Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laser cutting machine guide rails, in particular to a high-precision and low-cost guide rail structure. Background Art
[0002] Existing laser cutting machines require increasingly higher precision rails. Extruded aluminum profiles are unstable, and the required rail precision for laser cutting machines cannot be achieved directly on the profile. Extruded profiles exhibit torsion, and the flatness fails to meet the required rail precision for laser cutting machines (extruded profiles can only meet the national standard for standard extrusions, which is significantly different from customer requirements). This increases our scrap rate and costs. (Because all precision requirements are relative to two semicircular slots at the top for mounting the optical axis, if the profile has a large hollow space in the middle, it is impossible to achieve the required rail precision using low-cost machining methods.)
[0003] As shown in the following drawings, the profiles of these guide rails are generally shaped like Figure 1 (profile for mounting the optical axis) and Figure 2 (Profile and base square for installing the optical axis):
[0004] There are two semicircular grooves on the top for installing the optical axis. The shape is generally square or rectangular, with an empty space in the middle as shown in the figure. Although these guide rails look relatively square in overall appearance, because the shapes and sizes of the four sides are different and there is a large empty space in the middle, it is generally difficult for aluminum factories to ensure the flatness of the bottom when the aluminum profile is extruded. The profile is prone to the following Figure 3 The bottom surface in the X direction (long side) is uneven in the middle, and Figure 4 The Y direction (narrow side) is shown to be distorted.
[0005] Therefore, the accuracy of the existing laser cutting machine guide rails needs to be improved, and the cost needs to be reduced. Therefore, the present invention proposes a high-precision and low-cost guide rail structure. Utility Model Content
[0006] Technical problems solved
[0007] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a high-precision and low-cost guide rail structure.
[0008] Technical Solution
[0009] To achieve the above objectives, the present invention provides the following technical solutions: a high-precision, low-cost guide rail structure, comprising a guide rail profile laser cutting machine guide rail with no empty space in the middle, a semicircular groove laser cutting machine guide rail for mounting an optical axis provided at both ends of the guide rail profile laser cutting machine guide rail, and a square laser cutting machine guide rail installed at the bottom of the guide rail profile laser cutting machine guide rail. By providing a guide rail profile laser cutting machine guide rail with no empty space in the middle, the improved aluminum profile has no empty space in the middle, so when the aluminum profile is extruded, the aluminum factory can more easily ensure the flatness of the bottom surface, effectively reducing the scrap rate of the aluminum profile and improving the overall horizontal accuracy. (If the extruded profile has an uneven bottom or is distorted and does not meet the customer's requirements, it can be machined to meet the customer's accuracy requirements without scrapping the profile).
[0010] Preferably, there are two semicircular groove laser cutting machine guide rails on each guide rail profile laser cutting machine guide rail, and the two semicircular groove laser cutting machine guide rails are symmetrically arranged on both sides of the guide rail profile laser cutting machine guide rail.
[0011] Preferably, the semicircular groove laser cutting machine guide rails are arranged on both sides of the outside of the guide rail profile laser cutting machine guide rails.
[0012] Preferably, the semicircular groove laser cutting machine guide rails are arranged on both sides of the interior of the guide rail profile laser cutting machine guide rails.
[0013] Beneficial effects:
[0014] Compared with the existing technology, this high-precision and low-cost guide rail structure has the following beneficial effects:
[0015] This utility model provides a guide rail profile with no empty space in the middle. The improved aluminum profile has no empty space in the middle. Therefore, when the aluminum profile is extruded, the aluminum factory can more easily ensure the flatness of the bottom surface, effectively reducing the scrap rate of the aluminum profile and improving the overall horizontal accuracy. If the extruded profile has an uneven bottom or distortion and does not meet the customer's requirements, we can use machining to achieve the required accuracy. The square tube itself can also be machined to achieve higher accuracy. The overall combination with the square tube can be installed to meet the increasingly high mechanical accuracy requirements of the laser cutting machine and reduce the scrap cost of the aluminum profile.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] For example 1, please refer to Figure 5-Figure 7 , it is shown that the utility model provides a technical solution: a high-precision and low-cost guide rail structure, wherein semicircular grooves 2 are arranged on both sides of the outside of the guide rail profile 1, including a guide rail profile 1 with no empty space in the middle, and semicircular grooves 2 for installing the optical axis are provided at both ends of the guide rail profile 1, and a square passage 3 is installed at the bottom of the guide rail profile 1, and there are two semicircular grooves 2 on each of the guide rail profiles 1, and the two semicircular grooves 2 are symmetrically arranged on both sides of the guide rail profile 1.
[0029] For example 2, please refer to Figure 8, it is shown that the utility model provides a technical solution: a high-precision and low-cost guide rail structure, wherein semicircular grooves 2 are arranged on both sides of the inside of the guide rail profile 1, including a guide rail profile 1 with no empty space in the middle, and semicircular grooves 2 for installing the optical axis are provided at both ends of the guide rail profile 1, and a square passage 3 is installed at the bottom of the guide rail profile 1, and there are two semicircular grooves 2 on each of the guide rail profiles 1, and the two semicircular grooves 2 are symmetrically arranged on both sides of the guide rail profile 1.
[0030] Working principle: By setting the guide rail profile 1 with no empty space in the middle, the improved aluminum profile has no empty space in the middle, so when the aluminum profile is extruded, the aluminum factory can more easily ensure the flatness of the bottom surface. Even if there are some unevenness and distortion after the aluminum profile is extruded, it can be fixed on a plane with a flatness standard to flatten the entire profile during use. If the aluminum profile is relatively uneven and distorted after extrusion, we can also use machining methods to keep the optical axis at both ends balanced and the use height consistent, thereby reducing the scrap rate of the aluminum profile and improving the overall horizontal accuracy.
