Abstract
The utility model relates to a controller, in particular to a position limiting switch controller for electric rolling door open and close machine, comprising a shell, wherein, an up travel switch, a down travel switch, a cam, a worm wheel and a worm are arranged inside the shell; the worm is connected with a driving axle of the electric rolling door open and close machine; and the worm wheel is fixed with the cam in a same shaft to link. The utility model has the advantages of novel and reasonable structural design, simple manufacture, convenient operation and adjustment, reliable performance and long service life.
Description
Technical field
The utility model relates to a kind of controller, in particular for the controller of the limit switch of control electric rolling door headstock gear work.
Background technology
At present, known rolling door has two kinds, and a kind of is manual, and another kind is electronic, and the rise and fall of electric rolling door are by Electric Machine Control, and the upper and lower location of rolling door is by the travel switch control of motor.During work, driving travel switch driving shaft (horizontal hair) by motor shaft rotates, the travel switch driving shaft is provided with the horizontal hair nut of raming, the card baffle plate is snapped in, withdraws from horizontal hair rams in the nut groove, horizontal hair is ramed, and nut is left and right to be moved, collide left and right travel switch, control the duty of motor, reach the upper and lower location of rolling door.The headstock gear limit switch control mode of the electric rolling door of this structure, the horizontal hair nut of raming comes off easily, and easily breaks travel switch, complex structure, and application life is not long.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of controller of cam structure of worm and gear transmission, and this controller can not only be controlled the location up and down of rolling door, and can accurately locate.
The technical scheme that its technical problem that solves the utility model adopts is: electric rolling door headstock gear limit switch controller, have housing, and upper and lower stroke switch is set in the housing, cam, worm and gear, worm screw connect the power transmission shaft of electric rolling door headstock gear, worm gear and the coaxial fixedly interlock of cam.
The beneficial effects of the utility model are that structure design is new reasonable, manufacturing is simple, operate and debug convenience, dependable performance, long service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1.
Among the figure: 1. housing, 2. travel switch, 3. cam, 4. worm gear, 5. worm screw up and down.
The specific embodiment
Electric rolling door headstock gear limit switch controller as shown in Figure 1 and Figure 2, has housing 1, upper and lower stroke switch 2 is set in the housing 1, travel switch 2 is triggered by cam 3, the transmission of cam 3 realizes that by worm gear 4 worm screws 5 worm screw 5 connects the power transmission shaft of electric rolling door headstock gear, worm gear 4 and cam 3 coaxial fixedly interlocks, the total number of teeth in engagement of worm gear 4 worm screws 5 is by calculating, and the rotation number of turns of the worm screw 5 when drive of motor makes the arrival upper-lower position of rolling door can make worm gear 4 turn around to calculate and decide.
When opening the door, connect power supply, driven by motor worm screw 5 is rotated, and worm screw 5 drives worm gears 4 and rotates, and worm gear 4 drives cams 3 and rotates, and when rolling door arrived and goes up most, the protruding place of cam 3 triggered travel switch 2, and motor is quit work, and door has just been held successfully; At closing time, connect power supply, driven by motor worm screw 5 is rotated, and worm screw 5 drives worm gear 4 and rotates, and worm gear 4 drives cam 3 and rotates, and when rolling door arrived at the most following, the protruding place of cam 3 triggered travel switch 2, and motor is quit work, and door has just shut.
