Abstract
The utility model discloses a locking device of a screw stroke adjusting nut which makes the adjusting nut be not loosened on the frequent impacting condition. The device includes an adjusting nut which is arranged on the screw and which is matched and connected with the screw by a screw thread; the screw at the external side of the adjusting nut is provided with a locking nut which is provided with a locking cut and a locking hole which is matched with the locking cut; the locking hole is provided with a locking bolt; the adjusting nut and the locking nut are provided with at least one pair of guide pin holes; the two ends of the connecting pin are respectively moveably arranged in a pair of guide pin holes. The stroke adjusting device is mainly applied to the sites of adjusting angle for dual-head pipe bender, pipe contracting machine for adjusting pipe contacting length, and single-head pipe bender for adjusting the core pumping stroke.
Description
Technical field
The utility model relates to the controlling device of screw mandrel stroke, refers more particularly to the locking device of adjusting nut in the controlling device.
Background technique
Generally, the relative position in order to the adjusting nut of regulating the screw mandrel stroke on the screw mandrel needs locking, and screw mandrel all is according to the stroke work that regulates distance.But, in some particular application, as: the draw length adjustment of double-headed tube bender bend pipe angle adjustment, machine for shrinking, the stroke adjustment etc. of loosing core of single head tube bender, all need to add adjusting nut, adjust the stroke range that the front and back position of adjusting nut on screw mandrel changes screw mandrel with two removing from mould screw mandrels and in the rear end.The locking device of traditional adjusting nut as shown in Figure 3, Figure 4, an adjusting nut 62 is set on the screw mandrel 61 in needing the piston cylinder of adjustment stroke, offer a locking breach 64 and a silk with matching hole on the adjusting nut 62, silk is provided with bolt 63 in the hole.During work, at first adjust the position of adjusting nut 62 on screw mandrel 61, will lock breach 64 with bolt 63 after the position is determined and tighten up, thereby adjusting nut 62 is locked on the screw mandrel 61; In the working procedure, it is reciprocating that piston cylinder drives screw mandrel 61, screw mandrel 61 every to-and-fro motion once, adjusting nut 62 is just clashed into once, impact force directly acts on the adjusting nut 62, be easy to make adjusting nut 62 loosening like this, simultaneously because screw mandrel 61 also has the existence of rotation and screw mandrel helix angle in movement process, adjusting nut 62 also can produce relative rotation in knockout process, both of these case all can cause the position of adjusting nut 62 on screw mandrel 61 to change, influence the stroke range that regulates, thereby influence the quality of product of workpiece.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of under the situation of frequent bump, the locking device of the screw mandrel stroke adjustment nut that adjusting nut does not become flexible.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the locking device of described screw mandrel stroke adjustment nut comprises: the adjusting nut that is arranged on the screw mandrel and is connected by screw-thread fit with screw mandrel, on described screw mandrel, the outside of adjusting nut also is provided with a locking nut, offer locking breach and locking silk with matching hole on the locking nut, the locking silk is provided with lock bolt in the hole; Offer at least one pair of guide pin hole on adjusting nut and the locking nut, the two ends that connect pin are movably arranged on respectively in a pair of guide pin hole.
The further technological scheme of the utility model is to be provided with the gap between above-mentioned adjusting nut and locking nut.
In addition, also can be provided with graduation line by above-mentioned adjusting nut.And can above above-mentioned screw mandrel, also be arranged with scale in parallel.
The beneficial effects of the utility model are: owing to installed a locking nut additional in the outside of adjusting nut, and be movably set with between adjusting nut and locking nut and be connected pin; During work, at first clash into adjusting nut, impact force is delivered to locking nut by connecting pin then; The impact force that passes over through the connection pin obviously weakens, and it is loosening to be unlikely to make locking nut to take place, and has guaranteed the conformity of the each reciprocating stroke of screw mandrel, thereby has guaranteed the quality of product of processed piece.
Description of drawings
Fig. 1 is a main TV structure schematic representation of the present utility model;
Fig. 2 is the decomposition texture schematic representation of Fig. 1;
Fig. 3 is the structural representation of the locking device of the screw mandrel stroke adjustment nut described in the background technique;
Fig. 4 is the decomposition texture schematic representation of Fig. 3.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing, but the utility model should not only limit to this embodiment.
As shown in Figure 1 and Figure 2, the locking device of described screw mandrel stroke adjustment nut comprises: the adjusting nut 3 that is arranged on the screw mandrel 11 and is connected by screw-thread fit with screw mandrel 11, on screw mandrel 11, the outside of adjusting nut 3 also is provided with a locking nut 5, be provided with gap 45 between adjusting nut 3 and the locking nut 5, offer locking breach 52 and locking with matching silk hole 51 on the locking nut 5, the locking silk is provided with lock bolt 53 in the hole 51; Offer two pairs of guide pin hole on adjusting nut 3 and the locking nut 5, each two ends that connect pin 4 is movably arranged on respectively in a pair of guide pin hole.In the actual fabrication process, a disk 31 can be set at a side end of adjusting nut 3, be carved with the graduation line of some five equilibriums on the disk 31.In addition, in actual applications, the axial direction that also can be parallel to screw mandrel 11 directly over above-mentioned screw mandrel 11 is provided with scale 2; Be provided with the position that to adjust adjusting nut 3 behind the disk 31 that has graduation line and the scale 2 more easily.During work, at first make the lock bolt 53 of locking on the locking nut 5 in the silk hole 51 be in releasing orientation, rotate adjusting nut 3 then, locking nut 5 rotates synchronously with adjusting nut 3 under the drive that connects pin 4, after arriving the position of required adjusting with reference to the indication of scale 2, tighten lock bolt 53, draw locking breach 52 in, locking nut 5 is locked on the screw mandrel 11; Then, after starting piston cylinder 1, piston cylinder 1 drives screw mandrel 11 and does periodically to-and-fro motion, adjusting nut 3 is at first clashed in to-and-fro motion each time, impact force passes on the locking nut 5 by connecting pin 4 more then, again owing to be provided with gap 45 between adjusting nut 3 and locking nut 5, like this, the impact force that finally is delivered on the locking nut 5 has become very little, is unlikely to allow locking nut 5 loosening.As seen, the stroke adjustment of piston cylinder well just can not change afterwards, thereby has guaranteed machine performance.
