This utility model provides a high-efficiency punching machine with a built-in burr removal component, comprising: a machine base, a vertical support fixedly installed on the top of the machine base, a punching mechanism and a clamping mechanism respectively provided on the top and side walls of the vertical support, a partition fixedly installed inside the machine base, and a guide mechanism above the partition; a sleeve fixedly installed in the middle of the machine base, a piston slidingly sealed inside the sleeve, the top of the piston being rotatably connected to a gear shaft, and a transmission mechanism provided at the bottom of the partition. This application uses a grinding head inside the machine base to remove burrs after punching the workpiece, enabling rapid processing of burrs on the bottom edge of the hole after punching, solving the problem of needing to flip the workpiece before processing. The grinding head is moved using a liftable and rotatable gear shaft, which does not conflict with the punching operation and does not affect the unloading of residual material during punching for convenient subsequent processing. After punching, the grinding force of the grinding head is controlled by air pressure to achieve efficient burr removal and improve the performance of the punching machine.

A fresh tea leaf harvester includes a receiving box, a mounting frame, a reciprocating cutter assembly, a movable cutter, a cutting force adjustment assembly, and a pull-blade assembly. The mounting frame is disposed inside the receiving box. The reciprocating cutter assembly is movably mounted on the mounting frame. The movable cutter is movably mounted on the mounting frame and its cutting portion is serrated with that of the reciprocating cutter assembly. The cutting force adjustment assembly is movably mounted on the mounting frame, with its actuators distributed on both sides of the movable cutter's mounting portion. The actuators of the cutting force adjustment assembly cooperate with the movable cutter to adjust the maximum cutting force. The pull-blade assembly is disposed on the mounting frame and distributed on both sides of the movable cutter's mounting portion. The pull-blade assembly includes a displacement amplification assembly, a return spring, a magnet, and a magnetic shielding assembly. By setting the cutting force adjustment assembly, the maximum cutting force of the harvester can be adjusted. By using the pull-blade assembly, the serrated cutter and the movable cutter prevent further cutting force from being applied to the tea stems, thereby ensuring that the harvester does not cause continuous damage to the tea stems.

The application discloses an ultrasonic vibration and laser-assisted combined ceramic matrix composite material drilling device and belongs to the field of composite material processing.The device comprises a laser, a main shaft laser channel, a compressed air channel, an optical path adjusting device, an ultrasonic vibration device, a fixing device, a drill bit and the like, wherein the laser is used for emitting laser light, the laser light is incident to the optical path adjusting device through the main shaft laser channel, the optical path adjusting device and the fixing device ensure that two beams of laser light emitted after light splitting are always irradiated by a drill bit through hole on the drill bit, and the function of heating and softening workpiece material is realized; the ultrasonic vibration device makes the end of the drill bit output the main shaft rotation movement and simultaneously output a longitudinal-torsional composite ultrasonic vibration with a certain amplitude, realizes an intermittent contact cutting drilling mode, and reduces cutting force and torque; compressed air blows away cutting chips through the compressed air channel and the drill bit through hole on the drill bit; longitudinal-torsional composite ultrasonic vibration, laser-assisted processing and drilling are organically combined, the damage of the air outlet and inlet is reduced, and the processing quality is improved.
