Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to an intelligent adjustment device for a power source used in forming positioning holes in the front subframe crossbeam. Background Technology

[0002] The forming technology of the front subframe crossbeam positioning holes originates from the modular development and high-precision assembly requirements of automotive chassis. Its application runs through the entire process of design, manufacturing, assembly and performance optimization. It is a key technology to ensure vehicle safety, durability and lightweighting. With the popularization of automotive platform production, the subframe, as the core component of the chassis module, needs to be precisely connected with the body, suspension, steering system and other components. The forming of the front subframe crossbeam positioning holes plays a vital role in automobile manufacturing. Its core significance lies in ensuring the assembly accuracy, structural stability and vehicle performance of the chassis system.

[0003] However, most power sources currently used for positioning hole forming have fixed parameter settings, which cannot be flexibly adjusted according to different materials and specifications of the front subframe crossbeams. In actual production, if the power source parameters are not suitable, it may lead to poor positioning hole forming quality, such as hole diameter deviation and rough hole walls. This not only affects product quality but also increases production costs and production cycle.

[0004] For example, when a manufacturer produces three types of front subframe crossbeams at the same time, using a hydraulic punching machine with fixed parameters, a pressure set to 50 tons, and a constant punching speed (0.5m / s) cannot be adjusted according to the material characteristics, which seriously affects the punching quality. Utility Model Content

[0005] This utility model discloses an intelligent adjustment device for a power source used in forming positioning holes of a front subframe crossbeam, aiming to solve the technical problem that the power source parameters are fixed and cannot be flexibly adjusted according to different materials and specifications of the front subframe crossbeam.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An intelligent adjustment device for a power source used in forming positioning holes in a front subframe crossbeam includes a base, a worktable, and a guide frame. It further includes: an intelligent adjustment mechanism: the intelligent adjustment mechanism includes a connecting frame connected between two of the guide frames, a hydraulic pump mounted on the connecting frame, a telescopic plate mounted at the bottom of the hydraulic pump, a pneumatic cylinder mounted on the top outer wall of the piston end of the telescopic plate, a connecting block mounted on the bottom outer wall of the piston end of the telescopic plate, a fixing frame mounted on the connecting block, a displacement sensor mounted on the fixing frame, a microprocessor mounted on the top outer wall of the fixing frame, and a punch mounted at the connection point between the connecting block and the fixing frame; and an adaptive shape-changing mechanism: the adaptive shape-changing mechanism is mounted on the guide frame.

[0007] In this solution, the intelligent adjustment mechanism and the adaptive shape-changing mechanism work together to ensure the forming accuracy of the positioning holes of the front subframe crossbeam while possessing strong adaptability and flexibility. This effectively improves production efficiency and product quality. During the processing, the intelligent adjustment device quickly processes and issues instructions based on real-time feedback data to precisely control the movement of the punch, thereby ensuring the forming accuracy of the positioning holes of the front subframe crossbeam and reducing processing errors caused by unstable power or displacement deviation.

[0008] In a preferred embodiment, the microprocessor is a high-performance industrial-grade microprocessor, which works in conjunction with the hydraulic pump, the pneumatic cylinder, and the punch.

[0009] This design enables rapid processing of various data and instructions, allowing for on-demand adjustment of the power source parameters required for forming positioning holes in front subframe crossbeams of different materials and specifications. A hydraulic pump provides hydraulic power with an output pressure range of -MPa, while a pneumatic cylinder provides pneumatic power with a working air pressure range of .-.MPa. Power is transmitted to the punch through a connecting block, meeting diverse processing requirements and effectively avoiding positioning hole forming quality problems caused by insufficient or excessive power.

[0010] In a preferred embodiment, the adaptive changing mechanism includes a rail groove disposed on one side of the guide frame. The rail groove is used in conjunction with the connecting frame and forms an X / Y / Z three-axis linkage with the telescopic plate and the connecting frame.

