Description

Technical Field

[0001] The utility model relates to the technical field of core wire processing, in particular to a core wire welding concentric tooling. Background Art

[0002] With the rapid development of modern medical technology, vascular interventional surgery has become an important means for treating various cardiovascular diseases. In vascular interventional surgery, the welding quality of the core wire and the metal tube directly affects the performance of the surgical instrument and the treatment effect of the patient.

[0003] Traditional welding methods often rely on manual adjustment of the position of the core wire to ensure precise concentric welding with the metal tube. Since manual operation usually requires repeated trial and error and delicate fine-tuning, this process is not only time-consuming but also inefficient. Moreover, when high-precision three-dimensional spatial positioning is required, it is usually difficult to achieve precise fine-tuning of the alignment by manual adjustment. This inaccurate alignment not only makes the welding surface prone to unevenness but also directly affects the overall quality of the welding.

[0004] Therefore, a core wire welding concentric tooling is needed to solve the above problems. Summary of the Utility Model

One side of the X-axis slider away from the X-axis platform is connected to the lifting assembly, and the moving direction of the Y-axis slider is perpendicular to the moving direction of the X-axis slider; the servo motors control the rotation of the Y-axis lead screw and the X-axis lead screw, so as to quickly drive the Y-axis slider and the X-axis slider to move, and thus realize the quick adjustment of the moving seat.

[0011] Preferably, for precise height control, the lifting assembly includes a second servo cylinder with two ends respectively fixedly connected to the side of the X-axis slider away from the X-axis platform and the bottom of the moving seat, and telescopic rods arranged on both sides of the second servo cylinder with two ends respectively fixedly connected to the X-axis slider and the moving seat; the second servo cylinder serves as a driving source, and can precisely control the telescopic movement of its movable end to achieve precise adjustment of the height of the moving seat, without manual adjustment, ensuring the accuracy of welding.

[0012] Preferably, for stable clamping of the core wire, the clamping assembly includes mounting brackets symmetrically and slidably arranged in the receiving groove, rubber rollers rotatably connected to the side of the two mounting brackets close to each other and in contact with the core wire, a first servo cylinder fixedly arranged on the side of the two mounting brackets away from each other and fixedly connected to the moving seat, and guide rods arranged on both sides of the first servo cylinder and fixedly connected to the mounting brackets, and the guide rods are slidably connected to the moving seat; by driving the rubber rollers to contact the core wire by the first servo cylinder, a good clamping force can be provided, and the rubber material of the rubber rollers also avoids damage to the core wire caused by direct rigid contact. Moreover, the design of this clamping assembly can also be adjusted and adapted according to core wires of different diameters or shapes, with strong adaptability.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] The present invention provides a concentric tooling for core wire welding, as Figures 1-4 shown. The concentric tooling for core wire welding includes a base 1, an XY-axis adjustment assembly 2 provided on the base 1, a moving seat 3 provided above the XY-axis adjustment assembly 2 on the base 1, an accommodating groove 31 opened on the moving seat 3 for placing the core wire, a fixed seat 4 fixedly provided on one side of the base 1 corresponding to the moving seat 3 for placing the metal tube, and a lifting assembly 5 provided on the XY-axis adjustment assembly 2 for adjusting the height of the moving seat 3; a clamping assembly 32 for fixing the core wire is provided in the accommodating groove 31.

[0031] During use, first place the metal pipe to be welded on the fixed seat 4 and ensure that the metal pipe is stable and in the correct position. Then, place the core wire in the receiving groove 31 of the moving seat 3 and adjust the clamping assembly 32 to fix the core wire in the receiving groove 31. Next, start the lifting assembly 5 to adjust the height of the moving seat 3 and the core wire in the receiving groove 31 to ensure that the height at the welding point of the core wire and the metal pipe is the same. Then, start the XY-axis adjustment assembly 2 to adjust the moving seat 3 and the core wire in the receiving groove 31 in the horizontal direction to ensure that the core wire is aligned with the axis of the metal pipe to achieve the effect of concentric welding. After the adjustment is completed, use a welding device to weld the core wire and the metal pipe. During the welding process, the XY-axis adjustment assembly 2 and the lifting assembly 5 can be finely adjusted to ensure the accuracy of the welding position.

[0032] Specifically, the clamping assembly 32 includes mounting brackets 321 symmetrically and slidably arranged in the receiving groove 31, rubber rollers 322 rotatably connected to the adjacent sides of the two mounting brackets 321 and in contact with the core wire, first servo electric cylinders 323 fixedly arranged on the opposite sides of the two mounting brackets 321 and fixedly connected to the moving seat 3, and guide rods 324 arranged on both sides of the first servo electric cylinders 323 and fixedly connected to the mounting brackets 321. The guide rods 324 are slidably connected to the moving seat 3;

[0033] After placing core wires of different sizes or shapes to be welded in the receiving groove 31, first ensure that the position of the core wire is roughly aligned with the rubber rollers 322 of the clamping assembly 32. Then, start the corresponding first servo electric cylinder 323 to move the two mounting brackets 321 closer or farther away. As the two mounting brackets 321 move closer or farther away, the rubber rollers 322 connected to the two mounting brackets 321 can move closer to both sides of the placed core wire and contact it. When the rubber rollers 322 on the two mounting brackets 321 are in full contact with the core wire, as the first servo electric cylinder 323 continues to drive, the rubber rollers 322 on the two mounting brackets 321 can tightly clamp the core wires of different sizes or shapes placed in the receiving groove 31. Due to the rubber material of the rubber rollers 322, the contact wear between the core wire and the rubber rollers 322 can be avoided. After the welding is completed, the corresponding first servo electric cylinder 323 can be started to drive the rubber rollers 322 on the two mounting brackets 321 away from both sides of the core wire.

