Description

Technical Field

[0001] This invention relates to the field of workpiece processing technology, and in particular to a deformation support, a vibration control device for shell processing, and a control and processing method. Background Technology

[0002] CNC rapid prototyping technology is a subtractive metal cutting method that uses CAM software and CNC cutting tools to machine a solid blank into the desired finished part. Currently, this technology is widely used in the early stages of product prototyping and small-batch production, significantly reducing the cost and time required for casting mold development and improving the efficiency of early-stage product prototyping. However, when machining housings with deep cavities and thin walls, such as those for new energy vehicle motors, transmissions, and engine oil pans, the extensive material removal causes changes in the internal molecular structure of the blank, leading to shell deformation. Under the influence of cutting forces, the sidewalls of the shell vibrate, generating cutting marks on the surface, severely affecting surface quality and dimensional accuracy.

[0003] Existing Technology 1: For the technical challenge of machining vibration marks in thin-walled motor housings, anti-vibration tool holders and rods are often used to reduce tool vibration during cutting. Problems: The anti-vibration effect is not very significant when machining deep cavities, and the special anti-vibration structure inside the anti-vibration tool holder or rod significantly increases the cost compared to conventional tools. Existing Technology 2: For housings with large draft angles, tapered tool holders can be used to shorten the exposed tool length and reduce tool vibration during cutting. Problems: This method has significant limitations, easily leading to machine tool collisions, resulting in scrapped parts and damage to the machine tool spindle. Precise calculation of the collision range between the tool holder and the housing is required, and the area around the sidewalls of the housing cannot be machined due to collision factors. Existing Technology 3: Both of the above methods address the machining vibration problem in deep cavities of the housing by reducing tool vibration, but do not effectively solve the vibration of the thin-walled housing itself. For vibrations caused by thin-walled shells, auxiliary supports are often used to counteract the vibration. This can be achieved by installing support points at easily vibrating areas of the thin shell, or by filling the cavity with sponge to enhance the shell's strength and reduce its vibration. However, this method has several drawbacks: it cannot effectively monitor part deformation in a timely manner; excessive support can cause significant deformation; and when the support is loosened and tightened, the support rebounds, affecting the machining accuracy of the product. Furthermore, insufficient support cannot effectively solve the vibration problem caused by thin-walled shells. Summary of the Invention

[0004] The purpose of this invention is to provide a deformation support, a vibration control device for shell processing, and a control and processing method.

[0030] If the comparison result shows that the supporting force is less than the pressure setting value, the drive control device controls the motor to turn on, and the motor drives the support rod to extend relative to the support body until the supporting force of the pressure sensing head increases to the pressure setting value, and then the drive control device controls the motor to turn off.

[0031] If the comparison result shows that the supporting force is greater than the pressure setting value, the drive control device controls the motor to start, and the motor drives the support rod to retract relative to the support body until the supporting force of the pressure sensing head is reduced to the pressure setting value, and the drive control device controls the motor to shut down.

[0077] Example 1

[0078] See Figure 1 , Figure 2 As shown in the embodiment of this application, a deformable support device 100 is provided, comprising a support body 1; a drive assembly 3 is disposed inside the support body 1; a support rod 2 has a pressure-sensitive head 4 connected to its first end, and a second end slidably disposed inside the support body 1 and driven to be connected to the drive assembly 3, extending and retracting relative to the support body 1 under the drive of the drive assembly 3; wherein, the pressure-sensitive head 3 is supported on the surface of the workpiece, and the pressure-sensitive head 4 is connected to a pressure sensor 5; a pressure data processing device 6 is electrically connected to the pressure sensor 5, and compares the data collected by the pressure sensor 5 with the pressure set value; a drive control device 7 is electrically connected to the drive assembly 3 and the pressure data processing device 6 respectively; the drive control device 7 controls the drive assembly 3 to drive the support rod 2 to extend and retract according to the data compared by the pressure data processing device 6, so that the supporting force of the pressure-sensitive head 4 on the surface of the workpiece is always the pressure set value.

