[0002] In modern manufacturing, producing high-precision, high-quality parts and products requires more sophisticated machining equipment and technologies, which undoubtedly poses new challenges to the machining and transport precision of automated production equipment. Currently, many automated equipment systems utilize rotary machining tables. High-precision rotary machining tables need to ensure the horizontal parallelism and level of one or more machining surfaces, and also need to ensure that the machining surfaces are subjected to less impact and vibration during high-speed rotation start-up and shutdown, quickly reaching a stable state.
[0003] Most vibration damping structures for worktables involve adding damping pads at multiple locations between the support and the worktable, and fixing the worktable with screws passing through the damping pads. However, it's difficult to ensure that the compression of each damping pad is consistent, affecting the levelness of the worktable. Leveling structures for worktables often use shims and adjusting bolts to adjust the levelness, but the leveling operation is cumbersome and may cause the worktable to bend and deform under stress. Coaxial top-pull leveling structures are also used, but some of these structures have line-to-surface contact points, which may cause unstable contact and lead to additional vibrations.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0040] See Figures 1 to 6 This utility model discloses a vibration-damping worktable for rotary machining, comprising a rotary motor 10, a supporting rotating arm 3, multiple machining surfaces 2, and a composite vibration-damping structure 1. The rotary motor 10 is mounted on a base 11. The supporting rotating arm 3 includes a central cantilever seat 32 and multiple cantilever arms 31 arranged circumferentially therearound. The output end of the rotary motor 10 is connected to the center of the cantilever seat 32, and the rotary motor 10 is located below the supporting rotating arm 3. Each cantilever arm 31 is provided with a machining surface 2, and each machining surface 3 is connected to the cantilever arm 31 through at least one corresponding composite vibration-damping structure 1.
[0041] The composite vibration damping structure 1 includes a sleeve 6 and a locking screw 9. The sleeve 6 passes through and is connected to the cantilever 31; the locking screw 9 passes through the sleeve 6, and the end of the sleeve 6 is threaded to the machining table 2. The sleeve 6 has a hollow stepped cylindrical structure inside, and includes a vibration damping groove 61, a through hole 63, and a spring groove 64 in sequence. The inner diameter of the through hole 63 is smaller than the inner diameter of the vibration damping groove 61 and the spring groove 64. The composite vibration damping structure 1 also includes an elastic vibration damping head 5 and a spring 7 sleeved on the locking screw 9. Preferably, the spring 7 is a rectangular spring. The elastic vibration damping head 5 is located in the vibration damping groove 61, with one end contacting the bottom surface of the vibration damping groove 61 and the other end embedded in a groove at the bottom of the machining table 2 that matches its shape. The spring 7 is located in the spring groove 64, with one end contacting the top surface of the spring groove 64 and the other end contacting the end cap of the locking screw 9.
[0042] The outer diameter of the end cap of the locking screw 9 is not greater than the inner diameter of the spring groove 64, and / or the length of the spring 7 satisfies the condition that the end cap of the locking screw 9 always extends a certain distance beyond the spring groove. During installation, the threaded end of the locking screw 9 passes sequentially through the spring 7, the through hole 63, and the elastic damping head 5 and extends to the machining table 2, connecting to the machining table 2 through threaded engagement with the threaded hole 24.
[0043] During the processing process in which the material on the processing table 2 is rapidly rotated and stopped by the support arm 3, the support arm 3 and the processing table 2 will generate strong forced vibrations in the vertical direction each time they rotate to the position and stop.
[0044] The elastic contact of the elastic damping head 5 effectively suppresses the vertical vibration amplitude generated after rotation into position. Simultaneously, the energy absorption effect of the composite damping structure allows the vibration to decay to an equilibrium state more quickly. This reduces the vibration amplitude after rotation and accelerates the vibration decay rate, thereby reducing the time spent waiting for the table vibration to stabilize before processing. It also avoids processing errors caused by attempting to save time before the table is stable, thus enabling continuous high-precision processing and material transfer. Furthermore, this composite damping structure ensures the initial levelness of the processed material and has a leveling function.
[0045] Furthermore, the locking screw 9 compresses the spring 7 with a certain preload and connects to the processing table 2, ensuring that the relative position of the processing table 2 and the cantilever 31 does not change during the rotational processing. At the same time, since the spring 7 is only compressed and fixed but not completely compressed and ineffective, the spring 7 can also play an auxiliary role in absorbing the micron-level vertical vibration generated during the rotation of the table, reducing the vibration amplitude after the table is in place.
[0046] In a preferred embodiment, the elastic vibration damping head 5 of this invention can be made of vibration damping materials such as elastic polyurethane, rubber-based vibration damping materials, or other grease-based vibration damping materials. The preferred hardness range of the vibration damping material is Shore A60 to Shore A90. If the hardness is too low, the compression and deformation of the elastic vibration damping head 5 will be too large, causing its vibration damping effect to fail. If the hardness is too high, the vibration damping effect will be insignificant. Specifically, the appropriate material and hardness can be selected according to the processing environment of the worktable and the vibration damping requirements.
