Abstract

PURPOSE:To polish highly accurately by pivoting a spinning frame having a spinning shaft parallel with the revolving shaft at the outercircumference of revolving frame such that the axis of spinning frame will incline against the spinning shaft then holding many polishing tanks on the spinning frame and rotating the spinning frame and the revolving frame with proper speed. CONSTITUTION:The revolving frame 1 is journaled rotatably through spindle 3 to the base while spinning shafts 5, 5 at the opposite ends of spinning frame 4 for fixing a polishing tank are journaled between the outercircumferences of the opposite sideboards 1a, 1a of the frame 1. Material (a) to be polished is thrown together with abrasive (b) into respective polishing tank 17 and contained in respective partition 4C of spinning frame 4 to drive a motor 7 thus to rotate the spindle 3 and to revolve the spinning frame 4 around the spindle 3. Consequently, centrifugal force will function onto the spinning frame tank 4 to provide acceleration in radial direction of the revolving locus higher than the acceleration of gravity to the spinning frame 4 at anytime. Since the spinning shaft 5 and the inclined spinning frame 4 will perform pestle motion, materials (a), (b) contained in respective partition 4C will perform 8-character motion against acceleration thus to polish the entire circumference of material (a) uniformly.

Description

[Detailed description of the invention] The present invention relates to a polishing device for polishing.

Conventionally, when polishing watch parts, various sewing needles, injection needles, and other relatively small and complex articles of arbitrary shapes, an abrasive material is housed together with the article to be polished in a cylindrical sealed container. Various types of polishing devices are used to polish articles by rotating an oily sealed container to cause the contents to flow or vibrate to create a co-sliding effect. However, in this type of polishing device, the rotation speed of the cylindrical container is increased in order to increase the polishing rate, and when the angular velocity for each container diameter reaches a certain value or more, the contents exceed the gravitational acceleration. It sticks closely to the inner wall of the plate, and the flow is suppressed and the polishing action is reduced! L, which has the problem of making it impossible to obtain a polishing rate higher than a certain value, and the applicant has proposed a rotating nodal seal on the outer periphery of the main rotating body as patent No. 786191 (Utility Application No. We have provided a polishing device with a structure provided with a container.However, since this polishing device V uses a strong pressing force to apply abrasive layers, it is difficult to create scratches on the polishing surface due to the mutual rubbing of the objects to be polished. 1i1 with length that has the problem of leaving processed products
．． <I encountered a problem where it was not possible to uniformly polish each side of an article with a complicated shape.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a polishing apparatus that can uniformly and highly accurately polish articles with complex shapes, and is even more efficient.

That is, the polishing device of the present invention includes a rotating frame having an axis of rotation parallel to the axis of revolution of the rotating frame on the outer periphery of the rotating frame that is driven to rotate.
The rotating frame is pivoted so that its axis is inclined to the rotating axis, and the rotating frame is configured to house and hold one or a plurality of polishing tanks containing an article to be polished and an abrasive. The rotating frame is rotated at appropriate rotational speeds and rotational directions to rub and polish the object to be polished.

An embodiment of the polishing apparatus of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic front view of the entire apparatus, and FIG. 2 is a sectional view taken along line A7A in FIG. 1. (1) is a ft revolution frame which is rotatably mounted on a base (2) via a main shaft (3), and the outer periphery of both side plates (1a) (1a) of the revolution frame (1). A plurality of frames are arranged in between so as to be inclined at an angle with the rotating shaft (5) for attaching the polishing tank via a bearing member, and so that adjacent rotating frames (4) do not intersect with each other. It will be done.

(6) is a cheno wheel that is pivotally attached to the main shaft (3), and is driven and connected via an endless cheno belt (9) to a cheno wheel (8) that is pivoted on the drive shaft of the main drive motor (7). At the same time, the main motor (7) is a drive motor (+
01 and a brake device (10a).