[0079] In this embodiment, the support body 1 is square, and the second end of the support rod 2 is connected to the center of the square support body 1. A protective sleeve is provided at the end of the support body 1 where it connects to the support rod 2, and the second end of the support rod 2 slides sequentially within the protective sleeve and the support body 1. The protective sleeve prevents the support rod 2 from shifting during extension and retraction when it is relatively long.

[0080] The pressure-sensitive head 4 is always supported on the workpiece surface during workpiece processing. The pressure sensor 5 monitors the supporting force of the pressure-sensitive head 4 on the workpiece surface in real time. When the internal molecular structure of the workpiece deforms during processing, the supporting force between the pressure-sensitive head 4 and the workpiece surface changes. The pressure sensor 5 transmits the monitored supporting force data to the pressure data processing device 6. The pressure data processing device 6 compares the received supporting force data with the pressure set value and transmits the comparison result to the drive control device 7. The drive control device 7 controls the extension or retraction of the support rod 2 according to the received comparison result. Specifically, if the comparison result shows that the supporting force is less than the pressure set value, it indicates that the workpiece is deformed away from the support rod 2. Then, the drive control device 7 controls the drive assembly 3 to drive the support rod 2 to slide towards the workpiece, that is, to extend relative to the support body 1, until the supporting force of the pressure-sensitive head 4 increases to the pressure set value. If the comparison result shows that the supporting force is greater than the pressure set value, it indicates that the workpiece is deformed towards the support rod 2. Then, the drive control device 7 controls the drive assembly 3 to drive the support rod 2 to slide away from the workpiece, that is, to retract relative to the support body 1, until the supporting force of the pressure-sensitive head 4 decreases to the pressure set value.

[0081] The above solution allows for timely and effective monitoring of part deformation, ensuring that support rod 2 maintains a constant supporting force on the workpiece during processing. Firstly, it avoids excessive support that could cause significant workpiece deformation, leading to surface rebound when the support is released, which would affect product machining accuracy. Secondly, it avoids the problem of insufficient support failing to effectively address vibration issues during the machining of the shell workpiece.

[0082] Furthermore, the second end of the support rod 2 is connected to the drive assembly 3 via a lead screw 8; the lead screw 8 is rotatably connected to the drive assembly 3, and the lead screw 8 is provided with an external thread, while the inner wall of the second end of the support rod 2 is provided with an internal thread that rotates in conjunction with the external thread.

[0083] The drive assembly 3 drives the lead screw 8 to rotate. When the lead screw 8 rotates, it drives the support rod 2 to slide through the rotating thread, so as to realize the function of the support rod 2 extending or retracting relative to the support body 1.

[0084] In another alternative scheme, the pressure sensor 5 is located inside the support rod 2, and the pressure data processing device 6 and the drive control device 7 are both located inside the support body 1; the second end of the support rod 2 is connected to the drive assembly 3 through the lead screw 8; the lead screw 8 is rotatably connected to the drive assembly 3, and the lead screw 8 is provided with an external thread; the second end of the support rod 2 is internally connected to the support rod lead screw 9 through an interference fit, and the support rod lead screw 9 is provided with an internal thread that is optionally matched with the external thread.

[0085] Specifically, the pressure data processing device 6 and the drive control device 7 are symmetrically arranged at both ends of the lead screw 8. The advantage of this design is that by placing the pressure sensor 5, pressure data processing device 6, and drive control device 7 inside the support body 1, it prevents their external placement from interfering with the construction of the support cluster. Since the pressure sensor 5, pressure data processing device 6, and drive control device 7 are all located inside the support body 1, their connecting lines are also arranged inside the support body 1. To prevent the connecting lines from affecting the transmission between the support rod 2 and the lead screw 8, a bushing is provided at the second end of the support rod 2. The connecting lines are first arranged on the inner wall of the bushing, and then the support rod lead screw 9 is connected inside the bushing via an interference fit. The support rod lead screw 9, in cooperation with the lead screw 8, rotates to achieve the function of extending or retracting the support rod 2 relative to the support body 1.

[0086] Furthermore, the drive component 3 is a motor, and the drive control device 7 has a built-in motor data processing module used to calculate the extension distance of the support rod 2 based on the motor rotation angle. The extension distance S of the support rod 2 is calculated according to the following formula: S = α·k; where α is the motor rotation angle and k is the lead screw transmission coefficient.

