During production, the bed is generally facing sideways. During the assembly process, the bed needs to be flipped over. The bed needs to be flipped 90° on the vertical plane first, and then flipped 90° on the horizontal plane. Generally, two cranes are used for the flipping work. However, in actual use, the flipping of parts will generate huge impact force, which can easily damage the sling and even cause the workpiece to fall. Summary of the Invention

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] like Figure 1-9 As shown, a turning mechanism for large parts includes a support frame 1, on which are provided:

[0037] A mounting plate 111 on which a synchronization block 135 and a shaft 117 are movably mounted;

[0038] Hydraulic rod 112;

[0039] The fixing member is used to fix the parts and cooperates with the above structures in the following manner:

[0040] The hydraulic rod 112 drives the fixed member to move upward through the synchronous block 135;

[0041] The synchronization block 135 drives the fixed member to rotate in the horizontal plane so that the shaft 117 is inserted into the fixed member;

[0042] The synchronous block 135 is separated from the fixed component, and the shaft 117 drives the fixed component to rotate on the vertical plane.

[0043] Specifically, when flipping a component, one crane is generally used to lift the component and drive it to rotate 90 degrees on the horizontal plane, and then the component is placed back on the workbench. Another crane is used to lift the component and drive it to rotate 90 degrees on the vertical plane. This is existing technology and will not be described in detail.

[0044] Furthermore, a tenon hole adapted to the shaft 117 is opened on the top plate 121; when flipping large parts, the hydraulic rod 112 is first extended to drive the fixed member to move down, and the fixed member fixes the parts. At this time, the hydraulic rod 112 is shortened, and the fixed member and the parts thereon are driven to move up through the mounting plate 111 and the synchronous block 135. When it rises to a height sufficient for the parts to rotate in the vertical plane, the synchronous block 135 is driven to drive the fixed member to rotate ninety degrees in the horizontal plane. At this time, the shaft 117 is facing the tenon hole on the fixing mechanism, and the shaft 117 is driven to move and insert into the fixing mechanism. Then the synchronous block 135 is separated from the fixing member. At this time, the shaft 117 can drive the fixing member to rotate ninety degrees in the vertical plane to realize the flipping of the parts. Then the hydraulic rod 112 is extended and retracted, driving the fixed member to move down, and placing the parts on the workbench. The flipping of the parts can be achieved with only one crane, and the impact force during the flipping process is also relatively small.

[0045] Furthermore, in the above embodiment, a plurality of movable locking blocks may be provided on the synchronization block 135. When the fixed member needs to be rotated in the horizontal plane, the locking blocks on the synchronization block 135 are inserted into the fixed member, and the synchronization block 135 can rotate with the fixed member. When the fixed member needs to be rotated in the vertical plane, the locking blocks on the synchronization block 135 are separated from the fixed member. At this time, the fixed member and the synchronization block 135 are loosened, and the fixed member can rotate in the vertical plane. Alternatively, a telescopic rod may be provided inside the mounting plate 111, and the synchronization block 135 is fixedly mounted on the telescopic rod. A groove adapted to the synchronization block 135 is provided on the fixed member. When the fixed member needs to be rotated in the horizontal plane, the telescopic rod is extended and the synchronization block 135 is inserted into the fixed member. At this time, the synchronization block 135 can rotate with the fixed member. When the fixed member needs to be rotated in the vertical plane, the telescopic rod is shortened and the synchronization block 135 is separated from the fixed member. At this time, the fixed member and the synchronization block 135 are loosened, and the fixed member can rotate in the vertical plane. Other structures that can be obtained by those skilled in the art based on common technical knowledge are also possible.

