Modular flexible vacuum clamp for numerical control machine tool and clamping method of modular flexible vacuum clamp

Abstract

The invention discloses a modular flexible vacuum clamp for a numerical control machine tool and a clamping method of the modular flexible vacuum clamp. The modular flexible vacuum clamp comprises a clamp mainboard 1 and a vacuum module 2; and the clamp mainboard has universality, and is mainly used for effectively and quickly positioning, connecting and tightly clamping the vacuum module, and meanwhile outputting a main body of a vacuum air source and realizing the connecting and tightly clamping of a whole tool and a machine tool worktable. The vacuum module is a main component for clampingand positioning a part. The modular flexible vacuum clamp is simple in process, low in manufacturing cost, convenient to operate, high in flexibility, high universality, low in maintaining cost, and capable of being popularized and applied to the numerical control machine tool.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a modular flexible vacuum clamp for a numerically controlled machine tool and a clamping method thereof. Background technique [0002] A large number of aeronautical structural parts generally require vacuum fixtures in CNC machining. Due to the different shapes and structures of parts, a set of special vacuum fixtures must be customized for each part. All existing vacuum fixtures are integral. That is to say, the tooling base plate and the vacuum positioning area are integrated. From the perspective of manufacturing, it increases the difficulty of manufacturing tooling and increases the manufacturing cycle of tooling; from the perspective of users, it prolongs the development and processing cycle of parts and increases the cost of tooling. In addition, once the vacuum fixture fails or is damaged, it is difficult to repair and restore, and most of them...

Problems solved by technology

In the past, the method of straightening and aligning vacuum tooling is generally to use the dial indicator installed on the machine tool spindle to straighten and align the tooling after placing the tooling on the machine tool. The process is complicated, time-consuming, laborious, and error-prone.

Aircraft parts are generally complex in structure, high in material cost, and large in tooling, which determines the high requirement for one-time pass rate of CNC machining to avoid unqualified parts. However, the production preparation work before CNC machining is often complicated and time-consuming, which affects the delivery cycle of parts.
