A kind of shears for bus pipe welding
technical field:
The utility model relates to a kind of shears for bus pipe welding.
background technology:
When carrying out docking welding to some pipe fittings, for convenience of the welding of automatic welding machine, lifting apparatus is often needed to be lifted by weld-end fittings.The current conventional method of lifting to pipe fitting adopts driving or bracket.But when pipe fitting diameter is comparatively large or pipe fitting is longer, the soldered pipe fitting that the above-mentioned conventional method of lifting is difficult to guarantee two adjacent keeps on the same axis.
When pipe fitting carries out docking welding, because weld seam is annular, and welding gun in automatic welding machine is once its invariant position after adjusting welding position, needs pipe fitting will do the rotation of the suitable rotating speed with welding requirements, to complete the welding of annular weld seam.Existing lifting apparatus effectively can not rotate pipe fitting, needs hand to rotate pipe fitting by roller or other tumbler works in addition, reduces operating efficiency, and dangerous.
summary of the invention:
The purpose of this utility model is that providing one can lift pipe fitting facilitates pipe fitting butt welding, conveniently can regulate again the height of soldered pipe fitting, make soldered pipe fitting be in all the time on axis height Monday a kind of for bus pipe welding shears.
For achieving the above object, shears described in the utility model comprises main support, elevating mechanism, lifting support and at least one pair of roller, described lifting support is slidably connected to main support, described elevating mechanism is placed in main support, and be connected with lifting support, drive lifting support to slide up and down on main support, two rollers in a described pair roller side by side and concentric be rotationally connected with to heavens on lifting support.
Further, described elevating mechanism comprises screw mandrel, nut, motor and Worm Wheel System unit, the rotating shaft of described motor is connected with the worm screw in Worm Wheel System unit, described nut is arranged on the worm gear wheel center in Worm Wheel System unit, screw mandrel is rotatably connected in described nut, and the upper end of screw mandrel connects described lifting support.
Conveniently be installed on maintenance, a pair roller is rotationally connected with on lifting support by rolling wheel support, and described rolling wheel support is connected to lifting support upper end, and described roller is rotatably connected on rolling wheel support.
Further, described main support is rectangular box roughly, is provided with at least one pilot hole in this casing upper surface, and described lifting support lower end is provided with the guide post suitable with described pilot hole aperture, and this guide post sliding plug is in pilot hole.
Be placed on by bus pipe to be welded and the utility model carry out butt welding when connecing, the elevating mechanism in the utility model can regulate the axis height of bus pipe, ensures that butt-welded two bus pipes are positioned at same axis height; After adjusting the height of adjacent bus pipe, in the utility model, a pair roller is used for the positioning support to bus pipe, especially when welding, because weld seam is annular, and welding gun in automatic welding machine is once its invariant position after adjusting welding position, need bus pipe will do the rotation of the suitable rotating speed with welding requirements, to complete the welding of annular weld seam, two rollers will support the bus pipe in rotation during this period.
accompanying drawing illustrates:
Fig. 1 is shears three-dimensional structure schematic diagram of the present utility model.
The B-B sectional structure schematic diagram that Fig. 2 is shears shown in Fig. 1, the lifting support of this position is in the state just starting to accept the bus pipe that roller supports.
The B-B sectional structure schematic diagram that Fig. 3 is shears shown in Fig. 1, the lifting support of this position rises to the structural representation after a certain height.
Fig. 4 is the structural representation with the bracket system of different elevating mechanism that above-mentioned B-B sectional plane is shown.
Wherein
11, main support; 12, lifting support; 13, rolling wheel support; 14, elevating mechanism; 111, pilot hole; 113, installing hole; 121, guide post; 131, roller; 141, screw mandrel; 142, nut; 143, Worm Wheel System unit; 1311,1312: roller; 1431, worm screw; 1432, worm gear; 145, tooth bar; 146, gear; 147, reducing gear.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further described.
As Fig. 1, the shears of the present embodiment has a main support 11 for rectangular box shape roughly, other parts in bracket system connect main body with this main support 11 for installing, on the downside of main support 11, rectangular shaped rim is provided with installing hole 113, to connect with the foundation bolt on corresponding installed surface, bracket system is made to be in steady status.
As Fig. 2 and Fig. 3, lifting support 12 is slidably connected on the upper surface of above-mentioned main support 11, the upper surface of main support 11 is provided with two pilot holes 111, in lifting support 12 lower end, correspondence position is provided with two guide posts 121, these two guide posts 121 respectively sliding plug, in the pilot hole 111 of correspondence, make lifting support 12 slide up and down to be connected to above-mentioned main support 11.
One rolling wheel support 13 is connected to the upper surface of lifting support 12, and this rolling wheel support 13 is a horizontally-arranged rectangle frame.Two rollers 1311,1312 in one pair roller 131 side by side and concentric height arrange, the rotating shaft of this two roller is bearing on the respective side frame of described rectangle frame by respective shaft bearing 1321.An above-mentioned pair roller 131 is for the positioning support to bus pipe, especially when welding, because weld seam is annular, and welding gun in automatic welding machine is once its invariant position after adjusting welding position, need bus pipe will do the rotation of the suitable rotating speed with welding requirements, to complete the welding of annular weld seam, two rollers 1311,1312 will support the bus pipe in rotation during this period.
