[0001] This utility model relates to the technical field of calipers, and in particular to the technical field of heavy machinery calipers. Background Technology
[0002] On automated production lines, workpieces are typically positioned and clamped by mechanical calipers. Existing robotic arm caliper structures, as shown in patent document CN205075059U, clamp the workpiece using two parallel clamping bodies.

The caliper body includes an integrally formed main board, a cross jaw, and a connecting plate. The cross jaw and the connecting plate are located on the same side of the main board. The cross jaw is located at the bottom of the main board, and the connecting plate is located above the cross jaw. A trapezoidal groove is provided between the cross jaw and the connecting plate. The top of the cross jaw is horizontal, and a vertical through hole is provided on the connecting plate.
[0005] Preferably, the bottom of the cross claw is provided with a bevel, which slopes downward along the direction of the motherboard.
[0006] Preferably, the surface of the motherboard is provided with several grooves, and the edges of the grooves are provided with reinforcing ribs.
