[0003] When welding the inlet and outlet pipe assembly, since multi-section fixing and simultaneous welding are carried out, in order to prevent the influence of external vibration on the welding process, the fixing parts of the inlet and outlet pipe assembly are usually in a fixed state. However, the welding point positions of the inlet and outlet pipe assembly are complex, and a single welding fixing structure cannot complete the welding process. Some welding points require the attitude of the inlet and outlet pipe assembly to be adjusted to an inclined state before welding can be carried out. It is necessary to replace the fixing parts of the inlet and outlet pipe assembly to achieve the purpose of adjusting the attitude of the inlet and outlet pipe assembly, so that other welding points of the inlet and outlet pipe assembly become easy-to-weld points. The process requires continuous adjustment, which is time-consuming and laborious and reduces work efficiency; after the welding of the inlet and outlet pipe support is completed, due to the use of multiple fixing parts, the inlet and outlet pipe assembly is easily blocked by the fixing parts during unloading, and the inlet and outlet pipe assembly is easily in contact with the fixing parts during unloading, resulting in scratches and reducing the quality.

[0016] The present invention also discloses a welding method for processing an automobile inlet and outlet pipe assembly, which uses the above welding device and includes the following steps:

[0017] Before welding, the first fixing component clamps and fixes one section of the inlet and outlet pipe, and the second fixing component clamps and fixes the other section of the inlet and outlet pipe. The fixed clamping plates move towards each other to clamp and fix the filter pipe located between the fixed clamping plates. The first fixing component moves so that the inlet and outlet pipe clamped by the first fixing component abuts against the filter pipe. The second fixing component moves so that the inlet and outlet pipe of the second fixing component abuts against the filter pipe.

[0018] During welding, the welding head located above the equipment welds the abutting part of the inlet and outlet pipe and the filter pipe. After the welding at the welding point at the top of the abutting part of the inlet and outlet pipe and the filter pipe is completed, the first fixing component and the second fixing component rotate to drive the inlet and outlet pipes they hold to rotate. While the first fixing component and the second fixing component are rotating, the rotation of the rotating gear enables the sliding mounting block to slide along the inner wall of the supporting ring plate. The sliding mounting block drives the fixed clamping plate to rotate, and the fixed clamping plate drives the filter pipe to rotate, so that the inlet and outlet pipe and the filter pipe rotate synchronously, and the welding points on both sides and at the bottom of the abutting part of the inlet and outlet pipe and the filter pipe are successively rotated to the top, facilitating the welding head to complete the welding;

[0019] After welding is completed, the first fixing component and the second fixing component release the fixation of the inlet and outlet pipe. The supporting ring plate rotates, moving the two ends of the inlet and outlet pipe away from the first fixing component and the second fixing component. The fixed clamping plate releases the contact with the filter pipe, and the assembled inlet and outlet pipe after welding of the inlet and outlet pipe and the filter pipe is unloaded.

[0020] Beneficial effects

[0021] Compared with the prior art, the present invention provides a welding device and a welding method for processing an assembled inlet and outlet pipe for an automobile, having the following beneficial effects:

[0022] 1. After the welding at the welding point at the top of the abutting part of the inlet and outlet pipe and the filter pipe is completed, the first fixing component and the second fixing component rotate to drive the inlet and outlet pipes they hold to rotate. While the first fixing component and the second fixing component are rotating, the rotation of the rotating gear enables the sliding mounting block to slide along the inner wall of the supporting ring plate. The sliding mounting block drives the fixed clamping plate to rotate, and the fixed clamping plate drives the filter pipe to rotate, so that the inlet and outlet pipe and the filter pipe rotate synchronously, and the welding points on both sides and at the bottom of the abutting part of the inlet and outlet pipe and the filter pipe are successively rotated to the top, facilitating the welding head to complete the welding; During the welding process, the inlet and outlet pipe and the filter pipe can be continuously rotated synchronously and the posture can be adjusted, reducing the welding difficulty of welding points at different positions, avoiding changing the fixed posture of the inlet and outlet pipe and the filter pipe to replace different fixing parts in order to reduce the welding difficulty of different welding points, reducing the steps of replacing fixing parts, and improving work efficiency.

