Description
Technical field
The utility model relates to a kind of multiplex lengthening turning tool rod, is specifically related to a kind of multiplex lengthening turning tool rod for the turning of steam turbine valve cage endoporus.
Background technology
Turbine high-pressure control valve and middle pressure control valve complex structure, comprising a lot of long sleeves, and the material of every kind of sleeve is also different, in process, the different sleeve endoporus of turning need to be with lengthening accordingly lathe tool, the lengthening lathe tool that this just need to customize according to actual processing plurality of specifications, comprises brazed carbide turning tool and the mechanically-clamped turning tool of the different cutter heads of different length.Lathe tool is expensive, has increased manufacturing cost, and the process lathe tool that repeatedly changes the outfit, and has increased procedure of processing, has reduced productivity ratio.
Utility model content
The utility model is in order to solve current turbine high-pressure control valve and middle pressure control valve complex structure, in process, need with multiple different lengthening lathe tool, increase manufacturing cost, and the process lathe tool that repeatedly changes the outfit, increase procedure of processing, the problem that productivity ratio reduces, and then a kind of multiplex lengthening turning tool rod for the turning of steam turbine valve cage endoporus is proposed.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: the utility model comprises extension bar, bolt, positioning sleeve and the first fishbolt, extension bar is cylinder, extension bar bottom sidewall in axial direction offers plane, on extension bar top end face, in axial direction offer the first tapped through hole, bolt and the first tapped through hole threaded engagement, between plane on extension bar and the first tapped through hole, radially offer perforation square groove, the first tapped through hole communicates with perforation square groove, described positioning sleeve comprises sleeve pipe, pinching end and the first fishbolt, pinching end is cuboid, pinching end is arranged on the lateral wall of sleeve pipe one side and makes one with sleeve pipe, on the lateral wall of sleeve pipe opposite side, radially offer the second tapped through hole, the second tapped through hole and the first fishbolt threaded engagement, positioning sleeve is affixed by the first fishbolt and extension bar.
The beneficial effect that the utility model compared with prior art comprises is:
1, the utility model design is small and exquisite, simple in structure, regulate the length of knife bar by positioning sleeve and extension bar, and then according to the effective length of the interior hole depth adjustment knife bar of processing work, make this knife bar replace plurality of specifications length lathe tool, reduce enterprise and prepared the cost of lathe tool, thereby reduced manufacturing cost.
2, the utility model is in the time that thick, finish turning are changed trains cutter, and lathe tool connects square groove place at extension bar and changes the outfit, positioning sleeve place does not need to adjust, saved cutter spindle to the adjustment of clamped position again, simplified procedure of processing, easy to use, quick, production efficiency improves 5%.
3, the utility model is applicable to the various stock size lathe tools of clamping and lengthens lathe tool, applied widely, practical, and easily manufactured, cheap for manufacturing cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model, and Fig. 2 is the right view of Fig. 1, and Fig. 3 is the structural representation of positioning sleeve 3, Fig. 4 be in Fig. 1 A-A to cutaway view.
Detailed description of the invention
Detailed description of the invention one: as Figure 1-4, described in present embodiment, a kind of multiplex lengthening turning tool rod for the turning of steam turbine valve cage endoporus comprises extension bar 1, bolt 2, positioning sleeve 3 and the first fishbolt 4, extension bar 1 is cylinder, extension bar 1 bottom sidewall in axial direction offers plane 1-1, on extension bar 1 top end face, in axial direction offer the first tapped through hole 1-3, bolt 2 and the first tapped through hole 1-3 threaded engagement, between plane 1-1 on extension bar 1 and the first tapped through hole 1-3, radially offer and connect square groove 1-2, the first tapped through hole 1-3 communicates with perforation square groove 1-2, described positioning sleeve 3 comprises sleeve pipe 3-1, pinching end 3-2 and the first fishbolt 4, pinching end 3-2 is cuboid, pinching end 3-2 is arranged on the lateral wall of sleeve pipe 3-1 mono-side and makes one with sleeve pipe 3-1, on the lateral wall of sleeve pipe 3-1 opposite side, radially offer the second tapped through hole 3-4, the second tapped through hole 3-4 and the first fishbolt 4 threaded engagement, positioning sleeve 3 is affixed with extension bar 1 by the first fishbolt 4.
Detailed description of the invention two: as Figure 1-4, described in present embodiment, positioning sleeve 3 also comprises the second fishbolt 5, on the sidewall of the sleeve pipe 3-1 opposite side on positioning sleeve 3, radially offer the 3rd tapped through hole 3-5, the second fishbolt 5 and the 3rd tapped through hole 3-5 threaded engagement.Other composition and connected mode are identical with detailed description of the invention one.So design, the second fishbolt 5 coordinates the first fishbolt 4 to carry out clamping and positioning to extension bar 1, has ensured the accuracy of clamping and positioning, guarantees crudy.
Operation principle
The utility model connects square groove 1-2 by conventional lathe tool is put into, adjust lathe tool angle and length, after bolt 2 is screwed in the top first tapped through hole 1-3 of extension bar 1, bolt 2 and lathe tool are offseted, play the effect of jackscrew, fix lathe tool, again positioning sleeve 3 is sleeved on extension bar 1, adjust knife bar length and angle by regulating positioning sleeve 3 and the relative position of extension bar 1, by the second fishbolt 4 and the second tapped through hole 3-4 threaded engagement, the second fishbolt 4 and the plane 1-1 of extension bar 1 are offseted, play clamping and positioning effect, make positioning sleeve 3 and extension bar 1 fastening, finally the pinching end 3-2 on positioning sleeve 3 is clamped on the blade row of lathe, process.
