Rotary booster energy-absorbing cylinder fixing device

Abstract

The invention discloses a rotating force-increasing energy absorption barrel fixing device. The rotating force-increasing energy absorption barrel fixing device mainly comprises a rotary rod 1, a fixed base plate 2, a rotary disk 3, tensioning sheets 4, rotary pins 5, first connecting rods 6.1, second connecting rods 6.2, sliding blocks 7, guide rods 8, a lead screw shaft 9 and a rotary sheet 10. One end of the lead screw shaft 9 is fixedly connected with the fixed base plate 2. The rotary disk 3 is rotationally connected with the lead screw shaft 9. The rotary disk 3 rotates to drive the guide rods 8 and the rotary sheet 10 to rotate so as to drive the sliding blocks 7 to rotate and slide along the lead screw shaft 9. The tensioning sheets 4 are pushed to do radial motion through the first connecting rods 6.1 and the second connecting rods 6.2, and then an energy absorption barrel is tensioned. By adopting the rotating force-increasing energy absorption barrel fixing device, the problems of site and equipment constrains, low working efficiency and large workload caused by traditional energy absorption barrel welding and fixing methods are solved. The simple energy absorption barrel fixing device provided by the invention is simple in structure, high in work reliability, capable of being utilized repeatedly and particularly suitable for fixation of various energy absorption barrels of different specifications.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a fixing device for a rotating booster type energy-absorbing cylinder. Background technique [0002] At present, in the crash test of the trolley, the energy-absorbing cylinder is mainly fixed by welding, but the welding work efficiency is low, and after the collision is completed, the energy-absorbing cylinder needs to be cut to remove it, which cannot be reused. Due to the need for welding equipment, the use of traditional welding methods will be greatly affected by the site and equipment. [0003] Patent 201510545865.0 discloses an energy-absorbing tube fixing device to solve the above problems, but there are still some defects, such as 1. When the energy-absorbing tube is placed on the device, a hexagonal wrench needs to be inserted from the front end of the energy-absorbing tube for alignment The hexagonal hole, because sometimes the energy-absorbing cylinder may be rel...
