Abstract

The invention 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 a same circle center, wherein a fixing hole (3) is arranged on the second cam (2); a through hole (4) is arranged on the first cam (1) and the second cam (2); the through hole (4) penetrates through the first cam (1) and the second cam (2); and 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 structure design; the eccentric cam is firmer; the eccentric cam is more compactly mounted with equipment; and the fault generated during the running process of the industrial sewing machine is reduced.

Description

A kind of eccentric cam that is used for industrial sewing machine

Technical field

The present invention relates to a kind of eccentric cam that is used for industrial sewing machine, belong 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, its reason be since eccentric cam install not tight, thereby produce fault when causing the industrial sewing machine operation.

Summary of the invention

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

Major technique of the present invention thes contents are as follows: a kind of eccentric cam that is used for industrial sewing machine; Comprise first cam (1), second cam (2); Said first cam (1), second cam (2) are positioned at same circle centre position; Fixing hole (3) is set on said second cam (2); On first cam (1) and second cam (2), through hole (4) is set, said through hole (4) is through first cam (1) and second cam (2), and the center of circle of said through hole (4) is different with the common center of circle of first cam (1), second cam (2).

By technique scheme, the present invention has advantage at least: reasonable in design of the present invention, eccentric cam is more firm, and it is tightr to make eccentric cam and equipment install, the fault that has produced when having reduced the industrial sewing machine operation.

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

Description of drawings

Fig. 1 is a front view of the present invention;

Fig. 2 is a left view of the present invention;

Fig. 3 is a right view of the present invention.

The specific embodiment

Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, to its specific embodiment, structure, characteristic and the effect thereof that proposes according to the present invention, specify as after.

Like Fig. 1, Fig. 2, shown in Figure 3; A kind of eccentric cam that is used for industrial sewing machine comprises first cam 1, second cam 2, and said first cam 1, second cam 2 are positioned at same circle centre position; On said second cam 2 fixing hole 3 is set; On first cam 1 and second cam 2, through hole 4 is set, said through hole 4 is through first cam 1 and second cam 2, and the center of circle of said through hole 4 is different with the common center of circle of first cam 1, second cam 2.

The above only is preferred embodiment of the present invention, is not the present invention is done any pro forma restriction; Though the present invention discloses as above with preferred embodiment; Yet be not in order to limiting the present invention, anyly be familiar with the professional and technical personnel, in not breaking away from technical scheme scope of the present invention; When the technology contents of above-mentioned announcement capable of using is made a little change or is modified to the equivalent embodiment of equivalent variations; In every case be the content that does not break away from technical scheme of the present invention, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical scheme of the present invention according to technical spirit of the present invention.

Claims

1. eccentric cam that is used for industrial sewing machine; It is characterized in that: comprise first cam (1), second cam (2); Said first cam (1), second cam (2) are positioned at same circle centre position; Fixing hole (3) is set on said second cam (2); On first cam (1) and second cam (2), through hole (4) is set, said through hole (4) is through first cam (1) and second cam (2), and the center of circle of said through hole (4) is different with the common center of circle of first cam (1), second cam (2).
