The bottom of the rod body 710 is fixedly connected with an arc ball 713, and the top of the arc ball 713 is fixedly connected to one end of a spring B711, and the other end of the spring B711 is fixedly connected to the bottom of the inner tube 709. The arc ball 713 is moved downward by the force of the spring B711, so that the arc ball 713 drives the rod body 710 and the closed ball 712 to move downward at the same time, maintaining the closing effect of the closed ball 712 on the inner tube 709. The top of the rod body 710 is fixedly connected with the closed ball 712, and the outer wall of the sprocket B607 is fixedly connected with an arc push rod 703.

The inner wall of the moving plate 802 is slidably connected to a handle 803. When the position of the moving plate 802 needs to be changed, the handle 803 needs to be moved outward first. By pulling, the handle 803 is released from the plug-in fixing effect on the fixed rod 801, and the outer wall of the handle 803 is fixedly connected to one end of the spring A804, and the other end of the spring A804 is fixedly connected to the inner wall of the movable plate 802, and the force of the spring A804 drives the handle 803 to move inward, so that the handle 803 maintains the plug-in fixing effect on the fixed rod 801, and the outer wall of the handle 803 is plugged into the inner wall of the fixed rod 801, so as to achieve the effect of fixing the lateral position of the movable plate 802 on the fixed rod 801.

[0050] S4. At the same time, during the transmission and movement of the chain 606, the outer wall of the chain 606 contacts the outer wall of the soft brush 706, and the outer wall of the sprocket B607 drives the arc push rod 703 to rotate, so that the outer wall of the arc push rod 703 squeezes the outer wall of the arc ball 713, so that the arc ball 713 drives the rod body 710 and the closed ball 712 to move upward, so that the bottom of the metering cylinder 708 is opened, and the lubricating oil moves downward along the metering cylinder 708 to the inner tube 709, and is transmitted to the hard tubes 704 arranged on both sides through the inner tube 709, and the lubricating oil is transmitted to the outer wall of the soft brush 706 through the hard tube 704, so that the chain 606 is affected by the smearing effect of the soft brush 706 when passing through the soft brush 706, and the lubricating oil is smeared on the outer wall of the soft brush 706, thereby achieving a self-lubricating effect;

Active lubrication: Before use, the staff can pull the handle (803) outward to release the plug-in fixing effect of the handle (803) on the fixing rod (801), and move the movable plate (802) laterally to make the movable plate (802) drive the fixing frame (705) and the metering cylinder (708) to move laterally at the same time, so that the metering cylinder (708) is affected by the arc surface of the wave rod (902) during the lateral movement, so that the arc ball (713) provided at the bottom of the metering cylinder (708) is squeezed and pushed, and the arc ball (713) is pushed. The ball (713) drives the rod body (710) and the sealing ball (712) to move upward, so that the bottom of the metering cylinder (708) is opened, so that the lubricating oil moves downward along the metering cylinder (708) into the inner tube (709), and is transmitted to the hard tubes (704) arranged on both sides through the inner tube (709), and the lubricating oil is transmitted to the outer wall of the soft brush (706) through the hard tube (704), so that the soft brush (706) smears the lubricating oil on the outer wall of the chain (606) when passing through the chain (606), thereby achieving an active lubrication effect; S3. Start the drilling bit to rotate: start the motor B (602) and the motor C (603), so that the output shaft of the motor B (602) drives the sprocket A (604) to rotate, so that the sprocket A (604) drives the drilling bit (605) set at the bottom to rotate, and at the same time, the motor C (603) provides additional rotational force to the sprocket A (604) through the sprocket B (607) and the chain (606), thereby improving the punching force and effect of the drilling bit (605); S4. Automatic lubrication operation: During the transmission and movement of the chain (606), the outer wall of the chain (606) contacts the outer wall of the soft brush (706), and the outer wall of the sprocket B (607) drives the arc push rod (703) to rotate, so that the outer wall of the arc push rod (703) squeezes the outer wall of the arc ball (713), so that the arc ball (713) drives the rod body (710) and the sealing ball (712) to move upward, so that the bottom of the metering cylinder (708) is pressed. The lubricating oil is opened so that the lubricating oil moves downward along the metering cylinder (708) into the inner tube (709), and is transmitted through the inner tube (709) to the hard tubes (704) arranged on both sides, and the lubricating oil is transmitted to the outer wall of the soft brush (706) through the hard tube (704), so that the chain (606) is affected by the smearing effect of the soft brush (706) when passing through the soft brush (706), and the lubricating oil is smeared on the outer wall of the soft brush (706), thereby achieving a self-lubricating effect; S5. Dual-drive punching work: Then start the hydraulic rod (5), so that the hydraulic rod (5) drives the drilling drill (605) to descend, so that the drilling drill (605) descends to punch the spray plate placed on the top of the workbench (1); S6. Spray plate blanking: take out the spray plate after punching, so as to achieve the punching processing effect of the spray plate.
