Description

Technical Field

[0001] This invention relates to the field of tungsten carbide grinding head processing technology, specifically to a CNC machine tool for processing tungsten carbide grinding heads. Background Technology

[0002] In the field of precision machining of hard materials, especially for grinding and forming special alloy materials such as tungsten steel with high hardness and high wear resistance, extremely stringent requirements are placed on the precision, rigidity, and automation level of machining equipment. As the core equipment of modern manufacturing, CNC machine tools directly determine the machining quality and efficiency of complex, high-precision workpieces. Traditional tungsten steel grinding head machining often relies on general-purpose machine tools with special tooling, or specialized equipment with low automation levels. This results in problems such as low clamping efficiency, difficulty in ensuring positioning accuracy, poor consistency in the machining process, high dependence on operator skills, and difficulty in adapting to the needs of flexible production with multiple varieties and small batches.

[0003] In existing technologies, the key to achieving high-precision and high-efficiency workpiece machining lies in two core subsystems: one is the displacement mechanism that drives the worktable and workpiece to achieve precise and stable feed motion; the other is the fixture system that ensures the workpiece is reliably, quickly, and without damage during machining. In some existing machine tool designs, there is still room for optimization in the transmission chain design, guide structure rigidity, and closed-loop control strategy of the displacement mechanism. For example, improper design of the lead screw support method and slider guide structure may lead to transmission errors or insufficient rigidity, affecting the final machining accuracy. Meanwhile, in terms of workpiece clamping, traditional mechanical or pneumatic fixtures have limitations in clamping force control accuracy, adaptability, and stability in clamping irregularly shaped workpieces. They cannot meet the requirements of machining hard and brittle materials such as tungsten steel, which requires both large and stable clamping forces to prevent movement and avoid excessive clamping forces that could cause workpiece deformation or damage.

[0004] Furthermore, with the development of intelligent manufacturing, the integrated and intelligent control of machine tools has become a trend. A fully functional CNC system not only needs to precisely coordinate the movements of each motion axis, but also needs to integrate precise control of hydraulic fixtures, and possess user-friendly human-machine interaction, status monitoring, and data exchange capabilities. Existing machine tool controllers still have potential for improvement in terms of modular design, deep integration and coordination of various control units (such as axis motion control and fixture control), and real-time status feedback and closed-loop adjustment, in terms of their systemic and intelligent levels. No solutions have yet been proposed to address these related technical issues. Summary of the Invention

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] Example Please see Figure 1-2This invention proposes a technical solution for a CNC machine tool for machining tungsten carbide grinding heads: A CNC machine tool for machining tungsten carbide grinding heads includes a machine tool body 1, a worktable 2 connected to the machine tool body 1 via a displacement mechanism, a controller 3 disposed on one side of the machine tool body 1, a pressure fixture disposed on the worktable 2, the displacement mechanism including a drive motor 4, a reducer 5, a screw 6, and a guide slider 7, the drive motor 4 being fixedly mounted on the machine tool body 1, the drive motor 4 being fixedly connected to one end of the screw 6 via the reducer 5, the other end of the screw 6 being movably connected to the machine tool body 1, and the top end of the guide slider 7 being connected to the worktable 2. The bottom side of the worktable 2 is fixedly connected, and one end of the bottom of the guide slider 7 is sleeved on the screw 6 and threadedly connected to the screw 6. The bottom sides of the worktable 2 are movably connected to the machine tool body 1. Specifically, the displacement mechanism can precisely adjust the position of the worktable 2. The drive motor 4 is started, which drives the screw 6 connected through the reducer 5 to rotate clockwise or counterclockwise. When the screw 6 rotates, it drives the guide slider 7 connected to the screw to move, thereby adjusting the position of the worktable 2. The pressure can fix the raw material of the tungsten carbide grinding head. The controller 3 can realize intelligent control, improve the processing accuracy, and reduce manual operation. The clamping fixture includes a support plate 9, a base 10, a hydraulic cylinder 11, a connecting plate 12, and a positioning plate 13. The support plate 9 is set on the top of the worktable 2. Several bases 10 are set on both sides of the top of the support plate 9. The hydraulic cylinder 11 is installed on the base 10. The output end of the hydraulic cylinder 11 is movably connected to one side of the positioning plate 13. The two ends of the connecting plate 12 are movably connected to the base 10 and the positioning plate 13, respectively. Specifically, the support plate 9 plays the role of supporting the whole, and the base 10 can support the hydraulic cylinder 11, the connecting plate 12, and the positioning plate 13. There are six bases 10, which are symmetrically distributed. By pushing the positioning plate 13 through the hydraulic cylinder 11, combined with the lever action of the connecting plate 12, a large and stable clamping force can be generated. This not only can the magnitude and stroke of the clamping force be precisely controlled, but also avoids the workpiece loosening due to insufficient clamping force or deformation and damage to the workpiece due to excessive clamping force.

