[0050] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0051] It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0052] During processing, it is often encountered that an integral one-piece processing solution is used. When the product ignores the size requirements, it can be mostly processed on the vertical axis. When the product has a high height and large size due to local characteristics, five-axis equipment or 3+2 equipment is often selected for processing. The processing cost is high, or an auxiliary inclined table can be made to support the product blank to meet the requirements of an ordinary gantry machining center. The machine tool processing cost is relatively low, but the processing cost and processing time of the fixture are increased, and the workload of the flipping process when processing the front and back sides of the blank is large. Due to various factors such as operation, the product accuracy will be unstable.

[0053] See also Figures 1 to 14The present invention provides a hollow rotating table that can adjust the processing angle of the blank 100 to achieve integrated processing of multiple angles on the front and back sides. The hollow rotating table includes a workbench 200, a rotation adjustment frame 300, a first support part 400, a hollow table 500, and a second support part. Two rotating adjustment frames 300 are arranged relatively on the workbench 200, and a rotatable rotating adjustment member 310 is provided on the rotating adjustment frame 300. The two ends of the hollow table 500 are respectively connected to the two rotating adjustment members 310. A blank 100 is installed on the hollow table 500. The blank 100 includes a first surface 110 facing the hollow table 500 and a second surface 120 away from the hollow table 500. The rotation angle of the hollow table 500 is adjusted by the rotating adjustment member 310, thereby adjusting the processing angle of the blank 100; the first support part 400 is arranged between the two rotating adjustment frames 300 and connected to the workbench 200; the second support part supports the hollow table 500 and / or the blank 100 during the processing to ensure the stability of the processing process.

[0054] See also Figures 1 to 14 When processing the first surface 110, the second support portion includes a semi-rotating ring block 600 and / or a first partial support member 700. The first partial support member 700 is connected to the hollowing table 500 and contacts the second surface 120. When processing the second surface, the second support portion includes a semi-rotating ring block 600 and a second partial support member 800. The second partial support member 800 is connected to the semi-rotating ring block 600 and contacts the first surface 110. The semi-rotating ring block 600 is supported and connected to the first support portion 400 and connected to the hollowing table 500. When processing the first surface 110, the semi-rotating ring block 600 and / or the first partial support member 700 ensure the support strength of the hollowing table 500 and / or the blank 100. When processing the second surface, the semi-rotating ring block 600 and the second partial support member 800 can support the hollowing table 500 and the blank 100, ensure the stability of the blank 100 during the flipping process, and ensure the processing quality of the blank 100. The structure of the semi-rotating ring block 600 enables the hollow platform 500 to be smoothly flipped and adjusted and is convenient for support and installation.

[0055] The hollow rotary table can be applied to a variety of machine tools for integrated processing of products without the need for making special fixtures, thereby improving the utilization rate of machine tools while reducing production costs and material costs and improving processing efficiency; the blank 100 is fixed on the hollow table 500 and rotates with the hollow table 500 to achieve integrated processing, and the flipping operation is simple and convenient. The position accuracy of the blank 100 can be guaranteed during the flipping process, and the strength of the hollow table 500 and the stability of the position of the blank 100 can be guaranteed by the first support part 400 and the second support part during the processing to ensure the stability of the processing process, thereby improving the stability of the product processing accuracy.

[0056] See also Figures 1 to 14According to an embodiment provided by the present invention, the number of semi-rotating ring blocks 600 can be one or two. For example, when the number of semi-rotating ring blocks 600 is two, the first semi-rotating ring block 610 and the second semi-rotating ring block 620 are respectively arranged on both sides of the blank 100 and are installed at different processing stages according to processing needs to ensure the stability of the blank 100 during the flipping process and provide support. When the blank 100 is processing the first surface 110, the first semi-rotating ring block 610 is connected to the hollowing table 500 and the first support part 400 to ensure the strength of the hollowing table 500. At this time, a first local support member 700 can also be provided on the second surface 120 to enhance the support for the blank 100. When the blank size is small, the first local support member 700 can also be not provided; when the blank 100 is flipped to the second surface 120 and processed, since the second surface 120 of the blank is not directly connected to the hollowing table 500, at this time, in order to ensure the flipping process To ensure the stability of the blank 100, a second support part needs to be set on the first surface 110 to support it before flipping. At this time, the second support part includes a second semi-rotating ring block 620 and a second local support member 800. The second semi-rotating ring block 620 can be rotated relative to the first support part 400 to smoothly flip the hollow table 500. The second local support member 800 abuts against the first surface 110 to ensure the stability of the blank 100 during flipping. When processing is performed after the flipping is completed, the second support part can also support the blank 100 and the hollow table 500.

