Description

Technical Field

[0001] This utility model belongs to the field of machine tool accessories, and relates to a machine tool housing, and particularly to a novel machine tool housing. Background Technology

[0002] CNC machine tools are short for numerical control machine tools. They are automated machine tools equipped with a program control system. CNC machine tools have solved the problems of machining complex, precise, small-batch, and multi-variety parts. They are flexible and high-efficiency automated machine tools, representing the development direction of modern machine tool control technology. They are a typical mechatronics product. The housing of a CNC machine tool can provide a certain degree of protection.

[0003] Currently, some CNC machine tool housings still have some problems during use. For example, the existing CNC machine tool housings are not strong enough and do not have noise reduction and vibration resistance effects, which have a significant impact on the working environment of operators. Under long-term use, CNC machine tool housings may develop cracks and partial bending deformation, posing certain safety hazards. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a novel machine tool housing to solve these problems.

[0005] The purpose of this utility model can be achieved through the following technical solution: a novel machine tool housing, including a machine tool base and multiple protective plates, wherein the multiple protective plates cooperate to form a closed protective cover, characterized in that the protective plate includes a parallel metal inner plate and a metal outer plate, and a plurality of supporting members for enhancing the structural strength of the protective plate are sandwiched between the metal inner plate and the metal outer plate, and the plurality of supporting members are arranged in sequence at intervals and fixedly connected to the metal inner plate and the metal outer plate by integral molding;

[0006] The supporting member is arranged in an X-shaped structure. Sound-absorbing cotton for sound absorption and noise reduction is provided between the supporting member and the inner and outer metal plates. A rubber filler strip with buffering and vibration absorption is filled between two adjacent supporting members.

[0007] The supporting member has a V-shaped branch structure at the intersection of its components. The open ends of the V-shaped branches are welded and fixed to the inner metal plate and the outer metal plate, respectively. The connection between the V-shaped branches and the supporting member forms a triangular cross-section supporting cavity, and the sound-absorbing cotton is located inside the supporting cavity.

[0008] In the aforementioned novel machine tool housing, a rubber gasket is inlaid on the outside of the inner metal plate, the outer metal plate is made of lightweight aluminum alloy sheet, the inner metal plate is made of stainless steel sheet, and the surface of the outer metal plate is coated with an anti-corrosion coating.

[0009] In the aforementioned novel machine tool housing, the sound-absorbing cotton is a multi-layer polyester fiber composite material, the rubber filler strip is made of nitrile rubber, and its surface is provided with a honeycomb-shaped buffer microporous structure.

[0010] Compared with existing technologies, this novel machine tool housing has the following advantages:

[0011] 1. The topology optimization design of the X-shaped support component, combined with the aluminum alloy outer plate, reduces weight while ensuring the rigidity of the protective cover. It is suitable for high-precision machine tools that have the dual requirements of stability and portability. The density gradient design of the sound-absorbing cotton is designed to absorb noise in different frequency bands. The rubber filler strip disperses vibration energy through microporous compression, reducing resonance transmission during machine tool operation.

[0012] 2. The combination of stainless steel inner plate and corrosion-resistant outer plate is suitable for industrial environments such as humid and oily conditions, reducing maintenance costs. The one-piece molding process reduces assembly steps, avoids the structural weaknesses of traditional connection methods, and reduces the risk of failure. Attached Figure Description

Detailed Implementation

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2 , Figure 3As shown, this novel machine tool housing includes a machine tool base and multiple protective plates. The multiple protective plates cooperate to form a closed protective cover. The protective plates include parallel metal inner plates and metal outer plates. Several support members for enhancing the structural strength of the protective plates are sandwiched between the metal inner plates and the metal outer plates. The support members are arranged in sequence at intervals and are fixedly connected to the metal inner plates and metal outer plates by integral molding. The support members are arranged in an X-shaped structure. Sound-absorbing cotton for sound absorption and noise reduction is provided between the support members and the metal inner plates and metal outer plates. Rubber filler strips with buffering and vibration absorption are filled between two adjacent support members. V-shaped branch structures are provided at the intersection nodes of the support members. The open ends of the V-shaped branches are welded and fixed to the metal inner plates and metal outer plates respectively. The connection between the V-shaped branches and the support members forms the support cavity with a triangular cross section. The sound-absorbing cotton is located in the support cavity.

[0019] The topology-optimized design of the X-shaped support component, combined with the aluminum alloy outer plate, reduces weight while ensuring the rigidity of the protective cover. This makes it suitable for high-precision machine tools that require both stability and portability. The density gradient design of the sound-absorbing cotton is specifically designed to absorb noise in different frequency bands, and the rubber filler strips disperse vibration energy through microporous compression, reducing resonance transmission during machine tool operation.

[0020] The inner metal panel is inlaid with rubber gaskets. The outer metal panel is made of lightweight aluminum alloy, while the inner metal panel is made of stainless steel. The outer metal panel is coated with an anti-corrosion coating. The sound-absorbing cotton is a multi-layer polyester fiber composite material, with its density decreasing layer by layer from the inner metal panel to the outer metal panel. The rubber filler strip is made of nitrile rubber, and its surface has a honeycomb-like buffer microporous structure.

[0021] The combination of a stainless steel inner panel and an outer panel with an anti-corrosion coating makes it suitable for industrial environments such as humidity and oil, reducing maintenance costs. The one-piece molding process reduces assembly steps, avoids the structural weaknesses of traditional connection methods, and reduces the risk of failure.

[0022] The X-shaped cross structure evenly distributes the load, significantly improving the compressive and bending resistance of the protective plate. Meanwhile, the V-shaped branches are welded and fixed to the metal plate, forming a triangular cross-section support cavity, further enhancing local rigidity. Multiple layers of polyester fiber sound-absorbing cotton (density decreasing from the inside to the outside) are filled between the X-shaped support components, effectively absorbing high-frequency noise. The honeycomb microporous structure of the nitrile rubber filler strips buffers low-frequency vibrations, achieving multi-frequency noise reduction.

[0023] The outer metal panel is made of lightweight aluminum alloy, reducing the overall weight; the inner metal panel is made of stainless steel, ensuring corrosion resistance and strength, while the anti-corrosion coating on the outer panel surface extends its service life. The supporting components are connected to the inner and outer metal panels through an integral molding process, avoiding stress concentration problems associated with welding or bolted connections and improving the overall structural stability.

[0024] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0025] Although this document uses a lot of technical terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any kind of additional limitation would contradict the spirit of this invention.
