Abstract
A welding device for a main chord member and connecting pieces of a tower body standard knot comprises a base seat, a fixed end, a movable positioning device, at least two support fixed plates, and at least two steel pipe fixed racks. The fixed end and the movable positioning device are respectively positioned at two ends of the base seat. A positioning face of the fixed end is normal to an upper surface of the base seat. The support fixed plates are respectively positioned at the two ends of the base seat, and are used for positioning the connecting pieces at the two ends. The two steel pipe fixed racks are positioned between the two support fixed plates, and are used for positioning the main chord member. The movable positioning device comprises a fixed seat, an installing plate with a screwed hole, and a fixed bolt. The fixed seat is vertically fixed onto the base seat. The installing plate and the fixed seat are fixedly connected. The fixed bolt is movably connected with the fixed seat through the screwed hole on the installing plate. The welding device for the main chord member and the connecting pieces of the tower body standard knot has the advantages that: the quality of the standard knot reaching interchangeability can be guaranteed, the manufacture efficiency is improved, the material cost is reduced, and the product quality and the construction period are guaranteed.
Description
Technical field
This utility model relates to a kind of welding tooling, and particularly a kind of main chord of body of the tower standard knot and connector welding tooling belong to derrick crane manufacturing technology field.
Background technology
Very common from rising the type derrick crane in power station and construction site, but have nothing in common with each other according to the specification of using that requires, so the specification of standard knot also has nothing in common with each other.The linearity and the concentricity that in process, need to guarantee overall length, two end connections of standard knot, present way are to carry out turning processing after the welding well again, because standard knot length length causes difficulty of processing bigger, and difficult quality guarantee.And because the standard knot multi-size need be made many cover welding toolings; Since welding tooling complex structure at present commonly used and be difficult to guarantee to weld after concentricity and the linearity of standard knot require to cause the processing capacity after the welding completion excessive; Waste material, the manufacturing cost of increasing.
Summary of the invention
Goal of the invention: the purpose of the utility model provides a kind of main chord and connector welding tooling that can guarantee standard knot quality, manufacturing efficient height and can hang down the body of the tower standard knot of material cost.
Technical scheme: a kind of main chord of body of the tower standard knot and connector welding tooling; Comprise basis seat, stiff end, movable locating device, at least two support fixation plates and at least two steel pipe fixing frames; Said stiff end and movable locating device lay respectively at seat two ends, basis; The locating surface of said stiff end is vertical with the upper surface of basis seat; Said support fixation plate lays respectively at the connector that seat two ends, basis are used to locate two ends, and two steel pipe fixing frames are used to locate main chord between two support fixation plates; Said movable locating device comprises holder, installing plate and set bolt with threaded hole, and said holder vertical fixing is on the seat of basis, and installing plate is fixedly connected with holder, and set bolt passes through screwed hole and the holder flexible connection on the installing plate.Earlier a connector is placed on the support fixation plate, makes an end of connector be close to locating surface; Be placed on main chord on the steel pipe fixing frame again; On near the support fixation plate of movable locating device one end, place a connector then; Through regulating the gap between set bolt adjustment connector and the main chord; Connector and main chord entire length size are carried out symmetrical spot welding through after the assay was approved; After the spot welding firmly whole parts are put the symmetry welding of rolling on the platform.
In order to guarantee welding quality, said support fixation plate is provided with semicircle arc groove, and the diameter of said arc groove is the external diameter of connector.
In order to improve the precision of frock, said steel pipe fixing frame is provided with the V-shaped groove of 90o.
Beneficial effect: the utility model can guarantee that the quality of standard knot reaches interchangeability; Improve manufacturing efficient, reduced material cost, guaranteed product quality and duration.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
As shown in the figure; A kind of main chord of body of the tower standard knot and connector welding tooling; Comprise basis seat 1, stiff end 2, movable locating device 3, at least two support fixation plates 4 and at least two steel pipe fixing frames 5; Said stiff end 2 lays respectively at seat 1 two ends, basis with movable locating device 3; The locating surface 21 of said stiff end 2 is vertical with the upper surface of basis seat 1, and said support fixation plate 4 lays respectively at 6, two steel pipe fixing frames 5 of connector that seat 1 two ends, basis are used to locate two ends and between two support fixation plates 4, is used to locate main chord 7; Said movable locating device 3 comprises holder 31, installing plate 32 and set bolt 33 with threaded hole; Said holder 31 vertical fixing are on basis seat 1; Installing plate 32 is fixedly connected with holder 31, and set bolt 33 flexibly connects through screwed hole on the installing plate 32 and holder 31.Said support fixation plate 4 is provided with semicircle arc groove 41, and the diameter of said arc groove 41 is the external diameter of connector 6.Said steel pipe fixing frame 5 is provided with the V-shaped groove 51 of 90o.
Earlier a connector 6 is placed on the support fixation plate 4, makes an end of connector 6 be close to locating surface 21; Be placed on main chord 7 on the steel pipe fixing frame 5 again; On near the support fixation plate 4 of movable locating device 3 one ends, place a connector 6 then; Through regulating the gap between set bolt adjustment connector 6 and the main chord 7; Connector 6 and main chord 7 entire length sizes are carried out symmetrical spot welding through after the assay was approved; After the spot welding firmly whole parts are put the symmetry welding of rolling on the platform.
