Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

Referring to Fig. 1-2, a tool holder for a boring machine includes a tool holder 1, on which a tool bar 2 is installed, and a through groove 12 is arranged transversely on the tool holder 1, and two knives are slidably connected in the through groove 12. The head 3 and the through groove 12 are rectangular grooves, and the cutter head 3 is in a rectangular shape, so that the cutter head 3 cannot rotate in the through groove 12 .

Blades 4 are installed on the two cutter heads 3, and the blades 4 are installed on the cutter heads 3 through hexagonal bolts, and the blades 4 are installed on the upper end of the cutter heads 3; The mechanism is connected with the cutter head 3, the connecting mechanism includes an L-shaped groove 13 arranged at the end of the cutter head 3, and the threaded cylinder 7 is fixedly connected with an L-shaped block 14, and the L-shaped block 14 is installed in the L-shaped groove 13, wherein, The minimum distance between the upper and lower inner walls of the L-shaped groove 13 is greater than the maximum height of the L-shaped block 14, so that the L-shaped block 14 can be taken out from the L-shaped groove 13.

Screw rod 8 is connected with threaded cylinder 7 internal threads, and round rod 10 is coaxially fixed on the screw rod 8, and support block 9 supporting round rod 10 is installed in the through groove 12, and round rod 10 runs through support block 9 and is connected with it in rotation; The frame 1 is provided with a driving rod 6 connected to it in rotation up and down, and the driving rod 6 is connected to the round rod 10 in transmission. The lower end of the driving rod 6 and the round rod 10 are equipped with a bevel gear 11, and the two bevel gears 11 are meshed to drive A twist block 5 is installed on the upper end of the rod 6, and the twist block 5 is connected with the driving rod 6 by welding, and the outer wall of the twist block 5 is provided with anti-slip lines.

When the utility model is in use, the staff manually rotates the twist block 5, the rotation of the twist block 5 drives the driving rod 6 to rotate, and the rotation of the driving rod 6 drives the bevel gear 11 and the round rod 10 to rotate, thereby realizing the rotation of the screw rod 8. It cannot slide in the through groove 12, and the L-shaped block 14 cannot rotate in the L-shaped groove 13, so the threaded cylinder 7 cannot rotate. When the screw rod 8 rotates, the threaded cylinder 7, the L-shaped block 14, the cutter head 3 and the blade can be driven 4, through the cooperation of the screw rod 8 and the threaded cylinder 7, the blade 4 can be fine-tuned and the adjustment accuracy is high;

If it is necessary to maintain the cutter head 3 or the blade 4, the staff rotates the twist block 5 equally so that the cutter head 3 stretches out of the through groove 12 completely. The top is offset against the upper end of the L-shaped block 14, and the staff can directly take out the cutter head 3 horizontally, which is convenient and quick; during installation, the staff puts the L-shaped groove 13 on the L-shaped block 14 and then moves the cutter head 3 upwards, so that The L-shaped block 14 is located in the L-shaped groove 13 and offsets it. At this time, the cutter head 3 is facing the through groove 12. The staff reverses the twist block 5 to drive the threaded cylinder 7 to reset, and the cutter head 3 can be pulled into the through groove 12. , to realize the installation of the cutter head 3.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. The equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
