TECHNICAL FIELD
[0001] The present application relates to the technical field of aero-engine, and particularly relates to a precision quick correction method for linear welding blisk five-axis machining equipment. BACKGROUND
[0002] The blisk has strict requirements on the machining precision of the five-axis machining equipment, and the linear welding blisk five-axis machining equipment has a slant bed structure and is very sensitive to temperature. However, due to seasonal temperature difference, the equipment precision may be abnormal, and when the abnormality occurs, the original point data of the five-axis equipment needs to be recalibrated.
[0003] The traditional five-axis machining equipment needs to be disassembled, the measuring head needs to be calibrated, and then the equipment needs to be run for 6-8 hours to calibrate the original point data, which has the risk of human operation and judgment error and is low in efficiency. In addition, due to the disassembly of the parts, the quality risk of the parts is caused, and the data recording function is not provided, so that the big data analysis cannot be formed, the seasonal change rule of the equipment cannot be counted, the efficient application of the equipment is not conducive, and the traditional method does not have the data recovery function. SUMMARY
[0004] The present application aims at solving the above-mentioned problems of the prior art, and provides a precision quick correction method for linear welding blisk five-axis machining equipment, which realizes the quick correction of the precision of the blisk five-axis machining equipment.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present application is as follows: a precision quick correction method for linear welding blisk five-axis machining equipment, comprising the following steps:
[0006] Step 1: calibrate the laser tool setting instrument data, when the blisk five-axis machining equipment reaches the thermal equilibrium state, perform the tool setting instrument calibration action, after calibration, use the tool setting program to measure the length and radius size of the standard tool, and determine whether the difference between the measured length and radius of the standard tool and the theoretical length and radius is within the set range, if not, continue to perform the tool setting instrument calibration work, and then use the tool setting program to measure the length and radius size of the standard tool, until the difference between the length and radius size of the standard tool is within the set range, that is, the tool setting instrument calibration step is ended, and then step 2 is executed; after the tool setting instrument calibration is completed, the tool setting instrument calibration action is not performed in the subsequent machining; the tool setting program adopts a single-side measurement program;
[0007] Step 2: In the normal processing of the linear welding blisk five-axis machining equipment, the perpendicularity of the equipment is fed back by measuring the length and radius change of the standard tool; the standard tool is measured by the tool program, if the measured length and radius and the standard tool theoretical length and radius differ by more than 0.01 mm, it is determined that the perpendicularity of the linear welding blisk machining equipment deviates, when the equipment perpendicularity exceeds the set difference, the measured values of the standard tool in the length direction and the radius direction are measured, and the measured values of the standard tool equipment are compared with the standard tool theoretical values, the Z-axis and Y-axis overage values of the standard tool are calculated;
[0008] Z-axis overage value = standard tool theoretical length value - standard tool measured length value;
[0009] Y-axis overage value = standard tool theoretical radius value - standard tool measured radius value;
[0010] Step 3: According to the Z-axis and Y-axis overage values of the standard tool, the origin of the blisk five-axis machining equipment is updated by the Siemens system instruction;
[0011] Before the origin is updated, the Z-axis and Y-axis overage values are recorded as the original coordinate system value of the blisk five-axis machining equipment in the equipment GUD parameter for calling, the instruction is as follows
[0012] Y_ZERO_YUANSHI = $MA_REFP_MOVE_DIST_CORR[1, AX2]
[0013] Z_ZERO_YUNASHI = $MA_REFP_MOVE_DIST_CORR[1, AX3]
[0014] Wherein, X3 is the Z-axis coordinate of the standard tool, AX2 is the Y-axis coordinate of the standard tool;
[0015] The Siemens instruction used for the origin update correction of the blisk five-axis machining equipment is as follows:
[0016] $MA_REFP_MOVE_DIST_CORR[1, AX3] = $MA_REFP_MOVE_DIST_CORR[1, AX3] - Z-axis overage value
[0017] $MA_REFP_MOVE_DIST_CORR[1, AX2] = $MA_REFP_MOVE_DIST_CORR[1, AX2] + Y-axis overage value
[0018] Step 4: After the origin of the overall blisk five-axis machining equipment is updated, the equipment is shut down and then restarted, the modified equipment origin data is activated, after the data is activated, the actual measured values of the standard tool in the length direction and the radial direction are measured again by using the tool measurement program, and the actual measured values of the standard tool in the length direction and the radial direction are compared with the theoretical values, if the deviations of the length and the radius of the standard tool are both less than the set value, the equipment precision calibration work is completed, otherwise step 2 is executed again until the deviations of the length and the radius of the standard tool are both less than the set value.
