[0029] like Figures 1-5 As shown, the utility model discloses a vehicle door lock positioning and mounting structure, including a lock mounting plate 3, a side panel reinforcement plate 2 and a side panel outer panel 1 welded in sequence inside and outside, and mounting holes are respectively opened on the side panel outer panel 1, the side panel reinforcement plate 2 and the lock mounting plate 3, which are respectively a first mounting hole 12, a second mounting hole 22 and a third mounting hole 32, and a lock nut 4 corresponding to the third mounting hole 32 is connected to the side of the lock mounting plate 3 away from the side panel reinforcement plate 2; the outer edges of the first mounting hole 12, the second mounting hole 22 and the third mounting hole 32 are respectively provided with corresponding first identification lines 11, second identification lines 21 and third identification lines 31; the size of the second mounting hole 22 is not larger than the size of the first mounting hole 12, and the size of the third mounting hole 32 is smaller than the size of the second mounting hole 22.
[0030] First, the lock nut 4 is fixed to the lock mounting plate 3 using resistance welding, ensuring that the lock nut 4 is concentric with the third mounting hole 32. Then, the lock mounting plate 3 is attached to the side panel reinforcement 2, and when viewed from the outside of the side panel reinforcement 2, the second identification line 21 and the third identification line 31 are aligned. The lock mounting plate 3 and the side panel reinforcement 2 are then fixed using resistance welding. Finally, the side panel reinforcement 2 is attached to the side panel outer panel 1, and when viewed from the outside of the side panel outer panel 1, the third identification line 31 is aligned with the first identification line 11. The side panel reinforcement 2 and the side panel outer panel 1 are then fixed using resistance welding. Using the identification line positioning method to control the relative positions of the side panel outer panel 1, the side panel reinforcement 2, and the lock mounting plate 3 allows for quick and precise positioning of the door lock on the side panel, reducing labor intensity. Furthermore, the door lock position can be pre-adjusted and controlled before the cab body is painted, effectively protecting the cab body finish, reducing tooling development costs, and improving production efficiency.
[0031] When the door lock is installed, a bolt is passed through the through hole of the door lock, the first mounting hole 12 , the second mounting hole 22 and the third mounting hole 32 , and is screwed with the lock nut 4 for positioning and installation.
[0032] Among them, the first identification line 11, the second identification line 21, and the third identification line 31 each include two marking lines. The two marking lines have an extended intersection point, and the intersection point is located at the center position of the corresponding mounting hole, ensuring the accuracy of positioning for the three mounting holes (the first mounting hole 12, the second mounting hole 22, and the third mounting hole 32).
[0033] Among them, the two marking lines are perpendicularly arranged, realizing the convenience of positioning.
[0034] Furthermore, the first mounting hole 12, the second mounting hole 22, and the third mounting hole 32 are each set to two; one of the marking lines penetrates through the center positions of the paired mounting holes. The marking line is formed by stamping, which is convenient for the formation of the marking line and easy to implement.
[0035] Among them, both ends of the latch mounting plate 3 are connected with welding parts through elastic bending parts 33, and the welding parts are fixedly welded to the side wall reinforcement plate 2. The latch mounting plate 3 is only welded and positioned to the side wall reinforcement plate 2 through the welding parts. When installing the door latch, the position of the third mounting hole 32 (latch nut 4) can be finely adjusted according to the bolt, realizing the convenience of screw connection installation.

The diameters of the first mounting hole 12 and the second mounting hole 22 are both 15 mm; the diameter of the third mounting hole 32 is 9 mm. The reliability of the alignment and positioning of the identification lines can be realized, and the three mounting holes and the latch nut 4 are integrally in a stepped shape, playing a certain guiding role for the installation of the bolt and facilitating the screwing connection between the bolt and the latch nut 4.
[0038] Among them, the latch nut 4 is a flange nut, and the flange surface of the latch nut 4 is fitted and welded to the latch mounting plate 3, realizing the reliability of the welding between the latch nut 4 and the latch mounting plate 3.
[0039] The positioning and installation structure of the vehicle door lock catch. First, the lock catch nut 4 and the lock catch mounting plate 3 are fixed by resistance welding to make the lock catch nut 4 concentric with the third mounting hole 32. Then, the lock catch mounting plate 3 is fitted to the side wall reinforcement plate 2. When observing from the outside of the side wall reinforcement plate 2, align the second marking line 21 and the third marking line 3 with each other, and fix the lock catch mounting plate 3 and the side wall reinforcement plate 2 by resistance welding. Finally, the side wall reinforcement plate 2 is fitted to the outer side wall plate 1. When observing from the outside of the outer side wall plate 1, align the third marking line 31 and the first marking line 11 with each other, and fix the side wall reinforcement plate 2 and the outer side wall plate 1 by resistance welding. By using the marking line positioning method to control the relative positions of the outer side wall plate 1, the side wall reinforcement plate 2 and the lock catch mounting plate 3, the position of the vehicle door lock catch (mounting part) on the side wall can be accurately positioned quickly, reducing the labor intensity. And before painting the cab body, the position of the vehicle door lock catch can be pre-adjusted and controlled, which can effectively protect the topcoat of the cab body, reduce the tooling development cost and improve the production efficiency.
