Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of handwheel of Sewing machines, particularly a kind of handwheel that eedle is stopped the Sewing machines regulated the pin position.
Background technology
Existing Sewing machines all comprises a horizontal platen, vertical support that vertical platen makes progress, and the support top is laterally towards side extension horn and by the head of horn termination to downward-extension.The upper axle that is positioned at the installation of Sewing machines horn level is driven by power sources such as direct driving motors, by a series of driving members, drives the shank at head position and the eedle of shank lower end and moves up and down.And regulate the upper-lower position of eedle for the rotational that makes handwheel, often the arbor in the motor back adds handwheel, rotates and regulates the eedle height and manually sew thereby the manual rotation handwheel just can drive axle.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, and stops on the eedle or lower stopping is indispensable function during Sewing machines operates so control in good time, and sewing machine needle location device arises at the historic moment for this reason.
Sewing machine needle location device of the prior art, generally all be placed on the head of sewing machine place, it mostly comprises a power transmission shaft, 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 respectively the upper and lower needle position signal that stops of Sewing machines, and control the pin that stops of Sewing machines by the rotation of sewing machine hand-wheel.
Yet, existing sewing machine needle location device complex structure, required amount of parts is more.And in adjustment process, to open first end cap, and stir sewing machine hand-wheel with the rotation machine spindle with hand, the observation needle position.Find stop the pin position after, need one to hold sewing machine hand-wheel, keep the eedle invariant position, another hand-screw pine is used for the fixedly 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, it is very inconvenient to operate, and stop in the situation that pin position spill shield sheet all needs to 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 purpose of this utility model is the above-mentioned shortcoming that exists for existing technology, has proposed a kind of simple in structurely, stops the handwheel that simple Sewing machines is regulated in the pin position.
The purpose of this utility model can realize by following technical proposal: a kind of handwheel of Sewing machines, comprise and be wheel body cylindraceous, has the connection seat that links to each other for machine shaft in the described wheel body, has the gap that air feed stream passes through between connection seat and the wheel body inboard, described wheel body port also is fixedly connected with the cover plate with some passages, described connection seat place axially is fixed with the off-position dish, has the off-position magnet on the described off-position dish, it is characterized in that, the described connection seat first line of a couplet is connected to adjusting gear, has arc-shaped rack on the described off-position dish, above-mentioned adjusting gear is meshed with arc-shaped rack and rotates when the adjusting gear rotational drives above-mentioned off-position dish, has the connection part that can link with instrument on the described adjusting gear.
Link by the connecting portion on instrument and the adjusting gear, turning tool just can make adjusting gear rotate, thereby the arc-shaped rack intermeshing drive off-position dish of adjusting gear on connection seat off-position dish rotates with adjusting gear, after the off-position dish rotates, off-position magnet positions on the off-position dish just can change, and only need turn to the desired position with the position of off-position magnet and just can finish stopping the adjusting of pin position on the eedle this moment.And when stopping the pin position under the adjusting eedle, only need in conjunction with the good program of programming, setting is after hand wheel rotating stops the pin position to eedle in program, and handwheel being turned over certain specific angle is the lower pin position of stopping of eedle again.
In the handwheel of above-mentioned Sewing machines, have the adjustment hole of arc on the described 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, described 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 respectively through hole one and through hole two on described connection seat and the cover plate, 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, described connection part is mutually concordant with the cover plate sidepiece.
In the handwheel of above-mentioned Sewing machines, described connection seat end has recessed gear 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 gear 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 described jump ring and the shelves edge is concavo-convex shell fragment.Shell fragment can slowing down vibration, has certain cushioning effect.
In the handwheel of above-mentioned Sewing machines, described shell fragment is quadrangle, and the four edges of described 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 so 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 described 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 by utilizing cooperatively interacting between adjusting gear on instrument, the adjusting rod and the arc-shaped rack on the off-position dish, 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 in conjunction with the programming of program, is realized upper and lower two adjustings that stop the pin position of eedle on an off-position dish simultaneously, so that structure optimizes more, and it is relatively low to make cost, has higher practical value.
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.
