Description

Technical Field

[0001] This utility model relates to the field of automotive front tube beam welding technology, and in particular to an auxiliary docking device for welding automotive front tube beams. Background Technology

[0002] In automobile manufacturing, the front tube beam, as a crucial component of the vehicle body structure, undertakes multiple functions, including load-bearing, guidance, and safety protection at the front of the vehicle. Its welding quality directly affects the structural strength and safety performance of the entire vehicle. However, in traditional welding processes, the support structure mostly uses fixed support rollers, lacking flexibility and adaptability. Especially during welding, due to factors such as thermal stress and welding deformation, the tube beam is prone to slight misalignment, leading to problems such as welding misalignment and uneven joints, thus affecting welding quality and assembly accuracy. Therefore, we propose an auxiliary docking device for welding automotive front tube beams to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary docking device for welding automotive front tube beams.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary docking device for welding automotive front tube beams includes a mounting plate. Multiple hexagonal slots are evenly spaced and parallelly arranged at the upper center of the mounting plate. Four hexagonal slots contain a bearing block. Two bearing blocks on the same side form a group, and two bearing blocks in the same group are connected by a reinforcing structure. Two support arms are fixed to both sides of the upper end of each bearing block. Two rubber rollers are rotatably connected between the four support arms on one group of bearing blocks, and two oblique patterned rollers are rotatably connected between the four support arms on the other group of bearing blocks.

[0005] Preferably, the mounting plate has mounting holes at all four corners, and screws are inserted through the mounting holes.

[0006] Preferably, a hexagonal insert is fixed to the lower end of the bearing block, and a magnetic block is fixed to the lower end of the hexagonal insert. The lower ends of the hexagonal insert and the magnetic block are inserted into the hexagonal slot.

[0007] Preferably, the reinforcing structure includes a stud that passes through between two bearing blocks. The bearing blocks have through holes in the middle. The stud passes through two through holes. Four nuts are threaded onto the stud. Two nuts on the same side abut against both sides of a bearing block on the same side.

[0008] Preferably, the load-bearing block and the support arm are integrally formed.

[0009] In this utility model, during welding: 1. Installation preparation: Insert the hexagonal rod at the bottom of the support block into the hexagonal slot on the mounting plate, and use the magnetic block to achieve initial adsorption and fixation; 2. Reinforced connection: Use studs to pass through the through holes in the middle of the two bearing blocks, and tighten two nuts on each side to enhance lateral stability; 3. Support setup: Rubber rollers and oblique patterned rollers installed between the support arms achieve flexible and high-friction support; 4. Welding operation: Place the front tube beam on the support roller, the clamping mechanism at the upper end descends to clamp it, start the welding equipment to carry out the welding operation. Due to the modularity and adjustability of the structure, even if there is slight deformation, it can maintain stability through the adaptive adjustment of the flexible support roller. 5. Disassembly and reuse: After welding, loosen the nuts and pull out the bearing block to facilitate quick replacement or adjustment of the support position. It is suitable for welding tasks of different types of pipe beams.

[0010] This utility model has the following advantages: 1. The device adopts a combination structure of hexagonal slots and plug rods, with magnetic fixation, which allows the bearing block to be quickly disassembled and replaced, and is suitable for the support needs of pipe beams of different sizes, angles and shapes; 2. The use of rubber rollers and oblique patterned rollers can ensure that the pipe beam does not slip or shift during the welding process, and can also maintain stability through the adaptive adjustment of the flexible support roller, thus taking into account both flexibility and anti-slip performance. 3. The transverse reinforcement system composed of studs and nuts effectively prevents the load-bearing block from shifting under welding thermal stress, thus avoiding welding misalignment; 4. The load-bearing block and support arm are made of one piece, which reduces welding points, improves the overall structural strength, and extends the service life of the equipment; In summary, this invention effectively solves the problems of poor stability and adaptability in traditional welding support methods, improves welding quality and efficiency, and can be applied to the support needs of pipe beams of different sizes, angles and shapes. It can ensure that the pipe beam does not slip or shift during the welding process, and can maintain stability through the adaptive adjustment of the flexible support roller, taking into account both flexibility and anti-slip performance, improving the overall structural strength and extending the service life of the equipment.

[0014] Reference Figure 1-5 An auxiliary docking device for welding automotive front tube beams includes a mounting plate 6, which serves as the base platform for the entire device. The mounting plate 6 is made of high-strength steel and has good load-bearing capacity and structural stability. Multiple hexagonal slots 1 are evenly spaced and parallelly arranged at the upper center of the mounting plate 6. Four hexagonal slots 1 are inserted into the bearing blocks 7. Two bearing blocks 7 on the same side form a group. The two bearing blocks 7 in the same group are connected by a reinforcing structure. Two support arms 9 are fixed on both sides of the upper end of the bearing block 7. Two rubber rollers 3 are rotatably connected between the four support arms 9 on one group of bearing blocks 7. The rubber rollers 3 provide flexible support to adapt to slight deformation or curved structure of the pipe beam. The material of the rubber rollers 3 is high-temperature resistant and aging nitrile rubber, which is suitable for high-temperature welding environment. Two oblique patterned rollers 4 are rotatably connected between the four support arms 9 on another set of bearing blocks 7. The oblique patterned rollers 4 provide high friction support to prevent the pipe beam from sliding during welding. The pattern angle of the oblique patterned rollers 4 is 30°-60° according to the friction requirements to enhance the clamping force. Mounting plate 6 has mounting holes 10 at each of its four corners. Screws 5 pass through the mounting holes 10. A hexagonal insert rod 12 is fixed to the lower end of the bearing block 7. A magnetic block 13 is fixed to the lower end of the hexagonal insert rod 12. The magnetic block 13 can be made of permanent magnet material to provide initial attraction force to fix the bearing block 7, which facilitates quick installation and disassembly. The lower ends of the hexagonal insert 12 and the magnetic block 13 are inserted into the hexagonal slot 1. The hexagonal insert 12 is made of stainless steel and has good anti-torsion performance, ensuring that the bearing block 7 will not rotate in the slot. The reinforcement structure includes a stud 2 that runs through the two bearing blocks 7. The stud 2 passes through the through hole 11 of the two bearing blocks 7 and plays a role in lateral connection and stability. The stud 2 is made of a 4.8 grade high-strength bolt. The bearing block 7 has a through hole 11 in the middle. The stud 2 passes through two through holes 11. Four nuts 8 are screwed onto the stud 2. Two nuts 8 on the same side abut against the two sides of a bearing block 7 on the same side. Two nuts 8 are installed at each end of the stud. By tightening, a rigid connection is formed between the bearing blocks 7, which improves the bending and torsional resistance of the overall structure. The nuts 8 are equipped with spring washers to prevent loosening caused by welding vibration. The load-bearing block 7 and the support arm 9 are integrally formed, which has high structural strength and dimensional stability.

[0015] In this utility model, during welding: 1. Installation preparation: Insert the hexagonal insert 12 at the bottom of the support block 7 into the hexagonal slot 1 on the mounting plate 6, and achieve initial adsorption and fixation through the magnetic block 13; 2. Reinforced connection: Use studs 2 to pass through the through holes 11 in the middle of the two bearing blocks, and tighten two nuts 8 on each side to enhance lateral stability; 3.
