Abstract
The invention relates to a collapsible power assembly for a coiler mandrel. The collapsible power assembly comprises a pull rod 8 installed in shaft holes of a main shaft 6, a collapsible oil cylinder 9 connected with the main shaft 6 to form a whole body, and a rotating connector 10 installed on the side end face of the main shaft 6 on the back of the collapsible oil cylinder 9. A first shaft hole 71, a second shaft hole 72 and a third shaft hole 73 are respectively formed in the main shaft 6 from the collapsible oil cylinder 8 to the rotating connector 10. The third shaft hole 73 serves as an oil chamber of the collapsible oil cylinder 9. The oil chamber of the collapsible oil cylinder 9 is internally provided with a piston 11. A through hole through which the pull rod 8 penetrates is formed in the center of the piston 11. A bottom cover 61 of the collapsible oil cylinder 9 is fixedly installed on the end face, facing to the rotating connector 10, of the main shaft 6 by a bolt. The rotating connector 10 is coaxially fixed on the bottom cover 61 through a bolt. The axial length of the pull rod and the piston is greatly shortened, so that the overall axial length of the collapsible power assembly for the coiler mandrel is shortened, the parts are reduced, and the structure is simplified. Therefore, the connection between a compressing nut and the pull rod is effectively prevented from loosening.
Description
Technical field
The present invention relates to a kind of coiler mandrel, particularly a kind of harmomegathus power assembly for coiler mandrel.
Background technology
The structure of existing coiler mandrel harmomegathus power assembly as shown in Figure 1, comprise pull bar 2, harmomegathus oil cylinder 3 and the swivel joint 4 coaxial with main shaft 1, swivel joint 4 is fixedly mounted on the end face of harmomegathus oil cylinder 3 back of the body main shafts 1 side, the supply of control harmomegathus oil cylinder 3 interior hydraulic oil, can axially move back and forth along main shaft 1 so that be positioned at the piston 5 of harmomegathus oil cylinder 3 oil pockets, the bar section of piston 5 is connected with the pull bar 2 that is positioned at main shaft 1 axis hole by connector 51, pull bar 2 drives the motion of associated components again, finally realizes the harmomegathus of coiler mandrel.
There is following shortcoming in this coiler mandrel harmomegathus power assembly: for the bar section that allows pull bar 2 be connected with the harmomegathus oil cylinder piston connects by connector 51, pull bar 2 must stretch out main shaft 1 one segment distances, with the position that provides to be connected with piston 5 bar sections, so just increase the axial dimension of harmomegathus power assembly, can not adapt to part steel mill to the axial installing space of coiler mandrel harshness; Be subject to ectocine for fear of this connecting portion in addition, need to be at sleeve 52 of outer setting of this connecting portion, while protecgulum 53 of coaxial fixed installation on the end face of main shaft 1, so that sleeve 52 can be welded on this protecgulum 53, the other end of sleeve 52 is welded with a bonnet 54, as the mounting seat of the bottom 31 of harmomegathus oil cylinder 3, the parts of coiler mandrel harmomegathus power assembly have so just been increased, so that its complicated structure.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, and provide a kind of whole axial length the harmomegathus power assembly that is used for coiler mandrel little, simple in structure.
Technical scheme of the present invention is: a kind of harmomegathus power assembly for coiler mandrel, comprise be positioned at spindle hole of main, can be along the pull bar of main shaft axially-movable, be provided with the harmomegathus oil cylinder of piston in, the oil pocket coaxial with main shaft, with be fixed on harmomegathus oil cylinder back of the body main shaft side end face, be the swivel joint of harmomegathus oil cylinder fuel feeding, described pull bar is fixedly connected with piston; Described spindle hole of main is stepped that diameter increases gradually towards the swivel joint direction, be divided into successively and hold most the first axis hole of pull bar and the second axis hole, reach the Triaxial hole as the oil pocket of described harmomegathus oil cylinder, be provided with lining in the second axis hole, described lining and the second axis hole interference fit are with the pull bar matched in clearance; Main shaft is equipped with harmomegathus oil cylinder bottom towards the end face of swivel joint one end; The described piston that is positioned at harmomegathus oil cylinder oil pocket only has head, and the central authorities of piston have the through hole that passes for pull bar, and described piston is fixed on the pull bar with securing member.
Adopt technique scheme of the present invention, because the oil pocket of harmomegathus oil cylinder is the Triaxial hole of main shaft, so pull bar does not need to reach outside the main shaft, the axial length of pull bar can shorten, and piston only has head, does not have bar section, and the axial length of piston has also shortened; And because the central authorities of piston have through hole, and pull bar can pass piston, the distance that this has further shortened again between pull bar and the piston has reduced the whole axial length of harmomegathus power assembly of coiler mandrel.In addition, the connecting portion of pull bar of the present invention and piston is located immediately in the oil pocket of harmomegathus oil cylinder, the miscellaneous parts such as sleeve needn't be set again protect connecting portion, has reduced parts, has simplified structure.
The further technical scheme of the present invention is: the described securing member that pull bar is fixed to piston is the clamp nut with internal thread, described pull bar has the external screw thread that is threaded with clamp nut near the end outer circumference surface of swivel joint, has towards swivel joint on the described pull bar excircle, is adjacent to the annular stepped face of plunger backer swivel joint end face.
Adopt technique scheme of the present invention, the end face of plunger backer swivel joint is pressed on the annular stepped face of pull bar, piston is then compressed by clamp nut towards the end face of swivel joint, piston can well be fixed on the pull bar, is threaded simultaneously also for convenience detach.
The present invention further technical scheme is: described piston is provided with a diameter greater than the circular blind hole of through hole towards the end face central authorities of swivel joint, and clamp nut is adjacent to the bottom surface of described circular blind hole.
Adopt technique scheme of the present invention, because piston is provided with a diameter greater than the circular blind hole of through hole towards swivel joint end face central authorities, clamp nut is pressed on the bottom surface of described circular blind hole, the connecting portion of clamp nut and pull bar is in the inside of piston like this, reduced taking harmomegathus oil cylinder volume, the volume of corresponding harmomegathus oil cylinder can dwindle, the axial length that is to say the harmomegathus oil cylinder can further reduce, and correspondingly the whole axial length of coiler mandrel harmomegathus power assembly also can reduce.
The present invention further technical scheme is: pull bar is fixed with anti-loose spot towards the end face of swivel joint, and described anti-loose spot covers clamp nut at least towards the part end face of swivel joint.
Adopt this technical scheme, because the existence of anti-loose spot, clamp nut will be restricted by the axial float of the excessive generation of axial force, prevents that clamp nut and being connected of pull bar from occurring loosening.
