Embodiment

Below in conjunction with drawings and Examples the utility model threader is described further.

As shown in Figure 1 to Figure 3, threader of the present utility model comprises: frame 1, and the sidewall middle part is provided with bearing before and after the frame, and the quill shaft 2 of one and two bearings matched in clearance is located between the two bearings, the rear and front end stretches out in outside the frame, and is provided with locating

ring

21,22 in the position of front end and rear end; The coaxial hollow taper compression type chuck 23 that is provided with of the front end of quill shaft.

In frame, be provided with and drive the Power Drive Unit that quill shaft rotates and seesaws; As shown in Figure 2, Power Drive Unit comprises rectangular frame, is provided with axis hole on the framework minor face, and quill shaft wears within it; Be provided with a plurality of rollers in inboard, the long limit of framework, be shaped on the forward direction helical groove on the roller, be provided with belt pulley in rectangle frame one side, in order to be connected by belt transmission with motor.Like this, motor drives the forward and reverse rotation of quill shaft by the roller that belt pulley drives on the forward and reverse rotation of framework, the framework, and quill shaft is advanced in rotary course or retreats by helical groove.

Be provided with track in frame 1 front portion, at the front end of chuck 23, be provided with a bearing pedestal 3 that can slide before and after the track freedom, the internal diameter of this bearing pedestal inner bearing is provided with the external diameter at the middle part of compression type chuck 23 suitable; Bearing pedestal 3 both sides are provided with two springs 4 that are connected with frame front end both sides; Like this, utilize the pulling force of spring, lock steel wire in it, steel wire can be moved forward in rotation along with hollow shaft, chuck with the compressing chuck.

Be provided with bearing pedestal controlling organization 5 at the track front end, with so that chuck when arriving preceding dead point bearing pedestal not along with retreating, the position corresponding with locating ring in frame is provided with decontrol, in order to get back to the back at chuck during the dead point, removes the control of bearing pedestal controlling organization to bearing pedestal; As shown in Figure 1, bearing pedestal controlling organization 5 comprises: the bearing pedestal lock banking stop, it has two tension springs to hold on both sides, keep straight power at ordinary times, a backguy is arranged in the bottom of this sheet, be connected to the decontrol (not shown) that is contained in the track rear end, decontrol is and the releasing handle of lock banking stop by steel wire backguy interlock, be installed in the corresponding position of track rear end and locating ring 21, when quill shaft retreats to the dead point, back, touch and remove handle by backguy pulling bearing pedestal lock banking stop, to remove control to bearing pedestal.

Be provided with steel wire one-way locking device 8 at track front end and the corresponding position of chuck, as shown in Figure 3, it is made up of chuck, pressure ring and spring, with so that chuck when under the drive of quill shaft, retreating, clamp steel wire by it, steel wire can not be retreated, and when chuck drive steel wire advances, then inoperative to steel wire.

Be provided with

travel switch

71,72 and 72, rotatablely moving and seesawing at the antetheca of frame and rear wall and the corresponding position of quill shaft locating ring in order to the control Power Drive Unit.

The course of work of threader of the present utility model is: earlier with the wearing forward by quill shaft 2 rear portions of the steel wire on the steel wire wheel disc, pass through chuck 23, at this moment, start the switch that advances on the motor, motor drives rectangular frame by belt pulley and rotates, the grooved roller drive quill shaft 2 that is contained on the frame is done spiral rotation, quill shaft rotatablely moves along before the screw thread rotation direction, at this moment chuck 23 reaches, its head gos deep in the bearing of bearing pedestal 3, along with the reach of chuck 23, bearing pedestal 3 also begins reach along track, the pulling force of the spring 4 of bearing pedestal 3 both sides begins to strengthen, and until pressing chuck 23 ends more tight, makes chuck 23 be with steel wire to move forward while rotating; When bearing pedestal 23 when track moves to the bearing pedestal lock banking stop of front, press before with lock banking stop bearing pedestal 23 bottoms, and lock banking stop is moved forward, up to advancing to above lock banking stop, lock banking stop is return under the effect of spring, and bearing pedestal is blocked, and makes it to retreat; And in steel wire advances process, inoperative, promptly allow steel wire to pass through.Meanwhile, reach locating ring 22 touches travel switch 71, and motor is rotated in the opposite direction, and the threading stroke finishes, move after quill shaft 2 beginnings, at this moment 8 in steel wire one-way locking device is being controlled steel wire and is not made thereafter and move, and bearing pedestal 23 can not move under the lock banking stop effect, moves behind the quill shaft, chuck does not have the pulling force of spring, dop portion loosens, so when moving behind the quill shaft 23, steel wire stands fast; When moving shake-up releasing handle behind the locating ring, remove handle and drive the lock banking stop action by backguy, release is to the control of bearing pedestal, bearing pedestal behind the track of the drive lower edge of spring the road to clip position, meanwhile, travel switch 72 is positioned and encircles 21 shake-up, motor begins to move in the opposite direction, and return-stroke finishes, and the threading stroke begins, so repeatedly, finish until the threading process.
