Description

Technical Field

[0001] This utility model relates to the field of positioning mechanism technology, specifically a positioning mechanism for cutting sculpture materials. Background Technology

[0002] In wooden sculpture art creation and model making, sculpture boards (such as linden boards, nanmu boards, walnut boards, etc.) are extremely commonly used base materials. Compared with heavy, large-sized solid wood or stone, these sculpture boards have a significant characteristic: they are lightweight and have a relatively loose texture. This characteristic brings unique challenges during processing. First, due to the light weight of the boards, their "natural stability" on the workbench is very poor. Under the high-speed rotation or reciprocating impact of cutting tools (such as band saws, wire saws, carving knives), they are prone to overall displacement, jumping, or strong vibration. This not only leads to inaccurate cutting dimensions, chipped or rough cut surfaces, seriously affecting processing accuracy and yield, but also poses a safety hazard due to the boards accidentally flying off. In existing technologies, operators position the boards by hand, but the stability is poor. Alternatively, clamps are used to fix the boards, but multiple clamps need to be operated, which is cumbersome. Furthermore, because the clamps are fixed in position, they cannot be used for boards of different lengths, resulting in poor versatility. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a cutting and positioning mechanism that is highly versatile, can reduce operations, and ensures stable cutting of sculpture materials.

[0004] The technical solution adopted by this utility model to achieve the above-mentioned objectives is as follows: a sculpture material cutting and positioning mechanism, including a base, a fixed platform, a moving platform, and clamping components. The fixed platform is fixedly connected to the base, and the moving platform is slidably connected to the base. A traction component is provided on the base in conjunction with the moving platform. The traction component is in conjunction with a driving component A, which can provide power to the traction component, causing the traction component to pull the moving platform to slide linearly. The clamping components are fixedly connected to both the moving platform and the fixed platform. Both sets of clamping components are in conjunction with driving components B, which can simultaneously provide power to both sets of clamping components, so that the two sets of clamping components achieve a synchronous clamping effect.

[0005] In the above technical solution, the traction component adopts the following structure: The traction component includes a lead screw A, a lead screw sleeve A, and an input shaft A. The lead screw sleeve A is fixedly connected to the motion machine platform. The lead screw A is fitted with the lead screw sleeve A. One end of the lead screw A is fixedly connected to the input shaft A. The input shaft A is poweredly connected to the drive component A. When the drive component A transmits power to the lead screw A, the motion machine can slide linearly on the base.

[0006] In the above technical solution, the driving component A adopts the following structure: The driving component A includes a worm A, a worm wheel A, an operating disk A, and an operating shaft. The worm wheel A is fixedly connected to the input shaft, and the worm A is rotatably connected to the base. The worm A is meshed with the worm wheel A. The operating shaft is fixedly connected to the worm A and rotatably connected to the base. One end of the operating shaft is fixedly connected to the operating disk A. When the operating disk A is rotated, the worm gear A is driven to rotate, which in turn drives the worm wheel A to rotate. At this time, the lead screw A can rotate, thus realizing the operation of the traction component.

[0007] In the above technical solution, the clamping component adopts the following structure: The clamping component includes a frame, a clamping base, a clamping top, and a linear motion module. The frame is fixedly connected to both the fixed frame and the moving frame. The clamping base is fixedly connected to each set of frames. The linear motion module includes a moving table. The clamping top is fixedly connected to the moving table. The clamping top corresponds to the clamping base. Both sets of linear motion modules are powered by the drive component B. When the drive component B transmits power to the two sets of linear motion modules, the motion table can drive the clamping top platform to move towards the clamping bottom platform, and the material is clamped and fixed by the clamping top platform and the clamping bottom platform.

[0008] In the above technical solution, the linear motion module adopts the following structure: The linear motion module includes a guide column, a lead screw B, and an input shaft B. The guide column is fixedly connected to the frame, and the motion table is slidably connected to the guide column. A lead screw sleeve B is fixedly connected to the motion table, and the lead screw B cooperates with the lead screw sleeve B. One end of the lead screw B is fixedly connected to the input shaft B. Both sets of input shafts B are poweredly connected to the drive component B. When the drive component B transmits power to the two sets of input shafts B, the two sets of lead screws B can rotate simultaneously, so that the two sets of motion tables can move linearly along the guide column synchronously.

