These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] Figure 1 This is a first-view structural schematic diagram of the present invention; Figure 2 This is a structural schematic diagram of the present invention from a second perspective.

[0020] An alternating feeding riveting machine includes a base 1, an upper die 2, a lower die 3, and an upper die lifting power cylinder 4. The upper die lifting power cylinder 4 is mounted on the base 1, and its piston rod is connected to the upper die 2. The lower die 3 is located directly below the upper die 2. A gripper lifting mechanism 5 is mounted on the base 1, and a gripper rotating mechanism 6 is connected to the lifting part of the gripper lifting mechanism 5. A connecting plate is fixed on the output shaft of the gripper rotating mechanism 6, and grippers 7 are mounted on both ends of the connecting plate. The lower die 3 is slidably connected to a horizontal straight rail on the base 1. A lower die horizontal moving mechanism 8 is mounted on the base 1, and its moving part is connected to the lower die 3. The lower die 3 has a positioning groove for mating with the product.

[0021] The gripper lifting mechanism 5 is a linear cylinder. The cylinder body of the linear cylinder is fixed on the machine base 1, and the piston rod of the linear cylinder is fixed on the cylinder body of the gripper rotating mechanism 6.

[0022] The extension and retraction of the piston rod of the gripper lifting mechanism 5 can drive the two grippers 7 to rise and fall synchronously.

[0023] The gripper rotation mechanism 6 is a rotary cylinder, and the output shaft of the rotary cylinder is fixed to the connecting plate. The gripper rotation mechanism 6 can drive the connecting plate to rotate in the horizontal plane, thereby allowing the front and rear positions of the two grippers 7 to be adjusted at any time.

[0024] The lower mold horizontal moving mechanism 8 includes a single-rod cylinder and a connecting block. The cylinder body of the single-rod cylinder is connected to the bottom of the machine base 1, and the piston rod of the single-rod cylinder is connected to the bottom of the lower mold 3 through the connecting block.

[0025] The extension and retraction of the piston rod of the single-rod cylinder can drive the lower mold 3 to move along the horizontal straight rail into and out of the base 1.

[0026] A damping rod 9 is installed at the front end of the base 1 to limit the lower die 3. The damping rod 9 can buffer and block the outward movement of the lower die 3.

[0027] Several guide rods 10 are vertically connected to the top of the upper mold 2, and the guide rods 10 pass through guide holes on the top plate of the base 1. The raising and lowering of the upper mold 2 will cause the guide rods 10 to move along the guide holes, thereby maintaining the stability of the movement of the upper mold 2.

[0028] Several sliding rods are slidably connected to the bottom of the upper mold 2. A pad 11 is provided at the bottom end of the sliding rod, and a spring 12 is provided between the pad 11 and the upper mold 2. When the upper mold 2 moves down, the pad 11 presses against the bottom plate of the machine base 1, and the spring 12 provides cushioning to prevent the product from making hard contact with the upper mold 2.

[0029] The working method of this application is as follows: the lower mold 3, carrying the riveted product, moves out of the machine base 1. At this time, the gripper lifting mechanism 5 drives the two grippers 7 to descend synchronously. The rear gripper 7 clamps the product on the lower mold 3, while the front gripper 7 clamps the unriveted product in front. Then, the two grippers 7 move upward synchronously, and the gripper rotation mechanism 6 drives the two grippers 7 to switch positions and move downward again. In this way, the unriveted product can be placed on the lower mold 3 at the same time, and the riveted product can be placed in the front position for the operator to remove. Finally, the lower mold 3 moves horizontally to directly below the upper mold 2 to begin riveting.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
