Abstract
Description
Technical Field
[0001] The utility model relates to an end face processing tool, in particular to a processing tool for the external opening end face of a shackle, and belongs to the technical field of fetal membrane clamps. Background Art
[0002] The shackles used to connect ship anchor chains or mooring chains are generally divided into two types: bow shackles and straight shackles. Each shackle consists of a shackle body and a cross pin that crosses the shackle body's ball head. The dimensional accuracy and surface finish of the inner and outer openings of the shackle body's ball head must meet the requirements of the drawings. Currently, the two ends of the outer opening of the shackle ball head are generally machined using a slotting machine, or by placing the shackle flat on the milling machine table and machining it with an end mill. The disadvantages of slotting machines are low efficiency and poor surface finish on the workpiece, which often fails to meet the drawing requirements. While machining with an end mill can ensure the surface finish of the workpiece, it is less efficient. This is especially true when machining large-sized shackles (top diameter greater than 100 mm). The end mill protrudes too far from the tool holder, resulting in reduced rigidity and making machining impossible. Utility Model Content
[0003] The utility model aims to provide a shackle external opening end surface processing tool which has simple structure, low cost, high processing efficiency and can effectively ensure the processing quality of the shackle external opening.
[0004] The utility model is achieved through the following technical solutions:
[0005] A tool for processing the end face of the external opening of a shackle, comprising an inverted L-shaped right-angle plate, two upper pads, a lower pad and a pressure plate; positioning keys are respectively provided at both ends of the bottom of the horizontal side of the inverted L-shaped right-angle plate, the two upper pads are respectively fixed on the two ends of the vertical side of the inverted L-shaped right-angle plate, and the lower pad is fixed on one side of the horizontal side of the inverted L-shaped right-angle plate; the lower side of the top of the shackle is vertically supported on the lower pad, the top of the shackle rests on the upper pad at one end of the vertical side of the inverted L-shaped right-angle plate, the inner side of the shackle ball head is supported on the upper pad at the other end of the vertical side of the inverted L-shaped right-angle plate, and the two ends of the pressure plate are respectively pressed on the upper and lower sides of the top of the shackle, and locked by fasteners.
[0006] The purpose of the utility model can be further achieved by the following technical measures.
[0007] In the aforementioned tooling for processing the external end face of the shackle, the height of the upper pad at the other end of the vertical side of the inverted L-shaped right-angle plate matches the inner spacing of the shackle ball head.
[0008] The aforementioned shackle external open end surface processing tooling, wherein the two ends of the vertical side and one side of the horizontal side of the inverted L-shaped right-angle plate are respectively provided with positioning grooves, and the inner sides of the two upper pads and the inner sides of the lower pads are respectively fixed in the corresponding positioning grooves.

[0011] The utility model has a simple structure, low cost, and is easy to assemble and disassemble. The shackle can be placed vertically on the milling machine workbench, and the flying cutter disc can be used to quickly cut the external open end face of the shackle ball head. After processing one end face, the shackle can be flipped 180° to process the other end face. The shackle is clamped firmly and reliably, not only ensuring the surface finish of the external open end face of the shackle, but also effectively controlling its dimensional accuracy, reducing measurement time, and ensuring dimensional consistency during mass production. The utility model can replace workpieces at will, regardless of the size of the workpiece, and does not require adjustment of the milling machine scale. It has a wide range of uses, is suitable for mass production, and has high work efficiency.
