Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a welding assembly device for automotive intercooler pipes. Background Technology

[0002] The intercooler is a heat exchanger specific to turbocharged and supercharged vehicles, installed between the turbocharger and the intake manifold. During the production process, a welding assembly device is used to weld the intercooler fins to the upper and lower water pipes. This welding assembly welds the intercooler pipes, and to ensure uniform weld width after welding, spot welding is performed on the pipe seams beforehand. However, due to localized heating, some pipe sections may tilt upwards after spot welding, increasing the weld width at that point. If this problem is not detected in time, the welded pipes may have a certain degree of tilt, affecting the tightness of the subsequent intercooler assembly. Summary of the Invention

[0005] Furthermore, the welding operating table has a rectangular structure, and a support bracket is installed at the bottom edge of the welding operating table; guide cylinders are installed on both the front and rear sides of the welding operating table.

[0006] Furthermore, the output end of the guide cylinder is equipped with a clamping plate, wherein the inner side of the clamping plate is provided with an anti-slip pad; the two clamping plates are slidably installed on the inner side of the welding operation table.

[0007] Furthermore, a bearing housing is installed on the front side of the positioning ring; a rotating threaded rod is rotatably installed inside the bearing housing.

[0008] Furthermore, the outer sides of both ends of the rotating threaded rod are provided with threads in opposite directions, and movable plates are installed on the outer sides of both ends of the rotating threaded rod.

[0009] Furthermore, a traction plate is installed on the side end of each of the two movable plates; the inner end of the traction plate is an inclined structure, and a positioning plate is installed on the inner side of the traction plate through the positioning ring.

[0010] Furthermore, a support plate is installed on the top of the guide bracket; a positioning rod is installed at the middle position of the top of the support plate.

[0011] Furthermore, the positioning rod has a cylindrical structure, and a rotating block is rotatably mounted on the top of the positioning rod; four evenly distributed support rods are mounted on the outer side of the rotating block.

Then, the rotating block makes the shielding cover lower and placed inside the pipeline. During the welding operation, it can prevent welding slag from entering the inside of the pipeline. The conical structure at the top of the shielding cover can guide the welding slag to the annular groove for collection, effectively avoiding welding slag residue in the pipeline and the intercooler, ensuring the cleanliness of the intercooler cavity, and reducing problems such as pipeline blockage and poor heat exchange inside the intercooler.

[0020] Please refer to Figures 1 to 9 : Example 1: This invention proposes a welding assembly device for automotive intercooler pipes, comprising: a welding operating table 1, which is rectangular in structure, and a support bracket 101 is installed at the bottom edge of the welding operating table 1; guide cylinders 102 are installed on both the front and rear sides of the welding operating table 1; a clamping plate 103 is installed at the output end of the guide cylinder 102, wherein the inner side of the clamping plate 103 is provided with an anti-slip pad; the two clamping plates 103 are slidably installed on the inner side of the welding operating table 1.

[0021] In this embodiment of the invention, the position of the intercooler inside the welding workbench 1 is adjusted according to the welding position of the intercooler pipe, so that the intercooler is in the area between the two clamping plates 103 and moves left and right. The guide cylinders 102 at the front and rear of the welding workbench 1 drive the clamping plates 103 to move respectively. After the two clamping plates 103 are adjusted to different positions, the intercooler is fixed to ensure the stability of the welding process.

[0022] In Example 2, based on Example 1, two guide rods 2 are installed on the rear top of the welding workbench 1. The guide rods 2 are cylindrical, and guide brackets 201 are slidably installed on the outer side of the guide rods 2. A drive pump is installed in the middle of the rear side of the welding workbench 1 and the support bracket 101, and the output end of the top of the drive pump is connected to the rear bottom of the guide bracket 201. A positioning ring 202 is installed at the front end of the guide bracket 201. A bearing seat 203 is installed on the front side of the positioning ring 202. A rotating threaded rod 204 is rotatably installed inside the bearing seat 203. The outer sides of both ends of the rotating threaded rod 204 are provided with threads in opposite directions, and movable plates 2 are installed on the outer sides of both ends of the rotating threaded rod 204. 05; A traction plate 206 is installed on the side end of both movable plates 205; The inner end of the traction plate 206 is inclined, and a positioning plate 207 is installed on the inner side of the positioning ring 202 through the traction plate 206; A support plate 208 is installed on the top of the guide bracket 201; A positioning rod 209 is installed in the middle of the top of the support plate 208; The positioning rod 209 is cylindrical, and a rotating block 2010 is rotatably installed on the top of the positioning rod 209; Four evenly distributed support rods 2011 are installed on the outer side of the rotating block 2010; A guide slide rod 2012 is slidably installed through the outer end of the support rod 2011, wherein a damping pad is provided at the part where the outer side of the guide slide rod 2012 contacts the outer end of the support rod 2011;The guide slide rod 2012 has a limiting protrusion at its top and a shield 2013 installed at its bottom. The shield 2013 has a conical structure in the middle. The four shields 2013 have different specifications, and the edge of the top of the shield 2013 has an annular groove. The distance between the two positioning plates 207 is adjusted according to the diameter of the intercooler pipe. The rotating threaded rod 204 rotates inside the bearing seat 203 on the outer side of the positioning ring 202, which drives the two movable plates 205 to move synchronously. The side ends of the two movable plates 205 drive the traction plate 206 to move, so that the inner end of the traction plate 206 drives the positioning plate 207 to clamp the outside of the pipe, positioning the pipe. At the same time, the pipe is in the middle position between the positioning ring 202 and the rotating ring 3. The rotating block 2010 rotates on the top of the positioning rod 209 on the top of the support plate 208, so that the outer side of the rotating block 2010 is driven by the support rod 2011. The shield 2013 at the bottom of the guide slide rod 2012 rotates, positioning the appropriately sized shield 2013 above the pipeline. The guide slide rod 2012 is pushed downwards from the outer end of the support rod 2011, causing the shield 2013 to be inserted into the inside of the pipeline, sealing the inside and blocking weld slag generated during welding. The conical structure at the top of the shield 2013 guides the weld slag to the annular groove at the top edge of the shield 2013, preventing weld slag from entering the pipeline and the intercooler, ensuring the cleanliness of the automotive intercooler. The drive pump at the rear of the welding operating table 1 and the support bracket 101 moves the rear end of the guide bracket 201 downwards along the guide vertical rod 2, causing the front end of the guide bracket 201 to move the positioning ring 202 downwards. This moves the pipeline fixed by the positioning plate 207 downwards to the welding location of the intercooler, fixing the intercooler and pipeline in a fixed position to prevent movement during welding.

