The utility model adopts the following technical scheme: a bucket deflection welding fixture comprises a base, two jacking mechanisms are arranged on the upper end surface of the base in parallel, the jacking mechanism comprises a screw rod transmission mechanism and a positioning mechanism, the screw rod transmission mechanism comprises a nut sliding plate, a screw rod and sliding rails which are arranged on two sides of the screw rod and are parallel to the screw rod, and screw rod supporting plates positioned at two ends of the screw rod, the screw rod is rotatably supported on the two screw rod supporting plates, the left section and the right section of the screw rod are divided into positive threads and negative threads, two nut sliding plates engaged with the screw rod are arranged on the left side and the right side of the screw rod through respective positive threads and reverse threads, the upper end and the lower end of each nut sliding plate are buckled on the sliding rails, one end of the screw rod penetrates through a screw rod supporting plate to be connected with the hand wheel, the positioning mechanism comprises a positioning plate which is vertically and fixedly arranged on the nut sliding plate, a supporting tip cone is fixed at the upper end of the positioning plate, and two supporting tip cones in the same positioning and tightening mechanism are coaxially arranged in a back direction. The nut sliding plate is composed of a sliding plate and a nut fixedly arranged on the back of the sliding plate, and the nut is in threaded fit with the lead screw.
The lower terminal surface of base supports and sets up a carousel, set up a plurality of and the workstation fixed connection's of machine of shifting bolt on the carousel, fix the carousel of this frock on the machine of shifting during the use, and the welding of upset and individual welding seam does not need the driving assistance, reduces the time of waiting for the driving, draws the inclined crane to the harm and the potential safety hazard of driving outward when reducing the upset.
The upper end of the positioning plate is provided with 3 tip cone mounting holes which are distributed in a triangular shape, and the small-diameter end of the supporting tip cone penetrates through one of the tip cone mounting holes to be in threaded connection with the nut on the inner side of the positioning plate. A rib plate is arranged between the positioning plate and the nut sliding plate.
When the device is used, the bucket is lifted by the travelling crane, the upper and lower hinged lug holes in the back of the bucket are coaxial with the supporting tip cone on the positioning plate respectively, then the lead screw is rotated by the hand wheel, the nut sliding plate moves outwards, the supporting tip cone and the hinged lug holes on the bucket are positioned and tightly propped, and clamping of the bucket is realized. The bucket is firm in clamping and convenient to disassemble and assemble, the welding angle of the welding line is randomly adjustable, the time is saved by more than 20 minutes compared with the time for welding the bucket lifted and turned by a travelling crane, and the working efficiency is improved by 8%.
