The invention is further described below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present invention, and are not intended to limit the scope of the present invention.

Examples:

the embodiment provides a buffer device, which can be used for throwing various workpieces including castings after finishing grinding, so as to improve the workpiece throwing efficiency and reduce the damage defect caused in the workpiece throwing process. As shown in fig. 1, the buffering means comprises two working parts: the support seat and the guide mechanism are used for supporting the guide mechanism, and the height of the support seat can be configured according to the operation scene requirement so as to avoid the situation that the part is lost due to artificial bending. The guiding mechanism can extend from the workpiece throwing area to the workpiece collecting area, a feeding opening is arranged close to the workpiece throwing area, a discharging opening is arranged close to the workpiece collecting area, the workpiece collecting area can be provided with a workpiece containing container 3, and a workpiece can slide from the workpiece throwing area to the workpiece containing container 3 through the guiding mechanism. The guiding mechanism can be arranged on the supporting seat in a downward inclined way, so that the workpiece can slide in the guiding mechanism by utilizing the gravity of the workpiece until the workpiece falls into the workpiece containing container 3.

In order to prevent the workpiece from falling down in the process, the falling speed of the workpiece is too high due to the conversion of potential energy and kinetic energy, and the workpiece is impacted into the workpiece containing container 3 during blanking or the workpiece which is put in is damaged, the flexible buffer mechanism 4 is arranged at the blanking opening to absorb the impact kinetic energy when the workpiece is separated from the blanking opening, so that the damage defect of the workpiece is avoided.

As shown in fig. 1, 2 and 4, in this embodiment, the supporting seat further includes a bottom plate 1-1 and a supporting rod 1-2, one end of the supporting rod 1-2 is supported on the bottom plate 1-1, the other end is connected with the guiding mechanism, during practical application, the weight of the supporting rod 1-2 and the bottom plate 1-1 needs to make the guiding mechanism place steadily, if necessary, the bottom plate 1-1 should be weighted, and according to the practical weight adjustment of the buffer device for carrying articles, and the supporting rod 1-2 and the bottom plate 1-1 should use high-strength bending-resistant materials, so as to avoid bending deformation in the subsequent use process and influence the workpiece throwing precision. The guide mechanism is provided with adjusting holes 5 for adjusting the installation height of the guide mechanism, and the number of the adjusting holes 5 can be set according to the length of the guide mechanism. The arrangement of the adjusting holes 5 not only can meet the requirements of different throwing heights, but also can meet the height requirements of different operators; and the length of the guide mechanism penetrating into the workpiece containing container 3 can be adjusted, so that the height of the workpiece falling into the workpiece containing container 3 is adjusted, and the damage between the workpieces is avoided.

The bottom of the bottom plate 1-1 is provided with a moving device, which can be a plurality of moving pulley blocks, a moving device with the same effect as a crawler belt and the like, or a moving sliding rail arranged between working areas so as to move the buffer device.

As shown in fig. 3, in this embodiment, the guiding mechanism includes a chute 2-1 and a hopper 2-2, where the hopper 2-2 is disposed on the chute 2-1, so that a workpiece can accurately fall onto the chute 2-1. The chute 2-1 is divided into two working sections, wherein the working sections comprise a straight line section and an arc section, the feeding port is arranged at the starting end of the straight line section, the discharging port is arranged at the tail end of the arc section, and the tail end of the straight line section is in smooth transition connection with the starting end of the arc section. The straight line section is provided with the adjusting hole 5, the height of the guide mechanism can be adjusted by utilizing the adjusting hole 5, and the extending length of the guide mechanism from the workpiece throwing area to the workpiece containing container 3 is along the workpiece throwing area, so that the inside of the straight line section is smooth, the falling workpiece is facilitated to slide down, and the falling workpiece turns along a track to be decelerated when sliding to the arc section. If the height difference between the throwing area and the workpiece containing container 3 is large, the arc section can be replaced by a spiral chute. The chute 2-1 is made of high-strength materials, so that bending deformation in the subsequent use process is avoided.

The feeding hopper 2-2 is arranged at the feeding opening, and the guiding function is assisted to the discharging operation, so that the workpiece can accurately fall on the chute 2-1. The shape of the hopper 2-2 can be set according to the specific shape of the workpiece to be moved, so that the workpiece can pass smoothly, for example, if the workpiece is square, the hopper 2-2 can be set as a square channel, and the other cases are vice versa.

In the present embodiment, in order to control the falling speed of the work, a flexible buffer mechanism 4 is provided on the buffer device. The flexible buffer mechanism 4 comprises a buffer rubber attached to the inner wall of the feeding hopper 2-2 and a rubber 4-1 movably connected to the feeding opening. On the one hand, the buffer rubber can avoid hard collision between the workpiece and the feeding hopper during feeding, and on the other hand, the friction force of the buffer rubber acts to reduce the initial speed of the workpiece. As shown in the C-C section view of FIG. 2, the rubber sheet 4-1 is rotatably connected to the feed opening through a rotating shaft 4-2. When the rubber sheet 4-1 is not impacted by the workpiece, the rubber sheet is in a vertical state under the action of gravity; the workpiece falls to the blanking opening, the rubber sheet 4-1 is rotationally connected around the rotating shaft 4-2 under the impact action of the workpiece, and the kinetic energy of the workpiece is converted into the potential energy of the rubber sheet 4-1 during the process, so that the deceleration action is achieved, and the workpiece finally and stably falls into the workpiece containing container 3.
