DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vibratory working machine that performs various operations such as rust hammering and rivet caulking using tool vibration.

Traditionally, with the bamboo digging tool that performs the valley work by motion,
Workers often wait and work directly with their hands. (L) 1. When a worker holds this good tool in his straight hand, the -t vibration will cause Raynaud's liver disease (white wax disease) in the workplace, causing an occupational health problem. We are raising
00 For example, pneumatic vibrating tools such as hand-type air hammers and jet f-zels are used for rust removal work on structures on the deck of ships, but since the work range is wide, it takes a long time. As a result, Raynaud's syndrome (・) and independence have become a major problem.

The purpose of the present invention is to prevent workers from being affected by vibrations! 6. To provide a vibrating working machine that does not give any decorative apricots.

Therefore, in the present invention, the base end 1M+1 of the support arm with the vibrating tool attached to the tip is supported on the base so as to be rotatable in the direction of vibration of the vibrating tool, thereby reducing the vibration of the vibrating tool by rotating the support arm. The aim is to achieve the above objective by replacing and removing the

EMBODIMENT OF THE INVENTION Hereinafter, an embodiment in which the present invention is applied to a rusted rock will be described based on the drawings.

@Figures 1 and 2 show the first and worst examples of the present invention. 10 in the same figure, the base 1 is provided with a flexible wheel 2 on the front of one side, fixed wheels 3 on both sides of the rear, and a short cylindrical retaining ring 4 in the center. Fixed horizontally and integrally. The retaining ring 4 is provided with a shaft insertion hole 5 on both side walls and a support member 6 on the outer surface of the upper wall, and has a supporting shaft rotatably inserted into the shaft insertion hole 5 inside. A short cylindrical rotating ring 8 is supported via a bolt 7 so as to be rotatable in the vertical direction. The rotating ring 8 is formed with a female thread 9 on both sides of which the bolt 7 is screwed, and the base 1lii111I of the pipe-shaped support arm 10 is inserted into the inside of the rotating ring 8 and is held by the bolt 7 on the front side. ing.

A hose (not shown) for supplying compressed air into the support arm 10 is connected to the base layer of the support arm 10, and a hose (not shown) serving as a vibrating tool is connected to the tip of the support arm 10.
However, a weight mount 12 is attached slightly in front of the 7. The air hammer 11 is used to remove rust spots generated on the surface to be worked due to vibration. When compressed air is supplied through the support arm 10, the air hammer 16 crimped to the surface to be worked is removed by -L. It is designed to vibrate back and forth in the vertical direction. Further, the weight mounting base 12 has a weight mounting threaded rod 13 vertically protruding from the center of its upper surface.
At 3, a peg 14 with a predetermined amount of electricity is selectively attached by a nut 15 for crimping the nozzle 16 of the air nozzle 11 onto the surface to be worked.

The support member 6 also has a spring locking plate 21 protruding forward on its siJ edge, and a retaining part 23 having an arcuate upper rear half and a shaft insertion hole 22 in the center. have. A connecting rod 24 is connected to the retaining portion 23 by a bolt 25 and a nut 26 so as to be freely movable rearward. A slit 27 that engages with the retainer s23 and an insertion hole 28 through which the bolt 25 is inserted are formed in the lower part of the connecting rod 24 so as to be perpendicular to each other. The sling 27 is formed at such a depth that its inner bottom surface comes into contact with the front half of the upper end of the retaining portion 23 when the connecting rod 24 is vertically attached to the engagement f123.

Further, on the upper part of the connecting rod 24, a striped ring locking piece 29 is provided on the front end 11il, a suppressor 30 is provided on the rear side, and a threaded portion 31 is provided on the upper end. One end of the spring 32 is locked to the spring locking plate 21, and the other end of the spring 32 is locked to the spring locking piece 29 in item 11I. As a result, the connecting rod 24 has an inner bottom surface of the sulin 27 that is connected to the engaging portion 2.
It is held in an upright state in contact with the front half of the upper end of 3.

