Maintenance and adjustment of radial drilling machine

(1) Adjustment of feed safety clutch

Open the upper right panel of the spindle box, adjust the round nut A to increase or decrease the pressure of the spring D, so that the spindle feed resistance reaches the specified value. This mechanism has been measured by the manufacturer and sealed by the manufacturer before leaving the factory. Users cannot easily Adjustment. If adjustment is really needed, it must be carried out by professionals with experience in drilling machine use. If this is not the case, the damage to the parts caused by the accident is the responsibility of the user.

(2) Adjustment of spindle balance force

Remove the limit block at the outer end of the rocker arm, move the spindle box outside until the balanced spring box is exposed, use a tool to hold the spring box, remove the limit screw, rotate the spring box to the proper position, use the screw to limit, test Balance the situation until it is suitable.

(3) Adjustment of rocker arm lifting safety device

1) The safety device is slipping, and the rocker arm cannot be raised and lowered normally. It is necessary to remove the observation cover behind the shell, pry off the non-return washer on the intermediate shaft, and adjust the round nut to the proper position (safety torque is about 10-12Nm) (Guide: An automatic riveting processing method for stamping parts)

2) When the rocker arm rises or falls to the two extreme positions, the insurance fails. If the friction torque is greater than the maximum torque of the motor and it fails, adjust the nut to reduce the friction torque.

Maintenance of radial drilling machine

(1) Before using the radial drilling machine, the anti-rust oil and its grease should be removed from all places, so as not to affect the flexibility of the action.

(2) When the radial drilling machine is in use, it should be lubricated and adjusted according to the various regulations in the manual.

(3) The rocker arm and column guide rails should be cleaned frequently with a gauze cloth and filled with oil to avoid scratches.

Accuracy of radial drilling machine: 1. Verticality: The vertical 200mm between the main shaft of the drilling machine and the working table of the drilling machine allows a difference of 0-0.05mm. 2. Parallelism: The spindle box enters and exits along the rocker arm left and right, and the rocker arm moves back and forth with the column. The parallelism is 200mm and the tolerance is 0-0.1mm.
