Description
Technical field
The utility model relates to precision optical machinery manufacture field, the zero external force clamping device used during the copper box class communication workpiece of in particular a kind of fine finishining.
Background technology
When the copper box class communication workpiece 100 shown in manuscript 1, such as with the optical communication heat-dissipating cavity that red metal makes, because the hardness of red metal material self is lower, adopt traditional pressing plate from end face or lateral surface compressing mode, even if remove the allowance of very thin one deck in machining process, the allowance of such as 0.1mm, capital causes some significant points of workpiece 100 to produce larger distortion, such as, by boss (101, 102, 103) flatness of the virtual plane that the boss 104 and in Fig. 2 is formed can produce the deviation of more than 0.3mm after finishing step, these will matching requirements within 0.05mm well beyond this flatness error required by workpiece 100.
Therefore, prior art still haves much room for improvement and develops.
Utility model content
For solving the problems of the technologies described above, the utility model provides zero external force clamping device of a kind of fine finishining copper box class communication workpiece, can ensure that the flatness error of the virtual plane be made up of its multiple boss position is within 0.05mm after fine finishining copper box class communication workpiece, and low processing cost, constant product quality.
The technical solution of the utility model is as follows: zero external force clamping device of a kind of fine finishining copper box class communication workpiece, comprise chuck body, described chuck body is provided with an adaptation and snaps in cavity bottom workpiece, wherein: the oral area of described cavity is provided with a circle chamfering, under the state putting into workpiece, between described chamfering and workpiece, be coated with PUR.
Zero external force clamping device of described fine finishining copper box class communication workpiece, wherein: described PUR smears a circle around workpiece.
Zero external force clamping device of described fine finishining copper box class communication workpiece, wherein: described PUR before smearing for 1625 hot melt rubber sticks are opened up in match.
Zero external force clamping device of described fine finishining copper box class communication workpiece, wherein: the cross section of described chamfering is inclined-plane.
Zero external force clamping device of described fine finishining copper box class communication workpiece, wherein: two right-angle sides of described chamfering are of a size of 2mm × 2mm.
Zero external force clamping device of described fine finishining copper box class communication workpiece, wherein: the bottom surface of described cavity is provided with a fool proof projection.
Zero external force clamping device of a kind of fine finishining provided by the utility model copper box class communication workpiece, the installation way of cavity oral area fixation workpiece is smeared owing to have employed PUR, zero external force clamping is equivalent in finishing passes, compare the installation way of traditional pressing plate from end face or lateral surface compressing, avoid the distortion produced after causing work pieces process because clamping is stressed, meet flatness error technical requirement within 0.05mm of the virtual plane that the multiple boss position of this workpiece is formed, and low processing cost, constant product quality.

Detailed description of the invention
Below with reference to accompanying drawing, described in detail detailed description of the invention of the present utility model and embodiment, described specific embodiment, only in order to explain the utility model, is not intended to limit detailed description of the invention of the present utility model.
As shown in Figure 1, Fig. 1 is the exploded view of the utility model fine finishining clamping device and copper box class communication workpiece, zero external force clamping device of this fine finishining copper box class communication workpiece comprises a chuck body 200, the end face centre of this chuck body 200 is provided with a cavity 210, the large I adaptation of cavity 210 is put into and is treated accurately machined workpiece 100, the mouth rim of this cavity 210 is provided with a circle chamfering 211, for under the state putting into workpiece 100, between chamfering 211 and workpiece 100, smear PUR with fixation workpiece 100 with thermosol gelgun.
For preventing workpiece 100 from oppositely putting into direction cavity 210, preferably, the bottom surface of chuck body 200 cavity 210 is also provided with a fool proof projection 205, to avoid causing processing rear product rejection because workpiece puts back.
Shown in composition graphs 2, Fig. 2 is the installation diagram that the utility model fine finishining clamping device puts into after copper box class communication workpiece, after treating that PUR solidifies, just can carry out finishing step; The slotting cutter of Φ 4 is first adopted to carry out first time fine finishining in finishing passes under the feeding parameter of rotating speed 7000 revs/min, feed speed 500 mm/min and bite 0.15 millimeter, then under the feeding parameter of rotating speed 8500 revs/min, feed speed 850 mm/min and bite 0.15 millimeter, carry out second time fine finishining with Φ 2 slotting cutter, then under the feeding parameter of rotating speed 8500 revs/min, feed speed 600 mm/min and bite 0.1 millimeter, carry out third time fine finishining with Φ 1 slotting cutter; First at the general environmental protection alcohol that the surface sprinkling of PUR is appropriate after processing, more just easily can scrape PUR with small blade, workpiece 100 can be taken out smoothly.
Detected by instrument, the flatness error of the virtual plane that the boss (101,102,103 and 104) on workpiece 100 is formed reaches below 0.03mm, meets the technical requirement of product 0.05mm completely.And traditional solution can't expect way of the present utility model usually, traditional solution generally all can adopt manual synchronizing, or reduce bite and reduction feed speed in fine finishining link, although the quality of product also can reach requirement, but this can improve processing cost all unavoidably greatly, manual operation simultaneously also also exists a lot of parameters, makes the quality of product stable not.
In the preferred embodiment of zero external force clamping device of the utility model fine finishining copper box class communication workpiece, preferably, the PUR being applied to chamfering 211 place is smeared a circle around workpiece 100, to increase the area of PUR fixation workpiece 100 further; Described PUR preferably adopts match to open up 1625 hot melt rubber sticks, to reduce costs.
Fig. 3 is the partial sectional view at chamfering place in Fig. 2, preferably, the cross section of chamfering 211 is inclined-plane, and PUR is smeared in the Delta Region formed between workpiece 100 lateral surface and the chamfering 211 of chuck body 200 cavity oral area thus, can further improve the ability to cure of PUR.
For the workpiece 100 of long 177mm, wide about 127mm, preferably, two right-angle sides of described chamfering 210 are of a size of 2mm × 2mm, both can ensure the bed knife of fine finishining link thus, and can avoid again wastes PUR.
Should be understood that; the foregoing is only preferred embodiment of the present utility model; be not sufficient to limit the technical solution of the utility model; for those of ordinary skills; within spirit of the present utility model and principle; can be increased and decreased according to the above description, replaced, converted or improved, and all these increases and decreases, replacement, conversion or the technical scheme after improving, all should belong to the protection domain of the utility model claims.
