When the second support plate 612 is in a horizontal state, the right-angled trapezoidal abutment block 214 in the second central clamping component 31 is completely retracted into the rectangular through hole 6111 away from the side of the fixed plate 212. When the second support plate 612 is in a vertical state, the right-angled trapezoidal abutment block 214 in the second central clamping component 31 is away from the side of the fixed plate 212 and passes through the rectangular through hole 6111 and catches the plate-like workpiece 7 in the turning process. After the front side of the plate-like workpiece 7 is processed, when the back side needs to be processed, the driving mechanism 4 drives the first support plate 611 and the second support plate 612 to rotate around their respective mounting seats 61, until the first support plate 611 and the second support plate 612 are both rotated to a vertical state.

The side away from the fixed plate 212 gradually shrinks into the rectangular through hole 6111 (on the first supporting plate 611), and at the same time, the horizontal section of the L-shaped connecting rod 216 in the second central clamping assembly 31 gradually moves to the top of the inner arc through hole 141 on the other side, the first spring 215 in the second central clamping assembly 31 gradually extends, and the right-angled trapezoidal abutting block 214 in the second central clamping assembly 31 gradually extends from the rectangular through hole 6111 (on the second supporting plate 612) on the side away from the fixed plate 212, thereby supporting the bottom of the plate-like workpiece 7 flipped to a vertical state.

[0025] A mounting through hole 6121 is provided at a position of the second support plate 612 away from the mounting seat 61. The adsorption assembly 32 is used to suck the side of the turned-over plate-like workpiece 7 away from the horizontal plate 6 to enhance the stability of the plate-like workpiece 7. The adsorption assembly 32 includes a second mounting plate 321 fixed in the mounting through hole 6121 and a suction cup 322 fixed on the second mounting plate 321. The suction cup 322 adsorbs the plate-like workpiece 7 after the second support plate 612 is adjusted to a vertical state. The air supply pipe of the suction cup 322 passes through the second mounting plate 321 and is connected to an external air source. When the right-angled trapezoidal abutment block 214 in the second center clamping assembly 31 gradually extends out from the rectangular through hole 6111 (on the second support plate 612) on the side away from the fixed plate 212 and supports the bottom of the plate-like workpiece 7 flipped to a vertical state, the control center of the five-axis machining equipment controls the external air source so that the air pressure at the suction cup 322 is negative pressure and sucks the flipped plate-like workpiece 7, thereby enhancing the stability of the flipped workpiece in the subsequent process of transforming into a horizontal state.

[0026] The second lateral clamping assembly 33 includes a second lateral clamping member 331 and a second guide rail 332. The structure and arrangement of the second lateral clamping member 331 are exactly the same as those of the first lateral clamping member 231. The diameter of the outer arc-shaped through hole 143 for slidingly engaging the lateral movable rod 2311 in the second lateral clamping member 331 is smaller than the diameter of the outer arc-shaped through hole 143 for slidingly engaging the lateral movable rod 2311 in the first lateral clamping member 231.

[0027] The second guide rail 332 is located on the side of the vertical plate 14 away from the horizontal plate 6. The second guide rail 332 on each vertical plate 14 is provided with two and symmetrically distributed on both sides of the outer arc-shaped through hole 143 corresponding to the second lateral clamping member 331. Each second guide rail 332 includes an L-shaped rod body 3321 fixed on the vertical plate 14, an arc-shaped overhead rod 3322 fixed to one end of the L-shaped rod body 3321 away from the vertical plate 14, and an arc-shaped guiding rod 3323 movably connected to one end of the arc-shaped overhead rod 3322 close to the processing platform 1 (the extension directions of the arc-shaped guiding rod 3323 and the arc-shaped overhead rod 3322 are both arc-shaped, and the axis of the arc-shaped guiding rod 3323 and the axis of the arc-shaped overhead rod 3322 are both coincident with the axis of the hinge shaft between the second support plate 612 and the mounting seat 61). The arc guide rod 3323 is connected to the arc overhead rod 3322 by an elastic connection assembly 8, and the end of the arc guide rod 3323 away from the arc overhead rod 3322 is kept in close contact with the side wall of the vertical plate 14 under the action of the elastic connection assembly 8. During the process of the second support plate 612 being adjusted to a vertical state, the arc guide rod 3323 allows the roller group 2318 in the second lateral clamping member 331 to move from the vertical plate 14 to the arc overhead rod 3322. After the plate-like workpiece 7 is flipped to a vertical state, the roller group 2318 in the second lateral clamping member 331 slides off the end of the arc overhead rod 3322 away from the arc guide rod 3323, and then presses against the side wall of the vertical plate 14 again, and rolls from between the arc overhead rod 3322 and the vertical plate 14 to the initial position.

