Description

Technical Field

[0001] The present application relates to the technical field of automobile parts welding, and in particular to an automobile spray pipe welding tool. Background Art

[0002] Automobile spray pipe is a key component in the automobile cooling system, ensuring that the automobile can maintain stable performance under high temperature or long-term operation.

[0003] A Chinese patent with publication number CN119115424A discloses a welding tool for a motor spray pipe of a new energy vehicle, including a lifting mechanism, a clamping mechanism, a placement plate and a positioning column. The main pipe of the spray pipe is placed inside the U-shaped hole of the mobile seat, and then the clamping mechanism works to clamp and fix the main pipe, and then the secondary pipe is plugged into the positioning column. After the secondary pipe is plugged and installed, the lifting mechanism descends to drive the mobile seat to move downward, and then drives the main pipe to move closer to the secondary pipe. After the main pipe and the secondary pipe are tightly fitted, the secondary pipe is fixed at this time, which facilitates the subsequent welding work, so that the spray pipe does not need to be manually held by hand to align the through hole of the main pipe during the welding process, thereby reducing the labor intensity of the workers and facilitating the simultaneous welding of multiple secondary pipes on the main pipe, thereby improving work efficiency.

[0004] In the above content, the secondary pipe is vertically welded on the peripheral wall of the main pipe, and the positional relationship between the secondary pipe and the main pipe is adjusted by moving the main pipe. When the main pipe and the secondary pipe are coaxially welded, attention should be paid to the alignment accuracy between the main pipe and the secondary pipe. Once there is an error in the alignment between the main pipe and the secondary pipe, it will cause uneven weld width between the main pipe and the secondary pipe, and even defects such as lack of fusion and lack of penetration will occur, thereby affecting the strength and sealing of the weld. Summary of the invention

[0005] The purpose of this application is to provide a welding tool for an automobile sprinkler pipe, which can ensure the alignment accuracy when welding the main pipe and the auxiliary pipe, thereby improving the strength and sealing of the weld, and is less likely to cause leakage or weld breakage.

[0006] The present application provides a welding tool for an automobile spray pipe, which adopts the following technical solution: A welding tool for an automobile spray pipe, comprising: Body; A spray pipe, which is arranged on the machine body and comprises a main pipe and a secondary pipe; The alignment component is used to adjust the relative position of the main pipeline and the auxiliary pipeline so that the axes of the main pipeline and the auxiliary pipeline are aligned.

[0007] Optionally, the alignment assembly includes a accommodating cylinder, the main pipe and the auxiliary pipe are sleeved on the accommodating cylinder, a plurality of abutment plates are hinged on the outer peripheral wall of the accommodating cylinder, the plurality of abutment plates are evenly distributed on the outer peripheral wall of the accommodating cylinder, and the plurality of abutment plates can move simultaneously along an axial direction perpendicular to the accommodating cylinder.

[0008] Optionally, the alignment assembly also includes a rotating cylinder, the accommodating cylinder is sleeved on the rotating cylinder, one end of the rotating cylinder is fixedly connected to a rotating disk, the rotating disk is provided with a plurality of sliding grooves perpendicular to the axial direction of the accommodating cylinder, and a sliding block is provided at the end of the abutment plate, the sliding block is clamped in the sliding groove and can move along the opening direction of the sliding groove.

[0009] Optionally, a driving assembly is further included, wherein the driving assembly is used to drive the accommodating cylinder to move on the rotating cylinder to drive the abutment plate to move in a direction perpendicular to the axis of the accommodating cylinder.

[0010] Optionally, the driving assembly includes a threaded rod, one end of which is inserted into the rotating cylinder and threadedly connected to the rotating cylinder, the other end of which is fixedly connected to a driving disk, and the end of the accommodating cylinder is rotatably disposed on the driving disk.

[0011] Optionally, a driving source is provided at one end of the rotating cylinder, the driving source is provided at one end of the machine body, and an output end of the driving source is coaxially fixed with the rotating cylinder.

[0012] Optionally, one end of the driving disk facing away from the threaded rod is fixedly connected to an adjusting rod, and the adjusting rod is rotatably arranged at the other end of the machine body.

[0013] Optionally, a detection component is also included, and the detection component is used to detect the porosity at the weld between the main pipeline and the auxiliary pipeline.

[0014] Optionally, the detection component includes a Tesla coil arranged on the machine body, the discharge tip of the Tesla coil is close to the weld, and neon gas is arranged in the spray pipe. When the neon gas can penetrate the pores and approach the discharge tip, the neon gas will release red light.

