Abstract
The utility model relates to a cylindrical shell section aligning device, which comprises a base. The device is structurally characterized in that a cross arm is mounted above the base, the length of the cross arm is identical to that of the base, and the cross arm and the base are fixed together at one end and spaced at the other end; two press oil cylinders are arranged at the unconnected end of the cross arm, and two ejection oil cylinders are arranged at the unconnected end of the base; the press oil cylinders and the ejection oil cylinders are longitudinally arranged along the cross arm and the base respectively, and the end parts of the piston rods of the two press oil cylinders correspond to those of the piston rods of the two ejection oil cylinders; and space is reserved between the end parts of the piston rods of the press oil cylinders and those of the piston rods of the ejection oil cylinders when the piston rods are retracted. The cylindrical shell section aligning device used for the welding of cylindrical shell sections can achieve the aligning of the mouth parts of two cylindrical shell sections, so as to guarantee the welded quality of assembly points. The device is applicable to the aligning of sections during the welding of cylindrical workpieces.
Description
Technical field
The utility model relates to a kind of welding support.Specifically, be that the cylindrical workpiece welding time is used for the device that the envoy aligns with internode.
Background technology
All know at welding profession, to the welding of large diameter tubular workpiece joint with internode, need by can height, the support envoy of left and right adjusting aligns with internode.Conventional stent comprises base, and four wheel seats and roller are arranged on each base.During welding, two shell rings are placed on respectively between four wheel seats and roller of two supports, by regulating the relative position between two wheel seats and the roller, thereby realize about the shell ring on the support, left and right sides position adjustments, a shell ring oral area on the support is alignd with shell ring oral area on another support.But for the bigger shell ring of diameter, because its deadweight factor such as heavier is the level of state again when it places on the support, its interface often is ellipticity.Therefore, only regulate, be difficult to make the oral area alignment of two shell rings, can't guarantee the welding quality of assembly unit point by the roller under the shell ring.
The utility model content
Problem to be solved in the utility model provides a kind of shell ring contra-aperture device.Adopt this shell ring contra-aperture device that shell ring is welded, can make the oral area alignment of two shell rings, guarantee the welding quality of assembly unit point.
For addressing the above problem, take following technical scheme:
Shell ring contra-aperture device of the present utility model contains base, and its design feature is that the base top has transverse arm, is fixed together between the length of transverse arm and the equal in length of base and their end, leaves spacing between their other end.Two down pressing oil cylinder are arranged on the front of motor of transverse arm, have two to go up the top oil cylinder on the front of motor of base.Described down pressing oil cylinder and last top oil cylinder be respectively along vertical layout of transverse arm and base, and corresponding between the piston rod end of two down pressing oil cylinder and two piston rod ends of going up the top oil cylinders.When the piston rod indentation, also leave spacing between the piston rod end of the piston rod end of down pressing oil cylinder and last top oil cylinder.
Further improvement of the utility model is, between an end of transverse arm and base Connection Block arranged, and is fixed together by this Connection Block between an end of transverse arm and base.
Of the present utility model further the improvement be, on four jiaos of the lower surfaces of base roller arranged all, under this roller guide rail arranged.
Take such scheme, have the following advantages:
By such scheme as can be seen,, be fixed together between an end of transverse arm and base, leave spacing between their other end and be separately installed with two down pressing oil cylinder and two last top oil cylinders because there is transverse arm the base top.Described down pressing oil cylinder and last top oil cylinder be respectively along vertical layout of transverse arm and base, and corresponding between the piston rod end of two down pressing oil cylinder and two piston rod ends of going up the top oil cylinders.When the piston rod indentation, also leave spacing between the piston rod end of the piston rod end of down pressing oil cylinder and last top oil cylinder.When two shell rings are connect welding, shell ring is enclosed within the outside of transverse arm and an end bottom of this shell ring is placed between the last top oil cylinder of the down pressing oil cylinder of transverse arm inboard and base inboard, and another shell ring then places between the last top oil cylinder of the down pressing oil cylinder in the transverse arm outside and chassis outer side the bottom of one end by movable supporting frame.When shell ring because its deadweight factor such as heavier, when the ellipticity situation appears in its interface, flexible by the piston rod of down pressing oil cylinder and last top oil cylinder, can make the oral area alignment of two shell rings, guarantee the welding quality of assembly unit point
Description of drawings
Fig. 1 is a shell ring contra-aperture device structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, shell ring contra-aperture device of the present utility model contains base 9, and this base is a cuboid, and its top is provided with transverse arm 5.The equal in length of the length of described transverse arm 5 and base 9 is provided with a Connection Block 4 between their end, be fixed together by this Connection Block between their end, leaves spacing 10 thereby make between their other end.Two down pressing oil cylinder 7 are installed on the front of motor of transverse arm 5, are equipped with two on the front of motor of base 9 and go up top oil cylinder 8; Described down pressing oil cylinder 7 and last top oil cylinder 8 be respectively along vertical layout of transverse arm 5 and base 9, and be end-to-end corresponding between the piston rod end of two down pressing oil cylinder 7 and two piston rod ends of going up top oil cylinders 8.When the piston rod indentation, also leave spacing between the piston rod end of the piston rod end of down pressing oil cylinder 7 and last top oil cylinder 8, so that placed in the spacing by the barrel of weldering shell ring one end.The link outside at base 9 is fixed with platform 1, and hydraulic workstation 3 and electrical control cubicles 2 are installed on the platform 1.Hydraulic workstation 3 wherein links to each other with two last top oil cylinders 8 with two down pressing oil cylinder 7 by pipeline.
Further improvement of the utility model is, on four jiaos of the lower surfaces of base 9 roller 11 is installed all, under this roller guide rail arranged.Make shell ring contra-aperture device of the present utility model to move.
When two shell rings 6 are connect welding, shell ring 6 is enclosed within the outside of transverse arm 5 and an end lower wall of this shell ring is placed between the last top oil cylinder 8 of the down pressing oil cylinder 7 of transverse arm 5 inboards and base 9 inboards, and another shell ring 6 then places between the last top oil cylinder 8 in the down pressing oil cylinder 7 in transverse arm 5 outsides and base 9 outsides lower wall of one end by movable supporting frame.When shell ring 6 because factor such as its deadweight is heavier, when the ellipticity situation appears in its interface, flexible by the piston rod of down pressing oil cylinder 7 and last top oil cylinder 8, can make the oral area alignment of two shell rings 6, to guarantee the welding quality of 6 of two shell rings.
