[0003] Currently, the tool setting operation in the industry generally involves operators using tools such as dial indicators, edge finders, and tool setting blocks to visually observe and repeatedly fine-tune the feed by hand. After recording the coordinate data, it is entered into the CNC system to finally complete the tool setting. The tool setting process relies on the operator's experience, involving repeated trial cuts and fine adjustments, which makes manual tool setting inefficient. The tool setting time is long for a single tool, and when processing multiple tools in batches, it significantly occupies processing time and reduces equipment uptime. Summary of the Invention

[0023] Example 1 like Figure 1 As shown, the present invention provides a tool setting control device for a horizontal CNC milling machine, including a detection unit, a drive unit and a control terminal 102; The detection unit is located on the worktable 100 of the horizontal CNC milling machine. The detection unit is used to collect the position of the tool tip and cutting edge of the tool 101 of the horizontal CNC milling machine. The drive unit is located on the worktable 100 and is connected to the detection unit via a transmission. The drive unit is used to change the relative positional relationship between the detection unit and the worktable 100. The control terminal 102 is electrically connected to the control center, detection unit and drive unit of the horizontal CNC milling machine.

[0024] In this embodiment, the horizontal CNC milling machine is a CNC machining equipment with the machine tool spindle 103 arranged horizontally. Its worktable 100 is used to carry the workpiece and can move along multiple coordinate directions. The spindle 103 is used to install the rotary tool 101 and to perform cutting machining on the workpiece.

[0025] The detection unit is mounted on the worktable 100 of the horizontal CNC milling machine, meaning it is installed as an auxiliary component of the worktable 100 at a preset position on its upper surface or side. The detection unit is used to collect the position of the tool tip and cutting edge of the cutting tool 101 on the horizontal CNC milling machine. Specifically, the detection unit obtains the spatial position data of the tool tip coordinates and cutting edge contour of the cutting tool 101 mounted on the spindle 103 through a non-contact measurement method. This data is the basis for determining the precise position of the cutting tool 101 in the machine tool coordinate system.

[0026] The drive unit is also mounted on the worktable 100 and is connected to the detection unit via a transmission mechanism. The drive unit is used to change the relative position between the detection unit and the worktable 100. Specifically, the drive unit acts as the displacement actuator for the detection unit; its fixed part is mounted on the worktable 100, and its movable part is fixedly connected to the detection unit. When the drive unit operates, its movable part causes the detection unit to move relative to the worktable 100, changing the spatial position of the detection unit on the worktable 100. This displacement adjustment function allows the detection unit to adjust itself to the optimal detection position according to the different sizes and installation positions of the tool 101. For example, when detecting tools 101 of different lengths, the drive unit can move the detection unit to a detection position at an appropriate distance from the tip of the tool 101, ensuring the accuracy and reliability of the detection signal.

[0027] The control terminal 102 is electrically connected to the control center, detection unit, and drive unit of the horizontal CNC milling machine. As the core of the entire tool setting control device, the control terminal 102 is connected to the detection unit via a signal cable to receive detection data, to the drive unit via a control cable to output displacement control commands, and to the control center of the horizontal CNC milling machine via a communication interface to achieve data interaction.

[0028] When the tool setting operation is started, the control terminal 102 sends a command to the drive unit to move the detection unit to the preset detection start position; then the control terminal 102 starts the detection unit to measure and obtain the position data of the tool tip and cutting edge of the tool 101; after the control terminal 102 processes the measurement data, it transmits the calculation results to the machine tool control center through the communication interface to complete the automatic setting of the tool 101 parameters.

[0029] By setting up a detection unit, a drive unit, and a control terminal 102 on the worktable 100, the tool setting operation of the horizontal CNC milling machine tool 101 is automated. The detection unit can accurately collect the three-dimensional position data of the tool tip and cutting edge of the tool 101, the drive unit can automatically adjust the detection unit to the optimal detection position, and the control terminal 102 calculates the measurement data and directly transmits it to the machine tool control center. The entire process does not require manual intervention from the operator, eliminating the inefficient links of traditional manual tool setting that rely on experience judgment and repeated trial cuts for fine adjustment, greatly shortening the tool setting time of a single tool 101, and significantly improving the equipment utilization rate in batch processing scenarios with multiple tools 101.

