The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
As depicted in figs. 1 and 2, stay pipe to be processed 50 two ends all are mounted with the not flange 51 of welding, offer bolt hole on the flange; Pull bar 100 is arranged in the stay pipe 50 to be processed, and stay pipe 50 to be processed is stretched out at the two ends of pull bar 100, and its extension offers respectively screw thread 102; Also be symmetrically arranged with round boss 110 on the pull bar 100, round boss 110 forms integrative-structure by welding and pull bar 100, and the position of round boss 110 on pull bar 100 is positioned at stay pipe 50 to be processed.
As shown in Figure 3, tapered sleeve 200 is in axial direction carried out the line cutting of five equilibrium, obtain six tapered sleeve pieces 201 that shape is identical; On three in six tapered sleeve pieces 201 round boss 110 that are placed in stay pipe 50 draw-in bars 100 to be processed, the circumferencial direction along stay pipe 50 to be processed between three tapered sleeve pieces is evenly distributed, and forms a cone space; Use the same method and other three tapered sleeve pieces are installed in the other end of pull bar 100.
As shown in Figure 4 and Figure 5, circular pressing plate 300 comprises a gland 330, gland 330 is level and smooth towards the end face in the outside, it matches towards flange 51 1 sides and end face of flange and is incorporated in the center and is provided with vertically a cone boss 340, cone boss 340 is the pyramidal structure that sectional area diminishes gradually towards flange 51 1 sides, cone boss 340 stretches into flange 51 endoporus and extends in the stay pipe 50 to be processed, and the cone space that forms with tapered sleeve piece 201 closely cooperates.
Circular pressing plate 300 centers offer unthreaded hole 310 vertically, go back the groove 311 that fit key 102 also is provided with a rectangle on the unthreaded hole 310, circular pressing plate 300 is set in pull bar 100 two ends by unthreaded hole 310, and it is fixed by key 102 with the relative position between the pull bar 100; The circular pressing plate 300 outside position of peripheral region and flange 51 bolts hole offers pin-and-hole 320 accordingly, pin-and-hole 320 on two circular pressing plates 300 is identical with the relative position of groove 311, the circular pressing plate 300 at two ends and the circumferential position between the flange 51 are determined by pin-and-hole 320 respectively, and it is fixing to plug alignment pin 322.
Be screwed with respectively 103, two nuts of nut 103 on the screw thread 102 at pull bar 100 two ends simultaneously towards flange 51 1 side screw propulsions, compress the circular pressing plate 300 at two ends by packing ring; The gland 330 of circular pressing plate 300 pushes against flange 51 and the middle stay pipe to be processed 50 at two ends; The cone boss 340 of circular pressing plate 300 pushes against tapered sleeve piece 201, and tapered sleeve piece 201 is subject to cone boss 340 extruding and expansion, thus the inwall of stretching stay pipe 50 to be processed internally.
The utility model is at first vertically placed pull bar 100 when assembling, and stay pipe 50 to be processed is sleeved on the pull bar 100, and three tapered sleeve pieces 201 of average arrangement on the round boss 110 of pull bar 100 are at keyway 101 interior arrangement keys 102; Successively mounting flange 51 and circular pressing plate 300, because the unthreaded hole 310 at circular pressing plate 300 centers is provided with groove 311, the circumferential position between circular pressing plate 300 and the pull bar 100 is definite by key 102; Rotate flange 51, the position of pin-and-hole 320 on the position of any one bolt hole on the flange 51 and the circular pressing plate 300 is overlapped, and be plugged alignment pin 322, the circumferential position between flange 51 and the circular pressing plate 300 is definite at this moment; Then install with the parts of same method with pull bar 100 other ends; Tighten the nut 103 at two ends this moment, just the flange 51 of stay pipe 50 to be processed with two ends can be fixed.
Because the position of the keyway 101 at pull bar 100 two ends is symmetrical, the relative position on two circular pressing plates between pin-and-hole 320 and the groove 311 is all at the same straight line, flange fixing complete after, the position of its bolt hole is correspondence mutually.
Moreover, since six tapered sleeve pieces for from same tapered sleeve through waiting minute cutting to obtain, the size between six tapered sleeve pieces all equates; Tapered sleeve piece 201 every triplets are evenly arranged in pull bar 100 two ends, and after compressing by circular pressing plate 300, tapered sleeve piece 201 can guarantee between pull bar 100 and flange 51, the stay pipe to be processed 50 coaxial in stretching stay pipe 50 inwalls to be processed.Welding flange 51 and stay pipe 50 to be processed and finish turnings this moment.
Moreover, because this device all is arranged on stay pipe to be processed 50 inside, not affecting welding and finish turning between flange 51 and the stay pipe to be processed 50, clamping work pieces in the bolt hole of location two end flanges 51 so that whole process can once be finished, need not to turn around; Owing to adopt the operation hole first in welding, need not to dig out dell on the drilling machine next door, saved greatly procedure of processing, removed the step of duplicate measurements, centering, promoted efficient and machining accuracy.