[0028] The elastic connection assembly 8 includes a connecting seat 81 fixed to one end of the arc-shaped overhead rod 3322 close to the top of the processing platform 1, a connecting block 82 fixed to the end of the arc-shaped guide rod 3323 and hinged to the connecting seat 81, and a torsion spring 83 sleeved on the hinge shaft between the connecting seat 81 and the connecting block 82, and the two ends of the torsion spring 83 are respectively fixed to the connecting seat 81 and the connecting block 82.

[0029] The driving mechanism 4 is used to drive the first support plate 611 and the second support plate 612 to rotate around their respective mounting seats 61 to a vertical state and complete the turning operation of the plate-shaped workpiece 7. The driving mechanism 4 includes a first motor 41 fixed to the top of the processing platform 1, a first fixed block 42 fixed to the top of the processing platform 1, a bidirectional threaded rod 43 fixed to the output shaft end of the first motor 41 and rotatably connected to the first fixed block 42, a first movable plate 44 sleeved on the bidirectional threaded rod 43 and threadedly connected to the bidirectional threaded rod 43, a first special-shaped rod 45 hinged to the top of the first movable plate 44, a second movable plate 46 sleeved on the bidirectional threaded rod 43 and threadedly connected to the bidirectional threaded rod 43, and a second movable plate 47 sleeved on the bidirectional threaded rod 43 and threadedly connected to the second movable plate 48. The second special-shaped rod 47 is hinged on the top of the plate 46, and the bidirectional threaded rod 43 is provided with two sections of external threads with equal pitch, opposite rotation direction and symmetrically arranged about the cross plate 6 (the second movable plate 46 and the first movable plate 44 are symmetrically distributed on the two sections of external threads of the bidirectional threaded rod 43), the bottom surface of the first movable plate 44 and the bottom surface of the second movable plate 46 are both in contact with the upper surface of the bottom plate 12, the first special-shaped rod 45 is staggered with the first center clamping assembly 21, and the end of the first special-shaped rod 45 away from the first movable plate 44 is hinged to the bottom of the first support plate 611, the second special-shaped rod 47 is staggered with the second center clamping assembly 31, and the end of the second special-shaped rod 47 away from the second movable plate 46 is hinged to the bottom of the second support plate 612. When performing the flipping operation of the plate-shaped workpiece 7, the control center of the five-axis machining equipment controls the first motor 41 to work, thereby driving the bidirectional threaded rod 43 to rotate. Since the bottom surfaces of the first movable plate 44 and the second movable plate 46 are both in contact with the upper surface of the bottom plate 12, the first movable plate 44 and the second movable plate 46 are both threadedly connected to the bidirectional threaded rod 43, so that the first movable plate 44 and the second movable plate 46 are close to each other. The first support plate 611 is pushed by the first special-shaped rod 45 to rotate around the hinge axis between the first support plate 611 and one of the mounting seats 61, and the second support plate 612 is in the second special-shaped rod 45. Under the action of rod 47, the second support plate 612 is pushed to rotate around the hinge axis between the second support plate 612 and another mounting seat 61. During this process, under the joint action of the limit rod 2314 and the U-shaped sleeve 2315, the U-shaped clamping block 2313, the lateral connecting plate 2312, the lateral movable rod 2311, and the roller group 2318 in the first lateral clamping member 231 gradually move upward along the arc-shaped extension direction of the first guide rail 232, and the roller group 2318 in the second lateral clamping member 331 rolls along the arc-shaped guide rod 3323 to the arc-shaped overhead rod 3322 and continues to roll along the arc-shaped overhead rod 3322.When the first support plate 611 and the second support plate 612 are both in a vertical state, the roller group 2318 in the first lateral clamping member 231 moves to the position of the thickened portion 2321, and the roller group 2318 in the first lateral clamping member 231 pulls the lateral connecting plate 2312 horizontally through the lateral movable rod 2311, so that the U-shaped clamping block 2313 in the first lateral clamping member 231 is separated from the plate-like workpiece 7. At the same time, the roller group 2318 in the second lateral clamping member 331 slides off the end of the arc-shaped overhead rod 3322 away from the arc-shaped guide rod 3323, and the roller group 2318 in the second lateral clamping member 331 pushes the lateral connecting plate 2312 through the lateral movable rod 2311, so that the U-shaped clamping block 2313 in the second lateral clamping member 331 clamps the turned-over plate-like workpiece 7, further enhancing the stability of the turned-over plate-like workpiece 7 in the process of being placed in a horizontal state. Subsequently, the control center of the five-axis machining equipment controls the first motor 41 to work in the reverse direction, so that the first movable plate 44 and the second movable plate 46 are reset, and the turned-over plate-like workpiece 7 is gradually laid flat. During this process, the right-angled trapezoidal abutment block 214 in the second center clamping assembly 31 maintains the state of abutting the plate-like workpiece 7. When the horizontal section of the L-shaped connecting rod 216 in the second center clamping assembly 31 slides into the vertical connecting hole 142, the right-angled trapezoidal abutment block 214 in the second center clamping assembly 31 will be retracted into the rectangular through hole 6111, so that the control assembly 5 controls the turned-over plate-like workpiece 7 to return to the processing station. The limit rod 2314 and the U-shaped sliding sleeve 2315 are slidably matched to ensure the stability of the U-shaped clamping block 2313 during use, so that the U-shaped clamping block 2313 in the second lateral clamping member 331 can smoothly clamp the turned-over plate-like workpiece 7.