[0034] Among them, in order to prevent the guide rod 324 from detaching from the moving seat 3, a stop block 325 is fixedly installed at the end of the guide rod 324 close to the moving seat 3; the design of the stop block 325 can prevent the guide rod 324 from sliding excessively or accidentally detaching from the moving seat 3 during the movement, thereby enhancing the stability of the clamping assembly 32.

[0035] Further, the fixed seat 4 includes brackets 41 symmetrically and fixedly installed on one side of the base 1 corresponding to the moving seat 3, a first arc-shaped clamping plate 42 and a second arc-shaped clamping plate 43 symmetrically arranged on the two brackets 41, an adjusting screw rod 44 rotatably connected to one side of the first arc-shaped clamping plate 42 and screwed to the corresponding side of the second arc-shaped clamping plate 43, and a support rod fixedly connected to the other side of the first arc-shaped clamping plate 42 and passing through the corresponding side of the second arc-shaped clamping plate 43. One side of the first arc-shaped clamping plate 42 away from the second arc-shaped clamping plate 43 is fixedly connected to the tops of the two brackets 41, and the second arc-shaped clamping plate 43 is slidably connected to the support rod;

[0036] First, according to the size of the metal pipe, rotate the two adjusting screw rods 44. Since the adjusting screw rods 44 are rotatably connected to the first arc-shaped clamping plate 42 and screwed to the second arc-shaped clamping plate 43, and the other side of the first arc-shaped clamping plate 42 is slidably connected to the support rod, rotating the adjusting screw rods 44 will cause the second arc-shaped clamping plate 43 to approach or move away from the first arc-shaped clamping plate 42. Thus, the position of the second arc-shaped clamping plate 43 can be adjusted according to the size and clamping requirements of the metal pipe until the metal pipe is stably and evenly clamped between the first arc-shaped clamping plate 42 and the second arc-shaped clamping plate 43. After the metal pipe is stably clamped, the subsequent steps of welding can be continued. After welding is completed, if it is necessary to replace or remove the metal pipe, only need to rotate the adjusting screw rods 44 in the reverse direction to make the second arc-shaped clamping plate 43 move away from the first arc-shaped clamping plate 42, and then remove the metal pipe.

[0037] Furthermore, the lifting assembly 5 includes a second servo cylinder 51 with two ends respectively fixedly connected to the side of the X-axis slider 26 away from the X-axis platform 24 and the bottom of the moving seat 3, and telescopic rods 52 arranged on both sides of the second servo cylinder 51 and with two ends respectively fixedly connected to the X-axis slider 26 and the moving seat 3;

[0038] After using the clamping assembly 32 to fix the core wire to be welded in the receiving groove 31, the second servo cylinder 51 can be started to push the moving seat 3 to lift. Since the moving seat 3 is connected with the telescopic rods 52, under the telescopic guiding action of the telescopic rods 52, the moving seat 3 can stably drive the core wire clamped in the receiving groove 31 to lift, so that the height difference between the core wire in the receiving groove 31 and the metal pipe can be accurately adjusted.

[0039] Further, the XY-axis adjustment assembly 2 includes a Y-axis platform 21 fixedly installed on the base 1, a Y-axis lead screw 22 rotatably connected to the side of the Y-axis platform 21 away from the base 1, a Y-axis slider 23 slidably connected to the Y-axis platform 21 and threadedly engaged with the Y-axis lead screw 22, an X-axis platform 24 fixedly connected to the side of the Y-axis slider 23 away from the Y-axis platform 21, an X-axis lead screw 25 rotatably connected to the side of the X-axis platform 24 away from the Y-axis slider 23, an X-axis slider 26 slidably connected to the X-axis platform 24 and threadedly engaged with the X-axis lead screw 25, and servo motors 27 respectively fixedly installed on the Y-axis platform 21 and the X-axis platform 24 for driving the Y-axis lead screw 22 and the X-axis lead screw 25 to rotate. The side of the X-axis slider 26 away from the X-axis platform 24 is connected to the lifting assembly 5, and the moving direction of the Y-axis slider 23 is perpendicular to the moving direction of the X-axis slider 26;

[0040] After adjusting the height of the core wire, the servo motor 27 connected to the Y-axis lead screw 22 can be started. Since the Y-axis lead screw 22 is threadedly engaged with the Y-axis slider 23 sliding on the Y-axis platform 21, and the Y-axis slider 23 is fixedly connected to the X-axis platform 24, when the corresponding servo motor 27 is started to drive the Y-axis lead screw 22 to rotate, the Y-axis slider 23 can move in a direction perpendicular to the moving direction of the X-axis slider 26, so as to realize the position adjustment of the core wire in the horizontal direction of the Y-axis. When the position adjustment of the Y-axis is in place, then start the servo motor 27 connected to the X-axis lead screw 25. Since the X-axis lead screw 25 is threadedly engaged with the X-axis slider 26 sliding on the X-axis platform 24, and the X-axis slider 26 is connected to the moving seat 3 through the lifting assembly 5, when the corresponding servo motor 27 drives the X-axis lead screw 25 to rotate, the X-axis slider 26 can drive the moving seat 3 to move in the X-axis direction, and then the position adjustment of the core wire in the horizontal direction of the X-axis can be realized.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