[0047] More preferably, the bottom of the processing table 2 is provided with a clamping threaded hole 24, which matches the threaded end of the locking screw 9, so that the locking screw 9 and the processing table 2 are threadedly connected.
[0048] More preferably, the top of the elastic damping head 5 is a convex structure or a planar structure, and the bottom of the processing table 2 is provided with a groove that matches its shape, with the convex structure or planar structure in surface contact with the groove. In a non-limiting embodiment, the top of the elastic damping head 5 is a hemispherical convex body 51, and correspondingly, the bottom of the processing table 2 is provided with a spherical groove 21, which is located at the bottom of the clamping threaded hole 24. The hemispherical convex body 51 of the elastic damping head 5 and the spherical groove 21 at the bottom of the processing table 2 are in contact, and the radius of the hemispherical convex body 51 and the spherical groove 21 are the same, so that the two are in surface contact.
[0049] Of course, the upper structure of the elastic damping head 5 is not limited to the above-mentioned hemispherical structure. It can also be a planar or conical structure or other structures. Accordingly, the groove at the bottom of the processing table 2 can be set to match the top of the elastic damping head 5 to ensure that the two are in surface-to-surface contact and improve the stability of the contact.
[0050] More preferably, a washer 8 is provided between the end cap of the locking screw 9 and the spring 7. One end of the spring 7 contacts the spring groove 64, and the other end contacts the washer 8. The washer 8 can increase the contact area between the locking screw 9 and the spring 7, ensuring locking stability. Furthermore, the outer diameter of both the washer 8 and the end cap of the locking screw 9 is not greater than the inner diameter of the spring groove 64; and / or, the length of the spring 7 satisfies the following condition: both the washer 8 and the end cap of the locking screw 9 always extend a certain distance beyond the spring groove 64. That is to say, the washer 8 is not locked with the sleeve 6, thereby helping the spring 7 to play an auxiliary role in absorbing the micron-level vertical vibration generated during the rotation of the table.
[0051] More preferably, such as Figure 6 As shown, each cantilever 31 includes two support arms 313 extending outward toward the center away from the cantilever seat 32. The bottom surface of each support arm 313 is an inclined plane 314, that is, the thickness (vertical height) of the support arm 313 gradually decreases in the outward extension direction. This can reduce the rotational inertia of the support arm 3 while ensuring that the vertical strength of the cantilever 31 is not reduced, thereby further reducing the vibration when the processing table 2 is rotated into place.
[0052] More preferably, such as Figure 6 As shown, each cantilever 31 includes two support arms 313 extending outward toward the center away from the cantilever seat 32. The outer ends of the two support arms 313 of each cantilever 31 approach each other to form a tip structure 318. The tip structure 318, based on the ability to install a composite vibration damping structure, reduces the rotational inertia of the support arm 3 compared to other shapes, which can further reduce the vibration when the platform is in place, and at the same time increase the horizontal rigidity of the cantilever 31.
[0053] More preferably, in this embodiment, the processing platform 2 uses vacuum adsorption to stably support the object being processed. Specifically, as shown in the example... Figure 5 As shown, the processing table 2 is provided with several suction ports 23. The processing object is vacuum-adsorbed through the suction ports 23 to ensure that the processing object remains fixed relative to the processing table 2 when rotating. The suction ports 23 are connected to the air chamber 22 in the processing table 2, and the air chamber 22 is connected to the air pipe for air extraction.
[0054] More preferably, such as Figure 6As shown, the back of the cantilever 31 is provided with an air pipe groove 317, which serves as a mounting groove for the air pipe. The air pipe groove 317 also has an air pipe hole 316 that penetrates the cantilever 31, through which the air pipe can pass and connect to the air chamber 22. The air pipe groove 317 reduces the weight and moment of inertia of the cantilever 31, thus reducing the torque required to support the rotation of the swing arm 3. More preferably, a transverse support rib 315 is provided between the two support arms 313. The two ends of the transverse support rib 315 are connected to the two support arms 313 respectively, dividing the air pipe groove 317 into two parts. The transverse support rib 315 can improve the rigidity of the two support arms 313, thereby preventing the cantilever 31 from tilting relative to the horizontal plane after rotation to the desired position.
[0055] More preferably, the sleeve 6 includes an externally threaded section 612 and a cylindrical outer surface section 611 arranged sequentially in the vertical direction. Correspondingly, the supporting rotating arm 3 is provided with a vertical through hole, which includes a corresponding connecting threaded hole 311 and a sleeve groove 312, both coaxially arranged. The externally threaded section 612 and the connecting threaded hole 311 are threadedly connected, and the cylindrical outer surface section 611 is clearance-fitted with the sleeve groove 312. More preferably, the cylindrical outer surface section 611 is provided with auxiliary holes 62 evenly distributed in the circumferential direction to facilitate the rotation of the sleeve 6.
