Description

Technical Field

[0001] This application relates to cutting tools, and more particularly to a three-axis cutting tool. Background Technology

[0002] As a core tool in the manufacturing industry, cutting equipment is widely used in clothing, packaging, composite material processing and other fields. With the continuous improvement of the requirements of modern industry for processing accuracy and production efficiency, traditional single-axis or dual-axis cutting equipment has gradually exposed problems such as insufficient flexibility and large cutting blind spots when facing complex curved surfaces and multi-dimensional irregular parts.

[0003] Traditional cutting equipment suffers from poor mobility and struggles to achieve precise multi-directional displacement adjustment based on preset trajectories. During complex cutting operations, frequent adjustments to workpiece position or changes to the cutting blade are necessary, increasing operational complexity and increasing the risk of cutting accuracy deviations due to positioning errors. Furthermore, the exposed design of many moving parts allows debris and oil to easily penetrate the sliding components, accelerating guide rail wear. To address these issues, a three-axis cutting blade is proposed. Utility Model Content

[0004] The purpose of this application is to provide a three-axis cutting blade with advantages such as moving function and protection function, which solves the problems of insufficient flexibility of traditional cutting equipment in complex operations, cutting accuracy being easily affected by positioning errors, and the accelerated wear of guide rails due to the exposed design of the moving structure.

[0005] The three-axis cutting knife provided in this application adopts the following technical solution: it includes a housing, and a transverse moving box is fixedly connected to both sides of the housing. A first electric push rod is fixedly connected to the inner side of the transverse moving box. Sliding holes are opened on both sides of the transverse moving box, and a connecting moving box is slidably connected inside the sliding holes.

[0006] One end of the first electric push rod is fixedly connected to the side of the connecting movable box. A stepper motor is fixedly connected to the side of the connecting movable box. The output end of the stepper motor rotates through the side of the connecting movable box and is fixedly connected to a threaded rod. The shaft end of the threaded rod is rotatably connected to the inner side of the connecting movable box. A threaded cylinder is threadedly connected to the surface of the threaded rod. A movable block is fixedly connected to the surface of the threaded cylinder. Through holes are opened on opposite sides inside the connecting movable box. L-shaped connecting rods are fixedly connected to opposite sides of the movable block. The L-shaped connecting rods are slidably connected in the through holes. A base plate is fixedly connected to the bottom ends of the two L-shaped connecting rods. Multiple second electric push rods are fixedly connected to the top of the base plate. A mounting plate is fixedly connected to the top of the second electric push rods. A cutting blade body is mounted on the top of the mounting plate.

[0007] By adopting the above technical solution, the first electric push rod can drive the connecting moving box to move laterally along the sliding hole, thereby adjusting the lateral position of the cutting blade body. The stepper motor can drive the threaded rod to rotate, allowing the threaded cylinder and movable block to move on the surface of the threaded rod. The L-shaped connecting rod and the through hole can adjust the longitudinal position of the base plate and the cutting blade body. The second electric push rod can push the mounting plate and the cutting blade body to move vertically. Through the coordinated action of the three, the cutting blade body can move flexibly in three-dimensional space, meeting the needs of different cutting positions. At the same time, the sliding fit between the sliding hole and the connecting moving box, and the sliding connection between the through hole and the L-shaped connecting rod, provide stable guidance for lateral and longitudinal movement, ensuring smooth operation of the blade body during the cutting process.

[0008] Preferably, there are four second electric push rods, and the four second electric push rods are respectively set at the four corners of the top of the base plate;

[0009] By adopting the above technical solution, four second electric push rods are distributed at the four corners of the top of the base plate, which can provide uniform and stable support force from the four corners when pushing the mounting plate and the cutting blade body to rise and fall. This can avoid the mounting plate tilting and the cutting blade body shaking caused by single-point support or uneven force.

