Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts assembly equipment, in particular to a bent pipe hinge assembly tool. Background Art
[0002] The most commonly used hinge for car trunk lids is the elbow hinge. The hinge switch operates smoothly, and the beautiful appearance enhances the visual effect. When the hinge opens and reaches the top dead center, there is no obvious impact due to the damping effect of the elastic buffer air spring. Therefore, the elbow hinge is widely used. When the elbow hinge is assembled, the lateral deformation will increase greatly due to the long length direction of the outer dimension. Therefore, it is not easy to ensure the docking size of the elbow hinge during installation, which is prone to interference appearance defects, affecting the OEM vehicle quality and adjustment time.

DETAILED DESCRIPTION
[0012] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0013] like Figure 1-2 As shown, the utility model is used for assembling the elbow hinge of the rear cover. The elbow hinge includes an elbow and stamping parts at both ends of the elbow. One of the stamping parts is welded to the elbow before assembly, and the other stamping part is assembled together with the tube body assembly by bolt connection through a locking nut 14 and a locking shaft 13.
[0014] The base plate 1 is supported at the bottom, and the base plate is connected to the positioning plate 3 by the vertical plate 2. The positioning plate 3 supports the elbow hinge. A clamp mounting plate 22 is arranged above the positioning plate 3. The stamping parts are placed on the clamp mounting plate 22. The clamp mounting plate 22 is provided with positioning reference pins 5 to guide the stamping parts during the placement process. The first clamp 4 and the second clamp 8 are respectively arranged on the clamp mounting plates 22 on both sides of the vertical plate 2. The first clamp 4 and the first clamp 8 are used to clamp the stamping parts after positioning to ensure the stable position of the product on the assembly tooling provided by the utility model.
[0015] The first measuring pin 10, the second measuring pin 11, the third measuring pin 12, the fourth measuring pin 15, the fifth measuring pin 16, the first detection pin 17, the second detection pin 18 and the fourth measuring pin 21 constitute a positioning and detection structure for positioning and detecting the bent pipe, wherein the lateral vertical plate 6 and the opening measurement plate 7 are used for measuring the open state, and the positioning hole on the tail cover in the open state is detected by the first detection pin 17 and the second detection pin 18.
[0016] The utility model is designed by simulating the actual vehicle loading state of the bent pipe hinge, with the base plate 1 as the basic plane, the vertical plate 2 connected to the positioning plate 3 to assist in fixing the bent pipe hinge, the positioning reference pin 5 is used to position the stamping part of the part, and the positioning pin 9, the first measuring pin 10, the second measuring pin 11, the third measuring pin 12, the fourth measuring pin 15, the fifth measuring pin 16 and the sixth measuring pin 21 are respectively inserted into the corresponding holes of the bent pipe to fix the position of the bent pipe on the vertical plate 2, and the first measuring pin 10, the second measuring pin 11, the third measuring pin 12, the fourth measuring pin 15, the fifth measuring pin 16 and the sixth measuring pin 21 are respectively inserted into the corresponding holes of the bent pipe to fix the position of the bent pipe on the vertical plate 2. Pin 12, the fourth measuring pin 15, the fifth measuring pin 16, the first detection pin 17, the second detection pin 18 and the fourth measuring pin 21 are used to position and detect the bent pipe, and the locking shaft 13 is inserted. The locking nut 14 is tightened to 20Nm with a torque wrench. The locking nut 14 adopts an M8 nut. The locking nut 14 can be tightened to position the stamping part on the bent pipe. The reference positioning pin 9 is used to position the body part on the assembly tool to ensure the theoretical position of the stamping part on the body and use the first pressing clamp 4 and the second pressing clamp 8 to press the bent pipe hinge.
[0017] Keep the second clamp 8 in a clamped state, remove the remaining inspection pins and loosen the first clamp 4, open the tail cover around the axis so that it contacts the opening measuring plate 7 at the top of the lateral vertical plate 6, and use the first inspection pin 17 and the second inspection pin 18 to directly measure the position of the cover hole, thereby improving the hinge assembly accuracy, avoiding unqualified parts from leaving the factory, reducing customer complaints, and lowering quality costs.
