Abstract

The utility model discloses a buffering and guiding mechanism of an electromagnetism riveter. The buffering and guiding mechanism of the electromagnetism riveter is used for solving the technical problem of big mechanical impact of an existing handheld electromagnetism riveter. The buffering and guiding mechanism of the electromagnetism riveter comprises a buffering mechanism and two guiding mechanisms, wherein the buffering mechanism is arranged above a mass block (1), the two guiding mechanisms are arranged below the mass block (1), and the buffering mechanism and the guiding mechanisms are distributed in a isosceles triangle mode. In the buffering mechanism, a shack absorber spring (4) and a buffering device (3) are combined. In each guiding mechanism, two guiding shafts (14) are matched with a linear bearing (13) and a guiding shaft spring (10) to enable relative sliding between the guiding shafts (14) and the mass block (1) to be achieved. As the buffering mechanism and the two guiding mechanism are adopted and the shock absorbing spring and the buffering device are combined in the buffering mechanism, mechanical impact of the handheld electromagnetism riveter is reduced. As the two guiding shafts are matched with the linear bearing and the guiding shaft spring in each guiding mechanism, guiding of the mass block is achieved.
