Description

Technical Field

[0001] This utility model relates to the field of CNC cutting tools, and in particular to a deformable assembly type CNC cutting tool. Background Technology

[0002] CNC cutting tools are tool components that are driven by CNC programs to perform cutting tasks on machine tools, and their installation and positioning accuracy directly determines the machining quality.

[0003] Existing technologies, such as the utility model patent with publication number CN212043803U, disclose a cutting tool for CNC machine tools. This patent employs a tool holder and a cutting tool connected to the tool holder. The cutting tool has at least one water outlet. The CNC machine tool cutting tool also includes a cooling channel disposed within the tool holder and at least one connecting channel communicating with the cooling channel. The cutting tool has a first positioning hole, and the tool holder has a second positioning hole that mates with the first positioning hole via a fastener. When the first positioning hole and the second positioning hole are aligned, the connecting channel communicates with the water outlet. By providing a water outlet on the cutting tool and a cooling channel on the tool holder, along with a connecting channel connecting the water outlet and the cooling channel, coolant is directly channeled to the cutting tool for cooling, which is convenient, fast, and avoids resource waste. Furthermore, the inclusion of a chip groove prevents the cutting tool from scratching the hole wall due to the difficulty in removing chips during deep machining, thus avoiding problems that could affect the cutting tool's lifespan and machining efficiency.

[0004] The inventors discovered the following problems in the use of CNC cutting tools in their daily work: CNC cutting tools use a static installation structure with rigid collets or bolts, and the tool spacing is fixed and cannot be dynamically adjusted. Traditional structures only support single tool centering and cannot achieve the function of double tool offset / single tool centering. Adjusting the tool layout requires tools to remove and install bolts. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as low flexibility in deformation and assembly, which leads to low work efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a deformable assembly-type CNC cutting tool, comprising: a CNC spindle, an adjustment structure at the lower end of the CNC spindle, the adjustment structure including a connecting frame, the connecting frame being fixedly connected to the CNC spindle, an adjustment frame being fixedly connected to the side of the connecting frame away from the CNC spindle, mounting frames being fixedly connected to both sides of the adjustment frame, a locking rod being slidably connected to the inner wall of the mounting frame, a spring being sleeved on the arc surface of the locking rod, the two ends of the spring being fixedly connected to the locking rod and the mounting frame respectively, and mounting rods being slidably connected to the arc surfaces of the two locking rods. The mounting rod is slidably connected to the inner wall of the mounting frame. Several fixing blocks are fixedly connected to the surface of the adjustment frame. Each pair of fixing blocks is a group. A bidirectional screw is rotatably connected to the inner wall of one group of fixing blocks. Two first positioning plates are threadedly connected to the arc surface of the bidirectional screw. The first positioning plates are slidably connected to the inner wall of the adjustment frame. A second positioning plate is fixedly connected to the inner wall of the adjustment frame. A CNC tool body is slidably connected to the inner wall of each of the two first positioning plates. A mounting hole is opened at the upper end of the CNC tool body. The inner wall of the mounting hole is slidably connected to the mounting rod.

[0007] The aforementioned components achieve the following effects: by adjusting the structure, the CNC tool body can be quickly installed, disassembled, and adjusted in multiple positions, making it easy to deform and assemble tools according to different processing requirements, thereby improving processing flexibility and efficiency.

[0008] Preferably, a pull ring is rotatably connected to the end of the clamp rod away from the mounting rod, and the pull ring is specifically a stainless steel ring.

[0009] The aforementioned components achieve the following effects: they facilitate the operator in applying force to pull the lever, simplify the disassembly process, and enhance the ease of operation for deformable assembly.

[0010] Preferably, the end of the clamp rod near the mounting rod is arc-shaped.

[0011] The effect achieved by the above components is to reduce friction, making it easier for the locking lever to slide into or out of the mounting lever, and improving the smoothness of assembly and disassembly.

[0012] Preferably, both ends of the bidirectional screw are fixedly connected with a plurality of anti-slip protrusions, and the plurality of anti-slip protrusions are evenly distributed on the bidirectional screw.

[0013] The effects achieved by the above components are: increasing the friction for manual operation, facilitating precise rotation of the bidirectional screw to adjust the position of the cutter body, and supporting rapid deformation assembly.

[0014] Preferably, a sliding rod is fixedly connected to one side of the other set of fixed blocks that are close to each other, and the arc surface of the sliding rod is slidably connected to the first positioning plate.

[0015] The aforementioned components provide additional support and guidance, ensuring smooth movement of the first positioning plate and enhancing the stability and reliability of the assembled structure.

[0016] Preferably, counterweights are fixedly connected to the sides of the other set of fixed blocks that are far apart from each other.

[0017] The effects achieved by the above components are: balancing the weight of the equipment, reducing vibration during operation, improving processing accuracy, and making them suitable for high-stability deformation assembly requirements.

[0018] Preferably, a scale is provided on the side of the adjustment frame near the bidirectional screw.

[0019] The effect achieved by the above components is to provide visual position reference, which facilitates precise adjustment of the CNC tool body position.

