Description

TECHNICAL FIELD

[0003] However, the conventional laser cladding operation process cannot operate on various types of workpieces, so that a new operation environment and equipment need to be replaced every time the workpiece is replaced, and the production efficiency is reduced. Therefore, a new workbench needs to be designed to solve the above problems. UTILITY MODEL CONTENT

[0008] Further, the clamping surface of the clamping jaw is in a stepped type. The stepped clamping jaw ensures uniform distribution of the clamping force through a larger contact surface, thereby reducing workpiece deformation; and the clamping jaw can clamp the inner circle, the outer circle and the bar of the workpiece, and has high flexibility and versatility.

[0009] Further, the ejector pin mechanism comprises an ejector pin base and an ejector pin; the ejector pin base is arranged on the placement table; and the ejector pin is arranged on the ejector pin base and located on one side close to the rotating clamping mechanism.

[0010] Further, the rotating frame can rotate 90 degrees with the upper plate, drives the clamping direction of the clamping jaw to change from the longitudinal direction to the transverse direction, and the clamping jaw cooperates with the ejector pin to complete the transverse clamping.

[0011] Further, the moving mechanism comprises left-right moving linear modules, front-rear moving linear modules and up-down moving linear modules; the left-right moving linear modules, the front-rear moving linear modules and the up-down moving linear modules are sequentially stacked and connected.
