Carriage plate cylinder swing arm pressing quick positioning mechanism

Abstract

The invention discloses a carriage plate cylinder swing arm pressing quick positioning mechanism. A welding clamping cylinder is connected with a cylinder swing arm; an overturning cylinder at the bottom of the front end of the cylinder swing arm is connected to a pressing quick positioning mechanism; a rotating pin shaft is arranged on an overturning cylinder connecting base; a positioning blockis arranged at the back part of the overturning cylinder connecting base, and is connected to a positioning adjusting block; the positioning adjusting block is fixed on a tool chassis; the pressing quick positioning mechanism comprises a linear slide rail, a ball slide block and a guide rail protective cover; the linear slide rail is fixed on the tool chassis; the ball slide block is movably connected to the linear slide rail; multiple pressing rod and pressing block mechanisms and multiple positioning baffle plates are arranged at the back end of the cylinder swing arm for fixing plate coresof carriage plate parts and reinforcing ribs on the tool chassis; and presses are arranged at the top of the cylinder swing arm, and are connected with the pressing rod and pressing block mechanisms.The carriage plate cylinder swing arm pressing quick positioning mechanism greatly shortens the operation time, greatly improves the repeated positioning precision, obviously saves the labor time, andis effective and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of carriage plate welding, in particular to a rapid positioning mechanism for pressing a carriage plate cylinder swing arm. Background technique [0002] In the production and welding of light truck commercial compartment panels, there are quite a few types (the types are divided into Xinyuling 360, PT360, and light truck 360). New Yuling 360 models have 16 models with different lengths and sizes; PT360 models have 19 models with different lengths and sizes; light truck 360 models have 23 models with different lengths and sizes. The welding of different types of carriage panels is quickly and accurately positioned, installed and tightened on a set of tooling racks. Then the welding robot follows the pre-programmed program to complete the overall welding of the car panel. The carriage board includes: board core, front and rear plugs, reinforcing ribs, hinges, front and rear lock plates, and rear bolt seat. ...

AI Technical Summary

Problems solved by technology

When changing the position of the reinforcing rib on the tooling, the previous tooling was manually spot-welded on the nut, and the reinforcing rib was welded to the swing arm fixing plate and fixed on the pre-spot-welded nut with screws; this fixing method has poor accuracy (repeat positioning accuracy 2mm), replace It is troublesome to install and fix different car panels, and the pre-spot-welded nuts are not marked. It is troublesome for workers to operate and change models, wasting time
