As shown in FIGS. 1 to 13 , the molded body support device 1000 may include a lower plate 100 , a mounting fixing part 200 , an upper plate 300 , and a grip part 400 .

The molded body support device 1000 is mounted and fixed to the wheel rotating plate 10 , and is configured to rotate together with the wheel rotating plate 10 .

Here, the lower plate 100 is provided on the upper portion of the wheel rotating plate 10 , and is configured to rotate together with the wheel rotating plate 10 .

A plurality of fastening holes 110 are formed on the lower surface of the lower plate 100 , and the operator engages the mounting fixing unit 200 at the position of the fastening hole 110 suitable for the size of the wheel rotating plate 10 to combine the lower plate 100 . ) can be coupled to the wheel rotating plate 10 . The mounting fixing unit 200 is configured to couple the lower plate 100 and the wheel rotating plate 10 .

Here, the plurality of fastening holes 110 formed on the lower surface of the lower plate 100 are continuously formed along the circumferential direction. At this time, the continuously formed fastening hole 110 may be formed such that the radius from the center C of the lower plate 100 is gradually shortened. That is, the fastening holes 110 are formed so that the radii between the adjacent fastening holes 110 are different from each other. Accordingly, by selectively changing the position of the mounting fixture 200 coupled to the fastening hole 110 according to the size of the wheel rotating plate 10 , even if the size of the wheel rotating plate 10 is different, the lower plate 100 is the wheel rotating plate (10) can be stably mounted and fixed.

In the present invention, the fixing holes formed in the mounting fixing part 200 are formed in two rows in order to firmly couple the mounting fixing part 200 to the lower plate 100, and the fixing holes do not necessarily have to be formed in two rows, 1 Of course, it may be formed in a plurality of rows other than a row or two rows. In the present invention, since the fixing holes formed in the mounting and fixing unit 200 are in two rows, the fastening holes 110 formed in the lower plate 100 also have a pair of fastening holes 110 aligned with the bolts and the fixing holes. A form coupled by the same fastening member will be described.

As such, the fastening holes 110 continuously formed along the circumferential direction of the lower plate 100 are formed so that the radii between the adjacent fastening holes 110 are different from each other. In this case, a radial distance from the center C of the lower plate 100 to the adjacent fastening hole 110 may be 1 mm. That is, if the fastening hole 110 is divided for convenience of explanation, for example, if the distance d1 from the center C of the lower plate 100 to the first fastening hole 101 is 210 mm, the neighboring second 2 The distance d2 to the fastening hole 102 may be 209 mm. In addition, the distance d3 from the second fastening hole 102 to the adjacent third fastening hole 103 may be 208 mm.

In the present invention, a form in which five fastening holes 110 are formed continuously along the circumferential direction as such a pair is described as an example. In this way, the grouped region in which the five fastening holes 110 are continuously arranged is referred to as a fastening hole area part 120 , and a plurality of such fastening hole area parts 120 may be disposed on the lower plate 100 . This is to enable the mounting fixing unit 200 to be coupled to the wheel rotating plate 10 of various sizes for the wheel rotating plate 10 .

Here, the fastening hole region part 120 is made to be symmetrical with respect to the center C of the lower plate 100 , so that the mounting fixing part 200 mounted on the fastening hole 110 is stably coupled to the spinning wheel 10 . can

And, instead of continuously forming 10 fastening holes 110 showing a difference of 1 mm in radial distance between the adjacent fastening holes 110 from the center C of the lower plate 100, those formed with only 5 are continuously formed. This is because the fastening hole 110 is too long. In this case, when the operator mounts the mounting fixing unit 200 to the fastening hole 110 , it is inconvenient to have to check the coupling positions of the fastening holes 110 one by one. In addition, there is a problem that the fastening hole region 120 cannot be distinguished from each other.

Therefore, in a state where the fastening hole region part 120 shows a distance difference of 1 mm and the number of fastening holes 110 continuously arranged along the circumferential direction of the lower plate 100 is limited to five, the mounting fixing part 200 is The mounting fixing part 200 may have the first mounting part 210 and the second mounting part 220 having different lengths so that all distances of 1 to 10 mm can be adjusted.

Here, the first mounting part 210 may include a first mounting body part 211 and a first supporting fixing part 212 .

A plurality of first fixing holes 213 forming predetermined intervals along the longitudinal direction may be formed in the first mounting body 211 . A distance between the first fixing holes 213 spaced apart along the longitudinal direction of the first mounting body 211 may be, for example, 10 mm. The number of the first fixing holes 213 formed in the longitudinal direction of the first mounting body part 211 is not limited to a specific number, but may be formed in various numbers.

