Abstract
The utility model belongs to the field of automobile riveting devices, and relates to riveting devices which are provided with riveted rivets in the shape similar to a segment and arranged on automobile seats, in particular to a similar-segment-shaped rivet head riveting structure. The rivet head riveting structure is composed of a radial riveting similar-segment-shaped riveting rivet head and a radial riveting machine, and comprises a fine adjustment screw sleeve, an oil filling port, a lubricating face, a safety cover, a spherical seat, a spring, a rivet head, a main shaft and a ball bearing, and the fine adjustment screw sleeve is arranged outside the main shaft. The oil filling port is formed in the upper portion of the lubricating face. The safety cover is arranged on the lower portion of the fine adjustment screw sleeve. The ball bearing is arranged on the upper portion of the spherical seat. The spring is arranged in the safety cover. The rivet head is arranged on the lower portion of the safety cover. Compared with a traditional semicircular rivet head, riveting noise is low in the riveting process, forming speed is high, surface quality after riveting is good, and the shape after riveting can bear larger shearing force.
Description
Technical field
The utility model belongs to automobile riveting set field, particularly relates to the riveting set that is shaped as class segment-shaped after the rivet riveting on automotive seat.
Background technology
In car load assembling process, after automotive seat, arrange the quality of assembly quality between back part and vehicle body, will directly have influence on stability and the security of automobile, the exact connect ion of these two parts is critical function sexual factors of guaranteeing back seat intensity and comfortableness.Rear row's backrest and vehicle body mounting portion majority in the middle of prior art all adopt chain connection, and the processing technology of hinge is generally and revolves riveting, revolve riveting substantially all to select simple platypelloid type die or semi-circular die, a little less than the former carries shearing force ability, it is long that the latter rivets man-hour, and friction noise is large.Therefore after the automotive seat in the middle of prior art, arrange assembling shaping speed between back part and vehicle body slow, riveting rear surface poor quality, after riveting, shape carrying shearing force is little.
In sum, for the problem existing in the middle of prior art, this area is needed badly and is wanted a kind of new technical scheme to solve these problems.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of riveting knot structure class segment-shaped that revolves for two of automotive seats and multiple metalworks to rivet die structure.
Class segment-shaped die riveted structure, it is characterized in that: this die riveted structure is made up of radial rivet class segment-shaped riveted joint die and radial riveting machine, comprise fine setting swivel nut, tank filler sleeve, lubricated face, safety guard, spheric seating, spring, die, main shaft, ball bearing, described fine setting swivel nut is installed on the outside of main shaft; Described tank filler sleeve be arranged at lubricated face above; Described safety guard is positioned at the bottom of fine setting swivel nut; Described ball bearing be installed on spheric seating above; Described spring fitting is in the inside of safety guard; Described die is positioned at the bottom of safety guard.
On described die, be provided with Baltimore groove.
The inner surface of the Baltimore groove on described die is processed with three lobe spiral laminations; This Baltimore groove inner surface is furnished with the round pool of diameter=2, and this round pool is evenly arranged.
Can bring following beneficial effect by above-mentioned design the utility model: the utility model is with respect to traditional semicircle die, rivet noise little when its riveted joint, shaping speed is fast, and riveting rear surface quality is good, and after riveting, shape is anti-can carry larger shearing force.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is class segment-shaped die riveted structure schematic diagram of the present utility model.
Fig. 2 is riveted joint process work schematic diagram.
Fig. 3 is die design size schematic diagram.
Fig. 4 is die partial enlarged drawing.
Fig. 5 is die right view one.
Fig. 6 is die right view two.
The specific embodiment
A kind segment-shaped die riveted structure as shown in the figure, it is characterized in that: it is made up of radial rivet class segment-shaped riveted joint die and radial riveting machine, its material selection mould steel of radial rivet class segment-shaped riveted joint die (CR12MoV, W18Cr4V), press die design size processing (as Fig. 3), carry out Quenching Treatment (HRC58～62), finally go up grinding machine and be ground to design size, surface roughness is reached more than 0.8.As shown in Figure 2 the die processing by design size is assembled in radial riveting machine, in the riveting machine course of work, motor passes motion to main shaft by shaft coupling, main shaft passes motion to spheric motion pair by small teeth difference planetary mechanism, hydraulic system driven plunger is exerted pressure downwards together with spherical pair simultaneously, in the time that die touches rivet, die carries out fricton-tight spreading by plum blossom movement locus to rivet around rivet center line (being spindle centerline), and rivet riveting is become to class segment-shaped and completes riveting work.It is higher to the dimension D required precision in die design size (Fig. 1) for radial riveting machine operation principle, therefore need strict guarantee in process.
According to radial rivet class segment-shaped die riveted structure claimed in claim 1, it is characterized in that: radial rivet class segment-shaped riveted joint die have with rivet riveting after the similar Baltimore groove of shape (as Fig. 4), for meeting die and in riveted joint process, rivet being carried out to fricton-tight spreading by the rivet of riveting.
According to radial rivet class segment-shaped riveted joint die structure claimed in claim 1, it is characterized in that: the Baltimore groove inner surface of radial rivet class segment-shaped riveted joint die is processed three lobe class spiral laminations and is evenly distributed minor diameter (2) round pool (as Fig. 5,6), in the time of riveted joint, this texture contributes to the metal flow of rivet in riveted joint process, further guarantee die and in riveted joint process, rivet carried out to fricton-tight spreading by the rivet of riveting, relatively reduce and rivet man-hour, while guaranteeing to rivet, do not send larger noise.
Claims (3)
1. class segment-shaped die riveted structure, it is characterized in that: this die riveted structure is made up of radial rivet class segment-shaped riveted joint die and radial riveting machine, comprise fine setting swivel nut (1), tank filler sleeve (2), lubricated face (3), safety guard (4), spheric seating (5), spring (6), die (7), main shaft (8), ball bearing (9), described fine setting swivel nut (1) is installed on the outside of main shaft (8); Described tank filler sleeve (2) be arranged at lubricated face (3) above; Described safety guard (4) is positioned at the bottom of fine setting swivel nut (1); Described ball bearing (9) be installed on spheric seating (5) above; Described spring (6) is installed on the inside of safety guard (4); Described die (7) is positioned at the bottom of safety guard (4).
