Description

The large-scale workpiece weld holder

Technical field

The utility model belongs to the welding locating rack technical field of large-scale workpiece.

Background technology

In the prior art, the welding of large-scale workpiece need be accomplished on a large-scale positioner, and positioner is made up of support and holder, and support is made up of column, crossbeam and welding gun; Column fixes on the ground, at the center of column screw mandrel is installed, and the termination of screw mandrel is equipped with drive motors; The feed screw nut is installed on the screw mandrel, and the last crossbeam clamping plate that are equipped with of feed screw nut are when screw mandrel rotates; The feed screw nut drives the crossbeam clamping plate and moves up and down, and crossbeam is installed on the crossbeam clamping plate, on the crossbeam clamping plate, driving wheel is installed; Driving wheel promotes crossbeam and moves horizontally, and welding gun is installed in the termination of crossbeam, and crossbeam is vertical with column; Holder is made up of position, the end and workpiece locating wheel, and workpiece is placed on the workpiece locating wheel.When carrying out welding job; Because crossbeam can only move along straight line; Welding gun can only be done corresponding rectilinear motion with crossbeam; Thereby need the position while welding on the workpiece be adjusted on the straight line of welding gun process, the adjustment of workpiece position while welding need be through after the coarse adjustment of position base, and finely tuning with the workpiece locating wheel could aligned position again.In realizing operation, adjustment base and workpiece locating wheel position are very big with the work difficulty of aiming at position while welding, and the adjustment process effort is time-consuming, and operating efficiency is lower.

Summary of the invention

The utility model is for solving in the prior art, and large-scale workpiece is adjusted the position while welding work difficulty on weld holder big, and the adjustment process effort is time-consuming, and the problem that operating efficiency is lower provides a kind of large-scale workpiece weld holder, and its technical scheme is following:

The large-scale workpiece weld holder, its welding gun is installed on the support arm, and support arm is installed on the frame, and support arm is made up of welding arm and hinge arms; Hinge arms has more piece, connects with rotating shaft between the hinge arms, and welding arm is fixedly mounted on the front end of hinge arms; The welding gun mobile motor is installed on the welding arm, in the rotating shaft of welding gun mobile motor welding gun is installed and moves screw mandrel, welding gun moves and is set with the welding gun travelling nut on the screw mandrel; The welding gun travelling nut is by weldering frame bearing location, and weldering frame bearing is close on the location-plate of weldering frame, below the welding gun travelling nut; Gun rack is installed, and a welding gun is respectively installed on the both sides of gun rack, is installed with a frame feed screw nut in the rear end of hinge arms; At the middle part of frame a frame screw mandrel is installed, frame feed screw nut is sleeved on the frame screw mandrel, and bearing fixing is used at the two ends up and down of frame screw mandrel; The upper end of frame screw mandrel connects drive motors, and the rack nut fixed axis is installed on the frame feed screw nut, and the rack nut location bearing is installed in the termination of rack nut fixed axis; The rack nut location bearing stretches in the holddown groove of frame, in the side of welding arm locating rack is installed, and the below of locating rack is equipped with the electromagnet sucker;

Frame is an independently column, and the lower end fixes on the ground, and the support arm on the frame only has one.

Adopt the utility model technical scheme, during welding, large-scale workpiece is placed into the preceding appropriate location of weldering frame; Keep its weld seam level; Manual work drags hinge arms and adjusts the welding arm position of hinge arms front end, makes the path that welding gun moves on on the welding arm consistent with weld seam, starts the electromagnet sucker this moment; The fixed-site of welding arm is lived, so just can begin welding job.The welding location of above-mentioned large-scale workpiece, more faster than positioning action of the prior art, it is easier to locate, and can significantly improve the efficient of work.
