Abstract
The utility model provides a combined structure of a sheet metal component and a self-tapping screw. The structure is characterized in that the fixation hole positioned on the sheet metal component is a flanged hole, the flanged hole has the tapered draft angle, and the opening of the flanged hole is pressed on the thread of the self-tapping screw. The combined structure adopts the flanged hole structure and allows the opening of the flanged hole with the tapered draft angle to be directly pressed on the thread of the self-tapping screw, thereby ensuring good self-locking property of the screw, preventing the damage of the thread and preventing the fixed parts from falling. The combined structure of the sheet metal component and the self-tapping screw is simple and easy to apply.
Description
Technical field
The utility model relates to the cooperating structure between self threading pin and the link, more particularly, especially be applied in automotive body in equipped the vehicle body sheet metal part and the cooperating structure between the self threading pin.
Background technique
The use of self threading pin is especially used the occasion of often not dismantling that is fastenedly connected for very common.Thread Forming TF is all having difference than regular screw threads aspect big footpath, path and the pitch, and relevant form has obtained standardization at present, referring to GB/T5280.
At present, use self threading pin to fix, at first directly fixedly opening fixed hole on the parent, utilize self threading pin to be connected with fixing parent fixed block again.In this Placement, fixedly the unlatching of fixed hole is less than Major Diam on the parent.In fact, this means of fixation is when screw is shot, and fixed hole is existing to be destroyed, and there is certain risk in the screw locking, especially under dynamical state, easily causes coming off of fixed block.For example, the annex that uses self threading pin to be fixed on the automotive body sheet metal part just has caducous problem.
The model utility content
The utility model is for avoiding above-mentioned existing in prior technology deficiency, the cooperating structure of a kind of vehicle body panel beating and self threading pin being provided, and is machine made solid and reliable to guarantee self threading pin.
The utility model technical solution problem adopts following technological scheme:
The characteristics of the cooperating structure of the utility model sheet metal part and self threading pin are that the fixed hole be positioned on the sheet metal part is set is the flange hole, and described flange hole has taper dials and touch the angle, and withhold on the screw thread of self threading pin in the aperture in flange hole.
The characteristics of the cooperating structure of the utility model sheet metal part and self threading pin also are:
The angle at taper molding angle that the flange hole is set is identical with the thread taper of self threading pin;
The flange height that the flange hole is set is not less than a pitch of self threading pin.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model adopts the structural type in flange hole because of it, dials the aperture in the flange hole of touching the angle and directly withholds on the screw thread of self threading pin to have taper, can guarantee that the screw self-locking property is good, and screw thread does not have breaking-up, fixed block does not have obscission.
2, the utility model is simple in structure, easy to implement.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure: 1 sheet metal part, 2 self threading pins, 3 fixed blocks.
Below by embodiment, the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment
Referring to Fig. 1, in the present embodiment, it is the flange hole that the fixed hole that is positioned on the sheet metal part 1 is set, the flange hole has taper molding angle, the angle [alpha] at taper molding angle is identical with the thread taper of self threading pin 2, and because of the standardized tapping screw angle of thread is 60 °, so drafting angle α is defined as 120 °.
The flange height in flange hole is not less than a pitch of self threading pin 2; Withhold on the screw thread of self threading pin 2 with the aperture that guarantees the flange hole.
In concrete the enforcement, the process of implementing to be fastenedly connected between fixed block 3, sheet metal part 1 and self threading pin 2 is: offer self threading pin and pass through the hole on fixed block 3, self threading pin is by the aperture D ≈ 1.1d0 in hole, d0 in the formula is the nominal diameter of self threading pin, can look in GB5280, the evaluation rounding is big integer; Flange height h on the sheet metal part 1 requires greater than a pitch, and pitch dimension GB5280 can look into;
In addition, setting the self threading pin fixed hole aperture that is open on the sheet metal part 1 is d, and panel beating thickness is H; The flange height is h, according to engineering experience, determines d and H relation such as following table:
Claims (3)
1. the cooperating structure of sheet metal part and self threading pin is characterized in that it is the flange hole that the fixed hole that is positioned on the sheet metal part (1) is set, and described flange hole has taper dials and touch the angle, and withhold on the screw thread of self threading pin (2) in the aperture in flange hole.
2. the cooperating structure of sheet metal part according to claim 1 and self threading pin is characterized in that the angle at taper molding angle in described flange hole is identical with the thread taper of described self threading pin (2).
3. the cooperating structure of sheet metal part according to claim 1 and self threading pin is characterized in that the flange height in described flange hole is not less than a pitch of described self threading pin (2).
