Description

Technical Field

[0001] This utility model relates to the field of alloy processing technology, specifically to a welding device for nickel-titanium alloy materials. Background Technology

[0002] Nickel-titanium alloy is a metallic material with shape memory effect and superelasticity. It is composed of nickel and titanium in a near-equal atomic ratio. When processing nickel-titanium alloy materials, resistance spot welding machines are usually used to weld them. Existing resistance welding machines are widely used because of their low cost, small heat-affected zone, and ease of operation.

[0003] Existing resistance spot welding machines require operators to manually set parameters such as current, voltage, and energizing time before welding. Therefore, when welding small, high-precision parts, problems such as burn-through, incomplete welds, and weld point misalignment are prone to occur. Furthermore, for ease of handling, space is usually reserved on both sides of the material to be welded, which can easily lead to misalignment of the welding position if the positioning is inaccurate. To address these issues, we propose a welding device for nickel-titanium alloy materials. Utility Model Content

[0004] The purpose of this invention is to provide a welding device for nickel-titanium alloy materials to solve the problem of inaccurate positioning caused by the existence of reserved space in the background art.

[0014] 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.

[0015] Please see Figures 1-2 This utility model provides a technical solution: a nickel-titanium alloy welding device, including a support frame 1 and a welding head 5. A support base 2 is fixedly connected to the bottom of the support frame 1. A bearing mechanism 3 for bearing the material to be welded is provided on the top of the support base 2. A moving mechanism 4 for driving the welding head 5 to move and weld is provided on the support frame 1. Two sets of laser detectors 9 for identifying the position of the material to be welded are provided on the moving mechanism 4. Two sets of ultrasonic detectors 10 for identifying the position of the material to be welded are fixedly connected to one end of the support frame 1 through a fixing frame 6. Two sets of pressing and positioning mechanisms 7 for adjusting the position of the material to be welded inside the bearing mechanism 3 are provided on the support frame 1. A driving mechanism 8 for moving the pressing and positioning mechanisms 7 up and down to press and clamp is provided on the support frame 1.

[0016] The supporting mechanism 3 can support the material to be welded. The laser detector 9 and ultrasonic detector 10 can monitor the position of the material in real time to prevent misalignment. The pressing and positioning mechanism 7 and the driving mechanism 8 work together to adjust the position of the material in the supporting mechanism 3 and press it into position. This can prevent the material from shifting during the welding process and ensure that the material is welded accurately. Then, the moving mechanism 4 can drive the welding head 5 to move along three axes to perform welding on the material.

[0017] Please see Figures 1-4The moving mechanism 4 includes a first screw slide 11, a connecting frame 12, a second screw slide 13, a first connecting plate 14, and a third screw slide 15. The first screw slide 11 is fixedly installed on both sides of the support frame 1. The connecting frame 12 is fixedly connected to the moving end of the first screw slide 11. The second screw slide 13 is fixedly connected to one side of the connecting frame 12. The first connecting plate 14 is fixedly connected to the moving end of the second screw slide 13. The third screw slide 15 is fixedly connected to the first connecting plate 14. The welding head 5 is fixedly installed on the moving end of the third screw slide 15 through a fixed seat 16. The first fixed plate 17 is fixedly connected to the bottom of the fixed seat 16.

[0018] Among them, the first screw slide 11, the second screw slide 13 and the third screw slide 15 correspond to the X, Y and Z axis movements respectively, which can synchronously drive the fixed seat 16 and the welding head 5 to achieve three-dimensional spatial movement, thereby realizing all-round welding of the material in the bearing mechanism 3.

[0019] Please see Figures 1-2 The bearing mechanism 3 includes a bearing seat 18, a second connecting plate 19, and a positioning mold 20. The bearing seat 18 is fixedly installed on the support frame 1. The top of the bearing seat 18 is fixedly connected to the positioning mold 20, which is used to support the material to be welded, through the second connecting plate 19. The positioning mold 20 is used to support the material to be welded. Arc-shaped pick-up grooves are opened on both sides of the inner wall of the positioning mold 20.

[0020] The material to be welded can be placed in the positioning mold 20, and the arc-shaped picking groove on the positioning mold can facilitate the picking and placing of the material.

[0021] Please see Figures 1-4 The clamping and positioning mechanism 7 includes a movable seat 21, a double-axis screw 22, a drive motor 23, a threaded sleeve 24, and a clamping seat 28. The double-axis screw 22 is rotatably connected inside the movable seat 21. The drive motor 23 is fixedly connected to one end of the movable seat 21. The output end of the drive motor 23 is fixedly connected to the double-axis screw 22. The threaded sleeve 24 is threadedly connected to the outside of the double-axis screw 22. A movable plate 25 is fixedly connected to the top of the threaded sleeve 24. A slide rail 26 is fixedly connected to one side of the movable plate 25. An "L"-shaped clamping seat 28 is slidably connected to the slide rail 26 via a slider 27.

[0022] After the material is placed, the drive motor 23 drives the dual-shaft screw 22 to rotate, which in turn drives the two sets of threaded sleeves 24 that are threaded to the dual-shaft screw 22 to move synchronously relative to each other. Then, the moving plate 25 and the clamping seat 28 are pushed closer to each other, and the clamping seat 28 is used to correct and position the material.

[0023] Please see Figures 1-4The drive mechanism 8 includes a guide groove 29, a second fixing plate 30, and a drive rod 31. The clamping seat 28 has a guide groove 29 that is inclined through it. The top of the support frame 1 and both sides of the movable seat 21 are fixedly connected to the second fixing plate 30. The two sets of second fixing plates 30 are fixedly connected to the drive rod 31 that is inserted into the guide groove 29.

[0024] When the clamping seat 28 moves, the fixed drive rod 31 is inserted into the guide groove 29. Since the guide groove 29 is inclined, the two work together to guide the clamping seat 28, so that it moves downward along the slide rail 26 via the slider 27. After the material position is adjusted, the material is clamped and positioned.

[0025] In use, firstly, the supporting mechanism 3 supports the material to be welded. Then, the laser detector 9 and ultrasonic detector 10 monitor the material's position in real time to prevent misalignment. Next, the clamping and positioning mechanism 7 and the driving mechanism 8 work together to adjust the position of the material within the supporting mechanism 3 and clamp it in place, preventing material displacement during welding and ensuring precise welding. Then, the moving mechanism 4 drives the welding head 5 to move along three axes for welding. The first screw slide 11, the second screw slide 13, and the third screw slide 15 correspond to the X, Y, and Z axes respectively, synchronously driving the fixed base 16 and the welding head 5 to move in three-dimensional space, thereby ensuring the support... The material inside the carrier 3 is welded from all directions. The material to be welded can be placed into the positioning mold 20. The arc-shaped picking groove on the positioning mold facilitates the picking and placing of the material. After the material is placed, the drive motor 23 drives the double-shaft screw 22 to rotate, which in turn drives the two sets of threaded sleeves 24 that are threaded to the double-shaft screw 22 to move synchronously relative to each other. Then, the moving plate 25 and the pressing seat 28 are pushed closer to each other. The pressing seat 28 is used to correct and position the material. When the pressing seat 28 moves, the fixed drive rod 31 is inserted into the guide groove 29. Since the guide groove 29 is inclined, the two work together to guide the pressing seat 28, so that it moves downward along the slide rail 26 through the slider 27. After the material position is adjusted, the material is pressed and positioned.
