Description
Technical field
The utility model relates to Hydraulic Elements valve body aperture machinery processing apparatus, and particularly relating to floats finish reams aperture apparatus.
Background technology
Hydraulic Elements performance quality, except structural design, the fine finishining in valve body aperture directly influences the Hydraulic Elements serviceability.At present, the fine finishining in valve body aperture has three kinds of forms substantially, and a kind of is the rigidity fraising, be cutter rigid attachment swivel feeding, workpiece is rigidly fixed in and carries out fine finishining on the platen, and its apparatus structure is simple, influenced but process machine tool self precision, machining accuracy is lower; Second kind is the mode in honing aperture, and promptly workpiece is fixed on the honing machine workbench and rotates, and the honing head rotation also moves back and forth.This kind fine finishining mode has higher dimensional accuracy and geometric accuracy than first kind, but less economical, and changing bistrique and adjusting abrading block needs the long period, and efficient is lower, generally is applicable to produce in enormous quantities.The third is the reciprocating mode of spin finishing rod manually, this kind mode, and manual skill requires high, otherwise is difficult to guarantee geometric accuracy and dimensional accuracy, and grinding efficiency is very low, can only be used for single and mini-batch production production.The Hydraulic Elements valve opening processing of above-mentioned three kinds of method centerings small lot batch manufacture is all not very good.
The utility model content
The technical problems to be solved in the utility model provides a kind of economic, practical, efficient dimensional accuracy that can satisfy Hydraulic Elements again, is fit to the unsteady aperture apparatus that finish reams that small batch is produced the processing of Hydraulic Elements valve opening.
The technical scheme that adopts is:
Float and finish ream aperture apparatus, comprise base plate, pressure strip, locating piece, adjustment plate, column and pulley mechanism.Be laid with the spring that can make workpiece float and feel relieved in the described base plate, its spring upper end is replaced and is being adjusted the plate bottom surface, and locating piece is fixed on to be adjusted above the plate.The fixedly connected base plate of described column one end, the other end is fastening by nut and pressure strip.Described pulley mechanism comprises first pulley, second pulley, the 3rd pulley and the 4th pulley, first pulley and the 3rd pulley side are to the corresponding base plate of fixedlying connected, and be connected with the machine tool guideway both sides respectively, again with the set spring pretension location of the 3rd pulley, second pulley is fixedlyed connected base plate with the 4th pulley, and be connected respectively with above lathe two guide rails, can make vertically back and forth walking of device.Adjust on the plate and adorn workpiece, and make the workpiece axial location by locating piece, promote the hole introducing cutter that column is processed workpiece, compress in advance by pressure strip above the workpiece, get final product the fine finishining aperture, constituting floats finish reams aperture apparatus.
The beneficial effect that the utility model is obtained is:
In concrete operations, the walking light and flexible, workpiece can be with weight change, and regulating spring is realized universal unsteady, self-centering.At the workpiece of different apertures and weight, can reach desirable processing effect as long as change different spring and cutters.This device is practical simple and direct, and it is fast to change cutter and spring, and the efficient height is not subjected to the influence of machine tool accuracy to reach specification requirement fully, is fit to the processing of Hydraulic Elements valve opening small batch.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the K of Fig. 1 is to view.
The specific embodiment
Float and finish ream aperture apparatus, comprise base plate 4, pressure strip 1, locating piece 3, column 11 and pulley mechanism.Be laid with the spring 9 that can make workpiece float and feel relieved in the described base plate 4, its spring 9 upper ends are replaced and are being adjusted plate 10 bottom surfaces, and locating piece 3 is fixed on to be adjusted above the plate 10.The fixedly connected base plate 4 of described column 11 1 ends, the other end is fastening by nut and pressure strip 1.Described pulley mechanism comprises first pulley 5, second pulley 6, the 3rd pulley 7 and the 4th pulley 8, first pulley 5 and the corresponding base plate 4 of fixedlying connected of the 3rd pulley 7 side direction, and be connected with machine tool guideway 12 both sides respectively, locate with the 3rd pulley 7 set spring 13 pretensions again, second pulley 6 is fixedlyed connected base plate 4 with the 4th pulley 8, and be connected respectively with above lathe two guide rails 12, can make vertically back and forth walking of device.Adorn workpiece 2 on the adjustment plate 10, and make workpiece 2 axial location by locating piece 3, promote the hole introducing cutter that column 11 is processed workpiece 2, compress in advance by pressure strip 1 above the workpiece 2, get final product the fine finishining aperture, formation is floated and is finish reamed aperture apparatus.
Operation principle
Workpiece 2 is contained in to be adjusted on the plate 10, with the workpiece axial location, promotes the hole introducing cutter that column 11 is processed workpiece 2 with locating piece 3, and after pilot centering was adjusted, pretension pressure strip 1 can the fine finishining aperture.At this moment, the workpiece 2 of processing can along with about the cutter, about follow the cutter self-centering.The workpiece self-centering mainly is the selection of spring 9, can adjust according to the weight of workpiece 2 and the position of machining hole.It is the deflection of the number of packages * workpiece of rigidity * spring of the weight=spring of workpiece spring when being pressed into.The adjustment of centre-height can be carried out the selection of spring free height according to different workpiece centre height, also can change adjustment plate 10 and be adjusted.Process is not subjected to the gravity of workpiece, and the influence of cutter radial power, axial thrust load processes accessible required precision.Install its circularity of accurately machined aperture with this and can reach 0.001-0.003mm, cylindricity can reach 0.003-0.005mm, improves work efficiency 3-5 doubly than honing bores.
