Embodiment Construction
[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0038] Please refer to Figure 6 and Figure 7 , the following will first introduce the fixed sleeve 40 that needs to be press-fitted. The fixed sleeve 40 includes a ring 41 and flanges 42 arranged on both sides of the ring 41. On the automobile transmission shaft and the input shaft of the rear axle, the convex edge 42 on one side is aligned with the arc surface on the automobile transmission shaft, and the convex edge 42 on the other side is aligned with the arc surface on the rear axle input shaft; When installing, riveti...

The invention discloses a press fitting tool used for riveting a fixing sleeve. The press fitting tool comprises a fixed clamping arm, an operation rod and a movable clamping arm; the fixed clamping arm comprises an arc section, a vertical section and a connection section; one end of the arc section and one end of the connection section are fixedly connected with the two ends of the vertical section separately; the other end of the arc section and the other end of the connection section extend towards the same side of the vertical section; one end of the operation rod is rotationally connectedto the junction of the connection section and the vertical section, and the other end of the operation rod and the connection section extend towards the same direction; the operation rod is providedwith an axial moving groove; the movable clamping arm comprises a body section and a guide column; one end of the guide column is fixedly connected with the body section, and the other end of the guide column penetrates through the connection section to be connected to the axial moving groove; and the operation rod can drive the movable clamping arm to move, so that the body section and the arc section are matched to press the fixing sleeve. The fixed clamping arm and the movable clamping arm are matched to finish riveting of the fixing sleeve, the fixing sleeve is riveted within the limited space, the assembly difficulty is reduced, and the assembly efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of machinery, in particular to a pressing tool for riveting a fixing sleeve. Background technique [0002] When the automobile drive shaft is connected to the input shaft of the rear axle, the flange and the bolt and nut assembly are generally used to connect. However, because the flange and the bolt and nut assembly need to be connected by four sets of bolts and nuts, the structure is complicated and the production process is difficult. The cost is high, and the assembly is time-consuming and labor-intensive. At the same time, due to the circumferential shape of the flange and the protruding bolt and nut assembly with the high-speed rotation of the automobile drive shaft, large noise will be generated, thereby reducing the transmission efficiency. [0003] In order to overcome the above-mentioned shortcomings, a structure was invented to connect the end of the universal joint yoke and the connection plate o...
