[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 A large thin-walled curved pipe path fitting device includes a fixed seat 3, a platform tilting mechanism 1 and a pipe clamping mechanism 2. The fixed seat 3 serves as the basic supporting structure of the entire device, ensuring that the device is stably and firmly placed in the working environment, and providing stable support for the platform tilting mechanism 1 and the pipe clamping mechanism 2.

[0021] See also Figure 2-4 The platform tilting mechanism 1 is fixedly mounted on the fixing seat 3, and the pipe clamping mechanism 2 is arranged on the top of the platform tilting mechanism 1. The platform tilting mechanism 1 is used to adjust the angle between the pipe clamping mechanism 2 and the horizontal plane. By adjusting the angle between the pipe clamping mechanism 2 and the horizontal plane, the platform tilting mechanism 1 enables the pipe clamping mechanism 2 to adapt to the bending requirements of pipes at different angles, thereby better adapting to the bending path of the pipe. The pipe clamping mechanism 2 is used to clamp and support the pipe. The pipe clamping mechanism 2 can firmly clamp the pipe to prevent it from moving or deforming, thereby improving the accuracy of detection.

[0022] The platform tilting mechanism 1 includes a left base 103 and a right base 110, which are fixedly mounted on the fixed base 3 in parallel, and the left base 103 and the right base 110 are mounting bases of the platform tilting mechanism 1. A rotation auxiliary base 1031 and a mounting base 1 1033 are disposed on the left base 103 and the right base 110, and a rotation axis 2 1032 is disposed on the rotation auxiliary base 1031. The rotation auxiliary base 1031 and the rotation axis 2 1032 thereon serve as the rotation axis of the fixed slide rail 111, so that the fixed slide rail 111 performs a circular motion around the rotation axis 2 1032 when being lifted.

[0023] The left base 103 and the right base 110 have the same main body shape, but the left base 103 is also provided with a mounting seat 2 1034, a mounting seat 3 1035 and a mounting seat 4 1036, a servo motor 3 104 is mounted on the mounting seat 3 1035, a worm 108 is mounted between the mounting seat 2 1034 and the mounting seat 4 1036, a bearing 106 is also mounted on the mounting seat 4 1036, a retaining ring 107 is mounted on the worm 108, and the worm 108 and the servo motor 3 104 are connected via a plum blossom coupling 105. The above is the prior art and will not be described in detail here.

[0024] Bearing No. 2 112 is provided on the mounting seat No. 1 1033 of the left base 103 and the right base 110, and a tilting rotating shaft 102 is assembled between the bearing No. 2 112. A turbine 109 is provided at one end of the tilting rotating shaft 102, and the turbine 109 is meshed with the worm 108. When the servo motor No. 3 104 drives the tilting rotating shaft 102 to rotate, the tilting rotating shaft 102 can drive the moving component 113 to rotate around the tilting rotating shaft 102, thereby lifting one end of the fixed slide rail 111 to achieve the tilting of the tilting platform 101.

[0025] The tilting rotation axis 102 is located at both ends of the left base 103 and the right base 110, and the moving assembly 113 is fixedly installed. The moving assembly 113 includes a rotating rod 1133, one end of the rotating rod 1133 is provided with a mounting hole 5 1134, and the tilting rotation axis 102 is fixedly installed in the mounting hole 5 1134. The other end of the rotating rod 1133 is rotatably provided with a rotating shaft 3 1131, and both ends of the rotating shaft 3 1131 are provided with a moving auxiliary ball 1132. When the tilting rotation axis 102 drives the rotating rod 1133 to rotate, the moving auxiliary ball 1132 at one end of the rotating rod 1133 will move in an arc upward and outward, thereby lifting the end of the fixed slide rail 111 away from the rotating seat 1111 upward, thereby realizing the tilting of the tilting platform 101.

[0026] The left base 103 and the right base 110 are both provided with a fixed rail 111 on the second rotation axis 1032. A rotating seat 1111 is provided at one end of the fixed rail 111. The rotating seat 1111 is rotatably mounted on the second rotation axis 1032. The second rotation axis 1032 serves as the rotation axis of the fixed rail 111. Two limiting rails 1112 are provided at the bottom of the fixed rail 111. The moving auxiliary ball 1132 of the moving assembly 113 is located in the limiting rail 1112. During the rotation process, the moving auxiliary ball 1132 is limited in the limiting rail 1112. During the rotation process, the moving auxiliary ball 1132 will drive one end of the fixed rail 111 to lift upward, thereby driving the tilting platform 101 above the fixed rail 111 to tilt.

[0027] See also Figure 5-7The pipe clamping mechanism 2 includes a limit block 203 and a movable clamping block 209. The limit blocks 203 are two and are fixedly installed in parallel on the inclined platform 101. A linear slide rail 204 is arranged on the limit block 203. The limit block 203 is used to install the linear slide rail 204 and fix the linear slide rail 204 on the inclined platform 101.

[0028] Two movable clamping blocks 209 are arranged opposite to each other between the two linear guide rails 204, and the linear guide rails 204 are also used to provide a limit for the movement of the movable supporting block. The movable clamping block 209 is provided with a ball screw nut 210, and a bidirectional screw 202 is passed through the ball screw nut 210. Since two movable clamping blocks 209 are provided, and the two movable clamping blocks 209 need to realize the clamping action, the two clamping blocks move toward each other or away from each other during movement, so the rotation of the bidirectional screw 202 can realize this movement mode between the two clamping blocks. In addition, the arc-shaped notch 2091 provided on the movable clamping block 209 enables the movable clamping block 209 to have two ways of clamping the pipe fittings, one of which is that the two movable clamping blocks 209 are parallel to the pipe fittings and clamp them from the side of the pipe fittings; the other is that the two movable clamping blocks 209 are perpendicular to the pipe fittings, and the pipe fittings are directly placed on the notches 2091 of the two movable clamping blocks 209.

[0029] The two ends of the bidirectional screw rod 202 are respectively provided with a rear bearing seat 201 and a front bearing seat 205, which are fixedly mounted on the tilting platform 101. A servo motor mounting seat 206 is also fixedly mounted on the tilting platform 101. A servo motor four 207 is mounted on the servo motor mounting seat 206. The servo motor four 207 and the bidirectional screw rod 202 are connected via a plum blossom coupling two 208. The above is the prior art and will not be elaborated here.

[0030] Working principle: When clamping and supporting pipes, the device requires multiple devices to cooperate with each other. The pipes are clamped or supported on the pipe clamping mechanism 2 of each device, and then the platform tilting mechanism 1 and the pipe clamping mechanism 2 are used to regulate and clamp the pipes along the curved path of the pipes, so as to better fit the pipes and fix them.

[0031] First, the platform tilting mechanism 1 is tilted. The servo motor 3 104 drives the worm 108 to rotate, and the worm 108 drives the turbine 109 to rotate, which further drives the tilting rotation shaft 102 to rotate. The rotation of the tilting rotation shaft 102 drives one end of the moving component 113 fixed thereon to rotate, and the moving auxiliary ball 1132 of the moving component 113 rotates around the tilting rotation shaft 102 while sliding outward in the track formed by the limiting track 1112, so that the fixed slide rail 111 rotates upward around the rotating seat 1111, and finally the tilting platform 101 is at a certain angle to the horizontal plane.

[0032] Next is the pipe clamping mechanism 2. The bidirectional screw rod 202 is driven to rotate by the servo motor 207, so that the two moving clamping blocks 209 on the linear slide rail 204 move toward each other to complete the clamping of the pipe.
