Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 2 is the dress pressure device structural representation of gear pump floating buss sub-assembly.As seen from the figure, it includes cope match-plate pattern 1 and lower bolster 2, and cope match-plate pattern 1, lower bolster 2 are installed the mould bases of guide pillar 3 and guide pin bushing 4 composition respectively.Cope match-plate pattern 1 is provided with two pressure heads 6 matched with floating buss 5 liang of pitchs of holes, and Step Shaft is made in the front end of pressure head 6, external diameter foremost with press the endoporus of lining 7 to match, length is the half of lining 7 length; The external diameter of secondary front end and the endoporus of floating buss 5 match, lower bolster 2 is provided with two location mandrils 8 relative with pressure head 6, Step Shaft is also made in the front end of location mandril 8, external diameter foremost with press the endoporus of lining 7 to match, length is slightly longer than lining 7 length; The external diameter of secondary front end and the endoporus of floating buss 5 match.Lower bolster 2 is stretched out in the rear end of location mandril 8, and is connected with elastic device, and lower bolster 2 is scalable relatively for location mandril 8.Described elastic device is fixed with the connecting plate 10 parallel with lower bolster 2 through bolt 9 is unsettled below lower bolster 2, connecting plate 10 is provided with the through hole 11 that location mandril 8 passes, location mandril 8 below lower bolster 2 is shaped with convex shoulder 12, location mandril 8 between convex shoulder 12 and connecting plate 10 overlaps and has Compress Spring 13, location mandril 8 relies on Compress Spring 13 jack-up.Guide pillar 3 is provided with the locating piece 13 of axial adjustment, the degree of depth in floating buss 5 is pressed into control pressure head 6, described axial adjustment is shaped with external screw thread 15 on guide pillar 3, locating piece 14 is shaped with the screw 16 matched with external screw thread 15, and by being spun on locating piece 14 on guide pillar external screw thread 15 and the axial location location of locking nut 17 pairs of locating pieces 14 on guide pillar 3.
During use, put on location mandril 8 by needing the floating buss 5 press-fited, make planes overlapping on floating buss 5 lower surface and lower bolster 2, put in location mandril 8 upper end again and need the lining 7 that press-fits, press mounting machine tool slide block move down in process drive cope match-plate pattern 1 to make successively guide pillar 3 contacts with guide pin bushing 4, pressure head 6 promotes that location mandril 8 moves down, Compress Spring 13 forced compression, pressure head 6 end face is with floating buss 5 end contact and after locating piece 13 end face pressing down, be fixed on guide pillar 3 overlaps with guide pin bushing 4 end face as shown in Figure 3.Lathe slide block stops descending, and move up, the floating buss sub-assembly press-fited ejects as shown in Figure 4 by location mandril 8 under the effect of Compress Spring 13, takes off floating buss sub-assembly, and the work of whole dress pressure completes.
