Abstract
The utility model provides a telescopic welding device applicable to the longitudinal seam welding of a square box which is large in slenderness ratio and small in cross section. The telescopic welding device mainly comprises a telescopic internal support mechanism and a long joint compressing mechanism. The telescopic internal support mechanism takes a core shaft as again support shaft, takes an air cylinder as a power component, and transfers the force by an external support rod, an inclined wedge, a bearing, an aluminum strip support frame and the like, so that a box plate of the square box can be independently supported from four directions. The long joint compressing mechanism adopts a piano keyboard type compressing mechanism, and an air bag is taken as a power component to control the lifting up and down of a piano keyboard so as to control whether a workpiece is compressed or not... As the core shaft in the telescopic internal support mechanism is better in strength and rigidity, and the compacting force of the piano keyboard is adjustable and controllable, so that the welding deformation can be effectively controlled.

The utility model content
The purpose of the utility model has provided a kind of welder that is applicable to that big L/D ratio small bore square chest welding longitudinal seam welding is used, and has solved the long straight weld automation welding of asymmetric square inner chamber demand.Concrete technical scheme is following:
Welder mainly comprises telescopic interior support mechanism and slit hold-down mechanism two parts, and two parts are used inside and outside the casing chamber.
As shown in Figure 1, telescopic interior support mechanism mainly comprises six parts such as mandrel, outer strut, carriage, weld seam cushion block, supporting seat and cylinder.With mandrel is main back shaft, and mandrel is fixed, and supporting seat is fixed on the mandrel four direction along mandrel respectively; Carriage is fixed in the supporting seat and can be free to slide; The weld seam cushion block is fixed on the carriage, and the weld seam cushion block mainly contacts with welding work pieces, plays the support fixation welding work pieces.Voussoir is fixed on the outer strut, and outer strut can be free to slide in the supporting seat bearing.Adopt cylinder as dynamical element, through power transmissions such as outer strut, wedge, bearing, aluminum strip carriage, interior support mechanism four direction independent support square chest boxboard.On every mandrel four angles be supported for independent outer support structure, be convenient to regulate control, guarantee putting in place of size because inner cavity size is limited, the structural design of this interior support form is more compact.Simultaneously, be minimizing weight, proof strength, mandrel adopts the honeycomb fashion beam structure, and adds auxiliary support frame.
Hold-down mechanism is as shown in Figure 2, and the slit hold-down mechanism mainly comprises key, key pad, spring leaf, five parts such as fixed axis, air bag.Key is fixed in two keys together through fixed axis.Spring leaf plays the key of upspringing automatically below key.Adopt air bag as dynamical element, compress both sides key compressing structure through airbag aeration.Compress air pressure and divide precompressed and formally compress two grades, every grade of compaction pressure is adjustable.Because weld seam is longer, air bag is divided into three sections in the slit hold-down mechanism, and each section air bag acts on separately, and key divides three sections controls on the fusion length direction like this, is convenient to the adjustment in gap.
This device can guarantee interior accurately the putting in place of supporting of casing, and the location steel bar has higher linearity and flatness in the long scope of 3m; Key adopts the air bag mode to compress the thrust uniformity that key has guaranteed whole keys, has effectively guaranteed the uniformity of dispelling the heat in the welding process to help improving the appearance of weld uniformity; Because mandrel has strength and stiffness preferably in the scalable interior support mechanism, and the adjustable control of key thrust, effectively controls welding deformation.The application of this invention achievement can be applicable to the automation welding of many inner box structures part and produces, and also uses demonstration for the robot welding production of various complex thin-wall structures provides many plates automation welding assembling to provide.
This device has excellent adaptability to the long longitudinal joint automation welding of the thick different materials square chest of 1-5mm assembling, can adapt to the welding of different welding methods (TIG arc welding, MIG arc welding, Laser Welding etc.).

The specific embodiment
Through instance the utility model is done further explanation below; But it should be noted that; The purpose of publicizing and implementing example is to help further to understand the utility model; But it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and appended claim, various replacements and to revise all be possible.Therefore, the utility model should not be limited to the disclosed content of embodiment, and the utility model requires the scope of protection to be as the criterion with the scope that claims define.
Specific embodiment
A kind ofly be applicable to that the longitudinal seam welding of big L/D ratio small bore square chest is with scalable welding actual device.This device comprises that the longitudinal seam welding of four big L/D ratio small bore square chests uses scalable welder, each scalable welder mainly comprise telescopic in support mechanism and slit hold-down mechanism two parts.Support mechanism is main back shaft with mandrel in telescopic, adopts cylinder as dynamical element, through power transmissions such as outer strut, wedge, bearing, aluminum strip carriage, four direction independent support square chest boxboard.The slit hold-down mechanism adopts the piano type hold-down mechanism, utilizes air bag depressing and lifting and control workpiece and whether compress as dynamical element control key.
Support mechanism mainly comprises six parts such as mandrel, outer strut, carriage, weld seam cushion block, supporting seat and cylinder in telescopic.With mandrel is main back shaft, and mandrel is fixed, and supporting seat is fixed on the mandrel four direction along mandrel respectively; Carriage is fixed in the supporting seat and can be free to slide; The weld seam cushion block is fixed on the carriage, and the weld seam cushion block mainly contacts with welding work pieces, plays the support fixation welding work pieces.Voussoir is fixed on the outer strut, and outer strut can be free to slide in the supporting seat bearing.Adopt cylinder as dynamical element, through power transmissions such as outer strut, wedge, bearing, aluminum strip carriage, interior support mechanism four direction independent support square chest boxboard.On every mandrel four angles be supported for independent outer support structure, be convenient to regulate control, guarantee putting in place of size because inner cavity size is limited, the structural design of this interior support form is more compact.Simultaneously, for reducing weight, proof strength adopts the honeycomb fashion beam structure, and adds auxiliary support frame.
