Description

Technical Field

[0001] The present invention relates to the technical field of gear processing and production, and more specifically, to a gear processing device and method for a gear processing machine tool with curved surface detection. Background Art

[0002] During the machining process, it is usually difficult for gear machining machines to detect and correct machining errors in real time, which makes it difficult to effectively guarantee machining accuracy, thus affecting the quality of the final product. Traditional gear machining equipment usually relies on preset machining paths and parameters, and cannot monitor the surface changes of the tooth shape in real time during the machining process. This technical defect will cause machining errors to gradually accumulate, making it difficult to detect and correct them in time.

[0003] In actual production, gear machining errors may be caused by a variety of factors, such as tool wear, machine tool vibration, or uneven material hardness. Since traditional processing equipment lacks real-time detection capabilities, errors usually have to wait until after processing to be discovered through offline detection methods. This delayed detection method not only affects production efficiency, but may also lead to an increase in scrap rate. For high-precision gear manufacturing, especially in high-end manufacturing fields such as aviation and automobiles, the timeliness of error adjustment is crucial. Due to the inability to respond to error adjustments in real time during the processing process, traditional machine tools show obvious deficiencies in dealing with processing error problems in complex gear processing.

[0004] In addition, as modern industry's requirements for gear accuracy and processing efficiency increase, the limitations of traditional processing methods are becoming more and more obvious. For high-precision gears, the control of subtle parameters such as tooth curvature, pitch error, and surface finish is the key to determining product quality. However, machine tools that lack surface detection functions cannot dynamically adjust cutting parameters during processing to ensure that the final processing results meet design requirements. Therefore, the technical defects of existing gear processing equipment are not only limited in accuracy, but also difficult to adapt to the comprehensive requirements of modern manufacturing for flexibility, efficiency, and quality.

DETAILED DESCRIPTION

[0054] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0055] Example 1: Please refer to Figure 1-3 The present invention provides a technical solution: a gear processing machine tool with curved surface detection gear processing equipment, including: a gear processing end 100, a curved surface analysis module 200, a control module 300 and a feedback adjustment module 400; each module is connected by wire or wireless;

[0056] The gear processing end 100 is used for fixing the gear with a limiting assembly 110. The limiting assembly 110 is provided with a curved surface processing area 111 for gear curved surface processing and a curved surface detection area 112 for video acquisition. A retractable tool system 120 is provided in the curved surface processing area 111. A curved surface detection device 150 is vertically provided in the curved surface detection area 112.

[0057] Specifically, the tool system 120 includes a tool, a spindle assembly that drives the tool to cut, and a spindle motor that drives the spindle assembly; the spindle motor acts on the tool through the spindle assembly, and when the tool is needed to process the gear, the tool cutting speed can be controlled by controlling the spindle speed parameter of the spindle motor, and the gear processing at different stages can be adjusted by the tool cutting speed; the tool feed amount and tool cutting depth can be controlled by controlling the tool feed parameter; the tool motion state is determined by determining the cutting path data;

[0058] The tool includes a profile milling cutter, a gear hobbing cutter or a gear shaping cutter specifically for gear machining. The tool feed rate, tool cutting depth and tool motion state determine the volume of material removed by cutting at the current tool cutting speed; thereby determining the specific cutting operation to be performed on the gear.

[0059] like Figure 2 As shown, the tool includes a main tool 121 for performing gear cutting and auxiliary grinding tools 122 arranged on both sides of the main tool 121; the angle between the grinding tool 122 and the main tool 121 is determined according to the tool feed parameters, and the grinding tool 122 is provided with a grinding plate at one end facing the gear, and the grinding tool 122 is provided with an elastic plate at the other end facing away from the gear. When the main tool 121 is cutting the gear, the grinding tool 122 is grinding the cutting edge at the same time. The use of the elastic plate can avoid excessive grinding of the grinding tool 122 and reduce the possibility of wear.

[0060] The cutting logic of the tool system 120 is:

[0061] Determine the target design parameters of the tool system based on the preset design drawings; and collect the cutting processing data of the tool system, wherein the cutting processing data includes cutting path data, tool feed parameters and spindle speed parameters;

[0062] The gear to be processed is fixed at a processing position, and the tool system 120 acts on the gear to be processed at a preset position to process the gear, obtain cutting path nodes during the gear processing, and organize continuous cutting path nodes into cutting path data;

[0063] The cutting path data is compared and analyzed with the target design parameters. If the cutting path data is inconsistent with the target design parameters, the tool feed parameters of the tool are controlled by adjusting the spindle speed parameters to make the cutting path data consistent with the target design parameters.

[0064] The limit assembly 110 and the tool system 120 are arranged in a grinding cavity 130, and a consumable protection part 140 and a surface detection device 150 are arranged in the grinding cavity 130; based on the purpose of the consumable protection part 140 to protect the gear processing end 100, the surface detection device 150 sends the collected gear surface information to the surface analysis module 200, and the gear processing end 100 is fixed by a positioning pin 160. In addition, it should be noted that the other specific processing structures in the processing module are the existing technology in this field, so a detailed description of the specific mechanical structure is not given.

[0065] In short, the processing module is the core unit for performing cutting tasks in the gear processing equipment, and ensures high-precision cutting of the gear through the coordinated work of the spindle motor and the tool system 120. The module is combined with the control module 300 to dynamically adjust the processing parameters to achieve automated and efficient gear processing.

