Description

Technical Field

[0001] This utility model relates to the field of copper pipe welding auxiliary tooling technology, and in particular to a copper pipe welding auxiliary device. Background Technology

[0002] In modern industry, copper pipes are widely used in refrigeration, air conditioning, and water pipes due to their excellent thermal conductivity and corrosion resistance. Among these applications, welding is a crucial step in the copper pipe manufacturing process.

[0003] Currently, an existing patent (publication number: CN210147181U) discloses a copper pipe joint welding device. In use, the longitudinal pipe, left branch pipe, and right branch pipe are first assembled into a Y-shaped copper pipe. Then, the assembled Y-shaped copper pipe is fixed on the fixing component of the fixing assembly. The rotating turntable drives the Y-shaped copper pipe to rotate and rotate to the welding assembly. The drive unit B controls the main slide to slide forward, so that the air outlet end of the air pipe is near the joint of each pipe of the Y-shaped copper pipe. The control mechanism A controls the secondary slide to move back and forth, so that the flame end of the air outlet pipe swings back and forth at each joint of the Y-shaped copper pipe to preheat the joint of each pipe of the Y-shaped copper pipe. Then, the welding wire is manually fed into the joint of the pipe to provide welding wire. The welding wire melts under the flame of the air outlet pipe, realizing automatic welding of the joint.

[0004] As can be seen from the above, the aforementioned fixing components are mainly used to assist in copper pipe welding. When the outer diameter of the left branch fitting of the Y-shaped copper pipe is smaller than the inner diameter of the fitting interface of the longitudinal fitting, the interface end face between the left branch fitting and the longitudinal fitting (the upper left end face of the longitudinal fitting) faces upward. Under this condition, copper pipe joint welding can be performed. When the outer diameter of the left branch fitting of the Y-shaped copper pipe is larger than the inner diameter of the fitting interface of the longitudinal fitting, the interface end face between the left branch fitting and the longitudinal fitting (the lower end face of the left branch fitting) faces downward. Under this condition, the Y-shaped copper pipe needs to be rotated 180° so that the downward direction of the interface end face between the left branch fitting and the longitudinal fitting changes to upward before copper pipe joint welding can be performed. However, the aforementioned fixing components for fixing copper tubes cannot rotate the copper tube 180° to change the orientation of the copper tube's interface end face. Therefore, when the interface end face of the copper tube is facing down, the copper tube must be manually removed from the fixing components, the interface end face of the copper tube must be reversed, and then the copper tube must be fixed back to the fixing components. This will result in low welding efficiency and quality of the copper tube. Utility Model Content

[0005] In view of the shortcomings of the existing technology, one of the objectives of this utility model is to provide a copper pipe welding auxiliary device, which can rotate the fixing component for fixing the copper pipe 180° to change the orientation of the copper pipe's interface end face. This eliminates the need to manually remove the copper pipe from the fixing component, readjust the orientation of the copper pipe's interface end face, and then fix the copper pipe back to the fixing component, thereby effectively improving the welding efficiency and quality of the copper pipe.

[0006] To achieve the above objectives, this utility model provides a copper pipe welding auxiliary device, including a mounting bracket, a fixing component, a steering ring, and a limiting magnetic attraction component. The fixing component is used to fix the copper pipe and is rotatably mounted on the mounting bracket. The rotation axis of the fixing component about the mounting bracket is perpendicular to the axial direction of the copper pipe fixed on the fixing component. The steering ring is fixed on the fixing component, and a limiting portion is fixed on the outer ring of the steering ring. The limiting portion extends radially along the steering ring. The limiting magnetic attraction component is fixed on the mounting bracket, and its upper and lower ends are used to stop and magnetically attract the limiting portion, respectively. When the upper end of the limiting magnetic attraction component stops and magnetically attracts the limiting portion, the copper pipe fixed on the fixing component extends vertically upward. When the lower end of the limiting magnetic attraction component stops and magnetically attracts the limiting portion, the copper pipe fixed on the fixing component extends vertically downward.

[0007] Furthermore, the limiting magnetic suction assembly includes a mounting plate and a first limiting member. The mounting plate is fixed on the mounting bracket, and the first limiting member is disposed at the upper end of the mounting plate. The first limiting member is a portion on the upper end of the limiting magnetic suction assembly used to stop the limiting part.

