Embodiment Construction

[0024] Such as figure 1 As shown, the device of the present invention consists of a tool handle body 1, a rectangular pressure spring 2, an outer sliding sleeve 3, a positioning pin shaft 4, a core sleeve 5, a set screw 6, a rolling mandrel 7, a bearing sleeve 8, and an adjustment pad 9. Thrust ball bearing 10, turnbuckle 11, roller 12 are formed. in:

[0025] (1) The right end of the tool handle body 1 is a Morse taper shank, which can be installed in the taper hole of the tailstock sleeve of the machine tool and accurately centered. The left end of knife handle body 1 is cylinder-shaped, and its inner hole is slidingly matched with the outer diameter of core sleeve 5, and the two are connected by a positioning pin 4 passing through a waist-shaped groove in the middle part of core sleeve 5. Place the rectangular pressure spring 2 in the hole at the right end of the core sleeve 5, the right end of the rectangular pressure spring 2 contacts with the bottom of the knife handl...

Abstract

The invention relates to a high-precision elastic tapered bore rolling device of a cone sealing pipe joint, which belongs to a machine processing tool. The rolling device comprises a knife handle body, a rectangular pressure spring, an outer sliding sleeve, a locating pin roll, a core sleeve, a rolling mandril, a bearing sleeve, a thrust ball bearing, an adjusting pad, a flange sleeve and a roller. Compared with the traditional processing methods of drilling, internal boring and polishing, the production efficiency can be improved manyfold by adopting the rolling device to roll the conical surface inner bore of the cone sealing pipe joint; the surface roughness can be not more than Ra0.4 so that the requirements of a working drawing are stably reached, and the metal surface of the conicalsurface inner bore is strengthened, and thereby, the strength and the hardness of the surface layer are improved. The rolling device has good generality, and a rolling head fitting the size of the cone sealing pipe joint can be rapidly replaced. The elasticity of the spring can enable the changes of the axial force and the radial force which are borne by the rolling device in rolling the conical surface inner bore to be smaller; compared with a rigid rolling device, the abrasion of the rolling head of the rolling device is reduced, and thereby, the service life of the rolling device is prolonged by 3 to 5 times.

Description

technical field [0001] The invention belongs to mechanical processing tools, and relates to a high-precision tapered hole elastic rolling device, in particular to a high-precision tapered hole elastic rolling device for cone-sealed pipe joints. Background technique [0002] Cone seal pipe joints are mainly equipped with precision cone seals and are equipped with auxiliary seals such as O-rings (such as Figure 6 Shown), so the seal is reliable and stable, and is widely used in electromechanical, light industry, petrochemical and other industries, mainly used in hydraulic, pneumatic and instrument measurement of high and medium pressure transmission system pipelines with oil and gas as the medium. When the conical sealing pipe joint is used in the seamless steel pipe, water gas pipe (including various stainless acid-resistant steel pipes) system, it can avoid the harm caused by the leakage of liquid in the pipe during the production and processing of various instruments and eq...
