Riveting and welding tool for the beam on the inner gantry of forklift trucks

Abstract

The invention discloses rivet welding tool equipment used for upper beams of inner masts of forklifts. The rivet welding equipment comprises a base, a pneumatic tightening mechanism and a positioning mechanism, wherein a rotation body support is arranged on the base, and a round hole is formed in the top plate of the rotation body support; the pneumatic tightening mechanism comprises an air cylinder, a control valve for controlling the air cylinder and a guide rod; the guide rod is vertically arranged and is linked with the piston of the air cylinder; a rotation body sleeves the guide rod; the positioning mechanism comprises a panel, a pair of supports and a pair of spindle nose positioners; the panel is fixedly connected with the rotation body; the two supports are symmetrically arranged on the two ends of the middle part of one side of the panel; the two spindle nose positioners are symmetrically arranged on the two ends of the top part of one side of the panel; each support is a horizontal-type strip-shaped vertical plate; a pair of baffle plates is arranged on the panel above the two supports; each spindle nose positioner comprises a support plate, a pressing plate, a screw rod, a screw barrel and an adjusting baffle block; each support plate is connected with the panel; each pressing plate is connected with the corresponding support plate through a pin shaft; each support plate and the corresponding pressing plate are spliced to form a round bayonet, and are locked and positioned through the corresponding screw rod and the corresponding screw barrel; and therefore, the integrity of the station of workpiece assembly and the station of welding is realized.

Description

technical field [0001] The invention belongs to the field of welding tooling, in particular to a riveting welding tool for the upper beam of the inner mast of a forklift. Background technique [0002] At present, the welding of the upper beam of the inner mast of the forklift needs to go through two processes of upper beam assembly and upper beam welding; the existing process method is to first assemble the upper beam on the welding tool, and then manually move the assembled upper beam After the robot is welded, it is manually transported to the logistics platform and flowed into the gantry welding station. [0003] The existing method of welding the inner mast of a forklift has the following disadvantages: (1) During the entire assembly and welding process of the inner mast, the transportation is completely realized by people, and the entire transportation process needs to be manually carried many times, and the production efficiency is low; ( 2) The labor intensity of per...
