Abstract
The invention relates to a feed lifting cam which is provided with a cam body. The cam is in a peach shape, a shaft hole is formed in the middle of the cam, a locating hole communicated with the shaft hole is formed in the top, and a limiting hole is formed above one end of the shaft hole. The feed lifting cam is simple in structure, fixation of a path is guaranteed through a peach-shaped profile of the cam, the feed lifting effect is good, and feeding is stably carried out.
Description
Technical field
The present invention relates to Sewing machines field, relate in particular to a kind of tooth lifting cam.
Background technology
In Sewing machines, in order to make sewing move forward, on Sewing machines table, be provided with feed dog device, feed dog device is by upper and lower and seesaw and realize the conveying of sewing.In order to make the feed dog can be up and down, on general Sewing machines, linkage is set and controls, but this complicated structure, and stabilizing effect is poor.
Summary of the invention
Technical problem to be solved by this invention is that a kind of tooth lifting cam of good stability 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 tooth lifting cam, there is cam body, and described cam is peach-shaped, in the middle of it, is provided with axis hole, and top is provided with the locating hole communicating with axis hole.
Preferably, top, described axis hole axis hole one end is provided with spacing hole.
Compared with prior art, usefulness of the present invention is: this tooth lifting cam is simple in structure, by its peach-shaped profile, guarantees the fixing of route, lifts tooth effective, and feeding is stable.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is tooth lifting cam end face structure schematic diagram of the present invention;
Fig. 2 is the structure cutaway view of A-A in Fig. 1.
In figure: 1, cam; 2, axis hole; 3, spacing hole; 4, locating hole.
the specific embodiment:
Below in conjunction with the drawings and the specific embodiments, describe the present invention:
Tooth lifting cam shown in Fig. 1 and Fig. 2, has cam 1 body, and described cam 1 is peach-shaped, in the middle of it, is provided with axis hole 2, and top is provided with the locating hole 4 communicating with axis hole 2, and described axis hole axis hole 2 tops, one end are provided with spacing hole 3.
During use, by axis hole 2, cam 1 is fixed on axle, then by bolt, connects locating hole 4 cam 1 and axle are fixed, during installation, by 3 pairs of cams of spacing hole, undertaken spacing.
This tooth lifting cam is simple in structure, by its peach-shaped profile, guarantees the fixing of route, lifts tooth effective, and feeding is stable.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
