Description
Technical field
It the utility model is related to field of machining, and in particular to a kind of combined type for numerically controlled lathe is adjustable internal expanding core
Axle clamp has.
Background technology
At present, there is the pipe part of axiality requirement for both ends endoporus, how to ensure the axiality of hole machined in both ends
It is required that be always the problem that faces of industry, currently used method have lathe both ends process respectively with machining center Four-axis milling,
Clamping precision need to be transmitted with external diameter using first method, because clamping error need to beat table centering, extremely inefficient and quality is very unstable
It is fixed, be not suitable for stable mass production, Four-axis milling equipment, equipment cost and work time cost need to be put into using second method
Height, bore hole efficiency is low compared with lathe, and economy is bad, while because four axles rotate repetitive positioning accuracy problem, the production higher to precision
Product, ensuring coaxiality are still more difficult.Conventional expansion force central spindle is because tighter to size tolerance requirements at endoporus clamping, because of pipe orifice clamping
Locate undressed, tolerance can not reach the requirement of clamping standard, and every kind of mandrel can only adapt to the scope of very little, poor universality, make
The shortcomings that valency is high.

Fixed by support unit, the thimble is connected with the main shaft and tailstock of numerically controlled lathe respectively, and the support shaft is single by connecting
Member is connected with the main shaft of Digit Control Machine Tool.
The outer surface of described support shaft is threaded, and is threaded, and more can accurately realize the shifting of support unit
It is dynamic and fixed.
Rate taper nut that described support unit includes being threaded in support shaft, rising core and locking nut and is arranged
Ringfeder on the outside of the core that rises, the side of the core that rises is provided with the bellmouth of indent, and the side wall of bellmouth is provided with and rate taper nut
Match screw thread, and the locking nut is connected in support shaft and abutted with the opposite side for the core that rises, during work, the rate taper nut
Screw in bellmouth, strut rise core and ringfeder, until ringfeder abuts with the inwall of workpiece to be processed.
The quantity of described support unit is at least 2.
Described connection unit is heart carrier for bolt, and the driver plate of the main shaft of the heart carrier for bolt and Digit Control Machine Tool connects.
Described thimble is included with supporting the tapering of axis connection and being arranged on the connecting portion of tapering tail end, two thimbles
Connecting portion is connected with the main shaft and tailstock of numerically controlled lathe respectively.
Operation principle of the present utility model is as follows：The Fast Installation of fixture and Digit Control Machine Tool is realized by two thimbles, is loaded and unloaded
Easily and positioning precision is high, and carrying dynamic support shaft secretly by chicken core rotates, so as to passing power, all screw threads in the middle part of support shaft
Structure, both ends clamp system are completely independent work, and axial location can be adjusted flexibly by rotary expansion core, after position mixes up, pass through
After adjustment locking nut locks the position, you can clamping workpiece, and both ends rotate rate taper nut and elastic expanding core external diameter is risen respectively
Greatly so as to clamp workpiece to be processed endoporus, because adjustment Support Position is avoided in processing at stepped hole, so two end faces and
Stepped hole can a turnery processing completion in both ends.So as to ensure that the very high depth of parallelism of both ends of the surface and very high same of two endoporus
Axle degree.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects：
(1) it is clamped one time to change traditional clamping twice, and quality is more stable, improved efficiency.
(2) change plain clamp poor universality, the small limitation of the scope of application, pass through rotational lock nut and elastic expanding
Core, realize different position lengths and adapt to the workpiece needs of different length.
(3) by increasing the ringfeder of various outer diameter, the extension of different pore size is realized.
(4) by selecting the support shaft of different length, so that it may adapt to the needs of different bearing length workpiece, support shaft significantly
Cost it is more conventional change mandrel cost, reduce highly significant, at least cost be reduced to only need 1/10th a cost.
(5) by changing the support shaft of different length and the regulatory function of support shaft itself screw thread, different length can be achieved
Combination, by selecting the ringfeder of various outer diameter to realize the combination of different-diameter so that poor universality and cost it is high and
The conventional arbor of manufacturing cycle length, which is changed into, realizes Rapid Combination, good economy performance, adaptable combined core-axle.
(6) both ends of the surface and interior stepped hole can be machined with clamped one time, stepped hole in the depth of parallelism of both ends of the surface and two
Axiality can ensure very high precision and with stable quality.
