The rivet is unqualified after riveting, is influenced by factors such as operating space and human misoperation when being decomposed, is easy to cause the fault of drilling and damaging products, and is very necessary to use a protective tool when being decomposed.

SUMMERY OF THE UTILITY MODEL

In view of the above problems, the utility model aims to provide a rivet painting and decomposition protection device, which solves the technical problems that the painting quality is low, the efficiency is low and the rivet is easy to drill and damage the product when painting the rivet.

In order to achieve the purpose, the utility model provides the following technical scheme:

a rivet painting and breakdown prevention apparatus, the apparatus comprising: a guard plate set, a shaft 3 and a lock nut 4;

the protection plate group comprises a plurality of protection plates 1, one ends of the protection plates 1 are connected through a shaft 3, and a locking nut 4 is arranged on the shaft 3;

the other end of each protection plate 1 is provided with a nail sleeve with different hole diameters.

The technical scheme of the utility model has the characteristics and further improvements that:

(1) the other end of each protection plate 1 is provided with a nail sleeve with a 120-degree socket.

(2) Each protection plate 1 is of a flat plate type structure, and the periphery of the protection plate is chamfered.

(3) The device further comprises: and the spring 2 is arranged between the shaft 3 and the protection plate group, and the lower end of the spring 2 is in contact with the locking nut 4.

(4) And replacing the protection plates of the nail sleeves with different corresponding hole diameters according to the sizes of the nail caps of the rivets to be painted and decomposed.

(5) When changing the guard plate that has different aperture nail covers, clockwise turning upwards pushes away lock nut 4 locking guard plate 1, when needing to change guard plate 1 again, counter-clockwise turning lock nut 4, under the effect of spring 2, is popped out rapidly after lock nut 4 breaks away from the screw thread, guarantees 1 quick replacement of guard plate, changes the back clockwise turning and upwards pushes away lock nut 4 and accomplishes guard plate 1 and change.

Compared with the prior art, the utility model has the following beneficial effects:

the utility model provides a novel rivet painting and disassembling protection tool, namely a rivet protection bent handle. The rivet protection bent handle can select the protection plate embedded with the nail sleeves of different specifications to perform rivet painting and decomposition operation according to rivets of different specifications, solves the problems that the rivet painting quality is low, the efficiency is low, products are easily damaged by drilling in the rivet decomposition process, and the like, and improves the appearance quality of an airplane.

The rivet protection bent handle has the characteristics of lightness and convenience in use, and the efficiency of the whole rivet painting process flow can be improved by 50% by using the rivet protection bent handle in the rivet painting process; the rivet disassembling device can effectively prevent quality accidents of drilling damage products from happening in the rivet disassembling process. The utility model can be popularized to the whole riveting industry.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention; the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; furthermore, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, as they may be fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The embodiment of the utility model provides a rivet painting and disassembling protection device, wherein a rivet painting and disassembling protection bent handle comprises a protection plate (1), a spring (2), a shaft (3) and a locking nut (4) as shown in figures 1 to 3; protection plate (1) is flat structure, peripheral chamfer, the nail cover of 120 nests in protection plate upper band, protection plate (1) has a plurality ofly, the nail cover of different apertures in every protection plate upper band is 1, protection plate (1) is connected through axle (3), epaxial lock nut (4) that have, according to the nail cap size through axle (3) change protection plate (1) that have different apertures nail cover, clockwise rotation pushes up lock nut (4) locking protection plate (1), when needing to change protection plate (1) again, counter-clockwise rotation lock nut (4), under the effect of spring (2), lock nut (4) are popped out rapidly after breaking away from the screw thread, guarantee protection plate (1) quick replacement, change back clockwise rotation and upwards push up lock nut (4) and accomplish protection plate (1) and change.
