Description
Technical Field
The invention relates to the technical field of welding of highway construction equipment, in particular to a reinforcement cage stirrup spot welding device without welding spot omission.
Background
The reinforcement cage is a cage-shaped reinforcement framework formed by binding together reinforcement steel bars with corresponding diameters according to certain appearance requirements. The steel-concrete structure, pouring and reinforced concrete pile commonly used in modern buildings, i.e. using reinforcement cage as skeleton, filling or pouring concrete with corresponding label according to the specified process, after a certain period of maintenance, the designed bearing pressure can be reached, so as to ensure the construction requirement of its upper engineering and the future use requirement.
During the construction, often use the cage rolling machine to make the steel reinforcement cage, the cage rolling machine can drive the main muscle rotation of steel reinforcement cage and along axial displacement, at this in-process, cramp can be around establishing the surface at the main muscle to by setting up the automatic weld machine of main muscle side to weld the main muscle with around the juncture of muscle. And when in actual use, the interval of stirrup can change, so automatic weld machine can't accurate discernment main muscle and the juncture of stirrup, the condition of so appearing leaking welding or rosin joint easily, the manufacturing effect of steel reinforcement cage is poor.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a spot welding device for a reinforcement cage stirrup without welding point omission, which solves the problem that the joint of a winding reinforcement and a main reinforcement is easy to be subjected to missing welding or insufficient welding.
The purpose of the invention is realized by the following technical scheme:
the utility model provides a no steel reinforcement cage stirrup spot welding device that welding spot was omitted, includes the fuselage, be provided with the mounting panel on the top surface of fuselage, the lateral wall department of mounting panel slides and is connected with welder, welder with there is spring one between the mounting panel, spring one be used for with welder pushes away from the mounting panel supports tightly in the stirrup, welder's lateral wall department is provided with contact switch one, extrudees when the main muscle contact switch is one time, welder welds the juncture of stirrup and main muscle.
Through above-mentioned technical scheme, during the use, welder laminates in the lateral wall of stirrup all the time under the elasticity of spring one, and when the contact switch of main muscle extrusion welder lateral wall during, welder just to the juncture of stirrup and main muscle, so welder can weld the juncture of stirrup and main muscle. Make welder can conflict the lateral wall of stirrup and weld the juncture of stirrup and main muscle more than, the difficult condition that appears leaking welding or rosin joint, spot welding device's use reliability is higher.
Preferably, a distance sensor is arranged on the mounting plate and used for detecting the distance between the mounting plate and the welding gun, and therefore whether the welding gun welds the joint point of the stirrup and the main rib is judged.
Through above-mentioned technical scheme, when the distance between mounting panel and the welder is too far away, distance sensor can observe this distance and control welder and not weld the joint point of stirrup and main muscle, so be difficult for appearing between the adjacent stirrup the distance too far lead to not being conform to the condition of production demand, the staff can in time adjust the stirrup, avoid follow-up trouble of doing over again, spot welding device's use reliability further improves.
