[0002] In the machining industry, traditional complex hole machining processes are extremely cumbersome. For example, when manufacturing holes in precision instruments or automotive parts, drilling, boring, and chamfering must be performed sequentially. Each step requires changing tools, re-clamping, and meticulous tool setting, consuming a significant amount of machining and auxiliary operation time. Frequent tool changes and long waiting times increase machine tool downtime, causing a sharp decline in overall machining efficiency. These drawbacks are even more pronounced when mass-producing such complex hole parts, resulting in very low output per unit time and significantly reduced production efficiency. Therefore, this utility model proposes a multi-insert design for integrated hole machining. Utility Model Content

[0003] The purpose of this invention is to address the problem that traditional complex hole machining processes are extremely cumbersome, resulting in very low output per unit time and significantly reduced production efficiency. The invention proposes a multi-blade integrated hole machining tool.

[0004] The technical solution of this utility model is as follows: A multi-blade integrated hole machining tool includes a tool body, one end of which is welded with two sets of first diamond cutting blades, which are symmetrically arranged on the outer side of the tool body. Each first diamond cutting blade has a finishing section. A second, third, and fourth diamond cutting blade are welded to the outer side of the tool body, and two sets of each are symmetrically arranged on the outer side of the tool body. A connecting rod is located at the end of the tool body away from the first diamond cutting blades. The connecting rod is a regular square prism, and a connecting component is sleeved on the connecting rod. A locking mechanism is installed in the connecting component to lock the connecting component onto the outer ring of the connecting rod to prevent it from falling off.

[0005] Optionally, the first diamond cutting blade is used for rough reaming, and the first diamond cutting blade has a bottom cutting edge for scraping the surface. The finishing section is used for fine reaming, and the finishing section has a 45° reverse chamfer with a right angle side length of 0.5mm. The second diamond cutting blade has a 45° forward chamfer with a right angle side length of 1mm. The third diamond cutting blade has a 45° reverse chamfer with a right angle side length of 0.45mm. The fourth diamond cutting blade has a 45° forward chamfer with a right angle side length of 1.05mm.

[0006] Optionally, the connecting assembly includes a mounting sleeve slidably connected to the outer ring of the connecting rod, a transition plate being fixedly connected to the end of the mounting sleeve away from the tool body, and a mounting rod being installed on the side of the transition plate away from the mounting sleeve.

[0007] Optionally, the locking mechanism includes slots on both sides of the connecting rod, a locking plate slidably mounted on the slot, the locking plate slidably connected to the mounting sleeve, the locking plate being arranged in a "U" shape, a moving block slidably connected to the locking plate, the moving block slidably connected to the slot, and the moving block also slidably engaging with the mounting sleeve.

[0012] This utility model, through the setting of a first diamond cutting blade, a second diamond cutting blade, a third diamond cutting blade, and a fourth diamond cutting blade, with each blade assigned to different processing content, enables complex hole processing to be completed in one go, which can reduce the tool change time in the production workshop and improve production efficiency.

[0013] Furthermore, by setting a locking mechanism, the connecting component is locked onto the connecting rod. Thus, when the tool body is connected to the power source through the chuck, different mounting rods on different connecting components can be replaced to adapt to different chucks, making the tool body securely installed and preventing vibration during machining from affecting accuracy.

[0028] Example

[0029] like Figures 1 to 4 As shown, this utility model proposes a multi-blade integrated hole machining tool, comprising a tool body 6. Two sets of first diamond cutting blades 1 are welded to one end of the tool body 6, symmetrically arranged on the outer side of the tool body 6. Each first diamond cutting blade 1 has a finishing section 2. Two sets of second, third, and fourth diamond cutting blades 3 and 4 are welded to the outer side of the tool body 6 and symmetrically arranged. The tool body 6 is made of cemented carbide for high rigidity, and features a PCD material welding and a central internal cooling design, resulting in high machining efficiency and excellent surface roughness, significantly extending the tool body 6's lifespan. The first diamond cutting blade 1 is used for rough reaming and has a bottom cutting edge for scraping. The finishing section 2 is used for fine reaming and has a 45° reverse chamfer with a right-angle side length of 0.5mm. The second diamond cutting blade 3 has a 45° forward chamfer with a right-angle side length of 1mm. The third diamond cutting blade 4 has a 45° reverse chamfer with a right-angle side length of 0.45mm. The fourth diamond cutting blade 5 has a 45° forward chamfer with a right-angle side length of 1.05mm. Each blade is assigned a different machining function, allowing complex hole machining to be completed in one pass, reducing tool change time in the production workshop and improving production efficiency.

