Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in figure 1, the inner wall grinding mechanism of the pipe die comprises a base 1, a headstock 2, a trolley 3, a grinding mechanism 4, an axial driving device and at least one bracket 5. The head frame 2 and the carriage 5 are both mounted on top of the base 1.
A chuck 21 is mounted on one side of the head frame 2 close to the bracket 5, the chuck 21 is fixedly connected with one end of the pipe die 6 coaxially, and a rotation driving mechanism (not shown in the figure) is further mounted on the head frame 2, connected with one end of the chuck 21 and drives the chuck 21 to rotate, so as to drive the pipe die 6 to rotate. 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, and the rollers 52 are slidably and rollably engaged with the side walls of the pipe die 6 for supporting the pipe die 6 and keeping the axis line of the pipe die 6 horizontal. The rollers 52 are symmetrically arranged on both sides of the central axis of the bracket base 51, and position the axis of the pipe die 6 right above the central axis of the bracket base 51.
