Reverse radial gate trunnion shaft sleeve inner hole key groove machining device and machining method

Abstract

The invention discloses a reverse radial gate trunnion shaft sleeve inner hole key groove machining device and machining method. A common shaping machine is adopted, and a special trolley type workbench, a lengthened cutter bar and a telescopic connecting device are designed to be matched with the common shaping machine to complete machining of reverse radial gate left and right trunnion shaft sleeve inner hole key grooves. The trolley type workbench is used for supporting and clamping a reverse radial gate large component, the supporting and clamping problem of the large component is solved, the transverse movement friction coefficient of the trolley type workbench is small, and the load generated when the workbench of the shaping machine is transversely fed is reduced; and the lengthened cutter bar is adopted, the machining requirement for the small diameter of an inner hole is met, and the problems that the diameter of the inner hole is small, and a cutter difficultly enters the inner hole for machining are solved. The problems that large-scale special machining equipment is limited, the diameter of the inner hole is small, and the cutter is difficult to enter the inner hole for machining are solved. The device is simple to operate and convenient to use, optimizes the machining technology, reduces the machining difficulty, saves the machining cost, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of ship lock hinges, in particular to a device and method for processing key grooves in inner holes of support hinge sleeves of reverse arc doors. Background technique [0002] In the ship lock hub project, the reverse arc door is a kind of working valve used to fill or drain the lock chamber. It is arranged in the water-filled corridors of the upper lock head and the lower lock head, and is opened or closed by controlling the reverse arc door. , to complete the water filling or drainage to the lock chamber, and realize the adjustment of the water level of the lock chamber to meet the intercommunication needs of upstream and downstream ships. When the reverse arc door is opened or closed, the hinge shaft rotates in the hinge seat, and the hinge shaft and the hinge sleeve are driven by a flat key connection (the hinge sleeve of the reverse arc door, the support arm structure, the panel The structure is welde...

AI Technical Summary

Problems solved by technology

Due to the large size of the reverse arc door, it is difficult to process the keyway in the inner hole of the hinge sleeve, and it is difficult to complete the processing with conventional equipment

[0003] In the prior art, the processing methods of the inner hole keyway are usually planing, milling, inserting, etc. The workpieces are mostly medium and small-sized products, which can be clamped on the workbench of the processing equipment to complete the keyway processing. For the inner hole keyway processing of large components, the Very difficult (the reverse arc door in this application is a super-large component), not only requires large-scale special processing equipment, but also due to the small diameter of the inner hole, it is difficult for the tool to enter the inner hole for processing, and the processing technology is complicated
