Description
Technical field
The present invention relates to the Sewing machines field, relate in particular to a kind of needle bar drive device.
Background technology
Sewing machines has been spun manufacture field by clothes and family always since invention favors.Along with the continuous progress of science and technology, existing sewing machine is of a great variety, can make various circuits.And make mainly is that eedle by being installed on the shank is realized making; And the motion of eedle mainly is to realize the power transmission by the gangbar that is connected with shank.In order to realize that shank moves up and down, existing sewing machine mostly in the gangbar end by the fixedly connected overhead cam of crank mechanism, mostly be fixed between existing cam mechanism and the gangbar, therefore mount and dismount cumbersome, and maintenance cost height.
Summary of the invention
Inventing technical problem to be solved is, a kind of needle bar drive device of being convenient to mount and dismount is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of needle bar drive device, comprise axle, described shaft end is provided with cam, cam is provided with cam path, the top of axle is provided with gangbar, and described gangbar head is provided with the shank that is used to install eedle, and the gangbar end is installed in the cam cam path.
Preferably, described gangbar end between cam path for being slidingly connected.
Compared with prior art, usefulness of the present invention is: this needle bar drive device transmission is effective, is convenient to installing/dismounting and maintenance, and its maintenance cost is also lower, and is stable, and long service life has guaranteed the crudy of product.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a kind of needle bar drive device structural representation of the present invention.
Among the figure: 1, cam; 2, gangbar; 3, axle; 4, shank; 5, cam path.
The specific embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of needle bar drive device shown in Figure 1 comprises axle 3, and described axle 3 ends are provided with cam 1, cam 1 is provided with cam path 5, the top of axle 3 is provided with gangbar 2, and described gangbar 2 heads are provided with the shank 4 that is used to install eedle, and gangbar 2 ends are installed in cam 1 cam path 5; Stable in order to guarantee gangbar 2, described gangbar 2 ends between cam path 5 for being slidingly connected.
This needle bar drive device transmission is effective, is convenient to installing/dismounting and maintenance, and its maintenance cost is also lower, and is stable, and long service life has guaranteed the crudy of product.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