[0019] The beneficial effects generated by the above technical scheme are that the linear welding overall blisk five-axis machining equipment precision rapid correction method provided by the application can automatically calibrate through a program, ensure that the equipment precision meets the technical requirements, and has a significant effect compared with the traditional calibration method, the original calibration time of about 8 hours is shortened to within 3 minutes, the calibration time is shortened by 99.375%, the equipment precision rapid correction time is improved by one order of magnitude, and the quality risk caused by the disassembly and calibration of the parts is avoided. The economic benefit is directly proportional to the value of the parts. In the past six years, the equipment depreciation, equipment capacity and other comprehensive costs have been saved, and the statistical amount is about 3 million yuan. Alarm prompt information is prepared to prompt the operator whether to perform the origin parameter refreshing action.
[0020] Moreover, there is a record data function, forming big data analysis, and the seasonal variation law of the equipment is counted, which is beneficial to the efficient application of the equipment, and the original method is supplemented to avoid the disadvantage of data recovery.

[0024] The specific embodiments of the application will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the application, but not to limit the scope of the application.
[0025] The linear welding overall blisk machining equipment is as follows Figure 1As shown, due to its slant bed structure, it is very sensitive to temperature. Experiments have shown that temperature changes can cause changes in the verticality of the equipment. Immediately after the work is completed, the verticality was measured to be 0.01mm using a marble right-angle ruler. After 15 hours of storage, the verticality changed to 0.068mm. Therefore, the change in verticality caused by temperature changes has affected the machining accuracy of the parts.
[0026] Depend on Figure 1 It is known that during the processing, the heat generated is carried away by the exhaust fan 8. Due to atmospheric pressure, a negative pressure is generated at the bottom of the equipment to the processing area, supplementing the external air 3. Cooled cutting fluid flows on the surface of the coolant flow. Fluctuations in room temperature cause fluctuations in the external air 3. Due to the bimetallic deformation effect of metals, the perpendicularity 9 of the equipment will exceed the tolerance. The change in perpendicularity 9 will cause the distance from the standard tool 5 to the origin 4 of the tool setter to change. The measured length and radius of the standard tool will both exceed the preset tolerance. Since the tool setter and the component where the equipment origin 10 is located are rigidly connected, the change in the equipment origin can be calculated based on the changes in the measured values of the standard tool length and radius.
[0027] If the deviation is too large—the criterion for excessive deviation is that the standard tool length and radius exceed the theoretical data by 0.015 mm, and adjusting the cutting fluid temperature cannot restore the standard tool data to a qualified state—then the program needs to reset the equipment origin. Therefore, to compensate for errors caused by changes in equipment perpendicularity, the compensation can ultimately be achieved by changing the equipment origin data.
[0028] In this embodiment, a method for rapid accuracy correction of a five-axis machining equipment for linearly welded integral bladed disks is described, such as... Figure 2 As shown, it includes the following steps:
[0029] Step 1: Calibrate the laser tool setter data. When the five-axis machining center for the integral impeller disk reaches thermal equilibrium, perform the tool setter calibration. After calibration, use the tool setting program to measure the length and radius of the standard tool. Determine if the difference between the measured length and radius of the standard tool and the theoretical length and radius is within the set range (0.005mm). If it is not within the set range (0.005mm), continue the tool setter calibration process. Then use the tool setting program to measure the length and radius of the standard tool again until the difference between the length and radius of the standard tool is within the set range (0.005mm). At this point, the tool setter calibration step is complete, and then proceed to Step 2. After the tool setter calibration is completed, the tool setter calibration action will not be performed again in subsequent machining.
[0030] When setting the tool radius, the tool setting program can set the tool radius unilaterally or bilaterally. Unilateral setting will accumulate the equipment deformation error into the tool radius, while bilateral setting can eliminate the accumulation of equipment deformation error. Therefore, in order to accumulate the equipment deformation error into the tool radius, this invention uses a unilateral measurement program to measure the standard tool length and radius.
[0031] Step 2: During normal machining of the linear welded integral bladed disk five-axis machining equipment, the verticality of the equipment is fed back by measuring the change in the length of the standard tool; the length and radius of the standard tool are measured through the tool setting program. If the measured length and radius differ from the theoretical length and radius of the standard tool by more than the set range (more than 0.01mm), it is determined that the verticality of the linear welded integral bladed disk machining equipment has deviated. When the verticality of the equipment exceeds the set difference, the measured values of the standard tool in the length and radius directions are measured, and the obtained measured values of the standard tool are compared with the theoretical values of the standard tool to calculate the Z-axis out-of-tolerance value (length) and Y-axis out-of-tolerance value (radius) of the standard tool.