[0023] 2. After welding is completed, the first fixing component and the second fixing component release the fixation of the inlet and outlet pipe. The supporting ring plate rotates, moving the inlet and outlet pipe away from the first fixing component and the second fixing component. The fixed clamping plate releases the contact with the filter pipe, and the assembled inlet and outlet pipe after welding of the inlet and outlet pipe and the filter pipe is unloaded; Changing the unloading position of the assembled inlet and outlet pipe prevents the first fixing component and the second fixing component from affecting unloading, facilitating unloading, and improving work efficiency.

[0024] 3. Place the heavier inlet and outlet pipes on the fixed clamping plate, rotate the fixed motor to drive the rotating clamping plate to rotate, and the rotating clamping plate and the fixed clamping plate initially fix the inlet and outlet pipes. The clamping motor drives the clamping screw rod to rotate, and the rotation of the clamping screw rod drives the rotating mounting block to move towards the fixed mounting block. The rotating clamping plate at the top of the rotating mounting block moves towards the fixed clamping plate to fix the inlet and outlet pipes; perform secondary fixation on the heavier inlet and outlet pipes to prevent the heavier inlet and outlet pipes from shifting due to their own gravity during welding, resulting in unqualified welding of the inlet and outlet pipe assembly.

[0025] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Next, the technical solutions in the embodiments of the invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the invention.

[0040] In the description of the present invention, it should be understood that the terms "openings", "upper", "lower", "top", "middle", "inner", etc. indicating orientations or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.

[0041] Example 1, please refer to Figures 1 - 10 As shown, the present invention discloses a welding device, including a welding table 1, a fixed rotation assembly 2, a first fixing assembly 3, and a second fixing assembly 4. The first fixing assembly 3, the fixed rotation assembly 2, and the second fixing assembly 4 are sequentially arranged on the top surface of the welding table 1;

[0042] The fixed rotating assembly 2 includes a support ring plate 201, a sliding mounting block 202, a fixed gear ring 203, a rotating gear 204, and two fixed clamping plates 205. The support ring plate 201 is vertically arranged on the top surface of the welding table 1. The sliding mounting block 202 is slidably mounted on the inner wall of the support ring plate 201. The fixed gear ring 203 is fixedly mounted on one side of the support ring plate 201. The rotating gear 204 is rotatably mounted on the side of the sliding mounting block 202 close to the fixed gear ring 203. The rotating gear 204 meshes with the fixed gear ring 203. The fixed clamping plates 205 are both slidably mounted at one end of the sliding mounting block 202 away from the support ring plate 201.

[0043] The fixed clamping plates 205 are used for clamping the filter gas pipe. The first fixing component 3 and the second fixing component 4 are respectively used for clamping the inlet and outlet pipes and abutting the inlet and outlet pipes against both ends of the filter gas pipe. The circumferential area at the abutting joint of the inlet and outlet pipes and the filter gas pipe is the welding point. The first fixing component 3 and the second fixing component 4 can drive the inlet and outlet pipes to rotate. The rotating gear 204 can drive the filter gas pipe to rotate. The inlet and outlet pipes and the filter gas pipe rotate synchronously. The welding head is used to weld the welding points rotated to the surface facing up in sequence to form the inlet and outlet pipe assembly.

