[0028] In use, the driving mechanism 2 drives the transmission shaft 103 to rotate, and then drives the pneumatic three-jaw chuck 102 to rotate, thereby providing the necessary rotating movement for the turning tool 101 to process the workpiece. In the feeding and discharging assembly 3, the hopper 301 is used to store the workpiece to be processed, the elevator 302 lifts the workpiece in the hopper 301 to the storage inclined plate 303, the workpiece slides down the storage inclined plate 303 to the feeding port of the transmission shaft 103, at this time, the first electric push rod 305 pushes the push rod 306 to send the workpiece into the pneumatic three-jaw chuck 102 for clamping.

[0029] In this embodiment, the lathe body 1 is fixedly provided with a mounting frame 304, and the storage inclined plate 303 and the first electric push rod 305 are fixedly installed on the mounting frame 304. The mounting frame 304 provides a fixed support for the storage inclined plate 303 and the first electric push rod 305, ensures the stability of their positions during work, and ensures that the workpiece can accurately slide down from the storage inclined plate 303 to the feeding port of the transmission shaft 103, and the first electric push rod 305 can accurately push the push rod 306 to send the workpiece into the chuck.

[0030] Further, the lower end of the storage inclined plate 303 is V-shaped. Through this arrangement, the workpiece is accurately positioned coaxially with the transmission shaft 103, facilitating the first electric push rod 305 to smoothly send the workpiece into the pneumatic three-jaw chuck 102 through the push rod 306.

[0031] In this embodiment, the storage inclined plate 303 is fixedly provided with a guide plate 307. Through this arrangement, the workpiece can be guided to slide down on the storage inclined plate 303 according to a predetermined path, preventing the workpiece from deviating or falling during the sliding process, and ensuring that the workpiece can accurately reach the feeding port of the transmission shaft 103.

[0032] In this embodiment, the driving mechanism 2 includes a first synchronous wheel 201, a second synchronous wheel 202 and a driving motor 204, the first synchronous wheel 201 is fixedly sleeved on the end of the transmission shaft 103 away from the three-jaw chuck 102, the driving motor 204 is fixedly installed on the lathe body 1, the second synchronous wheel 202 is fixedly installed on the rotating shaft of the driving motor 204, and the first synchronous wheel 201 and the second synchronous wheel 202 are drivingly connected through a synchronous belt 203.

[0033] In use, after the driving motor 204 is started, it drives the second synchronous wheel 202 to rotate, and then transmits power to the first synchronous wheel 201 through the synchronous belt 203, thereby rotating the transmission shaft 103, and finally rotating the pneumatic three-jaw chuck 102 to provide power for processing the workpiece.

[0034] In this embodiment, the material blocking assembly 4 is arranged on the side of the lathe body 1 away from the feeding and discharging assembly 3. The material blocking assembly 4 comprises a second electric push rod 401 fixed on the lathe body 1. The piston rod end of the second electric push rod 401 is fixedly connected with a blocking block 402 after sliding into the inside of the lathe body 1.

[0035] After the workpiece is sent into the pneumatic three-jaw chuck 102, the second electric push rod 401 pushes the blocking block 402 to extend and block the other end of the workpiece to prevent the workpiece from extending too long.

[0036] In this embodiment, the inside lower end of the lathe body 1 is fixedly installed with a discharging guide plate 5 below the three-jaw chuck 102.

[0037] When the pneumatic three-jaw chuck 102 loosens the processed workpiece, the workpiece falls onto the discharging guide plate 5, which guides the workpiece to slide to the designated collection position, realizing automatic discharging.

[0038] Further, the inside of the discharging guide plate 5 is fixedly bonded with a noise reduction rubber pad. The noise reduction rubber pad can reduce the noise generated when the workpiece falls onto the discharging guide plate 5, and also can reduce the collision between the workpiece and the discharging guide plate 5, playing a buffering protection role and prolonging the service life of the discharging guide plate 5.

[0039] Working principle:

[0040] The workpiece to be processed is stored in the hopper 301. The elevator 302 lifts the workpiece from the hopper 301 to the storage inclined plate 303. The workpiece is positioned at the V-shaped position at the lower end of the storage inclined plate 303 under the guidance of the guide plate 307. The first electric push rod 305 pushes the push rod 306 to send the workpiece into the pneumatic three-jaw chuck 102 through the transmission shaft 103. At the same time, the second electric push rod 401 pushes the blocking block 402 to extend and block the other end of the workpiece. Then the three-jaw chuck 102 clamps, and then the second electric push rod 401 retracts the blocking block 402. The driving motor 204 drives the first synchronous pulley 201 and the transmission shaft 103 to rotate through the synchronous belt 203, so that the pneumatic three-jaw chuck 102 drives the workpiece to rotate, and the lathe tool 101 processes the workpiece. After processing, the pneumatic three-jaw chuck 102 loosens the workpiece. The piston rod of the first electric push rod 305 continues to extend to push the workpiece on the three-jaw chuck 102 out, and the workpiece falls onto the discharging guide plate 5. At the same time, the piston rod of the first electric push rod 305 retracts. The cycle is repeated to realize the automatic feeding and discharging and processing of the lathe.
