[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0019] refer to Figures 1-5The automatic screw-locking mechanism for a bracket with adjustable positioning function, shown, includes a positioning platform 1 and an automatic screw-locking mechanism 2. A first adjusting positioning component 3 and a second adjusting positioning component 4 are respectively arranged on both sides of the positioning platform 1. The first adjusting positioning component 3 includes a first lifting seat 301, a sliding ramp 302, and a roller 303. Both the first lifting seat 301 and the sliding ramp 302 are slidably connected to the positioning platform 1. The positioning platform 1 can guide and limit the lifting of the first lifting seat 301 and the sliding of the sliding ramp 302. The roller 303 is rotatably connected to the first lifting seat 301, and the sliding ramp 302 is rotatably connected to the roller. The shaft 303 is tangent to each other. A spring 304 is provided between the first lifting seat 301 and the positioning table 1. A first positioning seat 5 is fixedly connected to the first lifting seat 301. The second adjustment and positioning assembly 4 includes a servo rotation mechanism 401, a rotating sleeve 402 and a second lifting seat 403. A screw 404 is fixedly connected to the rotating table of the servo rotation mechanism 401. The rotating sleeve 402 is threadedly connected to the screw 404. The rotating sleeve 402 is rotatably connected to the second lifting seat 403. A second positioning seat 6 and a guide post 8 are fixedly connected to the upper and lower sides of the second lifting seat 403 respectively. The guide post 8 is slidably connected to the screw 404.

[0020] An adjusting screw 305 is threadedly connected to the positioning table 1 next to the first adjusting positioning component 3. The adjusting screw 305 is slidably connected to the sliding inclined table 302. Rotating the adjusting screw 305 can drive the sliding inclined table 302 to slide and adjust.

[0021] The first positioning seat 5 and the second positioning seat 6 are both fixedly connected to the side of the clamping cylinder 7. The first positioning seat 5 and the second positioning seat 6 are both provided with relief grooves corresponding to the piston rod of the clamping cylinder 7. When the piston rod of the clamping cylinder 7 extends, it can pass through the relief groove to clamp the entire bracket pre-assembled component.

[0022] Both the first lifting seat 301 and the positioning table 1 have limit holes. The spring 304 is located in the limit hole, and the limit hole 304 can prevent the spring 304 from being misaligned when it is extended or retracted.

[0023] The servo rotation mechanism 401 is fixedly connected to the positioning table 1. The screw 404 has a guide hole, and the guide post 8 is slidably connected to the guide hole. The guide hole can guide the sliding of the guide post 8.

[0024] The inner wall of the rotating sleeve 402 is threadedly connected to the outer wall of the screw 404. The guide post 8 is located inside the rotating sleeve 402. The height of the second lifting seat 403 and the second positioning seat 6 can be adjusted by rotating the rotating sleeve 402.

[0025] The working principle of this utility model is as follows: First, adjust the height of the first positioning seat 5 and the second positioning seat 6 according to the height difference between the two ends of the bracket. When adjusting the height of the first positioning seat 5, adjust the position of the sliding inclined table 302 by rotating the adjusting screw 305. Under the sliding of the sliding inclined table 302, the first lifting seat 301 is adjusted accordingly. When adjusting the height of the second positioning seat 6, adjust the second lifting seat 403 by rotating the rotating sleeve 402. Then, adjust the angle of the second positioning seat 6 according to the angle of the end of the bracket. The angle can be adjusted by driving the screw 404, the rotating sleeve 402, and the guide column 8 to rotate synchronously through the servo rotating mechanism 401.

[0026] During processing, after positioning the bracket pre-assembly along the first positioning seat and the second positioning seat 6, the bracket pre-assembly is clamped by the clamping cylinder 7, and then the screws of the bracket pre-assembly are tightened by the automatic screw-locking mechanism 2.

[0027] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
