JPH06143124A - Vibration barrel turning type jig - Google Patents

Abstract

PURPOSE:To carry out the uniform polishing free from unevenness by installing a polished member in a turnable manner around the specific axis of a jig. CONSTITUTION:A proper number of projection parts 21 which project aslantly upward and fix a polished member 25 are installed, keeping the proper intervals, on a pipe 20 which turns around the axis of a jig 10. In this case, two projection parts are opposed on the opposite sides of the pipe 20, and each pair are installed in deflection by 90 deg. around the axis. A shock softening member 23 for the turning movement of the pipe 20 is installed. During the barrel vibration, the jig 10 performs the gentle turning operation, accompanied with the shift of a medium. Accordingly, the formation of a struck flaw or the generation of the part free from the collision of the medium can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention stores a medium in a tank, and vibrates the tank to agitate the medium in the tank so that the member to be polished contained in the tank is agitated. The present invention relates to a vibrating barrel for polishing, and more particularly to a jig fixed to the vibrating barrel.

[0002]

2. Description of the Related Art A member to be polished is placed in a vibrating barrel tank as it is.

[0003]

When the member to be polished is put into the barrel tank as it is, there is a drawback that the members collide with each other and have a dent, especially a slight flaw,
It was unsuitable for polishing high-end ornaments where dents were not allowed. Further, when the fixing jig (FIG. 2) is attached to the barrel tank and the member to be polished is fixed to this jig, there is a drawback in that the member to be polished has a back side that is not polished and is not uniformly polished.

[0004]

In order to solve the above-mentioned problems, the member to be polished can be rotated around an axis.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. Figure 1
1 is a drawing showing an embodiment of the present invention, 10 is a jig, and 11 and 12 are portions for fixing the jig to a barrel tank.
1 is a structure for straddling the outer edge of the barrel tank, 12 is a structure for screwing to the edge of the central portion of the barrel tank, and 13 is a hole for a set screw. 20 is a pipe that revolves around the axis of 10.
An appropriate number of projecting portions 21 that obliquely upwardly project and fix the member to be polished 25 are provided at appropriate intervals. Here, 2
The book is shown facing the other side of the pipe 20, one pair at a time offset 90 ° about the axis. Reference numeral 23 is a buffer member for the turning motion of the pipe.

FIG. 2 is a drawing showing the structure when the jig to which the member to be polished is fixed does not rotate.

[0007]

With the structure capable of swiveling, the jig makes a slow swiveling motion along with the movement of the medium during barrel vibration, without making a dent or a part where the medium does not collide. It was possible to perform uniform and uniform polishing.
