The lathe head 1, the carriage 5 and the tailstock 3 are mounted in a straight line on top of the base, and the carriage 5 is mounted in turn between the lathe head 1 and the tailstock 3.
A chuck 21 is rotatably arranged at one side of the lathe head 2 close to the tailstock 3, and the chuck 21 is used for fastening one end of the pipe die 8. As shown in FIG. 3, the bracket 5 comprises a bracket seat 51 and two rollers 52 rotatably mounted on the top of the bracket seat 51, the rollers 52 are rotatably fitted with the side walls of the pipe die 8, the rollers 52 are symmetrically mounted on both sides of the central axis of the bracket seat 51, and the axial line of the pipe die 8 is positioned right above the central axis of the bracket seat 51. The lathe head 2 is also provided with a rotary driving mechanism (not shown in the figure), and the rotary driving mechanism is connected with the chuck 21 and drives the chuck 21 to rotate, so that the pipe die 8 is driven to rotate.
One end of the boring bar 4 is coaxially mounted on the inner hole of the spindle of the chuck 21 through a bearing 22, so that the rotation of the chuck 21 does not drive the boring bar 4 to rotate. And the other end of the boring bar 4 is connected to the tailstock 3, and the lathe head 2 and the tailstock 3 respectively fix two ends of the boring bar 4 to prevent the boring bar 4 from bending.
As shown in fig. 2, the tail seat 3 comprises a lower tail seat 31 and an upper tail seat 32, the lower tail seat 31 is fixedly installed on the base 1, the upper tail seat 32 is detachably installed on the top of the lower tail seat 31 through bolts, and the pipe die 8 can be conveniently installed and detached by detaching the upper tail seat 32. Two clamping grooves 311 are formed in the top of the lower tailstock 31, and the two clamping grooves 311 extend along the axial direction of the boring bar 4. The bottom surface of the upper tailstock 32 is provided with two clamping strips 321 which are in one-to-one correspondence with the two clamping grooves 311 and are matched with the two clamping grooves 311, and the two clamping strips 321 are respectively inserted into the corresponding clamping grooves 311, so that the lower tailstock 32 can be conveniently installed, and the position of the upper tailstock 32 can be finely adjusted, so that the upper tailstock 32 compresses the boring bar 4.

Then the chuck 21 drives the pipe die 8 to rotate through the rotary driving mechanism, and the boring cutter 7 is driven to move through the sliding driving mechanism, so that the inner wall of the pipe die 8 can be bored.
According to the invention, the two ends of the boring rod 4 are supported by the lathe head 2 and the tailstock 3, so that the bending of the boring rod 4 is reduced, and the inner wall of the bored pipe die 8 is more uniform. And if the boring bar 4 is rotated, when the boring cutter 7 is positioned above, the boring cutter 7 sinks under the action of gravity to reduce the boring radius, when the boring cutter 7 is positioned below, the boring cutter 7 sinks under the action of gravity to increase the boring radius, and the bottom thickness of the bored pipe die 8 is smaller than the top thickness. Therefore, the invention adopts the mode that the pipe die 8 rotates and the boring rod 4 does not rotate, so as to ensure that the boring radius is not changed, thereby ensuring that the top and the bottom of the bored pipe die 8 have uniform thickness.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
