[0044] See Figures 1 - 20, this embodiment provides a BOSA automatic assembly and welding machine, including a frame 1. A square seat discharging device 4, a press-fitting device 6, a pipe fitting feeding device 5, a welding device 7, a discharging device 8, and a picking and feeding device 9 are arranged on the top of the frame 1. The press-fitting device 6 includes a pressing mechanism 61 and a rotary conveying mechanism 60. A pipe fitting feeding station, a press-fitting station, a discharging station, and a square seat feeding station are respectively arranged in the front, rear, left, and right of the rotary conveying mechanism 60.

[0045] The rotary conveying mechanism 60 includes a four-station divider 605 installed at the bottom of the top surface of the frame 1. The input end of the four-station divider 605 is connected with a conveying mechanism driven wheel 603, and a rotary motor mounting plate 601 is fixed on one side of its input end. A rotary driving motor 600 is installed on the rotary motor mounting plate 601. The output shaft of the rotary driving motor 600 is connected with a conveying mechanism driving wheel 602.

The output end of the four-station divider 605 is connected with a turntable 606 located above the top surface of the frame 1. When the rotary driving motor 600 is started and the output shaft of the rotary driving motor 600 rotates, the conveying mechanism driving wheel 602 will also rotate accordingly. The rotation of the conveying mechanism driving wheel 602 will drive the conveying mechanism conveyor belt 604 to move, and the movement of the conveying mechanism conveyor belt 604 will drive the conveying mechanism driven wheel 603 to rotate. The rotation of the conveying mechanism driven wheel 603 will drive the input shaft of the four-station divider 605 to rotate. When the input shaft rotates, the four-station divider 605 converts the input continuous rotational motion into an intermittent rotational motion, so that the turntable 606 rotates 90° each time. So as to facilitate corresponding operations, such as TO pipe fitting feeding, square seat feeding, press-fitting of TO pipe fitting and square seat, finished product discharging, etc.

[0046] Four evenly distributed press-fitting material positioning seats 607 are provided on the top of the turntable 606.

The spring 6073 is located between the convex ring 60710 and the bushing 6072, and the TO clamping seat 6074 can float under the action of the spring 6073. The TO clamping seat 6074 and the top end of the positioning seat 6071 penetrate through the fixture limit flange 6070, and the bottom end of the TO clamping seat 6074 is clamped on the top bottom surface of the fixture limit flange 6070 under the action of the spring 6073. An opening is provided at the top of the TO clamping seat 6074, and a square seat placement table 60740 is provided on the inner edge of the opening. The top end of the TO positioning seat 6071 is located at the opening, and a concave platform 60711 is provided on the top of the TO positioning seat 6071. There is a movable gap between the top surface of the concave platform 60711 and the top bottom surface of the TO clamping seat 84. The movable gap between the top surface of the concave platform 60711 and the top bottom surface of the TO clamping seat 84 is a floating space. The TO positioning seat 6071 is provided with a positioning hole 6079 and an air passage 6078 from top to bottom, and the two are connected. The bottom of the TO positioning seat 6071 passes through the turntable 606 downward and is connected to a first rotary joint 6077; four quick connectors 6080 connected to an external vacuum source are connected to the outer surface of the swivel joint 608, and four second rotary joints 6081 are provided at the bottom of the swivel joint 608.

A pressing movable plate 612 is fixed to the outer side walls of the two pressing slide seats 614. A through hole 6120 is formed in the pressing movable plate 612. The pressing screw block 615 extends outward and passes through the through hole 6120, and a pressing frustum 616 is arranged at the bottom of its outer end. When the pressing drive motor 617 works, it drives the pressing screw block 615 to move downward, and the pressing movable plate 612 moves downward accordingly. The through hole 6120 limits the pressing screw block 615 during its movement. As the pressing screw block 615 moves downward, the pressing frustum presses the TO pipe fitting and the square seat placed on the press-fitting material positioning seat 607 located at the press-fitting station on the turntable 606 together. During the pressing process, the square seat 18 is located on the square seat placement table 60740 of the TO clamping seat 84, and the TO pipe fitting 22 is located on the top of the TO positioning seat 6071. Since there may be dimensional errors and position deviations in the processing and assembly of the TO pipe fitting 22 and the square seat 21, the floating TO clamping seat 6074 can automatically adjust its position according to the actual situation to ensure better alignment and cooperation between the square seat 21 and the TO pipe fitting 22 during the press-fitting process, and avoid assembly difficulties or damage caused by position deviations. In addition, during press-fitting, the TO clamping seat 6074 can move downward to buffer part of the pressure, preventing the pipe fitting or the square seat from deforming, cracking or damaging the surface due to excessive impact force, and protecting the integrity and performance of the parts.
