Abstract
The utility model provides a long lead screw which is characterized by consisting of two or more short lead screws, adhesive layers and connecting columns (connecting column heads), wherein each connecting column refers to a part two ends of which are respectively inserted into connecting holes of the two lead screws to connect the lead screws; each connecting column head refers to a part formed in a way that one end of the lead screw is processed to be column-shaped, inserted into the connecting hole of the other lead screw, and used for connecting the lead screws; and the adhesive layers are formed when adhesives on the connecting parts are cured. The long lead screw has the advantages that the adhesive layers and the connecting columns (connecting column heads) are used for connecting the short lead screws, the cured adhesive layers can play the roles in positioning and stress transfer; when the long lead screw is manufactured, screw holes or rivet holes do not need to be processed on the lead screws, screws or rivets are not used for fixing, the surfaces of the lead screws can be prevented from secondary damage, the dimension precision of the lead screws is improved, the length of the manufactured lead screw is not limited by the allowed processing length of manufacturing equipment or the length of materials, and the lead screw with any length can be manufactured according to the required dimension.
Description
Technical field
The utility model relates to a kind of novel long lead screw.
Background technique
Present long lead screw generally all be that integral body processes, but the length of leading screw often depends on the processing length and the raw-material length of manufacturing equipment.Large-scale long lead screw is that large size machine tool are difficult to substituted critical component, and its manufacture difficulty is very big.At present, the mode that produces large-scale long lead screw mainly comprises welding, is spirally connected, riveted joint etc.Above method is made large-scale long lead screw and must on leading screw, be welded, punch, and fixes with screw or rivet, and these all can cause secondary to destroy to the surface of leading screw, and the precision of leading screw is difficult to ensure, especially is difficult to ensure the accuracy of manufacturing requirement of ball screw.In addition, in links such as transportation, impaired distortion do not occur, often must make the leading screw bigger, so just caused unnecessary waste than user demand diameter dimension in order to guarantee long lead screw.It is reported, utilize existing technology, domestic manufacturing leading screw length at most also has only 14 meters, makes equipment and material that longer leading screw must be equipped with respective length, and this is to be difficult to realize basically.
Summary of the invention
The purpose of the utility model is the defective that overcomes existing technology, and a kind of long lead screw is provided, and has improved the dimensional accuracy of leading screw, can make the leading screw of any length according to required size.
The technological scheme that realizes the utility model purpose is: a kind of long lead screw, it is characterized in that connecting column cap by short leading screw, leading screw attachment hole, adhesive layer, attachment post or leading screw forms, and attachment post is connected through adhesive layer with the leading screw attachment hole; Or leading screw connection column cap is connected through adhesive layer with the leading screw attachment hole; Or two kinds of Placements are also used.Short leading screw can be two or many.Attachment post is column, and two ends can be inserted the leading screw attachment hole of two short leading screws respectively; Leading screw connects column cap and is meant that an end of short leading screw is processed to column, can insert the leading screw attachment hole of other short leading screw.
The advantage of the utility model is, utilizes adhesive layer to connect with attachment post (being connected column cap) between the short leading screw, the effect that the adhesive layer of curing has played the location and transmitted stress; No longer need on leading screw, process screw hole or rivet hole when making long lead screw; No longer need use screw or rivet to fix; The leading screw surface not being produced secondary destroys; Improved the dimensional accuracy of leading screw, but and the leading screw length of making no longer be subject to manufacturing equipment processing length and length of material, can make the leading screw of any length according to required size.
Description of drawings
Fig. 1 is one of structural representation of the utility model.
Fig. 2 be the utility model structural representation two.
Embodiment
Attachment post is connected through adhesive layer with the leading screw attachment hole; As shown in Figure 1; Leading screw 1a, leading screw 1b, leading screw 1c are the short leading screws that processes in advance, and leading screw attachment hole 2 places of the leading screw attachment hole 2 of attachment post 5 and leading screw 1a, the leading screw attachment hole 2 of leading screw 1b, leading screw 1c all scribble adhesive.The leading screw attachment hole 2 of leading screw 1a is connected with attachment post 5 with the leading screw attachment hole 2 of leading screw 1b, and another leading screw attachment hole 2 of leading screw 1b and the leading screw attachment hole 2 of leading screw 1c are connected with another attachment post 5.Attachment post 5 has been full of adhesive with the faying surface of leading screw attachment hole 2; Adhesive solidifies at normal temperatures or through heat treated; Formed adhesive layer 3; Last leading screw 1a, leading screw 1b, leading screw 1c, adhesive layer 3 and attachment post 5 have been formed long lead screw, according to said method can continue to splice the leading screw of random lengths.
The processed pillared leading screw of one end of leading screw connects column cap and is connected through adhesive layer with the leading screw attachment hole; As shown in Figure 2; Leading screw 1a, leading screw 1b, leading screw 1c are the short leading screws that processes in advance; The leading screw of leading screw 1b connects leading screw attachment hole 2 places of column cap 4 and leading screw 1a, and leading screw attachment hole 2 places that the leading screw of leading screw 1c connects column cap 4 and leading screw 1b all scribble adhesive, and the leading screw of leading screw 1b connects the leading screw attachment hole 2 that column cap 4 inserts leading screw 1a; The leading screw of leading screw 1c connects the leading screw attachment hole 2 that column cap 4 inserts leading screw 1b; Leading screw connection column cap 4 has been full of adhesive with the faying surface of leading screw attachment hole 2 like this, and adhesive solidifies at normal temperatures or through heat treated, has formed adhesive layer 3; Last leading screw 1a, leading screw 1b, leading screw 1c, adhesive layer 3, leading screw connect column cap 4 and have formed long lead screw, according to said method can continue to splice the leading screw of random lengths.
