Description

Technical Field

[0001] The utility model relates to the technical field of pulley production, in particular to a device for realizing the flipping of pulley pieces. Background Art

[0002] In the production and manufacturing process of pulley pieces, due to the need of processing technology, it is often necessary to perform multiple flipping operations on the pulley pieces to complete processes such as double-sided processing and quality inspection. At present, mechanical flipping devices are generally used in production workshops to achieve this operation. However, the existing pulley piece flipping devices are cumbersome in the process of fixing pulley pieces, and workers need to adjust multiple clamping mechanisms to fix the pulley pieces; secondly, the disassembly process of pulley pieces is also complex, which not only increases the labor intensity of workers, but also restricts the improvement of production efficiency. Therefore, there are still disadvantages and deficiencies in the prior art. Summary of the Utility Model

[0016] The present utility model will be further described below with reference to the drawings.

[0017] As Figures 1-3 shown, the present utility model provides a device for realizing the flipping of pulley blades, including a horizontally arranged cross beam 1. Symmetrically arranged sliders 2 are slidably sleeved at both ends of the cross beam 1. A vertically arranged hanging bracket 3 is fixedly connected to the bottom surface of the slider 2. Chucks 4 are rotatably connected to the opposite surfaces of the two hanging brackets 3, and the two chucks 4 are symmetrically arranged. A first through hole 5 is vertically opened in the middle of the cross beam 1. A vertically arranged guide rod 6 is slidably connected in the first through hole 5. The guide rod 6 penetrates through the first through hole 5. A lifting ring 7 is fixedly connected to the top end of the guide rod 6. Inclined connecting rods 8 are hinged between the top of the guide rod 6 and the two sliders 2.

[0018] Specifically, this device is usually used in conjunction with a traveling crane. When in use, first, move the two chucks 4 to both sides of the groove of the pulley piece, and lift the lifting ring 7 by the traveling crane. At this time, the lifting ring 7 drives the guide rod 6 to move upward. The guide rod 6 drives the two sliders 2 to slide towards each other along the cross beam 1 through the two connecting rods 8. The two sliders 2 drive the two chucks 4 to move towards each other through the hanger 3. In this way, the chucks 4 can be clamped into the groove of the pulley piece and clamp the pulley piece, so as to facilitate the fixation of the pulley piece. Then, the pulley piece can be lifted by the device. Since the chuck 4 and the hanger 3 are rotatably connected, the worker can flip the pulley piece to complete processes such as double-sided processing and quality inspection of the pulley piece. Then, when the processing of the pulley piece is completed, lower the lifting ring 7 by the traveling crane, and then push the chuck 4 to move to both sides, so as to facilitate the removal of the pulley piece, and thus improve the production efficiency. In addition, by sliding the slider 2, the distance between the two chucks 4 can be adjusted, so as to be used to fix pulley pieces of different diameters and improve the applicability of the device.

[0019] In some embodiments, a second through hole 9 is horizontally formed on the hanger 3. A first bolt 10 is rotatably connected in the second through hole 9. The screw end of the first bolt 10 extends to the inner side of the hanger 3 and is connected to the chuck 4. The chuck 4 is rotatably connected to the hanger 3 through the first bolt 10 and the second through hole 9, so as to facilitate the flipping of the pulley piece.

[0020] In some embodiments, the first bolt 10 is threadedly connected to the chuck 4, so that the chuck 4 can be replaced to facilitate the adaptation to pulley pieces of different diameters, thereby improving the applicability of the device.

[0021] In some embodiments, the chuck 4 is crescent-shaped, so that the inner side of the chuck 4 can fit the groove on the outer edge of the pulley piece, enabling the pulley piece to be stably flipped, thereby improving the stability of the device.

[0022] In some embodiments, a horizontally arranged second bolt 11 is threadedly connected to the cross beam 1 corresponding to the first through hole 5. The screw end of the second bolt 11 extends into the first through hole 5. Specifically, when in use, after the chuck 4 clamps the pulley piece, by rotating the second bolt 11, the guide rod 6 can be tightened, so as to fix the guide rod 6, thereby ensuring that the chuck 4 does not loosen after clamping the pulley piece and improving the stability of the device.

[0023] In some embodiments, a limiting plate 12 is fixedly connected to the bottom end of the guide rod 6. By providing the limiting plate 12, the guide rod 6 can be limited, so as to prevent the guide rod 6 from slipping off, thereby improving the safety of the device.

[0024] In some embodiments, a self-locking wheel 13 is installed on the bottom surface of the hanging bracket 3. In this embodiment, a universal wheel with a self-locking function is installed on the bottom surface of the hanging bracket 3. Specifically, the universal wheel enables the device to move freely, thereby improving the mobility of the device.

[0025] The above embodiments can be combined with each other.

[0026] The above embodiments do not impose any formal restrictions on the shape, material, structure, etc. of the present invention. Any simple modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present invention all fall within the protection scope of the technical solution of the present invention.
