Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model relates to a riveting tool, as shown in fig. 1, including end cover 1, the sliding connection has stop device in 1 inside central point of end cover, and stop device includes gag lever post 4 along the 1 inside vertical installation of end cover, and 4 tip joints of gag lever post have spring 3, and 3 vertical being connected with compact heap 2 of spring. The inner wall of the end cover 1 is provided with a riveting end, and the section of the riveting end is a triangular pyramid surface. The riveting end is matched with the limiting device for riveting. The riveting device is characterized by further comprising a lower support 5, wherein a second part 6 is fixed on the lower support 5, the second part 6 is coaxially connected with a first part 7, the diameter of the first part 7 is larger than that of the second part 6, the surface of the first part 7 is in contact with the pressing block 2, and the edge of the first part 7 is in contact with the riveting end. The top of end cover 1 is provided with installed part 8, and installed part 8 rigid coupling has pneumatic press. The mounting member 8 is a mounting bar.

The utility model relates to a riveting tool's working process is, fix part two 6 on lower bearing 5, place part two 6 upper surfaces with part one 7 is coaxial, then detain end cover 1 on part one 7, at this moment, compact heap 2 and part one 7 upper surface contact, it does not let its activity to push down part one during riveting, can guarantee that part one and part two reliably paste closely, simultaneously, part one 7 contacts with the riveting end of end cover 1, then pneumatic press has been installed on the installed part 8 on end cover 1 top; and then, starting the pneumatic press, descending the pressure end of the pneumatic press, descending the end cover 1 along with the pressure end of the pneumatic press, pressing the part I7 to the part II 6 under the compression of the riveting end with the end surface structure of a triangular pyramid surface, wherein the diameter of the part I7 is larger than that of the part II 6, so that the edge of the part I7 deforms towards the outer surface direction of the part II 6 under the action of pressure, and the part I7 is pressed to the outer surface of the part II 6, and finally the part I7 and the part II 6 are riveted together. In the process, the limiting device ensures the stability of the first part and the second part in the riveting process.
