Abstract
The utility model relates to a machinery for a water nozzle changeover switch life tester, comprising a control motor, which is characterized in that: the control motor is fixed on a worktable through a motor frame; a cam is fixed on the rotating shaft of the control motor; a spring bracket fixed on the motor frame is arranged above the cam; a lift is arranged below the cam; a spring is arranged between the spring bracket and the lift; an inward slide bar is arranged in the middle of the lift, and a fixture is fixed at the lower part of the slide bar. The utility model has the advantages of simple structure, good control performance and accurate positioning since the power is supplied by a stepping motor, and no noise of the rotating stepping motor, so that the working environment of the operator is improved.
Description
Technical field
The utility model relates to a kind of mechanical hook-up of water nozzle switch life test machine.
Background technology
The durability test of water nozzle is that the spool in the water nozzle is made durability test, requirement is installed in water nozzle on the test loop, under certain hydraulic pressure and certain hot water temperature and cold water temperature, open spool, regulate flow within the specific limits, switch action, alternate supplies hot and cold water, reach certain number of times, finish durability test.Existing water nozzle switch durability test adopts pneumatic element, and in use, air pressure change by its two ends realizes because the piston of cylinder moves, and sensitivity is lower, locatees not accurate enough; And the noise of pneumatic element is bigger, is operated in over a long time in the noisy environment, and is unfavorable to health; Cylinder is easy to wear in addition, need often keep in repair.
The utility model content
The purpose of this utility model is to propose the mechanical hook-up of a kind of accurate positioning and muting water nozzle switch life test machine.
The utlity model has the control motor, the control motor is fixed on the worktable by motor cabinet, be fixed with cam in the rotating shaft of control motor, the top of cam is provided with the spring(-supported) mount that is fixed on the motor cabinet, the cam below is provided with argues for the sake of arguing, spring(-supported) mount and argue for the sake of arguing between be provided with spring, the central authorities of arguing for the sake of arguing are fixed with downward slide bar, anchor clamps are connected the bottom of slide bar.
Above-mentioned control motor adopts stepper motor.
Be fixed with the pulley base that opening makes progress on above-mentioned the arguing for the sake of arguing, the pulley in the pulley base touches cam.
Be provided with slider block on above-mentioned motor cabinet, slide bar and slider block are dynamically connected.
The utility model provides power by stepper motor, so simple in structure; Stepper motor is a kind ofly to convert electric impulse signal the executive component of straight line or angular displacement to, motor whenever receive a pulse signal just fortune move a step, the cumulative errors of the moving circle of revolution is zero, so control performance is good, accurate positioning; The rotation noiseless of stepper motor improves the residing environment of operating personnel; The utility model structure is simple in structure and not fragile.

Embodiment
The utility model tool is controlled into motor 1, control motor 1 adopts stepper motor, stepper motor 1 is fixed on the worktable 3 by motor cabinet 2, be fixed with cam 5 in the rotating shaft 4 of stepper motor 1, the top of cam 5 is provided with the spring(-supported) mount 6 that is fixed on the motor cabinet 2, and cam 5 belows are provided with argues for the sake of arguing 7, spring(-supported) mount 6 and argue for the sake of arguing and be provided with spring 8 between 7,7 central authorities of arguing for the sake of arguing are fixed with the pulley base 11 that opening makes progress, and pulley 12 is connected on the pulley base 11 by minor axis 15, and pulley 12 touches cam 5.Argue for the sake of arguing 7 central authorities are fixed with downward slide bar 9, are provided with slider block 13 on motor cabinet 3, and 13 of slide bar 9 and slider blocks are connected by line style bearing 14.The bottom of slide bar 9 has screw thread, anchor clamps 10 are the chuck of bottom opening, chuck 10 is threaded in the bottom of slide bar 9, slide bar 9 and above chuck 10, be connected with fastening screw nut 10-1, can suitably adjust the position of chuck 10 on slide bar 9, play the distance of regulating chuck 10 and water nozzle switch 18-1, chuck 10 is provided with trip bolt 16.
The work of use the utility model, water nozzle 18 is fixed on the support 17 of worktable, stepper motor 1 drives cam 5 and rotates, cam 5 moves downward gradually by the pulley 12 and the 7 promotion slide bars 9 of arguing for the sake of arguing, slide bar 9 drives switch 18-1 by chuck 10 and moves down, switch is closed, and this moment, spring 8 was in maximum open configuration.When cam 5 is rotated further, under spring 8 effects, argue for the sake of arguing 7 along with on lift, slide bar 9 drives chucks 1 and rises, and resets fully until spring 8, switch is opened, and finishes once circulation.
Water nozzle switch life test machine is provided with electric device, and starting, the number of times that stops, rotates are controlled by electric device.
