Abstract

PROBLEM TO BE SOLVED: To beautifully polish the work surface of a wheel at once by arranging plural abrasive installing tools capable of reciprocating in the vertical direction, the longitudinal direction and the lateral direction and capable of optionally setting an installing angle and pressing force of sand paper. SOLUTION: A table 9 reciprocates in the vertical direction by a pneumatic cylinder 4a, a table 6 reciprocates in the longitudinal direction by a pneumatic cylinder 3a, an abrasive installing tool 2 reciprocates in the lateral direction by a pneumatic cylinder 10a, and reciprocates in the vertical direction by a pneumatic cylinder, respectively. Pressing force of an abrasive to a wheel is optionally set by adjusting air pressure to perform finer polishing work. In this case, finer reciprocating motion is made by interposing speed controllers in the respective cylinders to prevent the generation of a polishing stripe generated by continuously polishing the same place by the abrasive.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for polishing the surface of an aluminum wheel used in an automobile with an abrasive such as sandpaper.

[0002]

2. Description of the Related Art Aluminum wheels on which automobile tires are mounted are easily deformed or damaged due to traffic accidents, falling wheels, and the like. Repair of such deformed or damaged aluminum wheels is performed in a process of first repairing the deformed or damaged parts using a lathe or a press machine, and then performing a polishing operation.

[0003] This polishing operation is performed by a method such as buff polishing or sandpaper polishing. Of these, sandpaper polishing is usually performed by manually attaching wheels to a balancer for tire replacement and rotating the wheels at high speed.

[0004]

The conventional manual sandpaper polishing is a highly difficult and dangerous operation in which an operator manually performs sandpaper polishing. In addition, there is a risk that the hand may be burned due to frictional heat, and continuous work cannot be performed. Furthermore,
Aluminum powder may be scattered at the time of polishing, and workers may be injured by inhaling the aluminum powder.

[0005] Therefore, the present invention provides a wheel polishing apparatus which allows a worker to work safely and easily, and which can beautifully grind the worked surface of the wheel at one time and which does not cause any health damage. The purpose is to do.

[0006]

Means for Solving the Problems To solve the above problems, the present invention employs the following means.

[0007] A rotary table on which wheels can be mounted concentrically is provided.

[0008] Above the turntable, a vertical direction,
A plurality of abrasive attachments that can reciprocate in the front-rear direction and the left-right direction and that can arbitrarily set the attachment angle and the pressing force of the sandpaper are provided.

A dust suction port is provided on a side surface or a bottom surface, and dust is sucked and discharged from the dust suction port.

Hereinafter, the function of the solution will be described.

In the wheel polishing apparatus according to the present invention, the wheel to be polished is mounted concentrically on the rotary table, and the wheel to be polished is rotated by the rotation of the rotary table. Then, the polishing operation is performed by reciprocating up and down, back and forth, and left and right with an abrasive attachment having an abrasive such as sandpaper attached to the tip thereof. At this time, since the attachment angle of the abrasive can be set arbitrarily, it is possible to attach an abrasive such as sandpaper according to the angle of the surface to be polished of the wheel, and that there are a plurality of abrasive attachments. Therefore, if the abrasive is attached in accordance with the angles of various surfaces of the wheel to be polished, it becomes possible to grind various surfaces of the wheel at once. Also,
Since the pressing force of the abrasive can be set arbitrarily, the polishing strength can be set according to the condition of the scratch on the wheel, and a beautiful finish can be obtained.

As described above, according to the present invention, before the polishing operation, the operator sets the mounting angle of the abrasive such as sandpaper according to the surface angle of the wheel, and attaches the abrasive according to the size of the wheel. All that is required is to move the tool vertically and forward and backward. After that, since the abrasive attachment automatically repeats the reciprocating movement in the front-back, up-down, and left-right directions, the polishing work is automatically performed, so that the worker can work safely and easily, and moreover, once. Since various surfaces of the wheel can be polished in a short time, an efficient polishing operation can be performed. Specifically, the polishing operation by hand requires about 2 hours for one wheel, but the polishing apparatus according to the present invention performs the polishing operation for about 15 to 20 minutes per wheel. It becomes possible.

Further, since the pressing force of the abrasive on the wheel can be arbitrarily set, a beautiful finish can be obtained.

Furthermore, a dust suction port is provided on the side surface or the bottom surface, and the dust is sucked and discharged from the dust suction port. Therefore, it is possible to prevent the worker from sucking the aluminum dust generated by polishing, so that the worker can be prevented from sucking. It is possible to prevent health damage.
