Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 1 and 2, the utility model discloses a cutter arbor 1, mount pad 2 and tool bit fixing base 4, cutter arbor 1 can be dismantled with mount pad 2 and be connected, tool bit fixing base 4 and 2 swing joint of mount pad. Connecting plate 3 is fixedly connected to mounting seat 2, a plurality of threaded holes are formed in connecting plate 3 at equal intervals, and tool bit fixing seat 4 is connected with connecting plate 3 through first connecting bolt 5. In the use, tool bit fixing base 4 can be connected with the different positions of connecting plate 3 as required to the regulation of 4 positions of tool bit fixing base is realized, and then the regulation of tool bit position on the realization tool bit fixing base 4 satisfies different diameter machining's needs.
One end of being connected with mount pad 2 on cutter arbor 1 is equipped with a plurality of locating pieces 6 that set up along cutter arbor 1 circumference, is equipped with on mount pad 2 and supplies cutter arbor 1 and every locating piece 6 male constant head tank 7, and every locating piece 6 all is connected fixedly with mount pad 2 through second connecting bolt 8. The locating block 6 can play a limiting role in cooperation with the locating groove 7, and circumferential rotation dislocation of the cutter bar 1 and the mounting seat 2 in the machining process is avoided. A plurality of locating pieces 6 are all connected with the mounting base 2 and fixed to achieve effective connection and fixation. The positioning block 6 is connected with the mounting seat 2 through the second connecting bolt 8, the mounting seat 2 can be replaced according to use requirements, and the maintenance cost is reduced.
In this embodiment, four positioning blocks 6 are disposed on the tool bar 1 along the circumferential direction of the tool bar 1, and the four positioning blocks 6 are distributed on the tool bar 1 in a circular array.
