DETAILED DESCRIPTION

[0042] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings. It should be noted that the following is only for illustration and not for limitation of the present invention. The lifting device of the present invention can be used in a production line, especially in an automated production line.

[0043] The lifting device can be used on the production line to lift the workpiece pallet on the conveyor line, so that the workpiece pallet can be separated from the conveyor line for processing the workpiece on the pallet. The workpiece pallet has a tooling plate for placing the workpiece; the tooling plate can be rotated so that the workpiece on the tooling plate can be processed on different sides.

[0044] Reference Figure 1-Figure 5 , Figure 1 The structure of a lifting device 100 is schematically shown. The lifting device 100 includes a lifting mechanism 1 and a driving mechanism 2. The lifting mechanism 1 has a first top plate 11 and a second top plate 12. The first top plate 11 is located above the second top plate 12. The first top plate 11 and the second top plate 12 can be slidably connected, and the first top plate 11 can move relative to the second top plate 12.

[0045] The driving mechanism 2 has a driving source 21, a pillar 22 and a column 23. The driving source 21 has a main body 211 and an actuating member 212. The actuating member 212 can move relative to the main body 211. The actuating member 212 has a driving rod 2121 and a lifting plate 2122. The driving rod 2121 and the lifting plate 2122 are fixed or integrally arranged. The lifting plate 2122 is located below the first top plate 11, and the top plate can drive the first top plate 11 to move.

[0046] The column 23 is located on the lifting plate 2122, and the column 23 and the lifting plate 2122 are fixed or integrally arranged. The pillar 22 is located on the lifting plate 2122, and the pillar 22 and the lifting plate 2122 are fixed or integrally arranged. The column 23 and the pillar 22 are located on the side of the lifting plate 2122 away from the driving rod 2121, and the column 23 and the pillar 22 have different protrusion heights relative to the lifting plate 2122. The first top plate has a slot 112 and a middle notch 113, and there can be multiple slots 112. The position of the slot 112 corresponds to the column 23, and the position of the middle notch 113 corresponds to the pillar 22. When the lifting device is used for lifting, the column 23 can extend out of the first top plate from the position of the slot 112, and the pillar 22 can extend out of the first top plate from the position of the middle notch 113.

[0047] The columns 23 and the pillars 22 can be used to support the tooling plate of the pallet. When the tooling plate on the pallet is in one position, the columns 23 can be used to contact the tooling plate to provide support during jacking. When the tooling plate on the pallet is rotated to another position, the pillars 22 can be used to contact the other side of the tooling plate to provide support during jacking. In this way, the jacking device can be applied to a pallet with a flipping function, so that when the workpiece on the pallet is processed on different sides, the jacking device can provide support, which helps to protect the workpiece from the pallet during processing and improves the service life of the pallet.

[0048] The jacking device has a height-fixing mechanism 3, which has a first height-fixing component 31. The first height-fixing component 31 is located on the second top plate 12. The first height-fixing component 31 has at least two first height-raising components 311. The two first height-raising components 311 are arranged on both sides of the driving mechanism 2. Each first height-raising component 311 has a first driving cylinder 312 and a first cushion block 313. The driving shaft of the first driving cylinder 312 and the first cushion block 313 are fixed or integrated or limitedly arranged. The first cushion block 313 can move under the action of the first driving cylinder 312. The cylinder body of the first driving cylinder 312 is fixed to the second top plate 12; in the jacking state of the jacking device, the lifting plate 2122 is supported on the first cushion block 313.

[0049] When the workpiece needs to be processed after being lifted, the lifting device is in a lifting state. Since the lifting device also has a height-fixing mechanism 3, the first pad 313 can be used to contact and offset the lifting plate 2122, and can be used to share the column 23 or the force exerted on the column 23, so that the force applied to the tooling plate during the workpiece processing can be balanced to the first pad 313, which is beneficial to improving the service life of the driving mechanism 2.

[0050] The lifting plate 2122 is connected to the first supporting column 2123 . When the lifting device is in the lifting state, the first cushion block 313 is located below the first supporting column 2123 , and the first supporting column 2123 is supported by the first cushion block 313 .

[0051] When the lifting device is in the lifting state, the lifting plate 2122 is forced to move upward, and the lifting plate 2122 drives the first top plate 11 upward to limit the first top plate 11 and the workpiece pallet. When the lifting plate 2122 rises, it drives the first support column 2123 upward, so that space is left under the first support column 2123. The first cushion block 313 can be moved to the bottom of the first support column 2123 under the action of the first driving cylinder 312. In this way, the lifting plate 2122 can be supported on the first cushion block 313, so that the force exerted on the lifting plate 2122 can be shared by more fulcrums, thereby reducing the force exerted by the lifting plate 2122 on the drive mechanism 2 during workpiece processing.

