Abstract

The utility model discloses a contactless stroke controller which adopts an induction type proximity switch as a switch element, and a disc whose angle can change as an inductor (namely cam pieces) to form an angular displacement stroke control device. The utility model is composed of a shell, a rotor, a stator, and a junction box. The shell is a full seal type, and the rotor is composed of cam pieces mounted on a rotary shaft. The stator is composed of two rectangular beams which form 45 DEG angle with a centre line and a proximity switch mounted on the rectangular beam. A switch circuit is connected with a main control circuit by the junction box. The controller is contactless, and therefore, the arc can not be generated, the joint can not be burnt, and the operation is safe.

Description

The utility model relates to a kind of electrical control equipment, particularly contactless journey controller.
The journey controller of present common use is by the contact of dynamic and static contact or disengaging, makes the closed or disconnection of control circuit, comes control appliance to move by predefined parameter.This equipment is subjected to temperature, air themperature, height above sea level, the dust in air of running environment, the restriction of conditions such as vibration on every side.Simultaneously, between dynamic and static contact, often produce electric arc and contact or other element are burnt out.And, between dynamic and static contact, very easily be infected with dust or produce corrosion, cause loose contact, cause equipment operation out of control, cause serious equipment breakdown, cause heavy losses to production.
Utility model patent CN2123816U discloses a kind of contactless travel switch, formed by permanent magnet, induction annulus, transmission core body, electrical contact, switch pedestal and nonferromagnetic housing, the principle that the using permanent magnet different magnetic poles attracts each other, the action of drive electric contact is in order to detect at the ad-hoc location of workplace apart from interior two objects that relatively move.This device only plays on-off action, and can not control stroke.
The purpose of this utility model provides the contactless angular displacement journey controller of a kind of inductive type is greatly improved the reliability of Stroke Control.
Another purpose of the present utility model provides a kind of adjustment structure, is formed by making in relative rotation disk, realizes the coarse adjustment of stroke and position.
Another purpose of the present utility model is adjustable with being designed near the distance between switch and the disk, to realize the accurate adjustment of stroke and position.
Another purpose of the present utility model provides a kind of totally-enclosed contactless journey controller, can use in the rugged environment very much.
Another purpose of the present utility model is by controller being carried out multiple combination, realize multiple Transmission Ratio Control, satisfying the needs of different circuit and Chang Kai, normally closed contact.
According to the utility model, adopting inductive type is switch element near switch, forms the angular displacement journey controller with the disk (being cam bit) of variable-angle as inductor, is made up of casing, rotor, stator, terminal box.Casing is made of end housing, upper body, lower case, and the binding site of each housing seals with " O " shape band.Have the bearing housing that is used for supporting rotor in the housing of end; In upper body center line both sides, angle is 45 ° a oblique upper, has the rectangle peep-hole, and the polymethyl methacrylate window is housed in its groove.
Rotor is by being contained in the rotation axis on the bearing and forming by some groups of cam bits (being inductor, two every group) and hold down gag thereof that long key is sleeved on this.
Stator by supporting bracket, be contained in two rectangular beams of center line both sides and angle at 45 with it, afterbody connecting plate and two connecting rods are formed.Even number near the paired stagger arrangement of switch be contained in the rectangular beam of round-meshed both sides, each is tightened with cap fully up and down.Distance near switch on every side rectangular beam is the twice of cam bit distance.Equal the spacing of cam bit on the rectangular beam of both sides near the relative distance of switch, make both sides be equidistant stagger arrangement along pivot axis relative distance and arrange near switch.One end of rectangular beam is fixed on the supporting bracket, and the bottom of supporting bracket is just as the bearing bottom of the bearing housing of bearing housing.
Terminal box and lower house are cast together, and interior dress terminal block is fixed on the base plate that connects together with lower house.
According to contactless journey controller of the present utility model, principle according to inductance, by the rotation of rotor, the coil that adds terminal voltage in advance and the gap between the sheet metal are changed, by time interval of design electric current in the control circuit is with or without and reaches the control purpose.
According to the utility model, can be according to producing actual different needs, the various products of different specifications of design, 2~24 control circuits of manufacturing.
Because the utility model moves by electromagnetic induction, so can not produce electric arc between contact and the cam, also can not produce contact burning, or burn out the accident of other element.Because entire controller is in the security seal state, therefore be applicable in the adverse circumstances.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing 1 is a transverse sectional view of the present utility model.
Accompanying drawing 2 is a longitudinal sectional view.
As shown in Figure 1 and Figure 2, static position switch is formed in casing, rotor, stator, terminal box.
Casing is made up of end housing (1), upper body (2) and lower case (11), and its girth of faying face upper edge of housing each several part has rectangular channel, is stained with " O " shape rubber seal tape (10) in this groove.In end housing (1), be provided with bearing housing (7) and be used to install two cover bearings (8).Housing (2) center line both sides are respectively equipped with rectangle polymethyl methacrylate hagioscope (19) at an upper portion thereof, compress with rectangle flange circle (18) on it.
Rotor is by the main shaft (9) that is contained on the bearing (8), be contained in some groups of cam bits (13) (being inductor) on this by long key, every group two (example shown in Figure 2 is 4 groups, 8), and the compress adjusting device (12), (14), (15) of every group of cam bit are formed.
Stator is by being contained in the inboard supporting bracket (4) of end housing (1), be contained in controller center line both sides and be two rectangular beams (3) of 45 ° of angles with it with a series of circular holes, its head end cantilever type is fixed on the supporting bracket (4), afterbody is fishplate bar (17) in succession, and the connecting rod (16) that joins of connecting plate (11) is formed therewith.Supporting bracket (4) downside closely cooperates as bearing gland and bearing housing inwall.
Each inserts respectively in the circular hole of rectangular beam (3) near switch (5), tightens with being equipped with cap up and down.The distance near switch (5) of (3) is the twice of cam bit (13) spacing on every side rectangular beam, both sides are equidistant stagger arrangement near switch along center of rotation axis relative distance arrange, make to equal the spacing of cam bit near switch relative distance on the both sides rectangular beam (3).