[0046] In the above technical solution, when flipping large parts, the hydraulic rod 112 is first extended to drive the fixed component to move down, and the fixed component fixes the parts. At this time, the hydraulic rod 112 is shortened, and the fixed component and the parts thereon are driven to move up through the mounting plate 111 and the synchronous block 135. When it rises to a height sufficient for the parts to rotate in the vertical plane, the synchronous block 135 is driven to drive the fixed component to rotate ninety degrees in the horizontal plane. At this time, the shaft rod 117 is facing the mortise hole on the fixing mechanism. The shaft rod 117 is driven to move and inserted into the fixing mechanism. Then the synchronous block 135 is separated from the fixed component. At this time, the shaft rod 117 can drive the fixed component to rotate ninety degrees in the vertical plane to realize the flipping of the parts. Then the hydraulic rod 112 is extended and retracted to drive the fixed component to move down and place the parts on the workbench. The flipping of the parts can be achieved with only one crane, and the impact force during the flipping process is also relatively small.

[0047] As a further embodiment provided by the present invention, the fixing member includes a top plate 121 movably mounted on the mounting plate 111 and a clamping plate 122 symmetrically and movably mounted on the top plate 121 , and an inserting block 128 for inserting components is provided on the clamping plate 122 .

[0048] Specifically, the splint 122 is provided with a tenon extending to the inside of the top plate 121, the insert block 128 is provided with reinforcing ribs to support and fix the parts, the insert block 128 is provided with a slope, and the bottom of the support frame 1 is provided with casters with brakes to facilitate the movement and fixation of the support frame 1.

[0049] Furthermore, when lifting the parts, the support frame 1 is first moved to the appropriate position, and the hydraulic rod 112 is driven to extend. The hydraulic rod 112 drives the mounting plate 111 and the top plate 121 to move downward, and the parts are located inside the top plate 121. At this time, the two clamps 122 on the top plate 121 are driven to approach the parts, and the plug 128 on the clamp 122 contacts the parts. The slope on the plug 128 rests on the parts and pushes the support frame 1 to slide, changing the relative position of the support frame 1 and the parts, so that the parts fit tightly on the top plate 121, the clamp 122 and the plug 128. At this time, the parts are fixed on the top plate 121. At this time, the top plate 121 and the parts can be driven to move upward by shortening the hydraulic rod 112.

[0050] As another embodiment further provided by the present invention, movable rods 114 are symmetrically provided on the mounting plate 111 , and shafts 117 are provided on the movable rods 114 . The top plate 121 rotates to retract the movable rods 114 and the shafts 117 into the mounting plate 111 .

[0051] Specifically, a spring is provided between the shaft rod 117 and the movable rod 114 , and a tenon hole adapted to the shaft rod 117 is provided on the top plate 121 .

[0052] Furthermore, when the top plate 121 rotates with the parts, the top plate 121 drives the shaft 117 to move, and the shaft 117 retracts into the movable rod 114. The top plate 121 continues to move, driving the movable rod 114 to retract into the mounting plate 111, making way for the movement path of the top plate 121. After the top plate 121 rotates ninety degrees with the parts, the top plate 121 and the movable rod 114 are staggered. At this time, the movable rod 114 extends from the mounting plate 111, and the shaft 117 on the movable rod 114 is inserted into the mortise on the top plate 121 under the action of the spring. At this time, the synchronization block 135 is separated from the top plate 121, and the top plate 121 can rotate with the parts around the shaft 117 as the axis, so that the parts rotate on the vertical plane.

[0053] As another embodiment further provided by the present invention, it also includes a wedge block 115 movably mounted on the mounting plate 111, and a pull rope 116 is arranged between the wedge block 115 and the shaft rod 117. When the movable rod 114 is facing the top plate 121, the wedge block 115 is staggered with the top plate 121, and the shaft rod 117 is inserted into the top plate 121.

[0054] Specifically, a spring is provided between the movable rod 114 and the mounting plate 111 , and a spring is provided between the wedge block 115 and the mounting plate 111 .

