[0005] In view of the deficiencies in the prior art, the present invention provides a processing and welding device for muffler production, which achieves the purpose of solving the above-mentioned problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A processing welding device for muffler production, including a welding table, a fixed shaft is fixedly connected to the top of the welding table, a lift is slidably connected to the outer wall of the fixed shaft, a fixed bar is fixedly connected to the top of the welding table, a sliding plate is slidably connected to the top of the fixed bar, a connecting piece is fixedly connected to the bottom of the lifter, a welding head is fixedly connected to the bottom end of the connecting piece, and a constant temperature mechanism is arranged on the top of the sliding plate;

[0007] The constant temperature mechanism includes:

[0008] The pad is a circular disc-shaped structure. A motor is fixedly connected to the bottom of the welding head. A rotating shaft is fixedly connected to the output end of the motor. One end of the rotating shaft passes through the pad and is fixedly connected to a turntable. The top of the pad is rotatably connected to the bottom of the turntable. The pad is used to support the turntable.

[0009] The heater has a bottom that is fixedly connected to the top of the turntable, a heat conducting plate that is fixedly connected to the top of the heater, a muffler that contacts one side of the heat conducting plate, a connecting pipe that is plugged into the top of the muffler, and the heater is used to heat the heat conducting plate.

[0010] Preferably, the top of the pad is rotatably connected to a rotating rod via a bearing, and the outer wall of the rotating rod is fixedly connected to a rotating wheel.

[0011] Preferably, a tooth block is fixedly connected to the outer wall of the rotating wheel, and a gear is fixedly connected to the outer wall of the heater, and the gear is meshed with the rotating wheel through the tooth block.

[0012] Preferably, a circular sleeve is fixedly connected to the top of the rotating wheel, and bristles are fixedly connected to the outer wall of the circular sleeve, and the bristles are elastic.

[0013] Preferably, the inner wall of the circular sleeve is provided with a flow guiding mechanism, and the flow guiding mechanism comprises a square groove, and the square groove is opened in the inner wall of the circular sleeve.

[0014] Preferably, blades are fixedly connected to the inner wall of the circular sleeve, a connecting shaft is fixedly connected to one side of the blade, and the blades are arranged at an angle.

[0015] Preferably, a semicircular air groove is formed on the outer wall of the circular sleeve, and a flow guide cover is fixedly connected to the outer wall of the circular sleeve.

[0016] Preferably, an inclined air groove is provided on the inner wall of the air deflector, the inclined air groove is connected to the semicircular air groove through the air deflector, the interior of the semicircular air groove is connected to the interior of the circular sleeve, and the interior of the circular sleeve is connected to the exterior of the circular sleeve through the square groove.

[0017] The present invention provides a processing and welding device for muffler production, which has the following beneficial effects:

[0018] 1. The present invention sets a constant temperature mechanism. When the muffler is inserted between the heat conducting plate and the heater, the heat of the heat conducting plate is heated by starting the heater in advance and transferred to the muffler in real time. The muffler is firmly clamped for circumferential welding and is automatically preheated, thereby increasing the temperature of the welding area and the surrounding parent material, reducing the stress and deformation problems caused by temperature differences during welding, and realizing automatic welding integration.

[0019] 2. The present invention sets a constant temperature mechanism. Since the number of gear teeth is much larger than that of the gear block, the rotation speed of the rotating wheel and the circular sleeve is much faster than that of the gear and the muffler. Therefore, the bristles can quickly wipe the welded and unwelded positions of the muffler and the connecting pipe at a faster rotation speed, and remove the oil, rust, dust or other impurities in the welding area, so as to avoid the welding problems such as bubbles, slag inclusions, incomplete fusion, incomplete penetration, etc. that may be generated by these pollutants during the welding process.

[0020] 3. The present invention provides a guide mechanism to spray outward through the inclined air slot to clean the welding area, and at the same time, uses the airflow to blow off the welding slag and particles before welding in real time, and at the same time uses the inclined shape of the guide cover and the inclined air slot to guide the air, so that the air is blown to the muffler and the connecting pipe welding area in an inclined upward direction. While completing the cleaning of the welding area, the blowing of the airflow is also used to fully dry the moisture and water that may exist in the welding area under the high evaporation effect of the heated muffler, so as to avoid the existence of moisture and cause the generation of unfusion and bubbles in welding;