[0009] In the above technical solution, the driving component B adopts the following structure: The drive component B includes a worm B, a worm wheel B, a spline shaft, a spline sleeve, and an operation disk B. Each set of input shafts B is fixedly connected to the worm wheel B. The fixed machine base and the moving machine base are rotatably connected to the worm B. The worm B is meshed with the corresponding worm wheel B. Each set of worm gears B has a bevel gear A fixedly connected to one end. The spline sleeve is rotatably connected to the motion machine base. The spline shaft is rotatably connected to the fixed machine base. Bevel gears B are fixedly connected to both the spline sleeve and the spline shaft. The bevel gear A meshes with the corresponding bevel gear B. The spline sleeve is provided with a spline hole, and the spline shaft is inserted into the spline hole; One end of the spline shaft is fixedly connected to the operation disk B. When the operation disk B is rotated, the spline shaft can drive the spline sleeve to rotate synchronously. Then, under the action of the bevel gear A and bevel gear B, the power can be synchronously transmitted to the input shaft B to realize the operation of the linear motion module.

[0010] The beneficial effects of this utility model are: 1. The traction component can drive the motion machine to move in a straight line, thereby causing the two sets of clamping components to move closer or further apart, thus clamping and fixing sculpture materials of different lengths, greatly enhancing the versatility of the equipment; 2. Two sets of clamping components can clamp and fix both ends of the sculpture material to prevent vibration or displacement during cutting and ensure the stability of material cutting; 3. Through the operation panel B, the power is synchronously transmitted to the two clamping components on the fixed machine table and the moving machine table via the combination of spline shaft, spline sleeve and bevel gear. This ensures that both ends of the material are clamped at the same time and with the same force, reducing the operation time and avoiding material displacement or stress deformation caused by clamping one side first.

Detailed Implementation

[0013] 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.

