Description
Technical field
The present invention relates to clamping tool for machine work technical fields, more particularly to a kind of process for hard tube class elongated shaft part to protect
The turning attachment of card.
Background technique
The hole hard tube part external screw thread M10 × 1-6h is to inner holeConcentricity be φ 0.05, in previous company
In spindle set processing, since part is elongated, and outer circle is screw thread, is not available screw thread positioning process
Inner hole.On the one hand it is easy to damage screw thread, another aspect screw thread tire fit clearance is larger, is unable to satisfy the requirement of concentricity φ 0.05.
So being usually first to be processed using brill, strand processing method Then inner hole is worn with mandrel positioningInner hole carries out screw thread process.Connecting bushing (hard tube) is processed using this method, be easy to cause and draws partially,Inner hole straightness is poor.When using punching axis positioning process screw thread, due to mandrel action length compared with
It is long, it not can guarantee sufficiently small fit clearance (0.01~φ of φ 0.015), it is difficult to meet 0.05 positioning process need of concentricity φ
It wants.In addition, influenced by cutting force, hard tube clamping in process, disassembly are also more difficult, and be easy to pull Inner hole, processing method have much room for improvement.In addition, hard tube material is titanium alloy T C11, more other connections
The processing of axle sleeve copper product is more difficult, becomes the production bottleneck of this part processing.
Summary of the invention
Goal of the invention: a kind of turning attachment guaranteed for the processing of hard tube class elongated shaft part is proposed, to solve in mesh
When preceding progress hard tube class elongated shaft part is processed, the problem of hard tube threaded interior hole precision and concentricity do not reach requirement, simultaneously
To solve the problem of that parts fixation in process, disassembly is difficult and is easy the inner hole pulled.
Technical solution:
A kind of turning attachment guaranteed for the processing of hard tube class elongated shaft part, including stationary center and live center, it is described
Stationary center include fixed main shaft clamping part, retaining element positioning and clamping part and part transmission pin, the fixation
The setting of part positioning and clamping part is movably arranged on solid in fixed main shaft clamping part front end, described part transmission pin one end
Determine main shaft clamping part front end, the revolving center includes standard live center and movable members positioning and clamping part, the work
Dynamic part positioning and clamping part is arranged in standard live center front end.
The standard live center is Morse taper shank.
The fixed main shaft clamping part is also connect with numerically controlled lathe.
The retaining element positioning and clamping part and the fit clearance of outer rigid conduit class elongated shaft inner bore of part are not more than
0.015mm。
The movable members positioning and clamping part and the fit clearance of outer rigid conduit class elongated shaft inner bore of part are also little
In 0.015mm.
It is 0.2mm that, which there are Radius in the retaining element positioning and clamping part, movable members positioning and clamping part root,
Rounded corner.
The utility model has the advantages that proposing a kind of turning attachment guaranteed for the processing of hard tube class elongated shaft part, can preferably keep away
The inner hole for exempting from hard tube class elongated shaft part is pulled, and the clamping deformation of part is reduced, and preferably solves concentricity (Φ 0.05)
Guarantee problem, qualification rate 100% are processed, in addition, the present invention has the spy of quick-clamping, fast quick-detach, not damage reason location inner hole
Point, processing efficiency improve 4 times or more.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is course of work schematic diagram of the present invention；
Wherein: 1-fixed main shaft clamping part, 2-parts are driven pin, 3-retaining element positioning and clamping parts, 4-
Standard live center, 5-movable members positioning and clamping parts.
Specific embodiment
The present invention is further introduced with reference to the accompanying drawing, it is of the present invention a kind of for hard tube class elongated shaft zero
The turning attachment that part processing guarantees, including stationary center and live center, the stationary center include fixed main shaft clamping part
1, retaining element positioning and clamping part 3 and part are driven pin 2, and when processing, part is driven pin 2 and part is driven to rotate (part
End designed openings slot, cuts off in subsequent handling), it eliminates in process and is made due to cutting rotates and increases part axial pressure
At part deformation, the described setting of retaining element positioning and clamping part 3 is in 1 front end of fixed main shaft clamping part, described zero
Part transmission 2 one end of pin is movably arranged on 1 front end of fixed main shaft clamping part, and the revolving center includes 4 He of standard live center
Movable members positioning and clamping part 5, the movable members positioning and clamping part 5 are arranged in 4 front end of standard live center.
The standard live center 4 is Morse taper shank.
The fixed main shaft clamping part 1 is also connect with numerically controlled lathe.
The retaining element positioning and clamping part 3 and the fit clearance of outer rigid conduit class elongated shaft inner bore of part are not more than
0.015mm, the movable members positioning and clamping part 5 and the fit clearance of outer rigid conduit class elongated shaft inner bore of part are also little
In 0.015mm.
The retaining element positioning and clamping part 3,5 root of movable members positioning and clamping part have the Radius to be
The rounded corner of 0.2mm increases part self-centering function.
The course of work: by fixed main shaft clamping part peace 1 loaded on lathe (numerically controlled lathe) main shaft, part trundle is removed
Son 2 guarantees the fit dimension of 3 vehicle of retaining element positioning and clamping part to outer rigid conduit class elongated shaft inner bore of part between cooperating
Gap is not more than φ 0.015mm, it is ensured that stationary center and the lathe centre of gyration are coaxial, load onto part transmission pin 2 later；Live center
Movable members positioning and clamping part 5 also in the 0.048mm margin of tolerance by fit clearance no more than φ 0.015mm grouping plus
Work, and the requirement selection standard live center according to part fit clearance no more than φ 0.015mm, as part is carried out clamping by Fig. 2
Positioning.
The present invention is with hard tube class elongated shaft part datum holeFor positioning datum, using naturally fixed
The mode clamping parts that position clamps, the clamping deformation before reducing part processing, reduce cutting deformation when processing, reduce processing knot
Part removes the deformation of generation from fixture after beam.Meanwhile it being equipped with lesser position gap, guarantee
Concentricity Φ 0.05 requirement of the hole to external screw thread M10 × 1-6h.
The present invention positions the tolerance 0.048mm of inner hole according to part, devises the fit clearance of stationary center and live center,
Stationary center gets on the bus out in lathe spindle and positions outer circle, is subject to self-centering function of the live center on tail stock, it is ensured that zero
Part, stationary center, live center are coaxial on lathe, the composition of stationary center and live center, meet part quick-clamping, positioning and
Disassembling function is verified by batch machining, is preferably solved the processing of hard tube class elongated shaft part and is guaranteed that the guarantee of concentricity is asked
Topic, qualification rate 100%, in addition, the present invention has the characteristics that quick-clamping, fast quick-detach, not damage reason location inner hole, processing efficiency
4 times or more are improved, while the inner hole of hard tube class elongated shaft part preferably being avoided to pull, reduces the clamping deformation of part.
The above embodiments merely illustrate the technical concept and features of the present invention, and the purpose is to allow the skill for being familiar with the technical field
Art personnel can understand the content of the present invention and implement it accordingly, and can not be limited the scope of the invention with this, all bases
