As a further scheme of the invention, the rotating column 14 is arranged on a rotating disc 41 externally connected with a power supply, and the rotating disc 41 is rotatably arranged on the lower pressing seat 13; an offset groove 42 is formed in the rotating disc 41 along the radial direction of the rotating disc 41, the rotating column 14 is fixedly arranged on a sliding block 43, the sliding block 43 is slidably arranged in the offset groove 42, a horizontally arranged adjusting screw 44 is connected to the sliding block 43, the adjusting screw 44 is in threaded connection with the offset groove 42, and the adjusting screw 44 drives the sliding block 43 to slide in the offset groove 42.

Because the size of the inner hole of the workpiece to be machined is not fixed, the position of the threaded cutter 12 needs to be adjusted, so that the invention can be suitable for workpieces with different sizes and the applicability is improved. Therefore, as shown in fig. 7, the present invention has a radially disposed offset groove 42 formed in the rotary disk 41, and the rotary post 14 slides in the offset groove 42 via the slide block 43. It is noted that when machining a workpiece, it is necessary to place the inner hole of the workpiece concentrically with the rotary disk 41 before machining. In operation, the adjusting screw 44 is rotated to drive the sliding block 43 to slide in the offset slot 42, so as to adjust the rotating column 14 to a proper position, thereby facilitating subsequent thread machining. The method is simple to operate, so that the method can be suitable for workpieces with different sizes, and the applicability of the method is improved.

As a further aspect of the present invention, a clamping mechanism is provided on the table 11, and the clamping mechanism is used for driving the clamping mechanism to clamp the workpiece when the pressing base 13 is pressed downwards.

As a further aspect of the present invention, the clamping mechanism includes two clamping jaws 51 rotatably mounted on the worktable 11, the two clamping jaws 51 are respectively disposed at both sides of the workpiece, and a return spring 52 is disposed between the two clamping jaws 51; the side of the clamping claws 51 far away from the workpiece is provided with arc-shaped convex parts 53, the arc-shaped convex parts 53 are slidably provided with a driving ring 54, the driving ring 54 is used for driving the two clamping claws 51 to approach each other, the driving ring 54 is vertically slidably arranged on the workbench 11, and the driving plates 55 are arranged on two sides of the driving ring 54.

The invention needs to clamp the workpiece to be machined firstly during thread machining, and the common clamping mode is to horizontally apply clamping force from the circumferential direction of the workpiece. However, because the thread machining needs to be performed along the axial direction of the inner hole of the workpiece, i.e. the vertical direction shown in fig. 6, the workpiece may shake vertically during the machining process by using a common clamping manner, which affects the machining precision. As shown in fig. 1 and 6, the clamping mode of the present invention is that the lower pressing base 13 drives the cutter to move downwards, and the guiding column 61 is arranged to make the moving direction of the lower pressing base 13 vertically downwards. The guide post 61 presses the pressing plate 63 below by the pressing block as the pressing base moves down, and the pressing plate 63 drives the driving plate 55 to move vertically downward by the pressing spring. The driving plate 55 is fixedly connected with the driving ring 54, so that the driving ring 54 moves vertically downwards, the arc-shaped convex parts 53 on the clamping claws 51 slide, and the two clamping claws 51 are driven to approach each other to clamp the workpiece between the two clamping claws 51, thereby realizing the fixation of the workpiece. As shown in fig. 6, since the clamping jaw 51 is rotatably mounted on the worktable 11, and the rotating point is located at the lower part of the clamping jaw 51, not only the clamping force in the horizontal direction is provided when the clamping jaw 51 clamps, but also the workpiece is clamped in the vertical direction together with the rigid conveyor belt 71, and the positioning of the workpiece is completed. The return spring 52 is provided in the present invention to release the clamping force of the clamping claws 51 by the restoring force of the return spring 52 and drive the drive ring 54 to be restored when the lower holder 13 is restored. The compression spring 64 of the present invention is provided to accommodate different sizes of workpieces. Because the downward moving distance of the lower pressing seat 13 is fixed, but the rotating angles of the clamping claws 51 required by different workpieces are different, the clamping claws 51 can clamp workpieces with different sizes through the arrangement of the compression springs 64. The clamping rotary device can clamp workpieces with different sizes by utilizing the downward movement of the downward pressing seat 13, can provide clamping force in the horizontal direction and the vertical direction for the workpieces, and realizes the positioning of the workpieces, and the positioning is accurate.
