Description
Technical field
The present invention relates to the instrument of loom maintenance, more particularly, to one kind on the connecting rod of textile machine shedding mechanism
Special screw stripping attachment.
Background technology
The positive type of shedding mechanism of weaving machine time is comprehensive to be realized by a kind of linkage, the linkage such as Fig. 1,2, company therein
Bar 1 is a kind of thin-walled rectangular tube, and connecting rod 1 and the connection of correlated parts employ special cone screw 4 and tapered cup nut 3 and special
With bearing 2, and distinguish on the relative both sides tube wall of rectangular tube two punching press taper hole, cone screw 4 is respectively placed in tapered cup nut 3
Spin in taper hole on the tube wall of side and mutually, special bearing 2 is then supported on the conical surface, and the conical surface inner chamber forms the taper hole.
Loom is in daily maintenance and repair or replacing bearing 2, it is necessary to removes linkage, and removes linkage
Core is exactly to dismantle cone screw 4, but generally with defined torque locking screw or adds screw glue when assembling the screw, therefore
Torsion needed for knockout screw is big, and more troublesome is that often nut follows screw to rotate, and helplessly only strikes firmly, usually strikes bad
Connecting rod, increases maintenance cost.
The content of the invention
It is an object of the invention to provide the dismounting for not damaging connecting rod and energy convenient and swift dismounting special screw during a kind of dismounting
Device, above-mentioned purpose is achieved by following stripping attachments.
The stripping attachment, the dismounting of special screw on the connecting rod of frame shedding mechanism, special screw is rotatably connected in spy
Different nut and center is provided with hexagon ring, special nut is spindle rotationally arranged on connecting rod, wherein：The stripping attachment includes dismounting
Seat, clamping screw and die nut, the dismounting seat provided with can accommodating portion connecting rod groove, the relative both sides cell wall of the groove
On be respectively equipped with screw and through hole, clamping screw is rotatably connected in screw, and by the axial movement that turn is formed in screw, makes end
Portion is pressed on corresponding one end of special nut, and special nut is fixed, and the die nut extend into special nut through through hole
Hexagon ring in, and drive special screw to do the rotation relative to special nut.
Further, in order to increase the intensity of both sides cell wall, the groove that the dismounting seat is provided with is U-shaped groove.
Further, the U-shaped groove is the U-shaped groove of insertion.
Further, the screw and through hole set respectively on the relative both sides cell wall of the groove is coaxial string holes.
Further, the outer circumferential side of described clamping screw one end is hex surface.
Further, the diameter that the clamping screw presses in one end of special nut is less than the straight of special nut corresponding end
Footpath.
Further, the diameter with diameter greater than screw of the through hole.
The beneficial effects of the present invention are：The connecting rod for solving shedding mechanism of weaving machine is dismantled due to nut and screw transfer,
And make dismounting often there is provided a kind of disassembly cost is low, work to destroy the problem of maintenance cost that connecting rod formed as cost is high
Efficiency high extracting tool.
Brief description of the drawings
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.
Embodiment
Such as Fig. 1, special screw stripping attachment of the invention is used for the dismounting of special screw 4 on the connecting rod of frame shedding mechanism.
With reference to Fig. 2,3, the center of special screw 4 is provided with the hexagon ring 41 for being used for rotating the screw, and special nut 3 is rotatable sets
On connecting rod 1, special screw 4 is screwed on special nut 3.The stripping attachment of the present invention it is main by dismounting seat 5 and clamping screw 6 and
Die nut 7 is constituted, dismounting seat 5 provided with can accommodating portion connecting rod groove 51, on the relative both sides cell wall 52 of the groove 51 point
Not She You screw 53 and through hole 54, clamping screw 6 is rotatably connected in screw 53, when dismantling the special screw 4 on the connecting rod,
The one end for having special screw 4 and special nut 3 on connecting rod is placed in groove 51, and makes 4 points of special nut 3 and special screw
Not against screw 53 and through hole 54.Turn clamping screw 6 is run through the motion of relative screw 53, forms axial movement, makes lock
The end face A of tight bolt 6 is pressed on the corresponding end face of special nut 3.Die nut 7 extend into special screw 4 through through hole 54
Hexagon ring in, rotate the die nut 7, special screw follows rotation.Because clamping screw 6 is pressed on special nut corresponding end
Thrust on face is sufficiently large, and resulting moment of friction, which is enough to offset special screw 4 and rotated, to be possible to drive special nut 3
The torque of rotation is followed, so that special nut is fixed, thus special screw 4 can be rotated relative to special nut 3, take off both
Spiral connection is opened, special screw 4 is removed, so that replaceable type bearing 2.
In order to strengthen the intensity for the both sides cell wall 52 to form groove 51, groove 51 is U-shaped groove, and to be cut with the U-shaped of groove
The vertical direction insertion in face, the U-shaped groove of as one insertion.And the screw 53 and through hole 54 set respectively on the cell wall of both sides is
Coaxial string holes, can disposably be processed so as to the datum hole of the holes.
Simultaneously in order to ensure that pushing and pressing of the clamping screw to special nut are acted only on special nut, clamping screw press in
The diameter of special nut one end is less than the diameter of the special corresponding end of nut 3.And for easily turn clamping screw 6, will lock
The outer circumferential side 61 of bolt one end is set to hex surface, or the centre bore 62 of clamping screw 6 is set into hexagon ring, to use correspondence
Spanner turn clamping screw 6, is allowed to the special side shifting of nut 3 one until being pressed on special nut 3.
Further, in order to ensure that the special screw 4 unloaded can be taken out preferably from connecting rod 1, the diameter D of through hole 54 is more than spy
The diameter of the different maximum of screw 4.
