Abstract
The utility model relates to a novel spring fast pressing tester which is formed from a motor, crank rotary mechanisms and a spring test stand which are assembled on a machine frame in a matching mode. A main motor adopts a speed regulating motor, and the main motor and a main drive shaft are fixedly arranged on the machine frame in an axial lead parallel mode. A main belt pulley, an energy storage flywheel and the driving end of a clutch are integrally sheathed on the main drive shaft in a coaxial mode, and the driven end of the clutch is fixedly assembled with the main drive shaft. The tail ends of the cranks of the crank rotary mechanisms which are arranged at both ends of the main drive shaft in a matching mode are hinged with pressure spring sliding blocks which are arranged in erecting slide rails of the spring test stand in a matching mode, and in a prepressing device of the spring test stand, an axial lead of a prepressing screw rod which is matched and assembled with a prepressing seat is parallel to the erecting slide rails. A spring measured device is arranged between a spring bearing and placing seat of the prepressing seat and pressure spring heads of the pressure spring sliding blocks, and the speed regulating motor is started because the spring measured device on a double station is exerted with prepressing synchronically through the prepressing screw rod. After the utility model operates reposefully, the clutch is closed, high-speed high-frequency large amplitude test can be carried out. The utility model has the advantages of good equilibrium, adjustable speed and time counting.
Description
(1) technical field:
The utility model relates to a kind of metallic machine part and detects test unit, particularly a kind of novel spring fast pressing test machine.
(2) background technology:
At present to being used at a high speed, high-frequency, large amplitude, the spiral compression spring of high load working condition (hereinafter to be referred as spring) imposes the device of high speed compression test, it generally all is the homemade special test equipment of each user, and be to be horizontal mostly, directly open pressing spring with direct motor drive crank or cam rotating mechanism, the version of single speed running test, there is not counting on the machine, time set, can only detect a spring at every turn, there are not the accumulation of energy balanced controls yet, the starting current of motor is big, start difficulty, vibration is big during work, the noise height, test mode is lack of standardization, timing, count inaccurate, the difficult repeated authentication of test findings.And horizontal type structure, very easily loss spring and spring location core bar.
(3) utility model content:
Here can be the public provide a kind of startup easily, operation balance safety, test speed, frequency adjustable, the timing counting accurately, the reliable novel spring fast pressing test of testing result machine.
This novel spring fast pressing test machine is made up of with being fitted on the frame motor, crank rotating mechanism and spring testing jig, different is that used main motor is a varying-speed motor, the bearing spider of varying-speed motor and final drive shaft with axial line parallel, horizontal and together is fitted on the frame; Be connected in aggregatesly with the main pulley of varying-speed motor belt pulley interlock and the drive end of energy-storing flywheel and clutch coupling are coaxial, be sleeved on the final drive shaft, the driven end and the final drive shaft of clutch coupling install.Eccentric wheel on the two cover crank rotating mechanisms is on the same plane of the axial line of crossing final drive shaft with the excentric shaft on the eccentric wheel two ends that are fitted in final drive shaft respectively oppositely is set, two perpendicular respectively positions, side, two ends that are contained in final drive shaft on the frame of spring testing jig, the end of the crank of crank rotating mechanism cuts with scissors dress mutually with stage clip slide block in the setting slide rail that is fitted in the spring testing jig, the spring prepressing device all is being set on two spring testing jigs separately, the axial line of the precompressed screw mandrel that is equipped with pre-wedge on the spring prepressing device parallels with the setting slide rail, spring supporting seat on the pre-wedge be positioned at the stage clip slide block pressure spring head under, timing, counter and final drive shaft link.
When this novel testing machine started, the load of varying-speed motor had only energy-storing flywheel, so starting current is very little.Earlier two tested springs are installed respectively on the spring testing jig before the start, utilize the pressure spring head cramping of spring supporting seat on the pre-wedge and stage clip slide block to live the both ends of the surface of tested spring, and make two pre-wedges apply precompressed synchronously to the tested spring on the double by the precompressed screw mandrel, guarantee that the precompressed length of two tested springs is accurate, consistent; Start varying-speed motor, after the rotating speed of varying-speed motor reached setting value and running steadily, the clutch coupling that closes again began test.Close behind the clutch coupling, the kinetic energy that varying-speed motor and energy-storing flywheel discharge promptly drives final drive shaft and the running of crank rotating mechanism, and the stage clip slide block on the crank while driving spring testing jig begins the tested spring on two stations is carried out fast pressing test.Because the eccentric excentric shaft on the two crank rotating mechanisms is reversing device, stage clip slide block on the two spring testing jigs promptly is counter motion, so reached good equilibrium state in the time of can making complete machine work, so this novel spring fast pressing test machine can carry out high speed, high-frequency, large amplitude test, and vibrate little, noise is low.
