Abstract
The invention discloses a special jig for major-diameter thin plate disc turning. The special jig comprises a disc body, a suction air passage is arranged in the center of the disc body and is communicated with one end of a vertical suction hole, the other end of the vertical suction hole is provided with a deflated nut, the vertical suction hole is communicated with a first annular air passage on the outer end face of the disc body through a first transverse suction hole and is communicated with a second annular air passage on the outer end face of the disc body through a second transverse suction hole, and at least three bolt holes are evenly distributed around the axis of the inner end face of the disc body. The special jig has the advantages of being reasonable in design, simple in structure, reliable in performance, high in machining precision, simple in production technology, low in production cost and convenient to popularize and use, a workpiece can be mounted and dismounted conveniently, and a clamped workpiece is subjected to even force and is not prone to deformation.
Description
Technical field
The invention belongs to Machining Technology field, relate to a kind of special fixture, be specifically related to a kind of major diameter thin plate disk Special turning fixture.
Background technology
At present, for typical major diameter sheet part, such as diameter exceedes 250mm, wall thickness is less than or equal to the round plate parts of 5mm, and this type of part, in the process of turning processing, normally adopts soft pawl clamping part to carry out turning processing, during due to soft pawl clamping, produce add the power of holding and tool sharpening time the factor such as the cutting force that produces impact, this type of part easily produces distortion, thereby causes after processing part flatness and the depth of parallelism overproof, is difficult to guarantee the machining accuracy of this type of part.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of major diameter thin plate disk Special turning fixture is provided, it is reasonable in design, simple in structure, dependable performance, workpiece is easy for installation, is convenient to handling, added that to hold workpiece stressed evenly, be difficult for producing distortion, machining accuracy is high, and production technology is simple, production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: a kind of major diameter thin plate disk Special turning fixture, comprise disk body, it is characterized in that: described disk body center is provided with air-breathing air flue, described air-breathing air flue is communicated with vertical suction hole one end, the described vertical suction hole other end is provided with venting nut, described vertical suction hole is communicated with the annular air channel one that is arranged on disk body outer face by horizontal suction hole one, described vertical suction hole is communicated with the annular air channel two that is arranged on disk body outer face by horizontal suction hole two, described disk body inner face is evenly provided with at least three bolts hole around its axial location.
Above-mentioned major diameter thin plate disk Special turning fixture, is characterized in that: described disk body is disk or oval plate.
