Detailed description of the invention
As Fig. 1, shown in Fig. 4, the utility model provides a kind of chasing bar for horizontal boring machine, comprise guide pin bushing 10, pullover 20, screw tap cutting ferrule 30, screw tap 40, wherein guide pin bushing 10 is fixedly connected with pullover 20, on pullover 20, one end of guide pin bushing 10 is provided with link 21, link 21 is fixedly attached on boring spindle, screw tap cutting ferrule 30 one end is fixedly connected with screw tap 40, guide pin bushing 10 side opening is provided with oval hole 13, screw tap cutting ferrule 30 offers radial hole 35 away from the one end side of screw tap 40, described screw tap cutting ferrule 30 stretches in guide pin bushing 10 away from one end of screw tap 40, described radial hole 35 is plugged with the gag lever post 36 running through oval hole 13.
The movement locus of effect to gag lever post 36 of technique scheme middle part of the side circular hole 13 retrains, make the screw tap cutting ferrule 30 of fixing screw tap 40 can along oval hole 13 transverse shifting, to after preprocessing hole tool setting during tapping, screw tap 40 rotates in a circumferential direction, rotary motion preprocessing hole along with screw tap 40 can produce the internal thread corresponding with screw tap 40 external screw thread gradually between screw tap 40, now screw tap 40 will produce downward displacement by screw thread constraint, because screw tap cutting ferrule 30 is in quick condition by oval hole 13 constraint, thus axial feed motion can be produced by self adaptation screwing operation, thus realize screwing operation.
Further, screw tap 40 shank is fillet cylinder 41, screw tap cutting ferrule 30 is provided with the blind hole 31 holding screw tap 40, and described blind hole 31 end is interconnected with the radial location hole 32 being opened in screw tap cutting ferrule 30 side; Screw tap cutting ferrule 30 side is provided with annular groove 32, and the number in described radial location hole 32 is two or four, and described radial location hole 32 is symmetrically distributed in bottom annular groove 32; Any two symmetrical radial location holes 32 have been threaded screw tap cutting ferrule 30 bolt 34.During use, be that fillet cylinder 41 is inserted in blind hole 31 by screw tap 40 shank, compress by being arranged on bolt 34 pairs of fillet cylinders 41 symmetrical on radial location hole 32 again, thus realize the fixing of screw tap cutting ferrule 30 pairs of screw taps 40, the effect of annular groove 32 be avoid screw tap cutting ferrule 30 in guide pin bushing 10 in moving process bolt 34 and guide pin bushing 10 inwall produce and rub, affect screwing operation.
In the above-described embodiments, as shown in Figure 2 and Figure 3, guide pin bushing 10 both sides are respectively guide pin bushing stiff end 11 and guide pin bushing openend 12, wherein guide pin bushing stiff end 11 has external screw thread, pullover 20 have pullover openend 22 near guide pin bushing 10 side, and described pullover openend 22 has the internal thread adapted with guide pin bushing stiff end 11 external screw thread.During use, screw tap cutting ferrule 30 stretches in guide pin bushing 10 from by guide pin bushing openend 12, and guide pin bushing 10 is threaded with pullover 20 by guide pin bushing stiff end 11.
Further, in Figure 5, screwed hole 23 is provided with bottom pullover openend 22, the thread rotary orientation of screwed hole 23 and the internal thread rotation of pullover openend 22 are to contrary, chasing bar also comprises clamping screw 50, and clamping screw comprises nut 51 and screw rod 52, and screw rod 52 has the external screw thread adapted with screwed hole 23, clamping screw 50 runs through guide pin bushing stiff end 11 and is threaded with screwed hole 23, in order to the fixed effect of clamping screw 50 can arrange packing ring 60 between nut 51 and guide pin bushing 10.During owing to carrying out moving back after tapping completes thread, chasing bar will reversely rotate, simple employing guide pin bushing stiff end 11 and pullover 20 fixed forms be threaded, chasing bar is moving back in an operating process problems that guide pin bushing 10 and pullover 20 can occur and loosen, thus increase clamping screw 50 pairs of guide pin bushings 10 to be fixed with pullover 20, because the thread rotary orientation of screwed hole 23 and the internal thread rotation of pullover openend 22 are to contrary, can guarantee to move back between silk operation guide pin bushing 10 and pullover 20 without relatively rotating.
Below in conjunction with the operating procedure in production process, above-described embodiment is further elaborated.First, screw tap 40 is inserted in the blind hole 31 on screw tap cutting ferrule 30, uses bolt 34 pairs of screw taps 40 to be fixed; Then, guide pin bushing 10 is fixed by guide pin bushing stiff end 11 and pullover 20 screw threads; Again, fixed through guide pin bushing 10 and screwed hole 23 screw thread bottom pullover openend 22 by clamping screw 50; Finally, screw tap cutting ferrule 30 is stretched into guide pin bushing 10 by guide pin bushing openend 12, gag lever post 36 is inserted in radial hole 35 through oval hole 13, the assembling of chasing bar can be completed, then link 21 is fixedly attached on boring spindle, can screwing operation be carried out.
