The spindle bearings are imported precision spindle bearings, lubricated withprecision requirements of the spindle. The motor directly drives the spindle to rotate through the synchronous belt, and the hydraulic clamp realizes the spindle braking to ensure the indexing accuracy of the spindle C axis.
2.3. upright post
As the main load-bearing structural part of the machine tool, the column adopts a unique honeycomb rib type as a whole, which has stronger load-bearing capacity. When the Y-axis moves, the servo motor drives the lead screw, which is completely perpendicular to the X-axis. The feeding movement of the Y-axis can be realized without interpolation, and the accuracy is better than that of the interpolation
Y-axis. In addition, the Y axis is equipped with a separate locking mechanism, which further improves the rigidity of the machine tool when cutting. 2.4. B axis
The function of axis B is to realize the rotation around the Y axis by the motor installed on the Y axis slide plate, which can stop directionally and interpolate with other axes to realize the functions of drilling oblique holes, milling inclined planes or milling complex curved surfaces. The three-toothed disc structure can ensure good accuracy and rigidity in B-axis machining.
The B-axis system has the characteristics of fast indexing speed, high precision of repeated positioning and large allowable torque, which greatly strengthens the milling ability of this machine tool. The function of axis B is to drive the tool spindle to swing within the range of- 105 ~+ 120. Axis B has the following two working states:
( 1) Drive the tool spindle to index every 7.5 degrees.
Firstly, the positioning and locking cylinder moves to disengage the locking toothed disc, and rotates the B axis to an integer multiple of 7.5. After the cutter reaches the preset position, the positioning and locking cylinder moves to mesh the locking toothed disc with the fixed toothed disc and the moving toothed disc, so that the cutter spindle can be accurately positioned and locked.
(2) Drive the tool spindle to do interpolation.
Firstly, the locking cylinder moves to disengage the locking toothed disc, and the locking cylinder moves at any position to loosen the B-axis, and the B-axis motor drives the tool spindle to swing in the range of- 105 ~+ 120, thus realizing interpolation processing.2.5. Tool spindle
The tool spindle can be equipped with both loading tools and rotating tools, which is a combination of the tool rest of traditional lathe and the spindle of boring and milling machine. The tool spindle is a mechanical spindle with an nterface of CAPTO C5, which can be used for turning, boring, milling and drilling, etc. It is driven by the main motor, and the power is transmitted to the tool spindle through the belt and bevel gear, and its maximum rotation speed can reach 3500r/min. Under the turning condition, the three-tooth disc of the tool spindle is locked ; Under milling conditions, the three-tooth disc of the tool spindle is in a loose state.
2.6. Feed system
The X, Z and W axes are directly driven by the servo motor, and the Y axis is driven by the servo motor through the toothed belt. Among them, the lead screw of X-axis and Y-axis servo motor with brake can't rotate in non-working state.
X, Z and Y axes adopt high-rigidity and high-precision ball linear guides, and all three linear axes are equipped with grating rulers to realize closed-loop position control.
2.7. Second spindle
The auxiliary spindle moves through the servo motor to drive the lead screw to realize programmable control. Through the same transmission configuration as the turning spindle, the synchronous control of the two spindles can be better realized, and the accuracy of front and back machining of parts can be guaranteed.
2.8. Tool magazine and tool changing device
The tool magazine and the tool changing manipulator are designed and manufactured by Taiwan Province Jifu according to the requirements of our factory. The standard configuration is 32 tools, and the servo electric tool changing manipulator is simple and reliable in control. The indexing of tool magazine is driven by servo motor, which makes the rotation stable and fast, and the tool-to-tool change time is 2 seconds. In order to better master the structure and principle of tool changing of tool magazine and tool changing manipulator of this machine tool,lease read the instruction manual of tool magazine and tool changing manipulator carefully and operate according to the requirements in the instruction manual.
