Abstract
The invention discloses a novel cam gear. The novel cam gear is characterized in comprising a transmission shaft sleeve pipe, a cam wheel body, a chain pole block ring, and through bolt holes arranged on the cam wheel body; the novel cam gear is arranged on the transmission shaft sleeve pipe; the centre of the novel cam gear and the centre of the transmission shaft sleeve pipe are asymmetrically arranged, so that when the novel cam gear rotates along with a main transmission shaft, a driving chain pole is driven to swing in a parabola manner by the novel cam gear in a certain track, and finally, upward and downward linear movement of a presser foot locking block along a machine head box vertical shaft is realized; one side of the cam wheel body is provided with the chain pole block ring; the six through bolt holes are arranged on the cam wheel body, and are used for fixing of a chain pole laterally toward a tightening pressing plate. The cam wheel body is symmetrically provided with two through holes so as to reduce self weight of the novel cam gear, weight of the novel cam gear is reduced, and vibration caused by cam rapid rotating is reduced.
Description
Technical field
The present invention relates to a kind of mechanical device, specifically refer to a kind of new type of cam device.
Background technology
Along with the extensive raising of head rotating speed, the rotating speed also necessary corresponding raising of its corresponding miscellaneous part, such as the most key head color changing device, the action each time of its thread take-up tension lever must adapt with the operating frequency of head shank.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of convenience, safety device, with the security of assurance device, comfortableness and reduce product cost, devise a kind of new type of cam device.
The present invention is achieved by following technical proposals:
A kind of new type of cam device, comprise on drive-shaft tunnel, cam wheel body, chain pole spacing circle and cam to wearing bolt hole, described cam gear is located on drive-shaft tunnel, it is characterized in that cam gear center and driving sleeve tube hub asymmetric.
As preferably, the side of described cam wheel body is provided with the back-up ring of chain bar, also has 6 bolts hole on cam wheel body simultaneously.
As preferably, described cam wheel body is symmetrical arranged two through holes.
Advantage of the present invention:
The present invention is novel in design, and when being connected with the drive chain bar of presser feet locating piece, firmness and stability very well, can ensure running up of high speed embroidery machine head color changing device.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the present invention is further detailed explanation.
Fig. 1 is a kind of new type of cam apparatus structure schematic diagram.
Detailed description of the invention
A kind of new type of cam device, comprise on drive-shaft tunnel, cam wheel body, chain pole spacing circle and cam to wearing bolt hole, described cam gear is located on drive-shaft tunnel, it is characterized in that cam gear center and driving sleeve tube hub asymmetric, the side of described cam wheel body is provided with the back-up ring of chain bar, also has 6 bolts hole on cam wheel body simultaneously.Cam wheel body two through holes 3 are symmetrical arranged, the vibration brought when can reduce installation weight and cam fast rotational.
