The utility model discloses be adjusted into the upper end of body the high reasonable in design of little cylindrical section, little cylindrical section, outer disc and the frame welded fastening of little cylindrical section during the welding, and this little cylindrical section can block the welding slag effectively, prevents that the welding slag from getting into in the internal thread hole to avoid damaging the internal thread hole, just so can guarantee smoothly with in the wrong screw hole that enters of screw rod.
Description
Technical field
The utility model relates to the parts on bumper, specifically, particularly relates to the vehicle frame jointing on a kind of bumper.
Background technology
Vehicle frame jointing is a vitals on bumper, and as shown in Figure 1, body 1 manufactured materials of existing vehicle frame jointing is 20 steel, and this body 1 is rotary structure, and its whole height H is 13.5mm.The center of body 1 has the internal thread hole 1a of a M12 vertically, and this internal thread hole 1a is through hole, and internal thread hole 1a is used for connecting screw rod.
Described body 1 underrun chamfered edge section 1b is connected with cylindrical section 1c lower end, and the diameter of this cylindrical section is 36mm; The upper end of cylindrical section 1c is connected with conical section 1e lower end by arc section 1d, the junction smooth transition of arc section 1d and cylindrical section 1c, conical section 1e; Large little under described conical section 1e, the upper end of this conical section 1e is directly connected with the end face of body 1.
During use, end face and the Frame Welding of body 1 are fixed, thus are fixed on vehicle frame by the utility model, and in internal thread hole 1a connecting screw rod.In the fabrication process, we find that existing vehicle frame jointing exists following defect:
Because the upper end of circular conical surface 1a is directly connected with body 1 end face, when so just causing welding, welding slag easily falls in internal thread hole 1a, thus damages internal thread hole 1a, can cause so being again screwed into screw rod, and then cannot install, be badly in need of solving above-mentioned technical barrier for this reason.
Utility model content
Technical problem to be solved in the utility model is to provide the jointing of the vehicle frame on a kind of bumper, and during for preventing from welding, welding slag is fallen in internal thread hole.
The technical solution of the utility model is as follows: the vehicle frame jointing on a kind of bumper, the body (1) of this joint is rotary structure, an internal thread hole (1a) is had vertically in the center of body, this internal thread hole is through hole, and this internal thread hole (1a) is for connecting screw rod; Described body (1) underrun chamfered edge section (1b) is connected with cylindrical section (1c) lower end, cylindrical section (1c) upper end is connected with conical section (1e) lower end by arc section (1d), and the equal smooth transition in junction of arc section (1d) and cylindrical section (1c), conical section (1e); It is characterized in that: large little under described conical section (1e), the upper end of this conical section is directly connected with roundlet shell of column (1f) lower end, and the upper end of roundlet shell of column (1f) is directly connected with body (1) end face, and the height (h) of roundlet shell of column (1f) is 0.6-1mm.
Adopt above technical scheme, the upper end of body (1) is adjusted to roundlet shell of column (1f) by the utility model, and the height (h) of this roundlet shell of column (1f) is 0.6-1mm.During welding, periphery and the Frame Welding of this roundlet shell of column (1f) are fixed, and subside after the fusing of the periphery of this roundlet shell of column (1f), this makes it possible to effectively block welding slag, thus prevent welding slag from entering in internal thread hole (1a), and then avoid damaging internal thread hole (1a), so just can ensure successfully screw rod to be screwed in internal thread hole (1a).
As optimal design, the height (h) of described roundlet shell of column (1f) is designed to 0.8mm by spy, and the diameter of this roundlet shell of column (1f) is 14mm.
Adopt said structure, the height (h) of roundlet shell of column (1f) is preferably 0.8mm, the numerical value of this height (h) is moderate, can prevent can not stopping welding slag completely because of highly too small like this falls in internal thread hole (1a), can avoid again increasing whole height because of highly excessive.
As preferably, the manufactured materials of described body (1) is 20 steel, and its whole height (H) is 13.5mm.
In the present case, the specification of described internal thread hole (1a) is M12mm, and the diameter of described cylindrical section (1c) is 36mm.
Beneficial effect: the upper end of body is adjusted to roundlet shell of column by the utility model, the height of this roundlet shell of column is reasonable in design; During welding, the periphery of roundlet shell of column and Frame Welding are fixed, and this roundlet shell of column can block welding slag effectively, prevent welding slag from entering in internal thread hole, thus avoid damaging internal thread hole, so just can ensure successfully screw rod to be screwed in internal thread hole, and then the defect of conventional art is just overcome well by little change, there is good practicality.
