Problems solved by technology

[0004] The vibration testing machine tests the stability of the seat slide rail during the sliding process. The existing slide rail vibration testing machine has inaccurate positioning, which cannot guarantee the close fit between the slide rail workpiece and the tooling, and the calculation standard is not clear. Specifically test the detailed data of its vibration, and the test function is not complete at the same time, it can only test the vibration in a single direction, and the efficiency is not high

Abstract

The invention provides a vibration testing machine which is used for testing a workpiece. The workpiece comprises a sliding block and a sliding plate. The vibration testing machine comprises a tool which fixes the sliding plate, a third basic portion which fixes the tool, a second basic portion which bears the third basic portion, a first pressure imposing device which imposes pressure on the workpiece, a driving device which drives the sliding block to slide, a second pressure imposing device exerting certain pressure on the sliding block and an acceleration sensor which is arranged below the workpiece, wherein the tool comprises a base and lifting handles which are arranged at two ends of the base. Due to the lifting handles, the tool can be handily lifted and manual operation is convenient.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a vibration testing machine. Background technique [0002] With the rapid development of China's auto industry, my country's auto parts industry has integrated into the international market, and more and more multinational companies regard China as a world-wide auto parts manufacturing center. However, the technical content and product quality of domestic passenger car seat slide rails vary, which restricts the development of the market to a certain extent. [0003] Slide rails for passenger car seats are one of the main functions of passenger car seats. Due to the rapid development of passenger car seats in recent years, the requirements for functional parts of passenger car seats are also getting higher and higher. How to test the stability of its function is already an imminent problem. [0004] The vibration testing machine tests the stability of the seat slide rail duri...
