DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1-6 shown, an aluminum ingot gripping device includes a driving seat 1. A set of lead screws 3 are respectively key-connected and installed at the output ends on the left and right sides of the driving seat 1. Two sets of limiting seats 5 are symmetrically bolted and installed on the left and right sides of the driving seat 1. An inner slider 7 is slidably installed inside the limiting seat 5. By controlling the rotation of the lead screw 3 by the driving seat 1, the inner slider 7 can stably slide inside the limiting seat 5, so as to control the relative movement of two sets of protective pads 28 to complete the clamping work of the aluminum ingot.

[0027] A limiting rod 8 is fixedly installed at the bottom of the inner slider 7. A positioning block 9 is fixedly installed at the bottom end of the limiting rod 8. A rotating disk 13 is rotatably installed on one side of the positioning block 9. A cover plate 23 is snap-fitted and installed on the outer side of the rotating disk 13. A protective pad 28 is adhered to the outer side of the cover plate 23. The limiting rod 8 installed at the bottom of the inner slider 7 is used to fix the use position of the protective pad 28. At the same time, the rotatable rotating disk 13 installed on one side of the positioning block 9 can control the rotation of the protective pad 28 to fit the surface of the aluminum ingot, so as to better provide the force-bearing strength for the clamping of the aluminum ingot.

[0028] Two sets of L-shaped supporting plates 19 are rotatably installed at the rear side of the rotating disk 13. A set of electric drives 25 are respectively installed at the positions corresponding to the two sets of L-shaped supporting plates 19 inside the rotating disk 13 and the cover plate 23. An internal thread tube 26 is key-connected and installed at the bottom of the electric drive 25. A threaded rod 27 is threadedly installed inside the internal thread tube 26. The end of the threaded rod 27 is threadedly turned into the L-shaped supporting plate 19. The L-shaped supporting plate 19 installed at the rear side of the rotating disk 13 rotates to apply a supporting force to the bottom of the aluminum ingot, so as to reduce the protection for the clamping of the aluminum ingot during the overall use process of the device. At the same time, by the rotation of the threaded rod 27 and the threaded connection with the L-shaped supporting plate 19, the force-bearing strength of the threaded rod 27 can be further improved.

[0029] Further, an electric push rod 2 is bolted and installed at the top end of the driving seat 1. An L-shaped force-bearing bracket 6 is bolted and installed on the upper surface of each limiting seat 5. The side surface of the L-shaped force-bearing bracket 6 is bolted and installed with the driving seat 1. A rotating seat 4 is rotatably installed at the end of the lead screw 3. The rotating seat 4 is fixedly installed inside the limiting seat 5. The electric push rod 2 at the top end of the driving seat 1 can control the gripping height of the aluminum ingot, so that the aluminum ingot can be smoothly clamped and transported. The L-shaped force-bearing bracket 6 installed on the upper surface of the limiting seat 5 ensures the overall use strength of the limiting seat 5. Cooperating with the rotating lead screw 3, the overall movement of the inner slider 7 is more stable, and further better controls the movement and use state of the two sets of protective pads 28.

[0030] Furthermore, a set of extension plates 10 are respectively installed on the corresponding sides of the two groups of positioning blocks 9. A set of first electric drive rotating shafts 11 are installed through the middle of each set of extension plates 10. Two sets of support springs 12 are respectively installed on the corresponding sides of the two sets of extension plates 10. The extension plates 10 installed on one side of the positioning block 9 limit the first electric drive rotating shaft 11 and the support springs 12. The rotation angle of the rotating disc 13 can be locked by the first electric drive rotating shaft 11. At the same time, the two sets of support springs 12 provided can assist the rotating disc 13 to rotate, so that the rotating disc 13 can fit more firmly on the surface of the aluminum ingot.

