Description

Technical Field

[0001] This utility model relates to the field of CNC woodworking machinery technology, specifically to a wood carving and milling machine with a self-calibrating reference. Background Technology

[0002] Wood carving and milling machines are precision machining equipment controlled by a computer. Their machining accuracy largely depends on the perpendicularity and parallelism accuracy between the X, Y, and Z linear motion axes. Traditional high-precision carving and milling machines typically use a separately manufactured marble platform or ruler as a reference to calibrate each axis. The advantage of this method is that the reference itself has high accuracy and good stability.

[0003] However, this method has significant drawbacks: First, high-precision marble reference pieces are expensive, costly to procure, and brittle, heavy, and inconvenient to transport and carry. Second, for equipment that needs to be assembled at the customer's site or readjusted after major repairs, such high-precision reference tools are often unavailable on-site, making the readjustment impossible or preventing the accuracy from being restored to factory settings. Finally, even with marble references, the calibration process is cumbersome, requiring repeated handling and repositioning, resulting in low efficiency. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to provide a wood carving and milling machine with a self-calibrating reference.

[0005] To achieve this technical objective, the present invention provides a wood carving and milling machine with a self-calibrating reference, comprising a base and a frame. The frame consists of a column and a crossbeam mounted on the upper part of the column. A slide block movable along the X-axis is mounted on the crossbeam, and a carving and milling assembly movable along the Z-axis is mounted on the slide block. A worktable for carrying the workpiece and moving it along the Y-axis is mounted on the base. The column has an L-shaped structure with mutually perpendicular vertical and horizontal wing plates. A first reference portion in the same direction as the Z-axis is provided on the vertical wing plate for Z-axis calibration, and a second reference portion in the same direction as the Y-axis is provided on the horizontal wing plate for Y-axis calibration. The first and second reference portions are perpendicular to each other.

[0006] Preferably, the first reference part is a rectangular strip structure with a rectangular cross-section, which is fixed or integrally formed on the vertical wing plate. The first reference part has two reference planes for calibration, namely the end face with the largest area and the side face with the largest area of ​​the rectangular strip structure.

[0007] Preferably, the second reference part is a rectangular strip structure with a rectangular cross-section, which is fixed or integrally formed on the transverse wing plate. The second reference part has two reference planes for calibration, namely the end face with the largest area and the side face with the largest area of ​​the rectangular strip structure.

[0008] Preferably, the frame includes two uprights, located on both sides of the crossbeam.

[0009] Preferably, both columns are provided with the first reference part and the second reference part.

[0010] The beneficial effects of this utility model are as follows: By directly machining mutually perpendicular first and second reference parts on the L-shaped column of the frame, the problem of inconvenient transportation and carrying of reference tools is completely solved. Furthermore, since the reference surface is located on the main structure of the equipment, calibration personnel do not need to move marble; they can directly fix measuring instruments (such as dial indicators) to the milling assembly or worktable and have their probes contact the corresponding reference surfaces for measurement, greatly simplifying the process and improving calibration efficiency. Because the first and second reference parts are machined from the same L-shaped column, their inherent perpendicularity accuracy is high, resulting in more precise measurement data. This ingenious structural design achieves a perfect unity of function and structure, improving product performance without significantly increasing manufacturing costs. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. To provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; these embodiments are only some embodiments of the present invention; other embodiments obtained based on this application without creative effort are all within the scope of protection of the present invention.

[0018] In the following embodiments, it should be noted that the terms "upper," "lower," "left," "right," "inner," "outer," "top / bottom," etc., are all based on the orientation or positional relationship shown in the accompanying drawings and are only for the purpose of clearly describing this embodiment. They do not indicate or imply that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application. At the same time, the terms "first" and "second" in the embodiments are only used for descriptive purposes and do not represent an indication or implication of relative importance.

[0019] like Figure 1-5 As shown, a specific embodiment of this utility model is a wood carving and milling machine with a self-calibrating reference. Its main structure includes a stable base 1. A frame 2 is fixedly installed on the base 1. The frame 2 consists of two columns 21 and a crossbeam 22 supported on the columns, forming a stable frame structure.

[0020] A device that can be mounted on the crossbeam 22 along the X-axis direction ( Figure 1 The slide 3 moves precisely in the forward and backward direction (as shown). The milling assembly 4 (typically including an electric spindle and tool clamping mechanism) is mounted on the slide 3 to perform the milling operation. The milling assembly 4 can move along the Z-axis direction (as shown). Figure 1 The machine base 1 is equipped with a mechanism that can move along the Y-axis (vertical direction as shown). Figure 1 The worktable 5 (which moves in the left and right directions as shown) is used to carry and transport the wooden workpieces to be processed.

[0021] The core improvement of this utility model lies in the structural design of the column 21. The column 21 has an L-shaped structure, consisting of a vertical wing plate 211 and a horizontal wing plate 212 perpendicular to it. On the outer surface of the vertical wing plate 211, a rectangular strip structure with a rectangular cross-section is fixed or integrally formed. The end face and the side face with the largest area of ​​this strip constitute the first reference part 6, which consists of two high-precision vertical planes. Correspondingly, on the outer surface of the horizontal wing plate 212, a rectangular strip structure with a rectangular cross-section is also fixed or integrally formed. The end face and the side face with the largest area of ​​this strip constitute the second reference part 7, which consists of two high-precision horizontal planes. The two rectangular strip structures are perpendicular to each other.

[0022] For ease of calibration, it is best to machine the same first reference part 6 and second reference part 7 on both columns 21. Of course, it is also possible to machine them on only one column 21.

[0023] The calibration operation of this application is as follows: X-axis and Y-axis perpendicularity calibration: First, fix dial indicator 8 on the worktable 5, with its probe perpendicularly abutting the end face of the largest area of ​​the second reference part 7. Drive the worktable to move along the Y-axis direction. By observing the change in the reading of dial indicator 8, the perpendicularity error of the Y-axis direction in the horizontal plane relative to the X-axis movement can be determined. Second, place the probe of dial indicator 8 perpendicularly abutting the side face of the largest area of ​​the second reference part 7. Drive the worktable to move along the Y-axis again. By observing the change in the reading of dial indicator 8, the parallelism error of the Y-axis direction in the vertical plane relative to the X-axis movement can be determined.

[0024] X-axis and Z-axis perpendicularity calibration: Step 1: Fix dial indicator 82 to the milling assembly 4, ensuring its probe is perpendicularly against the end face (upper surface) of the largest area of ​​the first reference part. Drive the milling assembly along the Z-axis direction. By observing the change in the dial indicator 8 reading, the perpendicularity error between the Z-axis and the X-axis movement in the vertical plane can be determined. Step 2: Horizontally contact the probe of dial indicator 8 against the side face (right surface) of the largest area of ​​the first reference part. Drive the milling assembly along the Z-axis again. By observing the change in the dial indicator 8 reading, the parallelism error between the Z-axis and the X-axis movement in the horizontal plane can be determined.

[0025] By adjusting in the above two steps, the X-axis and Z-axis can be ensured to achieve an ideal perpendicular relationship in three-dimensional space. The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Any minor modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of this utility model should be included within the protection scope of this utility model's technical solution.
