Problems solved by technology

Solid rivets have large batches, high sampling ratio for riveting tests, low efficiency of riveting tests, and low efficiency of dismantling upset samples by drilling, punching and other mechanical processing methods after riveting
But so far, there is no riveting test fixture that can be riveted in batches and can be disassembled in batches, which leads to poor stability of riveting tests, can not avoid twisting and forging skew caused by upsetting, low efficiency and high labor intensity

Abstract

The invention discloses a combined riveting test clamp easy to rivet and disassemble, which is characterized in that: a pressing block (1) is inserted into the upper end of an outer sleeve (2); the lower end of the outer sleeve (2) is connected with a base (5) through a bolt; an inner core (4) is placed on the base (5); the lower end of the inner core (4) is inserted into the lower end in the outer sleeve (2); the middles of ejector rods (6) are inserted into the inner core (4) respectively; and the two ends of the inner core (4) are inserted into a riveting plate (3) and the base (5) respectively. According to the invention, the stability of a de-riveting test is good, the conditions of twisting and inclined forging during upsetting are avoided, the efficiency is high, the labor intensity is low, and the test efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a combined riveting test jig which is easy to rivet and disassemble. Background technique [0002] Solid rivets are widely used in the mechanical connection of aircraft skins and other parts. The riveting function is realized by mechanically deforming the tail of the solid rivet to produce an upset head. In order to prevent the riveting performance of solid rivets or rivet materials from not meeting the requirements of technical standards, and to prevent quality defects such as cracks in the head during the riveting process, riveting tests must be carried out during the production process and before use. Solid rivets have a large batch size, a high sampling ratio for riveting tests, low efficiency for riveting tests, and low efficiency for dismantling upset samples by drilling, punching and other mechanical processing methods after riveting. But so far, there is no...
