Description

Technical Field

[0001] The present invention relates to the technical field of lifting equipment, and particularly relates to a floor sling for new energy vehicles and a lifting system. Background Art

[0002] The floor of a new energy vehicle is one of the components in the new energy vehicle chassis. During the production of new energy vehicles, a floor lifting system is required. The lifting system generally consists of a robotic arm and a manipulator, etc. After the manipulator clamps the vehicle floor, the floor is transported to the required position by the robotic arm.

[0003] The Chinese invention patent with the authorization announcement number CN112454398B discloses a vehicle floor sling and a lifting system. The vehicle floor sling includes a mounting frame and a control device. The mounting frame is movably installed with a first positioning portion in the horizontal direction and a second positioning portion in the vertical direction. The mounting frame is also provided with a clamping assembly. The above-mentioned prior art realizes the positioning of the vehicle floor, and cooperates with the clamping assembly to clamp the vehicle floor. Thus, by adjusting the positions of the first positioning portion and the second positioning portion, it is possible to meet the requirements of lifting vehicle floors of different models.

[0004] However, for the sling in the prior art, during the process of clamping and transporting the floor of a new energy vehicle, some relatively weak floors of new energy vehicles may undergo slight deformation due to the relatively large clamping force applied.

[0011] Preferably, the locking component b includes a spring two, a conical part, a spring three, a plug rod two, a rotating rod one, and a walking rod; One end of the second spring is installed at the bottom of the rectangular groove formed in the second clamping plate, and the other end thereof is connected to the conical part.

A first rotating rod pushed by the rising of the conical part is installed on the side surface of the second inserting rod. The first rotating rod is pushed, and the second inserting rod penetrates through the rectangular groove and contracts into the second jack on the third clamping plate inside the cavity of the second clamping plate.

[0015] Compared with the prior art, the above technical solutions of the present invention have the following beneficial technical effects: The first driving device drives the rectangular part to descend. The adsorption telescopic cylinder contacts the vehicle floor and is compressed. Subsequently, the second driving device is started to drive the bidirectional lead screw to rotate, thereby driving the two clamping parts to move towards the middle of the rectangular part along the axial direction of the round rod. At this time, the third clamping plate contacts the vehicle floor and is pushed back into the second clamping plate. The other third clamping plates are in contact with the vehicle floor up and down to limit its position. Subsequently, the second clamping plate and the first clamping plate in contact with the vehicle floor move towards the direction of the first elastic part. At this time, the walking rod drives the conical part to rise through the guidance of the chute, pushing the third spring out of the second clamping plate and inserting it into the second jack, so that the first clamping plate cooperates with the clamping part to clamp and limit the top and bottom of the vehicle floor. Subsequently, the first driving device drives the rectangular part to rise, thereby causing the pressing plate to press the lifting part downward, thereby causing the inclined surface to push the second rotating rod, and then inserting the first inserting rod into the first jack and the fourth jack to lock the positions of the first clamping plate and the second clamping plate, thus completing the clamping and limiting of the top and bottom of the vehicle floor by the clamping part and the first clamping plate, as well as the clamping of the left and right sides of the vehicle floor by the second clamping plate and the first clamping plate, and the clamping of the upper and lower sides of the vehicle floor by the third clamping plate, realizing the clamping and limiting of vehicle floors of different sizes.

[0016] And before clamping, the first clamping plate, the second clamping plate, and the third clamping plate do not apply a large force to the vehicle floor. After clamping, the positions of the first clamping plate, the second clamping plate, and the third clamping plate are locked, so that the first clamping plate, the second clamping plate, and the third clamping plate do not apply a force limit to the vehicle floor, thereby avoiding slight deformation of the vehicle floor due to heavy force, and at the same time ensuring the stability of clamping and limiting the vehicle floor.

[0017] When the first driving device drives the rectangular member to rise, it further drives the piston shaft to rise in the piston cylinder, and then pumps the air in the adsorption telescopic cylinder into the piston cylinder, making the pressure between the adsorption telescopic cylinder and the vehicle floor negative pressure, thereby assisting in limiting the vehicle floor and preventing the vehicle floor from shaking slightly between the first clamping plate, the second clamping plate, and the third clamping plate.

[0031] Embodiment 2, as Figure 1 shown, a floor sling for a new energy vehicle proposed by the present invention. Compared with Embodiment 1, the robotic arm mechanism in this embodiment has six-axis degrees of freedom. The robotic arm mechanism includes a robotic arm moving slide rail 1, a robotic arm body 2, a mounting frame 3, and a first driving device 4; One end of the robotic arm body 2 is arranged on the robotic arm moving slide rail 1 and moves along the robotic arm moving slide rail 1. The mounting frame 3 is installed at the other end of the robotic arm body 2. The first driving device 4 is installed in the mounting frame 3, and the output end of the first driving device 4 is connected to the rectangular part 5.

[0032] The robotic arm moving slide rail 1 drives the robotic arm body 2 to move, and the robotic arm body 2 drives the mounting frame 3 to move.

[0033] The second driving device 6 is a servo motor, and the first driving device 4 is a cylinder.

