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 metal pipes and in perforations formed in bulk metal materials such as cylinder blocks and differential blocks, burrs may remain due to thread cutting during manufacturing or cast burrs may occur.
The inside of the hole is cleaned using a wire brush or a brush containing grindstone grains.

However, the reality is that this cleaning work relies solely on manual labor, which results in very low productivity.

The reason why cleaning work of pipes, cylinder blocks, etc. is not mechanized is that the pipe diameter and hole diameter vary depending on the type, and in particular, some pipes are irregularly shaped pipes that are curved like a bend. be.

For this reason, although the work of spraying a high-pressure shower into the holes of pipes, cylinder blocks, etc. to clean them 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, cylinder blocks, differential blocks, etc. used as parts of automobiles, it is not possible to mechanize the cleaning work inside the holes using brushes. It is considered to be fully profitable.

[Means for solving problems]

Therefore, an object of the present invention is to provide an automatic cleaning device that can automatically brush and clean the inside of a pipe or the inside of a perforation of a block that is mass-produced based on a certain standard using a simple mechanism.

That is, the present invention is an automatic cleaning device in which a brush is inserted into a hole of a workpiece positioned at a fixed position and rotated, and a workpiece holder is provided to hold and fix the workpiece to a base frame installed at a fixed position. A slider including a member, a rotary shaft having a brush at the tip, and a motor for rotationally driving the rotary shaft is attached so as to be movable toward and away from the workpiece, and the workpiece holding member is oriented toward the workpiece by a spring. The slider is engaged with the slider, which is previously urged to advance and is slid in a direction of retreat from the workpiece, so that the slider moves away from the workpiece against the urging force of the spring. Features.

[Effect]

According to the present invention, first, the slider is engaged with the workpiece holding member, and the workpiece is positioned at a fixed position while the workpiece holding member is retreated in a direction away from the workpiece.

Next, the slider is slid toward the workpiece, and the brush at the tip of the rotating shaft provided on the slider is inserted into the hole of the workpiece.

At this time, the workpiece holding member, which had been engaged with the slider and separated from the workpiece, is advanced toward the workpiece by the biasing force of the spring, and presses and fixes the workpiece.

In this state, the motor provided on the slider 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 clean the inside of the hole.

When the cleaning inside the hole is completed, the motor is stopped and the slider is slid in a direction to retreat from the workpiece.

As a result, the brush at the tip of the rotating shaft is pulled out from the hole in the workpiece, and the workpiece holding member that was holding the workpiece is engaged with the slider and moves away from the workpiece against the biasing force of the spring. The workpiece is automatically released.
