Description

[Detailed description of the invention] The present invention is a sliding fitting part of a joint or a pot of glassware for physical and chemical experiments, that is, a plug that fits airtightly into the inner peripheral wall surface of the socket part of the joint or a pot. The present invention relates to a sliding polishing device for glassware for physical and chemical experiments, which finishes the outer peripheral wall surface of a glassware to specified dimensions and polishes it transparently at the same time.

The permissible dimensional error of the connecting fitting part of this type of glassware is specified by the JIS standard to be within 3/1000 mm. It requires advanced polishing techniques to polish to a perfect finish.

Conventionally, metal fittings for polishing the socket part of the fitting part of this type of glassware were made by cutting an iron plate approximately 2 mm thick into a fan shape and manually bending it into a conical shape to make a copy of the stopper. A shape formed into a shape is used.
Then, fit this polishing fitting into a suitable holder, apply polishing sand to the inner peripheral wall surface of the socket, fit the socket into the metal fitting, and rotate the metal fitting together with the holder to polish. method was adopted.

However, it is a tedious job to make the above-mentioned metal fittings by hitting them with a hammer, etc., and the metal fittings made by this method not only cannot obtain a perfect circle and a straight line in the axial direction, but also have the specified dimensions that match the metal fittings as a model. It is almost impossible to make it in any way, and the dimensions of the polishing fittings that are made are not consistent. Therefore, if you polish the socket part with such a metal fitting, the metal fitting itself is not already the specified size, so it will inevitably be impossible to polish the socket part to the specified size, and the polished The size and shape of the socket are also not constant.

Therefore, in order to finish the socket part polished as described above within the tolerance specified by the JIS standard, during polishing, the socket part was removed from the metal fitting, and a model was applied to the socket part, so-called "Atari". It was necessary to apply a small amount of abrasive sand dissolved in water only to the "stretched" portions to reduce the amount of sanding, and to finish by repeating this process. Therefore, polishing using the conventional polishing tool described above requires a sophisticated polishing technique, and can only be performed by an experienced person. In addition, as the model is applied several times to the inside of the socket to which abrasive sand is attached during the polishing process of one socket as described above, the model is subject to significant wear due to the abrasive sand. As the model itself gradually deforms, there is a risk that even if it is polished to the model, the socket may not be finished within the allowable dimensional error.

Therefore, in recent years, attempts have been made to use press working to manufacture the metal fittings to the specified dimensions.
However, this also causes a back spring peculiar to press processing, making it impossible to manufacture metal fittings within a tolerance of about 3/1000 millimeters, and also preventing deformation due to heat when welding the joints of metal fittings. No matter how accurate the press mold is, the result is 1/10
There was an error of more than a millimeter, and it was not much different from hand-made metal fittings, so I was unable to obtain the desired product.

Furthermore, metal fittings made of iron plates are very hard, so during rotational polishing, the sand does not dig into the surface of the metal fittings, but instead moves like the balls of a ball bearing, causing the rolling friction to wear out the polishing metal fittings. This also has the disadvantage of causing dimensional errors.

Furthermore, the polishing of the stopper in the fitting portion of this type of glassware is almost entirely done manually. Therefore, not only does it require skill, but the work efficiency is poor, and it is almost impossible to finish the plug polished in the above manner to a specified size, and the size and shape of the plug are not uniform.

Conventionally, polishing sand was applied to the polished socket part and the plug that fits into the socket part according to the above dimensions, and the products were directly fitted together and rotated to rub together. A finishing method is used. According to this method, the product (socket and stopper) can be fitted in an airtight manner.

However, the dimensions of the products polished by the above method are not uniform, and therefore, they are not interchangeable. Therefore, the socket and stopper are used exclusively for each other, and if one of them is damaged (it is easily broken because it is made of glass), the undamaged device will also become unusable. Ivy.

The present invention focuses on the above, and the sliding fitting part of the joint or socket of glassware for physical and chemical experiments, that is, the inner circumferential wall surface of the joint or socket part and the outer circumferential wall surface of the stopper, can be easily connected without the need of skill. The object of the present invention is to provide a sliding and polishing device for glassware for physical and chemical experiments that can mechanically and efficiently perform final polishing to specified dimensions, uniformity, and compatibility. be.

In order to achieve the above object, the present invention provides a female grinder in which the outer circumferential wall surface is shaped like a stopper with substantially the same dimensions and shape as the outer circumferential wall surface of a model stopper, and the inner circumferential wall surface is formed into the shape of a stopper model. It consists of a male polisher formed into a cylindrical shape with substantially the same dimensions and shape as the inner circumferential wall surface, and an engagement slit of a desired width is formed in the female polisher from the distal end toward the proximal end. At the same time, the male polisher is formed with an engaging slit extending from the inner peripheral wall surface to the outer peripheral wall surface of the male polisher, extending from the distal end of the male polisher toward the proximal end. Sandpaper is wound around the outer circumferential wall of the container with the end thereof engaged with the engaging slit, and sandpaper is wound around the inner circumferential wall of the male polisher with the end thereof engaged with the engaging slit. along the inner peripheral wall surface of the male polisher, rotate both polishers, and polish the socket with the female polisher and the plug with the male polisher.

Polishing is done while pressing. During this polishing, sandpaper 5a
Alternatively, it is preferable to apply a small amount of water to the inner circumferential wall surface of the socket portion 12.

As a result of the above, the inner circumferential wall surface 12a of the socket portion 12 can be polished to have the same dimensions and shape as the outer circumferential wall surface of the sample stopper. Then, this polished socket part 12
is removed from the sander a, the rotation of the sander a is temporarily stopped, the used sandpaper 5a is replaced with a new one, and the sander a is rotated again to open another socket 12. It is polished in the same way as above.

Next, to explain the polishing of the plug, in FIG. 8, 13 is a plug (male joint);
The outer circumferential wall surface 13a is previously subjected to primary polishing using a desired polishing method to approximately a prescribed size. Therefore, as shown in FIG. 8, the male polisher b equipped with sandpaper 5b is rotated by a rotary machine, the plug 13 is held by hand and inserted into the main body 7 of the polisher b, and the plug 13 is inserted. Polish while applying appropriate pressure. During this polishing, it is preferable to apply a small amount of water to the paper 5b or the outer peripheral wall surface 13a of the stopper 13, as described above.

As a result of the above, the outer circumferential wall surface 13a of the stopper 13 can be polished to have the same dimensions and shape as the model inner circumferential wall surface of the socket. Then, the polished plug 13 is pulled out from the polisher b, the rotation of the polisher b is temporarily stopped, the sandpaper 5b is replaced with new sandpaper, and the polisher b is rotated to remove another plug 13 and the above-mentioned plug 13. It is polished in the same way.

In the example, only the polishing of the joint socket and plug is shown, but the socket and plug of the joint are also polished in exactly the same manner as described above.
