Description

Technical Field

[0001] The utility model relates to the technical field of composite tool bars, in particular to a composite tool bar for thread processing. Background Art

[0002] A compound tool bar consists of a tool holder, a movable tool arm, and a fixed tool arm. Compared to a screw-type tool bar, a compound tool bar has a more complex structure. The movable tool arm and the fixed tool arm combine to form a cutter head to achieve multifunctional processing. Because the structural design and processing requirements of compound tool bars are more complex, they are more suitable for complex processing operations than screw-type tool bars. Since the tool bar fixing method and the angle of the movable tool arm are connected through this interface, and the movable tool arm is replaced alternately, tool changing is more complicated. Some high-end compound tool bars are equipped with an automatic tool changing function, which greatly reduces the burden on operators and improves production efficiency. Compound tool bars are relatively expensive, but because their composite structure can effectively improve processing efficiency and quality, they are widely used in the field of high-precision processing.

[0003] However, the cutter head and the shank of the existing composite cutter bar are inconvenient to disassemble and replace.

[0004] Therefore, a composite tool bar for thread processing is needed to improve the above problems. Utility Model Content
