Abstract
The invention discloses an external thread turning fixture of a thin-wall sleeve. The fixture comprises a step thread shaft, an elastic expansion sleeve and a taper sleeve, wherein a positioning table is arranged at one end of the step thread shaft; an outer conical surface is arranged on the step thread shaft at one side of the positioning table; the step thread shaft is coated by the elastic expansion sleeve; the taper sleeve is arranged between the elastic expansion sleeve and the step thread shaft; inner conical surfaces having the same taper with the taper sleeve are respectively arranged at the inner sides of the two ends of the elastic expansion sleeve; multiple rubber strips for increasing the frictional force between the elastic expansion sleeve and a workpiece to be machined are arranged at the outer side of the elastic expansion sleeve through mounting grooves; and a pressing nut for tightly pressing the taper sleeve is arranged on the step thread shaft. The 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 turning clamping, be specifically related to a kind of for the externally threaded fixture of turning thin-wall sleeve.
Background technology
Due to thin walled cylinder body 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 walled cylinder body is when turning external screw thread, need to use scroll chuck on lathe spindle to clamp, but because the wall of thin walled cylinder body 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 walled cylinder body is thinner, the heat in metal cutting produced in Tutrning Process can cause the thermal deformation of thin walled cylinder body, makes the size of thin walled cylinder body 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 walled cylinder body external threading fixture, 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 walled cylinder body external threading fixture, comprises ladder thread spindle, it is characterized in that: also comprise elastic expansion-sleeve and coning sleeve, described ladder thread spindle one end is provided with the positioning table for locating workpiece to be processed, described ladder thread spindle is positioned at described positioning table side and is provided with the male cone (strobilus masculinus) with described coning sleeve with identical tapering, described ladder thread spindle is set with for outwards holding out against and supporting the elastic expansion-sleeve of described workpiece to be processed, coning sleeve is provided with between described elastic expansion-sleeve and described ladder thread spindle, the inner conical surface with described coning sleeve with identical tapering is provided with inside described elastic expansion-sleeve two ends, many the rubber strips for increasing frictional force between described elastic expansion-sleeve and described workpiece to be processed are provided with by installing groove outside described elastic expansion-sleeve, described ladder thread spindle is provided with the clamp nut for compressing described coning sleeve.
Above-mentioned thin walled cylinder body external threading fixture, is characterized in that: be provided with open washer between described clamp nut and described coning sleeve.
Above-mentioned thin walled cylinder body external threading fixture, is characterized in that: the range of taper of described coning sleeve is: 30 °-60 °.
The present invention compared with prior art has the following advantages:
(1) this thin walled cylinder body external threading jig Design is very reasonable, simple and compact for structure, elastic expansion-sleeve and coning sleeve with the use of, clamping effect is good, and machining accuracy is high.
(2) this thin walled cylinder body external threading clamp workpiece easy accessibility, operating personnel only need use spanner to rotate clamp nut and can compress or unclamp workpiece 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 walled cylinder body external threading fixture, thus its long service life.
(4) a lot of parts of this thin walled cylinder body external threading fixture 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.
