Technical Field

The invention belongs to the technical field of clamping devices, and particularly relates to a plate clamping device for machining.

Background

Clamping is that before the workpiece starts to be machined, the workpiece must first be held in a correct position on a machine tool or in a fixture, and this process is called positioning.

Before the workpiece is machined, it must first be brought to a correct position on the machine tool or in the tool holder, a process known as positioning. In order to prevent the positioned workpiece from displacing under the action of cutting force and keep the workpiece at the correct position all the time in the machining process, the workpiece needs to be tightly pressed and clamped, and the process is called clamping. The whole process of positioning and clamping is collectively called clamping.

When the clamping is applied to machining, often still can attach the transmission of having panel, follow-up operation etc. and the subsequent operation of panel often is parted with the clamping device, the panel of different thickness is hardly adapted to on the one hand to current panel clamping device, only can fix the clamping to the panel of a single thickness, then need change anchor clamps to the panel of other thickness, it is very inconvenient, and after clamping processing is accomplished, it is convenient inadequately to the processing of panel, must artifically transport panel to other devices and carry out follow-up operation, waste time and energy.
