Description

Technical Field

[0001] This utility model relates to the technical field of equipment for sculpture processing, specifically a blank placement platform for sculpture processing. Background Technology

[0002] In the creation and processing of sculptures, fixing and adjusting the posture of the blank are crucial steps affecting processing accuracy and operational efficiency. Traditional blank placement tables often use simple fixed platforms or manually adjustable clamps, which are difficult to adapt to the irregular shapes and varying sizes of sculpture blanks. Especially for large or complex-shaped blanks, conventional clamps often cannot achieve uniform and stable clamping, causing the blank to shift or wobble during carving, seriously affecting processing quality, and may even cause material damage or safety accidents.

[0003] In existing technologies, some placement tables attempt to fix the billet using multiple clamping mechanisms. However, since most clamps use a synchronous contraction method, they cannot make local fine adjustments for the irregular contours of the billet, resulting in some clamping points failing to effectively contact the billet surface and uneven distribution of clamping force. In addition, traditional placement tables usually lack circumferential adjustment functions, requiring frequent manual movement or rotation of the billet during processing, which not only increases labor intensity but also reduces processing consistency and accuracy. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a blank placement platform for sculpting processing, so as to solve the problems of poor clamping adaptability, insufficient adjustment accuracy and low system integration in the existing technology.

[0005] The technical solution adopted by this utility model to achieve the above-mentioned objective is: a blank placement platform for sculpting processing, including a mounting base and a rotating platform rotatably mounted on the top of the mounting base, and also including multiple sets of clamping components assembled on the rotating platform and distributed in a circular array, each set of clamping components synchronously extending and retracting along the radial direction of the rotating platform.

[0006] Each clamping assembly includes a guide bracket, a guide sleeve, a telescopic rod, a clamping seat, and a fine-tuning mechanism. The guide bracket is slidably installed on the outer wall of the rotating platform and moves radially along the rotating platform. The guide sleeve is fixedly connected to the outer end of the guide bracket and arranged on the platform surface of the rotating platform. The telescopic rod is slidably installed in the guide sleeve. The fine-tuning mechanism is assembled in the guide sleeve and maintains a dynamic connection with the telescopic rod. The clamping seat is fixedly connected to the end of the telescopic rod.

[0007] It also includes adjustment component A and adjustment component B assembled into the mounting base. Adjustment component A is poweredly connected to the rotating table, and adjustment component B is poweredly connected to the guide bracket in each of the clamping components.

[0008] Based on the above technical solutions, in order to ensure that the rotary table and adjustment component A can be stably assembled on the mounting base, and to achieve precise adjustment of the rotary table through adjustment component A, the following technical solutions are provided.

[0009] The mounting base has a mounting cavity, and the top of the mounting cavity is provided with a mounting partition. The rotating platform has a receiving cavity, which is arranged on the mounting partition.

[0010] The adjustment component A includes a drive motor, a sun gear, planet gears, and an internal gear ring. The internal gear ring is fixed to the inner wall of the accommodating cavity. The sun gear and planet gears are rotatably mounted on the mounting partition. The planet gears include multiple sets arranged in a circular array around the sun gear. Each set of planet gears is engaged with the sun gear and the internal gear ring. The drive motor is fixedly mounted in the mounting cavity and is poweredly connected to the sun gear.

[0011] Based on the above technical solutions, in order to ensure that the adjustment component B can be stably assembled in the mounting base and to realize the synchronous retraction and adjustment of each clamping component, the following technical solutions are provided.

[0012] An installation sleeve is fixedly connected to the center of the mounting cavity, and a transmission sleeve arranged above the installation sleeve is fixedly connected to the center of the sun gear.

[0013] The adjustment component B includes a telescopic electric cylinder, a connecting shaft, a ring seat, and connecting rods. The telescopic electric cylinder is fixedly installed in the mounting sleeve and coaxially connected to the connecting shaft. The connecting shaft is slidably inserted into the mounting sleeve. The connecting shaft passes through the transmission sleeve and extends into the receiving cavity. The ring seat is rotatably installed on the top end of the connecting shaft. Multiple sets of connecting rods are hinged to the periphery of the ring seat. Each set of connecting rods is hinged to the inner end of the guide bracket at the corresponding position.

