Detailed Description

The invention will be further described with reference to the accompanying drawings and the detailed description below:

as shown in fig. 1 and 2, a bearing sleeve pressing device includes a rivet joint 10 and a bottom plate 30, and is characterized in that:

as shown in fig. 1, the rivet head 10 includes a main body 11, an upper end of the main body 11 is fixed on a press 20, and a lower end of the main body 11 is provided with a cylindrical boss 12; the radial dimension of the boss 12 is smaller than the radial dimension of the body 11;

as shown in fig. 2, six radially and uniformly distributed press-riveting points 13 are arranged at the corner where the boss 12 is connected with the main body 11;

as shown in fig. 2, the top of the bottom plate 30 is provided with a fixed main support shaft 32 and five auxiliary support shafts 31 (the invention is illustrated by taking one main support shaft 32 and five auxiliary support shafts 31 as examples, which can be increased or decreased according to the shape of the workpiece 60); the main supporting shaft 32 is coaxial with the rivet joint 10 and is in contact fit with the back of a bearing hole of the workpiece 60; in operation, the main support shaft 32 is in contact fit with the back of the bearing hole of the workpiece 60 to effectively prevent the main body of the workpiece 60 from deforming and breaking;