[0015] In summary, the present application includes at least one of the following beneficial technical effects: 1. Insert the main pipe and the auxiliary pipe on the accommodating cylinder at the same time, rotate the adjusting rod to drive the threaded rod to rotate. Since the driving source controls the rotating cylinder to rotate, when the driving source is in the closed state, the rotating cylinder and the rotating disk are both in a stationary state, and the sliding groove limits the sliding block, so that the abutment plate and the accommodating cylinder will not rotate with the driving disk, and the threaded rod will move in the direction of the rotating disk, and the driving disk will push the accommodating cylinder to move in the direction of the rotating disk, thereby making the sliding block move in the sliding groove in the direction away from the rotating cylinder, driving several abutment plates to move in the direction away from the accommodating cylinder at the same time, until several abutment plates are simultaneously pressed against the inner walls of the main pipe and the auxiliary pipe, thereby fixing the main pipe and the auxiliary pipe synchronously, reducing the situation that shaking is easy to occur when the pipe is fixed manually, resulting in inaccurate alignment of the main pipe and the auxiliary pipe.

[0016] Since the straight-line distances between the plurality of abutment plates and the axis of the receiving tube are equal, the receiving tube is located on the axis lines of the main pipe and the auxiliary pipe at the same time, so that the ends of the main pipe and the auxiliary pipe are aligned, the accuracy of the alignment of the ends of the main pipe and the auxiliary pipe is improved, the width of the weld becomes more uniform, the defects of incomplete fusion and incomplete penetration are reduced, and the strength and sealing of the weld are improved; 2. During the welding process, the driving source can drive the rotating disk and the rotating cylinder to rotate. When the rotating cylinder rotates, the threaded rod and the driving disk will be driven to rotate together, so that the accommodating cylinder is not easy to slide on the rotating cylinder, and then the abutment plate is limited, so that the abutment plate is not easy to move toward the accommodating cylinder. When the rotating disk rotates, the sliding block and the abutment plate will be driven to rotate together, and the friction between the abutment plate and the main pipe and the auxiliary pipe will drive the main pipe and the auxiliary pipe to rotate together at the same time, which is convenient for construction personnel to fully weld the circumferential wall of the welding place, and it is not easy to have a difference in the rotation angle of the main pipe and the auxiliary pipe, resulting in the situation that the welding point just completed is twisted and broken; 3. After welding is completed, neon gas is introduced into the spray pipe and the Tesla coil is started. When there are pores in the weld, the neon gas will pass through the spray pipe from the pores at the top of the spray pipe. When the neon gas is close to the discharge tip, the high-frequency and high-voltage electric field generated by the Tesla coil can excite the electrons in the neon atoms, causing them to transition to a high energy level. When these electrons fall back to a low energy level, they release energy, emitting red visible light to form a red light column, which is convenient for operators to record the position, number and size of the pores in the weld. During the inspection process, the drive source drives the spray pipe to rotate, so that the weld can be fully inspected, further improving the welding quality of the spray pipe.

[0019] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0020] The present application provides a welding tool for automobile spray pipes, referring to Figures 1 to 3 , including a body 1, a positioning component 3, a driving component 4 and a detection component 6, the spray pipe 2 includes a main pipeline 21 and a secondary pipeline 22, and the main pipeline 21 and the secondary pipeline 22 are arranged on the body 1.

[0021] Reference Figure 1 and Figure 2 The alignment component 3 includes a receiving tube 31, the main pipe 21 and the auxiliary pipe 22 are both sleeved on the receiving tube 31, and a plurality of abutment plates 32 are evenly distributed on the outer peripheral wall of the receiving tube 31, and the plurality of abutment plates 32 are all parallel to the axial direction of the receiving tube 31. The plurality of abutment plates 32 can simultaneously move along a direction perpendicular to the axial direction of the receiving tube 31, and are in low contact with the inner walls of the main pipe 21 and the auxiliary pipe 22, so as to play an internal support fixing effect on the main pipe 21 and the auxiliary pipe 22. In this embodiment, four abutment plates 32 are provided, and are evenly distributed around the receiving tube 31. In other embodiments, the abutment plates 32 can be set to any integer greater than two, and the even distribution of the abutment plates 32 can make the abutment plates 32 more evenly affected by the pressure of the spray pipe 2.

