As the preferred embodiment of technique scheme, be provided with internal thread at the inwall of described stepped hole macropore, be provided with external screw thread at the outer wall of described stop cover, the outer wall of this stop cover cooperates with the inner thread of described installing hole.By adjusting the distance between stop cover centre bore step surface and the stepped hole step surface, the size that can regulate each feeding.Here by threaded adjusting, in several scope of precision can being adjusted.
In technique scheme, the head of described lock sleeve and described collet pipe is a cone match; The head of described collet pipe upwards evenly is divided into 4 by radial slot in week.
Beneficial effect: the utility model is realized comparatively accurate measured length feeding with better simply structure, pass through flexible axle, by the parts moving linearly of main frame, or add the eccentric stiffener that is attached on the main frame by flexible axle and realize power supply, and can realize accurately with work period of main frame synchronously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the front view of collet pipe 5.
Fig. 3 is the left view of Fig. 2.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model is made up of pedestal 7, stop cover 2, collet pipe 5, lock sleeve 3, pulling block 1 and flexible axle hose, wherein on pedestal 7, be provided with lateral direction penetrating stepped hole 6, this stepped hole 6 is discharging opening, aperture and macropore from front to back, is provided with internal thread at the inwall of the macropore of this stepped hole 6.Collet pipe 5 has head 5a and the 5b of bar portion, wherein head 5a is positioned at stepped hole 6, this head 5a is the big taper of front end in the axial direction, and the external diameter of this head 5a front end is less than the aperture of stepped hole 6 apertures, this head 5a upwards evenly is divided into 4 in week, outer cover at this head 5a is equipped with lock sleeve 3, the front end of this lock sleeve 3 is and the identical taper hole of collet pipe 5 head 5a conical surface taperings, the back is the circular hole greater than the collet pipe bar 5b of portion size, lock sleeve 3 is a cone match with the head 5a of collet pipe 5, and the external diameter of lock sleeve 3 stops lock sleeve 3 to move forward greater than the aperture of stepped hole 6 apertures with the step by stepped hole 6.On the 5b of bar portion of collet pipe 5, be set with lock sleeve 3, the centre bore of this lock sleeve 3 is pre-large post-small stepped hole, the 5b of bar portion that the aperture of 2 centre bores and collet pipe 5 are overlapped in this stop movingly, and stop is overlapped the aperture of aperture of 2 centre bores less than the external diameter of lock sleeve 3, retreats to stop lock sleeve 3; Outer wall at stop cover 2 is provided with external screw thread, and the outer wall of this stop cover 2 cooperates with the inner thread of installing hole 6.The rear end of the 5b of bar portion of collet pipe 5 is inserted and is run through in the installing hole of pulling block 1, and fastening by screw.The flexible pipe 9 of flexible axle hose is installed on this pulling block 1, and the flexible axle 8 of flexible axle hose is installed on the described pedestal 7, and pulling block 1 with pedestal 7 relative motion takes place under the effect of flexible axle hose.On this pulling block 1, be provided with reset tension spring 10, reset tension spring 10 usefulness so that pulling block 1 reset.
The utility model operation principle is: during use, the other end of pedestal 7 and reset tension spring 10 is fixed on the support, collet pipe 5 is in the preparation feeding position.The flexible axle of flexible axle hose is affected by the eccentric stiffener that adds on main frame.
Preparing the feeding stage, flexible axle 8 is in relaxed state, the lock sleeve 3 and the collet pipe 5 that are enclosed within on the collet pipe 5 head 5a are return under the effect of back-moving spring 10 backward, stop motion when lock sleeve 3 motion touches stop and overlaps the step surface of 2 centre bores, and collet pipe 5 continues to retreat, under the effect of the lock sleeve 3 and the collet pipe 5 head 5a conical surfaces, the head 5a of collet pipe 5 will receive little and clamp wire rod 4.Flexible axle 8 begins to tighten up during feeding, and collet pipe 5 is pushed ahead by flexible pipe 9.Because the cone angle of lock sleeve 3 and the collet pipe 5 head 5a conical surfaces is less than from the locking angle, be in self-locking state, lock sleeve 3 can not loosen when collet pipe 5 travels forward, making head 5a grip wire rod 4 sends forward for one, the step surface that pushes up stepped hole 6 up to lock sleeve 3 stops to travel forward, and the head 5a of collet pipe 5 moves on, and breaks away from lock sleeve 3 wire rod 4 is unclamped, and stops sending wire rod 4.Wire rod 4 stops at and is fed to bit position under the effect of the frictional resistance of system.When flexible axle 8 was loosened once again, the head 5a of collet pipe 5 and lock sleeve 3 can be return under the effect of back-moving spring 10 again together, clamp wire rod 4 once again in new position.The 5 every reciprocating motions of collet pipe once, wire rod 4 is sent the length of a sizing.Overlap distance between 2 centre bore step surfaces and stepped hole 6 step surfaces, the size that can regulate each feeding by adjusting stop.Here by threaded adjusting, in several scope of precision can being adjusted.
The utility model can be from by obtaining power from the fork with the host work cycle synchronisation, perhaps obtain power from revolving part with the host work cycle synchronisation, work period as if the host part of obtaining power and main frame is synchronous, and then the utility model can be realized synchronous feeding.
