DETAILED DESCRIPTION

[0035] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.

[0036] The present utility model embodiment specifically provides a turning device for pipe end processing, please refer to Figure 1 , comprising a body 1 and a uniform force component 2;

[0037] Among them, a turning assembly 11 and a chuck 12 are installed on the machine body 1. The chuck 12 is used to clamp the pipe. The uniform force assembly 2 is installed on the chuck 12. When the chuck 12 fixes the pipe, the uniform force assembly 2 fits with the inner wall of the pipe to evenly apply the turning deformation force to the pipe, thereby reducing the deformation force on the pipe, thereby reducing the force deformation of the pipe during turning.

[0038] During implementation, the turning assembly 11 includes a first moving assembly 14, a second moving assembly 15 and a cutter 16. The first moving assembly 14 is installed on the body 1, and the bottom of the second moving assembly 15 is connected to the first moving assembly 14. The first moving assembly 14 and the second moving assembly 15 are respectively the existing Y-axis moving structure and the X-axis moving component. Since the technology is relatively mature, it will not be described in detail here. The cutter 16 is fixed on the second moving assembly 15, and the cutter 16 is driven to move forward and backward by the first moving assembly 14, and is driven to move left and right by the second moving assembly 15, so as to adjust the appropriate turning position and turn the pipe.

[0039] For details, please refer to Figure 2The uniform force component 2 includes a push-pull rod 21, a synchronous disk 22, a telescopic frame 23 and a contact component 24. The push-pull rod 21 is rotatably installed on the chuck 12. The synchronous disk 22 is threadedly connected to the outer side of the push-pull rod 21. The two ends of the telescopic frame 23 are rotatably connected to the synchronous disk 22 and the chuck 12 respectively, so that the movement of the synchronous disk 22 drives the telescopic frame 23 to expand and move outward. The contact component 24 is arranged on the telescopic frame 23. The telescopic frame 23 contacts the inner wall of the pipe through the contact component 24, so that when the pipe is subjected to turning force, the turning force is evenly transmitted to the inner wall of the pipe through the telescopic frame 23, thereby improving the anti-deformation force.

[0040] For further information, please refer to Figure 3 The push-pull rod 21 includes a screw rod 211 and a knob 212 . One end of the screw rod 211 is rotatably mounted on the chuck 12 , and the other end is fixedly connected to the knob 212 . The screw rod 211 can be quickly rotated by the knob 212 , so as to conveniently drive the screw rod 211 to apply force to the synchronous disk 22 .

[0041] A support plate 13 is fixedly mounted at the center of the chuck 12, and a sleeve 213 is provided at one end of the screw rod 211 close to the support plate 13. The outer side of the sleeve 213 is fixed to the support plate 13, and the inner side of the sleeve 213 is rotatably connected to the screw rod 211, so that the screw rod 211 can stably rotate on the sleeve 213.

[0042] It is worth mentioning that the chuck 12 clamps the pipe and drives the chuck 12 to rotate through the machine body 1 to drive the pipe to rotate and turn. The rotation direction of the pipe is consistent with the rotation direction required on the screw 211 when the synchronous disk 22 moves to the right. Therefore, when the contact component 24 is tightly fixed to the inner wall of the pipe, when the pipe rotates, it can also drive the screw 211 and the synchronous disk 22 to rotate together to meet the needs of use. When turning is completed, the handle 212 can be rotated in the opposite direction to make the synchronous disk 22 drive the telescopic frame 23 to retract, so that the contact component 24 and the pipe are no longer in contact.

[0043] During implementation, the synchronization disk 22 includes a moving disk 221 and an installation port 222. The center of the moving disk 221 is threadedly connected to the screw rod 211. The installation port 222 is opened on the outside of the moving disk 221. The moving disk 221 is connected to the telescopic frame 23 through the installation port 222, so that when the screw rod 211 rotates forward or reversely, it can drive the moving disk 221 to move left or right to meet the use needs of the telescopic frame 23.

[0044] Among them, the number of installation openings 222 is set at two or more, and the installation openings 222 are arranged equidistantly along the circumference of the shift plate 221, and the number of telescopic frames 23 is consistent with the installation openings 222, so that the outer sides of all telescopic frames 23 can maintain the same center of the circle, and the screw rod 211 is concentric with the synchronous disk 22 and the chuck 12, and thus concentric with the pipe, so that the outer side of the telescopic frame 23 can be concentric with the pipe.

[0045] Furthermore, the telescopic frame 23 includes a bracket 231 and a support frame 232 which are rotatably connected to each other. The outer ends of the bracket 231 and the support frame 232 are rotatably connected to the installation port 222 and the support plate 13 respectively, so that when the moving plate 221 moves to the right, the bracket 231 pushes the support frame 232, so that after the support frame 232 rotates, its outer side is in synchronous contact with the inner wall of the pipe, thereby stabilizing the pipe while being able to evenly transmit and bear force on the inner wall of the pipe.

[0046] Among them, a base 233 is fixedly installed at the inner end of the support frame 232, and the inner wall of the base 233 is rotatably connected to the bracket 231. The outer end of the support frame 232 is rotatably installed on the swivel seat 234, and the end of the swivel seat 234 away from the support frame 232 is rotatably connected to the support plate 13, so that the support frame 232 can be stably and quickly rotated with the bracket 231 and the support plate 13, thereby improving the convenience and stability of use.

[0047] Please refer to Figure 4 The contact component 24 includes a plate 341, a rotating plate 242 and a gasket 243. The bottom end of the plate 341 is fixed to the rotating plate 242. The inner wall of the rotating plate 242 is rotatably connected to the support frame 232. The gasket 243 is fixed to the upper surface of the plate 341, so that when the support frame 232 expands outside the inner wall of the tube, the plate 341 can be tightly attached to the inner wall of the tube to increase the contact area and facilitate force transmission.

[0048] The material of the gasket 243 is rubber or silicone, so that the contact plate 341 can be stably attached to the inner wall of the pipe and the contact surface is protected from wear.

[0049] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
