The drop test machine is specially used to test the damage of the packaged product when it is dropped. Generally, a comprehensive drop test is performed on the surface, edges, and corners of the package. , can only rely on manual visual inspection to adjust the attitude of the package, there is no corresponding automatic attitude adjustment device, so the accuracy of the test is interfered by human beings.

Contents of the invention

The technical problem to be solved by the utility model is to provide a posture adjustment mechanism of a drop test machine, which can adjust the posture of the package to be subjected to a drop test.

In order to solve the above-mentioned technical problems, the technical solution of the present invention is: a posture adjustment mechanism of a drop test machine, which is set on the lift of the drop test machine, including a clamp for placing packages, a base, two steppers Motor, rocker, pole and double crank, the base is fixed on the elevator, a stepper motor is installed on the base, the output shaft of the stepper motor is vertically fixedly connected to one end of the double crank, and the other end of the double crank is connected to the other The body of the stepping motor, the output shaft of the stepping motor is fixedly connected to the support rod in the axial direction, the support rod passes through the rocker and is rotatably connected to the rocker, the rocker is rotatably connected to the base, and the fixture is fixedly connected to the support on the other end of the rod.

A fan-shaped groove is formed at the connecting end of the support rod and the clamp, and the clamp has a folded edge, and the folded edge of the clamp falls into the fan-shaped groove of the support rod and is welded together.

The pole is provided with two collars at the connection with the rocker, and the rocker is a combination of two semicircular clips and is stuck between the two collars.

The output end of the stepping motor is connected with the double crank through a coupling, and the output end of the other stepping motor is connected with the strut through a coupling.

The beneficial effect of the utility model is that it can adjust the position of the clamp by controlling the rotation angle of the stepping motor so as to adjust the posture of the package. The two stepping motors in the utility model respectively control the swing and rotation of the pole through the double crank mechanism and the rocker, adjust the two degrees of freedom of the clamp, and realize the attitude adjustment of the package. By applying the utility model, the required angle can be precisely adjusted, so that the gravity line of the test piece can accurately pass through its edges and corners, so as to ensure the accuracy of the test. At the same time, the device has a simple structure and is easy to operate.

Detailed ways

As shown in the figure, the utility model is a posture adjustment mechanism on a drop test machine, which is set on the lift of the drop test machine. The mechanism includes a clamp 1 for placing packages, a base 9, a stepping motor 4, a Enter motor 7, rocker 3, pole 2 and double crank 6, base 9 is fixed on the elevator, a stepper motor 4 is installed on base 9, the output shaft of this stepper motor 4 and an end of double crank 6 pass through a The shaft coupling 5 is connected, and the connecting crank 6 is vertically arranged with the output shaft of the stepping motor 4 . The other end of the double crank 6 is connected to the body of another stepping motor 7, the output shaft of the stepping motor 7 is connected to the strut 2 through a coupling 8 in the axial direction, and the strut 2 passes through the rocker 3 and is connected to the rocker. The block 3 is rotatably connected, the rocker 3 is rotatably connected to the base 9 , and the clamp 1 is fixedly connected to the other end of the pole 2 .

One end of the pole 2 has a fan-shaped groove 10, and the clamp 1 has a folding edge 13, and the folding edge 13 of the clamp falls into the fan-shaped groove 10 of the pole and is welded together.

The pole 2 is provided with two collars 11 at the connection with the rocker 3 , and the rocker 3 is a combination of two semicircular clips and is clamped between the two collars 11 . In this way, the pole 2 can only rotate around its axis in the rocker 3 and cannot slide axially.

In the utility model, the stepper motor 7 is connected with the pole, the rotation of the stepper motor 7 can control the adjustment of the degree of freedom 1 of the fixture, the stepper motor 4 is connected with one end of the double crank mechanism, and the other end of the double crank mechanism is connected with the stepper.
