TECHNICAL FIELD

[0001] The present application relates to the technical field of turning processing, in particular to an eight-station rotary table turning, drilling and tapping special machine device and a control method thereof. BACKGROUND

[0002] Turning equipment is the core basic equipment for realizing metal cutting processing. Through driving the workpiece to rotate at high speed, the workpiece is gradually processed into a finished product or a semi-finished product meeting the requirements of size accuracy and shape by cooperating with the precise feeding and cutting action of the tool.

[0003] In the related art, the traditional turning equipment takes the workpiece rotation as the main motion form, and realizes cutting through the linear or curved feeding of the tool, which can complete basic processing operations such as external circle, internal hole, end face and thread.

[0004] According to the related art in the above, the inventor believes that the traditional turning equipment has a single function, and can only perform the same processing mode on the workpiece to be processed in a single use, and then needs to be transported to the next processing equipment position for processing. The whole cycle is relatively long, and a large amount of manual labor is required, and the processing efficiency is low. SUMMARY

[0005] In order to improve the processing efficiency of the turning equipment, the present application provides an eight-station rotary table turning, drilling and tapping special machine device and a control method thereof.

[0006] In the first aspect, the present application provides an eight-station rotary table turning, drilling and tapping special machine device, which adopts the following technical scheme:

[0008] The base is provided with eight stations, the machining device is arranged on the station one by one to perform different kinds of machining on the workpiece, the moving assembly is arranged on the station to control the movement of the machining device, the rotary table is arranged in the center of the base and is rotationally connected with the base, and the claw disc is arranged on the rotary table and is used to clamp the workpiece and is one-to-one corresponding to the machining device.

[0009] Through the above technical scheme, the eight stations can realize multi-process synchronous machining, the machining devices of different stations have clear division of labor, can complete turning, drilling and tapping and other machining operations, and the processing efficiency of the equipment is improved. The moving assembly can flexibly adjust the position of the machining device to adapt to the processing needs of different sizes of parts. The cooperation of the rotary table and the claw disc realizes the accurate transfer of the parts between the stations, the one-to-one corresponding design of the claw disc ensures the stability of the part clamping, the overall structure is compact, the parts work cooperatively, and the efficiency and automation degree of the turning, drilling and tapping processing are greatly improved.

[0010] Optionally, the turntable is further provided with a servo indexing assembly for realizing high-precision positioning and a brake pad for protecting the claw disc.

[0011] The servo indexing assembly and the claw disc are fixedly connected to control the free rotation of the claw disc, and the brake pad is fixedly connected to the claw disc.

[0012] By adopting the above technical solution, the servo indexing assembly can accurately control the rotation angle of the claw disc by virtue of the high-precision driving characteristics of the servo motor, especially suitable for high-precision curved surface machining and multi-station coaxiality machining scenarios with high requirements. The fixed connection design of the brake pad and the claw disc not only avoids the dimensional deviation caused by the displacement of the workpiece during machining, but also reduces the impact loss of the mechanical structure of the claw disc, prolonging the service life of the core components of the equipment.

[0013] Optionally, it further comprises a transmission assembly provided on the turntable for transmitting current and an electromagnetic valve assembly provided on the turntable for controlling the power supply of the machining device.

[0014] The transmission assembly comprises an electric wire for power transmission, a fixing piece fixedly connected with the electric wire to fix the electric wire, a conductive ring fixedly connected with the fixing piece to conduct electricity, and a power transmission cylinder rotationally connected with the conductive ring to transmit power.

[0015] The end of the power transmission cylinder away from the conductive ring is fixedly connected with the turntable to rotate together with the turntable.

[0016] By adopting the above technical solution, the transmission assembly adopts the rotating conductive structure of the conductive ring and the power transmission cylinder, solving the problem of easy entanglement of the electric wire with the turntable in traditional turntable equipment, realizing the continuous and stable transmission of current to the moving parts such as the claw disc, the servo indexing assembly, etc. on the turntable, and the electromagnetic valve assembly is integrated on the turntable, which can directly receive the controller command to control the power supply of the machining device, adapting to the high-frequency working condition requirement of eight-station continuous operation.

