Abstract

PURPOSE:To improve the peeling capacity of a surface peeling device by providing two separate rotary disks in stead of a single disk, thereby making the rotary disks intimately about against a peeled surface. CONSTITUTION:A driving gear 2 is mounted on the drive shaft of a motor housed in a casing-like holder 1. An intermediate gear 3 is pivotally mounted on the left hand of the holder 1 as viewed in the accompanying drawing so as to be rotated by the driving gear 2. A pair of driven gears 5a and 5b are mounted on rotary shafts 6a and 6b so as to be rotated by the intermediate gear 3. Rotary disks 7 and 7 are detachably mounted to the rotary shafts 6a and 6b with female screws 9 and 9 of the disks 7 and 7 engaging male screws 8 and 8 of the shafts 6a and 6b, respectively. Peeling members 7a-7a made of diamond or super alloy steel are planted to the lower surfaces of the rotary disks 7 and 7.

Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to a surface stripping tool for hard materials, and is a surface stripping tool for stripping the surface of hard materials such as metals.

(Prior Art) For example, in a heavy steel frame building, an oxide film on the surface of a bolted joint portion of a steel frame is required to be peeled off in order to increase the coefficient of friction. Traditionally, this work was done using a single disc sander, etc.
The work was hard labor and inefficient.

(Problems to be Solved by the Invention) An object of the present invention is to provide a double-head type surface stripping tool in order to perform surface stripping work of oxide films and the like more efficiently with less effort.

Structure of the Invention (Means for Solving the Problems) The gist of the invention configured to solve the above problems is that the left and right parts of the holder tip 1a are provided with an intermediate gear 3 driven by a drive gear 2. 4a and 4b are rotatably equipped with rotary gears 5a and 5b for peeling, and furthermore, these rotary gears 5a and 5b are respectively interlocked with the intermediate gear 3, and rotation shafts 68 and 61 of the rotary gears 5a and 5b are provided. ) is configured such that a rotating disc 7 for peeling is removably screwed onto the threaded portion 8 at the lower end.

(Function) Since the present invention is configured based on the above-mentioned gist, the peeling action on the surface to be peeled is doubled by the double-head rotary disk 7 separated on the left and right sides, unlike the conventional case with only a single head. In addition to this feature, since the rotary disk 7 is separated into left and right sides, it has the effect of improving contact with the surface to be peeled.

(Example) Hereinafter, an example embodying the present invention will be described based on the drawings. The surface peeling tool 10 of this embodiment is constructed as a handy type, and a drive gear 2 is rotatably mounted on the drive shaft of an electric motor (not shown) housed in a case-like holder 1.

The intermediate gear 3 is rotatably supported by a shaft on the left side of the holder 1 in the drawing, and is rotatably interlocked with the drive gear 2.

The left and right driven gears 5a and 5b are located at the left end 1 of the holder 1 in the illustration.
The rotation shafts 6a and 5b are respectively attached to the left and right parts 4a and 4b of a.
It is rotatably supported via a shaft. And both rotating shafts 6a,
A threaded portion 8 is provided at the lower end of 6b, into which a threaded hole 9.9 of the rotary disk 7.7 is removably screwed.

The lower surfaces of the left and right rotating disks 7.7 mentioned above are grafted with peelable bodies 7a to 7a made of superalloy steel or diamond.The condition of the grafting is not limited, but it is preferable to match the material to be peeled. .

For this reason, unlike the conventional single-head type, the rotating disk 7.7 is a double-head type with separate left and right sides, and in addition to the feature of doubling the peeling action on the surface to be peeled, the rotating disk 7.7 is separated into the left and right sides. As a result, the contact property with respect to the surface to be peeled is excellent, and as a result, the peeling ability can be improved.

Effects of the Invention Ren's invention is based on the structure described in the claims, and with its structure, it achieves the above-mentioned effects, that is, a double-head type rotating disk separated on the left and right sides, which is different from the conventional single-head type. In addition to the feature that the peeling effect on the surface to be peeled is doubled, since the rotating disk is separated into left and right sides, it is excellent in contact with the surface to be peeled.
