Description
Technical field
The present invention relates to Ultraprecision Machining field, specifically a kind of ultrasonic wave milling machine processing hasThe processing method of the fan-shaped workpieces of lightening hole plane.
Background technology
The mode that tradition processing has the fan-shaped workpieces of lightening hole plane is: downward when sphere, processWhen workpiece bottom, be chosen in side clamping, soared with clamp base in workpiece bottom, afterwardsAdopt the mode of getting ready on workpiece bottom, determine that bottom surface is horizontal. Due to needs againGet ready benchmark, operation is loaded down with trivial details, and measures while generation again, easily produces error, can not ensure completelyAbswolute level after the upset of bottom surface.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of ultrasonic wave milling machine and add instrumentThere is the processing method of the fan-shaped workpieces of lightening hole plane, realize two circular arcs up and down of fan-shaped speculumThe processing of side, two angle sides and baseplane needs, and meanwhile, meets requirement on machining accuracy,Guarantee the precision of face type and size.
The principle of the invention is as follows:
The problem that first will solve is the processing of baseplane, because upper surface is a spherical, and can notAs datum plane, processing must be carried out benchmark transmission by fixture when the bottom surface.
The problem of second solution is to want the disposable processing that completes four sides, and holding workpiece can notInterfere, can only clamp by the bottom surface that has a large amount of lightening holes, will ensure after clamping simultaneouslyThe depth of parallelism of bottom surface, so that the behavior tolerance of processing side can reach requirement.
Technical solution of the present invention is as follows:
The processing of ultrasonic wave milling machine has a processing method for the fan-shaped workpieces of lightening hole plane, its spyPoint is, comprises that fan-shaped base, two boss cushion blocks, two boss fixture blocks and polylith are threadedThe module in hole, the size of the size of this module and described lightening hole is suitable; The method comprise asLower step:
Step 1, the baseplane of fan-shaped workpieces to be processed is processed, specific as follows:
1., fan-shaped workpieces is lain on fan-shaped base, two boss cushion blocks are respectively with fan-shaped baseTwo straight flanges are fixed, on boss fixture block fixing lug boss cushion block;
2., on boss fixture block, offer glue groove, and pour into bonded adhesives, make the side of fan-shaped workpieces and protrudingPlatform fixture block is fixed, and the height of boss fixture block is higher than the height of fan-shaped workpieces;
3. with ultrasonic wave milling machine, the boss fixture block on both sides is carried out to plain milling, make workpiece bottom and boss fixture blockUpper surface parallel;
4. the workpiece of boss fixture block and adhesion is unloaded from boss cushion block;
5. with ultrasonic wave milling machine, the upper surface of boss cushion block is carried out to plain milling, make the upper surface of boss cushion blockParallel with the upper surface of fan-shaped base;
6. adhesion there is is the boss fixture block upset of workpiece to fix with the boss cushion block of being crossed plane by milling afterwards, makeWorkpiece bottom upward;
Step 2, four of fan-shaped workpieces to be processed sides are processed, specific as follows:
1. module is put into respectively after described lightening hole, and bonding agent is poured into the screw thread of each moduleKong Zhong, fixes module and workpiece to be processed;
2. on fan-shaped base with the corresponding position of module screwed hole that is connected fan-shaped workpieces, stamp phaseSame screwed hole, is then placed on fan-shaped workpieces on fan-shaped base, and aims at screwed hole, uses screwAfter fan-shaped base and fan-shaped workpieces is fixing, four of fan-shaped workpieces sides are processed.
Compared with prior art, the invention has the beneficial effects as follows:
(1) realize two circular arc sides up and down of fan-shaped speculum, two angle sides and the end flatThe processing of face needs.
(2) utilize boss to lean on piece and boss cushion block to carry out benchmark transmission, can increase greatly processingEfficiency, save the time to benchmark again got ready.
(3) owing to being benchmark transmission, can reduce and measure again the error producing, traditional approach is notCan ensure the rear abswolute level of bottom surface upset completely.
(4) meet requirement on machining accuracy, guarantee the precision of face type and size.
