Description
Technical field
The utility model relates to Piston Machining technical field, especially a kind of piston inner diameter localization tool of anti-sticking aluminium skimmings.
Background technique
Piston is generally all positioned using internal diameter to process.Piston inner diameter and localization tool cooperation are tight, and cooperation requires high.
Piston tends to have aluminium skimmings in processing and falls, and flushing tends to have aluminium skimmings residual positioning surface not to the utmost, is influenced, is caused by pad aluminium when piston is placed
Positioning is unstable, influences machining accuracy and production efficiency.
Summary of the invention
In order to solve deficiency in the prior art, the purpose of this utility model is to provide in a kind of piston of anti-sticking aluminium skimmings
Diameter localization tool.
To achieve the above object, the utility model uses following technical scheme:
A kind of piston inner diameter localization tool of anti-sticking aluminium skimmings comprising in the positioning seat of cylindrical shape, the positioning seat
There are multiple positioning surfaces being in contact with piston inner diameter on upper end, be equipped on each positioning surface extended downwardly from positioning surface it is small
The middle part in hole, the positioning seat is equipped with the air channel being recessed inwardly along the external cylindrical surface of positioning seat, and the aperture extends downward into
At air channel, and by air channel each aperture is interconnected, the outside of the air channel passes through sealing element sealing and outside
The middle part of isolation sealing, the positioning seat is equipped with air inlet, and the air inlet is connected to air channel, the air inlet external gas
Pump, gas is passed through in air channel by the air pump by air inlet, and is entered in each aperture by air channel, finally by aperture
It discharges.
The sealing element is brass molding.
The brass is welded on the outside of air channel.
The air inlet is connect by hose with air pump.
The air pump is equipped with ventilation amount detecting device.
The utility model uses above technical scheme, will bore aperture on each positioning contact surface on positioning seat, aperture with
Positioning seat ontology is connected, and gas is connected in parallel connection.Under normal circumstances, positioning surface contacts closely with piston inner diameter, and ventilatory capacity is smaller；When fixed
When having pad aluminium on plane, positioning surface contacts not close with internal diameter, and ventilatory capacity becomes larger.Determined whether to pad by the size of ventilatory capacity
Aluminium, whether jig cooperation is close, keeps positioning more steady, improves machining accuracy and production efficiency.
Detailed description of the invention
The utility model is described in further details below in conjunction with the drawings and specific embodiments:
Fig. 1 is a kind of positive structure schematic of the piston inner diameter localization tool of anti-sticking aluminium skimmings of the utility model；
Fig. 2 is the cross-sectional view of the utility model；
Fig. 3 is the top view of the utility model；
Fig. 4 is the M-M cross-sectional view in Fig. 3；
Fig. 5 is the portion the A enlarged drawing in Fig. 3.
Specific embodiment
As shown in one of attached drawing 1-5, the utility model includes the positioning seat 1 in cylindrical shape, the upper end of the positioning seat 1
There are multiple positioning surfaces 2 being in contact with piston inner diameter in portion, be equipped on each positioning surface 2 extended downwardly from positioning surface 2 it is small
Hole 3, the middle part of the positioning seat 1 are equipped with the air channel 4 being recessed inwardly along the external cylindrical surface of positioning seat 1, and the aperture 3 is to downward
It extends at air channel 4, and by air channel 4 each aperture 3 is interconnected, the outside of the air channel 4 is close by sealing element 5
Envelope is isolated from the outside sealing, and equipped with air inlet 6, the air inlet 6 is connected to air channel 4 at the middle part of the positioning seat 1, it is described into
Gas is passed through in air channel 4 by the external air pump of port 6, the air pump by air inlet 6, and by air channel 4 enter it is each small
In hole 3, finally discharged by aperture 3.
Further, the sealing element 5 is brass molding.
Further, the brass is welded on the outside of air channel 4.
Further, the air inlet 6 is connect by hose with air pump.
Further, the air pump is equipped with ventilation amount detecting device.
The utility model, four internal diameters on positioning seat 1, which position, bores four 1 apertures 3 of φ in plane, and in positioning seat 1
The slot of the circle of outer diameter vehicle one 8 × 2, and outer circle is blocked with brass.Four apertures 3 are made to communicate with one another, channel sealing.Air inlet 6 passes through
After hose coupling connects gas, piston inner diameter and jig positioning injustice or deflection can all cause ventilatory capacity to become larger, and pass through warning reminding
Operating personnel, under normal circumstances, positioning surface 2 contacts closely the utility model with piston inner diameter, and ventilatory capacity is smaller；When positioning surface 2
On when having pad aluminium, positioning surface 2 contacts not close with internal diameter, and ventilatory capacity becomes larger.Determined whether to pad aluminium by the size of ventilatory capacity, be controlled
Whether tool cooperation is close, keeps positioning more steady, improves machining accuracy and production efficiency.
The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention, within the spirit and principle of the utility model,
Any modification, equivalent substitution, improvement and etc. done, should be included within the scope of protection of this utility model.
