Embodiment
The present invention is described in further detail below in conjunction with Figure of description and specific embodiment.
As depicted in figs. 1 and 2, the clamping device for Vehicle Processing thin-wall pipe of the present embodiment, including hollow fixation Axle 1 and at least two groups of support components 2, support component 2 include multiple support bars 21 being arranged circumferentially along fixing axle 1, support Bar 21 is extended radially through in fixing axle 1, and is threadedly coupled with fixing axle 1, and the end that support bar 21 is stretched out outside fixing axle 1 is provided with Support member 22.The one end of support bar 21 is located at outside fixing axle 1, and the other end is located in fixing axle 1, and by rotating support bar 21, can Regulation support bar 21 is located at the length of 1 outer one end of fixing axle.
In concrete application example, the quantity of support bar 21 is according to thin in the group number of support component 2 and every group of support component 2 The length and diameter of wall pipe fitting 3 are set.In the present embodiment, support component 2 is arranged to 3 groups, is axially uniformly arranged along fixing axle 1, 6 support bars 21 of every group of setting.
In use, support member 22 is fixed on the end of support bar 21, the screw thread for then stretching into support bar 21 in fixing axle 1 Hole(Not shown in figure)It is interior, rotation installation, according to the diameter of thin-wall pipe 3, the position of support bar 21 is mixed up, slightly compares thin-wall pipe 3 diameter is small, after installing all support bars 21, thin-wall pipe 3 is enclosed on outside support bar 21, now thin-wall pipe 3 Then support rotates support bar 21 by spanner, makes support bar 21 protruding on support member 22, it is thin to ensure that support member 22 is withstood The inwall of wall pipe fitting 3.When having operated all support bars 21 successively, it is ensured that each support member 22 withstands the inwall of thin-wall pipe 3.
The clamping device for Vehicle Processing thin-wall pipe of the present invention, is stretched by multiple can be radially into fixing axle 1 The support bar 21 gone out, for fixing thin-wall pipe 3, positioning stablity is reliable, the adjustable in length that support bar 21 stretches out, can both fit For the less thin-wall pipe 3 of diameter, the clamping for the thin-wall pipe 3 being relatively large in diameter that is particularly suitable for use in.It is uniformly arranged multigroup support Component 2, it is advantageously ensured that the positioning of thin-wall pipe 3 is firm, prevent the rocking in cutting process of thin-wall pipe 3, resilience And deformation, moreover, both gone for the less thin-wall pipe 3 of axial length, it is readily applicable to larger thin of axial length Wall pipe fitting 3, the characteristics of clamp structure is simple, easy to use, clamping effect is good, and versatility is good.
In the present embodiment, the part that support bar 21 is stretched out outside fixing axle 1 is additionally provided with locking nut 23, and locking nut 23 is close The outer wall of fixing axle 1 is set, and locking nut 23 is used to prevent the stress damaged screw after regulation in place of support bar 21, fixes simultaneously Support bar 21.
In the present embodiment, support bar 21 is provided with rotating nuts 24 between support member 22 and locking nut 23.Rotating nuts 24 coordinate with spanner, the convenient rotation to support bar 21.
In the present embodiment, multiple support bars 21 in every group of support component 2 are located in same sagittal plane, it is ensured that positioning can Lean on, uniform force.
In the present embodiment, be connected through a screw thread between support member 22 and support bar 21, by screw thread realize support member 22 with Be detachably connected between support bar 21, can according to demand or support member 22 damage when change support member 22.Support member 22 has The circle arc support face that can coordinate with the inwall of thin-wall pipe 3, so as to connecing therebetween when ensureing 22 top pressure thin-wall pipe 3 of support member Contacting surface is bonded completely, ensures positioning stablity, uniform force.In addition to the present embodiment, support member 22 and thin-wall pipe 3 can also be a little It is engaged.
In the present embodiment, 22 nonmetallic wear-resistant block of support member.In addition to the present embodiment, support member 22 can be ball or axle Hold.
Operation principle:
First by along one end of fixing axle 1 on lathe it is clamping, it is ensured that first group of support component 2 has necessarily apart from lathe three-claw 4 Distance is easy to adjust support bar 21, while the group of the radial direction upper support bar 21 of fixing axle 1 is determined according to the length of thin-wall pipe 3 Count and support bar 21 is installed, support member 22, it is to be ensured that the group number of support bar 21 is uniformly distributed, then according in thin-wall pipe 3 Footpath, the length that each support bar 21 stretches out fixing axle 1 is substantially adjusted, the circle diameter that every group of support member 22 is formed is compared thin-walled The internal diameter of pipe fitting 3 is somewhat a little bit smaller, then thin-wall pipe 3 is loaded in fixing axle 1 along the radial direction of fixing axle 1, and use lathe Tailstock 5 holds out against fixing axle 1.Finally, the length of all stretching of support bars 21 fixing axles 1 is adjusted by using torque wrench, makes support It is close in the circle arc support face of part 22(Hold out against)The inwall of thin-wall pipe 3, it is ensured that the clamping of thin-wall pipe 3 is firm.
Although the present invention is disclosed above with preferred embodiment, but is not limited to the present invention.It is any to be familiar with ability The technical staff in domain, in the case where not departing from technical solution of the present invention scope, all using the technology contents pair of the disclosure above Technical solution of the present invention makes many possible changes and modifications, or is revised as the equivalent embodiment of equivalent variations.Therefore, it is every Without departing from the content of technical solution of the present invention, according to the technology of the present invention essence to any simple modification made for any of the above embodiments, Equivalent variations and modification, it all should fall in the range of technical solution of the present invention protection.
