Abstract

The utility model relates to a press-mounting tooling for sliding bearings of valve bodies of variable-displacement plunger pumps, in particular to a tooling for press-mounting sliding bearings into valve bodies of variable-displacement plunger pumps, which belongs to the technical field of variable-displacement plunger pumps. The press-mounting tooling comprises a bottom plate, a press-mounting seat is connected with the top of the bottom plate through a plurality of restoring springs, a lower pressing shaft is fixed at the center of the bottom plate, and a lower pressing shaft positioning boss is arranged on the upper end of the lower pressing shaft. A positioning disk is located right above the press-mounting seat, an upper pressing shaft is slidably mounted in the positioning disk, and an upper pressing shaft positioning boss is arranged on the lower end of the upper pressing shaft. The structure of the press-mounting tooling is simple, compact and reasonable; the press-mounting tooling can press in two sliding bearings of different specifications at the same time, so the assembling efficiency is increased; the workpieces do not need to be turned over, so the verticality of the sliding bearings is guaranteed; the assembling quality is increased; and the press-mounting tooling is easy to operate, and can decrease the labor intensity of workers.

Description

Variable plunger pump valve body sliding bearing press-fitting tool
Technical field
The utility model relates to a kind of Variable plunger pump valve body sliding bearing press-fitting tool, and the valve body that is used for Variable plunger pump specifically press-fits sliding bearing, belongs to the Variable plunger pump technical field.
Background technology
The valve body of Variable plunger pump needs to be pressed into two sliding bearings in portion's process of assembling, be to use simple frock to be pressed into a sliding bearing earlier in the past, and then the upset workpiece carries out press-fiting of another sliding bearing.In process of press in, workpiece will overturn, and operation is more, and frequently changing frock wastes time and energy, and is pressed into the sliding bearing perpendicularity and can not be effectively guaranteed, has influence on the assembly quality of parts.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of Variable plunger pump valve body sliding bearing press-fitting tool is provided, and can be pressed into two sliding bearings simultaneously, workpiece need not upset, perpendicularity is effectively guaranteed, has improved operating efficiency, has improved assembly quality.
The technical scheme that provides according to the utility model, Variable plunger pump valve body sliding bearing press-fitting tool comprises base plate, the base plate upper end press-fits base by a plurality of back-moving springs connections, it is characterized in that: last item under the base plate center fixation, following last item upper end is provided with down the last item positioning boss.Positioning disk is positioned at and press-fits directly over the base, the upper pressure axial that is slidingly installed in the positioning disk, and the upper pressure axial lower end is provided with the upper pressure axial positioning boss.
Further, press-fit the base center and be provided with press mounting hole.
Further, be provided with down the last item jump ring in the following last item positioning boss.
Further, be provided with the upper pressure axial jump ring in the upper pressure axial positioning boss.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, can be pressed into the sliding bearing of two different sizes simultaneously, has improved efficiency of assembling; Workpiece need not upset, has guaranteed the perpendicularity of sliding bearing; Improved assembly quality; Operation has alleviated staff's labour intensity easily.
Description of drawings
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-base plate, 2-back-moving spring, 3-press-fit under base, the 4-under last item, the 5-last item jump ring, 7-upper pressure axial, 8-upper pressure axial jump ring, 9-upper pressure axial positioning boss, 10-positioning disk, 11-press mounting hole, 12-valve body, the last sliding bearing of 13-, 14-properties of journal bearing lubricated, 15-press under last item positioning boss, the 6-.
The specific embodiment
Embodiment during following the utility model is incited somebody to action by reference to the accompanying drawings is further described:
As shown in Figure 1, the utility model mainly comprises base plate 1, and base plate 1 upper end press-fits base 3, last item 4 under base plate 1 center fixation by a plurality of back-moving springs 2 connections, following last item 4 upper ends are provided with down last item positioning boss 5, are provided with down last item jump ring 6 in the following last item positioning boss 5.Following last item positioning boss 5 is used for installing properties of journal bearing lubricated 14, and last item jump ring 6 was at following last item positioning boss 5 chuckings under properties of journal bearing lubricated 14 was passed through.
The utility model also comprises positioning disk 10 and upper pressure axial 7, press-fits positioning valve 12 on the base 3, and positioning disk 10 is installed in valve body 12 upper ends.Positioning disk 10 is positioned at and press-fits directly over the base 3, and upper pressure axial 7 is slidingly installed in the positioning disk 10.Described upper pressure axial 7 lower ends are provided with upper pressure axial positioning boss 9, are provided with upper pressure axial jump ring 8 in the upper pressure axial positioning boss 9.Install sliding bearing 13 on the upper pressure axial positioning boss 9, last sliding bearing 13 tightens at upper pressure axial positioning boss 9 by upper pressure axial jump ring 8.
Describedly press-fit base 3 centers and be provided with press mounting hole 11.
Operation principle of the present utility model is: when mounted, will go up sliding bearing 13, properties of journal bearing lubricated 14 and be installed on upper pressure axial positioning boss 9, the following last item positioning boss 5 by upper pressure axial jump ring 8, following last item jump ring 6 respectively.Press last item 7 downwards by press 15 then, after upper pressure axial 7 arrived spacing position, last sliding bearing 13 was press-fit into place.Upper pressure axial 7 drives workpiece and press-fits base 3 and overcomes back-moving spring 2 and continue to press down, and is press-fit into place up to properties of journal bearing lubricated 14.The utility model is simple in structure, compact, reasonable, can be pressed into the sliding bearing of two different sizes simultaneously, has improved efficiency of assembling; Workpiece need not upset, has guaranteed the perpendicularity of sliding bearing; Improved assembly quality; Operation has alleviated staff's labour intensity easily.
