[0002] Automobile exhaust is the waste gas generated when motor vehicles are running, including carbon monoxide (CO), nitrogen oxides (NOX), hydrocarbons (HC) and solid suspended particulate matter (PM). It is one of the culprits of air pollution. Reducing pollution and emissions through the use of catalytic purification technology is one of the key technologies for engine exhaust after-treatment. Existing catalysts mostly use DOC+DPF+mixer+SCR to remove harmful substances in automobile exhaust. The main function of the mixer is to crush urea, so that the exhaust gas and urea are fully mixed, ensuring the uniformity of the airflow at the SCR intake end and improving the SCR conversion efficiency.

[0003] During the preparation of the mixer, multiple brackets need to be welded on the side wall of the mixing tube. Since one end of the mixing tube is in a bent state, the mixing tube is easy to rotate downward under the influence of gravity, and the surface of the mixing tube is smooth. When the brackets are welded on the surface of the mixing tube, the brackets are easy to slide on the side wall of the mixing tube, resulting in deviation of the welding position and reducing the qualified rate of the finished product.

[0004] Therefore, it is necessary to provide a new automobile mixer elbow bracket welding forming clamping device to solve the above problems. Utility Model Content

[0014] The utility model provides a welding and forming clamping device for a bent pipe bracket for an automobile mixer. Before welding the bent pipe, the bent pipe is placed on the surface of the support mechanism. The straight end of the bent pipe is fixed by the first fixing mechanism, and the bent end of the bent pipe is fixed by the second fixing mechanism, thereby fixing the bent pipe on the surface of the support mechanism and preventing the bent pipe from shifting during the welding process.

[0026] One end of the base 1 is installed with a first fixing mechanism 4 for fixing the straight pipe end of the mixing bend 3, and the first fixing mechanism 4 includes a first mounting plate 41.

One end of the first cylinder 42 is connected to a fixing plate 43, and one end of the fixing plate 43 is annular and engages with the straight pipe end of the mixing bend 3. When the first cylinder 42 is opened, the operation of the first cylinder 42 pushes the fixing plate 43 to move into the interior of the straight pipe end of the mixing bend 3, thereby fixing the straight pipe end of the mixing bend 3.

[0027] The other end of the base 1 is installed with a second fixing mechanism 5 for fixing the bent end of the mixing elbow 3, and the second fixing mechanism 5 includes a guide rail 51 and a slide 52. The guide rail 51 is symmetrically installed on the surface of the base 1, and the surface of the guide rail 51 is slidably connected to the slide 52; the surface of the base 1 is installed with a second cylinder 53 that drives the slide 52 to move along the guide rail 51, and the surface of the slide 52 is fixedly connected to the positioning block 55; a flange 31 is provided at one end of the bent mixing elbow 3, and the flange 31 engages with the side wall of the positioning block 55, and the second cylinder 53 is opened. The second cylinder 53 pushes the slide 52 to move along the guide rail 51, and the slide 52 is moved close to the flange 31 while the positioning block 55 is fixed, so that one end of the positioning block 55 enters the interior of the flange 31 to preliminarily fix the flange 31.

[0028] The second fixing mechanism 5 also includes a third cylinder 54, the side wall of the slide 52 is installed with the third cylinder 54, one end of the third cylinder 54 is installed with a connecting plate 56, the surface of the connecting plate 56 is rotatably connected to a plurality of clamping plates 57, and the clamping plates 57 clamp the side wall of the flange 31; the surface of the clamping plate 57 is provided with a "V"-shaped sliding groove 58, and the side wall of the positioning block 55 is installed with a plurality of clamping plates 59, which are slidably connected and clamp the inside of the sliding groove 58; when the third cylinder 54 is opened, the third cylinder 54 drives the connecting plate 56 to move in the direction of the third cylinder 54, and the connecting plate 56 drives the clamping plate 59 and the sliding groove 58 to move, and the clamping plate 59 moves in the "V"-shaped sliding groove 58, and the clamping plate 59 pushes the clamping plate 59 to rotate, so that one end of the clamping plate 59 rotates to press against the side wall of the flange 31, thereby fixing the flange 31.

The interior of the magnetic fixing block 72, the positioning rod 75 limits the bracket 6, so that the bracket 6 is accurately installed inside the magnetic fixing block 72. At this time, the bracket 6 is aligned with the installation position on the surface of the mixing elbow 3, and the fourth cylinder 73 is opened. The fourth cylinder 73 drives the slide 71 and the block 76 to move downward along the side wall of the second mounting plate 74, so that the bracket 6 accurately contacts the installation position on the surface of the mixing elbow 3, and with the operation of the fourth cylinder 73, the magnetic fixing block 72 squeezes the bracket 6, so that the bracket 6 squeezes the surface of the mixing elbow 3, ensuring that the position of the bracket 3 does not shift during the later welding process, thereby improving the qualified rate of finished products.

[0030] The working principle of the elbow support welding and forming clamping device for automobile mixers provided by the utility model is as follows: the mixing elbow 3 is placed on the surfaces of the support plate 22 and the second clamping plate 24, and the mixing elbow 3 is aligned with the fixing plate 43 and the positioning block 55 respectively. The cylinder is connected to the air pump, and the first cylinder 42 is turned on. The operation of the first cylinder 42 pushes the fixing plate 43 to move into the interior of the straight pipe end of the mixing elbow 3, thereby fixing the straight pipe end of the mixing elbow 3. The second cylinder 53 is turned on. The second cylinder 53 pushes the slide 52 to move along the guide rail 51. The slide 52 is waiting for the positioning block 55 to move close to the flange 31, so that one end of the positioning block 55 enters the interior of the flange 31. The third cylinder 54 is turned on. The third cylinder 54 drives the connecting plate 56 to move in the direction of the third cylinder 54. The connecting plate 56 drives the clamping plate 59 and the sliding groove 58 to move. The clamping plate 59 moves in the sliding groove 58 in a "V" shape. The clamping plate 59 pushes the clamping plate 59 to rotate, so that one end of the clamping plate 59 rotates to press against the side wall of the flange 31, thereby fixing the flange 31 and preventing the mixing elbow 3 from shifting in position during welding. The bracket 6 is placed into the interior of the magnetic fixing block 72, and the positioning rod 75 limits the bracket 6 so that the bracket 6 is accurately installed in the interior of the magnetic fixing block 72. At this time, the bracket 6 is aligned with the installation position on the surface of the mixing elbow 3, and the fourth cylinder 73 is opened. The fourth cylinder 73 drives the slide 71 and the clamping block 76 to move downward along the side wall of the second mounting plate 74, so that the bracket 6 accurately contacts the installation position on the surface of the mixing elbow 3. As the fourth cylinder 73 operates, the magnetic fixing block 72 squeezes the bracket 6, so that the bracket 6 squeezes the surface of the mixing elbow 3, and the connection between the bracket 6 and the mixing elbow 3 is welded. During the welding process, the bracket 3 is squeezed and fixed by the magnetic fixing block 72, and the position of the bracket 6 does not shift during the welding process, thereby improving the qualified rate of finished products.
