Embodiment 1

[0042] Refer to the attached Image 6 Shown: a flexible positioning method for a welding torch for a robot, which includes the following steps:

[0043] 1) Before the welding torch 7 works, on the welding torch positioning unit 3, the welding torch female head of the welding torch 7 is positioned and locked by the welding torch positioning pin 32, the welding torch support unit 6 supports the welding torch 7 to ensure balance, and the dust cover 4 is closed to protect welding torch 7;

[0044] 2) when the welding torch 7 is working, the robot drives the gun-changing disc male head of the welding torch 7 to move toward the robot with the welding torch flexible positioning device, and the rotary cylinder 5 rotates and drives the dust cover 4 to rotate, and the dust cover 4 is opened;

[0045] 3) The robot drives the male head of the torch changer of the welding gun 7 to insert it into the female head of the welding gun 7. The position sensor 34 detects that the male head of the...

Abstract

The welding gun flexible positioning device for the robot is characterized by comprising a trapezoid support, a cross beam support, a welding gun positioning unit, a dustproof cover, a rotating air cylinder, a welding gun supporting unit, a welding gun female head for locking a welding gun through a welding gun positioning pin, a position sensor for detecting the connection relation between a gun replacing disc male head of the welding gun and a gun replacing disc of the welding gun female head, and a position sensor for detecting the position of the welding gun female head. Positioning is simple and reliable, and operability is high; the positioning method comprises the steps that the two welding guns are both hung on the welding gun flexible positioning device, the robot drives the gun replacing disc male head to move to the position near the device, the robot drives the gun replacing disc male head to be inserted into the female head on the welding gun, welding gun positioning locking and site specifications are relieved, and the 6s site quality management regulation is met.

Description

technical field [0001] The invention relates to a station appliance, in particular to a flexible positioning device and a positioning method for a welding torch for a robot. Background technique [0002] In the welding workshop, the body-in-white production line is produced in the form of workstations. The same workstation has multiple functions such as resistance spot welding, gluing, and testing. Each robot is equipped with at least two welding torches. In order to adapt to the highly flexible production of the production line, In the production of modern automobile industry, there are more and more intelligent production. The welding production line adopts the form of multiple workstations to meet the needs of various types of car bodies. The existing technology includes the following welding gun management methods for the welding production line. [0003] In Patent Document 1 (CN21218178), a teaching tool for a gun-changing tray stop station is disclosed, which includes ...
