The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
Such as Fig. 1-2, a kind of horizontal digital-control lathe screw tap extension rod, including collet 2 and nigger 1, the lengthening set
Screw tap interconnecting piece is arranged in 1 one end of cylinder, and 1 other end of the nigger setting is used for the collet interconnecting piece of connecting clip 2, the folder
Collet connecting hole 11 is arranged in the axial of head interconnecting piece, is arranged on the side wall of the collet connecting hole 11 and is connected with collet connecting hole 11
Logical adjustment hole 12；The collet end protruded into inside collet connecting hole 11 is disposed radially perforative collet threaded hole 21, collet
Screw 3 is spirally connected through adjustment hole 12 with collet threaded hole 21.
Nigger 1 connects screw tap 4 and collet 2, by the extension of screw tap 4, and can random converting chuck 2, make
Screw tap 4 may be used on horizontal digital-control lathe or other machining tools.
Adjustment hole 12 is set on nigger 1, by adjusting position of the collet screw 3 on 12 length direction of adjustment hole,
To adjust extending length.
Adjustment hole 12 can control the rectilinear path of screw tap 4 in process, not need lathe synchro-feed, structure letter
Single, vdiverse in function, design is reasonable.
The adjustment hole 12 is set as slotted hole, and in the end of slotted hole, connection opens up mounting hole 13, the mounting hole 13
Aperture be greater than slotted hole width.The adjustment hole 12 is symmetrical arranged two groups centered on 1 central axes of nigger, the folder
Head thread hole 21 extends radially through.The collet screw 3 is set as both ends to the cylindrical body of referred to as straight flange.The collet screw 3
The spacing of two straight flanges is of same size with adjustment hole 12；The diameter of the collet screw 3 is smaller than the diameter of mounting hole 13.
The design of collet screw 3 is matched with the shape of adjustment hole 12, and the diameter of collet screw 3 is less than the straight of mounting hole 13
Diameter makes 3 penetrating mounting holes 13 of collet screw be spirally connected with collet threaded hole 21, then rotary chuck screw 3, makes its straight flange and adjusts
The long side in hole 12 is parallel, and then collet screw 3 drives collet 2 to slide in collet connecting hole 11, to adjust extending length.
The axial setting anti-rotating hole 14 of the screw tap interconnecting piece, setting and anti-rotating hole 14 on the side wall of 4 interconnecting piece of screw tap
The radial hole of connection；The screw tap end that insertion is matched with anti-rotating hole 14 is correspondingly arranged screw-tap threaded hole, and screw tap screw is through radial
Hole is spirally connected with screw-tap threaded hole.The anti-rotating hole 14 is set as square hole or polygonal hole.
Anti-rotating hole 14 is set as square hole or polygonal hole, for providing torque, in the case where screw tap 4 rotates, no
Can be there is a situation where screw tap 4 and 1 relative rotation of nigger, it is reasonable to design.
The collet 2 is set as Morse taper shank 22.The design of collet 2 matches with horizontal digital-control lathe, by Morse taper shank
22 are loaded to horizontal digital-control lathe.
Application method: it by the collet connecting hole 11 of collet end insertion nigger 1, by collet threaded hole 21 and installs
Hole 13 is aligned, and is bolted in collet threaded hole 21 with 3 penetrating mounting holes 13 of collet screw, is made the straight flange and tune of its collet screw 3
The long side of knothole 12 is parallel, and then collet screw 3 drives collet 2 sliding to the direction far from mounting hole 13 in collet connecting hole 11
It is dynamic, to adjust extending length to suitable location；Morse taper shank 22 is snapped fitted on horizontal digital-control lathe；Then nigger 1
The other end screw tap 4 is inserted into anti-rotating hole 14, with screw tap screw fasten.
During tapping, only need numerically-controlled machine tool that collet 2 is driven to rotate, screw tap 4 pierces threaded hole on workpiece, in silk
When boring 4 spirals and going deep into inside workpiece, nigger 1 can be slided using collet screw 3 in adjustment hole 12,1 band of nigger
With collet 2 opposite linear movement occurs for dynamic screw tap 4, i.e., the mounting hole 13 of nigger 1 is to the close shifting in 3 direction of collet screw
It is dynamic；Realize that collet 2 rotates, while nigger 1 drives screw tap 4 mobile to the dimension linear for going deep into inside workpiece, completes screw tap 4
Helical rotation movement；To reduce the active force that numerically-controlled machine tool synchronizes feeding, power output is reduced.
The above is only the preferred embodiment of the utility model only, be not intended to limit the utility model spirit and
Within principle, any modification, equivalent replacement, improvement and so on be should be included within the scope of the utility model.
