Background
In the machining process, in order to enable the surface of the workpiece to meet the technical requirements of size, geometric shape, mutual position precision with other surfaces and the like specified by a drawing, the workpiece needs to be positioned and clamped before machining. The machine tool clamp is used for positioning and clamping a workpiece. The machine tool clamp is divided into a universal clamp and a special clamp, and the special clamp is generally adopted for special-shaped parts, thin-wall parts and parts with special processing requirements. The special machine tool fixture is usually composed of a positioning element for determining the correct position of a workpiece in the fixture, a clamping device for clamping or pressing, a tool setting guide element for determining the relative position of a tool and the workpiece or guiding the direction of the tool, an indexing device for machining the workpiece at a plurality of stations in one-time installation, a connecting element, a fixture body and the like.

The surface and the hole that inside and outside need process are more, because of need carry out metal cutting to the work piece, required clamp force is big, and the requirement is pressed from both sides tightly reliably simultaneously, and work is steady, convenient to use. The traditional machining center clamp adopts the pressing plate bolt to clamp the part, so that the production efficiency is low, the operation is complex, the labor intensity of workers is greatly increased, meanwhile, the clamp is not suitable for special-shaped parts, and the qualification rate of the part is not stable; in addition, a special positioning and clamping device needs to be designed aiming at special structural characteristics on parts, and high design requirements are provided for how to ensure accurate positioning and stable clamping and processing without deformation aiming at special-shaped thin-shell parts. At present, hydraulic clamps are widely used in the production process, namely, hydraulic elements are used for replacing mechanical parts for positioning and clamping. Vibration and deformation in machining are reduced through the floating support, and the clamping position is kept away in the machining by automatically controlling the pressing and lifting of the pressing plate. The hydraulic clamp can bear large cutting force during rough machining, can ensure accurate positioning during precise machining, and can also complete support, clamping and quick release which cannot be completed by a manual clamp. Because the shape of the part is complex and the size is smaller, the time required for single-piece processing is less than the auxiliary time, and the single-piece processing has poor economy,
As six surfaces and holes on the surfaces of the part need to be processed and have higher geometric tolerance requirements, the clamp needs to be capable of overturning, so that a device capable of rotating within a range of 360 degrees is arranged, and the purpose of clamping and processing a plurality of parts at one time is very necessary.
