Description
Technical field
The utility model relates to a kind of center positioning device of CNC milling machine, is specifically related to a kind of wheel hub CNC milling machine centralized positioning expansion sleeve.
Background technology
Wheel hub carries out adding man-hour at milling machine, in order to process accurately, wheel hub is needed to carry out centralized positioning, normally carry out coordinating being located with the center mounting hole of wheel hub by centralized positioning axle, but position like this, just need the size of centralized positioning axle and hub installing hole matching degree high, installing hole is much just needs great axle core, and must accomplish that product center installing hole just can play positioning action than the large 0.1 ± 0.05mm of locating shaft, the oversize workman of locating shaft installs difficulty, locating shaft its effect less than location undersized, because its machining accuracy is high, so working (machining) efficiency is low, processing cost is high.
Utility model content
The utility model is intended to provide one to facilitate workman to install the good wheel hub CNC milling machine centralized positioning expansion sleeve with locating effect.
Wheel hub CNC milling machine centralized positioning expansion sleeve in this programme, comprise be fixed on pedestal on milling machine and in pedestal by the movable axis of milling machine Air Valve Control, the stiff end of movable axis connects the output of air valve, the extended pedestal of free end of movable axis, also comprise expansion sleeve, described expansion sleeve to be detachably fixed on pedestal and to be enclosed within outside movable axis, movable axis vertical direction in pedestal and expansion sleeve moves, described movable axis is with tapering, movable axis broadens admittedly gradually from its centre to its free end, the internal diameter of expansion sleeve is narrowed to middle part gradually by top, the internal diameter of expansion sleeve and the size of movable axis match.
Compared with prior art, the utility model has the advantages that: movable axis passes through Air Valve Control, make its upper surface concordant with the upper surface of expansion sleeve, then be inserted on expansion sleeve by the central hole of wheel hub, Air Valve Control movable axis is return, because movable axis broadens admittedly gradually from its centre to its free end, the internal diameter of expansion sleeve is narrowed to middle part gradually by top, movable axis is by expansion sleeve distending after returning, and then by the centre bore swelling of wheel hub, locating effect is better.Compared with prior art, accurately need not process center locating shaft, reduce cost, and also improve operating efficiency.
Further, the bottom end of described expansion sleeve is outward extended with boss, and boss has through hole, and described expansion sleeve is fixed on pedestal by the screw in through hole.Expansion sleeve is fixedly connected on pedestal by screw, can prevent wheel hub from driving locating shaft radial rotating man-hour adding like this, affect machining accuracy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model wheel hub CNC milling machine centralized positioning expansion sleeve embodiment;
Fig. 2 is the schematic diagram after hub centre is located by the utility model wheel hub CNC milling machine centralized positioning expansion sleeve.
In figure, 1 is pedestal, and 2 is movable axis, and 3 is screw, and 4 is wheel hub, and 5 is expansion sleeve.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
According to Fig. 1, shown in Fig. 2, the utility model provides a kind of wheel hub CNC milling machine centralized positioning expansion sleeve, comprise the pedestal 1 on milling machine, there is through hole at pedestal 1 center, movable axis 2 is through this through hole, the stiff end of movable axis 2 gives power (not shown) by the air valve of milling machine, expansion sleeve 5 low side is outward extended with the boss of annular, boss there is through hole, screw 3 makes it be fixed on pedestal 1 through the through hole on expansion sleeve 5 boss, because the processing mode of milling machine is for rotating processing, if expansion sleeve 5 is not fixed, can rotation be there is in expansion sleeve 5, affect the machining accuracy of milling machine.Expansion sleeve 5 is enclosed within outside movable axis 2, and movable axis 2 can pass expansion sleeve 5 and its free end can stretch out expansion sleeve 5.Movable axis 2 one end is with tapering, namely movable axis 2 broadens admittedly gradually from its centre to its free end, the internal diameter of corresponding expansion sleeve 5 is narrowed to middle part gradually by top, the size of the internal diameter of expansion sleeve 5 and movable axis 2 is matched, after above-mentioned design, when the end face of movable axis 2 is concordant with the end of expansion sleeve 5, movable axis 2 also can not by expansion sleeve 5 distending, the outer wall of expansion sleeve 5 is still vertical, then the centre bore of wheel hub 4 is installed on expansion sleeve 5, now air valve pulls movable axis 2, movable axis 2 continues to move in expansion sleeve 5, such movable axis 2 just can by expansion sleeve 5 distending, can by the central shaft swelling of wheel hub 4, complete location, , when air valve outwards promotes movable axis 2, expansion sleeve 5 recovers deformation, wheel hub 4 can be taken out.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
Claims (2)
1. wheel hub CNC milling machine centralized positioning expansion sleeve, comprise be fixed on pedestal on milling machine and in pedestal by the movable axis of milling machine Air Valve Control, the stiff end of movable axis connects the output of air valve, the extended pedestal of free end of movable axis, it is characterized in that: also comprise expansion sleeve, described expansion sleeve to be detachably fixed on pedestal and to be enclosed within outside movable axis, movable axis vertical direction in pedestal and expansion sleeve moves, described movable axis is with tapering, movable axis broadens admittedly gradually from its centre to its free end, the internal diameter of expansion sleeve is narrowed to middle part gradually by top, the internal diameter of expansion sleeve and the size of movable axis match.
