Description

DETAILED DESCRIPTION OF THE INVENTION Purpose of the Invention (Field of Industrial Application) The present invention relates to a surface peeling tool for punching the surface of an object to be peeled to peel the surface. When tightening with nuts, the oxide film on the surface of the steel plate must be peeled off in order to prevent slippage between the bolts and nuts due to contact with the oxide film on the surface of the steel plate, or The present invention relates to a surface peeling tool used for peeling off letters and the like marked on an asphalt road surface for replacement.

(Prior art) Conventionally, as this type of surface peeling tool, three to four strips are mounted on a rotating body that is rotated around one axis, and extend parallel to the axis.
Two approximately rectangular peeling plates are swingably supported via a chain, and as the rotating body rotates, the surface of the object to be peeled is struck and peeled by a large number of teeth formed on the outer edge of the rotating body. It is known that it is composed of

(Problems to be Solved by the Invention) However, in this conventional configuration, the teeth formed on the outer edges of the three to four peeling plates sequentially contact the surface of the object to be peeled, and the object to be peeled is Since the surface of the device is designed to be peeled off, the teeth of the peeling plate are likely to wear out, and there is a problem in that the peeling plate must be replaced with a new one.

In addition, in this conventional surface peeling PJjg, a large number of teeth are arranged on a uniaxial line along the outer edge of the peeling plate so that they simultaneously contact the surface of the object to be peeled.
If the surface of the object to be peeled is uneven, there is a problem that all the teeth do not come into uniform contact with the surface and a partial gap is formed between them, making it impossible to perform the peeling operation smoothly. there were.

Structure of the Invention (Means for Solving the Problems) The present invention has been made by focusing on the above-mentioned problems. A plurality of support shafts 7 are supported on the rotating body 4 on the same circumference centered on the axis of the rotation body 4 and extend parallel to the axis. The peeling plate 1o is supported so as to be movable individually and relatively rotatably in parallel to orthogonal to the axis of 4, and has a plurality of peeling plates 1o having a large number of teeth 10a on the outer periphery.

(Function) Therefore, in the surface peeling tool of this invention (the rotating body 4
With the rotation of the rotating body 4, a large number of peeling plates 10 stacked and supported on a plurality of support shafts 7 are individually moved to the outside of the rotating body 4 by centrifugal force, and in this state, the rotating body 4 is attached to the object to be peeled 18. By approaching the surface of the object 18, a large number of peeling plates 10 on each support shaft γ come into contact with the surface of the object 18 separately at the tooth 108 portion on the outer periphery, and strike and peel the surface.

At this time, each peeling plate 10 is relatively rotated on the support shaft 7,
Since a large number of teeth 10a on the outer periphery are successively projected to the outside of the rotating body 4, the teeth 10a of the peeling plate 10 are not locally worn out, and the frequency of replacement of the peeling plate 10 can be reduced. In addition, since a large number of peeling plates 10 on the support shaft 7 can each move in a direction perpendicular to the support shaft 7, even if the surface of the object to be peeled 18 is uneven, each peeling plate 10 can move according to the uneven surface. The teeth 10a of each peeling plate 10 are evenly bonded to the uneven surface, and the peeling operation can be performed smoothly.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

In this surface peeling tool, a motor 1 is attached to one side of a frame 2 which houses a reduction gear groove therein. A threaded rod-shaped rotating shaft 3 is provided protruding from the other side of the frame 2,
As the motor 1 rotates, it is driven to rotate via a speed reduction mechanism. Note that 19 indicates a handle.

The rotating body 4 includes a pair of discs 4a, 4b and a side disc 4a,
It is formed almost in a spool shape by the shaft cylinder 4C between 4b,
It is screwed and fixed to the rotating shaft 3 in the shaft tube 4C. The four recesses 5 are formed on the inner surface of one circle k 4 a so as to be arranged at equal intervals on the same circumference centered on the rotational axis of the rotating body 4 . 4 through holes 6
are formed on the other disc 4b of the rotating body 4 so as to correspond to the recesses 5, respectively.

The four support shafts 7 are inserted through the through holes 6 into the recesses 5 and supported between the side disks 4a and 4b, and extend in parallel in the same direction as the rotational axis of the rotating body 4.A mounting plate 8 is multiple screws 9
It is fixed to the side surface of the rotating body 4, and the outer surface of the through hole 6 is closed to allow the support shaft 7 to be removed. Also, this mounting plate 8
can be easily removed from the rotating body 4 by loosening the screws 9, and in this removed state, the support shaft 7 can be pulled out laterally from the rotating body 4, and the peeling plate 10 can be replaced as described later. There is.

