The E-shaped base 1 and the front baffle 2 are both made of alloy steel. The aluminum alloy plate is placed on the top of the E-shaped base 1, and one side of the aluminum alloy plate is against the outer wall of the front baffle 2;

[0019] A back strip 401 for slidingly cooperating with the fixed right-angle frame 3 is fixed on the back of the movable right-angle frame 4, a screw linear module 11 for driving the movable right-angle frame 4 to slide on the X-axis is installed on the back of the fixed right-angle frame 3, a main shaft 6 and a secondary shaft 7 are rotatably installed on the outer walls of the opposite sides of the fixed right-angle frame 3 and the movable right-angle frame 4, a pulley clamping assembly 10 is arranged on the opposite ends of the main shaft 6 and the secondary shaft 7, a pulley transmission structure 9 is arranged on the ends of the main shaft 6 and the secondary shaft 7 that are away from each other, a stepper motor 5 is installed on the outer wall of one side of the fixed right-angle frame 3, the output end of the stepper motor 5 drives the main shaft 6 to rotate through the pulley transmission structure 9, a spline transmission structure 8 is installed on the output end of the stepper motor 5, and one end of the spline transmission structure 8 is connected to the secondary shaft 7 through another pulley transmission structure 9 for power connection;

[0020] The spline transmission structure 8 includes an inner spline shaft 801 and an outer spline shaft 802 which are rotatably mounted on the outer walls of the fixed right angle frame 3 and the movable right angle frame 4. One end of the outer spline shaft 802 extends to the inside of the inner spline shaft 801. When controlling the spacing between the two pulley clamping assemblies 10, the screw linear module 11 drives the back bar 401 and the movable right angle frame 4 to move horizontally, so that the spacing between the two pulley clamping assemblies 10 is adjusted. In this process, the outer spline shaft 802 slides inside the inner spline shaft 801.

[0021] One end of the inner spline shaft 801 is fixedly connected to the output end of the stepper motor 5 through a coupling, and one end of the outer spline shaft 802 passes through the outside of the movable right-angle frame 4 and is connected to the secondary shaft 7 through the pulley transmission structure 9. The rotational power of the stepper motor 5 is transmitted to the secondary shaft 7 through the inner spline shaft 801, the outer spline shaft 802 and the pulley transmission structure 9. At this time, the main shaft 6 and the secondary shaft 7 rotate synchronously, realizing the function of synchronous flipping of the two pulley clamping assemblies 10;

[0022] The pulley clamping assembly 10 includes a support plate 1001 fixed on the opposite ends of the main shaft 6 and the secondary shaft 7, and a vertical arm 1002 fixed on the top of the support plate 1001, a clamping arm 1005 is slidably mounted on one end of the surface of the vertical arm 1002, a pulley pitch adjustment structure 1004 for driving the clamping arm 1005 to slide is mounted on the surface of the vertical arm 1002, a motor 1003 for driving the pulley pitch adjustment structure 1004 to work is mounted on the back of the vertical arm 1002, guide rods are fixed on both sides of the surface of the vertical arm 1002, and a sliding sleeve that slidably cooperates with the guide rod is fixed on the back of the clamping arm 1005;

At this time, the clamping arm 1005 can move toward the direction of the front baffle 2, so that the aluminum alloy plate is firmly pressed against the outer wall of the front baffle 2 through the clamping arm 1005, so that the aluminum alloy plate can be more accurately positioned during the welding process, thereby improving the accuracy and quality of welding.

At this time, the spacing between the two pulley clamping assemblies 10 in the horizontal direction is debugged, and the spacing between the two pulley clamping assemblies 10 is debugged to meet the requirements of aluminum alloy plates of different widths or lengths. In this process, the spline transmission structure 8 is correspondingly extended or contracted, and the power connection between the main shaft 6 and the secondary shaft 7 is ensured by the spline transmission structure 8 and the pulley transmission structure 9. After the spacing between the two pulley clamping assemblies 10 is debugged, the staff turns on the stepper motor 5 again to work, and the rotation of the stepper motor 5 The power is transmitted to the main shaft 6 through one of the pulley transmission structures 9, and the secondary shaft 7 rotates synchronously driven by the other pulley transmission structure 9 and the spline transmission structure 8, that is, the main shaft 6 and the secondary shaft 7 synchronously drive the pulley clamping assembly 10 to flip until the pulley clamping assembly 10 flips to a horizontal state, so that the pulley clamping assembly 10 and the E-shaped base 1 are in a parallel state, and then the pulley clamping assembly 10 actively presses the aluminum alloy plate against the outer wall of one side of the front baffle 2, so that the aluminum alloy plate is stably clamped by the pulley clamping assembly 10 and the front baffle 2. The device can be quickly debugged and complete the clamping of the plate. At this time, the welding work can start faster, thereby improving the overall production efficiency. Compared with manually adjusting each parameter to adapt to plates of different specifications, automatic and fast debugging can greatly reduce the need for manual operation, so that the welding positioning device has greater flexibility and adaptability, and produces products of different specifications.
