Description
Technical field
The present invention relates to a kind of actuator of oil tank vehicle, particularly a kind of actuator of automatically controlledly can open, closing.Belong to mechanical engineering technical field.
Background technique
In oil tank vehicle, the application of actuator is comparatively wide, and its Main Function has been the opening and closing of each oil tank of oil tank vehicle.What the valve that current oil tank vehicle uses was common is manual ball valve, and manually rotary valve door-hinge realizes the opening and closing of valve.The function of oil tank opening and closing is realized by the opening and closing of valve.
Manual ball valve needs people just can open for starting, and automaticity is not high, and may appear at conveying people in transit and arbitrarily open the phenomenon of oil tank.
Summary of the invention
The object of the present invention is to provide a kind of actuator of oil tank vehicle, so that can the switch of electronic control oil tank vehicle tank, have solved the problem and the deficiencies in the prior art.
Technological scheme of the present invention: the actuator of a kind of oil tank vehicle of the present invention, it is primarily of motor, casing, cam, cam follower, position limit switch A, B, spring, spring stop and valve shaft and valve shaft housing composition.Position annexation between them is spring stop, position limit switch A, B, motor are fixed on casing, and valve shaft and valve shaft housing are connected by screw, and cam is connected with the output shaft of motor by mounting hole.Cam is connected with valve shaft housing by cam follower.Cam rotates under the drive of motor, and the rotating band moving cam push rod of cam moves reciprocatingly, by cam follower one end insert and exit valve shaft housing realize oil tank vehicle tank execute envelope and deblocking.
Described casing is box typed structure part, and the method by casting obtains, and its surface roughness and required precision are not high, arrange stiffening rib between box body wall and tank floor, to ensure that it has enough intensity.Casing is provided with mounting hole, and mounting hole obtains by the mode of bore hole.Mounting hole mainly contains two functions: be casing can be fixedly mounted on car body by mounting hole on the one hand, valve shaft and motor can be fixedly mounted on above casing on the other hand.
Described cam and cam follower are common machine processing accessories, and its concrete size can be determined according to required magnitude of load.
The common reducing motor of DC selected by described motor, and the size that its concrete model hooks load according to gear is chosen.
Described spring is also optional component, and when valve shaft is not by locking, spring is in free state; When valve shaft is by locking, spring is in compressive state.When cam rotating band moving cam push rod moves upward, spring-compressed, cam follower insertion valve axle sleeve, valve shaft housing is by locking.When cam driven cam follower moves downward, spring makes cam follower move downward, until spring is in free state, now, cam follower exits valve shaft housing, and valve sleeve removes lockup state.
Described position limit switch A, B are also optional components, and it is mainly used to make motor stalls.When cam follower contacts with two travel position switches A, B, when making them close, motor stalls.
Described spring stop is telescoping structure part; Wherein play the effect of guiding groove on the one hand, ensure that cam follower can do straight reciprocating motion at valve shaft housing, and do not depart from, such cam follower can insert accurately or exit valve shaft housing.On the other hand, when making cam follower exit valve shaft housing when electric machine rotation, spring top board ensures spring under spring force, makes cam follower exit valve shaft housing.
Described valve shaft is circular shaft part, realizes oil tank vehicle emptying by the rotation of valve shaft.When valve shaft is by locking, valve shaft can not normally rotate, and staff cannot by the operation emptying of rotary valve door-hinge; When valve shaft removes locking, valve shaft can freely rotate, and staff can carry out emptying operation by rotary valve door-hinge.
Described valve shaft housing is cylindrical member, together with it is bolted on valve shaft.When cam follower one end insertion valve axle sleeve, valve shaft housing locking, now valve shaft also corresponding locking; When valve shaft housing is exited in cam follower one end, valve shaft housing removes locking, now valve shaft also corresponding releasing locking.
Wherein, cam is in the state of low speed underloading, so the leeway rule choice for use of cam etc. accelerate uniform retarded motion (i.e. parabolic motion), cam profile designs according to the characteristics of motion (comprising displacement diagram, velocity curve and acceleration diagram) of driven member cam follower.
Wherein, in the process of work, cam follower is by the drive locking of motor and unclamp valve shaft housing, realizes the deblocking of each oil tank of oil tank vehicle and executes envelope.
Advantage of the present invention is: be first that structure is simple.Whole actuator critical piece is less, and processing is simple, is easy to realize.Next is easy to operation.Driven by motor cam, cam and spring actuating cam push rod realize oil tank vehicle tank execute envelope and deblocking instead of the old actuator that goal valve is manually opened in dependence, save manpower.Finally be convenient to management.Effectively control the phenomenon that staff arbitrarily opens oil tank.

Embodiment
As Figure 1-Figure 5, the present invention is a kind of actuator for oil tank vehicle, and it forms primarily of motor 7, casing 11, cam 5, cam follower 9, position limit switch A4, position limit switch B6, spring 10, spring stop 3 and valve shaft 2 and valve shaft housing 1.Position annexation between them is spring stop, position limit switch A4, position limit switch B6 and motor 7 are fixed on casing 11, and valve shaft 2 and valve shaft housing 1 are connected by screw, and cam 5 is connected with motor output shaft 8 by mounting hole 12.Cam follower 9 contacts with cam 5, and motor 7 is with moving cam 5 to rotate, and cam 5 drives cam follower 9 to move reciprocatingly, cam follower 9 inserted by the other end and shift out valve shaft housing 1 realize oil tank vehicle tank execute envelope and deblocking.
The concrete executive mode of this actuator is, in the actuator of native system design, rotated by the rotating band moving cam 5 of motor 7, meanwhile, cam 5 drives cam follower 9 to move upward, now, cam follower 9 compression is in the spring 10 of free state, and in cam lever 9 one end, top insertion valve axle sleeve 1, valve shaft 2 is by locking, oil tank is in executes envelope state, and staff cannot carry out emptying operation by the operation of rotary valve door-hinge 2; When motor 7 receives deblocking signal, motor 7 rotates, band moving cam 5 rotates, because spring 10 is in compressive state, so spring 10 actuating cam push rod 9 moves downward, now, cam follower 9 exits valve shaft housing 1, and valve shaft 2 removes locking, and oil tank is in unset state, valve shaft 2 can rotate freely, and staff can carry out emptying operation by rotary valve door-hinge 2.
The above, when executing envelope signal, send a signal rotated can to motor 7, now, the rotating band moving cam 5 of motor 7 rotates, cam 5 again actuating cam push rod 9 moves reciprocatingly, until cam follower 9 touches position limit switch A4 and makes it close, now motor 7 stops operating, in cam follower 9 the other end insertion valve axle sleeve 1, valve shaft 2, by locking, can not rotate, and oil tank is in executes envelope state.When applying deblocking signal, send a turn signal still can to motor 7, now motor 7 rotating band moving cam 5 rotates, because now spring 10 is in compressive state, so cam follower 9 moves under the promotion of spring 10, until cam follower 9 touches position limit switch B6 and makes it close, now motor 7 stops operating, cam follower 9 exits valve shaft housing 1 under the effect of spring 10 thrust, and valve shaft 2 can freely rotate, and oil tank is in unset state.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
