Preferably, described base is vertically installed with multiple vertical panel, each described vertical panel is provided with fixture described at least one.
Preferably, described fixture comprises the Horizontal clamp on fixing described workpiece level limit and the vertical clamp of fixing described workpiece vertical edges, described Horizontal clamp and vertical clamp include cylinder and fixture block, described cylinder comprises cylinder block and cylinder arm, and described fixture block is fixedly installed on the cylinder arm of described cylinder.
Preferably, described fixture also comprises the fixed block be arranged on described vertical panel, and the cylinder arm of described fixture is all just to described fixed block, and described workpiece limit is clamped between the two by described fixture block and fixed block.
Preferably, described base has also been horizontally disposed with several base cylinders, the cylinder arm of each described cylinder is just to described vertical panel.
Preferably, vertical panel described at least one is also provided with the side plate of horizontal-extending, described side plate is provided with described Horizontal clamp.
Preferably, described workpiece is rectangular structure, and it comprises the long limit of level, minor face and vertical column; Described base is provided with six described vertical panels, is respectively: the first vertical panel, the second vertical panel, the 3rd vertical panel, the 4th vertical panel, the 5th vertical panel and the straight plate of sextuple; Wherein, described first vertical panel and the second vertical panel are arranged on the outside on the described long limit of workpiece one, described first vertical panel and the second vertical panel are arranged on the inner side on another long limit of described workpiece, described 5th vertical panel is arranged on the outside of described workpiece one minor face, and the straight plate of described sextuple is arranged on the inner side of described another minor face of workpiece.
Preferably, described 3rd vertical panel, the 4th vertical panel, the 5th vertical panel and the straight plate of sextuple are provided with described side plate, the straight plate of described sextuple arranges Horizontal clamp described in, and the fixed block of this Horizontal clamp is arranged between the cylinder block of this Horizontal clamp and fixture block.
Preferably, described vertical panel is removably disposed on described base by bolt.
Frame structure workpiece welding bench of the present invention by gripping the every bar limit forming workpiece, thus is shaped preferably, is convenient to welding.In whole process, do not rely on the experience of operative employee, shape of product is stable, quality is high, and does not need the later stage to adjust, and production efficiency is high.In addition, also by the meticulous setting of the position of fixture, the taking-up after making it not hinder formed product.Frame structure workpiece welding bench of the present invention has the advantages such as structure is simple, efficiency is high, good product quality.

Detailed description of the invention
Below the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, a kind of frame structure workpiece welding bench of the present invention comprises base 10.Base 10 is vertically provided with multiple vertical panel (level vertically and hereinafter is herein all with under the normal duty of welding bench, is that being vertically parallel to ground is level perpendicular to ground, lower same).Base 10 and vertical panel are all provided with fixture, whole fixture actings in conjunction, every for workpiece 12 bar limit is all fixed, to weld.Fixture can adopt the device of any current existing held circular pipe or square tube, such as, be with flexible clip etc.What adopt in preferred embodiment is cylinder, arranges a fixture block 36 before the cylinder arm of each cylinder, and fixture block 36 is under the driving of cylinder and the fixed block 34 be arranged on vertical panel or directly and the clamping formed between vertical panel workpiece 12.The clip vertical of holding workpiece 12 horizontal sides is arranged, and is called vertical clamp 32; The fixture of holding workpiece 12 vertical edges is horizontally disposed with, and is called Horizontal clamp 30.Above structure, can realize the fixation of the workpiece 12 to any shape, is convenient to welding.After also needing now to solve workpiece 12 welding fabrication, the problem how to take off from fixture.Can adopt the scheme that common, namely vertical panel is removably disposed on base 10 by bolt 14, thus is realized workpiece 12 taken off by dismounting vertical panel.But efficiency is lower.
For this reason, invention has been further improvement.To weld the workpiece 12 of a cuboid tower structure, in preferred embodiment, have employed 6 vertical panels, vertical panel is arranged along the rectangular edge of workpiece 12 bottom surface, comprising: the first vertical panel 16, second vertical panel 18, the 3rd vertical panel 20, the 4th vertical panel 22, the 5th vertical panel 24 and the straight plate 26 of sextuple.Wherein, the first vertical panel 16 and the second vertical panel 18 are arranged on the outside on the long limit of workpiece 12 1, and the 3rd vertical panel 20 and the 4th vertical panel 22 are arranged on the inner side on another long limit of workpiece 12; 5th vertical panel 24 is arranged on the outside of workpiece 12 1 minor face, and the straight plate 26 of sextuple is arranged on the inner side of another minor face of workpiece 12.3rd vertical panel 20, the 4th vertical panel 22, the 5th vertical panel 24 and the straight plate 26 of sextuple are provided with side plate 28, side plate 28 are provided with Horizontal clamp 30.Wherein, the operation principle of the Horizontal clamp 30 on the straight plate of sextuple 26 is slightly different with other Horizontal clamp 30, its fixed block (not shown) is arranged between the cylinder block of this Horizontal clamp 30 and fixture block 36, forms chucking power and fix workpiece 12 when namely it is reclaimed by fixture block 36 and between fixed block 34.And other fixture is when utilizing fixture block 36 outwards mobile, and forms chucking power between fixed block 34 and fix workpiece 12.
Adopt above structure, when vertical panel need not be dismantled, can take off the workpiece 12 welded.Its operation principle is: first unclamp each fixture, is then first moved to sextuple straight plate 26 direction by workpiece 12, then moves to the first vertical panel 16 direction, finally move up, can take out workpiece 12.
Above embodiment is only the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
