Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing equipment, in particular to a stamping pick-and-place fixture. Background Art

[0002] A wide variety of auto parts are used in automotive manufacturing, many of which are manufactured through stamping. For example, automotive floors, spoilers, front and rear fenders, and heat sinks can all be manufactured using stamping. The stamping process for auto parts generally involves the following steps: First, the appropriate metal material is selected based on the part's drawings and requirements. Then, the sheet metal is stamped and formed using processing equipment such as a punch press. However, existing semi-automatic stamping processes for auto parts still rely heavily on manual placement and placement, which can be labor-intensive and prone to misalignment. Among them, the existing patent document with publication number: CN219561175U discloses a stamping pick-and-place fixture for automotive parts, which mounts the workpiece on a mounting plate and uses multiple clamps to clamp and fix the workpiece, so that the workpiece is fixed more firmly and stably, avoiding processing deviation. During the stamping process, there is no need for workers to touch it, which greatly improves the personal safety of workers. After the workpiece is stamped, the rotary motor drives the workpiece to rotate again, so that the workpiece rotates to the other side, which is convenient for workers to pick up materials. When picking up materials, the second telescopic rod drives the push plate to move, and the push plate drives the push plate to move through the connecting rod, so that the workpiece can be pushed to assist in unloading, making it more convenient for workers to pick up materials.

[0003] When the above-mentioned pick-and-place fixture is actually used, the workpiece is clamped by the relative movement of the three clamping plates, and then rotated and extended by the drive of multiple motors to drive the workpiece to move; because the three clamping plates are used to clamp thinner and longer sheet materials, the workpiece is easily attached to the mold after stamping, resulting in the three clamping plates being unable to clamp the edge of the workpiece, and it is also easy to cause deformation of the sheet material, reducing applicability and efficiency.
