[0002] A car is a power-driven vehicle with four or more wheels. It is not a track-borne vehicle. It is mainly used to carry people and goods. It can also tow vehicles carrying people and goods, or be used for special purposes. With the rapid development of the automobile industry, cars have become an important means of transportation in daily life. Automobile oil pipes are an important part of the power system. During processing, the oil pipes are connected by laser welding. When welding, the end ports of the pipes need to be spliced ​​together first and then welding work can be performed.

[0003] The existing technology mainly aligns and docks manually, and then uses equipment to perform automatic welding. However, when performing laser welding, in order to ensure the welding quality and strength, the gap between the pipe end faces cannot be completely close, and it is difficult to control the appropriate welding gap through manual alignment. Therefore, we propose a vehicle oil pipe welding device. Utility Model Content

After the oil pipes are pressed and locked by the upper guide wheel, the positioning plate is pulled out to carry out welding.

[0007] Optionally, an opening is provided on the surface of the upper plate directly above the laser welding gun, and the opening runs through both sides of the upper plate.

DETAILED DESCRIPTION

[0022] See also Figure 1-2 The utility model provides a technical solution: a vehicle oil pipe welding device, including a base 1 and an upper plate 2, the four corners of the bottom of the base 1 are supported by supporting legs 13, four supporting legs 13 are provided, the base 1 is stably supported by the four supporting legs 13, a plurality of lower guide wheels 11 are evenly installed at the front and rear ends of both sides of the surface of the base 1, and a total of eight lower guide wheels 11 are provided, and four mutually symmetrical lower guide wheels 11 are respectively installed on both sides of the middle position of the base 1, and two oil pipes to be welded together can be laterally supported above the lower guide wheel 11 on the left or right side.

[0023] A second electric push rod 4 is vertically installed below the middle position of the base 1 between the lower guide wheels 11. The top of the second electric push rod 4 passes through the top of the base 1 and is fixed with a lifting plate 41. A positioning plate 411 is longitudinally fixed on the surface of the lifting plate 41, which can be electrically lifted and lowered by the second electric push rod 4. When it is lifted and placed between the lower guide wheels 11, the oil pipe is supported on the lower guide wheels 11 and slides toward the positioning plate 411 and contacts the surface of the positioning plate 411, so it can be quickly aligned. The thickness of the positioning plate 411 is equal to the gap between the oil pipe welds, so the gap between the oil pipes can be quickly located.

[0024] The upper plate 2 is laterally supported by the support rods 12 at the four corners below it and is placed directly above the base 1. The four support rods 12 have the same length so that the upper plate 2 is parallel to the surface of the base 1. First electric push rods 22 are vertically installed on both sides of the surface of the upper plate 2. A pressure plate 3 is laterally fixed to the lower end of the first electric push rod 22. The pressure plate 3 can be driven to rise and fall by the first electric push rod 22. A plurality of upper guide wheels 31 are evenly installed at the front and rear ends on both sides below the pressure plate 3. There are also eight upper guide wheels 31, and four symmetrical upper guide wheels 31 are respectively installed on both sides of the middle position of the pressure plate 3. The size of the upper guide wheel 31 is the same as that of the lower guide wheel 11 and corresponds one to one. After the pressure plate 3 is driven to lower its height, the upper guide wheel 31 presses on the surface of the oil pipes on both sides, thereby locking the oil pipes on both sides that have been aligned.

[0025] A stepper motor 111 is installed on the side plate surface of the lower guide wheel 11 on the right side of the front end above the base 1. The stepper motor 111 is connected to the lower guide wheel 11 for transmission. The stepper motor 111 can drive the lower guide wheel 11 on the right side of the front end to rotate. A transmission rod 112 is connected horizontally between the lower guide wheels 11 at the front end above the base 1, which can make all the lower guide wheels 11 at the front end rotate synchronously, thereby driving the oil pipes on both sides to rotate synchronously.

[0026] A laser welding gun 32 is installed in the middle position of the pressure plate 3 between the upper guide wheels 31. An opening 21 is provided on the surface of the upper plate 2 directly above the laser welding gun 32. The opening 21 passes through both sides of the upper plate 2. The wire connected between the laser welding gun 32 and the laser welder passes through the opening 21. The welding head of the laser welding gun 32 is located below the pressure plate 3 and placed directly above the positioning plate 411. The welding head of the laser welding gun 32 will align with the welds where the pipes on both sides are aligned. The positioning plate 411 is first driven downward by the second electric push rod 4, and then when the pipe is driven to rotate, the pipe can be welded and fixed.

[0027] When in use, the stepper motor 111, the first electric push rod 22 and the second electric push rod 4 are all connected to the control device, and the laser welding gun 32 is connected to the laser welding machine, and the connecting line is passed through the opening 21. When the oil pipe needs to be welded, the second electric push rod 4 is first used to drive the lifting plate 41 and the positioning plate 411 to rise. The positioning plate 411 is located directly below the welding head of the laser welding gun 32. Then, the oil pipe to be welded together is supported between the lower guide wheels 11 at the front and rear ends of both sides, and the end of the oil pipe is brought close to the positioning plate 411 in the middle position and contacts the surface of the positioning plate 411. The thickness of the positioning plate 411 is used to limit the size of the gap between the oil pipes. Then, the first electric push rod 22 is controlled to drive the pressure plate 3 to descend, so that the laser The welding gun 32 and the upper guide wheel 31 are both lowered, and the upper guide wheel 31 is pressed on the surface of the pipes on both sides to press the pipes tightly. The welding head part of the laser welding gun 32 is close to the weld position of the oil pipe. Then, the second electric push rod 4 is controlled to drive the lifting plate 41 to lower the height and pull the positioning plate 411 downward. Then, the laser welding gun 32 is started and the stepper motor 111 is started at the same time to drive the lower guide wheel 11 at the front end to rotate, and the oil pipes on both sides are driven to rotate synchronously, and then the welding head of the laser welding gun 32 can be used to weld the oil pipes together. After welding is completed, the rotation of the stepper motor 111 and the operation of the laser welding gun 32 are stopped, and the first electric push rod 22 drives the pressure plate 3, the upper guide wheel 31 and the laser welding gun 32 to rise, and then the welded oil pipe can be taken away.