[0010] Preferably, the plurality of sliding holes are provided with a first annular frame, the through hole is provided with a second annular frame, the connecting movable box slides inside the plurality of first annular frames, and the L-shaped connecting rod slides in the second annular frame;

[0011] By adopting the above technical solution, and by setting the first annular frame and the second annular frame, it is possible to form a further enclosed limit on the lateral sliding of the connecting movable box in the sliding hole and the longitudinal sliding of the L-shaped connecting rod in the through hole.

[0012] Preferably, the first annular frame has a first annular contraction groove on its inner side, and the second annular frame has a second annular contraction groove on its inner side.

[0013] By adopting the above technical solution and setting the first annular shrinkage groove and the second annular shrinkage groove, storage space can be provided for subsequent dust-proofing equipment.

[0014] Preferably, a first folding plate is fixedly connected to both sides of the inside of the first annular shrinkage groove, and one side of each of the two first folding plates is fixedly connected to the opposite sides of the connecting movable box.

[0015] By adopting the above technical solution and setting the first folding plate, the connecting movable box can be unfolded or folded as it moves along the first annular frame when it slides laterally. Thus, the first folding plate can dynamically block the gap between the first annular frame and the connecting movable box, preventing external dust, debris and other impurities from entering the equipment through the sliding hole.

[0016] Preferably, two first sliding rods are fixedly connected to the inner side of the first annular shrinkage groove, and multiple first sliders are fixedly connected to the back of the first folding plate. The multiple first sliders are divided into two rows vertically and are all slidably connected to the back of the first sliding rods.

[0017] By adopting the above technical solution, by setting the first sliding rod and the first slider, a stable guiding support can be provided for the unfolding and folding of the first folding plate. When the connecting moving box drives the first folding plate to move, multiple first sliders will slide smoothly along the first sliding rod, so that the first folding plate maintains a neat shape during the unfolding process, which can avoid deviation and improve the blocking effect of gaps.

[0018] Preferably, a second folding plate is fixedly connected to both sides of the inside of the second annular shrinkage groove, and one side of each of the two second folding plates is fixedly connected to the opposite sides of the L-shaped connecting rod.

[0019] By adopting the above technical solution and setting the second folding plate, the L-shaped connecting rod can be opened or folded synchronously as it slides along the second annular frame. Thus, the two second folding plates can provide double dynamic shielding of the gap between the second annular frame and the L-shaped connecting rod from opposite sides, which can enhance the dustproof sealing of the equipment and prevent impurities from entering the equipment through the gap generated by the longitudinal sliding.

[0020] Preferably, two second slide rods are fixedly connected to the inner side of the second annular shrinkage groove, and multiple second sliders are fixedly connected to the back of the second folding plate. The multiple second sliders are divided into two rows vertically and are all slidably connected to the back of the second slide rods.

[0021] By adopting the above technical solution, and by setting the second slide bar and the second slider, a stable guide can be provided for the unfolding and folding of the second folding plate. When the L-shaped connecting rod drives the second folding plate to move, multiple second sliders slide smoothly along the second slide bar, which can ensure that the second folding plate is neatly shaped when unfolded and avoid deviation.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This three-axis cutting blade features a first electric push rod that drives a connecting movable box to move laterally along a sliding hole, thereby adjusting the lateral position of the cutting blade body. A stepper motor drives a threaded rod to rotate, allowing the threaded cylinder and movable block to move on the surface of the threaded rod. The L-shaped connecting rod, in conjunction with a through hole, allows for longitudinal position adjustment of the base plate and the cutting blade body. A second electric push rod pushes the mounting plate and the cutting blade body to move vertically. Through the coordinated action of these three components, the cutting blade body can move flexibly in three-dimensional space, meeting the needs of different cutting positions. Furthermore, the sliding fit between the sliding hole and the connecting movable box, and the sliding connection between the through hole and the L-shaped connecting rod, provide stable guidance for lateral and longitudinal movement, ensuring smooth blade operation during the cutting process.