[0030] According to one embodiment provided by the present invention, such as Figure 1 As shown, the detection unit includes a laser displacement sensor; A laser displacement sensor is mounted on the worktable 100, with the detection end of the laser displacement sensor facing the spindle 103 of the horizontal CNC milling machine, so as to collect the three-dimensional coordinates of the tool 101 mounted on the spindle 103 and generate an electrical signal to be transmitted to the control terminal 102.

[0031] In this embodiment, the laser displacement sensor is mounted on the worktable 100, and its specific position is adjusted by the drive unit. The detection end (i.e., the laser emission window and the receiving window) of the laser displacement sensor faces the spindle 103 of the horizontal CNC milling machine, that is, the laser beam of the sensor is directed horizontally or at a specific angle toward the tool 101 mounted on the spindle 103.

[0032] During operation, the laser displacement sensor emits a laser beam onto the surface of the tool 101. The laser beam diffuses upon contact with the tool tip or cutting edge, and the reflected light is focused by the sensor. By controlling the micro-motion of the spindle 103 in multiple directions or coordinating with the movement of the drive unit, the laser displacement sensor can acquire three-dimensional coordinate data of the tool tip and multiple measurement points on the cutting edge of the tool 101. The acquired distance and position data are transmitted to the control terminal 102 in electrical signal form via a signal cable. The control terminal 102 performs comprehensive calculations on multiple sets of data to derive the precise position parameters of the tool 101 in the machine tool coordinate system. The non-contact measurement characteristic of the laser displacement sensor ensures that there is no physical contact or wear between the tool 101 and the workpiece during tool setting, achieving high-precision non-contact measurement of the tool tip and cutting edge position, providing accurate and reliable raw data for subsequent automatic tool setting calculations. The non-contact measurement method avoids the physical contact and wear between the probe and the tool 101 in traditional contact tool setting, resulting in higher measurement accuracy.

[0033] According to one embodiment of the present invention, the control center includes a communication terminal 104; The communication terminal 104 is electrically connected to the control terminal 102.

[0034] In this embodiment, the communication terminal 104 is a communication module on the machine tool control center specifically used for data interaction with external devices. The communication terminal 104 and the control terminal 102 are physically connected through a communication cable and transmit data in accordance with the corresponding communication protocol.

[0035] During operation, the control terminal 102 sends instructions to the machine tool control center via the communication terminal 104 to obtain the current status information of the machine tool, and sends the tool setting result data to the machine tool control center after tool setting is completed. The machine tool control center records the tool setting result data for subsequent tool radius and length compensation calculations in machining. The existence of the communication terminal 104 establishes a two-way data channel between the tool setting control device and the machine tool control center. Not only can the tool setting result be received by the machine tool control center, but the machine tool control center can also feed back the tool setting process status and control authority to the tool setting control device, realizing collaborative work between the two.

[0036] According to one embodiment of the present invention, the workbench 100 is further provided with a sealing box, which is capable of rotating relative to the workbench 100.

[0037] In this embodiment, the sealing box is a box-type assembly mounted on the worktable 100, with an enclosed space inside for accommodating or protecting the components disposed therein. The bottom of the sealing box is rotatably connected to the worktable 100, allowing the sealing box to rotate relative to the worktable 100 about its own central axis. The rotation of the sealing box allows the detection unit mounted on or inside the sealing box to rotate with the sealing box, thereby changing the orientation of the detection unit in the horizontal plane. This rotational freedom allows the detection unit to detect the tool 101 from multiple angles. When it is necessary to measure different sides or specific areas of the cutting edge of the tool 101, the detection unit can be adjusted to the optimal measurement angle by rotating the sealing box, without moving the worktable 100 or the spindle 103.

[0038] According to one embodiment provided by the present invention, such as Figure 1 As shown, a rotating seat 105 is provided on the worktable 100, and a sealing box is provided on the rotating seat 105. The sealing box is rotatably connected to the worktable 100 through the rotating seat 105. Rotary seat 105 is electrically connected to the control center.

