The lower ends of the surfaces of the two fixed platforms 1 close to each other are provided with horizontal clamps 8, and the upper ends of the surfaces of the two fixed platforms 1 close to each other are provided with vertical clamps 5. The single-claw clamp 103 of the limiting mechanism at the bending part of the seat 7 is replaced with a double-claw clamp 109. The horizontal clamp 8 provides horizontal support for the seat 7, and the vertical clamp 5 provides vertical limitation for the seat 7. The limiting mechanism cooperates with the vertical clamp 5 and the horizontal clamp 8 to fix the seat 7 on one side of the fixed platform 1, and then cooperates with the transportation mechanism to move the seat 7.

[0028] like Figure 3-Figure 4 As shown, the limiting mechanism includes a limiting cone 108 fixedly installed on the relative outer surfaces of the two fixed platforms 1, a pull rod 102 is installed through the limiting cone 108, a handle 101 is provided on the outer side of the pull rod 102 relative to the limiting cone 108, a spring 107 is provided on the outer surface of the pull rod 102 located between the limiting cone 108 and the fixed platform 1, and a single-claw clamp 103 is rotatably installed on the inner side of the pull rod 102 relative to the limiting cone 108. When the seat 7 needs to be limited and fixed, the part of the pull rod 102 located inside the limiting cone 108 is sleeved with a spring 107. The spring 107 makes the pull rod 102 continue to move upward, and the single-claw clamp 103 installed on one side of the pull rod 102 is rotated to fit the pipe support 106, thereby limiting the seat 7.

[0029] A pipe support 106 is provided between the single-jaw clamp 103 and the fixed platform 1, and a limit seat 104 is provided between the pipe support 106 and the pull rod 102. A connecting plate 105 is rotatably installed on the upper and lower ends of the limit seat 104.

The lower support plate 201 provided at the lower end of the transport frame 3 lifts the hanging plate 4 provided on one side of the fixed platform 1, and after the transport frame 3 is fixedly installed, the fixed platform 1 can be pushed to move its position.

[0031] Symmetrical rotating seats 206 are provided on both sides of the lower surface of the rear cross arm 204, and a support arm 208 is rotatably installed between each rotating seat 206. Universal wheels 202 are provided at the lower ends of the two support arms 208 and the lower end of the transport frame 3. Symmetrical rotating plates 207 are provided on the lower surface of the front cross arm 203. The relative inner surfaces of the two rotating plates 207 are provided with two connecting rods 209 rotatably installed with one side of the support arm 208.

[0033] A welding plate 305 is fixedly installed on one side surface of the driving bent plate 301, and a welding gun 306 is fixedly installed on the front surface of the welding plate 305. The welding plate 305 is adjusted in position by the rotating wheel 303 to control the driving bent plate 301 to move along the rotating wheel 303, thereby adjusting the angle of the welding gun 306 to perform rotational welding on the joint of the seat 7.

[0034] Working principle: The present invention is used for welding the seat 7 of the upper limb press trainer, and two symmetrical fixed platforms 1 are moved to the two sides of the seat 7 through the transportation mechanisms on both sides. The seat 7 has an S-shaped bent pipe structure with two bends. The middle sections of the relative inner surfaces of the two fixed platforms 1 are provided with horizontal clips 8 to provide horizontal support for the seat 7 while limiting the position. The two bends and the lower end of the seat 7 are respectively provided with limiting mechanisms. A pull rod 102 is arranged on the outside of the limiting cone 108 in the limiting mechanism, and the pull rod 102 passes through the limiting cone 108 and the fixed platform 1, and a spring 107 is sleeved on the part of the pull rod 102 located between the limiting cone 108 and the fixed platform 1. The elastic force of the spring 107 causes the pull rod 102 to be subjected to a continuous inward force, so that the single-claw clamp 103 rotatably installed on one side of the pull rod 102 continuously fits the pipe support 106 below, and a limiting seat 104 is arranged between the pipe support 106 and the pull rod 102, and connecting plates 105 are rotatably installed on the upper and lower surfaces of the limiting seat 104, and one side of the two connecting plates 105 is rotatably installed on the upper and lower surfaces of the single-claw clamp 103, and the single-claw clamp 103 is rotatably connected to the limiting seat 104 through the connecting plate 105. The single-claw clamp 103 in the limiting mechanism located at the bending part of the seat 7 is replaced with a double-claw clamp 109. The double-claw clamp 109 provides a larger support point for the bending part of the seat 7 to avoid shaking during the clamping process. The two limiting mechanisms cooperate with the horizontal clip 8 and the upright clip 5 installed on the relative inner surface of the fixed platform 1 to flexibly limit the seat 7, which is convenient for the staff to install and disassemble the seat 7.

[0035] A transport frame 3 is fixedly installed at the lower end of the outer surface of the fixed platform 1, a front cross arm 203 is arranged at the front end of the transport frame 3, lower support plates 201 are arranged on both sides of the lower end of the transport frame 3, the lower support plates 201 are clamped to the hanging plate 4 fixedly installed at the lower end of one side of the fixed platform 1, so that the transport frame 3 is fixedly installed on the surface of one side of the fixed platform 1, and columns 205 are respectively arranged between the two lower support plates 201 and the transport frame 3, and a rear cross arm 204 is arranged between the two columns 205. A symmetrical rotating seat 206 is arranged at the lower end of the rear cross arm 204, and a support arm 208 is rotatably installed at the lower end of each rotating seat 206. The lower surface of the front cross arm 203 is provided with Two symmetrical rotating plates 207 are installed with two connecting rods 209 connected by locking screws 210 on their relative inner surfaces. The bending of the support arm 208 can be adjusted by adjusting the tightness of the locking screws 210. Since the device can fix and weld the seat 7 after displacement, the seat 7 needs to be moved to the top of a special fixing frame for welding. During the stage of limiting and fixing the seat 7, the support arm 208 maintains a vertical state to provide support for the transport frame 3 to avoid overturning caused by the uneven center of gravity of a single fixed platform 1. When the seat 7 needs to be displaced, the support arm 208 can be bent along the rotating seat 206 by adjusting the locking screws 210.

[0036] There are four welding points between the seat 7 and the fixed frame. The equipment is provided with corresponding seam welding mechanisms at the upper and lower ends of the fixed platform 1. A driving bent plate 301 is provided at the front end of the mounting frame 6. The welding plate 305 is moved along a fixed track by rotating the rotating wheel 303 installed at the front end of the mounting frame 6, so as to weld the seam of the seat 7 at the upper end. The welding of the seat 7 at the lower end is performed by rotation welding by the horizontal moving frame 9 at the lower end of the fixed platform 1, wherein a cam 304 is provided at the middle end of the rotating wheel 303, and a corresponding limiting groove 302 is provided on the inner wall of the driving bent plate 301 to prevent the driving bent plate 301 from falling off while performing limiting movement, thereby maintaining the stability of the welding.