[0023] In Example 3, based on Example 1, a guide slider 301 is provided at the bottom of the positioning ring 202, and a rotating ring 3 is rotatably mounted at the bottom of the positioning ring 202. The top of the rotating ring 3 has a groove, and the guide slider 301 is rotatably mounted in the groove at the top of the rotating ring 3. A drive ring 302 is provided on the top outer side of the rotating ring 3. A servo motor is mounted on the outer side of the positioning ring 202, and a gear is mounted on the output end at the bottom of the servo motor. The side of the gear meshes with the outer side of the drive ring 302. A bearing seat 2 303 is mounted on the outer side of the rotating ring 3. A rotating threaded rod 2 304 is rotatably mounted inside the bearing seat 2 303. The outer sides of both ends of the rotating threaded rod 2 304 have threads in opposite directions, and movable plates 2 305 are rotatably mounted on the outer sides of both ends of the rotating threaded rod 2 304. Traction plates 2 306 are mounted on the side ends of both movable plates 2 305. Welding guns 307 are mounted through the inner side of both traction plates 2 306, and are adjusted according to the position of the weld seam on the pipeline. The position between the two welding torches 307 is adjusted so that the rotating threaded rod 304 rotates within the bearing seat 303 on the outer side of the rotating ring 3, driving the two movable plates 305 to move. The side ends of the two movable plates 305 drive the traction plate 306 to move through the side of the rotating ring 3, so that the inner end of the traction plate 306 drives the welding torch 307 to the pipe weld position. The gear at the output end of the servo motor on the outer side of the positioning ring 202 meshes and drives the drive ring 302 to rotate. The top of the rotating ring 3 rotates outside the guide slider 301. The rotating ring 3 drives the welding torch 307 to the outside of the pipe weld joint through the traction plate 306. Spot welding is performed at the relative position of the pipe weld joint. Spot welding is performed at the same time to prevent the relative position from lifting due to local overheating. Spot welding is performed at the relative position to ensure that the weld width is uniform. The welding torch 307 continues to rotate outside the pipe weld joint to perform welding operations, ensuring that the horizontality of the pipe is consistent after welding, and ensuring the stability and tightness of the subsequent assembly of the automotive intercooler.

[0024] The working principle of this embodiment is as follows: The intercooler is placed inside the welding operating table 1, in the area between two clamping plates 103. The guide cylinders 102 at the front and rear positions drive the clamping plates 103 to move respectively. The two clamping plates 103 move to different positions to fix the intercooler. The distance between the two positioning plates 207 is adjusted according to the diameter of the intercooler pipeline. Rotating the rotating threaded rod 204 drives the two movable plates 205 to move synchronously. The side ends of the two movable plates 205 drive the positioning plate 207 to position the pipeline through the traction plate 206, so that the welding position below the pipeline is level with the output end of the welding torch 307. The rotating block 2010 rotates on the top of the positioning rod 209, and through the support rod 2011, drives the shield 2013 at the bottom of the guide slide rod 2012 to be above the pipeline. Pushing the guide slide rod 2012 downward drives the shield 2013 to move downward. 3. Inserted inside the pipeline to block welding slag, the drive pump on the back of the welding operating table 1 and support bracket 101 drives the guide bracket 201 to move downward along the guide vertical rod 2. The front end of the guide bracket 201 drives the pipeline fixed inside the positioning ring 202 to move downward and place it on the intercooler. Then, according to the position of the weld seam on the pipeline, adjust the position between the two welding guns 307. Rotate the rotating threaded rod 304 to drive the two movable plates 305 to drive the welding gun 307 to the position of the pipeline weld seam through the traction plate 306. The servo motor on the outside of the positioning ring 202 engages to drive the drive ring 302 to rotate, so that the top of the rotating ring 3 rotates outside the guide slider 301. The rotating ring 3 drives the welding gun 307 to the outside of the pipeline weld joint through the traction plate 306. Spot welding is performed at the relative position of the pipeline weld joint to ensure that the horizontality of the pipeline is consistent after welding.
