Abstract
The invention discloses a thin-wall round pipe turning fixture. The thin-wall round pipe turning fixture comprises a step mandrel, and further comprises multiple disc springs and a pressing plate for pressing the disc springs, wherein a workpiece positioning table and a disc spring cushion table are arranged at one end of the step mandrel in sequence; an external thread is arranged at the other end of the step mandrel; the step mandrel is coated by multiple disc springs for outwards ejecting and supporting thin-wall round pipes to be machined; elastic rubber sleeves for increasing the frictional force between the disc springs and the thin-wall round pipes to be machined are arranged at the outer sides of the disc springs; the pressing plate for applying the axial pretightening force to the disc springs is arranged on the step mandrel at one sides of the disc springs; and a pressing nut fitting the external thread for use is arranged on the step mandrel at one side of the pressing plate. The thin-wall round pipe turning fixture has the characteristics of reasonable design, simple structure, high machining precision, convenience for workpiece disassembly, low labor intensity, high production efficiency, long service life, low production cost and convenience for promotion and application.
Description
Technical field
The invention belongs to Machining Technology field, relate to a kind of fixture, being specifically related to a kind of compressing fixture for cutting thin-wall circular tube.
Background technology
Due to thin-wall circular tube have that wall is thin, poor rigidity and the feature such as intensity is weak, so be easy to occur the situations such as stress deformation, temperature distortion and vibration deformation in its process.Thin-wall circular tube is when carrying out turnery processing, need to use scroll chuck on lathe spindle to clamp, but because the wall of thin-wall circular tube is thin, poor rigidity and intensity weak, very easily distortion is produced under the effect of scroll chuck clamping force, thus have impact on the required precision of its dimensional accuracy and form and position tolerance, simultaneously because thin-wall circular tube is thinner, the heat in metal cutting produced in Tutrning Process can cause the thermal deformation of thin-wall circular tube, makes the size of thin-wall circular tube more be difficult to ensure and control.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, provide a kind of thin-wall circular tube turning clamp, it is reasonable in design, and structure is simple, machining accuracy is high, workpiece easy accessibility, and labour intensity is low, and production efficiency is high, fixture long service life, 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 thin-wall circular tube turning clamp, comprises ladder axle, it is characterized in that: also comprise multiple butterfly spring and the pressing plate for compressing described butterfly spring, described ladder axle one end is disposed with Workpiece fixing platform and butterfly spring pad, the described ladder axle other end is provided with external screw thread, described ladder axle is set with multiple for outwards holding out against and supporting the butterfly spring of described thin-wall circular tube to be processed, described butterfly spring arranged outside has the elastic caoutchouc cover for increasing frictional force between described butterfly spring and described thin-wall circular tube to be processed, described ladder axle is positioned at described butterfly spring side and is provided with the pressing plate applying axial pre tightening force to described butterfly spring, described ladder axle is positioned at described pressing plate side be provided with described external screw thread with the use of clamp nut.
Above-mentioned thin-wall circular tube turning clamp, is characterized in that: be provided with packing ring between described pressing plate and described clamp nut.
Above-mentioned thin-wall circular tube turning clamp, is characterized in that: described packing ring is open washer.
The present invention compared with prior art has the following advantages:
(1) design of this thin-wall circular tube turning clamp is very reasonable, and simple and compact for structure, multiple butterfly spring is with the use of effectively holding out against thin-wall circular tube from inside, and thus its clamping effect is good, and machining accuracy is able to effective guarantee.
(2) this thin-wall circular tube turning clamp workpiece easy accessibility, operating personnel only need use spanner to rotate clamp nut can compress or unclamp thin-wall circular tube to be processed, and thus labor strength is low, and production efficiency is high.
(3) in use there is not rigid shock in this thin-wall circular tube turning clamp, thus its long service life.
(4) a lot of parts of this thin-wall circular tube turning clamp are convenient to produce, buy all very much, and thus its production cost is very low, is convenient to batch production, promotes the use of.
Below by drawings and Examples, the present invention is described in further detail.
