TECHNICAL FIELD

[0001] The present application relates to the technical field of welding, in particular to a welding tongs connected with a gripper mechanism. BACKGROUND

[0002] At present, when the conventional production line welding robot is welding, a transfer robot needs to be used for transfer, but often due to the influence and limitation of the site, it is impossible to install a gripper robot for part transfer, and a person needs to be transferred, which increases the labor intensity of personnel and reduces the processing efficiency; at present, when the welding robot is equipped with a transfer device, a gripper is generally arranged beside the welding gun, that is, the welding gun and the gripper use the same base, the welding gun and the gripper work respectively, and the two cannot be separated, so the overall size is large, and if the overall flow line space is expanded, the gripper still needs to be moved, which increases the energy consumption of the equipment. For example, the published patent 2022220334842 discloses a welding gun and gripper integrated mechanism, a servo motor and a servo welding tongs connected with the output end of the servo motor are arranged on the welding gun, the welding gun is arranged on a support, and at least one gripper assembly is arranged on the side of the support away from the welding gun. The integrated structure can simultaneously realize the functions of welding and transfer, and does not need to additionally use a separate robot for gripping and transferring. However, there is still the problem that the overall size is large, and if the overall flow line space is expanded, the gripper still needs to be moved, which increases the energy consumption of the equipment. Therefore, it is particularly important to solve the problem that the welding gun with the gripper mechanism cannot be detached and the overall size is too large. SUMMARY

[0003] The purpose of the present application is to provide a welding tongs connected with a gripper mechanism, which can be externally connected to the welding tongs body through the connecting flange when the gripper function is needed, and only needs to be detached when not needed, without suspending the gripper mechanism for welding, thereby improving the working efficiency, increasing the adaptability, and solving the problem that the welding gun with the gripper mechanism cannot be detached and the overall size is too large.

[0004] The present application provides a welding tongs connected with a gripper mechanism, which comprises a welding tongs body, a fixed welding tongs and a movable welding tongs are arranged at the front of the welding tongs body, the fixed welding tongs is in a C shape, and the welding head of the fixed welding tongs is arranged opposite to the welding head of the movable welding tongs, the movable welding tongs is arranged on the welding tongs body, and a movable cylinder is arranged at the rear end of the movable welding tongs, the movable welding tongs is driven to move by the extension rod of the movable cylinder, a connecting flange is arranged on the side of the welding tongs body, and the connecting flange is used for externally connecting the gripper mechanism, the gripper mechanism is connected with the welding tongs through the connecting flange, so that the welding tongs is provided with the gripper mechanism.

[0005] Further improvement lies in that a cooling pipeline is arranged on the fixed welding tongs, and the welding tongs is cooled through the cooling pipeline.

[0006] Further improvement lies in that the waterway pipe orifice is arranged on the welding tongs body, the waterway pipe orifice is one in and one out, is connected with the cooling pipeline, and is used for passing cooling water into the cooling pipeline.

[0007] Further improvement lies in that the side of the moving air cylinder is provided with a guard plate, and the guard plate is installed on the side of the moving air cylinder through bolts.

[0008] Further improvement lies in that the connecting flange is provided with an insulating positioning pin, and the installation position of the gripper mechanism is limited through the insulating positioning pin.

[0009] Further improvement lies in that the welding tongs body side is further provided with a metal porous cable waterproof joint, and the cable is connected through the metal porous cable waterproof joint.

[0010] The present application has the beneficial effects that when the gripper function is needed, the gripper mechanism is externally connected to the welding tongs body through the connecting flange, when not needed, only the gripper mechanism needs to be disassembled, without suspending the gripper mechanism for welding, the working efficiency is improved, the adaptability is increased, the welding tongs are cooled through the cooling pipeline, the service life of the welding equipment is increased, the installation position of the gripper mechanism is limited through the insulating positioning pin, the precision of the gripper mechanism is improved, different sizes of gripper mechanisms can be additionally installed, and different gripping requirements can be adapted.
