The cutter buckle 105 can be used for placing a plurality of cutters with different specifications, and different cutters can be automatically replaced according to different machining requirements during machining; the tool setting gauge 112 can calibrate the coordinate value of the tool before feeding when the tool is replaced, so that the collision accident between the tool and the workpiece is avoided.

Referring to fig. 4, in some embodiments, a tow chain frame 14 for placing a tow chain or an air pipe is further disposed on the top end of the spindle device 8; a grating ruler 13 for measuring the moving distance in the X-axis direction, the Z-axis direction and the Y-axis direction is arranged on the cross beam 3, the supporting carriage frame 12 and the base 1

When the machining device is used specifically, a workpiece to be machined is placed on the machining table 4, the machining table 4 is driven to move back and forth in a reciprocating mode along the Y-axis direction through the Y-axis driving device 6, the main shaft device 8 is driven to move left and right in a reciprocating mode along the X-axis direction through the X-axis driving device 5, and the main shaft device 8 is driven to move up and down in a reciprocating mode along the Z-axis direction through the Z-axis driving device 7 to machine the workpiece; when the three-axis direction is not enough for processing, the processing angle can be adjusted through the B-axis rotating device 43 and the C-axis rotating device 44, the B-axis rotating device 43 can drive the C-axis rotating device 44 to rotate, so that the workpiece is driven to rotate, and the C-axis rotating device 44 can directly drive the workpiece to rotate, so that the processing angle can be adjusted according to the processing requirement; when a tool needs to be replaced, the X-axis driving device 5 drives the spindle device 8 to move to the upper side of the tool magazine 10, the tool magazine 10 can rotate the tool which needs to be used to the position right below the spindle 83 according to requirements, so that the spindle 83 can replace the tool, after the spindle 83 replaces the tool, coordinate values before tool feeding are adjusted through tool setting of the tool setting gauge 112, and the tool is placed to collide with a workpiece in the moving process.

The base 1 is made of advanced marble materials, so that the damping vibration attenuation performance, the low thermal expansion coefficient, the long-term precision stability and the high corrosion resistance are excellent, and the performance and the stability of the whole machine are far higher than those of a base part material and the machine tool base still adopts a traditional cast iron structure; the X-axis driving device 5, the Y-axis driving device 6 and the Z-axis driving device 7 are all driven by linear motors, and in the machining process, the friction force generated by the X, Y, Z-axis direction movement is small, the thermal elongation phenomenon of a lead screw in the traditional transmission mode is avoided, and the advantages of small inertia, no reverse gap, high response speed and high movement speed are achieved; the spindle motor 82 and the spindle 83 of the spindle device 8 are synchronous motor spindles, so that excessive heat is not generated during processing, and the spindle device has the advantages of small heat productivity and large torque output; by arranging the balance device 9 on the main shaft device 8, when the main shaft device 8 loses lifting power, the balance cylinders 93 arranged at two sides of the main shaft device 8 can support the whole main shaft device 8, so that the main shaft device 8 is prevented from slipping off when no power is supplied, the main shaft 83 is prevented from being damaged, and the stability is improved; through set up the grating chi 13 that is used for surveing X axle direction, Z axle direction and Y axle direction displacement distance on crossbeam 3, support carriage frame 12 and base 1, the distance of calculation displacement that can be accurate improves the machining precision.
