Description

Technical Field

[0001] This utility model relates to the field of cladding repair technology, specifically a portable laser cladding repair device. Background Technology

[0002] Laser cladding, also known as laser bonding or laser coating, is a novel surface modification technology. It involves adding a cladding material to the surface of a substrate and then using a high-energy-density laser beam to fuse the material with a thin layer on the substrate surface, forming a metallurgically bonded cladding layer. This significantly improves the wear resistance, corrosion resistance, heat resistance, oxidation resistance, and electrical properties of the substrate material.

[0003] Extensive research revealed that Chinese Utility Model Patent Publication No. CN211367724U discloses a movable laser cladding repair device. This device addresses the shortcomings of existing laser cladding repair devices, such as limited mobility, inability to adjust the laser irradiation position, and difficulty in adapting to different parts, leading to inaccurate repairs. The device includes a substrate with a groove on its upper surface, a sliding rod at the bottom of a support column, and a movable rod at the top of the support column via a bearing. The movable rod has multiple slots and an adjustment slot.

[0004] While the above-mentioned solution has many advantages, it also has the following disadvantages: The device ensures that it moves along the groove by setting an annular groove and a sliding rod that can slide within the groove cavity. However, since the surface of the sliding rod is in direct contact with the inner wall of the groove, and the sliding rod is affected by the gravity and center of gravity shift of the cladding head and support column, it can only be moved by manually pushing the sliding rod or support column, which increases the difficulty of moving it and thus reduces the ease of movement of the laser cladding repair device.

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.

[0024] Example: Figure 1 - Figure 5 As shown, this utility model provides a technical solution for a mobile laser cladding repair device, including a device body 1 and a cladding head 2. The upper part of the device body 1 is provided with an installation groove 3. A worm wheel 4 and a worm 5 are rotatably connected to each other on the inner wall of the installation groove 3. A turntable 6 is fixedly connected to the upper part of the worm wheel 4. A support component 7 for supporting the cladding head 2 is provided on the upper part of the turntable 6. A servo motor 8 is installed on the device body 1. The output shaft of the servo motor 8 is fixedly connected to the end of the worm 5. The worm wheel 4 is rotatably connected to the inner wall of the installation groove 3 through a bearing. The servo motor 8 is electrically connected to a power supply. The cladding head 2 is located directly above the turntable 6.

[0025] The servo motor 8 drives the worm gear 5 to rotate, which in turn drives the worm wheel 4 to rotate. The worm wheel 4 rotates on the inner wall of the mounting groove 3 using bearings. At the same time, the worm wheel 4 drives the turntable 6 to rotate, which in turn drives the cladding head 2 and the support assembly 7 to rotate around the axis of the turntable 6.

[0026] like Figure 1 and Figure 5 As shown, the support assembly 7 includes a support rod 701, a first groove is provided at the top of the support rod 701, a threaded rod 703 is slidably disposed in the cavity of the first groove, a horizontal plate 704 is fixedly connected to the top of the threaded rod 703, and a threaded ring 702 is threadedly sleeved on the outer side of the threaded rod 703. The threaded ring 702 is rotatably connected to the top of the support rod 701. The cladding head 2 is installed at the bottom of the horizontal plate 704. The threaded rod 703 and the horizontal plate 704 are arranged perpendicular to each other, and a support diagonal rod is fixedly connected between the horizontal plate 704 and the threaded rod 703.

[0027] By rotating the threaded ring 702, the threaded ring 702 uses the threaded rod 703 to drive the horizontal plate 704 and the cladding head 2 to rise and fall, thereby facilitating the adjustment of the height of the cladding head 2.

[0028] like Figure 1 and Figure 5 As shown, a second groove is provided at the top of the support rod 701, and a stabilizing rod 14 is slidably arranged in the second groove. The top of the stabilizing rod 14 is fixedly connected to the bottom of the horizontal plate 704. The stabilizing rod 14 and the threaded rod 703 are arranged parallel to each other.

[0029] The stabilizer bar 14 is used to stabilize the threaded rod 703 and the cross plate 704, so that the threaded rod 703 cannot rotate in the first slide groove cavity, but can only slide up and down.

[0030] like Figure 1 and Figure 5 As shown, a bevel ring 16 is fixedly sleeved on the outer side of the threaded ring 702. A bevel gear 15 is meshed with one side of the bevel ring 16. One side of the bevel gear 15 is rotatably connected to the surface wall of the support rod 701, and a rocker plate 17 is fixedly connected to the other side of the bevel gear 15. The bevel gear 15 and the bevel ring 16 are arranged perpendicular to each other.

[0031] By rotating the rocker 17, the rocker 17 drives the bevel gear 15 to rotate the bevel ring 16, and the bevel ring 16 drives the threaded ring 702 to rotate.

[0032] The upper part of the bevel ring 16 has a fixing opening, and the bevel ring 16 is fixedly sleeved on the outside of the threaded ring 702 through the fixing opening.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, a convex rod 9 is fixedly connected to the upper part of the turntable 6, and a mounting plate 10 is fixedly connected to the bottom of the support rod 701. A convex groove 11 adapted to the convex rod 9 is opened at the bottom of the mounting plate 10. The vertical section of the convex rod 9 is a convex-shaped structure, and the vertical section of the convex groove 11 is a convex-shaped cavity.

[0034] A support ramp is fixedly connected between the mounting plate 10 and the support rod 701. An arc-shaped triangular ramp is fixedly connected to both sides of the support rod 701 adjacent to the support ramp. The bottom of the triangular ramp contacts the upper part of the turntable 6. The support ramp and the triangular ramp can improve the stability of the support rod 701.

[0035] like Figure 1 and Figure 2 As shown, a limit rod 12 is connected to the threaded hole on the upper part of the mounting plate 10. A slot 13 is provided on the upper part of the convex rod 9 at the corresponding position relative to the threaded hole. The bottom end of the limit rod 12 is inserted into the cavity of the slot 13.

[0036] The support assembly 7 can be quickly disassembled and assembled by inserting the convex rod 9 into the cavity of the convex groove 11 on the mounting plate 10. After assembling the mounting plate 10 on the convex rod 9, the limiting rod 12 on the mounting plate 10 is rotated so that the bottom end of the limiting rod 12 extends out of the threaded hole cavity and is inserted into the cavity of the slot 13, thereby completing the mutual assembly and fixation of the convex rod 9 and the mounting plate 10.

[0037] like Figure 3 and Figure 4As shown, a vertical rod 18 is fixedly connected to the inner wall of the mounting groove 3, and a platform plate 19 is fixedly connected to the top of the vertical rod 18. A through vertical groove is opened on the upper part of the worm gear 4, and the worm gear 4 is rotated and sleeved on the outside of the vertical rod 18 through the vertical groove. A through opening is opened on the upper part of the turntable 6, and the turntable 6 is rotated and sleeved on the outside of the vertical rod 18 through the opening.

[0038] Platform plate 19 is designed to ensure that the rotating support assembly 7 does not rotate along with it.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
