Description
Technical field
The utility model is related to the stationary fixture of material processing, more particularly to a kind of fixture of vacuum adsorption.
Background technology
The fixed form of traditional machining is generally vice clamping or pressing plate attachment screw is clamped, this two kinds
The speed that installation way has clamping and unloading clip is slow, is easy to leave on the surface of processed product in the case of firmly irregular
The vestige of clamping, the later stage needs to handle these vestiges.Become in addition, traditional method of clamping also easily presss from both sides converted products
Shape.
With the extensive use of precision sheet class formation part in electronics industry, traditional method of clamping can not meet precision
The requirement of processing, vacuum adsorption fixture is gradually generalized in the processing of precision sheet.Vacuum adsorption fixture is various non-in clamping
In the machining of the thin plate class formation part such as magnetic metal and all kinds of insulating materials, there is its unique advantage.Vacuum suction is pressed from both sides
Tool is fast with clamping unloading clip speed compared to traditional vice or the method for clamping of pressing plate attachment screw, and production efficiency is high, use
Reliable and stable the features such as, especially effect is especially notable in terms of deformation in overcoming precision sheet class formation part process.
The structure of traditional vacuum adsorption fixture is typically that a cavity is milled out in the centre of adsorption plate, passes through outer connector
Connect with flexible pipe with vavuum pump, then get out on the surface of adsorption plate through hole that several connect with cavity as adsorption hole, its work
As principle be by pumping the air in cavity, sheet workpiece is developed the through-hole surfaces in adsorption plate, play absorption it is fixed and
Smoothing is acted on.The vacuum adsorption fixture of the structure is relatively simple for structure, makes easy, but simultaneously there is also following shortcoming and not
Foot：First, each fixture can be only applied to the thin plate of same specification, poor universality；The making of other this fixture takes
Long, cost of manufacture is high（Calculated by one piece of adsorption plate, 2000 absorption through holes, only CNC drillings are accomplished by time-consuming 30 to 36 hours）.
Secondly, in order to prevent gas leakage, the surrounding being required for each time during clamping in sheet workpiece is sticked adhesive tape and sealed, and adhesive tape can only
Disposable, viscosity will be lost by meeting surface after water or oil, therefore consumption is needed during this vacuum adsorption fixture ongoing operations
Substantial amounts of adhesive tape.Furthermore, the use of adhesive tape is easy to the table in sheet workpiece after not only increasing production cost, and use
Face leaves cull, and the later stage removes pretty troublesome.Finally, due to which the hollow structure of adsorption plate, the later stage is easy to occur in the middle of adsorption plate
Depressed phenomenon, influences the precision of processing.
The content of the invention
The purpose of this utility model is to provide that a kind of versatility is good, it is simple to make, without rubber belt sealing and structural strength is high
Vacuum adsorption fixture.
To achieve these goals, a kind of air flue type vacuum adsorption fixture that the utility model is provided, including base and suction
Attached plate, adsorption plate is arranged on base, wherein, the surface of adsorption plate is provided with the air flue of a plurality of intersection, and air flue is from adsorption plate
Surface to the groove of adsorption plate inner recess, the gas port of adsorption plate is provided through on the crosspoint of air flue；In air flue
Sealing strip optionally is provided with, the depth of air flue is less than sealing strip diameter, and gas port is trapped among an annular region by sealing strip
It is interior；Vacuum interface is provided with base, vacuum interface is connected with gas port.
As seen from the above technical solution, the setting of air flue can not only play a part of air guide and absorption, and in air flue
Sealing strip can be set, can select corresponding air flue that sealing strip is set according to the shapes and sizes of sheet workpiece to be processed,
Versatility is good；Air flue is groove structure, it is only necessary to milled out on the surface of adsorption plate the grooves of respective shapes just can, relative to brill
Hole, makes simple；Sealed using sealing strip, without adhesive tape；It is evacuated using gas port, it is not necessary in being set in the middle of adsorption plate
Empty cavity, the structural strength of adsorption plate is high, is unlikely to deform.
Further scheme is that air flue includes transverse air channel and longitudinal gas channel, and gas port is located at transverse air channel and longitudinal gas
On the crosspoint in road, sealing strip optionally is provided with transverse air channel and longitudinal gas channel；Transverse air channel and longitudinal gas channel are being inhaled
The surface of attached plate marks off multiple small boss with flat surface.
It can be seen that, transverse air channel and longitudinal gas channel it is simple in construction, make simple, the setting of sealing strip is also very simple, small convex
The surfacing of platform, prevents from inhaling the deformation of sheet workpiece attached to it.
Further scheme is, air flue also includes annular air channel, and annular air channel is arranged on transverse air channel and longitudinal gas channel
Periphery, transverse air channel, longitudinal gas channel and annular air channel are interconnected.
It can be seen that, sealing strip can be set in annular air channel, large-sized sheet workpiece is processed.
Further scheme is that transverse air channel, longitudinal gas channel are identical with the cross sectional shape of annular air channel.
It can be seen that, all air passage structures are identical, and the processing of air flue is simpler.
Further scheme is that gas port is provided with two, and first that two gas ports of connection are provided with base is led to
The second channel of connection first passage and vacuum interface is additionally provided with road, base.
As can be seen here, when two gas ports of setting prevent one of air guide hole plug, another gas port can also rise
Effect；Set first passage and second channel relative to the middle cavity for setting large area on base, add bulk strength, adsorb
Plate is not easy the phenomenon for intermediate recess occur.
Further scheme is that sealing strip is expansion type silica gel strip, and small 0.2 millimeter of air flue depth ratio sealing strip diameter is extremely
0.4 millimeter.
It can be seen that, this silica gel strip has soft texture, and resilience is good, and oil resistant is water-fast, the advantages of reusable.
Further scheme is, the small 0.2mm of air flue depth ratio sealing strip diameter.The bottom of air flue is set to circular arc.
It can be seen that, the shape of air flue bottom matches with the shape of sealing strip, improves the sealing of sealing strip.