[0057] It is understood that the two semi-rotating ring blocks 600 respectively support the hollowing table 500 during the front and back processing, ensuring a stable processing process and product quality even when the blank 100 is large and the processing intensity is high. In addition, the semi-rotating ring block 600 is detachably connected to the hollowing table 500. When the front and back surfaces are processed in one piece, the hollowing table 500 can be rotated by rotating the semi-rotating ring block 600 and the semi-rotating ring block 600 can be installed and removed from the corresponding side of the hollowing table 500 as needed to flip the blank 100 and process the first side 110 and the second side 120 respectively, which is convenient to operate.

[0058] In another embodiment, the number of semi-rotating ring blocks 600 can also be one. When the processing intensity is not high, the blank can be supported by the first local support member 700 during the processing of the first surface 110, and there is no need to set the first semi-rotating ring block 610. After the processing of the first surface 110 is completed, the second semi-rotating ring block 620 and the corresponding second local support member 800 are installed on the first surface 110 to ensure the stability of the blank 100 during the flipping process.

[0059] See also Figures 2 to 8According to an embodiment of the present invention, the rotary adjustment frame 300 includes a rotary adjustment member 310 and a support frame 320. The rotary adjustment member 310 is rotatably mounted on the support frame 320. The two ends of the hollow platform 500 are respectively connected to the rotary adjustment member 310. For example, a groove can be opened on the rotary adjustment member 310, and the two ends of the hollow platform 500 are engaged in the groove and fixed by bolts. When the hollow platform 500 is rotated and adjusted, the rotary adjustment member 310 on the support frame 320 rotates to the corresponding angle, driving the hollow platform 500 to rotate to the desired processing angle. To achieve accurate angle adjustment and ensure processing accuracy, the rotary adjustment member 310 is also provided with a dial. The dial is marked with scales according to processing requirements. The scale setting can be, for example, 5 degrees per unit to meet the requirements of processing the blank 100. Of course, in other embodiments, the minimum scale unit can also be set differently.

[0060] See also Figures 2 to 8 According to one embodiment of the present invention, a plurality of first limiting holes are provided on the rotation adjustment member 310 and the support frame 320. After the hollow platform 500 is rotationally adjusted, the first limiting members are inserted into the first limiting holes to secure the rotation adjustment member 310, thereby increasing the stability of the connection after angle adjustment and ensuring stable processing accuracy. Specifically, the first limiting holes are arranged on the rotation adjustment member 310 according to the minimum rotation unit of the scale. The plurality of first limiting holes are evenly distributed along the circumference of the rotation adjustment member 310, and the angle between two adjacent first limiting holes is equal to the minimum scale unit on the scale. For example, when the scale is set to 5 degrees per unit, the array rotation angle of the first limiting holes is also 5 degrees. The support frame 320 is provided with holes for corresponding connection. It is understandable that the number and distribution of holes on the support frame 320 can be set in various ways, but the angle between each hole is a multiple of the minimum rotation angle, so that it can be connected to the rotation adjustment member 310 through the first limit member. For example, when the scale is set as a unit of 5 degrees, the support frame 320 can have 6 connection holes evenly distributed along the circumference. These holes can be connected to the holes at corresponding positions on the rotation adjustment member 310 during the rotation adjustment process to achieve position fixing, ensure the stability of the angle adjustment, and prevent the product processing quality and accuracy from being affected. In other embodiments, the support frame 320 can also be provided with first limit holes corresponding to the scale units and holes corresponding to them can be provided on the rotation adjustment member 310 for fixation.

[0061] See also Figures 1 to 4The two ends of the hollow table 500 are respectively connected to the fixed frame 330 and the movable frame 340, and the hollow table 500 is convenient to install and disassemble.

