Description

Technical Field

[0001] This invention belongs to the field of automotive parts manufacturing technology, and specifically relates to a stabilizer bar pressure head drilling control system based on a dual-position drilling rig. Background Technology

[0002] The stabilizer bar is one of the core components of a car's suspension system, such as... Figure 3 As shown, its structure is U-shaped, including a crossbar 19 and stabilizer arms 18 integrally formed with the crossbar 19 and located at both ends of the crossbar 19. The connecting end of the stabilizer arm 18, usually referred to as the pressure head 20, needs to be stamped and drilled to ensure its connection strength and assembly accuracy. Its function is to suppress body roll when the vehicle is turning through its own torsional characteristics, thereby significantly improving the vehicle's handling stability and driving safety, which is crucial to vehicle performance and driving safety.

[0003] However, most existing drilling control systems use pre-set, fixed processing parameters for programmed control. This control method cannot adapt to the many variables in actual production. Specifically, after the initial stamping and heat treatment, the surface and internal hardness of the stabilizer bar indenter inevitably fluctuates; furthermore, during drilling, the drill bit gradually wears down, causing changes in its cutting performance; in addition, different batches of raw materials may have performance differences. These changing working conditions make it difficult for fixed processing parameters to always be in optimal condition. When the material hardness does not match the parameter settings, it will lead to low processing efficiency, and even problems such as drill bit chipping and excessive hole wall roughness; and when the drill bit wears down, if the parameters are not adjusted in time, the increased cutting force can easily lead to inaccurate hole diameter and hole position deviation, and in severe cases, workpiece deformation or tool breakage.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme, design method and advantages of the application more clear and explicit, the application is further described in detail below by specific embodiments combined with the drawings. It should be understood that the specific embodiments described herein are only used to explain the application and do not limit the application.

[0020] Example 1 As Figure 1 And Figure 5 The present application provides a stable rod pressure head drilling control system based on a two-bit drilling platform, which is connected to a stable rod pressure head drilling device. Specifically, the stable rod pressure head drilling device includes a bed body 1 and a drilling platform assembly symmetrically arranged on the bed body 1. Two drilling platform assemblies are used to fix two pressure heads 20 of a stable rod 17 and drill holes in the pressure heads 20. The control system includes a memory 21 and a processing module 22 connected in communication. The processing module 22 acquires a first parameter set and a first preset value in response to a drilling task. The first parameter set and the first preset value are input to a drilling mechanism model 26, which outputs a first control signal. Based on the first control signal, a first execution instruction is generated and executed to adjust the feed speed of the drilling platform assembly, the rotation speed of the drill bit 13, and the reciprocating frequency of the drill bit 13. In this embodiment, the first parameter set includes real-time feed resistance and pressure head surface hardness. The first preset value includes drilling depth, hole diameter accuracy, and hole wall finish. To ensure that the stable rod 17 is balanced in the machining process and avoid deformation caused by asymmetric machining, the control system is configured to control the two drilling platform assemblies simultaneously or independently. The processing module 22 also includes a cooperative control unit 30 for ensuring that the drilling operations of the two pressure heads 20 are synchronized in parameters or executed in a preset logical order. The processing module 22 acquires multi-source sensing data through a real-time industrial network and makes multi-parameter fusion decisions in the drilling mechanism model 26.

[0021] The drilling mechanism model 26 is composed of a resistance analysis unit 27, a precision analysis unit 28, and a task management unit 29. The task management unit 29 serves as the drilling mechanism model 26 scheduling core, the parameter acquisition unit 31 directly accesses the sensor data buffer through shared memory, and the resistance analysis unit 27 and the precision analysis unit 28 are respectively deployed on the GPU and NPU of the processing module 22, and the inference process is accelerated through CUDA and TensorRT. The neural network unit adopts a hierarchical architecture, the input layer receives standardized sensor data, the hidden layer contains three fully connected layers, and the output layer generates control parameters. In the model training stage, the network weights are optimized through the batch gradient descent algorithm, and the loss function adopts a composite form of mean square error and regularization term. The resistance analysis unit 27 adopts a convolutional neural network structure, which is specially designed to extract time-domain features of the feed resistance. Through multi-layer convolution kernels, multi-scale features of the signal are extracted to establish a nonlinear mapping between resistance and feed speed. The precision analysis unit 28 is based on a deep belief network, which learns the complex relationship between hardness, spindle speed and machining quality. The task management unit 29 ensures real-time based on the priority scheduling principle. When building the model, a large number of resistance-feed speed pairs, hardness-spindle speed pairs, and finish-reciprocating frequency pairs are collected, marked by artificial experts, and then input into different neural network units for iterative training. Finally, the trained neural network units 32 are combined to form a complete model. When working, the task management unit 29 schedules the drilling task, configures the parameter acquisition unit 31 to match the corresponding training resources, supports the resistance analysis unit and the precision analysis unit to analyze the feed speed and spindle speed, and outputs the first control signal. Among them, the resistance-feed speed pair is related to different real-time feed resistance and corresponding spindle feed speed, the hardness-spindle speed pair is related to different indenter surface hardness and corresponding drill spindle speed, and the finish-reciprocating frequency pair is related to different hole wall finish requirements and corresponding drill depth direction reciprocating frequency.