[0011] Through its X / Y / Z three-axis linkage structure design, the device can freely adjust the position and trajectory of the punch in three dimensions. This allows for flexible adaptation to machining tasks requiring positioning holes in front subframe crossbeams of varying shapes, sizes, and positions. Whether the hole is a simple, regular shape or a complex, irregular shape, the three-axis linkage system precisely adjusts the punch's machining path to meet diverse production needs. When it's necessary to change to machining front subframe crossbeams of different specifications, the three-axis linkage system can quickly and accurately adjust the punch's position and related parameters. The cooperation between the rail groove and the connecting frame allows the connecting frame to move flexibly on the guide frame. Combined with the telescopic function of the telescopic plate, no adjustments to the mounting are required. The device allows for large-scale disassembly and reassembly, significantly shortening changeover time, improving production efficiency, and reducing production downtime costs caused by changeovers. Simultaneously, the three-axis linkage system boasts high motion precision and control stability, enabling precise control of the punch's movement distance and speed in the X, Y, and Z directions during processing. This ensures accurate relative positioning of the punch to the front subframe crossbeam, guaranteeing the machining accuracy of the positioning holes, reducing scrap and defects caused by positional deviations, improving product quality, enhancing the device's versatility and applicability, reducing the cost for companies to equip different products with dedicated equipment, and increasing equipment utilization and return on investment.

[0012] As can be seen from the above, an intelligent adjustment device for a power source for forming positioning holes in a front subframe crossbeam includes a base, a worktable, and a guide frame, and further includes: an intelligent adjustment mechanism: the intelligent adjustment mechanism includes a connecting frame connected between two of the guide frames, a hydraulic pump is provided on the connecting frame, a telescopic plate is provided at the bottom of the hydraulic pump, a pneumatic cylinder is provided on the top outer wall of the piston end of the telescopic plate, a connecting block is provided on the bottom outer wall of the piston end of the telescopic plate, a fixing frame is provided on the connecting block, a displacement sensor is provided on the fixing frame, a microprocessor is provided on the top outer wall of the fixing frame, and a punch is provided at the connection between the connecting block and the fixing frame; an adaptive shape-changing mechanism: the adaptive shape-changing mechanism is provided on the guide frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] The intelligent adjustment device disclosed in this utility model for the power source of the positioning hole forming of the front subframe crossbeam is mainly used in scenarios where the power source parameters are fixed and cannot be flexibly adjusted according to different materials and specifications of the front subframe crossbeam.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 An intelligent adjustment device for a power source used for forming positioning holes in a front subframe crossbeam includes a base 1, a worktable 2, and a guide frame 3. It further includes: an intelligent adjustment mechanism: the intelligent adjustment mechanism includes a connecting frame 4 connected between two guide frames 3, a hydraulic pump 5 mounted on the connecting frame 4, a telescopic plate 9 mounted at the bottom of the hydraulic pump 5, a pneumatic cylinder 6 mounted on the top outer wall of the piston end of the telescopic plate 9, a connecting block 8 mounted on the bottom outer wall of the piston end of the telescopic plate 9, a fixing frame 10 mounted on the connecting block 8, a displacement sensor 13 mounted on the fixing frame 10, a microprocessor 11 mounted on the top outer wall of the fixing frame 10, and a punch 12 at the connection point between the connecting block 8 and the fixing frame 10; and an adaptive shape-changing mechanism: the adaptive shape-changing mechanism is mounted on the guide frame 3.

[0022] Specifically, during the processing, based on real-time feedback data, instructions are quickly processed and issued to precisely control the movement of punch 12, thereby ensuring the forming accuracy of the positioning holes of the front subframe crossbeam and reducing processing errors caused by unstable power or displacement deviation.

[0023] Among them, the microprocessor 11 adopts a high-performance industrial-grade microprocessor 11, which works in conjunction with the hydraulic pump 5, the pneumatic cylinder 6, and the punch 12.

[0024] Specifically, it can quickly process various data and instructions, and adjust the power source parameters required for forming positioning holes of front subframe crossbeams of different materials and specifications as needed. The hydraulic pump 5 is used to provide hydraulic power, with an output pressure range of 0-50MPa. The pneumatic cylinder 6 provides pneumatic power, with a working air pressure range of 0.1-1.0MPa. The power is transmitted to the punch 12 through the connecting block 8 to meet diverse processing requirements and effectively avoid positioning hole forming quality problems caused by insufficient or excessive power.

