Description

Technical Field

[0001] The present application relates to the field of motion platforms, and in particular to an angular rotation platform. Background Art

[0002] During the machining process, it is often necessary to process different positions of the workpiece. Therefore, the processing head (cutter, grinding head, welding gun, dispensing head, etc.) and the workpiece should be able to form free relative movement. The workpiece needs to be swung around the Z axis at a small angle, so a rotating platform is used to achieve this.

[0003] In the related technology, the rotating platform includes a platform base, a turntable, a motor screw module and a conversion transmission member. The turntable is in a truncated cone structure and is rotatably connected to the platform base, and the shape axis of the turntable coincides with the rotation axis; the motor screw module is horizontally arranged on the platform base; the conversion transmission assembly includes a roller and a guide block. The roller is rotatably arranged on the peripheral side of the turntable, and the roller rotates around its own shape axis. The guide block is connected to the sliding body of the motor screw module, and the guide block is provided with a guide groove. The length direction of the guide groove is perpendicular to the movement direction of the sliding body. The guide groove is for the roller to be movably embedded. During the linear motion of the sliding body, the roller will move relative to the guide groove close to the rotation center of the turntable, thereby realizing the conversion of the sliding of the guide block into the rotation of the turntable.

[0004] With regard to the above-mentioned related technologies, there is a defect that the rotation angle of the turntable depends on the length of the guide groove, so it is impossible to simultaneously achieve a small volume of the rotating platform and a large rotation angle of the turntable. Summary of the invention

[0005] In order to maintain a small volume of the rotating platform and increase the rotation angle of the rotating platform, the present application provides an angle rotating platform.

[0006] The angle rotation platform provided in this application adopts the following technical solution: An angle rotating platform, comprising: Platform base; A turntable, rotatably disposed on the platform base; A motor screw module is horizontally arranged on the platform base; A conversion active block is rotatably connected to the sliding body of the motor screw module, and the rotation axis of the conversion active block is parallel to the rotation axis of the turntable; The conversion driven block is arranged on the turntable, the conversion driven block is slidably connected with the conversion active block, and the sliding direction of the conversion driven block relative to the conversion active block is parallel to the diameter direction of the turntable.

[0007] By adopting the above technical solution, during the reciprocating linear motion of the sliding body of the motor screw module, the conversion active block will rotate, and relative sliding will occur between the conversion driven block and the conversion active block, thereby realizing the conversion of linear motion into circular motion. In this process, because the conversion driven block can follow the rotation, the relative motion stroke between the conversion driven block and the conversion active block can be larger, thereby making the platform small in size and having a larger rotation angle.

[0008] Preferably, a bolt roller is arranged between the conversion active block and the sliding body of the motor screw module, the roller end of the bolt roller is rotatably connected to the sliding body of the motor screw module, and the screw end of the bolt roller is fixedly connected to the conversion active block.

[0009] By adopting the above technical solution, with the help of bolt rollers, the connection between the conversion active block and the sliding body can be achieved through a simple structure, thereby maintaining a small volume of the platform.

[0010] Preferably, the conversion driven block is located above the conversion active block, and a sliding groove is provided on the lower surface of the conversion driven block, and the sliding groove is for the conversion active block to slide through, so as to achieve a drawer-type sliding connection between the conversion active block and the conversion driven block.

[0011] By adopting the above technical solution, the conversion driven block can be partially exposed outside the conversion active block, so the relative movement range between the conversion driven block and the conversion active block can be larger, thereby promoting the miniaturization of the platform while keeping the platform rotation angle unchanged.

[0012] Preferably, the turntable is divided into a central platform portion and a peripheral connecting portion, the central platform portion is cylindrical, and is rotatably connected to the platform base; the peripheral connecting portion is connected to the peripheral side of the central platform portion, and is provided with an installation groove, and the installation groove is used for fixing the conversion driven block.

[0013] By adopting the above technical solution, the distance between the conversion driven block and the center of the turntable can be changed. Then, when the distance between the conversion active block and the center of the turntable remains unchanged, the maximum stroke of the relative movement between the conversion active block and the conversion driven block can be changed, thereby slightly increasing the rotation angle of the platform without increasing the volume, thereby making it easier to assemble platforms with different working parameters.