[0017] In the second aspect, the present application provides a control method of an eight-station turntable turning, drilling and tapping special machine, which adopts the following technical solution:

[0018] A control method of an eight-station turntable turning, drilling and tapping special machine, comprising:

[0019] Step S1: In response to a start signal, obtaining machining information of a part to be machined;

[0020] Step S2: Analyzing the machining information to obtain machining size and machining type;

[0021] Step S3: Determining the machining device number based on the machining type;

[0022] Step S4: Determining the machining path based on the machining size and the machining type;

[0023] Step S5: controlling the machining device corresponding to the machining device number to perform machining along the machining path, and outputting a preset machining completion signal after the machining is completed;

[0024] Step S6: after all machining completion signals are output, controlling the turntable to rotate according to a preset sub-station angle, and then continuing to execute step S5;

[0025] Step S7: stopping working when a preset end signal is received.

[0026] By adopting the above technical solutions, automatic machining control based on part information to be machined is realized, and through the step-by-step machining mode of the eight-station turntable, multiple parts can be machined in different processes at the same time, which greatly improves the machining efficiency, and through the correspondence between the machining device number and the machining path, the accuracy of the machining process is ensured, the overall process is coherent and efficient, and the batch machining demand is met.

[0027] Optionally, it further comprises:

[0028] Step S70: obtaining the finished product size of the part to be machined after machining is completed;

[0029] Step S71: analyzing the difference area based on the finished product size and the preset sample size;

[0030] Step S72: when the difference area exists, determining the abnormal machining device number according to the difference area and the machining path;

[0031] Step S73: outputting the abnormal machining device number and a preset abnormal alarm signal.

[0032] By adopting the above technical solutions, closed-loop monitoring of machining quality is realized, and by comparing the finished product size with the sample size, machining abnormalities can be found in time, and when there is a difference area, the abnormal machining device can be accurately located, which facilitates rapid troubleshooting and reduces the generation of unqualified products. At the same time, the abnormal alarm signal reminds the operator to handle in time, which ensures the stability of the machining process.

[0033] Optionally, the method of determining the abnormal machining device number according to the difference area and the machining path comprises:

[0034] Step S720: determining the same machining position based on the machining path corresponding to the different machining device numbers;

[0035] Step S721: when the difference area and the same machining position have an intersection, defining the corresponding machining device number as a suspected machining device number, and defining the corresponding machining path as a suspected machining path;

[0036] Step S722: randomly selecting one suspected processing device number, and determining different processing positions based on the corresponding suspected processing path and the same processing position;

[0037] Step S723: when the different processing positions exist, and the difference area and the different processing positions also exist intersection, defining the corresponding suspected processing device number as the abnormal processing device number for output;

[0039] Step S725: when the different processing positions do not exist, defining the corresponding suspected processing device number as the abnormal processing device number for output.

[0040] By adopting the above technical scheme, the suspected device is screened through the same processing position, and then further verified by combining the intersection condition of the different processing positions and the difference area, so as to gradually exclude the interference items, finally determine the abnormal processing device number, improve the accuracy of abnormal positioning, avoid the shutdown or rework caused by misjudgment, and improve the fault handling efficiency.

[0041] Optionally, the method for outputting the abnormal processing device number and the preset abnormal alarm signal comprises:

[0042] Step S730: controlling the processing device corresponding to the abnormal processing device number to stop working;

[0043] Step S731: determining the similar processing device number of the same processing type based on the abnormal processing device number, and defining the processing path corresponding to the abnormal processing device number as the abnormal processing path;

[0044] Step S732: determining the sequence based on the abnormal processing device number and the similar processing device number;

[0045] Step S733: controlling the processing device corresponding to the similar processing device number to process along the corresponding processing path and the abnormal processing path according to the sequence, and outputting the processing completion signal after the processing is completed, without outputting the abnormal processing device number and the preset abnormal alarm signal;

[0046] Step S734: outputting the abnormal processing device number and the preset abnormal alarm signal when the similar processing device number does not exist.

[0047] By adopting the technical scheme, when the abnormal machining device is detected, the similar machining device is preferentially enabled to replace machining, the machining process is ensured not to be interrupted, the production stagnation loss is reduced, and the alarm is triggered only when there is no similar device, so that the production continuity and the timeliness of fault processing are balanced.

