Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding device for processing automobile exhaust pipes. Background Technology

[0002] The car exhaust pipe, also known as the car exhaust hose, is part of the car engine's exhaust system. The exhaust system mainly includes the exhaust manifold, exhaust pipe, and muffler. The car exhaust pipe is used to vent the exhaust gas left after the engine runs to the outside of the car. Its main material is stainless steel SUS304. The car exhaust pipe requires welding equipment during the processing to connect two or more exhaust pipe sections.

[0003] Existing automotive exhaust pipe welding equipment typically involves fixing two exhaust pipes separately using clamps on both sides of the machine body. Then, a transmission rail drives the two clamps and exhaust pipes to move in opposite directions. When the two exhaust pipes reach a position where they are in contact with each other, the motors on both sides simultaneously drive the clamps and exhaust pipes to rotate. Then, a welding torch is used to heat-melt the welding wire and integrate it into the gap where the two exhaust pipes are in contact, thus achieving the welding process for the two exhaust pipes.

[0004] However, because the welding torch is at a high temperature when it enters the gap after welding the two exhaust pipes, the welding wire solution may require a long cooling time, resulting in a slow welding forming speed of the exhaust pipes and affecting the welding processing efficiency of the exhaust pipes. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a welding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a welding device for processing automobile exhaust pipes, comprising a body, a welding torch disposed on one side of the body, a transmission rail disposed on one side of the body, a motor disposed on one side of the transmission rail, a clamp disposed at the output end of the motor, a cooling device disposed on one side of the body, and a support device disposed at the bottom of the body. The cooling device includes a support frame, which is fixedly connected to the body. A circular hole is opened on one side of the support frame, a positioning rod is slidably connected to the inner wall of the circular hole, a wind duct is slidably connected to the inner wall of the support frame, multiple air nozzles are fixedly connected to the inner side of the wind duct, a fan is fixedly connected to one side of the wind duct, the output end of the fan is connected to the inner wall of the wind duct, a through hole is opened on one side of the wind duct, and the surface size and shape of the positioning rod are adapted to the size and shape of the inner wall of the through hole.

[0007] The effect achieved by the above components is as follows: By setting up a cooling device, the air duct is first manually moved, causing the air duct to drive the fan. When the air duct moves to the position inside the support frame, the inner wall of the through hole coincides with the inner wall of the circular hole. At this time, the positioning rod is manually moved. When the positioning rod moves to the position where it is fully inserted into the circular hole and the through hole, the positioning rod is positioned inside the circular hole and the through hole to fix the air duct in place, achieving rapid assembly of the air duct and the support frame. At this time, the two exhaust pipes are fixed by clamps on both sides of the machine body. Then, the transmission rail drives the two clamps and exhaust pipes to move in opposite directions. When the two exhaust pipes move to the position where they are in contact with each other, the two exhaust pipes... The joint of the two exhaust pipes is located inside the air duct. At this time, the motors on both sides drive the two clamps and the two exhaust pipes to rotate simultaneously. Then, the welding torch is used to melt the welding wire and integrate it into the gap between the joints of the two exhaust pipes, thus achieving the welding process of the two exhaust pipes. At this time, the fan is started, which delivers airflow into the air duct. The airflow is discharged through multiple nozzles and blown onto the surface of the molten welding wire, achieving rapid cooling of the welding wire solution. This reduces the high temperature of the welding wire solution integrated into the gap after the two exhaust pipes are welded, which would otherwise require a long cooling time and result in slow welding speed of the exhaust pipes. This improves the welding efficiency of the exhaust pipes.

[0008] Preferably, a handle is fixedly connected to one side of the positioning rod, and the inner side of the handle is provided with multiple anti-slip protrusions.

[0009] The effect achieved by the above components is that by setting a handle, the handle can provide a point of leverage for personnel, allowing personnel to easily move the positioning rod by manually moving the handle.

[0010] Preferably, a spring is fitted onto the surface of the positioning rod, one end of the spring is fixedly connected to the support frame, and the other end of the spring is fixedly connected to the handle.

[0011] The effect achieved by the above components is that, by setting a spring, the spring can drive the handle and the positioning rod to always move towards the support frame under the extension and contraction force of the spring, reducing the possibility of the positioning rod sliding out of the circular hole during use.

[0012] Preferably, a limiting plate is fixedly connected to one side of the air duct, and the surface of the limiting plate is rectangular.

[0013] The effect achieved by the above components is as follows: by setting a limiting plate, the air duct can be intercepted when it is inserted into the support frame, which improves the ease of overlap between the inner walls of the circular hole and the through hole, and improves the assembly efficiency of the air duct and the support frame.

[0014] Preferably, a reinforcing block is fixedly connected to one side of the support frame, and the reinforcing block is fixedly connected to the machine body.

[0015] The effect achieved by the above components is that by setting up reinforcing blocks, the connection between the support frame and the machine body can be strengthened, reducing the possibility of the support frame separating from the machine body during use.