[0022] With continued reference to Figure 1In the above, the drill table assembly is arranged along the bed 1 in sequence as follows: spindle box 4, Z-axis fixed cylinder 6, and X-axis fixed cylinder 8. The spindle box 4 is installed at the end of the bed and slidably connected to it. A drill bit 13 is installed at the output end, and the internal spindle drives the drill bit to rotate. The bottom of the Z-axis fixed cylinder 6 is connected to the support plate 2 via a fixed base 5. The support plate is fixed to the bed, and the V-shaped support block 12 on the support plate corresponds to the position of the Z-axis cylinder output end, allowing the cylinder output end to abut the pressure head 20 against the V-shaped support block. The X-axis fixed cylinder 8 is fixed to the slide table 3 via a support frame 7. The slide table is connected to the bed, and the adjusting plate 10 on the slide table is fixed with bolts. The limiting plate 11 on the adjusting plate is adapted to the X-axis cylinder output end, allowing the cylinder output end to abut the stabilizer bar 19 against one side of the limiting plate. In the control system, the processing module 22 is associated with the spindle box, cylinders, and other actuators to achieve precise control of the structural movements. The sliding design between the spindle box 4 and the bed 1 ensures the drilling feed stroke. The Z-axis fixed cylinder 6 and the X-axis fixed cylinder 8 cooperate with the V-shaped support block 12 and the limiting plate 11 from the vertical and horizontal directions respectively to form a bidirectional positioning structure. This can quickly fix the stabilizing rod and limit its displacement, providing a stable mechanical foundation for synchronous drilling in two stations and preventing the workpiece from moving during the processing.

[0023] The drill bit 13 is connected to the spindle inside the spindle box 4 via a coupling. A torque sensor 23 is installed on the coupling, which communicates with the processing module 22. The processing module converts the sensor signal into a real-time feed resistance signal. A hardness detection probe 24 is installed on the V-shaped support block 12, which is connected to the processing module and transmits the surface hardness parameters of the indenter. The data from both together constitute the first parameter set input to the drilling mechanism model 26. Figure 2 As shown, a slider 14 is provided at the bottom of the spindle box 4, and a lead screw 15 is connected to the output end of the drive box 16 at the bottom of the bed 1. The lead screw passes through the slider and is threadedly connected to the slider. The processing module is connected to the drive box and the spindle motor in the spindle box respectively, controlling the spindle box movement speed (i.e., feed speed) and drill rotation speed. When the drilling reaches the preset depth, the processing module controls the spindle box to perform reciprocating motion at a specific frequency to achieve drill chip removal and hole wall finishing. The torque sensor 23 and the hardness detection probe 24 realize the accurate acquisition of real-time working parameters, providing data support for model parameter adjustment. The threaded transmission structure of the lead screw 15 and the slider 14 ensures the stability and accuracy of the feed of the spindle box 4. The processing module 22 integrates the control of feed speed, rotation speed and reciprocating motion, realizing dynamic adaptation of processing parameters and solving the drilling chip removal problem through reciprocating motion, thus improving the hole wall processing quality.

