Problems solved by technology
At present, the traditional general automatic welding tongs have many disadvantages, such as large installation space, far distance between the welding point and the clamping point, and the wear of the electrode under the welding tongs cannot be compensated, etc.
These shortcomings make the solder joints on the surface of the parts distorted, which seriously affects the welding quality

Embodiment Construction
[0036] Such as Figure 1 to Figure 9 As shown, a welding gun 100 according to an embodiment of the present invention includes: a power element 102 that provides driving power, a driving mechanism 20 connected to the power element 102 and driven by the power element 102, and connected to the driving mechanism 20 and driven by the driving mechanism 20 The first electrode mounting seat 24 for driving action, and the electrode mounted on the first electrode mounting seat 24 and driven by the first electrode mounting seat 24 to perform the closing operation or realize the open state, are connected to the driving mechanism 20 and are driven by the driving mechanism 20 The chuck mounting seat 26 for driving action is installed on the chuck mounting seat 26 and driven by the chuck mounting seat 26 to close, clamp and fix the workpiece to be processed or loosen the chuck 40 to realize the opening action. In this embodiment, the first electrode mounting seat 24 and the chuck mounting seat...

Disclosed are welding tongs (100) comprising a power element (102), a drive mechanism (20) connected to the power element, an electrode mounting seat (24) actuated by the drive of the drive mechanism, an electrode (30) mounted on the electrode mounting seat and driven by the electrode mounting seat to close or achieve an open state, a clamp mounting seat (26) arranged to correspond to the electrode mounting seat and connected to the drive mechanism and actuated by the drive thereof, and a clamp (40) mounted on the clamp mounting seat and driven to close or open by the clamp mounting seat. By correspondingly arranging both an electrode mounting seat and a clamp mounting seat on the drive mechanism, the electrode and the clamp are correspondingly arranged on the same welding tongs and form an integral structure, the welding tongs can perform integral drive and control via the power element, solving the problems of conventional welding tongs being relatively remote from the clamp clamping the workpiece, and the mounting and positioning, etc. being inconvenient for control and manipulation because the two are arranged separately. In addition, control and automated manipulation are facilitated by the drive mechanism performing integrated driving to enable integrated control.
Description
Technical field [0001] The invention relates to a welding equipment, in particular to a welding clamp. Background technique [0002] Most automobile manufacturers at home and abroad use resistance spot welding for body welding. The manual welding method is low cost but the welding quality is unstable, while the robot welding unit is used, which requires a large investment, high production cost and high maintenance cost. In order to reduce production costs without affecting welding quality, many manufacturers have begun to research and adopt simplified automatic welding equipment. At present, the traditional general automatic welding gun has many disadvantages, such as a large installation space, a long distance between the welding point and the clamping point, and the wear of the lower electrode of the welding gun cannot be compensated. These shortcomings cause the distortion of the solder joints on the surface of the part, which seriously affects the welding quality. Summary ...
