Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a PCD forming tool for hole machining. Background Technology

[0002] Drilling is a machining method that uses a rotating drill bit to cut cylindrical holes in solid materials. It is commonly used in the manufacture of mechanical parts, building structures, and electronic products. During drilling, the drill bit rotates at high speed and applies pressure, gradually cutting the material to form a hole. The diameter and depth of the hole can be adjusted as needed to meet different application requirements. The quality and accuracy of the drilling depend on factors such as the type of drill bit, its rotational speed, feed rate, and the properties of the material. Existing PCD forming tools for drilling and milling external cylindrical composite grooves require selecting different models of PCD forming tools based on the size of the hole, leading to cumbersome assembly and disassembly steps and reduced drilling efficiency. Therefore, this invention proposes a PCD forming tool for hole machining. Utility Model Content

[0029] like Figures 2 to 4 As shown, the adjusting assembly 8 includes a fixing block 81 fixedly disposed inside the through hole 4. A threaded rod 82 is rotatably disposed at one end of the fixing block 81. An adjusting cap 83 is fixedly connected to one end of the threaded rod 82, and the adjusting cap 83 is movably sleeved with the through hole 4 to ensure stable rotation of the adjusting cap 83 and the threaded rod 82. A threaded sleeve 84 is threadedly sleeved on the outer wall of the threaded rod 82. A plurality of first linkage seats 85 are fixedly disposed on the outer wall of the threaded sleeve 84. A linkage rod 86 is rotatably connected to the first linkage seat 85, and the linkage rod 86 is located inside the groove 5 to facilitate simultaneous movement of the linkage rod 86. A second linkage seat 87 is rotatably connected to one end of the linkage rod 86. A guide block 88 is fixedly connected to one end of the second linkage seat 87. The guide block 88 is slidably connected to the guide groove 6 and fixedly connected to the blade 7 to facilitate movement of the blade 7, thereby adjusting the position of the blade 7 and facilitating the processing of drill holes of different sizes.

[0030] like Figure 3 and Figure 5 As shown, a locking block 9 is fixedly installed at one end of the blade 7, and the locking block 9 is integrally formed with the blade 7. A diamond cutting block 10 is sleeved on the locking block 9, and the diamond cutting block 10 is set at 0 degrees, 89 degrees, 180 degrees and 271 degrees, so that each diamond cutting block 10 can share different cutting forces, so that complex outer circular grooves can be machined in one go. The locking block 9 and the diamond cutting block 10 are fixedly connected by a limiting bolt 11, which can stably limit the diamond cutting block 10 and facilitate disassembly and replacement.

[0031] Furthermore, an annular groove 12 is provided on the inner wall of the through hole 4, and a sliding ring 13 is slidably arranged inside the annular groove 12.
