The invention provides a small-gear precise indexing simple riveting device. The device comprises a base, a shaft and a gear combination, wherein the base is placed in a positioning hole of a hand arbor press, the base is of a cylindrical structure, a through hole is arranged inside the base to penetrate an upper plane and a bottom surface, the shaft is arranged in the through hole of the base, acircular hole is formed in the center of an external gear, an internal gear is arranged in the circular hole, the gear combination is placed on the upper surface of the base, at the moment, the external gear is located on the upper plane of the base, the internal gear is located in the through hole of the base, one end of the internal gear is in contact with the shaft, the gear combination rotatesby taking the shaft as a rotating shaft, the base is further provided with a reed which is used for stopping rotation of the gear combination, a pressing head is arranged at the upper part of the hand arbor press, a handle is pulled to carry out riveting, after one point of the external gear or one point of the internal gear is riveted, the gear combination is rotated, and when the reed is used for stopping the rotation of the gear combination again, the next point can be riveted until all riveting points of the gear combination are riveted.
Description
technical field [0001] The invention belongs to the technical field of mechanical assembly, and is particularly suitable for the precision indexing technology of combined riveting of gears. Background technique [0002] Usually in mechanical assembly, some gear combination riveting does not use indexing technology. It connects the upper and lower templates through several guide columns. The upper template is equipped with several pressure heads, and the gear combination is installed on the lower template. To achieve riveting, theoretically speaking, it is difficult for this method to rivet each riveting point well at the same time, and the riveting device has many parts and complex structure. Some gear combination riveting is driven by the driving mechanism to rotate the gear combination. When the rod teeth and the gear teeth mesh, the riveting push rod moves upwards, and the riveting is performed by falling down by its own gravity. The device has a driving mechanism and a t...