[0048] Optionally, the method for controlling the similar machining device number to process along the machining path and the abnormal machining path according to the sequence includes:

[0049] Step S7330: defining the machining path corresponding to the similar machining device number as a similar machining path;

[0050] Step S7331: determining an intermediate machining device number based on the similar machining device number and the abnormal machining device number, and defining the machining path corresponding to the intermediate machining device number as an intermediate machining path;

[0051] Step S7332: determining the relevance based on the intermediate machining path, the similar machining path and the abnormal machining path;

[0052] Step S7333: determining the rotation angle based on the intermediate machining device number and the similar machining device number;

[0053] Step S7334: when the relevance is the preset necessary sequence, defining the machining path processed first in the sequence as a first machining path, and defining the machining path processed last as a second machining path;

[0054] Step S7335: identifying a first completed path of the part to be machined at the station corresponding to the similar machining device number, and a second completed path at the station corresponding to the intermediate machining device number;

[0055] Step S7336: if the first completed path does not include the first machining path, controlling the similar machining device to process according to the first machining path;

[0056] Step S7337: after controlling the similar machining device number to process according to the first machining path, controlling the turntable to rotate according to the rotation angle;

[0057] Step S7338: if the first completed path includes the first machining path and the intermediate machining path, controlling the similar machining device to process according to the second machining path;

[0058] Step S7339: if the first completed path includes the first machining path but does not include the intermediate machining path, controlling the turntable to rotate according to the rotation angle;

[0059] Step S7340: If the second completed path does not include the first machining path, the control controls the rotating disc to rotate according to the rotating angle.

[0060] Step S7341: If the second completed path includes the first machining path but does not include the intermediate machining path, the control controls the intermediate machining device to machine according to the intermediate machining path.

[0061] Step S7342: If the second completed path includes the first machining path and the intermediate machining path, the control controls the rotating disc to rotate according to the rotating angle.

[0062] By adopting the above technical solution, the logic of replacing machining by similar machining devices is refined, the relevance and sequence requirements of machining paths are considered, the completed path of the part to be machined is identified, the machining steps and the rotating timing of the rotating disc are dynamically adjusted, the replacement machining process is ensured to meet the process requirements, and machining defects caused by process disorder are avoided.

[0063] Optionally, the method for controlling the machining device numbered machining device to machine along the machining path and outputting the preset machining completion signal after machining is completed includes:

[0064] Step S50: Identifying the current completed path of the part to be machined on the work station corresponding to the machining device number;

[0065] Step S51: When the current completed path contains the machining path or the current completed path does not exist, directly outputting the machining completion signal;

[0066] Step S52: When the current completed path does not contain the machining path, controlling the machining device numbered machining device to machine along the machining path;

[0067] Step S53: Outputting the preset machining completion signal after machining is completed.

[0068] By adopting the above technical solution, intelligent judgment of the machining process is realized, repeated operation on the machined path is avoided, invalid machining time is reduced, machining efficiency is improved, and at the same time, accurate machining control of the uncompleted path is realized, ensuring that each process is completed according to the requirements, and ensuring the consistency of the machining quality.

[0069] Optionally, the method for obtaining the machining information of the part to be machined further includes:

[0070] Step S10: After obtaining the machining information of the part to be machined, analyzing the machining information to identify the text content thereof;

[0071] Step S11: Judging the text content according to the preset machining information database to obtain the correctness of the machining information;

[0072] Step S12: if the correctness is correct, input the information to be processed.

[0073] By using the above technical scheme, the information to be processed is identified and its correctness is confirmed, so that the incorrect or conflicting information to be processed is avoided from being input into the equipment, the equipment is prevented from being damaged in the processing process, and the safety is improved.

[0074] In summary, the present application has at least one of the following beneficial technical effects:

[0075] The step-by-step processing mode of the eight-station turntable allows multiple parts to be processed synchronously in different processes, improving the work efficiency of the equipment in processing parts;

[0076] By automatically searching for abnormal processing devices and using similar processing devices to process abnormal processing paths, the processing process does not need to stop for maintenance due to the failure of a single device, ensuring the continuity of batch production;

[0077] The transmission assembly prevents the wires from being entangled together during the operation of the equipment, avoiding safety problems caused by wire entanglement. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0083] The present application will be further described in detail below with reference to the drawings and embodiments.

[0084] The embodiments of the present application disclose a control method of an eight-station turntable turning and drilling machine.