[0014] Based on the above technical solution, in order to ensure that the drive motor can achieve power connection with the sun gear and avoid mutual interference with the adjustment component B, the following technical solution is provided.

[0015] A transmission bevel gear is fixedly connected to the transmission sleeve and arranged in the mounting cavity. A drive bevel gear is fixedly connected to the output shaft of the drive motor. The drive bevel gear and the transmission bevel gear are engaged.

[0016] Based on the above technical solutions, in order to ensure that the fine-tuning mechanism can be stably assembled in the guide sleeve and to achieve independent adjustment of the extension and retraction posture of the corresponding telescopic rod, the following technical solutions are provided.

[0017] The fine-tuning mechanism includes a threaded rod and a matching combination of a worm gear and a worm. The threaded rod is fixed to the end of the telescopic rod and arranged in the guide sleeve. The worm gear and the worm are rotatably installed in the guide sleeve. The axial position of the threaded rod and the worm gear remains screwed together. A handwheel arranged on the outside of the guide sleeve is fixed to the end of the worm.

[0018] The beneficial effects of this utility model are: 1. By setting up multiple sets of independently adjustable clamping components, the problem of poor adaptability of traditional synchronous clamps to irregularly shaped blanks is overcome. The clamping components first achieve synchronous radial contraction by adjusting component B, completing the initial positioning and basic clamping of the blank; then, for clamping points that are not in close contact with the blank, the fine adjustment mechanism is used to independently fine adjust the corresponding telescopic rods and clamping seats, so that all clamping points can effectively fit the outer contour of the blank, significantly improving the stability and adaptability of clamping, and is particularly suitable for sculptural blanks with complex and varied shapes.

[0019] 2. By connecting the rotary table to the planetary reduction mechanism of the adjusting component A, the smooth and precise rotation of the workpiece around its own axis is achieved. The drive motor drives the sun gear to rotate via a bevel gear set, and transmits power to the rotary table through the meshing of the planetary gears and the internal gear ring. This transmission structure is compact, has a strong load-bearing capacity, and a large transmission ratio, enabling precise angle control of the rotary table and workpiece under high load conditions. This facilitates omnidirectional sculpting of the workpiece, effectively improving processing efficiency and operational convenience.

[0020] 3. By arranging the drive motor of adjustment component A laterally and using bevel gears for vertical reversal, the movement path of adjustment component B (telescopic electric cylinder, connecting shaft, etc.) located at the axis is cleverly avoided. Simultaneously, the ring seat and connecting shaft are rotatably connected, ensuring that the clamping component does not interfere with the lifting and lowering adjustment component B when it revolves with the rotary table. This compact and rational spatial layout ensures that the radial clamping adjustment and circumferential rotation adjustment functions operate independently and collaboratively, improving the reliability and integration of the equipment.

[0021] 4. The fine-tuning mechanism in the clamping assembly adopts a combination of worm gear and threaded rod. This structure not only accurately converts the rotation of the handwheel into the linear displacement of the telescopic rod for fine-tuning, but also utilizes the one-way self-locking characteristic of the worm gear and worm drive to automatically lock the position of the telescopic rod after adjustment. This effectively prevents the clamping force from loosening under processing vibration, ensuring that the workpiece remains in a stable and reliable clamping state throughout the entire processing, thus guaranteeing processing safety and quality.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 A blank placement platform for sculpting includes a mounting base 1 and a rotating platform 2 rotatably mounted on the top of the mounting base 1. It also includes multiple sets of clamping components 3 assembled on the rotating platform 2 and arranged in a circular array. Each set of clamping components 3 moves synchronously in the radial direction of the rotating platform 2.