[0016] Preferably, the support device includes a screw, which is fixedly connected to the machine body, and a threaded cylinder is threadedly connected to the surface of the screw, with a base plate fixedly connected to one side of the threaded cylinder.

[0017] The effect achieved by the above components is as follows: by setting up a support device, the threaded cylinder is first manually rotated, causing the threaded cylinder to move up and down along the screw surface, which in turn causes the threaded cylinder to move up and down with the base plate, thereby adjusting the length of the screw and the threaded cylinder. When the base plate is moved to the appropriate position, the machine body is placed on the ground through the screw, the threaded cylinder and the base plate, thus completing the adjustment of the machine body's placement height. This reduces the situation where the machine body is placed on uneven ground and the height on both sides is different, which causes the machine body to shake during use, and improves the placement stability of the machine body.

[0018] Preferably, an anti-slip pad is fixedly connected to one side of the base plate, and the surface of the anti-slip pad is provided with multiple protrusions.

[0019] The effect achieved by the above components is that by setting up anti-slip pads, the anti-slip pads can increase the friction between the base plate and the ground, reducing the possibility of the base plate sliding when supporting the machine body.

[0020] Preferably, the surface of the threaded cylinder is fixedly connected with a plurality of protrusions, and the plurality of protrusions are arranged at equal intervals.

[0021] The effect achieved by the above-mentioned components is that by setting up protrusions, the protrusions can intercept the personnel's hands, reducing the possibility of the hands slipping when the personnel manually rotate the threaded cylinder.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] In this invention, a cooling device is provided to assist in cooling the welding wire solution, thereby accelerating the cooling and forming speed of the exhaust pipe welding position. This reduces the situation where the temperature of the welding wire solution in the gap between the two exhaust pipes is high after welding, which leads to a long cooling time for the welding wire solution and a slow welding forming speed of the exhaust pipe. This improves the welding forming efficiency of the exhaust pipe. Attached Figure Description

Detailed Implementation

[0029] Reference Figure 1-4As shown, this embodiment discloses a welding device for processing automotive exhaust pipes, including a body 1, a welding torch 2 disposed on one side of the body 1, a transmission rail 3 disposed on one side of the body 1, a motor 4 disposed on one side of the transmission rail 3, a clamp 5 disposed at the output end of the motor 4, a cooling device 6 disposed on one side of the body 1, and a support device 7 disposed at the bottom of the body 1. The cooling device 6 includes a support frame 61, which is fixedly connected to the body 1. A circular hole 62 is opened on one side of the support frame 61, and a positioning rod 63 is slidably connected to the inner wall of the circular hole 62. A fan is slidably connected to the inner wall of the support frame 61. A duct 67 has multiple nozzles 610 fixedly connected to its inner side, and a fan 69 fixedly connected to one side. The output end of the fan 69 is connected to the inner wall of the duct 67. A through hole 68 is provided on one side of the duct 67. The size and shape of the positioning rod 63 are adapted to the size and shape of the inner wall of the through hole 68. By setting a cooling device 6, the duct 67 is first manually moved, causing the fan 69 to move. When the duct 67 moves to the position inside the insertion support frame 61, the inner wall of the through hole 68 coincides with the inner wall of the circular hole 62. At this time, the positioning rod 63 is manually moved. 3. When the positioning rod 63 moves to the position where it is fully inserted into the circular hole 62 and the through hole 68, the positioning rod 63 is positioned inside the circular hole 62 and the through hole 68 to fix the position of the air duct 67, achieving rapid assembly of the air duct 67 and the support frame 61. At this time, the two exhaust pipes are fixed by the clamps 5 on both sides of the body 1. Then, the transmission rail 3 drives the two clamps 5 and the exhaust pipes to move in opposite directions. When the two exhaust pipes move to the position where they are in contact with each other, the contact point of the two exhaust pipes is located inside the air duct 67. At this time, the motors 4 on both sides simultaneously drive the two clamps 5 and the two exhaust pipes to move in opposite directions. The exhaust pipe rotates, and then the welding torch 2 is used to heat-melt the welding wire and integrate it into the gap between the two exhaust pipes, thus achieving the welding process of the two exhaust pipes. At this time, the fan 69 is started, which delivers airflow into the air duct 67, and the airflow is discharged through multiple air nozzles 610 and blown onto the surface of the molten welding wire, thereby achieving rapid cooling of the welding wire solution. This reduces the situation where the temperature of the welding wire solution integrated into the gap after the two exhaust pipes are welded is high, resulting in a long cooling time for the welding wire solution and a slow welding forming speed of the exhaust pipes, thus improving the welding forming efficiency of the exhaust pipes.

