Detailed description of the invention
By detailed description of the invention, technical solutions of the utility model are further explained to explanation below in conjunction with accompanying drawing.
As shown in Figure 1, Rhizoma Sparganii circular arc ribbed drill pipe friction welding (FW) body of rod clamping device, supporting plate 1 is set, the bottom of supporting plate 1 arranges supporting plate length travel slideway 1a, be arranged on machine tool track 7, supporting plate slides on machine tool track 7, and supporting plate 1 top arranges and is symmetrical clamp mechanism, and clamp mechanism axially arranges two groups along the Rhizoma Sparganii circular arc ribbed drill pipe friction welding (FW) body of rod; The left and right clamping part of each clamp mechanism forms by Connection Block 2, clamping oil cylinder 3, slips holder 4 and slips 5, clamping oil cylinder afterbody is movably articulated on supporting plate 1 by Connection Block 2, the clamping front end of oil cylinder and the engaging lug of slips holder 4 are movably hinged, and are detachably provided with for the slips 5 of holding drill pipe radially in slips holder; For controlling the robust motion of slips holder, slips holder is set on supporting plate 1 simultaneously and moves slideway 8, slips holder moves left and right in slideway, controls drilling rod body 9 and unclamps and clamping, completes friction welding needs.
For ensureing joint center and drilling rod body center axiality, as shown in Figure 5, cross section adopts half triangle to slips 5 structures, and installation Vee formation shape geometric center is coaxial with machine tool chief axis center.For increasing the frictional force of clamping area, while preventing from rubbing upset, drilling rod is in the interior slip of slips 5, and clamping face is processed crisscross rectangle traverse furrow groove 10, as shown in Figure 6.Slips and slips are installed and are fixed as shown in Figure 7, and on slips halfbody, detent 11 is installed in processing, coordinates with slips holder boss 12, meet slips and with slips holder, positioning requirements are installed.For preventing that slips from sliding in holder, slips confined planes is set in slips holder simultaneously.After slips packs slips holder into, load connecting bolt 6 is fixing, completes friction and the upset of holding drill pipe and joint.
When drilling rod cylinder body need to put into and friction welding after while taking out, cylinder piston rod is retracted, and drives slips holder 4 to move slideway 8 with clamping slips 5 at holder and moves, clamping slips 5 halved bodies separate, as shown in Figure 1, 2.
In the time that needs friction welding (FW) clamps, cylinder piston rod stretches out, and drives slips holder 4 to move slideway 8 with clamping slips 5 at holder and moves, and drilling rod body 9 is realized clamping by clamping slips 5 halved body closures, as shown in Figure 3,4.
Make rod end reach thermoplasticity state when phase mutual friction produces a large amount of heat, when rapid upset, supporting plate 1 drives clamping device to connect to the smithwelding of machine tool chief axis direction movable top on machine tool track 7.After completing friction welding, lathe supporting plate 1 drives clamping device to move to main shaft rightabout on machine tool track 7.