[0026] Each clamping assembly 3 includes a guide bracket 31, a guide sleeve 32, a telescopic rod 33, a clamping seat 34, and a fine-tuning mechanism 35. The guide bracket 31 is slidably installed on the outer wall of the rotating table 2 and moves radially along the rotating table 2. The guide sleeve 32 is fixed to the outer end of the guide bracket 31 and arranged on the table surface of the rotating table 2. The telescopic rod 33 is slidably installed in the guide sleeve 32. The fine-tuning mechanism 35 is assembled in the guide sleeve 32 and maintains a power connection with the telescopic rod 33. The clamping seat 34 is fixed to the end of the telescopic rod 33.

[0027] It also includes adjustment components A4 and B5 assembled into the mounting base 1. Adjustment component A4 is powered to the rotating table 2, and adjustment component B5 is powered to the guide bracket 31 in each set of clamping components 3.

[0028] The mounting base 1 and the rotating platform 2 are arranged coaxially. The mounting base 1 can provide stable support and a support carrier for the stable installation and operation of the components involved. It has good load-bearing capacity and ensures that the rotating platform 2 is stably assembled and operated on it.

[0029] The rotating table 2 is used to support the blank to be sculpted. The bottom of the blank is effectively clamped by the clamping component 3 to achieve precise positioning of the blank, thereby ensuring the stability of the sculpting process. When the rotating table 2 is driven by the adjusting component A4, it can drive the blank to rotate synchronously around its own axis, realizing the circumferential posture adjustment of the blank to facilitate the sculpting operation.

[0030] Since the outer contour of the billet is not a standard regular shape, traditional synchronous shrinkage adjustment clamps cannot effectively position the bottom of the billet. For the clamping assembly 3 provided in this solution, the guide bracket 31 in each set of clamping assemblies 3 firstly shrinks synchronously by adjusting assembly B5, thereby causing the clamping seat 34 mounted on it to expand and contract synchronously, so as to achieve initial positioning of the billet. At this time, the clamping seat 34 in some clamping assemblies 3 will be in close contact with the billet to clamp the billet. The other clamping assemblies 3 that do not clamp the billet can be further individually adjusted by operating the fine adjustment mechanism 35 on them to effectively clamp the clamping seat 34 to the billet.

[0031] To ensure that the rotating table 2 and the adjustment component A4 can be stably assembled on the mounting base 1, and to achieve precise adjustment of the rotating table 2 through the adjustment component A4, the following technical solution is provided.

[0032] The mounting base 1 has a mounting cavity 11, and the top of the mounting cavity 11 is provided with a mounting partition 12. The rotating table 2 has a receiving cavity 21, which is arranged on the mounting partition 12.

[0033] The adjustment assembly A4 includes a drive motor 41, a sun gear 42, planet gears 43, and an internal gear ring 44. The internal gear ring 44 is fixed to the inner wall of the accommodating cavity 21. The sun gear 42 and planet gears 43 are rotatably mounted on the mounting partition 12. The planet gears 43 include multiple sets arranged in a ring array around the sun gear 42. Each set of planet gears 43 is meshed with the sun gear 42 and the internal gear ring 44. The drive motor 41 is fixedly mounted in the mounting cavity 11 and is poweredly connected to the sun gear 42.

[0034] The mounting partition 12 is fixedly installed on the mounting cavity 11 in a detachable manner, which facilitates the assembly of various components involved in the mounting cavity 11. The mounting partition 12 ensures that the sun gear 42 and planet gear 43 are stably installed on it in a relative rotational manner. When the drive motor 41 drives the sun gear 42 to run stably, the planetary reduction mechanism composed of the sun gear 42, planet gear 43 and internal gear ring 44 can reduce the output power of the adjustment motor and increase the torque, thereby making the internal gear ring 44 and the rotating table 2 fixed to it run stably, so as to achieve precise adjustment of the circumferential posture of the billet.

[0035] To ensure that the adjustment component B5 can be stably assembled in the mounting base 1 and to achieve synchronous retraction and adjustment of each clamping component 3, the following technical solution is provided.

[0036] A mounting sleeve 13 is fixedly connected to the shaft center of the mounting cavity 11, and a transmission sleeve 421 arranged above the mounting sleeve 13 is fixedly connected to the shaft center of the sun gear 42.

