Detailed Description
The structure and the working principle of the present invention are further explained by the following specific embodiments and the attached drawings:
the large-diameter cutter head 100 with the PU mirror surface comprises a spindle connecting seat 18, wherein the central axis of the spindle connecting seat 18 is connected with a matched pull rod 19 and a spindle hole (not shown in the figure) of an external machining center through a connected BT40 spindle handle 11; in particular, the spindle connecting seat 18 is connected with a BT40 spindle shank 11 through a pair of end face keys 9 and 10.
The BT40 spindle shank 11 matched with the pull rod 19 is installed in a spindle hole (not shown in the figure) of an external machining center, is tensioned by tensioning the pull rod 19 through a pneumatic device (not shown in the figure), and is driven by an external machine tool (not shown in the figure) to rotate the integral cutter head 100 by driving the spindle connecting seat 18 to rotate.
The other side of the main shaft connecting seat 18 is provided with a pair of tool apron 5 and 6 symmetrically arranged on an eye main shaft 18a, and the tool apron 5 and 6 are connected with the main shaft connecting seat 18 through tool apron connecting shafts 7 and 8;
specifically, the tool apron connecting shafts 7 and 8 are mounted on the spindle connecting base 18 through M6 × 45 socket head cap screws 14, 15, 16 and 17, and M4 × 20 positioning screws 25, 26, 27 and 28 (see fig. 5-1, 5-2 and 5-3) for adjusting and positioning are further mounted on the tool apron connecting shafts 7 and 8.
The tool apron 5, 6 is mounted on the tool apron connecting shaft 7, 8 through M6 × 30 hexagon socket head cap fixing screws 29, 30, and the tool apron 5, 6 is also mounted with M4 × 8 positioning screws 21, 22, 23, 24 for adjusting positioning (see fig. 2-1, 2-2, 2-3).
