Technical Field

[0001] This utility model relates to the field of turning and milling technology, and in particular to a CNC eight-station five-axis turning and milling machining center. Background Technology

[0002] A mortise and tenon machine is a machine tool specifically designed for machining mortises (i.e., square holes). It is a specialized piece of equipment for creating traditional mortise and tenon structures (such as mortises), typically using a hollow chisel fitted over a drill bit. The drill bit first rotates to cut a round hole, and then the chisel moves downwards to shape the round hole into a square one. Mortise and tenon machines also use chain cutting or CNC machining.

[0003] In the existing technology, the tenoning machine has a simple structure and limited functions. It can only perform simple punching work and has low working efficiency, making it difficult to meet the needs of industrial production. Utility Model Content

The clamping assembly contains a B-axis workpiece rotation axis capable of 360° rotation. The turret mounting base is equipped with a working assembly for mounting different tools. The working assembly contains an A-axis turret fixedly mounted on the turret mounting base. A gantry is mounted on the base.

[0006] As a further description of the above technical solution: the clamping assembly includes a B-axis motor fixedly installed in the ejector pin holder, and a clamping ejector pin rotatably installed on the ejector pin holder. The ejector pin holder is fixedly installed on the station clamping ejector pin table, and the output shaft of the B-axis motor can drive the clamping ejector pin to rotate synchronously.

[0007] As a further description of the above technical solution: the working component includes a high-speed electric spindle rotatably mounted on the A-axis turret, and an A-axis motor fixedly mounted on the A-axis turret, wherein the A-axis motor can drive the high-speed electric spindle to rotate synchronously.

[0008] As a further description of the above technical solution: a workbench is provided on the workbench, a guide rail is provided on the workbench, and the station clamping ejector pin table and ejector pin fixing seat are both slidably connected to the guide rail.

[0009] As a further description of the above technical solution: a fixed frame that is fixedly connected to the turret mounting base is slidably installed on the gantry frame; a first motor and a third motor are provided on the gantry frame; a second motor is provided on the base; lead screws are fixedly installed at the output ends of the first motor, the second motor, and the third motor; the three lead screws are threadedly connected to the worktable and the fixed frame respectively; wherein the first motor and the third motor are threadedly connected to the fixed frame.

The four sides of the A-axis turret can simultaneously install 32 different types of tools, supporting the completion of turning, milling and drilling operations in one clamping, enriching the functionality of the device and greatly improving the applicability of the device. A large amount of debris is generated during workpiece processing. The debris falls onto the conveyor belt through the feed port. The conveyor belt drives the debris removal and dust collection machine interface. The dust collection machine interface is connected to a dust collector to absorb the debris and ensure a clean environment during the processing. The first and third motors drive the fixed frame to move up and down and left and right via lead screws, while the second motor drives the worktable to move back and forth via lead screws.