[0022] Reference Figure 2 A connecting plate 34 corresponding to the position and number of the abutment plates 32 is fixedly connected to the outer peripheral wall of the accommodating cylinder 31, and a plurality of connecting rods 35 are hinged between the connecting plate 34 and the corresponding abutment plates 32. By rotating the connecting rods 35, the abutment plates 32 can be moved in a direction perpendicular to the axis of the accommodating cylinder 31.

[0023] Reference Figure 2 and Figure 3The alignment component 3 also includes a rotating cylinder 36, the accommodating cylinder 31 is sleeved on the rotating cylinder 36 and can reciprocate along the axial direction of the rotating cylinder 36, the end of the rotating cylinder 36 away from the accommodating cylinder 31 is fixedly connected to a rotating disk 37, and the end of the rotating disk 37 away from the rotating cylinder 36 is provided with a driving source 5, the driving source 5 is a motor, and the driving source 5 is arranged at one end of the body 1, and the output end of the driving source 5 passes through the rotating disk 37 and is coaxially fixed to the rotating cylinder 36.

[0024] Reference Figure 2 and Figure 3 A plurality of sliding grooves 38 perpendicular to the axial direction of the accommodating tube 31 are provided on the rotating disk 37. The number and position of the sliding grooves 38 correspond to the abutment plate 32. A sliding block 33 is fixedly connected to one end of the abutment plate 32. The sliding block 33 is clamped in the sliding groove 38 and can move along the opening direction of the sliding groove 38.

[0025] The main pipe 21 and the auxiliary pipe 22 are inserted into the accommodating cylinder 31 at the same time. When the accommodating cylinder 31 moves toward the rotating disk 37, the sliding block 33 moves in the sliding groove 38 along the direction away from the rotating cylinder 36. The sliding block 33 also drives the abutment plate 32 to move away from the accommodating cylinder 31 until the abutment plate 32 is tightly pressed against the inner walls of the main pipe 21 and the auxiliary pipe 22, thereby fixing the main pipe 21 and the auxiliary pipe 22 synchronously, reducing the shaking that is easy to occur when the pipes are fixed manually, resulting in inaccurate alignment of the main pipe 21 and the auxiliary pipe 22.

[0026] Since the length and rotation angle of the connecting rod 35 are the same, and the straight-line distances between the plurality of abutment plates 32 and the axis of the accommodating tube 31 are equal, the accommodating tube 31 is located on the axial line of the main pipe 21 and the auxiliary pipe 22 at the same time, so that the ends of the main pipe 21 and the auxiliary pipe 22 are aligned, thereby improving the accuracy of the positioning of the ends of the main pipe 21 and the auxiliary pipe 22, making the width of the weld 23 more uniform, reducing the defects of unfusion and incomplete penetration, and improving the strength and sealing of the weld 23.

[0027] Furthermore, the alignment component 3 can fix and align the spray pipes 2 of different sizes, thereby improving the adaptability of the device.

[0028] Reference Figure 3 The driving assembly 4 includes a threaded rod 41, one end of which is inserted into the rotating cylinder 36 and threadedly connected to the rotating cylinder 36, and the other end of the threaded rod 41 is fixedly connected to a driving disk 42. The end of the accommodating cylinder 31 is rotatably set on one side of the driving disk 42, and the side of the driving disk 42 away from the accommodating cylinder 31 is fixedly connected to an adjusting rod 43, and the adjusting rod 43 is set on the side of the body 1 away from the driving source 5.

[0029] When the drive adjustment rod 43 rotates, the driving source 5 controls the rotating cylinder 36 to rotate. When the driving source 5 is in the closed state, the rotating cylinder 36 and the rotating disk 37 are both in the stationary state, and the sliding groove 38 limits the sliding block 33, so that the abutment plate 32 and the receiving cylinder 31 will not rotate with the driving disk 42. Since the rotating cylinder 36 is limited, the threaded rod 41 will move toward the rotating disk 37, and the driving disk 42 will push the receiving cylinder 31 to move toward the rotating disk 37, so that the sliding block 33 moves in the sliding groove 38 away from the rotating cylinder 36, driving the abutment plates 32 to move away from the receiving cylinder 31 at the same time, until the abutment plates 32 are simultaneously pressed against the inner walls of the main pipe 21 and the auxiliary pipe 22, thereby fixing the main pipe 21 and the auxiliary pipe 22 synchronously, reducing the shaking that is easy to occur when the pipe is fixed by manpower, resulting in the inaccurate alignment of the main pipe 21 and the auxiliary pipe 22.

