Description

Technical Field

[0001] The utility model relates to the technical field of numerical control tools, in particular to a combined high-stability numerical control tool. Background Art

[0002] In the field of mechanical processing, the precision and stability of CNC tools have a vital impact on the processing quality and efficiency. In the design of traditional CNC tools, the connection between the tool handle and the tool head is often fixed by screws or welding. Although it can provide a certain degree of stability, it is inconvenient to disassemble and assemble, and has low efficiency. The screw fixing method requires the use of tools for tightening and disassembly, and it is also necessary to disassemble and assemble multiple screws. The operation is cumbersome and time-consuming; while the welding method cannot achieve the rapid replacement of the tool head, which is not conducive to flexible adjustment in production. Therefore, we proposed a combined high-stability CNC tool that is easy to disassemble and assemble.

[0003] The prior art discloses a combined high-stability CNC tool with an application number of CN202122357552.6, comprising a tool seat, a tool body being provided on the left side of the tool seat, and a first mounting component and a second mounting component. The first mounting component is used to mount and fix the end of the tool body. The first mounting component is located on the side of the tool seat close to the tool body. The second mounting component is used to fix the middle part of the tool body. The second mounting component is sleeved on the surface of the tool body, and the second mounting component is fixedly connected to the tool seat through multiple sets of reinforcing rods.

[0004] The prior art uses multiple bolts to fix the tool. First, multiple bolt fixation is cumbersome for the staff. Second, if a bolt is lost, it is necessary to match the corresponding bolt, which makes it difficult to improve work efficiency.

[0005] Therefore, it is necessary to design a combined high-stability CNC tool that is highly practical and easy to disassemble and assemble. Utility Model Content

[0006] The purpose of the utility model is to provide a combined high-stability CNC tool to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a combined high-stability CNC tool, including a tool handle, a long rod is connected to the inside of the tool handle, a disassembly mechanism is connected to one side of the long rod, a tool head corresponds to one side of the disassembly mechanism, and a limiting mechanism is connected to the other side of the long rod.

[0008] According to the above technical solution, the disassembly and assembly mechanism includes a conical block, which is fixedly connected to the long rod, and a plurality of elastic blocks are fixedly connected to one side of the knife handle, the top of the elastic block fits the conical block, and the elastic block corresponds to the knife head.

[0009] According to the above technical solution, the long rod is a threaded rod, and the long rod and the inside of the handle are threadedly connected.

[0010] According to the above technical solution, a protrusion is fixedly connected to the outer side of the elastic block, the top of the cutter head is hollow, and a plurality of grooves are provided on the inner side of the top of the cutter head, and the protrusions and the grooves correspond to each other.

[0011] According to the above technical solution, one end of the large circle of the conical block corresponds to the cutter head, and one end of the small circle of the conical block is fixedly connected to the long rod.

[0012] According to the above technical solution, gaps are left between the plurality of elastic blocks.

[0013] According to the above technical solution, the limiting mechanism includes a round block, which is fixedly connected to a long rod, and two plug rods are slidably connected inside the round block. A plurality of circular grooves are provided on one side of the knife handle, and the plug rods and the circular grooves correspond to each other.

[0014] According to the above technical solution, the cutter head is spiral-shaped.

[0015] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0016] (1) By providing a disassembly and assembly mechanism, the staff can rotate the round block to drive the long rod to rotate, and the threaded connection allows the long rod to move, so that the conical block can be moved to the inside of the elastic block, and the elastic block can be pushed outward to complete the fixation, and vice versa, the disassembly can be completed. The disassembly and assembly can be completed by rotation, which is convenient for the staff to operate and greatly improves the work efficiency. At the same time, the worn cutter head can be directly replaced individually, saving costs;

[0017] (2) By setting a limit mechanism, after the cutter head is fixed, a second fixation can be performed by inserting a rod into the inside of the circular groove.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 The utility model provides a technical solution: a combined high-stability CNC tool, including a handle 1, a long rod 2 is connected inside the handle 1, a disassembly mechanism is connected to one side of the long rod 2, a cutter head 3 is corresponding to one side of the disassembly mechanism, and a limit mechanism is connected to the other side of the long rod 2; when the staff is ready to start working, the cutter head 3 needs to be installed first, the staff puts the cutter head 3 on the disassembly mechanism, and then rotates the long rod 2 to expand the disassembly mechanism outward, so as to support and fix the cutter head 3, and then fix it again through the limit mechanism after the fixation is completed, so as to ensure the stability of the cutter head 3 during the working process. By providing the disassembly mechanism, the disassembly process of the cutter head 3 and the handle 1 is simple and fast, which improves the work efficiency, and the worn cutter head 3 can be directly replaced, which greatly saves the cost. By providing the limit mechanism, the secondary fixation of the cutter head 3 is realized, and the stability of the cutter head 3 during the working process is ensured. This double fixing mechanism effectively reduces the vibration and looseness that may occur in the tool during high-speed cutting, thereby improving the processing accuracy and the service life of the tool.