[0085] Referring toFigure 1 A control method of an eight-station rotary table turning, drilling and tapping special machine comprises the following steps:

[0086] Step S1: In response to a start signal, obtain the to-be-processed information of the to-be-processed part.

[0087] The start signal refers to an instruction signal for triggering the equipment to enter the processing state. The start signal is manually triggered by the staff, such as pressing the start button on the equipment. The to-be-processed part refers to the part that needs to be processed by the equipment. The to-be-processed information refers to the information describing the processing requirements of the to-be-processed part, including the part material, geometric parameters (such as outer diameter, length, hole diameter), processing procedures (such as turning, drilling, tapping), precision requirements, etc. The to-be-processed information is input into the equipment by the staff in advance.

[0088] Step S2: Analyze the to-be-processed information to obtain the processing size and processing type.

[0089] The processing size refers to the specific geometric size parameter that the to-be-processed part needs to reach, including diameter, length, hole diameter, groove depth, thread specification, etc. The processing type refers to the specific processing procedure type performed on the to-be-processed part, such as turning an outer circle, turning an end face, drilling, tapping, etc. The implementation means is that the equipment extracts the parameters of the to-be-processed information through a preset data format protocol (such as JSON), thereby obtaining the processing size and processing type.

[0090] Step S3: Determine the processing device number based on the processing type.

[0091] The processing device number refers to the number corresponding to the processing device 2 on each station of the equipment. The implementation means is that the equipment numbers the processing device 2 through the preset processing means (such as turning, drilling, etc.) that each processing device 2 can implement.

[0092] Step S4: Determine the processing path based on the processing size and the processing type.

[0093] The processing path refers to the movement trajectory and action sequence of the tool or processing component when the processing device 2 processes the to-be-processed part, including the starting point, the ending point, the path trajectory (such as a straight line, a circular arc), the feeding sequence (such as turning an end face first and then turning an outer circle), etc. The implementation means is that the equipment has a built-in processing path generation module, which generates the processing path of the tool in combination with the processing size and the processing type.

[0094] Step S5: Control the processing device 2 corresponding to the processing device number to process along the processing path, and output a preset processing completion signal after processing is completed.

[0095] The machining device 2 refers to a device installed on different stations for machining the parts to be machined, each machining device 2 has its own machining means (such as turning, drilling, etc.). The machining completion signal refers to the state signal sent by the machining device 2 after completing the preset machining path to the equipment, which is used to inform the controller that the current machining path has been completed. The implementation means is that the equipment sends control instructions to the corresponding machining device 2 according to the machining device number, so that the machining device 2 processes the parts to be machined along the machining path, and the position sensor built-in the machining device 2 feeds back the motion position in real time, and when the machining device 2 completes the machining path, the feedback signal of machining completion is output to the equipment.

[0096] Step S6: After all the machining completion signals are output, the control disc 4 is rotated according to the preset sub-station angle, and then step S5 is continued.

[0097] The sub-station angle refers to the angle between adjacent two stations when the disc 4 rotates, which is input by the staff into the equipment in advance. After all the machining completion signals are output, it means that the machining device 2 in each station has completed its own machining path for the corresponding parts to be machined, and the equipment can control the disc 4 to rotate the preset sub-station angle, so that each part to be machined is processed subsequently.

[0098] Step S7: When the preset end signal is received, stop working.

[0099] The end signal refers to the instruction signal for stopping all machining actions of the equipment, and the end signal is manually triggered by the staff, such as pressing the end button on the equipment.

[0100] Among them, it also includes:

[0101] Step S70: Obtain the finished product size of the part to be machined after machining.

[0102] The finished product size refers to the geometric size parameter actually measured after the part to be machined completes all machining. The implementation means is to set an automatic measuring device, such as a laser diameter measuring instrument, a contact type length measuring instrument, and a three-coordinate measuring probe, etc., at the discharge station of the equipment, and when the machined part is conveyed to the discharge station, the measuring device automatically starts to measure the key size of the finished product.

[0103] Step S71: Analyze the difference area based on the finished product size and the preset sample size.

