[0032] see figure 1 and figure 2 , the main beam 1 is made of carbon fiber cloth by hot pressing process. In a specific example, T300 carbon fiber cloth hot pressing process is used to prepare.

[0033] The guide rail base 2 is formed by splicing a plurality of independent guide rail base sections 21 / 22 end to end, and two guide rail mounting holes are provided on each guide rail base section (21 / 22).

[0034] Wherein, the guide rail base section 21 with an "L"-shaped cross-section is arranged in the guide rail base installation groove 11 on the top surface, and the guide rail installation surface includes a top straight surface 212 and a top flat surface 211 . A guide rail base segment 22 with a "-"-shaped cross-section is arranged in the guide rail base installation groove 11 on the side surface, and the guide rail installation surface only includes a top plane 221 . The cross-beam of the rectangular cross-section of this scheme is a rectangle, the side length of the cro...

[0048] see image 3 and Figure 4 , Composite beam, the main beam 1 is prepared by T700 carbon fiber pultrusion process. The guide rail base 2 is made of marble or mineral casting, and the mineral casting mixture includes quartz sand, cobblestone, natural marble powder, and epoxy resin.

[0049] The guide rail base 2 of this solution is directly cast on the main beam 1, so it is an integral structure, and the cross section is "-" shape, and only the top plane 201 is the installation surface. This solution does not require the additional application of adhesive 3 .

[0050] In this solution, the rectangular section of the main beam 1 is a rectangle, and the top surface corresponds to the long side of the section. In one example, two guide rail base mounting slots 11 are provided in parallel on the top surface for installing two guide rail bases 2 .

[0051]The size of the composite beam is 1800mm in length and 120X120mm in section.

[0063] Different from the first two embodiments, the composite beam is not provided with the guide rail base 2, and the installation surface of the entire main beam 1 can have installation grooves or not, that is, a smooth surface (not shown in the figure). The smooth surface or the installation groove is used as the air floating surface, and the air floating pad is installed on this surface to realize the installation of the air floating guide rail. The air-floating guide of this scheme has high precision. Air-floating guide rail assemblies (not shown) can be arranged around the composite beam.

Abstract

The invention provides a composite crossbeam and a manufacturing method thereof, which belong to the field of bench-type instrument beam manufacturing. The composite crossbeam includes a main beam made of carbon fiber and a guide rail base made of pure marble or mixed materials. The guide rail base is composed of multiple Two independent guide rail base sections are spliced ​​end to end; the material of the guide rail base is made of marble or mineral pouring, and the mixture of mineral pouring includes quartz sand, pebbles, natural marble powder, and epoxy resin. The manufacturing method of the crossbeam includes preparing a carbon fiber main beam, preparing and installing a guide rail base, opening holes in the base and finishing the installation surface of the guide rail. Due to the use of composite material beams, the scheme has the characteristics of light weight, good rigidity and toughness, high stability, good processability and low cost.

Description

technical field [0001] The invention belongs to the field of beam manufacturing of bench-type instruments, in particular to a composite beam and a manufacturing method thereof. Background technique [0002] Mobile bridge type (or moving beam type) gantry structure is a common mechanical structure, which is widely used in manufacturing or testing equipment such as imagers, coordinate measuring machines, laser cutting machines, gantry milling machines, and glue dispensing machines. The beam in the gantry structure is an important part of this type of equipment. [0003] Usually the beam is required to have high rigidity, high precision and high stability to ensure the overall accuracy and performance of the equipment. Therefore, the beams of high-precision equipment are mostly made of natural marble or aluminum alloy. However, the beams of the above-mentioned materials have their own advantages and disadvantages. Among them, the beams made of natural marble generally have th...
