Description

Technical Field

[0001] The invention relates to the technical field of tool processing, and in particular to a high-precision numerical control processing equipment based on processing error compensation. Background Art

[0002] In the field of milling, ordinary toolholders cannot achieve real-time monitoring of the tool by the toolholder. In milling, the status of the tool (such as wear, stress, etc.) has a crucial impact on the processing results. However, traditional ordinary toolholders lack the corresponding monitoring mechanism and cannot obtain this information of the tool in real time. As a result, during the processing, the tool may be damaged due to excessive wear or uneven force, which in turn affects the processing quality and precision of the workpiece.

[0003] During the processing, due to the poor rigidity of the material itself, vibration is very easy to occur. The design and material of ordinary tool holders are often unable to effectively suppress this vibration, resulting in a large vibration amplitude during the processing, which not only aggravates the wear of the tool, but also increases the surface roughness of the processed parts, greatly reducing the accuracy. In severe cases, it is easy to cause tool collision, which will not only damage the tool and workpiece, but may even damage the machine tool spindle, reducing processing efficiency.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0025] like Figures 1 to 11As shown, a high-precision CNC machining equipment based on machining error compensation includes a workbench 11, a mounting plate 21 is provided on the top of the workbench 11, a mounting seat 22 is placed on the top of the mounting plate 21, a machined part body 23 is provided on the top of the mounting seat 22, a support frame 12 is provided on the side wall of the mounting plate 21 on the top of the workbench 11, a machining main control machine 13 is provided on the top of the support frame 12, a hydraulic tool holder 14 is connected to the bottom of the machining main control machine 13, a tool 15 is installed on the bottom of the hydraulic tool holder 14, and a positioning mechanism 30 is provided on the top of the mounting plate 21 that can position and clamp mounting seats 22 of different sizes.

[0026] In this embodiment, the hydraulic tool handle 14 adopts a hydraulic tool installation method to install the tool 15. A tool handle body 4 is provided in the hydraulic tool handle 14. The handle of the tool 15 is arranged in the tool handle body 4. The outer wall of the tool handle body 4 is provided with an expansion wall 3. An oil plug 2 is provided between the tool handle body 4 and the hydraulic tool handle 14. A driving key groove 1 is provided at the end of the hydraulic tool handle 14. A tool withdrawal groove 5 is provided on the outer wall of the hydraulic tool handle 14. A centrifugal power cylinder 6 connected to the tool handle body 4 is provided on the side wall of the hydraulic tool handle 14. A positioning groove 7 is provided on the side wall of the hydraulic tool handle 14 away from the driving key groove 1, and a V-shaped groove 8 is provided in the positioning groove 7.

[0027] The hydraulic tool holder 14 clamps the tool 15 handle by the principle that the centrifugal power cylinder 6 pushes the plunger to reduce the volume of the closed oil chamber, increases the liquid pressure in the chamber sleeve, and makes it expand inward. Because of the hydraulic clamping and liquid buffering, the vibration resistance and vibration reduction are good. The hydraulic oil increases the damping of the tool holder, which plays a good role in improving the vibration resistance of the tool holder. When using the hydraulic tool holder 14, the expansion wall 3 data is established as a variable pitch helix model, and Fourier series is used for derivation. The curve formula is set as:

[0028] fx=A+acos(nwt)+bsin(nwt)

[0029] By sampling points and setting the deformation relationship as a variable pitch spiral line, the model measures five sets of data, t is the angle, f(x) is the coordinate of the center line of the variable pitch spiral groove, and the optimal deformation of each chuck is calculated:

[0030] When t = 0, f(x) = -14.470715;

[0031] When t = 180, f(x) = -9.03443;

[0032] When t = 360, f(x) = -3.10887;

[0033] At t = 540, f(x) = -2.99077;

[0034] At t = 720, f(x) = -9.047915;

[0035] When t = 900, f(x) = -14.95144;

[0036] Substituting the data into the formula, we can deduce:

[0037] a=18.12,b=32.61

[0038] The formula is:

[0039] f(x)=3.5754-18.12*cos(0.000908*t*57.2957)+32.61*s in(0.000908*t*57.2957)

[0040] From this we can see that the optimal deformation is 0.018-0.032mm.

[0041] By taking points of the deformation coefficient of the expansion wall to establish a variable pitch helix model, and through a series of calculations such as Fourier series derivation and assumed functions, multiple integrations, and establishment of function models, the optimal deformation amount of 0.18-0.32mm is finally obtained. This data is helpful to further ensure the accuracy of the hydraulic tool handle during manufacturing and the deformation control during use.