[0044] During use, place the filter gas pipe between the fixed clamping plates 205. The fixed clamping plates 205 move towards each other to clamp and fix the filter gas pipe. The first fixing component 3 clamps and fixes one section of the inlet and outlet pipe, and the second fixing component 4 clamps and fixes the other section of the inlet and outlet pipe. The first fixing component 3 moves so that the inlet and outlet pipe clamped by the first fixing component 3 remains in contact with the filter gas pipe. The second fixing component 4 moves so that the inlet and outlet pipe of the second fixing component 4 remains in contact with the filter gas pipe. The welding head located above the equipment welds the contact area between the inlet and outlet pipe and the filter gas pipe. When the welding at the welding point at the top of the contact area between the inlet and outlet pipe and the filter gas pipe is completed, the first fixing component 3 and the second fixing component 4 rotate to drive the respective clamped inlet and outlet pipes to rotate. While the first fixing component 3 and the second fixing component 4 are rotating, the rotating gear 204 rotates itself. Under the meshing action of the rotating gear 204 and the fixed gear ring 203, the rotating gear 204 makes a circular motion along the fixed gear ring 203, that is, rotates around the central axis of the fixed gear ring 203. As a result, the sliding mounting block 202 slides along the inner wall of the support ring plate 201. The sliding mounting block 202 drives the fixed clamping plate 205 to rotate, and the fixed clamping plate 205 drives the filter gas pipe to rotate, so that the inlet and outlet pipe and the filter gas pipe rotate synchronously. The welding points are sequentially rotated upwards. A welding mechanism (not shown in the figure) is provided on the welding table 1. The welding head of the welding mechanism can perform three-dimensional movement to realize the welding of the welding head to the welding point directly below it. During the welding process, the inlet and outlet pipe and the filter gas pipe can be continuously rotated synchronously and the posture can be adjusted, reducing the welding difficulty of welding points at different positions, avoiding changing the fixed posture of the inlet and outlet pipe and the filter gas pipe to replace different fixing parts to reduce the welding difficulty of different welding points, reducing the steps of replacing fixing parts, and improving work efficiency. After the welding is completed, the first fixing component 3 and the second fixing component 4 release the fixation of the inlet and outlet pipe. The support ring plate 201 rotates to move the inlet and outlet pipe away from the first fixing component 3 and the second fixing component 4. The fixed clamping plate 205 releases the contact with the filter gas pipe, and the inlet and outlet pipe assembly with the inlet and outlet pipe and the filter gas pipe welded is unloaded. Changing the unloading position of the inlet and outlet pipe assembly prevents the first fixing component 3 and the second fixing component 4 from affecting the unloading, facilitates the unloading, and improves work efficiency.

[0045] Embodiment 2 is different from the above embodiment. Please refer to Figure 3 、 Figure 5 、 Figure 6, the fixed rotation assembly 2 further includes a fixed lead screw 206, a fixed motor 207, a rotating mounting frame 208, and a rotating motor 209. An annular special-shaped groove is formed in the inner wall of the support ring plate 201. A rotating slider is slidably mounted in the annular special-shaped groove, and the annular special-shaped groove limits the rotating slider so that the rotating slider can only slide along a circular track in the annular special-shaped groove and cannot move radially along the support ring plate 201. The rotating slider is fixedly connected to the sliding mounting block 202. A lead screw mounting groove is formed at one end of the sliding mounting block 202 away from the support ring plate 201. The fixed lead screw 206 is rotatably mounted in the lead screw mounting groove. The fixed motor 207 is fixedly mounted at one end of the sliding mounting block 202. The drive shaft of the fixed motor 207 passes through the sliding mounting block 202 and is fixedly connected to the fixed lead screw 206. Two sliding blocks are helically sleeved on the fixed lead screw 206. The sliding blocks are slidably matched with the lead screw mounting groove. The bottom ends of the sliding blocks are respectively fixedly connected to the fixed clamping plates 205. The rotating mounting frame 208 is arranged on the side of the sliding mounting block 202 close to the rotating gear 204. The rotating mounting frame 208 is fixedly connected to the sliding mounting block 202 and the rotating gear 204 is located inside the rotating mounting frame 208. The rotating motor 209 is fixedly mounted on the side of the rotating mounting frame 208 away from the rotating gear 204. The drive shaft of the rotating motor 209 passes through the rotating mounting frame 208 and is fixedly connected to the rotating gear 204;

[0046] During use, when fixing the filter gas pipe, the fixed motor 207 drives the fixed lead screw 206 to rotate. The fixed lead screw 206 is a double-threaded lead screw. The rotation of the fixed lead screw 206 drives the fixed clamping plates 205 to move towards each other to fix the filter gas pipe; the rotating motor 209 drives the rotating gear 204 to rotate. The rotation of the rotating gear 204 can make the sliding mounting block 202 move along the inner wall of the support ring plate 201. The movement of the sliding mounting block 202 drives the fixed clamping plate 205 to rotate around the central axis of the support ring plate 201, and the fixed clamping plate 205 drives the filter gas pipe to rotate.

[0047] Embodiment 3 is different from the above embodiment. Please refer to Figure 3, the fixed rotating assembly 2 further includes a rotating circular plate 210, a rotating mounting plate 211, a driving cylinder 212, a circular plate connecting block 213, a cylinder mounting block 214, and a pushing electric push rod 215.

