DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The present utility model will be further illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0023] Embodiment 1: As Figures 1 to 3As shown in the figure, a tube joint boring center flushing device includes a machine tool body 1. A hollow main shaft 101 is provided on the machine tool body 1. A chuck 2 is connected to the front end of the main shaft 101. A lock nut 3 is connected to the rear end of the main shaft 101. A flushing pipe 4 is connected to the lock nut 3. The flushing pipe 4 is located inside the main shaft 101 and extends to the front part of the main shaft 101. A rotary joint 5 is connected to the lock nut 3. A liquid inlet pipe 601 is connected to the rotary joint 5. The liquid inlet pipe 601 is connected to a circulating pump 6. The circulating pump 6 is connected to a coolant tank 8. The coolant tank 8 is located at the bottom of the machine tool body 1.

[0024] The tail of the main shaft 101 is provided with an external thread. The lock nut 3 is in threaded fit with the tail of the main shaft 101. The lock nut 3 is provided with a stepped threaded hole 301.

[0025] One interface of the rotary joint 5 is in threaded fit with one end of the threaded hole 301. The tail end of the flushing pipe 4 is in threaded fit with the other end of the threaded hole 301.

[0026] The front end of the flushing pipe 4 is connected with a conical high-pressure nozzle 401. An oil seal 7 is connected to the rear end of the main shaft 101. The inner ring of the oil seal 7 contacts the outer wall of the flushing pipe 4.

[0027] The top of the coolant tank 8 is open, and a filter screen is connected at the opening.

[0028] The circulating pump 6 is connected to the bottom end of the coolant tank 8 through a liquid suction pipe 602, and a filter element 801 is installed at the joint of the liquid suction pipe 602 and the coolant tank 8.
