Advantage and disadvantage of the present invention, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below, these embodiments, only provide as an example with reference to accompanying drawing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As depicted in figs. 1 and 2, the present invention includes clutch shaft 1, rocking key 2, attachment ring 3, two stage clip clamping devices 4 and operating device 5, clutch shaft 1 right-hand member is fixedly connected with bent axle 6 left end, and clutch shaft 1 left end puts in final drive gear center hole 7.Clutch shaft 1 left end has axial groove 11, rocking key 2 is embedded in wherein, rocking key 2 left end and clutch shaft 1 left end termination hinged, attachment ring 3 is positioned at final drive gear center hole 7, be enclosed within clutch shaft 1 and rocking key 2, rocking key 2 two ends are located by flange 21.Rocking key 2 right-hand member upper and lower sides is being vertically fixed on two stage clip clamping device 4 the inner clampings of clutch shaft 1 upper and lower sides respectively; Laterally extend bump bonding 22 in the middle part of rocking key 2, operating device 5 is positioned on the downside of clutch shaft 1.
Stage clip clamping device 4 comprises stage clip sleeve 41, stage clip stem stem 42 and stage clip 43, stage clip 43 and stage clip stem stem 42 are arranged in stage clip sleeve 41, stage clip 43 is enclosed within stage clip stem stem 42, two stage clip sleeve 41 the inners are separately fixed at the upper and lower sides of clutch shaft 1, and stage clip sleeve 41 outer end is stretched out in stage clip stem stem 42 outer end; Stage clip stem stem 42 the inner of two stage clip clamping devices 4 is resisted against the upper and lower sides of rocking key 2 right-hand member respectively.On the upside of clutch shaft 1, stage clip 41 elastic force of stage clip clamping device 4 is 1.9 ~ 2.1 times of stage clip 41 elastic force of stage clip clamping device 4 on the downside of clutch shaft 1, and the present embodiment is 2 times.Because stage clip 41 elastic force on the upside of rocking key 2 right-hand member is greater than the elastic force of stage clip 41 on the downside of rocking key 2 right-hand member, rocking key 2 clockwise direction lower swing, thus rocking key 2, attachment ring 3 and final drive gear center hole 7 inner peripheral surface three are linked into an integrated entity, clutch shaft 1 engages with final drive gear 7, and clutch shaft 1 is with dynamic crankshaft 6 to complete pressure-sizing.
Operating device 5 is arranged on the downside of clutch shaft 1, comprises operating grip 51, fork back shaft 52 and fork 53, and termination, horizontally disposed fork back shaft 52 two ends is supported on dunnage 54 upper end respectively, on dunnage 54 lower end fixed main body side plate 8.Operating grip 51 upper end is vertical soldered with fork back shaft 52 one end, and torsion spring 55 is arranged on fork back shaft 52 left end, and on the left of operating grip 51 and between dunnage 54 inner side surface.Fork 53 upper end is crescent shape, and lower end is straight plate 53, and described straight plate 531 lower end is fixed in the middle part of clutch shaft 1.Fork 53 plane acutangulates crossing with operating grip 51.
After fork 53 turns to plumbness, be locked on fuselage side plate 8 by the lock screw 56 through the straight plate in its lower end, toggle rod type underdrive coining press clutch lock is fixed on disengaged condition, and toggle rod type underdrive coining press quits work.
After toggle rod type underdrive coining press starts, the operating grip 51 of operating device 5 of the present invention is in plumbness, and because fork 53 plane acutangulates crossing with operating grip 51, fork 53 is outward-dipping, and stage clip clamping device 4 cannot be contacted, the present invention is in bonding state.Stage clip 41 on the upside of rocking key 2 right-hand member presses down rocking key 2, make its clockwise direction lower swing, thus rocking key 2, attachment ring 3 and final drive gear center hole 7 inner peripheral surface three are linked into an integrated entity, clutch shaft 1 engages with final drive gear 7, clutch shaft 1 is with dynamic crankshaft 6 to rotate, and driving slide block moves up and down to go round and begin again and carries out pressure-sizing.
Outwards pull operating grip 51, fork 53 is driven to turn to plumbness, stage clip stem stem 42 lower end on the downside of rocking key 2 right-hand member is backed down on the upside of the crescent shape of fork 53, rocking key 2 is rotated counterclockwise around its hinged axle center, rocking key 2, attachment ring 3 and final drive gear center hole 7 inner peripheral surface three are disengaged, clutch shaft 1 and bent axle 6 stop operating, and slide block stops mobile.
In addition to the implementation, the present invention can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of application claims.
