DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example: Reference Figure 1-7A branch pipe press-fitting device for a carbon steel pipe assembly shown in the figure includes a bottom plate 1. On the top surface of the bottom plate 1, there are two groups of symmetric reciprocating cylinders 2. A pressure seat 3 is provided at the telescopic end face of the reciprocating cylinder 2. And in the direction of the telescopic end of the reciprocating cylinder 2, a positioning assembly 9 for placing a copper branch pipe 8 and a supporting assembly 6 for placing a steel pipe 7 are arranged in sequence. And in order to keep the state of the steel pipe 7 stable, a positioning bracket 4 is provided on one side of the supporting assembly 6. An adjustable positioning member 5 is slidably connected to the positioning bracket 4.

[0027] The positioning bracket 4 is a U-shaped member, and a lifting groove 41 is provided thereon, and the shape is "middle" shaped. A lifting block 51 of the adjustable positioning member 5 is slidably connected in the lifting groove 41. The lifting block 51 and the lifting groove 41 are adapted to each other, and a damping pad is provided between the two, which is convenient for height positioning after adjusting the height. A hole is provided in the lifting block 51, and an adjusting rod 52 is threadedly connected in the hole. The adjusting rod 52 adjusts the extending length in the hole, and a positioning head 53 is provided at the end face facing the supporting assembly 6. The positioning head 53 is conical to assist in positioning the steel pipe 7 placed on the supporting assembly 6.

[0028] Supporting assembly 6: A support plate 61 is provided on the top surface of the bottom plate 1, and a through hole 62 is provided on the support plate 61. A support seat 63 is slidably connected between the support plate 61 and the positioning assembly 9. And an adjusting distance rod 65 is rotatably connected to the outer wall of the support seat 63. The adjusting distance rod 65 is threadedly connected with the through hole 62, and its function is to adjust the distance between the support plate 61 and the support seat 63. A placing inclined surface 64 is provided at the top edge of the support seat 63 (as shown in Figure 4 、 5 shown). Through the cooperation of the above structures, the distance between the support plate 61 and the support seat 63 is controlled to become larger, so that it can be adapted to various specifications of steel pipes 7; in order to make the positioning assembly 9 adjust synchronously, the support seat 63 is connected to the positioning assembly 9 through a synchronizing member 10.

[0029] Positioning assembly 9: A base 91 is provided on the top surface of the bottom plate 1, and the shape of the base 91 is wedge-shaped. A slide rail 92 is provided on the inclined surface of the base 91. Every two slide rails 92 are in a group, and the slide rail 92 is a T-shaped structure. The sliding seat 93 is an L-shaped structure, and its bottom is provided with an inclined surface adapted to the base 91. And a T-shaped chute 94 is provided on the inclined surface of the sliding seat 93. The chute 94 and the slide rail 92 are adapted to each other, and they cooperate with each other. Under the action of the synchronizing member 10, it moves downwards following the movement of the support seat 63. A positioning seat 95 is fixed on the top surface of the sliding seat 93 by bolts. The positioning seat 95 is an E-shaped member, and the groove provided thereon is used to place the copper branch pipe 8 to make the copper branch pipe 8 dock with the connection hole on the steel pipe 7.

[0030] The synchronizer 10 is arranged on the outer wall of the support seat 63, and a waist-shaped synchronizer groove 11 is provided on the outer wall of the positioning seat 95. When the above-mentioned support seat 63 moves, the protrusion at the end of the synchronizer 10 climbs and moves in the synchronizer groove 11, thereby driving the slide seat 93 to slide down on the slide rail 92.

[0031] In order to further stabilize the steel pipe 7 placed on the support assembly 6, a tightening piece 13 is threadedly connected to the outer wall of the support seat 63, and an auxiliary plate 12 is slidably connected to the tightening piece 13 (when in use, first loosen the tightening piece 13 outward, rotate the auxiliary plate 12 180 degrees, and then tighten the tightening piece 13 again), and a support plate 14 is connected to the auxiliary plate 12 by bolts. Therefore, when the bolt on the support plate 14 is rotated (the support plate 14 is rotationally connected to the bolt), the movement of the support plate 14 is controlled so that the end face of the support plate 14 is against the connecting hole of the steel pipe 7, so that it is in a parallel state.

[0032] The practical working principle of the present invention is as follows: according to the specifications of the steel pipe 7, the pitch-adjusting rod 65 is rotated, and the pitch-adjusting rod 65 rotates in the perforation 62, driving the support seat 63 to move, thereby expanding the distance between the support plate 61 and the support seat 63. After completion, the steel pipe 7 is placed on the placement inclined surface 64, and then according to the position of the steel pipe 7, the lifting block 51 of the adjustable positioning member 5 is moved to make it rise and fall in the lifting groove 41 of the positioning bracket 4. After this process, the positioning head 53 is aligned with the center of the circle of the steel pipe 7, and the adjusting rod 52 is rotated to complete the positioning of the steel pipe 7. After completing the above operation, the tensioning member 13 is rotated to make the auxiliary plate 12 in an active state, and then the auxiliary plate 12 is rotated 180 degrees, and the tensioning member 13 is tightened again, and then the auxiliary plate 12 is rotated Bolt, move the abutment plate 14 toward the connecting hole of the steel pipe 7, so that the abutment plate 14 abuts against the connecting hole, and completes the positioning of the steel pipe 7; when performing the above operation, the moving support seat 63 pushes the positioning seat 95 through the cooperation between the synchronous member 10 and the positioning assembly 9 (the synchronous member 10 slides in the synchronous groove 11), and the positioning seat 95 moves on the base 91 through the slide seat 93 provided at the bottom, which cooperates with the slide groove 94 and the slide rail 92, and in this process, the height of the positioning seat 95 is lowered, so that the positioning seat 95 always moves synchronously with the support seat 63, and then the copper branch pipe 8 is placed on the positioning seat 95, and then the reciprocating cylinder 2 is started, and its operation drives the pressure seat 3 to move, and the copper branch pipe 8 is pushed toward the steel pipe 7 to complete the docking.