[0055] Furthermore, when the top plate 121 rotates, the top plate 121 moves along the slope of the wedge block 115 and pushes the wedge block 115 to move inside the mounting plate 111. The wedge block 115 drives the shaft 117 to move inside the movable rod 114 through the pull rope 116. After the shaft 117 is completely moved into the movable rod 114, the shaft 117 cannot move. The wedge block 115 continues to move and continues to pull the pull rope 116, driving the movable rod 114 to retract into the mounting plate 111, making way for the top plate. 121's moving path, after the top plate 121 rotates ninety degrees with the parts, the top plate 121 is staggered with the wedge block 115, the wedge block 115 extends from the mounting plate 111 under the action of the spring, the pull rope 116 is relaxed, and the movable rod 114 extends from the mounting plate 111 under the push of the spring, and is tightly attached to both sides of the top plate 121. The shaft rod 117 inside the movable rod 114 is inserted into the top plate 121 under the push of the spring. At this time, the top plate 121 can rotate with the shaft rod 117 as the axis.

[0056] As another embodiment further provided by the present invention, a plurality of first slide rods 124 and a plurality of second slide rods 125 are movably provided on the top plate 121. The plurality of first slide rods 124 move to insert into the annular groove on the mounting plate 111, and the plurality of second slide rods 125 move to fit closely against the synchronization block 135.

[0057] Specifically, a convex ring extending to the inside of the mounting plate 111 is provided on the top plate 121 , and a plurality of first sliding rods 124 and a plurality of second sliding rods 125 are movably provided inside the convex ring. The synchronization block 135 is specifically a polygonal prism.

[0058] Furthermore, during the upward movement of the top plate 121, the first slide bar 124 extends from the convex ring and is inserted into the annular groove on the mounting plate 111, and multiple second slide bars 125 abut against multiple side surfaces of the synchronous block 135. Multiple first slide bars 124 limit the top plate 121 from moving up with the mounting plate 111. At this time, the synchronous block 135 rotates, and the synchronous block 135 pushes multiple second slide bars 125, thereby driving the top plate 121 and the parts to rotate on the horizontal plane; when the parts need to rotate on the vertical plane, the shaft 117 is inserted into the top plate 121, and the first slide bar 124 and the second slide bar 125 on the top plate 121 move, and the first slide bar 124 and the second slide bar 125 are both retracted into the convex ring. At this time, the top plate 121 is separated from the mounting plate 111, and the top plate 121 can rotate on the horizontal plane with the shaft 117 as the axis.

[0059] As another embodiment further provided by the present invention, a gear ring 123 is movably provided inside the top plate 121 for driving a plurality of first slide bars 124 and second slide bars 125 to move. The shaft 117 is inserted into the top plate 121 and drives the gear ring 123 to rotate.

[0060] Specifically, a push block 127 is movably provided in the tenon hole on the top plate 121 , a first rack 126 meshing with the gear ring 123 is provided on the push block 127 , and a spring is provided between the push block 127 and the top plate 121 .

[0061] Furthermore, after the top plate 121 rotates ninety degrees on the horizontal plane with the parts, the shaft 117 on the movable rod 114 is inserted into the top plate 121 and pushes the push block 127. The push block 127 drives the first rack 126 to move, and the first rack 126 drives the gear ring 123 engaged with it to rotate, and then drives multiple first slide rods 124 and second slide rods 125 to move, retract into the convex ring, and the top plate 121 is separated from the mounting plate 111.

[0062] As another embodiment further provided by the present invention, two planar threads corresponding to the first slide rod 124 and the second slide rod 125 and in opposite directions are provided on the top surface of the gear ring 123, and the first slide rod 124 and the second slide rod 125 are both provided with sliding grooves adapted to the corresponding planar threads.

[0063] Specifically, when the shaft 117 is inserted into the top plate 121, the shaft 117 drives the first rack 126 to move through the push block 127, and the first rack 126 drives the gear ring 123 engaged therewith to rotate, and the flat thread on the gear ring 123 moves along the sliding grooves on the first slide bar 124 and the second slide bar 125. The two flat threads on the gear ring 123 push the first slide bar 124 and the second slide bar 125 respectively, so that the first slide bar 124 and the second slide bar 125 are retracted into the convex ring, so that the top plate 121 is separated from the mounting plate 111.

[0064] As another embodiment further provided by the present invention, a motor 131 is provided on the mounting plate 111, and a synchronous sleeve 133 adapted to the synchronous block 135 is axially slidably provided on the output end of the motor 131, and a winch 134 for driving the splint 122 to move is slidably provided on the synchronous sleeve 133.