A large number of peeling plates 10 are formed by forming a large number of mountain-shaped teeth 10a on the outer periphery of a metal disk and forming a hollow hole 10b with a larger diameter than the support shaft 7 in the center, and rotate some of the teeth 10a. A plurality of spindles 7 are stacked one on top of the other so as to protrude outward from the disks 4a and 4b of the body 4, and each spindle 7 is inserted into the hole 10b.
It is supported by being inserted into. Therefore, each peeling plate 10 can be relatively rotated independently on the support shaft 7, and can also be moved independently in a direction perpendicular to the rotational axis of the rotating body 4, as shown in FIG. With the rotation of the rotating body 4, the centrifugal force causes each member to move outward from the rotating body 4.

The cover 11 is attached to the side surface of the frame 2 so as to cover the outside of the rotating body 4, and the teeth 10 of the peeling plate 10 are attached to the lower part of the cover 11.
A handle 12 is provided protruding from the upper surface of the cover 17, and has a lower opening 11a for protruding the handle 12 and a side opening 11b for replacing the array plate 10. This handle 12 and the handle 19 allow the entire surface peeling tool to be lifted and moved.

The adjusting body 13 is rotatably supported on the side surface of the cover 11 by a pin 14 at its base end so as to be located on one side of the lower opening 11a of the cover 11, and is secured by a screw 15 and a long nut 16 at its distal end. It is fixed to a long hole 17 on the cover 11 so that its position can be adjusted. And this regulator 1
3 has an arcuate portion 13a approximately in the center thereof that is in contact with the surface of the object to be peeled 18, and the tooth 10a of the peeling plate 10 is moved from the arcuate portion 13a based on the position adjustment of the adjustment body 12. It is now possible to change the protrusion type.

Next, the operation of the surface cutting tool constructed as described above will be explained.

Now, in this surface peeling tool, when the rotary body 4 is rotated with the rotation of the motor 1, a large number of peeling plates 10 stacked and supported on each spindle 7 are pushed outward of the rotary body 4 by centrifugal force. The disks 4 of the rotating body 4 are moved separately as shown in FIG.
It is placed in the most protruding state from a and 4b. In this state, as shown in FIGS. 1 and 2, the lower opening 11a of the cover 11 is opened.
When the arcuate portion 13a of the adjusting body 13 provided on one side is brought into contact with the surface of the object to be peeled 18, the teeth of the peeling plate 10 that revolve around the surface side of the object to be peeled 18 as the rotating body 4 rotates. 10
a sequentially collides with the surface of the object 18 to be peeled off.
At this time, when the surfaces of the peeling plates 1o are beaten and peeled off, each peeling plate 1o is relatively rotated on the support shaft 7, and the teeth 10a on the outer periphery successively protrude outward from the disks 4a, 4b of the rotating body 4. Therefore, 1! 121110a of the Il separation plate 10 will not be locally worn (and there is no need to replace the separation plate 10 frequently. Also, the large number of separation plates 10 on each support shaft 7 will not wear out locally in the area of the hole 1011). Since each of the peeling plates 10 can be moved individually in the direction orthogonal to the support shaft 7, even if the surface of the object to be peeled 18 is uneven, each peeling plate 10 can be moved to an arbitrary position according to the uneven surface. 10
m10a is uniformly bonded to the uneven surface. Therefore, the peeling work can be performed evenly and smoothly.

Note that the present invention is not limited to the configuration of the embodiment described above, and for example, adjustment (the book 13 is adjusted to the lower opening 1 of the cover 11).
The structure of each part may be arbitrarily changed without departing from the spirit of the present invention, such as by providing a pair of parts corresponding to each other on both sides of 1a and connecting them to a bean so that they can be rotated in one piece. It is also possible to do.

Effects of the Invention As detailed above, in this invention, the peeling operation is performed in a shared manner by a large number of teeth provided on the outer periphery of a large number of peeling plates.
It is possible to prevent local wear of the teeth and reduce the frequency of replacing the peeling plates, and a large number of peeling plates can be individually moved to arbitrary positions to match the uneven surface of the object to be peeled. , the teeth of each peeling plate are uniformly bonded to the uneven surface and the surface can be peeled off evenly.