Further, the pressing body 30 includes a pressing piece 3 twisted at right angles to the rear layer.
0A, and when the connecting rod 24 is rotated backward, the pressing piece 30A pushes down the base end side of the support arm 10, and the air hammer 11 at the tip of the support arm 10 is pressed against the work surface. It is caused to retreat upward against the enemy.

On the helmet, f411 g pin screw part 31 is operated...7 dollars 3
3 are screwed together and there are 10. The operating handle 33 is composed of a support rod 34 having a dowel connected to the threaded portion 31, and a handle rod 35 fixed to the support rod 34 at right angles thereto. On both ends of the handle rod 35, there are handle rods 35.
．． An elastic member 36, such as a vinyl hose, is coated to absorb the captured motion transmitted by E.

Next, the operation of this embodiment will be explained. First, in the rust hammering work, the pressure force of the air hammer 11 in the direction of the work is determined by the number of weights 14 attached to the weight mounting base 12.
Arrange. Incidentally, in this case, by preparing a plurality of weights 14 with different electric power in advance, the air hammer 1
The pressure bonding force of step 1 can be finely adjusted. When compressed air is supplied into the support arm 10, the air pumps 16 of the air pumps 11 move back and forth up and down, thereby removing rust that has occurred on the workpiece (3). At this time, the bolt 7 is attached to the base end side of the support arm 10 or to the retaining ring 4.
Since the air hammer 11 is rotatably supported in the vertical direction, when the hammer 16 of the air hammer 11 is rotated vertically, the support arm 10 rotates in the vertical direction, and as a result, the vibration of the air hammer 11 is reduced to the support arm 10. It is converted into a rotational motion and buffered, and the taste is muted. Here, the remaining vibrations that have not been removed are transmitted to the gripping rod 35 of the operating handle 33 via the connecting rod 24, but since the gripping rod 35 is covered with the elastic member 36, the vibrations are absorbed by the elastic member 36. It will not be given to anyone.

10,000, when the operating handle 33'' is tilted backwards using the bolt 25 as a fulcrum, the suppressing body 30 of the connecting rod 24
Push the proximal side of the support arm 1 downward.
0 is rotated about the bolt 7 as a fulcrum, and the air nozzle 11 at the tip thereof is displaced upwardly with respect to the work surface. Therefore, in this state, the base 1 can be moved to any work surface. here,
After moving the base 1, when you release your hand from the operating handle 33, the operating handle 33 is returned to the upright state by the spring 32 116, and the proximal end of the support arm 10 is pushed downwards. The suppressor 30 rotates upward.
As a result, the air hammer 11 of the support arm 10 is pressed against the workpiece, and the rust hammering work is again viewed from a new perspective. In this way, the rust hammering work is performed while moving the base 1 to an arbitrary position.

+In the example, the retaining ring 4 is fixed to the base 1 L2
．． A rotary ring 8 is provided inside the retaining ring 4 of 1- through a bolt 7 so as to be rotatable in the upward F direction. Since the end side was held, the soil vibration of the air pump 11 was converted into rotational movement of the support arm and buffered.

The vibrations that are not removed and transmitted to the operation handle 33 are completely absorbed by the elastic member 36 that covers the part where the operator digs, so even if the operator uses the machine continuously for a long time, the operation will be easier. This can prevent people from developing Raynaud's syndrome. Moreover, since the air hammer 11 is configured to be attached to the tip of the support arm 10, if the length of the support arm 10 is made long, the operation handle 3
The worker located at position 3 can be separated from the air hammer 11, so the worker can work safely without the risk of injury from flying iron pieces during rust-stripping, and can work in a standing position. I can do it.

In addition, a weight mount 12 is provided near the air hammer 11 of the support arm 10, and the weight 14 can be selectively attached to the plow mount 12. The pressing force of the air hammer 11 against the surface to be worked can be adjusted by selecting the overlapping position of the hammers 14.

Historically, wheels 2 and 3 were installed on the bottom of the base 1, so the base 1
can be moved to any position with light force. At this time, when the operating handle 33 is tilted backward, the support arm 10
is NLIJJ, and the machine r-h/711 at its tip retracts upwards from the surface to be worked, so that when moving the base 1, the air machine 11 can be easily moved without becoming an obstacle.
4# can be made.
