Description

Technical Field

[0001] This invention belongs to the field of pipeline welding technology, and specifically relates to a welding device and equipment for flexible hose joints. Background Technology

[0002] In the manufacturing process of flexible hoses for nuclear power plants, the hoses need to be welded to fittings. Traditional welding methods often require the welding torch to move in a circular motion around the workpiece, or the hose to be manually rolled to achieve full welding. This can easily lead to misalignment or skew between the hoses, causing numerous welding problems. Operators need to adjust the relative positions of the hoses while flipping them to ensure weld quality. This method is not only complex and inefficient, but also prone to uneven weld quality. Summary of the Invention

[0003] The purpose of this invention is to provide a flexible hose joint welding device and equipment, which can reduce the difficulty of pipe welding and effectively improve welding efficiency and welding quality.

[0004] Technical solution to achieve the purpose of this invention:

[0005] A flexible hose joint welding device includes a base, grippers, and a drive assembly. The base supports and stabilizes the tooling, and grippers are rotatably connected to the base for holding workpieces. The drive assembly is provided on the base and controls the rotation of the grippers to drive the workpieces to rotate. The drive assembly includes a geared disc fixedly connected to the grippers, a motor fixedly connected to the base, and a drive gear fixedly connected to the output shaft of the motor. The drive gear meshes with the geared disc.

[0006] A rotating seat is rotatably connected to the base, a gripper is rotatably connected to the rotating seat, and a drive assembly is disposed on the rotating seat. A limiting assembly for restricting the rotation of the rotating seat is disposed on the base.

[0007] The limiting assembly includes a worm gear and a worm that mesh with each other. The rotating seat is rotatably connected to the base via a rotating shaft. The rotating seat and the rotating shaft are fixedly connected. The extension line of the rotating shaft passes through the rotating seat and rotates on the base. The worm gear is coaxially fixedly connected to the rotating shaft, and the worm is rotatably connected to the base.

[0008] The gripper is a three-jaw chuck, and the central axis of the three-jaw chuck is collinear with the rotation axis of the gripper on the rotating seat.

[0009] The gripper includes a connecting seat and a three-jaw chuck disposed on the connecting seat. The connecting seat is rotatably connected to a rotating seat. Several connecting rods are hinged to the three-jaw chuck. A slider is hinged to the end of the connecting rod away from the three-jaw chuck. The slider is slidably disposed on the connecting seat, and the sliding direction of the slider is parallel to the radial direction of the connecting seat. The connecting seat is provided with a control component for controlling the sliders to move closer to or further away from each other.

[0010] The control component includes a rotating disk rotatably connected to the connecting seat, a guide groove on the rotating disk, a support rod on the slider, and the support rod inserted into the guide groove. The rotation of the rotating disk can push the slider to slide radially along the connecting seat.

[0011] A driven bevel gear is coaxially arranged on the rotating disk, and a driving bevel gear is rotatably connected to the rotating disk. The driving bevel gear and the driven bevel gear mesh with each other.

[0012] The base is provided with a support frame, and the support frame is provided with rollers for supporting the workpiece.

[0013] The support frame includes a base plate fixedly connected to the base. A pair of support frames are hinged to the base plate. Each support frame has a support arm hinged to it. A movable seat is hinged to the end of each support arm away from the support frame. A double-ended stud is rotatably connected to the base plate. The double-ended stud passes through the two movable seats and is threadedly connected to the two movable seats. The threaded sections of the two movable seats corresponding to the double-ended studs have opposite directions of rotation. Rollers correspond one-to-one with the support frames. The rollers are rotatably connected to the corresponding support frames. The central axes of the two rollers intersect to form a limiting groove for supporting the workpiece.

[0014] A hose hinge welding device, the device comprising a means for clamping the pipe and the hinge and a welding torch mechanism, the means being a hose hinge welding device.

[0015] The beneficial technical effects of this invention are as follows:

[0016] 1. In the flexible hose joint welding device provided by the present invention, the base is used to support and stabilize the entire tooling, and a clamp is rotatably connected on it. The clamp is used to hold the workpiece to be welded. A driving component is provided on the base.

[0017] 2. In the flexible hose joint welding device provided by the present invention, the rotating disk rotates and guides the support rod through the guide groove, thereby driving each slider to move closer or further away from each other, so that the three-jaw chuck can move closer or further away from the connecting seat, thereby realizing the axial fine adjustment of the workpiece.

[0018] 3. The flexible hose joint welding device provided by the present invention rotates the double-ended stud, which drives the two moving seats to move closer or further apart. Through the linkage rotation of the connecting rod, the two rollers are driven to tilt towards or away from each other to adjust the size of the limiting groove, support workpieces of different diameters, reduce the workpieces from shifting or vibrating during rotation, and help improve the stability and accuracy of welding.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] like Figure 1-2 As shown, this embodiment provides a flexible hose joint welding device, including a base 1, a rotating seat 11 rotatably connected to the base 1, and a gripper 12 rotatably connected to the rotating seat 11. The gripper 12 is a three-jaw chuck for clamping workpieces, wherein the rotation axis of the rotating seat 11 is perpendicular to the rotation axis of the gripper 12 on the rotating seat 11. A limit component 2 is provided on the base 1 to limit the rotation of the rotating seat 11. A drive component 3 is provided on the rotating seat 11 to control the rotation of the gripper 12. The gripper 12 is used to clamp the pipe workpiece to be welded, and the drive component 3 achieves automatic rotation of the pipe workpiece by driving the gripper 12 to rotate.

