Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of Sewing machines lower shaft backlash regulator.
Background technology
Shaft assembly mainly is the sector gear that is connected with connecting rod and is that the lower shaft gear that supports is formed with the lower shaft under the existing sewing machine.In use, rotate, realize that under the effect of following shaft assembly lower shaft comes back rotation in the certain angle scope thereby the upward axle of Sewing machines rotates a drive lower shaft.
The following shaft assembly of this Sewing machines also comprises the needle bearing that is set on the lower shaft, and lower shaft and needle bearing are matched in clearance.Descending shaft assembly to come back rotation at a high speed like this, easily weares and teares in the cooperation place of lower shaft and needle bearing, after use a period of time, can produce the gap between lower shaft and the needle bearing, and As time goes on, it is big more to wear and tear, and the gap is also big more.This can bring a series of problems, as shakes greatly, the big needle tracking shakiness of noise, and linear slit is bad etc.And because the lower shaft of the following shaft assembly of bar tacking machine is a matched in clearance with cooperating of needle bearing, in order to reduce wear, needs often to add lubricating oil and be lubricated, cumbersome, also can pollute making thing.
For this reason, people design the lower axle structure of Sewing machines, and some has also applied for patent.For example: Chinese patent literature discloses a kind of lower shaft driving mechanism [publication number: CN1439760A] of Sewing machines, it comprises changes into the mapping device of oscillating motion with rotatablely moving of last axle, with be provided with mapping device be connected, be bearing in big balance staff on the sewing machine frame be the center swing the rotating swing revolving body of putting on gear and fixing with put on lower shaft gear that gear is meshed and by on two gear transmission rotatablely move, swing rotating lower shaft; It also has the bearing of the gear side rotation that periphery is fixed on the sewing machine frame, interior Zhou Zhicheng lower shaft, the periphery of this bearing, be formed cylindrical shape, rotate relative to sewing machine frame and adjust the backlash of putting on gear and lower shaft gear so that pass down the bearing of Spindle Status with respect to the axle center off-centre in interior week.
The lower shaft driving mechanism of above-mentioned Sewing machines can realize not having oiling, but when adjusting lower shaft gear and putting on gap between the gear by regulating eccentric structure, can make lower shaft that certain displacement takes place, yet lower shaft is to drive shuttle to rotate, can make shuttle also produce displacement thereupon, influence the precision of processing.
Summary of the invention
The purpose of this utility model is at the above-mentioned problems in the prior art, provides a kind of degree of regulation height, compact conformation and structural stability good Sewing machines lower shaft backlash regulator.
The purpose of this utility model can realize by following technical proposal: a kind of Sewing machines lower shaft backlash regulator, be arranged on the frame, comprise end and the joining sector gear of last axle, it is characterized in that, this device comprises that also being arranged in the sector teeth wheel sells, between gear pin and sector gear, be provided with bearing, described gear pin is connected with regulating part, described regulating part links to each other with frame and can do eccentric rotary by the driven gear pin when it rotates, between regulating part and frame, be provided with the retaining mechanism that both are fixed, and when described retaining mechanism unclamps, can rotate above-mentioned regulating part.
After Sewing machines uses a period of time, can produce backlash because wear and tear between sector gear and the lower shaft gear, unclamp the retaining mechanism in this device this moment, rotate regulating part, regulating part driven gear pin is done eccentric rotary, and promptly the sector gear that is connected with gear pin is also done eccentric rotary, and sector gear is near lower shaft gear, thereby adjusted the backlash between sector gear and the lower shaft gear, finished and tighten retaining mechanism more again after the adjustment and make regulating part be fixed in the frame place.