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail below.

[0033] Example 1: A three-axis cutting blade, as shown in the figure. Figure 1 , Figure 2 , Figure 4 and Figure 5 The device includes a housing 1. A transverse movable box 2 is fixedly connected to both sides inside the housing 1. A first electric push rod 201 is fixedly connected to the inner side of the transverse movable box 2. A sliding hole 202 is opened on both sides inside the transverse movable box 2. A connecting movable box 3 is slidably connected inside the sliding hole 202.

[0034] One end of the first electric push rod 201 is fixedly connected to the side of the connecting movable box 3. A stepper motor 301 is fixedly connected to the side of the connecting movable box 3. The output end of the stepper motor 301 rotates through the side of the connecting movable box 3 and is fixedly connected to a threaded rod 302. The shaft end of the threaded rod 302 is rotatably connected to the inner side of the connecting movable box 3. A threaded cylinder 303 is threadedly connected to the surface of the threaded rod 302. A movable block 304 is fixedly connected to the surface of the threaded cylinder 303. Through holes 308 are opened on opposite sides inside the connecting movable box 3. L-shaped connecting rods 309 are fixedly connected to opposite sides of the movable block 304. The L-shaped connecting rods 309 are slidably connected in the through holes 308. The bottom ends of the two L-shaped connecting rods 309 are fixedly connected to a base plate 305. Multiple second electric push rods 306 are fixedly connected to the top of the base plate 305. A mounting plate 307 is fixedly connected to the top of the second electric push rods 306. A cutting blade body 4 is mounted on the top of the mounting plate 307. By setting the first electric push rod 201... 01. The connecting movable box 3 can be moved laterally along the sliding hole 202, thereby adjusting the lateral position of the cutting blade body 4. By setting a stepper motor 301, the operation of the stepper motor 301 can drive the threaded rod 302 to rotate, which can make the threaded cylinder 303 and the movable block 304 move on the surface of the threaded rod 302. Through the cooperation of the L-shaped connecting rod 309 and the through hole 308, the longitudinal position of the base plate 305 and the cutting blade body 4 can be adjusted. By setting a second electric push rod 306, the mounting plate 307 and the cutting blade body 4 can be pushed to rise and fall vertically. Through the coordinated action of the three, the cutting blade body 4 can move flexibly in three-dimensional space, which can meet the needs of different cutting positions. At the same time, the sliding cooperation between the sliding hole 202 and the connecting movable box 3, and the sliding connection between the through hole 308 and the L-shaped connecting rod 309, can provide stable guidance for lateral and longitudinal movement, respectively, ensuring that the blade body runs smoothly during the cutting process.

[0035] Please see Figure 4There are four second electric push rods 306, which are respectively set at the four corners of the top of the base plate 305. By distributing the four second electric push rods 306 at the four corners of the top of the base plate 305, a uniform and stable support force can be provided from the four corners when pushing the mounting plate 307 and the cutting blade body 4 to rise and fall. This can avoid the mounting plate 307 tilting and the cutting blade body 4 shaking due to single-point support or uneven force.

[0036] Please see Figure 3 , Figure 4 , Figure 6 and Figure 7 Multiple sliding holes 202 are located within a first annular frame 5, and through holes 308 are located within a second annular frame 6. The connecting movable box 3 slides inside the multiple first annular frames 5, and the L-shaped connecting rod 309 slides in the second annular frame 6. By setting the first annular frames 5 and the second annular frames 6, a further enclosing limit can be formed on the lateral sliding of the connecting movable box 3 in the sliding holes 202 and the longitudinal sliding of the L-shaped connecting rod 309 in the through holes 308. A first annular shrinkage groove 504 is opened on the inner side of the first annular frame 5, and a second annular shrinkage groove 604 is opened on the inner side of the second annular frame 6. By setting the first annular shrinkage groove 504 and the second annular shrinkage groove 604, storage space can be provided for subsequent dust-proofing equipment.

