Specific Embodiments

[0015] Embodiment 1

[0016] As Figures 1 to 4As shown in the figure, the utility model discloses a positioner for kart frame welding, which includes a base 1, a backing plate 2, a reducer panel 3, a slewing bearing housing 4, a main box body 5, an arc shielding plate 6, an outer connecting flange 7, a two-axis bracket 8, a positioner base plate 9, a positioner box body 10, a positioner motor 11, a tailstock flange 12, a positioner motor connecting flange 13, an L-shaped plate 14, an outer frame 15, and an inner frame 16. A backing plate 2 is installed on the lower side of the foot posts of the base 1, and a reducer panel 3 is installed on the upper surface. The slewing bearing housing 4 is installed above the reducer panel 3. The main box body 5 is installed at the center of the upper side of the slewing bearing housing 4, and outer connecting flanges 7 are installed at the center of both left and right side surfaces. The arc shielding plate 6 is installed at the center of the main box body 5. The two-axis bracket 8 is installed on the outer connecting flange 7, and a positioner base plate 9 is installed at each of the front and rear ends of the outer side surface. The positioner box body 10 is installed on the positioner base plate 9. Positioner motors 11 are installed in the positioner box body 10 at the left rear and right front, and positioner motor connecting flanges 13 are assembled on their motor shafts. Rotating shafts are assembled in the positioner box body 10 at the left front and right rear. After the rotating shafts extend out of the positioner box body 10, tailstock flanges 12 are installed at their ends. The L-shaped plate 14 is installed on the positioner motor connecting flange 13 and the tailstock flange 12. The two ends of the outer frame 15 are respectively fixedly installed on the L-shaped plate 14. The inner frame 16 is welded and fixed inside the outer frame 15. A rotating motor is assembled inside the base 1, which can drive the main box body 5 to rotate. Two groups of rotating motors are assembled inside the main box body 5 to drive the two-axis bracket 8 to rotate, and cooperate with the positioner motor 11 to rotate. Each tooling realizes three-degree-of-freedom rotation, thus meeting the requirements of the special welding posture of the robot. The length of the arc shielding plate 6 is greater than the length of the two-axis bracket 8, and the height is greater than twice the height of the two-axis bracket 8. The two sides are completely isolated by the arc shielding plate 6, and the work on one side is not affected when welding on the other side.

[0017] Working principle of the utility model: When the utility model is in use, the outer frames 15 and inner frames 16 on the left and right sides are the frame fixing stations, which are symmetrically arranged on both sides and are isolated by the arc shielding plate 6. After the frame is fixed on the inner frame 16, the welding robot can be controlled to weld the frame according to the welding process. If the welding robot needs to weld in a special posture, the positioner motor 11, the rotating motors inside the main box body 5, and the rotating motor inside the base 1 can be controlled to rotate to adjust the frame to an appropriate welding angle. When the welding robot is working, the operator can carry out the frame fixing work on the other side station. After the welding robot finishes welding and rotates to the other side, the operator can disassemble the welded frame and replace it with a new frame for installation and fixing.

[0018] The components not described in detail in this article are prior art.

[0019] Although the specific embodiments of the present utility model have been described in detail above, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present utility model, and modifications or deformations that do not involve creative labor are still within the protection scope of the present utility model.