[0014] Please see Figures 1-6 This invention provides a sculpting material cutting and positioning mechanism, which is particularly suitable for fixing lightweight and easily vibrating wooden sculpting boards to ensure their stability during the cutting process; The mechanism comprises a base 100, a fixed platform 200, a moving platform 300, and a clamping component 400. The base 100 serves as the fundamental support platform for the entire mechanism and is placed horizontally. The fixed platform 200 is fixedly mounted on one end of the base 100. The moving platform 300 is slidably connected to the base 100 via linear guide posts and is located on the opposite side of the fixed platform 200, allowing the moving platform 300 to move linearly closer to or further away from the fixed platform 200. In order to precisely control the movement of the motion machine 300, the mechanism is provided with a traction component and its driving component A. The traction component includes a lead screw A501, a lead screw sleeve A and an input shaft A. The lead screw sleeve A is fixedly installed at the bottom of the motion machine 300. The lead screw A501 and the lead screw sleeve A form a helical pair. One end of the lead screw A501 is fixedly connected to the input shaft A. The drive component A is used to provide power to the traction component. It includes a worm A601, a worm wheel A602, an operating shaft 603, and an operating disc A604. The worm wheel A602 is fixedly sleeved on the input shaft A. The worm A601 is rotatably supported on the base 100 by bearings and meshes with the worm wheel A602. The operating shaft 603 is fixedly connected to the worm A601 and is also supported on the base 100 by bearings. The operating disc A604 is fixedly installed on its outer end. When the operator rotates the control panel A604, the power is transmitted sequentially to the input shaft A through the worm gear A601 and worm wheel A602, driving the lead screw A501 to rotate. Since the lead screw sleeve A is fixed to the motion machine 300 and the axial direction of the lead screw A501 is constrained, according to the principle of screw transmission, the rotating lead screw A501 will drive the lead screw sleeve A, together with the entire motion machine 300, to move precisely and smoothly in a straight line along the base 100, thereby adjusting the distance between the fixed machine 200 and the motion machine 300 to accommodate sculpture plates of different lengths. The inherent self-locking characteristics of the worm gear mechanism can effectively prevent the motion machine 300 from undergoing unexpected displacement during cutting vibration. Furthermore, above both the fixed machine platform 200 and the moving machine platform 300, there is a set of clamping components 400 for clamping the sculpture board. Each set of clamping components 400 includes a frame 401, a clamping base 402, a clamping top 403, and a linear motion module 404. The frame 401 is fixedly installed on its respective machine base, the clamping base 402 is fixedly installed on the bottom of the frame 401, the linear motion module 404 is installed on the frame 401, which includes a motion table 4044 that can move vertically up and down, and the clamping top table 403 is fixedly installed on the motion table 4044 and precisely aligned with the clamping base 402 below. The linear motion module 404 has a specific structure including a vertically fixed guide column 4041, a lead screw B4042, and an input shaft B4043. The motion table 4044 is slidably sleeved on the guide column 4041 through a linear bearing, thereby ensuring the vertical accuracy of the motion table 4044 and preventing wobbling. A lead screw sleeve B is fixedly installed on the motion table 4044. The lead screw B4042 and the lead screw sleeve B form a helical pair. One end of the lead screw B4042 is fixedly connected to the input shaft B4043. When the input shaft B4043 is driven to rotate, it will drive the lead screw B4042 to rotate, thereby driving the motion table 4044 together with the clamping top table 403 to perform precise vertical lifting and lowering movements along the guide column 4041. To ensure that both ends of the sculpture board are clamped simultaneously, synchronously and evenly, and to avoid warping or displacement of the lightweight board due to unilateral force, the linear motion modules 404 of the two sets of clamping components 400 are synchronously driven by a common drive component B. Furthermore, the drive component B includes a worm gear B701, a worm wheel B702, a splined shaft 703, a splined sleeve 704, and an operating panel B705. That is, a worm wheel B702 is fixedly installed on the input shaft B4043 of each linear motion module 404. On the fixed machine base 200 and the moving machine base 300, a worm gear B701 is rotatably installed through bearings, and each worm gear B701 meshes with the worm wheel B702 on the same machine base. Each worm gear B701 has a bevel gear A706 fixedly installed at one end; A spline sleeve 704 is rotatably mounted on the motion machine 300 via bearings, and a spline shaft 703 is rotatably mounted on the fixed machine 200 via bearings. A bevel gear B707 is fixedly mounted on one end of the spline sleeve 704 and one end of the spline shaft 703. The bevel gear B707 meshes with the corresponding bevel gear A706. The spline shaft 703 is inserted into the spline hole of the spline sleeve 704, so that the spline shaft 703 and the spline sleeve 704 can transmit torque, while allowing the two to have relative sliding displacement in the axial direction. Furthermore, an operation panel B705 is fixedly mounted on the outer end of the spline shaft 703; When the operator rotates the control panel B705, power is transmitted to the splined sleeve 704 through the splined shaft 703, achieving synchronous rotation of both. Subsequently, the power is transmitted to the worm gears B701 on the fixed machine base 200 and the moving machine base 300 through two pairs of meshing bevel gears B707 and A706, respectively. The worm gears B701 then drive their corresponding worm wheels B702 and input shafts B4043 to rotate synchronously. Finally, the two lead screws B4042 rotate synchronously, driving the two clamping top platforms 403 to move vertically downward at the same speed and force, working in conjunction with their respective clamping bottom platforms 402 to firmly clamp both ends of the sculpture board at the same time. During this process, the worm gear mechanism once again provides reliable self-locking capability, ensuring that the clamping force will not loosen under cutting vibration. In practice, the shapes of the clamping top platform 403 and the clamping bottom platform 402 can be set according to the actual situation to ensure that the two can stably clamp the sculpture material. In another implementation, to reduce manpower, both the aforementioned control panel A604 and control panel B705 can be replaced with motors to achieve electric drive.

[0015] The working principle of this embodiment is as follows: In use, first rotate the operation disk A604 to adjust the position of the motion stage 300, place the sculpture board to be processed on the clamping base 402 of the fixed stage 200 and the motion stage 300, and then rotate the operation disk B705 to synchronously drive the clamping top stages 403 at both ends to descend, pressing the board smoothly and firmly onto the clamping base 402. Due to the synchronous transmission design of the drive component B, the force on both ends of the board is completely synchronous and uniform, effectively preventing the warping and stress concentration of the lightweight board. After clamping, the entire board, the stage and the base 100 form a rigid system, which is sufficient to overcome its light weight and resist various forces during the cutting process, thereby achieving high-precision cutting processing.
