[0021] like Figures 1-2 As shown, this embodiment provides an automatic welding positioner, including a positioner body, which includes a positioner base 13, a clamping assembly, and a swinging assembly.

[0022] like Figure 1 As shown, the positioner base 13 has a first column 1 and a second column 2 on both sides along its length for mounting the swing assembly. The swing assembly includes a swing seat 3, a first rocker arm 9 and a second rocker arm 10. The first rocker arm 9 is mounted on the first column 1 and the second rocker arm 10 is mounted on the second column 2. Both the first rocker arm 9 and the second rocker arm 10 are provided with flanges of the same size.

[0023] Specifically, the first column 1 is provided with a motor assembly for driving the first rocker arm 9 to swing. The motor assembly includes a second motor 14 and a reducer for limiting the swing speed. The second motor 14 is connected to the reducer. The reducer is provided with a flange of the same size as the flange on the first rocker arm. The reducer is connected to the first rocker arm 9 by threads.

[0024] The second column 2 is equipped with a rotary shaft positioned opposite the motor shaft of the second motor 14. The rotary shaft has a bearing housing with a flange, and is threadedly connected to the second rocker arm 10. The second motor 14 drives the first rocker arm 9 to swing, which in turn drives the swing seat 3 to swing in the front-to-back direction. Simultaneously, the second rocker arm 10 swings back and forth with the swing seat 3. The swing direction and speed of the second rocker arm 10 and the first rocker arm 9 are consistent, allowing the workpiece to achieve angular displacement on the fixture assembly, thereby meeting specific processing requirements.

[0025] like Figure 1 As shown, a clamping assembly is provided on the swing seat 3. The clamping assembly is set between the first column 1 and the second column 2 via the swing seat 3. The clamping assembly includes a clamping bracket, a nut seat 5, and a transmission screw 4 that drives the nut seat 5 to move. A first motor 7 that drives the transmission screw to rotate is provided on the clamping bracket. Nut seats 5 are provided at both ends of the transmission screw. Claws 11 for clamping workpieces are provided on the nut seats 5. The nut seats on the same transmission screw move towards each other at the same time. The workpiece is clamped by the claws, which ensures the stability and accuracy of the processing. The simultaneous movement of the two nut seats towards each other improves the clamping effect and also ensures the clamping force.

[0026] The clamp support includes a first clamp support 6 and a second clamp support 8, which are cross arranged, the bottom of the cross center position of the clamp support is provided with a rotating shaft connected with the swing seat 3, and the swing seat 3 is further provided with a rotary platform 12 connected with the rotating shaft of the clamp support, so that the clamp support can rotate stably on the swing seat 3.

[0027] The height of the rotating lead screw in the first clamp support 6 is higher than that in the second clamp support 8; the rotation between the rotating lead screws 4 in the cross arranged clamp supports can be ensured not to be affected, so that the smooth operation of the whole mechanical device is ensured. The adjacent cross extended parts of the clamp supports are fixed through connecting rods, so that the stability of the whole device is ensured, and a speed reducer for adjusting the rotating speed of the transmission lead screw 4 is further arranged between the first motor 7 and the transmission lead screw 4, which is used for limiting the rotating speed of the transmission lead screw 4 and the moving speed of the nut seat 5 on the transmission lead screw 4, so as to ensure the stability and accuracy of the whole transmission system.

[0028] The working principle of the utility model is as follows:

[0029] The transmission lead screw 4 in the clamp assembly is driven to rotate through the first motor 7, so that the nut seats 5 at both ends of the same transmission lead screw move simultaneously, then the workpiece is clamped through the clamping jaw 11 on the nut seat 5, the stability and accuracy in the machining process are ensured, the action of the positioner and the clamp can be accurately controlled through the driving of the motor, the manual intervention of the operator for clamp adjustment is reduced, the manual operation error is avoided, the manual operation is reduced, and the production efficiency is improved.

[0030] Although the specific embodiments of the present disclosure are described above with reference to the drawings, the present disclosure is not limited to the above description, and various modifications or changes can be made on the basis of the technical solutions of the present disclosure without creative labor, which are still within the protection scope of the present disclosure.