[0014] Preferably, the central platform portion is provided with a supplementary groove at a position close to the peripheral connecting portion, and the supplementary groove is communicated with the installation through groove and is used to accommodate one end of the conversion active block close to the central platform portion.

[0015] By adopting the above technical solution, the portion of the conversion active block that does not overlap with the conversion driven block can be larger, which can increase the maximum stroke of relative movement between the conversion active block and the conversion driven block, so the platform's rotation angle can be increased while keeping the platform small in size.

[0016] Preferably, a power assist component is provided between the conversion active block and the conversion driven block, for applying an additional force to close or separate the conversion active block and the conversion driven block.

[0017] By adopting the above technical solution, the moving closer to and farther away from the conversion active block and the conversion driven block can be smoother, so the smoothness of the reciprocating rotation of the turntable can be improved.

[0018] Preferably, there is a gap between the bottom of the sliding groove and the upper surface of the conversion active block; the power-assisting component includes a permanent magnet and an electromagnet, the permanent magnet is arranged on the bottom of the sliding groove, and the electromagnet is arranged on the conversion active block, the electromagnet is closer to the rotation axis of the turntable than the permanent magnet, and the electromagnet repels or attracts the permanent magnet.

[0019] By adopting the above technical solution, with the help of the magnetic force between the permanent magnet and the electromagnet, suction or repulsion can be applied between the conversion active block and the conversion driven block, which can make the conversion active block and the conversion driven block move closer or apart more smoothly, while also maintaining the structural simplicity of the platform.

[0020] Preferably, the platform base is divided into a base part and a driving part, the base part is for setting the turntable, and the base part is used to be fixed on an external frame; the driving part is for setting the motor screw module, the driving part is slidably connected to the base part, and the driving part performs circular motion around the rotation axis of the turntable; a displacement component is arranged between the base part and the driving part, and the displacement component is used to drive the driving part.

[0021] By adopting the above technical solution, the driving part can be rotated with the help of the displacement component, which can also make the motor screw module rotate around the center of the turntable. Therefore, the rotation angle of the turntable can be increased without increasing the length of the motor screw module, thereby increasing the rotation angle of the platform while keeping the size of the platform small.

[0022] Preferably, the position shifting assembly includes a position shifting motor, a position shifting belt and a position shifting pulley, wherein the position shifting motor is arranged on the base portion; the position shifting belt is fixedly passed through the driving portion, and the position shifting belt surrounds the turntable; the position shifting pulley is connected to the output shaft of the position shifting motor, and the position shifting pulley abuts against the position shifting belt.

[0023] By adopting the above technical solution, while realizing the rotation of the driving part, the installation positions of the position-changing motor and the position-changing pulley can be more flexible, so that the rotating platform can be more flexibly installed in different positions of the automation equipment, thereby helping to improve the application flexibility of the rotating platform.

[0024] Preferably, a connecting track and a connecting seat are arranged between the driving part and the base part, the connecting track is annular, the connecting track is arranged around the turntable, and the displacement components are all located on the outside of the connecting track; the connecting seat is arranged on the driving part, and the connecting seat is slidably sleeved on the connecting track.

[0025] By adopting the above technical solution, the rotation range of the driving part relative to the base part can be increased without interfering with the operation of the displacement component. Therefore, the rotation angle of the platform can be increased, and the relative position between the driving part and the base part can be changed without removing the rotating platform, thereby improving the performance of the platform itself and the application flexibility of the platform.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the sliding body of the motor screw module makes reciprocating linear motion, the conversion active block will rotate, and relative sliding will occur between the conversion driven block and the conversion active block, so that the linear motion is converted into circular motion. In this process, because the conversion driven block can follow the rotation, the relative motion stroke between the conversion driven block and the conversion active block can be larger, so that the platform can have a large rotation angle while making the platform small in size; 2. With the help of the displacement assembly, the drive unit can be rotated, which can also make the motor screw module rotate around the center of the turntable. Therefore, the rotation angle of the turntable can be increased without increasing the length of the motor screw module, thereby increasing the platform rotation angle while keeping the platform small in size.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses an angle rotating platform.

