The specific embodiment
As shown in Figure 3, pressing machine preferred embodiment of the present invention is a flashlight conduction trim ring pressing machine, and it comprises base 3, has the support 1 of top board 2, is arranged on the press-loading apparatus 4 on the base 3, and support 1 is installed on the base 3, and press-loading apparatus 4 is arranged on the base 3; Press-loading apparatus 4 comprises hydraulic jacking device 5 and is arranged on the press-fitting tool at hydraulic jacking device 5 tops, press-fitting tool comprises the base plate 7 that is installed in the hydraulic jacking device top and is arranged on several projections 8 on the base plate 7 that the top of projection 8 is provided with and the suitable boss 9 of flashlight conduction trim ring shape.
In the preferred embodiment of the present invention, hydraulic jacking device 5 is manual hydraulic jack, referring to Fig. 3, manually hydraulic jack comprises oil-hydraulic cylinder 50, piston 51, manual adjustments lever assembly 6, oil pressure valve 52, and the base plate 7 of press-fitting tool is installed in the top of piston 51.
Referring to Fig. 4, in the preferred embodiment of the present invention, press-fitting tool also comprises location upper plate 13, location upper plate 13 is provided with several and the suitable locating hole 14 of flashlight shell, location upper plate 13 is used for preventing moving press-fiting the process flashlight shell, assurance press-fits quality, the Assembling Production of simultaneous adaptation mass.
When press-fiting, conduction trim ring 10 is set on the boss 9, and the external diameter of boss 9 is suitable with the internal diameter of conduction trim ring 10.In the present embodiment, flashlight housing 11 is made by plastic material, internal structure according to flashlight housing 11, be pressed on the bottom 12 of torch 11 head cavities in order to guarantee to conduct electricity trim ring 10, the height of boss 9 is less than the thickness of conduction trim ring 10, and the trim ring 10 that conducts electricity so just can be subjected to the pressure from manual hydraulic jack.Conduct electricity the annular that is shaped as of trim ring 10 in a preferred embodiment of the invention, the shape of conduction trim ring 10 is triangle, square or other shapes also, and the shape of boss 9 is then suitable with it, also triangle, square or other shape.
Press-fit for convenience finish after pickup, in the preferred embodiment of the present invention, also comprise the guide rail 15 that is arranged on the base 3, referring to Fig. 7, press-loading apparatus 4 is arranged on the guide rail, can move on guide rail 15.
Hydraulic jacking device 5 in the preferred embodiment of the present invention is hydraulic jack also, is driven by the hydraulic oil of other access, is convenient to realize automated production, further enhances productivity.
Press-fit mechanism and the using method that example further specifies the preferred embodiment of the present invention below in conjunction with actual.The pressing machine of the preferred embodiment of the present invention is that 4 companies adorn flashlight conduction trim ring pressing machine, during use, hold down gag 4 is shifted out support, 4 conduction trim rings 10 are set in respectively on 4 boss 9, then 4 torch housing 11 heads are set on 4 projections 8 down, and conduction trim ring 10 is contacted with the bottom 12 of torch housing 11 head cavities, as shown in Figure 8; Location upper plate 13 is set on the afterbody of housing 11.Workpiece place ready after, press-loading apparatus 4 is moved into supports 1, make press-loading apparatus 4 be in the below of top board 2, as shown in Figure 5.Screw the oil pressure valve 52 of hydraulic jack then, depress adjustment (adjusting) lever 61 repeatedly with hand, referring to Fig. 6 and Fig. 7, the piston 51 of hydraulic jack just slowly rises, the drive press-fitting tool moves upward, direction as shown in arrow 16, up to the afterbody roof pressure of torch housing 11 on top board 2, further push adjustment (adjusting) lever 61 again, till the top is motionless.At this moment, on the bottom 12 of the just firm head cavity that is fitted in torch housing 11 of conduction trim ring 10.In order to prevent that overvoltage from causing damaging by pressure torch housing 11, the minimum range that projection 8 tops can reach to top board 2 lower surfaces equals to press-fit when finishing conduction trim ring 10 end faces to the distance of torch housing 11 tail ends.Press-fit finish after, the valve knob 52 of the hydraulic jack of outwarding winding, piston 51 just moves downward the withdrawal oil cylinder, drives press-fitting tool and press-fit parts to move downward.Can shift out press-loading apparatus 4 when piston 51 moves down, direction as shown in arrow 17 after shifting out, is taken off location upper plate 13, takes off the flashlight housing then and gets final product.Screw the valve 52 of hydraulic jack then, placement press-fits workpiece, enters another the circulation that press-fits.
Pressing machine of the present invention is suitable for being fitted in quoit on the plastic cement structural member or containing on the metal objects of part plastic cement, be particularly suited for the press-fiting of conducting metal trim ring of portable lamp such as flashlight, press-fit effectively, assembling is firm, support large batch of compression fit work, the production efficiency height.
In conjunction with the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of forms, these all belong within the protection of the present invention.
