Abstract
The utility model discloses a sewing machine work feed gauge needle adjustment mechanism, including work feed connecting rod outer lane, gauge needle cam inner circle, steel ball, holder, eccentric wheel subassembly, gauge needle adjusting part. Be processed into circular arc type raceway on the big connecting rod inner wall of work feed connecting rod outer lane, be processed into circular arc type raceway on the excircle of gauge needle cam inner circle, being equipped with the steel ball between the raceway of the raceway of work feed connecting rod outer lane and gauge needle cam inner circle, paring the steel ball with the holder, make up into one set of deep groove ball bearing subassembly with work feed connecting rod outer lane and gauge needle cam inner circle, steel ball, holder, its beneficial effect is: because integration deep groove ball bearing design, it replaces that it rubs to slide examines to rub with rolling to examine, has reduced the noise of bearing, has reduced the energy consumption, has improved the combination precision of subassembly, is convenient for install. Be fit for not having oil, the use of high -speed occasion, lengthened the life of machine.
Description
Technical field
The utility model relates to Sewing machines field, particularly relates to a kind of at a high speed without oily sewing machine cloth feeding needle gage governor motion.
Background technology
Existing sewing machine cloth feeding needle gage governor motion, what adopt is work feed connecting rod, needle gage cam, needle bearing, eccentric wheel assembly, needle gage adjusting part independently design, wherein needle bearing to be installed between work feed connecting rod and needle gage cam on roller surface, due to each part independent design, difficulty of processing is comparatively large, often needs apolegamy to reach anticipate accuracy; Be linear contact lay between needle roller and roller surface in addition, rubbing, it is comparatively large to examine coefficient, is easy to heating, affects the service life of machine.
Therefore, the present inventor makes further research this, and develop a kind of sewing machine cloth feeding needle gage governor motion, this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of sewing machine cloth feeding needle gage governor motion, eliminate the shortcomings such as needle bearing and work feed connecting rod, needle gage cam three coordinate difficulty, heating, noise large, add intensity and the precision of assembly, extend the service life of assembly.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of sewing machine cloth feeding needle gage governor motion, comprises work feed connecting rod outer ring, needle gage cam inner ring, the inwall of described work feed connecting rod outer ring is processed with circular arc type raceway, the cylindrical of described needle gage cam inner ring is processed into circular arc type raceway.
Further, be provided with steel ball between the raceway of the raceway in described work feed connecting rod outer ring and described needle gage cam inner ring, separate with retainer between described steel ball.
Further, also comprise needle gage adjusting part and eccentric wheel assembly, described needle gage adjusting part is arranged on needle gage cam inner ring by slide block or stripe shape notch, and described eccentric wheel assembly is arranged in the endoporus of needle gage cam inner ring.
Further, the aperture of described needle gage cam inner ring is provided with strip notch, for inlaying spring leaf, regulates the eccentric wheel assembly be arranged in endoporus.
After adopting such scheme, the utility model compared with prior art, has the following advantages:
Due to integrated deep groove ball bearing design, rubbing to examine with rolling replaces slip to rub and examine, and reduces the noise of bearing, reduces energy consumption, improve the combination precision of assembly, be convenient to install.Be adapted at using without oil, high speed situation, extend the service life of machine.
Accompanying drawing explanation
Fig. 1 is explosive view of the present utility model;
Work feed connecting rod outer ring 1, needle gage cam inner ring 2, steel ball 3, retainer 4,
Needle gage adjusting part 5, eccentric wheel assembly 6, slide block 7.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in the figure, a kind of sewing machine cloth feeding needle gage governor motion, the circular arc type roller surface of work feed connecting rod outer ring 1 and needle gage cam inner ring 2 is distributed with steel ball 3, by retainer 4, it is evenly separated, form integral type deep groove ball bearing assembly, needle gage adjusting part 5 is arranged on needle gage cam inner ring 2 by slide block 7, eccentric wheel assembly 6 is arranged in the endoporus of needle gage cam inner ring 2, the aperture of needle gage cam inner ring 2 is provided with strip notch, for inlaying spring leaf, the eccentric wheel assembly 6 be arranged in endoporus can be regulated.
Above are only specific embodiment of the utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
