Summary of the invention
The present invention will provide a kind of smooth turning lathe collet adjustable interior locating device, in collet indoor design " adjustable device decided at the higher level but not officially announced ", this device is installed to the centre of collet afterbody, adopt this collet being configured with positioner, the axial dimension of its workpiece controls convenient, effective, reliable, the every workpiece selecting collet to clamp of its function of form, can implement axial location effectively reliably.
For achieving the above object, technical scheme of the present invention is: the adjustable interior locating device of a kind of smooth turning lathe collet, comprise tapering swivel nut, opening tapering sleeve pipe, locking nut, positioning screw, adjusting nut, positioning screw is threaded connection in described tapering swivel nut, be rotary with adjusting nut between positioning screw rearward end and tapering swivel nut rear end face, the internal thread of adjusting nut coordinates with the external screw thread of positioning screw; The male cone (strobilus masculinus) of described tapering swivel nut is connected opening tapering sleeve pipe, the rearward end of described tapering swivel nut is threaded connection locking nut, opening tapering sleeve pipe for promoting to coordinate with tapering swivel nut outer cone moves, change the little outside diameter size of opening tapering sleeve pipe, so that produce tight fit with the afterbody endoporus of collet, axial location locks.
The profile of described tapering swivel nut is cylindrical, and the axial centre of tapering swivel nut is provided with tapped through hole, and outside is provided with tapered section and cylindrical section, and described cylindrical section is positioned at the small end side of tapered section, and cylindrical section is provided with external screw thread.
The profile of described opening tapering sleeve pipe is cylinder step, and inner chamber is taper hole, and its internal taper numerical value is consistent with the external taper numerical value of tapering swivel nut; The little cylindrical axial length of the cylinder step of described opening tapering sleeve pipe is in the axial length of large cylindrical, the axis of described opening tapering sleeve pipe has side tube wall milling and wears groove, form radial non-close cast, diameter under the little cylindrical free state of described opening tapering sleeve pipe is less than the afterbody endoporus of collet, and the shoulder height drop between large and small cylindrical is less than the afterbody wall thickness of collet.
Beneficial effect of the present invention:
Apparatus structure of the present invention is simple and easy, compact, practical, cost of manufacture is low, and in production practices, shows convenient mounting and clamping, flexible operation, and can adapt to various axial workpiece, precision is high, effectively can ensure the length dimension requirement of required processing parts.This device, by collet preparation position-limit mechanism, solves the defect of collet axial location difficulty, improves quality and the efficiency of parts batch processing.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of the adjustable interior locating device of smooth turning lathe collet of the present invention;
Fig. 2 is the structural representation that device of the present invention is arranged in collet.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As Fig. 1, shown in 2, the adjustable interior locating device of a kind of smooth turning lathe collet, comprises tapering swivel nut 1, opening tapering sleeve pipe 2, locking nut 3, positioning screw 4, adjusting nut 5.
Positioning screw 4 is threaded connection in tapering swivel nut 1, adjusting nut 5 is rotary with between positioning screw 4 rearward end and tapering swivel nut 1 rear end face, the internal thread of adjusting nut 5 coordinates with the external screw thread of positioning screw 4, for adjusting the span access location length that dog screw 4 screws out from locking nut 3; The male cone (strobilus masculinus) of tapering swivel nut 1 is connected opening tapering sleeve pipe 2, the rearward end of tapering swivel nut 1 is threaded connection locking nut 3.
The profile of tapering swivel nut 1 is cylindrical, and the axial centre of tapering swivel nut 1 is provided with tapped through hole, and outside is provided with tapered section and cylindrical section, and described cylindrical section is positioned at the small end side of tapered section, and cylindrical section is provided with external screw thread.
The profile of opening tapering sleeve pipe 2 is cylinder step, and inner chamber is taper hole, and its internal taper numerical value is consistent with the external taper numerical value of tapering swivel nut 1; The little cylindrical axial length of the cylinder step of opening tapering sleeve pipe 2 is in the axial length of large cylindrical.The axis of opening tapering sleeve pipe 2 has side tube wall milling and wears groove, form radial non-close cast, diameter under the little cylindrical free state of opening tapering sleeve pipe 2 is less than the afterbody endoporus of collet 8, and the shoulder height drop between large and small cylindrical is less than the afterbody wall thickness of collet 8.
Locking nut 3 is counterparts of tapering swivel nut, coordinate with the external screw thread of tapering swivel nut 1, its function is that the opening tapering sleeve pipe 2 promoting to coordinate with tapering swivel nut 1 outer cone moves, change the little outside diameter size of opening tapering sleeve pipe 2, so that produce tight fit with the afterbody endoporus of collet 7, i.e. axial location locking.
The similar special long spiro nail of positioning screw 4 profile, the screw-internal thread fit of its external screw thread and adjusting nut 5.
The internal thread of adjusting nut 5 coordinates with the external screw thread of positioning screw 4, the span access location length that adjustable dog screw 4 screws out from locking nut 3.
As shown in Figure 2, the assembling of adjustable device decided at the higher level but not officially announced and installation method as follows:
