[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

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 second pressure imposing device comprises two pressure imposing pieces, an installation portion which fixes the pressure imposing pieces and a driving lever, wherein each pressure imposing piece comprises a pressuring imposing arm, a pressure imposing rod and a connecting rod which is connected with the pressure imposing arm and the pressure imposing rod, and the pressure imposing rod is provided with a contact portion which contacts with the workpiece in an abutting mode. Through the effect of the contact portion, collision damage to the pressure imposing rod and the workpiece is avoided and work efficiency 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 global auto parts manufacturing center. The technical content and product quality of domestic passenger car seat slides are uneven, which restricts the development of the market to a certain extent. [0003] The slide rail for passenger car seats is one of the main functions of passenger car seats. Due to the rapid development of passenger car seats in recent years, the requirements for passenger car seat functional parts are getting higher and higher. How to test the stability of its function is already an urgent problem. [0004] The vibration testing machine tests the stability of the seat slide rail during the sliding proces...
