[0002] In the production process of the automobile, many parts processing are involved, and most of the parts processing are inconvenient to be integrally formed due to structural limitations, and usually need to be welded by using a welding process, so as to form a complete part. In the welding process, in order to avoid misplacement of the two parts to be welded, which leads to welding failure, the two parts to be welded are usually aligned on the platform, and the end parts away from each other are fixed by using a clamp, so as to avoid the influence of the clamp on the welding arm. After the welding is completed, the welded part needs to be taken off from the welding clamp, so as to facilitate the installation of the two parts to be welded subsequently.

[0003] At present, when the part is taken out, if the platform is directly lifted to eject the part, if the operator cannot take the part away in time when the part is ejected, the part will fall between the two clamps, which affects the fixation of the two parts on the clamp subsequently. If a mechanical arm is used to take away the completed part, the cost of the whole welding equipment will be increased, and due to the limitation of the installation space, the mechanical arm for taking away the part will interfere with the welding arm and the clamp.

[0004] Based on the above reasons, the utility model provides a clamp overturning unloading structure, which can automatically move the welded part away from the position of the clamp after the part is welded, so as to avoid affecting the installation of the subsequent parts to be welded on the clamp.

[0019] Example:

[0020] The utility model provides a kind of jig overturns blanking structure, including upper and lower arrangement platform 1 and base 2, base 2 is arranged with stroke limiting rod 3 and cylinder 4 in front and back direction, and the sliding hole is provided on base 2, and stroke limiting rod 3 is slidably arranged in sliding hole, and the upper limit ring 5 and lower limit ring 6 are respectively provided above and below sliding hole of stroke limiting rod 3, and the upper end of stroke limiting rod 3 is connected with the vertical rotation of the lower side of platform 1, and cylinder 4 is installed vertically upwards, and the output shaft of cylinder 4 is movably connected with the lower side of platform 1.When welding, the welding position of two components to be welded is placed in alignment on platform 1, and two components to be welded are clamped by jig, then welding is carried out, after welding is completed, jig releases the part after welding, and cylinder 4 is started, and cylinder 4 drives platform 1 to move upwards, and platform 1 drives stroke limiting rod 3 to move upwards, under the action of upper and lower limit rings 6 of stroke limiting rod 3, after moving a distance, stroke limiting rod 3 cannot continue to move upwards, and the front of fixed platform 1 cannot continue to move upwards, so that cylinder 4 continues to push to move upwards will make the rear of platform 1 overturn to be inclined, so that the part will slide to the front of platform 1, and move away from the top of jig.After the part slides away, cylinder 4 is retracted, drives platform 1 and stroke limiting rod 3 to move downwards and reset, so as to process subsequent components to be welded.

[0021] The lower side of platform 1 is vertically provided with connecting plate 7, the upper end of stroke limiting rod 3 is installed first connecting sheet 8, the first rotating hole that is provided with through left and right sides is set on connecting plate 7, the second rotating hole 9 that is provided with through left and right sides is set on first connecting sheet 8, and first rotating hole and second rotating hole 9 are rotatably connected by rotating shaft 10.Such setting, after stroke limiting rod 3 moves upwards to limit distance, platform 1 is under the action of cylinder 4, so that connecting plate 7 and first connecting sheet 8 are rotated by rotating shaft 10, so that the rear of platform 1 is tilted and tilted upwards.

[0022] The upper end of the output shaft of the cylinder 4 is horizontally provided with a push plate 11, and the upper side of the front end of the push plate 11 is vertically provided with a second connecting piece 12. The upper side of the push plate 11 is vertically provided with a first hanging piece 13 behind the second connecting piece 12. The first hanging piece 13 is provided with a first hanging hole 14. The lower side of the platform 1 is provided with a second hanging piece 15. The second hanging piece 15 is provided with a second hanging hole 16 behind the second connecting piece 12. The first hanging hole 14 and the second hanging hole 16 are connected by a spring 17. The upper end of the second connecting piece 12 is in top contact with the lower side of the second hanging piece 15. In this way, when the output shaft of the cylinder 4 moves upward, the push plate 11 and the second connecting piece 12 are driven to push the platform 1 upward, and the spring 17 and the stroke limiting rod 3 pull the platform 1 on both sides of the second connecting piece 12. This can make the platform 1 move upward more stably. When the lower limiting ring 6 of the stroke limiting rod 3 is attached to the lower end of the sliding hole, the stroke limiting rod 3 cannot continue to move upward, the cylinder 4 drives the platform 1 to rotate around the rotating shaft 10, and the spring 17 will be stretched during the rotation of the platform 1. After the cylinder 4 is stretched to the position, it starts to retract. During the descent of the platform 1, the elastic potential energy generated by the stretching of the spring 17 will gradually pull the platform 1 back to the horizontal position. The entire process can first move the welded parts vertically upward away from the position of the clamp, and then move the parts away from the position above the clamp through the inclined platform 1, avoiding affecting the installation of the subsequent parts to be machined to the clamp.

By arranging the upper threaded column, the upper limiting ring 5 can be stably installed. The upper limiting ring 5 can prevent the stroke limiting rod 3 from continuing to move downward, thereby providing stable support force to the platform 1.

[0025] The base 2 comprises a bottom plate 19, a vertical plate 20 and a top plate 21, the lower end of the vertical plate 20 is installed on the upper side of the bottom plate 19, the top plate 21 is installed on the front side of the top end of the vertical plate 20, the connection between the vertical plate 20 and the bottom plate 19 and the top plate 21 is provided with a reinforced support plate 22, a sliding hole is provided through the top plate 21, and the air cylinder 4 is installed on the rear side of the vertical plate 20.
