Description

Technical Field

[0001] This utility model relates to the field of head welding technology, specifically a high-sealing heat exchanger head welding device. Background Technology

[0002] A high-sealing heat exchanger is a heat exchange device specifically designed for high-temperature, high-pressure, or corrosive media. High-sealing heat exchangers are typically tubular. During the heat exchanger manufacturing process, end caps are usually welded to both ends of the tube body to seal the ends. However, existing high-sealing heat exchanger end cap welding devices often have issues. Since some end caps are hemispherical, manual alignment of the end caps with the pipe ends is required during welding. This involves first welding the end caps to the pipe at multiple points, followed by full welding. However, manual alignment may introduce deviations, potentially affecting the subsequent sealing effect and the quality of the heat exchanger. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4In this embodiment of the present invention, a high-sealing heat exchanger head welding device includes a support base 100, two adjustment modules 200 and two drive modules 400. A welding frame 110 is provided on the top of the support base 100, and a welding head is provided on the welding frame 110. The welding frame 110 can be slidably placed on the top of the support base 100, so that the position of the welding frame 110 can be adjusted to weld the two ends of the heat exchanger tube in sequence. Four clamping seats 300 are provided between the two adjustment modules 200. The adjustment module 200 includes a connecting frame 210. Both ends of the clamping seat 300 are fixedly connected to sliding blocks 330 that are slidably connected to the inside of the connecting frame 210. The side of the connecting frame 210 is provided with a strip groove that is slidably connected to the end of the adjacent clamping seat 300.

[0029] The clamping seat 300 has several threaded holes 310 on its side. The clamping seat 300 is provided with a threaded rod 320 that engages with adjacent threaded holes 310. A ball seat 321 is fixedly connected to the end of the threaded rod 320. A drive module 400 is mounted on the adjustment module 200, with two drive modules 400 located between two adjustment modules 200. The drive modules 400 are located between the four clamping seats 300. A fixing frame 120 is fixedly connected to the inner side of the support seat 100. The fixing frame 120 contains... A support frame 130 is slidably connected to the side. The top of the support frame 130 extends between four clamping seats 300. Several hydraulic rods 121 are fixedly connected to the bottom surface of the fixed frame 120. The output end of the hydraulic rods 121 is connected to the top surface of the support frame 130. A limit ring is fixedly connected to the side of the threaded rod 320. The limit ring can abut against the side of the sliding block 330. The position of the threaded rod 320 is restricted by the limit ring, so that several ball seats 321 in the middle of the clamping seat 300 are aligned, which facilitates the clamping of the pipe.

[0030] Specifically, the heat exchanger tube can be moved to the top of the support frame 130, and then the support frame 130 can be moved upward by the hydraulic rod 121. The support frame 130 can lift the tube upward, so that the top of the support frame 130 and the tube pass between the two bottom clamping seats 300, and the heat exchanger tube is moved between the four clamping seats 300. Then, the end cap is roughly aligned with the end of the tube, so that the clamping seats 300 can move along the strip groove, so that the four clamping seats 300 move towards each other. The clamping seats 300 can drive the threaded rod 320 to move, so that the spherical seat 3... The ball on 21 rests against the tube body and the end cap. The tube body is supported by the ball seat 321 in the middle of the clamping seat 300. The ball seats 321 at the ends of the four clamping seats 300 rest against the arc surface of the end cap, so that the ball seats 321 limit the end cap and align the end cap with the tube body. The ball seats 321 can also tightly press the end cap against the tube body, which facilitates the subsequent welding of the tube body and the end cap. The ball seats 321 clamp the end cap and the tube body, which is conducive to the accurate alignment of the end cap and the tube body and helps to ensure the welding effect.

[0031] The positions of the threaded rod 320 and the ball seat 321 at the end of the clamping seat 300 can be adjusted according to the size of the end cap, thereby adapting to the fixing of end caps of different sizes. At the same time, when the pipe length is small, the threaded rod 320 can be screwed into the threaded hole 310 of the corresponding end cap, and the position of the threaded rod 320 can be adjusted according to the size of the end cap, so that the ball seat 321 on the threaded rod 320 abuts against the end cap, supporting and positioning the end cap, which is convenient for clamping pipes of different lengths.

[0032] Example 1

[0033] like Figure 3 and Figure 5 As shown, in this embodiment, the sliding block 330 is fixedly connected with a toothed rod 331. The toothed rods 331 on the two diagonally opposite sliding blocks 330 are in one group, and the two groups of toothed rods 331 are staggered.

