[0002] The turnover device for automobile part processing is usually called a turnover workbench, a turnover device or a turnover fixture. This device is mainly used to turn or rotate workpieces so as to complete operations at different angles during the processing, and is usually used for processing parts with complex shapes, especially automobile parts. The turnover device can usually precisely control the turnover of parts to ensure the accuracy and efficiency of processing.

[0037] A method for using a flipping device for automobile part processing, comprising the following steps:

[0038] Step 1: Flip the workpiece. Place the workpiece above the middle conveyor belt, start the first motor. The first motor drives the first rotating shaft to rotate, the first rotating shaft drives the first roller to rotate, the first roller drives the conveyor belt to rotate, the conveyor belt drives the workpiece to be transported. The workpiece moves between the two flipping plates. Then turn off the first motor and start the second motor. The second motor drives the second rotating shaft to rotate, the second rotating shaft drives the connecting plate to rotate, the connecting plate drives the flipping plate to rotate, and the flipping plate drives the workpiece to be flipped;

[0039] Step 2: Position the workpiece. When the surface of the workpiece to be pressed is uneven, due to the reaction force of the workpiece, the rotating ball drives the second sliding frame to move upward. Due to the setting of the limiting shell, the second sliding frame will move upward along the inner wall of the limiting shell, so as to stably press different uneven surfaces of the workpiece. When the top of one of the second sliding frames moves to the top of the inner wall of the limiting shell, the limiting shell will move upward, the limiting shell drives the first rotating bar to move upward, the first rotating bar drives the first slider to move upward. Limited by the sliding hole, the first slider slides along the inner wall of the sliding hole. The first slider drives the special-shaped plate to move, the two special-shaped plates move closer to each other, the special-shaped plate drives the square shell to move, the square shell drives the square plate to move, the square plate drives the clamping frame to move. During the process of the two clamping frames moving towards each other, the two sides of the workpiece can be clamped;

[0040] Step 3: Improve the flipping stability of the workpiece. When affected by the reaction force of the workpiece, the clamping frame drives the square plate to move into the square shell. The square plate drives the second rotating bar to move. Limited by the square shell, the second rotating bar drives the second slider to move along the inner wall of the square shell. The second slider drives the extrusion plate frame to move. During the movement of the extrusion plate frame, it will contact the square bladder, so that the air flow inside the square bladder enters the inside of the one-way flow tube. The air flow enters the inside of the fixed shell through the one-way flow tube. The air flow makes the first sliding frame inside the fixed shell slide. The first sliding frame drives the flexible plate to move. The two separated flexible plates move closer to each other, so as to clamp the workpiece.

[0041] The present invention has the following beneficial effects:

[0042] (1) In the present invention, the workpiece is placed above the conveyor belt in the middle. The first motor is started, and the first motor drives the first rotating shaft to rotate. The first rotating shaft drives the first roller to rotate, and the first roller drives the conveyor belt to rotate. The conveyor belt drives the workpiece to be transported. When the workpiece moves between the two flipping plates, the first motor is turned off, and the second motor is started. The second motor drives the second rotating shaft to rotate, the second rotating shaft drives the connecting plate to rotate, the connecting plate drives the flipping plate to rotate, and the flipping plate drives the workpiece to perform the flipping operation. When the connecting plate rotates a quarter of a circle, the workpiece moves upward. The second motor is turned off, and the first motor is started. The first motor drives the next workpiece above the conveyor belt to be transported. At the same time, the first rotating shaft drives the belt to rotate, the belt drives the cross bar to rotate, and the cross bar drives the reciprocating screw rods with opposite threads to rotate. Due to the arrangement of the concave frame housing, the reciprocating screw rods drive the threaded blocks to move horizontally. At this time, during the process of the workpiece moving between the two flipping plates, the threaded blocks will perform a reciprocating motion for one cycle on the outer wall of the reciprocating screw rods. When the two threaded blocks move closer to each other, the threaded blocks drive the rotating plate to move, the rotating plate drives the lower pressing plate to move vertically downward, the lower pressing plate drives the second sliding frame to descend, and the second sliding frame drives the rotating ball to descend, so that the rotating ball presses the workpiece, thereby enabling the workpiece to be firmly stuck between the two flipping plates, improving the stability of the workpiece flipping.