[0008] Furthermore, the limiting magnetic suction assembly also includes a second limiting member, which is disposed at the lower end of the mounting plate. The second limiting member and the first limiting member are symmetrical about the rotation axis of the fixing assembly. The second limiting member is a part on the lower end of the limiting magnetic suction assembly used to stop the limiting part.

[0009] Furthermore, the limiting magnetic attraction assembly also includes a first magnetic attraction member, which is rotatable relative to the fixed assembly. The first magnetic attraction member is a portion on the upper end of the limiting magnetic attraction assembly used to magnetically attract the limiting part.

[0010] Furthermore, the limiting magnetic attraction assembly also includes a second magnetic attraction member, which is rotatable relative to the fixed assembly. The second magnetic attraction member is a portion on the lower end of the limiting magnetic attraction assembly used to magnetically attract the limiting part.

[0011] Furthermore, the fixing assembly includes a fixing base, a telescopic unit, and a clamping plate. The fixing base is rotatably mounted on the mounting bracket and has a mounting groove for mounting the copper tube. The telescopic unit is fixedly mounted on the fixing base, and the telescopic end of the telescopic unit is connected to the clamping plate. The telescopic unit is used to drive the clamping plate to clamp the copper tube mounted on the mounting groove.

[0012] Furthermore, two telescopic units are provided, and the two telescopic units are symmetrical about the rotation axis of the fixed base.

[0013] Furthermore, the clamping plate is provided with a plurality of through holes, which are evenly spaced along the length of the clamping plate.

[0014] Furthermore, the bottom of the mounting groove is provided with support portions on both sides along the length direction of the clamping plate, and the distance between the two support portions forms a positioning distance for positioning the copper tube.

[0015] Furthermore, both the fixed base and the telescopic support are provided with multiple weight-reducing holes.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In use, the copper pipe welding auxiliary device of this utility model fixes the copper pipe to the fixing component. Since the fixing component is rotatably mounted on the mounting bracket, and the rotation axis of the fixing component around the mounting bracket is perpendicular to the axial direction of the copper pipe fixed to the fixing component, the copper pipe can rotate with the fixing component. When the upper end of the limiting magnetic suction component stops the limiting part on the steering ring, and the upper end of the limiting magnetic suction component is magnetically fixed to the limiting part on the steering ring, the copper pipe extends vertically upwards with its interface end facing upwards. At this time, the welder can weld the interface of the copper pipe using welding tools. When the interface end face of the copper pipe is downwards, it is necessary to... When the copper tube is rotated 180° to change the orientation of its interface end face, the fixing component is manually rotated counterclockwise until the limiting part abuts against the lower end of the limiting magnetic component. At this time, the limiting part on the turning ring is magnetically fixed to the lower end of the limiting magnetic component, causing the copper tube to rotate 180°. The copper tube then extends vertically downwards, and the interface end face changes from facing downwards to facing upwards, thus achieving the purpose of changing the orientation of the copper tube's interface end face. There is no need to manually remove the copper tube from the fixing component, readjust the orientation of the copper tube's interface end face, and then fix the copper tube back to the fixing component, thereby effectively improving the welding efficiency and quality of the copper tube.

[0030] Please refer to Figure 1 - Figure 6 This utility model provides a copper pipe 6 welding auxiliary device, including a mounting bracket 1, a fixing component 2, a steering ring 3, and a limiting magnetic suction component 4. The fixing component 2 is rotatably mounted on the mounting bracket 1 and is used to fix the copper pipe 6. The rotation axis of the fixing component 2 around the mounting bracket 1 is perpendicular to the axial direction of the copper pipe 6 fixed on the fixing component 2. The steering ring 3 is fixed on the fixing component 2, and a limiting part 30 is integrally connected to the outer ring of the steering ring 3. The limiting part 30 extends radially along the steering ring 3. The limiting magnetic suction component 4 is fixed on the mounting bracket 1, and its upper and lower ends are used to stop and magnetically attract the limiting part 30, respectively. Specifically, when the upper end of the limiting magnetic suction component 4 stops and magnetically attracts the limiting part 30, the copper pipe 6 fixed on the fixing component 2 extends vertically upward; when the lower end of the limiting magnetic suction component 4 stops and magnetically attracts the limiting part 30, the copper pipe 6 fixed on the fixing component 2 extends vertically downward.