[0066] The surface analysis module 200 detects the gear surface information in the gear processing process in real time based on the surface detection device 150; and sends the gear surface information to the control module 300;

[0067] Specifically, the surface detection device 150 includes an optical detection system, a laser scanner and a three-dimensional profiler. The logic for obtaining the gear surface information is as follows:

[0068] The gear detection area and the gear rotation angle are determined based on the position of the limit assembly 110 where the curved surface detection area 112 is located. After the gear rotates a certain angle, the gear surface is sampled in different directions through multiple curved surface detection areas 112;

[0069] Determine gear design parameters based on the gear surface image, wherein the gear design parameters include tooth curvature, spacing between adjacent teeth, surface roughness and grinding marks; compare the gear design parameters with the target design parameters in real time to determine abnormal surface points and depth information of the abnormal surface points;

[0070] It should be noted that: in the process of analyzing the preset design drawings, the control parameters related to gear processing all correspond to a standard parameter, which is merged and integrated into the target design parameters through the standard parameters.

[0071] The gear surface image and the abnormal surface points corresponding to the gear surface image and the depth information of the abnormal surface points are marked as gear surface information, and the data acquisition frequency corresponding to the surface detection device 150 is preset based on the gear processing speed, and the gear surface information is collected based on the data acquisition frequency.

[0072] It should be noted that the detection module integrates a variety of high-precision sensors, combined with real-time data transmission and feedback adjustment functions, so that the surface detection in the gear processing process meets the requirements of high efficiency and high precision. This technology greatly improves the processing efficiency and product quality, and meets the needs of modern high-precision gear manufacturing; through the combined use of optical detection systems, laser scanners and three-dimensional profilers, the surface data of gears can be detected at micron-level accuracy, greatly improving the processing accuracy; the real-time linkage of the surface analysis module 200 and the control module 300 ensures that the system can respond to errors in processing in a timely manner, quickly make dynamic adjustments, and reduce the unqualified rate; the surface detection device 150 adopts a non-contact detection method, without any physical contact with the gear processing surface, and will not introduce new errors; all detection data can be stored and tracked, providing data support for subsequent quality control and process improvement.

[0073] Specifically, the optical inspection system: uses a high-resolution camera or other optical equipment to take real-time photos of the gear surface, captures the gear surface contour, and uses image processing technology to extract key geometric features on the gear surface from the image to determine whether the tooth shape meets the design requirements;

[0074] Laser scanner: uses a laser beam to illuminate the gear surface and measures the height and shape of each point on the gear surface based on the time difference or phase difference of the reflected echo signal. Laser scanners provide high measurement accuracy and are used to detect tiny surface changes of gears in real time.

[0075] 3D profiler: It uses laser, white light interference or grating projection technology to obtain the 3D topography data of the gear surface in real time and express the surface profile in precise digital form.

[0076] The control module 300 analyzes the machining error based on the gear surface information, calculates the corresponding adjustment parameter based on the machining error, and dynamically adjusts the cutting machining data based on the adjustment parameter so that the gear machining meets the preset machining standard and error threshold.

[0077] Specifically, the analysis logic of the processing error is:

[0078] The gear surface information is compared and analyzed with the target design parameters, and the nodes where the gear surface information is inconsistent with the target design parameters are extracted as abnormal surface points. The coordinates of the abnormal surface points are ; The coordinates of the target design parameters corresponding to the abnormal surface points are ; The machining error is expressed by the three-dimensional Euclidean distance, and the machining error is:

[0079] ,

[0080] The processing error The error threshold is set Conduct comparative analysis,

[0081] like , it is judged that there is a processing deviation at the abnormal surface point and the processing parameters need to be adjusted; error threshold Set according to processing requirements and calculate processing compensation value according to preset proportional gradient ;

[0082] ;

[0083] Wherein: K is the preset ratio. The machining compensation value is repeatedly verified by adjusting the preset ratio gradient until the optimal machining compensation value is determined, thereby forming the basis for dynamically adjusting the cutting machining data.

[0084] The logic of dynamically adjusting the cutting processing data based on the adjustment parameters is:

[0085] Before the machining begins, the cutting machining data of the tool system is determined according to the target design parameters corresponding to the preset design drawings, the gear to be machined is clamped on the workpiece fixture, the spindle is driven to rotate according to the spindle speed parameter, and the tool system 120 is rotated at high speed according to the tool feed parameter;

[0086] According to the preset cutting path data, the tool system 120 is controlled to move relative to the workpiece to complete the layer-by-layer cutting of the gear tooth profile. During the layer-by-layer cutting process, the surface detection device 150 is used to detect abnormal surface points and their depth information in real time.

[0087] If the depth information of the abnormal surface point is less than the error threshold, it means that there is a deviation in the gear surface processing. Cutting compensation is performed by automatically adjusting the tool feed parameters and spindle speed parameters until the gear processing error meets the preset standard.

[0088] If the depth information of the abnormal surface point is greater than or equal to the error threshold, it means that the gear surface processing deviates from the normal position. The tool motion path is dynamically adjusted by adjusting the cutting path data to correct the cutting path in time.

[0089] The adjustment formula for the cutting path is:

[0090] ;

[0091] in: represents the modified gear surface point; Indicates the abnormal surface point currently detected; Indicates the machining compensation value of abnormal surface points;

[0092] After processing is completed, the spindle stops rotating, the tool returns to the preset position, the workpiece is taken out of the fixture, and the processed gear is finally inspected until the processing error of the gear meets the preset standard.

[0093] It should be noted that the control module 300 is connected to the surface analysis module 200, and can quickly feed back the processing results and adjustment parameters to the gear processing end 100 to achieve dynamic adjustment of parameters; the high-performance processor and intelligent algorithm integrated in the control module 300 can process the detection data in real time and efficiently, accurately analyze the processing errors and dynamically adjust the processing parameters to ensure high precision and high efficiency of gear processing. Through the combination of error detection formula, compensation formula and adaptive processing algorithm, the control module 300 realizes the full control and optimization of the processing process.
