Abstract
The utility model relates to a swiveling jib type operation device of an adjustable idler which includes a shell, a transmission mechanism and a push rod. The transmission mechanism includes a guide piece sleeve, a guide piece and a rotary shaft with an adjusting arm; the guide piece sleeve is fixed on the step-shaped inner wall of the shell; the guide piece is penetrated in the guide piece sleeve and one end is mutually connected with the guide piece sleeve in a hooking way; the other end is mutually and closely contacted with the rotary shaft; the surrounding wall of the shaft section of the rotary shaft closely contacted with the guide piece at least includes a plane; one end of the push rod is mutually fixed with the guide piece; the other end is mutually and closely contacted with the operation end of a stroke switch; the push rod follows the transmission mechanism to coaxially slide in a reciprocated way. Compared with the prior art, the swiveling jib type operation device of an adjustable idler has a compact structure and excellent performances, works reliably and has a plurality of protection functions.
Description
Technical field
The utility model relates to the actuating of travel switch, particularly relates to a kind of adjustable roller pivoted arm type powder operation device.
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 in the utility model is exactly to provide a kind of adjustable roller pivoted arm type powder operation device for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of adjustable roller pivoted arm type powder operation device, it is characterized in that, comprise housing, transmission mechanism, push rod, described transmission mechanism comprises the rotating shaft of guide cover, guide, band adjustment 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.
Described rotating shaft interfixes with adjusting arm by clip-shaped piece, and this adjusts arm by bearing pin and the mutual riveted of a roller.
Compared with prior art, the utility model compact conformation, function admirable, reliable operation has the kinds of protect function.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of rotating shaft of the present utility model;
Fig. 3 is the A-A cutaway view of Fig. 2.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 1～3, a kind of adjustable roller pivoted arm type powder operation device, comprise housing 1, transmission mechanism, push rod 2, described transmission mechanism comprises the rotating shaft 5 of guide cover 3, guide 4, band adjustment arm 9, described guide cover 3 is fixed on the step inwall of housing 1, and described guide 4 is arranged in the guide cover 3, and an end overlaps 3 with guide and links 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; Described rotating shaft 5 interfixes with adjusting arm 9 by clip-shaped piece 11, and this adjusts arm 9 by bearing pin and a roller 10 mutual riveteds, so roller 10 can rotate around bearing pin.
After moving machinery touched the roller of powder operation device, 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.
Powder operation device of the present utility model 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 powder operation device push rod automatically, and the adjustable roller that does not influence powder operation device is adjusted arm assembly and continued to move to total travel.
Be provided with spring and sealing ring in the powder operation device of the present utility model, can effectively overcome the impulsive force that protection test is born, or the misoperation that produces at work.