[0052] The columns 23 are located around the lifting plate 2122 and protrude relative to the lifting plate 2122 . The pillars 22 are located in the middle of the lifting plate 2122 and protrude relative to the lifting plate 2122 . The protruding height of the columns 23 is greater than the protruding height of the pillars 22 .

[0053] The columns 23 and the pillars 22 are located at different positions of the lift plate 2122. The columns 23 are located around the lift plate 2122. There can be multiple columns 23, for example, four. The columns 23 can be used to contact the back side of the tooling plate, and the side of the tooling plate used to place the workpiece is defined as the front side. The four columns 23 and the planar contact support of the tooling plate effectively and advantageously transfer and share the force when processing the workpiece. The pillars 22 are located in the middle of the lift plate 2122. When the tooling plate is flipped, for example, rotated 90°, the side of the tooling plate will move above the lift plate 2122 and face the lift plate 2122. At this time, the pillars 22 are in the middle of the lift plate 2122 and can contact and resist the side of the tooling plate.

[0054] In this article, above and below refer to the direction along which Figure 1 The direction of the height direction H.

[0055] The second top plate 12 has a receiving area 121, and the outer contour of the lifting plate 2122 is smaller than the receiving area 121, and the lifting plate 2122 can pass through the receiving area 121 during the movement. The height of the column 23 is greater than the distance between the first top plate 11 and the second top plate 12, so that the lifting plate 2122 can pass through the receiving area 121 from below under force, pushing the first top plate 11 upward, so that the column 23 or the support 22 can contact the tooling plate.

[0056] The lifting device has a base frame 4, the lifting mechanism 1 can move relative to the base frame 4, the base frame 4 has a bottom plate 43, the base frame 4 has a buffer 41, the buffer 41 protrudes relative to the bottom plate 43 toward the second top plate 12, and the buffer 41 is located below the first support column 2123. When the lifting plate 2122 is reset, the lifting plate 2122 moves downward, and a part of the lifting plate 2122 contacts the buffer 41, providing a buffer for the lifting plate 2122, thereby reducing the damage of the lifting plate 2122 to the bottom plate during the descending process.

[0057] When the above-mentioned lifting device is in use, the actuating member 212 of the driving mechanism 2 is actuated to drive the lifting plate 2122 to move upward, and the lifting plate 2122 drives the first top plate 11 to move upward, and the limiting pin 111 on the first top plate 11 can be used to limit the position with the pallet. The first driving cylinder 312 pushes the first cushion block 313 to move, so that the first cushion block 313 is located below the first support column 2123. The first cushion block 313 provides a support point below the first support column 2123, so that the first top plate 11 cannot automatically fall back after being lifted. The protruding column 23 above the lifting plate 2122 can contact the tooling plate of the pallet and is used to support the tooling plate.

[0058] After the workpiece on the pallet is processed, the first driving cylinder 312 is reset, the first cushion block 313 leaves the bottom of the first support column 2123, the lifting plate 2122 moves down along with the actuating member 212 of the driving mechanism 2, and the first top plate 11 falls back. At this time, the tooling plate can be flipped. After the flipping is completed, the actuating member 212 of the driving mechanism 2 is actuated to drive the lifting plate 2122 to move upward again, and the lifting plate 2122 drives the first top plate 11 to move upward, and the limiting pin 111 on the first top plate 11 can be used to limit the position with the pallet. The first driving cylinder 312 pushes the first cushion block 313 to move, so that the first cushion block 313 is located below the first support column 2123, and the first cushion block 313 provides a support point below the first support column 2123, so that the first top plate 11 cannot automatically fall back after being lifted. The pillar 22 protruding above the lifting plate 2122 can contact the tooling plate after flipping, and is used to support the tooling plate.

[0059] In this way, the jacking device can be used to lift the overturned pallet, and for the overturned pallet, since the tooling plate is in a suspended state, the columns 23 or pillars 22 of the jacking device can be used to support the tooling plate at different positions, so that when the workpiece on the tooling plate is processed, the strong impact applied can be shared by the pillars 22 or columns 23, which can be beneficial to the service life of the pallet.

[0060] As another embodiment, refer to Figure 6-Figure 11 , Figure 6 The structure of the lifting device 200 is schematically shown. The lifting device 200 comprises a base frame 4, a lifting mechanism 1, a driving mechanism 2 and a height setting mechanism 3.

[0061] The lifting mechanism 1 can move relative to the base frame 4. The base frame 4 has a bottom plate and a guide column 42. The guide column 42 is located on the bottom plate. The lifting mechanism 1 and the guide column 42 are fixed.

