Abstract
The utility model discloses a fixture for a computer numerical control machining center. The fixture comprises a locating shaft, a substrate, a thin-wall jacket and a medium and is characterized in that the substrate is fastened to the locating shaft through screws; the substrate is in interference fit with the thin-wall jacket; the medium is arranged in the substrate and the thin-wall jacket; under the action of downward pressing force of a screw on the top of the substrate, the medium expands the outer wall of the thin-wall jacket, so that a workpiece is fastened to the thin-wall jacket. The fixture is simple in structure, convenient to assemble and disassemble, accurate in correction and easy and convenient to mount and can be applied to small scale production of compressor cylinder sleeves, bearing bushes, special-shaped cylindrical workpieces and the like, the parts are clamped and machined at a time on the computer numerical control machining center, the machining accuracy is improved and errors caused by repeated clamping are reduced.
Description
Technical field
The utility model relates to a kind of numerical control machining center fixture.
Background technology
The cylinder type workpiece such as compressor cylinder sleeve, bearing shell lining, special-shaped cylinder sleeve, there is the plane of difform groove and different angles at its end face or middle part, in small batch production process, conventional equipment can not clamped one time, size is all machined, along with the lifting of numerical control equipment, most of numerical control machining center that adopts is processed.The utility model relates to a kind of numerical control machining center fixture, the cylindrical special-shaped workpiece such as compressor cylinder sleeve, bearing shell lining, special-shaped cylinder sleeve are carried out to clamped one time, the groove of all brills, milling, different angles and plane equidimension are processed at one time, reduce mismachining tolerance and multiple clamping cumulative errors, thereby enhance productivity and machining accuracy.
Summary of the invention
The utility model provides a kind of numerical control machining center fixture, simple in structure, easy to loading and unloading, calibrate the features such as accurate.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of numerical control machining center fixture, comprise locating shaft, matrix, thin-wall sleeve, medium etc., matrix by fastened by screw on locating shaft, between matrix and thin-wall sleeve, adopt interference fit, at matrix and thin-wall sleeve inside, be provided with medium, medium is by under the effect of the downward thrust of matrix top screw, by thin-wall sleeve outer wall rising, workpiece is tightened together with thin-wall sleeve.

Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 partly cuts open structural representation.
Fig. 3 is the plan structure schematic diagram of Fig. 1.
The specific embodiment
As shown in Figures 1 to 3, a kind of numerical control machining center fixture, comprise locating shaft 1, matrix 4 is fastened on locating shaft 1 by screw 3, between matrix 4 and thin-wall sleeve 5, adopt interference fit, at matrix 4 and thin-wall sleeve 5 inside, be provided with medium 9, medium 9 is by under the effect of matrix 4 top screw 8 downward thrusts, by thin-wall sleeve 5 outer wall risings, workpiece 6 is tightened together with thin-wall sleeve 5.
Described locating shaft 1, is provided with locating hole 2 and calibration platform 10.
Described matrix 4 cylindricals adopt step structure, are provided with axial hole and radial hole 7.
Described medium 9, for the medium that pressure transmits, can be elastoplast, hydraulic pressure wet goods.
During the utility model work, the locating hole 2 of locating shaft 1 is rolling center locating hole, and the other end is numerical control machining center dividing head scroll chuck positioning and locking, calibrates the axial and radial accuracy of locating shaft 1 by calibration platform 10.When rotary screw 8 is downwards time, medium 9 make thin-wall sleeve 5 outer wall risings and workpiece 6 fastening, in interference fit, can process workpiece 6.When rotary screw 8 is upwards time, medium 9 and thin-wall sleeve 5 outer walls reset, and thin-wall sleeve 5 in matched in clearance, can freely be changed workpiece 6 with workpiece 6.When needs processing work 6, repeat above-mentioned iterative cycles operation.
The utility model is simple in structure, easy to loading and unloading, calibration is accurate, it is simple and convenient to install, in the small batch production process such as compressor cylinder sleeve, bearing shell lining and special-shaped cylindrical workpieces, on numerical control machining center, once clamping machines, improve machining accuracy, reduce the error producing because of multiple clamping.
