Description

Technical Field

[0001] This application relates to the field of laser processing auxiliary equipment technology, and in particular to a workpiece clamping device for laser cladding. Background Technology

[0002] Laser cladding technology can form a high-performance coating that is metallurgically bonded to the base metal on the surface of metal workpieces. It is used to strengthen the surface of vulnerable parts such as gears and bearings in the field of mechanical manufacturing. In laser cladding, the stability of workpiece clamping is the key prerequisite for determining the cladding quality. During laser cladding, the depth of the molten pool formed by the high-energy laser beam acting on the workpiece surface is only 0.1-2mm. It is also necessary to keep the alloy powder accurately fed into the molten pool. If the clamping is unstable and causes a slight displacement of the workpiece, it will cause the laser beam to be misaligned with the cladding area, resulting in local incomplete melting and coating thickness deviation.

[0003] Current workpiece clamping devices have limitations in adjusting the height of the workpiece after it is clamped and fixed, making it difficult to ensure that the workpiece is accurately aligned with the laser cladding area. This is especially true for workpieces with complex curved surfaces, which can easily lead to cladding deviations and affect the cladding quality. To address these issues, we propose a workpiece clamping device for laser cladding. Utility Model Content

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 In this utility model, a workpiece clamping device for laser cladding includes a base 1. A set of support legs 6 are fixedly connected to the upper surface of the base 1, which can form a stable support for the base 1. A support plate 2 is provided above the base 1. A carrier plate 3 is rotatably connected to the upper surface of the support plate 2 through a column 9. A clamping assembly 4 is provided on the outside of the carrier plate 3. The clamping assembly 4 includes a set of mounting frames 401 fixedly connected to the outer surface of the carrier plate 3. An electric push rod 402 is installed on the bottom surface of the top of each mounting frame 401. An arc plate 403 is installed on the telescopic end of each electric push rod 402. When the workpiece is above the carrier plate 3, the electric push rod 402 can be activated to extend, and the electric push rod 402 will push the arc plate 403 to move, and the arc plate 403 will clamp and fix the workpiece.

[0022] A height adjustment assembly 5 is provided between the base 1 and the support plate 2. The height adjustment assembly 5 includes a motor 501 mounted on the upper surface of the base 1. A threaded rod 502 is fixedly connected to the output end of the motor 501. A movable plate 503 is threadedly connected to the outer surface of the threaded rod 502. Top plates 504 are fixedly connected to both the front and rear ends of the movable plate 503. A set of deflection plates 505 are hinged to the upper surface of each top plate 504. The top end of each deflection plate 505 is hinged to the bottom surface of the support plate 2. The motor 501 is controlled to drive the threaded rod 502 to rotate. The movable plate 503 will move on the threaded rod 502, and the top plate 504 will move at the same time. The deflection plate 505 on the top plate 504 will gradually deflect to a vertical state and gradually lift the support plate 2, thereby completing the adjustment of the workpiece height. This can effectively avoid deviation in cladding and ensure the quality of cladding. A set of guide frames 506 are slidably connected to the outer surface of each top plate 504. The bottom end of each guide frame 506 is connected to the upper surface of the base 1. The guide frames 506 can stabilize the top plate 504, thereby ensuring the smooth movement of the top plate 504.

[0023] A set of positioning plates 7 are slidably connected to the upper surface of the base 1. The top of each positioning plate 7 is connected to the bottom surface of the support plate 2. The bottom of each positioning plate 7 is fixedly connected to a limiting plate 8. The positioning plates 7 can stabilize the movement of the support plate 2 and further ensure its smooth lifting. The limiting plates 8 can restrict the upward movement of the positioning plates 7 and further prevent the positioning plates 7 from separating from the base 1.

[0024] A set of circularly arranged arc-shaped frames 10 are fixedly connected to the upper surface of the support plate 2. Each arc-shaped frame 10 has a connecting rod 11 slidably connected to its inner wall. The top of each connecting rod 11 is connected to the bottom surface of the carrier plate 3. When the workpiece angle is adjusted, the carrier plate 3 only needs to be pulled to deflect. At the same time, the connecting rod 11 will slide inside the arc-shaped frame 10.

[0025] The working principle of this application is as follows: When in use, the workpiece is placed on the carrier plate 3, and then the electric push rod 402 is extended. The arc plate 403 will then descend to hold the workpiece. When the height of the workpiece needs to be adjusted, the motor 501 is controlled to work. The motor 501 will drive the threaded rod 502 to rotate, and the moving plate 503 will move on the threaded rod 502. At the same time, the top plate 504 will move, and the deflection plate 505 on the top plate 504 will gradually deflect to a vertical state and gradually lift the support plate 2, thereby completing the adjustment of the workpiece height. When the angle of the workpiece needs to be adjusted, simply pull the carrier plate 3 to deflect it. At the same time, the connecting rod 11 will slide inside the arc frame 10, which can effectively avoid deviation in cladding and thus ensure the cladding quality.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
