Abstract

The invention discloses a flange positioning connecting rod assembly unit for a welding gun anti-collision device. The flange positioning connecting rod assembly unit for the welding gun anti-collision device comprises an anti-collision device body, a positioning connecting rod, a flange plate and a protective cover, wherein three radial positioning pin holes are formed in the flange plate and are evenly distributed on the circumference of a flange, three positioning pin grooves corresponding to the three positioning pin holes in the flange plate are formed in the positioning connecting rod, the included angles of radial center lines of the three positioning pin holes in the flange plate are not equal, the three positioning pin holes in the flange plate are spaced by equal angles in a rotating direction, and the included angle between the three positioning pin grooves in the positioning connecting rod correspond to the included angles between the three positioning pin holes in a one-to-one mode. According to the flange positioning connecting rod assembly unit for the welding gun anti-collision device, the relative positions of the positioning pin holes in the flange plate and the positioning pin grooves in the positioning connecting rod are reset, rapid reset can be achieved, deviation of the rotating direction during resetting is eliminated, in this way, accurate and rapid resetting is guaranteed, and production is conducted smoothly.

Description

technical field

[0001] The invention relates to the field of assembly components used on the welding torch of a manipulator, in particular to a welding torch bumper flange positioning connecting rod assembly unit. Background technique

[0002] The anti-collision sensor is an important part of the robot welding torch or welding robot, and it plays an important role in the safe use and welding accuracy of the welding torch and welding robot. The flange positioning link unit in the existing welding torch bumper plays the role of reset after collision. The flange of the existing flange is provided with three positioning pin holes in the radial direction, and the gap between the adjacent two of the three is fixed. The angle between the centerlines is 120 degrees. Corresponding to the positioning pin holes on the flange, three positioning pin grooves are also arranged on the positioning connecting rod. The locating pin is introduced into the three locating pin grooves of the loc...