[0031] Furthermore, a connecting seat 14 is fixedly installed in the middle of the outer side of each set of rotating discs 13. A positioning ear plate 15 is fixedly installed on the outer side of the connecting seat 14. The positioning ear plate 15 is sleeved and installed with the first electric drive rotating shaft 11. Two sets of inclined slots 16 are symmetrically opened on the upper and lower sides of the middle of the connecting seat 14. Two sets of hydraulic telescopic brackets 17 are rotatably installed inside each set of inclined slots 16. The connection between the positioning ear plate 15 installed on the outer side of the connecting seat 14 and the first electric drive rotating shaft 11 can control the rotation of the rotating disc 13. The inclined slots 16 opened on the surface of the connecting seat 14 limit the use angle of the hydraulic telescopic brackets 17. The rotation angle of the rotating disc 13 is further controlled by pulling the side extension plate 10 through the hydraulic telescopic brackets 17.

[0032] Furthermore, each group of support springs 12 is fixedly connected to the corresponding side of the rotating disc 13. The telescopic ends of each group of hydraulic telescopic brackets 17 are rotatably connected to the extension plate 10. The support springs 12 and the hydraulic telescopic brackets 17 cooperate to limit the rotation of the rotating disc 13. After the protective pad 28 fits on the surface of the aluminum ingot, the fitting state can be increased, and the problem of the aluminum ingot slipping off can be avoided.

[0033] Furthermore, two sets of second electric drive rotating shafts 18 are symmetrically installed on the outer side of the rotating disc 13. Each group of L-shaped support plates 19 is installed on the surface of the second electric drive rotating shaft 18 at the corresponding position. A positioning rod 20 is fixedly installed on the outer side of the rotating disc 13 above each group of second electric drive rotating shafts 18. The second electric drive rotating shafts 18 installed on the outer side of the rotating disc 13 can control the rotation of the L-shaped support plates 19, so that the L-shaped support plates 19 can lift and limit the aluminum ingot clamped from the bottom, reduce the use intensity of the first electric drive rotating shaft 11 and the second electric drive rotating shaft 18, and avoid the problem of the aluminum ingot slipping off, improving the use safety of the device.

[0034] Furthermore, a jack 21 is penetrated and opened at the position of the L-shaped support plate 19 corresponding to the positioning rod 20, and a threaded hole 22 is penetrated and opened at the position of the L-shaped support plate 19 corresponding to the threaded rod 27. The jack 21 opened on one side of the L-shaped support plate 19 is inserted into the positioning rod 20 to complete the limit of the L-shaped support plate 19 when the L-shaped support plate 19 is not in use. During the rotation and use process of the L-shaped support plate 19, the use intensity of the threaded rod 27 is improved through the threaded connection between the threaded rod 27 and the threaded hole 22.

[0035] Furthermore, two groups of limiting frames 24 are symmetrically installed inside the rotating disc 13 and the cover plate 23. The electric drive 25 is bolted inside the limiting frame 24, and the threaded rod 27 extends out from the bottom of the rotating disc 13 and the cover plate 23. The provided limiting frame 24 limits the electric drive 25. The electric drive 25 controls the rotation of the internally threaded tube 26. Since the threaded rod 27 is threadedly installed with the rotating disc 13 and the cover plate 23, when the internally threaded tube 26 rotates, the threaded rod 27 can rotate downward without idling, enabling the threaded rod 27 to stably rotate into the threaded hole 22 to fix the using position of the L-shaped support plate 19.

[0036] Working principle: By rotating the lead screw 3, the two groups of protective pads 28 are controlled to move relatively to fit and clamp the surface of the aluminum ingot. When the surface of the aluminum ingot is inclined, as the clamping force continuously increases, the protective pads 28 are inclined. The provided support spring 12 and the hydraulic telescopic bracket 17 are used to assist the rotation of the protective pads 28. After the rotation position reaches the limit, the rotation angle of the protective pads 28 is locked by the first electric drive rotating shaft 11 and the aluminum ingot is grabbed. After the aluminum ingot is completely lifted, the L-shaped support plate 19 is controlled to rotate by the second electric drive rotating shaft 18, so that the L-shaped support plate 19 bears the force on the bottom of the aluminum ingot. After the L-shaped support plate 19 rotates to fit the protective pads 28, the threaded rod 27 rotates out from inside the rotating disc 13 and the cover plate 23 and is threadedly connected to the threaded hole 22, thereby better locking the using position of the L-shaped support plate 19 and better limiting and protecting the grasping of the aluminum ingot.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
