Description

Technical Field

[0001] The utility model relates to the technical field of precision measuring equipment, in particular to an anti-torsion low-mass crossbeam for a coordinate measuring machine. Background Technique

[0002] With the rapid development of modern manufacturing industry, as an important equipment in the field of precision measurement, the accuracy, stability and durability of a coordinate measuring machine have become important indicators to measure its performance. However, in actual applications, the crossbeam of a coordinate measuring machine, as a supporting and moving component, often needs to bear forces and torques from different directions. Especially when measuring complex workpieces, the anti-torsion ability and stability of the crossbeam are particularly important.

[0003] Traditional crossbeam designs often focus on improving structural strength and use thick and heavy materials to resist external loads. However, this design often leads to an overly heavy crossbeam, which not only increases the overall energy consumption of the measuring machine but also limits its flexibility and mobility. At the same time, when the thick and heavy crossbeam bears complex torsional forces, local stress concentration is likely to occur, resulting in structural fatigue and damage, shortening the service life. Therefore, an anti-torsion low-mass crossbeam for a coordinate measuring machine is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and an anti-torsion low-mass crossbeam for a coordinate measuring machine is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an anti-torsion low-mass crossbeam for a coordinate measuring machine, including a crossbeam body, wherein reinforcing ribs are arranged inside the crossbeam body. There are multiple groups of the reinforcing ribs, and the multiple groups of reinforcing ribs are arranged in a staggered manner and form a honeycomb structure. A lightweight material layer is arranged on the crossbeam body.

[0006] As a further description of the above technical scheme:

[0007] A wear-resistant coating, an anti-corrosion coating and an anti-slip coating are sequentially arranged on the surface of the lightweight material layer. The anti-corrosion coating is located above the wear-resistant coating, and the anti-slip coating is located above the anti-corrosion coating.

[0008] As a further description of the above technical scheme:

[0009] The reinforcing rib structure is made of a high-strength metal material, and the reinforcing ribs are fixed inside the crossbeam body by welding.

[0010] As a further description of the above technical scheme:

[0011] The crossbeam body uses a lightweight and high-strength alloy material as the matrix.

[0012] As a further description of the above technical solution:

[0013] The lightweight material layer is made of a lightweight metal thin plate, and the lightweight material layer is tightly combined with the crossbeam body through bonding.

[0014] As a further description of the above technical solution:

[0015] The wear-resistant coating is made of a ceramic material, and the wear-resistant coating is evenly covered on the lightweight material layer by spraying.

[0016] As a further description of the above technical solution:

[0017] The anti-corrosion coating is made of fluorocarbon paint, and the anti-slip coating is a polymer paint.

[0018] The utility model has the following beneficial effects:

[0019] 1. In the utility model, multiple groups of high-strength metal material reinforcing ribs carefully arranged inside the crossbeam are firmly fixed through a welding process and are staggered to form a honeycomb-like structure. This design significantly improves the torsional stiffness of the crossbeam. During the measurement process, even in the face of various complex torsional forces, the crossbeam can maintain a stable posture, effectively resist deformation. At the same time, the honeycomb-like structure optimizes the stress distribution, avoids local stress concentration, thereby extending the service life of the crossbeam and improving the stability and durability of the overall structure.

[0020] 2. In the utility model, the crossbeam body uses a lightweight and high-strength alloy material as the matrix. This material significantly reduces the weight of the crossbeam while ensuring sufficient strength. In addition, by adding a lightweight metal thin plate as the lightweight material layer and using an advanced bonding technology to tightly combine it with the crossbeam body, the lightweight design is further realized. This design not only reduces energy consumption but also improves the flexibility and mobility of the measuring machine, making the measurement process more convenient and efficient. At the same time, the lightweight design does not sacrifice the performance of the crossbeam, but instead ensures the overall high strength and high stability through a reasonable structural design.