Compared with Embodiment 2, the adsorption mechanism of this embodiment includes a piston cylinder 30, a piston shaft 31, a circular tube 32, an adsorption telescopic cylinder 33 and a one-way air outlet valve 34; The piston cylinder 30 is installed in the mounting frame 3, and the large end of the piston shaft 31 is movably sleeved in its inner cavity; the small end of the piston shaft 31 penetrates through the piston cylinder 30 and is connected to the rectangular part 5; both ends of the circular tube 32 penetrate through the piston cylinder 30 and the adsorption telescopic cylinder 33 respectively, and the one-way air outlet valve 34 is installed on the circular tube 32.

[0035] Embodiment 4, as Figures 1-7 shown, a new energy vehicle floor lifting system proposed by the present invention. Compared with Embodiment 3, it includes the above-mentioned new energy vehicle floor lifting tool.

[0036] In summary, in the present invention, the robotic arm moving slide rail 1 drives the rectangular part 5 below the robotic arm body 2 to move to the vehicle floor. Then, the first driving device 4 is started to drive the rectangular part 5 to descend, so that the adsorption telescopic cylinder 33 contacts the vehicle floor, and the adsorption telescopic cylinder 33 is compressed. At the same time, the excess air is discharged from the one-way air outlet valve 34.

[0037] Subsequently, the driving device two 6 is started to drive the bidirectional lead screw 7 to rotate, thereby driving the clamping part 8 to move along the axial directions of the bidirectional lead screw 7 and the round rod 35. Then, the jack two 22 is driven to contact the two sides of the vehicle floor first, and further push the clamping plates three 21 on the left and right sides of the vehicle floor to contract into the clamping plate two 19. The clamping plates three 21 in contact with the upper and lower sides of the vehicle floor remain in place. Subsequently, the clamping plate one 11 and the clamping plate two 19 in contact with the vehicle floor are pushed towards the elastic part one 10. At this time, the clamping plate two 19 drives the walking rod 28 to move along the sliding groove 29. The walking rod 28 moves from the inclined section of the sliding groove 29 to the horizontal section of the sliding groove 29, so that the walking rod 28 drives the conical part 24 to move upward. The conical part 24 pushes the rotating rod one 27 to move, and then drives the inserting rod two 26 to penetrate out of the clamping plate two 19 and insert into one of the two jacks two 22 on the clamping plate three 21, thereby limiting and fixing the position of the clamping plate three 21. At this time, the clamping plates three 21 on the upper and lower sides of the vehicle floor are also fixed by the inserting rod two 26 and no longer move.

[0038] The clamping plate two 19 is pushed by the vehicle floor, so that the clamping part 8 and the clamping plate one 11 clamp and limit the top and bottom of the vehicle floor. Subsequently, after the jack one 12 on the pushed clamping plate one 11 is aligned with the inserting rod one 18, the clamping part 8 stops moving. Then, the driving device one 4 is started to drive the rectangular part 5 to rise. At this time, the bidirectional lead screw 7 drives the lifting part 16 to move upward, so that the lifting part 16 is pressed downward by the pressing plate 37, and then drives the inclined surface part 15 to descend. The descending inclined surface part 15 contacts the rotating rod two 38 on the inserting rod one 18, thereby pushing the rotating rod two 38 to drive the inserting rod one 18 to move towards the direction of the jack one 12 and insert into the jack one 12 and the jack four 36, thereby completing the locking and fixing of the positions of the jack one 12 and the clamping plate two 19, and realizing the limiting of the upper and lower sides, left and right sides, top and bottom of the vehicle floor by the clamping plate one 11, the clamping plate two 19 and the clamping plate three 21.

[0039] At the same time, by the upward movement of the rectangular part 5, the piston shaft 31 is driven to rise in the inner cavity of the piston cylinder 30, and then the air between the adsorption telescopic cylinder 33 and the vehicle floor is pumped into the piston cylinder 30, so that the adsorption telescopic cylinder 33 and the vehicle floor are in negative pressure, and then the vehicle floor is adsorbed by the adsorption telescopic cylinder 33 for auxiliary fixation, thereby preventing the subsequent slight shaking of the vehicle floor.

[0040] Then, the robotic arm moving slide rail 1 drives the robotic arm body 2 to move to a suitable position. Subsequently, the robotic arm body 2 drives the rectangular part 5 to rotate to a specified position, and then the driving device one 4 starts the rectangular part 5 to descend, and the driving device two 6 drives the bidirectional lead screw 7 to rotate so that the clamping plate three 21 gradually separates from the vehicle floor.

[0041] Moreover, through the settings of the locking component a and the locking component b, elastic members 10 and 20 with extremely small elastic force that can only drive the clamping plate 11, the clamping plate 19 and the clamping plate 21 to reset can be selected, ensuring that when clamping the vehicle floor, the force applied to the vehicle floor is extremely small, and through the settings of the locking component a and the locking component b, it can also be ensured that after clamping the vehicle floor, it will not separate from the vehicle floor due to the small clamping force.

[0042] At the same time, a plurality of jacks 12 on the clamping plate 11 and a plurality of jacks 36 on the clamping plate 19 can be provided, so that the movable distances of the clamping plate 11 and the clamping plate 19 can be adjusted according to the size of the vehicle floor to be clamped as required.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art to which the present invention pertains.