[0056] Based on the threaded connection between the sleeve 6 and the support arm 3, this utility model can connect the processing table 2 and the cantilever 31 by setting multiple sets of composite vibration reduction structures 1, thereby improving the connection stability between the processing table 2 and the cantilever 31, achieving vibration reduction effect while leveling the processing platform 2.
[0057] Specifically, the sleeve 6 is threadedly connected to the connecting threaded hole 311 via the external threaded section 612, enabling adjustment of the relative position of the sleeve 6 and the supporting rotating arm 3. This positional change is then transmitted to the machining table 2 via the elastic damping head 5. The cylindrical outer surface section 611 and the sleeve groove 312 are in clearance fit and serve a guiding function. Multiple sets of composite damping structures allow for horizontal position adjustment of multiple machining tables 2, ensuring consistent horizontal parallelism and height across all tables. It is understood that, to achieve the leveling effect of a single machining table 2, it is preferable to use at least three composite damping structures 1 to connect one machining table 2 to the cantilever 31. Furthermore, it is understood that, since the locking screw 9 compresses the spring 7 with a certain preload and connects to the machining table 2, the spring 7 also ensures that the preload of the locking screw 9 remains constant when the sleeve 6 is rotated during leveling.
[0058] More preferably, to ensure a stable connection between the composite vibration damping structure 1 and the cantilever 31, and to prevent the leveling accuracy from being affected by the movement of the sleeve 6 after the processing table 2 has been leveled, a fixing member 4 is provided on the outside of the sleeve 6, and the sleeve 6 and the cantilever 31 are detachably connected. Figure 3 and Figure 4 As shown, the fastener 4 has a vertical clamping hole 41 and a slot 44 that communicates laterally with the clamping hole 41, forming a U-shaped structure; one side of the slot 44 has several vertical fixing holes 42 for detachable connection with the cantilever 31 by means of threaded connectors; the side of the slot 44 also has several transverse connecting holes 43 that pass through the slot 44, and the slot 44 divides the transverse connecting holes 43 into two sections, one section being a through hole and the other section being a threaded hole, so that the clamping hole 41 can be clamped by means of threaded connectors.
[0059] The fixing member 4 is fitted onto the outer cylindrical side section 611 of the sleeve 6 through the clamping hole 41. The top surface of the fixing member 4 contacts the supporting rotating arm 3, and its position is fixed by the fixing member connected to the cantilever 31 through the fixing hole 42. After the machining table 2 is leveled, the gap of the slot 44 is compressed by the threaded connector in the transverse connecting hole 43, so that the clamping hole 41 is in close contact with the outer cylindrical side section 611, ensuring that the sleeve 6 cannot rotate or move.
[0060] In a non-limiting embodiment shown in the attached figure, the supporting swing arm 3 is a centrally symmetrical structure with 8 or 4 cantilever arms 31 distributed around the circumference of the cantilever base 32. Each cantilever arm 31 is provided with three composite vibration damping structures 1 arranged in a triangular pattern and connected to the processing table 2. Preferably, the three composite vibration damping structures 1 are arranged in an isosceles triangle. More specifically, the three sets of vibration damping and leveling structures 1 are connected to one processing table 2 through three sets of threaded connection holes 311 and sleeve grooves 312, and the three sets of composite vibration damping structures 1 and the three sets of spherical grooves 21 and clamping threaded holes 24 at the bottom of the processing table 2 are in one-to-one contact and threaded connection. When the number of cantilever arms is 8, two cantilever arms 8 form a group, and each group of cantilever arms 8 is equally spaced around the circumference of the cantilever base 32; when the number of cantilever arms is 4, the four cantilever arms 8 are equally spaced around the circumference of the cantilever base 32.
[0061] The installation process of this utility model for a vibration-damping workbench used in rotary machining is as follows: First, the supporting rotating arm 3 is installed and fixed on the top of the rotary motor 10. Then, the fixing part 4 is fixed to the bottom of a cantilever 31 on the supporting rotating arm 3 through multiple fixing holes 42. The sleeve 6 is passed through the clamping hole 41 on the fixing part 4 and the sleeve groove 312 on the cantilever 31, and the external thread section 612 on the upper part of the sleeve 6 is threadedly connected to the connecting threaded hole 311 on the cantilever 31. Then, the elastic damping head 5 is placed in the damping groove 61, and then the spring 7 and the washer 8 are placed in the spring groove 64, ensuring that the washer 8 is below the spring 7. Then, the locking screw 9 is passed through the washer 8, the spring 7, the through hole 63 and the elastic damping head 5 in sequence, and threadedly connected through the thread and the clamping threaded hole 24. Finally, the sleeve 6 is clamped and fixed through the connecting hole 43 and the screw.
[0062] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
