Further, described hoisting device comprises suspension bracket, hydraulic cylinder, slide block, litter, and described hydraulic cylinder is installed in described suspension bracket top, and the axle head of described hydraulic cylinder and described slide block are hinged, described litter and described slide block be connected to form moving sets, realize the crawl of dropping hammer and release.
Further, described in have the hole of placing counterweight counterweight on dropping hammer, can place counterweight and to dropping hammer, carry out counterweight, realize the demand to different weight of impact.The described two ends of dropping hammer coordinate with described guide rod, slide dropping hammer described in dropping process along described guide rod, guarantee that the running orbit that drops hammer vertically downward.
Further, described piece fixture locating device is comprised of piece fixture, thrust hydraulic cylinder, T-shaped, and described thrust hydraulic cylinder is arranged on base; One end of described piece fixture is flexibly connected with the output shaft end of described thrust hydraulic cylinder; The other end of described piece fixture is flexibly connected with T-shaped; Described thrust hydraulic cylinder drives described piece fixture up and down; Described piece fixture can move by T-shaped in the T-shaped groove being arranged on described base, and described thrust hydraulic cylinder makes piece fixture present different angles of inclination by stroke and backhaul, and the slant range of angle is at 0 °～90 °.
Further, described piece fixture is arranged on the base of frame; Two force cells are housed on described piece fixture, gather in impact process perpendicular to piece fixture direction and be parallel to the power of piece fixture direction, and by Computer display out.
The test method of a kind of drop hammer type multi-angle impact tester of the utility model is: before impulse test, first test specimen is fixed on piece fixture; On one end of thrust hydraulic cylinder stroke drive piece fixture, rise, the other end slides in the T-shaped groove of base, thereby adjusts the angle of inclination of piece fixture; Drop hammer and rise to the needed height of test by suspension bracket; Now hydraulic cylinder stroke band movable slider moves on litter, forces litter to tilt to horizontal direction, and during to certain angle, dropping hammer can be automatically-unhooked, along the guide rod shock-testing test specimen that lands vertically downward; After completing one-shot, two motor reversions, drive suspension bracket to move downward by leading screw, after arriving the position of appointment, hydraulic cylinder backhaul drives litter to move to vertical direction, now just can hang to get and drop hammer, motor forward drives suspension bracket to rise, and drops hammer and gets back to original shock height; Impacting moment, piece fixture can bear very large impulsive force, during heeling condition, can guarantee that angle of inclination is constant by thrust hydraulic cylinder; Sensor measurement is perpendicular to piece fixture direction and be parallel to the stressing conditions of piece fixture direction, and by Computer display out.
A kind of landing impact testing machine design of the utility model has been used new dropping hammer to hang and has been got hoisting way, utilize leading screw to drive and can, so that the height dropping hammer is more accurate, conveniently obtain impact velocity more accurately.It is adjustable that piece fixture has been designed to angle, met real central demand of impacting for different angles.