[0087] Example 2

[0088] See Figure 3 , Figure 4 As shown in the embodiment of this application, a shell processing vibration control device includes a support cluster built by the aforementioned deformation support device 100 and a data processing terminal; the first end of the support rod 2 of the support cluster is evenly supported on the side wall and bottom surface of the shell 13 to be processed; the drive control device 7 of the support cluster is wirelessly connected to the data processing terminal, and the data processing terminal analyzes the deformation of the shell 13 according to the extension distance of the support rod 2.

[0089] This embodiment is a vibration control device for thin-walled shell processing. A shell support cluster is built so that monitoring points are evenly distributed on the shell surface. The pressure sensor 5 at each monitoring point monitors the support force of the pressure sensing head 4 on a certain part of the shell in real time. When the shell deforms during processing, the support force between the pressure sensing head 4 and the shell surface changes. The pressure sensor 5 transmits the monitored support force data to the pressure data processing device 6. The pressure data processing device 6 compares the received support force data with the pressure set value and transmits the comparison result to the drive control device 7. The drive control device 7 controls the motor to drive the support rod 2 to extend or retract according to the received comparison result.

[0090] The above solutions allow for timely and effective monitoring of part deformation, ensuring uniform pressure at each support point on the housing. Firstly, excessive support prevents significant housing deformation, which can cause workpiece surface rebound when the support is released, affecting machining accuracy. Secondly, the evenly distributed deformation support significantly strengthens the thin-walled housing, preventing vibration during cutting and effectively improving surface quality.

[0091] During the processing, the data processing terminal generates a mesh model of the shell deformation based on the extension and retraction distance of the support rods in the support cluster. At the same time, the simulated shell support cluster model is imported into the data processing terminal. The data processing terminal compares and analyzes the data of the two models, and outputs a shell deformation report and analysis results in real time. It can grasp the deformation information of the thin-walled shell in real time during the processing, accurately control the finishing allowance, adjust the cutting parameters of the tool and the disassembly and assembly parameters, avoid irregular precision deviations caused by uneven finishing allowance, and avoid springback deformation caused by the release of clamping force after the thin-walled motor shell is disassembled.

[0092] Furthermore, a support cluster is constructed. When the support bodies 1 need to be connected, the support bodies 1 are connected by connecting rods 12. The square support bodies 1 have shaft holes 1-1 in different directions.

[0093] When the support cluster is square, and the two connected support bodies 1 are in the same direction, the two ends of the connecting rod 12 are respectively connected to the shaft holes 1-1 on the two adjacent support bodies 1; when the two connected support bodies 1 are in different directions, the connecting rod 12 between the support bodies 1 is connected by the connecting block 11, and the two ends of the connecting rod are respectively connected to the shaft holes 1-1 on the support body 1 and the shaft holes opened in the connecting block 11.

[0094] When the support cluster is circular, two adjacent left and right connecting rods 12 are connected by connecting rings 14; the two ends of the connecting rings 14 pass through the two adjacent connecting rods 12 respectively and are then fastened by bolts 15.

[0095] Example 3

[0096] This embodiment provides a control method for a housing processing vibration control device, including the following steps:

[0097] S101, Pressure sensor 5 collects the supporting force of pressure head 4 in real time;

[0098] S102, Pressure data processing device 6 compares the support force with the pressure set value;

[0099] S103, the drive control device 7 controls the motor to drive the support rod 2 to extend or retract relative to the support body 1 according to the comparison results, so that the support cluster is constantly supported on the shell; the specific method is as follows:

[0100] If the comparison result shows that the supporting force is less than the pressure setting value, the drive control device 7 controls the motor to turn on, and the motor drives the support rod 2 to extend relative to the support body 1 until the supporting force of the pressure sensing head 4 increases to the pressure setting value, and the drive control device 7 controls the motor to turn off.

[0101] If the comparison result shows that the supporting force is greater than the pressure setting value, the drive control device 7 controls the motor to start, and the motor drives the support rod 2 to retract relative to the support body 1 until the supporting force of the pressure sensor head 4 is reduced to the pressure setting value, and the drive control device 7 controls the motor to shut down.

