[0003] However, this type of riveting machine usually has the following defects. First, if the riveting size of the riveted parts is not large enough after the riveting, the transmission pressure force received by the rest of the parts is insufficient, and the riveting size has reached the upper limit and the rest of the parts It is still in a loose state; the other is that the rest of the parts are not fully assembled during assembly, and when the riveting is performed, the riveted parts should expand, so that the parts that are not assembled in place are stuck and cannot be compressed by the riveted parts If it is pressed in place, there will be a large gap between the parts, which will affect the performance of the product.

Embodiment Construction
[0031] In order to clearly illustrate the technical characteristics of this patent, the following describes this patent in detail through specific implementation methods and in conjunction with the accompanying drawings.
[0032] In this case, take the central shaft and end cover of the spin riveting tensioner as an example. The tensioner to be processed is as published by the National Bureau on February 6, 2013 called "Belt Tensioner for Engine Front Accessory Drive System". , and the Chinese utility model patent with the application number "201220373170.0" shows that before the riveting, there are gaps between the spring support sleeve, the support plate, the backing plate, the ferrule, and the central shaft sleeve. If the central shaft and the If the end cover (that is, the panel in this case), gaps are likely to appear between the above-mentioned components after screw riveting, which will affect product performance.
[0033] This case is as Figure 1-3 As shown, it inclu...

The invention discloses a special rack for a spin riveting machine, and relates to the field of auxiliary tools of spin riveting machines. The special rack for the spin riveting machine is exquisite in structure, convenient to use, high in working efficiency and good in machining effect. According to the technical scheme, the special rack comprises an equipment base 1, an equipment rack, a spin riveting assembly, a working table top 6, a lifting driving device, a pre-pressing assembly and a feeding assembly. The lifting driving device is connected between the working table top 6 and the equipment base 1 and is used for driving the working table top 6 to do reciprocating lifting motion. The pre-pressing assembly is connected to the working table top 6 and is used for pressing a workpiece before spin riveting and in the spin riveting process. The feeding assembly is slidably connected to the working table top 6, a workpiece mounting hole is formed in the feeding assembly and the feedingassembly is used for pushing the workpiece into the pre-pressing assembly or pulling the workpiece out of the pre-pressing assembly. According to the special rack, the production efficiency is guaranteed, and the spin riveting accuracy is guaranteed.
Description
technical field [0001] The invention relates to the field of auxiliary tooling for spin riveting machines, in particular to the improvement of a special stand for multi-part assembly spin riveting. Background technique [0002] Existing spin riveting machines usually use the motor in the equipment to drive the riveting head to rotate and press down, generating downward pressure on the riveted riveted, causing it to expand and produce a certain pressing force on other parts, and finally make the parts that need to be assembled fit together ; [0003] However, this type of riveting machine usually has the following defects. First, if the riveting size of the riveted parts is not large enough after the riveting, the transmission pressure force received by the rest of the parts is insufficient, and the riveting size has reached the upper limit and the rest of the parts It is still in a loose state; the other is that the rest of the parts are not fully assembled during assembly,...
