Description

Processing machine composite clamping device

The invention mainly discloses a clamping device, in particular a composite clamping device of a processing machine.

Before the machining machine processes the work, the work must be clamped and fixed by the vise to ensure that the work does not move during the machining process, but the traditional vise has fixed clamps and movable clamps, and the work is placed on the fixed clamp. Between the movable forceps and the movable forceps, until the work object contacts the fixed clamp and the movable clamp at the same time, the work object is subjected to the clamping force from the fixed clamp and the movable clamp to generate friction, thereby achieving the effect of fixing the work.

However, the fixing effect that can only be achieved by the friction of the vise is not good. When the cutting force of the processing machine is too large, the workpiece may still be slipped and displaced, resulting in processing failure, damage to the processing machine, and even occurrence. Dangerous, if the clamping force is increased to increase the friction, it is easy to cause uneven deformation of the workpiece.

In view of the above-described deficiencies of the prior art, the inventors have devised a composite clamping device for a processing machine that overcomes all of the disadvantages of the prior art described above.
