Background technology
Now, engineering goods become more diverse, and develop towards high accuracy, low surface roughness direction, require processing thin, planar part and superfine shaft class part.
Axial workpiece uses in mechanical industry extensively, and military project, space flight, automobile, precision optical machinery, small and special electric machine and underloading quick conveying device all have superfine shaft class part.
For the processing of major axis class, especially superfine shaft processing is one of difficult problem of mechanical processing industry.By the processing experience, usually, the draw ratio ratio of shaft diameter (axial length with) is superfine shaft more than 50.Because the superfine shaft flexibility is big, poor rigidity.During cutting, when receiving resistance to cutting, can cause bending, vibration.In addition, the radially amount of deflection that centrifugal force produced that the deadweight of superfine shaft produces, in the turning processing, the system of processing vibration takes place in the manufacturing process system that lathe-anchor clamps-cutter constituted, and these factors all influence the machining accuracy of major axis.
Traditional axle processing and loading clamp mode is a Double Tops point clamping.This installation way makes processed axle be in an extruded state, and the axle body section upwards is prone to produce flexural deformation at the diameter of axle, is arch.
The utility model content
The pin rod assembly that the technical problem that the utility model will solve provides in the extraordinary clamping technology of a kind of superfine shaft makes processed superfine shaft integral body be in " level is stretching " state, thereby obtains good expression effect, also helps assembling.
For achieving the above object, the technical scheme of the utility model is following:
Pin rod assembly in the extraordinary clamping technology of superfine shaft, it comprises screw thread pin rod and T type ring piece, said T type ring block nesting is on said screw thread pin rod; Said screw thread pin rod is made up of thread segment and polished rod section, and the external diameter M of said thread segment is slidingly matched for the H7/h6 gap between the outside diameter d 1 of said T type ring piece size files d2 and polished rod section greater than the outside diameter d 1 of said polished rod section; The size of said T type ring piece size files d 3 is less than said thread segment external diameter M.
Preferably, the length L of said screw thread pin rod thread segment is than the little 1-2mm of the processed slender axles two ends screwed hole of centre degree of depth, and it can get in the centre bore screwed hole of processed axle so that the thread segment of screw thread pin rod is screwed when installing fully.
Preferably, the size files W of said T type ring piece is 8-10mm.
Preferably, an end of said polished rod section is provided with a groove, and it helps the installation and removal of the utility model.
Preferably, said screw thread pin rod is the Cr12 material.
Preferably, said T type ring piece is a brass H62 material.
Through technique scheme, the beneficial effect of the utility model is:
The utility model pin rod assembly makes the superfine shaft of draw ratio more than 50 add man-hour integral body to be in " level is stretching " state, to help obtaining good machining accuracy like this.T type ring piece in the pin rod assembly, its size files W is 8-10mm.When T type ring piece cooperated assembling with the screw thread pin rod, size files W played the escape effect in turning.Belong to " cutter " when guaranteeing the fine finishining in the end of processed superfine shaft and be shaped, processed superfine shaft surface nothing connects the tool marks mark, does not produce the processing ripple; Precision is high; Help the surface treatment of subsequent handling: nickel plating, nitrogenize, nitrogen oxidation etc., the top layer thickness of coating is even, and coating is easy to adhere to.Obtain good apparent effect, also help assembling.
The utility model pin rod assembly, it is wide to be suitable for operation, can be used separately as the processing superfine shaft thick, in, the Seiko preface.
The utility model pin rod assembly can be widely used in mechanical manufacturing field, such as the axle type processing in: military project, space flight, automobile, precision optical machinery, small-sized and small and special electric machine and the underloading quick conveying device.
The utility model pin rod assembly integrated artistic property is good, intensity is high, is applicable in the superfine shaft technology.Can be applicable to the general category lathe, the range of work of expansion plain edition lathe promotes working ability, has changed the idea that the high precision zero parts need be used high-end devices.
The utility model pin rod assembly can make middle-size and small-size machining enterprise also can process superfine shaft, reduces unconventional major axis processing cost effectively.
