Abstract
A needle bar swinging device of a sewing machine is improved on the basis of an original needle bar swinging mechanism, a swinging frame guide block which can be movably adjusted up and down is added, the sizes of parts are correspondingly increased, the needle bar swinging frame is more stable in work, the consistency of needle pitch positions is ensured, and therefore sewing can be normally and effectively carried out particularly on thick materials.
Description
Technical field
The utility model belongs to the improvement of industrial sewing machine, particularly the improvement of industrial sewing machine shank pendulous device.
Background technology
Before the utility model is made, the shank swing of industrial sewing machine is fixed by original positioner, but when the thick material of sewing, because the shank pendulous device is than original length, rely on original body to be difficult to guarantee the unanimity of amplitude of fluctuation, more because the effect of inertia in the machine movement causes needle gage inconsistent, the needle downing position instability is so can not guarantee the carrying out of normal sewing.
The utility model content
The purpose of this utility model, be by improvement to original swing mechanism, increase, increase some part sizes in addition, the stopping means of shank swing span is moved down, to determine in a reasonable range, the stable of needle downing position thereby one of assurance needle gage is made peace is to guarantee that industrial sewing machine when making thick material, also can normally carry out work.
Above-mentioned purpose realizes by following technical proposals: the utility model is to utilize outside the compressor arm cover that is fixed on the casing to be with a shank swing span guide pad that increases newly, have a notch on the guide pad, insert shank swing span lower projection in its notch, both form matched in clearance, by regulating the screw on the shank swing span guide pad, guide pad is free to slide on demand within the limits prescribed up and down simultaneously.
The utility model has increased shank swing span guide pad because on prior art, make the shank pendulous device in the stitching sewing machine process especially when making than thick material, can only move within the specific limits.Thereby needle downing position is stable when effectively having guaranteed sewing, and needle gage is consistent, and has improved sewing quality, has avoided Sewing machines because of the excessive machine that damages of pendulous device hunting range.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
A kind of sewing machine needle bar pendulous device comprises the shank swing span 2 and the compressor arm 5 that are installed in the casing 1.Shank swing span 2 upper ends are inserted with shank swing span pin 3, and the lower end is connected with little presser feet 10 by swing depression bar 8.Compressor arm 5 tops are with overlaps 4 on the compressor arm, the bottom is with compressor arm and traps 7, and the lower tip of compressor arm 5 then is equipped with big presser feet 9.On shank swing span 2, also have and shank 12 that the 8 parallel connections of swing depression bar again can be up and down, pin folder 11 is equipped with in the lower end, and sewing needle is installed as required.Shank 12 is swung left crank 13 by shank and is connected with shank swinging axle 14; And be connected with last axle 15 by needle bar crank 16, sew up and down so that link with main frame.On compressor arm 5, generally trap and also be with a shank swing span guide pad 6 especially outside 7 at compressor arm, this guide pad 6 has a rectangle notch, insert shank swing span 2 lower projection in its notch, form matched in clearance, be free to slide within the limits prescribed,, realize the guide pad adjustment of height up and down simultaneously by regulating the screw on the shank swing span guide pad 6.
In order to adapt to the needs of the utility model shank pendulous device, shank swing span 2, compressor arm 5 and compressor arm trap 7, and parts such as swing depression bar 8 and shank 12 are all than the size that extended of corresponding part in original technology.
