Abstract
The utility model relates to a special screw puller for the dismantlement of special screw on frame opening mechanism's the connecting rod, this special screw connect soon and are equipped with the hexagonal hole in special nut and center, the rotatable setting of special nut on the connecting rod, its characterized in that: the puller is including dismantling seat, locking bolt and hexagonal spanner, but dismantles the recess that the seat was equipped with the housing connecting rod, is equipped with screw and through -hole respectively on the right both sides cell wall of this groove phase, and the locking bolt connects in the screw soon to forming axial displacement through rotating in the screw, making the tip sticis the corresponding one end at special nut, special nut is fixed, during the hexagonal spanner passes the hexagonal hole that the through -hole stretched into special screw, and drives the rotation that nut special was relatively done to special screw. The advantage is: the problem of loom opening mechanism's connecting rod dismantle often to use and destroy the connecting rod and lead to the fact the maintenance cost height as the cost is solved, a extracting tool for dismantling it is with low costs, work efficiency is high is provided.
Description
Technical field
This utility model relates to the instrument that loom is safeguarded, particularly for a kind of special screw puller on the connecting rod of textile machine shedding mechanism.
Background technology
The positive type of shedding mechanism of weaving machine returns to combine and is realized by a kind of linkage, this linkage such as Fig. 1,2, connecting rod 1 therein is a kind of thin-walled rectangular tube, connecting rod 1 has been connected by special cone screw 4 and tapered cup nut 3 and special bearing 2 with correlated parts, and on the both sides tube wall that rectangular tube two is relative, distinguish punching press taper hole, cone screw 4 and tapered cup nut 3 are respectively placed in the taper hole on the tube wall of side Nei and mutually spin, and special bearing 2 is then bearing on the conical surface, and this conical surface inner chamber forms described taper hole.
Loom is when daily maintenance and repair or replacing bearing 2, linkage have to be removed, and the core removing linkage dismantles cone screw 4 exactly, but when assembling this screw generally with regulation torque locking screw or add screw glue, therefore the torsion needed for knockout screw is big, and more troublesome is that often nut follows screw to rotate, and helplessly only firmly strikes, usually strike bad connecting rod, increase maintenance cost.
Summary of the invention
The purpose of this utility model is to provide a kind of puller not damaging connecting rod and energy convenient and swift dismounting special screw when dismantling, and above-mentioned purpose is achieved by following puller.
Described puller, the dismounting of special screw on the connecting rod of frame shedding mechanism, this special screw is rotatably connected in special nut and center is provided with hexagon ring, special nut is spindle rotationally arranged on connecting rod, wherein: described puller includes dismantling seat, clamping screw and die nut, described dismounting seat is provided with the groove that can accommodate part connecting rod, it is respectively equipped with screw and through hole on the both sides cell wall that this groove is relative, clamping screw is rotatably connected in screw, and moved axially by the formation of turn in screw, end is made to be pressed on corresponding one end of special nut, special nut is fixed, described die nut extend in the hexagon ring of special nut through through hole, and drive special screw to do rotating relative to special nut.
Further, in order to increase the intensity of both sides cell wall, the groove that described dismounting seat is provided with is U-shaped groove.
Further, described U-shaped groove is through U-shaped groove.
Further, screw and through hole that the both sides cell wall that described groove is relative is respectively provided with are coaxial string holes.
Further, the outer circumferential side of described clamping screw one end is hex surface.
Further, described clamping screw presses the diameter less than special nut corresponding end of the diameter in one end of special nut.
Further, the diameter of described through hole is more than the diameter of screw.
The beneficial effects of the utility model are: solve the connecting rod dismounting of shedding mechanism of weaving machine due to nut and screw transfer, and make dismounting often to destroy the problem that maintenance cost that connecting rod formed for cost is high, it is provided that the extracting tool that a kind of disassembly cost efficiency low, that work is high.

Fig. 2 is the linkage structural representation of shedding mechanism of weaving machine.
Fig. 3 is the parts explosion of linkage shown in Fig. 1.
Detailed description of the invention
Such as Fig. 1, special screw puller of the present utility model is the dismounting of special screw 4 on the connecting rod of frame shedding mechanism.In conjunction with Fig. 2,3, the center of special screw 4 is provided with the hexagon ring 41 for rotating this screw, and special nut 3 is to be spindle rotationally arranged on connecting rod 1, and special screw 4 is screwed on special nut 3.Puller of the present utility model is mainly made up of dismounting seat 5 and clamping screw 6 and die nut 7, dismounting seat 5 is provided with the groove 51 that can accommodate part connecting rod, screw 53 and through hole 54 it is respectively equipped with on the both sides cell wall 52 that this groove 51 is relative, clamping screw 6 is rotatably connected in screw 53, when dismantling the described special screw 4 on described connecting rod, the one end on connecting rod with special screw 4 and special nut 3 is placed in groove 51, and makes special nut 3 and special screw 4 be respectively toward to screw 53 and through hole 54.Turn clamping screw 6 is run through the motion of relative screw 53, and formation moves axially, and makes the end face A of clamping screw 6 be pressed on the corresponding end face of special nut 3.Die nut 7 extend in the hexagon ring of special screw 4 through through hole 54, rotates this die nut 7, and special screw follows rotation.The thrust being pressed on special nut correspondence end face due to clamping screw 6 is sufficiently large, consequent moment of friction be enough to offset special screw 4 and rotates the moment likely driving special nut 3 to follow rotation, so that special nut is fixed, thus special screw 4 can rotate relative to special nut 3, make both disengage spiral to connect, special screw 4 is removed, thus replaceable type bearing 2.
In order to strengthen the intensity of both sides cell wall 52 forming groove 51, groove 51 is U-shaped groove, and is that the vertical direction in U-shaped cross section with groove is through, is a through U-shaped groove.And the screw 53 being respectively provided with on the cell wall of both sides and through hole 54 are coaxial string holes, in order to the datum hole of this holes can disposably be processed.
Simultaneously in order to ensure that the pushing and pressing of special nut are acted only on special nut by clamping screw, clamping screw presses the diameter less than special nut 3 corresponding end of the diameter in special nut one end.And for turn clamping screw 6 easily, the outer circumferential side 61 of clamping screw one end is set to hex surface, or the centre bore 62 of clamping screw 6 is set to hexagon ring, in order to corresponding spanner turn clamping screw 6, it is allowed to special nut 3 one side shifting until being pressed on special nut 3.
Further, in order to ensure that the special screw 4 unloaded can preferably be taken out from connecting rod 1, the diameter D of through hole 54 is more than the diameter of special screw 4 maximum.