[0025] Reference Figure 1 , Figure 3 and Figure 4 In a preferred embodiment, the adaptive changing mechanism includes a rail groove 7 disposed on one side of the guide frame 3. The rail groove 7 is used in conjunction with the connecting frame 4 and forms an X / Y / Z three-axis linkage with the telescopic plate 9 and the connecting frame 4.

[0026] Specifically, through the X / Y / Z three-axis linkage structure design, the device can freely adjust the position and movement trajectory of the punch 12 in three dimensions, flexibly adapting to the processing tasks of front subframe crossbeam positioning holes with different shapes, sizes, and positional requirements. Whether it is a simple regular shape or a complex irregular positioning hole, the processing path of the punch 12 can be precisely adjusted through three-axis linkage to meet diverse production needs. When it is necessary to change to process front subframe crossbeams of different specifications, the three-axis linkage system can quickly and accurately adjust the position and related parameters of the punch 12. The cooperation between the rail groove 7 and the connecting frame 4 allows the connecting frame 4 to move flexibly on the guide frame 3, combined with the telescopic function of the telescopic plate 9. Yes, it eliminates the need for large-scale disassembly and reassembly of the equipment, significantly shortening changeover time, improving production efficiency, and reducing production downtime costs caused by changeovers. Simultaneously, the three-axis linkage system boasts high motion precision and control stability, enabling precise control of the punch 12's movement distance and speed in the X, Y, and Z directions during processing. This ensures accurate relative positioning of the punch 12 with the front subframe crossbeam, guaranteeing the machining accuracy of the positioning holes, reducing scrap and defects caused by positional deviations, improving product quality, enhancing the equipment's versatility and applicability, reducing the cost for companies to equip different products with dedicated equipment, and increasing equipment utilization and return on investment.

[0027] Among them, punch 12 adopts a servo electric spindle with a built-in torque sensor for drilling or stamping.

[0028] Specifically, the servo electric spindle has high-precision speed and position control capabilities, and can accurately adjust parameters such as rotational speed and feed rate according to different processing requirements. During drilling or stamping, it ensures that the punch 12 moves according to the predetermined trajectory and parameters, thereby effectively improving the dimensional and shape accuracy of the positioning hole and reducing processing errors. At the same time, the built-in torque sensor can monitor the torque changes of the punch 12 in real time during processing. By feeding the torque data back to the control system 15, abnormal situations in the processing process can be detected in time, such as uneven material hardness or tool wear, and adjustments can be made quickly to ensure the stability of the processing process and the processing quality of the positioning hole. The punch 12 can be used for both drilling and stamping, meeting the different forming requirements of the positioning hole of the front subframe crossbeam. Whether it is required for precise drilling or efficient stamping, it can be achieved through the flexible control of the servo electric spindle, improving the versatility and adaptability of the device.

[0029] Reference Figure 1 and Figure 3 In a preferred embodiment, a support block 14 is provided on the fixing frame 10.

[0030] Specifically, the support block 14 can better fit the crossbeam, making the fixation more secure and enhancing the structural stability. At the same time, when the punch 12 performs drilling or stamping operations, a large force will be generated. The support block 14 can disperse these forces, reduce the local stress on the fixing frame 10 and other related components, and avoid structural deformation or damage due to local stress concentration, thereby enhancing the structural stability of the entire device.

[0031] The base 1 is made of high-strength alloy steel, and the bottom of the base 1 is equipped with shock-absorbing rubber pads.

