Description
Technical field
The invention belongs to specific purpose tool, particularly for the instrument of conduit enlarging technology.
Background technology
In helicopter hydraulic system, use enlarging tubes connection widely, the sealing of enlarging conduit ensure that the stable of whole helicopter hydraulic system, if there is hydraulic leak, consequence is hardly imaginable.The enlarging face of conduit must one-shot forming and Glabrous thorn.Original flaring tool is manually enlarging mainly, and the drawback of manual enlarging is firmly uneven, easily makes enlarging break or flaring angle does not reach drawing requirement, has a strong impact on enlarging part quality and working (machining) efficiency.
Summary of the invention
The invention provides a kind of conduit flaring tool, comprise matrix, conical roller, rolling bearing, adjustment pad, lining, plug screw, center cone, steel ball, ball seat, matrix front end adopts cylindrical bore structure, shank adopts Mohs cone shape, the conical surface of matrix rear end has the stepped hole of through matrix, the rear end of stepped hole has screw thread, rolling bearing is installed on the rear portion of stepped hole, conical roller comprises circular cone operate portions and Step Shaft portion, Step Shaft portion coordinates the front portion being installed on stepped hole with rolling bearing, adjustment pad is between conical roller and rolling bearing, rolling bearing comprises front end rolling bearing and rear end rolling bearing, lining is between front end rolling bearing and rear end rolling bearing, plug screw is threaded connection in matrix stepped hole, plug screw contacts with the outer ring of rear end rolling bearing, center cone is positioned on the front end face of matrix, the center line of center cone overlaps with the center line of matrix, the rear end face of center cone contacts with steel ball, steel ball contacts with ball seat front end face.
A kind of embodiment of this conduit flaring tool, also comprises screw, matrix has screw thread stepped hole, and screw coordinates with matrix screw thread stepped hole, and the top of screw contacts with ball seat rear end face.
A kind of embodiment of this conduit flaring tool, also comprises swivel nut, and the external screw thread of swivel nut and matrix screw thread stepped hole screw-internal thread fit, the internal thread of swivel nut coordinates with the external screw thread of screw.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below the present invention is described in further details.See Fig. 1, the present invention includes matrix 1, conical roller 2, rolling bearing 3, adjustment pad 4, lining 5, plug screw 6, center cone 7, steel ball 8, ball seat 9, matrix 1 front end adopts cylindrical bore structure, shank adopts Mohs cone shape, the conical surface of matrix 1 rear end has the stepped hole 1-1 of through matrix 1, the rear end of stepped hole 1-1 has screw thread, rolling bearing 3 is installed on the rear portion of stepped hole 1-1, conical roller 2 comprises circular cone operate portions 2-1 and Step Shaft portion 2-2, ensures the size of flaring angle when its Main Function is enlarging.Step Shaft portion 2-2 coordinates with rolling bearing 3 front portion being installed on stepped hole 1-1, and adjustment pad 4 is between conical roller 2 and rolling bearing 3, and its Main Function is the gap of adjustment conical roller 2 and rolling bearing 3.Rolling bearing 3 comprises front end rolling bearing 3-1 and rear end rolling bearing 3-2, and lining 5 is between front end rolling bearing 3-1 and rear end rolling bearing 3-2, and its Main Function is the gap between adjustment matrix 1 and rolling bearing 3.Plug screw 6 is threaded connection in stepped hole 1-1, and its Main Function prevents conical roller 2 play.Plug screw 6 contacts with the outer ring of rear end rolling bearing 3-2, and center cone 7 is positioned on the front end face of matrix 1, and its Main Function prevents conical roller 2 to be out of shape when enlarging.The center line of center cone 7 overlaps with the center line of matrix 1, and the rear end face of center cone 7 contacts with steel ball 8, and steel ball 8 contacts with ball seat 9 front end face, and its Main Function is the position of adjustment center cone 7.
See Fig. 1, the present invention also comprises screw 10, and matrix 1 has screw thread stepped hole 1-2, and screw 10 coordinates with screw thread stepped hole 1-2, and the top of screw 10 contacts with ball seat 9 rear end face.By the rotation of screw 10, promote ball seat 9 and move forward, ensure the position of center cone 7.
See Fig. 1, the present invention also comprises swivel nut 11, and the external screw thread of swivel nut 11 and screw thread stepped hole 1-2 screw-internal thread fit, the internal thread of swivel nut 11 coordinates with the external screw thread of screw 10.Swivel nut 11 realizes the locking of screw 10 position by internal and external threads.
Using method of the present invention is: when carrying out conduit enlarging, be clipped on the scroll chuck of lathe by needing the catheter cartridge of enlarging, by Mohs cone on matrix 1, flaring tool is arranged on the tail cone of lathe, after clamping completes, start lathe main shaft is rotated, by the handwheel on lathe tail cone, locomotive tailstock cone slowly, the degree of depth of enlarging is ensured by the scale on lathe, rotate to realize enlarging by matrix 1 roller bearing and conduit, namely ensure that enlarging quality turn improves conduit expanding efficiency.
