Abstract
The invention relates to a rolling pivoted-arm actuator for a travel switch, comprising a casing, a transmission mechanism and a pushing rod. The transmission mechanism comprises a guiding element set, a guiding element and a rotating shaft with a pivoted arm. The guiding element set is fixed on a step-shaped inner wall of the casing. The guiding element is perforated in the guiding element set. One end of the guiding element is mutually hooked with the guiding element set, and the other end is in contact with the rotating shaft mutually and tightly. The surrounding wall of a segment of the rotating shaft in tight contact with the guiding element at least comprises a plane. One end of the pushing rod is fixed with the guiding element, and the other end is in contact with an operating end of the travel switch mutually and tightly. The pushing rod slides axially in a reciprocating way along with the transmission mechanism. Compared with the prior art, the rolling pivoted-arm actuator for the travel switch has the advantages of compact structure, perfect performance, reliable working and multi-protecting functions.
Description
Technical field
The present invention relates to the actuating of travel switch, particularly relate to a kind of rolling pivoted-arm type actuator that is used for travel switch.
Background technology
Travel switch can be transformed into electrical signal with mechanical movement, is used for controlling mechanical action or program control, therefore is used widely in control system.Exist the operating characteristics instability in actual applications, defective such as it is unreliable to work.Because defencive function improves on-the-spot abnormal running not to the utmost and causes mechanism's clamping stagnation, the malfunctioning fault that causes of moving happens occasionally.
Summary of the invention
Technical problem to be solved by this invention is exactly to provide a kind of rolling pivoted-arm type actuator that is used for travel switch for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: a kind of rolling pivoted-arm type actuator that is used for travel switch, it is characterized in that, comprise housing, transmission mechanism, push rod, described transmission mechanism comprises the rotating shaft of guide cover, guide, band pivoted arm, described guide cover is fixed on the step inwall of housing, described guide is arranged in the guide cover, and an end and guide cover link mutually, the other end and rotating shaft are tightly touched mutually, and this rotating shaft comprises a plane at least with the perisporium of the shaft part that guide tightly touches mutually; One end and the guide of described push rod interfix, and tightly touch mutually the operating side of the other end and travel switch, and this push rod axially reciprocatingly slides with transmission mechanism.
Be equipped with axial opening on the described guide and on the push rod, described push rod is inserted in the opening of guide, and the opening internal fixation of this push rod has an adjustment screw, and tightly touch mutually the header planes of this adjustment screw and the operating side of travel switch.
Described guide and guide put and all are arranged with spring.
It is fan-shaped that the cross section of described shaft part generally is.
On the pivoted arm of described rotating shaft by bearing pin and the mutual riveted of a roller.
Compared with prior art, compact conformation of the present invention, function admirable, reliable operation has the kinds of protect function.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of rotating shaft of the present invention;
Fig. 3 is A-A cutaway view of Fig. 2.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Shown in Fig. 1～3, a kind of rolling pivoted-arm type actuator that is used for travel switch, comprise housing 1, transmission mechanism, push rod 2, described transmission mechanism comprises the rotating shaft 5 of guide cover 3, guide 4, band pivoted arm, described guide cover 3 is fixed on the step inwall of housing 1, described guide 4 is arranged in the guide cover 3, and an end and guide cover 3 link mutually, the other end and rotating shaft 5 are tightly touched mutually, and this rotating shaft 5 comprises a plane at least with the perisporium of the shaft part 6 that guide 4 tightly touches mutually; One end and the guide 4 of described push rod 2 interfix, tightly touch mutually the operating side of the other end and travel switch 7, this push rod 2 axially reciprocatingly slides with transmission mechanism, and push rod 2 can back and forth endwisely slip with rotating shaft 5, and its stroke is restricted by corner and relevant spacing.
Be equipped with axial opening on the described guide 4 and on the push rod 2, described push rod 2 is inserted in the opening of guide 4, and the opening internal fixation of this push rod 2 has an adjustment screw 8, and tightly touch mutually the operating side of the header planes of this adjustment screw 8 and travel switch 7; All be arranged with spring on described guide 4 and the guide cover 3; It is fan-shaped that the cross section of described shaft part 6 generally is; By bearing pin and a roller 10 mutual riveteds, so roller 10 can rotate around bearing pin on the pivoted arm 9 of described rotating shaft 5.
After moving machinery touched the roller of actuator, active force passed to the push rod that has defencive function by the rotating shaft by the movement locus design, and the pull switch element makes contact closure or disconnection, reaches the purpose of control.
Actuator of the present invention has limit function.The position-limit mechanism of being made up of guide and rotating shaft in the impulse stroke limit that switch element allows, is realized spacingly the Stroke Control of actuator push rod automatically, and the rolling pivoted-arm device that does not influence actuator continues to move to total travel.
Be provided with spring and sealing ring in the actuator of the present invention, can effectively overcome the impulsive force that protection test is born, or the misoperation that produces at work.