[0032] Specifically, the high-strength alloy steel material has excellent mechanical properties, enabling it to withstand the large loads generated during the operation of the device, including the weight of components such as the hydraulic pump 5 and the pneumatic cylinder 6, as well as the forces generated during the processing of the punch 12. This ensures that the base 1 can provide solid and reliable support for the entire device, guaranteeing that the device will not undergo structural deformation or damage during long-term operation and maintaining a stable processing state. The shock-absorbing rubber pad at the bottom of the base 1 has good elasticity, which can absorb and buffer the vibrations generated during the operation of the device. When the punch 12 performs drilling or stamping operations, strong vibrations are generated. If these vibrations are directly transmitted to other components of the device, they may affect the processing accuracy or even cause the components to loosen or be damaged. The stable base 1 and effective shock absorption measures provide a good foundation for the precise movement of the punch 12. Under minimal vibration, the punch 12 can perform drilling or stamping according to the predetermined trajectory and parameters, reducing positioning deviations and processing errors caused by vibration, thereby improving the processing accuracy of the positioning holes of the front subframe crossbeam and ensuring product quality.

[0033] Reference Figure 1 and Figure 2 In a preferred embodiment, a control system 15 is provided on one side of the workbench 2. The control system 15 includes a PLC and a touch screen, which receives sensor signals and feeds back adjustment commands.

[0034] Specifically, after receiving the data transmitted by the microprocessor 11, the control system 15 compares and analyzes it with preset pressure, displacement, and temperature thresholds. When the pressure value is lower than the preset pressure threshold, it indicates that the pressure in the hydraulic cylinder is insufficient, which may lead to insufficient forming of the positioning hole. When the displacement deviates significantly from the preset displacement threshold, it indicates that the movement of the piston rod does not meet the forming requirements, which will affect the dimensional accuracy of the positioning hole. When the temperature exceeds the preset temperature threshold, it may affect the performance of the hydraulic oil and the normal operation of the hydraulic cylinder. Based on the analysis results of the control system 15, a control command is issued. If the pressure value is lower than the preset pressure threshold, the microprocessor 11 issues a command to increase the speed of the hydraulic pump 5 motor and increase the output flow of the hydraulic pump 5, thereby increasing the pressure in the hydraulic cylinder. At the same time, the opening of the electromagnetic proportional valve is appropriately increased to allow more hydraulic oil to enter the hydraulic cylinder. If the displacement deviates significantly from the preset displacement threshold, the microprocessor 11 adjusts the output flow of the hydraulic pump 5 and the flow of hydraulic oil entering the hydraulic cylinder according to the direction and magnitude of the deviation, thereby controlling the movement speed and displacement of the piston rod to meet the forming requirements. If the temperature exceeds the preset temperature threshold, the microprocessor 11 adjusts the output flow of the hydraulic pump 5 appropriately according to the temperature change to avoid the hydraulic system performance from deteriorating due to excessive temperature.

[0035] Working Principle: During operation, the operator inputs the positioning hole parameters (such as hole diameter, position, and angle) of the crossbeam through the control system 15. The PLC generates the motion path, and the microprocessor 11 quickly processes and adjusts the power parameters of the hydraulic pump 5 and the pneumatic cylinder 6 according to the forming requirements of the positioning holes of the front subframe crossbeams of different materials and specifications. The hydraulic pump 5 provides hydraulic power of 0-50MPa, and the pneumatic cylinder 6 provides pneumatic power of 0.1-1.0MPa. The power is transmitted to the punch 12 through the connecting block 8 to meet diverse processing requirements. The guide groove 7 of the adaptive changing mechanism cooperates with the connecting frame 4, and together with the telescopic plate 9 and the connecting frame 4, forms an X / Y / Z three-axis linkage to process the front subframe crossbeams of different shapes, sizes, and positions. When positioning the beam, the three-axis linkage system can quickly and accurately adjust the position and movement trajectory of the punch 12 to ensure that the relative position of the punch 12 and the front subframe crossbeam is accurate, thus ensuring the machining accuracy of the positioning hole, reducing scrap and defects, improving product quality, and enhancing the versatility and applicability of the device. The punch 12 adopts a servo electric spindle with a built-in torque sensor for drilling or stamping. After receiving the data transmitted by the microprocessor 11, the control system 15 on one side of the worktable 2 compares and analyzes it with the preset pressure, displacement, and temperature thresholds. Based on the analysis results, the control system 15 issues control commands. Through the intelligent adjustment mechanism, the adaptive shape-changing mechanism, and the control system 15, the precise positioning and dynamic compensation of the power source are achieved, thereby improving the machining quality.
