Abstract

The invention relates to a special clamping device for double-sided pressing of plate workpieces, which includes a base plate, a support frame, a cylinder, a turntable, a connecting rod and a pressure plate. A support frame is installed on one side of the upper surface of the base plate. The back plate and the top plate are composed of a workpiece installation area on the top surface of the top plate, a vertical positioning column is installed on the rear end of the top plate surface, and a horizontal top wire is installed on the front surface of the top plate; a hinge is installed on the other side of the bottom plate surface A cylinder is installed on the hinge seat, and the cylinder is connected with an active push rod. The upper ends of the two connecting rods are hinged with a pressing plate, and the two pressing plates are respectively located above the left and right sides of the top plate. The invention is a special clamping device for double-sided pressing of plate workpieces with a high degree of automation. Using the device can increase the clamping speed, ensure the processing quality, improve the product qualification rate, and save the raw material and labor costs of the enterprise.

Description

technical field

[0001] The invention relates to a clamping fixture in the technical field of machining, in particular to a special clamping device for double-sided pressing of a plate workpiece. Background technique

[0002] Plate workpieces are widely used in electronic instruments or other industries, and the surface of many plate parts needs to be milled and drilled, such as heat sinks. At present, when processing it, it is usually pressed manually with a pressure plate. Since the force applied by the staff is not easy to control, especially many workpieces are made of aluminum, when the force is too large, it is easy to scratch the surface of the workpiece and affect its use. If the applied force is too small, the clamping will not be stable, which will affect the effect of milling and drilling. In addition, because the plate workpiece needs to be pressed on both sides at the same time, the pressing force on both sides cannot be guaranteed to be exactly the same during ...