[0102] Example 4

[0103] Reference Figures 3-5 As shown, this embodiment provides a method for processing a thin-walled motor housing, including the following steps:

[0104] First, select a positioning and fixing scheme based on the thin-walled motor housing structure, and calculate the space and position occupied by the press-fitting components;

[0105] Specifically, analyzing the motor housing structure, the upper and lower end faces are flat, with evenly distributed threaded holes and two pin holes, which can be used for positioning and fixing the motor housing. First, the flat surface, threaded holes, and pin holes on one side of the bearing hole in the motor housing are rough-machined for subsequent finishing and fixing. The rough machining positioning selection is as follows... Figure 3 Using the top surface in the indicated direction as a reference, invert the motor housing onto the worktable base plate. Use bolts and clamps to fix the motor housing to the worktable base plate, and select a plane on the motor housing for horizontal alignment. The machining dimensions of the threaded holes and pin holes are smaller than the dimensions required by the drawing (e.g., machining an M10 thread into an M8 thread, machining a φ10h7 pin hole into a φ8H7 pin hole), which will not affect the positional accuracy and dimensional accuracy of the holes during finishing.

[0106] The first-stage precision machining scheme is formulated as follows: A "one-sided, two-pin" positioning method is selected. The rough-machined bearing hole on one side is used as a positioning reference, the two rough-machined pin holes are used for position positioning, and the rough-machined threaded holes are used for fixing the motor housing. Bolts are used to press the motor housing into place. Figure 3The direction shown is fixed on the base plate.

[0107] S201. Based on the structure of the thin-walled motor housing and the location occupied by the press-fit components, simulate and build the external and internal support cluster model of the motor housing in the software, and import the simulated external and internal support cluster model of the housing into the data processing terminal.

[0108] Specifically, the 3D model of the motor housing is imported into the software built into the data processing terminal, and the spatial position of the 3D model of the motor housing in the system coordinate system is adjusted according to a sequential precision machining positioning scheme. Based on the structure of the motor housing and the location of the bottom fixing bolts, the support point positions on the side wall of the motor housing are selected so that the support points are evenly distributed on the surface of the motor housing. Based on the remaining space of the base plate and the maximum occupancy range of the motor housing, the boundary of the support cluster is calculated, and support rods and connecting rods of suitable length are selected. The external and internal support cluster models of the thin-walled motor housing are then built in the software.

[0109] S202. Locate the external support cluster using the simulated external support cluster model and build a support cluster outside the shell 13 to be processed; connect the drive control device 7 of the external support cluster to the data processing terminal.

[0110] Specifically, based on the simulated model of the motor housing's external bottom support cluster built in the software, the support position of the motor housing bottom deformation support device 100 is located on the base plate, and positioning holes and threaded holes are machined on the base plate. The connecting rod is connected to the base plate through threads, and the deformation support device is connected to the connecting rod to complete the construction of the motor housing bottom support cluster.

[0111] Based on the simulated spatial position of the motor housing in the software, two locating pin holes and pull bolt holes are machined on the base plate. The bearing hole side of the motor housing is fixed to the base plate with bolts using a "one-sided two-pin" positioning method.

[0112] Based on the simulated model of the motor housing external sidewall support cluster built in the software, the support positions of the motor housing external sidewall deformation support device 100 are located on the external sidewall and the base plate. Positioning holes and threaded holes are machined on the base plate, and the connecting rod is connected to the base plate through threads. The deformation support device is connected to the connecting rod, and the motor housing external sidewall support cluster is built layer by layer from bottom to top.

[0113] Turn on all deformable support devices 100, and the data processing terminal searches for the wireless transmission signals of each deformable support device 100 to complete the data transmission channel connection. After confirming that each deformable support device 100 is working properly, adjust the extension length of the support rod, set the initial pressure, and reset the deformation data of the motor housing to zero.

[0114] S203: Rough machining of elements such as the inner cavity plane, side walls, threaded holes, and bearing holes of the thin-walled motor housing; real-time output of housing deformation report and analysis results from the data processing terminal; adjustment of finishing allowance based on housing deformation report and analysis results;

[0115] For example, if the deformation is 0.5mm during rough machining of a certain part of the shell, and the finishing allowance is 0.2mm based on the undeformed condition, the surface will not be machined. Based on the deformation analysis, a reasonable finishing allowance should be reserved.

