Description

Technical Field

[0001] This utility model relates to the field of die casting processing technology, specifically to a multi-axis milling machine. Background Technology

[0002] Die casting is a process in which molten copper, zinc, aluminum, or aluminum alloy is poured into a die casting machine equipped with a casting mold. The die casting machine then casts parts of copper, zinc, aluminum, or aluminum alloy into shapes and sizes limited by the mold. During the die casting process, due to factors such as the impact of casting pressure, insufficient clamping force of the equipment, and mold precision, defects such as burrs and flash may occur on the surface of the die casting. Therefore, in order to ensure that the surface of the die casting is smooth and flat for subsequent processing and manufacturing, it is necessary to process the surface of the die casting using milling equipment.

[0003] For example, Chinese patent document CN117680747A discloses a steel plate milling device, including a sliding mechanism, a milling mechanism, and a mounting platform. The sliding mechanism is connected to the milling mechanism through the mounting platform. The sliding mechanism has the function of driving the milling mechanism to move linearly back and forth along the direction to be milled on the steel plate. The milling mechanism includes a drive system and a milling cutter disc. The drive system drives the milling cutter disc to rotate.

[0004] As can be seen from the above disclosure, the milling cutter head is driven to rotate at high speed by the drive system. After the milling cutter head comes into contact with the surface of the die-cast part, the defects on the surface of the die-cast part can be processed.

[0005] However, in actual use, it was found that different cutting heads need to be used depending on the type of defect when processing the surface of die-cast parts. The above technical solution is a single-axis cutting head structure, so the corresponding cutting head needs to be changed frequently when processing different types of defects, which affects the overall milling efficiency. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-axis milling machine that can quickly switch between different types of defects by pre-installing multiple sets of cutters, thereby reducing downtime and improving the overall milling efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-axis milling machine, including a machine base, an installation platform on the machine base, a rotary table connected to the installation platform, the rotary table rotating with the connection point with the installation platform as the rotation center, the rotary table being used to connect and clamp tooling for die castings, a longitudinal horizontal moving device connected below the installation platform for driving the installation platform to perform longitudinal horizontal feed, a transverse horizontal moving device provided above the installation platform, a vertical moving device connected to the transverse horizontal moving device, and a cutting tool device connected to the vertical moving device for driving the cutting tool device to perform vertical feed, the cutting tool device including a first cutting head group, a second cutting head group, and a tool changing mechanism, the tool changing mechanism for driving the second cutting head group to feed relative to the first cutting head group, so that the second cutting head group and the first cutting head group are staggered.

[0008] The present invention is further configured such that: the longitudinal horizontal moving device includes a longitudinal horizontal lead screw and a longitudinal horizontal drive motor rotatably connected, the longitudinal horizontal drive motor is used to drive the longitudinal horizontal lead screw to rotate, the bottom of the mounting platform is provided with a first connecting part, the first connecting part is fitted around the outer periphery of the longitudinal horizontal lead screw and can form a threaded engagement with the longitudinal horizontal lead screw, the longitudinal horizontal lead screw is provided with longitudinal horizontal slide rails on both sides, the bottom of the mounting platform is fixed with a longitudinal horizontal slider, the longitudinal horizontal slider is coupled to the longitudinal horizontal slide rails and forms a sliding engagement between the two.

[0009] The present invention is further configured such that: the transverse horizontal moving device includes a transverse horizontal lead screw and a transverse horizontal drive motor rotatably connected, the transverse horizontal drive motor is used to drive the transverse horizontal lead screw to rotate, transverse horizontal slide rails are provided on both sides of the transverse horizontal lead screw, a transverse horizontal slider is coupled on the transverse horizontal slide rail and can form a sliding fit with the transverse horizontal slide rail, a connecting platform is fixed on the side of the transverse horizontal slider facing away from the transverse horizontal slide rail, and a second connecting part is provided on the inner side of the connecting platform, which is fitted onto the outer periphery of the transverse horizontal lead screw and forms a threaded fit.

[0010] The present invention is further configured such that: the vertical moving device includes a vertical drive motor; a vertical lead screw is rotatably connected to the outside of the connecting platform; the vertical drive motor is used to drive the vertical lead screw to rotate; vertical slide rails are provided on both sides of the vertical lead screw; a vertical slider is coupled on the vertical slide rail and can form a sliding fit with the vertical slide rail; a fixed platform is fixed on the side of the vertical slider facing away from the vertical slide rail; a third connecting part is provided on the inner side of the fixed platform, which is fitted onto the outer periphery of the vertical lead screw and forms a threaded fit.

[0011] The present invention is further configured such that: the tool changing mechanism includes a cylinder, the cylinder is fixed to the outside of the fixed platform, the output end of the cylinder is fixed to a frame, the second tool head assembly is fixed to the outside of the frame, the inner side of the frame is fixed to a tool changing slide rail, the outer side of the fixed platform is fixed to a tool changing slider, and the tool changing slider can be coupled with the tool changing slide rail to form a sliding fit between the two.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Since the tooling device includes a first tool head group, a second tool head group, and a tool changing mechanism, the tool changing mechanism can drive the second tool head group to feed relative to the first tool head group, so that the second tool head group and the first tool head group are staggered. This allows the first tool head group to contact the die casting surface alone or the second tool head group to contact the die casting surface alone, thus achieving direct and rapid switching of tool heads. Therefore, it effectively solves the technical problem of long time required for tool head replacement in the prior art. Furthermore, by pre-installing multiple sets of tool heads, it is possible to quickly switch when dealing with different types of defects, reduce downtime, and improve the overall milling efficiency.
