[0021] like Figures 1 to 4As shown, this embodiment proposes a hinge control fixture for servo-controlled flower fence welding, including a mounting plate 1, which is slidably connected to one end of the top of the main frame 4, and a length control unit 2 is provided at the bottom of the mounting plate 1 for driving the mounting plate 1 to move along the length direction of the main frame 4, and a hinge positioning mechanism 3 is provided at the top of the mounting plate 1. The hinge positioning mechanism 3 includes two parallel slide rails 31, and the two slide rails 31 are both arranged parallel to the mounting plate 1. The lengths of the two slide rails 31 are both smaller than the length of the mounting plate 1, and the two slide rails 31 are fixedly connected to the top of the mounting plate 1. Both ends of the two slide rails 31 are slidably connected to sliders 32, and the tops of the two sliders 32 at the same end are provided with hinge clamping members 33 for clamping the flower fence hinge by cooperating with the sliding of the sliders 32, and the top of the mounting plate 1 is provided with a driving member 34 for driving the two sliders 32 on the slide rails 31 to slide toward or away from each other.

[0022] The length control unit 2 drives the mounting plate 1 to move along the length direction of the main frame 4 and to the welding position of the hinge of the flower fence, and then the driving member 34 drives the two sliders 32 to slide toward or away from each other, thereby adjusting the spacing between the two sliders 32, so that the two sliders 32 move to the two ends of the flower fence hinge, and then the hinge clamping member 33 is controlled to clamp the flower fence hinge, so that the flower fence hinge is stably pressed onto the frame of the flower fence, which makes it convenient to accurately fix the flower fence hinge on the frame of the flower fence. The whole process can realize the rapid positioning of flower fence hinges of different sizes according to flower fences of different sizes. The operation is simple, which greatly improves the working efficiency.

[0023] Furthermore, the hinge clamping member 33 includes a lower clamping seat 331, which is fixedly connected to the top of the corresponding slider 32, and one end of the top of the lower clamping seat 331 is fixedly connected to the first cylinder 332, and the output end of the first cylinder 332 is fixedly connected to the connecting plate 333, and one end of the connecting plate 333 is fixedly connected to the pressure rod 334, and the bottom end of the pressure rod 334 is fixedly connected to the upper clamping seat 335, and the upper clamping seat 335 is arranged parallel to the lower clamping seat 331, and the length of the upper clamping seat 335 is smaller than the length of the lower clamping seat 331, and one end of the lower clamping seat 331 is fixedly connected to the fixing plate 336, and the outer side of the fixing plate 336 is fixedly connected to the second cylinder 337, and the output end of the second cylinder 337 is fixedly connected to the flower fence frame top rod 338 that conflicts with the flower fence frame.

[0024] By controlling the first cylinder 332 to make the connecting plate 333 move downward, the pressure rod 334 drives the upper clamping seat 335 to move downward and interfere with one side of the flower fence hinge, so that the upper clamping seat 335 presses one side of the flower fence hinge to the top of the flower fence frame, and then controls the second cylinder 337 to make the flower fence frame top rod 338 press the other side of the flower fence hinge, so that the other side of the flower fence hinge is pressed to the side of the flower fence frame, so that the flower fence frame hinge is stably installed on the flower fence frame, which can facilitate the fixation of the flower fence frame.

[0025] Furthermore, the driving member 34 includes two reduction servo motors 341, which are respectively fixedly mounted at both ends of the mounting plate 1. The output shafts of the two reduction servo motors 341 are fixedly connected to a screw rod 342. The middle part of the mounting plate 1 is fixedly connected to two parallel fixed seats 343. One end of the two screw rods 342 is rotatably connected to the two fixed seats 343 respectively. The bottoms of the two lower clamping seats 331 are fixedly connected to a screw nut 344.

The two screw nuts 344 are symmetrically distributed along the center line of the mounting plate 1.

[0026] Working principle: First, place the frame of the flower fence on the lower clamping seat 331, and then drive the mounting plate 1 to move along the length direction of the main frame 4 and move to the welding position of the hinge of the flower fence through the length control unit 2, and then start the two reduction servo motors 341 to make the two screw rods 342 rotate synchronously. Since the screw threads of the two screw rods 342 have opposite directions, the two screw nuts 344 move toward or away from each other, which makes the two lower clamping seats 331 move toward or away from each other, and realizes the adjustment of the spacing between the two lower clamping seats 331, so that the two lower clamping seats 331 move to the two ends of the flower fence hinge, and then control the first cylinder 332 to make the connection The connecting plate 333 moves downward, causing the pressure rod 334 to drive the upper clamping seat 335 to move downward and interfere with one side of the flower fence hinge, which causes the upper clamping seat 335 to press one side of the flower fence hinge to the top of the flower fence frame, and then controls the second cylinder 337 to make the flower fence frame top rod 338 press the other side of the flower fence hinge, so that the other side of the flower fence hinge is pressed to the side of the flower fence frame, so that the flower fence frame hinge is stably installed on the flower fence frame, which can facilitate the fixation of the flower fence frame. The whole process can realize the rapid positioning of flower fence hinges of different sizes according to flower fences of different sizes. The operation is simple, which greatly improves the working efficiency.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