[0030] The drive assembly 3 includes a geared disc 31 fixedly connected to the gripper 12. The central axis of the geared disc 31 is collinear with the rotation axis of the gripper 12 on the rotating seat 11. The rotating seat 11 is provided with a groove 32 for accommodating the geared disc 31. A motor 33 is fixedly connected to the rotating seat 11, and the motor 33 is located on the side of the rotating seat 11 away from the gripper 12. The output shaft of the motor 33 extends into the groove 32, and a drive gear 34 is fixedly connected to the output shaft of the motor 33. The drive gear 34 meshes with the geared disc 31. When the motor 33 is working, its output shaft drives the drive gear 34 to rotate, thereby driving the geared disc 31 and the gripper 12 to rotate synchronously, realizing the rotation of the pipe workpiece around its own axis.

[0031] The limiting assembly 2 includes a meshing worm gear 21 and a worm 22. Rotating seats 11 are fixedly connected to both sides by rotating shafts, with the axis of the shafts perpendicular to the rotation axis of the gripper 12 on the rotating seat 11. The rotating seat 11 is rotatably connected to the base 1 via the rotating shafts. The worm gear 21 is coaxially fixedly connected to one of the rotating shafts, and the worm 22 is rotatably connected to the base 1. It can be rotated manually or electrically, thereby driving the worm gear 21 to rotate and thus causing the rotating seat 11 to flip. By adjusting the position or angle of the worm 22, precise control of the rotation of the rotating seat 11 can be achieved, thereby adjusting the welding angle of the pipe workpiece.

[0032] The implementation principle of this invention is as follows: The base 1 is used to support and stabilize the entire fixture, and a clamping jaw 12 is rotatably connected to it. The clamping jaw 12 is used to clamp the workpiece to be welded. A driving component 3 is provided on the base 1. The driving component 3 is connected to the clamping jaw 12 and is used to control the rotation of the clamping jaw 12, thereby driving the workpiece to rotate, so that the welding torch can remain stationary and complete the circumferential welding of the workpiece.

[0033] Example 2

[0034] like Figure 3 and Figure 4As shown, this embodiment differs from Embodiment 1 in that the gripper 12 includes a connecting seat 4 and a three-jaw chuck disposed on the connecting seat 4. The connecting seat 4 is rotatably connected to the rotating seat 11. Several connecting rods 41 are hinged to the three-jaw chuck, and the connecting rods 41 are evenly arranged around the rotation axis of the three-jaw chuck. A slider 42 is hinged to the end of the connecting rod 41 away from the three-jaw chuck. The slider 42 is slidably disposed on the connecting seat 4, and the sliding direction is parallel to the radial direction of the connecting seat 4. A control component 5 is provided on the connecting seat 4 to control the sliders 42 to move closer to or further away from each other, thereby causing the three-jaw chuck to move closer to or further away from the connecting seat 4.

[0035] like Figure 5 and Figure 6 As shown, the control component 5 includes a rotating disk 51 rotatably connected to the connecting seat 4. The rotating disk 51 is annular, and its central axis is collinear with the rotation axis of the connecting seat 4 on the rotating seat 11. Each slider 42 is provided with a guide groove 52 corresponding to its position on the rotating disk 51, and each slider 42 is provided with a support rod 53 for inserting into the guide groove 52. When the rotating disk 51 rotates, the guide groove 52 pushes the slider 42 to slide radially along the connecting seat 4. Furthermore, a circular driven bevel gear 55 is coaxially arranged on the rotating disk 51, and multiple driving bevel gears 54 are rotatably connected to the rotating disk 51. The driving bevel gears 54 are spaced apart around the circumference of the driven bevel gears 55. The driving bevel gears 54 mesh with the driven bevel gears 55, and driving the driving bevel gears 54 to rotate can drive the rotating disk 51 and the sliders 42 to move synchronously.

[0036] Example 3

[0037] like Figure 7 As shown, this embodiment differs from Embodiment 1 in that, to improve the support stability of the pipe workpiece, a support frame 6 for supporting the workpiece is provided on the base 1. The support frame 6 includes a base plate 61 fixedly connected to the base 1. A pair of support frames 67 are hinged to the base plate 61. Two support frames 67 are provided and symmetrically arranged along the hinge axis of the rotating seat 11. Each support frame 67 is hinged with a support arm 62, and a movable seat 63 is hinged to the end of each support arm 62 away from the support frame 67. Rollers 64 for supporting the workpiece are rotatably connected to each support frame 67. A double-ended stud 65 is rotatably connected to the base plate 61. The axial direction of the double-ended stud 65 is parallel to the hinge axis of the rotating seat 11. The double-ended stud 65 passes through the two movable seats 63 and is threadedly connected to the two movable seats 63. The two movable seats 63 have opposite thread directions corresponding to the double-ended studs 65. When the double-ended studs 65 are rotated, the two movable seats 63 can be moved closer or further apart, thereby adjusting the position and angle of the rollers 64 to accommodate pipe workpieces of different sizes.

[0038] Rollers 64 and support frames 67 are paired one-to-one, and rollers 64 are rotatably connected to the corresponding support frames 67. The central axes of two rollers 64 intersect to form a limiting groove 66 for supporting the pipe workpiece, so as to ensure the stability of the pipe workpiece during rotation.
