The method for accurately adjusting the position of the hole results in low drilling accuracy. After the sleeve 36 is clamped and fixed, the knob 7 is turned to drive the first screw rod 6 to rotate, and the first screw rod 6 drives the slider 8 thereon to move horizontally, and the slider 8 drives the pointer 14 and the milling cutter 12 thereon to move horizontally. The pointer 14 and the milling cutter 12 move synchronously, and the drilling position of the milling cutter 12 is accurately adjusted according to the scale 13 scale pointed by the pointer 14. After the two milling cutters 12 are accurately adjusted, the two groups of hydraulic cylinders 2 are operated, and the two groups of hydraulic rods 3 drive the two groups of mounting plates 4 to move vertically downward. The two groups of mounting plates 4 drive the first motor, the rotating frame 11 and the milling cutter 12 thereon to move vertically downward. At the same time, the first motor drives the milling cutter 12 to rotate at high speed, and the two groups of milling cutters 12 quickly drill the sleeve 36.

During the horizontal movement of the first clamping plate 25 to the second clamping plate 26, the first clamping plate 25 first contacts the sleeve 36, and then pushes the sleeve 36 to move horizontally to the second clamping plate 26 until the sleeve 36 and the second clamping plate 26 are in contact, thereby achieving the clamping and fixing of the sleeve 36 by the first clamping plate 25 and the second clamping plate 26. At the same time, the sleeve 36 is stably clamped in the placement groove 19 in the vertical direction. During the drilling process, the first clamping plate 25 and the second clamping plate 26 horizontally position the sleeve 36, and the placement groove 19 vertically positions the sleeve 36. This structure is beneficial to improving the stability of the sleeve 36 by increasing the clamping area of ​​the sleeve 36.

[0022] See also Figure 5As shown, a plate groove 28 is provided on the second clamping plate 26, and a movable plate 29 is installed in the plate groove 28. A limiting groove 30 is provided in the second clamping plate 26, and a limiting rod 31 is installed in the limiting groove 30. One side of the limiting rod 31 is connected to the movable plate 29, and a spring 32 is installed between the limiting rod 31 and the inner wall of the limiting groove 30. A first electrode sheet 33 is installed on the side wall of the limiting rod 31, and a second electrode sheet 34 is installed on the inner wall of the limiting groove 30. The first electrode sheet 33 and the second electrode sheet 34 are connected to the indicator light 27 through an internal circuit. A control panel 35 is installed on the side wall of the base 17, and the control panel 35 is connected to the second motor 23 and the indicator light 27 through an internal circuit. When working, the existing drilling tool cannot control the clamping force in the process of clamping the sleeve 36. Excessive clamping force will cause damage to the sleeve 36, resulting in poor protection of the sleeve 36. The sleeve 36 is pushed to move horizontally toward the second clamping plate 26 by the first clamping plate 25, and the sleeve 36 is first connected to the The movable plate 29 on the second clamping plate 26 contacts and continuously pushes the movable plate 29 into the plate groove 28, and the movable plate 29 drives the limiting rod 31 to move horizontally in the limiting groove 30. At the moment when the sleeve 36 contacts the second clamping plate 26, the movable plate 29 is completely pushed into the plate groove 28. At this time, the second electrode sheet 34 on the limiting rod 31 contacts the first electrode sheet 33, so that the internal circuit of the indicator light 27 is connected, and the indicator light 27 sends an electrical signal to the control panel 35. After receiving the electrical signal, the control panel 35 controls the second motor 23 to stop operating. At this time, the first clamping plate 25 stops moving, that is, the first clamping plate 25 pushes the sleeve 36 to move horizontally toward the second clamping plate 26. At the moment when the sleeve 36 contacts the second clamping plate 26, the first clamping plate 25 stops moving. At this time, the clamping force of the first clamping plate 25 and the second clamping plate 26 on the sleeve 36 is moderate, thereby realizing the adjustment of the clamping force, avoiding excessive clamping force to damage the sleeve 36, and being beneficial to improving the protection of the sleeve 36.

