Embodiment 1

[0019] Such as figure 1 with figure 2As shown in Fig. 1, a robot gripper repair welding positioning tool, the arm of the robot is provided with a robot gripper 16, the frame of the robot gripper is in the shape of "mesh", welded by rods made of square tubes, the robot gripper There are three positioning holes on it. The repair welding positioning tool for the robot grasping parts includes a base plate 1, which is embedded in the ground, and three vertical fixture columns 2 are connected to the base plate 1 through flanges, and the three fixture columns 2 are arranged in an L shape. The top of each fixture column 2 is provided with a bending part 9 bent downward, and the bending part 9 is provided with a robot gripper positioning fixture, and the robot gripper positioning fixture includes a gripper positioning mechanism and a gripper locking mechanism. Described robot gripper location fixture also comprises a column connecting plate 6 and clamp mounting plate 7, is prov...

Embodiment 2

[0022] There are two fixture columns 2, the direction of the parallel slots on the column connecting plate 6 is the vertical direction, the direction of the parallel slots on the fixture mounting plate 7 is the horizontal direction, and there are two positioning pins 15 and two locking hooks 3. When the gripper positioning fixture positions the robot gripper, the positioning pins 15 are separated on both sides of the robot gripper frame, such as image 3 shown. All the other are with embodiment 1.

Abstract

The invention discloses a positioning fixture for repairing welding of a workpiece gripped by a robot. An arm of the robot is provided with a robot gripping tool; the positioning fixture for repairing welding of the workpiece gripped by the robot comprises a substrate, wherein the substrate is provided with a fixture column; the fixture column is provided with a robot gripping tool positioning fixture matched with the robot gripping tool; the robot gripping tool positioning fixture comprises a gripping tool positioning mechanism and a gripping tool locking mechanism. By the fixture, the robot gripping tool can be positioned and locked by the robot gripping tool positioning fixture in the air, more support is obtained, external force from a welding device during welding can be better borne, the positions of the robot gripping tool and the workpiece are stably kept, and the welding quality is better ensured.

Description

technical field [0001] The invention relates to an automobile body assembly tool, more specifically, it relates to a robot gripper repair welding positioning tool. Background technique [0002] At present, in the automotive industry, robots have been widely used, especially on welding lines. On the existing automatic welding line, due to space constraints and cost considerations, the car body to be welded is usually fixed and clamped with a small number of shuttle fixtures and the positioning welding is completed, and then the workpiece that has completed the positioning welding is moved from Pick it up from the shuttle fixture and lift it into the air, other welding equipment gathers towards the workpiece, perform repair welding in the air to complete the welding of the remaining parts, while performing repair welding, the shuttle fixture can shuttle from the positioning welding station back to the loading station, Carry out the loading and fixing of the next workpiece, so...
