[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0042] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0044] The main solution of the embodiment of the present application is: Figures 2 to 3 As shown, the embodiment of the present application provides a method for processing the closed angle area of ​​a high overhang part:

[0045] Adjust the machining equipment to the origin of the machining coordinate system; wherein the machining equipment includes a five-axis machine tool and a forty-five-degree angle head 200, and the forty-five-degree angle head 200 is installed on the machine tool spindle 100 of the five-axis machine tool; obtain the coordinates of the target machining area in the machining coordinate system; based on the coordinates of the target machining area in the machining coordinate system, obtain the angle between the forty-five-degree angle head and the machine tool spindle corresponding to the coordinate position and the B-axis and C-axis rotation angles of the five-axis machine tool; based on the angle between the forty-five-degree angle head and the machine tool spindle and the B-axis and C-axis rotation angles of the five-axis machine tool, start the five-axis machine tool to complete the machining.

[0046] It can be imagined that a method for processing closed-angle areas of high-overhang parts provided in an embodiment of the present application, after obtaining the coordinates of the target processing area, adjusts the angle between the forty-five-degree angle head and the machine tool spindle and the rotation angles of the B-axis and C-axis of the five-axis machine tool, so that the spindle of the five-axis machine tool avoids the workpiece to be processed, and uses the forty-five-degree angle head itself to rotate around the Z-axis of the machine tool, thereby completing the processing of the closed-angle area.

[0047] In the specific implementation process, it is not difficult to understand that since most parts are mass-produced, in order to effectively improve the processing efficiency, the processing program is usually programmed into the machine tool to achieve uninterrupted batch processing of parts. To this end, in order to achieve the purpose of automated production, this application establishes a relevant database in the workpiece production process, so that the corresponding data can be retrieved for production and manufacturing.

[0048] Specifically:

[0049] In this embodiment, obtaining the coordinates of the target processing area in the processing coordinate system includes the following steps:

[0050] S1: Establish the three-dimensional modulus of the target workpiece;

[0051] S2: based on the three-dimensional digital model of the target workpiece, obtaining the workpiece coordinates of the target workpiece;

[0052] S3: The workpiece coordinates of the target workpiece are converted into the coordinates of the target workpiece in the machining coordinate system through software;

[0053] S4: Based on the coordinates of the target workpiece in the processing coordinate system, a coordinate database of each target processing area in the processing coordinate system is established.

[0054] It can be understood that after the coordinates of each target processing area in the processing coordinate system form a database, the relevant information is entered into the processing program. When the machining equipment processes different target areas, the five-axis machine tool will automatically retrieve the coordinate information of the corresponding target processing area, thereby moving the spindle to the corresponding target area.

[0055] In the above, the three-dimensional modeling of the target workpiece and the conversion of the workpiece coordinates into the processing coordinates can be completed by UG, CAXA and other related three-dimensional software.

[0056] Alternatively, based on the coordinates of the target processing area in the processing coordinate system, obtaining the angle between the 45-degree angle head and the machine tool spindle corresponding to the coordinate position includes:

[0057] Move the machining equipment to different target machining areas through simulation software;

[0058] The angle between the 45-degree angle head and the machine tool spindle is adjusted by simulation software, the angle between the 45-degree angle head and the machine tool spindle when the target processing area is not affected is recorded, and a database of the angle between the 45-degree angle head and the machine tool spindle when the target processing area is not affected is established;

[0059] Based on the database of the angle between the forty-five-degree angle head and the machine tool spindle, the angle between the forty-five-degree angle head and the machine tool spindle corresponding to the target processing area is retrieved.

[0060] In this process, if Figure 4 As shown, in the initial state, the machining equipment is at the initial position, and the rotation angles of the machine tool Z axis, B axis, and C axis are all zero degrees, as shown in Figure 5 and Figure 6 As shown, the machine tool spindle is moved to the target area, and then the angle between the 45-degree angle head and the machine tool spindle is manually adjusted. When the 45-degree angle head does not interfere with the workpiece, the corresponding angle is recorded, and the corresponding angle between the 45-degree angle head and the machine tool spindle when the 45-degree angle head does not interfere with the workpiece when processing different target processing areas is obtained in turn, thereby establishing a database. After the database is established, the corresponding data is entered into the processing program. Each time the program is called in the future, the angle between the 45-degree angle head and the spindle in the target processing area can be directly obtained, thereby avoiding interference with non-target processing areas during processing.

[0061] At the same time, based on the coordinates of the target processing area in the processing coordinate system, the B-axis and C-axis rotation angles of the five-axis machine tool corresponding to the coordinate position are obtained, including:

[0062] Move the machining equipment to different target machining areas through simulation software;

[0063] The simulation software is used to adjust the rotation angles of the B-axis and C-axis of the machine tool when they do not interfere with the target workpiece in each target processing area, and the data is recorded to establish a database of the B-axis and C-axis rotation angles of the five-axis machine tool that do not affect the processing in different target processing areas.

[0064] Based on the B-axis and C-axis rotation angle database of the five-axis machine tool, the B-axis and C-axis rotation angles of the five-axis machine tool corresponding to the target processing area are retrieved.

[0065] When implementing it, Figure 4 As shown, in the initial state, the machining equipment is at the initial position, and the rotation angles of the machine tool Z axis, B axis, and C axis are all zero degrees, as shown in Figure 5 and Figure 6As shown, move the machine tool spindle to the target area, and after manually adjusting the 45-degree angle head so that there is no interference with the workpiece, rotate the B-axis and the C-axis so that there is no interference with the workpiece, record the data and form a database, and after the database is established, enter the corresponding data into the processing program. Each time the program is called thereafter, the angle between the 45-degree angle head and the spindle in the target processing area can be directly obtained, thereby avoiding interference with non-target processing areas during processing.

[0066] In summary, the method of processing the closed-angle area of ​​high overhang parts in the present application, after obtaining the coordinates of the target processing area, adjusts the angle between the forty-five degree angle head and the machine tool spindle and the rotation angles of the B-axis and C-axis of the five-axis machine tool, so that the spindle of the five-axis machine tool avoids the workpiece to be processed, and uses the forty-five degree angle head itself to rotate around the Z-axis of the machine tool, so that the closed-angle area of ​​the high overhang part can be processed.

[0067] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