[0019] Please see Figure 1-2 As shown, further, the top of the workbench 2 is provided with several fixing slots 14, and screws 15 are provided on the fixing slots 14. Fixing openings 16 are provided on both sides of the support plate 9. One end of the screw 15 passes through the fixing opening 16 and extends to the top of the fixing opening 16, and the end is threaded with a nut 17.

[0020] In this embodiment, the support plate 9 is detachably connected to the worktable 2 by screws 15 and nuts 17, which improves convenience and allows the position of the clamp to be flexibly adjusted according to the workpiece size, thereby enhancing the process adaptability of the machine tool and realizing fast, reliable and adaptive workpiece clamping.

[0021] Please see Figure 1-2As shown, guide rails 18 are fixedly installed on both sides of the top of the worktable 2, and sliding blocks 8 are movably connected to the guide rails 18. The top of the sliding blocks 8 is fixedly connected to the bottom of the worktable 2.

[0022] In this embodiment, when the worktable 2 moves under the action of the displacement mechanism, it drives the sliding block 8 to move on the guide rail 18 on the worktable 2, thereby improving the stability of the movement of the worktable 2.

[0023] Furthermore, controller 3 includes: The core processing module is used to execute CNC program instructions, perform motion trajectory interpolation calculations, and perform logic control. The axis motion control module is electrically connected to the core processing module and is used to receive control commands and drive the drive motor 4 to precisely control the linear feed motion of the worktable 2. The clamping control module is electrically connected to the core processing module and is used to control the action of the hydraulic cylinder 11 to clamp and release the workpiece. The human-machine interaction module is electrically connected to the core processing module and is used to receive operator input commands and display machine tool status information. Power supply and drive module, used to provide stable power.

[0024] Furthermore, the axis motion control module includes: The motor drive unit is used to generate the power signal to drive the drive motor 4; The position feedback unit is used to collect the actual position information of the displacement mechanism and feed it back to the core processing module to form a closed-loop control.

[0025] In this embodiment, the motor drive unit receives speed and position commands from the core processing module and converts them into current or voltage signals (power signals) required to drive the motor 4 (servo motor or stepper motor) through a power amplifier (such as a servo driver). This controls the torque, speed, and direction of the drive motor 4, which is the foundation for achieving precision motion. The position feedback unit collects the actual position information of the worktable 2 or screw 6 in real time and continuously through sensors (such as high-precision grating rulers, rotary encoders, etc.) installed on the displacement mechanism, and feeds this information back to the core processing module at high speed in the form of digital signals. The core processing module compares this actual position with the commanded position, calculates the following error, and performs dynamic correction through the motor drive unit, thereby eliminating position deviations caused by transmission errors, load changes, and other factors, ensuring the positioning accuracy and repeatability of the worktable.

[0026] Furthermore, the press control module includes: The hydraulic control unit is used to output control signals to the hydraulic valve group to adjust the pressure and stroke of the hydraulic cylinder 11; The clamping status detection unit is used to detect the clamping status of the positioning pressure plate 13 and feed the signal back to the core processing module.

[0027] In this embodiment, the hydraulic control unit outputs precise electrical signals to the hydraulic cylinder 11 according to the instructions (such as clamping, releasing, and pressure setting) of the core processing module. By controlling the flow direction, flow rate, and pressure of the hydraulic oil, it achieves precise and stepless adjustment of the extension / retraction (stroke) and output force (pressure) of the piston rod of the hydraulic cylinder 11. This ensures that the clamping force can firmly fix high-hardness workpieces such as tungsten steel, while avoiding workpiece deformation or damage due to overload. The clamping status detection unit monitors the pressure value of the hydraulic cylinder 1 and the position or whether the positioning plate 13 is in place in real time through pressure sensors, displacement sensors, or proximity switches. The detection signals are fed back to the core processing module to determine whether clamping is completed and whether the clamping force is within the set range. It can also realize alarms and safety interlocks for abnormal states (such as clamping failure) to ensure the safety and reliability of the processing process.

[0028] Furthermore, the human-computer interaction module includes: The display unit is used to display the machining program, coordinate position, alarm information and operation menu; The input unit, including physical buttons, knobs, and a touchscreen, is used to input operation commands and parameters.

[0029] In this embodiment, the display unit uses a liquid crystal display (LCD) or an industrial touch screen to display in real time: the currently executed machining program segment, the actual and commanded positions of each coordinate axis, spindle speed, feed rate, system alarm information, operation prompt menu, machine tool status (running, paused, alarm), etc.; the input unit provides a variety of command input methods: physical buttons and knobs are used for emergency stop, mode selection (automatic / manual / handwheel), axis jogging, magnification adjustment and other common operations that require fast response or tactile feedback; the touch screen provides a graphical and menu-driven operation interface for complex inputs such as program editing, parameter setting, file management, and graphic simulation, making operation intuitive and convenient.