In addition, (1υ is a drive wheel that is rotatably mounted on the main shaft (3), and the chain wheel (13) is pivoted on the drive shaft of the geared motor (12), which rotates via the chain belt (14). At the same time, the drive wheel (11) and the rotation axis (5) of each rotation frame (4) are connected to each rotation frame (4) via a Cheno wheel (inside is a Cheno wheel u6) attached to the K axis. ) 7 is the partition plate (4b)
[Therefore, it is divided into a plurality of sections (four sections) in the axial direction, and each section can accommodate one or more polishing tank σ forces and hold them without wobbling. The tank α force consists of a cylindrical or polygonal cylindrical hollow container,
It is constructed so that it can be sealed by a lid member u7a) which can be opened and closed freely.

In the polishing device having the above configuration, objects to be polished (a) such as watch parts and various sewing needles and injection needles are put into each polishing tank 07) along with an abrasive material (b), and these are placed in the rotating frame (4). Each section (4
C), the main drive motor (force and geared motor circle) is rotated to polish the article to be polished (a).

That is, as shown in Fig. 4, when the main drive motor (7) is driven, the main shaft (3) rotates via the Cheno belt (9) that is passed between the Cheno wheels (6) and (8). (3
) is integrated with the revolving frame (]) [A shaft installation force acts through the rotating shaft (5), causing the revolving frame (1) to rotate beyond a certain angular velocity, thereby rotating the revolving frame (1) (4) It is possible to give the VC a recognition acceleration in the radial outward direction of the orbit that is always larger than the gravitational acceleration. Therefore, each section C4C of the rotating frame (4) [accommodated polishing tank (17
) The article to be polished (fa) and the polishing PM (1)) housed in the grinding wheel (fa) are subjected to acceleration in the direction of one revolution around the shaft circumference for every revolution of the revolving frame (1). In this state, when the geared motor (121) is rotated, the drive wheel 01) rotates via the chain belt (QJ), and each rotating shaft (
Since the Cheno wheel (5) is rotationally connected, the rotating frame (4) attached to the rotating shaft (5) with an inclined shaft rotates the rotating shaft (5) while moving the shaft center by 4tll. Rotate around the center. Therefore, the polishing tank (I7) accommodated in each compartment (4C) of the rotating frame (4) also moves to collect powder together with the rotating frame (4), and the polished article (a) and the abrasive material (b) in the tank move. is the revolution frame (1
Due to the acceleration accompanying the rotational movement of ), the rotational movement of the rotating frame (4), and the inclination of the axis, a figure-eight flow occurs along the inner wall of the polishing tank (a).

Due to the figure-eight flow in the polishing tank (4) described above, the abrasive material (bl) is not the circumferential surface length of the article to be polished (a) but the end surface direction (
The VC also flows in pressure contact with the surface (the surface facing the polishing tank axis) so that the entire circumference of the article to be polished (a) is uniformly polished.

Furthermore, even if the rotation speed of the rotating frame (4) is increased, the revolving frame (1+
By increasing the rotational speed of -C and increasing the acceleration in the radial direction, the article to be polished (a) and the multi-layer material (b) in the polishing tank 07) come into pressure contact with the inner wall, resulting in a non-flowing state. Since there are no scratches, the polishing speed can be increased and the polishing process can be completed in a short time.

Furthermore, as in the above configuration, the main drive motor (7) that rotationally drives the main shaft (3) and the geared motor (12) that rotationally drives the rotational shaft (5) are configured using separate drive devices. It is now possible to easily change the rotation ratio and rotation direction of the rotation axis (5) and the rotation axis (5) using an electrical control mechanism (not shown), and the finished state of the polishing process can be adjusted in commemoration. is possible. In addition, especially the article to be polished (
a) When removing mutual scratches, the polishing tank (17) stores the objects to be polished (Al) in a distributed manner.
Since one to several pieces can be accommodated per K, highly accurate surface finishing can be achieved with no scratches.

As mentioned above, in the polishing apparatus of the present invention, the articles to be polished are housed in a dispersed manner in the grinder, so there are no rubbing marks between the articles to be polished, and the polishing apparatus relies on the figure-eight flow in the shattered tank. It has the characteristics of uniformly polishing the entire surface, and in addition, the finishing accuracy and processing speed can be freely adjusted, and the practical effects after implementing the present invention are extremely large.
