[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0016] See also Figure 1-4The utility model provides a technical solution: a riveting machine for the production of large floor parts of automobiles, comprising a base 1, a column 2 is fixedly arranged on the base 1, an annular turntable 3 is rotatably arranged on the upper surface of the base 1 outside the column 2, a plurality of die holders 4 are evenly arranged on the turntable 3, and the plurality of die holders 4 can be placed on the riveted parts, a slide groove 5 is opened on one side of the column 2, a slider 6 is slidably arranged in the slide groove 5, a pressure head 7 is fixedly arranged at one end of the bottom of the slider 6, and the pressure head 7 is placed above the moving track of the plurality of die holders 4, and the turntable 3 rotates. The die base 4 with the riveted parts can be moved to the bottom of the pressure head 7, and the riveted parts in the die base 4 can be riveted by the pressure head 7. A telescopic rod 8 is fixedly provided above the column 2, and the telescopic end of the telescopic rod 8 is fixedly connected to the slider 6. A linkage mechanism connecting the slider 6 and the turntable 3 is provided in the base 1. When the slider 6 is reset from bottom to top, the turntable 3 can be rotated through the linkage mechanism, and its rotation angle is equal to the angle between the two adjacent die bases 4, so that the next die base 4 on the turntable 3 can be moved to the bottom of the pressure head 7 after each reset of the slider 6.

[0017] As an embodiment of the present utility model, the linkage mechanism includes a connecting rod 9 and a rotating shaft 11. The connecting rod 9 is fixedly connected to the slider 6. The rotating shaft 11 is rotatably set in the base 1. A rack 10 is fixedly set on one side of the bottom of the connecting rod 9. A ratchet assembly 12 is installed at one end of the rotating shaft 11. The ratchet assembly 12 is engaged with the rack 10. When the slider 6 descends, the torque will not be transmitted to the rotating shaft 11 through the ratchet assembly 12. When the slider 6 rises, the rotating shaft 11 can be driven to rotate through the ratchet assembly 12. A gear 13 is fixedly set at the other end of the rotating shaft 11, and a ring gear 14 is fixedly set on the lower surface of the turntable 3. The ring gear 14 is engaged with the gear 13. When the rotating shaft 11 rotates, the turntable 3 can be rotated on the base 1.

[0018] As an embodiment of the present invention, the ratchet assembly 12 includes an outer wheel body 12.1, an inner wheel body 12.2, and a pawl 12.3. The outer wheel body 12.1 is rotatably mounted on the rotating shaft 11. The outer surface of the outer wheel body 12.1 is engaged with the rack 10. When the rack 10 moves up and down, the outer wheel body 12.1 can be rotated. The inner wheel body 12.2 is fixedly mounted on the rotating shaft 11. The pawl 12.3 is hinged in the outer wheel body 12.1 and one end thereof abuts against the outer surface of the inner wheel body 12.2. One side of the pawl 12.3 is provided with a torsion spring 12.4 that can pull it toward the inner wheel body 12.2. When the connecting rod 9 moves downward, the outer wheel body 12.1 rotates to one side, and the pawl 12.3 cannot be stuck on the inner wheel body 12.2. At this time, the outer wheel body 12.1 is idling. When the connecting rod 9 moves upward, the outer wheel body 12.1 rotates to the other side, and the pawl 12.3 can be stuck on the inner wheel body 12.2, thereby realizing the power transmission between the outer wheel body 12.1 and the inner wheel body 12.2.

[0019] As an embodiment of the present invention, positioning cylinders 15 are fixedly provided on the inner sides of multiple mold bases 4 on the turntable 3, and positioning rods 16 matching the positioning cylinders 15 are fixedly provided under the slider 6. The bottom of the positioning rod 16 is a pointed structure, which is convenient for the positioning rod 16 to be inserted into the positioning cylinder 15. When the slider 6 descends and the pressure head 7 is not in contact with the riveted part, the positioning rod 16 can be inserted into the positioning cylinder 15 to fix the circumferential position of the turntable 3. At the same time, the pointed positioning rod 16 can play a guiding role, so that the mold base 4 can be directly below the pressure head 7, thereby improving the accuracy of the position of the mold base 4. When the slider 6 rises, the positioning rod 16 can be completely moved out of the positioning cylinder 15 before the rack 10 contacts the ratchet assembly 12 to complete the rotation of the turntable 3.

[0020] After riveting, the slide 6 moves upwards and resets. When the positioning rod 16 is completely removed from the positioning cylinder 15, the rack 10 contacts the outer wheel body 12.1. At this time, the outer wheel body 12.1 can transmit power to the inner wheel body 12.2 through the ratchet 12.3, thereby rotating the shaft 11, and the turntable 3 can be driven to rotate by the shaft 11, so that the next die base 4 moves to the bottom of the pressure head 7, and the slide 6 is lowered again for riveting, so that the riveted parts can be installed on other die bases 4 when the pressure head 7 is performing the riveting action, thereby improving production efficiency and eliminating the need for staff to put their hands under the pressure head 7.

[0021] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
