Description

Technical Field

[0001] The present invention relates to the field of mechanical manufacturing, and more particularly to a new method for processing and detecting end face grooves. Background Art

[0002] During the machining of end face grooves on shafts, the end face grooves are generally composed of compound angles, and the diameter size cannot be directly measured. It depends entirely on the equipment and procedures, and the final machining result is the same size. There is no way to control the diameter size during the machining process, and it is difficult to ensure product quality.

[0003] In addition, the final diameter size of the end face groove can only be detected by using cement and a projector after machining is completed, and the diameter size cannot be monitored during the process.

[0004] To solve this problem, a right-angled triangle is constructed during processing, and the cusp principle is used to completely control the starting diameter. Then, a new method of controlling the diameter size is converted into controlling the length size through trigonometric functions. The length direction is easy to measure, and the diameter size of the end face groove during the processing process is better guaranteed. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] In response to the problems existing in the prior art, the purpose of the present invention is to provide a new method for processing and detecting end face grooves, which can be achieved by setting a diameter triangle during processing and utilizing the cusp principle of a right-angled triangle, so that the length direction of the end face groove is easy to measure, and the diameter size of the end face groove during the processing is better guaranteed, thereby avoiding the situation in which the end face groove is scrapped due to low accuracy of the inner diameter size of the end face groove during the processing.

[0007] 2. Technical solution

[0008] To solve the above problems, the present invention adopts the following technical solutions.

[0009] A new method for processing and detecting end face grooves includes the following steps:

[0010] S1. Select and clamp the workpiece and tool and debug: Select the slotting turning tool according to the type of end face groove to be opened, and clamp the workpiece and turning tool. During the installation process, adjust the turning tool position according to the actual size requirements of the end face groove;

[0011] S2. Flattening the end surface: Process the specified workpiece and flatten the end surface of the workpiece;

[0012] S3. Constructing a diameter triangle: Construct a diameter triangle on the workpiece and use the cusp principle of a right triangle to completely control the starting diameter. Then, use the trigonometric formula to convert the controlled diameter size into the controlled length size.

[0013] S4. Grooving to control the total length and chamfering: The length dimension is effectively controlled by constructing a teaching triangle, and a groove is opened on the end face of the workpiece. After the groove is opened to the actual total length, the end face is cut and chamfered.

[0014] S5. Detecting the dimensional accuracy of the slotting diameter: After the slotting is completed, the slotting diameter is subsequently detected to determine the processing dimensional accuracy.

[0015] Furthermore, the principle of the cusp point of the right triangle in S3 is: no matter how many times it is cut parallel to the hypotenuse, the axial diameter of the point remains unchanged, thereby controlling the starting point diameter φD2.

[0016] Furthermore, the trigonometric function formula in S3 is: φD=φD2-2*b*tanα. The formula is used to convert the measured diameter into the measured length. b can be measured at any time during the processing. b is the length of the straight side of the right triangle to better ensure the diameter size φD.

[0017] Furthermore, during the tool alignment in S1, during the installation of the turning tool, the tip of the turning tool is aligned with the rotation center position of the workpiece processing end face, and the center line of the turning tool should be parallel to the axis line of the workpiece during the tool installation.

[0018] Furthermore, the detection tool in S5 is one of a vernier caliper, a vernier depth gauge, and a sample measuring tool.

[0019] Furthermore, the blade length of the turning tool selected in S1 is greater than the depth of the end face groove.

[0020] Furthermore, the grooving in S4 requires rough turning and finish turning, and the tool used for the finish turning is a high-speed steel turning tool.

[0021] 3. Beneficial effects

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] (1) This solution makes it easy to measure the length direction of the end face groove by setting a diameter triangle during processing and using the cusp principle of a right triangle, and better guarantees the diameter size of the end face groove during processing, avoiding the situation in which the end face groove is scrapped due to low accuracy of the inner diameter size of the end face groove during processing.

[0024] (2) This solution uses the diameter triangle set during processing to ensure the accuracy of the end face groove diameter φD by utilizing the cusp principle of the right triangle. Therefore, after processing is completed, when the diameter size of the processed end face is subsequently inspected again, accurate inspection data can be obtained.

[0025] (3) This solution can measure the end face groove diameter φD at any time during the processing process. Therefore, during processing, the end face diameter of the workpiece can be detected and controlled in real time, thereby effectively ensuring product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Example 1:

[0031] See also Figure 1-3 A new method for processing and detecting end face grooves includes the following steps:

[0032] S1. Select and clamp the workpiece, tool and debug: Select the slotting turning tool according to the type of end face groove to be opened, and clamp the workpiece and turning tool. During the installation process, adjust the turning tool position according to the actual size requirements of the end face groove. The blade length of the turning tool should be greater than the depth of the end face groove. During the installation of the turning tool, the turning tool tip should be aligned with the rotation center of the workpiece processing end face to prevent the turning tool edge from changing the back angle on both sides due to wear. When installing the tool, the center line of the turning tool should be parallel to the axis line of the workpiece, so as to ensure the correct angle of the secondary deflection angle on both sides and the straightness of the end face groove bottom.

[0033] S2. Flattening the end surface: Process the specified workpiece and flatten the end surface of the workpiece;

[0034] S3. Constructing a diameter triangle: Construct a diameter triangle on the workpiece and use the cusp principle of a right triangle to fully control the starting point diameter;

[0035] The cusp principle of a right triangle: no matter how many times you cut parallel to the hypotenuse, the axial diameter of the point remains unchanged, thus controlling the starting diameter φD2. The controlled diameter size is then converted into the controlled length size through the trigonometric formula.

[0036] The trigonometric formula is: φD=φD2-2*b*tanα. The formula is used to convert the measured diameter into the measured length. b can be measured at any time during the processing. b is the length of the straight side of the right triangle to better ensure the diameter size φD;

[0037] By constructing a right triangle and using the cusp principle to completely control the starting point diameter, a new method is proposed to convert the controlled diameter size into the controlled length size through trigonometric functions. The length direction is easy to measure, and the diameter size of the groove is better guaranteed. When machining the end face groove, the end face groove diameter φD can be detected and controlled during the machining process, making up for the problem of post-measurement, and the end face groove diameter φD can be guaranteed by the machining principle.

[0038] S4. Grooving to control the total length and chamfering: The length dimension is effectively controlled by constructing a teaching triangle, and the groove is opened on the end face of the workpiece. After the groove is opened to the actual total length, the end face is cut and chamfered. When processing the end face groove, the groove side and groove bottom are required to be straight and clear. Rough turning and fine turning are required during the grooving process. The tool used for fine turning is a high-speed steel turning tool.

[0039] S5. Detection of slotting diameter accuracy: After slotting is completed, the slotting diameter is subsequently detected to determine the processing size accuracy and to reduce the need to detect the final diameter size through mastic and projector. The diameter size can be monitored in real time during the production process and is convenient for detection of the diameter size. The detection tool is a vernier caliper, a vernier depth gauge, or a sample measuring tool.

[0040] During use: clamp and fix the workpiece and tool separately, and adjust the tool and processing program according to production needs after completion.

[0041] After the adjustment is completed, a diameter triangle is planned and constructed on the workpiece according to mathematical geometry to assist in end face groove processing.

[0042] After processing is completed, the slot diameter is inspected to determine the processing dimensional accuracy.

[0043] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
