Description
Technical field
The utility model belongs to machine tool technology field, and in particular to a kind of fixture of digital controlled processing central machine tool.
Background technique
With the fast development of mechanical processing industry, numerically controlled processing equipment increasingly tends to automation and intelligence, is cutting
It cuts more more and more universal in processing.However it is upper in machining center carry out in cutting process, due to cylindrical surface and spherical configuration
Complicated Box-body Parts are not easy to clamping, and machine tool accessory is difficult to effectively clamp workpiece, such as parallel jaw etc., V-type vice
Application is not extensive due to clamping range is limited again, in view of the particularity of External Shape, it is often necessary to by means of Special tooling clamp,
Lead to many kinds of of frock clamp, number increases.Design specialized frock clamp for single-piece and parts in small batch processing for,
Processing charges is not only increased, and extends the production cycle.Processing the simple approach that such part uses at present is directly will
Lathe chuck is placed in machining center on workbench, then with clamping chuck part.Often due to processing center machine tool workbench with
Universal machine tools attachment interface mismatches, and chuck can only be directly born against on work top, keeps the two relatively quiet by frictional force effect
Only, chuck both delocalization or had not been felt relieved, and also needed to repeat centering before processing, and for a long time under by cutting force operative condition,
Chuck is easy to loosen and slowly creep with respect to workbench, and not noticeable displacement occurs, does not reach requirement Product Precision, quality is not
It is high, unstable.
Utility model content
The purpose of the utility model is to provide a kind of fixtures of digital controlled processing central machine tool, solve Special tooling clamp
Type and number are various, realize chuck positioning and centering, the process-cycle of shortening, improve machining accuracy.
The technical solution of the utility model is, a kind of fixture of digital controlled processing central machine tool includes ontology, conical core shaft, core
Axis, directional bond, screw and chuck；Conical core shaft is periphery conical core shaft；
One end of mandrel is fixed on centre bore one end of ontology, and the centre bore that one end of conical core shaft is fixed on ontology is another
One end, directional bond are fixed by screws in the bottom surface locating slot of ontology, and chuck is sleeved on the other end periphery of conical core shaft,
Chuck is fixedly connected by bolt with ontology, and ontology is positioned and fixed with platen by mandrel and directional bond and connect.
The utility model has the beneficial effects that 1, the utility model realizes processing center machine tool workbench and universal lathe
The connection of chuck realizes the different size T-slots such as Multiple Type vertical machining centre, horizontal Machining centers, digital-control boring-milling machine
Workbench is connected with the combination of the three-jaw, four paws lathe chuck that make different size, overcomes classical machine tool accessory and automatic numerical control
The difference of machining center equipment interface becomes the bridge for linking up traditional clamp method and modern multi-shaft interlocked lathe；2, this is practical
New type fittings structure is simple, is common material, thermally treated, and conventional equipment can complete the process；Selection standard part is logical
With standard component, buying is easy, and assembly is simple and easy, convenient for disassembly and assembly；3, it can not only be reached using the utility model and be mentioned
High efficiency can improve product quality, reduce the purpose of production cost, can also really realize the cost efficiency of production process；
4, for the utility model by ontology bottom surface keyway and platen T-slot directional bond and threaded connection, connection is effectively and steady
Gu；By lathe chuck center taper hole and ontology spindle taper forms taper fit and screw threads for fastening connects, and concentricity is high；
It is cooperatively connected, is located by connecting reliable, concentricity is high with mandrel by body apertures and table core；Joined by lathe chuck claw
Dynamic clamping workpiece, clamping force are big；Workpiece centre, chuck hub, platen absolute coordinate center, three-core are overlapped, registration
It is high；Workpiece centre, the machine tool chief axis centre of gyration, platen absolute coordinate center, three is concentric, and can quickly feel relieved,
Repeatable accuracy is high；5, multiplexing can be realized by clamped one time to cylindrical surface and dome shape and class cylindrical surface and dome shape workpiece
Sequence concentrated processing, versatility, practical, at low cost, good manufacturability.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the fixture of digital controlled processing central machine tool of the use of the new type；
Fig. 2 is the sectional view along A-A of Fig. 1.
Specific embodiment
The technical solution of the utility model is described in further detail with reference to the accompanying drawings of the specification.
As depicted in figs. 1 and 2, a kind of fixture of digital controlled processing central machine tool of the utility model includes ontology 1, conical core shaft
2, mandrel 3, directional bond 4, screw 5, T-bolt 6, washer 7, nut 8 and hexagon socket cap head screw 9.Conical core shaft 2 is periphery
Conical core shaft.Chuck uses universal lathe chuck.
One end of mandrel 3 is fixed on centre bore one end of ontology 1, and one end of conical core shaft 2 is fixed on the centre bore of ontology 1
The other end, directional bond 4 are fixed in the bottom surface locating slot of ontology 1 by screw 5.Chuck is sleeved on the other end of conical core shaft 2.
Chuck is fixedly connected by bolt with ontology 1.Ontology 1 by mandrel 3 and directional bond 4 and table positions, and by bolt with
Workbench is fixedly connected.
Assembling process uses socket cap firstly, being positioned with spindle taper 2 by lathe chuck center taper hole and the cooperation of ontology 1
The interior connection of six square bolt 9 fastening；Secondly, being felt relieved with mandrel 3 by the hole of ontology 1 and the cooperation of table core counterbore；Finally, with
Directional bond 4 connects the bottom surface keyway and platen T-slot of ontology 1, connects fastening with T-slot bolt 6 and with shoulder nut 8.
So far, chuck jaws holding parts can be unclamped, are programmed, cutter is selected to carry out part processing.
