Fig. 4 is an assembly work view of the present invention.
Number in the figure: stage clip, 4 bearings, 5 shaft block rings, the 6 guiding vertex of a cones, 7 are marked closely on screw, 8 addendum cone springs, 9 main shafts, 10 pallet dollies, 11 straight lengths, 12 bearing inner races, 13 fixedly pressure head, 14 seaming chucks, 15 main cone axles, 16 centring rings in 1 lower support pressure head, 2 guiding pressure heads, 21 Rotary-tables, 3 pipes.
Below by the specific embodiment, the invention will be further described in conjunction with the accompanying drawings.
The specific embodiment
Referring to Fig. 1, setting can be with the up lower support pressure head 1 of following oil cylinder axle crawl in the two dynamic compressor system, lower support pressure head 1 is a sleeve structure, guiding pressure head 2 is coaxial to be arranged in the pipe of lower support pressure head 1, the tail end face of guiding pressure head 2 is supported by stage clip in the pipe of lower support pressure head 13, and guiding pressure head 2 can endwisely slip in the pipe of lower support pressure head 1; The epimere of guiding pressure head 2 is that upper base is big, the little Rotary-table 21 of going to the bottom, the straight length 11 of the ccontaining described Rotary-table 21 of epimere Guan Weike of lower support pressure head 1, the guiding pressure head 2 that is supported by stage clip in the pipe 3 protrudes out on lower support pressure head 1 top end face with its epimere Rotary-table 21.
Referring to Fig. 2, bearing 4 that is assembled and shaft block ring 5 with shaft block ring 5 down, bearing 4 is sleeved on the periphery of Rotary-table 21 in last order.
In concrete the enforcement, center of top at guiding pressure head 2 has the guiding vertex of a cone 6, can be with the guiding vertex of a cone 6 and the 2 split settings of guiding pressure head, guiding pressure head 2 is set to body, the guiding vertex of a cone 6 is the body of rod in the body that is arranged on guiding pressure head 2, in the body of guiding pressure head 2 addendum cone spring 8 is set, the body afterbody of guiding pressure head 2 is by marking closely screw 7 back covers, and the body of rod resiliency supported of the guiding vertex of a cone 6 is on addendum cone spring 8.
Referring to Fig. 3, lower support pressure head 1 is positioned down on the oil cylinder axle, middle flexible when having guaranteed that by stage clip 3 support guide pressure heads 2 in managing guiding pressure head 2 is stressed, in the guiding pressure head 2 again by the addendum cone spring 8 and the holding screw 7 support guide vertex of a cones 6, the center of the flexible location main cone 9 by the guiding vertex of a cone 6.
Using method:
Referring to Fig. 2, at first take off guiding pressure head 2, top at lower support pressure head 1, place the bearing 4 and the shaft block ring 5 that will assemble, shaft block ring 5 is down in order, and bearing 4 exists, and then the pressure head 2 that will lead is packed in the sleeve pipe of lower support pressure head 1, at this moment, bearing 4 and shaft block ring 5 are sleeved on the periphery of the Rotary-table 21 of guiding pressure head 2.
Referring to Fig. 3, pallet dolly 10 is moved to the assembly station location, the main cone 9 that to be pressed by centring ring 16 navigates to the center that press-fits of two dynamic compressors, and artificial the placement needs the superincumbent bearing inner race 12 of assembling, and fixedly pressure head 13 and seaming chuck 14 have been in place on this moment.
By cylinder button under two dynamic compressors, following cylinder crawl is up, and it is up to drive main cone elastic guide press-loading device integral body, aligns the spindle nose center hole of main cone 9 by the guiding addendum cone 6 in the mechanism, not only jack-up main cone 9 but also have function to the heart concurrently;
By two dynamic compressor upper cylinder half buttons, the upper cylinder half crawl is descending, treat that seaming chuck 14 enters main cone axle 15 and sets upright after the main cone 9, upper cylinder half stops pressurize, again by cylinder button under two dynamic compressors, crawl is up again for following cylinder, guiding pressure head 2 on the main cone elastic guide press-loading device is depressed and moves at this moment, leading simultaneously, the conical surface of Rotary-table 21 can strut shaft block ring 5 in the pressure head 2, by lower support pressure head 1 bearing 4 and shaft block ring 5 are pressed into main cone axle 15 simultaneously, and top bearing inner race 12 also can be pressed into main cone axle 15 simultaneously under the effect of seaming chuck 14, as shown in Figure 4, finishes assembling.
Next assembly work is waited in upper cylinder half and cylinder reposition respectively down.