[0043] (2) In the present invention, when the pressed surface of the workpiece is uneven, due to the reaction force of the workpiece, the rotating ball drives the second sliding frame to move upward. Due to the arrangement of the limiting housing, the second sliding frame will move upward along the inner wall of the limiting housing, thereby stably pressing the different uneven surfaces of the workpiece. When the top end of one of the second sliding frames moves to the top of the inner wall of the limiting housing, the limiting housing will move upward. The limiting housing drives the first rotating bar to move upward, the first rotating bar drives the first slider to move upward. Limited by the sliding hole, the first slider slides along the inner wall of the sliding hole. The first slider drives the special-shaped plate to move, and the two special-shaped plates move closer to each other. The special-shaped plate drives the square shell to move, the square shell drives the square plate to move, and the square plate drives the clamping frame to move. During the process of the two clamping frames moving closer to each other, they can clamp the two sides of the workpiece, position the slight deviation that occurs during the flipping of the workpiece, and facilitate the accuracy of subsequent flipping. When the two clamping frames clamp the workpiece and the workpiece moves slightly, due to the rotating setting of the rotating ball, when the workpiece contacts the bottom of the rotating ball during the movement, the rotating ball will rotate, preventing the rotating ball from affecting the centering positioning of the workpiece when pressing the workpiece, and improving the operating stability of the centering positioning of the workpiece.

[0044] (3) In the present invention, when subjected to the reaction force of the workpiece, the clamping frame drives the square plate to move towards the inside of the square shell. The square plate drives the second rotating bar to move. Limited by the square shell, the second rotating bar drives the second slider to move along the inner wall of the square shell. The second slider drives the extrusion plate frame to move. During the movement of the extrusion plate frame, it will come into contact with the square bladder, causing the air flow inside the square bladder to enter the inside of the unidirectional flow tube. The air flow enters the inside of the fixed shell through the unidirectional flow tube. The air flow causes the first sliding frame inside the fixed shell to slide. The first sliding frame drives the flexible plate to move. The two separated flexible plates move closer to each other, thereby clamping the workpiece, further improving the stability of the workpiece during flipping, preventing the workpiece from shaking. And due to the setting of the unidirectional flow tube, the direction of gas flow is biased. That is to say, it flows smoothly when entering the inside of the fixed shell, while the flow in the opposite direction is restricted or blocked. Thus, when the workpiece moves above the conveyor belt at the other end, it no longer clamps the workpiece, and thus continues the transportation work of the workpiece.

[0045] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0091] A usage method of a flipping device for automobile part processing includes the following steps:

[0092] Step 1: Flip the workpiece, place the workpiece above the middle conveyor belt 14, start the first motor 11, the first motor 11 drives the first rotating shaft 12 to rotate, the first rotating shaft 12 drives the first roller 13 to rotate, the first roller 13 drives the conveyor belt 14 to rotate, the conveyor belt 14 drives the workpiece to be transported, the workpiece moves between the two flipping plates 44, turn off the first motor 11, start the second motor 41, the second motor 41 drives the second rotating shaft 42 to rotate, the second rotating shaft 42 drives the connecting plate 43 to rotate, the connecting plate 43 drives the flipping plate 44 to rotate, and the flipping plate 44 drives the workpiece to flip;

[0093] Step 2: Position the workpiece. When the surface of the workpiece to be pressed is uneven, due to the reaction force of the workpiece, the rotating ball 224 drives the second sliding frame 221 to move upward. Due to the setting of the limiting shell 222, the second sliding frame 221 will move upward along the inner wall of the limiting shell 222, so as to stably press different uneven surfaces of the workpiece. When the top of one of the second sliding frames 221 moves to the top of the inner wall of the limiting shell 222, the limiting shell 222 will move upward, the limiting shell 222 drives the first rotating bar 311 to move upward, the first rotating bar 311 drives the first slider 313 to move upward. Limited by the sliding hole 312, the first slider 313 slides along the inner wall of the sliding hole 312, the first slider 313 drives the special-shaped plate 314 to move, the two special-shaped plates 314 move closer to each other, the special-shaped plate 314 drives the square shell 321 to move, the square shell 321 drives the square plate 322 to move, the square plate 322 drives the clamping frame 323 to move, and during the process of the two clamping frames 323 moving towards each other, the two sides of the workpiece can be clamped;

[0094] Step 3: Improve the flipping stability of the workpiece. When affected by the reaction force of the workpiece, the clamping frame 323 drives the square plate 322 to move into the square shell 321, the square plate 322 drives the second rotating bar 331 to move. Limited by the square shell 321, the second rotating bar 331 drives the second slider 332 to move along the inner wall of the square shell 321, the second slider 332 drives the pressing plate frame 333 to move. During the movement of the pressing plate frame 333, it will contact the square bladder 45, so that the air flow inside the square bladder 45 enters the inside of the one-way flow tube 40, and the air flow enters the inside of the fixed shell 46 through the one-way flow tube 40. The air flow makes the first sliding frame 47 inside the fixed shell 46 slide, the first sliding frame 47 drives the flexible plate 48 to move, and the two separated flexible plates 48 move closer to each other, thereby clamping the workpiece.