[0030] Furthermore, controller 3 also includes: The communication module is used to realize data communication between the controller 3 and the host computer and external network; The storage module is used to store system parameters, machining programs, and historical machining data.

[0031] In this embodiment, the communication module supports standard industrial communication protocols such as Ethernet, RS-232, RS-485, and USB, enabling data exchange and command communication with a host computer (for CAD / CAM programming, remote monitoring, and production management), external networks (for workshop-level DNC program transmission and data acquisition), or other intelligent devices (such as robots and measuring instruments). The storage module stores the machine tool's mechanical parameters (such as lead screw pitch and backlash compensation value), servo parameters, PLC parameters, etc., and stores NC programs for multiple workpieces to be processed. It can record important operation logs, alarm history, and processing quantity statistics, which facilitates fault diagnosis and production analysis. It uses solid-state storage (such as Flash memory), which features fast read / write speed, vibration resistance, and high reliability.

[0032] Working principle of the invention: After power is connected, the power supply and drive module of controller 3 provides stable power to each module, the system starts, the core processing module loads the system parameters in the storage module, and controls each module to perform self-checks to confirm that the displacement mechanism, pressure fixture, and sensor are in normal condition. The operator calls or edits the machining program (NC program) to be processed through the input unit (touch screen, buttons, etc.) of the human-machine interface module, and sets or confirms the machining parameters (such as feed rate, spindle speed, clamping force, etc.). The program and parameters are stored in the storage module and can be obtained from an external computer or network through the communication module. The tungsten carbide grinding head blank to be processed is placed in the preset area of ​​the support plate 9 on the worktable 2. According to the instructions, the pressure fixture control module outputs a signal through its hydraulic control unit to drive the hydraulic cylinder 11. When the hydraulic cylinder 11 piston rod extends, it pushes the positioning pressure plate 13 and applies clamping force evenly and stably to the workpiece through the lever action of the connecting plate 12). The clamping state detection unit monitors the clamping force or the position of the pressure plate in real time and feeds back the confirmation signal to the core processing module. After ensuring reliable clamping, it enters the processing preparation state. The support plate 9 is connected to the fixing groove 14 and fixing opening 16 of the worktable 2 through screws 15 and nuts 17, which allows the overall position of the press to be flexibly adjusted according to the size of the workpiece, reflecting the process adaptability of the device.

[0033] After the automatic machining program is started, the core processing module reads the CNC instructions from the storage module, performs high-speed analysis and motion trajectory interpolation calculation, and generates a precise position and speed instruction sequence for the worktable 2 during the machining process. The axis motion control module receives the motion instructions from the core processing module, and the motor drive unit converts the digital instructions into high-precision analog power signals to drive the drive motor 4) to operate according to the set torque, speed, and direction. The output torque of the drive motor 4 is amplified and speed-adjusted by the reducer 5 and then transmitted to the screw 6 to produce precise rotational motion. The rotation of the screw 6 is controlled by the interaction with the guide slider 7. The threaded engagement is converted into precise linear motion of the guide slider 7 and the worktable 2 fixed thereto. At the same time, the sliding block 8 at the bottom of the worktable 2 slides along the guide rail 18 fixed on the machine tool body 1, forming a high-rigidity, low-friction composite guide system together with the screw 6 transmission pair, ensuring smooth and wobbly movement. The position feedback unit collects the actual position information of the screw 6 or the worktable 2 in real time through high-precision sensors (such as encoders and grating rulers) and immediately feeds it back to the core processing module. The core processing module compares the actual position with the command position, calculates the position error, and dynamically adjusts the output of the drive motor 4 through the axis motion control module to form a fast closed-loop control system. This process continues, effectively compensating for the effects of transmission chain errors, thermal deformation, and load changes, thereby ensuring that the linear feed motion of the worktable 2 achieves micron-level or even higher positioning accuracy and repeatability. While controlling the motion, the core processing module coordinates and controls the start and stop, speed, and cooling system of the spindle (not shown in the figure, usually mounted on the machine tool body to grind or mill the workpiece) according to the program logic, so that the tool (grinding head) and the workpiece complete the predetermined contour grinding or shaping process under the precise feed of the worktable.

[0034] When the machining program is completed, the core processing module issues an instruction, and the hydraulic control unit of the pressure control module controls the hydraulic cylinder 11 to reverse, so that the positioning pressure plate 13 releases its grip on the workpiece. The clamping status detection unit confirms that the workpiece is released in place, and the axis motion control module drives the drive motor 4 to move the worktable 2 to a safe position (such as the initial position) that is convenient for the operator to load and unload the workpiece. Key information in the entire machining process (such as machining time, alarm records, machining quantity, etc.) is recorded by the storage module.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