[0023] Working principle: In the process of clamping and fixing the sleeve 36 with the existing drilling tool, the stability of the sleeve 36 is poor due to the small clamping area. By placing the sleeve 36 into the placement groove 19, the control panel 35 controls the second motor 23 to operate, the second motor 23 drives the second screw rod 22 to rotate, the second screw rod 22 drives the moving block 24 to move horizontally, and the moving block 24 drives the first clamping plate 25 to move horizontally. During the process of the first clamping plate 25 moving horizontally toward the second clamping plate 26, the first clamping plate 25 first contacts with the sleeve 36, and then pushes the sleeve 36 toward the second clamping plate 26. The first clamping plate 25 and the second clamping plate 26 are moved horizontally until the sleeve 36 is in contact with the second clamping plate 26, so that the first clamping plate 25 and the second clamping plate 26 clamp the sleeve 36 and fix it. At the same time, the sleeve 36 is stably clamped in the placement groove 19 in the vertical direction. During the drilling process, the first clamping plate 25 and the second clamping plate 26 horizontally position the sleeve 36, and the placement groove 19 vertically positions the sleeve 36. This structure increases the clamping area of ​​the sleeve 36, which is beneficial to improving the stability of the sleeve 36. The existing drilling tool cannot control the clamping force during the clamping process of the sleeve 36. Excessive force may damage the sleeve 36, resulting in poor protection of the sleeve 36. The sleeve 36 is pushed to move horizontally toward the second clamping plate 26 by the first clamping plate 25. The sleeve 36 first contacts the movable plate 29 on the second clamping plate 26, and continuously pushes the movable plate 29 into the plate groove 28. The movable plate 29 drives the limit rod 31 to move horizontally in the limit groove 30. When the sleeve 36 contacts the second clamping plate 26, the movable plate 29 is completely pushed into the plate groove 28. At this time, the second electrode sheet 34 on the limit rod 31 contacts the first electrode sheet 33, so that the inner portion of the indicator light 27 is When the circuit is connected, the indicator light 27 sends an electrical signal to the control panel 35. After receiving the electrical signal, the control panel 35 controls the second motor 23 to stop operating. At this time, the first clamping plate 25 stops moving, that is, the first clamping plate 25 pushes the sleeve 36 to move horizontally toward the second clamping plate 26. At the moment when the sleeve 36 contacts the second clamping plate 26, the first clamping plate 25 stops moving. At this time, the clamping force of the first clamping plate 25 and the second clamping plate 26 on the sleeve 36 is moderate, which realizes the adjustment of the clamping force, avoids excessive clamping force to damage the sleeve 36, and is conducive to improving the protection of the sleeve 36;In the process of drilling the sleeve 36, the existing drilling tool cannot accurately adjust the position of the hole, resulting in low drilling accuracy. After the sleeve 36 is clamped and fixed, the knob 7 is turned to drive the first screw rod 6 to rotate, and the first screw rod 6 drives the slider 8 thereon to move horizontally. The slider 8 drives the pointer 14 and the milling cutter 12 thereon to move horizontally. The pointer 14 and the milling cutter 12 move synchronously. According to the scale 13 scale pointed by the pointer 14, the drilling position of the milling cutter 12 is accurately adjusted. After the two milling cutters 12 are accurately adjusted, the two groups of hydraulic cylinders 2 are operated, and the two groups of hydraulic rods 3 drive the two groups of mounting plates 4 to move vertically downward. The two groups of mounting plates 4 drive the first motor, the rotating frame 11 and the milling cutter 12 thereon to move vertically downward. At the same time, the first motor drives the milling cutter 12 to rotate at a high speed. The two groups of milling cutters 12 drill the sleeve 36 quickly. This structure can accurately adjust the drilling position of the milling cutter 12, which is conducive to improving the drilling accuracy. ;
