[Detailed description of the invention]

[0001]

TECHNICAL FIELD The present invention relates to a small potter's wheel for manually rotating a turntable for forming, painting and finishing a plastic material made of ceramics. Belong to.

[0002]

2. Description of the Related Art Conventionally, a lathe having a light metal turntable with concentric circles for forming is used to process a plastic material into a desired shape, and a lathe requiring a center stop of a different structure is formed. After semi-drying or unglazing, the work is done on high ground or painting work.To obtain the finished product, it is necessary to have a plurality of working wheels with different functions or to place the object directly on the molding wheel. It was fixed with raw dry clay or fixed with a sitter.

[0003]

[Problems to be solved by the invention] In recent years, pottery has become popular as a hobby, it does not aim at mass production, it rotates at a relatively low speed without requiring special skill, and the rotation speed can be freely controlled. There is an increasing demand for a small, hand-held potter's wheel that is easy to handle. In the process from the ceramic plastic material to the finished product, a working wheel for forming, a painting wheel, or a high-level milling machine is indispensable. Since this work device is a heavy burden, it has been an obstacle to the popularization of hobby pottery, and it has been required to provide an easy-to-use work wheel that can be used for multiple purposes.

[0004]

[Means for Solving the Problems] In the past, in the case of producing a fired product, at least a potter's wheel for molding and a potter's wheel for painting or high-level milling were indispensable except the firing furnace in the process from material to product Although a plurality of workbenches were used, a plurality of centering pins work together to fix a work object in the center of the workbench for painting or hillsaw work. At the outermost position of the fitted centering pin, the removable disk-shaped turntable with the same number of holes for fitting as the head of the centering pin is placed to mount the plastic material. In order to enable the forming process and to increase the torque due to the centrifugal force of the rotating plate that rotates at a free speed with one hand, the metal disk is made of steel with a large specific gravity instead of the conventional light metal, and the speed is extremely low. Painting work and pretty fast plastic molding In order to perform the material forming work on the same workbench, it is appropriate to have a structure that allows the turntable to be replaced, and has a lathe structure that has a material and shape that provides an appropriate rotation speed for each work. I was able to conceive of the idea that there is.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION A circular support pillar made of metal is erected vertically near both ends of a gantry, and centering pins are interlocked with a work object on one of the support pillars to rotate in opposite directions. By attaching two steel discs that can be fixed in the center by doing so, arc-shaped grooves are drilled in three places of the discs, and three centering that can move the object movable in interlock with the grooves. By providing a pin, the work object can be fixed to the center of the disk. In addition, a wooden turntable having a hole into which the head of the centering pin can be fitted is attached to the upper disc so that it can be removably fitted. On the other hand, a structure will be provided on the support column that can move up and down, left and right, and can be rotated to support the elbow of the worker during work. When forming a plastic material, place the material on a turntable and rotate the table with one hand while rotating it at the required speed. After removing the fitted turntable, placing the object on the metal disc and rotating the metal discs in opposite directions, move the three centering pins to the center along the groove and fix them. , While rotating the metal plate with one hand, shaving or painting. When shaving a high platform, the arm of the dominant hand is placed on an elbow rest on a support stand attached to the opposite side of the metal disk, and the mechanism is designed so that the working hand does not vibrate.

[0006]

[Example] A steel support cylinder 2 having a diameter of about 30 mm and a height of 180 mm is set up at approximately the center of one end of a pedestal bottom plate 1 having four corners made of steel of about 450 mm × 200 mm × 5 mm, and the upper end thereof A circular plate made of steel and iron with a thickness of about 5 mm and a diameter of 350 mm, which can rotate with each other, is attached to the upper plate, and the upper plate has a circular arc shape from the trisecting point near the outer edge of the circumference toward the center. A protrusion for rotation operation, which has a groove 4 and a lower disk having a groove symmetrically with the upper disk and having a head at the lower part of the disk for maintaining a distance from the upper disk 3A. By attaching a centering pin 5 that fits into each groove 4 of both discs and moves along the groove, the head part of which can be replaced with a round bar, and by rotating the operation protrusion, By moving the centering pins 5 to the center, the object on the disk is fixed near the center. The structure is fixed. Further, when the centering pin 5 is at the outermost position, a wooden disk 6 having a thickness of about 30 mm and a diameter of about 400 mm and having a hole capable of fitting with the head of the centering pin is detachably installed. I'll do it. A steel hollow cylinder having an outer diameter of about 30 mm and a height of 180 mm is erected approximately at the center of the other end of the pedestal bottom plate 1, and a steel cylinder having an outer diameter of about 20 mm and a height of 150 mm which can slide is inserted into the cylinder. A hollow rectangular steel frame plate 8 having a length of about 230 mm and a width of 30 mm is screwed onto the upper part of the column, and a working arm having a length of about 380 mm, a width of 80 mm and a thickness of 15 mm is mounted on the frame plate. An elbow pad 9 to be placed is attached so that it can move up and down and left and right, and it can rotate around the screw on the top of the cylinder. It is convenient to work by changing the position of the arm during work arbitrarily. Be prepared to fix it. First of all, when forming the plastic material, the armrest 9 on which the arm is placed is set up vertically, and the wooden turntables on the disc are placed at three places to fit on the metal disc, and near the center. Place the clay lump on the table and manually rotate the workbench to perform forming work. When the head of the centering pin 5 is a round bar, it is replaced with the first one having a plastic head and then the turntable is fitted. In addition, a hole is formed in the front of the elbow pad 9 for inserting a drill or flat plate so that the head of the finishing tool can be mounted.

[0007] Next, in order to process and carve up the hill at the time of semi-drying, the turntable is removed, the armrest 9 is returned to a substantially horizontal state, and the work target object is placed on the disk in the substantially central portion. The discs are rotated in opposite directions, and the three centering pins 5 are moved toward the center to fix the object, and the work table is manually turned to perform the work of mounting or scraping the work. In this case, the centering pin 5 and the direction of rotation of the work table are aligned with each other so that the object is not loosened during work. After drying or bisque-ring, the object is fixed by the same operation as above, and the painting work is performed while turning the position of the object. In this case, if it is not necessary to use the armrest 9, the armrest 9 is set upright.

[0008]

[Effect of the Invention] If the work for mounting or shaving up a hill is performed on a forming lathe, it is necessary to fix the object with a lump of clay or to fix it with a sitter. However, it may take some time to remove the clay adhering to the object after the work, and it may damage the shape of the object, and it also takes time to manufacture the sitter. In contrast to this, the present invention has the feature that a single workbench can be used by removing or attaching the wooden turntable plate.

[0009] Aiming at mainly unskilled hobbyists, they are characterized by being able to perform work at low speed and with variable speed, and being extremely safe, and being able to use according to the skill of the worker.

By using steel having a larger specific gravity instead of the conventional light metal as the material of the metal disc, the inertial force of the steel is increased to facilitate the work.

By removing the head of the centering pin and replacing the round bar with a length of 30 mm to 60 mm, it is possible to ensure the fixation of a high-height molded body, and also to have a circular cross section. Since it can be fixed either on the inside or outside of the building so that it is easy to work on, it has the feature that painting work, work on a hill, etc. can be performed by the method most suitable for the object.

By attaching a drill-like tool or the tip of a flat plate to the front part of the elbow pad in a detachable manner, it can be used as a toescan or a planing tool to perform other operations such as molding, painting, and scooping. Since it can also perform finishing work, it also has the feature that it can play the role of several work benches.
