Abstract
The present invention discloses a device without welding horse and an assembly method for steel box girders. The device without welding horse for steel box girders is characterized in that a master form (2) is fixedly connected with a portal frame (1) which has a supporting wheel (7) on the bottom lateral part; the shape of the bottom of the master form (2) is corresponding to the shape of a fitting (3); a work piece (5) is placed on an installing platform (8); the assembly lines of the fitting (3) and the work piece (5) are on the contraposition; the portal frame (1) is moved to the end of the fitting (3), and then is positioned to be processed with assembly welding. Since a 'mechanical horse' is used for assembly welding instead of the 'welding horse', the present invention can improve assembling efficiency, improve the external appearance and the inner quality of the fitting, and save a great amount of labor and materials.
Description
(1). technical field
The invention belongs to metal processing structure assembling field, the mechanical positioning fixture of particularly a kind of usefulness replaces the device and the assembly method of positioning fixture for welding.
(2). background technology
In the steel construction manufacture field, often need the assembly welding that assembles with the various accessories of processing structure.In this process, adopt the positioning fixture for welding method of (in welding field, being called " welding horse ") usually, accessory is positioned welding assembly, and welding assembly all need be located with " positioning fixture for welding " in the location, everywhere.After assembling finishes, need " welding horse " cut out, consume more " welding horse " steel and welding rod.Accessory need be used grinder buffing with the crator that " welding horse " contact position stays, and consumes great amount of manpower.Owing to when accessory being assembled the location welding, produce bigger internal stress, cause member to organize latent defect and outside easy-to-rust simultaneously at weld.And when cutting out " welding horse ", make the accessory surface cause defectives such as undercut, arc crater, burn easily, cause the fatigue damage of member.
(3). summary of the invention
Purpose of the present invention provides the method that the mechanical positioning fixture of a kind of usefulness replaces the device of positioning fixture for welding and uses this device assembling accessory.It replaces " welding horse " with mechanical positioning fixture, and assembly method is simple, does not consume " welding horse " steel, significantly reduces member because internal stress and the fatigue damage that welding produces.
The invention is characterized in that for reaching above-mentioned purpose described anchor clamps are made up of door frame, pattern, support wheel (pin) and platform, support wheel on the door frame (pin) is supported on the side of platform, pattern is fixedlyed connected with the door frame that bottom side has support wheel (pin), and the shape of pattern bottom is corresponding with the shape of accessory.
The bottom of door frame also is provided with travelling wheel.Gapped between pattern and the accessory.
The assembly method that replaces the device of positioning fixture for welding with mechanical positioning fixture, be that workpiece is placed on the mounting platform, the assembly line contraposition of accessory and workpiece moves to the end of accessory with door frame, is inserted in the gap between pattern and accessory tiltedly to carve so that accessory and workpiece location.
The present invention is owing to replace " welding horse " assembly welding that assembles with the various accessories of processing structure with mechanical positioning fixture, therefore when assembly welding, do not consume " welding horse " steel and welding rod, there is not crator that accessory and " welding horse " contact position stay etc., accessory does not have to have improved the outward appearance and the inherent quality of accessory owing to its internal stress that causes and fatigue damage.Adopt portable " mechanical horse " that accessory is assembled assembly welding, can assemble assembly welding to a plurality of accessories simultaneously, increase substantially efficiency of assembling, save great amount of manpower and material.
The present invention is described further below in conjunction with accompanying drawing.
(4). description of drawings
Fig. 1 is the structure diagram of a kind of embodiment of the present invention;
Fig. 2 is the enlarged drawing of B portion among Fig. 1;
Fig. 3 is the another kind of embodiment of apparatus of the present invention assembling;
Fig. 4 is another embodiment of apparatus of the present invention assembling.
(5). the specific embodiment
Fig. 1 is the installation diagram that the present invention is used for steel case beam slab unit.Pattern 2 is fixed on the top of door frame 1.Drawing assembly line on the platform 8, the workpiece 5 of delimiting bit line is placed on the assembly line, accessory 3 is placed in workpiece 5 scribing position, the door frame 1 of taking away wheel 6 is moved to the end of accessory 3, because the shape of pattern 2 bottoms is corresponding with the shape of accessory 3, and leaves the gap between pattern 2 and accessory 3.Referring to Fig. 2.Be embedded in the gap of pattern 2 and accessory 3 accessory 3 and workpiece 5 are positioned adjustment with tiltedly carving 4, support wheel on the door frame 1 (pin) 7 is supported on the side of platform, make door frame 1, pattern 2, support wheel (pin) 7 form " mechanical horse ", form continuous assembly welding assembly line with platform.
After a spots localization assembly welding that utilizes door frame 1,2 pairs of accessories 3 of pattern and workpiece 5 is finished, mobile door frame 1 usefulness is tiltedly carved 4 and is embedded in the gap of pattern 2 and accessory 3, accessory 3 and workpiece 5 are positioned adjustment, support wheel on the door frame 1 (pin) 7 is supported on the side of platform, make door frame 1, pattern 2, support wheel (pin) 7 form " mechanical horse ", second position positioned assembly welding with platform.So come and go, finish up to whole accessory 3 and workpiece 5 assemblings.
The displacement of door frame 1 is decided with the alignment situation of workpiece 5 according to the distance and the accessory 3 of location assembly welding.
Fig. 3 is the installation diagram that the present invention is used for H shaped steel.1 pair of H shaped steel of door frame forms continuous assembly welding assembly line, and makes the shape of pattern 2 bottoms corresponding with the shape of accessory 3.With aforesaid method H shaped steel is positioned assembly welding.
Fig. 4 is the installation diagram that the present invention is used for big specification solder sphere band steel peculiar to vessel.1 pair of big specification solder sphere band steel peculiar to vessel of door frame forms continuous assembly welding assembly line, and makes the shape of pattern 2 bottoms corresponding with the shape of accessory 3.With aforesaid method big specification solder sphere band steel peculiar to vessel is positioned assembly welding.
The invention is not restricted to above-mentioned example.The mechanical positioning fixture of all usefulness replaces " welding horse " batch assembling to steel construction location assembly welding, all should belong to scope of the present invention.
