[0026] Embodiment 2:
[0027] A positioning and installation device for a cylinder body and an inner frame of an oil tank, such as Figure 1 and Figure 2As shown, it includes a cylinder fixing mechanism and a positioning and installation mechanism for realizing the positioning and automatic installation of the inner frame. The cylinder fixing mechanism includes a frame 1 and a locking support seat 4, an auxiliary support seat 3 and a positioning seat 2 which are arranged on the top of the frame 1 from left to right, and a positioning and installation mechanism is arranged on one side of the positioning seat 2. The positioning seat 2 is fixed on the frame 1, and the locking support seat 4 and the auxiliary support seat 3 are respectively slidably arranged on the frame 1. The two ends of the cylinder are rotatably connected to the positioning seat 2 and the locking support seat 4 respectively. The top of the auxiliary support seat 3 fits with the side wall of the cylinder to fix the position of the cylinder by friction.
[0028] The positioning and installation mechanism includes a column 8, a drive motor 10, a cross arm 9 and a positioning plate 11. The column 8 is provided with a cross arm 9 for horizontal sliding. The drive motor 10 is used to drive the cross arm 9 to move horizontally and linearly. The cross arm 9 is provided with a positioning plate 11 near the end surface of the cylinder. The drive motor 10 has the functions of moving forward, stopping and moving backward. The positioning plate 11 is positioned and connected to the inner frame through a positioning pin 12.
[0029] Preferably, the working surface of the locking support seat 4 can be circular or conical, and the locking support seat 4 and the auxiliary support seat 3 are respectively mounted on the guide rail 5, and the guide rail 5 can slide in the direction parallel to the bottom surface of the frame 1. The positioning seat 2 and the locking support seat 4 are both equipped with bearings that can rotate around the axis corresponding to the cylinder. An infrared laser pen 6 is installed on the top of the locking support seat 4 near the positioning seat 2, and a locking mechanism 7 is provided at the bottom to achieve fastening with the frame 1. A circumferential marking line is provided at one end of the cylinder corresponding to the infrared laser pen 6.

At this time, the cylinder is rotatably connected with the positioning seat 2 and the locking support seat 4 through the bearing, and the infrared laser pen 6 is turned on while the cylinder is rotated. When the cylinder rotates until the circumferential marking line coincides with the light emitted by the infrared laser pen 6, the rotation of the cylinder is stopped, and the auxiliary support seat 3 is moved to the right so that it contacts the cylinder to generate friction, thereby preventing the cylinder from rotating in the circumferential direction. Then, the end face of the inner frame is fitted through the positioning plate 11, and the positioning pin 12 is inserted into the hole of the inner frame part to position its circumferential direction. The drive motor 10 is turned on to rotate forward, so that the cross arm 9 moves to the left on the column 8, thereby sending the inner frame parts into the cylinder. When the cross arm 9 moves to the marked position and stops, the drive motor 10 is turned on to rotate reversely, and the cross arm 9 is driven to move to the right. The friction force generated by the contact between the inner frame and the cylinder causes the inner frame to separate from the positioning plate 11, thereby realizing the positioning installation of the inner frame, and the cross arm 9 finally returns to the initial position.
