from taking place relative rotation for the connecting plate, increased the area of contact of connecting plate with second work piece inner wall simultaneously, make the support more firm reliable.
Furthermore, two operation surfaces 5 are milled on the outer wall of the threaded sleeve, so that the threaded sleeve can be rotated by using a tool conveniently.
The utility model discloses a device for jack-up supports two concentric thin wall work pieces, when treating two thin wall shape work pieces of processing, like the thin wall pipe, the ring or be similar to the pipe, the work piece of ring, and when the diameter size is different, can fix the less work piece of diameter with anchor clamps, then place the annular apron in the device in the top of this work piece, a plurality of supporting shoes of annular apron lower surface are pasted tightly with the outer wall of this work piece, then the nut cover of rotatory support adjustment mechanism, it is flexible to make the second screw rod drive the connecting plate, thereby make the connecting plate tightly support the great work piece inner wall of diameter, as long as make every length that supports adjustment mechanism equal, just can guarantee that two thin wall work pieces keep concentric.
