Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a diesel engine exhaust manifold welding device. Background Art

[0002] The exhaust manifold is connected to the cylinder block of the diesel engine, and collects the exhaust of each cylinder into the exhaust manifold, and then enters the branched pipe and is discharged. The main requirement for it is to minimize the exhaust resistance and avoid mutual interference between the cylinders. Therefore, the exhaust manifolds of existing diesel engines are mostly strange in shape. Therefore, when welding the exhaust manifold, it is necessary not only to adjust the angle or direction of the exhaust manifold of the diesel engine, but also to stabilize the exhaust manifold. Therefore, the following problems will occur when welding the exhaust manifold of the diesel engine:

[0003] During welding, it is necessary to manually hold an arc welding gun to weld the exhaust manifold in a full circle. During the holding process, it is easy for a leak to occur when the welding gun moves to the bottom of the exhaust manifold. Therefore, the exhaust manifold needs to be turned over during welding to ensure that the exhaust manifold is welded in a full circle. However, during this process, the metal between the welds has not been completely cooled, and the welding position is easily deformed due to the turning. At the same time, its position changes after turning over, and the exhaust manifold is special-shaped. After turning over the position of the exhaust manifold, it will be squeezed with the ground or the supporting bracket, which will further cause extrusion deformation at the welding position. At the same time, in the process of turning over the exhaust manifold, the instability of the handheld arc welding gun is easy to cause misalignment and offset between the welds, which will lead to welding deviations.

[0004] In order to solve the above problems, the inventor proposed a diesel engine exhaust manifold welding device, which has the advantages of stable full-circle welding and stable flipping. Summary of the invention

[0041] Further, such as Figure 1 , Figure 8 and Fig. 9As shown, a support assembly for supporting the exhaust manifold is provided on the inner ring 3, and the support assembly includes a third swivel 61 rotatably connected to the frame 2, and a support rod 1 62 is fixedly connected to the third swivel 61, and the support rod 1 62 is set to a telescopic structure. The end of the support rod 1 62 away from the third swivel 61 is hinged with a support rod 2 63, and a fastener is provided at the hinge of the support rod 1 62 and the support rod 2 63.

After the two support rings 65 are combined, they are adapted to the shape of the connecting port of the exhaust manifold 57. The inner ring wall of the support ring 65 is set to rubber material, and the rubber material of the support ring 65 is used to prevent the clamping exhaust manifold from sliding. The support rod three 64 is symmetrically provided with push grooves 66, and the inside of the push grooves 66 is fixedly connected with a spring 67.

The limit pad 69 is made of rubber material and can increase friction. The limit pad 69 is used to resist the support ring 65 to prevent the support ring 65 from unfolding.

[0042] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments:

[0043] The initial state is: since the elastic force of the torsion springs on both sides of the support ring 65 is greater than the elastic force of the spring 67, the two support rings 65 are initially in a state of being away from each other, and the magnetic blocks at both ends are not in the magnetic attraction range, so the push-fit block 68 is in a state of being squeezed by the support ring 65, the spring 67 is also in a squeezed state, and the limit pad 69 inside the push-fit block 68 does not conflict with the support ring 65.

[0044] The working status is:

[0045] The stabilizing component adjusts and fixes the position of the exhaust manifold 57:

[0046] like Figure 2 and Figure 7As shown, the user fixes the exhaust manifold 57 on the fixing frame 54. When the tightening knob 55 is rotated clockwise in the threaded hole on the fixing frame 54, the tightening knob 55 will not fit tightly with the slide plate 56, so that the slide plate 56 has space to move. At this time, the slide plate 56 is no longer tightly fitted with the rotating frame 52. The user manually adjusts the position of the slide plate 56 so that the slide plate 56 slides on the rotating frame 52. The slide plate 56 drives the fixing frame 54 to slide on the slide groove 53 through the tightening knob 55, and the fixing frame 54 drives the exhaust manifold 57 to move. At this time, the connection port of the exhaust manifold 57 welded to the exhaust manifold is adjusted to a position that coincides with the center position of the inner ring 3. When the exhaust After the connection port of the exhaust manifold 57 is adjusted to a position that coincides with the center of the inner ring 3, the user manually tightens the tightening knob 55 counterclockwise to make the slide plate 56 close to the rotating frame 52. At this time, the fixing frame 54 is positioned on the rotating frame 52 under the action of the tightening knob 55. If it is necessary to adjust the direction of the exhaust manifold 57, the rotating frame 52 is manually rotated, and the rotating frame 52 drives the second rotating ring 51 to rotate on the inner ring 3, and the rotating frame 52 drives the fixing frame 54 to rotate, and the fixing frame 54 drives the exhaust manifold 57 to rotate, thereby realizing the position adjustment of the exhaust manifold 57, and realizing the adjustment of the position at different angles and in different directions for subsequent welding operations.