[0104] The sample size refers to the standard size of the part to be processed after the processing is completed. The difference area refers to the area that exceeds the allowed processing tolerance range when there is a difference between the finished product size and the sample size. For example, the sample size of a processed hole needs to be φ50±0.02mm, and the finished product size is φ49.95mm, the difference between the two is 0.05mm, which has exceeded the allowed tolerance range, so the area of the processed hole of the finished product is judged as the difference area. The implementation means is to compare and calculate the obtained finished product size and sample size one by one through the equipment, and if it is found that there is an area that exceeds the allowed tolerance range, it is judged that the area is a difference area.

[0105] Step S72: When the difference area exists, determine the abnormal processing device number according to the difference area and the processing path.

[0106] The abnormal processing device number refers to the number of the processing device 2 that causes the finished product to have a difference area, i.e., the number corresponding to the malfunctioning processing device 2. The implementation means is that the equipment first determines the area with abnormal processing size according to the difference area, then determines which processing path corresponds to the processing area that produces the difference area according to the processing path corresponding to each processing device 2, and then finds out the corresponding processing device number through the processing path and marks it as the abnormal processing device number.

[0107] Step S73: Output the abnormal processing device number and the preset abnormal alarm signal.

[0108] The abnormal alarm signal refers to the warning signal output by the equipment when it detects a processing abnormality (such as the existence of an abnormal processing device), including audible and visual signals (such as alarm light flashing, buzzer ringing, etc.) and digital signals (such as abnormal processing device number), which are used to remind the operator to handle the abnormality. The implementation means is that the equipment displays the abnormal processing device number on the alarm interface of the equipment operation panel, and controls the alarm light to flash at a preset alarm frequency, and controls the buzzer to emit a preset intermittent ringing, thereby prompting the worker that the processing device 2 has failed.

[0109] The method also includes determining the abnormal processing device number according to the difference area and the processing path, which includes:

[0110] Step S720: Determine the same processing position based on the processing path corresponding to different processing device numbers.

[0111] The same processing position refers to the area in the processing path of different processing devices 2 that processes the same geometric position of the part to be processed. The implementation means is that the equipment analyzes the processing path corresponding to each processing device number by recognizing the preset processing path, and finds out the overlapping part of the processing path.

[0112] Step S721: When the difference region and the same machining position exist intersection, the corresponding machining device number is defined as a suspected machining device number, and the corresponding machining path is defined as a suspected machining path.

[0113] The suspected machining device number refers to the machining device number that is preliminarily determined to possibly cause the difference region. The suspected machining path refers to the machining path corresponding to the suspected machining device number, i.e., the machining path that possibly causes the difference region. The implementation means is that the equipment judges the intersection of the position coordinates of the difference region and the same machining position coordinates. If the coordinates of the difference region coincide with the coordinates of the same machining position, it is determined that there is an intersection. At this time, the device number corresponding to the same machining position is defined as a suspected machining device number, and the corresponding machining path is defined as a suspected machining path.

[0114] Step S722: An arbitrary suspected machining device number is selected, and different machining positions are determined based on the corresponding suspected machining path and the same machining position.

[0115] The different machining position refers to the machining region in the suspected machining path of a certain suspected machining device, except for the same machining position. The implementation means is that the equipment randomly selects a suspected machining number from the suspected machining device number set (a set formed by the previously determined suspected machining device numbers), extracts all machining position coordinates in the path, excludes the coordinates of the same machining position that has been determined, and the remaining coordinates are the different machining positions.

[0116] Step S723: When the different machining position exists, and the difference region and the different machining position also exist intersection, the corresponding suspected machining device number is defined as an abnormal machining device number and is output.

[0117] When the different machining position exists, and the difference region and the different machining position also exist intersection, it indicates that the difference region is located on the machining path of the suspected machining device number corresponding to the different machining position, and it indicates that the suspected machining device is an abnormal machining device. Therefore, the number corresponding to the suspected machining device is an abnormal machining device number. The implementation means is that when the equipment determines that the different machining position exists, the position coordinates of the difference region are compared with the coordinates of the different machining position. When the position coordinates of the difference region and the coordinates of the different machining position exist repeated intersection, it is determined that the different machining position corresponds to the suspected machining device, which is an abnormal machining device, and the corresponding abnormal machining device number is output.

[0118] Step S724: When the different machining position exists, and the difference region and the different machining position do not exist intersection, the suspected machining device number is reselected.

