Description

Technical Field

[0001] The present invention relates to the technical field of additive manufacturing, and in particular to a lens translation structure for laser additive manufacturing. Background Art

[0002] Additive manufacturing technology is a technology that uses a method of gradually accumulating materials to manufacture solid parts. Compared with traditional material removal-cutting processing technology, it is a "bottom-up" manufacturing method; the existing document with announcement number CN221701644U discloses a lens translation structure for laser additive manufacturing; its solution includes a material delivery head, a laser head installed on the side of the material delivery head, a laser head translation mechanism connected to the side of the material delivery head, and the laser head translation mechanism includes a translation adjustment plate and a translation adjustment block, the translation adjustment plate is connected to the material delivery head, and the laser head is connected to the translation adjustment block. The translation adjustment block is connected, and the translation adjustment block can be translated relative to the translation adjustment plate; the translation adjustment plate is provided with a moving slide groove, and the laser head translation mechanism also includes a locking slider and a locking screw, the locking slider is arranged on the upper part of the moving slide groove, and the locking screw passes through the locking slider and the moving slide groove and is connected to the translation adjustment block; the lens translation structure used in the solution for laser additive manufacturing is connected between the material delivery head and the laser head through the laser head translation mechanism, and can translate the laser head within a certain range to change its incident position or incident angle to meet the melting requirements of different additive materials.

[0003] The above solution connects the material conveying head and the laser head by setting a translation structure, and adjusts the incident angle or incident position by controlling the position of the laser head by translation. In order to avoid the influence of the incident angle of the laser head on the processing, the existing additive manufacturing devices all adopt an integrated setting of the material conveying head and the laser head, and the material conveying head is evenly set on the side of the laser jet port. In existing additive manufacturing work, for example, for the processing of pipe fittings, the pipe fittings are generally fixed on the rotating chuck of the lathe, and then the additive mechanism is controlled by the robot arm for processing. The main body of the robot arm is fixedly connected to the additive mechanism, and a rotating seat is set at the bottom of the robot arm to improve its working flexibility. ; Most of this process involves the rotating chuck driving the pipe to rotate, and the additive mechanism spraying additives on the side walls of the pipe; when it is necessary to perform axial additives on the pipe, for example, cracks in the axial direction of the outer wall of the pipe need to be repaired by additives; or when it is necessary to perform axial additive processing on the intact side wall of the pipe; the existing solution is generally to continue to drive the pipe to rotate by rotating the chuck, and the robotic arm controls the additive mechanism to reach the appropriate position for processing until it reaches the specified position; this process not only affects the processing efficiency, but also causes a certain amount of waste of materials; the connection between the existing robotic arm and the additive mechanism lacks corresponding stable translation components to meet its actual processing needs.
