[0002] A cutting fixture is a device used to cut materials, primarily to improve cutting efficiency and quality. A cutting fixture typically includes a base plate, limiting devices, and cutting blades, designed to hold and cut various materials, such as silicone strips and mesh fabric. Through precise design and adjustable components, the cutting fixture can adapt to materials of different sizes and shapes, ensuring cutting accuracy and efficiency.

[0003] Conventional cutting fixtures, when fixing materials, may affect the surface of different materials due to the material of their limiting structure, thus affecting the processing quality of the materials.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a cutting tool. Utility Model Content

[0005] The purpose of this invention is to provide a cutting fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting fixture, comprising a base and a limiting assembly, wherein a negative pressure adsorption platform is installed in the middle of the base, and a first adjustment group is symmetrically arranged on the left and right sides of the negative pressure adsorption platform, and a second adjustment group is connected to the surface of the first adjustment group; the limiting assembly is symmetrically installed at the left and right ends of the second adjustment group; a gantry frame is mounted in the middle of the top of the base, and guide columns are vertically installed on the left and right sides of the gantry frame; and a cutting assembly is installed in the middle of the gantry frame; the limiting assembly comprises a stabilizing frame, a movable seat, a screw, a connecting frame, and a limiting plate; a movable seat is connected to one bottom side of the stabilizing frame, and a screw is vertically threaded through the side of the stabilizing frame away from the movable seat; a connecting frame is connected to the bottom of the screw, and a limiting plate is installed at the bottom of the connecting frame by bolts.

[0007] Furthermore, the first adjustment group is symmetrically installed on one side of the negative pressure adsorption platform, and the first adjustment group adopts a sunken structure and is installed on the left and right edges of the platform.

[0008] Furthermore, the first adjustment group includes a first servo motor, a drive screw, and a first guide rail. The power output end of the first servo motor is equipped with a drive screw via a coupling, and the first guide rail is horizontally installed on both sides of the drive screw.

[0009] Furthermore, the second adjustment group includes a moving beam, a second servo motor, a bidirectional lead screw, and a second guide rail. The second servo motor is installed at one end of the moving beam, and the power output end of the second servo motor is connected to the bidirectional lead screw via a coupling. The second guide rail is horizontally installed on both sides of the bidirectional lead screw.

[0010] Furthermore, the bottom left and right ends of the moving beam are respectively threaded and slidably connected to the drive screw and the first guide rail, and the second adjustment group is symmetrically arranged on the front and rear sides of the negative pressure adsorption platform.

[0011] Furthermore, the bottom of the movable seat is connected to the bidirectional lead screw and the second guide rail by threads and sliding connections respectively, and the stabilizer and the movable seat are fixedly connected.

[0012] Furthermore, the cutting assembly includes a base plate, a cutting tool, a hydraulic push rod, and guide posts. The cutting tool is installed at the bottom of the base plate, and the hydraulic push rod is vertically installed at the left and right ends of the top of the base plate. Guide posts are connected to both sides of the base plate.

[0013] Furthermore, the guide post is vertically inserted through the center of the guide pile and is slidably connected to each other, and the base plate and the guide pile are welded together.

[0014] This utility model provides a cutting fixture, which has the following beneficial effects:

[0015] 1. This utility model features a connecting frame installed at the bottom of the screw. Since the limiting plates are connected and fixed to the connecting frame with bolts, they are structurally disassembleable. This allows for the replacement of suitable limiting plates depending on the material being cut. The screw is then vertically turned so that the limiting plates connected to the connecting frame at its bottom are pressed against the top surface of the material, thus limiting the material in four positions to ensure cutting stability. Simultaneously, the operation of the negative pressure adsorption table effectively limits the material being cut, preventing unnecessary offset and misalignment during cutting. Furthermore, guide columns are vertically installed on both sides of the gantry frame, and the entire cutting assembly is slidably connected to the bidirectional screw via guide posts on both sides of the base plate. Therefore, under the operation of the hydraulic push rod, the cutter connected to the base plate at its bottom is pushed vertically, ensuring the lateral stability of the cutter's movement and guaranteeing cutting effectiveness, preventing incomplete cutting.