[0119] When the different processing positions exist and the difference area and the different processing positions do not have an intersection, it is indicated that the difference area is not located on the processing path of the suspected processing device number corresponding to the different processing position, the suspected processing device is not an abnormal processing device, the equipment excludes the suspected processing device number from the suspected processing device number set and reselects a suspected processing device number for judgment.

[0120] Step S725: defining the corresponding suspected processing device number as an abnormal processing device number when the different processing positions do not exist, and outputting.

[0121] When the different processing positions do not exist, it is indicated that there is only one processing path on the difference area, and the suspected processing device corresponding to the processing path is an abnormal processing device, and then the control equipment defines the suspected processing device number as an abnormal processing device number and outputs.

[0122] The method further comprises outputting the abnormal processing device number and a preset abnormal alarm signal, and the method comprises the following steps:

[0123] Step S730: controlling the processing device 2 corresponding to the abnormal processing device number to stop working.

[0124] When the abnormal processing device number is determined, the equipment controls the abnormal processing device to stop working, so as to prevent damage to the subsequent parts to be processed.

[0125] Step S731: determining a similar processing device number of the same processing type based on the abnormal processing device number, and defining the processing path corresponding to the abnormal processing device number as an abnormal processing path.

[0126] The similar processing device number refers to the number of the processing device 2 with the same processing type (such as drilling and tapping) as the abnormal processing device, which can replace the abnormal device to complete the same type of processing.

[0127] The abnormal processing path refers to the processing path that should be performed by the abnormal processing device, i.e. the processing path that needs to be replaced by the similar processing device.

[0128] Step S732: determining the sequence based on the abnormal processing device number and the similar processing device number.

[0129] The sequence refers to the time sequence of the similar processing device executing its own processing path and the abnormal processing path, such as the processing path of the abnormal processing device number needs to be completed before the processing path of the similar processing device number in the entire processing flow of the part to be processed.

[0130] Step S733: controlling the machining device 2 corresponding to the similar machining device number to process along the corresponding machining path and the abnormal machining path in the order, and outputting the machining completion signal after the processing is completed, without outputting the abnormal machining device number and the preset abnormal alarm signal.

[0131] The device controls the machining device 2 corresponding to the similar machining device number to process along the corresponding machining path and the abnormal machining path in the order, prevents the damage of the machining part due to the error of the order, and outputs the machining completion signal after the processing is completed, indicating that the next processing can be performed, and because the similar machining device completes the abnormal machining path of the abnormal machining device, the abnormal alarm signal does not need to be outputted.

[0132] Step S734: outputting the abnormal machining device number and the preset abnormal alarm signal when the similar machining device number does not exist.

[0133] When the similar machining device number does not exist, it indicates that there is no machining device 2 in all machining devices 2 that can complete the abnormal machining path of the abnormal machining device, so that the machining part cannot be processed into the sample part pattern, and thus the abnormal alarm signal and the abnormal machining device number need to be outputted to inform the staff.

[0134] The method further comprises controlling the similar machining device number to process along the machining path and the abnormal machining path in the order, and the method comprises.

[0135] Step S7330: defining the machining path corresponding to the similar machining device number as a similar machining path.

[0136] Step S7331: determining an intermediate machining device number based on the similar machining device number and the abnormal machining device number, and defining the machining path corresponding to the intermediate machining device number as an intermediate machining path.

[0137] The intermediate machining device number refers to the number of the machining device 2 located between the workstations corresponding to the similar machining device and the abnormal machining device.

[0138] Step S7332: determining the relevance based on the intermediate machining path, the similar machining path and the abnormal machining path.

[0139] The relevance refers to the process dependency relationship between the intermediate machining path, the similar machining path and the abnormal machining path, such as drilling first, chamfering second and tapping last. The implementation means is a built-in process relevance rule library in the device, which stores the preset process logic (such as drilling, chamfering and tapping in the necessary order), and then judges whether there is relevance among the three by identifying the processes of the intermediate machining path, the similar machining path and the abnormal machining path.

[0140] Step S7333: determining the rotation angle based on the intermediate machining device number and the similar machining device number.

[0141] The rotation angle refers to the angle that the rotating disc 4 rotates from the station corresponding to the intermediate machining device to the station corresponding to the similar machining device. The determination method is that the equipment multiplies the difference between the intermediate machining device number and the similar machining device number by the preset sub-station angle. For example, if the intermediate machining device number is three and the similar machining device number is five, and the preset sub-station angle is 45 degrees, then the rotation angle is 90 degrees.

