Slipknot screw type rapid combined circular quality system with guide rod

Abstract

The invention aims to overcome the defects of high manufacturing cost and inconvenience in use of a whole mass block in a buffer material vibration transmission characteristic test system, repeated disassembly of bolts in a combined mass system, low combination efficiency of nuts, and no horizontal limiting function of the mass system with a guide device. A slipknot screw type rapid combined circular quality system with a guide rod is developed, and the vibration transmission characteristic test of the buffer material is carried out in cooperation with a table board fixing device. The bottom face of the mass system is of a circular structure and is rapidly locked through a weight type combination and a slipknot screw combination, and the top of the mass system is provided with a single-rod guide device. Compared with a combined mass block, when the mass is adjusted, the weights of the mass system can be quickly locked and combined only by adjusting the compression nut in a small range, and the mass system is of a rigid structure after being locked; and meanwhile, the mass system is provided with a vertical movement single-rod guide device, and after the vertical movement single-rod guide device is matched with the fixing device, the mass system can be prevented from moving in the horizontal direction in the vibration process.

Description

technical field [0001] The invention relates to the field of material mechanical performance testing, mainly relates to the vibration transfer characteristic test of buffer materials, and in particular to a slipknot screw type fast combined circular mass system with a guide rod for the vibration transfer test of buffer materials. Background technique [0002] The vibration transfer characteristic of the cushioning packaging material is one of the important performances required for the protection of transport packaging. The transfer rate of the system is obtained through the vibration transfer characteristic experiment, that is, the dimensionless ratio of the response amplitude to the excitation amplitude of the system in the steady-state forced vibration. The vibration transmission characteristic test system of packaging materials is composed of cushioning materials and mass blocks. Acceleration sensors are installed on the vibration table and mass blocks respectively during...

Problems solved by technology

[0007] The quality system required for testing the vibration transfer characteristics of cushioning materials has the disadvantages of high production cost and inconvenient use of the monolithic mass block, and the combined quality system requires repeated disassembly of bolts and low efficiency of nut assembly. At the same time, there is no guide device and quality system. Insufficient of the limit function in the horizontal direction, the present invention has developed a slip-knot screw type fast combined circular quality system with guide rods, which can be used to test the vibration transmission characteristics of the cushioning material with the table fixing device
