Description

  The present invention belongs to a chain tool magazine technology of a kind of processing machine. Specifically, the tool guide mechanism of a chain tool magazine in which the axis when the tool holder is in the tool change position is parallel to the axis of the processing spindle. The present invention relates to a structure that can save tool change time and simplify a tool changer.

  The CNC processing machine is provided with a tool change tool magazine, and various different types of cutting tools are attached. One end of the cutting tool has a handle, which can be inserted into the tool holder. It is attached to the transmission mechanism of the magazine, and is driven by the transmission mechanism to reach the tool replacement position in order, and is used for tool replacement by the tool replacement mechanism. Among them, the tool holder is positioned by the positioning device in the transmission mechanism, and is moved by being driven by the transmission mechanism. In the chain type tool magazine, the transmission mechanism is a chain sprocket set, and a tool holder is attached to the chain by a positioning device, and the tool holder is driven by the chain to move. However, the structure of the traditional chain positioning device is relatively complex and not very easy to manufacture, the manufacturing and assembly costs are greatly increased, and the tool changer arm system is also that of the traditional chain positioning device. It is necessary to adapt to the structure, and therefore the manufacturing cost of the tool changing arm system is also increased.

  In order to solve such a problem, for example, Patent Document 1 is provided to solve the problem and inconvenience of a complicated structure. However, regardless of whether the traditional positioning device or the above-mentioned positioning device is adopted for the chain type tool magazine, the tool holder of the tool magazine and the axis of the processing spindle are almost vertical in consideration of the space operation of the entire processing machine. Therefore, in the design of the tool changer, the tool handle is first extracted from the tool holder by moving forward, backward, etc., then the angle is changed and further rotated to rotate the tool holder of the machining spindle. Must be inserted inside. This increases the number of operation steps of the tool changer, wastes tool change time, affects machining efficiency, complicates its structure, increases manufacturing and assembly costs, and causes repairs at the time of damage. The rate also increases.

  In other words, if the tool magazine and the tool spindle of the machining spindle are designed to be parallel, the tool changer can complete the tool change operation only by moving forward and backward, rotating, etc., effectively simplifying the tool change flow Can save tool change time and reduce manufacturing and repair costs.

  Therefore, in the present invention, it is necessary to examine the inconvenience at the time of tool change of the above-mentioned tool magazine, to actively explore the solution path, and to change the angle of the tool changer of the existing chain type tool magazine. A tool guide mechanism of a kind of chain type tool magazine that overcomes certain problems and inconveniences is provided.
