Embodiment Construction

[0018] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the present invention is made up of suspension hook 1, return spring 2, cover plate 3, positioning cylinder 4, hook plate 5, nut 6, bolt 8 and cylindrical pin 7 etc. made up of round steel, and one end of suspension hook 1 is The other end is made into a threaded structure, and the hook 1 of the lifting part is connected with the lifting device to provide lifting power. The positioning cylinder 4 has an eccentric through hole, a threaded hole and an arc through groove 9. The hook 1 passes through the eccentric through hole of the positioning cylinder 4 and is connected with the hook plate 5 through a nut 6. The positioning cylinder 4 cooperates with the step hole of the workpiece to realize positioning , the outer diameter of the positioning cylinder 4 is 3-5mm smaller than the inner diameter of the workpiece center hole, the height of the positioning cylinder 4 is gr...

Abstract

The utility model relates to a hoisting tool for hoisting workpieces with cylindrical stepped holes, which is used for hoisting smooth cylindrical workpieces. The positioning cylinder has an eccentric through hole, a threaded hole and an arc through groove. The hook passes through the eccentric through hole of the positioning cylinder and is connected to the hook plate through a nut. The positioning cylinder cooperates with the step hole of the workpiece to achieve positioning; the hook plate has an eccentric hole , and stuck in the circular arc groove of the positioning cylinder; the cover plate used to fix the positioning cylinder and the return spring is set on the hook, and fixed on the upper surface of the positioning cylinder by bolts; the return spring is positioned on the suspension by the cylindrical pin on the hook. The invention can accurately control the lifting point of the smooth cylindrical workpiece. After lifting, the workpiece does not slip, which is safe and reliable; after lifting the workpiece, the workpiece can be kept in a horizontal state. The quality; easy to operate, can meet the hoisting of various cylindrical workpieces.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a hoisting tool used for hoisting a workpiece with a smooth outer surface and a stepped hole inside. Background technique [0002] When assembling the automobile axle assembly, many cylindrical workpieces are assembled on the assembly. During the manufacture of cylindrical workpieces, they need to be lifted smoothly. Because of its relatively smooth shape and structure, it is not easy to lift it with a sling, and it is more likely to use a hook to hook the inner hole of the cylindrical workpiece and then lift it. But this simple and easy suspension hook just hangs workpiece, can not guarantee to be able to lift smoothly, and workpiece slips easily from lifting hole in the process of lifting, there is bigger potential safety hazard. At the same time, it is easy to deflect when lifting and transporting cylindrical workpieces with ordinary hooks, which makes it im...
