specific Embodiment approach 1

[0011] Specific implementation mode one: combine Figure 1 to Figure 8 Explain, the riveting method of a hollow rivet and flat head screw described in this embodiment includes the following steps:

[0012] Step 1: Assembling the hollow rivet 5: First, fix the support seat 1 on the workbench, the lower end surface of the support seat 1 is a plane, the upper end surface of the support seat 1 is an arc surface, and the arc surface of the upper end surface of the support seat 1 is in line with the The arc of the cover plate 4 is the same, install the small end of the hollow rivet 5 vertically upwards into the mounting hole on the cover plate 4, and then place the cover plate 4 after the hollow rivet 5 is assembled on the upper end surface of the support seat 1 ;

[0013] Step 2: Flange: Flange pin 2 is a stepped shaft, and the position between the shafts of flange pin 2 is provided with a conical surface. The diameter of the small end of flange pin 2 is smaller than the inner dia...

specific Embodiment approach 2

[0017] Specific implementation mode two: combination Figure 1 to Figure 8 To illustrate, in step 1 and step 3 of this embodiment, a rubber pad 1-1 is laid on the upper surface of the support base 1, and a groove 1-1-1 is provided in the middle of the rubber pad 1-1. Other method steps are the same as those in the first embodiment.

[0018] The rubber pad 1-1 acts as a buffer to prevent the surface of the cover plate 4 and the flat head screw 5 from being bumped during riveting, and the nut of the flat head screw 5 is placed in the groove 1-1-1 to prevent the flat The round head screw 5 interferes with the rubber pad 1-1, which is inconvenient for positioning.

specific Embodiment approach 3

[0019] Specific implementation mode three: combination Figure 1 to Figure 8 It should be noted that in step 1 and step 3 of the present embodiment, the thickness of the rubber pad 1-1 is 1mm-3mm, and the depth of the groove 1-1-1 is 0.5mm-1.5mm. Other method steps are the same as in the second embodiment.

Abstract

The invention belongs to the field of machining, and particularly relates to a riveting method of a hollow rivet and an oval head screw. In order to solve the problems of low working efficiency and the high rejection rate in an existing riveting process, the riveting method of the hollow rivet and the oval head screw comprises steps as follows: step one, assembly of the hollow rivet; step two, flanging; step three, assembly of the oval head screw; step four, riveting. The method is mainly used for riveting the hollow rivet with a cover plate and the oval head screw with the cover plate.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a riveting method for a hollow rivet and an oblate head screw. Background technique [0002] Hollow rivets and oblate head screws riveted on the cover plate are assembled in the product, and its loading and unloading speed can improve the efficiency by about 80% to 90% compared with the method of bolt connection, and is widely used. The assembly needs to rivet hollow rivets and flat head screws on the cover plate, and ensure that the riveted flat head screws can rotate flexibly. When riveting, it is necessary to use special tools to rivet and assemble the hollow rivets, oblate head screws and cover plates together for riveting. In the existing riveting process, the flat head screw is often damaged due to the action of external force, and the flat head screw will be deformed after riveting, so that the rotation of the flat head screw is restricted, the scrap rate is high, and...
