[0001] The utility model relates to the technical field of mechanical manufacturing, and particularly relates to an adjustable straight seam welding machine suitable for the processing of pipe fittings seals. Background Art

[0002] In modern industrial production, pipe fittings are widely used and crucial. Pipe fittings undertake the task of transporting important substances such as liquids and gases in many fields, such as petroleum, chemical industry, construction, etc. The sealing performance of pipe fittings is directly related to the safe and stable operation of the entire system.

[0003] However, in the prior art, the welding head of traditional welding equipment is usually fixed and cannot be adjusted. Therefore, when welding pipe fitting seals, if the welding position is incorrect, the seal can only be clamped again to change the welding position, which is not convenient for the staff to carry out welding work. In addition, traditional welding equipment usually uses a bench vice type clamping mechanism to clamp the seal. When clamping the seal, it is necessary to frequently rotate the screw rod of the bench vice to disassemble and assemble the seal, thus increasing the working time of the staff.

[0020] One end of the extension spring 56 away from the insertion block 55 is fixedly connected to the top of the mounting frame 51. The top of the mounting frame 51 is slidably connected to the outer wall of the bottom of the insertion block 55 through a fixed sleeve. The top of the welding head 58 is fixedly connected to a handle 54. The clamping mechanism 4 includes a clamping plate 41. A roller 42 is slidably connected to the inner wall of the clamping plate 41, and the rollers 42 are linearly arranged along the outer wall of the clamping plate 41. A top spring 44 is fixedly connected to the outer wall of the clamping plate 41. There are two groups of top springs 44. A pull handle 45 is fixedly connected to one side of the clamping plate 41 away from the roller 42. By the sliding of the roller 42, the position of the sealing clip can be changed. A connecting handle 46 is slidably connected to the inner wall of the frame 1, and a clamping block 47 is fixedly connected to the outer wall of the connecting handle 46.

[0021] The outer wall of the clamping block 47 is fixedly connected to the inner wall of the frame 1, driving the outer wall of the clamping block 47 to be clamped with the inner wall of the pull handle 45 through a clamping groove 48, and the clamping groove 48 is opened in the walls on both sides of the pull handle 45. By pulling the connecting handle 46, the two clamping blocks 47 can be driven to expand in a direction away from the pull handle 45. A limiting column 43 is fixedly connected to the inner wall of the frame 1, and the outer wall of the limiting column 43 is in contact with the outer wall of the top spring 44. One end of the top spring 44 away from the clamping plate 41 is fixedly connected to the inner wall of the frame 1. The outer wall of the pull handle 45 is slidably connected to the inner wall of the frame 1.

[0022] Working principle:

[0023] When in use, first place the frame 1 on the ground. After the frame 1 is placed stably, the welding work on the pipe fitting seal can be started. Place the seal from the opening on the frame 1 on the working plate 3. Then pull the clamping mechanism 4, so that the clamping mechanism clamps the seal on the working plate 3, restricting the position of the seal. After the position of the seal is fixed, the position of the welding head 58 can be adjusted through the adjusting mechanism 5. After the welding head 58 is positioned at the place where the seal needs to be welded, an external welding device can be started, and the welding head 58 slides along the limiting rod 2 to perform linear welding work on the seal.

[0024] Before placing the seal on the working plate 3, it is necessary to first pull the handles 45 on both sides of the frame 1. By pulling the handles 45, the clamping plates 41 are driven to slide towards the inner wall of the frame 1. When the card slot 48 on the handle 45 slides to the position of the latch 47 and the latch 47 is snapped into the card slot 48, the position of the handle 45 is restricted, and then the position of the clamping plate 41 is restricted. Then, the seal can be placed on the working plate 3. After the seal is placed on the working plate 3, the connecting handle 46 can be pulled, thereby driving the latch 47 to expand outwards, causing the latch 47 to disengage from the card slot 48. Because during the sliding process of the handle 45 before, the top spring 44 on the limit post 43 was simultaneously compressed, causing the top spring 44 to accumulate elastic potential energy. Therefore, when the latch 47 releases the lock on the handle 45, the top spring 44 releases the elastic potential energy, thereby pushing the clamping plate 41 to slide towards the working plate 3, and the seal on the working plate 3 can be clamped by the two clamping plates 41. The rollers 42 on the clamping plate 41 are used to synchronously change the position of the seal during the process of clamping the seal, so that the seal can be clamped at the center of the clamping plate 41.

[0025] After the position of the seal is clamped, the position of the welding head 58 can be adjusted next, so that the welding head 58 is at the position where welding is required. Just pull up the insertion block 55 upwards, so that the insertion block 55 slides out of the limit hole 53 in the limit disk 52, and the lock on the limit disk 52 can be released. Then, by turning the handle 54 on the limit disk 52, the limit disk 52 can be driven to rotate in a circular motion, and then the welding head 58 is driven to rotate. When the welding head 58 rotates to the required position, the pulling force on the insertion block 55 can be released.

[0026] Because during the process of pulling the insertion block 55 before, the tension spring 56 on the insertion block 55 was simultaneously stretched, causing the tension spring 56 to accumulate elastic potential energy. Therefore, when the pulling force on the insertion block 55 is released, the tension spring 56 releases the elastic potential energy, thereby driving the insertion block 55 to slide back into the limit hole 53 in the limit disk 52. And because the insertion block 55 is connected to the installation frame 51 and the insertion block 55 can only slide up and down, the position of the limit disk 52 can be restricted again, and then the position of the welding head 58 can be restricted. Then, the sliding frame 57 can be pushed along the limit rod 2 to perform linear welding work on the seal.

[0027] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art without special instructions and limitations.
