Abstract
The invention discloses an electric cam, which can regulate a position without opening a cover of equipment. The electric cam mainly comprises a cam body (1), convex rings (2), drive shafts (3), micromotors (4) and the like, wherein the micromotors (4) drive corresponding convex rings (2) to rotate any angle relative to the cam body by corresponding worms (5), corresponding worm gears (6) and corresponding drive shafts (3). The whole electric cam can rotate any angle about a cam shaft (9). The convex ring (2) of the electric cam is used for pressing a travel switch down to fulfill the aim of protecting a system. Each micromotor (4) of the electric cam can drive a corresponding convex ring (2) to rotate any angle relative to the cam body by own worm (5), own worm gear (6) and own drive shaft (3) to ensure that a certain convex ring (2) can press the travel switch down when the cam body of the electric cam is at any angle to fulfill the aim of regulating the position of the cam without opening the cover of the equipment.
Description
Technical field
The present invention relates to a kind of device final protective effect, that the depression stroke switch cuts off electrical source of power that has been used for, relate in particular to a kind of motorized cams.
Background technology
Any mechanical mechanism that has travel limits on the current market; be typically electric actuator; it all has stroke restricting means usually; last pipe protection line as system; when the controllable silicon of control motor punctures, relay contacts is clung or the situation of single chip microcomputer halt under, can cause motor to rotate and can't stop to a direction all the time, the effect of mechanical mechanism stopping means is that cam is at extreme position depression stroke switch; cut off motor power, finish last protective effect.
In order to make stopping means working properly, must adjust the setting angle of cam, make it to depress positive and negative two travel switches just at positive and negative two extreme positions respectively, reach the purpose of protection.In many products, must adopt the non-intrusion type adjustment, that is to say and do not open cover, can not adjust the position of cam with screwdriver and spanner.The position of common cam is adjusted with screwdriver and spanner, can not satisfy the requirement that non-intrusion type is adjusted.
Summary of the invention
According to above-mentioned technical problem, the present invention proposes a kind of lid that need not open equipment, just can adjust the position motorized cams, mainly form, it is characterized in that electrical micro-machine carries out arbitrarily angled rotation by worm screw, worm gear and drive shaft bulge loop with respect to cam body by cam body (1), bulge loop (2), driving shaft (3), electrical micro-machine (4), worm screw (5), worm gear (6), brush (7), slip ring (8), camshaft (9), travel switch (10), base plate (11).The integral body of motorized cams can be carried out arbitrarily angled rotation around camshaft, and the bulge loop of motorized cams is used for the depression stroke switch, reaches the purpose of protection system.Each electrical micro-machine of motorized cams can carry out arbitrarily angled rotation with respect to cam body by the corresponding bulge loop of worm screw, worm gear and drive shaft separately, guarantees that the body of motorized cams can have bulge loop depression stroke switch arbitrarily angled.One group of slip ring is equipped with in the lower surface of cam body, and one group of brush is housed on base plate, and external power source can be given the electrical micro-machine that is installed in cam body power supply by brush, slip ring.Worm screw is a single start worm, and its lead angle is spent 10 fens less than 3, possesses auto-lock function, guarantees that when electrical micro-machine did not change, bulge loop was with respect to the cam body transfixion.
The beneficial effect of motorized cams of the present invention is: the motorized cams of the present invention's design is on a cam body, several cam rings are installed, wherein the rarest two cam rings, be respectively applied for control direct limit position and inverse limit position, each cam ring can drive it by electrical micro-machine and rotate with respect to cam body, reach the lid of the equipment of need not opening, just can adjust the purpose of cam position.