[0142] Step S7334: if the correlation is the preset necessary sequence, defining the machining path that is processed first between the similar machining path and the abnormal machining path as the first machining path, and the machining path that is processed later as the second machining path.

[0143] The first machining path refers to the path that is processed first between the similar machining path and the abnormal machining path. For example, in the overall machining process, the similar machining path is arranged to be processed before the abnormal machining path, and then the similar machining path is the first machining path. The second machining path refers to the path that is processed later between the similar machining path and the abnormal machining path. For example, in the overall machining process, the similar machining path is arranged to be processed after the abnormal machining path, and then the similar machining path is the second machining path. The implementation means is that the equipment identifies the similar machining device number and the abnormal machining device number corresponding to the similar machining path and the abnormal machining path and compares them. For example, if the similar machining device number is three and the abnormal machining device number is five, then the similar machining path is the first machining path.

[0144] Step S7335: identifying the first completed path of the part to be machined at the station corresponding to the similar machining device number, and the second completed path at the station corresponding to the intermediate machining device number.

[0145] The first completed path refers to the record of the machining path that has been completed by the part to be machined at the station corresponding to the similar machining device. The second completed path refers to the record of the machining path that has been completed by the part to be machined at the station corresponding to the intermediate machining device. The implementation means is that the equipment analyzes the image recognized by the camera installed on the machining device 2 to obtain the record of the machining path.

[0146] Step S7336: if the first completed path does not include the first machining path, controlling the similar machining device to process according to the first machining path.

[0147] If the first completed path does not include the first machining path, it means that the machining of the first machining path is still missing when machining the similar machining path of the workpiece to be machined, and the workpiece to be machined needs to be machined according to the first machining path first. The implementation means is that the device analyzes the image recognized by the camera installed on the machining device 2 to obtain the record of the machined path, and judges whether the first machining path is completed by analyzing the record of the machined path.

[0148] Step S7337: After controlling the similar machining device number to machine according to the first machining path, control the rotating disc 4 to rotate according to the rotation angle.

[0149] After controlling the similar machining device number to machine according to the first machining path, it means that the workpiece to be machined can be machined according to the intermediate machining path, and controlling the rotating disc 4 to rotate according to the rotation angle means rotating the workpiece to be machined to the work station of the intermediate machining device, so that the intermediate machining device can machine the workpiece to be machined according to the intermediate machining path.

[0150] Step S7338: If the first completed path includes the first machining path and the intermediate machining path, control the similar machining device to machine according to the second machining path.

[0151] If the first completed path includes the first machining path and the intermediate machining path, it means that the workpiece to be machined can be machined according to the second machining path. The implementation means is that the device analyzes the image recognized by the camera installed on the machining device 2 to obtain the record of the machined path, and judges whether the first machining path and the intermediate machining path are completed by analyzing the record of the machined path.

[0152] Step S7339: If the first completed path includes the first machining path but does not include the intermediate machining path, control the rotating disc 4 to rotate according to the rotation angle.

[0153] If the first completed path includes the first machining path but does not include the intermediate machining path, it means that when the workpiece to be machined is located at the position of the similar machining device, the second machining path cannot be machined because the intermediate machining path has not been machined. Therefore, the device controls the rotating disc 4 to rotate according to the rotation angle, rotates the workpiece to be machined to the work station of the intermediate machining device corresponding to the intermediate machining path, so that the intermediate machining device can machine the workpiece to be machined according to the intermediate machining path. The implementation means is that the device analyzes the image recognized by the camera installed on the machining device 2 to obtain the record of the machined path, and judges whether the first machining path and the intermediate machining path are completed by analyzing the record of the machined path.

[0154] Step S7340: If the second completed path does not include the first machining path, control the rotating disc 4 to rotate according to the rotation angle.

[0155] If the second completed path does not include the first machining path, it means that the workpiece located in the intermediate machining device cannot be machined according to the second machining path because the workpiece has not completed the first machining path, and needs to be rotated to the similar machining device according to the rotation angle of the equipment control turntable 4, and the similar machining device completes the first machining path. The implementation means is that the equipment analyzes the image recognized by the camera installed on the machining device 2 to obtain the record of the machined path, and judges whether the first machining path is completed by analyzing the record of the machined path.

