Abstract
The invention relates to the technical field of self-piercing riveting processes, in particular to an assistant positioning method for self-piercing riveting. An assistant positioning mold is manufactured according to a self-piercing riveting device and is composed by a back plate and a bottom plate which are perpendicularly connected to form an L shape. A positioning hole with the external diameter the same as that of a lower riveting mold of the self-piercing riveting device, the position of the positioning hole is determined by the size of a test piece needing riveting, the thickness of the bottom plate is the same as the height of the lower riveting mold, and a middle scale is vertically arranged on the back plate and coincides with the circle center of the positioning hole. First, the positioning hole of the assistant positioning mold is sleeved on the lower riveting mold of the self-piercing riveting device, the back plate is kept vertically upward, then the test piece is placed on the bottom plate of the assistant positioning mold and close to the back plate, the position needing riveting of the test piece is directed at the middle scale, and then the assistant positioning for the self-piercing riveting is achieved. A self-piercing riveting joint can be accurately centered in a very short time, and not only is the self-piercing riveting quality of the self-piercing riveting joint ensured, but also the manufacturing efficiency is promoted.
Description
Technical field
The present invention relates to self-piercing riveting technology field, particularly a kind of assisted location method of self-piercing riveting.
Background technology
Self-punching riveting technology is a kind of new light sheet material interconnection technique fast-developing in recent years, be specially adapted to the difficult welded blank such as light-alloy, composite, the optimal substitute technology of conventional point welding technology, increasingly extensive in the application in automobile and aircraft manufacturing field at present.In sheet material self-piercing riveting process, jointly carry out METHOD FOR LARGE DEFORMATION ELASTOPLASTIC by self-punching rivet and sheet material, form mechanical internal lock, realize firmly being mechanically connected.But the self-piercing riveting equipment used at present does not have positioner at lower rivet model place, must rule of thumb estimate centering carry out self-piercing riveting by operating personnel.This method is both time-consuming, be difficult to accurate centering again, therefore self-piercing riveting quality and production efficiency can not be guaranteed.
Summary of the invention
The object of this invention is to provide a kind of self-piercing riveting assisted location method, to solve centering difficulty in self-piercing riveting process, the problem of self-piercing riveting quality and production efficiency can not be ensured.
Self-piercing riveting assisted location method of the present invention is:
(1) as shown in Figure 3, auxiliary positioning mould is prepared according to self-piercing riveting equipment, auxiliary positioning mould forms " L " type by backboard connected vertically and base plate, base plate there is the locating hole 1 identical with self-piercing riveting equipment lower rivet model 2 external diameter, the size of the test specimen that the position of locating hole 1 is riveted as required is determined, the thickness of base plate is identical with the height of lower rivet model 2, backboard is vertically provided with graduation mark 3 in overlapping with locating hole 1 center of circle; As shown in Fig. 1 ~ 2.
(2) locating hole 1 of the auxiliary positioning mould first step 1 prepared is enclosed within the lower rivet model 2 of self-piercing riveting equipment, keep backboard vertically upward, then on base plate test specimen being placed on auxiliary positioning mould and near backboard, and test specimen is needed graduation mark 3 in the position alignment of riveted joint, namely achieve the auxiliary positioning of self-piercing riveting.As shown in Figure 4.
The drift of self-piercing riveting equipment, behind realization location, is aimed at the position that test specimen needs riveted joint, is riveted by the present invention.
The invention has the advantages that and use test specimen self-piercing riveting auxiliary locator, make the test specimen of any width can within very short time accurate centering, both ensured test specimen self-piercing riveting quality, turn improved production efficiency, by the extensive use promoting sheet material self-punching riveting technology at each field of industrial production.