[0034] The adjustment module 200 also includes an adjustment motor 240, a power box 220, and a connecting shaft 230;

[0035] The adjusting motor 240 is mounted on the connecting frame 210 and is located on the side of the connecting frame 210 away from the drive module 400. The power box 220 is fixedly connected to the connecting frame 210, and the adjusting motor 240 is fixedly mounted inside the power box 220. The power box 220 can provide some shielding for the adjusting motor 240. The output end of the adjusting motor 240 is connected to the end of the connecting shaft 230. The side of the connecting shaft 230 is fixedly connected to a connecting gear 231 that meshes with four racks 331. The end of the connecting shaft 230 is rotatably connected to the inner side of the connecting frame 210. The inner side of the connecting frame 210 is fixedly connected to several limiting rods 211 that slide with adjacent racks 331. The limiting rods 211 restrict the movement direction of the racks 331, so that the racks 331 remain meshed with the connecting gears 231.

[0036] In practice, after the heat exchanger tube is moved between the four clamping seats 300, the connecting shaft 230 can be rotated by adjusting the motor 240. The connecting shaft 230 can rotate the connecting gear 231, which can move the four racks 331. The racks 331 can move the clamping seats 300 through the sliding block 330, thereby causing the four clamping seats 300 to move towards each other and clamp the heat exchanger tube and the end cap.

[0037] like Figure 3 As shown, in this embodiment, the drive module 400 includes a fixed base 410, an L-shaped base 420, and a connecting pipe 430;

[0038] The fixed base 410 is fixedly connected to the connecting frame 210, and the L-shaped base 420 is slidably connected to the fixed base 410. The L-shaped base 420 can slide along the inside of the fixed base 410. The connecting frame 210 can position the fixed base 410 and the L-shaped base 420. The connecting tube 430 is rotatably connected to the L-shaped base 420. A suction cup 431 is fixedly connected to the end of the connecting tube 430. The suction cup 431 is located on the side of the connecting tube 430 away from the fixed base 410. An electric telescopic rod 411 is provided inside the fixed base 410. The output end of the electric telescopic rod 411 is connected to the L-shaped base 420 in a transmission connection.

[0039] In practice, the connecting pipe 430 can be connected to a negative pressure generator, which is then connected to a gas source. The negative pressure generator creates negative pressure inside the connecting pipe 430. After the end cap is placed against the suction cup 431, the suction cup 431 can hold the end cap in place. Once the tube body is moved between the four clamping seats 300, the L-shaped seat 420 can be moved by the electric telescopic rod 411. The L-shaped seat 420 can then move the connecting pipe 430, which in turn can move the end cap through the suction cup 431, moving it to the end of the tube body. Then, the four clamping seats 300 can move towards each other to clamp the end cap and the tube body. At this point, the suction cup 431 can release the end cap, and the spherical seat 321 can be used to position and clamp the end cap, ensuring that the end cap and the tube body are aligned as much as possible.

[0040] Example 2

[0041] Based on Example 1, such as Figure 3 As shown, in this embodiment, a drive motor 421 is fixedly installed inside the L-shaped seat 420. The output end of the drive motor 421 is connected to a drive shaft 422. Both the drive shaft 422 and the connecting pipe 430 are fixedly sleeved with transmission gears 440, and the two transmission gears 440 mesh and drive each other. The end of the connecting pipe 430 is rotatably connected to a fixed pipe 432. The fixed pipe 432 can be connected to a negative pressure generator through a hose, so that the connecting pipe 430 is connected to the negative pressure generator through the fixed pipe 432 and the hose. The end of the drive shaft 422 is rotatably connected to the inner side of the L-shaped seat 420, and the side of the fixed pipe 432 is fixedly connected to the inner side of the L-shaped seat 420. The L-shaped seat 420 restricts the position of the fixed pipe 432.

[0042] In practice, after the clamping seat 300 clamps the tube body, the suction cup 431 can hold the end cap. Then, the drive motor 421 can drive the drive shaft 422 to rotate. The drive shaft 422 can drive the connecting pipe 430 to rotate through the transmission gear 440, so that the connecting pipe 430 rotates relative to the fixed pipe 432. The connecting pipe 431 can push the end cap to rotate. Since the end cap is tightly pressed against the tube body, the end cap can push the tube body to rotate, so that the end cap and the tube body rotate between several ball seats 321, so that the welding head can fully weld the end cap and the tube body.
