[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-5 ,like Figure 1 As shown, an X-frame automatic flipping machine consists of two sets of main units 1 that work together, and a flipping machine tooling unit 2 installed on the main units 1 for flipping and limiting the workpiece.

[0030] like Figure 2 As shown, the main unit 1 consists of a positioner housing 11, a sliding mechanism for displacing the positioner housing 11, and a lifting mechanism installed on the positioner housing 11 for lifting and tilting tooling unit 2.

[0031] The sliding mechanism consists of an X-axis drive 13 as a power source, a ground rail slide 15 installed at the bottom of the positioner housing 11, and a movable ground rail 14 connected below the ground rail slide 15. The X-axis drive 13 is fixed to the ground rail slide 15, and drives the ground rail slide 15 to slide on the movable ground rail 14. A hydraulic station 17 is also installed on the ground rail slide 15.

[0032] The lifting mechanism consists of a drive slide 12 that is slidably mounted on the positioner housing 11 and a lifting drive 16 that drives the drive slide 12. The lifting drive 16 drives the drive slide 12 to move up and down on the positioner housing 11.

[0033] like Figure 3 As shown, the tooling unit 2 of the flipping machine is equipped with a flipping disc 27 connected to the drive slide 12 for flipping the workpiece, a mounting frame 24 mounted on the flipping disc 27, a drive mechanism 21 mounted on the mounting frame 24, two sets of U-shaped clamping mechanisms 22 with symmetrical upper and lower shapes mounted on the drive mechanism 21, and a positioning mechanism 25 for positioning the workpiece on the mounting frame 24; the workpiece is clamped by the positioning mechanism 25, and the drive mechanism 21 drives the two sets of clamping mechanisms 22 to move in opposite directions to clamp and limit the workpiece.

[0034] The clamping mechanism 22 has pressure heads 23 at both ends of the contact surface with the workpiece, and an in-situ sensor 26 for monitoring the workpiece is installed on the clamping mechanism 22 near the pressure head 23.

[0035] like Figure 4 As shown, the drive mechanism 21 consists of two symmetrically arranged sliding plates 211 and a base 212 slidably connected below the two sets of sliding plates 211. Each set of sliding plates 211 is fixed with a clamping mechanism 22 and threadedly connected to a T-shaped lead screw 213. One end of the T-shaped lead screw 213 is connected to a hydraulic motor 214, which is connected to the hydraulic station 17. An encoder 215 is installed at the other end of the T-shaped lead screw 213. The hydraulic motor 214 drives the T-shaped lead screw 213 to rotate. The T-shaped lead screw 213 is threadedly connected to the two sets of sliding plates 211, causing the two symmetrically arranged sliding plates 211 to move opposite each other on the base 212. Bellows covers 216 are also installed on both sides of the sliding plates 211.

[0036] like Figure 5 As shown, two sets of positioning mechanisms 25 are symmetrically arranged between two sets of clamping mechanisms 22. The positioning mechanism 25 is provided with a mounting base 251 connected to the mounting frame 24. A floating positioning head 252 is installed at the end of the mounting base 251. The floating positioning head 252 is hinged to the mounting base 251 through a pin 253. The mounting base 251 is provided with a fixed shaft 254. A tension spring 255 is connected to the fixed shaft 254. One side of the floating positioning head 252 is connected to the other end of the tension spring 255 to form an elastic structure.

[0037] In this embodiment, the X-axis drive 13 and / or the lifting drive 16 can be driven by a motor or electric motor to drive the pulley, so that the drive slide 12 moves on the positioner housing 11 and / or the ground rail slide 15 moves on the moving ground rail 14. Similarly, the drive method for the tilting plate 27 can also be driven by a motor or electric motor, but it is not limited to the above means. It can also be driven by screw thread connection, gear rack and pinion, etc. Those skilled in the art can select and set conventional technical means according to the actual working conditions, which will not be described in detail here.

[0038] In practice, the two sets of main units 1 are symmetrically arranged and returned to their initial positions. Then, the RGV trolley transports the workpiece to the preset loading and unloading position. According to different workpieces, the lifting drive 16 drives the drive slide 12 to move up and down on the positioner housing 11. The height of the drive slide 12 is adjusted to the middle of the workpiece. Then, the X-axis drive 13 is started to drive the main unit 1 on the ground slide 15 to slide on the moving ground rail 14. The two sets of main units 1 move inwards towards each other. At this time, the floating positioning heads 252 on the four positioning mechanisms 25 on the two sets of main units 1 come into contact with and clamp the workpiece. Since the floating positioning head 252 is hinged, it can adapt to different angles to be suitable for different types of workpiece plates. The tension spring 255 connected to the floating positioning head 252 is stretched and resets through elastic potential energy after the positioning is released.

[0039] After positioning is completed, the hydraulic motor 214 of the drive mechanism 21 is started to drive the T-shaped lead screw 213 to rotate. The T-shaped lead screw 213 is threadedly connected to the slide plate 211, so that the two sets of slide plates 211 are displaced in opposite directions on the base 212, so that the two sets of clamping mechanisms 22 on the two sets of slide plates 211 clamp the workpiece until the in-place sensor 26 senses that the workpiece stops moving. Finally, after adjusting the height of the turning machine tooling unit 2, the turning plate 27 is started to turn to the specified angle and then the turning machine tooling unit 2 is dropped to release the clamping and is transferred by the RGV trolley.

[0040] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
