Description

Technical Field

[0001] The invention relates to the field of part information marking, and in particular to a method for automatic marking of a slider. Background Art

[0002] After completing the mold design, engineers need to pass the processing information of key parts to the processing personnel, so they need to convert the parts into 2D drawings. The drawings must reflect the relevant size information and processing information of the parts, so designers are required to issue drawings of the parts after the design is completed. Designers need to use different views and mark detailed size and position information in the drawings to provide to the processing personnel. However, the slider has more part size information, and designers need to spend a lot of time on projection and marking, which will result in too many repetitive operations. The marking process is cumbersome and inefficient. Summary of the invention

[0003] The main purpose of the present invention is to identify the processing features on the slider according to the information required for processing and mark them, so as to improve the work efficiency of the designer.

[0004] To this end, the present invention provides a method for automatic marking of a slider, and the technical solution adopted is:

[0005] A method for automatically marking a slider, the method comprising:

[0006] Collect the slider surface and determine the slider reference;

[0007] Obtain the slider plane information according to the slider reference and identify the side of the slider hanging platform;

[0008] According to the identified side of the slider hanging platform, identify the slider hanging platform surface and mark it;

[0009] Confirm the inclined guide post hole according to the slider reference and mark it;

[0010] The threaded holes and the grooves where the threaded holes are located are identified based on the collected surfaces of the slider and marked.

[0011] According to the above scheme, the slider reference is determined as follows:

[0012] Collect the slider surface types of plane and cylindrical surface, take the complete cylindrical surface, and determine whether the cylindrical surface is a through hole. If it is a through hole, the cylindrical surface is identified as a cylindrical through hole surface;

[0013] The direction perpendicular to the plane direction and the direction of the cylindrical through hole surface is taken as the X provisional direction of the slider reference, and the Y provisional direction and Z provisional direction of the slider reference are obtained by the right-hand screw rule;

[0014] From the X-direction and Y-direction, the direction with the smaller angle with the cylinder tilt direction is selected as the X-direction of the slider reference, and the plane direction that is symmetrical and perpendicular to the X-direction is found to obtain the Y-direction of the slider reference. The Z-direction is confirmed as the Z-direction.

[0015] According to the above scheme, whether the cylindrical surface is a through hole is determined specifically by the ray method.

[0016] According to the above scheme, the side of the slider hanging platform is specifically identified as follows:

[0017] Get the plane and plane information of the slider, determine the plane parallel to the Y direction, take the projection distance from the point on the plane to the highest point of the slider in the Y direction, if a plane has a minimum projection distance and the minimum value is greater than 0, then this plane is confirmed as the side of the slider hanging platform.

[0018] According to the above scheme, the plane parallel to the Y direction is determined by multiplying the plane direction by the Y direction of the slider reference. If the absolute value is 1, the plane is parallel to the Y direction.

[0019] According to the above scheme, the identification of the slider hanging table is specifically as follows:

[0020] Identify the plane in the Z direction, determine the surface parallel to the Z direction, take the projection distance from the point on the surface to the highest point of the slider in the Z direction, if a plane has a minimum projection distance and the minimum value is greater than 0, and the position is lower than the side of the slider hanging table, then this surface is confirmed as the slider hanging table surface.

[0021] According to the above scheme, the plane parallel to the Z direction is determined by multiplying the plane direction by the Y direction of the slider reference. If the absolute value is 1, the plane is parallel to the Z direction.

[0022] According to the above scheme, the specific inclined guide post hole is confirmed according to the slider reference:

[0023] Determine whether the cylindrical through hole surface identified in the slider reference is closed. If the cylindrical through hole surface is closed, it is confirmed to be an inclined guide post hole surface, and the through hole is an inclined guide post hole.

[0024] According to the above scheme, the identification of the threaded hole and the groove where the threaded hole is located is specifically as follows:

[0025] Take a non-closed circular hole surface from the collected surfaces, and take an arc at a certain height of the circular hole surface. If the central angle of the arc is 270°, the arc is considered to be a threaded hole, and the groove where the threaded hole is located is identified based on a set of symmetrical planes.

[0026] A computer storage medium stores a computer program executable by a processor, wherein the computer program executes the above-mentioned method for automatic slider labeling.

[0027] The beneficial effects produced by the present invention are:

[0028] The present invention can realize automatic recognition and marking of key dimensions of the slider, such as the slider hanging platform, inclined guide column holes, threaded holes, etc., by automatically identifying the features of the slider, thereby avoiding designers spending a lot of time on projection and dimension marking, repeating labor without creative meaning, and also avoiding human errors during marking, thereby improving work efficiency.