[0039] In this embodiment, the rotating seat 105 is an independent component disposed on the upper surface or side of the worktable 100. The lower end of the rotating seat 105 is fixedly installed on the worktable 100, and the upper end or rotating output end of the rotating seat 105 is fixedly connected to the bottom of the sealing box. The rotating seat 105 and the worktable 100 are positioned by bolts to ensure that the rotation axis of the rotating seat 105 is consistent with the preset reference direction of the worktable 100.

[0040] The rotating base 105 is electrically connected to the control center, meaning that the drive components and angle sensors inside the rotating base 105 are connected to the control center. The control center can send rotation commands to the rotating base 105 to control the sealing box to rotate to a specific angular position; the angle sensor built into the rotating base 105 provides real-time feedback on the current rotation angle of the sealing box, enabling the control center to precisely control the rotation and positioning of the sealing box.

[0041] During automatic tool setting, the control terminal 102 sends an angle command to the control center according to the preset tool setting program. The control center drives the sealing box to rotate to the specified angle via the rotating base 105, so that the laser displacement sensor is aligned with the tip or cutting edge of the tool 101 from the optimal direction. The angle feedback built into the rotating base 105 ensures the accuracy and repeatability of the sealing box rotation positioning, ensuring that the detection unit is in a detection posture consistent with the standard during each tool setting.

[0042] According to one embodiment of the present invention, the driving unit includes a first driving part and a second driving part; The first drive unit is located on the upper surface of the worktable 100, the second drive unit is located on the first drive unit, and the laser displacement sensor is located on the second drive unit. The first drive unit can drive the second drive unit to move along the plane of the upper surface of the worktable 100, and the second drive unit can drive the laser displacement sensor to move along the height direction of the worktable 100.

[0043] In this embodiment, the first driving unit is disposed on the upper surface of the worktable 100, that is, the first driving unit is fixedly installed on the upper surface of the worktable 100, and its overall shape is elongated or flat, extending along the length or width direction of the worktable 100. The second driving unit is disposed on the first driving unit, that is, the bottom of the second driving unit is fixedly connected to the movable part of the first driving unit, and the second driving unit moves with the movement of the first driving unit. The laser displacement sensor is disposed on the second driving unit, that is, the laser displacement sensor is installed on the movable part of the second driving unit. The first driving unit can drive the second driving unit to move along the plane of the upper surface of the worktable 100, that is, the first driving unit realizes horizontal X-axis or Y-axis movement, moving the laser displacement sensor to the target position in the horizontal plane. The second driving unit can drive the laser displacement sensor to move along the height direction of the worktable 100, that is, the second driving unit realizes Z-axis movement, moving the laser displacement sensor to the target height in the vertical direction. The combined movement of the first driving unit and the second driving unit enables the laser displacement sensor to be positioned in three-dimensional space to adapt to the needs of different sized tools 101 and different detection positions. For example, when the tool 101 is long, the second drive unit can move the sensor upward to a higher detection position; when the tool 101 has a large diameter, the first drive unit can move the sensor horizontally to a position at an appropriate distance from the side of the tool 101, providing sufficient freedom of movement for automatic tool setting of tools 101 of different specifications.

[0044] According to one embodiment of the present invention, the first driving unit includes a first slide rail, a first slide table and a first motor, and the second driving unit includes a second slide rail, a second slide table and a second motor; The first slide rail is fixed on the worktable 100, the first slide table is slidably connected to the first slide rail, and the first motor is driven to drive the first slide table to move along the extension direction of the first slide rail. The second slide rail is mounted on the first slide platform, the second slide platform is slidably connected to the second slide rail, and the second motor is driven to move the second slide platform along the extension direction of the second slide rail. The laser displacement sensor is mounted on the second slide.

[0045] In this embodiment, a first slide rail is fixedly mounted on the worktable 100. The first slide rail is a long, linear guide rail extending along the length or width of the worktable 100. Preferably, the first slide rail is a cross track. A first slide table is slidably connected to the first slide rail via a slider holder, and the first slide table can slide freely along the extension direction of the first slide rail. A first motor is driven by the first slide table. The output shaft of the first motor is connected to a lead screw via a coupling. The lead screw nut is fixed to the first slide table. When the first motor rotates, it drives the lead screw to rotate, and the lead screw nut drives the first slide table to move along the first slide rail. The first motor is preferably a servo motor, which has precise speed and position control capabilities.

