The utility model relates to the technical field of screw tap equipment, and discloses a screw tap with an automatic lubricating
system, which comprises a main body mechanism, a connecting mechanism and an auxiliary mechanism, the main body mechanism further comprises a connecting
pipe, a central control part and a tapping part, and the connecting
pipe is fixedly arranged at the outer end of a detection module and is communicated with a cavity of a screw tap
handle part; the center control part is fixedly installed at the end, away from the detection module, of the connecting
pipe, and the tapping part is fixedly arranged on the outer surface of the screw tap body and used for drilling and laying threads. The screw tap body is fixedly connected with the
machine tool transmission
assembly in a clamped mode through the screw tap
handle part, the detection module correspondingly compares the rotating speed of the screw tap body with the tapping pressure value, when
lubrication is insufficient, the center control part extracts lubricating liquid to enter the screw tap
handle part through the connecting pipe, the lubricating liquid evenly fills the tapping part under the action of
centrifugal force and gravity, and the tapping effect is improved. Therefore, friction is reduced, abrasion is reduced,
machining precision is improved, and the service life of the screw tap is prolonged.
