First, what is the reason why the impact drill does not impact

Impact drill is a commonly used drilling tool, the use of the internal shaft of the gear beat each other to achieve impact, in the process of use, sometimes there will be impact drill only turn not impact

Hit the situation, what's going on? The reasons why a percussion drill does not impact may be:

1. The impact CAM and spindle are detached

Some impact drill design has two modes, and stability and vibration impact two, and designed with vibration impact CAM, if the impact CAM and the spindle are separated, naturally can not vibration

Dynamic impact, single mode impact drill, impact CAM broken or detached from the spindle, of course, can not vibrate impact.

2, the power supply contact is poor

The poor contact of the power supply may be the cause of the carbon brush, or it may be the reason of the wire. The power socket using the hammer drill must be equipped with a leakage switching device, and check whether the power cord is available

When the hammer drill is found to leak electricity, abnormal vibration, high heat or abnormal sound during use, the work should be stopped immediately and the electrician should be checked and repaired in time.

3, the piston is short of oil

In the case of lack of lubricating oil, the hammer drill will only turn without impact, you can unscrew the handle of the hammer drill and the back screws, and then check whether there is a lack of lubrication inside

Oil, add an appropriate amount of lubricating oil.

4, piston ring or cylinder damage leakage

As the machine rotates, the high air pressure gives the drill bit an instant impact. Piston ring or cylinder damage leakage can not produce high pressure, resulting in no impact;

Therefore, the piston and hammer seal should be good, too tight and too loose.

5, the front of the swinging bearing has a shaft top on the housing

The piston moves back and forth in the cylinder under the transmission of the crankshaft, and if the crankshaft is atop the housing, it will also cause the withdrawal of the hammer drill.

Second, how to maintain and maintain the charging percussion drill

In order to avoid the frequent failure of the hammer drill, it is necessary to do a good job in the maintenance of the hammer drill, which is also conducive to extending the service life of the tool

Attention:

1, by professional electricians regularly replace the hammer drill carbon change brush and check the spring pressure.

2, ensure that the whole body of the impact drill is intact and clean and dirt removal, to ensure that the impact drill is smooth.

3, by professional personnel regularly check whether the parts of the hand electric drill is damaged, serious damage and can not be used should be replaced in time.

4. Timely supplement the body screw fasteners lost on the fuselage during the operation.

5. Regularly check whether the bearings, gears and cooling blades of the transmission part are flexible and intact, and fill lubricating oil to the rotating parts in a timely manner to extend the service life of the hammer drill.

6, after the use of the hammer drill should be promptly returned to the tool library for safekeeping.
