Described clamping oil cylinder afterbody and Connection Block are movably hinged; The front end of described clamping oil cylinder and slips holder are movably hinged.
Described slips holder is provided with positioning boss, and described slips is provided with corresponding to a watt groove for holder boss.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention adopts two groups of clamp mechanism that are arranged in parallel can meet compared with the clamping of the long drill pipe body of rod, and two clamping points meet the principle that two points make a line, prevent the deflection of the single clamp mechanism drilling rod body of rod, cause the malalignment of joint and body of rod friction welding center line.
2, the present invention adopts triangle slips halfbody to clamp the center line zero offset capability that can realize the drilling rod body of rod and joint friction welding, and production efficiency is high, constant product quality.
When 3, the present invention adopts the clamping of triangle slips halfbody can prevent joint and the friction of bar bar, the rotation of the body of rod, meets the requirement of positioning precision.
4, the present invention is in slips halfbody is arranged on slips holder and boss and groove location and position-limit mechanism are set, and intensity is high, location is reliable, replacing slips and overhaul convenient and swiftly, and holder moves steadily in slideway.
5, the present invention adopts hydraulic cylinder clamping chucking power large, and working stability is strong, and clamping is reliable.Supporting plate integral arrangement is on machine tool track, simple to operate, production efficiency is high, can realize automation mechanized operation.

The specific embodiment
Below in conjunction with accompanying drawing, by the specific embodiment, technical solution of the present invention is further explained to explanation.
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 guaranteeing 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 at holder, to move slideway 8 with clamping slips 5 and moves, clamping slips 5 halved bodies are separated, as shown in Figure 1, 2.
When needs friction welding (FW) clamps, cylinder piston rod stretches out, and drives slips holder 4 at holder, to move slideway 8 with clamping slips 5 and moves, and clamping slips 5 halved body closures realize drilling rod body 9 to clamp, as shown in Figure 3,4.
When phase mutual friction produces a large amount of heat, make rod end reach thermoplasticity state, during rapid upset, supporting plate 1 drives clamping device to the smithwelding of machine tool chief axis direction movable top, to connect on machine tool track 7.After completing friction welding, lathe supporting plate 1 drives clamping device to main shaft rightabout, to move on machine tool track 7.