And a first support fixing part 212 is provided at an end of the first mounting body part 211 . The first support fixing part 212 is configured to be fixedly mounted on the circumference of the spinning wheel 10 .

Meanwhile, the second mounting unit 220 may include a second mounting body unit 221 , a second support fixing unit 222 , and a length adjusting unit 223 .

Here, the second mounting body part 221 is formed with a plurality of second fixing holes 224 forming predetermined intervals along the longitudinal direction like the first mounting body part 211 . The second mounting body 221 has the same configuration as the first mounting body 211 .

And the second support fixing part 222 is made to be mounted and fixed around the wheel rotating plate 10 like the first support fixing part 212 .

And the length adjustment part 223 is provided between the second mounting body part 221 and the second support fixing part 222 . The length adjusting unit 223 is formed so that the distance from the end of the supporting fixing unit to the fixing hole of the first mounting unit 210 and the second mounting unit 220 is different from each other.

For example, in the first mounting part 210 , the distance d4 from the end of the first supporting fixing part 212 to the first fixing hole 213 disposed closest to the first supporting fixing part 212 is 10 mm. can be made with And in the second mounting unit 220, the distance d5 from the end of the second supporting fixing unit 222 to the second fixing hole 224 disposed closest to the second supporting fixing unit 222 may be 15 mm. have. As described above, as the length adjusting unit 223 having a length of 5 mm is provided in the second mounting unit 220 , the first mounting unit 210 and the second mounting unit 220 may have a length difference of 5 mm.

In this way, when the first mounting part 210 and the second mounting part 220 are formed so that the distance from the end of the supporting fixing part to the fixing hole has a length difference of 5 mm, the fastening hole area part 120 described above is 1 mm As the number of fastening holes 110 continuously arranged along the circumferential direction of the lower plate 100 is limited to five, the distance of 5 mm can be adjusted so that the distance between the The distance of ~10mm is made to be adjustable in 1mm increments.

For example, in coupling the first mounting part 210 to the fastening hole 110 in the fastening hole region part 120, the first fastening hole 101, In the process of coupling to the second fastening hole 102 and the like, the distance from the center C of the lower plate 100 to the first support fixing part 212 can be adjusted from 200 mm to 204 mm in a total distance of 5 mm.

And in coupling the second mounting part 220, not the first mounting part 210, to the fastening hole 110 in the same fastening hole region part 120, the first fixing hole 224 is designated in advance. In the process of coupling to the fastening hole 101, the second fastening hole 102, etc., a total distance of 5 mm from 205 mm to 209 mm may be adjusted.

In this way, by selectively coupling the first mounting part 210 and the second mounting part 220 to the fastening holes 110 continuously arranged along the circumferential direction, from the center C of the lower plate 100 to the support fixing part The distance may be selectively adjusted, and along with this, the distance from the center (C) of the lower plate 100 to the support fixing part may be selectively adjusted through the fixing holes spaced apart at intervals of 10 mm along the longitudinal direction of the mounting body part.

Therefore, through the selective use of the first mounting part 210 and the second mounting part 220, the operator can precisely control the distance from the center (C) of the lower plate 100 to the support fixing part in units of 1 mm. have.

On the other hand, on the upper surface of the lower plate 100, a spiral guide portion 130 forming a single spiral in the outward direction from the center of the lower plate 100 is formed.

The spiral guide unit 130 is configured to guide the movement of the grip unit 400 . The spiral guide unit 130 has a spiral groove shape and guides the movement of the grip unit 400 .

Here, the spiral guide part 130 may be densely formed while forming a single spiral form from the center of the lower plate 100 . Accordingly, the moving distance of the grip unit 400 may be more precisely controlled. That is, since the spiral guide unit 130 having a single spiral shape may have a small spiral pitch, it is possible to precisely control the movement distance of the grip unit 400 . Accordingly, the grip part 400 may stably fix the ceramic molded body 1 .

An open portion 131 communicating with the outside is formed at the end of the spiral guide portion 130 . The grip part 400 may be sequentially inserted into the spiral guide part 130 through the opening part 131 . The process of inserting the grip part 400 to be inserted into the opening part 131 will be described later.

Meanwhile, the upper plate 300 is provided on the lower plate 100 . The upper plate 300 is coupled by a lower plate 100 and a coupling member (not shown), and the coupling member prevents separation into the upper plate 300 and the lower plate 100 and at the same time the upper plate 300 is To be positioned on the same center line as the lower plate (100).

A movement guide hole 301 is formed in the upper plate 300 .

