Abstract
The utility model relates to a novel pressure bushing tooling assembly which comprises a rivet, an oscillating arm upper plate, a ball pin handle part and an oscillating arm lower plate. The ball pin handle part is assembled in an opening of the oscillating arm upper plate and the oscillating arm lower plate; the rivet penetrates through the middle parts of the oscillating arm upper plate, the oscillating arm lower plate and the ball pin handle part, and the head part of the rivet is placed in a tapered hole of a rivet pre-pressing head; and the ball pin handle part is a casting, and a mounting hole for mounting the rivet is arranged inside the ball pin handle part and is conical. The novel pressure bushing tooling assembly has the advantages of high efficiency, high connecting strength, simplicity in processing, stable quality, small investment, wide use scope (the novel pressure bushing tooling assembly can also be used when a non-tapered hole part is riveted) and the like and can be more fully and widely applied to the auto industry in which the riveting process is gradually popular.
Description
Technical field
The utility model relates to the servicing unit field in early stage of riveted joint, particularly a kind of novel pressure lining frock assembly that is applied to the part assembling implementation procedure of swing arm and other same process under the automobile that riveted joint connects.
Background technology
Along with the fast development and the domestic universal gradually and attention that rivet technology is used of external riveting technology, high efficiency, high-intensity fastening technology more and more are widely used in the auto parts and components industry.Existing riveting set structure is: after ball pin handle portion 4 is assembled in the swing arm with rivet 2; Directly riveted joint; And such shape that only can change the rivet exposed parts merely; Effect after riveted joint is accomplished is axially to produce certain pretightning force, and rivet radially has only the distortion of minute quantity, and amplitude of deformation can't be filled up the gap in the bellmouth far away; The swing arm part that so machines is under the condition that car load uses; After a period of time; Wearing and tearing or detrusion will take place in rivet, cause the ball pin loosening, when certain severity is driven, abnormal sound will take place; Possibly cause the rivet fracture for a long time, thereby the loosening risk that causes abnormal sound of very high generation is arranged.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned existence; And a kind of part assembling implementation procedure that is applied to swing arm and other same process under the automobile that riveted joint connects is provided; Can better guarantee swing arm ball pin bonding strength and connective stability, better guarantee the novel pressure lining frock assembly of complete vehicle quality and user satisfaction.
The purpose of the utility model is accomplished through following technical scheme, and it comprises rivet, swing arm upper plate, ball pin handle portion, swing arm lower plate, and opening of described swing arm upper plate and swing arm lower plate is equipped with a ball pin handle portion in the shelves; Described rivet is through swing arm upper plate, swing arm lower plate and the ball pin handle three's of portion centre, and the head of rivet places in the bellmouth of rivet precompressed pressure head.
As preferably, described ball pin handle portion is a foundry goods, its inside be provided with one be used to install rivet installing hole, this installing hole is taper.
As preferably, described rivet precompressed pressure head contacts with the swing arm upper plate after through the effect of the cylinder application of force.
The beneficial effect of the utility model is: 1, as this security part of swing arm, this novel pressure lining frock assembly can effectively guarantee part strength, promotes the product safety performance; 2, frock making is simple, realize very easily voluntarily, and cost of investment is lower, is of wide application.
Description of drawings
Fig. 1 is the status architecture sketch map before the utility model riveted joint.
Fig. 2 is the status architecture sketch map after the utility model riveted joint.
Fig. 3 is that the utility model riveted joint back rivet exposes the morphosis sketch map.
Label in the accompanying drawing is respectively: 1, rivet precompressed pressure head, 2, rivet, 3, the swing arm upper plate, 4, ball pin handle portion, 5, the swing arm lower plate, 11, bellmouth, 41, installing hole.
The specific embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: shown in accompanying drawing 1, comprise rivet 2, swing arm upper plate 3, ball pin handle portion 4, swing arm lower plate 5, described swing arm upper plate 3 is equipped with a ball pin handle portion 4 with opening of swing arm lower plate 5 in the shelves; Described rivet 2 is through swing arm upper plate 3, swing arm lower plate 5 and 4 threes' of ball pin handle portion centre, and the head of rivet 2 places in the bellmouth 11 of rivet precompressed pressure head 1.Described ball pin handle portion 4 is a foundry goods, its inside be provided with one be used to install rivet 2 installing hole 41, this installing hole 41 is taper (because technology is limit, the certain pattern draft of needs is the taper installing hole so embody).
Described rivet precompressed pressure head 1 contact with swing arm upper plate 3 after through cylinder or the downward application of force effect of oil cylinder (shown in accompanying drawing 2).The demand of this cylinder or oil cylinder is general small-sized hydraulic machine (concrete tonnage is decided with reference to rivet bar and yield strength); Take all factors into consideration according to the required precompressed deflection of rivet, rivet surplus, rivet diameter and to carry out 1 processing of rivet precompressed pressure head and be mounted on the hydraulic press; Positioning fixture is made according to the product actual conditions and is got final product, and the axiality of rivet 2 and rivet precompressed pressure head 1 need guarantee.
The operation principle of the utility model (like accompanying drawing 1,2, shown in 3):
Swing arm assembling good shot pin, rivet 2 are placed on the special-purpose positioning fixture and clamping; Rivet precompressed pressure head 1 applies active force downwards under cylinder or oil cylinder effect, riveted joint surplus that the size of the bellmouth 11 on the rivet precompressed pressure head 1 exposes according to rivet 2 (volume V1) and rivet 2 insert bellmouth 11 post gap volume V2 and calculate: bellmouth volume=V1-V2.
When rivet precompressed pressure head 1 is depressed and during until contact swing arm upper plate 3, rivet 2 fully is out of shape (material flows downward and reaches in the bellmouth 11 and has gap location), obtains certain radial stress until filling up whole bellmouth 11.
And then axially rivet, obtain enough axial pre tightening forces, realize the fastening purpose of swing arm upper plate 3, ball pin handle portion 4 and swing arm lower plate 5.
Except that the foregoing description, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
