Abstract
The utility model relates to a riveting nut especially suitable for a closed thin-walled member, which comprises a countersunk head and a hollow rod part which is connected with the countersunk head into integration. The hollow rod part is a polished rod part and a screw thread part, namely, a riveting deformation part and a connective part. When the riveting is conducted, the riveting nut is inserted into the position needed tightening on the thin-walled member, corresponding match tools are selected and used, a screw nut is screwed tightly by using a twist measuring spanner, the torque is controlled, and the polished rod part suffers from force and is deformed to rivet the riveting nut and the thin-walled member into integration. The riveting nut has the advantages that the riveting nut and the thin-walled member can be lain on the same plane, and product reliability can be ensured.
Description
The utility model relates to a kind of Insert Nut, particularly a kind of Insert Nut that is used for being fastenedly connected thin-walled member.
The Insert Nut of prior art, its head are the tack protruding structure.Adopt such structure will cause thin-walled member to stagger mutually and not in same plane with the end face of Insert Nut, so making of the butting surface that is connected thin plate that the influence desire is connected with thin-walled member, during particularly for being connected thin plate and needing a plurality of screw-nut in some product, adopt existing Insert Nut to make troubles to flat panel production.In addition, as adopt existing Insert Nut structure, need polishing to remove tack after the installation, can destroy the prestressing force of riveted joint, influence the tensile strength of Insert Nut, thereby influence the reliability of Insert Nut.
The purpose of this utility model is to provide a kind of Insert Nut thin-walled member, that can guarantee reliability of products really that is particularly suitable for being used in.
The technical solution of the utility model is to provide a kind of Insert Nut, comprise a hollow stem portion, the top of this hollow stem portion is the polished rod part, the bottom is a helical thread portion, its characteristics be also to comprise one with hollow stem portion all-in-one-piece countersunk head, the polished rod part is 45 ° with the transition angle α of helical thread portion, and the countersunk head angle beta is 90 ° and 120 ° two kinds.
Aforesaid Insert Nut, wherein, described Insert Nut is made with low-carbon alloy steel.
The advantage of the utility model Insert Nut is: owing to adopted the countersunk head structure, so guaranteed that Insert Nut and thin-walled member are in same plane, so can not influence the installation of the thin plate that links to each other, and when riveted joint, can not influence inherent strength, thereby guarantee reliability of products really.
Below in conjunction with accompanying drawing by to the description of a preferred embodiment of the present utility model, to understand the purpose of this utility model, structural feature and advantage better.
Fig. 1 is the structural representation of the utility model Insert Nut;
Fig. 2 is the schematic representation of the utility model Insert Nut field riveting on thin-walled member.
See also Fig. 1, the utility model Insert Nut is hollow tubular substantially, is made by the high-quality low-carbon alloy steel.It comprises a countersunk head 1 and one and the hollow stem portion 2 that fuses of countersunk head 1.Wherein, the top of hollow stem portion 2 is polished rod part or riveted joint crushed element 21, and the bottom is helical thread portion or attachment portion 22.The polished rod part 21 of Insert Nut hollow stem portion is 45 ° with the transition angle α of helical thread portion 22, can guarantee that the initial position of the local deformation of Insert Nut hollow stem portion starts from the polished rod part, and can make the component number be about 50% of installation pulling force, thereby is convenient to control.The countersunk head angle beta of Insert Nut is preferably 90 ° and 120 °.
Describe the installation steps of the utility model Insert Nut in detail below in conjunction with Fig. 2.During riveted joint, Insert Nut is packed on the stay-bolt 5 of setting tool, put into manufactured thin-walled member 3, it is on the thin-walled member plane that stop-motion seat 4 is pressed on the Insert Nut plane, load onto cushion cover 6, with torque wrench rotating screw cap 7 and control torque, i.e. pretightening force Qp size, so that the hollow stem portion of Insert Nut protuberance is out of shape and formation crushed element 8, thereby Insert Nut and thin-walled member riveting are integral.
Claims (2)
1. Insert Nut, comprise a hollow stem portion 2, the top of this hollow stem portion 2 is polished rod part 21, the bottom is a helical thread portion 22, it is characterized in that, also comprise one with hollow stem portion 2 all-in-one-piece countersunk heads 1, polished rod part 21 is 45 ° with the transition angle α of helical thread portion 22, the countersunk head angle beta be 90 ° with 120 ° two kinds.
2. Insert Nut as claimed in claim 1 is characterized in that described Insert Nut is made with low-carbon alloy steel.