[0021] 4. The present invention sets a flow guide mechanism. When the airflow is blown out through the inclined air groove, the inclined bristles will conduct subsequent flow guidance. The inclined air groove with a small opening is used to quickly and forcefully blow away the residual moisture and stains in the welding area between the muffler and the connecting pipe in a high-pressure and strong manner and under the effect of flow guidance. The air blowing method guided along the direction of the bristles is used to realize the use of the bristles to peel off the stain particles and then blow them away. There will be no problem that the particle residue falls into each bristle and is mixed, and the problem of getting dirty with use and needing to be cleaned repeatedly will occur;

[0022] 5. The present invention sets a flow guide mechanism so that the air drawn in through the square groove is close to the heat conduction plate, and the air temperature is relatively high, so that the air at the position with higher temperature can be drawn in and ejected, thereby reducing the problem of temperature drop in the welding area between the muffler and the connecting pipe due to evaporation of water by blowing.

DETAILED DESCRIPTION

[0039] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a processing welding device for muffler production, comprising a welding table 2, a fixed shaft 1 is fixedly connected to the top of the welding table 2, a lifter 5 is slidably connected to the outer wall of the fixed shaft 1, a fixed bar 8 is fixedly connected to the top of the welding table 2, a sliding plate 9 is slidably connected to the top of the fixed bar 8, a connecting piece 6 is fixedly connected to the bottom of the lifter 5, a welding head 7 is fixedly connected to the bottom end of the connecting piece 6, and a constant temperature mechanism 3 is arranged on the top of the sliding plate 9;

[0040] The constant temperature mechanism 3 comprises:

[0041] The pad 301 is a circular disc-shaped structure. The bottom of the welding head 7 is fixedly connected to the motor 12. The output end of the motor 12 is fixedly connected to the shaft 13. One end of the shaft 13 passes through the pad 301 and is fixedly connected to the turntable 302. The top of the pad 301 is rotatably connected to the bottom of the turntable 302. The pad 301 is used to support the turntable 302.

[0042] The heater 303 has its bottom fixedly connected to the top of the turntable 302, a heat conducting plate 304 fixedly connected to the top of the heater 303, one side of the heat conducting plate 304 contacts a muffler 10, a connecting pipe 11 is plugged into the top of the muffler 10, and the heater 303 is used to heat the heat conducting plate 304.

[0043] When in use, the muffler 10 and the connecting pipe 11 to be welded are placed on the turntable 302, and then the lifter 5 is started to control the connecting piece 6 and the welding head 7 to descend to the welding position of the muffler 10 and the connecting pipe 11, and then the motor 12 is started to control the rotation of the turntable 302 through the rotating shaft 13. When the turntable 302 rotates, the muffler 10 and the connecting pipe 11 on the top are driven to rotate, so that the automatic circumferential welding of the muffler 10 and the connecting pipe 11 is completed through the continuous electric welding of the welding head 7;

[0044] Example 2: Please refer to Figure 1-10 On the basis of the first embodiment, the present invention provides a technical solution: the top of the pad 301 is rotatably connected to a rotating rod 311 through a bearing 306 , and the outer wall of the rotating rod 311 is fixedly connected to a rotating wheel 307 .

[0045] A tooth block 308 is fixedly connected to the outer wall of the rotating wheel 307 , and a gear 305 is fixedly connected to the outer wall of the heater 303 . The gear 305 is meshed with the rotating wheel 307 through the tooth block 308 .

[0046] A circular sleeve 309 is fixedly connected to the top of the rotating wheel 307 , and bristles 310 are fixedly connected to the outer wall of the circular sleeve 309 . The bristles 310 are elastic.

[0047] When the muffler 10 is placed on the turntable 302, it is first inserted between the four heat conducting plates 304 and then pushed down to the bottom turntable 302. Therefore, the four heat conducting plates 304 support the muffler 10 and the muffler 10 is supported by friction. When the turntable 302 rotates, the muffler 10 can be firmly grasped by the top heater 303 and the heat conducting plates 304 for rotation welding, thereby preventing looseness during welding.

[0048] When the muffler 10 is inserted between the heat conducting plate 304 and the heater 303, the heat of the heat conducting plate 304 is heated by starting the heater 303 in advance and is transferred to the muffler 10 in real time, so that the muffler 10 is firmly clamped for circumferential welding and is automatically preheated, thereby preheating the welding area and the surrounding parent material to increase the temperature, reduce the stress and deformation problems caused by temperature differences during welding, and realize automatic welding integration.

[0049] As the muffler 10 is rotated by the turntable 302 and the welding head 7 is used to weld the welding area of ​​the muffler 10 and the connecting pipe 11, the muffler 10 is constantly in contact with the bristles 310 and is cleaned by the bristles 310 when it is rotated. Therefore, after the muffler 10 and the connecting pipe 11 are slowly rotated and welded for one circle, the welded position is also in contact with the bristles 310 and is cleaned by the bristles 310 as it rotates for one circle, completing the cleaning of the welding slag in the welding area after automatic welding.

