A shock-absorbing tool for durability test

Abstract

The invention discloses an endurance test shock absorption tool which comprises an installation flat plate (1) and suspension column feet (10). Two side faces of the installation flat plate (1) are provided with through holes (4) respectively in the X direction and the Y direction. The through holes (4) vertically intersect to be of a crossed structure. Two balance screw rods (3) are arranged in the through holes (4) respectively. Locking nuts (5) are arranged at the two ends of each balance screw rod (3) respectively, the suspension column feet (10) are arranged at the four corners of the installation flat plate (1), and each suspension column foot (10) is composed of a pagoda-shaped spring (6), a sheath (7), a spring bottom seat (8) and a spring upper seat (9). The sheaths (7) are arranged outside the pagoda-shaped springs (6), the spring bottom seats (8) are arranged at the lower ends of the pagoda-shaped springs (6), and the spring upper seats (9) are arranged at the upper ends of the pagoda-shaped springs (6). The spring upper seats (9) are connected with the installation flat plate (1) which is provided with installation fixing screw holes (2). The endurance test shock absorption tool enables the center of gravity of an irregular structure to shift, and the irregular structure is balanced by adjusting the balance screw rod in the X direction and the balance screw rod in the Y direction, certain impact force and reaction force of the endurance test shock absorption tool body on a work table board can be eliminated, and the endurance test shock absorption tool is simple in structure, durable, and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of durability testing for product testing, in particular to a shock-absorbing frock for durability testing. Background technique [0002] The moving structure part of some small mechanical and electrical products needs to go through the movement durability test in the design and trial production process to verify whether the structure and the materials used meet the design requirements and meet the design life of the working conditions. During the test, a mounting plate is required. It is fixed for vibration or reciprocating durability test, and its size needs to be determined according to the product to be tested, so there is no ready-made purchase, and it needs to be customized or self-made. [0003] When the existing electromechanical products are subjected to durable vibration or reciprocating motion tests, the tested products are fixed in the central area of ​​the platform. Due to the irregular structur...

Problems solved by technology

[0003] When the existing electromechanical products are subjected to durable vibration or reciprocating motion tests, the tested products are fixed in the central area of ​​the platform. Due to the irregular structure of various products, the center of gravity shifts and the product body forms a certain impact force and reaction force on the work surface. question