[0062] See also Figures 1 to 2 According to an embodiment of the present invention, a plurality of movable grooves 210 are arranged parallel to the length direction on the workbench 200, and the fixed frame 330 and the movable frame 340 are arranged and symmetrically along the length direction of the workbench 200. A slider is provided at the bottom of the movable frame 340, and the slider moves in the movable groove 210 to adjust the relative position of the movable frame 340 and ensure that the opposite surfaces of the movable frame 340 and the fixed frame 330 are parallel to each other, so as to achieve stable installation of the hollow table 500; a plurality of connecting rods are provided along the length direction on both sides of the bottom of the movable frame 340 and the corresponding positions on both sides of the workbench 200. The connecting holes are arranged so that the movable frame 340 can be fixed to the workbench 200 after its position is determined, thereby ensuring the stability of the entire device. The multiple connecting holes on the workbench 200 are evenly spaced, and their spacing matches the moving unit of the movable frame 340. For example, the movable frame 340 can be a moving unit of 20 cm, and the corresponding workbench 200 has multiple connecting holes spaced 20 cm apart. Correspondingly, two connecting holes can be opened on both sides of the bottom of the movable frame 340 at intervals of 20 cm, and the movable frame 340 can be fixed to the workbench 200 by bolt connection to ensure the stability of the connection. It is understandable that the number and distribution of the connecting holes on the movable groove 210, the bottom of the movable frame 340, and the workbench 200 are not limited. The length of the moving unit is determined according to the on-site processing equipment and can have a variety of different settings.

[0063] See also Figures 3 to 9According to an embodiment of the present invention, the hollowing table 500 includes a hollowing table body 510, a fixed pressure plate 520, and a movable pressure plate 530. The hollowing table body 510 is connected to the rotary adjustment member 310 and rotates under the adjustment of the rotary adjustment member 310; the fixed pressure plate 520 is fixedly connected to the hollowing table body 510, and the movable pressure plate 530 is slidably connected to the hollowing table body 510 to adjust the distance between it and the fixed pressure plate 520, so as to adapt to the processing of blanks 100 of different lengths; the fixed pressure plate 520 and the movable pressure plate 530 are fixedly connected to both sides of the blank 100, fixing the blank 100 at a specified position on the hollowing table body 510, thereby determining the processing position of the blank 100. During the flipping process, the blank 100 rotates with the hollowing table 500 as a whole, which can well ensure the overall processing accuracy of the blank 100.

[0064] See also Figures 3 to 9 According to an embodiment provided by the present invention, the hollow table body 510 is a square frame structure as a whole, and its two ends are connected to the rotating adjustment member 310 for rotation. The blank 100 is installed on the hollow table body 510 through the fixed pressing plate 520 and the movable pressing plate 530, and can rotate with it to adjust the processing angle; since the hollow table body 510 is a hollow structure, after the blank 100 is installed on it, processing space can be reserved when processing at various angles on the front and back sides, so that multi-angle processing of the front and back sides can be achieved without multiple clamping of the blank 100, which reduces the amount of operation, improves processing efficiency, and reduces the impact on processing accuracy.

[0065] See also Figures 3 to 9 According to an embodiment provided by the present invention, the fixed pressing plate 520 is fixed on the hollow table body 510, and is located on the same side as the fixed frame 330. After the hollow table 500 is installed, the position of the fixed pressing plate 520 relative to the workbench 200 along the length direction is determined. The fixed pressing plate 520 is connected to one side of the blank 100, and the processing position in the length direction of the workbench 200 can be determined; the movable pressing plate 530 is connected to the other side of the blank 100, and can slide relative to the hollow table body 510 in the length direction of the blank 100. The installation of blanks 100 of different lengths can be achieved by adjusting the position of the movable pressing plate 530, which is more flexible to use and can be suitable for the processing of blanks 100 of various sizes.

