Abstract
The invention discloses a clamp special for thin plate part milling. The clamp comprises a base and further comprises a sealing plate, wherein a step cavity is formed inside the sealing plate. Two parallel supporting plates are fixedly installed on the upper side of the base. The sealing plate is fixedly installed at the upper ends of the two supporting plates. An air outlet and an air inlet are communicated with a lower cavity body of the step cavity and are formed in the lower portion of the side wall of the sealing plate. The air outlet is communicated with a vacuum opening of a vacuum pump. A positioning element is arranged in an upper cavity body of the step cavity of the sealing plate. A sealing element for preventing gas leakage is arranged between the positioning element and the sealing plate. A plurality of vertical gas passageways are evenly formed in the positioning element and communicated with the lower cavity body of the step cavity. The clamp has the advantages of being reasonable in design, simple in structure, convenient to operate, capable of evenly exerting force on workpieces, not prone to deformation, capable of effectively improving workpiece machining quality and production efficiency, simple in manufacturing process, low in production cost and convenient to popularize and use.
