In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
Referring to fig. 1 and 2, a boring cutter mechanism 100 is provided, wherein the boring cutter mechanism 100 is used for machining a chuck of a pipe beveling machine. The boring cutter mechanism 100 comprises a boring cutter bar 10 and a connecting seat 20, wherein a boring cutter 11 is fixedly arranged at one axial end of the boring cutter bar 10, and the boring cutter 11 is used for machining a chuck; the connecting seat 20 is sleeved on the periphery of the boring cutter bar 10 and is circumferentially fixed with the boring cutter bar 10, but can axially slide along the boring cutter bar 10, and the connecting seat 20 is used for fixedly connecting a pipeline beveling machine.
The boring cutter mechanism 100 further includes: a fastener 30 and a swivel sleeve 40. Wherein the fastener 30 is adapted to axially fix the boring bar 10 with the connection block 20; the rotary shaft sleeve 40 and the boring cutter 11 are respectively arranged at two sides of the connecting seat 20, and the rotary shaft sleeve 40 and the boring cutter rod 10 are axially fixed but can rotate around the boring cutter rod 10 in the circumferential direction.
In this embodiment, the connecting seat 20 and the boring bar 10 are circumferentially fixed, and can slide axially along the boring bar 10 as follows: the outer wall of the boring cutter bar 10 is provided with an axially extending chute 10a, the connecting seat 20 is fixedly provided with a sliding block 21 (shown in fig. 3), and the sliding block 21 is arranged in the chute 10a and is adapted to the chute 10a, and can slide along the chute 10a.

It should be noted that only one sliding groove 10a may be provided on the outer wall of the boring bar 10, or a plurality of sliding grooves 10a may be provided which are uniformly distributed in the circumferential direction. When a plurality of sliding grooves 10a are provided, a plurality of sliding blocks 21 uniformly distributed along the circumferential direction need to be arranged on the connecting seat 20, so that the sliding blocks 21 are correspondingly arranged with the sliding grooves 10 a; at this time, the connection holder 20 and the boring bar 10 can be fixed more favorably in the circumferential direction.
Referring to fig. 3, the manner in which the fastener 30 is adapted to axially secure the boring bar 10 to the adapter 20 is as follows: the fastening piece 30 is a locking screw, a threaded hole 20a along the radial direction is formed in the connecting seat 20, and the fastening piece 30 is matched with the threaded hole 20a and can pass through the threaded hole 20a to be abutted against the boring cutter bar 10.
Thus, when the fastener 30 is screwed such that the fastener 20 passes through the threaded hole 20a and abuts against the outer wall of the boring bar 10, the fastener 30 enables axial fixation of the boring bar 10 to the connection seat 20; axial sliding movement of the coupling seat 20 along the boring bar 10 is enabled when the fastener 30 is tightened such that the fastener 20 does not contact the boring bar 10.

The inner ring is fixedly sleeved on the outer peripheral surface of the rotating shaft 41, and the outer ring is fixedly arranged on the inner wall of the groove 10 c.
In this embodiment, the boring tool mechanism 100 further includes a gland 43, and the gland 43 is fixedly disposed at the other end of the boring tool bar 10. The gland 43 can form a non-contact seal with the rotary shaft sleeve 40 or the rotary shaft 41, so as to prevent foreign matters such as external particulate matters from entering the groove 10c, and influence the lubrication effect of the rolling bearing 42, so that the boring bar 10 and the rotary shaft sleeve 40 cannot rotate normally.

The position of the rotary sleeve 40 is not limited to the other axial end of the boring bar 10, and may be provided at other positions of the boring bar 10, but it is desirable that: the connection seat 20 is arranged between the boring cutter 11 and the rotary shaft sleeve 40.