[0062] The lifting mechanism 1 has a first top plate 11 and a second top plate 12. The first top plate 11 has a limit pin 111, and the limit pin 111 is used to limit the position of the tray to be lifted. The distance between the first top plate 11 and the second top plate 12 is variable, that is, the first top plate can move relative to the second top plate, specifically move upward and reset. The second top plate 12 has a accommodating area 121 for accommodating part of the structure of the driving mechanism 2.

[0063] The driving mechanism 2 has a driving source 21, a pillar 22 and a column 23. The driving source 21 has a main body 211 and an actuating member 212, the actuating member 212 can move relative to the main body 211, and the actuating member 212 has a driving rod 2121 and a lifting plate 2122, and the driving rod 2121 and the lifting plate 2122 are fixed or integrally arranged. The column 23 is located on the lifting plate 2122, and the column 23 and the lifting plate 2122 are fixed or integrally arranged, and the pillar 22 is located on the lifting plate 2122, and the pillar 22 and the lifting plate 2122 are fixed or integrally arranged. The column 23 and the pillar 22 are located on the side of the lifting plate 2122 away from the driving rod 2121. The outer contour of the lifting plate 2122 is smaller than the accommodating area 121 of the second top plate 12, and the lifting plate 2122 can pass through the accommodating area 121 during the movement. The bottom plate 43 has a notch for accommodating the driving rod 2121 so that the driving rod 2121 can pass through the bottom plate and move up and down.

[0064] The column 23 and the support 22 can extend out of the first top plate 11. There can be multiple columns 23. The column 23 can be used to abut against one side of the tooling plate of the pallet. When the tooling plate of the pallet is flipped, the support 22 can be used to abut against one side of the flipped tooling plate. In this way, the lifting device can be used to provide support force before and after flipping, so that the lifting device can be used to lift the pallet at different positions, so that subsequent processing operations, such as press fitting, grinding, stamping, etc., are supported by the drive mechanism 2, reducing the force on the pallet and increasing the service life of the pallet.

[0065] The height setting mechanism 3 includes a first height setting component 31 and a second height setting component 32. The first height setting component 31 is located on the second top plate 12, and the second height setting component 32 is located on the bottom plate. Figure 5 The second height setting component 32 can refer to Fig.10 .

[0066] The first height-fixing component 31 has at least two first height-raising components 311 . The two first height-raising components 311 are disposed on both sides of the driving mechanism 2 to provide a balanced supporting force.

[0067] Each first heightening component 311 has a first driving cylinder 312, a first moving member 314, a first cushion block 313, and a first sliding matching plate 315. The driving shaft of the first driving cylinder 312 and the first moving member 314 are fixed, and the first moving member 314 can move under the action of the first driving cylinder 312. The first cushion block 313 and the first moving member 314 are fixed or integrated or limited, and the first sliding matching plate 315, the cylinder body of the first driving cylinder 312, and the second top plate 12 are fixed, so that the first cushion block 313 can move relative to the first sliding matching plate 315. The first cushion blocks 313 of the two first heightening components 311 can move closer to or farther away from each other under the action of their respective first driving cylinders 312.

[0068] The second height-fixing component 32 also has at least two second height-raising components 321 . The two second height-raising components 321 are respectively arranged on both sides of the driving mechanism 2 to provide a balanced supporting force.

[0069] Each second heightening component 321 has a second driving cylinder 322, a second moving member 324, a second cushion block 323, and a second sliding matching plate 325. The driving shaft of the second driving cylinder 322 and the second moving member 324 are fixed, and the second moving member 324 can move under the action of the second driving cylinder 322. The second cushion block 323 and the second moving member 324 are fixed or integrated or limited, and the second sliding matching plate 325, the cylinder body and the bottom plate of the second driving cylinder 322 are fixed, so that the second cushion block 323 can move relative to the second sliding matching plate 325. The second cushion blocks 323 of the two second heightening components 321 can move closer to or farther from each other under the action of their respective second driving cylinders 322.

[0070] The lifting plate 2122 is connected to the first supporting column 2123. When the first cushion blocks 313 of the first height fixing assembly 31 are close to each other, the first cushion blocks 313 can be located below the first supporting column 2123 to provide a supporting force for the first supporting column 2123. In this way, the positions of the first top plate 11 and the second top plate 12 can be kept unchanged by the first supporting column 2123 and the first cushion blocks 313.

[0071] It should be understood that moving the two first pads 313 close to each other is only one way of moving. The two first pads 313 can also move independently. It only needs to be that the first pad 313 can be located under the first support column 2123 when needed, such as when jacking, so that the first support column 2123 can be supported on the first pad 313.

