[0002] Since the automobile frame is assembled from multiple automobile brackets of different shapes (such as automobile rear frame, automobile front frame, automobile side door bracket, etc.), and these automobile brackets are generally made of aluminum alloy, in order to improve processing efficiency, after the automobile bracket is produced, it is necessary to die-cast steel nuts to facilitate later installation. With the continuous development of the automobile industry, the requirements for the automobile manufacturing industry are also getting higher and higher. Therefore, automobile bracket riveting equipment is available. However, when the existing automobile bracket riveting equipment clamps the automobile bracket to the riveting machine, a robot is generally used to clamp an automobile bracket and then transport it to a riveting machine.

[0035] The specific working principle of this structure is as follows: the structure is installed on the conveyor belt of the automobile riveting equipment (the existing conveyor belt is two conveyor belts distributed front and back, and the automobile bracket is set on the two conveyor belts with a gap in the middle, which will not affect the insertion of the flip clamp under the flip assembly), and the throttle pipe on the side of the pneumatic turntable 1 2 is connected to the gas generator. Later, the pneumatic turntable 2 404 is connected to the gas generator through the air pipe inserted into the mechanical arm 2 402. The pneumatic turntable 1 2 rotates, driving the upper motor seat to rotate 3360 degrees, which is convenient for the lower part of the loading clamp seat 5. The automobile bracket is transported to the press riveting, and at the same time, the motor 1 21 can adjust the pitch angle of the loading clamp 5 in a wide range. When the automobile bracket is transported on the conveyor belt of the automobile press riveting equipment, the loading clamp 5 is rotated to the conveyor belt under the action of the pneumatic turntable 1 2. In the initial state, the flip clamp 2 111, the flip clamp 1 101 and the flip clamp 3 222 are all set downward, which does not affect the contact between the front suction plate 6, the center pressure plate 1 7, the center pressure plate 2 8 and the rear suction plate 9 and the upper surface of the automobile bracket. When the motor 1 21 works, the front suction plate 6, the center pressure plate 1 7, the center pressure plate 2 8 and the rear suction plate 9 are After the suction plate 9 moves down, it contacts the upper surface of the car bracket, driving the flip cylinder 2 112, the flip cylinder 3 221 and the flip cylinder 1 102 to work, and the flip clamp 2 111, the flip clamp 1 101 and the flip clamp 3 222 are rotated 90 degrees and are located below the car bracket. Cooperating with the front suction plate 6, the center pressure plate 1 7, the center pressure plate 2 8 and the rear suction plate 9 above, the product is evenly pressed together, and then the output shaft of the motor 1 21 is flipped, the car bracket is clamped and transported to the press riveting for press riveting nuts. In this structure, two symmetrical grippers are set below the feeding clamp 5. The component can clamp two automobile brackets at one time, so two riveting machines with the same structure can be set up. Under the action of the rotation of the pneumatic turntable 1 / 2, the two clamped products are placed on the riveting machine, so that the two riveting machines can work at the same time, further improving the work efficiency. Moreover, this structure adopts a four-point clamping method to clamp the product, ensuring that the force is evenly distributed to the four points, and avoiding the problem of product deformation and damage caused by the clamping force being applied to one point and the clamping force being too large, and the clamping force is dispersed, so the force does not need to be very large.
