This application relates to a high-precision tool-unfolding mechanism with a high-power built-in drive, comprising a rotating frame, a tool head slidably mounted on the rotating frame, and a drive assembly that drives the tool head to reciprocate radially. The drive assembly includes a lead screw and a sliding block. The two ends of the lead screw are rotatably connected to the rotating frame, and the sliding block is threadedly connected to the lead screw and fixes the tool head. The drive assembly also includes a drive source and a transmission structure. The drive source drives the lead screw to rotate through the transmission structure. A mounting cavity is provided in the middle of the rotating frame, and the drive source is located in the mounting cavity. This application integrates the drive motor into the rotation center of the rotating frame, fundamentally eliminating the mass eccentricity caused by an externally mounted motor. This makes the center of gravity closer to or even coincident with the axis of rotation, greatly improving the dynamic balance and stability during high-speed rotation. The built-in layout makes the structure more compact, facilitating the selection of a higher-power drive motor, obtaining stronger driving force and more sensitive tool head adjustment, and significantly improving transmission accuracy and processing efficiency.

[Solution] The processing apparatus comprises a blade, a rotating mechanism rotatable around a rotation axis, and a holding member. The blade is mounted on the rotating mechanism by the holding member, which clamps a portion of the blade. The blade has a plurality of recesses, each smaller in depth than the blade's thickness, and each of the recesses extends from the rotation axis side to the outer circumference, spanning the portion clamped by the holding member. Liquid is supplied from the outside to a space that is at least partially surrounded by the holding member, on the rotation axis side of the position where the portion of the blade is clamped. The liquid supplied to the space is injected into each of the plurality of recesses on the rotation axis side of the portion of the blade.

In order to detect a workpiece supplied to a spindle (presence or absence of a workpiece and a length of the workpiece) without using torque fluctuation of a servo-equipped actuator, a workpiece detection device (30) includes an ejector rod (22) that is disposed inside a rear spindle (20) that grips a workpiece (W) and that is movable so as to press the workpiece (W) and eject the workpiece (W) to outside; a servo motor (28) including a drive portion (28a) that moves the ejector rod (22) and an encoder (28b); and a control portion (60) that controls the drive portion (28a) based on a detection result of the encoder (28b). The control portion (60) moves the ejector rod (22) to a standby position. The encoder (28b) detects movement when the workpiece (W) moves the ejector rod (22). The control portion (60) calculates presence or absence of the workpiece (W) based on the movement.

This utility model discloses a CNC lathe turret with an overload protection structure, including a mounting base. A cylinder is fixedly installed in the middle of the top of the mounting base. This CNC lathe turret with an overload protection structure monitors the torque force of the tool head and other structures during operation using a torque sensor. When the torque force reaches the maximum preset value, the torque sensor feeds the information back to the control panel, thereby controlling the turret structure to stop working and activating an alarm that flashes red light and sounds a buzzer, thus reminding the operator of torque overload and requiring immediate action. The cylinder pushes the mounting plate up and down, thereby moving the turret body up and down, adjusting the height of the turret until the distance between the mounting plate and the mounting base reaches the preset value of the displacement sensor. At this point, the displacement sensor feeds the information back to the control panel, controlling the cylinder to stop working, thus achieving precise adjustment of the turret height.

This application relates to a high-precision, high-stability tool unloader, comprising a tool unloader body, a tool unloader slide, and a drive mechanism. The tool unloader slide holds a cutting tool. The tool unloader body includes a main body and a tool unloader rotating body rotatably connected to the main body.
