Abstract
A pipe end machining device configured to machine an end of a pipe includes an outer housing having a spindle rotatably mounted therein, tool carriers are mounted on the spindle, a hub assembly attached to the outer housing, a vertical adjustment assembly attached to the hub assembly and to the outer housing, and a drive assembly configured to rotate the spindle and tool carriers. The vertical adjustment assembly adjusts the upward and downward position of the cutting tools relative to the pipe. The hub assembly mounts the device to the pipe and fixes the relative upward or downward position of the cutting tools relative to the pipe, thereby preventing vibration and chatter when the device is cutting a planar surface on the end of the pipe.
Claims18
A pipe end machining device configured to machine an end of a pipe, comprising:
- an outer housing;
- a spindle mounted within the outer housing and configured to carry tool supports and cutting tools, the spindle being rotatable relative to the outer housing;
- a hub assembly mounted within the spindle, the hub assembly including
- a mounting assembly including an upper plate, a lower plate, and three shafts extending between the upper and lower plates, the lower plate configured to be attached to the pipe;
- a stem extending from the upper plate and connected to the outer housing by an interengagement of the stem and the outer housing, the interengagement configured to allow the outer housing and the spindle to move linearly relative to the stem, but preventing rotational movement of the outer housing relative to the stem, and
- a hub mounted on the three shafts and between the upper and lower plates, the hub being movable relative to the three shafts, the hub being connected to the spindle by an interengagement between the hub and the spindle, the interengagement configured to avow the spindle to rotate relative to the hub and move linearly with the hub.
