The sealing portion 21 and the sleeve body 22 are two parts formed after cutting the sleeve 2, so as to facilitate the installation of the temperature sensing component. The upper outer wall of the sealing portion 21 is spherical, and the lower outer wall is cylindrical. The sleeve body 22 is cylindrical, and the upper end surface of the sleeve body 22 is welded to the lower end surface of the sealing portion 21.

[0024] like Figure 1 , Figure 2 As shown, the ultrasonic welding tool comprises a bottom sleeve 1, and the bottom sleeve 1 is provided with a countersunk hole 11 in the axial direction. The diameter of the countersunk hole 11 is larger than the outer diameter of the sleeve 2, so as to facilitate the insertion of the sleeve 2, and the sealing part 21 and the pipe sleeve body 22 can be adjusted in the radial direction of the countersunk hole 11 in the countersunk hole 11, so as to facilitate the alignment of the outer walls of the two. The hole 11 extends downward from the upper end of the bottom sleeve 1. When welding, the sealing part 21 and the pipe sleeve body 22 are inserted into the countersunk hole 11, and the upper end of the pipe sleeve body 22 is located below the top of the countersunk hole 11, and the upper end of the sealing part 21 extends out of the top of the countersunk hole 11. After the outer walls of the sealing part 21 and the pipe sleeve body 22 are flushed up and down, the pressure head 4 of the ultrasonic welding machine presses the top of the sealing part 21 and performs the welding operation, and the sealing part 21 and the pipe sleeve body 22 are fixed by ultrasonic waves.

[0025] Combination Figure 3 , groove bodies 12 are provided on both sides of the bottom sleeve 1, and the groove bodies 12 are arranged near the top of the bottom sleeve 1. The groove bodies 12 pass through the outer wall of the bottom sleeve 1, and the groove bodies 12 are connected with the radial outer end of the countersunk hole 11. The groove body 12 includes a wall surface 121 and a wall surface 122. The wall surface 121 is an arc shape, and the wall surface 122 is located away from the side connected with the countersunk hole 11. The wall surface 121 is located between the connecting end of the wall surface 122 and the groove body 12 connected with the countersunk hole 11, and the wall surface 122 is concentric with the ring body 5.

[0026] like Figure 2 As shown, the ultrasonic welding tool also includes a ring body 5, the bottom sleeve 1 passes through the ring body 5, and the ring body 5 can rotate along its own axis. Specifically, the bottom sleeve 1 is equipped with a support seat 6, the bottom of the ring body 5 is inserted into the support seat 6, and the ring body 5 can rotate along the inner wall of the support seat 6. The inner wall of the support seat 6 fits the radial outer wall of the ring body 5 to limit the rotation of the ring body 5.

[0027] like Figure 3 As shown, the two sides of the ring body 5 are slidably connected with slide rods 3, and the slide rods 3 can move radially along the ring body 5. The slide rods 3 are installed with sleeves 34. Figure 4 The slide bar 3 is provided with grooves 32 on both sides of the axis, and the sleeve 34 includes a support rod 341, which is inserted into the groove 32 and fixed, and the support rod 341 extends out of the radial outer end of the slide bar 3. The support rod 341 is located between the bottom sleeve 1 and the ring body 5, and the slide bar 3 is sleeved with a spring 33, one end of the spring 33 abuts against the ring body 5, and the other end of the spring 33 abuts against the support rod 341.

[0028] like Figure 5 As shown, the slide bar 3 includes an end portion 31 close to the bottom sleeve 1, the end portion 31 is inserted into the groove body 12, and the end portion 31 is provided with an end second portion 312. The slide bar 3 moves close to the bottom sleeve 1 to be inserted into the countersunk hole 11, so that the end second portion 312 is located in the countersunk hole 11, and the end second portion 312 is arc-shaped, and the center of the end second portion 312 is located in the countersunk hole 11. Figure 2 The upper part of the inner wall of the second end part 312 is in contact with the outer wall of the lower part of the sealing part 21, and the lower part of the inner wall of the second end part 312 is in contact with the outer wall of the sleeve body 22. The second end parts 312 on both sides clamp the sealing part 21 and the sleeve body 22 under the action of the spring 33, and align the outer walls of the sealing part 21 and the sleeve body 22 up and down to improve the matching accuracy of the sealing part 21 and the sleeve body 22 during welding.

[0029] like Figure 5 As shown, the end portion 31 is further provided with an end portion 311. When the ring body 5 rotates, the end portion 311 can slide along the wall surface 121 to make the end portion 312 leave the counterbore 11, and the ring body 5 rotates. Figure 6 When the second end portion 312 moves to the second wall surface 122, the second end portion 312 abuts against the second wall surface 122. At this time, the second end portion 312 is located outside the countersunk hole 11, so as to facilitate the insertion of the sealing portion 21 and the tube sleeve body 22 into the countersunk hole 11. When the second end portions 312 on both sides extend into the countersunk hole 11 and clamp the sealing portion 21 and the tube sleeve body 22, the pressure head 4 moves downward to press the top of the sealing portion 21, and then the second end portion 312 is moved out of the countersunk hole 11, and the ultrasonic welding machine is started to weld the sealing portion 21 and the tube sleeve body 22.
