Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of handwheel of Sewing machines, particularly a kind of handwheel of the Sewing machines that eedle is stopped regulate the pin position.
Background technology
Existing sewing machine all comprises a horizontal platen, vertical support that vertical platen makes progress, the support top laterally towards a side extend horn and by the horn termination to the head that extends below.What be positioned at the installation of Sewing machines horn level goes up axle by drive power source such as direct driving motors, through a series of driving members, drives the shank at head position and the eedle of shank lower end and moves up and down.And can regulate the upper-lower position of eedle for the rotation that makes handwheel, often on the arbor of motor back, add handwheel, thereby manually rotation hand wheel just can drive axle and rotates and regulate the eedle height and manually sew.Therefore and Sewing machines must have the requirement that will stop or slow down because the sewing speed speed differs in the process of making, thus stop on the control eedle in good time or under to stop being indispensable function during Sewing machines is operated, the locomotive pin positioner of for this reason sewing arises at the historic moment.
Sewing locomotive pin positioner of the prior art; Generally all be placed on the head of sewing machine place; It mostly comprises a power transmission shaft, and power transmission shaft is fastening being installed on the head of sewing machine main shaft directly, and utilize two photoelectric sensors and upper and lower screening, printing opacity principle of stopping between the spill shield sheet of pin position; Offer the upper and lower needle position signal that stops of Sewing machines respectively, and control the pin that stops of Sewing machines through the rotation of Sewing machines handwheel.
Yet existing sewing machine car pin positioning device structure is complicated, and required amount of parts is more.And in adjustment process, to open end cap earlier, and stir the Sewing machines handwheel with the rotation machine spindle with hand, the observation needle position.Find stop the pin position after, need one to hold the Sewing machines handwheel, keep the eedle invariant position, another hand-screw pine is used for fixing the screw of usefulness, then on stop pin position spill shield sheet and regulate, again with screw-driving, and the end cap installation gone back after having regulated.Need under stop the pin position when regulating; Need repeat above-mentioned action again, operation is inconvenience very, and stop under the situation that pin position spill shield sheet all need regulate at upper and lower two; Operating personnel are difficult to guarantee that a hand is when regulating a spill shield sheet; Another hand still can be kept another spill shield sheet and keep motionless, and adjustment process is cumbersome, wastes time and energy again simultaneously.
Summary of the invention
The objective of the invention is the above-mentioned shortcoming that exists to existing technology, proposed a kind of simple in structurely, stop the handwheel that simple Sewing machines is regulated in the pin position.
The object of the invention can be realized through following technical proposal: a kind of handwheel of Sewing machines; Comprise being wheel body cylindraceous to have in the said wheel body and be used for the connection seat that links to each other with machine shaft, have the gap that air feed stream passes through between connection seat and the wheel body inboard; Said wheel body port also is fixedly connected with the cover plate with some passages; Said connection seat place axially is fixed with the off-position dish, has the off-position magnet on the said off-position dish, it is characterized in that; Be connected with adjusting gear on the said connection seat; Have arc-shaped rack on the said off-position dish, above-mentioned adjusting gear is meshed with arc-shaped rack and drives above-mentioned off-position dish rotation when adjusting gear rotates, and has the connection part that can link with instrument on the said adjusting gear.
Connecting portion through on instrument and the adjusting gear links; Turning tool just can make adjusting gear rotate; Drive off-position dish rotates with adjusting gear thereby the arc-shaped rack of adjusting gear on connection seat off-position dish is meshing with each other; After the off-position dish rotated, the off-position magnet positions on the off-position dish just can change, and only needed this moment the rotated position of off-position magnet just can be accomplished stopping the adjusting of pin position on the eedle to the desired position.And when stopping the pin position under the adjusting eedle, only need the program that combines programming good, in program, be provided with when handwheel turn to stop the pin position on the eedle after, again handwheel is turned over the following pin position of stopping that certain specific angle is an eedle.
In the handwheel of above-mentioned Sewing machines, have the adjustment hole of arc on the said off-position dish, above-mentioned arc-shaped rack is positioned at the adjustment hole side-walls, and above-mentioned adjusting gear is positioned at the adjustment hole place.
In the handwheel of above-mentioned Sewing machines, said adjusting gear connects firmly in an adjusting rod end, and adjusting rod axially connects firmly on cover plate and connection seat, and above-mentioned point of attachment is in the adjusting rod end.
In the handwheel of above-mentioned Sewing machines, have through hole one and through hole two on said connection seat and the cover plate respectively, above-mentioned adjusting rod is through at above-mentioned through hole one and through hole two, and above-mentioned point of attachment is in the cover plate outside.Point of attachment is conveniently adjusted in the cover plate outside, only needs instrument is connected with connection part to get final product, and need not to take off cover plate or other positions are dismantled.
In the handwheel of above-mentioned Sewing machines, said connection part and cover plate sidepiece flush.
In the handwheel of above-mentioned Sewing machines, said connection seat end has recessed retaining edge, is fixedly connected with jump ring on the above-mentioned connection seat, and above-mentioned off-position dish is pressed between jump ring and the retaining edge.The off-position dish is pressed between jump ring and the shelves edge, has prevented the axial float of off-position dish, has improved degree of regulation.
In the handwheel of above-mentioned Sewing machines, also having its section between said jump ring and the shelves edge is concavo-convex shell fragment.Shell fragment can slow down vibration, has certain cushioning effect.
In the handwheel of above-mentioned Sewing machines, said shell fragment is quadrangle, and the four edges of said shell fragment all has towards the recessed recess of same end face.The four edges of shell fragment has towards the recessed recess of same end face makes that the position of shell fragment is more firm, is difficult for loosening.
In the handwheel of above-mentioned Sewing machines, also be provided with packing ring between said shell fragment and the jump ring.
Compared with prior art, the handwheel of this Sewing machines has the following advantages:
1, the handwheel of this Sewing machines is only through utilizing cooperatively interacting between adjusting gear and the arc-shaped rack on the off-position dish on instrument, the adjusting rod, and is not only simple in structure, and easy to adjust, only needs a turning tool just can regulate the pin position of stopping of eedle.
2, the handwheel of this Sewing machines combines the programming of program on an off-position dish, realizes simultaneously make structure optimize more, and it being relatively low to process cost to upper and lower two adjustings that stop the pin position of eedle, has higher utility.
3, the handwheel of this Sewing machines utilizes jump ring, shell fragment and packing ring etc. that the off-position dish is fixed in the connection seat, has prevented the axial float of off-position dish, has guaranteed to have reduced regulating error to stopping the stability of pin position when regulating.
