Description

Column crane mast section main chord welder
Technical field:
The present invention is the welding of column crane mast section main chord, relates to utilizing positioner to weld, utilize source of the gas location clamping, the material returned and technical process.
Background technology:
The at present welding of column crane mast section main chord, each part of main chord all is behind artificial positioning welding on the frock, workpiece is unloaded frock freely to be welded or freely welds to the robot positioner, processed the most afterwards two end faces of main chord, it mainly is to consider to weld in frock, and welding deformation is large, and workpiece unloads difficulty, two end faces processing at last main chord solve the end face unevenness that free welding deformation brings, the utilization of this method lost labor and equipment.
Summary of the invention:
In order to overcome above-mentioned deficiency, the purpose of this invention is to provide a kind of column crane mast section main chord welder.
To achieve these goals, the present invention adopts following technical scheme:
Column crane mast section main chord welder, it comprises drive end, the revolution location, square tube compresses cylinder, guide plate, V-block and rotatably compress cylinder, tower machine main chord of standard section square tube, the positioner frame, robot, material returned cylinder, supported end, tiltedly carve push-and-pull cylinder base seat, tiltedly carve the push-and-pull cylinder, mobile installing plate, tiltedly carve the push-and-pull cylinder jointing, boosting lever, boosting lever hinge seat, tiltedly carve, spring steel wire, tower machine main chord of standard section adapter sleeve, the adapter sleeve coarse positioning, adapter sleeve compresses keeper, adapter sleeve compresses cylinder, stifle, connect the trepanning keeper, adapter sleeve end face keeper, mounting plate, tower machine main chord of standard section square tube is held on and does circumferentially location on the V-block of part, compressing cylinder by square tube drives mobile installing plate and relies on guide plate to compress tower machine main chord of standard section square tube, rely on mobile installing plate, after square tube location-plate on the mounting plate was done end face location, the cylinder that rotatably compresses that starts V-block and rotatably compress cylinder compressed.Be installed on tiltedly to carve and tiltedly carve the push-and-pull cylinder by tiltedly carving being connected of push-and-pull cylinder jointing and boosting lever on the push-and-pull cylinder base seat, rotate boosting lever around the bearing pin that is installed on the boosting lever hinge seat, promote tiltedly to carve, and rely on the spring steel wire that is installed between stifle and connection trepanning keeper, so that tiltedly carve and the inclined-plane close contact that is connected trepanning keeper and adapter sleeve end face keeper.Tower machine main chord of standard section adapter sleeve is held on the adapter sleeve coarse positioning, and is enclosed within on the connection trepanning keeper, compresses cylinder by adapter sleeve and drives adapter sleeve compression keeper, and top adapter sleeve end face keeper is to the clamping of tower machine main chord of standard section adapter sleeve location.By the drive end place and servomotor robot communication, and rely on supported end, drive the positioner frame and turn to suitable position, to positioner frame location, robot is according to the programming automatic welding by the revolution location.Tiltedly carve push-and-pull cylinder-pushed boosting lever, pulling is tiltedly carved, and the spring steel wire resilience is by the material returned cylinder workpiece of backing off.
The present invention has the following advantages:
1. change processing technology
Change two end faces of traditional postwelding processing main chord, after first each part of main chord being machined, weld at positioner, can reduce like this radius of gyration of part processing, improve the utilization of equipment, save simultaneously tack welding assembly unit frock and artificial.
2. solve and unload the workpiece difficult problem
On the inclined-plane that utilizes welding stress to be applied to tiltedly to carve, the push-pull effort that reduces tiltedly to carve, in actual use, the coefficient of friction of two parts of inclined-plane contact is not a fixed number, but certain scope is arranged, strengthen the push-pull effort of tiltedly carving with boosting lever, ensure that the coefficient of friction of two parts of inclined-plane contact can change within the specific limits, thereby can utilize the less push-pull effort of cylinder just can unload smoothly workpiece.