[0030] Furthermore, the aforementioned cutting tool also includes a connecting rod 61 disposed at the end of the cutting tool body 6 away from the first diamond cutting blade 1. The connecting rod 61 is configured as a regular square prism, and when the connecting rod 61 rotates, it drives the cutting tool body 6 to move synchronously. A connecting assembly 8 is sleeved on the connecting rod 61. The connecting assembly 8 includes a mounting sleeve 81 slidably connected to the outer ring of the connecting rod 61. When the mounting sleeve 81 rotates, it drives the connecting rod 61 to rotate synchronously, thereby driving the cutting tool body 6 to rotate. A transition plate 82 is fixedly connected to the end of the mounting sleeve 81 away from the cutting tool body 6. A mounting rod 83 is installed on the side of the transition plate 82 away from the mounting sleeve 81. The mounting rod 83 on different connecting assemblies 8 adopts different shapes, such as cylindrical, triangular prism, or square prism, to adapt to different chucks.

[0031] Furthermore, the aforementioned cutting tool also includes a locking mechanism 7 installed in the connecting assembly 8. The locking mechanism 7 is used to lock the connecting assembly 8 onto the outer ring of the connecting rod 61 to prevent it from falling off. The locking mechanism 7 includes slots 71 on both sides of the connecting rod 61. A locking plate 72 is slidably installed on the slots 71 and is slidably connected to the mounting sleeve 81. The locking plate 72 is U-shaped and is locked in the slots 71 to limit the mounting sleeve 81 and prevent it from slipping off. A moving block 73 is slidably connected to the locking plate 72 and is slidably connected to the slots 71. The moving block 73 also slides with the mounting sleeve 81, and the moving block 73, together with the locking plate 72, limits the mounting sleeve 81. Limiting blocks 74 are fixedly connected to both ends of the moving block 73. The slots 71 have grooves 75 corresponding to the limiting blocks 74. The limiting blocks 74 are slidably connected to the grooves 75, making the movement of the moving block 73 smooth. A fixing block 76 is fixedly connected to the slot 71. The fixing block 76 slides in conjunction with the mounting sleeve 81, facilitating the sliding of the fixing block 76 within the mounting sleeve 81 and limiting the sliding range of the clamping plate 72 within the mounting sleeve 81. A pull rod 77 is slidably connected to the fixing block 76. One end of the pull rod 77 is fixedly connected to the moving block 73, facilitating the movement of the moving block 73. Multiple threaded rods 78 are threadedly connected to the fixing block 76. A positioning ring 79 is fitted onto one end of each threaded rod 78. When the positioning ring 79 is tightened, it moves the moving block 73 closer to the connecting rod 61, and simultaneously, through a reaction force, clamps the clamping plate 72 into position in the slot 71. The positioning ring 79 is fixedly connected to the side of the moving block 73 away from the connecting rod 61 for positioning.

[0032] In this embodiment, during installation, by selecting the connecting component 8 corresponding to the chuck, pulling the pull rod 77 causes the moving block 73 to move smoothly under the limiting action of the limiting block 74 and the sliding groove 75, so that the moving block 73 moves to the position closest to the fixed block 76. The moving clamping plate 72 is integrated with the fixed block 76, so that the gap between the clamping plate 72 and the moving block 73 can pass through the connecting rod 61. The mounting sleeve 81 is put on the connecting rod 61, and the clamping plate 72 is moved so that the clamping plate 72 is locked in the position of the slot 71. Two sets of threaded rods 78 are installed and tightened. The threaded rods 78 drive the moving block 73 into the slot 71 for limiting. At the same time, the reaction force of the threaded rods 78 after tightening causes the clamping plate 72 to also press the position of the slot 71, so that the clamping plate 72 and the moving block 73 are locked in the position of the slot 71. At the same time, since the clamping plate 72 and the moving block 73 are slidably connected in the mounting sleeve 81, the mounting sleeve 81 is prevented from moving away from the tool body 6, so that the tool body 6 is firmly fixed.

[0033] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