[0072] The jacking device has a base frame 4, the jacking mechanism 1 can move relative to the base frame 4, and the base frame 4 has a bottom plate; the height fixing mechanism 3 has a second height fixing component 32, and the second height fixing component 32 also has at least two second height raising components 321. The two second height raising components 321 are arranged on both sides of the driving mechanism 2, and each second height raising component 321 has a second driving cylinder 322 and a second cushion block 323. The driving shaft of the second driving cylinder 322 and the second cushion block 323 are fixed or integrated or limitedly arranged. The second cushion block 323 can move under the action of the second driving cylinder 322, and the cylinder body and the bottom plate of the second driving cylinder 322 are fixed.

[0073] In the middle state of the lifting device, the second cushion block 323 is located below the second support column 14, and the first top plate 11 is supported on the second cushion block 323. The middle state of the lifting device is the state when the tray above the lifting device is ready to flip.

[0074] The lifting mechanism 1 has a guide sleeve 13 and a second support column 14. The guide sleeve 13 is at least partially located between the first top plate 11 and the second top plate 12. The guide sleeve 13 and the second top plate 12 are fixed or integrated or limited. The second support column 14 is accommodated in the guide sleeve 13 and can move up and down relative to the guide sleeve 13. When the first top plate 11 moves upward, the first top plate 11 drives the second support column 14 to move upward relative to the guide sleeve 13. At this time, there is space under the second support column 14. The second driving cylinder 322 can push the second cushion block 323 to cushion the second cushion block 323 under the second support column 14 to provide support for the first top plate 11. In this way, the position between the first top plate 11 and the bottom plate can be kept unchanged by the second support column 14 and the second cushion block 323.

[0075] In this way, when the tooling plate needs to be flipped, the first driving cylinder 312 of the first height fixing component 31 is reset, the first cushion block 313 leaves the space under the first support column 2123, the driving mechanism 2 moves downward, and the lifting plate 2122 moves downward. At this time, the first top plate 11 can still maintain its position unchanged through the action of the second support column 14 and the second cushion block 323 of the second height fixing component 32. In this way, even if the tooling plate needs to be flipped, the lifting device can still lift the first top plate 11 and limit it to the pallet. In this way, the position of the pallet is more precise when flipping.

[0076] As another embodiment, the lifting mechanism 1 has a guide rod 15 , and the guide rod 15 may be a telescopic structure. The first top plate 11 drives the guide rod 15 to telescopically move, thereby realizing relative position movement between the first top plate 11 and the second top plate 12 .

[0077] When the above-mentioned lifting device is in use, the actuating member 212 of the driving mechanism 2 is actuated to drive the lifting plate 2122 to move upward, and the lifting plate 2122 drives the first top plate 11 to move upward, and the limiting pin 111 on the first top plate 11 can be used to limit the position with the pallet. The first driving cylinder 312 pushes the first cushion block 313 to move, so that the first cushion block 313 is located below the first support column 2123. The first cushion block 313 provides a support point below the first support column 2123, so that the first top plate 11 cannot automatically fall back after being lifted. The protruding column 23 above the lifting plate 2122 can contact the tooling plate of the pallet and is used to support the tooling plate.

[0078] The second driving cylinder 322 pushes the second cushion block 323 to move, so that the second cushion block 323 is located below the second support column 14. The second cushion block 323 provides a support point below the second support column 14, so that the first top plate 11 cannot automatically fall back after being lifted.

[0079] After processing the workpiece on the pallet, the first driving cylinder 312 is reset, the first cushion block 313 leaves the first supporting column 2123, the lifting plate 2122 moves downward along with the actuating member 212 of the driving mechanism 2, and the first top plate 11 is supported by the second cushion block 323 to maintain its position unchanged.

[0080] As the lifting plate 2122 moves downward, the pillars 23 and the support posts 22 also move downward, providing space for the tooling plate to flip, and the tooling plate can now flip. After the flipping is completed, the actuating member 212 of the driving mechanism 2 is actuated to drive the lifting plate 2122 to move upward again, and the support posts 22 protruding above the lifting plate 2122 can contact the flipped tooling plate to support the tooling plate. The first driving cylinder 312 pushes the first cushion block 313 to move, so that the first cushion block 313 is located below the first support post 2123, and the first cushion block 313 provides a support point below the first support post 2123.

[0081] In this way, the jacking device can be used to lift the overturned pallet, and for the overturned pallet, since the tooling plate is in a suspended state, the columns 23 or pillars 22 of the jacking device can be used to support the tooling plate at different positions, so that when the workpiece on the tooling plate is processed, the strong impact applied can be shared by the pillars 22 or columns 23, which can be beneficial to the service life of the pallet.