[0034] Example 1 Reference Figure 1 and Figure 2 The angle rotation platform includes a platform base 1, a turntable 2, a motor screw module 3, a conversion active block 4 and a conversion driven block 5. The platform base 1 will be fixed on the external frame to serve as the installation basis of the entire platform; the turntable 2 is horizontally rotatably arranged on the platform base 1; the motor screw module 3 is horizontally arranged on the platform base 1; the conversion active block 4 is rotatably connected to the sliding body of the motor screw module 3, and the rotation axis of the conversion active block 4 is parallel to the rotation axis of the turntable 2; the conversion driven block 5 is arranged on the turntable 2, and the conversion driven block 5 is slidably connected to the conversion active block 4, and the sliding direction of the conversion driven block 5 relative to the conversion active block 4 is parallel to the diameter direction of the turntable 2.

[0035] Reference Figure 1 and Figure 2 In the process of the sliding body of the motor screw module 3 making reciprocating linear motion, the conversion active block 4 will rotate, and relative sliding will occur between the conversion driven block 5 and the conversion active block 4, so that the linear motion is converted into circular motion. In this process, because the conversion driven block 5 can follow the rotation, the relative motion stroke between the conversion driven block 5 and the conversion active block 4 can be larger, so that the platform can have a small size and a larger rotation angle at the same time.

[0036] Reference Figure 1 and Figure 2In order to keep the platform small in size and maintain a large rotation angle of the platform, the following settings are correspondingly arranged. First, the connection structure between the conversion active block 4 and the sliding body of the motor screw module 3 can be optimized. Specifically, a bolt roller 6 is arranged between the conversion active block 4 and the sliding body of the motor screw module 3. The roller end of the bolt roller 6 is rotatably embedded in the sliding body of the motor screw module 3, and the screw end of the bolt roller 6 is fixedly connected to the conversion active block 4. Therefore, with the help of the bolt roller 6, the connection between the conversion active block 4 and the sliding body can be more simply achieved.

[0037] Reference Figure 1 and Figure 2 Secondly, the matching structure between the conversion driven block 5 and the conversion active block 4 can be optimized. Specifically, the conversion driven block 5 is located above the conversion active block 4, and a sliding groove 51 is provided on the lower surface of the conversion driven block 5. The sliding groove 51 is for the conversion active block 4 to slide through. In this way, the conversion active block 4 and the conversion driven block 5 can be connected in a drawer-like sliding manner, and the maximum stroke of the relative movement between the conversion driven block 5 and the conversion active block 4 can be increased, thereby promoting the miniaturization of the platform while maintaining the rotation angle of the platform unchanged.

[0038] Reference Figure 1 and Figure 2 Thirdly, the connection structure between the turntable 2 and the conversion driven block 5 can be optimized. Specifically, the turntable 2 is divided into a central platform portion 21 and a peripheral connection portion 22. The central platform portion 21 is cylindrical and rotatably connected to the platform base 1. The peripheral connection portion 22 is integrally formed on the peripheral side of the central platform portion 21. The peripheral connection portion 22 is provided with an installation groove 221 for fixing the conversion driven block 5. With this structure, the maximum stroke between the conversion active block 4 and the conversion driven block 5 can be changed by changing the distance between the conversion driven block 5 and the rotation center without changing the distance between the conversion active block 4 and the center of the turntable 2. Therefore, the rotation angle of the platform can be slightly increased without increasing the volume. In addition, based on this structure, the rotation angle of the platform can be changed by using the position of the conversion driven block 5 while the reciprocating stroke of the sliding body remains unchanged. In this way, platforms with different working parameters can be assembled more simply.

[0039] Reference Figure 1 and Figure 2Fourthly, the matching structure between the turntable 2 and the conversion active block 4 can be optimized. Specifically, the central platform portion 21 is provided with a supplementary groove 211 near the peripheral connecting portion 22, and the supplementary groove 211 is connected with the installation through groove 221. The supplementary block can also accommodate an end of the conversion active block 4 near the central platform portion 21, so that the part of the conversion active block 4 that does not overlap with the conversion driven block 5 can be larger, and the maximum stroke of the relative movement between the conversion active block 4 and the conversion driven block 5 can be increased, so it is compatible with the small volume of the platform and the large rotation angle of the platform.

