The movable link 3 of boosting mechanism 10 forms tabular, be fixed on together with positioning part 2 assembling device 1 arrange supporting post 8 on position be supported for can be in vertical free lifting.In addition, on movable link 3, via the chain (chain or line) 82 being wound on pulley 811, be connected with counterweight 85, the fixed component 80 that this pulley 811 is fixed on supporting post 8 upper ends is supported for and can freely rotates.In addition, the upper surface at Fig. 1 of movable link 3, is fixed with and the cardinal extremity of operating stem 4 can be supported for to the supporting frame 30 freely rotating.
At the cardinal extremity of operating stem 4 through having supported 30 and support and at the upwardly extending back shaft 41 in side that runs through the paper of Fig. 1, thus, operating stem 4 being supported for and can freely rotating by movable link 3 by back shaft 41.The handle 42 of being controlled by operator when the free end of operating stem 4 is provided with at assembling break 100 in addition.In addition, the driven roller 45 as follower is installed on operating stem 4, the axle that driven roller 45 can extend abreast around the bearing of trend with back shaft 41 freely rotates.In the present embodiment, driven roller 45 is for example configured in the vertical direction of the bearing of trend with operating stem 4 and back shaft 41 separations (interval between both axle center) G.
In addition, the cam member 5 of boosting mechanism 10 forms tabular, and the upper end portion in Fig. 1 is fixed on fixed component 80(supporting post 8) upper and be maintained state of rest.In addition, in the side of cam member 5, be formed for respectively guiding straight line motion guide surface 50 and the camming surface 55 of driven roller 45, camming surface 55 have the auxiliary cam face 51 continuous with straight line motion guide surface 50 and with the continuous main cam face 52 of auxiliary cam face 51.
Straight line motion guide surface 50 is the tabular surface extending to vertical below from the top of cam member 5, to limit the mode that operating stem 4 rotates around back shaft 41, guides driven roller 45.; if under the state of the upper end butt in Fig. 1 of driven roller 45 and straight line motion guide surface 50; the counter clockwise direction of operating stem 4 in around back shaft 41 to Fig. 1 rotated; driven roller 45 rolls on straight line motion guide surface 50; mobile to vertical below; limit thus operating stem 4 and counterclockwise rotate in Fig. 1, and the movable link 3 being connected with operating stem 41 moves the distance suitable with the height of straight line motion guide surface 50 to vertical below.In addition, in the assembling device 1 of present embodiment, not shown block is set, described block make operating stem 4 around back shaft 41 to Fig. 1 in clockwise direction while rotating, in driven roller 45 and the stage of the upper end butt of straight line motion guide surface 50, operating stem 4 is stopped.
As shown in Figure 1, the auxiliary cam face 51 that forms camming surface 55 is in the straight line motion guiding Graph-Oriented from extending in vertical, counterclockwise to tilt smaller angle [alpha] (for example, the degree of 3～10 °) and the tabular surface that forms.In addition, the main cam face 52 that forms camming surface 55 is curved surfaces that extend on (right side figure) from the lower end of auxiliary cam face 51 to side, and the height setting by main cam face 52 in vertical is for being less than significantly the height of auxiliary cam face 51 in vertical.Thus, if making the counter clockwise direction of operating stem 4 in around back shaft 41 to Fig. 1 under the state of driven roller 45 and the upper end butt of auxiliary cam face 51 rotates, driven roller 45 rolls on auxiliary cam face 51, bearing of trend (tiltedly below) to this auxiliary cam face 51 is mobile, allow thus operating stem 4 counterclockwise to rotate in Fig. 1, and the movable link 3 being connected with operating stem 4 move the distance suitable with the height of auxiliary cam face 51 in vertical downwards.In addition, if under the state of driven roller 45 and the starting point butt of main cam face 52, operating stem 4 is counterclockwise rotated in around back shaft 41 to Fig. 1, driven roller 45 rolls on main cam face 52, bearing of trend (tiltedly side) to this main cam face 52 is mobile, allow thus operating stem 4 counterclockwise to rotate in Fig. 1, and the movable link 3 being connected with operating stem 4 move the distance suitable with the height of main cam face 52 to vertical below.
As mentioned above, if applying power to the handle 42 as force position is that input load counterclockwise rotates operating stem 4 in around back shaft 41 to Fig. 1, as the driven roller 45 of fulcrum, on the straight line motion guide surface 50 of static cam member 5 and camming surface 55, roll, follow in this, movable link 3 is mobile to vertical below together with becoming the back shaft 41 of point of action.In addition, the camming surface 55 that comprises auxiliary cam face 51 and main cam face 52 forms, along with operating stem 4 in Fig. 1 counterclockwise (direction) rotate, amount of movement in vertical of back shaft 41 and movable link 3 and the amounts of rotation of this operating stem 4 are that handle 42 diminishes around the ratio between the rotation length of back shaft 41.Therefore, according to boosting mechanism 10, along with operating stem 4 rotates in counter clockwise direction in Fig. 1, it is large that the reduction factor (reduction factor) (amount of movement of the amounts of rotation/movable link of operating stem 4) of the input load that this operating stem 41 of subtend applies becomes, therefore, can change the input load that puts on operating stem 4 into larger output loading, and export from movable link 3 via back shaft 41.
The main cam face 52 of cam member 5 then, is described.Fig. 3 and Fig. 4 mean the schematic diagram of the position of the back shaft 41 when driven roller 45 rolls on main cam face 52.In Fig. 3 and Fig. 4, main cam face 52 is represented by thick line, between auxiliary cam face 51 and main cam face 52, forms and relaxes curved surface.As shown in Figure 3, main cam face 52 forms, along with making operating stem 4 to counterclockwise rotating in Fig. 1, back shaft 41 movable links 3 of operating stem 4 when counterclockwise rotating predetermined angular (constant angle) in Fig. 1 are diminished to the amount of movement (" da " in Fig. 3, " db ", " dc ", " dd ") of vertical below.; along with operating stem is to counterclockwise rotating in Fig. 1, the ratio (" da/R ", " db/R ", " dc/R ", " dd/R ") with respect to amounts of rotation (handle 42 is around the rotation length of the back shaft 41) R of the operating stem corresponding with afore mentioned rules angle 4 diminishes to the amount of movement of vertical below for back shaft 41 and movable link 3.
At this, for along with operating stem 4 rotates and makes back shaft 41 ratio with respect to the amounts of rotation of this operating stem 4 diminishes to the amount of movement of vertical below to direction, the main cam face 52 of present embodiment forms Fig. 4 middle distance d