[0156] Step S7341: If the second completed path includes the first machining path but does not include the intermediate machining path, control the intermediate machining device to machine according to the intermediate machining path.

[0157] If the second completed path includes the first machining path but does not include the intermediate machining path, it means that the workpiece has the precondition for machining according to the intermediate machining path (here, the precondition refers to having completed the first machining path), so the equipment can control the intermediate machining device to machine the workpiece according to the intermediate machining path. The implementation means is that the equipment analyzes the image recognized by the camera installed on the machining device 2 to obtain the record of the machined path, and judges whether the first machining path and the intermediate machining path are completed by analyzing the record of the machined path.

[0158] Step S7342: If the second completed path includes the first machining path and the intermediate machining path, control the turntable 4 to rotate according to the rotation angle.

[0159] If the second completed path includes the first machining path and the intermediate machining path, it means that the workpiece has the precondition for machining according to the second machining path (here, the precondition refers to having completed the first machining path and the intermediate machining path), so the equipment can control the turntable 4 to rotate according to the rotation angle, and rotate the workpiece from the work station of the intermediate machining device to the work station of the similar machining device, so that the similar machining device machines the workpiece according to the second machining path. The implementation means is that the equipment analyzes the image recognized by the camera installed on the machining device 2 to obtain the record of the machined path, and judges whether the first machining path and the intermediate machining path are completed by analyzing the record of the machined path.

[0160] The method also includes controlling the machining device 2 corresponding to the machining device number to machine along the machining path, and outputting a preset machining completion signal after machining is completed. The method includes:

[0161] Step S50: Identify the current completed path of the workpiece on the work station corresponding to the machining device number.

[0162] The current completed path refers to a collection of all completed machining paths of the workpiece to be machined at the current machining device corresponding to the work station. The recognition means analyzes the image recognized by the camera installed on the machining device 2 to obtain the record of the completed machining path and integrates it.

[0163] Step S51: When the current completed path contains the machining path or the current completed path does not exist, output the machining completion signal directly.

[0164] When the current completed path contains the machining path or the current completed path does not exist, it means that the workpiece to be machined has completed the machining path corresponding to the machining device 2 at the current location of the machining device 2, or the workpiece to be machined does not need to be machined at the current location of the machining device 2. The implementation means is that the device analyzes the machined path of the workpiece to be machined by recognizing the image captured by the camera on the machining device 2, and compares it with the machining path preset in the machining device 2.

[0165] Step S52: When the current completed path does not contain the machining path, control the machining device 2 corresponding to the machining device number to perform machining along the machining path.

[0166] When the current completed path does not contain the machining path, it means that the workpiece to be machined has not been machined by the machining device 2 according to the machining path at the current location of the machining device 2. The implementation means is that the device analyzes the machined path of the workpiece to be machined by recognizing the image captured by the camera on the machining device 2, and compares it with the machining path preset in the machining device 2.

[0167] Step S53: Output the preset machining completion signal after machining.

[0168] The method further includes a method for obtaining machining information of a workpiece to be machined, which comprises:

[0169] Step S10: After obtaining the machining information of the workpiece to be machined, analyze the machining information to recognize the text content thereof;

[0170] The implementation means is that the device first receives the machining information input by the staff. If it is structured input (such as filling in the machining information template of fixed fields), the text content in the form is directly extracted. If it is unstructured input (such as uploading a handwritten machining information picture or an OCR scanned copy), an optical character recognition (OCR) tool (for pictures) is first called to convert handwritten or printed text in the picture into editable text.

[0171] Step S11: Judge the text content according to the preset machining information database to obtain the correctness of the machining information;

[0172] The processing information database refers to a structured database pre-stored in the equipment and containing various qualified processing information, and the data content covers part material, processing size range, processing type adaptation rule, precision requirement standard, etc. The correctness refers to a judgment standard for judging whether the input processing information is correct, including two judgments of correct and incorrect. The implementation means is that the equipment identifies and analyzes the processing information through the information in the processing information database to judge whether the words or content of the processing information are correct.

[0173] Step S12: if the correctness is correct, the processing information is input.

[0174] If the correctness is correct, it indicates that the input processing information is accurate and can be input into the equipment as processing information.
