Abstract
The utility model relates to a wave sewing presser foot cloth feeding cam which comprises a disc base. A cam groove is formed in the disc base. A cam body is arranged on the inner side of the cam groove, wherein the cam body and the cam groove are the same in outline. A boss is arranged on the cam body. A circular installation hole is formed in the center of the boss. Guiding holes are formed in the cam body, and the number of the guiding holes is two. Threaded holes are formed in the lateral side of the cam body, and the number of the threaded holes is two. The wave sewing presser foot cloth feeding cam is simple in structure, continuous in cam edge and high in transition effect, therefore, stable work can be ensured, a connecting rod is not prone to disengaging, the service life is long, and the machining quality and the machining efficiency are ensured.
Description
Technical field
The utility model relates to the Sewing machines field, relates in particular to a kind of wave seam presser feet and send step cam.
Background technology
Along with constantly bringing forth new ideas of sewing machine technique, making that present Sewing machines can be different according to the client requires to make, and wave is made firmly and lines is clear attractive in appearance, is widely used in clothes and spins with family the field of making.Existing wave seam is mainly to realize the swing of eedle by designing cam, thereby completes the wave seam.But existing cam structure more complicated, difficulty of processing is high, and easily landing from the cam of connecting rod in process, affects working (machining) efficiency and quality.
Summary of the invention
Technical problem to be solved in the utility model is to provide the wave seam presser feet of a kind of working stability and long service life to send step cam.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of wave seam presser feet send step cam, comprise disc base, be provided with cam path in described disc base, the cam path inboard is provided with the cam identical with described cam groove profile, be provided with boss on cam, the boss center is provided with the circular mounting hole.
Preferably, be provided with pilot hole on described cam.
Preferably, described pilot hole has two.
Preferably, described boss side surfaces is provided with screwed hole.
Preferably, described screwed hole has two.
Compared with prior art, usefulness of the present utility model is: this wave seam presser feet send step cam simple in structure, and cam wheel limit is continuous, transition effect is high, therefore guarantee steady operation, and connecting rod is difficult for slippage, long service life guarantees crudy and efficient.
Description of drawings:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is that the utility model wave seam presser feet send the step cam structural representation.
In figure: 1, disc base; 2, cam; 3, boss; 4, cam path; 5, installing hole; 6, pilot hole; 7, screwed hole.
The specific embodiment:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of wave seam presser feet shown in Figure 1 send step cam, comprise disc base 1, be provided with cam path 4 in described disc base 1, cam path 4 inboards are provided with the cam 2 identical with described cam path 4 profiles, be provided with boss 3 on cam 2, boss 3 centers are provided with circular mounting hole 5; For the ease of installing, be provided with two pilot holes 6 on described cam 2; For the ease of sending step cam and connecting rod to fix, described boss 3 sides are provided with two screwed holes 7.
This wave seam presser feet send step cam simple in structure, and cam wheel limit is continuous, and transition effect is high, therefore guarantees steady operation, and connecting rod is difficult for slippage, long service life, assurance crudy and efficient.
It is emphasized that: above is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