[0016] 2. This utility model features a first adjustment group symmetrically installed on the left and right sides of the platform. A first servo motor drives a drive screw connected to it to rotate horizontally, allowing the entire second adjustment group, connected to it via a moving beam, to move horizontally back and forth across the surface of the negative pressure adsorption platform. Meanwhile, a second servo motor on one side of the moving beam drives a bidirectional screw connected to it to rotate horizontally, allowing a limiting component connected to it via a moving seat to move left and right across both ends of the second adjustment group. By utilizing the above structure in conjunction with the adjustability of the limiting component, adjustments can be made within a certain range according to the size of the material, thereby limiting and fixing the material. This ensures both the stability of the material during cutting and the flexibility of the device structure. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 4As shown, a cutting fixture includes a base 1 and a limiting component 5. A negative pressure adsorption platform 2 is installed in the middle of the base 1, and first adjustment groups 3 are symmetrically arranged on the left and right sides of the negative pressure adsorption platform 2. A second adjustment group 4 is connected to the surface of the first adjustment group 3. The limiting component 5 is symmetrically installed at the left and right ends of the second adjustment group 4. A gantry frame 6 is supported in the middle of the top of the base 1, and guide columns 7 are vertically installed on the left and right sides of the gantry frame 6. A cutting component 8 is installed in the middle of the gantry frame 6. The limiting component 5 includes... The system includes a stabilizer 501, a movable base 502, a screw 503, a connecting frame 504, and a limiting plate 505. The movable base 502 is connected to one bottom side of the stabilizer 501, and the screw 503 is threaded vertically through the side of the stabilizer 501 away from the movable base 502. The bottom of the screw 503 is connected to the connecting frame 504, and the limiting plate 505 is bolted to the bottom of the connecting frame 504. The bottom of the movable base 502 is perpendicular to the bidirectional lead screw 403 and the second guide rail 404. The cutting assembly 8 includes a base plate 801, a cutter 802, a hydraulic push rod 803, and guide posts 804. The cutter 802 is mounted on the bottom of the base plate 801, and the hydraulic push rod 803 is vertically mounted on the left and right ends of the top of the base plate 801. Guide posts 804 are connected to both sides of the base plate 801. Guide posts 7 vertically penetrate the center of the guide posts 804 and are slidably connected to each other. The guide pile 804 is welded together. A connecting frame 504 is installed at the bottom of the screw 503. Since the limiting plate 505 is connected and fixed to the connecting frame 504 with bolts, they are structurally disassembled. The limiting plate 505 can be replaced according to the different materials being cut. Then, by vertically turning the screw 503, the limiting plate 505 connected to the bottom of the connecting frame 504 is pressed against the top surface of the material, thereby limiting the material in four positions.

[0024] like Figures 1 to 4As shown, the first adjustment group 3 is symmetrically installed on one side of the negative pressure adsorption platform 2, and the first adjustment group 3 adopts a sunken structure and is installed on the left and right edges of the platform 1. The first adjustment group 3 includes a first servo motor 301, a drive screw 302, and a first guide rail 303. The power output end of the first servo motor 301 is equipped with the drive screw 302 through a coupling, and the first guide rail 303 is horizontally installed on both sides of the drive screw 302. The second adjustment group 4 includes a moving beam 401, a second servo motor 402, a bidirectional screw 403, and a second guide rail 404. The second servo motor 402 is installed at one end of the moving beam 401, and the bidirectional screw 403 is installed at the power output end of the second servo motor 402 through a coupling. The second guide rails 404 are horizontally installed on both sides of the 03. The bottom left and right ends of the moving beam 401 are threaded and slidably connected to the drive screw 302 and the first guide rail 303, respectively. The second adjustment group 4 is symmetrically arranged on the front and rear sides of the negative pressure adsorption table 2. The first servo motor 301 drives the drive screw 302 connected to it to rotate horizontally, so that the entire second adjustment group 4 connected to it by the moving beam 401 can move horizontally back and forth on the surface of the negative pressure adsorption table 2. The second servo motor 402 on one side of the moving beam 401 drives the bidirectional screw 403 connected to it to rotate horizontally, so that the limiting component 5 connected to it by the moving seat 502 can move left and right at both ends of the second adjustment group 4.

[0025] In summary, as Figures 1 to 4 As shown, when using this cutting fixture, the material is first placed on the top surface of the negative pressure adsorption table 2 in the middle of the base 1. The negative pressure adsorption table 2 is used to adsorb the material to be cut to ensure its stability. Then, the first adjustment group 3 and the second adjustment group 4 are started at the same time. Under the operation of the first servo motor 301, the drive screw 302 connected to its power output end is driven to rotate axially in the horizontal direction. This allows the entire second adjustment group 4, which is connected to the drive screw 302 and the first guide rail 303 by the moving beam 401, to move horizontally back and forth along the surface of the drive screw 302 and the first guide rail 303. At the same time, the second servo motor 402 on one side of the moving beam 401 will operate synchronously and drive the bidirectional screw 403 connected to its power output end to rotate axially in the horizontal direction. This allows the limiting component 5 connected to the moving seat 502 to move left and right along the two ends of the bidirectional screw 403 and the second guide rail 404 respectively, so as to quickly adjust according to the structural dimensions of the material to be cut.

[0026] Once adjusted, simply tighten the screw 503 at one end of the stabilizer 501. This will cause the bottom of the screw 503, which is connected and fixed by the connecting frame 504, to press against the top surface of the material, thus structurally limiting the material. Then, start the cutting assembly 8 installed in the middle of the gantry 6. With the operation of the hydraulic push rod 803, the cutter 802, which is fixedly installed at its bottom by the base plate 801, will be pushed vertically downward. At the same time, the guide posts 804 on both sides of the base plate 801 will slide along the surface of the guide post 7, thereby ensuring the smooth movement of the cutter 802 for accurate and effective cutting.

[0027] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
