It is of the invention that specific use process is as follows:
In the present embodiment, lathe bed is in horizontally disposed.Plug 6 is fixed on floral disc 407 and tailstock chuck 201, core is made
The axle center at 6 both ends of stick adjusts floral disc clamp 408 and tailstock card respectively against the first column thimble 203 and the second column thimble 409
Pincers 202 it is elastic, clamp plug 6 as far as possible under the premise of not destroying plug 6.Floral disc clamp 408 and tailstock clamp 202 are
Multijaw clamp, pawl number determine by actual demand, usually 3~4 pawl.Tailstock case 205 in tailstock mechanism 2 is two-layer stratigraphic structure,
Third profile shaft is respectively mounted at the cooperation of stud 206 Yu 205 wall surface two sides of tailstock case and holds 208, is used to support stud 206 and auxiliary
The rotation of 206 column of spiral shell.Internal layer can be made to move along cabinet direction by rotating third handwheel 210, finely tune the clamping of tailstock chuck 201
Position, tailstock case 205 can do the longer linear motion of stroke along tailstock guide, for substantially adjusting the folder of tailstock chuck 201
Hold position.205 internal layer of tailstock case is additionally provided with oiling groove, and oiling groove connects the bottom of pouring orifice 204, for guiding lubricating oil
Flowing.Since main shaft 404 and locating shaft 212 are rotatable axis body, therefore plug 6 after installation is complete can also be with main shaft 404
It is rotated coaxially with locating shaft 212.The position that main shaft 404 and locating shaft 212 need to be calibrated makes its level coaxial arrangement, and guarantees first
Column thimble 203 and the second column thimble 409 are also coaxial arrangement.To realize being freely rotated for locating shaft 212 and main shaft 404,
The first profile shaft is respectively mounted in the end of the junction and locating shaft 212 of locating shaft 212 and tailstock case 205 and holds 207, in main shaft 404
Third profile shaft is installed at the cooperation with spindle box 403 and holds 405.Spindle box 403 is hollow rectangular parallelepiped structure, and spindle box 403 pushes up
Case lid 410 is arranged in portion, and case lid 41 and the quadrangle at 403 top of spindle box are spirally connected, it may be necessary to open main shaft by backing out screw
Case 403, for the maintenance and maintenance to spindle box 403.
Upper guiding wheel arm 313 and lower guiding wheel arm 321 symmetrically open up an arc close to the side of guiding wheel carrier 303 and lack
Mouthful, for passing through and not interfering the rotation of plug 6 for plug 6.Rotate the first handwheel 311 and the second handwheel 312 it is adjustable on
The position of support arm 306 and lower support arm 304, for controlling the folding of upper guiding wheel arm 313 and lower guiding wheel arm 321.First
Handwheel 311 and the second handwheel 312 are connect by the second connector 310 with bearing with guiding wheel carrier 303, and bearing is to connector
Support and protective effect are played with each guide spiro rod, is provided with several in each upper guiding wheel arm 313 and lower guiding wheel arm 321
Directive wheel.First preferably embodiment is given in Fig. 4, as shown in figure 4, there are four production orientations for setting in each guiding wheel arm
Wheel: the first directive wheel 314, the second directive wheel 315, third directive wheel 316 and the 4th directive wheel 318 and three spare guiding
Wheel: the first spare wheel 317, the second spare wheel 319 and third spare wheel 320.Heat-transfer pipe 7 passes through each production orientation as shown in Figure 4
Wheel, directive wheel are distributed in 7 two sides of heat-transfer pipe alternatively up and down, and each directive wheel is turntable, and the periphery of each directive wheel is certainly
Two sides can accommodate the surface that heat-transfer pipe 7 passes through and do not damage heat-transfer pipe 7, in upper guiding to the smooth arc groove face of intermediate recess
Open up the strip-shaped groove being adapted to directive wheel quantity in wheel arm 313 and lower guiding wheel arm 321, the strip-shaped groove according to
Position difference is opened up with different inclination angles.Directive wheel is installed in the strip-shaped groove, and can be along the strip-shaped groove
Inclined direction adjust installation site.Spare idler wheel needs to remove when idle, is installed again when needing, spare idler wheel
Structure it is consistent with production orientation wheel, simple installation.The size of each production orientation wheel and spare idler wheel is selected according to actual condition
It selects, is usually gradually reduced along 7 direction of feed of heat-transfer pipe.Heat-transfer pipe 7 is sent into guiding mechanism 3 by heat-transfer pipe feed arrangement 501, leads
To mechanism 3 can with pre-bending heat-transfer pipe 7, make heat-transfer pipe 7 bending to wind when need around pipe radian.Due to the tube wall of heat-transfer pipe 7
It is relatively thin, caliber is thinner, it is excessive to may cause 7 local stress of heat-transfer pipe in the form of straight tube is directly wound, and tube body is made to generate change
The undesirable conditions such as shape, distortion, cracking, and heat-transfer pipe 7 is difficult to fit closely plug 6 or internal layer around tube layer when straight tube winding, and lead to
The effect for crossing multistage directive wheel can make the deformation process of heat-transfer pipe 7 continuous, soft, be oriented to wheel surface it is smooth and with heat-transfer pipe 7
Contact area is big, and 7 distortional stress of heat-transfer pipe can be made evenly dispersed.
Upper guiding wheel arm 313 and lower guiding wheel arm 321 do not work at the same time, due to upper guiding wheel arm 313 and lower guiding wheel arm
321 7 direction of feed of heat-transfer pipe is opposite with respect to the direction of rotation of main shaft 404, thus using upper when needing clockwise about pipe
It is oriented to wheel arm 313, lower guiding wheel arm 321 is selected when needing counterclockwise around pipe.Simultaneously as shown in figure 5, the bottom of guiding wheel carrier 303
It is connected with guide groove plate 322, guide groove plate 322 can be rotated around positioning screw 325, range and the arc groove 323 of rotation
Length range is identical.By adjusting the angle of guiding wheel carrier 303 and main shaft 404, multilayer can satisfy around pipe demand, when around tube layer
, may not be vertical with main shaft 404 around tube angulation when number increases, actual condition can be matched by rotary steering wheel carrier 303 at this time,
After having adjusted the angle of guiding wheel carrier 303 and main shaft 404, need to tighten fastening screw 324.
Startup power supply after above-mentioned items adjust is completed, main shaft 404 drives plug 6 to rotate, the vertical peace of spindle drive motor 401
Dress allows to drive the main shaft 404 being horizontally mounted by transmission case 402 come converting motion direction.Transmission gear 503 is being led
Rotated clockwise or counterclockwise under to the driving of mechanism driving-motor 502, and by with driving rack 506 engage band action-oriented
Linear reciprocating motion does along guide rail in mechanism 3, and the direction of linear motion influences inclined direction of the heat-transfer pipe 7 on plug 6 and around pipe
Pitch.For placing power supply line and control line in drag chain 505, prevents route impaired, route can also be reduced to motion process
