Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1, an acceleration impact tester includes a machine table 10, a screw rod 11 is disposed above the machine table 10, a lower end of the screw rod 11 is rotatably connected to the machine table 10, a grabbing mechanism 12 is disposed on the screw rod 11, the grabbing mechanism 12 is in threaded connection with the screw rod 11, and an impact object 20 is grabbed and fixed by the grabbing mechanism 12.
An impact felt seat 13 is arranged above the machine table 10, the impact felt seat 13 is correspondingly arranged below the grabbing mechanism 12, the lower end of the screw rod 11 is fixed on a first bevel gear 14, a rotating rod 15 is arranged on one side of the machine table 10, the rotating rod 15 is rotatably connected with the machine table 10, a second bevel gear 16 is arranged at one end of the rotating rod 15, and the second bevel gear 16 and the first bevel gear 14 are meshed with each other.
One end of the rotating rod 15, which is far away from the second bevel gear 16, is provided with a handle 17, the handle 17 is fixedly connected with the rotating rod 15, and people can drive the rotating rod 15 to rotate through the handle 17. It is also possible to provide a rotating motor at the end of the rotating rod 15 away from the second bevel gear 16, and to rotate the rotating rod 15 in a mechanically controlled manner.
The method comprises the steps of placing an object to be detected on an impact felt seat 13 on a machine table 10, correspondingly arranging a grabbing mechanism 12 above the impact felt seat 13, continuously grabbing and fixing the impact object 20 through the grabbing mechanism 12, enabling the impact object 20 to freely fall through opening of the grabbing mechanism 12 to collide with the object to be detected on the impact felt seat 13, and accordingly completing the numerical value detection of the acceleration impact land.
When people need to adjust the height of the impact object, the rotating rod 15 on one side of the machine table 10 is rotated, the second bevel gear 16 at one end of the rotating rod 15 is used for driving the first bevel gear 14 to rotate, the rotation in the vertical direction is converted into the rotation in the horizontal direction, so that the screw rod 11 is driven to rotate, the grabbing mechanism 12 in threaded connection with the screw rod 11 moves up and down along the screw rod 11, and the purpose of adjusting the height of the impact object 20 is achieved.
