However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0018] Embodiment 1, as Figure 1-Figure 4 As shown, the present invention provides a frame welding positioner, including a base 1, a first motor 2 is fixedly installed on the outer surface of one side of the base 1, a worm 21 is rotatably arranged near the middle of the base 1, the outer surface of the worm 21 is symmetrically meshed with two turbines 23, the output end of the first motor 2 slides through the outer surface of the base 1 and extends to the inside of the base 1, the output end of the first motor 2 is connected to one end of the worm 21, the top of the base 1 is symmetrically fixedly connected with side frames 3 near the edges on both sides, an embedded groove 31 is opened inside the side frame 3, a slider 32 is slidably embedded inside the embedded groove 31, a threaded screw 24 is fixedly connected to the top of the turbine 23, the outer surface of the threaded screw 24 is threaded through the outer surface of the slider 32, and the two A supporting plate 4 is arranged between the outer surfaces of the two sliders 32, and the outer surfaces of both sides of the supporting plate 4 are symmetrically fixedly connected with connecting shafts 41, and the outer surface of the connecting shaft 41 passes through the outer surface of the slider 32, and a motor seat 33 is installed on the outer surface of one side of one of the sliders 32, and a second motor 34 is installed on the top of the motor seat 33, and the output end of the second motor 34 is connected to the end face of one of the connecting shafts 41, and a first clamping block 42 is fixedly connected to the top of the supporting plate 4 near the front side, and a fixing block 43 is fixedly connected to the top of the supporting plate 4 near the rear side, and an adjusting screw rod 44 is threadedly passed through the center of the rear surface of the fixing block 43, and the front end of the adjusting screw rod 44 is rotatably connected to the second clamping block 45, and the second clamping block 45 cooperates with the first clamping block 42.

[0019] The effect achieved by the entire embodiment 1 is that when the device is used to weld the frame, the worm 21 is driven to rotate by starting the first motor 2. At this time, the spiral pattern on the surface of the worm 21 drives the two turbines 23 to rotate synchronously in the same direction, thereby driving the two threaded screws 24 to rotate. When the two threaded screws 24 rotate, they drive the slider 32 to rise and fall, and then drive the supporting plate 4 to move to the lowest point, which makes it convenient for workers to place the frame to be welded on the supporting plate 4, and then rotate the adjusting screw 44 to drive the second clamping block 45 to move toward the first clamping block 42, so as to fix the frame. After that, the two sliders 32 are lifted and then cooperated with the supporting plate 4 to move the frame to a suitable height, and then the frame can be manually welded with the six-axis electric welding robot. During the process, the second motor 34 can be started to drive the connecting shaft 41 to rotate, thereby driving the supporting plate 4 to flip, so as to adjust the frame to a vertical or inclined state, which is convenient for welding. After welding is completed, the first motor 2 cooperates with the worm 21 and the turbine 23 to drive the threaded screw 24 to rotate in the opposite direction, thereby driving the two sliders 32 to move to the lowest point, which greatly facilitates the operator to unload the frame. It not only saves time and effort, but also has high safety and will not cause safety hazards such as falling and injuring people. The first clamping block 42 and the second clamping block 45 are both U-shaped, which is convenient for fixing the frame. The motor seat 33 is installed on the surface of the slider 32 and extends to the outside of the side frame 3. It is mainly used for installing the second motor 34. The fixing block 43 is mainly used to install the adjusting screw 44 and limit the limit rod 46.

[0020] Embodiment 2, as Figure 1-Figure 4 As shown, the rear surface of the second clamping block 45 is symmetrically fixedly connected with a limiting rod 46, the outer surface of the limiting rod 46 slides through the outer surface of the fixed block 43, the outer surface of the worm 21 is fixedly connected with the first bearing 22 near the end surface, the outer surface of the first bearing 22 is connected to the inner surface wall of the base 1, the outer surface of the connecting shaft 41 is fixedly connected with the second bearing 35, and the outer surface of the second bearing 35 is connected to the inner surface wall of the slider 32.

[0021] The effect achieved by the entire embodiment 2 is that two limit rods 46 are provided to limit the second clamping block 45, so that when the adjusting screw 44 is rotated, the second clamping block 45 moves more smoothly, and the end face of the worm 21 and the inner wall of the base 1 are connected by the first bearing 22, which facilitates the rotation of the worm 21, and the connecting shaft 41 is connected to the slider 32 by the second bearing 35, which facilitates the rotation of the connecting shaft 41.

[0022] Working principle: When the device is used to weld a vehicle frame, the first motor 2 is started to drive the worm 21 to rotate. At this time, the spiral pattern on the surface of the worm 21 drives the two turbines 23 to rotate synchronously in the same direction, thereby driving the two threaded screws 24 to rotate. When the two threaded screws 24 rotate, they drive the slider 32 to rise and fall, and then drive the supporting plate 4 to move to the lowest point. Then, it is convenient for workers to place the frame to be welded on the supporting plate 4, and then rotate the adjusting screw 44 to drive the second clamping block 45 to move toward the first clamping block 42, so as to fix the frame. After that, by raising the two sliders 32 After starting, cooperate with the supporting plate 4 to move the frame to a suitable height, and then cooperate with the six-axis electric welding robot to manually weld the frame. During the welding process, the second motor 34 can be started to drive the connecting shaft 41 to rotate, thereby driving the supporting plate 4 to flip, and adjusting the frame to a vertical or inclined state, which is convenient for welding. After the welding is completed, the first motor 2 cooperates with the worm 21 and the turbine 23 to drive the threaded screw 24 to rotate in the opposite direction, thereby driving the two sliders 32 to move to the lowest point, which greatly facilitates the operator to unload the frame, which not only saves time and effort, but also has higher safety and will not cause safety hazards such as falling and injuring people.
