Preferably, described the first slide unit comprises one first flat board, and is arranged on four the first rollers of the described first dull and stereotyped below, and two one group, described four the first rollers, coordinate with described guide rail respectively.
Preferably, the bottom of described bracket connects described the first flat board by a plane bearing.Owing to using described plane bearing by described bracket and the described first dull and stereotyped connection, the rotation that described support component can be spent around the axis of described plane bearing 360, described support component can move along described guide rail simultaneously.
Preferably, described guide rail is laid along the direction vertical with described to be processed axis direction.
Preferably, described the second slide unit comprises the second flat board, and is arranged on four the second rollers of the described second dull and stereotyped below, and described four the second rollers can roll on described table top.
Preferably, described extensible member comprises four poles and four adjustable anchor bolts, and one end of each described pole is welded on described table top bottom, the other end of each described pole and the welding of described adjustable anchor bolt.This just makes described upper bracket and the described medium-height trestle can maintenance level and the height of adjustable described rolled thread dynamic poise device, makes the axial line height of to be processed consistent with the axial line height of cylindrical die roll.
The utility model also provides a kind of screw-rolling machine, and it comprises bolt rolled thread dynamic poise device as above.
Positive progressive effect of the present utility model is: can continue to provide support to workpiece, and reduce the resistance in rolled thread process.

Detailed description of the invention
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
Embodiment 1
Understood incorporated by reference to Fig. 1, the utility model provides a kind of bolt rolled thread dynamic poise device, and for supporting to be processed 4, described bolt rolled thread dynamic poise device comprises upper bracket 1, medium-height trestle 2 and lower carriage 3.Described upper bracket 1 comprises: be resisted against described to be processed 4 bottoms, and can rotate to reduce resistance between to be processed 4 and cylindrical die roll 4 support components that play effective support to machined part with to be processed 4.Described support component comprises 11 two one group of four support wheels 11 and 12, four support wheel of bracket, is fixedly connected on described bracket 12, and lays respectively to be processed 4 both sides.The axis of four support wheels 11 is parallel with the axis of to be processed 4.First dull and stereotyped 14 forms the first slide unit with four the first rollers 15 that are fixed on the first dull and stereotyped 14 belows.The bottom of bracket 12 is fixedly connected on the top of plane bearing 13, and the bottom of plane bearing 13 is fixedly connected on the first flat board 14, and this can freely swing with to be processed 4 support component in horizontal plane, therefore can continue 4 to provide support to machined part.To sum up, upper bracket 1 can be to machined part 4 provides and continues support and reduce to be processed 4 resistance that rotates, swings at horizontal plane generation because of self.Medium-height trestle 2 comprises guide rail 21, four the second rollers 22, one second flat board 23, and guide rail 21 is laid on the second flat board 23, and four the second rollers 22 are arranged on the below of the second flat board 23.Guide rail 21 matches with the first roller 15, and the first roller 15 can be moved along guide rail 21.The second roller 22 can move along the direction consistent with to be processed 4 axis direction.Lower carriage 3 comprises and carries the table top 31 of described the second roller 22 and be connected with described table top 31 and the extensible member of adjustable this table top 31 height, described extensible member comprises four adjustable anchor bolts 32, four poles 33, each pole 33 one end are welded on table top 31 bottoms, and the other end of pole 33 and an adjustable anchor bolt 32 weld.By adjustable anchor bolt 32, the function that described lower carriage 3 is realized is the height that makes described upper bracket 1 and described medium-height trestle 2 maintenance levels adjustable described bolt rolled thread dynamic poise device, makes the axial line height of described to be processed 4 consistent with the axial line height of cylindrical die roll.