[0066] Specifically, see Figures 5 to 7The fixed pressing plate 520 and the movable pressing plate 530 can be, for example, long strips with two sides perpendicular to each other and forming an angle, and threaded holes are provided at the extensions at both ends to achieve connection with the hollow table body 510. When the first side 110 of the blank 100 is processed, the blank 100 is connected and fixed to the hollow table 500 through the fixed pressing plate 520 and the movable pressing plate 530 to support the blank 100, thereby ensuring the stability of the blank 100 during processing; when the second side 120 is processed, the fixed pressing plate 520 and the movable pressing plate 530 are pressed on the second side 120 and both sides of the blank 100. At this time, a supporting component can be installed on the second side 120 of the blank 100 to achieve stable support of the blank 100 together with the two pressing plates. Of course, in other embodiments, the fixed pressure plate 520 and the movable pressure plate 530 can also be, for example, a U-shaped structure, which is located on both sides of the blank 100 and pressed on the first surface 110 and the second surface 120 of the blank 100. The pressure plate can achieve stable support for the blank 100 during processing of the first surface 110 and the second surface 120.

[0067] See also Figures 5 to 7 According to an embodiment of the present invention, a plurality of connection holes are symmetrically arranged on both sides of the center of the length direction of the fixed pressure plate 520 and the movable pressure plate 530, and the fixed pressure plate 520 and the movable pressure plate 530 are fixedly connected to the blank 100 through the connection holes.

[0068] See also Figures 5 to 7 According to an embodiment provided by the present invention, the connecting holes can be, for example, threaded holes, and the threaded holes on each pressing plate are symmetrically arranged on both sides of the center, so that the processing position in the width direction of the workbench 200 can be determined. Correspondingly, threaded holes are also symmetrically arranged on both sides of the center line along the width direction of the blank 100 on the surface of the blank 100, and at least two groups are arranged along the length direction of the blank 100. The pressing plate is connected to the corresponding threaded holes on the blank 100 by bolts, and the blank 100 is fixed to the fixed pressing plate 520 and the movable pressing plate 530, so that the processing position of the blank 100 can be completely determined; there are multiple threaded holes on each side of the fixed pressing plate 520 and the movable pressing plate 530 and they are evenly spaced, which can be connected to the threaded holes at different positions on blanks 100 of different sizes, and can adapt to the installation of blanks 100 of different widths. For example, on the fixed pressing plate 520 and the movable pressing plate 530, the threaded holes on both sides along the center line in the width direction of the workbench 200 can be symmetrically distributed at a distance of 100 mm plus 100 mm*n, that is, a plurality of threaded holes are evenly arranged at intervals of 100 mm on both sides of the center line to adapt to the connection holes at different positions on the blanks 100 of different widths, and the processing position of the blanks 100 is determined while fixing the blanks 100; in other embodiments, the number and distribution of the connection holes can also be set differently according to the production situation.

[0069] It should be noted that the hollow table 500 is connected to the fixed frame 330 and the movable frame 340, and the fixed pressure plate 520 is fixed at a fixed position on the hollow table body 510. At this time, the processing position of the workbench 200 in the length direction is determined by the fixed pressure plate 520, and the threaded holes symmetrically distributed on both sides of the fixed pressure plate 520 and the movable pressure plate 530 are used to determine the processing position of the blank 100 in the width direction of the workbench 200. At the same time, the surfaces where the fixed pressure plate 520 and the movable pressure plate 530 are connected to the blank 100 determine the processing position of the blank 100 in the height direction of the workbench 200, so that the processing coordinate system of the hollow rotary table has been determined, and it is only necessary to fix the blank 100 on the pressure plate. The setting of the movable pressure plate 530 and multiple threaded holes can adapt to blanks 100 of various sizes, which can effectively improve the processing efficiency and has a wide range of applications.

[0070] See also Figures 5 to 9 According to an embodiment of the present invention, two opposite sides of the hollow table 500 are provided with slide grooves 540. Both ends of the movable pressure plate 530 are slidably mounted in the slide grooves 540, so that the position of the movable pressure plate 530 can be adjusted relative to the hollow table body 510 in the slide grooves 540. One side of the blank 100 is fixed to the fixed pressure plate 520, and the other end is connected to the movable pressure plate 530. The fixed pressure plate 520 is fixed relative to the hollow table body 510. When the length of the blank 100 is different, the position of the movable pressure plate 530 is different. The movable pressure plate 530 can slide freely in the slide groove 540 to adjust to the appropriate position and connect to the other side of the blank 100. After the movable pressure plate 530 is connected to the blank 100, it is tightened and fixed in the slide groove 540 by, for example, bolting, so as to achieve a stable connection between the blank 100 and the hollow table 500, ensuring the stability of the position of the blank 100 during processing and ensuring processing accuracy.

