Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic cleaning device that automatically brushes and cleans the insides of pipes and perforations formed in various blocks.

[Prior art and its problems]

In various metal pipes and in perforations formed in bulk metal materials such as cylinder blocks and differential blocks used in automobile parts, burrs may remain from thread cutting during manufacturing, or cast burrs may occur. To prevent this, the inside of the hole is cleaned using a wire brush, a brush containing abrasive grains, etc.

However, the reality is that this cleaning work relies exclusively on manual labor, which poses the problem of extremely low productivity.

The reason why cleaning inside pipes and holes in cylinder blocks etc. is not mechanized is because pipe diameters and hole diameters vary depending on the type, and some pipes in particular have unusual curved shapes such as bends. This is because there are also tubes.

For this reason, although the work of spraying high-pressure showers to clean the insides of pipes and the perforations of various blocks has been automated, the work of brushing and cleaning the insides of the holes has not yet been automated.

However, for items that are mass-produced based on certain standards, such as pipe members and cylinder blocks used as part of automobile parts, it is not profitable enough to mechanize the cleaning work inside the holes using brushes. It is thought that it will fit.

[Means for solving problems]

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic cleaning device that can automatically brush and clean the inside of pipes and perforations of blocks that are mass-produced according to certain standards using a simple mechanism.

To achieve this objective, the present invention is an automatic cleaning device that inserts a brush into a hole in a workpiece positioned at a fixed position and rotates it.The brush is attached to the tip and a motor is connected to the rear end to drive the brush. A rotary shaft is rotatably inserted into and supported by the cylindrical body, and the cylindrical body is connected to a cylinder and driven to insert and remove the brush into the hole of the workpiece, and the cylindrical body A work holding member that is pressed against the work when the brush is inserted into the hole of the work is attached to the tip side of the rotary shaft via a spring that can be expanded and contracted in the axial direction of the rotating shaft. shall be.

[Effect]

According to the present invention, when the workpiece is positioned at a fixed position, the cylindrical body connected to the cylinder is driven to move the brush at the tip of the rotary shaft inserted and supported into the cylindrical body into the hole of the workpiece. Let it be inserted.

At this time, the work holding member attached to the tip side of the cylindrical body is pressed against the work and is strongly pressed by the elasticity of the spring, so that the work is securely fixed by the work holding member.

In this state, the motor is operated to rotate the rotary shaft, and the brush at the tip of the rotary shaft is rotated within the hole of the workpiece to brush the inside of the hole.

When the inside of the hole has been cleaned in this manner, the motor is first stopped, and then the cylindrical body is driven to extract the brush attached to the tip of the rotating shaft from the inside of the hole of the workpiece.

At the same time, the workpiece holding member that had been pressed against the workpiece separates from the workpiece and its holding is automatically released.

〔Example〕

Hereinafter, embodiments of the present invention will be specifically described based on the drawings.

FIG. 1 is a front view showing an example of an automatic cleaning device according to the present invention, and FIG. 2 is an enlarged view of main parts showing its operation.

In this example, a brush 1 is attached to the tip,
A rotary shaft 3 connected to a motor 2 at the rear end and driven to rotate is inserted into a cylindrical body 4 made of a metal pipe or the like, and is driven by bearings 5 and 6 provided at both ends of the cylindrical body 4. It is rotatably supported.

The cylindrical body 4 is a workpiece W positioned at a fixed position.
It is arranged so as to vertically penetrate a base 7 provided directly above the base 7, and is held movably up and down by a plurality of guide rollers 8, 8, etc. disposed on the base 7. It is connected via a bracket 11 to a piston rod 10 of a cylinder 9 erected on a base 7 parallel to the cylindrical body 4, and the brush 1 is inserted into and removed from a hole 12 of a workpiece W by the cylinder 9. Driven.

Further, on the tip side of the cylindrical body 4, a work holding member 13 that is pressed against the work W when the brush 1 is inserted into the hole 12 of the work W is a spring that can be expanded and contracted in the axial direction of the rotary shaft 3. It is attached via 14.

The work holding member 13 is formed into a cylindrical body with an open lower end surface, with the rotary shaft 3 protruding from the tip of the cylindrical body 4 passing through a lid 15 that closes the upper end surface, and the lid 15 is normally extended. The brush 1 is supported by a spring 14 at a position where it abuts against a stopper 16 provided at the tip of the rotating shaft 3, and the brush 1 is accommodated therein.

The above is an example of the configuration of the automatic cleaning device according to the present invention, and the operation thereof will be explained next.

First, the piston rod 10 of the cylinder 9 connected to the cylindrical body 4 is extended, and the rotary shaft 3 inserted and supported within the cylindrical body 4 is inserted into the rotary shaft 3.
Lift it upward together with the motor 2 connected to the rear end.

