Description

Technical Field

[0001] This utility model relates to the field of laser cladding technology, and in particular to a liftable welding support for laser cladding. Background Technology

[0002] Laser cladding, also known as laser welding 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, thus forming a metallurgically bonded cladding layer.

[0003] Under current technological conditions, the workpiece support design used on laser cladding platforms is fixed. This limitation is that when dealing with small workpieces, the clamps, constrained by their physical dimensions, cannot guarantee stable clamping even at their smallest clamping position, or may even be unable to clamp at all. This leads to easy displacement of the workpiece during the laser cladding process. Furthermore, the range of motion of the laser cladding torch is limited, preventing it from reaching preset long-distance positions. Consequently, some workpieces are excluded from the laser cladding process because they exceed the torch's effective working radius.

[0004] To address this issue, we propose a height-adjustable weldment support for laser cladding, which solves the problems in existing technologies where the clamping and positioning of small weldments is unstable and the height is insufficient to allow them to enter the effective working range of the laser cladding gun.

[0042] like Figure 1-9 As shown, this utility model provides a liftable welding support for laser cladding, including: a positioning component 1, a lifting component 2, and a mounting component 3.

[0043] Positioning component 1 is located at the top of lifting component 2 and is used to clamp and position small-sized weldments. Lifting component 2 is an adjustable lifting structure used to control the lifting and lowering of positioning component 1. Mounting component 3 is located at the bottom of lifting component 2. Mounting component 3 is placed in the fixture of the external worktable and clamped and fixed, so that the weldment support is connected to the laser cladding worktable as one unit. When the weldment is small, mounting component 3 is placed in the fixture of the external worktable and clamped and fixed by the fixture of the laser cladding worktable. Then, the small-sized weldment is placed in positioning component 1, which clamps and fixes the weldment. Then, lifting component 2 is used to control positioning component 1 to rise, moving the weldment into the working range of the laser cladding gun head, completing the laser cladding operation.

[0044] In one embodiment, please refer to Figure 1-4The positioning component 1 includes a housing 10, with a positioning groove 100 in the middle of the housing 10, which can be used to place small welding parts. Two sliders 11 are respectively provided at both ends of the housing 10, each slider 11 can slide along the inner wall of the positioning groove 100. A bidirectional screw 12 is also provided on the inner side of both ends of the positioning groove 100, passing through the two sliders 11 and threadedly connected to them. The two sliders 11 on the same side are symmetrically distributed at both ends of the bidirectional screw 12. Two clamping plates 13 are also provided inside the positioning groove 100. A double-layer push rod 14 is connected between each clamping plate 13 and the two sliders 11 on the same side. A rotating shaft is connected to both ends of the double-layer push rod 14, and the double-layer push rod 14 is rotatably connected to the clamping plate 13 and the slider 11 respectively through the rotating shaft. The front end of the housing 10 is equipped with a drive unit 15, which drives two bidirectional screws 12 to rotate synchronously. Both ends of the bidirectional screws 12 pass through the inner sidewalls of the positioning groove 100 and are rotatably connected to the sidewalls of the positioning groove 100. In use, after placing the small weldment into the positioning groove 100, the drive unit 15 is activated. The drive unit 15 controls the rotation of the two bidirectional screws 12, and each bidirectional screw 12 controls two sliders 11 on the same side to move towards each other. The sliders 11, through the double-layer push rod 14, push the clamping plates 13 closer together, clamping and fixing the small weldment in the center of the positioning groove 100. This device can achieve clamping and positioning of small weldments, avoiding unstable clamping or inability to clamp due to the small size of the weldment.

[0045] In one embodiment, please refer to Figure 4 The drive unit 15 includes a motor 150 and two sets of pulleys 151. The output shaft of the motor 150 passes through and fixes the center of one end hub of each set of pulleys 151. A bidirectional screw 12 is connected to the other end hub of each set of pulleys 151. The motor 150 can drive the two sets of pulleys 151 to rotate, so that each set of pulleys 151 drives a bidirectional screw 12 to rotate.

[0046] In one embodiment, please refer to Figure 4-5 The clamping plate 13 includes a mounting base 130 connected to a double-layer push rod 14 on one side, and a pressing plate 131 on the other side of the mounting base 130. The upper end of the mounting base 130 has slots 132 on both sides, and the pressing plate 131 has two T-shaped locking blocks 133 at one end near the mounting base 130. In use, the T-shaped locking blocks 133 can be inserted into the slots 132 to connect the pressing plate 131 to the mounting base 130. To remove, the pressing plate 131 can be removed by simply pulling out the T-shaped locking blocks 133. It should be noted that since the shape and size of small weldments are not fixed, the pressing plate 131 used to clamp the weldments also needs to be available in various models. The above-described disassembly and assembly method allows for quick replacement of the pressing plate 131.