[0030] The control component 5 is arranged on the base plate 12, and is used for conveying the turned-over plate-shaped workpiece 7 back to the processing station. The control component 5 includes a second fixed block 51 fixed on the top of the base plate 12, and the second fixed blocks 51 are provided with four and are distributed in a rectangular array with respect to the base plate 12. The control component 5 also includes an active rod 52 rotatably installed between two second fixed blocks 51 on one side of the base plate 12, a driven rod 53 rotatably installed between two second fixed blocks 51 on the other side of the base plate 12, a driving pulley 54 fixedly sleeved on the active rod 52, a driven pulley 55 fixedly sleeved on the driven rod 53, a closed transmission belt 56 for connecting the active pulley 54 and the driven pulley 55, and a second motor 57 fixed on the second fixed block 51 and used for driving the active rod 52 to rotate. The active pulley 54, the driven pulley 55 and the closed transmission belt 56 are each provided with two groups and are symmetrically arranged, and the two closed transmission belts 56 are simultaneously located between the two first special-shaped rods 45 and the two second special-shaped rods 47. After the plate-like workpiece 7 is turned over, the control center of the five-axis machining equipment controls the external air source and causes the suction cup 322 to release the plate-like workpiece 7. The second motor 57 works and drives the active rod 52 to rotate, so that the active pulley 54, the driven pulley 55, and the closed transmission belt 56 all rotate. Under the action of the closed transmission belt 56, the plate-like workpiece 7 moves toward the side close to the initial processing state. After the plate-like workpiece 7 acts on the inclined surface of the right-angled trapezoidal abutment block 214, the right-angled trapezoidal abutment block 214 is driven to re-turn. Retracted into the rectangular through hole 6111 until the side of the plate-like workpiece 7 away from the cross plate 6 abuts against the abutment plate 223, the right-angled trapezoidal abutment block 214 in the first center clamping assembly 21 is reset under the action of the first spring 215, and the side of the plate-like workpiece 7 close to the cross plate 6 is limited. At this time, the U-shaped clamping block 2313 in the first lateral clamping member 231 is reset and the turned-over plate-like workpiece 7 is re-clamped, so that the horizontal five-axis compound machining center can perform processing operations on the reverse side of the plate-like workpiece 7.