[0031] In use, the copper tube 6 welding auxiliary device of this utility model fixes the copper tube 6 to the fixing component 2. Since the fixing component 2 is rotatably mounted on the mounting bracket 1, and the rotation axis of the fixing component 2 around the mounting bracket 1 is perpendicular to the axial direction of the copper tube 6 fixed on the fixing component 2, the copper tube 6 can rotate with the fixing component 2. When the upper end of the limiting magnetic suction component 4 stops the limiting part 30 on the steering ring 3, and the upper end of the limiting magnetic suction component 4 is magnetically fixed to the limiting part 30 on the steering ring 3, the copper tube 6 extends vertically upward, and the interface end face 60 of the copper tube 6 faces upward (e.g., Figure 5 As shown), at this time, the welder can use welding tools to weld the joint of copper pipe 6; when the joint end face 60 of copper pipe 6 is facing down (as shown), Figure 6As shown, when it is necessary to rotate the copper tube 6 180° to change the orientation of the interface end face 60 of the copper tube 6, the fixing component 2 is manually rotated counterclockwise so that the limiting part 30 rotates to abut against the lower end of the limiting magnetic suction component 4. At this time, the limiting part 30 on the turning ring 3 is magnetically fixed to the lower end of the limiting magnetic suction component 4, so that the copper tube 6 rotates 180°. At this time, the copper tube 6 extends vertically downward, and the interface end face 60 of the copper tube 6 changes from downward to upward, thus achieving the purpose of changing the orientation of the interface end face 60 of the copper tube 6. It is not necessary to manually remove the copper tube 6 from the fixing component 2, readjust the orientation of the interface end face 60 of the copper tube 6, and then fix the copper tube 6 back to the fixing component 2, thereby effectively improving the welding efficiency and quality of the copper tube 6.

[0032] Reference Figure 1 - Figure 3 The fixing component 2 includes a fixing base 20, a telescopic unit 21, and a clamping plate 22. The fixing component 2 is rotatably mounted on the mounting bracket 1 via the fixing base 20, which is rotatably mounted on the mounting bracket 1 via bearings. The fixing base 20 is provided with a mounting groove 201 for mounting the copper tube 6. In this embodiment, the copper tube 6 is a U-shaped copper tube; however, in other embodiments, the copper tube 6 can also be a straight copper tube, and this is not limited here. Furthermore, support portions 202 are provided on both sides of the bottom of the mounting groove 201 along the length direction of the clamping plate 22, and the distance between the two support portions 202 forms a positioning distance for positioning the copper tube 6. That is, when the positioning distance positions the U-shaped copper tube 6, the outer walls of the bottom sides of the U-shaped copper tube 6 abut against the two support portions 202 respectively. In addition, both the fixing base 20 and the telescopic support portions 202 are provided with multiple weight-reducing holes to prevent the fixing component 2 from becoming too heavy.

[0033] Reference Figure 1 - Figure 3 The telescopic unit 21 is fixedly mounted on the fixed base 20, and the telescopic end of the telescopic unit 21 is connected to the clamping plate 22. The telescopic unit 21 is used to drive the clamping plate 22 to clamp the copper tube 6 installed on the mounting groove 201. That is, it can be understood that when one end of the copper tube 6 is placed in the mounting groove 201, the other end of the copper tube 6 extends out of the mounting groove 201. The clamping plate 22 driven by the telescopic unit 21 abuts against the copper tube 6, thereby clamping and fixing the copper tube 6 to the fixed base 20. In order to increase the clamping force of the clamping plate 22 on the copper tube 6, two telescopic units 21 are provided in this embodiment, and the two telescopic units 21 are symmetrical about the rotation axis of the fixed base 20 about the mounting bracket 1. Of course, in other embodiments, three or four telescopic units 21 can also be provided, which is not limited here.

[0034] In addition, the clamping plate 22 is provided with multiple through holes, which are evenly spaced along the length of the clamping plate 22. The through holes are mainly used to reduce the weight of the clamping plate 22.

