Abstract
The utility model discloses a machinery for nozzle hot and cold fatigue testing machine, which comprises a frame; wherein, a rotary control motor is fixed on the bottom surface of a work station for the frame; a rotating shaft of the rotary control motor is upward and is provided with a rotary arm at the top part; a haulage rope which is guided by a pulley block and can be opened and closed is arranged on the rotary arm; a haulage control motor of controlling the haulage rope is fixed on the work station; two water tanks are arranged at the lower part of the frame; wherein, a heating element is arranged in one water tank. The utility model has the advantages of accurate location, no noise when the control motor works, simple structure, convenient maintenance and long service life due to adopting the control motor.
Description
Technical field
The utility model relates to the mechanical hook-up of the cold and hot fatigue tester of water nozzle.
Background technology
The cold and hot torture test of water nozzle is after water nozzle at first being placed-20 ℃ of environment some hrs, put into 100 ℃ of environment some hrs rapidly, more than 24 hours be a circulation, need circulation continuously for several times, again water nozzle is alternately immersed each certain hour in 80 ℃ of hot water and the room temperature water, need carry out certain number of times continuously.The at present domestic life test machine that has the water nozzle that utilizes pneumatic element to connect flexible pipe, in use, air pressure change by its two ends realizes because the piston of cylinder moves, 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 the cold and hot fatigue tester of noiseless water nozzle.
For achieving the above object, the utlity model has frame, on the worktable bottom surface of frame, be fixed with the Spin Control motor, the rotating shaft of Spin Control motor upwards and at its top is fixed with pivoted arm, pivoted arm is provided with by pulley blocks guiding and retractable traction rope, the traction control motor of control traction rope is fixed on the worktable, and the bottom of frame is provided with two water tanks, wherein is provided with heating element in the water tank.
Above-mentioned Spin Control motor adopts stepper motor, and the traction control motor adopts servomotor.
The outside of the rotating shaft of above-mentioned Spin Control motor is provided with shaft seat, is connected by rolling bearing between shaft seat and the rotating shaft.
Described pulley blocks is made up of four pulleys, and first pulley is connected on the main shaft of traction control motor, and second pulley is arranged on the pulley bracket of pivoted arm below, and the 3rd pulley is arranged on the inner of pivoted arm, and the 4th pulley is arranged on the outermost end of pivoted arm.
The utility model is owing to adopt the control motor that power is provided, stepper motor is a kind of executive component that electric impulse signal is converted to straight line or angular displacement, motor whenever receives a pulse signal and moves a step with regard to fortune, the cumulative errors of the moving circle of revolution is zero, so accurate positioning, and control basic noiseless during machine operation; Owing to adopt the control motor, one-piece construction is simple, and is easy to maintenance, long service life in addition.