[0037] The adjustment assembly B5 includes a telescopic electric cylinder 51, a connecting shaft 52, a ring seat 53, and a connecting rod 54. The telescopic electric cylinder 51 is fixedly installed in the mounting sleeve 13 and coaxially fixed to the connecting shaft 52. The connecting shaft 52 is slidably inserted into the mounting sleeve 13. The connecting shaft 52 passes through the transmission sleeve 421 and extends into the receiving cavity 21. The ring seat 53 is rotatably installed on the top of the connecting shaft 52. Multiple sets of connecting rods 54 are hinged to the periphery of the ring seat 53. Each set of connecting rods 54 is hinged to the inner end of the guide bracket 31 at the corresponding position.

[0038] The mounting sleeve 13 ensures that the telescopic electric cylinder 51 is stably assembled in the mounting cavity 11, and at the same time provides guidance for the lifting and lowering movement of the connecting shaft 52. The transmission sleeve 421 is hollow inside, which ensures that the connecting shaft 52 extends into the receiving cavity 21, so as to avoid the presence of the sun gear 42 causing spatial movement interference to the connecting shaft 52. Then, the combination of the ring seat 53 and the connecting rod 54 realizes the power connection with each set of clamping components 3.

[0039] The ring seat 53 is linked with each clamping component 3 through various sets of connecting rods 54. Since the ring seat 53 is rotatably connected to the connecting shaft 52, when the ring seat 53 and connecting rods 54 move synchronously with the rotating table 2 and the clamping components 3 on it, there will be no spatial movement interference to the connecting shaft 52. During the process of the telescopic electric cylinder 51 driving the connecting shaft 52 and the ring seat 53 to move up and down, the corresponding clamping components 3 can be synchronously adjusted for retraction and extension through each set of connecting rods 54.

[0040] To ensure that the drive motor 41 can achieve power connection with the sun gear 42 and avoid mutual interference with the adjustment component B5, the following technical solution is provided.

[0041] A transmission bevel gear 422 arranged in the mounting cavity 11 is fixedly connected to the transmission sleeve 421, and a drive bevel gear 411 is fixedly connected to the output shaft of the drive motor 41. The drive bevel gear 411 and the transmission bevel gear 422 are engaged.

[0042] Since the telescopic electric cylinder 51 and the connecting shaft 52 are located in the axial direction of the transmission sleeve 421, the drive motor 41 cannot be arranged in this direction. Therefore, the drive motor 41 is arranged horizontally and the vertical reversal of power transmission is achieved through the combination of two sets of bevel gears to drive the sun gear 42 to operate stably.

[0043] To ensure that the fine-tuning mechanism 35 can be stably assembled in the guide sleeve 32 and to achieve independent adjustment of the telescopic posture of the corresponding telescopic rod 33, the following technical solution is provided.

[0044] The fine-tuning mechanism 35 includes a threaded rod 351 and a matching combination of a worm gear 352 and a worm 353. The threaded rod 351 is fixed to the end of the telescopic rod 33 and arranged in the guide sleeve 32. The worm gear 352 and the worm 353 are rotatably installed in the guide sleeve 32. The axial position of the threaded rod 351 and the worm gear 352 is kept screwed together. The end of the worm 353 is fixed to a handwheel 354 arranged on the outside of the guide sleeve 32.

[0045] When it is necessary to independently fine-tune the position and attitude of the telescopic rod 33 and the clamp 34, the first wheel is operated to drive the worm 353 and worm wheel 352 to rotate stably. Under the action of the guide sleeve 32 to provide the telescopic rod 33 with telescopic movement along its own axis, the worm wheel 352 drives the threaded rod 351 and the telescopic rod 33 and clamp 34 fixed thereto to adjust the telescopic movement stably.

[0046] Because the combination of worm gear 352 and worm 353 has a one-way self-locking characteristic, after the worm 353 is adjusted, it can apply a one-way self-locking to the worm gear 352, preventing the worm gear 352 and the threaded rod 351 that it cooperates with from having an ineffective displacement, thereby ensuring that the clamping seat 34 applies a continuous clamping force to the blank.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