[0047] In one embodiment, please refer to Figure 1-3A top rod 16 is elastically connected to the bottom center of the box body 10. The top rod 16 passes through the middle of the box body 10, and a top cover 17 and a button 18 are respectively connected to the two ends of the top rod 16. The top cover 17 is located inside the box body 10, and the upper surface of the top cover 17 is lower than the height of the inner bottom wall of the box body 10. After the weldment is laser cladding completed, the button 18 is pushed upward from the bottom of the box body 10. The button 18 pushes the top cover 17 upward through the top rod 16, thereby pushing and lifting the weldment, so that the weldment exceeds the positioning groove 100. After the operator removes the weldment, the button 18 is released, and it automatically resets under the elastic action.

[0048] In one embodiment, please refer to Figure 1 and Figure 6 Push plates 19 are elastically connected to the inner walls of both the front and rear ends of the positioning groove 100. Telescopic rods are also connected between the push plates 19 and the side walls of the positioning groove 100, allowing the push plates 19 to slide back and forth relative to the side walls of the positioning groove 100. Several ball bearings 190 are provided on the other side of the push plates 19. The line connecting the two push plates 19 and the line connecting the two clamping plates 13 forms a cross shape. Under the action of elasticity, the push plates 19 can push the weldment to the center of the positioning groove 100 in the front-back direction. The clamping plates 13 then hold the weldment and push it to the center of the positioning groove 100. The ball bearings 190 reduce the friction between the weldment and the push plates 19, allowing the weldment to move left and right with the clamping plates 13 while being held by the two push plates 19.

[0049] In one embodiment, please refer to Figure 7-8 The lifting component 2 includes a sleeve 20, with a slide rod 21 in the middle of the sleeve 20. The slide rod 21 passes through the sleeve 20 and is slidably connected to it. A rack 22 is connected to the front end of the slide rod 21. A gear 23 corresponding to the rack 22 is located at the top of the sleeve 20. A second motor 24 is located at the front end of the sleeve 20. The second motor 24 drives the gear 23 to rotate forward and backward. The second motor 24 and the drive gear 23 can be connected via a synchronous belt and pulley. In use, by starting the second motor 24, the second motor 24 drives the drive gear 23 to rotate, the drive gear 23 drives the rack 22 to rise and fall, and the rack 22 drives the slide rod 21 connected to the rear end to rise and fall. This device can control the raising and lowering of the positioning component 1, making it easier to push the small welding parts into the range of the laser cladding gun head, solving the problem that small welding parts cannot enter the range of motion of the gun head for laser cladding due to insufficient height.

[0050] In one embodiment, please refer to Figure 7-8 The top of the slide bar 21 has a Y-shaped structure. The upper end of the slide bar 21 is connected to the positioning component 1. More precisely, the upper end of the slide bar 21 is connected to the bottom of the box 10. The Y-shaped structure at the top of the slide bar 21 leaves space for the operation button 18.

[0051] In one embodiment, please refer to Figure 9 The mounting component 3 includes a square base 30. Arc-shaped pads 31 are provided on the four side edges of the square base 30. A π-shaped block 32 is provided on the side of the arc-shaped pad 31 close to the base 30. A groove 33 corresponding to each of the four arc-shaped pads 31 is provided at the lower end of the base 30. Slots 34 corresponding to the π-shaped blocks 32 are provided on the four side edges of the base 30, and the slots 34 are connected to the grooves 33. On the workbench for laser cladding, the common fixtures are divided into those for clamping cylindrical structures and square structures. The square base 30 corresponds to the square fixture. When the π-shaped block 32 is inserted into the corresponding groove 33, the arc-shaped pads 31 are placed on the four side edges of the square base 30 to form a cylindrical structure, corresponding to the fixture for clamping cylindrical workpieces, so that the mounting component 3 can be clamped by the fixture for clamping cylindrical or square workpieces.

[0052] In one embodiment, please refer to Figure 9 A notch is provided in the middle of the π-shaped block 32, and a finger can be inserted into the notch to pull the π-shaped block 32 to separate the arc-shaped pad 31 from the groove 33.
