Abstract
The invention relates to a combined rivet for precise riveting, belonging to the field of riveting technology. The combined rivet for precise riveting is characterized by consisting of a rivet rod anda rivet head, wherein the end part of the rivet rod is provided with a hole, and the rivet head is provided with a head corresponding to the position and the shape of the hole. The invention adopts two materials to respectively manufacture the rivet rod and the rivet head, and has the advantages of simple structure, convenient use and riveting deformation, high processing accuracy, location accuracy and riveting tightness, etc.
Description
Technical field
The invention belongs to the riveting technology field, particularly relate to a kind of combined rivet that is used for precise riveting.
Background technique
At present, riveted joint is the important connecting means in the machine-building, and particularly in motor was produced, the multilayer silicon steel sheet was combined by riveted joint, require between the silicon steel sheet riveted tight, and the relative position between the silicon steel sheet is accurate.Traditional clinching method as shown in Figure 4, wherein: integral rivet 1 is after carrying out silicon steel sheet 2 riveted joint, and integral rivet riveted joint back distortion is 3 inhomogeneous, riveted joint silicon steel sheet offsetting position 4 is obvious.
Adopt integral rivet tens of silicon steel sheets can be riveted together, but the problem that this riveted joint exists is: can influence the positional accuracy between the silicon steel sheet behind (1) integral rivet leading edge deformation, inhomogeneous deformation takes place in distortion 3 places, integral rivet riveted joint back as shown in Figure 1; (2) the irregular deformation meeting of integral rivet head influences the relative position and the tightness of riveted between the silicon steel sheet, silicon steel sheet offsetting position as shown in Figure 4.The problem that the tradition riveted joint exists can directly influence the quality of motor, can not satisfy the requirement that the high quality motor is produced.
Summary of the invention
The present invention provides a kind of combined rivet that is used for precise riveting for solving the technical problem that exists in the known technology.
The purpose of this invention is to provide a kind of have simple in structure, easy to use, Location accuracy is high and the combined rivet that is used for precise riveting of characteristics such as riveted joint tightness degree height.
Combined type rivet of the present invention is divided into rivet bar and rivet head two-part, and rivet bar adopts the higher metallic material of intensity to make, and rivet head adopts intensity reduction, plasticity preferred metal material to make.The length of rivet is divided into plurality of specifications according to the silicon steel sheet number of plies difference of riveted joint.The diameter of rivet and the riveted holes on the silicon steel sheet closely cooperate, to guarantee the Location accuracy between the silicon steel sheet.
The Connecting format of combined type rivet, there is the back taper hole front portion of rivet bar, and rivet head gos deep in the back taper hole.During riveted joint, rivet bar does not deform, only rivet head generation plastic deformation, and the procephalic flow of metal of rivet is full of the back taper hole, and the flow of metal at rear portion is with the silicon steel sheet riveted joint closely.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of combined rivet that is used for precise riveting is characterized in: rivet is made up of rivet bar and rivet head, and the rivet bar end has the hole, and rivet head has and hole site and the corresponding head of shape.
The present invention can also adopt following technological scheme:
The described combined rivet that is used for precise riveting is characterized in: the rivet bar end hole is a reverse taper hole, and rivet head should have conical head relatively.
The described combined rivet that is used for precise riveting is characterized in: the profile of rivet bar and rivet head is for circular.
The described combined rivet that is used for precise riveting is characterized in: rivet head is made by the good metallic material of plasticity.
Advantage and good effect that the present invention has are:
Be used for the combined rivet of precise riveting owing to adopted technological scheme of the present invention, compared with prior art have the following advantages:
1. combined rivet can adopt two kinds of materials to make rivet and rivet head respectively, and rivet can adopt the higher material of intensity, machining accuracy height; Rivet head is selected the good material of plasticity for use, is convenient to the riveted joint distortion.
2. Mao Jie Location accuracy height.Because the selected Strength of Metallic Materials height of rivet, can not deform during riveted joint, rivet diameter with closely cooperated by the hole on the riveting parts, guaranteed by the Location accuracy between the riveting parts, be out of shape the problem that is subjected to displacement by riveting parts that makes because of rivet when having eliminated common riveted joint.
3. Mao Jie tightness degree height, the high conformity of riveted joint.The length of rivet is according to the thickness decision of combination back multilayer silicon steel sheet, and length does not change during riveted joint, so the tightness degree of riveted joint is convenient to control, the high conformity of riveted joint.The rivet distortion is inhomogeneous when having eliminated common riveted joint, the riveted joint tightness degree inequality that causes, the shortcoming that the conformity of riveted joint is bad etc.
Description of drawings
Fig. 1 is a rivet bar structural representation of the present invention;
Fig. 2 is a rivet head structural representation of the present invention;
Fig. 3 is that the present invention rivets micromachine silicon steel sheet structural representation;
Fig. 4 is a prior art riveted joint micromachine silicon steel sheet structural representation.
Among the figure, the 1-rivet, the 2-silicon steel sheet is out of shape behind the 3-rivet, 4-silicon steel sheet offsetting position, 5-rivet bar, 6-rivet head, 7-back taper hole.
Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Consult accompanying drawing 1, Fig. 2, Fig. 3 and Fig. 4.
Embodiment 1
A kind of combined rivet that is used for precise riveting is made up of rivet bar 5 and rivet head 6, and rivet bar 5 ends have reverse taper hole 7, and rivet head 6 should have conical head relatively.The profile of rivet bar 5 and rivet head 6 is circular, and rivet head is made by plastic metal material.
The application of the combined rivet of embodiment's 1 precise riveting.Figure 3 shows that the riveted joint of micromachine silicon steel sheet 2, adopt the combined rivet riveted joint, rivet cooperates closely with hole on the silicon steel sheet, and rivet is indeformable during riveted joint, the Location accuracy height.Rivet head adopts the plasticity good metal to make, and is easy to make the metal of rivet head to be full of cone shape hole on the rivet during riveted joint, rivet and rivet head are connected as a single entity, and has realized the riveted joint of highi degree of accuracy, high reliability.
Claims (4)