[0035] In this embodiment, the telescopic unit 21 is a cylinder; of course, in other embodiments, the telescopic unit 21 may also be an electric push rod or a hydraulic cylinder, which is not limited here. Since the telescopic unit 21 in this embodiment is a cylinder, a pneumatic switch 5 for controlling the cylinder is provided at the bottom of the fixed base 20. By providing the pneumatic switch 5, the cylinder can be easily switched on and off, and the user can easily control the start and stop of the cylinder.

[0036] Reference Figure 1 - Figure 4 The limiting magnetic suction assembly 4 includes a mounting plate 40, a first limiting member 41, a second limiting member 42, a first magnetic suction member 43, and a second magnetic suction member 44. Specifically, the mounting plate 40 is sleeved and fixed on the mounting bracket 1, the first limiting member 41 is fixed at the upper end of the mounting plate 40, and the second limiting member 42 is fixed at the lower end of the mounting plate 40. The second limiting member 42 and the first limiting member 41 are symmetrical about the rotation axis of the fixing assembly 2 about the mounting bracket 1. The first limiting member 41 is the part on the upper end of the limiting magnetic suction assembly 4 used to stop the limiting part 30, that is, the first limiting member 41 restricts the degree of freedom of the fixing assembly 2 to rotate clockwise about the mounting bracket 1; the second limiting member 42 is the part on the lower end of the limiting magnetic suction assembly 4 used to stop the limiting part 30, that is, the second limiting member 42 restricts the degree of freedom of the fixing assembly 2 to rotate counterclockwise about the mounting bracket 1.

[0037] Furthermore, the first magnetic chuck 43 is rotatably mounted on the fixed base 20 and positioned above the first limiting member 41, allowing the first magnetic chuck 43 to rotate relative to the fixed assembly 2; the second magnetic chuck 44 is rotatably mounted on the fixed base 20 and positioned above the second limiting member 42, allowing the second magnetic chuck 44 to rotate relative to the fixed assembly 2. Specifically, the first magnetic chuck 43 is the portion on the upper end of the limiting magnetic assembly 4 used to magnetically attract the limiting part 30, that is, it is magnetically fixed to the limiting part 30 of the steering ring 3; the second magnetic chuck 44 is the portion on the lower end of the limiting magnetic assembly 4 used to magnetically attract the limiting part 30. Therefore, by magnetically fixing the first magnetic chuck 43 or the second magnetic chuck to the limiting part 30 of the steering ring 3, the fixed assembly 2 can be fixed after the angle is adjusted.

[0038] Of course, in other embodiments, a first mounting hole can be directly opened on the first limiting member 41 at the position abutting against the limiting part 30, and a first magnet can be installed and fixed in the first mounting hole, that is, the first magnet is the first magnetic suction member 43 described in the above embodiment; similarly, a second mounting hole can be opened on the second limiting member 42 at the position abutting against the limiting part 30, and a second magnet can be installed and fixed in the second mounting hole, that is, the second magnet is the second magnetic suction member 44 described in the above embodiment. With this structure, the upper and lower ends of the limiting magnetic suction assembly 4 can also be magnetically fixed to the limiting part 30 respectively.

[0039] The working principle of the copper tube 6 welding auxiliary device of this utility model is as follows:

[0040] Manually rotate the fixing seat 20 so that the limiting part 30 on the steering ring 3 abuts against the first limiting member 41. At this time, the first magnetic suction member 43 is magnetically fixed to the limiting part 30 on the steering ring 3. Then, place the copper tube 6 to be welded into the mounting groove 201 and make the axis of the copper tube 6 perpendicular to the rotation axis of the fixing seat 20 around the mounting bracket 1. Drive the clamping plate 22 to extend and clamp the copper tube 6 through the telescopic unit 21. If the interface end face 60 of the copper tube 6 is facing upward, there is no need to flip the fixing seat 20. If the interface end face 60 of the copper tube 6 is facing downward, manually rotate the fixing seat 20 counterclockwise so that the limiting part 30 on the steering ring 3 rotates counterclockwise with the fixing seat 20 until it abuts against the second limiting member 42. At this time, the second magnetic suction member 44 is magnetically fixed to the limiting part 30 on the steering ring 3, realizing the 180° flip of the fixing seat 20, thereby realizing the 180° flip of the copper tube 6 and achieving the purpose of changing the orientation of the interface end face 60 of the copper tube 6.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
