Description

Technical Field

[0001] This utility model relates to the field of mechanical device technology, and in particular to a parallel pressing and anti-deformation mechanism. Background Technology

[0002] Automotive arc welding is an important welding technology in automobile manufacturing. It uses an electric arc as a heat source and is suitable for welding thick metal sheets.

[0003] Currently, in automotive arc welding, due to the long and numerous weld seams, a large amount of heat is generated, which can lead to part deformation. Therefore, it is essential to propose a parallel clamping anti-deformation mechanism to avoid low product qualification rate caused by large product deformation during the arc welding process. Utility Model Content

[0004] The purpose of this invention is to provide a parallel pressing anti-deformation mechanism, which aims to avoid large deformation of products during the arc welding process, thereby improving the product qualification rate.

[0005] To achieve the above objectives, this utility model employs a parallel pressing and anti-deformation mechanism, comprising a driving unit, a connector, a first hinge plate, a second hinge plate, a third hinge plate, a placement unit, and a limiting block. The connector is connected to the driving unit, the first hinge plate is rotatably connected to the connector, one end of the second hinge plate is rotatably connected to the connector, one end of the third hinge plate is rotatably connected to the second hinge plate and located at the end of the second hinge plate away from the connector, and the placement unit is fixedly connected to the third hinge plate and located at the end of the third hinge plate away from the second hinge plate.

[0006] The drive unit includes a cylinder mounting plate and a cylinder, the cylinder being fixedly connected to the cylinder mounting plate, and the connector being fixedly connected to the output end of the cylinder.

[0007] The placement unit includes a slide rail mounting plate and a slide rail. The slide rail mounting plate is fixedly connected to the third hinge plate. The slide rail is located below the slide rail mounting plate, and the slide rail mounting plate is slidably connected to the slide rail.

[0008] The placement unit further includes a shim, which is provided on one side of the slide rail.

[0009] The parallel pressing and anti-deformation mechanism further includes a limiting block, which is disposed above the joint.

[0010] This utility model discloses a parallel pressing and anti-deformation mechanism. During arc welding, a workpiece is placed on the placement unit, and the driving unit is driven to operate. The driving unit drives the joint, the first hinge plate, the second hinge plate, and the third hinge plate to move. Finally, the first hinge plate, the second hinge plate, and the third hinge plate are aligned in a straight line. At the same time, the third hinge plate pushes the placement unit to move forward in parallel, forming a three-point straight-line dead point structure. This effectively ensures that the deformation force of the workpiece cannot cause the mechanism to retreat, avoiding large deformation of the product during the arc welding process, thereby improving the product qualification rate.

[0027] Furthermore, the parallel pressing and anti-deformation mechanism also includes a limiting block 70, which is disposed above the joint 20.

[0028] In this embodiment, the limiting block 70 is disposed above the joint 20 and presses the first hinge plate 30 and the second hinge plate 40 to limit the first hinge plate 30 and the second hinge plate 40.
