The specific embodiment
The below describes embodiment of the present utility model in detail, and the example of described embodiment is shown in the drawings, and wherein identical or similar label represents identical or similar element or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment that is described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
In description of the present utility model, it will be appreciated that, term " " center "; " vertically "; " laterally "; " front "; " afterwards "; " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", orientation or the position relationship of indications such as " outward " are based on orientation shown in the drawings or position relationship, only be for convenience of description the utility model and simplified characterization, rather than device or the element of indication or hint indication must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model.
The utility model provides a kind of monoblock type trunnion shaft and leaf spring pressing platform, as shown in Figure 1-Figure 3.Comprising: agent structure 1, main body supporting structure for whole pressing platform, it is the supporter of realizing that trunnion shaft parts, plate spring component attach together, comprise supporting surface and bracing frame, described supporting surface is comprised of two longerons and two crossbeams at least, and this bracing frame connects supporting surface and is used for pressing platform steadily is positioned over ground; Be provided with sliding panel 6 at these longeron two ends;
Four transfer mechanisms 2, lay respectively at the two ends of described two longerons, be slidingly connected with described longeron by described sliding panel 6, realize that cylinder advances, retreats, to adapt to different size trunnion shaft product, transfer mechanism 2 also is the supporting construction in the countercylinder course of work simultaneously;
Four cylinders 3 lay respectively on described four transfer mechanisms 2, are used for leaf spring is press-fited the mechanism that the process both sides leaf spring depth of parallelism guarantees; Carry out the input of power by tracheae, joint countercylinder, and use travel switch control cylinder to move forward and backward;
Four limiting components 4 lay respectively at described sliding panel 6 near an end at longeron center, and it is spacing to realize that cylinder 3 carries out the leaf spring outside in the pressure process of top, guarantee that simultaneously both sides, leaf spring front and back are consistent.Limiting component 4 can have multiple way of realization, for example shown in Fig. 1, different distance arranges limit pin hole 5 on the corresponding sliding panel 6 of transfer mechanism 2, at corresponding limit pin hole 5 spacer pin 4 is set, it is spacing to realize that cylinder 3 carries out the leaf spring outside in the pressure process of top, guarantees simultaneously the consistent structure in leaf spring both sides, front and back.Certainly limit pin hole 5 also can not be arranged on the sliding panel 6, and is arranged on sliding panel 6 agent structure 1 outward.
