Abstract
The invention relates to a durability test device of switch and is characterized in that the device comprises a frame, a geared motor, a cam, a slide bar mechanism, an installation frame and a counting part; wherein the geared motor is fixed on the frame, the rotation axis of the motor is upward and fixed with the cam, the slide bar mechanism is fixed on the frame and is composed of a slide bar and a reset spring, one end of the slide bar and the surface of the cam are in fit to realize reciprocating movement, the other end of the slide bar is connected with the reset spring, the installationframe is fixed on the frame, and the counting part is fixed on the frame. The invention has the characteristics of high reliability, long service life and wide applicability.
Description
Technical field
The present invention relates to a kind of durability test device of electric tool switch, it utilizes the reducing motor driving cam means, by the break-make of push rod realization switch, cooperates counter to realize endurancing.
Background technology
The electric tool switch permanance is its important performance indexes, and durability test device is essential.Waste time and energy with manually testing, the pneumatic performer that waits is owing to itself life-span reason, and reliability is not high.The rotation of reducing motor is become rectilinear motion by specially designed cam, and pull switch opens and closes, and finishes test.
Summary of the invention
In order to overcome above-mentioned technical defective, the invention provides a kind of durability test device of electric tool switch.
To achieve these goals, the present invention adopts following technical scheme:
The durability test device of switch comprises: frame, reducing motor, cam, sliding bar mechanism, erecting frame, segment count; Described reducing motor is fixed on the frame; Electric machine rotational axis makes progress and is fixed with cam.Sliding bar mechanism is fixed on the frame, is made up of slide bar, back-moving spring; Slide bar one end cooperates with cam face realizes that slide bar moves back and forth, and passes through spring reset.Erecting frame is fixed on the frame, and adjustable positions is used for fixing tested electric tool switch.Segment count is installed on the frame.
Segment count is made up of the optoelectronic switch sum counter, and the optoelectronic switch of optoelectronic switch measures make-and-break signal and sends counter to and count.
The principle of work and the course of work that apparatus of the present invention relate to when using:
Tested electric tool switch is installed on the frame, and the installation site needs stroke position slide bar to shift position, the end onto by closure.Reducing motor rotating band moving cam rotates, and cam promotes slide bar and slides, and promotes fixing switch closure-disconnection and carries out continuously.Motor turns around each switch on and off once.The break-make frequency is regulated by reducing motor speed.Optoelectronic switch at slide bar by time record once.
The contrast of the present invention and prior art:
Have the reliability height, the life-span is long, the characteristics that applicability is wide.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is cam profile curve figure.
Among the figure: the 1-frame; 2-photoelectricity is near switch; 3-switch erecting frame; The 4-sliding bar mechanism; The 5-cam; The 6-reducing motor; 7-motor shaft diameter; The 8-roundlet; 9-great circle 10-eccentric distance
Specific embodiments
Describe specific embodiments of the invention with reference to the accompanying drawings in detail.
As shown in Figure 1, switch is installed on the erecting frame 3, adjusts mounting distance, and required stroke is the ultimate range of cam 5 and push rod 4 when making switch closure.With 3 top screw rod floatless switch.Cam 5 rotation is along with increasing to diameter, promotes the slide bar in the middle of the sliding bar mechanism 4, to left movement, and slide bar pull switch closure.Cam has been crossed the ultimate range slide bar and has been moved right, and switch disconnects, and finishes single test.Move in circles and carry out.Optoelectronic switch is counted according to the push rod pull switch.
As shown in Figure 2, the cam outer contour designs, and utilizes the eccentric distance 10 of roundlet 8, great circle 9, when realizing around 7 rotations of motor shaft diameter, and the variation of vertical range.The distance size is the poor of big roundlet 9,8 diameters.
At last, should be pointed out that above embodiment only is the more representational example of the present invention.Obviously, technical scheme of the present invention is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
Claims (2)