[0071] It can be understood that the two sides of the blank 100 are connected to the fixed pressure plate 520 and the movable pressure plate 530, and a certain support space is left on both sides of the blank 100 without processing, so as to enhance the support strength of the blank 100 and ensure that the blank 100 can be stably supported during the front and back processing, thereby ensuring the stability of the processing process, and ensuring production efficiency and product quality.

[0072] See also Figures 2 to 12According to an embodiment of the present invention, the first support portion 400 is disposed between the two rotating adjustment frames 300 and connected to the workbench 200. A circular arc groove 410 is provided on the side away from the workbench 200, and a semi-rotating ring block 600 is rotatably installed in the circular arc groove 410.

The connection between the semi-rotating ring block 600 and the hollowing table 500 supports the hollowing table 500, thereby ensuring the strength of the hollowing table 500 during processing and achieving stable processing. Specifically, the semi-rotating ring block 600 is engaged with the arc-shaped groove 410 at the upper end of the first support portion 400. It can rotate relatively within the arc-shaped groove 410, thereby driving the hollow platform 500 to rotate. When the semi-rotating ring block 600 is fixed to the first support portion 400, the hollow platform 500 is supported by the first support portion 400. In other embodiments, the first support portion 400 can also be, for example, a bracket with an internal cavity structure, and its shape is not limited. The semi-rotating ring block 600 can rotate within its cavity and be relatively fixed thereto. Alternatively, a groove can be provided on the semi-rotating ring block 600, and the upper end of the first support portion 400 is a plate-shaped structure with a certain thickness and is located in the groove of the semi-rotating ring block 600.

[0073] It is understood that the number and distribution of the first support portions 400 may vary depending on the size of the workpiece 100 and the hollowing platform 500. For example, when the workpiece 100 is small, the number of first support portions 400 may be small or none may be provided, and the rotary adjustment member 310 may be sufficient to support the hollowing platform 500. When the processing intensity is high or the workpiece 100 is large, multiple first support portions 400 may be provided in conjunction with the semi-rotating ring block 600 to support the hollowing platform 500 and prevent deformation under stress that could affect processing quality.

When the blank 100 is flipped and adjusted, the semi-rotating ring block 600 rotates relative to the first support portion 400 to drive the hollowing platform 500 and the blank 100 to flip. When the blank 100 is surface-processed, the semi-rotating ring block 600 and the first support portion 400 are fixed by the connection between the second limiting member 640 and the second limiting holes 630 to ensure effective support for the hollowing platform 500. Here, the second limiting holes 630 and the second limiting member 640 can be threaded or pinned. The second limiting holes 630 are evenly distributed along the circumference, and their array angle is set according to the minimum angle adjustment unit on the dial of the rotation adjustment member 310, thereby enabling free adjustment of the rotation angle of the semi-rotating ring block 600 and achieving a fixed connection with the first support portion 400.

[0075] It is understood that, to adapt to the second limiting holes 630 on the semi-rotating ring block 600, the first support portion 400 is also provided with multiple second limiting holes 630. For example, the first support portion can be provided with four second limiting holes 630 and symmetrically distributed on both sides. When the semi-rotating ring block 600 rotates, some of the second limiting holes 630 thereon are aligned with the second limiting holes 630 on the first support portion 400. The first support portion 400 and the rotating ring block can be fixed by passing the second limiting member 640 through the two second limiting holes 630. In other embodiments, the number and distribution of the second limiting holes 630 on the first support portion 400 can also be set differently. The angle between each second limiting hole 630 is a multiple of the minimum rotation angle, so that it can be connected with the corresponding second limiting holes 630 on the semi-rotating ring block 600 during its rotation.

[0076] See also Figures 10 to 14According to an embodiment provided by the present invention, the semi-rotating ring block 600 includes a first semi-rotating ring block 610 and a second semi-rotating ring block 620.

It should be noted that when machining the first surface 110 of the blank 100, one side of the first surface 110 of the blank 100 provides a machining space. To preserve the machining space, the second partial support member 800 and the second semi-rotating ring block 620 do not need to be installed. It is understood that the second partial support member 800 can also be a single integral support structure or multiple evenly distributed bracket-like support structures.