[0050] The turntable 302 drives the gear 305 on the outer wall to rotate through the heater 303, and the gear 305 meshes with the tooth block 308 to drive the rotating wheel 307 to rotate. The rotation of the rotating wheel 307 drives the circular sleeve 309 on the top and the bristles 310 on the outer wall to rotate synchronously. Since the bearing 306 makes the rotating rod 311 and the rotating wheel 307 rotate in a fixed position, the center of the rotation of the circular sleeve 309 and the bristles 310 remains unchanged, and the circular sleeve 309 and the bristles 310 continue to rotate, and the muffler 10 that is rotating at this time is further The rotating sweeping work of the step, since the number of teeth of the gear 305 is much greater than that of the gear block 308, the rotating speed of the wheel 307 and the circular sleeve 309 is much faster than that of the gear 305 and the muffler 10, so that the bristles 310 continuously wipe the welded and unwelded positions of the muffler 10 and the connecting pipe 11 at a faster rotating speed, and remove the oil, rust, dust or other impurities in the welding area, so as to avoid the welding problems such as bubbles, slag inclusions, incomplete fusion, incomplete penetration, etc. that may be generated by these pollutants during the welding process;

[0051] Example 3: Please refer to Figure 1-15 On the basis of the first and second embodiments, the present invention provides a technical solution: a flow guide mechanism 4 is provided on the inner wall of the circular sleeve 309 , and the flow guide mechanism 4 includes a square groove 401 , and the square groove 401 is opened in the inner wall of the circular sleeve 309 .

[0052] The inner wall of the circular sleeve 309 is fixedly connected with a blade 403 , one side of the blade 403 is fixedly connected with a connecting shaft 404 , and the blade 403 is arranged to be inclined.

[0053] A semicircular air groove 405 is formed on the outer wall of the circular sleeve 309 , and a flow guide cover 407 is fixedly connected to the outer wall of the circular sleeve 309 .

[0054] The inner wall of the air deflector 407 is provided with an inclined air groove 408 , which is connected to the semicircular air groove 405 through the air deflector 407 . The interior of the semicircular air groove 405 is connected to the interior of the circular sleeve 309 , and the interior of the circular sleeve 309 is connected to the exterior of the circular sleeve 309 through the square groove 401 .

[0055] As the circular sleeve 309 rotates, the blades 403 and the connecting shaft 404 on the inner wall of the circular sleeve 309 are driven to rotate. The rotation of the blades 403 realizes that the air below is drawn into the upper part of the blades 403, so that the air enters the circular sleeve 309 through the square grooves 401 opened outside the circular sleeve 309, and then enters each semicircular air groove 405 through the rising air. Since the top of the circular sleeve 309 is closed, the upward air enters the inclined air groove 408 in the guide cover 407 through the semicircular air groove 405, and finally sprays outward through the inclined air groove 408. The welding area is cleaned and swept, and the welding slag and particles before welding are blown off by airflow in real time. At the same time, the inclined shape of the air guide cover 407 and the inclined air groove 408 is used to guide the air, so that the air is blown to the welding area of ​​the muffler 10 and the connecting pipe 11 in an inclined upward direction. While the welding area is cleaned, the airflow is used to blow the moisture and water that may exist in the welding area under the high evaporation effect of the heated muffler 10, so as to avoid the existence of moisture and cause the generation of unfusion and bubbles in welding;

[0056] At the same time, when the airflow is blown out through the inclined air groove 408, the inclined bristles 310 will be used to guide the airflow. The inclined air groove 408 with a smaller opening can quickly and forcefully blow away the residual moisture and stains in the welding area of ​​the muffler 10 and the connecting pipe 11 in a high pressure and strong manner and under the effect of the guide. The air blowing method guided in the direction of the bristles 310 can be used to realize the use of the bristles 310 to peel off the stain particles and then blow them away, so that the particle residue will not fall into each bristle 310 and be mixed, and the problem of getting dirty with use and needing to be cleaned repeatedly will not occur.

[0057] The air drawn in through the square groove 401 is close to the heat conducting plate 304, and the air temperature is relatively high, so that the air at the position with relatively high temperature can be drawn in and ejected, thereby reducing the problem of temperature drop in the welding area of ​​the muffler 10 and the connecting pipe 11 due to water evaporation caused by blowing air;

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
