Description

Technical Field

[0001] The utility model belongs to the technical field of slotting machines, and in particular relates to an adjustable metal plate slotting mechanism. Background Art

[0002] A slotting machine, also known as a slotting milling machine, is a machine used to manufacture machines. It is usually called a machine tool or a machine tool, and is usually referred to as a machine tool. It is mainly used to process internal grooves and grooves of metal materials. The working principle is to move the cutter wheel through a rotating milling cutter to cut the metal workpiece to achieve the purpose of processing the internal groove or groove.

[0003] After searching, a Chinese patent for a tool holder adjustment mechanism of a CNC slotting machine, such as the authorization announcement CN 217192869 U, is found. The patent comprises a U-shaped tool holder, in which a plurality of tool seats are arranged. By rotating and adjusting the plurality of tool seats and installing four tool heads of different sizes on the same tool holder, the tool head required can be selected for slotting processing, and thus there is no need to repeatedly disassemble and replace tool heads of different models and sizes. The operation is convenient, time-saving and labor-saving, and work efficiency is improved. By adjusting and fixing the spacing between the plurality of tool seats, the spacing between the plurality of grooves opened on the material plate can be changed. The patent has good applicability and solves the problem that when the tool holder of the existing CNC slotting machine is used, it is inconvenient to open grooves of different models and sizes according to needs, and the tool heads of different models and sizes need to be replaced to open grooves of different models and sizes, which is cumbersome to operate, and it is inconvenient to adjust the spacing between the plurality of tool seats, and the spacing between the plurality of opened grooves cannot be changed.

[0004] The above process of releasing the tool holder is not efficient. Each time, a wrench needs to be used to unscrew multiple locking bolts from the corresponding positioning grooves one by one to complete the release of the tool holder, and then push the tool holder to slide horizontally on the horizontal axis. The operation steps are relatively cumbersome, which reduces the adjustment efficiency of the tool holder spacing and increases the labor intensity of the operator. Utility Model Content
