Description
Technical Field
[0001] The utility model relates to the technical field of automobiles, in particular to a positioning device. Background Art
[0002] Hinges are important components for opening car doors. They affect the clearance and surface difference around the door and the quality of door opening and closing. Therefore, quality monitoring of door hinges is crucial.
[0003] When testing the contour of the hinge's mounting surface, the industry typically uses a datum target to limit the part's rotational freedom. A corresponding fixed datum block is placed on the inspection fixture, and the hinge is rotated to the fixed datum block and clamped securely before testing the contour deviation of the hinge's mounting surface. This results in the existing hinge's positioning datum limiting angle not matching the required limiting angle of the hinge during actual vehicle assembly. Consequently, part measurement results fail to truly reflect the impact of deviations in the assembly state, failing to effectively identify out-of-tolerance parts and requiring frequent on-site repairs and adjustments. Therefore, overcoming these technical problems and drawbacks has become a key issue that needs to be addressed. Utility Model Content

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0025] like Figure 1-2 As shown, in one embodiment, the utility model provides a positioning device for rotational positioning of a hinge structure 1, including a fixing part 2, an orienting structure 3, a positioning structure 4 and a fixing mechanism; the hinge structure 1 includes a hinge fixing part 11 and a hinge movable part 12, the hinge movable part 12 is rotatably connected to the hinge fixing part 11, the fixing part 2 is used to position the hinge fixing part 11, and a plurality of positioning reference blocks 42 are provided on the positioning structure 4, and the plurality of positioning reference blocks 42 are located on a reference plane parallel to the designed installation surface of the hinge movable part 12. When the hinge movable part 12 rotates to the designed installation surface relative to the hinge fixing part 11, the hinge movable part 12 abuts against the positioning reference block 42 of the positioning structure 4, and the fixing mechanism is used to fix the hinge movable part 12 on the positioning reference block 42. The positioning structure 4 can be slidably set on the orienting structure 3 in a direction perpendicular to the reference plane.
[0026] The utility model sets an orientation structure 3 on one side of the positioning structure 4, and the orientation structure 3 is perpendicular to the reference plane of the movement direction designed for the positioning structure 4, thereby ensuring that the movement route of the positioning structure 4 is consistent with the designed route; the hinge movable part 12 and the hinge fixed part 11 rotate relative to each other until the hinge movable part 12 abuts against the positioning reference block 42 of the positioning structure 4.
[0027] The connecting line of the upper ends of the multiple positioning reference blocks 42 is parallel to the reference plane of the designed installation surface. When the hinge movable part 12 abuts against the multiple positioning reference blocks 42, the inclination angle of the hinge movable part 12 is consistent with the designed angle. This application uses the assistance of the directional structure 3 and the multiple positioning reference blocks 42 to determine that the angle of the hinge movable part 12 is consistent with the designed angle.
[0028] The positioning device of the present invention overturns the previous idea of using a fixed mechanism to position parts. The present invention adopts a directional structure 3 to quickly and accurately determine the theoretical angle of the installation surface of the positioning hinge movable part 12, thereby meeting the design requirement that the hinge movable part 12 only has a fixed angle but not a fixed position.
[0029] The utility model has a wide range of applications and can be applied to lotus leaf hinges, steel hinges, gooseneck hinges, four-link hinges, steering gears, steering gears and other parts that allow the axis to rotate. The above parts can all use the positioning device of the utility model to quickly find the orientation angle.
[0030] The positioning device of the present invention improves the measurement deviation accuracy of the hinge movable part 12 from 60% to 99%, and improves the yield rate of the hinge movable part 12 from 90% to 95.5%, while saving the working hours of angle adjustment.
[0031] like Figure 1-2 As shown, in one embodiment, the orientation structure 3 includes a slide rail base 731 and an orientation slide rail 32 . The orientation slide rail 32 is arranged on a side of the slide rail base 731 close to the positioning structure 4 and is arranged in a direction perpendicular to the reference plane.
[0032] The setting of the directional slide rail 32 allows the positioning structure 4 to move along the length direction of the directional slide rail 32. Since the directional slide rail 32 is set in a direction perpendicular to the reference plane, when the positioning structure 4 slides inside the directional slide rail 32, the surface of the positioning structure 4 close to the end of the hinge movable part 12 is parallel to the reference plane. Therefore, when the hinge movable part 12 contacts the positioning structure 4, the angle of the hinge movable part 12 can achieve the effect of being consistent with the design angle; it can not only improve the yield rate of the hinge movable part 12, but also save the labor time for angle adjustment.

[0035] like Figure 1-2 As shown, in one embodiment, the positioning structure 4 includes a slider 41 , both sides of which are clamped on the inner sides of the two directional slide rails 32 , and a plurality of positioning reference blocks 42 are provided at one end of the slider 41 close to the hinge movable portion 12 .
[0036] In a preferred embodiment, two positioning reference blocks 42 are provided, and the line connecting the two positioning reference blocks 42 is always parallel to the design angle of the mounting surface of the hinge movable part 12, thereby ensuring that the angle of the positioning reference block 42 is consistent with the design angle, and further ensuring that the angle of the hinge movable part 12 is consistent with the design angle.
[0037] Furthermore, a plurality of positioning reference blocks 42 are provided, and the connecting line of the plurality of positioning reference blocks 42 is always parallel to the design angle of the mounting surface of the hinge movable part 12 .
[0038] Specifically, the slider 41 moves along the length direction of the directional slide rail 32, and the moving trajectory of the slider 41 is limited by the directional slide rail 32, thereby ensuring that the moving route of the slider 41 is consistent with the designed route; the hinge movable part 12 and the hinge fixed part 11 rotate relative to each other until the lower surface of the hinge movable part 12 is in contact with the upper surface of the positioning reference block 42, thereby achieving the positioning of the hinge movable part 12; finally, the hinge movable part 12 is fixed by a fixing mechanism.

The other end of the clamp arm 51 is fixed to the side of the hinge movable part 12 away from the positioning reference block 42.
[0042] Specifically, the hinge movable part 12 and the hinge fixed part 11 rotate relative to each other, and the hinge movable part 12 rotates to the top of the slider 41 and fits with the upper surface of the positioning reference block 42, thereby achieving the positioning of the hinge movable part 12; finally, the hinge movable part 12 is fixed by the clamping arm 51.
[0043] Specifically, a connecting structure is provided between the clamp head 51 and the clamp arm 51, and the connecting structure can drive the clamp arm 51 to perform lifting or opening and closing movements, so that the clamp arm 51, with the assistance of the connecting structure, can fix the hinge movable part 12 by lifting or fixing the hinge movable part 12 by opening and closing; any connecting structure that can achieve this technical effect is included in the protection scope of this application and will not be listed one by one here.
