Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

A reset mechanism for ball impact resistance tests is shown in figures 1-3 and comprises a material channel 31, a lifting plate 32, a lifting mechanism 33, a material blocking mechanism 34 and a sensor, wherein the material channel 31 is obliquely arranged, the lifting plate 32 is arranged at the lower end of the material channel and is connected with the lifting mechanism 33, the lifting mechanism 33 is used for driving the lifting plate 32 to vertically move, the material blocking mechanism 34 is arranged at one end of the lifting plate 32 to block balls from sliding off, the sensor is arranged at one end of the lifting plate 32, and the sensor can be a photoelectric sensor. The presence of a ball on the lift plate 32 is sensed by a sensor. During normal test, the ball is projected from the launching mechanism 3 to the rebounding plate 2, rebounding balls are obliquely upwards through the rebounding plate 2, impact of the balls is absorbed through the buffer mechanism 5 to enable the balls to fall onto the material guide plate 1, the balls are guided to the launching mechanism 3 through the material guide plate 1, and in the process, the balls cannot fall into the material channel 31 below. However, in the testing process, if the impact height is not enough, the ball will fall under the rebound board 2, slide down along the material channel 31 onto the lifting board 32, and be blocked by the blocking mechanism 34, so that the ball is still on the lifting board 32. Then, the lifting plate 32 is driven by the lifting mechanism 33 to ascend to the material guide plate 1, and the material blocking mechanism 34 is opened, so that the balls are drawn into the launching mechanism 3 along the material guide plate 1. The ball is automatically reset and enters a test state, so that the ball does not need to be watched by a tester, and the labor is saved.

In one embodiment, as shown in fig. 1-6, the striker mechanism 34 includes a cushioned pneumatic rod. FIG. 4 illustrates the position of the reset mechanism prior to actuation; when the lifting plate 32 is lifted, the upper end of the buffer pneumatic rod is propped against the material guide plate 1, and the state shown in fig. 5 is reached; the piston rod of the buffer pneumatic rod is compressed, and when the lifting plate 32 moves to be equal to the height of the material guide plate 1, the ball falls into the launching mechanism 3 along the material guide plate 1, and the state shown in fig. 6 is achieved.

In one embodiment, as shown in FIGS. 1-3, the lift mechanism 33 comprises a rodless cylinder. Preferably, a guide rod is further included, and the guide rod is disposed opposite to the rodless cylinder, so that the lifting plate 32 stably moves up and down.

In another embodiment, as shown in fig. 1-3 and 7, the material stopping mechanism 34 includes a cylinder 341 and a rod 342, the rod 342 is cylindrical, and the cylinder 341 drives the rod 342 to reciprocate up and down. The stop bar 342 is cylindrical to reduce the ball impact area with the stop bar 222 to reduce the ball bounce.

In one embodiment, as shown in fig. 1-3, the material channel 31 includes a material guiding rod 311 and a supporting frame 312, the supporting frame 312 is recessed with an arc-shaped recess, and the material guiding rods 311 are spaced in the recess. In the utility model, the material guiding rods 311 are four, and the material guiding rods are arranged in the notches at equal intervals to form a guide groove for guiding the sliding of the ball. Similarly, the rebound range of the ball is reduced by reducing the impact contact area of the ball with the material channel 31.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