[0020] Compared with related technologies, the deformable assembly CNC cutting tool provided by this utility model has the following beneficial effects:

[0021] By setting up an adjustment structure, the CNC tool body can be quickly deformed, assembled, and precisely positioned. Rotating a bidirectional screw drives two first positioning plates to move synchronously, flexibly adjusting the tool body spacing or centering it on the second positioning plate. A spring-return locking rod, in conjunction with a removable mounting rod, enables tool-free assembly and disassembly of the tool body. The mounting rod penetrates the tool body to form a rigid support. Combined with sliding rod guidance and counterweight vibration reduction, the CNC tool body can be quickly installed, disassembled, and adjusted in multiple positions. This facilitates the deformation and assembly of tools according to different processing requirements, improving processing flexibility and efficiency, and meeting the flexible processing needs of various parts.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1 to 4 The present invention provides a deformable assembly type CNC tool, comprising: a CNC spindle 1, wherein the lower end of the CNC spindle 1 is provided with an adjustment structure 2.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 4The adjustment structure 2 includes a connecting frame 201, which is fixedly connected to the CNC spindle 1. An adjustment frame 202 is fixedly connected to the side of the connecting frame 201 away from the CNC spindle 1. Mounting frames 203 are fixedly connected to both sides of the adjustment frame 202. A locking rod 204 is slidably connected to the inner wall of the mounting frame 203. A spring 205 is fitted onto the arc surface of the locking rod 204, and both ends of the spring 205 are fixedly connected to the locking rod 204 and the mounting frame 203, respectively. Mounting rods 207 are slidably connected to the arc surfaces of the two locking rods 204 and are slidably connected to the inner wall of the mounting frame 203. Several fixing blocks 208 are fixedly connected to the surface of the adjustment frame 202. 208 are arranged in pairs. One pair of fixed blocks 208 has a bidirectional screw 209 rotatably connected to its inner wall. The arc surface of the bidirectional screw 209 is threaded with two first positioning plates 210. The first positioning plates 210 are slidably connected to the inner wall of the adjusting frame 202. A second positioning plate 211 is fixedly connected to the inner wall of the adjusting frame 202. CNC tool bodies 212 are slidably connected to the inner walls of both first positioning plates 210. The upper end of the CNC tool body 212 has a mounting hole 213, and the inner wall of the mounting hole 213 is slidably connected to the mounting rod 207. The adjusting structure 2 enables quick installation, disassembly, and multi-position adjustment of the CNC tool body 212, facilitating deformation and assembly according to different processing requirements. The cutting tool improves processing flexibility and efficiency. A pull ring 206, specifically a stainless steel ring, is rotatably connected to the end of the locking lever 204 furthest from the mounting rod 207, facilitating the operator's pulling of the locking lever 204, simplifying the disassembly process, and enhancing the ease of operation for deformable assembly. The end of the locking lever 204 near the mounting rod 207 is arc-shaped to reduce friction, making it easier for the locking lever 204 to slide into or out of the mounting rod 207, improving the smoothness of assembly and disassembly. Several anti-slip protrusions are fixedly connected to both ends of the bidirectional screw 209, evenly distributed on the bidirectional screw 209, increasing the friction for manual operation and facilitating precise rotation of the bidirectional screw 209 to adjust the cutting tool. The first positioning plate 210 supports rapid deformation and assembly. Another set of fixed blocks 208 are fixedly connected to a slide rod 214 on the side close to each other. The arc surface of the slide rod 214 is slidably connected to the first positioning plate 210, providing additional support and guidance to ensure that the first positioning plate 210 moves smoothly and enhances the stability and reliability of the assembly structure. The other set of fixed blocks 208 are fixedly connected to counterweights 215 on the side far from each other to balance the weight of the equipment, reduce vibration during operation, and improve processing accuracy. It is suitable for high-stability deformation and assembly requirements. The adjustment frame 202 is provided with a scale 216 on the side close to the bidirectional screw 209 to provide visual position reference and facilitate precise adjustment of the position of the CNC tool body 212.

[0031] The working principle of the deformable assembly CNC cutting tool provided by this utility model is as follows: By setting the adjustment structure 2, the bidirectional screw 209 is rotated first. The bidirectional screw 209 rotates along the inner wall of the fixed block 208. The bidirectional screw 209 drives the two first positioning plates 210 to move by means of the thread. The two first positioning plates 210 move simultaneously along the inner wall of the adjustment frame 202 towards each other. The first positioning plates 210 drive the CNC cutting tool body 212 to move. During this process, the CNC cutting tool body 212 always moves along the surface of the mounting rod 207. When disassembling or assembling the CNC tool body 212, first pull the two locking rods 204 away from the mounting rod 207. The locking rods 204 move along the mounting bracket 203, and the spring 205 is in a compressed state, releasing the restriction on the mounting rod 207. At this time, the mounting rod 207 can be pulled out laterally. The mounting rod 207 moves along the mounting bracket 203 and the mounting hole 213 on the CNC tool body 212, releasing the restriction on the CNC tool body 212. At this time, the CNC tool body 212 can be moved downward, so that the CNC tool body 212 is disengaged from the adjusting frame 202 and the first... First, a positioning plate 210 is installed. Then, according to requirements, the new CNC tool body 212 is moved from bottom to top into the first positioning plate 210 for reset. The mounting rod 207 is moved laterally so that it passes through the mounting hole 213 on the CNC tool body 212 along the mounting frame. The two locking rods 204 are released, and under the action of the spring force 205, the two locking rods 204 slide into the two ends of the mounting rod 207 respectively, fixing the mounting rod 207 on the two mounting brackets 203, thereby fixing the position of the new CNC tool body 212. Similarly, the CNC tool body 212 can be moved from bottom to top into the first positioning plate 210 for reset. The control body 212 is installed in the second positioning plate 211 at the center of the adjustment frame 202. The pull ring 206 makes it easy for the operator to pull the locking rod 204. One end of the locking rod 204 is arc-shaped to reduce friction, making it easier for the locking rod 204 to slide into or out of the mounting rod 207. The slide bar 214 provides additional support and guidance to ensure that the first positioning plate 210 moves smoothly. The counterweight 215 balances the weight of the equipment and reduces vibration during operation. The scale 216 provides a visual position reference to facilitate precise adjustment of the position of the CNC control body 212.