[0031] Figure 3 2 is another slider dimensioning diagram according to an embodiment of the present invention. DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] When the slider is processed, its key parameters need to be marked. This can be determined through customer experience, that is, the processing scenario. The key parameters that need to be marked are summarized as: slider hanger, inclined guide column hole, and threaded hole (for locking the wear-resistant block).

[0034] In order to improve the efficiency of marking key parameters of a slider, the present invention provides a method for automatically marking a slider, such as Figure 1 As shown, the following steps are included:

[0035] S1. Collect the surface of the slider and determine the slider reference.

[0036] In the process of drawing, the benchmark is crucial. Correct benchmark identification is the basis of processing parameters. When identifying the slider benchmark, first analyze the surface information on the solid model, including the type of surface, the direction of the surface, and the points of the surface. The collected surface types are plane and cylindrical.

[0037] Analyze the cylindrical surface, take the complete cylindrical surface in the surface, and use the ray method to use the surface direction to determine that this cylindrical surface is a through hole, and preliminarily identify it as the feature of the inclined guide column hole. This cylindrical surface is considered to be a cylindrical through hole surface; analyze the plane, and use the direction perpendicular to the plane direction and the direction of the cylindrical through hole surface as the X provisional direction of the slider reference, and obtain the Y provisional direction and Z provisional direction of the slider reference through the right-hand screw rule; from the X provisional direction and Y provisional direction, select the direction with a smaller angle with the cylindrical tilt direction as the X direction of the slider reference, and find the plane direction that is symmetrical and perpendicular to the X direction at the same time, and obtain the Y direction of the slider reference. The Z provisional direction is confirmed as the Z direction. At this time, the slider reference is determined to facilitate the subsequent projection of the slider view and dimension information annotation.

[0038] S2. Obtain the slider plane information according to the slider reference and identify the side of the slider hanging platform.

[0039] The slider's hanging platform needs to be processed, so it is particularly important to identify the slider's hanging platform. Generally speaking, the slider's hanging platform is a plane, so the plane and plane information are obtained according to the reference determined by S1. The plane direction is multiplied by the Y direction of the slider's reference. The absolute value is 1, which is the plane parallel to the Y direction. The plane parallel to the Y direction is judged; the projection distance from the point on the plane parallel to the Y direction to the highest point of the slider in the Y direction is taken. If a plane has a minimum projection distance and the minimum value is greater than 0, then this plane is confirmed as the side of the slider hanging platform. The same method is used to find the symmetrical side of the hanging platform.

[0040] S3. According to the identified side of the slider hanging platform, identify the hanging platform surface and mark it.

[0041] After identifying the side of the platform, the plane direction is multiplied by the Y direction of the slider reference. The absolute value is 1, which is the plane parallel to the Z direction. The projection distance in the Z direction from the point on the plane parallel to the Z direction to the highest point of the slider is taken. If a plane has a minimum projection distance and the minimum value is greater than 0, and the position is lower than the side of the slider platform, then this surface is confirmed as the slider platform surface.

[0042] S4. Confirm the inclined guide post hole according to the slider reference and mark it.

[0043] In S1, the characteristics of the inclined guide pin hole are preliminarily confirmed. In this step, the cylindrical through hole surface identified in S1 is judged. If it is a closed cylindrical through hole surface, it is judged as an inclined guide pin hole surface, and the through hole is confirmed to be an inclined guide pin hole. After the inclined guide pin hole is identified, a cross-sectional view of the inclined guide pin hole is displayed on the main view, and the size information and position information of the inclined guide pin hole are marked.

[0044] S5. Identify the threaded holes and the grooves where the threaded holes are located based on the collected surfaces of the sliders and mark them.

[0045] Take a non-closed circular hole surface from the collected surfaces, and take an arc at a certain height of the circular hole surface. If the central angle of the arc is 270°, the arc is considered to be a threaded hole. When marking the position information, it is also necessary to identify the information of the groove where the threaded hole is located, and lock the groove where the threaded hole is located based on a set of symmetrical planes.

[0046] like Figure 2 and Figure 3 As shown, the present invention can realize automatic marking of key dimensions of the slider such as the slider hanging platform, inclined guide post hole, threaded hole, etc. by automatically identifying the slider features, thereby avoiding designers spending a lot of time on projection and dimension marking, repeating labor without creative meaning, and avoiding manual errors during marking, thereby improving work efficiency. Figure 2 and Figure 3 Only an automatic annotation effect diagram is provided. The dimensions annotated in the diagram are neither within the protection scope of the present invention nor related to the protection scope of the present invention, and therefore are blurred.

[0048] The order of execution of each step in the above embodiment does not mean the order of execution. The order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present application.

[0049] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
