The inner face of side fits with outer end of the cone face, so that screw tap ontology can determine left and right sliding, the left side of the positioning sleeve in set
With the support ring that lateral extension is formed, the drive sleeve is sheathed on transmission segment outer peripheral surface, left side and positioning sleeve
Rear end is fixedly connected with, and right end extends on terebrantia, and is in contact with the outer surface of terebrantia, on the inner surface of the drive sleeve
With the guide thread section matched with motion thread, several dregs guiding grooves are offered on the positioning sleeve.
The technical effect of the utility model are as follows: in order to improve the steering capability of screw tap, it is fixed to be equipped with outside traditional screw tap
Position set, when screw tap is in the state of not yet working, conehead is in positioning sleeve, in machining internal thread, positioning ring front end
Support ring circle play a supporting role, the stress of conehead can be effectively reduced, simultaneously as on screw tap ontology have transmission segment,
The movement of transmission segment can not only provide power, also help to effectively reduce the circumferential play of screw tap, improve machining accuracy.
In a kind of above-mentioned machine tap, the front end of the support ring has tapered guide edge.Pass through guiding
While the stationkeeping ability of support loop edge can be improved.
In a kind of above-mentioned machine tap, the length of the guide thread section is longer than the length of motion thread.It can help
Stroke length when improving tap tapping is helped, the range of processing is improved.
In a kind of above-mentioned machine tap, the horizontal plane of the dregs guiding groove and positioning sleeve is arranged in an oblique way.Be conducive to
More easily chip removal.
In a kind of above-mentioned machine tap, it is connected between the positioning sleeve and drive sleeve by screw thread.Conveniently tear open
Dress, improves the efficiency of installation and removal, is conducive to timely check and safeguard.
In a kind of above-mentioned machine tap, several anti-skidding muscle are set on the outer end face of the drive sleeve, each described
Anti-skidding muscle is distributed along the length direction of drive sleeve.When drive sleeve is fixed, can help to reduce opposite turn of drive sleeve
Dynamic bring influences.
Compared with prior art, this machine tap is equipped with positioning sleeve and drive sleeve on the basis of traditional screw tap, passes through
Positioning sleeve promotes guiding performance and transmission accuracy with drive sleeve.Have the advantages that guiding performance is good, machining accuracy is high, stability is strong.