In this state, as shown in FIG. 2, the part of the lid 15 that closes the upper end of the work holding member 13 comes into contact with the stopper 16 provided at the tip of the rotating shaft 3, and the work holding member 13 is closed. A brush 1 is housed therein.

When the work W is carried in and positioned at a fixed position, the piston rod 10 of the cylinder 9 is contracted, and the rotary shaft 3 inserted and supported within the cylindrical body 4 is lowered and attached to the tip of the rotary shaft 3. The brush 1 thus prepared is inserted into the hole 12 of the workpiece W.

At this time, the work holding member 13 attached to the tip side of the cylindrical body 4 is pressed against the work W, and at the same time, it is pushed against the elasticity of the spring 14 from the tip to the rear end of the rotating shaft 3. Move relatively (as shown in Figure 1).

As a result, the workpiece W is securely fixed by the workpiece holding member 13 strongly pressed by the elasticity of the spring 14.

In this state, the motor 2 is operated to rotate the rotary shaft 3, and the brush 1 at the tip of the rotary shaft 3 is rotated within the hole 12 of the work W to brush the inside of the hole 12.

In addition, when the piston rod 10 of the cylinder 9 is expanded and contracted with a predetermined stroke during brushing,
The brush 1 moves up and down inside the hole 12 of the workpiece W, and the inside of the hole 12 is thoroughly cleaned.

When the cleaning inside the hole 12 is completed in this way, the motor 2 is first stopped, and then the piston rod 10 of the cylinder 9 is extended to lift the rotary shaft 3 inserted and supported in the cylindrical body 4 upwards, and the rotational shaft 3 is lifted upward. The brush 1 attached to the tip of the shaft 3 is pulled out from the hole 12 of the workpiece W.

At this time, the work holding member 13 moves toward the tip of the rotary shaft 3 due to the repulsive force of the spring 14 and returns to the position where it contacts the stopper 16.
The brush 1 extracted from the hole 12 of the workpiece W is housed inside the brush 1 (as shown in FIG. 2), and the workpiece holding member 13 is completely separated from the workpiece W together with the brush 1 to hold the workpiece W. will be automatically canceled.

As described above, according to this example, the rotary shaft 3 is driven by an extremely simple mechanism in which the cylinder 9 drives the cylindrical body 4, through which the rotary shaft 3 rotatably driven by the motor 2 is inserted and supported, up and down. The brush 1 attached to the tip of the workpiece W is inserted into and removed from the hole 12 of the workpiece W positioned at a fixed position, and
The inside can be cleaned automatically.

Therefore, it is fully profitable as an automatic cleaning device for metal pipes and bulk metal materials having perforations that are mass-produced to some extent based on certain standards, and productivity can be improved.

The brush 1 is not limited to a normal wire brush or an abrasive brush containing alundum or corundum; for example, as shown in FIG. 3, a wire 21 is implanted on the surface of a shower nozzle 20 that sprays cleaning liquid A cleaning brush etc. can be used.

That is, FIG. 3 is a sectional view of a main part showing another embodiment of the present invention, in which the whole or part of the rotating shaft 3 that is rotationally driven by the motor 2 is formed into a hollow tube. A shower nozzle 20 communicating with the inside of the hollow tube and serving as a brush 1 is attached.

A rotary connector C consisting of a sealed bearing 22 is used as a bearing 5 that rotatably supports the rotary shaft 3 inserted into the cylindrical body 4. A cleaning liquid supply pipe 23 is connected.

In this case, the burrs, etc. remaining in the hole 12 of the work W can be removed by brushing with the wire 21 of the rotating brush 1, and at the same time, the removed burrs, etc. can be washed away with the cleaning liquid sprayed from the shower nozzle 20. As a result, the cleaning effect is very good.

Note that the shower nozzle 20 is the shaft of the brush 1.
If the part is formed of a flexible tube such as a metal bellows, even if the hole 12 of the workpiece W is curved, the brush 1 can be smoothly inserted into the hole 12 and cleaned reliably.

[Effect of idea]

As described above, the present invention has an extremely simple structure in which a cylinder drives a cylindrical body that inserts and supports a rotary shaft that is connected to a motor and is rotationally driven. At the same time as the brush is inserted into and removed from the hole in the workpiece, the workpiece holding member attached to the tip side of the cylindrical body is also connected to and removed from the workpiece, thereby automatically cleaning the inside of the hole in the workpiece. It has the effect of being able to. Therefore, the present invention is sufficiently profitable as a device for cleaning the inside of holes in pipe parts and block materials that can be mass-produced to some extent, such as automobile parts, and can automate the cleaning work and contribute to improving productivity.