[0030] During the welding process, the driving source 5 can drive the rotating disk 37 and the rotating cylinder 36 to rotate. When the rotating cylinder 36 rotates, it will drive the threaded rod 41 and the driving disk 42 to rotate together, so that the accommodating cylinder 31 is not easy to slide on the rotating cylinder 36, thereby limiting the abutment plate 32, making it difficult for the abutment plate 32 to move toward the accommodating cylinder 31. When the rotating disk 37 rotates, it will drive the sliding block 33 and the abutment plate 32 to rotate together, and the friction between the abutment plate 32 and the main pipe 21 and the auxiliary pipe 22 will simultaneously drive the main pipe 21 and the auxiliary pipe 22 to rotate together, which is convenient for construction personnel to fully weld the circumferential wall of the welding point, and it is not easy for the main pipe 21 and the auxiliary pipe 22 to have a difference in the rotation angle, resulting in the weld just completed being twisted off.

[0031] Reference Figure 1 The detection component 6 includes a Tesla coil 61, which is arranged on the body 1, and the discharge tip 62 of the Tesla coil 61 is located near the weld 23 between the main pipe 21 and the auxiliary pipe 22. Neon gas is continuously filled into the spray pipe 2, so that the air pressure in the spray pipe 2 is greater than the external air pressure. When there are pores in the weld 23 at the top of the spray pipe 2, neon gas will overflow from the pores due to the pressure difference. When the neon gas overflows from a position close to the discharge tip 62, the high-frequency and high-voltage electric field generated by the Tesla coil 61 can excite the electrons in the neon atoms, causing them to transition to a high energy level. When these electrons fall back to a low energy level, they release energy, emit red visible light, and form a red light column, which is convenient for operators to record the pore position, number and size of the weld 23.

[0032] During the detection process, the driving source 5 drives the spray pipe 2 to rotate, so that the weld 23 can be fully detected, the situation of missed detection of the spray pipe 2 is reduced, and the production quality of the spray pipe 2 is ensured.

[0033] The implementation principle of the welding tooling for an automobile sprinkler pipe in an embodiment of the present application is as follows: the main pipe 21 and the auxiliary pipe 22 are sleeved on the accommodating tube 31, and the adjusting rod 43 is rotated to drive the threaded rod 41 to rotate, and the threaded rod 41 moves toward the direction of the rotating disk 37. At the same time, the driving disk 42 pushes the accommodating tube 31 to move in the direction of the rotating disk 37, so that the sliding block 33 moves in the sliding groove 38 in the direction away from the rotating tube 36, driving the plurality of abutment plates 32 to move in the direction away from the accommodating tube 31 at the same time, until the plurality of abutment plates 32 are simultaneously pressed against the inner walls of the main pipe 21 and the auxiliary pipe 22, thereby synchronously fixing the main pipe 21 and the auxiliary pipe 22.

[0034] During welding, the driving source 5 can drive the rotating disk 37 and the rotating cylinder 36 to rotate. When the rotating cylinder 36 rotates, it will drive the threaded rod 41 and the driving disk 42 to rotate together, so that the accommodating cylinder 31 is not easy to slide on the rotating cylinder 36, and then limit the abutment plate 32, so that the abutment plate 32 is not easy to move toward the accommodating cylinder 31. When the rotating disk 37 rotates, it will drive the sliding block 33 and the abutment plate 32 to rotate together, and the friction between the abutment plate 32 and the main pipe 21 and the auxiliary pipe 22 will drive the main pipe 21 and the auxiliary pipe 22 to rotate together, which is convenient for construction personnel to fully weld the circumferential wall of the welding point, and it is not easy for the main pipe 21 and the auxiliary pipe 22 to have a difference in the rotation angle, which will cause the weld just completed to be twisted off.

[0035] After welding is completed, neon gas is continuously filled into the spray pipe 2, the Tesla coil 61 is started, and the starting source is started at the same time, so that the spray pipe 2 is continuously rotated and the rotation speed of the spray pipe 2 is slowed down. Due to the pressure difference, the neon gas will pass through the pores of the weld 23. When the neon gas approaches the discharge tip 62, the high-frequency and high-voltage electric field generated by the Tesla coil 61 can excite the electrons in the neon atoms, causing them to transition to a high energy level. When these electrons fall back to a low energy level, they release energy and emit red visible light to form red light columns. After the spray pipe 2 rotates one circle, the number, position and thickness of the red light columns are recorded, and marked on the weld 23 to facilitate subsequent repair of the pores.

[0036] When the spray pipe 2 rotates one circle and no red light column is found, it is proved that there is no through hole in the weld 23 and the sealing performance of the weld 23 meets the requirements.

[0037] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
