Abstract

The utility model relates to an eccentric cam for an industrial sewing machine and belongs to the field of machinery. The eccentric cam comprises a first cam (1) and a second cam (2) which are located at the same circle center. The second cam (2) is provided with a fixing hole (3). A through hole (4) is formed in the first cam (1) and the second cam (2) and penetrates through the first cam (1) and the second cam (2). The circle center of the through hole (4) is different from the common circle center of the first cam (1) and the second cam (2). The eccentric cam for the industrial sewing machine is reasonable in structural design, firmer, and more compact in installation with equipment, and reduces failures during running of the industrial sewing machine.

Description

A kind of eccentric cam for industrial sewing machine

Technical field

The utility model relates to a kind of eccentric cam for industrial sewing machine, belongs to mechanical field.

Background technology

At present, eccentric cam of the prior art can break down when the production of industrial sewing machine because structural design is unreasonable, and its reason is because the eccentric cam installation is not tight, thereby produces fault when causing the industrial sewing machine operation.

The utility model content

For above deficiency, the utility model provides a kind of eccentric cam that is used for industrial sewing machine of new structure.

Main technical content of the present utility model is as follows: a kind of eccentric cam for industrial sewing machine, comprise the first cam (1), the second cam (2), described the first cam (1), the second cam (2) are positioned at same circle centre position, fixing hole (3) is set on described the second cam (2), at the first cam (1) and the second cam (2) through hole (4) is set, described through hole (4) is through the first cam (1) and the second cam (2), and the center of circle of described through hole (4) is different from the common center of circle of the first cam (1), the second cam (2).

By technique scheme, the utility model has following advantages at least: the utility model reasonable in design, and eccentric cam is more firm, and so that eccentric cam and equipment installation are tightr, the fault that has produced when having reduced the industrial sewing machine operation.

The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Description of drawings

Fig. 1 is front view of the present utility model;

Fig. 2 is left view of the present utility model;

Fig. 3 is right view of the present utility model.