[0042] When the tool holder is displaced, the tool holder end face and the spindle shoulder will not be in full contact, and the stiffness will drop sharply. The radial stiffness at this time is defined as the nominal radial stiffness. According to the mechanical model, the bending moment load when the tool holder end face and the spindle end face are about to separate is calculated:

[0043]

[0044] Compared with the ordinary tool holder using a collet to hold the tool, the hydraulic tool holding system reduces the tool runout to 0.003mm after tool clamping, so that the surface quality and processing accuracy of the final product are far superior to those of the product processed by the ordinary tool holder. The design of the hydraulic tool holder 14 and the tool holder body 4 can effectively suppress the vibration during the processing, which not only reduces the wear of the tool, but also improves the surface roughness and accuracy of the processed parts.

[0045] During the use of the equipment, finite element technology is used to conduct in-depth processing stress analysis of the tool holder. In the initial design stage, the elastic modulus of the parts is set to 207GPa, and the Poisson's ratio is 0.25. When the spindle is installed in place, the short taper handle is set as the fixed end constraint. In the simulated conventional milling scenario, the conventional rotational force is usually within 2.6KN, but the test deliberately increases the rotational force to 10KN, and the axial and radial forces are also set to 8KN. After rigorous testing, all components perfectly meet the technical requirements, which can effectively prove that the equipment can prevent tool damage due to uneven force and improve processing quality and precision.

[0046] In this embodiment, the positioning mechanism 30 includes a groove 37 opened on the top of the workbench 11, and a driving motor 38 is arranged in the groove 37. A driving gear 36 is rotatably arranged on the top of the mounting plate 21. The output end of the driving motor 38 is transmission-connected to the bottom of the driving gear 36. Three rotating blocks 34 are arranged on the top of the mounting plate 21 for circumferential rotation around the driving gear 36. The rotating blocks 34 are equidistantly distributed. A gear ring 35 meshingly connected to the driving gear 36 is arranged on the side wall of the rotating block 34. A connecting rod 32 is fixedly arranged on the side wall of the driving gear 36 away from the gear ring 35. A positioning column 31 is arranged on the top of the connecting rod 32. A placement plate 33 is arranged on the top of the rotating block 34. The mounting seat 22 is arranged on the placement plate 33, and the side wall of the positioning column 31 abuts against the side wall of the mounting seat 22. A fixing mechanism 40 is provided on the top of the positioning column 31 to prevent the mounting seat 22 from jumping. The fixing mechanism 40 includes a fixing block 41 fixedly arranged on the top of the positioning column 31, and a rotating shaft 44 is rotatably provided between the inner walls of the fixing block 41. A gear 43 is fixedly sleeved on the shaft body of the rotating shaft 44. A moving rod 46 is movably provided in the fixing block 41, and a rack 45 meshingly connected to the gear 43 is fixedly provided on the top of the moving rod 46. A pressing block 42 is fixedly sleeved on the side of the shaft body of the rotating shaft 44 away from the gear 43, and the surface of the pressing block 42 abuts against the top of the mounting seat 22.

[0047] The mounting seat 22 with the workpiece body 23 mounted thereon is placed on the placement plate 33 on the top of the mounting plate 21, and the drive motor 38 is started. The output end of the drive motor 38 drives the drive gear 36 to rotate. Since the gear ring 35 on the side wall of the rotating block 34 is meshed and connected with the drive gear 36, the rotation of the drive gear 36 will drive the three rotating blocks 34 to rotate equidistantly around the circumference of the drive gear 36. As the rotating block 34 rotates, the positioning column 31 on the top of the connecting rod 32 will gradually approach and abut against the side wall of the mounting seat 22 to achieve the positioning of the mounting seat 22. When the positioning column 31 is When the movable rod 46 approaches the side wall of the mounting seat 22, the movable rod 46 is pushed to move in the direction away from the mounting seat 22, and the rack 45 on the top of the movable rod 46 is meshed with the gear 43. The movement of the movable rod 46 can drive the gear 43 and the rotating shaft 44 to rotate, thereby driving the pressing block 42 to move downward, and the surface of the pressing block 42 abuts against the top of the mounting seat 22 to fix the mounting seat 22. The design of the positioning mechanism 30 and the fixing mechanism 40 enables the device to flexibly position and fix mounting seats 22 of different sizes, thereby improving the versatility and flexibility of the device and being suitable for various processing requirements.

[0048] In this embodiment, a sensor is provided at the bottom of the hydraulic tool handle 14, and the processing main control computer 13 receives signals through a wireless signal transceiver module. The processing main control computer 13 adopts an intelligent control macro program to dynamically compensate for wear. The intelligent control macro program verifies the accuracy of the wear data fed back by the neural network through a PID algorithm.

[0049] Big data fuzzy PID control consists of three different operation steps, as described below:

[0050] (1) Fuzzification: Convert all precise quantities into fuzzy input quantities. To achieve ideal fuzzification, it is necessary to determine the optimal quantization factor.

