Detailed Description

As shown in fig. 1-6, the reciprocating impact device 2 comprises a support 2-1, a driving motor 2-2, a rotating shaft 2-3, a first cam 2-4, a second cam 2-5, a swing arm 2-6, a swing arm connecting shaft 2-7, rollers 2-8, a tension spring 2-9, a striking rod 2-10, a connecting rod 2-11, a chain and sprocket transmission mechanism 2-12 and a tension spring connecting frame 2-13, wherein the driving motor 2-2 is fixedly arranged on the support 2-1, the rotating shaft 2-3 is rotatably connected with the support 2-1 through two bearings, an output shaft of the driving motor 2-2 is connected with one end of the rotating shaft 2-3 through the chain and sprocket transmission mechanism 2-12 (the output shaft of the driving motor 2-2 can also be connected with the rotating shaft 2-3 through other known transmission mechanisms), the first cam 2-4 and the second cam 2-5 are fixedly connected with the rotating shaft 2-3 (can be fixed in a welding mode), the swing arm connecting shaft 2-7 is fixedly connected with two sides of the support 2-1, the lower end of the swing arm 2-6 is rotatably connected with the swing arm connecting shaft 2-7 (specifically, the lower end of the swing arm can be realized through a bearing or the swing arm connecting shaft penetrates through a circular hole at the lower end of the swing arm), the roller 2-8 is rotatably connected with the upper end of the swing arm 2-6, and the extension spring connecting frame 2-13 is fixedly connected with two sides of the support; one end of an extension spring 2-9 is connected with an extension spring connecting frame 2-13, the other end of the extension spring is connected with a swing arm 2-6, a connecting rod 2-11 is fixedly connected with the lower end of the swing arm 2-6 (particularly in a welding mode or a screw connection mode), and a striking rod 2-10 is fixedly connected with the connecting rod 2-11 (particularly in a welding mode or a screw connection mode); the first cam 2-4 is provided with an arc-shaped jacking part 2-4-1 and a straight line part 2-4-2; the second cam 2-5 has the same structure as the first cam 2-4, and it is preferable to provide two cams, and it is also possible to provide one cam, or 3 cams, 4 cams, or more. When the rotating shaft 2-3 is driven by the driving motor 2-2 to rotate, the first cam 2-4 and the second cam 2-5 are driven to rotate (anticlockwise in the figure 1), the arc-shaped pressing part 2-4-1 of the first cam 2-4 can be used for pressing the roller 2-8 rightwards, so that the swinging arm 2-6 swings at a certain angle rightwards by taking the swinging arm connecting shaft 2-7 as an axis, meanwhile, the tension spring 2-9 is stretched to store energy, the support 2-1 is fixedly arranged on the platform 5 in a state shown in the figure 1, and the striking rod 2-10 is far away from the platform 5 under the driving of the swinging arm 2-6 and the connecting rod 2-11; when the rotating shaft 2-3 further continues to rotate, the roller 2-8 is contacted with the combination point of the arc-shaped pressing part 2-4-1 and the straight part 2-4-2 of the first cam 2-4, the first cam 2-4 is disengaged (the first cam 2-4 no longer acts on the swing arm 2-6, as shown in fig. 4), the swing arm 2-6 is immediately rotated in the opposite direction by a certain angle under the pulling force of the tension spring 2-9, so as to drive the striking rod 2-10 to move downwards (towards the platform 5, as shown in fig. 5), and then the beating rods 2-10 beat the object 4, the first cam 2-4 and the second cam 2-5 do work circularly, and then the beating rods 2-10 rapidly reciprocate up and down to beat the object 4 placed on the platform 5. The position of the extension spring 2-9 is changed or the tension of the spring is changed by selecting springs with different specifications and models, so that the output impact force of the striking rod 2-10 can be adjusted.

It should be noted that the striking rod 2-10 is only one specific implementation form as the striking component, and is not limited thereto, and the striking rod 2-10 may be replaced by a striking hammer 2-14 as shown in fig. 6, a connecting rod 2-15 is fixedly connected to the lower end of the swing arm 2-6, and the striking hammer 2-14 is fixedly connected to the connecting rod 2-15. By adopting the structure of the striking hammer, the striking hammer has larger mass, so the gravity of the striking hammer can also increase the striking force.

As shown in FIG. 7, another specific structure of the striking component is that the striking plate connecting arms 2-17 are fixedly connected with the lower ends of the swing arms 2-6, the striking plates 2-16 are fixedly connected with the striking plate connecting arms 2-17, and the striking plates 2-16 can be rectangular, circular and the like. It should be noted that the mass of the striking plates 2-16 and the striking plate connecting arms 2-17 can be designed to be relatively large, striking force is applied downwards by the gravity of the striking plates 2-16 and the striking plate connecting arms 2-17, and the extension springs 2-9 are not needed; on the basis of the structure, as shown in fig. 8, a buffer spring 2-18 can be connected between the top of the bracket 2-1 and the striking plate connecting arm 2-17, and when the striking plate 2-16 moves downwards, the buffer spring 2-18 provides upward pulling force, so that the striking force is adjusted.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, as various modifications and variations will be apparent to those skilled in the art.
