Description

Technical Field

[0001] This utility model relates to the field of shot peening, and in particular to a servo-adjustable dual-gun shot peening mechanism. Background Technology

[0002] Shot peening is a surface strengthening process that uses high-speed shot to impact the surface of a workpiece, forming a compressive stress layer. This process is widely used in various fields. Modern shot peening systems typically employ robotic automation, combined with intelligent control systems to achieve precise control of process parameters and shot trajectory planning, ensuring consistent and reliable processing results. In existing automated shot peening processes, a single spray gun is usually used to peen the workpiece, resulting in low peening efficiency. Therefore, existing technology requires a new spray gun structure to improve shot peening efficiency. Utility Model Content

[0021] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0023] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides a servo-adjustable dual-gun shot peening mechanism, which includes a connecting plate 1, a fixed-end shot peening gun 2, and a swing-end shot peening gun 3. The fixed-end shot peening gun 2 is fixedly mounted on the connecting plate 1, and the swing-end shot peening gun 3 is rotatably mounted on the connecting plate 1. The fixed-end shot peening gun 2 and the swing-end shot peening gun 3 are used to shot peen the workpiece.

[0026] In this invention, by setting a fixed-end spray gun 2 and a swing-end spray gun 3 on the connecting plate 1, two spray guns can be used simultaneously for shot peening, greatly improving the shot peening efficiency. Furthermore, rotating the swing-end spray gun 3 adjusts the center distance and angle between the two fixed-end spray guns 2 and the swing-end spray gun 3 to adapt to different workpieces, resulting in greater applicability.

[0027] Furthermore, the connecting plate 1 is provided with a fixed arm 11 and a swing arm 12. One end of the fixed arm 11 is fixedly mounted on the connecting plate 1, and the other end of the fixed arm 11 is fixedly connected to the fixed end spray gun 2. One end of the swing arm 12 is hinged to the connecting plate 1, and the other end of the swing arm 12 is fixedly connected to the swing end spray gun 3.

[0028] In a preferred embodiment, a geared motor 13 is provided on the connecting plate 1. The output shaft of the geared motor 13 is connected to the swing arm 12. The output shaft of the geared motor 13 rotates relative to the connecting plate 1 through a bearing. The geared motor 13 drives the swing arm 12 to rotate. By using the geared motor 13 to drive the swing arm 12 to rotate, the rotation control of the swing-end spray gun 3 is achieved.

[0029] Furthermore, an elastic element 14 is provided between the swing arm 12 and the connecting plate 1 to eliminate bearing clearance in the bearing on the output shaft of the geared motor 13. The elastic element 14 is a spring, which acts as an adjustment mechanism to compensate for gear wear in the reducer and eliminate clearance. The swing end spray gun 3 can abut against the fixed end spray gun 2 under the action of the spring force.

[0030] In a preferred embodiment, both the fixed-end spray gun 2 and the swing-end spray gun 3 are connected to the shot peening pipeline. The shot peening pipeline is directly connected from the top of the safety chamber to the tail ends of the fixed-end spray gun 2 and the swing-end spray gun 3, avoiding friction with the robot body and increasing its service life.

[0031] Finally, the dual-gun shot peening mechanism also includes a robotic arm, the end of which is fixedly connected to a connecting plate 1. The connecting plate 1 has fixing holes for connecting the robotic arm. The connecting plate 1 is detachably connected to the robotic arm via fasteners passing through the fixing holes.

[0032] It should be understood that the above description of the specific embodiments of this utility model is only for illustrating the technical route and features of this utility model, and its purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. However, this utility model is not limited to the specific embodiments described above. All changes or modifications made within the scope of the claims of this utility model should be covered by the protection scope of this utility model.
