Description
Technical field
The present invention relates to a kind of Rhizoma Sparganii circular arc ribbed drill pipe friction welding (FW) body of rod clamping device.
Background technology
The structural shape of current domestic tunnel drill rod is mainly by bright finish drilling rod, rib drill stem, Rhizoma Sparganii circular arc ribbed drill pipe, and bright finish drilling rod, the joint of rib drill stem are round steel, and the body of rod is the steel pipe that joint cylindrical is the same.Joint uses friction welding to be connected with body of rod steel pipe, during friction welding (FW), joint round steel quickly rotates with machine tool chief axis, body of rod steel pipe is clamped on bed piece, by axial displacement and joint end contact bad student's frictional heat, carrying out clashing into upset after heat accumulates to certain limit and form friction welding seam, friction welding intensity high efficiency is high.And the joint section of the original convex drilling rod of Rhizoma Sparganii circular arc be triangular-section is triangle tube anchor ring with the body of rod.When using friction welding, joint can not be that triangle tube anchor ring contacts the most continuously with the section body of rod during rotating with machine tool chief axis, even if heat is to the requirement of friction welding (FW) temperature, during clashing into, it also is difficult to ensure that three limits of joint triangle are respectively with three limits of the body of rod at grade.The most numerous technical staff, have constantly descended many time from jackrod structure with process.Having many producers is that tool joint part to the structure of light rounded face drilling rod, is met the end face requirement of friction welding further through the reaming of body end, joint and body of rod welding position local recovery by the requirement meeting friction welding (FW).But the most unreasonable in triangle body of rod clamping and positioning mode, therefore friction welding technology is difficult on triangle drilling rod.
Summary of the invention
The weak point that the present invention exists in order to avoid prior art, it is provided that a kind of Rhizoma Sparganii circular arc ribbed drill pipe friction welding (FW) body of rod clamping device.
The present invention solves technical problem and adopts the following technical scheme that
Rhizoma Sparganii circular arc ribbed drill pipe friction welding (FW) body of rod clamping device, its construction features is, the supporting plate being slidably matched with end slipway is set, described supporting plate is provided above symmetrical clamp system, the left and right clamping part of described clamp system is by connecting seat, clamping oil cylinder, slips fixes seat and slips composition, described clamping oil cylinder afterbody is fixed on supporting plate by connecting seat, the front end of described clamping oil cylinder is fixed seat with slips and is connected, described slips is fixed seat and is moved slideway with fixing seat and be slidably matched, slips is detachably provided with the slips for radial direction holding drill pipe in fixing seat；Described clamp system axially arranged two groups along holding drill pipe body.
Present configuration feature also resides in:
The clamping cross section of described slips is half triangle, and the clamping face of slips is provided with crisscross groove.
Described clamping oil cylinder afterbody is movably hinged with being connected seat；The front end of described clamping oil cylinder is fixed seat with slips and is movably hinged.
Described slips is fixed seat and is provided with positioning boss, and described slips is provided with corresponding to a watt groove for fixing seat boss.
Compared with the prior art, the present invention has the beneficial effect that:
1, the present invention uses two groups of clamp systems that are arranged in parallel can meet the clamping of the relatively long drill pipe body of rod, and two clamping points meet the principle that two points make a line, prevents the deflection of single clamp system drill rod body, causes the malalignment of joint and body of rod friction welding centrage.
2, the present invention uses the clamping of triangle slips halfbody to be capable of the centrage zero offset capability of drill rod body and joint friction welding, and production efficiency is high, constant product quality.
3, the present invention uses the clamping of triangle slips halfbody to be prevented from the rotation of body of rod when joint rubs with bar bar, meets the requirement of positioning precision.
4, the present invention is arranged in slips fixes seat and arranges boss and groove location and position-limit mechanism at slips halfbody, and intensity is high, location is reliable, changes slips and overhauls convenient and swift, fixing seat stable movement in slideway.
5, the present invention uses hydraulic cylinder clamping chucking power big, 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.

Detailed description of the invention
By detailed description of the invention, technical solution of the present invention is further explained 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, it is arranged on machine tool track 7, supporting plate slides on machine tool track 7, and supporting plate 1 is provided above symmetrical clamp system, and clamp system is along axially arranged two groups of the Rhizoma Sparganii circular arc ribbed drill pipe friction welding (FW) body of rod；The left and right clamping part of each clamp system by connect seat 2, clamping oil cylinder 3, slips fixes seat 4 and slips 5 forms, clamping oil cylinder afterbody is movably articulated on supporting plate 1 by connecting seat 2, the engaging lug that the front end of clamping oil cylinder and slips fix seat 4 is movably hinged, and slips is detachably provided with the slips 5 for radial direction holding drill pipe in fixing seat；Fixing the robust motion of seat for controlling slips, arrange slips simultaneously and fix seat and move slideway 8 on supporting plate 1, slips is fixed seat and is moved left and right in slideway, controls drilling rod body 9 and unclamps and clamping, completes friction welding needs.
For ensureing connector center and drilling rod body central coaxial degree, slips 5 structure, as it is shown in figure 5, cross section uses half triangle, installs rear triangle geometric center and machine tool chief axis central coaxial.For increasing the frictional force in clamping face, prevent from rubbing upset time drilling rod slide slips 5 in, clamping face processes crisscross rectangle traverse furrow groove 10, as shown in Figure 6.Slips is fixing with slips installation to be fixed seat boss 12 coordinate as it is shown in fig. 7, processes on slips halfbody and install detent 11 with slips, meets slips and fixes seat installation positioning requirements with slips.Simultaneously for preventing slips from sliding in fixing seat, slips confined planes is set in slips fixes seat.Slips loads load connecting bolt 6 after slips fixes seat to be fixed, and completes holding drill pipe and the friction of joint and upset.
When drilling rod cylinder body needs to put into and take out after friction welding, cylinder piston rod is retracted, and drives slips to fix seat 4 and moves slideway 8 at fixing seat move with clamping slips 5, clamping slips 5 halved body separation, as shown in Figure 1, 2.
When needs friction welding (FW) clamps, cylinder piston rod stretches out, and drives slips to fix seat 4 and moves slideway 8 at fixing seat move with clamping slips 5, and drilling rod body 9 is realized clamping, as shown in Figure 3,4 by clamping slips 5 halved body Guan Bi.
Being made rod end reach hot plastic state when phase mutual friction produces substantial amounts of heat, during rapid upset, supporting plate 1 drives clamping device, and on machine tool track 7, to machine tool chief axis direction, movable top smithwelding connects.After completing friction welding, lathe supporting plate 1 drives clamping device to move to main shaft rightabout on machine tool track 7.
