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

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. But these embodiments do not limit the specific embodiments of the present invention

[0031] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0032] Such as Figure 1-Figure 20 As shown, a vibration testing machine 100 is used to test the vibration of the workpiece 2. The vibration testing machine 100 includes a tooling 3 for supporting the workpiece 2, a base 4 connected to the tooling 3, and a support for the workpiece 2. 2 The first pressure applying device 5 and the second pressure applying device 6 that play a pressing role, the accelerati...

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 which imposes certain force on the sliding block and an acceleration sensor which is arranged below the workpiece. The first pressure imposing device comprises a first cylinder which controls vertical motion, a second cylinder which controls horizontal motion, a first working platform which is connected with the first cylinder and a second working platform which is connected with the second cylinder, wherein a plurality of limiting rods are arranged at the lower portion of the second working platform. Due to the limiting rods arranged at the lower portion of the second working platform, horizontal sliding of the second working platform in the vertically moving process is prevented, the influence on a test result is reduced and test accuracy is improved.

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...
