Description

Technical Field

[0001] The utility model relates to the technical field of milling cutter clamps, in particular to a clamp which is convenient for replacing a milling cutter. Background Art

[0002] A milling cutter is a rotating tool with one or more teeth used for milling. When working, each tooth cuts off the workpiece's excess in sequence and intermittently. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines. The basic requirements for the cutting part of the milling cutter include high hardness and wear resistance to ensure that it has sufficient hardness to cut into the workpiece at room temperature and extend its service life. After long-term use, the milling cutter usually needs to be replaced.

[0003] When installing and disassembling the milling cutter, bolts are usually used for installation and disassembly. This requires that when the milling cutter needs to be replaced later, tools are needed to install and disassemble the bolts before the milling cutter can be replaced. This makes the replacement process more cumbersome and also requires designated tools to replace the milling cutter, which is inconvenient to use. Utility Model Content

When the milling cutter needs to be disassembled, the sliding post 11 drives the mounting post 14 to move, so that the mounting post 14 leaves the inner wall of the mounting groove 8, and the bidirectional threaded rod 2 drives the two sets of clamps 7 to move in opposite directions, so as to loosen the clamping and fixing of the milling cutter, and then disassemble the milling cutter, achieving the purpose of facilitating the installation and disassembly of the milling cutter. During the installation and disassembly process, no tools are required, which facilitates the subsequent replacement of the milling cutter. The structure is simple and easy to use. By removing the second bolt 18, inserting the new positioning block 6 into the inner wall of the positioning groove 5, and then fixing it with the second bolt 18, the clamping plate 7 can be replaced.
