They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0021] The following is in conjunction with the appendix Figures 1-3 The present invention will be further described in terms of the embodiments and implementation methods.

[0022] The specific embodiments of this utility model are as follows:

[0023] A pedestal welding positioner includes a support base 9, the upper side of which is connected to a welding support assembly via a rotating assembly;

[0024] The welding support assembly includes a motor cavity 6, with a fixed connecting frame 14 at the upper end of the motor cavity 6. The connecting frame 14 is fixed to the lower side of the support plate 1. The lower side of the support plate 1 is rotatably connected to the center of a rotating wheel 13. The lower two sides of the rotating wheel 13 are respectively fixedly connected to protruding posts 18. Each protruding post 18 is respectively set in the groove of a straight groove rod 15. The middle part of one side of each straight groove rod 15 is respectively fixedly connected to the crossbar of an L-shaped rod 5. The crossbar of each L-shaped rod 5 passes through a slot 16. Each slot 16 is respectively fixed to the lower side of the support plate 1. The center of the rotating wheel 13 is fixedly connected to the output shaft of a stepper motor fixed inside the motor cavity 6.

[0025] The upper end of the vertical rod of each L-shaped rod 5 is fixedly connected to the fixed end of the first motor 4, and the output shaft of each first motor 4 is fixedly connected to the clamping mechanism.

[0026] In this embodiment, the first motor 4 drives the clamping mechanism to move, thereby enabling the clamping mechanism to rotate the clamped parts and adjust the parts to the required alignment angle.

[0027] The stepper motor drives the rotating wheel 13 to rotate, which in turn drives the protruding post 18 to rotate. The protruding post 18 rotates in the groove of the straight groove rod 15, causing the straight groove rod 15 to move back and forth. The straight groove rod 15 drives the L-shaped rod 5 to move along the slot 16, thereby connecting the workpieces clamped by the clamping mechanism together.

[0028] The clamping mechanism includes a circular plate 3, which is fixedly connected to the movable end of the first motor 4. A plurality of circumferentially evenly arranged sliding grooves 19 are provided on one side of the circular plate 3. Each sliding groove 19 is provided with a slider 20. Each slider 20 is threadedly connected to a screw 22. The screw 22 is rotatably connected to the circular plate 3. The slider 20 is fixedly connected to a clamping rod 21.

[0029] In this embodiment, by placing the workpiece between the clamping rods 21, rotating the screw 22 causes the slider 20, which is threadedly connected to it, to move. The slider 20 causes the clamping rods 21 to move, so that the clamping rods 21 abut against the surface of the workpiece. Each clamping rod 21 is adjusted in this way to achieve clamping of the workpiece.

[0030] The rotating assembly includes an arched bracket 8, which is fixed on the support base 9. One upper end of the arched bracket 8 is rotatably connected to a connecting rod 10, and the other upper end of the arched bracket 8 is rotatably connected to the end of the outer shell of an electric push rod 2 11.

One end of the connecting rod 2 7 is rotatably connected to the other end of the connecting rod 10, and the other end of the connecting rod 2 7 is fixedly connected to the lower side of the motor cavity 6.

[0031] In this embodiment, the extension of the telescopic rod of the electric push rod 2 11 of the rotating component can drive the connecting rod 1 10 to swing. The connecting rod 1 10 drives the connecting rod 2 7 and the electric push rod 3 12 to swing, thereby realizing the swing of the clamping mechanism. The extension of the telescopic rod of the electric push rod 3 12 can drive the connecting rod 2 7 to swing, thereby realizing the swing of the clamping mechanism. In this way, the position of the clamping mechanism can be adjusted, which is convenient for changing the welding station.

[0032] The upper side of the support plate 1 is provided with a transverse through groove 2.

[0033] The method of using this utility model is as follows:

[0034] In use, the workpiece is placed between the clamping rods 21, and the slider 20 is moved by rotating the screw 22 so that the clamping rods 21 abut against the surface of the workpiece to achieve clamping. The clamping mechanism is moved by the first motor 4 to adjust the workpiece to the required alignment angle.

[0035] Start the stepper motor to drive the rotating wheel 13 to rotate. Through the linkage of the protruding post 18, the straight groove rod 15 and the L-shaped rod 5, the clamping mechanism moves closer to each other and the workpiece is docked.

[0036] According to the needs of the welding station, the extension and retraction of electric push rod 11 and electric push rod 3 12 drive connecting rod 10 and connecting rod 7 to swing, thereby adjusting the position of the clamping mechanism.
