FIG. 2 is a schematic diagram of another embodiment of the present invention;

labeled as: the device comprises a lower supporting block 1, an upper pressing block 2, a lower arc groove 11, a rivet head placing groove 12, an upper arc groove 21, a rivet head forming groove 22 and a clamping device 3.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, the auxiliary tool for riveting rivets on a hollow tubular part comprises a lower supporting block 1 and an upper pressing block 2 arranged on the upper side of the lower supporting block 1, wherein the side surfaces of the upper pressing block 2 and the lower supporting block 1 corresponding to each other are respectively provided with an upper arc groove 21 and a lower arc groove 11, the lower arc groove 11 is provided with a rivet head placing groove 12, and the upper arc groove 21 is provided with a rivet heading forming groove 22 corresponding to the rivet head placing groove 12.

The riveting process by using the auxiliary tool for riveting the rivet on the hollow tubular part comprises the following steps: fixing the lower supporting block 1, placing the hollow tubular part with the rivet in the lower arc groove 11, and fixing the rivet head of the rivet in the rivet head placing groove 12; then, the upper arc groove 21 of the upper pressing block 2 and the hollow tubular part are correspondingly placed on the upper side of the lower supporting block 1, and the end of the rivet is embedded into the rivet heading forming groove 22; and finally, impacting the upper pressing block 2 by using a riveter to enable the upper pressing block 2 to move towards the lower supporting block 1, further extruding the end of the rivet by using the rivet heading forming groove 22 to form a rivet heading, and then taking down the hollow tubular part riveted with the rivet.

The corresponding side surfaces of the upper pressing block 2 and the lower pressing block 1 are usually matched, and can be a plane, a curved surface or other irregular surfaces as long as mutual interference is not generated; the upper arc groove 21 and the lower arc groove 11 are used for clamping and fixing the hollow tubular part, and the upper arc groove 21 and the lower arc groove 11 can be matched with the outer wall of the hollow tubular part due to the arc-shaped structures, so that the hollow tubular part is basically not damaged in the riveting process.

Preferably, as shown in fig. 1 again, the lower support block 1 and the upper pressing block 2 can be attached together, and after the lower support block 1 and the upper pressing block 2 are attached together, the lower arc groove 11 and the upper arc groove 21 together enclose a cylindrical hole which can be adapted to the hollow tubular part. The matching effect of the lower arc groove 11 and the upper arc groove 21 of the structure with the hollow tubular part is optimal, and the hollow tubular part is not damaged completely in the riveting process of the rivet.

Specifically, the cross sections of the lower arc groove 11 and the upper arc groove 21 are both semicircular.

The rivet head placing groove 12 is used for positioning and fixing a rivet to be riveted, can be of various structures, and is generally matched with a rivet head to be riveted so as to further improve the positioning and fixing effect of the rivet; the rivet head retaining groove 12 is generally hemispherical in configuration.

The upset rivet forming slot 22 is used to form the rivet head into an upset rivet which may be of various configurations, for example: conical, hemispherical, cylindrical, etc.

As a preferred embodiment of the present invention, as shown in fig. 2, the auxiliary tool for riveting rivet on the hollow tubular part further includes a clamping device 3 for clamping the lower support block 1. With the aid of the clamping device, the lower supporting block 1 is effectively clamped and fixed by the clamping device 3 in the riveting process of riveting the rivet on the hollow tubular part, and then the subsequent riveting operation is carried out. The clamping device 3 may be of various kinds, preferably a bench vice.

Specifically, the auxiliary tool for riveting the rivet on the hollow tubular part further comprises a rivet gun. When the upper press 2 is impacted by the riveter, it is preferable to impact the upper press 2 directly above the rivet upset forming groove 22.
