Benefits of technology

The present invention provides a barrel polishing device that can polish both the front and back sides of a workpiece simultaneously, increasing the polishing efficiency. The device includes a polishing medium storage tank, a workpiece supporting shaft, and a baffle member placed in the vicinity of the back side of the workpiece. The baffle member interferes with the flow of the polishing media, increasing the surface pressure of the polishing media with respect to the back side of the workpiece. This results in uniformed polishing and enhanced coating adhesion and strength. The device can also adjust the surface pressure of the polishing media with respect to the back side of the workpiece, expanding the application range. The baffle member is formed of elastic material, maintaining its endurance even at high flow pressure. The baffle member can be placed in the vicinity of the lower part of the back side of the workpiece to increase the surface pressure of the polishing media with respect to the back side at the lower part of the workpiece.

Problems solved by technology

Accordingly, the flow of the polishing media stored in the back side of the workpiece is interfered with the baffle.

Embodiment Construction

[0022] In the embodiments to be described hereinafter, a “vehicle wheel” will be employed as one example of a workpiece.

[0023]FIG. 1 is a sectional view of a barrel polishing device according to one embodiment of the present invention, FIG. 2 is a view when viewed in a direction as indicated by an arrow II of FIG. 1, FIG. 3 is a view when viewed in a direction as indicated by an arrow III of FIG. 1, FIG. 4 is a sectional view taken on line IV-IV of FIG. 3, and FIG. 5 is a view like FIG. 1 but showing another embodiment of the present invention.

[0024] In FIGS. 1 and 2, reference symbol B denotes a barrel polishing device and 10 denotes its base. Reference numeral 20 denotes a polishing media storage tank which is mounted on the base 10. This polishing media storage tank 20 is in the shape of a circular cylinder. The polishing media storage tank 20 is turnable in a peripheral direction about an axis O by an appropriate turning means (see an arrow of FIG. 1, indicating the turning di...

Abstract

A barrel polishing device for polishing a workpiece having a relatively complicated shape such as a vehicle wheel. The barrel polishing device comprises a polishing medium storage tank for storing polishing media, a base, a workpiece supporting shaft mounted on the base, and a workpiece detachably mounted on a tip part of the workpiece supporting shaft, the polishing media stored in the polishing medium storage tank being flowed by an appropriate means, and the workpiece supporting shaft being disposed so that a front side of the workpiece opposes the flow of the polishing media, the workpiece supporting shaft being rotated about an axis thereof, and a baffle member being placed in the vicinity of a back side of the workpiece.

Description

TECHNICAL FIELD [0001] This invention relates to a barrel polishing device which is used for barrel polishing, for example, a vehicle wheel. BACKGROUND ART [0002] Conventionally, when a vehicle wheel is to be barrel polished, it was an ordinary practice that the front side of the vehicle wheel is arranged in such a manner as to oppose to the flow of polishing media in the state slanted forward, and the side of the vehicle wheel is polished by flowing the polishing media along the front side of the vehicle wheel while rotating the vehicle wheel (about the axis). [0003] The polishing media, which have polished the front side, are turned from the perimeter of the vehicle wheel and stored in the back. [0004] In this conventional barrel polishing method, however, the back of the vehicle wheel is difficult to polish because the polishing media stored in the back side of the vehicle wheel are flown away backward while turning by the turning force of the vehicle wheel. [0005] It is, therefo...
