Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbing structures, in particular to a shock absorbing structure for a machine tool. Background Art

[0002] Machine tools refer to machines used to manufacture machines, also known as machine tools or machine tools, and are usually referred to as machine tools. They are generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. There are many methods for processing mechanical parts in modern machinery manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. However, all 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.

[0003] At present, in the prior art, when a machine tool cuts metal materials, the tool and the surface of the metal material squeeze each other, causing the machine tool body to vibrate irregularly. This vibration will cause the tool to vibrate during the processing, resulting in irregular vibration marks on the surface of the workpiece during the cutting process, resulting in a decrease in the smoothness of the workpiece surface. In view of this, we propose a shock-absorbing structure for machine tools. Summary of the invention

[0011] Preferably, a control computer is fixedly connected to the surface of the housing. Beneficial Effects

[0012] The utility model provides a shock absorbing structure for a machine tool, which has the following beneficial effects:

[0013] (1) The shock-absorbing structure for a machine tool generates vibrations when the device body starts to work through the provided linkage rod, so that the outer shell begins to shake irregularly in the plane, and the device body transmits the vibration force to the inside of the shock-absorbing base through the connector, so that the rotating rod rotates irregularly, and the rotating rod drives the flower-shaped turntable to rotate, so that the flower-shaped turntable moves by pulling the damping slider through the linkage rod, thereby greatly reducing the vibration of the device body, and through the provided friction layer, the surface of the friction layer and the surface of the rotating rod rub against each other, thereby further weakening the vibration of the device body.

[0014] (2) The shock-absorbing structure for a machine tool has a damper arranged therein. When the device body starts to work, the device body generates vibrations, causing the outer shell to start to twitch up and down. The vibration of the outer shell is transmitted to the inside of the shock-absorbing base through the connector. The combination of the damper and the spring can further weaken the up and down twitching of the device body. BRIEF DESCRIPTION OF THE DRAWINGS
