Description
Technical field
The utility model relates to a kind of drop machine.
Background technology
The Package Testing technology is as the performance test of research wrappage, packing container and package and the science and technology of analysis, especially in the transportation and packing system design, need be to Static Compression characteristic, dynamic buffering characteristic, creep and recovery characteristic, the vibration transmissibility of padded coaming or structure, the packing container load-bearing capacity, and test analysis is carried out in resistance to compression of package, shock resistance, anti-vibration performance etc.The purpose of Package Testing is in order to evaluate the fine or not degree and the result of packing.
As an extremely important test---the free fall test of Package Testing, its objective is that the examination product provides improved suggestion and foundation to the adaptability of dropping shock environment and for the package design of product in the transportation process of circulation.Drop machine is exactly to be exclusively used in the damage situations of testing package product when falling, generally all comprehensive fall-down test is carried out at face, rib, the angle of package, but, these drop machines are to the rib of package, angle fall-down test the time, can only rely on the artificial visually examine that the attitude of package is adjusted, not corresponding device for adjusting posture automatically, therefore the precision of test is subjected to artificial interference.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of attitude-adjusting system of drop machine, and this mechanism can adjust the attitude that will carry out the package of fall-down test.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of attitude-adjusting system of drop machine, be arranged on the lifter of drop machine, comprise the anchor clamps that are used to place package, also comprise base, two stepper motors, swinging block, pole and double-crank, base is fixedly on the lifter, a stepper motor is installed on base, the output shaft of this stepper motor is connected with an end vertical fixing of double-crank, the other end of double-crank connects the body of another stepper motor, the output shaft of this stepper motor and pole axially are being fixedly connected, pole is passed swinging block and is rotatably connected with swinging block, swinging block and base are rotatably connected, and anchor clamps are fixedly connected on the other end of pole.
The link of pole and anchor clamps has fan groove, and anchor clamps have the folding rib, and the folding rib of these anchor clamps drops in the fan groove of pole and welds together.
Pole is provided with two axle collars in the junction with swinging block, swinging block is the combination of two semicircle intermediate plates and is stuck between two axle collars.
Be connected by shaft coupling between the output terminal of stepper motor and the double-crank, be connected by shaft coupling between the output terminal of another stepper motor and the pole.
The beneficial effects of the utility model are, thereby it can adjust the attitude of the position adjustment package of anchor clamps by the rotational angle of control step motor.Two stepper motors in the utility model are controlled the swing and the rotation of pole respectively by double-crank mechanism and swinging block, adjust the two-freedom of anchor clamps, have realized the attitude adjustment of package.Use the utility model, can accurately adjust required angle, make the gravity vertical of test specimen accurately pass through its rib, angle, the accuracy of warranty test, device structure is simple, easy to operate simultaneously.