[0116] S204: Precision machining of elements such as the inner cavity plane, sidewalls, threaded holes, and bearing holes of thin-walled motor housing; real-time output of housing deformation reports and analysis results from the data processing terminal; adjustment of tool cutting parameters based on housing deformation reports and analysis results;

[0117] For example, areas on the shell with minimal deformation indicate better strength, allowing for a faster cutting speed. Conversely, areas with significant deformation require a slower cutting speed. This balances machining accuracy and efficiency.

[0118] S205. Locate the internal support cluster using a simulated internal support cluster model and build a support cluster inside the shell 13 to be processed; connect the drive control device 7 of the internal support cluster to the data processing terminal.

[0119] Specifically, based on the simulated internal support cluster model of the motor housing built in the software, the internal support cluster of the motor housing is built layer by layer from bottom to top. The support rods of the bottom deformable support device 100 rest on the bottom surface of the inner cavity of the motor housing without being fixed, serving as auxiliary support. Since the internal support cluster of the motor housing is a circular structure, connecting rings and clamping nuts are used to connect and fix the deformable support device 100. The support rods are fixed to the deformable support device 100, and the connecting ring passes through two adjacent support rods and is then connected to the deformable support device 100 using clamping nuts.

[0120] Turn on all deformable support devices 100, and the data processing terminal searches for the wireless transmission signals of each deformable support device 100 to complete the data transmission channel connection. After confirming that the deformable support device 100 is working properly, adjust the extension length of the support rod, set the initial pressure, and reset the deformation data of the motor housing to zero.

[0121] S206. Disassemble the external support cluster of the thin-walled motor housing; the data processing terminal outputs a housing deformation report and analysis results in real time; adjust the disassembly parameters based on the housing deformation report and analysis results;

[0122] To prevent the thin-walled motor housing from springing and deforming due to the release of clamping force after the support cluster is disassembled, the disassembly location and disassembly time are precisely controlled based on deformation analysis.

[0123] S207. Rough machining of elements such as the external plane, sidewalls, threaded holes, and bearing holes of the thin-walled motor housing; the data processing terminal outputs a housing deformation report and analysis results in real time; based on the housing deformation report and analysis results, the finishing allowance is controlled by region.

[0124] S208: Precision machining of elements such as the external plane, sidewalls, threaded holes, and bearing holes of the thin-walled motor housing; the data processing terminal outputs a housing deformation report and analysis results in real time; the tool cutting parameters are adjusted based on the housing deformation report and analysis results.

[0125] S209. Finish machining of the positioning surface used in the previous machining process; the data processing terminal outputs the shell deformation report and analysis results in real time; adjust the tool cutting parameters according to the shell deformation report and analysis results;

[0126] After finishing, the fixing bolts of the thin-walled motor housing are removed. Based on the simulated external support cluster model of the motor housing built in the software, the following is machined on the base plate: Figure 3 The top surface threaded hole and locating pin hole, as shown in the placement direction, are used to fix the motor housing to the base plate with bolts using a "one-sided, two-pin" positioning method. The bearing hole side surface, threaded hole, and pin hole are then precision machined. Real-time monitoring and analysis of the thin-walled motor housing deformation are conducted to adjust the tool cutting parameters.

[0127] S210. Disassemble the internal support cluster of the thin-walled motor housing; the data processing terminal outputs a housing deformation report and analysis results in real time; adjust the disassembly parameters based on the housing deformation report and analysis results.

[0128] S211. Disassemble the thin-walled motor housing to complete the machining.

[0129] In the above processing method, the data processing terminal outputs a real-time report and analysis results on the deformation of the thin-walled motor housing, allowing for real-time monitoring of the deformation information during processing. This enables precise control of the finishing allowance, tool cutting parameters, and assembly / disassembly time, avoiding irregular precision deviations caused by uneven finishing allowances and springback deformation caused by the release of clamping force after disassembly. This effectively improves the manufacturing quality of the thin-walled motor housing, achieving lightweight design while meeting structural requirements.
