Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The door lock hook reinforcement plate welding tooling provides two technical solutions:

[0027] like Figure 1-3 Figure 5 shows a first embodiment: comprising a support box 1 and a welding assembly 2, a door lock hook placement platform 3 is fixedly connected to the top of the support box 1, and a feeding mechanism for continuously feeding the door lock hook is provided below the door lock hook placement platform 3, and the feeding mechanism comprises:

[0028] The continuous feeding component 4 includes two left and right U-shaped mounting seats 41, both of which are fixedly connected to the top of the supporting box body 1, and the insides of the two U-shaped mounting seats 41 are rotatably connected with pulleys 42, and the two pulleys 42 are connected through a belt 43 for transmission, and the outer surface of the belt 43 is equidistantly fixedly connected with a plurality of pre-tightening components 45 for clamping the door lock hook, and the inside of the belt 43 is provided with a plurality of through grooves 44 at equal distances, and the positions of the plurality of through grooves 44 respectively correspond to the positions of the plurality of pre-tightening components 45, and the front of the right U-shaped mounting seat 41 is fixedly connected with a stepper motor 46, and the output end of the stepper motor 46 is fixedly connected to the pulley 42.

[0029] The preload assembly 45 includes a square box 451, and the front and back sides of the square box 451 are slidably connected with T-shaped slide bars 452, and the two T-shaped slide bars 452 penetrate the square box 451 and extend into the square box 451. One end is fixedly connected with a pressure block 453, and the two pressure blocks 453 are provided with an arc groove 454 on the opposite side. A limit spring 455 is fixedly connected between the end of the T-shaped slide bar 452 and the square box 451, and the limit spring 455 is sleeved on the outside of the T-shaped slide bar 452.

[0030] The pushing assembly 6 is arranged below the continuous feeding assembly 4, and is used to push the door lock hook in the pre-tightening assembly 45 close to the reinforcing plate. The pushing assembly 6 includes a second support frame 61, and the top of the second support frame 61 is fixedly connected to a cylinder 62, and the cylinder 62 is located in the middle position of the belt 43, and the output end of the cylinder 62 is fixedly connected to a push rod 63.

[0031] When loading the door lock hook, the operation is performed through the continuous feeding component 4, which is convenient and quick, and after the welding of the previous door lock hook is completed, the next door lock hook can quickly enter the processing area, which greatly reduces the loading time and improves the practicability of the device when used.

[0032] like Figure 2 and 4The second embodiment is shown, and the main difference from the first embodiment is that a feeding component 5 is arranged on the left side of the continuous feeding component 4, and the feeding component 5 is used to feed the continuous feeding component 4, and the feeding component 5 includes a first support frame 51, and the first support frame 51 is fixed to the top of the support box 1 and is erected on the left side above the continuous feeding component 4, a material box 52 is fixedly connected in the middle of the first support frame 51, and the distance between the bottom of the material box 52 and the top of the square box 52 is close, and the spacing distance is the same as the thickness of the baffle 56, and a feeding port 54 is opened on the left side of the material box 52, a hydraulic cylinder 53 is fixedly connected to the top of the material box 52, and the output end of the hydraulic cylinder 53 passes through the material box 52 and extends to one end of the material box 52, and is fixedly connected to a push plate, a driving motor 55 is fixedly connected to the top of the first support frame 51, and the output end of the driving motor 55 passes through the bottom of the first support frame 51, and the output end of the driving motor 55 is fixedly connected to the baffle 56.

[0034] The stepper motor 46 rotates the same angle each time when loading, and each time the stepper motor 46 rotates once, the hydraulic cylinder 53 pushes a door lock hook, and the drive motor 55 rotates one circle.

[0035] When in use, multiple door lock hooks are stacked and placed inside the material box 52, and the hydraulic cylinder 53 works and pushes the door lock hook into the interior of the pre-tightening component 45. When the door lock hook enters the pre-tightening component 45, it contacts the two pressure blocks 453 and pushes the two pressure blocks 453 to move, thereby clamping the door lock hook between the two pressure blocks 453, and starting the stepper motor 46 to rotate the pulley 42. The pulley 42 rotates and drives another pulley 42 to rotate through the belt 43. At this time, the belt 43 rotates continuously, thereby driving the pre-tightening component 45 to move. When the pre-tightening component 45 enters directly below the processing area, the stepper motor 46 stops working, and the cylinder 62 starts and pushes the push rod 63 to move upward. The push rod 63 enters the interior of the pre-tightening component 45 from the through groove 44 and pushes the door lock hook close to the bottom of the reinforcing plate. The welding component 2 is started to weld the door lock hook and the reinforcing plate. After welding is completed, the stepper motor 46 is started and rotated a certain angle to allow the next pre-tightening component 45 to enter the processing area.