[0095] During use, place the workpiece above the middle conveyor belt 14, start the first motor 11, the first motor 11 drives the first rotating shaft 12 to rotate, the first rotating shaft 12 drives the first roller 13 to rotate, the first roller 13 drives the conveyor belt 14 to rotate, and the conveyor belt 14 drives the workpiece to be transported. The workpiece moves between the two turning plates 44. Then, turn off the first motor 11 and start the second motor 41. The second motor 41 drives the second rotating shaft 42 to rotate, the second rotating shaft 42 drives the connecting plate 43 to rotate, the connecting plate 43 drives the turning plate 44 to rotate, and the turning plate 44 drives the workpiece to perform a turning operation. When the connecting plate 43 rotates a quarter of a circle, the workpiece moves above. Then, turn off the second motor 41 and start the first motor 11. The first motor 11 drives the next workpiece above the conveyor belt 14 for transportation work. At the same time, the first rotating shaft 12 drives the belt 210 to rotate, the belt 210 drives the cross bar 211 to rotate, and the cross bar 211 drives the reciprocating screw rods 212 with opposite threads to rotate. Due to the setting of the concave frame housing 20, the reciprocating screw rods 212 drive the threaded blocks 213 to move horizontally. At this time, during the process of the workpiece moving between the two turning plates 44, the threaded blocks 213 will perform a reciprocating motion for one cycle on the outer wall of the reciprocating screw rods 212. When the two threaded blocks 213 move closer to each other, the threaded blocks 213 drive the rotating plate 214 to move, the rotating plate 214 drives the lower pressing plate 215 to move vertically downward, the lower pressing plate 215 drives the second sliding frame 221 to descend, and the second sliding frame 221 drives the rotating ball 224 to descend, so that the rotating ball 224 presses the workpiece, thereby enabling the workpiece to be firmly stuck between the two turning plates 44 and improving the stability of the workpiece turning.

[0096] When the pressed surface of the workpiece is uneven, under the reaction force of the workpiece, the rotating ball 224 rotates to drive the second sliding frame 221 to move upward. Due to the setting of the limiting shell 222, the second sliding frame 221 will move upward along the inner wall of the limiting shell 222, so as to stably press different uneven surfaces of the workpiece. When the top of one of the second sliding frames 221 moves to the top of the inner wall of the limiting shell 222, the limiting shell 222 will move upward. The limiting shell 222 drives the first rotating bar 311 to move upward, and the first rotating bar 311 drives the first slider 313 to move upward. Limited by the sliding hole 312, the first slider 313 slides along the inner wall of the sliding hole 312. The first slider 313 drives the special-shaped plate 314 to move, and the two special-shaped plates 314 move closer to each other. The special-shaped plate 314 drives the square shell 321 to move, the square shell 321 drives the square plate 322 to move, and the square plate 322 drives the clamping frame 323 to move. During the process of the two clamping frames 323 moving towards each other, they can clamp both sides of the workpiece, position the slight deviation that occurs when the workpiece is flipped, and facilitate the accuracy of subsequent flipping. When the two clamping frames 323 clamp the workpiece, during the slight movement of the workpiece, due to the rotating setting of the rotating ball 224, when the workpiece contacts the bottom of the rotating ball 224 during the movement, the rotating ball 224 will rotate, preventing the rotating ball 224 from affecting the centering positioning of the workpiece when pressing the workpiece, and improving the operating stability of the workpiece centering positioning.

[0097] When under the reaction force of the workpiece, the clamping frame 323 drives the square plate 322 to move into the square shell 321. The square plate 322 drives the second rotating bar 331 to move. Limited by the square shell 321, the second rotating bar 331 drives the second slider 332 to move along the inner wall of the square shell 321. The second slider 332 drives the pressing plate frame 333 to move. During the movement of the pressing plate frame 333, it will contact the square bladder 45, causing the air flow inside the square bladder 45 to enter the inside of the one-way flow tube 40. The air flow enters the inside of the fixed shell 46 through the one-way flow tube 40. The air flow causes the first sliding frame 47 inside the fixed shell 46 to slide. The first sliding frame 47 drives the flexible plate 48 to move. The two separated flexible plates 48 move closer to each other, thereby clamping the workpiece, further improving the stability of the workpiece during flipping, preventing the workpiece from shaking. And due to the setting of the one-way flow tube 40, the direction of gas flow is biased. That is to say, it flows smoothly when entering the inside of the fixed shell 46, while the flow in the opposite direction is restricted or blocked. Thus, when the workpiece moves above the other conveyor belt 14, it no longer clamps the workpiece, and thus continues to transport the workpiece.
