Abstract

The invention relates to a stage truss connector welding fixture which comprises a rack, at least one pair of supporting blocks used for supporting the work piece, a first clamping head which can be rotated along the axial line and moved, and a second clamping head which can be rotated along the axial line, wherein, the axial lines of the first clamping head and the second clamping head are coincident, a driving shaft is fixedly connected on the second clamping head, a driven shaft is fixedly connected on the first clamping head, and a feeding mechanism which pushes the driven shaft to move along the axial direction and a driving mechanism which drives the driving shaft to rotate along the axial line are arranged on the rack. Before welding, the connectors to be welded are respectively inserted into the two ends of a beam tube, then the first clamping head and the second clamping head respectively clamp and fix the beam tube and a pair of connectors on the two sides, and drive the beam tube to rotate around the axial line. The stage truss connector welding fixture has the advantages that the clamping is convenient, the tightness is good, the rotating speed is uniform and the automaticity is high, the welding efficiency can be improved, and the welding seam is beautiful.

Description

Stage rack junction welding jig
Technical field
The present invention relates to a kind of weld jig, particularly when welding stage frame, be used for fixing the instrument of joint and pipe fitting.
Background technology
Be widely used in and set up a makeshift stage or the stage frame of exhibition position, usually weld together by three beam pipes and a plurality of diagonal angles stay pipe and form, the both ends of every beam pipe are welded with joint respectively, so as to set up a platform or during Display Rack and other pipe fittings fix, as shown in drawings.In the prior art, the welding of stage frame normally is inserted in Liang Guanzhong earlier with joint, carries out manual welding again, because manual welding needs gradation that the joint at two ends is welded, and needs side weld edge fit cant beam pipe, so its inefficiency, weld seam is inhomogeneous, influences attractive in appearance.
Summary of the invention
The purpose of this invention is to provide a kind of stage rack junction welding jig, can joint and beam pipe be fixed and rotate, conveniently weld in when welding.
The technical solution adopted in the present invention is: a kind of stage rack junction welding jig, it comprises frame, be fixedly installed at least one pair of tray that is used for supporting workpiece on the described frame, can rotate and the first mobile chuck along self axial line, second chuck that can rotate along self axial line, the axial line coincidence of described first chuck and second chuck and described first chuck and second chuck lay respectively at the both sides of described frame, be fixedly connected with driving shaft on described second chuck, be fixedly connected with driven shaft on described first chuck, also be provided with on the described frame and promote the feed mechanism that described driven shaft moves vertically and drive the driving mechanism that described driving shaft rotates along self axial line.
Described feed mechanism comprises the feeding cylinder that is fixedly installed on the described frame, and described feeding cylinder has piston rod, is connected with pedestal on the described piston rod, and described driven shaft is arranged in the described pedestal rotationally.
Described driving mechanism comprises the motor that is fixedly installed on the described frame, and described motor has rotor, and described rotor is in transmission connection mutually with described driven shaft.
Described driving mechanism also comprises shaft joint, and described rotor is in transmission connection by described shaft joint mutually with described driven shaft.
Before welding, at first joint to be welded is inserted the both ends of beam pipe respectively, again second chuck is inserted in the joint of beam Guan Yiduan, first chuck is along the axial line feeding of beam pipe and be inserted in the joint of the beam pipe other end then, utilize pin that beam pipe, joint and chuck are fixed, thereby can beam pipe and pair of joint is clamped, starter motor can make first chuck drive the beam pipe around self axial line rotation, conveniently welds.The present invention compared with prior art has convenient mounting and clamping, compactness is good, rotating speed is even, automaticity is high advantage, and it can improve welding efficiency, and weld seam is attractive in appearance.

Wherein: 1, frame; 2, tray; 3, beam pipe; 4, joint; 5, feed mechanism; 51, driven shaft; 52, pedestal; 53, feeding cylinder; 54, piston rod; 55, first chuck; 6, driving mechanism; 61, driving shaft; 62, motor; 621, rotor; 63, shaft joint; 64, second chuck; 7, carbon brush.
The specific embodiment
Referring to accompanying drawing 1 to accompanying drawing 4, a kind of stage rack junction welding jig, the axial line of first chuck 55 that it comprises frame 1, be fixedly installed at least one pair of tray 2 that is used for brace summer pipe 3 on the frame 1, can rotate and move along self axial line, second chuck, 64, the first chucks 55 that can rotate along self axial line and second chuck 64 overlaps and first chuck 55 and second chuck 64 lay respectively at the both sides of frame 1.
Be fixedly connected with driving shaft 61 on second chuck 64, be fixedly connected with driven shaft 51 on first chuck 55, also be provided with on the frame 1 and drive the driving mechanism 6 that driving shaft 61 rotates along self axial line, driving mechanism 6 comprises: be fixedly installed on motor 62 and shaft joint 7 on the frame 1, motor 62 has rotor 621, and rotor 621 is in transmission connection by shaft joint 7 mutually with driven shaft 61.
Also be provided with on the frame 1 and promote the feed mechanism 5 that driven shaft 51 moves vertically.Feed mechanism 5 comprises: be fixedly installed on the feeding cylinder 53 on the frame 1, feeding cylinder 53 has piston rod 54, is connected with pedestal 52 on the piston rod 54, and driven shaft 51 is arranged in the pedestal 52 rotationally.
Before the welding, at first pair of joint to be welded 4 is inserted in the two ends of beam pipe 3 respectively, again second chuck 64 is inserted in the joint 4 of a side wherein, and beam pipe 3 is placed on the tray 2, by control feeding cylinder 53, make 55 feedings of first chuck and be inserted in the joint 4 of beam pipe 3 opposite sides, thereby beam pipe 3 and pair of joint 4 are clamped, and, make beam pipe, joint and chuck phase spline with in the pin-and-hole on pin insertion beam pipe 3 and two joints 4; Starter motor 62 makes driving shaft 61 drive beam pipes 3 around self axial line uniform rotation, operating personnel can the sidepiece of frame 1 or above weld.
In the present embodiment, feed mechanism 5 adopts air cylinder driven, and manually all right or other mode feedings treat that workpiece is fixed by a locking device after clamped again.Because second chuck is by motor-driven, be to prevent that the loop current between welding gun and the workpiece from wounding motor when arc welding, can a sheathed carbon brush 7 on the driving shaft 61, loop current is drawn by carbon brush 7, sees accompanying drawing 1; In addition, shaft joint should be selected the shaft joint that has insulating properties concurrently for use.
