The special screw removal device has the advantages that the problem that the maintenance cost is high because the removal of the connection rod of the opening mechanism of the weaving machine often needs destroying the connection rod is solved, and the removal device is low in removal cost and high in work efficiency.
Description
Technical field
The present invention relates to the instrument that loom is safeguarded, particularly relate to a kind of special screw stripping attachment 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 is as Fig. 1,2, connecting rod 1 is wherein a kind of thin-walled rectangular tube, connecting rod 1 and the connection of correlated parts have employed special cone screw 4 and tapered cup nut 3 and special bearing 2, and punching press taper hole is distinguished on the both sides tube wall that rectangular tube two is relative, cone screw 4 and tapered cup nut 3 are placed in respectively in the taper hole on the tube wall of side and also mutually spin, special bearing 2 is bearing on the conical surface, and this conical surface inner chamber forms described taper hole.
Loom is in daily maintenance and repair or when changing bearing 2, linkage must be removed, and the core of removing linkage dismantles cone screw 4 exactly, but when assembling this screw usually with regulation torque locking screw or add screw glue, therefore the torsion needed for knockout screw is large, and more troublesome is that often nut follows screw turns, helplessly only has and firmly strikes, usually strike bad connecting rod, increase maintenance cost.
Summary of the invention
Do not damage connecting rod when the object of this invention is to provide a kind of dismounting and the stripping attachment of the convenient and swift dismounting special screw of energy, above-mentioned purpose is achieved by following stripping attachment.
Described stripping attachment, 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 rotating to be arranged on connecting rod, wherein: described stripping attachment comprises dismounting seat, clamping screw and die nut, described dismounting seat is provided with can the groove of holding portion connecting rod, the both sides cell wall that this groove is relative is respectively equipped with screw and through hole, clamping screw is rotatably connected in screw, and moving 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, the screw that the both sides cell wall that described groove is relative is arranged respectively and through hole are coaxial string holes.
Further, the outer circumferential side of described clamping screw one end is hex surface.
Further, the described clamping screw diameter pressed in one end of special nut is less than the diameter of special nut corresponding end.
Further, the diameter of described through hole is greater than the diameter of screw.
Beneficial effect of the present invention is: solve the connecting rod dismounting of shedding mechanism of weaving machine due to nut and screw transfer, and make dismounting often to destroy the high problem of maintenance cost that connecting rod formed for cost, provide the extracting tool that a kind of disassembly cost efficiency that is low, work is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of stripping attachment of the present invention.
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
As Fig. 1, the dismounting of special screw stripping attachment of the present invention special screw 4 on the connecting rod of frame shedding mechanism.Composition graphs 2,3, the center of special screw 4 is provided with the hexagon ring 41 for rotating this screw, and special nut 3 is rotatingly arranged on connecting rod 1, and special screw 4 is screwed on special nut 3.Stripping attachment of the present invention forms primarily of dismantling seat 5 and clamping screw 6 and die nut 7, dismounting seat 5 is provided with can the groove 51 of holding portion connecting rod, the both sides cell wall 52 that this groove 51 is relative is respectively equipped with screw 53 and through hole 54, clamping screw 6 is rotatably connected in screw 53, when dismantling the described special screw 4 on described connecting rod, one end connecting rod with special screw 4 and special nut 3 is placed in groove 51, and makes special nut 3 and special screw 4 respectively facing to screw 53 and through hole 54.Turn clamping screw 6 makes it the motion by relative screw 53, and formation moves axially, and the end face A of clamping screw 6 is 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, and rotate this die nut 7, special screw follows rotation.The thrust be pressed on the corresponding end face of special nut due to clamping screw 6 is enough large, consequent moment of friction is enough to offset special screw 4 and rotates and likely drive special nut 3 to follow the moment of rotation, thus special nut is fixed, special screw 4 can be rotated relative to special nut 3 thus, make both throw off 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 through with the vertical direction in the U-shaped cross section of groove, is a through U-shaped groove.And the screw 53 that both sides cell wall is arranged respectively and through hole 54 are coaxial string holes, so that the datum hole of this holes can disposablely be processed.
Simultaneously in order to ensure that clamping screw only acts on special nut to the pushing and pressing of special nut, the clamping screw diameter pressed in special nut one end is less than the diameter of special nut 3 corresponding end.And in order to 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, with corresponding spanner turn clamping screw 6, to make it to move until be pressed on special nut 3 to special nut 3 side.
Further, in order to ensure that the special screw 4 unloaded can be taken out from connecting rod 1 preferably, the diameter D of through hole 54 is greater than the diameter of special screw 4 maximum.
