Description
Technical field
The utility model is related to hollow axis machining apparatus, the dress on more particularly to a kind of lathe for processing taper hole hollow shaft
Clamp device.
Background technology
Taper hole hollow shaft is internally provided with the axle part of the axially extending bore with taper, as shown in figure 1, it is in axis body 101
Axis centre on be formed with an axially extending bore 102 with taper.Such taper hole hollow shaft part needs processing excircles face, processing
When parts fixation is fixed on lathe, as shown in Fig. 2 cone rod 201 has the taper being adapted with taper hole hollow shaft, cone rod
Length is slightly less than taper hole hollow shaft, and the left end of cone rod is equipped with and is offseted clamper 202, the right side of taper hole hollow shaft with taper hole hollow shaft
Side is provided with to be installed on lathe final quotaion component and holds out against disk 301, and driving holds out against disk and held out against to the hydraulic pressure that taper hole hollow shaft presses
Cylinder 401.During work, taper hole hollow shaft part is enclosed within cone rod, and holding out against cylinder drive by hydraulic pressure holds out against disk in part right-hand member
Face applies plane pressure so that the internal taper hole of part is close to the male cone (strobilus masculinus) of cone rod, while the left side of part offsets with fixture
Tightly, causing that they turn into by this kind of active force for mutually pushing against can be while the entirety for rotating, and then machine tool chief axis pass through again
Drive fixture to rotate and cause parts turn, coordinate cutter to complete the turnery processing of periphery with this.
The fixation of above-mentioned taper hole hollow shaft by fixture, bore rod and hold out against disk and the direct effect of part is realized, hydraulic pressure
Hold out against cylinder and machine tool chief axis and then apply axial force and circumferential active force indirectly by holding out against disk and fixture, wherein, vertebra
Body is non-removable overall structure with fixture, and fixture is then fixed by flange assembly and bolt fastener with machine tool chief axis and connected
Connect.Thus, when needing to process the taper hole hollow shaft part of different length, it is necessary to which fixture is disassembled from machine tool chief axis,
Then fixture and cone rod with dimension, then the clamping for carrying out taper hole hollow shaft part are changed.This kind of installation way is main
There is problems with.
1st, when need processing part or previous part to machine and when needing to change next part, either part
Feeding or blanking, be required for tailstock tool longitudinal direction（It is in the same direction with main-shaft axis）Move afterwards and reserve clearance position, then part is moved
Just it is capable of achieving to cone rod right side.This requires going-back position of the tailstock tool guide rail it is necessary to have more than one times of part, could be smoothly
The clearance position of part loading and unloading is reserved, the length for thus causing complete machine tool is big, volume is big, while floor space is wide.
2nd, situation such as more ibid, if not increasing lathe volume, can select part and fixture, bore the whole of rod three
Body is disassembled, and is reinstalled again after renewal part, but this has to repeatedly assemble and disassemble machine tool chief axis and fixture, and between them
It is to be connected by flange, dismounting extremely inconvenience will cause operation inconvenient, the non-cutting time needed for greatly increasing processing,
Cause operating efficiency low.
3rd, part is fixed and is placed on cone rod, and both greatly, are connected by taper-face contact, this kind of contact area of connected mode
Intensity is higher, causes part to be difficult to be removed from cone rod, if being beaten from side by aid and being easily damaged part, operation
It is cumbersome.
The content of the invention
The utility model aims to provide a kind of clamping device of the lathe for processing taper hole hollow shaft, to reduce clamping difficulty,
Process time is reduced, the convenience of operation is improved, while improving positioning precision and crudy.
Taper hole hollow shaft clamping device for processing described in the utility model, including the cone being engaged with taper hole hollow shaft part
Rod, wherein one end for boring rod is equipped with pinching end, and the self-adjustable main shaft self-centering chuck in axle center is housed on lathe, and main shaft is made by oneself
One end of heart chuck is connected with machine tool chief axis and be fixedly clamped for pinching end by the other end, and the external peripheral surface of pinching end is additionally provided with outward
Screw thread, back-up ring is movably attached to the surface of pinching end by screw thread pair.
Taper hole hollow shaft clamping device for processing described in the utility model, cone rod has adaptable with taper hole hollow shaft part
Taper, consistent with prior art, but be installed on the pinching end of cone rod one end with external screw thread, back-up ring can be moved by screw thread pair
Move to the optional position of pinching end, in addition, self-centering chuck be a kind of claw can radial concentric movement and make workpiece self-centering
Chuck, it only needs to snap in pinching end in the claw in chuck with the connection of pinching end.Main shaft self-centering chuck is consolidated
Part, when taper hole hollow shaft part is processed, is inserted in cone rod by Dingan County loaded on lathe, and the pinching end for boring rod then is snapped in into master
Axle self-centering chuck, main shaft self-centering chuck can automatically adjust the shaft core position of cone rod and part, be allowed to match somebody with somebody with machine tool chief axis
Close, then, the final quotaion component of the lathe other end applies axial thrust and fixes it to part, finally, rotate back-up ring make its to
One side shifting of main shaft self-centering chuck, until back-up ring is pushed against in main shaft self-centering chuck, thus completes the feeding work of part
Make；When part is machined needs blanking, rotate back-up ring and be allowed to be unclamped with main shaft self-centering chuck, while final quotaion component stops
Apply axial force and unclamp corresponding part one end, then main shaft self-centering chuck is decontroled and cone rod pinching end is consolidated
It is fixed, you can overall to remove cone rod and part, then remove part again from cone rod and complete blanking work.This kind of clamping device leads to
Cross main shaft self-centering chuck fixed cone rod, although needed also exist for during blanking while removing cone rod, but its assembly and disassembly operations is extremely simple
It is convenient, the non-cutting time needed for can effectively reducing processing work, there is provided operating efficiency；Meanwhile, so that equipment is without setting
The clearance position of part is unloaded, equipment volume is effectively reduced；Furthermore, cone rod pinching end is provided with back-up ring, by back-up ring during fixed cone rod
Pushed against with main shaft self-centering chuck, back-up ring can be made to possess the function of nut, increased between cone rod and main shaft self-centering chuck
Bonding strength, is effectively ensured crudy, and when part is unloaded, back-up ring can be moved to part direction, until being pushed against
The side of part, on the one hand applies axial thrust by mutually pushing against, and axial rotation forces are on the other hand applied by friction,
By the effect of the two power so that part is extremely easily unloaded from cone rod, both improves operation ease, is also effectively protected
Card part is against damages.