[0046] Correspondingly, a second slide rail is mounted on the first slide platform, that is, the second slide rail is fixedly installed on the upper surface of the first slide platform, and its extension direction is perpendicular to the extension direction of the first slide rail, forming a cross-shaped slide platform structure. The second slide platform is slidably connected to the second slide rail via a slider, and the second slide platform can slide freely along the extension direction of the second slide rail. The second motor is driven by the second slide platform, and its transmission method is the same as that of the first drive unit (screw and nut drive). The laser displacement sensor is fixedly mounted on the second slide platform and moves synchronously with the second slide platform.

[0047] According to one embodiment of the present invention, both the first motor and the second motor are equipped with brakes.

[0048] In this embodiment, the brake is an electromagnetic braking device integrated inside the motor. Its function is to automatically lock the output shaft of the motor when the motor is powered off, preventing the motor rotor from rotating unexpectedly due to gravity, external force or vibration, thereby maintaining the stability of the slide table position.

[0049] Specifically, when the motor is powered on and working normally, the brake coil is energized, and the armature inside the brake is attracted by electromagnetic force to detach from the brake disc, allowing the motor rotor to rotate freely. When the motor is powered off or the system is stopped suddenly, the brake coil is de-energized, and the armature presses against the brake disc under the action of spring force, locking the motor rotor by friction, preventing the lead screw connected to the motor from rotating, thus locking the slide table in the current position.

[0050] In the tool setting control device of a horizontal CNC milling machine, when the tool setting operation is completed or the system is in standby mode, the brakes of the first and second motors automatically activate and lock the slide to prevent the position of the laser displacement sensor from shifting due to machine tool vibration or accidental collision, thus ensuring the positional accuracy of the sensor during the next tool setting. In the event of an unexpected power outage, the brakes can also immediately lock the motors to prevent the slide from sliding and colliding with the tool 101 or workpiece due to gravity or external forces, thus providing safety protection.

[0051] By incorporating brakes within the first and second motors, an automatic position locking function is achieved when the motors are powered off. The brakes automatically lock the motor shafts during system power failure or emergency stops, preventing accidental displacement of the slide table due to external forces or gravity. This protects the laser displacement sensor from collision damage and ensures the long-term repeatability of the sensor's position. During long-term use, the brake's locking function allows the motors to maintain the slide table position without requiring continuous power to maintain torque, reducing motor heat generation and energy consumption.

[0052] According to one embodiment provided by the present invention, such as Figure 1 As shown, a protective cover 106 is provided on the top of the spindle 103, and the protective cover 106 is hinged to the spindle 103.

[0053] In this embodiment, the protective cover 106 is a protective cover disposed on the top or side of the spindle 103 housing, used to cover and protect the spindle 103 and its associated components from contamination by chips and dust. The protective cover 106 is hinged to the spindle 103, that is, one edge of the protective cover 106 is connected to the side or top of the spindle 103 via a hinge mechanism, allowing the protective cover 106 to be flipped open or closed relative to the spindle 103 around the hinge axis. In the closed state, the protective cover 106 covers the top and side of the spindle 103, preventing chips splashed during machining from entering the critical areas of the spindle 103; in the open state, the protective cover 106 flips up, exposing the spindle 103 area, facilitating tool clamping 101, spindle 103 maintenance, and tool setting operations by the operator.

[0054] During tool setting, the protective cover 106 can be pre-flipped open, ensuring that the tool 101 on the spindle 103 is fully exposed to the detection range of the laser displacement sensor, preventing it from being obstructed or interfering with the measurement optical path. After tool setting is complete, the protective cover 106 can be closed again, providing continuous protection for the spindle 103 during machining.

[0055] In one alternative implementation, the flip drive of the protective cover 106 is electrically connected to the machine tool's control center, and the protective cover 106 automatically opens when the tool setting program is started and automatically closes when machining begins.

