Embodiment
For content of the present utility model more easily is expressly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail,
As shown in Fig. 1 ~ 4, a kind of three station manipulation devices for gas-filling cabinet, it comprises bracing frame 12, sensitive switch 4, is bearing in two groups of transmission devices on bracing frame 12, each transmission device is provided with movably nut block 3, and nut block 3 contacts cooperation with sensitive switch 4, also comprise connecting plate 11 and output board 2, the two ends of connecting plate 11 are hinged on two nut block 3 by locating shaft 10 respectively, output board 2 is inserted on bracing frame 12, and the tail end of output board 2 is hinged on connecting plate 11 by welding axle 6, and output board 2 is arranged between two transmission devices.Like this, the distance of nut block 3 motions is connected to being determined apart from institute of two nut block 3 by stroke and the connecting plate 11 of transmission device fully, the accurate location that does not need sensitive switch 4, reached output of the present utility model accurate, stable, design comparison is effect flexibly, thereby guaranteed isolation, ground connection, the accurate control of turn on-switch three stations, the utility model is in the situation that meet instructions for use, designed part is simple and quantity is few, when greatly simplifying the internal structure of an organization, the wearing and tearing of parts had both been reduced, improved mechanical endurance again, and the distance that can be connected to by regulating connecting plate 11 two nut block 3 facilitates the designer to be improved according to the insulation distance of three stations of design.
For make nut block 3 in motion process relatively steadily and to 3 guide effects of nut block, thereby further improve the accurate control degree to isolation, ground connection, turn on-switch three stations, as shown in Fig. 1 ~ 4, bracing frame 12 upper supports have guide post 7, have the gathering sill 3-1 that inserts guide post 7 on nut block 3.
Transmission device can adopt following syndeton to realize, as shown in Fig. 1 ~ 4, transmission device comprises gear 1 and screw mandrel 5, and gear 1 is sleeved on screw mandrel 5, and screw mandrel 5 can be rotated to support on bracing frame 12, and nut block 3 is threaded connection with screw mandrel 5.Transmit the displacement of output board 2 by the nut-screw rod pair, transmission is more accurate, and stable, noise is also little, has improved to a certain extent the accurate control degree to isolation, ground connection, turn on-switch three stations.
Have the contact profile section matched with sensitive switch 4 on nut block 3, this contact profile section is formed by connecting by planar wall 3-2 and the chamfering wall 3-3 that is connected to planar wall 3-2 both sides.
Operation principle of the present utility model is as follows:
In force, motor is just driving screw mandrel 5 by gear 1, inhour rotatablely moves, be driven and do rectilinear motion on guide post 7 with the nut block 3 of screw mandrel 5 engagements, nut block 3 promotes output board 2 again and does rectilinear motion, the rectilinear motion of output board 2 is realized switch connection, isolation and three stations of ground connection, the complete thread segment length by screw mandrel 5 of distance of output board 2 motions, welding axle 6 positions between connecting plate 11 and output board 2 determine, respectively arrange nut block 3 on two screw mandrels 5, after nut block 3 moves to right end position, trigger the power supply that sensitive switch 4 cuts off chain drive (motor), screw mandrel 5 stops operating, the thread segment of screw mandrel 5 is longer, the distance of nut block 3 motions is also just longer, and two nut block 3 are connected by connecting plate 11, connecting plate 11 is guaranteed the relative position of two nut block, 3 motions, the distance of nut block 3 final motions is just fixing like this, therefore, because sensitive switch 4 characteristics vary with temperature, perhaps there is error sensitive switch 4 installation sites, as long as the thread segment length of screw mandrel 5 and connecting plate 11 are connected to the distance of two nut block 3 and all fix, the final position of nut block 3 just can not change, as can be seen here, the distance of nut block 3 motions is determined by the thread segment length of screw mandrel 5 and the distance of connecting plate 11 two ends perforates fully, the accurate location that does not need sensitive switch 4, the output that has reached operating means is accurate, stable, design comparison is effect flexibly.This operating means is in the situation that meet instructions for use, and designed part is simple and quantity is few, when greatly simplifying the internal structure of an organization, has both reduced the wearing and tearing of parts, has improved mechanical endurance again.
As shown in Figure 3, the positive hour hands of the screw mandrel 5 of below rotate, and after nut block 3 motions that are engaged with put in place, output board 2 is to right-hand horizontal movement one segment distance, and switch is in on-position.As shown in Figure 2, screw mandrel 5 inhours of below are rotated, after nut block 3 motions that are engaged with put in place, output board 2 is to left horizontal movement one segment distance, switch is in isolated location, same principle, as shown in Figure 4, the positive hour hands of the screw mandrel 5 of top rotate, after nut block 3 motions that are engaged with put in place, output board 2 is to left horizontal movement one segment distance, switch is in earthing position, as shown in Figure 2, screw mandrel 5 inhours of top are rotated, after nut block 3 motions that are engaged with put in place, output board 2 is to right-hand horizontal movement one segment distance, switch is in isolated location, obviously, this operating means has been realized the connection of switch, isolation and three stations of ground connection.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
