Common Fault Analysis and Solutions for Rocker Drills

Drilling machine is a wide-ranging machine tool, mainly used for drilling, opening, reaming, boring, tapping and scraping plane and other forms of processing. There are many types of drills, there are desktop drills, vertical drills, rocker drills, multi-axis drills, horizontal drills and CNC drills. In a variety of drills, rocker drill ingon is one of the most common drilling equipment, easy to operate, flexible, wide range, especially suitable for single or batch production with porous large workpieces hole processing, rocker drill main function movements to achieve the handle, button and other operating parts concentrated on the spindle box. During the use of the rocker drill often encounter a variety of failures, affecting production.

Fault one: Press the start button the main motor does not turn.

Fault analysis:

The total power switch is not switched on;

The start button is not in good contact;

The contactor does not pick up, the main motor junction box and the wiring in the electrical disc do not touch well or the connector comes off.

Solution:

Turn on the total power switch;

Check the start button connector;

Check the contactpoints in the electrical cabinet.

Check the wiring where the motor is connected.

Fault two: the spindle and the outer surface of the oil leakage phenomenon.

Fault analysis:

The oil in the mailbox is filled with too much and leaks from the top of the housing.

Solution:

Do not allow the amount of oil to exceed the mark in the center of the oil label when filling oil.

Fault 3: Spindle box clampis is not tight.

Fault analysis:

The 55-degree rail surface, which is joined by the spindle box and the rocker arm, has a large gap;

The clamping block position of the spindle box is not correct;

the clamping cylinder is leaking oil at the joint with the brake frame or the oil is leaking at the relevant place;

The diamond block is not rich enough to make it stand up and lock itself.

Solution:

Adjust the screw so that the 55-degree rail surface should not be greater than the clearance of 0.04mm;

In the release state, release the screw adjustment clamping block to the appropriate position to tighten the screw.

The above is the rocker drill ingress the most common three kinds of simple analysis and treatment method, simple fault self-troubleshooting solution not only can save maintenance costs, but also will not delay production.
