[0002] At present, the production of door locks requires several process steps such as assembly, fixation, oiling, and testing. Therefore, different types of rivets are needed for fixation during assembly.

[0003] In the existing technology, the production, assembly, fixing and testing are all completed on the same assembly line. In order to cooperate with different workstations, different structures of tooling are required to be used together. In order to improve efficiency, the tooling will not be replaced in the middle, so it will have an impact on some workstations. Figure 3 As described, this structure is a tooling structure drawing of the prior art. The front is a detection drawing, and the door lock is on the side, so the height is greater than the assembly tooling on the rear side, which will affect the assembly surface on the rear side during assembly.

[0025] The screw fixing mechanism 4 includes a mounting bracket 41, a guide plate 42 arranged on the mounting bracket through a guide column, a lifting cylinder 43 for driving the guide plate 42 to move up and down, a horizontal transverse slide rail 44 arranged on the guide plate 42, a screw gun mounting seat 45 installed on the horizontal transverse slide rail through a slider and arranged perpendicular to the horizontal transverse slide rail, a horizontal transverse driving cylinder arranged on the guide plate and used to drive the screw gun mounting seat to move, a horizontal longitudinal first slide rail 46 arranged on the screw gun mounting seat, a screw gun mounting plate 47 installed on the horizontal longitudinal first slide rail through a slider, and a screw gun mounting seat installed on the screw gun mounting seat and used to drive the The first driving cylinder 48 for moving the screw gun mounting plate, the horizontal longitudinal second slide rail provided on the screw mounting plate, the screw gun seat 49 installed on the horizontal longitudinal second slide rail through a slider, the second driving cylinder 491 for driving the movement of the screw gun seat, and the screw gun 492 installed on the screw gun seat; firstly, the entire guide plate 42 is driven to move to a certain height by the jacking cylinder, so as to match a fixed clamping mechanism to fix the door lock, and the screw gun is moved to the front of the fixing hole to be fixed by the horizontal transverse driving cylinder and the first driving cylinder, and then the screw gun is driven by the second driving cylinder to cooperate with the screw locking, thereby ensuring accurate matching and fixed assembly;

[0026] The lifting cylinder drives the entire guide plate up and down to achieve Z-axis control, and the horizontal traverse drive cylinder drives the screw gun mounting base to move horizontally. The X-axis movement control is achieved by driving the screw gun mounting plate horizontally and longitudinally through the first drive cylinder to achieve Y-axis movement control. A second drive cylinder is also provided to drive the movement of the screw gun, so that the distance between the screw gun and the door lock can be accurately maintained, assisting in screw fixing.

[0027] In order to facilitate the feeding of screws, a screw feeding pipe 493 is connected to the outside of the screw gun, through which the screws are fed into the screw gun for fixing;
