Specific embodiments

[0021] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0022] According to Figure 1-7 As shown, this embodiment proposes a diamond cutter head structure with quick disassembly and assembly, including a main frame body 1, a positioning sleeve 2, a diamond cutter head 3, and a fixing sleeve 4. A positioning sleeve 2 is provided inside the main frame body 1. A diamond cutter head 3 is sleeved outside the positioning sleeve 2. A fixing sleeve 4 is provided on one side of the positioning sleeve 2. A clamping mechanism is provided between the diamond cutter head 3 and the fixing sleeve 4. When this cutter head structure is in use, the diamond cutter head 3 and the fixing sleeve 4 are sequentially sleeved outside the positioning sleeve 2. The clamping mechanism clamps the top of the diamond cutter head 3 through the fixing sleeve 4 to fix the diamond cutter head 3 outside the positioning sleeve 2. When disassembling, only need to loosen the fixing sleeve 4 through the clamping mechanism and sequentially remove the fixing sleeve 4 and the diamond cutter head 3 from outside the positioning sleeve 2.

[0023] The clamping mechanism includes a movable rod 5, a threaded sleeve 6, and a limiting rod 9. A threaded sleeve 6 is rotatably connected to one side of the main frame body 1. A movable rod 5 penetrates through the inside of the main frame body 1. A threaded surface 10 is provided on the outside of the movable rod 5. Two groups of limiting rods 9 are fixedly connected to one end of the movable rod 5. The outer wall of the movable rod 5 is threadedly connected through the inner wall of the threaded surface 10.

[0024] A first through groove 11 is provided inside the positioning sleeve 2. A second through groove 13 is provided inside the fixing sleeve 4. One end of the movable rod 5 penetrates through the inside of the positioning sleeve 2 and the fixing sleeve 4 through the first through groove 11 and the second through groove 13.

[0025] A set of limit rods 9 on the movable rod 5 is restricted in the first through groove 11 inside the positioning sleeve 2, and the threaded sleeve 6 is threadedly connected to the movable rod 5 through the threaded surface 10. When the threaded sleeve 6 rotates forward and backward, it can drive the movable rod 5 to move linearly back and forth, so as to drive another set of limit rods 9 on the movable rod 5 to approach the fixed sleeve 4, that is, apply pressure to the fixed sleeve 4 through the limit rods 9, and the diamond cutter head 3 can be clamped outside the positioning sleeve 2, and then the diamond cutter head 3 is fixed on the main frame body 1, or drive another set of limit rods 9 on the movable rod 5 to move away from the fixed sleeve 4, and the fixed sleeve 4 and the diamond cutter head 3 are successively removed from the outside of the positioning sleeve 2.

[0026] One end of the fixed sleeve 4 is provided with a limit groove 12, the position of the limit groove 12 is perpendicular to that of the second through groove 13, and the outer wall of the limit rod 9 is snap-fitted with the inner wall of the limit groove 12. Before the limit rod 9 clamps the fixed sleeve 4, the position of the fixed sleeve 4 can be adjusted by rotation, so that the limit groove 12 on the fixed sleeve 4 is parallel to the position of the limit rod 9, and the limit rod 9 is snap-fitted into the inside of the limit groove 12, so that the clamping between the limit rod 9 and the fixed sleeve 4 is more firm. When the fixed sleeve 4 is disassembled, the limit rod 9 disengages from the inside of the limit groove 12, and the position of the fixed sleeve 4 is rotated, so that the position of the limit rod 9 is parallel to that of the second through groove 13, avoiding interference of the limit rod 9 with the disassembly of the fixed sleeve 4.

[0027] Threaded holes 8 are symmetrically arranged on the back side of the positioning sleeve 2, connecting bolts 7 penetrate through the two sides of the main frame body 1 symmetrically, and one end of the connecting bolt 7 is threadedly connected to the inner wall of the threaded hole 8. One end of the positioning sleeve 2 is abutted against the inside of the main frame body 1. After the threaded hole 8 on the back side of the positioning sleeve 2 is aligned with the round hole of the main frame body 1, the connecting bolt 7 is screwed into the inside of the threaded hole 8 to fix the positioning sleeve 2 on the inner side of the main frame body 1.

[0028] A top column 14 is fixedly connected to the top of the main frame body 1, a connecting disk 15 is fixedly connected to the top of the top column 14, and a plurality of connecting holes 16 are equidistantly distributed on the outer side of the connecting disk 15. The output end of an external driving device can be provided with a connecting disk 15. The connecting holes 16 on the two connecting disks 15 are aligned, and a double-headed bolt is inserted into the connecting holes 16, and nuts are tightened at both ends of the double-headed bolt to clamp the two connecting disks 15 together, so that the diamond cutter head structure is fixed to the output end of the external driving device.

[0029] A retaining ring is fixedly connected to one side of the top of the diamond cutter head 3, one end of the positioning sleeve 2 penetrates through the inside of the retaining ring, the outer diameter length of the retaining ring is greater than the outer diameter of the fixed sleeve 4, and the fixed sleeve 4 can block the path of the diamond cutter head 3 moving outwards, preventing the diamond cutter head 3 from falling to the outside.

[0030] For the diamond bit structure, a set of limiting rods 9 on the movable rod 5 are restricted in the first through groove 11 inside the positioning sleeve 2, and the threaded sleeve 6 is threadedly connected to the movable rod 5 through the thread surface 10. When the threaded sleeve 6 rotates forward and backward, it can drive the movable rod 5 to move linearly back and forth, so as to drive another set of limiting rods 9 on the movable rod 5 to approach the fixed sleeve 4, that is, apply pressure to the fixed sleeve 4 through the limiting rods 9, and the diamond bit 3 can be clamped outside the positioning sleeve 2, and then the diamond bit 3 is fixed on the main frame body 1, or drive another set of limiting rods 9 on the movable rod 5 to move away from the fixed sleeve 4, and the fixed sleeve 4 and the diamond bit 3 are sequentially removed from the outside of the positioning sleeve 2, making the disassembly and assembly of the diamond bit 3 convenient.
