Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a surface vibration polishing apparatus for small parts such as ceramics, which polishes the surface of small parts.

[Conventional technology]

When small parts made of ceramics are put in a furnace and fired, a spreading powder made of a material resistant to heat is placed, and the small parts are arranged and fired on this, but after baking, the spreading powder is The surface is polished because it adheres to the small parts.

The polishing apparatus used for the above-mentioned polishing is fixed to one object to be polished using one holder, and is polished in a powdery abrasive while being appropriately vibrated or moved, or a barrel tank. It was general to put small parts made of the above-mentioned ceramics in the above and barrel polish.

[Problems to be solved by the invention]

However, in the apparatus for fixing and polishing with one holder for one object to be polished according to the above-mentioned conventional example, it is necessary to increase the number of types of holders when there are many types of objects to be polished. Further, since the objects to be polished are polished one by one, there is a problem that the efficiency is poor.

Further, in the above-mentioned barrel polishing, it is necessary to replace the top, bottom, left, and right sides or the front and back sides at regular intervals in order to perform uniform polishing, which is troublesome, and since the object to be polished is not fixed, cracks or cracks due to mutual interference occur. However, there is a problem that may occur.

The present invention has been made in view of the above circumstances, and a surface vibration polishing apparatus for small parts that can simultaneously efficiently polish a plurality of small parts that are objects to be polished and that does not cause cracks or cracks during polishing. The purpose is to provide.

[Means for solving problems]

A surface vibration polishing apparatus for small parts according to the present invention which meets the above-mentioned object includes a mounting table on which a vibrator is attached and which mounts a plurality of small parts which are objects to be polished, and the small parts mounted on the mounting table described above. It comprises a mesh body which can be pressed and fixed and which can be raised and lowered, a reversing means for reversing the above-mentioned mounting table, and an abrasive tray in which the above-mentioned mounting table reversed by the reversing means is placed.

[Action]

In the surface vibration polishing apparatus for small parts according to the present invention, since the mounting table is provided with a vertically movable net body, the small parts arranged on the mounting table can be pressed and fixed by the net. Since the parts are pressed and fixed by the net body, the abrasive grains can freely move in and out around the small parts. Further, since the above-mentioned mounting table is provided with the reversing means, it is possible to put the small parts pressed and fixed to the mounting table into the abrasive tray.

In this state, drive the vibrator attached to the mounting table,
By applying vibration to the small component, the surface of the small component can be brought into contact with the abrasive grains for polishing.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention.

Here, FIG. 1 is a side view of a surface vibration polishing apparatus for small parts according to an embodiment of the present invention, FIG. 2 is a partially omitted plan view of the surface vibration polishing apparatus for small parts, and FIG. It is a partial side view showing an operating state of a surface vibration polishing device for small parts.

As shown in FIG. 1, a surface vibration polishing apparatus 10 for small parts according to the present invention comprises a mounting table 12 to which a vibrator 11 is attached, a net 13 for moving up and down on the mounting table 12, and the mounting table described above. It has a reversing means 14 for reversing 12 and a lower abrasive tray 15. These will be described in detail below.

The above-mentioned mounting table 12 is composed of a rectangular table, and a pallet 16 made of a rubber plate is placed on the upper part thereof, and a vibrator 11 using a motor or an electromagnet is mounted on the lower part thereof.

Elevating means for raising and lowering the net body 13 is provided on both sides of the mounting table 12.
17 is provided. The lifting means 17 includes air cylinders 18 and 19 attached to the lower part of the mounting table 12 and a net body 13.
The guide columns 20 and 21 attached to the
The air cylinders 18, 19 include guides 22, 23 of 20, 21, and connecting plates 24, 25 for connecting the ends of the guide columns 20, 21 and the rods of the air cylinders 18, 19, respectively. With the expansion and contraction of the guide columns 20, the guide columns 20 and 21 are moved up and down, and the net body 13 fixed to the upper part is moved up and down.

As shown in FIG. 2, the net body 13 is smaller than the size of the small parts arranged in the central portion, and has a net 26 having an opening of a size sufficiently larger than the diameter of the abrasive grains described below.
And the mounting frame 27 thereof, and the guide columns 20 and 21 are fixed to the mounting frame 27 via mounting members, respectively.

Rotation shafts rotatably attached to bearings 28, 29, 30 fixed to supporting bases (not shown) on both sides of the mounting base 12
31 and 32 are installed. A pinion gear 33 is attached to the rotary shaft 31, and a rack 34 attached to a hydraulic cylinder that is an example of a drive source (not shown) for driving the pinion gear 33 meshes with the expansion and contraction of the hydraulic cylinder. , The mounting table 12 is shown by an arrow 18 in FIG.
It is designed to rotate 0 degrees.

As shown in FIG. 1, an abrasive material tray 15 is arranged at the bottom of the above-mentioned mounting table 12, and the abrasive material tray 15 is composed of a vessel having a square diameter sufficiently larger than that of the above-mentioned mounting table 12. A hydraulic lifter 35 for adjusting the height of the abrasive tray 15 is attached to the lower part.

Next, the method of using the surface vibration polishing apparatus 10 for the small parts and the operation thereof will be described in more detail.
As shown in the figure, the air cylinders 18 and 19 are contracted and the net 13 is raised with the mounting table 12 in the upper part.

Next, small parts (for example, ceramic pieces) 36 to be polished are placed at appropriate intervals on the pallet 16 that constitutes the mounting table 12, the air cylinders 18 and 19 are extended, and the net body 13 is formed.
And the small parts 36 are pressed and fixed, the hydraulic cylinder constituting the reversing means 14 is driven to move the rack 34, the mounting table 12 is rotated 180 degrees, and the small parts 36 are directed downward.

Then, when the lower abrasive tray 15 containing the abrasive grains 37 is moved up and down by the hydraulic lifter 35, it is brought into pressure contact with the small component 36, the vibrator 11 is turned on, and the mounting table 12 is vibrated. The small parts fixed to the mounting table 12 are polished by the abrasive grains 37, whereby the spread powder and the like adhering to the surface can be removed.

Incidentally, here, the portion contacting the pallet 16 will not be polished, but if necessary, by driving the reversing means 14,
It is also possible to reverse the mounting table 12 to the state as shown in FIG. 1, raise the net body 13 on the upper side to reverse the small parts, and repeat the above steps to polish.

[Effect of device]

As is apparent from the above description, the surface vibration polishing apparatus for small parts according to the present invention can polish a large number of objects at once if the small parts that are objects to be polished have substantially the same shape. .

Further, since the object to be polished is fixed by the net during polishing, it is not affected by interference like the barrel polishing method and cracks are not generated.

Further, when the object to be polished has a constant shape, the polishing is performed with a constant pressure, so that the working time can be shortened and a uniform polished state can be obtained.
