[0002] With the development of the processing and manufacturing industry, the requirements for processing accuracy are getting higher and higher, and thus the requirements for the accuracy of industrial clamping are becoming more and more stringent. Therefore, in order to ensure high-precision clamping of workpieces, it is usually necessary to prepare special high-precision clamping tooling for the workpieces to be processed, fix the workpieces to be processed, reduce the clamping error, and thus ensure the accuracy during processing.

[0046] With the development of the processing and manufacturing industry, the requirements for processing accuracy are getting higher and higher, and thus the requirements for the accuracy of industrial clamping are becoming more and more stringent. Therefore, in order to ensure high-precision clamping of workpieces, it is usually necessary to prepare special high-precision clamping tooling for the workpieces to be processed, fix the workpieces to be processed, reduce the clamping error, and thus ensure the accuracy during processing. In addition, when clamping some barrel-shaped products, it is also necessary to ensure that the coaxiality of the clamping meets the precision requirements.

[0047] However, even for the same type of workpieces to be processed, there are many specifications and models, so their external dimensions are all different, which requires the preparation of multiple high-precision clamping tools for the same type of workpieces to be processed. This not only leads to high manufacturing costs, but also because when the specifications of the workpieces to be processed are changed, the original clamping tooling needs to be disassembled and the new clamping tooling needs to be installed, resulting in long preparation time before processing and low processing efficiency.

[0048] Therefore, in order to ensure the coaxiality after clamping, improve the clamping accuracy, and adapt to a variety of different specifications of workpieces to be processed, this embodiment provides a multi-drive synchronous torsion mechanism.

[0049] like Figures 1 to 13As shown, the multi-drive synchronous torsion mechanism includes a workbench 1, a central core group 2, multiple rotation drive groups 3 and a centering component 4. The central core group 2 includes multiple layers of superimposed and independently rotatable torsion cores 21. The innermost torsion core 21 is rotatably connected to the workbench 1. One end of each layer of torsion core 21 is provided with a plug-in notch 211. The ends of the multiple layers of torsion cores 21 with the plug-in notches 211 are flush so that the plug-in notches 211 of the multiple layers of torsion cores 21 together constitute an adjustable plug-in groove 22. Multiple rotation drive groups 3 correspond one-to-one to the multiple layers of torsion cores 21 and are used to drive their respective corresponding torsion cores 21 to rotate. The centering component 4 includes a central shaft 41, a sliding drive member 42 and a plug-in joint 43. The central shaft 41 is slidably inserted in the innermost torsion core 21. The plug-in joint 43 is located on the side of the central core group 2 with the plug-in groove 22 and is connected to the end of the central shaft 41 extending out of the central core group 2. The sliding drive member 42 is used to drive the central shaft 41 to slide.

[0050] A plug-in notch 211 is provided on one side of the torsion core 21, so that a plug-in groove 22 is formed on the central core group 2 composed of multiple layers of superimposed torsion cores 21, thereby realizing adjustment of the rotation angle of different torsion cores 21 under the drive of the rotation drive group 3 corresponding to the multiple layers of torsion cores 21, thereby regulating the shape and size of the plug-in groove 22, so as to adapt to the clamping of workpieces to be processed of different specifications, with strong versatility, and a centering component 4 consisting of a central shaft 41, a sliding drive member 42 and a plug-in connector 43, so that the central shaft 41 drives the plug-in connector 43 to be inserted into the workpiece to be processed under the drive of the sliding drive member 42, completing the centering operation of the multi-drive synchronous torsion mechanism and the workpiece to be processed, thereby ensuring the coaxiality of the workpiece to be processed and the multi-drive synchronous torsion mechanism, and improving the accuracy after clamping.

[0051] The number of torsion cores 21 comprising the central core assembly 2 can be freely adjusted as needed. In this embodiment, eight layers of stacked torsion cores 21 are provided. To ensure the straightness of the sliding path of the central shaft 41 within the innermost torsion cores 21, the centering assembly 4 also includes a guide sleeve 44, which defines a guide hole sized to match the diameter of the central shaft 41. The guide sleeve 44 is attached to the innermost torsion core 21, and the central shaft 41 slidably extends through the guide hole.

[0052] In addition, in order to facilitate the connection between the sliding drive member 42 and the workbench 1, the centering component 4 also includes a connecting plate 45. The sliding drive member 42 is connected to the workbench 1 through the connecting plate 45, and the central axis 41 passes through the connecting plate 45 to connect with the sliding drive member 42.

[0053] Alternatively, as Figures 5 to 8As shown, the central core group 2 also includes a transmission gear disc 23 corresponding to the multi-layer torsion core 21. The transmission gear disc 23 is connected to the corresponding torsion core 21. The rotation drive group 3 includes a rotation drive member 31, a rotation shaft 32 and a drive gear disc 33. The drive gear disc 33 is engaged with the transmission gear disc 23 and is sleeved on the rotation shaft 32. The rotation shaft 32 passes through the workbench 1 and is connected to the rotation drive member 31. The rotation drive member 31 is connected to the workbench 1 and is used to drive the rotation shaft 32 to rotate. By adopting the engagement of the transmission gear disc 23 and the drive gear disc 33, the rotation drive member 31 drives the torsion core 21 to rotate, thereby having a higher transmission accuracy, thereby achieving precise control of the rotation angle of the torsion core 21.