[0032] Z-axis (length) out-of-tolerance value = theoretical length value of standard tool - actual length value of standard tool;
[0033] Y-axis (radius) deviation value = theoretical radius value of standard tool - actual radius value of standard tool;
[0034] Step 3: Update the origin of the five-axis machining equipment for the overall impeller disk according to the Z-axis and Y-axis out-of-tolerance values of the standard tool using Siemens system commands;
[0035] Before updating the origin, record the Z-axis and Y-axis out-of-tolerance values as the original coordinate coefficient values of the overall impeller five-axis machining equipment in the equipment's GUD parameters for later retrieval. The command is as follows:
[0036] Y_ZERO_YUANSHI=$MA_REFP_MOVE_DIST_CORR[1,AX2]
[0037] Z_ZERO_YUNASHI=$MA_REFP_MOVE_DIST_CORR[1,AX3]
[0038] Where X3 is the Z-axis coordinate of the standard tool and AX2 is the Y-axis coordinate of the standard tool;
[0039] The Siemens commands used for origin point update and correction of the integral impeller five-axis machining equipment are as follows:
[0040] $MA_REFP_MOVE_DIST_CORR[1,AX3] = $MA_REFP_MOVE_DIST_CORR[1,AX3] - Z-axis out-of-tolerance value
[0041] $MA_REFP_MOVE_DIST_CORR[1,AX2]=$MA_REFP_MOVE_DIST_CORR[1,AX2]+Y-axis out-of-tolerance value
[0042] Step 4: After updating the origin of the five-axis machining equipment for the integral impeller, shut down the machine and then restart it. Activate the modified origin data. After activation, use the tool measurement program to remeasure the actual values of the standard tool in the length and radius directions. Compare these values with the theoretical values in the length and radius directions of the standard tool. If the deviations of the standard tool length and radius are both less than the set values (0.01mm), the equipment accuracy calibration is complete. Otherwise, repeat Step 2 until the deviations of the standard tool length and radius are both less than the set values.
[0043] In this embodiment, firstly, a tool edge number array D2 for the standard tool is added to the tool parameters. The values in D2 represent the theoretical length and radius of the standard tool, facilitating manual comparison by the operator. Then, a standard tool setting program is developed: The measured tool length and radius values are recorded in the tool edge number array D1, and the data in D1 and D2 are compared to determine the deviation between the measured and theoretical values. The deviation is then displayed on the CNC system screen of the five-axis machining center for the integral impeller, for example, as (tool length difference: 0.044mm, tool radius difference: 0.024mm). This allows the operator to easily identify the deviation and determine whether to perform rapid accuracy correction based on different machining conditions. For the integral impeller, the roughing deviation can be increased to 0.05mm, the blade finishing deviation to 0.03mm, and the blade tip finishing deviation needs to be controlled within 0.01mm to ensure qualified part delivery.
[0044] This display indicates an infinite loop. If the operator does not press the reset button, a prompt will be displayed on the display line to prevent accidental operation and potential deviation issues.

Claims
1. A method for rapid accuracy correction in a five-axis machining equipment for linearly welded integral bladed disks, characterized in that: Includes the following steps: Step 1: Calibrate the tool setter; The laser tool setter data is calibrated when the five-axis machining center for the integral impeller disk reaches thermal equilibrium. After calibration, the tool setter program is used to measure the length and radius of the standard tool. The difference between the measured length and radius and the theoretical length and radius of the standard tool is determined to be within the set range. If not, the tool setter calibration continues, and the tool setter program is used again to measure the length and radius of the standard tool until the difference is within the set range. The tool setter calibration step is then complete, and step 2 is executed. After the tool setter calibration is complete, it is not performed again in subsequent machining. Step 2: When the equipment perpendicularity exceeds the set difference, the Z-axis and Y-axis deviation values of the standard tool are calculated. During normal machining of a five-axis machining center for linear welded integral bladed disks, the perpendicularity of the equipment is fed back by measuring the changes in the length and radius of the standard tool. The standard tool is measured through a tool setting program. If the measured length and radius differ from the theoretical length and radius of the standard tool by more than 0.01 mm, it is determined that there is a deviation in the perpendicularity of the linear welded integral bladed disk machining center. When the perpendicularity of the equipment exceeds the set difference value, the actual measured values of the standard tool in the length and radius directions are measured, and the obtained actual measured values of the standard tool on the machine tool are compared with the theoretical values of the standard tool to calculate the Z-axis and Y-axis out-of-tolerance values of the standard tool. The Z-axis and Y-axis out-of-tolerance values for the standard cutting tool are as follows: Z-axis out-of-tolerance value = theoretical length of standard tool - actual length of standard tool; Y-axis out-of-tolerance value = theoretical radius value of standard tool - actual radius value of standard tool; Step 3: Update the origin of the five-axis machining equipment for the overall impeller disk according to the Z-axis and Y-axis out-of-tolerance values of the standard tool using Siemens system commands; Step 4: Power off and restart the five-axis machining equipment for the integral impeller.
