Abstract

The utility model discloses a kind of leaf chain rapid pipe joint, comprise screw body (1) and nut (2), described screw body (1) is fixed with linkage section (3), described linkage section (3) is the cavity of a upward opening, described nut (2) is hollow cylinder, the internal diameter of described nut (2) is identical with the external diameter of linkage section (3), and described linkage section (3) is connected for detachable with nut (2).The utility model has convenient disassembly, stable connection and advantage easily.

Description

A kind of leaf chain rapid pipe joint
Technical field
The utility model relates to rapid pipe joint, is specifically related to a kind of rapid pipe joint of leaf chain.
Background technique
It is use leaf chain that the headstock of current numerical control machine tool is connected with equilibrium block, and the existing joint of leaf chain utilizes pin-and-hole in the middle of chain, connects with high-strength screw.In numerical control machine tool using process at that time, the yielding or fracture in leaf chain joint during headstock high-speed motion and when having an impact.Wherein, leaf chain distortion words can cause the inconvenience of dismounting, and fracture can cause machine to quit work, and wastes time.The main cause of the problems referred to above is: there is multiple shear plane between leaf chain, and only have two shear planes in above-mentioned annexation, and its annexation is unstable, dismounting difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of convenient disassembly, stable connection and leaf chain rapid pipe joint easily.
For solving the problem, the utility model provides a kind of leaf chain rapid pipe joint, comprise screw body and nut, described screw body is fixed with linkage section, described linkage section is the cavity of a upward opening, described nut is hollow cylinder, and the internal diameter of described nut is identical with the external diameter of linkage section, and described linkage section and nut are detachable connection.
As further improvement of the utility model, cross-section and the leaf chain chain of described cavity are suitable.The cross-section of described cavity is consistent with leaf chain chain circumference is calabash shape.Described linkage section outer surface and nut internal surface are provided with screw thread, and described linkage section and nut are threaded connection.The external diameter of described linkage section is greater than the external diameter of screw body.Comprise thread section and positioning section in described nut, the internal diameter of described positioning section is less than thread section, and described positioning section is fixed at above thread section.The height of described linkage section: the height=1:1-3 of screw body.
The utility model compared with prior art, has the following advantages:
(1) simple, the stable connection of the utility model structure, only need unclamp nut when disassembly is desired, leaf chain can be taken out from the side, its connection is simply easy to use.Headstock high-speed motion, opposing impact can be coordinated and avoid deformation.Leaf chain is sheathed in the utility model, and its junction surface exceedes normal two of connecting, and stability increases, and is suitable for industrialized production.
(2), the cross-section of described cavity and leaf chain chain suitable, the profile of leaf chain chain is sugar coated haws shape, and the cross-section of cavity is also sugar coated haws shape, after nut and linkage section being tightened, its cavity and leaf chain chain fit tightly, and reach the effect of quick links.Described linkage section outer surface and nut internal surface are provided with screw thread, described linkage section and nut are threaded connection, and are threaded and ensure the stable connection of nut and linkage section further, thus reach integrally-built stability, and screwing operation is simple, easy to use.The external diameter of described linkage section is greater than the external diameter of screw body, ensures the stability of cavity, increases its shock resistance.Thread section and positioning section is comprised in described nut, the internal diameter of described positioning section is less than thread section, and described positioning section is fixed at above thread section, and thread section is for connecting linkage section, positioning section is used for the position after setscrew nut and linkage section compact siro spinning technology, ensures the normalization connected further.The aspect ratio of described linkage section and screw body is 1:1-3, and its ratio, under this ratio, can be saved manufacture cost and meet production requirement again, avoid deformation, and quick good connecting effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model leaf chain rapid pipe joint.
Fig. 2 is that the use of the utility model leaf chain rapid pipe joint is with reference to sectional view.
In figure: 1-screw body, 2-nut, 3-linkage section, 4-leaf chain chain, 5-thread section, 6-positioning section.
Embodiment
Below in conjunction with drawings and Examples the utility model is further explained explanation.
As depicted in figs. 1 and 2, a kind of leaf chain rapid pipe joint, comprise screw body 1 and nut 2, screw body 1 is fixed with linkage section 3, linkage section 3 is the cavity of a upward opening, nut 2 is hollow cylinder, and the internal diameter of nut 2 is identical with the external diameter of linkage section 3, and linkage section 3 is connected for detachable with nut 2.Cross-section and the leaf chain chain 4 of cavity are suitable.Linkage section 3 outer surface and nut internal surface are provided with screw thread, and linkage section 3 and nut 2 are threaded connection.The external diameter of linkage section 3 is greater than the external diameter of screw body 1.Comprise thread section 5 and positioning section 6 in nut 2, the internal diameter of positioning section 6 is less than thread section 5, and positioning section 6 is fixed at above thread section 5.Linkage section 3 is 1:1.5 with the aspect ratio of screw body 1.
Using method of the present utility model is, leaf chain chain 4 is put into linkage section 3 i.e. cavity, and then nut 2 and linkage section 3 are tightened by screw thread, now cavity and leaf chain chain 4 fit tightly, and complete connection.When needs maintain machinery or leaf chain chain 4 time, only nut need be unclamped, leaf chain chain can be taken out from the side.Of the present utility model easy for installation, structure is reliable, is suitable for industrialized production and uses.
