Description

Technical Field

[0001] The utility model relates to the technical field of casting hoisting, in particular to a multifunctional casting processing hoisting device. Background Art

[0002] In the prior art, in daily processing, the lifting of castings is an important part of the processing. Due to the different processes in the processing, it is often necessary to lift and flip the castings from one process to the next process. However, due to the heavy weight and large volume of the castings, it is usually necessary to design a lifting device for transportation and manually carry out the transportation. This method has many shortcomings.

[0003] 1. Traditional lifting operations use magnetic lifters and steel plate lifting clamps. The operation method is relatively cumbersome during lifting. The lifters usually come into direct contact with the surface of the casting. Since the surface of the workpiece has smoothness requirements, this method can easily touch the workpiece, causing scratches on the product and a decrease in yield.

[0004] 2. After the workpiece is processed, when it needs to be turned over for inspection at the next workstation, the workpiece needs to be placed on the workbench first, then turned over with the help of tools or manually, and then lifted again, which is time-consuming, labor-intensive and inefficient, and manual turning is prone to safety accidents.

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] Example

[0021] like Figure 1-3 As shown, a multifunctional casting processing lifting device includes a support device and a clamping device. The support device is composed of a lifting ring 1, a central lifting shaft 2, an upper end sleeve 14, and a lower end sleeve 5. The upper end sleeve 14 and the lower end sleeve 5 are mirror-symmetrically provided with a crankshaft arm 3 and an elastic branch rod 4 at both ends. The lower ends of the crankshaft arm 3 and the elastic branch rod 4 are provided with a clamping device connected thereto.

[0022] In this embodiment, the clamping device includes a rotating bearing 9 , one end of which is provided with a chuck shaft 7 and a rubber chuck 11 in sequence, and the rear end of the rotating bearing 9 away from the chuck shaft 7 is provided with an anti-movement cover plate 8 .

[0023] The chuck shaft 7 is close to one end of the rotating bearing 9, and the upper and lower ends thereof are symmetrically provided with a first positioning key 12 and a second positioning key 13. A cotter pin is provided on one side of the lifting ring 1, and the size of the cotter pin is 6 mm.

[0024] A suspension arm 15 is provided between the clamping device and the crankshaft suspension arm 3 and the elastic branch rod 4, and an elastic retaining ring is provided between the suspension arm 15 and the rotating bearing 9.