[0054] In this embodiment, the rotating drive member 31 is a combination of a servo motor and a reducer. The encoder of the servo motor is used to accurately control the speed and angle of rotation of the rotating shaft 32, thereby achieving precise control of the rotation angle of the torsion core 21, so as to accurately adjust the plug-in slot 22, so as to improve the accuracy of installation and ensure the processing quality.

[0055] Alternatively, as Figure 1 、 Figure 3 As shown, the multi-drive synchronous torsion mechanism further includes a first adjustment assembly 5, which includes a first adjustment mounting block 51 and a first adjustment member 52. The first adjustment mounting block 51 is connected to the workbench 1. The first adjustment mounting block 51 is provided with an adjustment threaded hole. The first adjustment member 52 is provided with an adjustment thread that matches the adjustment threaded hole. One end of the first adjustment member 52 passes through the first adjustment mounting block 51 and abuts against the rotary drive member 31. By providing the first adjustment member 52 abutting against the rotary drive member 31, the position of the rotary drive member 31 is adjusted by screwing the first adjustment member 52, so that the rotating shaft 32 connected to the rotary drive member 31 drives the driving sprocket 33 to move, thereby adjusting the tooth gap between the driving sprocket 33 and the transmission sprocket 23, thereby ensuring the accuracy of the position between the two and improving the transmission efficiency.

[0056] In this embodiment, the first adjusting member 52 is a bolt, which is inserted into the adjusting threaded hole of the first adjusting mounting block 51 through a threaded connection. In this embodiment, the rotating driving member 31 is detachably connected to the workbench 1 through a bolt. Therefore, when the position of the rotating driving member 31 needs to be adjusted, the rotating driving member 31 can be separated from the workbench 1 first, and then the first adjusting member 52 can be rotated to achieve the position adjustment of the rotating driving member 31.

[0057] Alternatively, as Figure 3As shown, the rotary drive group 3 also includes a fixed seat 34, and the end of the rotary shaft 32 away from the rotary drive member 31 is rotatably inserted on the fixed seat 34, and the multi-drive synchronous torsion mechanism also includes a second adjustment component 6, and the second adjustment component 6 includes a second adjustment mounting block 61 and a second adjustment member 62. The second adjustment mounting block 61 is connected to the workbench 1, and an adjustment threaded hole is provided on the second adjustment mounting block 61. The second adjustment member 62 is provided with an adjustment thread that cooperates with the adjustment threaded hole. One end of the second adjustment member 62 passes through the second adjustment mounting block 61 and abuts against the fixed seat 34.

[0058] By providing a second adjusting member 62 that abuts against the fixing seat 34, the position of the fixing seat 34 is adjusted by screwing the second adjusting member 62, so that the rotating shaft 32 inserted in the fixing seat 34 drives the driving sprocket 33 to move, thereby adjusting the tooth gap between the driving sprocket 33 and the transmission sprocket 23, thereby ensuring the accuracy of the position between the two and improving the transmission efficiency. In addition, it cooperates with the first adjusting member 52 to ensure the verticality of the rotating shaft 32 and prevent the rotating shaft 32 from tilting due to unilateral adjustment.

[0059] In this embodiment, the second adjustment member 62 is a bolt that is threadably inserted into the adjustment threaded hole of the second adjustment mounting block 61. In this embodiment, the fixing seat 34 is detachably connected to the downstream equipment via the bolt to secure the rotating shaft 32. Therefore, when the position of the fixing seat 34 needs to be adjusted, the fixing seat 34 can be first separated from the downstream equipment, and then the second adjustment member 62 can be rotated to adjust the position of the fixing seat 34. In order to ensure the flexibility of the rotating shaft 32 in the fixing seat 34, a bearing is embedded in the fixing seat 34, and the rotating shaft 32 is inserted into the inner ring of the bearing.

[0060] Alternatively, as Figure 13 As shown, the driving gear disc 33 includes a toothed portion 331 and a covering portion 332, and the covering portion 332 is arranged on one side of the toothed portion 331. The driving gear disc 33 is also provided with a connecting through hole 333 that passes through the toothed portion 331 and the covering portion 332. The inner wall of the connecting through hole 333 is provided with a first key groove 334 extending from the toothed portion 331 to the covering portion 332, and the rotating shaft 32 is provided with a second key groove corresponding to the first key groove 334. The rotary drive group 3 also includes a connecting key, which is provided in the first key groove 334 and the second key groove.

[0061] By providing the covering portion 332 on the driving gear disc 33 in addition to the toothed portion 331 , the contact area between the driving gear disc 33 and the rotating shaft 32 is increased, thereby increasing the length of the connecting key and improving the anti-torsion performance of the connecting key.

