DETAILED DESCRIPTION

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a pipe connector welding tool, including a tooling table 1, a through opening 2 is opened on the tooling table 1, and an arc positioning seat 3 is fixedly installed on the top of the tooling table 1, and two groups of arc positioning seats 3 are provided. The two groups of arc positioning seats 3 are mirror-imaged and arranged on the top of the tooling table 1 with the through opening 2 as the central axis. The side walls of the two groups of arc positioning seats 3 are slidably connected with L rods 53, and a three-way pipe 4 is placed on the arc positioning seat 3. The main pipe of the three-way pipe 4 is placed on the arc positioning seat 3, so that the branch pipe of the three-way pipe 4 faces downward and is placed in the through opening 2. A positioning mechanism 5 for convenient positioning of the three-way pipe 4 is provided on the tooling table 1. By setting the positioning mechanism 5, the three-way pipe 4 can be quickly positioned, which is more convenient to use. The positioning mechanism 5 is provided with an adjustment mechanism 6 that can adapt to different pipe diameters. By setting the adjustment mechanism 6, the three-way pipes 4 with different pipe diameters can be positioned, which is more practical.

[0024] The positioning mechanism 5 comprises a bidirectional screw rod 51, a slide plate 52, an L rod 53, a knob 54, a transverse sleeve 55, a longitudinal sleeve 56 and a connecting rod 57; one end of the bidirectional screw rod 51 is rotatably connected to the inner wall of the through-port 2, and the other end of the bidirectional screw rod 51 passes through the tooling table 1 and is fixedly installed with a knob 54, the bidirectional screw rod 51 is rotatably connected to the through-port of the tooling table 1, and the outer wall of the bidirectional screw rod 51 is threadedly connected with two groups of slide plates 52, and the side walls of the slide plates 52 are fitted with the inner wall of the through-port 2. The bidirectional screw rod 51 is rotated by rotating the knob 54, and the rotation of the bidirectional screw rod 51 cooperates with the limit of the through-port 2, so that the two groups of slide plates 52 can be synchronously moved in opposite directions, and a transverse sleeve 55 is fixedly installed on the top of the slide plate 52, and the two groups of slide plates 52 are brought close to each other and cooperate with the transverse sleeve 55 to clamp the branch pipe of the tee pipe 4, so that the branch pipe of the tee pipe 4 can be adjusted. The L rod 53 is fixed, and the L rod 53 is slidably connected to the side wall of the arc positioning seat 3. A longitudinal jacket 56 is fixedly installed on the top of the L rod 53. The longitudinal jacket 56 and the transverse jacket 55 are all arc-shaped with the top of the arc positioning seat 3, and the longitudinal jacket 56 and the transverse jacket 55 are equal to the arc radius of the arc positioning seat 3. The longitudinal jacket 56 is driven downward by the L rod 53 to fit the top of the arc positioning seat 3. At this time, the main pipe of the tee pipe 4 can be positioned by using the longitudinal jacket 56 in conjunction with the arc positioning seat 3. A connecting rod 57 is hinged on the side wall of the L rod 53. One end of the connecting rod 57 away from the L rod 53 is hinged on the side wall of the slide plate 52. When the two groups of slide plates 52 approach each other, the slide plate 52 will pull the connecting rod 57, so that the connecting rod 57 pulls the L rod 53, so that the L rod 53 can slide downward on the side wall of the arc positioning seat 3.

[0025] The above-mentioned adjusting mechanism 6 includes a longitudinal bolt 61, a longitudinal clamping plate 62, a transverse bolt 63, and a transverse clamping plate 64; the longitudinal bolt 61 is threadedly connected to the inner wall of the longitudinal jacket 56, and the longitudinal bolt 61 penetrates the longitudinal jacket 56 and is rotatably connected to the longitudinal clamping plate 62. The longitudinal bolt 61 is rotated to make the longitudinal bolt 61 move downward on the inner wall of the longitudinal jacket 56. At this time, the longitudinal bolt 61 will drive the longitudinal clamping plate 62 to move downward synchronously. At this time, the main pipe of the tee pipe 4 can be fixed by using the longitudinal clamping plate 62 in conjunction with the arc positioning seat 3. The inner wall of the transverse jacket 55 is threadedly connected with a transverse bolt 63, and the transverse bolt 63 penetrates the transverse jacket 55 and is fixedly installed with a transverse clamping plate 64. The transverse bolt 63 is rotated to make the transverse bolt 63 drive the transverse clamping plate 64 to fit the outer wall of the tee pipe 4. The transverse bolts 63 and the transverse clamping plates 64 on the two groups of transverse jackets 55 can be used to fix the branch pipe of the tee pipe 4, so as to adapt to the tee pipes 4 of different pipe diameters.

[0026] Working principle: first place the main pipe of the tee pipe 4 on the arc positioning seat 3, so that the branch pipe of the tee pipe 4 faces downward and is placed in the opening 2, and then rotate the bidirectional screw rod 51 through the knob 54. Through the rotation of the bidirectional screw rod 51 and the limit of the opening 2, the two sets of slide plates 52 can be moved synchronously in opposite directions and approach each other, so that the transverse jackets 55 on the two sets of slide plates 52 clamp the branch pipe of the tee pipe 4, so that the branch pipe of the tee pipe 4 can be fixed. At the same time, the two sets of slide plates 52 When approaching each other, the slide plate 52 will pull the connecting rod 57, so that the connecting rod 57 pulls the L rod 53, so that the L rod 53 can slide downward on the side wall of the arc positioning seat 3. At this time, the L rod 53 will drive the longitudinal jacket 56 to move downward synchronously, and make the longitudinal jacket 56 fit on the top of the arc positioning seat 3. At this time, the longitudinal jacket 56 can be used in conjunction with the arc positioning seat 3 to position the main pipe of the tee pipe 4, so that the branch pipe and the main pipe of the tee pipe 4 can be fixed synchronously, which is more convenient to use.

[0027] When the diameter of the tee pipe 4 is smaller than the inner diameter of the arc positioning seat 3, first use the transverse sleeve 55 to cooperate with the longitudinal sleeve 56 and the arc positioning seat 3 to position the main pipe and branch pipe of the tee pipe 4, and then rotate the longitudinal bolt 61 to make the longitudinal bolt 61 move downward on the inner wall of the longitudinal sleeve 56. At this time, the longitudinal bolt 61 will drive the longitudinal clamping plate 62 to move downward synchronously, and make the longitudinal clamping plate 62 fit the outer wall of the tee pipe 4. At this time, the main pipe of the tee pipe 4 can be fixed by using the longitudinal clamping plate 62 in cooperation with the arc positioning seat 3, and then rotate the transverse bolt 63 to make the transverse bolt 63 drive the transverse clamping plate 64 to fit the outer wall of the tee pipe 4. At this time, the transverse bolts 63 and transverse clamping plates 64 on the two sets of transverse sleeves 55 can be used to fix the branch pipe of the tee pipe 4, so as to adapt to the tee pipes 4 of different diameters, which is more practical.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
