Description

A kind of small-sized landing impact testing machine automatically send pick-off unit

Technical field

The utility model relates to testing machine technical field, and what specifically relate to a kind of small-sized landing impact testing machine send pick-off unit automatically.

Background technology

Drop hammer impact testing machine, by drop hammer lifting is arrived to certain altitude, is then discharged, and does freely falling body potential energy is converted into impact kinetic energy impact specimen.And use with regard to computer acquisition and analyze impulse test test findings.Impact testing machine is produced and is paid attention in various countries at present, the impact testing machine producing states such as Japan, the U.S. is very advanced, especially in Japan, the QZW series drop hammer impact testing machine of Jitian's essence machine strain research and development, the FAG series drop hammer impact testing machine of her rattan essence machine research and development; In the U.S., the impact testing machine of the SM model that AVCO company manufactures, the impact testing machine of 886 models that MTS company manufactures.Thereby China is urgent need to research and develop advanced impact testing machine, to reach and to catch up with external advanced person's impulse test machine technology, tool is of great significance.

At present, its major defect is: manual operation labour intensity is large, inefficiency, and feeding speed does not all reach the requirement of concerned countries standard; The location of sample is inaccurate, affects experimental measurement precision; Landing impact testing machine drop impact energy is large, the sample movement that is hit, and operator's personal safety can not get reliable guarantee, dangerous high.

In order to overcome above-mentioned technical matters, what the utility model provided a kind of small-sized landing impact testing machine send pick-off unit automatically, and the technical scheme of employing is as follows:

Small-sized landing impact testing machine automatically send a pick-off unit, it is characterized in that, comprise mobile shock testing machine, guide rail anvil block, front-end bearing pedestal, servomotor, ball-screw, cylinder, test specimen, rear bearing block, tailstock and grade slab; Described guide rail anvil block is arranged on described grade slab; Described front-end bearing pedestal and rear bearing block are arranged on described grade slab; Described ball-screw one end is arranged on described front-end bearing pedestal, and the other end is arranged on described rear bearing block; Described motor is arranged on the boss of described front-end bearing pedestal, and the motor shaft of described motor is connected with one end of described ball-screw; Described mobile shock testing machine is arranged on described guide rail anvil block, and its lower end is fixedly connected with the travelling nut of described ball-screw; Described tailstock is arranged on one end of described mobile shock testing machine, and described cylinder is arranged on the other end of described mobile shock testing machine.

The beneficial effects of the utility model are: product structure is simple, novel unique, automatically the feeding of test specimen, automatically location, with test after taking-up, for workpeople provides convenience, reduced labour intensity widely, improved test efficiency.

In figure: 1 moves shock testing machine, 2 guide rail anvil blocks, 3 front-end bearing pedestals, 4 servomotors, 5 ball-screws, 6 cylinders, 7 test specimens, 8 rear bearing blocks, 9 tailstocks and grade slab 10.

Embodiment

With reference to Figure of description 1 to accompanying drawing 3, the pick-off unit that automatically send of a kind of small-sized landing impact testing machine of the present utility model is described in detail below.

Small-sized landing impact testing machine automatically send a pick-off unit, it is characterized in that, comprise mobile shock testing machine 1, guide rail anvil block 2, front-end bearing pedestal 3, servomotor 4, ball-screw 5, cylinder 6, test specimen 7, rear bearing block 8, tailstock 9 and grade slab 10; Described guide rail anvil block 1 is arranged on described grade slab 10; Described front-end bearing pedestal 3 and rear bearing block 8 are arranged on described grade slab 10; Described ball-screw 5 one end are arranged on described front-end bearing pedestal 3, and the other end is arranged on described rear bearing block 8; Described motor 4 is arranged on the boss of described front-end bearing pedestal 3, and the motor shaft of described motor 3 is connected with one end of described ball-screw 5; Described mobile shock testing machine 1 is arranged on described guide rail anvil block 2, its lower end and the travelling nut of described ball-screw 5 are fixedly connected with described tailstock 9 and are arranged on one end of described mobile shock testing machine 1, and described cylinder 6 is arranged on the other end of described mobile shock testing machine 1.

Whole device is as for the below of landing impact testing machine, when test, test specimen 7 is placed on mobile shock testing machine 1, is fixed by cylinder 6 and tailstock 9, then control servomotor 4, drive ball-screw 5, thereby promote mobile shock testing machine 1, test specimen 7 is delivered to the testing position of setting, after impulse test completes, again control servomotor 4, release mobile shock testing machine 1, take out test specimen 7.

The above, be only embodiment of the present utility model, and in the scope that those of ordinary skill in the art disclose at the utility model, the variation that can expect easily, within all should being encompassed in the protection domain of utility model.
