[0019] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0020] This utility model provides a clamp for a coaxial powder feeding and repair device. Please refer to [link / reference]. Figure 1-4 As shown, it includes a base 1 for fixed installation on a workbench. The base 1 is provided with a horizontal adjustment mechanism 2 and a vertical adjustment mechanism 3. The feature is that a clamping mechanism 4 is provided on one side of the vertical adjustment mechanism 3, and an angle adjustment mechanism 6 is provided between the vertical adjustment mechanism 3 and the clamping mechanism 4 to realize the adjustment of the clamping mechanism 4 in space. The clamping mechanism 4 includes a drive mechanism and two clamping arms 46 that can move relative to each other. The end of the clamping arm 46 is provided with a replaceable clamping head 47 for clamping the part to be repaired. A quick-change mechanism 5 is provided at the connection between the clamping arm 46 and the clamping head 47.

[0021] In this embodiment, the appropriate clamping head 47 is first selected based on the shape and size of the part to be repaired and installed onto the clamping arm 46. This facilitates quick and easy replacement of the clamping head 47, improving its versatility and flexibility, and enabling it to adapt to workpieces of different shapes and sizes. The angle adjustment mechanism 6 allows for easy adjustment of the clamping mechanism 4's angle in space, enabling real-time adjustment and allowing the clamping head 47 to adapt to more types of workpieces. This reduces the need for specialized fixtures, lowers operating costs, and ensures the repair area remains in contact with the laser. The laser beam maintains optimal alignment, optimizing the repair path and alignment accuracy. During repair, the part to be repaired is placed between two clamping heads 47. By starting the drive motor 43, the drive motor 43 drives the forward and reverse threaded rods 44 to rotate, thereby causing the two clamping heads 47 to move relative to each other towards the center to clamp the part. This facilitates clamping of parts of different sizes and specifications, making it highly adaptable. Through the cooperation of the horizontal adjustment mechanism 2, the vertical adjustment mechanism 3, and the angle adjustment mechanism 6, the position and angle of the clamping heads 47 can be flexibly adjusted to ensure precise alignment between the area to be repaired and the laser beam, improving the efficiency and quality of part repair.

[0022] Furthermore, the horizontal adjustment mechanism 2 includes a horizontal guide rail 21 fixedly installed on one side of the top of the base 1 and a horizontal electric slider 22 slidably connected to the horizontal guide rail 21. The vertical adjustment mechanism 3 includes a vertical guide rail 31 fixedly connected to the top of the horizontal electric slider 22 and a vertical electric slider 32 slidably connected to the vertical adjustment mechanism 3. By setting the horizontal adjustment mechanism 2 and the vertical adjustment mechanism 3, the clamping mechanism 4 can be moved up, down, left, and right, so that the repair area of ​​the repaired workpiece can be quickly moved and aligned with the laser beam.

[0023] Furthermore, the angle adjustment mechanism 6 is a spherical hinge structure, including a ball socket 62 and a ball head 61 fixedly connected to one side of the vertical electric slider 32. In use, the angle adjustment mechanism 6 facilitates flexible adjustment of the angle of the clamping mechanism 4, enabling the clamping head 47 to adapt to more types of workpieces, reducing the need for special fixtures and lowering usage costs.

[0024] Furthermore, the drive mechanism includes a fixed plate 41 fixedly connected to one end of the ball head 61. A moving groove 42 is provided on the side of the fixed plate 41 away from the ball head 61. A drive motor 43 is fixedly installed on one side of the fixed plate 41. A forward and reverse threaded rod 44 is fixedly connected to the output end of the drive motor 43. Moving blocks 45 are symmetrically threaded at both ends of the forward and reverse threaded rod 44 located in the moving groove 42. One side of the moving block 45 is fixed to one side of the clamping arm 46. When in use, the drive motor 43 is started, and the drive motor 43 drives the forward and reverse threaded rod 44 to rotate, thereby driving the two clamping heads 47 to move towards the middle to clamp the parts. This is convenient for clamping parts of different sizes and specifications, and has strong applicability.

[0025] Furthermore, the quick-change mechanism 5 includes an insert block 51 fixedly connected to one side of the clamping head 47. The top of the insert block 51 has a locking hole 52. One side of the clamping arm 46 has a slot 53 adapted to the insert block 51. A mounting cylinder 54 is fixedly connected to the top of the clamping arm 46. A pull rod 55 is inserted into the top of the mounting cylinder 54. A sliding block 57 is fixedly connected to one end of the pull rod 55 inside the mounting cylinder 54. A return spring 56 is sleeved on the end of the pull rod 55 near the sliding block 57. A locking rod 58 is fixedly connected to the bottom of the sliding block 57. The locking rod 58 passes through the clamping arm 46 and extends into the slot 53 until it is inserted into the locking hole 52. The insert block 51 and the locking rod 58... The outer ends of the rod 58 are all rounded. The locking rod 58 is compatible with the locking hole 52. When in use, simply align the insert block 51 with the slot 53 and insert it. During the insertion process, the return spring 56 first compresses and then returns to its original position, so that the locking rod 58 is locked in the locking hole 52, thus completing the installation and fixing of the clamping head 47. Conversely, simply pull the pull rod 55 upward to move the locking rod 58 upward and disengage it from the locking hole 52, thus disassembling the clamping head 47. The operation is convenient and allows for quick replacement of the clamping head 47. It is easy to use and improves the versatility and flexibility of the clamping head 47, enabling it to adapt to workpieces of different shapes and sizes.

[0026] The working principle of this utility model is as follows: When in use, firstly, according to the shape and size of the part to be repaired, select a suitable clamping head 47 and install it on the clamping arm 46. During installation, simply align the insert block 51 with the slot 53 and insert it. During the insertion process, the return spring 56 performs a compression and then reset action, thereby causing the clamping rod 58 to engage in the clamping hole 52, thus completing the installation and fixing of the clamping head 47. Conversely, simply pull the pull rod 55 upward to move the clamping rod 58 upward and disengage it from the clamping hole 52, thus disassembling the clamping head 47. The operation is convenient and facilitates the quick replacement of the clamping head 47. It is easy to use and improves the versatility and flexibility of the clamping head 47, enabling it to adapt to workpieces of different shapes and sizes. Through the set angle adjustment mechanism 6, it is easy to realize the adjustment of the clamping mechanism 4 in space. The angle of the clamping mechanism 4 can be adjusted in real time, allowing the clamping head 47 to adapt to more types of workpieces, reducing the need for special fixtures, reducing the cost of use, and ensuring that the repair area always maintains the best alignment with the laser beam, thus optimizing the repair path and alignment accuracy.

[0027] During repair, the part to be repaired is placed between two clamping heads 47. By starting the drive motor 43, the drive motor 43 drives the forward and reverse threaded rods 44 to rotate, thereby causing the two clamping heads 47 to move towards the center to clamp the part. This makes it easy to clamp parts of different sizes and specifications, and it has strong applicability. Through the cooperation of the horizontal adjustment mechanism 2, the vertical adjustment mechanism 3 and the angle adjustment mechanism 6, the position and angle of the clamping heads 47 can be flexibly adjusted so that the area to be repaired is precisely aligned with the laser beam, which improves the efficiency and quality of part repair.

[0028] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