A rotating mounting groove is formed on the top surface of the rotating mounting plate 211, and the rotating circular plate 210 is rotatably mounted in the rotating mounting groove. The bottom end of the support ring plate 201 is fixedly mounted on the top surface of the rotating circular plate 210. The cylinder mounting block 214 is rotatably mounted on the top surface of the rotating mounting plate 211. The circular plate connecting block 213 is rotatably mounted on the top surface of the rotating circular plate 210.

A moving connecting plate is fixedly mounted on the top surface of the rotating mounting plate 211, and the output end of the pushing electric push rod 215 is fixedly connected to the moving connecting plate;

[0048] During use, the push rod of the driving cylinder 212 extends, pushing the circular plate connecting block 213 to move. The movement of the circular plate connecting block 213 drives the rotating circular plate 210 to rotate. The rotating circular plate 210 drives the support ring plate 201 to rotate. When the push rod of the driving cylinder 212 extends to the farthest position, the side surface of the support ring plate 201 is parallel to the side surface of the welding table 1 at this time. When the push rod of the driving cylinder 212 contracts to the nearest position, the side surface of the support ring plate 201 is perpendicular to the side surface of the welding table 1 at this time. The rotation of the support ring plate 201 drives the inlet and outlet pipe assembly to rotate, so that there are no obstructive parts in the discharging direction of the inlet and outlet pipe assembly; when the lengths of the two sections of the inlet and outlet pipes change, the position of the filter gas pipe in contact with the inlet and outlet pipes needs to change. The pushing electric push rod 215 drives the rotating mounting plate 211 to move, and can fix the filter gas pipes at different positions with the fixed clamping plate 205.

The fixed support plate 301 is slidably mounted on the top surface of the welding table 1. The lead screw mounting block 304 is rotatably mounted on one side of the fixed support plate 301 close to the support ring plate 201. The fixed mounting block 302 is fixedly connected to the lead screw mounting block 304. The fixed clamping plate 303 is fixedly mounted at one end of the fixed mounting block 302 away from the fixed support plate 301.

[0050] During use, place the heavier inlet and outlet pipe on the fixed clamping plate 303. The rotating fixing motor 309 drives the rotating clamping plate 308 to rotate. The rotating clamping plate 308 and the fixed clamping plate 303 initially fix the inlet and outlet pipe. The clamping motor 306 drives the clamping lead screw 305 to rotate. The rotation of the clamping lead screw 305 drives the rotating mounting block 307 to move towards the fixed mounting block 302.

[0061] The present invention also discloses a welding method for processing an automobile inlet and outlet pipe assembly, using the above welding device, including the following steps:

[0062] Before welding, the first fixing component 3 clamps and fixes one section of the inlet and outlet pipe, the second fixing component 4 clamps and fixes the other section of the inlet and outlet pipe, the fixed clamping plates 205 move towards each other to clamp and fix the air filter pipe located between the fixed clamping plates 205, the first fixing component 3 moves so that the inlet and outlet pipe clamped by the first fixing component 3 is in contact with the air filter pipe, and the second fixing component 4 moves so that the inlet and outlet pipe of the second fixing component 4 is in contact with the air filter pipe.

[0063] During welding, the welding head above the equipment welds the contact area between the inlet and outlet pipe and the air filter pipe. When the welding point at the top of the contact area between the inlet and outlet pipe and the air filter pipe is welded, the first fixing component 3 and the second fixing component 4 rotate to drive the inlet and outlet pipes they clamp to rotate. While the first fixing component 3 and the second fixing component 4 are rotating, the rotating gear 204 rotates to enable the sliding mounting block 202 to slide along the inner wall of the support ring plate 201. The sliding mounting block 202 drives the fixed clamping plate 205 to rotate, and the fixed clamping plate 205 drives the air filter pipe to rotate, so that the inlet and outlet pipe and the air filter pipe rotate synchronously, and the welding areas on both sides and the bottom of the contact area between the inlet and outlet pipe and the air filter pipe are successively rotated to the top, facilitating the welding head to complete the welding.

[0064] After welding is completed, the first fixing component 3 and the second fixing component 4 release the fixation of the inlet and outlet pipes, the support ring plate 201 rotates to move the two ends of the inlet and outlet pipes away from the first fixing component 3 and the second fixing component 4, the fixed clamping plate 205 releases the contact with the air filter pipe, and the inlet and outlet pipe assembly with the inlet and outlet pipe and the air filter pipe welded is unloaded.
