Compared with prior art, the device has the advantages of simple structure, stable performance and strong reliability.
Description
Technical field
The utility model relates to the travel switch powder operation device, particularly relates to a kind of linear motion rolling 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 unstable properties in actual applications, defective such as it is unreliable to work.In recent years, although many important control occasions all substitute with the foreign brand name product, because such product protection function is also perfect not to the utmost at present, on-the-spot abnormal running causes mechanism's clamping stagnation, moves malfunctioning the also comparatively common of fault that cause.
Summary of the invention
Technical problem to be solved in the utility model is exactly the linear motion rolling type powder operation device that a kind of simple in structure, stable performance, good reliability are provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: a kind of linear motion rolling type powder operation device, it is characterized in that, the housing that comprises transmission mechanism, push rod, upper and lower opening, two ends all offered the axle of axial groove about described transmission mechanism comprised, described axle is arranged in the housing, by the bearing pin riveted one roller is arranged in the groove of its upper end, and be exposed to outside the upper shed of housing, the upper end of described push rod interfixes with the lower end of axle, and described housing openings at two ends is suitable with axle and push rod respectively.
Be provided with the inwall of step in the groove of the lower end of described axle, the upper end of described push rod is fixed in push rod in the groove by a supporter of fixing with the step inwall, the middle part that is positioned at push rod is provided with the necked part of stepped portion and indent from top to bottom successively, be provided with spring one between this stepped portion and the supporter, be arranged with sealing ring on the described push rod, described sealing ring has a tight notch portion from top to bottom, the telescopic section and the part of becoming less severe, described tight notch portion is nested in the necked part of push rod, the internal diameter of described telescopic section is greater than the diameter of section of push rod appropriate section, the described part of becoming less severe presses by a strutting piece and is anchored on the inner walls, is provided with spring two between the lower end of this strutting piece and axle.
The lower end of described push rod offers axial groove, and this groove internal fixation has an adjustment screw.
The lower end of described push rod is provided with one and prolongs a radial direction to outdiffusion and be exposed to limited part outside the housing under shed, and the external diameter of this limited part is greater than the aperture relevant with the travel switch operating side.
Compared with prior art, the utlity model has following advantage:
1. actuating performance.The enough big excess of stroke is arranged and do not influence control and complete machine operating characteristics the switch element impulse stroke;
2. limit function.The Stroke Control of actuator push rod realizes spacing in the scope that switch element allows automatically.And this spacing roller that can not influence actuator continues to move to total travel;
3. protecting against shock protection.The dual spring structure makes mechanism realize steadily resetting, and satisfy operating characteristics requirements such as action force and release force, and can effectively overcome the impulsive force that protection test is born, or the misoperation that produces at work;
4. sealing.Between the push rod of axial motion and static shell be sealed in work the time do not have relative motion, thereby overcome the defective that the sealing that causes because of wearing and tearing comes into force.Owing to there is not frictional resistance, sealing is reliable simultaneously, has carried the useful life of complete machine.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of linear motion rolling type powder operation device, the housing 2 that comprises transmission mechanism, push rod 1, upper and lower opening, two ends all offered the axle 3 of axial groove about described transmission mechanism comprised, described axle 3 is arranged in the housing 2, by the bearing pin riveted one roller 4 is arranged in the groove of its upper end, and is exposed to outside the upper shed of housing 2, the upper end of described push rod 1 interfixes with the lower end of axle 3, and described housing 2 openings at two ends are suitable with axle 3 and push rod 1 respectively.
Be provided with the inwall of step in the groove of the lower end of described axle 3, the upper end of described push rod 1 is fixed in push rod 1 in the groove by a supporter 5 of fixing with the step inwall, the middle part that is positioned at push rod 1 is provided with the necked part of stepped portion and indent from top to bottom successively, be provided with spring 1 between this stepped portion and the supporter 5, be arranged with sealing ring 7 on the described push rod 1, described sealing ring 7 has a tight notch portion from top to bottom, the telescopic section and the part of becoming less severe, described tight notch portion is nested in the necked part of push rod, the internal diameter of described telescopic section is greater than the diameter of section of push rod appropriate section, the described part of becoming less severe presses by a strutting piece 8 and is anchored on the inner walls, is provided with spring 29 between the lower end of this strutting piece 8 and axle 3; The lower end of described push rod 1 offers axial groove, and this groove internal fixation has an adjustment screw 10; The lower end of described push rod 1 is provided with one and prolongs a radial direction to outdiffusion and be exposed to limited part 11 outside the housing under shed, and the external diameter of this limited part 11 is greater than the aperture relevant with the travel switch operating side; Described adjustment screw 10 can be collided with switch element 12; Be provided with back-up ring between the step inwall in the groove of supporter 5 and axle 3 lower ends, be provided with packing ring between the stepped portion of spring 1 and push rod 1.
After moving machinery touches the roller of powder operation device; active force passes to the push rod that has the kinds of protect function by one group of spring; the pull switch element makes contact closure or disconnection; reach the purpose of control; roller can rotate around bearing pin, can drive push rod simultaneously and make axially reciprocating and spacing by limited part.
