Description

Technical Field

[0002] Also known as a machine tool or working machine, it is usually referred to as a machine tool. It is generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. Parts with high precision requirements and fine surface roughness requirements generally need to be finally processed on machine tools by cutting methods. Machine tools play a major role in the construction of national economic modernization. With the rapid development of science and technology, CNC machine tools are widely used in mechanical processing due to their high work efficiency and good product quality. The bases of CNC machine tools on the market are mostly made of one-piece castings. They are formed by integral casting. When making them, the molten metal liquid is poured into a pre-made mold. The castings in the machine tool industry are mostly sand castings, about 70% of which are sand castings. It is produced with clay, and the castings produced by sand casting are often poor in terms of accuracy, surface finish, material density and metallographic structure, mechanical properties, shock absorption performance, etc., and the fixed installation of mechanical machine tools is often a problem that people are more concerned about, because machine tools often generate vibrations when working, and the general installation of CNC machine tools is to install the CNC machine tools directly on the surface poured with concrete.

[0034] The working principle of the present invention is as follows: the machine tool is mounted on the mounting platform 1. Due to the different weight distribution of machine tools of different models, the gas inside the air spring device 5 is squeezed and the gas is squeezed to the balance detector 507. The pointer 5071 swings left and right. In order to make the force uniform, the dual-axis motor 704 is controlled to rotate forward and reverse, which can drive the lateral movement block 701 to move horizontally. When the pointer 5071 is balanced, the telescopic structure 7032 is controlled to extend to position it to the positioning hole opened on the mounting platform 1, so that the lateral movement block 701 is fixed, so that the machine tool is uniformly stressed, which helps to improve the stability of the machine tool. The second compression spring 302 is used to reduce the vibration of the machine tool during operation, and the damping device 303 is used to reduce the vibration of the machine tool during operation. Device 4 can reduce the vibration of the machine tool laterally during operation. The shock-absorbing cotton 301 can be used to further reduce the collision with the ground, thereby reducing the noise. Due to excessive use of the machine tool, the life of the second compression spring 302 is gradually reduced, and the shock-absorbing effect is getting smaller and smaller. At this time, the wheel 407 at the bottom of the damping device 4 will slide to the left and right. When the wheel 407 contacts the hydraulic top switch 405, the hydraulic device 6 is started, so that the lifting structure 607 lifts the mounting table 1 upward. The noise collection device 605 on one side of the hydraulic device 6 can convert the noise generated during the operation of the machine tool into electrical energy, and store the electrical energy in the battery 604 to ensure that the hydraulic device 6 has electricity supply when it needs to work.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