[0047] The support assembly supports the exhaust manifold:

[0048] like Figure 1 , Figure 8 and Fig. 9As shown, the user places the exhaust manifold between the two support rings 65, and then manually pushes the paddle on the push-fit block 68 to make the push-fit block 68 slide on the support rod 3 64 to one side of the support ring 65. After continuing to move, the push-fit block 68 will contact the support ring 65, so that the support ring 65 converges in the middle with the hinge point with the support rod 3 64 as the axis. At this time, the torsion springs on both sides of the support ring 65 are deformed. When the support ring 65 is closed, the two magnetic blocks on it will be opposite in magnetic poles, and according to the principle of opposite magnetic fields attracting each other, the two support rings After the push-fit block 68 is closed, they will be magnetically attracted to each other. At the same time, after the push-fit block 68 continues to move to one side of the support ring 65, the limit pad 69 in the push-fit block 68 will contact one end of the hinge point between the support ring 65 and the support rod three 64, and then squeeze the hinge point end of the support ring 65 and the support rod three 64. At the same time, the elastic stretching action of the spring 67 makes the limit pad 69 in the push-fit block 68 always squeeze the support ring 65 to prevent the push-fit block 68 from being separated from the squeeze relationship with the support ring 65. At this time, the squeeze of the limit pad 69 and the adsorption force of the magnetic block make The support ring 65 cannot be unfolded. At this time, the support ring 65 is closed to fix the exhaust manifold. At the same time, because the inner ring surface of the support ring 65 is provided with a rubber soft material, it can prevent sliding after the exhaust manifold is clamped and fixed. If it is necessary to support exhaust manifolds of different shapes, the third rotating ring 61 can be rotated to rotate on the inner ring 3. The third rotating ring 61 drives the structure thereon to rotate, and the fasteners between the support rod 1 62 and the support rod 2 63 are rotated to loosen the angle between the support rod 1 62 and the support rod 2 63. Manual adjustment, and then loosen the fasteners between support rod two 63 and support rod three 64, so that the angle between support rod two 63 and support rod three 63 can be adjusted. At the same time, support rod one 62 is a telescopic structure, so that the angle and position of the exhaust manifold clamped and fixed by the support ring 65 can be adjusted. When the exhaust manifold is adjusted to coincide with the connection position of the exhaust main pipe 57, the above-mentioned fasteners are tightened after the adjustment is completed, so as to adapt to the positioning adjustment of exhaust manifolds of different shapes, and at the same time, it can also ensure stable support for the exhaust manifold during welding.

[0049] Stabilizing welding components to adjust welding position:

[0050] like Figure 5As shown, the user loosens the fasteners at the hinge point of stabilizer bar 1 47 and stabilizer bar 2 48, and the angle between stabilizer bar 2 48 and stabilizer bar 1 47 can be adjusted, and then the fasteners at the hinge point of stabilizer bar 2 48 and stabilizer bar 3 49 can be loosened, and the angle between stabilizer bar 3 49 and stabilizer bar 2 48 can be adjusted. During the adjustment of stabilizer bar 3 49, stabilizer bar 3 49 will also drive welding gun 410 to move synchronously. At the same time, support rod 1 62 is a telescopic structure, and the distance between welding gun 410 and the weld to be welded can be adjusted. After the position of welding gun 410 is adjusted, the fasteners between stabilizer bar 1 47 and stabilizer bar 2 48 are tightened again to fix the angle between stabilizer bar 1 47 and stabilizer bar 2 48, and then the fasteners between stabilizer bar 2 48 and stabilizer bar 3 49 are tightened to fix the angle between stabilizer bar 2 48 and stabilizer bar 3 49. At this time, the welding direction of welding gun 410 is aligned with the gap between exhaust main pipe 57 and exhaust manifold.

[0051] Stable welding assembly for welding exhaust manifold 57 and exhaust manifold:

[0052] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, at this time, the user starts the welding gun 410, so that the welding gun 410 welds the gap between the exhaust main pipe 57 and the exhaust manifold. During the welding process of the welding gun 410, the user manually rotates the first rotating ring 42, so that the first rotating ring 42 slides inside the rotating groove 41. At this time, the ball 43 between the first rotating ring 42 and the rotating groove 41 assists the first rotating ring 42 to slide stably and smoothly. During the sliding process, the first rotating ring 42 drives the rotating shaft 45 to rotate synchronously, and the rotating shaft 45 drives the stabilizing bar 1 47 to rotate synchronously. The stabilizing bar 1 47 makes the stabilizing bar 2 48 drive the welding gun 410 to rotate synchronously through the stabilizing bar 3 49. The rotation of the welding gun 410 The kinetic energy can weld the connection port of the exhaust main pipe 57 and the exhaust manifold. At the same time, during the rotation of the rotating shaft 45, the guide rod 46 always slides inside the stabilizing groove 416. Under the guiding effect of the stabilizing groove 416, the guide rod 46 drives the rotating shaft 45 to rotate on the fixed shaft 44. The rotation of the rotating shaft 45 on the fixed shaft 44 will drive the stabilizing rod 1 47 to rotate synchronously. The stabilizing rod 1 47 enables the stabilizing rod 3 49 to always align the welding gun 410 with the weld through the stabilizing rod 2 48, thereby ensuring the stability of welding, improving the fluency of welding, and improving the adaptability of welding by welding welds at different angles.

[0053] The welding stabilization component cleans the residual debris at the welding position:

[0054] like Figure 2 , Figure 4 and Figure 5As shown, since the interference wheel 412 can fit with the surface of the exhaust manifold 57 connection port, when the above-mentioned exhaust manifold and the exhaust manifold 57 overlap, the interference wheel 412 can also fit with the surface of the exhaust manifold. When the above-mentioned stabilizer bar 3 49 rotates, the stabilizer bar 3 49 drives the interference wheel 412 to roll on the exhaust manifold surface through the gear shaft 411. During the rolling of the interference wheel 412, the gear shaft 411 can be driven to rotate. The gear shaft 411 can drive the reverse gear 414 to rotate through the gear thereon. The reverse gear 414 drives the cleaning roller 415 to rotate through the transmission shaft 413. At this time, the cleaning roller 415 can clean the welding slag around the weld to avoid excessive accumulation of welding slag and affecting the flatness around the weld. It can further ensure the welding stability of the connection port between the exhaust manifold and the exhaust manifold 57 and avoid the problem of loose welding.
