The chuck is used as a clamping mode commonly used in etching equipment. According to different power sources, the method is divided into: three jaw chucks, air chucks, and the like.

The three-jaw chuck is adopted: the chuck is manually operated to clamp and unclamp the workpiece by using the chuck key so as to clamp the workpiece. When the marking operation of the automobile brake disc is carried out, after the workpiece is placed, the chuck is locked by the aid of the manual chuck key, and when the marking is finished and the workpiece is disassembled, the chuck is opened by the aid of the manual chuck key under high force. This operation is repeated continuously during the production process. When the production changing operation is performed, the chuck is manually adjusted to a proper clamping radius by using the chuck key, so that the production can be performed. When the workpiece is marked by the clamping mode, the chuck is locked and released repeatedly by manpower, so that time and labor are wasted, the labor intensity is high, and the positioning and marking efficiency is low.

By adopting the air chuck, the piston in the cylinder is driven to move by compressed air to clamp and unclamp the chuck, so that the workpiece is clamped. The marking is started, after the workpiece is placed, the gas circulation is controlled through the electromagnetic valve, the chuck is locked, when the workpiece is disassembled after the marking is finished, the gas is controlled through the electromagnetic valve to stop, the chuck is loosened, and the circulation is repeated during line production.

The pneumatic chuck is used for clamping the workpiece, a pneumatic system consisting of a corresponding pressure air source, a pneumatic element and a pipeline is needed, and the structure is relatively complex. The conventional air chuck has the effective stroke of about 27mm and the clamping range is limited. When the marking operation is not carried out on the brake discs with different radius sizes, the clamping radius of the chuck is manually adjusted, the operation process is complex, and the production efficiency is low; particularly, when the multi-variety small-batch production is carried out, the influence of the production changing operation on the production efficiency is particularly remarkable.
