Description
Technical field
The present invention relates to Sewing machines field, particularly relate to a kind of Sewing machines dials of liftable multimachine pin.
Background technology
The eedle of Sewing machines easily damages, and in quantity-produced process, during as changed eedle, just need to stop, this brings very large impact to quantity-produced product; And sometimes, for Production requirement, also will change the eedle of different model, the process changed back and forth is very loaded down with trivial details, brings great inconvenience to production; And different length eedle, need highly to regulate it, meanwhile, also need to ensure not loosen and not off normal, this just brings very large workload, wastes time and energy.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of Sewing machines dials of liftable multimachine pin.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Sewing machines dials of liftable multimachine pin, it comprise eedle dish, internal thread swivel nut, with externally threaded round outside but spuare inside sliding sleeve and fixed bar; Wherein, the bottom surface of described eedle dish circumferentially arranges multiple eedle storage tank; Flipping block is provided with in the one end at the center away from eedle dish of described eedle storage tank; Described flipping block is fixed on the inwall of eedle storage tank by rotating shaft; One end that described flipping block overturns outside eedle dish is fixed with eedle; The top of described flipping block is provided with operating block; One end of described operating block is stretched out from the side of eedle dish; The back-up block for propping up flipping block and firm eedle is also provided with between the other end of described operating block and the inwall of eedle dish; Described operating block is connected by spring with back-up block; Described back-up block is connected by another spring with the inwall of eedle dish; The upper surface of described eedle dish is provided with multiple stopper slot; Described internal thread swivel nut is arranged on directly over eedle dish; The lower end of described sliding sleeve is by the inner side of external thread rotary at internal thread swivel nut; The upper end of described sliding sleeve is fixed on head of sewing machine; The outside of the lower end of described internal thread swivel nut is also rotary with swivel nut holder; Described fixed bar to be located in internal thread swivel nut and to be connected with eedle dish by bearing; The middle reaches of described fixed bar are provided with boss; Described boss is folded between internal thread swivel nut and swivel nut holder, and is contacted with both respectively by ball; Described fixed bar is set to square slide bar on boss; Described square slide bar is located in sliding sleeve; The fixed bar that swivel nut holder is exposed in the below of described boss is provided with limited support bar; Described limited support bar is equipped with gag lever post; Stopper slot on described gag lever post and eedle dish with the use of.
When described spring is in impaction state, back-up block is away from the position of flipping block.
The position, middle reaches of described internal thread swivel nut is provided with convenient rotate and the cam be integrated with internal thread swivel nut.
The arranged outside of described cam has concave convex texture.
Operation principle of the present invention: the upper end of sliding sleeve is arranged on head; Required eedle is arranged on flipping block, and is recovered in eedle storage tank; Then, square slide bar on fixed bar is aimed at sliding sleeve according to actual station, eedle is checked and regulated body is spun on sliding sleeve lower end by internal thread swivel nut, the operating block of eedle dish side is stretched out in pressing, and operating block can promote one end of flipping block and holddown spring path that back-up block is overturn away from flipping block; The other end of flipping block is then outwards routed up with eedle; When eedle is routed up completely, unclamp operation block; Spring recovers relaxed state, and corresponding back-up block is replied initial position and propped up flipping block; Gag lever post passes limited support bar and is inserted in stopper slot; Then, rotating female screw swivel nut; Now, due to the position-limiting action of gag lever post, eedle dish is motionless relative to fixed bar, and the square slide bar of fixed bar is through in round outside but spuare inside sliding sleeve, makes fixed bar to move up and down and can not horizontally rotate, the boss of fixed bar to be clipped between internal thread swivel nut and swivel nut holder and to be contacted with both by ball, internal thread swivel nut can only be horizontally rotated, in conjunction with above effect, when making rotating female screw swivel nut around fixed bar, fixed bar can be made to drive the lifting of eedle dish, reach the object regulating height; If need to change eedle, pressing operation block, operating block can promote one end of flipping block and holddown spring path that back-up block overturn away from flipping block, is pressed back by eedle in eedle storage tank, while unclamp operation block; Then, extract gag lever post, whirler dials, the eedle needed is adjusted to station place and releases, then, insert gag lever post and eedle dish 1 is fixed; As height need be regulated, regulate by preceding method, after adjustment completes, proceed to produce, in the process of production, due to back-up block hold eedle, eedle dish held by gag lever post, fixed bar forbidden by boss moves up and down and horizontally rotating of fixed bar forbidden by square slide bar, eedle is not loosened, not off normal, and do not need to reorientate and dismantle, the replacing of eedle can be realized.
Advantage of the present invention: the Sewing machines dials of a kind of liftable multimachine pin of the present invention is under the condition do not dismantled, can eedle be changed, not need to reorientate, as height need be regulated, direct rotation, i.e. adjustable, and eedle does not loosen, not off normal, ensure that the demand that continuous seepage and multimachine pin are frequently changed greatly, easy to operate, time saving and energy saving.