[0030] Reference Figure 2 and Figure 3As shown, this embodiment discloses a handle 64 fixedly connected to one side of the positioning rod 63. The inner side of the handle 64 is provided with multiple anti-slip protrusions. By setting the handle 64, the handle 64 can provide a point of leverage for the personnel, allowing the personnel to move the positioning rod 63 conveniently by manually moving the handle 64. A spring 65 is sleeved on the surface of the positioning rod 63. One end of the spring 65 is fixedly connected to the support frame 61, and the other end of the spring 65 is fixedly connected to the handle 64. By setting the spring 65, under the extension and contraction force of the spring 65, the spring 65 can drive the handle 64 and the positioning rod 63 to always move towards the support frame 61, reducing the possibility of the positioning rod 63 sliding out of the circular hole 62 during use.

[0031] Reference Figure 2 and Figure 3 As shown, this embodiment discloses a limiting plate 611 fixedly connected to one side of the air duct 67. The surface of the limiting plate 611 is rectangular. By setting the limiting plate 611, the air duct 67 can be intercepted by the limiting plate 611 when it is inserted into the support frame 61, which improves the convenience of aligning the inner walls of the circular hole 62 and the through hole 68, and improves the assembly efficiency of the air duct 67 and the support frame 61. A reinforcing block 66 is fixedly connected to one side of the support frame 61. The reinforcing block 66 is fixedly connected to the body 1. By setting the reinforcing block 66, the reinforcing block 66 can strengthen the connection between the support frame 61 and the body 1, reducing the possibility of the support frame 61 separating from the body 1 during use.

[0032] Reference Figure 4 As shown, this embodiment discloses a support device 7 including a screw 71, which is fixedly connected to the machine body 1. A threaded cylinder 72 is threadedly connected to the surface of the screw 71, and a base plate 73 is fixedly connected to one side of the threaded cylinder 72. By setting the support device 7, the threaded cylinder 72 is first manually rotated, causing the threaded cylinder 72 to move up and down along the surface of the screw 71, which in turn causes the threaded cylinder 72 to drive the base plate 73 to move up and down, thereby adjusting the length of the screw 71 and the threaded cylinder 72. When the base plate 73 moves to the appropriate position, the machine body 1 is placed on the ground through the screw 71, the threaded cylinder 72, and the base plate 73, thus adjusting the placement height of the machine body 1. This reduces the situation where the machine body 1 is placed on uneven ground, resulting in uneven heights on both sides and causing the machine body 1 to shake during use, thereby improving the placement stability of the machine body 1.

[0033] Reference Figure 4As shown in the figure, this embodiment discloses that an anti-slip pad 74 is fixedly connected to one side of the base plate 73. The surface of the anti-slip pad 74 is provided with multiple protrusions. By setting the anti-slip pad 74, the anti-slip pad 74 can increase the friction between the base plate 73 and the ground, and reduce the slippage of the base plate 73 when supporting the machine body 1. The surface of the threaded cylinder 72 is fixedly connected with multiple protrusions 75. The multiple protrusions 75 are arranged at equal distances. By setting the protrusions 75, the protrusions 75 can intercept the personnel's hands, and reduce the slippage of the hands when the personnel manually rotate the threaded cylinder 72.

[0034] Working principle: First, manually move the air duct 67, causing it to move the fan 69. When the air duct 67 moves to the position inside the support frame 61, the inner wall of the through hole 68 coincides with the inner wall of the circular hole 62. At this time, manually move the positioning rod 63. When the positioning rod 63 moves to the position where it is fully inserted into the circular hole 62 and the through hole 68, the positioning rod 63 is positioned inside the circular hole 62 and the through hole 68, fixing the air duct 67 in place, achieving rapid assembly of the air duct 67 and the support frame 61. Then, fix the two exhaust pipes respectively using the clamps 5 on both sides of the body 1. The transmission rail 3 drives the two clamps 5 and the exhaust pipe to move in opposite directions. When the two exhaust pipes move to the position where they are in contact with each other, the contact point of the two exhaust pipes is located inside the air duct 67. At this time, the motors 4 on both sides drive the two clamps 5 and the two exhaust pipes to rotate simultaneously. Then, the welding gun 2 is used to heat melt the welding wire and integrate it into the gap between the contact points of the two exhaust pipes, thus achieving the welding process of the two exhaust pipes. At this time, the fan 69 is started, so that the fan 69 delivers airflow into the air duct 67, and the airflow is discharged through multiple air nozzles 610 and blown onto the surface of the hot-melted welding wire, thereby achieving rapid cooling of the welding wire solution.

[0035] First, manually rotate the threaded cylinder 72 so that it moves up and down along the surface of the screw 71, causing the threaded cylinder 72 to move the base plate 73 up and down, thereby adjusting the length of the screw 71 and the threaded cylinder 72. When the base plate 73 is moved to the appropriate position, place the machine body 1 on the ground through the screw 71, the threaded cylinder 72 and the base plate 73 to complete the adjustment of the placement height of the machine body 1.
