Description

Technical Field

[0001] This utility model relates to the field of electric welding positioning technology, and in particular to an anti-deformation electric welding positioning fixture. Background Technology

[0002] Welding fixtures are specialized equipment that use mechanical structures to constrain welding workpieces. Their core function is to achieve precise positioning and stable clamping of the workpiece during the welding process, thereby effectively controlling welding deformation. Depending on the industrial application scenario, welding fixtures can be divided into pipe welding fixtures, automotive parts fixtures, sheet metal anti-warping fixtures, etc. Modern welding fixtures generally adopt modular design.

[0003] Existing welding positioning fixtures mainly utilize three core modules: clamping components, transmission mechanisms, and positioning devices. They employ technologies such as gear and toothed plate meshing and hydraulic drive to precisely control the clamping force, facilitating the welding process. However, due to varying product structures, manually operated positioning fixtures can easily exert forces on products during welding, leading to deformation under the combined action of the welding gun and the fixture. Therefore, this invention proposes an anti-deformation welding positioning fixture to address these problems in the existing technology. Utility Model Content

The electric rotating seat, rotating rod, rectangular plate, and arc-shaped clamp provide a close-fitting clamping action according to the product's structure. Since the fixed clamping mechanism is symmetrical about the rotation center axis of the mounting plate, the force on the product can be balanced, thus effectively preventing product deformation.

The electric rotating seat 204 then outputs power, causing the rectangular plate 206 or arc-shaped clamp 207 at one end of the rotating rod 205 to position and clamp the product. When a movable clamping position is required, the second bolt... After the arm base 302 on the bolt base 301 is in operation, the power robotic arm 303 and the electric rotating rod 304 are hinged and adjusted so that the lower gripper 305 or the upper gripper 306 can clamp the product in a movable position.
