Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Disclosed in the utility model is a kind of moving contact of breaker axle riveting set, as shown in Fig. 2 being the utility model
Preferred embodiment, device includes upper mould 2 and lower mould 3, and lower mould 3 is fixed on a bottom plate 5 by fixed plate 4, and bottom plate 5 is typically logical
Cross and be bolted on riveting machine, riveting machine uses the small cockchafer riveting machines of 3T, to obtain larger riveting pressure.
Specifically, as shown in Fig. 2-8 and 11, the both ends of bottom plate 5 are respectively equipped with a U-shaped hole 51, and bolt is i.e. by being connected to the U
In type hole 51, bottom plate 5 is firmly fixed on riveting machine.Fixed plate 4 is provided with the first spiral shell to be fallen down from above through fixed plate 4
Keyhole 41, bolt are locked on bottom plate 5 after passing through first bolt hole 41.Carry out activity between fixed plate 4 and the lower mould 3 of top
Connection, lower mould 3 can opposing fixed plate 4 move up and down.A plurality of guide pillars and corresponding guide pillar are provided between lower mould 3 and fixed plate 4
Hole, the upper surface of fixed plate 4 is provided with 4 guide pillars 42 in the present embodiment, and the lower surface correspondence position of lower mould 3 sets 4 guide pillar holes 32,
Instantly when mould 3 presses close to fixed plate 4, guide pillar 42 gos deep into guide pillar hole 32 from below, and guide pillar 42 is with guide pillar hole 32 to fixed plate 4 and lower mould
3 position-limiting actions, it is accurately positioned between both realizations to mutual.Certainly, guide pillar 42 can also be mounted at fixed plate 4
On, now just need to set a plurality of lower guide pillar holes 43 in fixed plate 4, as shown in Figure 7.Guide pillar hole 43 can be cylindrical hole,
Then guide pillar 42 is cylinder, and guide pillar hole 43 is entered in direct grafting.Guide pillar 42 is also designed to above and below the cylinder that two sections of diameters do not wait
The integrative-structure formed is superimposed, wherein the diameter positioned at hypomere is greater than the diameter of epimere, as shown in figure 11, corresponding guide pillar hole
