Description
Technical field
This utility model relates to a kind of adhering device, is specifically related to a kind of ultra-thin ring plate precision Special device for bonding.
Background technology
In photoelectric communication field, the Precision Machining of some vital parts to use the abrasive cut-off wheel of a kind of 3A1 type, as shown in Figure 1.This abrasive wheel is made up of ultra-thin ring plate 3 and matrix 1 two parts, and both are connected one entirety of formation by bonding way (i.e. glue-line 2), and wherein ultra-thin ring plate 3 overhangs out the width of matrix 1 at 3-5mm.Ultra-thin ring plate 3 is sintered type diamond abrasive working lining, acts primarily as mill and cuts effect, and ring plate ring width is between 8-10mm, and thickness is at below 0.15mm, extremely thin, poor rigidity；Matrix 1 is aluminium, relatively thick (about 4mm), acts primarily as supporting role, strengthens abrasive cut-off wheel rigidity, can make supporting with machine tool chief axis simultaneously, conveniently operate with.
This emery wheel requires that the end face run-out of abrasive material working lining relative matrix hole footpath axis is within 0.02mm.The making of adhered 3A1 abrasive wheel is had following technology difficulty by this: abrasive material working lining is ultra-thin ring plate, and any unbalance stress very easily deforms；(these factors are the persistent ailments of technique for sticking to there is uncontrollable factor in bonding solidification process, current industry level can not solve) just can affect the deformation of ultra-thin ring plate shape abrasive material, as bonding agent mixes uneven with firming agent, rubber thickness asymmetry, glue-line consistency is inconsistent, and then when causing colloid cure shrinkage, glue-line contraction state everywhere is inconsistent, bonding colloid cure shrinkage, ultra-thin ring plate abrasive material is had by it certain pulls effect, due to the contraction of bonding colloid uneven, therefore bonding agent to abrasive material to pull active force also uneven, and ring plate abrasive material is extremely weak, rigidity is very poor, so bonding glue shrinkage is easy to cause ultra-thin ring plate abrasive material to deform；Effective means are not had to correct the deformation of ultra-thin ring plate after bonding solidification.As long as ultra-thin ring plate deforms, the jitter values of emery wheel is very easily overproof, and therefore an above-mentioned difficult problem constrains the batch production of this abrasive wheel.
Utility model content
In order to overcome the defect of prior art, this utility model provides a kind of ultra-thin ring plate precision Special device for bonding.
Based on above-mentioned purpose, this utility model adopts the following technical scheme that:
Ultra-thin ring plate precision Special device for bonding, including vacuum cup and jacking mechanism, described vacuum cup is made up of base, end cap, swivel joint, trachea and valve: end cap covers on base, and between base and end cap, form a cavity, the center of base is provided with a tapped through hole, threadeding with tapped through hole in one end of swivel joint, the other end connects trachea, the other end connecting valve of trachea；Described jacking mechanism is made up of push rod, meter pressing spring, linear bearing, cored screw and driving swivel nut: push rod is ┣ font, the right-hand member of push rod sheathed linear bearing, cored screw and driving swivel nut successively from the inside to the outside, the length of cored screw is more than driving the length of swivel nut so that driving swivel nut can rotate on cored screw and move back and forth；Described meter pressing spring is sheathed on push rod, and counts one end and the push rod apical grafting of pressing spring, the other end and driving swivel nut apical grafting.
The center of described end cap is provided with the locating core of a projection, and the end cap outside locating core is provided with excessive glue groove, and the longitudinal center line of excessive glue groove and locating core coincides；The uniform some micropores of circumferencial direction of the excessive glue groove in edge, end cap place overflow outside glue groove.
Base and end cap are connected by screw is fixing, be provided with tapped through hole, threaded with swivel joint in the middle of base, swivel joint opposite side can trachea soon, trachea is provided with valve, and this valve has two functions: (1) gas-tpe fitting, (2) air inlet switch.
End cap is provided with cavity and precision surface plate, and both pass through micropore UNICOM, and micropore is uniformly distributed on concentric circular, and end cap is provided with excessive glue groove and locating core according to the structure of 3A1.Before bonding, ultra-thin ring plate is adsorbed onto on the accurate table top of end cap, after matrix B topcoating glue, is installed on locating core by its endoporus, then hold out against by jacking mechanism pressure.After glue-line compacting (matrix A face and the laminating of vacuum cup table top) and fully infiltrating with ultra-thin ring plate, unclamp jacking mechanism and lay down vacuum, take off 3A1 emery wheel, remove the excessive glue of matrix and ring plate intersection, then vacuum cup and jacking mechanism it are reinstalled again, separating with vacuum pump after extracting vacuum, this device moves entirely in solidification case, makes curable adhesive layer.Remove vacuum after having solidified, unclamp jacking mechanism, take off 3A1 emery wheel, complete whole technique for sticking.So in bonding, pressurization, solidify three phases, ultra-thin ring plate side positions absorption with the precision surface plate of vacuum cup all the time, the precision surface plate of vacuum cup and ultra-thin ring plate became one, ultra-thin ring plate is formed axial support, overcoming bonding with pressure process, ultra-thin ring plate side pressurized inequality causes deformation；There is an absorption affinity ultra-thin ring plate side by vacuum cup simultaneously, can effectively resist the colloid solidification pull (ultra-thin ring plate side tension) to ring plate and act on, and then avoid ultra-thin ring plate to be deformed in the curing process.
Jacking mechanism is made up of push rod, meter pressing spring, linear bearing, driving swivel nut and cored screw.Cored screw is fixed, swivel nut is driven to be connected with cored screw screw thread pair, rotate and drive swivel nut, it can move along screw axis, linear bearing is fixed on inside cored screw, and meter pressing spring is enclosed within push rod axle, and push rod axle penetrates in linear axis bearing bore and can be free to move axially, reciprocating rotary bearing play the guiding role, and meter pressing spring is limited at push rod head and drives between swivel nut.
The mechanism of jacking mechanism is to rotate to drive swivel nut to move forward, and drives swivel nut to meter pressing spring pressure, and spring promotes push rod reach to withstand grinding wheel base body；Unclamp jacking mechanism then opposite direction and rotate driving swivel nut.
When ensureing adhesive strength, ultra-thin ring plate for different-thickness, vacuum can be passed through or the micropore gross area regulates the sucker absorption affinity to ring plate, the contractility that colloid solidifies is regulated also by increasing filler in adhesive, and then regulate colloid ring plate pullled power, thus keeping ultra-thin ring plate stress balance.
This utility model is that ultra-thin ring plate provides location absorption platform and axially supporting, and auxiliary strengthens ultra-thin ring plate rigidity, improves its opposing axial compression and glue-line pulls the ability of (ultra-thin ring plate side tension).When solving to be made 3A1 emery wheel by ultra-thin ring plate shape abrasive material, the problem that ultra-thin ring plate is easily generated deformation in bonding solidification process, it is ensured that the end of bonding rear abrasive material jumps precision, provide technical support and equipment condition for emery wheel batch production.
