Description

Hybrid Machine Tool with Parallel Heads

technical field

The invention relates to a mechanical processing device, in particular to a hybrid machine tool for realizing five-axis processing.

Background technique

Multi-axis linkage CNC machining is the most difficult and widely used technology in CNC technology. It is applied to the efficient, precise and automatic processing of complex curved surfaces. Critical processing equipment that is urgently needed. Internationally, multi-axis linkage numerical control technology is regarded as a symbol of a country's industrialization level.

In the current multi-axis linkage machine tool, the structure of the rotating part of the tool mostly adopts a series structure, which has the disadvantage of weak structural rigidity.

Contents of the invention

The purpose of the present invention is to overcome the above defects, design and develop a hybrid machine tool with large working space, good rigidity, and easy control of parallel cutter heads.

The technical solution of the present invention is: a hybrid machine tool with parallel cutting heads, including a machine frame composed of a machine base, a column, and a beam. It is characterized in that a horizontal slide table that can move horizontally along the X axis is installed on the bed base. A rotary table that can generate Z-axis rotation is installed on the top, a vertical slide table that can move horizontally along the Y-axis is installed on the beam, and a tool rest that can move vertically along the Z-axis is installed on the vertical slide table. Motor and left bevel gear, left motor drives and connects left bevel gear, and right motor and tie rod are installed on the right side of tool post, right motor drives and connects tie rod, is installed and connected planetary gear and cutting tool on the tie rod, and planetary gear meshes with left bevel gear.

The left and right sides of the tool holder are also provided with left and right reducers respectively, the left reducer is arranged between the left motor and the left conical gear, the left motor is driven and connected to the left bevel gear through the left reducer, and the right reducer is set Between the right motor and the tie rod, the right motor drives the connection tie rod through the right reducer.

A right bevel gear is also installed on the right side of the tool rest, and the right bevel gear meshes with the planetary gear.

The motion principle of the present invention is as follows: the horizontal sliding table can move horizontally in the X-axis on the machine tool base, the rotary table can drive the workpiece to rotate in the Z-axis on the horizontal sliding table, and the tool rest moves with the vertical movement on the vertical sliding table. The sliding table can produce Y-axis movement and Z-axis vertical movement. The left motor on the left side of the tool post drives the left bevel gear and planetary gear through the left reducer. The right motor on the right side of the tool post drives the tie rod through the right reducer. The planetary gear and the left cone The gears mesh, and the tie rod drives the planetary gear to swing around the Y axis and rotate around the _Z1 axis, thereby driving the tool to swing around the Y axis and rotate around the _Z1 axis, which can realize the machining of the pentahedron of the workpiece.

The invention has reasonable and simple structure, easy manufacture and low cost. Realize the parallel movement of tool spindle rotation and spindle swing, the machine tool tool has a large rotation angle, a large working space, and a small structure occupation space, which is conducive to real-time control and improves the efficiency of the machine tool.

Detailed ways

As shown in Figure 1, the horizontal sliding table 3 is installed on the machine tool base 1, and generates horizontal movement of the X-axis; the rotary table 2 is installed on the horizontal sliding table 3, and generates Z-axis rotation; the column 4 is installed on the machine tool base 1 Above; the beam 5 is installed on the column 4; the vertical sliding table 9 is installed on the beam 5, and produces the horizontal movement of the Y axis; the tool holder 10 is installed on the vertical sliding table 9, and produces the vertical movement of the Z axis; the left motor 6 1. The left reducer 7 is installed on the left side of the knife rest 10, and drives the left bevel gear 8 to move; the right motor 13, the right reducer 12 are installed on the right side of the knife rest 10, and drives the tie rod 14 to swing around the Y axis; the tie rod 14 The planetary gear 15 is installed on the top, the planetary gear 15 meshes with the left bevel gear 8, the cutter 16 is installed on the planetary gear 15, the left bevel gear 8 drives the planetary gear 15 to rotate, and the tie rod 14 drives the planetary gear 15 to swing around the Y axis and around the _Z1 axis Rotate, thereby driving cutter 16 to swing around the Y axis and rotate around the _Z1 axis. The left speed reducer 7 increases the driving torque of the left motor 6, and the right speed reducer 12 increases the driving torque of the right motor 13. Right bevel gear 11 is installed on the right side of tool rest 10, and right bevel gear 11 meshes with planetary gear 15 and increases the supporting rigidity of planetary gear 15.

Coordinate axis establishment: the axis of the planetary gear 15 is the _Z1 axis, the axis of the left bevel gear 8 is the _Y1 axis, _and the _X1 axis is determined according to the right-hand rule. At zero time, the coordinates _{X1Y1Z1 coincide} with the coordinates XYZ.