[0024] The processing module 22 communicates with the Z-axis fixing cylinder 6 and the X-axis fixing cylinder 8. When drilling begins, it controls the Z-axis cylinder output end to extend, bringing the pressure head 20 against the V-shaped support block 12 to complete Z-axis positioning. Simultaneously, it controls the X-axis cylinder output end to extend, using the end V-shaped plate 9 to bring the crossbar 19 against the limiting plate 11 to complete X-axis positioning. After drilling ends, it controls the Z-axis fixing cylinder 6 and the X-axis fixing cylinder 8 to retract sequentially to release the clamping force. Pressure sensors 25 are installed on the piston rods of both the Z-axis fixing cylinder 6 and the X-axis fixing cylinder 8, connected to the processing module and monitoring the clamping force in real time. The processing module compares the real-time clamping force with a preset value; if it exceeds the range, it pauses drilling or issues an alarm and adjusts the cylinder output pressure to the preset value. The V-shaped plate 9 at the output end of the X-axis fixing cylinder 8 has its V-groove facing the limiting plate 11, adapting to the shape of the crossbar for a snug fit and fixation.

[0025] Example 2 Based on Example 1, this example discloses a method for drilling holes in a stabilizer bar indenter, including: like Figure 5 As shown, the operator places the stabilizing rod 17 on the bed 1, so that the indenters 20 at both ends correspond to the V-shaped support blocks 12 on the two drilling rig assemblies. At the same time, the crossbar 19 of the stabilizing rod is placed in the area between the V-shaped plate 9 and the limiting plate 11 of the X-axis fixing cylinder 8. After placement, the processing module 22 activates the hardness detection probe 24 installed on the V-shaped support block 12 to quickly detect the surface hardness of the indenter 20, and stores the hardness parameter as part of the first parameter set in the memory 21, preparing for subsequent intelligent parameter adjustment.

[0026] According to preset logic, the processing module 22 simultaneously issues commands to activate the Z-axis fixing cylinder 6 and the X-axis fixing cylinder 8 at the two workstations. The output end of the Z-axis fixing cylinder 6 extends, precisely abutting the pressure head 20 of the stabilizer rod 17 against the V-shaped support block 12, completing the Z-axis positioning; simultaneously, the output end of the X-axis fixing cylinder 8 extends, using the V-shaped plate 9 at its end to press the stabilizer rod crossbar 19 against one side of the limiting plate 11, completing the X-axis positioning. During this process, the pressure sensor 25 integrated on the cylinder piston rod monitors the clamping force in real time and feeds the data back to the processing module 22. The processing module 22 compares the real-time clamping force with the preset safe clamping force range in the memory 21, dynamically adjusts the cylinder output pressure, forming a force closed-loop control to ensure that the clamping force is sufficient to prevent the workpiece from shifting without damaging or deforming it.

[0027] After clamping is completed, the processing module 22 sends a start command to the spindle motor in the drive box 16 and the spindle box 4. The drive box 16 drives the lead screw 15 to rotate, causing the spindle box 4, which meshes with the lead screw through the slider 14, to feed towards the pressure head 20; at the same time, the spindle motor drives the drill bit 13 to rotate at high speed. Specifically, the torque sensor 23 installed on the spindle coupling collects the feed resistance signal in real time, as another key input of the first parameter set. The parameter acquisition unit 31 of the processing module 22 inputs the real-time feed resistance signal and the pre-stored pressure head surface hardness parameter, along with the first preset values ​​(drilling depth, hole diameter accuracy, hole wall smoothness), into the drilling mechanism model 26 pre-stored in the memory 21. The resistance analysis unit 27 and the accuracy analysis unit 28 inside the model perform rapid calculations under the scheduling of the task management unit 29, and output the optimal first control signal. The processing module 22 adjusts the feed speed of the spindle box 4 and the rotation speed of the drill bit 13 in real time and adaptively. When the system determines that drill bit 13 has reached the predetermined drilling depth, processing module 22 will also control spindle box 4 to perform reciprocating motion at a specific frequency to achieve intelligent chip removal and hole wall finishing. The entire process is ensured by the coordination control unit 30 to synchronize the actions of the two drill rig components and ensure the workpiece is subjected to force balance.

[0028] After the drilling task reaches the preset requirements, the processing module 22 controls the drill bit 13 to stop rotating and instructs the drive box 16 to reverse, retracting the spindle box 4 to its initial position via the lead screw 15. Subsequently, the processing module 22 controls the X-axis fixing cylinder 8 and the Z-axis fixing cylinder 6 to retract sequentially according to a preset sequence, completely releasing the clamping of the stabilizer bar 17. The operator can then safely remove the finished, consistent-quality stabilizer bar, completing a single, efficient, and intelligent drilling process.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
