Description

Technical Field

[0001] The utility model relates to the technical field of electric turning machines, in particular to an electric cantilever automatic bottom-supporting turning machine. Background Art

[0002] In the transformer industry, it is often necessary to flip the coils and stand them upright on a pallet. The traditional method in the industry is to use a hydraulic cylinder push-pull method. The hydraulic cylinder push-pull flipping is not suitable for working environments with cleanliness requirements because oil leakage from the hydraulic cylinder will pollute the environment.

[0003] In addition, in the transformer industry, there are many types of coil lengths, and the coil is usually required to be centered on the pallet. However, the industry currently generally adopts manual lifting to separate the coil from the pallet, place it on the L-shaped plate of the turning table, and then turn it over. This manual method of placing the coil is cumbersome to operate and takes a long time to complete, which seriously hinders automated production. Therefore, the utility model proposes an electric cantilever automatic bottom support and turning machine. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, the utility model proposes an electric flipping device capable of automatically supporting the bottom.

[0009] Preferably, an AGV guide is installed on the side of the flip mainboard frame assembly away from the base assembly, and the AGV guide is used to guide the AGV.

[0023] like Figure 1-Figure 4An electric cantilever automatic bottom supporting and flipping machine shown in the figure includes a base assembly 2, a flip mainboard frame assembly 1 is provided on the base assembly 2, and a rotating mechanism is installed on the base assembly 2, the rotating mechanism is used to drive the flip mainboard frame assembly 1 to rotate, a placing piece is provided on the side of the flip mainboard frame assembly 1 away from the base assembly 2, and the placing piece is used to place the workpiece, a bottom supporting assembly 3 is provided on the side of the flip mainboard frame assembly 1 away from the base assembly 2, the bottom supporting assembly 3 is used to resist the bottom of the workpiece, and a driving piece is installed on the flip mainboard frame assembly 1, and the driving piece is used to drive the bottom supporting assembly 3 to move.

[0024] Furthermore, the rotating mechanism includes a flip driving motor 7 installed on the base assembly 2, and the flip driving motor 7 drives the flip mainboard frame assembly 1 to rotate through the chain subassembly 8.

[0025] Furthermore, the rotating mechanism is other existing electric rotating equipment that can realize the rotation of the flip mainboard frame assembly 1.

[0026] Furthermore, the placement part includes two cantilevers 4 installed on the flip mainboard frame assembly 1, the two cantilevers 4 are symmetrically distributed and approximately symmetrically distributed, and the side of the cantilever 4 close to the bottom support assembly 3 is installed with a side guide 9, a front guide 10 and an electromagnet assembly 12. The workpiece is a coil on the steel pallet carrier surface, the side guide 9 and the front guide 10 are used for positioning the pallet, and the electromagnet assembly 12 is used for adsorption and fixation of the pallet, but the bottom support assembly 3 supports the coil.

[0027] The cantilever 4 serves as a carrier. The cantilever 4 can be freely selected in a certain range of up and down and left and right positions relative to the overall frame. Compared with the methods of oil cylinder push-pull and flipping around a cylindrical chain, at maximum load, the rotation axis can coincide with the center of gravity of the flipping mechanism, and the flipping force arm is close to zero, which greatly reduces the torque required for flipping. In addition, due to the use of a rotary worm gear reducer, compared with the sprocket transmission ratio of the flipping method around a cylindrical chain, the reduction ratio is larger and the flipping speed is faster. Moreover, due to the worm gear reducer with a larger reduction ratio, it has a self-locking ability, and the flipping action is safer.

[0028] The utility model adopts the cantilever 4 as a platform for carrying, and provides an AGV entry and exit space under the cantilever 4, which can automatically carry out AGV docking and picking, and is provided with a bottom supporting component driven by a screw rod 6 to support the bottom of workpieces of different lengths within a certain range for flipping. The steps of manually lifting the workpiece off the pallet and placing it on the flipping device are reduced, which greatly improves production efficiency and reduces the space occupied by the equipment.

[0029] Furthermore, the driving member comprises a base driving motor 5 , a screw rod 6 is mounted on the output shaft of the base driving motor 5 via a coupling, and the base assembly 3 is sleeved on the screw rod 6 .

[0030] Furthermore, the driving member is other existing pushing devices that can drive the bottom support assembly 3 to move horizontally.

[0031] Furthermore, an AGV guide 11 is installed on the side of the flip mainboard frame assembly 1 away from the base assembly 2, and the AGV guide 11 is used to guide the AGV, so that the device can cooperate with the AGV vehicle to achieve automatic flipping including transportation.

[0032] The proposed electric cantilever automatic bottom supporting and flipping machine uses a placement piece to place and fix the workpiece. The driving piece drives the bottom supporting assembly 3 to move and contact the bottom of the workpiece. The rotating mechanism drives the flipping mainboard frame assembly 1 to rotate, thereby driving the workpiece to flip. The flipping action is completed automatically without manual operation, thereby improving work efficiency. The driving piece and the rotating mechanism are both electrically driven to avoid oil pollution to the working environment. It can cooperate with AGV to automatically pick up and place pallet workpieces, is compatible with workpieces within a certain range of lengths, and can bottom support and flip the workpiece centered on the pallet.

[0033] In the prior art, the sprocket drives the chain around the outer edge of the cylinder, the cylinder diameter is large, and the bottom of the workpiece is high above the ground after flipping, which is not conducive to working in a space with a gantry crane manipulator. The device adopts a method in which the rotation axis is externally placed on both sides of the flip, and the height of the flip axis can be freely selected, so that the bottom of the flipped workpiece is very close to the ground, which is conducive to flipping the workpiece in a space with a lower height limit, and can flip the workpiece in a space with a gantry crane manipulator with a lower height limit.

[0034] During the working process of this embodiment:

[0035] When in use, the AGV enters the pick-up and placement position through the AGV guide 11, lifts the fully loaded steel pallet to the top of the cantilever 4, the AGV platform descends, and the pallet falls on the cantilever through the side guide 9 and the front guide 10. The electromagnet assembly 12 is energized to attract the steel pallet, and the AGV detaches from the pallet and leaves empty, completing the pallet positioning action.

[0036] The bottom support driving motor 5 drives the screw rod 6, and the bottom support assembly 3 is pressed against the bottom of the workpiece according to the length of the workpiece. The bottom support driving motor 5 is braked to lock the screw rod 6, and the bottom support action is completed. Figure 2 .

[0037] The flip driving motor 7 drives the chain subassembly 8 to flip the flip mainboard frame assembly 1 90 degrees. After flipping in place, the worm gear reducer of the base assembly 2 is self-locking, locking the flipping action of the flip mainboard frame assembly 1, and completing the flipping action. Figure 3 .

[0038] After the workpiece is removed by manual lifting, the flip drive motor 7 drives the chain subassembly 8 to flip and reset the flip mainboard frame assembly 1 90 degrees. The reducer of the base assembly 2 is self-locking, locking the flipping action of the flip mainboard frame assembly 1, and completing the flip reset action. The power-on state of the electromagnet assembly 12 and the brake state of the bottom support drive motor 5 are stopped at the same time, and the bottom support drive motor 5 drives the screw 6 to reset the bottom support assembly 3, completing the bottom support reset action. The AGV enters the waiting position under the cantilever through the AGV guide 11, lifts and transports the empty steel pallet, and completes the entire process.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
