1. Field of the Invention
This invention relates to an improved cinquefoil chuck and particularly to a chuck provided with a plurality of clamping jaws that close to clip goods and miscellaneous articles or release to place them.
2. Description of Related Art
In industrial circles, there are usually scattered articles and goods that must be handled, arranged, classified, placed, and stocked for management, so a cinquefoil chuck must be used to clamp, for example, worksite wastes, trash, recycled and classified parts for environmental protection, scattered articles in a workshop, and the like.
The cinquefoil chuck mainly comprises a clamping jaw mechanism provided with a plurality of clamping jaws that may release and close. The clamping jaws are connected to and driven by a driving mechanism to release and close. The plurality of clamping jaws look like petals of a plum flower, so the chuck is named cinquefoil chuck. Issues caused by a conventional cinquefoil chuck are described below.
The cinquefoil chuck is generally operated in a site where articles are piled. Gap lie between the clamping jaws, so the articles that are in the gaps cannot be clamped and then must be moved a little bit by an operation machine or chassis provided with the clamping jaws. However, if the operation machine or chassis is moved, an enough space in the workshop is a must. The work environment is generally too narrow to move, or when moving, the machine or chassis dangerously hit a person or article nearby.
Further, the conventional cinquefoil chuck is generally used to clamp the article. If the article to be clamped is too fluffy and occupies more space, the article must be squeezed and then clamped. Thus, man hour waste and inconvenience are caused. The conventional cinquefoil chuck in a weight is usually hanged in the air and is not provided with a structure and function that may squeeze a specific article at a specified angle.
Consequently, because of the technical defects of described above, the applicant keeps on carving unflaggingly through wholehearted experience and research to develop the present invention, which can effectively improve the defects described above.
In consideration of the mentioned-above defects of prior art, this inventor considers to make improvement. In order to improve the defect in the prior art, a cinquefoil chuck is provided in this invention, comprising a clamping jaw mechanism provided with a plurality of clamping jaws that may release and close. The clamping jaws are connected to and driven by a driving mechanism to release and close, being characterized in that the clamping jaw mechanism is connected to and driven by an autorotation mechanism to rotate. Along with the autorotation mechanism that rotates, the cinquefoil chuck may rotate at an angle and capture a wanted article at a tuned angle of direction for safe and easy operation.
Besides, in this invention, an angle control part mat be connected to the top of chuck. The angle control part comprises an H-shaped clamping arm. The H-shaped clamping arm pivots a first vertical rod and a second vertical rod from two ends of a horizontal rod. The first vertical rod comprises an upper section pivoted to a lower section and serves as a section of flexible rod. A lower extreme of the lower section and a lower extreme of the second vertical rod are separately pivoted to the chuck. With the upper section that is flexible, an angle of bend between the upper section and the lower section, an included angle between the second vertical rod and the horizontal rod, and a deflection angle of the chuck may be changed.
The chuck in a specified weight at the adjustable angle may serves as a workpiece that is driven to squeeze the article. For example, the upper section serving as the section of flexible rod may be used to squeeze a metallic case, a can, a reinforcing steel, a sheet bar, a pasteboard box, a cardboard box and the like as the fluffy article.
Now, the present invention will be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.
With reference to
Further, in an embodiment, the autorotation mechanism (13) according to this invention may comprise a top mount (130) provided with an engine mechanism (131) that may be a motor supplying the power of operation, where a shaft (132) stretches; a passive ring (133) connected to the top of clamping jaw mechanism (11), in which a plurality of alternate teeth (134) are formed at an internal marginal zone of the passive ring (133) and a top tray (135) is provided on a top face of the passive ring (133) and provided with a thru hole (136) having a cover plate (137) provided with a thru hole (138) through which the shaft (132) passes; and a driving mechanism (14) that may be a gear connected to and driven by the shaft (132) of the engine mechanism (131), in which each tooth (141) of the gear engages the tooth (134) of the passive ring (133) to impede the passive ring (133) from running, as shown in
With reference to
While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