[0021] 3. In the utility model, in order to cope with the complex and changeable working environment, multiple protective coatings are provided on the surface of the crossbeam. The wear-resistant coating is made of a ceramic material and has excellent wear resistance. The anti-corrosion coating is made of fluorocarbon paint and has excellent corrosion resistance, ensuring that the crossbeam can still maintain a good working state in a harsh environment. The outermost anti-slip coating is made of a polymer paint and has good anti-slip performance, ensuring that the surface of the crossbeam is not easy to slide even under wet or greasy working conditions, enhancing the environmental adaptability of the crossbeam and extending its service life.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: an anti-torsion and low-mass crossbeam for a coordinate measuring machine, including a crossbeam body 1, with reinforcing ribs 2 arranged inside the crossbeam body 1. There are multiple groups of reinforcing ribs 2, and the multiple groups of reinforcing ribs 2 are arranged in a staggered manner and form a honeycomb structure. A lightweight material layer 3 is provided on the crossbeam body 1. Multiple groups of high-strength metal material reinforcing ribs 2 carefully arranged inside the crossbeam are firmly fixed by welding technology and arranged in a staggered manner to form a structure similar to a honeycomb. This design significantly improves the anti-torsion stiffness of the crossbeam. During the measurement process, even in the face of various complex torsional forces, the crossbeam can maintain a stable posture, effectively resist deformation. At the same time, the honeycomb structure optimizes the stress distribution, avoids local stress concentration, thereby extending the service life of the crossbeam and improving the stability and durability of the overall structure.

[0029] A wear-resistant coating 4, an anti-corrosion coating 5, and an anti-slip coating 6 are sequentially arranged on the surface of the lightweight material layer 3. The anti-corrosion coating 5 is located above the wear-resistant coating 4, and the anti-slip coating 6 is located above the anti-corrosion coating 5. The reinforcing rib 2 structure is made of high-strength metal material. The reinforcing rib 2 is fixed inside the crossbeam body 1 by welding. The crossbeam body 1 uses a lightweight and high-strength alloy material as the base. The lightweight material layer 3 is made of lightweight metal sheets. The lightweight material layer 3 is tightly bonded to the crossbeam body 1 by adhesion. The wear-resistant coating 4 is made of ceramic material. The wear-resistant coating 4 is evenly covered on the lightweight material layer 3 by spraying. The anti-corrosion coating 5 is made of fluorocarbon paint, and the anti-slip coating 6 is a polymer paint. The crossbeam body 1 uses a lightweight and high-strength alloy material as the base. This material greatly reduces the weight of the crossbeam while ensuring sufficient strength. In addition, by adding lightweight metal sheets as the lightweight material layer 3 and using advanced adhesion technology to tightly bond with the crossbeam body 1, lightweight design is further realized. This design not only reduces energy consumption but also improves the flexibility and mobility of the measuring machine, making the measurement process more convenient and efficient. At the same time, the lightweight design does not sacrifice the performance of the crossbeam. Instead, through reasonable structural design, the overall high strength and high stability are ensured.

[0030] Working principle: In the anti-torsion low-mass crossbeam for a coordinate measuring machine, the core of the crossbeam body 1 lies in multiple groups of stiffeners 2 carefully arranged inside it. These stiffeners 2 are made of high-strength metal materials to ensure sufficient structural strength. Through the welding process, the stiffeners 2 are firmly fixed inside the crossbeam body 1 and are arranged in a staggered pattern to form a honeycomb-like structure. This unique design not only greatly improves the anti-torsion stiffness of the crossbeam, enabling it to resist various torsional forces during the measurement process, but also optimizes the stress distribution. When the crossbeam bears an external load, the honeycomb-like structure can effectively disperse the stress and avoid local stress concentration, thereby extending the service life of the crossbeam, improving the stability and durability of the overall structure. To achieve the goal of lightweight, the crossbeam body 1 uses a lightweight and high-strength alloy material as the matrix. This material not only ensures sufficient strength but also greatly reduces the weight of the crossbeam, improving the flexibility and mobility of the measuring machine. To further reduce the weight, a lightweight metal thin plate is additionally provided outside the crossbeam body 1 as a lightweight material layer 3. This layer is tightly bonded to the crossbeam body 1 through an advanced bonding technology to form a lightweight and robust overall structure. This lightweight design not only reduces energy consumption but also improves the overall performance of the measuring machine. To cope with the complex and changeable working environment, multiple protective coatings are provided on the crossbeam surface. First is the wear-resistant coating 4, which is made of ceramic materials and evenly covers the lightweight material layer 3 through a spraying process. The ceramic materials, with their excellent wear-resistant performance, effectively resist the friction and wear that may occur during the measurement process and protect the integrity of the crossbeam surface. Immediately following is the anti-corrosion coating 5, which is made of fluorocarbon paint and has excellent corrosion resistance. The fluorocarbon paint can resist the erosion of chemical substances such as acids, alkalis, and salts, protecting the crossbeam from damage in a harsh environment. The outermost layer is the anti-slip coating 6, which is made of polymer paint. This coating has good anti-slip performance and can ensure that the crossbeam surface is not easy to slide even under wet or greasy working conditions, improving the safety and stability of operation.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
