Abstract
A ball head spring threaded column structurally comprises a spring, a bolt and a round head column. The spring is arranged in a hole formed in one end of the bolt. The round head column is arranged at the outer end of the spring inside the bolt. The round head portion of the round head column is exposed out of the bolt. The bolt is provided with a thread. A hexagonal socket, a straight line groove or an outer hexagonal socket are fixed on the tail portion of the bolt in a locking mode, and the fixed modes include a thread locking type, a press fit type and a rolling type. The ball head spring threaded column is accurate in automatic mechanical positioning in aviation, aerospace machinery, a clamping tool and a die, high in efficiency, solid and firm, strong in general using performance, simple in structure, convenient to use and quick in use.
Description
Technical field
The utility model relates to the mechanical device technology, relates in particular to bulb spring thread post, applies to machinery, anchor clamps, mould, automated machine equipment etc.
Background technique
Can provide in mechanical device, fixture, mould, the automated machine such as Aeronautics and Astronautics at home pressure and accurately the mechanical component of location also lack very much, and, at present in these industries, extensively usefulness all is inefficiency, locate inaccurate, in order to fill up the vacancy of this respect, need design a kind of simple, easy to make, to the mechanical devices such as Aeronautics and Astronautics, fixture, mould, automated machine, accurate positioning, efficient are high, the product of highly versatile.
Summary of the invention
The purpose of this utility model provides a kind of bulb spring thread post, its formation comprises bolt, spring, several parts of round head column, to be provided with spring in the hole of bolt, bolt inner spring outer end is provided with round head column, the round head column round end partly exposes bolt one end, bolt is provided with screw thread, the element that bulb spring thread post provides pressure and accurately locates by spring, its means of fixation has various, and being pressed into type, screw-threaded coupling type, roll-down type, bolt tail has straight groove, interior hexagonal, outer-hexagonal locking mode; Be pressed into the shell that has of type, shell is stainless steel or plastics, and the round end cylinder has long and short, standard type, and spring is divided into two kinds of underload or heavy dutys.
Round head column spheroid material has steel or stainless steel or nylon, acetal resin or the phenolic resin of sclerosis, and the use object requires with stressed material and decides, and such as softer metals, uses nylon material round end cylinder.This bulb spring thread post is applicable to the mechanical devices such as Aeronautics and Astronautics, fixture, mould, automated machine etc.
Adopt the beneficial effect of the technical program: at Aeronautics and Astronautics machinery, fixture, the accurate positioning of die automation machinery, high, solid firm, the highly versatile, simple in structure, easy to use, quick of efficient.