[0065] Specifically, a synchronization rod 132 adapted to the synchronization sleeve 133 is provided on the output end of the motor 131 , and a spring is provided between the synchronization sleeve 133 and the mounting plate 111 .

[0066] Furthermore, when fixing the parts, the synchronization sleeve 133 is separated from the synchronization block 135. At this time, the motor 131 outputs torque, and drives the capstan 134 to rotate through the synchronization rod 132 and the synchronization sleeve 133. The capstan 134 drives the splint 122 to approach the parts and fix the parts on the top plate 121. When it is necessary to drive the parts to rotate on the horizontal plane, the synchronization sleeve 133 moves downward, spanning the synchronization rod 132, the synchronization block 135 and the capstan 134. At this time, the motor 131 outputs torque, drives the synchronization block 135 and the capstan 134 to rotate, and the synchronization block 135 drives the top plate 121 to rotate. The capstan 134 reels in the traction rope 143 released by the rotation of the top plate 121, so that the splint 122 tightly clamps the parts.

[0067] As another embodiment further provided by the present invention, the top plate 121 is internally provided with a gear 141 for driving the two clamping plates 122 to move relative to each other. A take-up drum 144 is provided on the gear 141, and a traction rope 143 is provided between the winch 134 and the take-up drum 144.

[0068] Specifically, a second rack 142 meshing with the gear 141 is provided on the tenon block of the clamping plate 122 .

[0069] Furthermore, when fixing the parts, the synchronization sleeve 133 is separated from the synchronization block 135. At this time, the motor 131 outputs torque, and drives the capstan 134 to rotate through the synchronization rod 132 and the synchronization sleeve 133. The capstan 134 reels the traction rope 143, causing the take-up drum 144 to release the traction rope 143 and rotate. The take-up drum 144 drives the gear 141 to rotate, and the gear 141 drives the splint 122 to approach the parts through the second rack 142 meshing with it, thereby fixing the parts on the top plate 121.

[0070] As another embodiment further provided by the present invention, the mounting plate 111 is internally provided with a push ring 137 for pushing the synchronous sleeve 133 to move, the push ring 137 is provided with a second push rod 138 extending to the top of the mounting plate 111, and the support frame 1 is provided with a push plate 113.

[0071] Specifically, the synchronization sleeve 133 is provided with a first push rod 136 that abuts against the push ring 137 , and there is magnetic attraction between the synchronization sleeve 133 and the synchronization block 135 .

[0072] Furthermore, when turning over large parts, the support frame 1 is first moved to a suitable position, and the hydraulic rod 112 is driven to extend. The hydraulic rod 112 drives the mounting plate 111 and the top plate 121 to move downward, and the parts are located inside the top plate 121. At this time, the synchronous sleeve 133 is separated from the synchronous block 135 under the push of the spring, and the motor 131 outputs torque, which drives the winch 134 to rotate through the synchronous rod 132 and the synchronous sleeve 133. The winch 134 reels in the traction rope 143, causing the take-up drum 144 to release the traction rope 143 and rotate. 144 drives the gear 141 to rotate, and the gear 141 drives the clamping plate 122 to approach the component through the second rack 142 meshing with it. The plug 128 on the clamping plate 122 contacts the component, and the slope on the plug 128 rests on the component, pushing the support frame 1 to move, changing the relative position of the support frame 1 and the component, so that the component is tightly fitted on the top plate 121, the clamping plate 122 and the plug 128. At this time, the component is fixed on the top plate 121, and then the caster brake of the support frame 1 is applied to fix the support frame 1;

[0073] The hydraulic rod 112 is driven to shorten, and the hydraulic rod 112 drives the mounting plate 111 to move upward. The multiple first sliding rods 124 on the top plate 121 are located in the annular grooves on the mounting plate 111. The top plate 121 moves upward along with the mounting plate 111. At the same time, the second push rod 138 on the mounting plate 111 gradually abuts against the bottom of the push plate 113 on the support frame 1. The push plate 113 pushes the second push rod 138 downward. The second push rod 138 drives the push ring 137 downward. The push ring 137 pushes the first push rod 136 and drives the synchronous sleeve 133 downward. The synchronous sleeve 133 spans the synchronous rod 132, the synchronous block 135 and the winch 134.