[0062] In this embodiment, a threaded hole is provided in the second keyway, a through hole is provided on the connecting key, and the connecting key is connected to the second keyway by a bolt.

[0063] Alternatively, as Figure 3 As shown, the rotary drive assembly 3 further includes a limiting snap ring 35, which is mounted on the rotary shaft 32 and abuts against the side of the toothed portion 331 facing away from the covering portion 332. The limiting snap ring 35 provided on the rotary shaft 32 supports the bottom of the drive gear disc 33, reduces the force on the connecting key, and thus improves the strength of the overall structure.

[0064] In this embodiment, the limiting clamp 35 is made up of two arc-shaped parts, and the two arc-shaped parts are connected by bolts. Therefore, the strength of the limiting clamp 35 clamped on the rotating shaft 32 is achieved by the depth of the bolt connection, thereby achieving the connection between the limiting clamp 35 and the rotating shaft 32.

[0065] Alternatively, as Figures 5 to 8 As shown, the central core group 2 also includes a connecting disk 24 corresponding one-to-one to the multi-layer torsion core 21 and a bearing disk 25 arranged between two adjacent connecting disks 24. The connecting disk 24 is connected to the other end of the corresponding torsion core 21 away from the plug-in notch 211, and is provided with a through hole 242 for the upper-level torsion core 21 to pass through. The transmission gear disk 23 is connected to the side of the connecting disk 24 facing the upper-level torsion core 21. The bearing disk 25 is located on the side of the connecting disk 24 facing the next-level torsion core 21. The inner ring of the bearing disk 25 is connected to the connecting disk 24 corresponding to this level, and the outer ring of the bearing disk 25 is connected to the connecting disk 24 of the next-level torsion core 21.

[0066] By connecting the connecting disk 24 to the torsion core 21, the transmission gear disk 23 can drive the torsion core 21 to rotate through the connecting disk 24 when driven by the driving gear disk 33, and by arranging a bearing disk 25 between two adjacent connecting disks 24, and respectively connecting the two connecting disks 24 to the inner ring and outer ring of the bearing disk 25, the independent rotation of the torsion core 21 can be achieved.

[0067] Alternatively, as Figures 9 to 12As shown, a plurality of spaced-apart plugging protrusions 212 are provided on the other end of the torsion core 21 away from the plugging notch 211, and a plugging groove 241 corresponding to each of the plurality of plugging protrusions 212 is provided on the side of the connecting plate 24 facing the torsion core 21, and the plugging protrusions 212 are plugged into the plugging grooves 241. By providing the plugging protrusions 212 on the torsion core 21 and the plugging grooves 241 on the connecting plate 24, and plugging the plugging protrusions 212 into the plugging grooves 241, the positioning and assembly of the two are facilitated. On the other hand, the plugging protrusions 212 and the plugging grooves 241 are used to transmit the torsional force of the connecting plate 24 to the torsion core 21, thereby causing the connecting plate 24 to drive the torsion core 21 to rotate. Compared to directly bolting the connecting plate 24 to the torsion core 21, this method uses the plugging protrusions 212 as the main structure for bearing the torsional force, thereby preventing the bolts between the connecting plate 24 and the torsion core 21 from being subjected to shear force.

[0068] Alternatively, as Figure 9 、 Figure 10 As shown, except for the lowest-level torsion core 21, the remaining torsion cores 21 include a connecting portion 213 and an inserting portion 214 that are distributed in a stepped manner, and a first limiting step surface 215 is formed on the outer side of the torsion core 21, and a second limiting step surface 216 is formed on the inner side of the torsion core 21. The inserting groove 241 is provided on the side of the connecting portion 213 away from the inserting portion 214, and the inserting portion 214 is used to be inserted into the next-level torsion core 21 so that the first limiting step surface 215 abuts against the second limiting step surface 216 of the next-level torsion core 21.

[0069] The connecting portion 213 and the plug-in portion 214 form a stepped torsion core 21, so that when multiple torsion cores 21 are assembled, the first limiting step surface 215 abuts against the second limiting step surface 216 to achieve positioning during assembly and ensure assembly accuracy.

[0070] Alternatively, as Figure 1 As shown, the workbench 1 includes a work surface 11, support beams 12, and auxiliary support columns 13. The support beams 12 are connected to the four corners of the work surface 11. The auxiliary support columns 13 are connected to the same side of the work surface 11 as the support beams 12 and are located between two adjacent support beams 12. By providing the auxiliary support columns 13 between two support beams 12, the support strength of the work surface 11 is enhanced.

[0071] In this embodiment, when the multi-drive synchronous torsion mechanism is working, the work surface 11 as a whole will be subjected to a certain torsional force, which will cause the work surface 11 to collapse when the torsional force reaches a certain level. Therefore, auxiliary support columns 13 are provided to strengthen the support of the work surface 11, thereby ensuring that the work surface 11 will not collapse. The position and number of the auxiliary support columns 13 can be set by confirming the structural weak points through finite element simulation.

[0072] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
