Description

Technical Field

[0002] The frame is a framework structure that spans the front and rear axles of the car, commonly known as the beam. It is the base of the car and is generally composed of two longitudinal beams and several cross beams. It is supported on the wheels via the suspension device, the front axle and the rear axle. The frame must have sufficient strength and rigidity to withstand the load of the car and the impact from the wheels.

[0029] Please refer to Figures 1-6 As shown in the figure, the present utility model is a welding device for processing an automotive crossbeam, including a rotating ring 1, on which a fixture mechanism 2, a rotating mechanism 3, and a welding mechanism 4 are provided;

[0030] The fixture mechanism 2 includes a fixture assembly and a spring assembly. The fixture assembly includes two fixture housings 21 fixedly connected to the inner wall of the rotating ring 1. Hydraulic cylinders 22 are fixedly connected to the inner walls of the two fixture housings 21. The output ends of the two hydraulic cylinders 22 are fixedly connected to push cylinders 23. The outer walls of the two push cylinders 23 are slidably connected to the inner walls of the fixture housings 21.

[0031] Among them, as Figure 3 and Figure 5 shown, the spring assembly includes several spring grooves 27 opened on the inner wall of the fixture housing 21.

The several sliders 29 are slidably connected to the inner walls of the spring grooves 27. The several sliders 29 are fixedly connected to the mutually approaching surfaces of the receiving blocks 25.

[0032] By setting the fixture mechanism 2, it is realized that the two clamping blocks 26 are driven by the hydraulic cylinder 22 to clamp and fix the automotive crossbeam component, and the component can be automatically loosened by the elasticity of the spring. The automatic setting does not require manual operation, can quickly clamp and loosen the crossbeam, reduces the time required for replacing components, and improves the efficiency of welding processing.

[0033] Among them, as Figure 2 , Figure 3 and Figure 6As shown in the figure, the rotating mechanism 3 includes a driving component, a linkage component, and a rotating component. The driving component includes a base 31 rotatably connected to the outer wall of the rotating ring 1. The inner bottom wall of the base 31 is fixedly connected to a motor 32. The output end of the motor 32 is fixedly connected to a first rotating shaft 33. The front end of the first rotating shaft 33 extends to the front of the base 31 and is rotatably connected thereto. The front end of the first rotating shaft 33 is fixedly connected to a first pulley 34. The linkage component includes a second rotating shaft 35 rotatably connected to the inner wall of the base 31. The outer wall of the second rotating shaft 35 is fixedly connected to a gear 36. The front end of the second rotating shaft 35 extends to the front of the base 31 and is fixedly connected to a second pulley 37. A belt 38 is sleeved between the second pulley 37 and the first pulley 34. The rotating component includes a plurality of grooves 39 formed on the outer wall of the rotating ring 1. The plurality of grooves 39 are engaged with the gear 36. The inner wall of the base 31 is fixedly connected to two limiting plates 310. The surfaces of the two limiting plates 310 close to each other are rotatably connected to the outer wall of the rotating ring 1.

[0034] By setting the rotating mechanism 3, the rotation of the rotating ring 1 on the base 31 is driven by the motor 32, driving the beam component fixedly clamped by the clamping mechanism 2 to rotate, and cooperating with the welding mechanism 4 to make it more convenient to perform all-round welding processing on the beam.

[0035] Among them, as Figure 1 and Figure 4 shown, the welding mechanism 4 includes a fixing component, a robotic arm component, and a welding component. The fixing component includes a fixing block 41 fixedly connected to the front surface of the rotating ring 1. The robotic arm component includes a large arm rotating joint 42 rotatably connected to the top surface of the fixing block 41. The inner wall of the large arm rotating joint 42 is hinged to a robotic large arm 43. The top end of the robotic large arm 43 is hinged to a robotic small arm 44. The left end of the robotic small arm 44 is fixedly connected to a telescopic arm 45. The front surface of the telescopic arm 45 is hinged to a wrist joint 46.

[0036] By setting the welding mechanism 4, the adjustability and flexibility of the robotic arm are realized, making the welding process more precise than manual welding, and the automated setting saves a large amount of manpower.

[0037] A specific application of this embodiment is as follows: By setting up the fixture mechanism 2, the staff place the crossbeam components on the left and right clamping blocks 26 respectively. After aligning the welding parts in contact, the hydraulic cylinder 22 inside the fixture housing 21 drives the push cylinder 23 to push towards the center of the rotating ring 1. The push cylinder 23 drives the inclined block 24 on it to move. The inclined surface of the inclined block 24 contacts the inclined surfaces on the two receiving blocks 25. The inclined block 24 pushes the receiving blocks 25 to slide towards the center of the fixture housing 21. The two receiving blocks 25 drive the clamping blocks 26 to slide and clamp the components. At this time, the receiving blocks 25 drive the sliders 29 to slide in the spring grooves 27. The sliders 29 slide and compress the springs 28. At this time, the springs 28 are in a compressed state. After the welding mechanism 4 completes the welding process on the automotive crossbeam, the hydraulic cylinder 22 drives the push cylinder 23 to move backward. The springs 28 rebound, driving the two receiving blocks 25 connected to the sliders 29 to move away from each other. The receiving blocks 25 drive the clamping blocks 26 to release the automotive crossbeam, realizing the use of the hydraulic cylinder 22 to drive the two clamping blocks 26 to clamp and fix the automotive crossbeam components. The elastic property of the springs can automatically release the components. The automated setting eliminates the need for manual operation, can quickly clamp and release the crossbeam, reduces the time required for component replacement, and improves the efficiency of the welding process.

[0038] By setting up the rotating mechanism 3, when the fixture mechanism 2 fixes the automotive crossbeam components, in cooperation with the welding mechanism 4, rotating the rotating ring 1 drives the crossbeam components to rotate. The motor 32 drives the first rotating shaft 33 to rotate. The first rotating shaft 33 drives the first pulley 34 to rotate. With the cooperation of the first pulley 34, the belt 38, and the second pulley 37, the first pulley 34 drives the second pulley 37 to rotate synchronously through the belt 38. The second pulley 37 drives the second rotating shaft 35 to rotate. The second rotating shaft 35 drives the gear 36 to rotate. Since the gear 36 meshes with the groove 39 on the rotating ring 1, the gear 36 drives the rotating ring 1 to rotate synchronously on the base 31 through the groove 39. Among them, the limit plate 310 plays a role in limiting the rotating ring 1, realizing the use of the motor 32 to drive the rotating ring 1 to rotate on the base 31, driving the crossbeam components fixedly clamped by the fixture mechanism 2 to rotate, and cooperating with the welding mechanism 4 to make it more convenient to perform all-round welding on the crossbeam.

[0039] By setting up the welding mechanism 4, a fixed block 41 is set to fix the robotic arm assembly. The large arm rotating joint 42 can rotate and turn on the fixed block 41. The robotic large arm 43 and the robotic small arm 44 play a role in supporting and adjusting. The telescopic arm 45 can drive the welding gun 48 to extend the distance. The wrist joint 46 connects the telescopic arm 45 and can drive the connecting block 47 and the welding gun 48 to rotate. The connecting block 47 is used to fix the welding gun 48 on the robotic arm, realizing the use of the adjustability and flexibility of the robotic arm, making the welding process more precise compared to manual welding, and the automated setting saves a large amount of manpower.
