Universal hoisting tool and method for front flange

Abstract

The invention discloses a universal hoisting tool and method for a front flange, and belongs to the field of machining. Comprising a supporting framework, a sliding chuck, a hoisting sliding block and a pull rod, the supporting framework comprises a guide rail, a lifting ring and a lifting vertical rod, and the lifting vertical rod is located at the center axis of the supporting framework. The inner ends of the plurality of guide rails are uniformly distributed on the outer peripheral surface of the lower end of the hoisting vertical rod in the circumferential direction; the lifting sliding block is coaxially arranged on the lifting vertical rod in a sleeving manner and can reciprocate up and down, and the lifting sliding block is axially limited by inserting a locking bolt into a lifting vertical rod limiting pin hole; the multiple sliding chucks sleeve the multiple guide rails in a one-to-one correspondence manner and can do reciprocating motion in the length direction of the guide rails; the axial movement of the lifting sliding block is converted into the horizontal reciprocating movement of the sliding chucks through the pull rods, so that the front flange is clamped and loosened by the sliding chucks. The tool has the advantages of being safe to use, accurate in clamping, rapid in hoisting and the like, and the geometric accuracy (especially roundness) of the thin-wall front flange product cannot be affected in the using process.

Description

Technical field [0001] The present invention belongs to the field of machining, and in particular, the present invention relates to a pre-flange universal lifting process and method. Background technique [0002] With the arrival of the digitization, my country's aviation, and space career has developed rapidly. In scientific research, a tapered thin-walled rebound (hereinafter referred to as: the former flange) parts have become more and more heavy. During the actual management process, in accordance with specifications and uses, it has achieved serialization management and group batch production, and the corresponding tooling fixture also achieves series, modular design management. Due to different series of forefrom ( figure 1 ) The product structure is extremely similar, and the size is large, the variety is wide, and the outer diameter is general. The above, the wall thickness is 2 to 20 mm, involving dozens of specifications. [0003] The former flange products belong to t...

Problems solved by technology

Larger specifications (more than 20kg per unit weight) require multiple people to lift them to the cart for transfer. After reaching the machine tool station, multiple people still need to be lifted to the machine tool workbench, which consumes a lot of physical strength for the operator and is prone to accidents. The surface of the product is bumped and damaged, and there is a certain safety risk
