[0033] The support frame 8 and the hydraulic cylinder II 11 are fixed on the support frame 8.

[0034] This technical solution may also include the following technical details to better achieve the technical effect: it also includes a control system for controlling the power system.

[0035] This technical solution may also include the following technical details to better achieve the technical effect: the control system is a CNC hydraulic station 2, which can manage external communications and design the pressure of each cylinder solenoid valve; all hydraulic cylinder stroke actions of hydraulic cylinder I10 and hydraulic cylinder II11 are equipped with a wire-drawing displacement sensor, which is installed between hydraulic cylinder II11 and flip plate 12, and between hydraulic cylinder I10 and clamping block 9; the wire-drawing displacement sensor is connected to the CNC hydraulic station 2 for communication, and the wire-drawing displacement sensor sends a position signal to the CNC hydraulic station 2 after the hydraulic cylinder II11 and hydraulic cylinder I10 are extended to the specified position, and the CNC hydraulic station 2 controls the hydraulic cylinder to complete the extension and retraction action instruction. The control system manages the operating stroke position of the hydraulic cylinder, controls the extension and retraction of the lifting system hydraulic cylinder by detecting the individual pressure of each cylinder and the position of the displacement sensor, and completes the cylinder blank flipping action at any angle.

[0036] The technical solution may also include the following technical details to better achieve the technical effect: the hydraulic cylinder Ⅰ10 is composed of two hydraulic cylinders, which respectively control the movement of two clamping blocks 9, and the surface of the clamping block 9 in contact with the cylinder blank is a plane, completing the clamping action of the cylinder blank and fixing the position;

[0037] The hydraulic cylinder II 11 is composed of 4 hydraulic cylinders, 2 of which control a flip plate 12. The 2 hydraulic cylinders are symmetrically arranged to synchronously control the flip plate 12, so that the flip plate 12 is more stable during the flipping process, and the flipping of the flip plate 120-90° is controlled, thereby completing the operation goal of converting the cylinder blank from horizontal to vertical or from vertical to horizontal.

[0038] The present technical scheme may also include the following technical details to better achieve the technical effect: the support frame 8 is welded from steel plates, and the middle structural part of the support frame 8 is sunken to place the hydraulic cylinder Ⅱ11 in the flipping system to prevent the hydraulic cylinder Ⅱ11 from restricting the flipping of the flip plate 12; the control system (CNC hydraulic station 2) is installed under the middle cross beam of the support frame 8; the support frame 8 is fixed on the base system, and the flipping system is fixed on the support frame 8; the support frame 8 serves as the intermediate connecting support between the flipping system and the base system, and the overall lightweight design is adopted to reduce the bearing strength of the base system and improve the stability of the entire flipping mechanism.

Figure 7 As shown, the fixed baffle plate 6 is provided with a positioning screw hole 16, and a positioning bolt is installed on the positioning screw hole 16. The fixed baffle plate 6 limits the two flip plates 12 to prevent them from moving, thereby maintaining the stability of the cylinder blank flipping process.

[0042] An operation process of an automatic turning mechanism clamping a cylinder blank, such as Figure 8As shown, it should be noted that, except for the manual loading of the cylinder blank, the rest of the actions are automatically realized by the control system, which specifically includes the following steps:

[0043] Step 1: The two flip plates 12 are opened 180 degrees by the hydraulic cylinder II 11, and the cylinder blank is manually loaded onto one of the flip plates 12, and the clamping block 9 on that side is adjusted to fit with one side of the blank cylinder;

[0044] Step 2: The flip plate 12 on the other side is flipped 90 degrees by the hydraulic cylinder II 11, so that the flip plate 12 fits the cylinder blank, and the clamping block 9 on this side is adjusted to clamp the fixed side of the blank cylinder;

[0045] Step 3: Synchronously adjust the two hydraulic cylinders II 11 until the two flip plates 12 rotate counterclockwise to an angle of 90° with the horizontal plane, and the cylinder blank is in the flipping process.
