The test method of the impact test equipment comprises the following steps:
s1 test preparation
In the initial state, as shown in fig. 1, the suspension rope 15 is located on a dashed line L1, and the tension rope 46 between the corresponding third interface 23 and the second guide wheel 43 is also located on the dashed line L, that is, the suspension rope 15 and the tension rope 46 are located on the same straight line. As shown in fig. 1 and 2, according to the pulling force rope 46 pulled by the third interface 23 and the pulling force rope 46 pulled by the gravity ball 47, the gravity ball 47 is at the lowest position, at this time, the pulling force rope 46 between the third interface 23 and the second guide wheel 43 reaches the shortest state, the slider 42 slides along the guide rail 41 to the rightmost R3 position, and as shown in fig. 2, an inductor 48 is disposed outside the R3 position for sensing the position of the slider 42 and outputting a signal.
Referring to fig. 3 and 6, the left end of the connecting shaft 512 is located on the right side of the imaginary line L2 in fig. 3, that is, the second protruding strips 5121 are not inserted between the plurality of first protruding strips 5022, and at this time, the rotation of the reel 502 is not affected by the connecting shaft 512 and is in a free rotation state. The cylinder retraction of the connecting post 508 is controlled such that the connecting post 508 is in the left limit position.
When the reel 502 rotates, as shown in fig. 3, the first protrusion 50211 of the convex ring 5021 on the right rotates and slides in and out between the second protrusions 5101, and the pressing plate 510 slides left and right along the inner wall of the fixed ring 505 under the action of the first protrusion 50211 and the spring 511.
S2 winding
(1) As shown in fig. 3, the connection shaft 512 is rotated by driving the motor, and the connection shaft 512 is rotated along the inner wall of the middle hole 5022 positioned at the right side of L2;
(2) as shown in fig. 3, the cylinder drives the connection post 508 to move rightward, so that the roller 502 moves rightward, and the second protrusion 5121 is inserted between the first protrusions 5022, and the connection shaft 512 drives the roller 502 to rotate under the rotation action of the connection shaft 512.
While the reel 502 moves to the right, the sliding sleeve 509 keeps moving synchronously, as shown in fig. 3, the liner ring 504 on the right pushes the pressing plate 510 and the spring 511 to move synchronously to the right, so as to prevent the overlarge rotation resistance of the connecting shaft 512 caused by overlarge pressure between the pressing plate 510 and the convex ring 5021, thereby reducing the rotation moment of a motor for driving the connecting shaft 512 to rotate and reducing the use cost of motor selection.
As shown in fig. 1, under the rotation action of the rewinding wheel 502, the rewinding wheel 502 winds the winding rope 501, the winding rope 501 lifts the impact block 2 to a position where the suspension point P is close to the first guide wheel 16, at this time, the corresponding third interface 23 lifts the tension rope 46 to the right and upper side, the sliding block 42 slides to the leftmost R1 region along the guide rail 41, and the corresponding inductor 48 senses the position of the sliding block 42 in the R1 position, as shown in fig. 2, and the gravity ball 47 rises to the highest position.
S3 impact Release
The connection column 508 is driven to move to the left by the cylinder as shown in fig. 3, so that the roller 502 moves to the left, so that the second protrusion 5121 is axially separated from the first protrusion 5022, and the roller 502 is not controlled by the rotation of the connection shaft 512. As shown in fig. 1, the impact block 2 swings downward and leftward to impact the test board 3 by the impact block 2 and the gravity ball 47, and the impact block 2 pulls the winding rope 501 downward and leftward, and the corresponding winding rope 501 pulls the winding wheel 502 to rotate.
When the tension rope 46 is continuously pulled to the test board 3 side from the position of the dotted line L2 shown in fig. 1 under the action of swinging the impact block 2 leftwards and downwards, the tension rope 46 is lengthened between the third interface 23 and the second guide wheel 43, the sliding block 42 reaches the position R2 shown in fig. 1 at the moment that the test board 3 is impacted by the impact block 2, at the moment, a signal is transmitted to the PLC system through the sensor 48 at the position R2, and the system controls the action of the air cylinder to perform the winding operation of the step S2.
Since the winding rope 501 is pulled out under the downward dragging action of the impact block 2, even if the damping action of the pressing plate 510 exists, the phenomenon that the winding rope 501 is pulled out too much still occurs, so that when the winding rope 501 is wound, the excessive winding rope 501 is wound, and the winding speed is reduced, therefore, when the impact block 2 falls down in a downward swinging way, the sliding block 42 transmits a signal for starting the driving of the air cylinder to the system through the sensor 48 for the first time, so as to perform winding operation in advance, and prevent the impact block 2 from striking the test board 3, and the impact block 2 strikes the test board 3 again because the winding rope 501 does not form effective control on the impact block 2.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
