Detailed implementation mode

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0028] As Figures 1 to 5 shown, a rotary support device for automatic welding of square pipes on a lifting wall includes a support base 1, a support bottom plate 2 fixedly connected to the bottom end of the support base 1, a conversion mechanism 31 fixedly connected to the top end of the support base 1, a fixing mechanism 32 provided on the conversion mechanism 31. The conversion mechanism 31 includes a support frame 311 fixedly connected to the top end of the support base 1. A groove is provided on the inner wall of the support frame 311, and a rotating groove 312 is provided on the inner wall of the groove. A support rotating plate 313 is slidably connected to the inner wall of the rotating groove 312. A ball 314 is movably connected to the outer wall of the support rotating plate 313. The outer wall of the ball 314 is in rolling contact with the inner wall of the rotating groove 312. A connecting plate 315 is fixedly connected to the outer wall of the support rotating plate 313 on the side opposite to the ball 314. A toothed ring 316 is fixedly connected to one end of the connecting plate 315 away from the support rotating plate 313. The toothed ring 316 meshes with a gear 317. A motor 318 is fixedly connected to the outer wall of the gear 317. A fixing plate 319 is fixedly connected to one end of the motor 318 away from the gear 317. The outer wall of the fixing plate 319 is fixedly connected to the top end of the support base 1.

[0029] Furthermore, the number of the support rotating plates 313 is eight. The support rotating plates 313 are evenly and equidistantly distributed in pairs at the four corners of the outer wall of the toothed ring 316. In this way, the toothed ring 316 can be synchronously supported in the up, down, left and right directions, thereby further improving the rotation stability of the toothed ring 316.

[0030] Furthermore, the outer wall of the support rotating plate 313 is fitted with the inner wall of the rotating groove 312, so as to ensure the tight fit between the outer wall of the support rotating plate 313 and the inner wall of the rotating groove 312, thereby improving the smoothness of the support rotating plate 313 during rotation.

[0031] Even further, a communication groove is provided on the outer wall of the support frame 311. The gear 317 is meshed and connected with the toothed ring 316 through the communication groove. In this way, the gear 317 can pass through the outer wall of the support frame 311 and be meshed and connected with the toothed ring 316 inside.

[0032] The fixing mechanism 32 includes a support fixing plate 321 fixedly connected to the inner wall of the gear ring 316. A through groove is formed on the outer wall of the support fixing plate 321. A communicating sliding hole is formed on the inner wall of the through groove. A sliding rod 322 is slidably connected to the inner wall of the communicating sliding hole. One end of the sliding rod 322 is fixedly connected with a limiting clamping plate 323. A connecting block 324 is fixedly connected to the outer wall of the sliding rod 322. A sliding hole is formed on the outer wall of the connecting block 324. A spring 325 is fixedly connected to the inner wall of the sliding hole. One end of the spring 325 away from the inner wall of the sliding hole is fixedly connected with a positioning rod 326. A round hole is formed at one end of the connecting block 324 opposite to the positioning rod 326. A pull rod 327 is slidably connected to the inner wall of the round hole. One end of the pull rod 327 is fixedly connected to the outer wall of one end of the positioning rod 326. The other end of the pull rod 327 away from the positioning rod 326 is slidably connected with a sliding sleeve 328.

[0033] Furthermore, the number of the limiting clamping plates 323 is two. The limiting clamping plates 323 are symmetrically distributed left and right in the through groove formed on the outer wall of the support fixing plate 321. In this way, the left and right outer walls of the square pipe can be tightly attached and clamped for limiting, so as to ensure the stability of the square pipe during limiting and fixing.

[0034] Even further, a positioning hole is formed on the outer wall of the support fixing plate 321. The positioning rod 326 is clamped in the inner wall of the positioning hole. The outer wall of the positioning rod 326 is fitted with the inner wall of the positioning hole. The positioning rod 326 can be clamped and limited through the positioning hole. At the same time, being fitted with the inner wall of the positioning hole can ensure the stability after clamping and limiting.

[0035] The implementation principle of a square pipe slewing bearing device for automatic welding of a lifting wall in this embodiment is as follows: After the square pipe is fixed, when the square pipe needs to be rotated and adjusted, the motor 318 can be started. Its output end will drive the gear 317 to rotate. When the gear 317 rotates, it can drive the gear ring 316 meshed with it to rotate. During the rotation of the gear ring 316, the connecting plate 315 and the support rotating plate 313 will be driven to rotate. At this time, the support rotating plate 313 will rotate along the inner wall of the rotating groove 312. At the same time, through the rolling action between the ball 314 and the inner wall of the rotating groove 312, the friction generated during the rotation of the support rotating plate 313 can be reduced, so that the gear ring 316 can drive the square pipe to rotate and adjust more smoothly. In this way, it is not necessary for the staff to frequently rotate the turning handle to drive the square pipe to rotate, thereby simplifying the operation process and facilitating the staff to process the square pipe more conveniently.

[0036] When fixing the square pipe, first pull the pull rod 327 to the left and right. At this time, the pull rod 327 will move inside the inner wall of the sliding sleeve 328, thereby driving the connecting block 324 and the sliding rod 322 to move. During the movement of the sliding rod 322, the limit clamping plate 323 can be driven to move in the left and right directions and move away from each other. Subsequently, place the square pipe between the limit clamping plates 323, and then push the connecting blocks 324 on both sides to drive the limit clamping plates 323 to move towards the middle. While clamping the outer wall of the square pipe, the connecting block 324 will drive the positioning rod 326 to move to the positioning hole. Subsequently, the spring 325 rebounds and resets to push the positioning rod 326 to insert into it, so as to limit the two limit clamping plates 323 and complete the fixing of the square pipe at the same time.
