Description
Technical field
The utility model relates to the Assembly of the parts in the fiber optic communication field, particularly the accurate press-fit structure of a kind of slip V groove of novel high-axiality.
Background technology
In the production process of fiber products, there are a lot of product needed that the mode of two axial workpieces with interference fit is assembled together, the axiality of the product after assembling is finished simultaneously requires very high.Traditional press-fit tool is to guarantee axiality after two axial workpieces assemblings are finished by the principle that the hole axle cooperates, as shown in Figure 1, part A and part B assemble by the mode of interference fit, require wherein to guarantee that the axle center of part A is consistent with the axle center height of part B.
And the hole axle of above-mentioned employing cooperates the frock of principle, although its processing request to press-fit tool is very high, still can't guarantee to be press-fitted the axiality of product after finishing.And because the versatility of frock is poor, any variation of axial workpiece excircle dimension all needs redesign, processes a whole set of press-fit tool.
Summary of the invention
In order to solve problems of the prior art, the utility model provides a kind of slip V groove of high-axiality accurate press-fit structure.
The utility model provides a kind of slip V groove press-fit structure of high-axiality, comprises a benchmark V-shaped groove, a slide rail, and this slide rail is embedded on the benchmark V-shaped groove, and distributes along the straight line left-right symmetry at this V-shaped groove center line place; It is characterized in that: above-mentioned press-fit structure comprises that further one adjusts cushion block; And above-mentioned adjustment cushion block comprises that a large V groove is adjusted cushion block and a little V groove is adjusted cushion block; Wherein, this large V groove is adjusted cushion block and is embedded on this benchmark V-shaped groove, and distributes along the straight line left-right symmetry at this V-shaped groove center line place; This little V groove is adjusted cushion block and is fixed on this slide rail, and distributes along the straight line left-right symmetry at this V-shaped groove center line place; And this little V groove is adjusted cushion block and is adjusted cushion block direction oriented sliding along slide rail to this large V groove.
Wherein, preferred embodiment is: this large V groove is adjusted cushion block and is used in pairs.
Wherein, preferred embodiment is: this little V groove is adjusted cushion block and is used in pairs.
Pressure rod structure of the present utility model has the following advantages: first, the structure of positioning product is designed to movable large V groove and adjusts cushion block and little V groove adjusting pad block structure on the slide rail, and use in pairs, because paired pad thickness is consistent, so the axle center of two axial workpieces is all dropped on the center line of benchmark V groove; The second, use the structural design of slide rail not only to guarantee centering precision, the feeding, discharge that is highly advantageous to simultaneously operation, and reduce the wearing and tearing of adjusting cushion block; The 3rd, during design, in order to eliminate each part processing, to assemble the error of bringing, the large V groove positioning shaft parts A of having a mind to is adjusted cushion block 30 Thickness Design must be than the large 0.1mm of theoretical value, like this, in the adjustment process of press-fit structure 200, beat the poor H of actual height that table records the summit of axial workpiece A and B by altimeter and (make H＞h) by theory calculating during design, for making the axis coinciding of two axial workpiece A and B, then large V groove cushion block 30 should be ground off thickness
Machine rear assembling and again beat the poor H of table affirmation actual height, make H=h ± 0.005, namely this press-fit structure 200 can guarantee that the theoretical precision of material assembling axiality is 0.005mm.
Description of drawings
Fig. 1 is the schematic diagram that the axial workpiece of existing hole axle cooperation is press-fitted.
Fig. 2 is the stereogram of the accurate press-fit structure of slip V groove of high-axiality of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done further detailed description.
Be illustrated in figure 2 as the accurate press-fit structure 200 of slip V groove of high-axiality of the present utility model.The accurate press-fit structure 200 of the slip V groove of high-axiality of the present utility model comprises slide rail 35, benchmark V-shaped groove 45 and adjusts cushion block 30 3 parts.
Wherein, adjust cushion block 30 and comprise that large V groove is adjusted cushion block 310 and little V groove is adjusted cushion block 320 two parts, large V groove is adjusted cushion block 310 and is embedded on the benchmark V groove 45, is used for loading axial workpiece A.Large V groove is adjusted cushion block 310 along the center line left-right symmetry distribution of benchmark V groove 45.
Wherein, high-precision slide rail 35 is assemblied on the benchmark V groove, and distributes along the center line left-right symmetry of benchmark V groove 45.
Wherein, little V groove is adjusted cushion block 320 and is fixed on the high-precision slide rail 35, is used for loading wherein another axial workpiece B, and little V groove is adjusted cushion block 320 along the center line left-right symmetry distribution of benchmark V groove 45.When product was press-fitted, little V groove was adjusted cushion block 320 and is made oriented sliding along slide rail 35 to this large V groove direction.
Please be simultaneously with reference to Fig. 2, large V groove adjusts cushion block 310 and little V groove is adjusted the structure of cushion block 320 activity of being designed to, and uses in pairs.Because paired large V groove is adjusted cushion block 310 consistency of thickness, paired little V groove is adjusted the consistency of thickness of cushion block 320, so the axle center of two axial workpiece A and B is all dropped on the center line of benchmark V groove.When the axis coinciding of axial workpiece A and B, the poor theoretical value of the apex height of axial workpiece A and B should be h=R-r, and wherein R is the radius of axial workpiece A, and r is the radius of axial workpiece B.
Pressure rod structure of the present utility model has the following advantages: first, the structure of positioning product is designed to movable large V groove and adjusts cushion block and little V groove adjusting pad block structure on the slide rail, and use in pairs, because paired pad thickness is consistent, so the axle center of two axial workpieces is all dropped on the center line of benchmark V groove; The second, use the structural design of slide rail not only to guarantee centering precision, the feeding, discharge that is highly advantageous to simultaneously operation, and reduce the wearing and tearing of adjusting cushion block; The 3rd, during design, in order to eliminate each part processing, to assemble the error of bringing, the large V groove positioning shaft parts A of having a mind to is adjusted cushion block 30 Thickness Design must be than the large 0.1mm of theoretical value, like this, in the adjustment process of press-fit structure 200, beat the poor H of actual height that table records the summit of axial workpiece A and B by altimeter and (make H＞h) by theory calculating during design, for making the axis coinciding of two axial workpiece A and B, then large V groove cushion block 30 should be ground off thickness
Machine rear assembling and again beat the poor H of table affirmation actual height, make H=h ± 0.005, namely this press-fit structure 200 can guarantee that the theoretical precision of material assembling axiality is 0.005mm.
The above is the utility model most preferred embodiment only, is not be used to limiting scope of the present utility model, and all equivalences of doing according to the utility model claim change or modify, and are all the utility model and contain.
