Abstract

The invention relates to a stage truss welding bench which comprises a rack, a pair of fixing seats arranged on the two sides of the rack, a pair of fixture blocks which can be both rotated and moved and a feeding cylinder, wherein, the rotating axial lines of the fixture blocks are coincident, each fixture block is provided with three claws, and the projection of the connecting lines among the three claws on the vertical plane is triangular; the feeding cylinder is provided with a first piston rod, the fixture blocks are rotatablely arranged on the first piston rod, and the axial line of the first piston rod is coincident with the rotating axial lines of the fixture blocks. Before processing, ends of three transverse tubes are respectively inserted on the claws on one fixture blocks, the cylinder is controlled so that the fixture blocks on the two sides clamp and fix the transverse tubes, and then welding can be carried out. In the welding process, the fixture blocks can be rotated manually, and the welding of three sides of the transverse tubes can be completed in sequence. Compared with the prior art, the stage truss welding bench has the advantages that the clamping is convenient, the positioning is accurate, and the welding efficiency and the qualified rate of the products can be improved.

Description

Welding bench of stage rack

Technical field

The present invention relates to a kind of welding bench of stage rack, is the instrument that is used for fixing transverse tube when welding stage frame.

Background technology

Be widely used in and set up a makeshift stage or the stage frame 3 of exhibition position, weld together by three transverse tubes 31 and many reinforced pipes 32 usually and form, shown in accompanying drawing 3 and accompanying drawing 4.Utilize prior art welding stage frame, normally in advance with three transverse tube spot welding, its relative position is fixed, and then many reinforced pipes are welded on respectively on three sides of stage frame, position between when welding three transverse tubes relation is difficult to determine like this, therefore locate inaccuracy between each beam pipe, be easy to generate waste product, efficient is also lower.

Summary of the invention

But the purpose of this invention is to provide a kind of quick-clamping and the fixing welding bench of stage rack of transverse tube.

The technical solution adopted in the present invention is: a kind of welding bench of stage rack, it comprises frame, relatively is arranged on a pair of holder of described frame two opposite sides portion, be provided with not only rotatable on described each holder but also fixture block and drive the feeding cylinder of described fixture block movably along its axial line feeding, the rotational axis line of described a pair of fixture block overlaps, and have three claws on described each fixture block, the projection of line on vertical guide between described three claws is triangular in shape; Have the first piston bar on the described feeding cylinder, described fixture block is arranged on the described first piston bar rotationally, and the axial line of described first piston bar overlaps with the rotational axis line of described fixture block.

Also have the slide rail that extends along vertical on described each holder, be slidingly connected with slide on the described slide rail, described feeding cylinder is fixedly installed on the described slide, and described fixture block is arranged on the described slide rotationally.

The top of described each holder also is set with the lift cylinders that drives described slide block lifting, has second piston rod on the described lift cylinders, and described slide is fixedly connected on the end of described second piston rod.

Before processing, respectively an end of three transverse tubes is inserted on the claw on the fixture block, drive the feeding cylinder fixture block of both sides is fixedly clamped transverse tube, can weld, but hand-turning fixture block in the process of welding is finished the welding of three sides of transverse tube successively.The present invention compared with prior art has the advantage of convenient mounting and clamping, accurate positioning, can improve welding efficiency and product percent of pass.

The specific embodiment

Referring to accompanying drawing 1 and accompanying drawing 2, a kind of welding bench of stage rack, it comprises frame 1, relatively is arranged on a pair of holder 2 of frame 1 two opposite sides portion.Be provided with not only rotatable on each holder 2 but also fixture block 21 and promote the feeding cylinder 23 that fixture block 21 moves along its rotational axis line movably.The rotational axis line of a pair of fixture block 21 overlaps, and the projection of line on vertical guide that has on each fixture block 21 between 211, three claws 211 of three claws is triangular in shape; Have first piston bar 231 on the feeding cylinder 23, fixture block 21 is arranged on the first piston bar 231 rotationally, and the axial line of first piston bar 231 overlaps with the rotational axis line of fixture block 21.

One end of three transverse tubes 31 is inserted respectively on the claw 211 of one of them fixture block 21, the two ends of transverse tube 31 all offer pin-and-hole 33, and also have the hole on the claw 211, when the feeding cylinder 23 of both sides drives first piston bar 231 along fixture block 21 feedings, just transverse tube 31 is clamped, use pin 4 again, make transverse tube 31 and claw 211 fixing in transverse tube 31 and the claw 211, when rotating fixture block 21, transverse tube 31 can correspondingly rotate.

Also has the slide rail 25 that extends along vertical on each holder 2, be slidingly connected with slide 26 on the slide rail 25, feeding cylinder 23 is fixedly installed on the slide 26, and fixture block 21 is arranged on the slide 26 rotationally, this slide 26 is driven by the lift cylinders 24 that is fixedly installed on holder 2 tops, have second piston rod 241 on the lift cylinders 24, slide 26 is fixedly connected on the end of second piston rod 241.During welding, operating personnel weld in a side of frame 1, wait to weld after the one side, need the upset workpiece, weld other side, and control lift cylinders 24 this moment, and it is promoted slide 26, have so just made things convenient for the revolving stage frame.

Wherein, feeding cylinder and lift cylinders can be cylinder or oil cylinder.