[0056] By installing a protective cover 106 on top of the spindle 103, which is connected to the spindle 103, effective protection of the spindle 103 area and convenient access during tool setting are achieved. The protective cover 106 protects the spindle 103 from chip contamination during machining, extending the service life of the spindle 103; during tool setting, the protective cover 106 can be easily flipped open, allowing the tool 101 to be fully exposed to the measurement range of the detection unit, ensuring that the detection optical path is not obstructed or interfered with.

[0057] Example 2 This invention provides a method for using a tool setting control device, which includes the following steps: Step 1: Initialization settings for the horizontal CNC milling machine; Step 2: The detection unit detects the tip and cutting edge of the tool 101 and acquires the three-dimensional coordinates of the tool 101; Step 3: The control terminal 102 calculates the deviation of the tool 101 and transmits the compensation value to the control center; Step four: Tool setting complete.

[0058] In this embodiment, the method of using the tool setting control device applies the aforementioned tool setting control device to perform automatic tool setting operations on a horizontal CNC milling machine. The method includes the following steps: Step 1: Start the machine tool and complete the zero-return operation of each motion axis, so that the spindle 103 and the worktable 100 return to the reference zero point of the machine tool coordinate system; install the tool 101 to be set on the spindle 103 and confirm that the tool 101 is clamped in place; select the tool setting program mode to be executed through the control terminal 102 of the tool setting control device or the human-machine interface of the machine tool control center; send instructions to the drive unit to drive the first drive unit and the second drive unit to move the laser displacement sensor to the preset detection start position.

[0059] Step two: The control terminal 102 sends a command to the machine tool control center to make the spindle 103 rotate at a preset speed or remain stationary; the laser displacement sensor emits a laser beam onto the surface of the tool 101, and sequentially measures the spatial position of the tool tip and the position data of multiple feature points on the cutting edge; during the measurement process, the control terminal 102 can drive the sealing box to rotate through the rotating seat 105 to change the measurement angle of the sensor and realize the full circumference measurement of the tool 101; the sensor converts the distance data of each measurement into an electrical signal and transmits it to the control terminal 102; the control terminal 102 calculates the three-dimensional spatial coordinates of each measurement point based on the sensor position data, the spindle 103 position data and the sensor measurement values.

[0060] Step three: The built-in calculation program of the control terminal 102 compares the three-dimensional coordinates of each feature point of the tool 101 obtained in step two with the preset tool 101 standard model or the previous tool setting data, and calculates the deviation of the actual size parameters of the tool 101 (such as tool 101 length, tool 101 diameter, etc.) from the theoretical values. The control terminal 102 converts these deviations into the compensation value format required by the machine tool 101 compensation system, and transmits the compensation data to the machine tool control center through the communication terminal 104. The control center automatically updates the tool 101 length compensation and tool 101 radius compensation parameters corresponding to the tool 101 number.

[0061] Step four: Control terminal 102 sends a tool setting completion signal to the machine tool control center, and the machine tool control center confirms that the tool 101 compensation parameters have been successfully updated; Control terminal 102 sends a command to the drive unit to move the laser displacement sensor to a safe standby position; Protective cover 106 automatically closes and resumes machining state; Machining of the workpiece begins.

[0062] The above method achieves fully automated tool setting for the horizontal CNC milling machine tool 101. The operator only needs to clamp the tool 101 and select the program in step one; subsequent detection, calculation, data transmission, and parameter updates are all completed automatically under the control of the control terminal 102, requiring no manual intervention and significantly reducing the tool setting time for a single tool 101. The automated tool setting process eliminates errors caused by differences in experience-based judgment and operating techniques in traditional manual tool setting, significantly improving tool setting accuracy and consistency. Compensation values ​​are automatically transmitted to the control center and tool 101 parameters are automatically updated, avoiding transcription errors that may occur when manually entering coordinate data. This method is particularly suitable for batch processing scenarios with multiple tools 101, allowing multiple tools 101 to continuously and sequentially complete automatic tool setting, significantly improving equipment uptime and production efficiency.

[0063] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
