Abstract
The utility model discloses a reinforcing ring for an automobile skylight. The reinforcing ring comprises a reinforcing ring body of the skylight. A bolt connected with the skylight is in projection welding on the reinforcing ring body of the skylight. The conventional projection welding positioning bottom hole is improved, the diameter of the positioning bottom hole is changed from original (M+0.5) mm to (M+0.1) mm, and the tolerance is changed from original 0.2 mm to 0.1 mm, wherein M is the nominal diameter of the bolt, so that the gap between the projection welding positioning bottom hole and the projection welding positioning bolt is reduced, and meanwhile, the tolerance range is further reduced, the projection welding precision is enhanced, the position precision and verticality of the projection welding bolt are improved, and the position of the bolt is ensured. The reinforcing ring of the skylight is in positioning connection with the skylight conveniently, so that the installing and positioning precision of the skylight is ensured, the installing quality is improved and the service performance of the skylight is improved.
Description
Technical field
The utility model relates to a kind of reinforcing ring for automobile skylight, particularly a kind of reinforcing ring for automobile skylight with the bearing surface projection welding bolt.
Background technology
Vehicle dormer window mainly plays ventilation, daylighting and effect attractive in appearance, and vehicle dormer window generally is comprised of brace panel and skylight body.The skylight brace panel is weldingly fixed on the skylight opening place of covering for roofs, be provided with bolt on the brace panel of skylight, be provided with via hole on the body of skylight, skylight brace panel and skylight body are bolted, and the tail end of skylight body generally is connected by the mode of welding with covering for roofs.Bolt on the brace panel of general skylight is the bearing surface projection welding bolt, the weldability of bolt is required higher, the technique of the projection welding location bottom outlet that therefore matches with the bearing surface projection welding bolt also is one of the key factor that affects the weldability of the precision of projection welding and quality and bolt.Bolt projection welding face is necessary for the plane, and in order to reduce the projection welding electrode manufacturing cost, the aperture of general projection welding location bottom outlet is (M+0.5) mm, and dimension limit is 0.2mm, and M is the nominal diameter (Major Diam) of weld bolt.Because bolt and skylight ring stiffener belong to free-running fit, guarantee that according to the technological requirement needs position of bolt and squareness are so that the installation quality in assurance skylight.
Therefore, need to improve traditional technique, improve positional precision and the squareness of projection welding bolt, guarantee the position of bolt, further guarantee the installation accuracy of positioning in skylight.
The utility model content
In view of this, a kind of reinforcing ring for automobile skylight of the present utility model, traditional projection welding location bottom outlet is improved, change the location bottom diameter into (M+0.1) by original (M+0.5) mm standard, tolerance is improved to 0.1mm by original 0.2mm, M is the nominal diameter of bolt, dwindle the gap between projection welding location bottom outlet and the projection welding bolt, also dwindled dimension limit simultaneously, strengthened the precision of projection welding, improve positional precision and the squareness of projection welding bolt, guarantee the position of bolt, be convenient to being located by connecting of skylight ring stiffener and skylight, guarantee the installation accuracy of positioning in skylight, improve installation quality, thereby improve the in-use performance in skylight.
Reinforcing ring for automobile skylight of the present utility model is provided with at least 1 bolt that is connected with the skylight at skylight ring stiffener attachment face;
Further, described bolt is fixed in the bottom outlet of location by the bearing surface projection welding;
Further, the location bottom diameter is than the large 0.1-0.2mm of the diameter of bolt;
Further, the location bottom diameter is than the large 0.1mm of the diameter of bolt;
Further, the described diameter of bolt is 6mm;
Further, described projection welding location bottom outlet is 6.
The beneficial effects of the utility model: reinforcing ring for automobile skylight of the present utility model, traditional projection welding location bottom outlet is improved, change the location bottom diameter into (M+0.1) by original (M+0.5) mm standard, tolerance is improved to 0.1mm by original 0.2mm, M is the nominal diameter of bolt, dwindled the gap between projection welding location bottom outlet and the projection welding bolt, also dwindled simultaneously dimension limit, strengthen the precision of projection welding, improve positional precision and the squareness of projection welding bolt, guarantee the position of bolt, be convenient to being located by connecting of skylight ring stiffener and skylight, guarantee the installation accuracy of positioning in skylight, improve installation quality, thereby improve the in-use performance in skylight.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Fig. 1 is structural representation of the present utility model, and as shown in the figure: the reinforcing ring for automobile skylight of the present embodiment is provided with at least 1 bolt that is connected with the skylight at skylight ring stiffener attachment face 1.
In the present embodiment, described bolt is fixed in the bottom outlet of location by the bearing surface projection welding; Be convenient to the fixing of bolt, strengthen the fastness and the stability that connect.
In the present embodiment, described location bottom outlet 12 diameters are than the large 0.1-0.2mm of the diameter of bolt; Change the location bottom diameter into (M+0.1) by original (M+0.5) mm standard, tolerance is improved to 0.1mm by original 0.2mm, M is the diameter of bolt, dwindles the gap between location bottom outlet 12 and the projection welding bolt, strengthens the precision of bearing surface projection welding, guarantee the position of bolt, improve the squareness of the rear bolt of welding, be convenient to the installation in skylight ring stiffener and skylight, thereby improve the stickiness of integral installation, leak tightness improves the in-use performance in skylight.
In the present embodiment, described location bottom outlet 12 diameters are than the large 0.1mm of the diameter of bolt; Improve the precision of projection welding, strengthen the steadiness and the fastness that connect.
In the present embodiment, described projection welding location bottom outlet 12 is 6; Weld bolt on 6 location bottom outlets 12,6 bolts improve the accuracy of positioning of installing by the via hole that arranges on skylight nut captive joint, strengthen steadiness and the fastness of installing.
In the present embodiment, the described diameter of bolt is 6mm; The torque peak that can bear of M6 bolt is 5.5N.m, is comparatively desirable in the vehicle dormer window hold-down bolt, therefore, is the bolt of 6mm for diameter, is that 6.1mm is best with respect to diameter of its location bottom outlet.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
