Abstract

The invention discloses a finish machining device and a machining method of a conical seat surface of a ferrule tube fitting. The machining device comprises rollers in contact with a ferrule conical seat surface and a rotatable main shaft capable of axially advancing. The main shaft is provided with a ring support, the ring support is provided with the rollers, and various rollers are symmetrically and evenly arranged around the main shaft, and central axes of the rollers are in the same conical surface. The machining method comprises the following steps: rough machining the conical seat surface of the tube fitting, then fixing a workpiece with the main shaft and advancing the main shaft of the finish machining device along the axial direction of the conical seat surface; allowing the workpiece to rotate relative to the main shaft after the rollers are joint on the conical seat surface; and rolling and finish machining the conical seat surface of the tube fitting by the rollers. Compared with the prior art, the machining device has simple structure, short machining time, simple operation and identical angular dimensions, reduces roughness of the machined conical surface from Ra6.3-3.2 to 0.8-0.1, greatly improves precision and hardness of the machined surface by more than 40Hv and improves surface state.

Description

The precise machining device of conical seat surface of ferrule tube fitting and processing method
Technical field
The present invention relates to a kind of processing technique field of workpiece, especially for the processing unit (plant) and the processing method of the conical surface.
Background technology
The sealing property of ferrule-type compression joint depends on the crudy of conical seat surface to a great extent, and the angle of the conical surface has two kinds, single deck tape-recorder cover 24 degree, and two cutting ferrule 30 degree, the quality restraining factors of the conical surface have 3
Figure G2009100329785D00011
Aspect: 1, surface roughness, 2, angle precision, 3, the hardness of poppet surface.
The method of the existing processing conical surface is to process the conical surface with Metal Cutting Machine Tool by Tool in Cutting, and tapering forms by feed, so precision and surface roughness are all undesirable, the more important thing is that machining can not improve case hardness, improves the poppet surface state.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned the deficiencies in the prior art, and provides a kind of conical surface surface roughness low.Conical surface angular accuracy height and improve the cone face process device and the processing method of poppet surface hardness simultaneously.
For solving the problems of the technologies described above, the precise machining device of conical seat surface of ferrule tube fitting of the present invention, comprise the roller that contacts with the joint conical seat surface and rotatable and can prolong the main shaft of axial feed, described main shaft is provided with a ring support, this ring support is in order to supporting roller, the even cloth of each roller symmetry is around main shaft, and the center of roller is on the same conical surface.
The conical surface that the outer rim bus of described roller forms is identical with the tapering of the conical seat surface of joint.
Described roller is cylindrical or conical roller.
The processing method of ferrule-type compression joint awl seat of the present invention is, after the roughing of cutting ferrule conical seat surface, described workpiece and main shaft is fixing respectively, and prolong the main shaft of the described precise machining device of conical seat surface axial feed, after roller and conical seat surface applying, workpiece and main shaft are produced relative rotation, by described roller to conical seat surface roll extrusion fine finishining.
The rotating speed of described main shaft changes roll extrusion degree of depth t=0.01-0.02mm for per minute 100-1000.
The present invention adopts the mode of roller crush and grind that conical surface finish rolling is processed, under the normal temperature state, part is exerted pressure, make matallic surface layer produce plastic deformation, revise the piece surface microcosmos geometric shape, the metallographic structure of parts list surface layer is changed, form favourable compression and distribute, improve the wearability and the hardness on surface.After the conical seat surface roughing, with a finish rolling of rolling head, the time can finish about 10 seconds, roll extrusion degree of depth 1-2 silk.
Compared with prior art, processing unit (plant) of the present invention is simple in structure, the processing method time is short, simple to operate, the roughness on the surface of processing rear cone is reduced to 0.8-0.1 from Ra6.3-3.2, and precision significantly improves, the Angular Dimension unanimity, case hardness after the processing can improve more than the 40Hv, has improved surface state.Simultaneously, apparatus of the present invention can be easily in common large, medium and small car, boring, bore, mill etc. on the lathe and carry out.