[0037] Please see Figure 6 The first annular shrinkage groove 504 has two first folding plates 502 fixedly connected to opposite sides inside. One side of each first folding plate 502 is fixedly connected to opposite sides of the connecting movable box 3. By setting the first folding plates 502, the connecting movable box 3 can expand or fold as it slides laterally along the first annular frame 5. This allows for dynamic shielding of the gap between the first annular frame 5 and the connecting movable box 3, preventing external dust, debris, and other impurities from entering the equipment through the sliding hole 202. Two... A first slide bar 501 and a first folding plate 502 are fixedly connected to the back of a plurality of first sliders 503. The plurality of first sliders 503 are arranged in two rows and are slidably connected to the back of the first slide bar 501. By setting the first slide bar 501 and the first sliders 503, stable guiding support can be provided for the unfolding and folding of the first folding plate 502. When the connecting movable box 3 drives the first folding plate 502 to move, the plurality of first sliders 503 will slide smoothly along the first slide bar 501, so that the first folding plate 502 maintains a neat shape during unfolding, which can avoid deviation and improve the blocking effect of gaps.

[0038] Please see Figure 7The second annular shrinkage groove 604 has two fixedly connected second folding plates 602 on opposite sides. One side of each second folding plate 602 is fixedly connected to one opposite side of the L-shaped connecting rod 309. By setting the second folding plates 602, the L-shaped connecting rod 309 can be simultaneously unfolded or folded as it slides longitudinally along the second annular frame 6. This provides double dynamic shielding of the gap between the second annular frame 6 and the L-shaped connecting rod 309 from opposite sides, enhancing the dustproof sealing of the equipment and preventing impurities from entering the equipment through the gap created by longitudinal sliding. Two second slide rods 601 are fixedly connected to the inner side of the second annular shrinkage groove 604. Multiple second sliders 603 are fixedly connected to the back of the second folding plate 602. The multiple second sliders 603 are divided into two rows and are slidably connected to the back of the second slide rods 601. By setting the second slide rods 601 and the second sliders 603, a stable guide can be provided for the unfolding and folding of the second folding plate 602. When the L-shaped connecting rod 309 drives the second folding plate 602 to move, the multiple second sliders 603 slide smoothly along the second slide rods 601, which can ensure that the second folding plate 602 is neat when unfolded and avoids displacement.

[0039] The implementation principle of this application embodiment is as follows: When in use, people first control the extension and retraction of the first electric push rod 201 according to the size of the material to be cut and the cutting position requirements, so that it pushes the connecting moving box 3 to slide laterally along the sliding hole 202 in the transverse moving box 2, thereby driving the cutting blade body 4 to adjust to the appropriate transverse cutting position.

[0040] Next, the stepper motor 301 is started, and the stepper motor 301 drives the threaded rod 302 to rotate. Under the action of the threaded connection, the threaded cylinder 303 drives the movable block 304 to move. The movable block 304 drives the base plate 305 and the cutting blade body 4 to move longitudinally along the through hole 308 through the L-shaped connecting rod 309, thereby completing the longitudinal position adjustment of the cutting blade body 4.

[0041] Once the horizontal and vertical positions are determined, the second electric push rod 306 is extended to push the mounting plate 307 and the cutting blade body 4 to rise vertically, so that the cutting blade body 4 contacts the material to be cut and performs the cutting operation.

[0042] During the entire movement process, the first annular frame 5 and the second annular frame 6 can respectively limit the lateral sliding of the connecting moving box 3 and the longitudinal sliding of the L-shaped connecting rod 309. At the same time, the first folding plate 502 and the second folding plate 602 unfold or fold as the moving parts move, which can block the sliding gaps and prevent dust and impurities from entering the equipment. This can ensure the smooth operation of each component and improve the cutting accuracy and service life of the equipment.