[0074] After the mounting plate 111 moves to a height sufficient for the top plate 121 and the parts to rotate on the vertical plane, the motor 131 outputs torque to drive the synchronous block 135 and the winch 134 to rotate. The synchronous block 135 drives the top plate 121 to rotate, and the winch 134 reels in the traction rope 143 released by the rotation of the top plate 121, so that the clamping plate 122 clamps the parts tightly. When the top plate 121 rotates, the top plate 121 moves along the slope of the wedge block 115 and pushes the wedge block 115 to move toward the inside of the mounting plate 111. The wedge block 115 drives the shaft 116 through the pull rope 116. 17 moves toward the inside of the movable rod 114. After the shaft 117 is completely moved into the inside of the movable rod 114, the shaft 117 cannot move, and the wedge 115 continues to move, and the pull rope 116 continues to be pulled, driving the movable rod 114 to retract into the mounting plate 111, making way for the moving path of the top plate 121. After the top plate 121 rotates 90 degrees with the parts, the top plate 121 and the wedge 115 are staggered, and the wedge 115 is extended from the mounting plate 111 under the action of the spring, the pull rope 116 is relaxed, and the movable rod 114 is extended from the mounting plate 111 under the push of the spring. The movable rod 114 is pushed out and is close to both sides of the top plate 121. The shaft 117 inside the movable rod 114 is inserted into the top plate 121 under the push of the spring. The push block 127 inside the top plate 121 is pushed by the shaft 117. The push block 127 moves toward the inside of the top plate 121 and drives the first rack 126 to move. The first rack 126 drives the gear ring 123 engaged with it to rotate. The flat thread on the gear ring 123 moves along the sliding groove on the first slide bar 124 and the second slide bar 125. The two flat threads on the gear ring 123 push the first slide bar 124 and the second slide bar 125 respectively. 125, so that the first slide bar 124 and the second slide bar 125 are retracted into the convex ring, so that the top plate 121 is separated from the mounting plate 111, and the synchronization block 135 is magnetically fixed in the synchronization sleeve 133. At this time, the traction rope 143 between the winch 134 and the take-up drum 144 pulls the top plate 121, and then the motor 131 outputs a reverse torque to drive the winch 134 to rotate in the opposite direction, releasing the traction rope 143 and slowly releasing the top plate 121. The top plate 121 and the components slowly rotate under the action of gravity, preventing the top plate 121 from moving quickly, and lowering the top plate 121 and the components;

[0075] Then the hydraulic rod 112 extends, driving the top plate 121 to move downward, so that the clamping plate 122 on the top plate 121 contacts the workbench. At this time, the lock of the support frame 1 is released, and the hydraulic rod 112 continues to extend, gradually placing the top plate 121 and the clamping plate 122 flat on the workbench. During this process, the component completes a 90-degree rotation on the vertical plane, completing the flipping process. At this time, the traction rope 143 can be further released to push the clamping plate 122 to separate the clamping plate 122 from the component.

[0076] The hydraulic rod 112 is shortened again to lift the mounting plate 111, and the top plate 121 is pushed at this time so that the top plate 121 fits the bottom of the mounting plate 111, and the wedge block 115 is slowly pressed. The wedge block 115 drives the shaft rod 117 to move to the outside of the top plate 121 through the pull rope 116, and the push block 127 moves with the first rack 126 under the push of the spring. The first rack 126 drives the first slide bar 124 and the second slide bar 125 to move through the ring gear 123. The first slide bar 124 is inserted into the annular groove on the mounting plate 111, and the second slide bar 125 is against the side wall of the synchronous block 135. The wedge block 115 is continued to be pressed. The wedge block 115 retracts the movable rod 114 into the mounting plate 111, and the top plate 121 is rotated to return it to its initial state, waiting for the next component flipping work.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
