Abstract
The utility model belongs to the field of oil tubes, and in particular relates to a riveting pressing structure for an oil tube of a turbocharger. The riveting pressing structure comprises a steel tube, a tube joint, a sleeve and a high-pressure tube, wherein the steel tube is pressed in one end of the tube joint; copper paste is coated between the steel tube and the tube joint for hydrogen protection brazing; at least one sealing groove and a sleeve fixing groove are formed in a peripheral surface of the tube joint; the sleeve is provided with a reversing stopping opening which is matched with the sleeve fixing groove; and the high-pressure tube is arranged between the sleeve and the tube joint in a riveting pressing manner. The riveting pressing structure has the advantages that effects of improving the riveting pressing performance and increasing the pulling-out force and the durability are achieved, the high-pressure tube is prevented from being worn, and the performance of the high-pressure tube is protected.
Description
Technical field
The utility model belongs to the oil pipe field, specifically a kind of turbosupercharger oil pipe rivet pressing structure.
Background technique
The operating temperature of turbosupercharger is very high, and the rotating speed of pressurized machine rotor when work is very high, can reach per minute tens0000 turns, so high rotating speed and temperature are so that common mechanical needle roller or ball bearing can't be working rotor, therefore turbosupercharger generally adopts the full floating bearing, need machine oil to be lubricated, the turbosupercharger oil pipe amounts to two pipelines, is respectively oil inlet pipe (the turbosupercharger oil purifier is to the pressurized machine pipeline) and return tube (pressurized machine is to the bottom sump pipeline).Oil inlet pipe is that the machine oil with certain pressure that transmission is crossed filtration through oil purifier lubricates the full floating bearing to pressurized machine.Return tube is to transmit through the pipeline of the machine oil behind the lubricated full floating bearing to fuel tank.The stainless joint of oil inlet pipe determines with adopting riveting form, rivet pressing structure being connected of high-voltage tube whether connection is safe and reliable, and rivet pressing structure was in case lost efficacy, the lighter causes leakage of oil, and turbocharger fails is driven difficulty, severe one causes the high-voltage tube explosion or takes off pipe, causes fire, causes car crash.
Summary of the invention
The utility model proposes a kind of turbosupercharger oil pipe rivet pressing structure for the deficiency that exists in the above-mentioned technology.
The utility model provides following technological scheme:
Turbosupercharger oil pipe rivet pressing structure; it comprises steel pipe, pipe joint, sleeve pipe and high-voltage tube; steel pipe is fitted in pipe joint one end; then Tu copper cream carries out the fine weldering of hydrogen shield between steel pipe and pipe joint; be provided with at least one sealed groove and sleeve pipe fixed groove on the side face of pipe joint; be provided with the seam that falls that cooperates with the sleeve pipe fixed groove on the sleeve pipe, the high-voltage tube riveting is between sleeve pipe and pipe joint.
Described sealed groove is provided with five.
Described sealed groove is leg-of-mutton sealed groove.
Described pipe joint end face is the circular arc end face.
Described pipe joint end is made as taper, and tapering is 15 °.
The utility model has the advantages that and improve the riveting performance, increased the effect of pulling-out force and endurance quality, play again preventing that high-voltage tube from galling, the effect of protection high-voltage tube performance.

Fig. 2 is the structural representation of the present utility model before the riveting;
Fig. 3 is the structural representation of the present utility model behind the riveting.
Embodiment
As Figure 1-3; turbosupercharger oil pipe rivet pressing structure; it comprises steel pipe 1, pipe joint 2, sleeve pipe 3 and high-voltage tube 4; steel pipe 1 is fitted in pipe joint 2 one ends; then Tu copper cream carries out the fine weldering of hydrogen shield between steel pipe 1 and pipe joint 2; be provided with at least one sealed groove 5 and sleeve pipe fixed groove 6 on the side face of pipe joint 2, be provided with the seam 7 that cooperates with sleeve pipe fixed groove 6 on the sleeve pipe 3, high-voltage tube 4 rivetings are between sleeve pipe 3 and pipe joint 2.
Described sealed groove 5 is provided with five.
Described sealed groove 5 is leg-of-mutton sealed groove.
Described pipe joint 2 end faces are circular arc end face 8.
Described pipe joint end is made as taper, and tapering is 15 °.
Structure as shown in Figure 1; pipe joint 2 is the welding core; material be stainless steel or carbon steel; turning has five triangle sealed grooves 5; seal; the end is processed as smooth circular arc end face 8, and 15 ° inclined-plane, has both played to be convenient to pipe joint insertion high-voltage tube; improve the riveting performance; increased the effect of pulling-out force and endurance quality or pulse number, played again preventing that high-voltage tube from galling, the effect of protection high-voltage tube performance; after welding core and steel pipe press-fit close-fitting; be coated with copper cream and carry out the hydrogen shield soldering, owing to adopting the hydrogen shield soldering, make the workpiece surface light; free from admixture and scale; as the material that welds core is that carbon steel needs through surface treatment--electroplated zinc nickel alloy, thickness are 10-15 μ, and salt spray test can reach 1000 hours without red embroidery.Then the stainless steel sleeve pipe is inserted in to the sleeve pipe fixed groove, as shown in Figure 2, adopt special tooling that high-voltage tube is filled in pipe joint, the high-voltage tube internal layer is PTFE, skin is that Φ 0.25mm Stainless Steel Wire is worked out for six roots of sensation diameter, at last, with special-purpose pressing mould riveting sleeve pipe, cannula tip is pressed into the sleeve pipe fixed groove, as shown in Figure 3, increased the pulling-out force of pipe fitting, this structure manufacturing is simple, economical and practical, safe and reliable.