[0040] The implementation principle of an angle rotating platform in Example 1 of the present application is as follows: during the reciprocating linear motion of the sliding body of the motor screw module 3, the conversion active block 4 will rotate, and relative sliding will occur between the conversion driven block 5 and the conversion active block 4, thereby realizing the conversion of linear motion into circular motion. In this process, because the conversion driven block 5 can follow the rotation, the relative motion stroke between the conversion driven block 5 and the conversion active block 4 can be larger, thereby making the platform small in size and having a larger rotation angle.

[0041] Example 2 Reference Figure 3 and Figure 4 , which is different from Example 1, is that an assisting component 7 is provided between the conversion active block 4 and the conversion driven block 5. The function of the assisting component 7 is to apply a closing or separating force between the conversion active block 4 and the conversion driven block 5. At the same time, in order to accommodate the assisting component 7, there is a gap between the bottom of the sliding groove 51 and the conversion active block 4. Specifically, the assisting component 7 includes a permanent magnet 71 and an electromagnet 72. The permanent magnet 71 is fixedly mounted on the bottom of the sliding groove 51, and the electromagnet 72 is fixedly mounted on the conversion active block 4. Compared with the permanent magnet 71, the electromagnet 72 is closer to the rotation axis of the turntable 2. The electromagnet 72 repels or attracts the permanent magnet 71, so that there is an additional closing or separating force between the conversion active block 4 and the conversion driven block 5, so that the rotation of the turntable 2 can be smoother, while also keeping the structure of the platform simple.

[0042] Reference Figure 3 and Figure 4In order to further expand the rotation angle of the platform without increasing the volume of the platform, the following settings are correspondingly arranged. The platform base 1 will be divided into a base part 11 and a driving part 12. The base part 11 will be fixed on the external frame. The base part 11 is provided for rotation installation, and the driving part 12 is provided for the motor screw module 3 to be installed. The driving part 12 is slidably connected to the base part 11, and the driving part 12 will make a circular motion around the center of the turntable 2. At the same time, a displacement component 8 is also arranged between the base part 11 and the driving part 12. The displacement component 8 is used to move the driving part 12, so that the motor screw module 3 can be rotated around the center of the turntable 2. Therefore, the rotation angle of the turntable 2 can be increased without increasing the length of the motor screw module 3, thereby increasing the rotation angle of the platform while keeping the volume of the platform small.

[0043] Reference Figure 3 and Figure 4 In order to avoid increasing the difficulty of installing the rotating platform due to the displacement component 8, the displacement component 8 will include a displacement motor 81, a displacement belt 82 and a displacement pulley 83. The displacement motor 81 is fixedly mounted on the base portion 11, and the displacement belt 82 is fixedly passed through the driving portion 12. The displacement belt 82 surrounds the turntable 2, and the displacement pulley 83 is connected to the output shaft of the displacement motor 81. The displacement pulley 83 abuts against the displacement belt 82. The advantage of this structure is that the installation positions of the displacement motor 81 and the displacement pulley 83 can be more flexible, so that the rotating platform can be more flexibly installed in different positions of the automation equipment, thereby helping to improve the application flexibility of the rotating platform.

[0044] Reference Figure 3 and Figure 4 In order to further increase the rotation angle of the platform, it is necessary to optimize the structure between the driving part 12 and the base part 11. A connecting track 9 and a connecting seat 91 are arranged between the driving part 12 and the base part 11. The connecting track 9 is annular and arranged around the turntable 2. The displacement components 8 are all located on the outside of the connecting track 9. The connecting seat 91 is arranged on the driving part 12, and the connecting seat 91 is slidably sleeved on the connecting track 9. In this way, the rotation range of the driving part 12 relative to the base part 11 can be increased, thereby increasing the rotation angle of the platform. The relative position between the driving part 12 and the base part 11 can also be changed without removing the rotating platform, thereby improving the performance of the platform itself and the application flexibility of the platform.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