The upper plate 300 and the lower plate 100 are rotated together according to the rotation of the spinning wheel 10 in a state of surface contact with each other. However, when the balance of the forces applied to the lower plate 100 and the upper plate 300 is broken, that is, when different forces (pressure or centrifugal force) are applied to the upper plate 300 and the lower plate 100, the upper plate 300 is made to rotate independently from the lower plate 100 .

For example, when the operator rotates the wheel rotating plate 10 while holding the upper plate 300 with a certain force or more, the upper plate 300 is fixed to the wheel rotating plate 10 in a fixed state and the lower plate ( Only 100) is made to rotate together with the wheel rotating plate (10).

Here, the grip part 400 inserted into the movement guide hole 301 of the upper plate 300 through the opening 131 of the spiral guide part 130 formed in the lower plate 100 is rotated only by the lower plate 100 . It moves toward the center of the upper plate 300 along the movement guide hole 301 . In this case, the rotational direction of the spinning wheel 10 is a counterclockwise rotation as an example.

In other words, while the lower plate 100 rotates together with the wheel rotating plate 10, the guide protrusion provided under the grip part 400 is moved along the spiral guide part 130 formed on the lower plate 100, and the grip part ( The path guide provided in the 400 may be moved toward the center of the upper plate 300 along the longitudinal direction of the movement guide hole 301 while being inserted into the movement guide hole 301 .

The auxiliary grip portion 440 is configured to support the ceramic molded body 1 seated on the upper plate 300 in a state coupled to the first auxiliary grip support portion 413 .

Such an auxiliary grip part 440 may include an insertion rod 441 and an elastic arm pressing part 442 .

One end of the insertion rod 441 is configured to be inserted and fixed into the insertion hole 417 , and the insertion rod 441 may be supported and fixed to the first auxiliary grip support part 413 .

And an elastic arm pressing part 442 is provided at the other end of the insertion rod 441 . The elastic arm pressing part 442 is configured to support the ceramic molded body 1 in a state in which the ceramic molded body 1 is elastically pressed.

It goes without saying that the auxiliary grip portion 440 may include various types of auxiliary grip portions 440 having different lengths of the insertion rod 441 and the shape of the elastic arm pressing portion 442 .

Meanwhile, the molded body support device 1000 may further include a clamp 500 .

The clamp 500 is configured to fix the upper plate 300 and the lower plate 100 . The clamp 500 is inserted into the opening 131 formed in the lower plate 100, the movement guide hole 301 formed in the upper plate 300, and the slide support groove 302 with the upper plate 300 and It is made to fix the lower plate 100 . The clamp 500 may be made of an elastic material such as rubber, and is configured to integrally fix the upper plate 300 and the lower plate 100 in a state in which they are closely coupled to the upper plate 300 and the lower plate 100 .

Here, the operator fixes the upper plate 300 and the lower plate 100 integrally through the clamp 500 in a state in which the grip part 400 supports and fixes the ceramic molded body 1 seated on the upper plate 300 .

As such, when the clamp 500 fixes the upper plate 300 and the lower plate 100 , the upper plate 300 is prevented from rotating independently from the lower plate 100 . That is, the upper plate 300 and the lower plate 100 rotate in the same manner.

When the clamp 500 stops the spinning wheel rotating plate 10 , backlash is generated in the upper plate 300 , and the grip part 400 supporting the ceramic molded body 1 moves to the outside along the movement guide hole 301 . to prevent it from moving in the right direction.

In other words, when stopping the spinning wheel rotating plate 10 , if there is no clamp 500 , the lower plate 100 directly mounted on the wheel rotating plate 10 and fixed is stopped in the same way as the wheel rotating plate 10 , whereas the upper The plate 300 is rotated more than the lower plate 100 by centrifugal force. When such backlash of the upper plate 300 occurs, the grip part 400 moves along the movement guide hole 301 in the case where the upper plate 300 is fixed and only the lower plate 100 is rotated. Contrary to the movement toward the center of the 300 , the grip part 400 moves in the outer direction of the upper plate 300 along the movement guide hole 301 . In this case, the grip part 400 that elastically presses the ceramic molded body 1 and supports and fixes the ceramic molded body 1 is separated from the ceramic molded body 1, and when the spinning wheel 10 is stopped, the ceramic molded body 1 may fall over and be damaged.

Accordingly, by inserting the clamp 500 between the upper plate 300 and the lower plate 100 , even when the spinning wheel rotating plate 10 is stopped, the grip unit 400 can elastically press the ceramic molded body 1 .

However, this is only a preferred embodiment of the present invention, and the scope of the present invention is not limited by the scope of the present invention.