[0024] The disassembly and assembly mechanism includes a conical block 23, which is fixedly connected to the long rod 2. A plurality of elastic blocks 11 are fixedly connected to one side of the knife handle 1. The top of the elastic block 11 fits the conical block 23, and the elastic block 11 corresponds to the cutter head 3. When the cutter head 3 is not installed at the beginning, the conical block 23 protrudes from the outside of the elastic block 11. The elastic block 11 is made of elastic material and metal material, has a certain supporting force and is also elastic and bendable. The staff puts the cutter head 3 on the outside of the conical block 23 and the elastic block 11. At this time, the fixed knife handle 1 rotates the long rod 2 inside. The long rod 2 moves while rotating, and the conical block 23 moves toward one end of the elastic block 11. The conical block 23 stretches the elastic block 11. When stretching, the conical block 23 presses the elastic block 11 and then presses the inner side of the cutter head 3 to fix it. When the cutter head 3 needs to be disassembled and replaced, the long rod 2 is rotated in the opposite direction. By providing a disassembly and assembly mechanism, the cutter head 3 can be fixed and disassembled by rotating the long rod 2, which is convenient for the staff to operate and improves the work efficiency.

[0025] The long rod 2 is a threaded rod, and the long rod 2 and the inside of the handle 1 are threadedly connected; because they are threadedly connected, when the long rod 2 is rotated, the long rod 2 will move while rotating, and the cutter head 3 can be disassembled and assembled by adjusting the direction of rotation, which is convenient for the staff to operate.

[0026] A protrusion 12 is fixedly connected to the outer side of the elastic block 11, the top of the cutter head 3 is hollow, and a plurality of grooves are provided on the inner side of the top of the cutter head 3, and the protrusion 12 corresponds to the groove; when the staff puts the cutter head 3 on the outer side of the elastic block 11, the protrusion 12 just faces the circular groove 13 on the inner side of the cutter head 3, and the staff then rotates the long rod 2, and the conical block 23 at one end of the long rod 2 opens the elastic block 11, and the protrusion 12 is pushed into the inside of the circular groove 13, so that the fixation between the cutter head 3 and the elastic block 11 is more stable, and it will not move even under high-speed rotation.

[0027] One end of the large circle of the conical block 23 corresponds to the cutter head 3, and one end of the small circle of the conical block 23 is fixedly connected to the long rod 2; one end of the conical block 23 is large and the other end is small, so that when the conical block 23 moves toward the interior of the multiple elastic blocks 11, the large end of the conical block 23 is inserted into the interior of the elastic block 11, thereby stretching the elastic block 11, thereby pressing against the inner side of the cutter head 3 to fix it, and vice versa, the cutter head 3 can be removed.

[0028] There are gaps between the multiple elastic blocks 11, which can give the elastic blocks 11 a certain amount of room for expansion and retraction.

[0029] The limiting mechanism includes a round block 21, which is fixedly connected to the long rod 2. Two plug rods 22 are slidably connected inside the round block 21. A plurality of circular grooves 13 are provided on one side of the handle 1, and the plug rods 22 correspond to the circular grooves 13. When the staff needs to rotate the long rod 2 to complete the fixation, the two plug rods 22 are lifted from the circular grooves 13, and then the round block 21 is rotated, so that the long rod 2 can be rotated. This makes the operation of rotating the round block 21 more convenient. After the fixation of the cutter head 3 is completed, the plug rod 22 is inserted into the circular groove 13. There are multiple circular grooves 13, so that no matter the range of rotation, the plug rod 22 can always be inserted into the two circular grooves 13. By setting a limiting mechanism, after the cutter head 3 is fixed, it can be fixed for a second time to further prevent loosening during the cutting process.

[0030] The cutter head 3 is spiral-shaped; this shape can make the cutter produce a rotating effect during the cutting process, thereby increasing the continuity and stability of the cutting.
