At present, for typical major diameter sheet part, such as diameter is more than 250mm, wall thickness is less than or equal to the round plate parts of 5mm, and this type of part, in the process of turnery processing, normally adopts soft pawl holding parts to carry out turnery processing, due to the impact of the factors such as the cutting force that produces when the blessing power that produces during soft pawl clamping and tool sharpening, this type of part easily produces distortion, thus after causing processing part flatness and the depth of parallelism overproof, be difficult to ensure the machining accuracy of this type of part.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of large-scale sheet work pieces process pneumatic suction formula fixture is provided, its workpiece uniform force, can not distortion be produced, effectively improve workpiece processing quality and production efficiency, reasonable in design, structure is simple, work-handling is easy, and production technology is simple, is convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: a kind of large-scale sheet work pieces process pneumatic suction formula fixture, comprise disk body, it is characterized in that: also comprise and be arranged on described disk body outer face for the annular air channel one that adsorbs sheet workpiece and annular air channel two, for the air intake passage that is communicated with vavuum pump air entry and the bolt hole for fixedly mounting described disk body; Described disk body center is provided with described air intake passage, described air intake passage is communicated with the vertical suction hole one end being arranged on described disk body inside, be positioned at the described vertical suction hole other end outside described disk body and be provided with venting nut, described vertical suction hole is communicated with described annular air channel one by horizontal suction hole one, described vertical suction hole is communicated with described annular air channel two by horizontal suction hole two, and described disk body inner face is evenly provided with at least three described bolts hole around its axial location.
Above-mentioned large-scale sheet work pieces process pneumatic suction formula fixture, is characterized in that: described disk body is disk or oval plate.
Above-mentioned large-scale sheet work pieces process pneumatic suction formula fixture, is characterized in that: be provided with gasket seal between described air-breathing air flue and described sheet workpiece.
Above-mentioned large-scale sheet work pieces process pneumatic suction formula fixture, is characterized in that: be provided with gasket seal between described annular air channel one and described sheet workpiece.
Above-mentioned large-scale sheet work pieces process pneumatic suction formula fixture, is characterized in that: be provided with gasket seal between described annular air channel two and described sheet workpiece.
The utility model compared with prior art has the following advantages:
(1) when this large-scale sheet work pieces process is with pneumatic suction formula fixture clamping sheet workpiece, adopt vacuum suction sheet workpiece, thus by blessing sheet workpiece uniform force, not easily produce distortion, and it effectively improves crudy and the production efficiency of sheet workpiece.
(2) this large-scale sheet work pieces process is very reasonable by pneumatic suction formula jig Design, and sheet workpiece only need be placed on disk body lateral surface by operating personnel, starts the clamping operation that vavuum pump can complete sheet workpiece, very easy to use.
(3) this large-scale sheet work pieces process pneumatic suction formula fixture operation is easy, and sheet workpiece is convenient to installation and removal.
(4) this large-scale sheet work pieces process is simple by pneumatic suction formula fixture production technology, and production cost is low, is convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.