[0051] (2) Fuzzy reasoning: Obtain the corresponding fuzzy output through control rules and input fuzzy quantities;

[0052] (3) Defuzzification: Convert fuzzy output into precise output.

[0053] By analyzing and introducing the big data fuzzy PID control principle, the fuzzy rules are used to adjust the online PID controller parameters to fully complete the stability optimization control during milling machining. In fuzzy control, the milling force deviation D and the milling force change rate E during the machining process need to be used as controller input variables, and the three control parameters are set as the output variables of the controller. The specific calculation formula is:

[0054] L P =L PO +ΔL P (k);

[0055] L f =L io +ΔL j (k);

[0056] L d =L Do +ΔL D (k);

[0057] ΔL p (k) = L a,b,c (D, E);

[0058] ΔL j (k) = L a,b,c (D(k), E(k));

[0059] ΔL D (k) = L a,b,c (D(k), E);

[0060] The whole process of converting the input and output variables from natural language into numerical information that can be recognized by the big data fuzzy PID controller is the process of fuzzification. In the fuzzification process, the quantization factor is needed as a bridge to obtain the quantization range of the system input and output variables. The fuzzy reasoning process is the core of the big data fuzzy PID control method and the process of forming the control specification. Among them, the fuzzy quantity E of the output variable is:

[0061]

[0062] S i =(x i and y i )·S i

[0063] The amount obtained by fuzzy reasoning is the fuzzy amount. The fuzzy amount is converted into a clear amount through the centroid algorithm. The detailed calculation formula is:

[0064]

[0065] The sensor at the bottom of the hydraulic tool handle 14 can monitor the status of the tool 15 in real time, such as wear, stress status, etc., and send this information to the processing host 13 through the wireless signal transceiver module. The processing host 13 adopts an intelligent control macro program to dynamically adjust the processing parameters according to the real-time monitored tool status to achieve dynamic compensation for wear. The big data fuzzy PID control method is used to complete the milling machine processing stability control. After the system is disturbed by different factors, the state parameters generated by the milling process will change immediately. The sensor can accurately monitor the change information of all state parameters, accurately control the milling speed change, and ensure the stability of the surface processing. When the sensor detects that the parameter conversion is completed, the big data fuzzy PID control unit is used to give the constraint conditions, and the deviations of different performance indicators are compared at the same time. By inputting the host output correction signal into the corresponding tool length compensation value, tool length wear value, tool radius compensation value and tool radius wear value in the device instruction and calling the macro program, the length compensation and radius compensation of the tool are realized, ensuring that the set conditions and indicators are converted during the milling process, and the stability reaches the best state, realizing the milling machine processing stability control.

[0066] Working process and principle: When the device is in use, the mounting seat 22 with the processed part body 23 is placed on the placement plate 33 at the top of the mounting plate 21, and the drive motor 38 is started. The output end of the drive motor 38 drives the drive gear 36 to rotate. Since the gear ring 35 on the side wall of the rotating block 34 is meshed and connected with the drive gear 36, the rotation of the drive gear 36 will drive the three rotating blocks 34 to rotate equidistantly around the circumference of the drive gear 36. As the rotating block 34 rotates, the top of the connecting rod 32 The positioning column 31 will gradually approach and abut against the side wall of the mounting seat 22 to achieve the positioning of the mounting seat 22. When the positioning column 31 approaches the side wall of the mounting seat 22, the moving rod 46 is pushed to move away from the mounting seat 22. The rack 45 on the top of the moving rod 46 is meshed and connected with the gear 43. The movement of the moving rod 46 can drive the gear 43 and the rotating shaft 44 to rotate, thereby driving the pressing block 42 to move downward. The surface of the pressing block 42 abuts against the top of the mounting seat 22 to achieve the positioning of the mounting seat 22. The design of the fixing, positioning mechanism 30 and the fixing mechanism 40 enables the equipment to flexibly position and fix mounting seats 22 of different sizes, thereby improving the versatility and flexibility of the equipment and being suitable for a variety of processing requirements. The handle of the tool 15 is inserted into the handle body 4 in the hydraulic tool handle 14, and the centrifugal power cylinder 6 is started. The centrifugal force generated by the centrifugal power cylinder 6 pushes the expansion wall 3 to expand outward, thereby tightly clamping the handle of the tool 15 to achieve the installation of the tool 15, which can effectively suppress the vibration during the processing process, not only reducing the wear of the tool, but also improving the surface roughness and precision of the processed parts. The sensor at the bottom of the connector 14 can monitor the status of the tool 15 in real time, such as wear, stress status, etc., and send this information to the processing host computer 13 through the wireless signal transceiver module. Through the sensor at the bottom of the connector and the intelligent control macro program of the processing host computer, real-time monitoring and dynamic compensation of the tool status are realized, which can effectively prevent the tool from being damaged due to excessive wear or uneven stress, and improve the processing quality and precision.
