Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe welding, in particular to a butt joint assisting device for stainless steel pipe welding. Background Art

[0002] Stainless steel pipe is a hollow, long, round steel material, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. In addition, when the bending and torsional strengths are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used as furniture and kitchen utensils. In order to cope with different usage environments, stainless steel pipes need to be welded.

[0003] Currently, most stainless steel pipe welding is done manually, which requires high proficiency of workers. In addition, the manual docking method is inefficient and cannot accurately measure the distance between two transversely welded steel pipes, resulting in low accuracy. Utility Model Content

[0004] The purpose of the utility model is to provide a butt joint assisting device for stainless steel pipe welding in view of the deficiencies of the prior art, so as to solve the problems raised in the background technology.

[0005] The top of described sliding panel also is provided with an end face that is provided with an end face of steps in advance, and the sliding panel also is provided with an end face having a circle, and the two end faces of sliding panel withstands on the back of the sliding panel.

[0006] As an optimal technical solution of the present invention, there are two fixing clamps, the upper ends of which are movably connected to each other. When the two fixing clamps are driven to connect at the top, they clamp the steel pipe in a ring shape, so that the steel pipes to be welded can be butt-jointed, ensuring the accuracy of the butt joint.

[0007] As an optimal technical solution of the present invention, a clamping block is provided at the bottom end of the two pads, and a slide groove is provided at the top of the base on the outer surface of the clamping block. The clamping block and the slide groove are used in conjunction with each other to limit the pad so that the pad will not deviate when being driven to perform linear motion, thereby ensuring the stability of the equipment.

[0008] As a preferred technical solution of the present invention, the bottom ends of the two second electric push rods are hingedly mounted on the top of the pad to fix the second electric push rods, ensuring that the output ends of the two electric push rods can drive the corresponding fixing clamps to perform flipping movement.

[0009] As an optimal technical solution of the present invention, a placement hole is provided through the middle position of one side of the two support plates. The placement hole is used to place the main steel pipe. When the two steel pipes are welded, the other steel pipe is in a vertical state with the steel pipe inserted into the placement hole, which is convenient for docking. After the welding of the steel pipes is completed, the pressure plate is pulled up and down to make the top of the placement hole open, and the welded steel pipe can be taken out.

[0010] As an optimal technical solution of the present invention, the bottom end of the pad is movably connected to the top end of the base, so that the pad can slide on the top end of the base, so that the stainless steel pipe can adjust the welding position and improve welding efficiency.

[0011] The beneficial effects of the utility model are:

[0012] 1. This kind of stainless steel pipe welding butt joint assisting device can firmly fix the stainless steel pipe to be welded in the required position, ensuring that there will be no shaking during welding and reducing the difficulty of welding.

[0013] 2.

[0021] like Figure 1-4As shown, in this embodiment: a butt joint assisting device for stainless steel pipe welding, comprising a base 1, two support plates 2 are provided at the edges of both sides of the top of the base 1, and the tops of the two support plates 2 are both plugged with a lower pressure plate 16, and the two support plates 2 protect the top of the base 1 to reduce the range of debris splashing during welding, and two first first electric push rods 5 are provided at the top of the base 1 between the two support plates 2, and the output ends of the two first first electric push rods 5 are both provided with a pad 9, and two scale grooves 6 are provided at the top of the base 1 near the position of the two first first electric push rods 5, and the bottom ends of the two pads 9 are both provided with a card block 7, and a slide groove 4 is provided on the outer surface of the card block 7 at the top of the base 1, and a scale pointer 10 is provided at one end of the pad 9 near the position of the scale groove 6, and the pad 9 is driven by the first electric push rod 5 to perform linear motion to adjust the position of the steel pipe to be welded. When the first electric push rod 5 drives the pad 9 to run, the movement distance of the pad 9 is the scale pointed to by the scale pointer 10. Two support columns 15 are fixed on the top of the pad 9. The tops of the two support columns 15 are commonly connected to the opening and closing shaft 14. The outer surface of the opening and closing shaft 14 is hingedly installed with two fixing clamps 8. A connecting plate 11 is provided on one side of the two fixing clamps 8. A rotating column 12 is provided inside the two connecting plates 11. The outer surface of the rotating column 12 is connected to the second electric push rod 13. The output ends of the two second electric push rods 13 drive the two fixing clamps 8 to perform a flipping motion with the opening and closing shaft 14 as the center of the circle to achieve the effect of clamping or loosening the steel pipe.

[0022] Furthermore, there are two fixing clamps 8, and the upper ends of the fixing clamps 8 are movably connected to each other. When the two fixing clamps 8 are driven to connect at the top, they clamp the steel pipe in a ring shape, so that the steel pipes to be welded can be butt-jointed, ensuring the accuracy of the butt joint.

[0023] Furthermore, a clamping block 7 is provided at the bottom end of each of the two pads 9, and a slide groove 4 is provided at the top of the base 1 on the outer surface of the clamping block 7. The clamping block 7 and the slide groove 4 are used in conjunction with each other to limit the pad 9 so that the pad 9 will not deviate when being driven to perform linear motion, thereby ensuring the stability of the equipment.

[0024] Furthermore, the bottom ends of the two second electric push rods 13 are hingedly mounted on the top of the pad 9 to fix the second electric push rods 13, ensuring that the output ends of the two second electric push rods 13 can drive the corresponding fixing clamps 8 to perform flipping motion.

[0025] Furthermore, a placement hole 3 is provided through the middle position of one side of each of the two support plates 2. The placement hole 3 is used to place the main steel pipe. When the two steel pipes are welded, the other steel pipe is in a vertical state with the steel pipe inserted into the placement hole 3, which is convenient for docking. After the steel pipe welding is completed, the lower pressure plate 16 is pulled up to open the top of the placement hole 3 so that the welded steel pipe can be taken out.

[0026] Furthermore, the bottom end of the pad 9 is movably connected to the top end of the base 1, so that the pad 9 can slide on the top end of the base 1, so that the welding position of the stainless steel pipe can be adjusted, thereby improving welding efficiency.

[0027] The method of using this embodiment is as follows: Figure 1-4 When using the docking assistant for stainless steel pipe welding, first insert the main steel pipe to be welded into the placement hole 3, and then start the second electric push rod 13. The second electric push rod 13 is connected to the outer surface of the fixing clamp 8 through the connecting plate 11, so the fixing clamp 8 will be pulled open, and then the stainless steel pipe to be welded is placed inside the fixing clamp 8, and then the second electric push rod 13 is started to push the fixing clamp 8 closed to clamp the steel pipe. The pad 9 is driven by the first electric push rod 5 to move parallel. The pad 9 is connected to the surface of the base 1 through the clamping block 7, so the pad 9 will not deviate during the movement, and the scale pointer 10 set on the surface of the pad 9 can intuitively see the welding position of the steel pipe, ensuring that the stainless steel pipe can be docked at the required position.

[0028] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them.
