Large-diameter cutter head fixing frame

Abstract

The invention provides a large-diameter cutter head fixing frame which comprises a supporting base, a locking mechanism used for clamping a cutter head and a limiting base. The supporting base is of an I-shaped structure, the upper working surface of the supporting base is provided with a locating hole and a threaded hole, and the locating hole and the threaded hole can be used for fixing the locking mechanism and the limiting base respectively. A cutter head shaft support is connected onto the limiting base through a fastener. The cutter head shaft support is parallel to the locking mechanism in position, and the height of the supporting working surface of the cutter head shaft support is the same as that of a clamping opening of the locking mechanism. The locking mechanism is arranged on the supporting base in a threaded connection or joggled joint mode. Through the way, according to the large-diameter cutter head fixing frame, a butterfly nut locking mode is adopted in the locking mechanism of the large-diameter cutter head fixing frame so that the cutter head can be assembled and disassembled flexibly; the cutter head shaft support can be used for supporting the cutter head, and the height of the cutter head shaft support can be adjusted according to actual requirements, so that the working height of the cutter head is guaranteed. Meanwhile, a locking frame can be replaced according to different sizes of cutter heads, the large-diameter cutter head fixing frame is flexible and convenient to use, and the working efficiency can be improved effectively.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing and processing, in particular to a large-diameter cutter head fixing frame. Background technique [0002] In the machining process, the machine tool, as the main processing equipment, plays an irreplaceable role. Machine tools rely on the working movement of the tool to cut the material, and the fixed structure of the tool can support the tool and place it in a suitable working position. In the existing technology, the method of fixing the tool spindle is often used to fix the tool; for example, adding a brake device to the tool spindle, or using a pin key to fix the spindle, these methods require special processing of the tool spindle, and the processing technology is complicated , the manufacturing cost is also high, and at the same time, the flexibility is reduced, making disassembly more troublesome. Contents of the invention [0003] The technical problem mainly solved by the pre...
