[0026] See also Figure 1-4 As shown, this embodiment is a new type of five-axis vertical machining center, including:

[0027] A base 1, an upper end of one side of the base 1 is fixedly connected with a saddle 2, and an upper end of the saddle 2 is fixedly connected with a five-axis base plate 3, and an upper end of the five-axis base plate 3 is fixedly connected with a five-axis turntable 6, and the five-axis turntable 6 includes an A-axis base 7, an RV reducer 8, an A-axis flange 9, a bridge plate 12, a servo motor 13, and a hydraulic quartering table 14;

[0028] The base 1 is a mounting carrier of the machining center and provides a supporting and stabilizing force by contacting with the contact surface. The saddle 2 fixes the five-axis base plate 3 and further fixes the five-axis turntable 6, and the five-axis turntable 6 is used to complete the processing of the frame;

[0029] The A-axis base 7 is fixedly connected to one side of the upper end of the five-axis bottom plate 3, and the RV reducer 8 is fixedly connected to the middle of the A-axis base 7, the middle of one end of the RV reducer 8 is fixedly connected to a servo motor 13, and the output end of the RV reducer 8 is fixedly connected to the A-axis flange 9, one end of the A-axis flange 9 is fixedly connected to a bridge plate 12, and a hydraulic quarter-divided table 14 is fixed to the middle of the upper end of the bridge plate 12, and a workpiece 15 is buckled and positioned at the upper end of the hydraulic quarter-divided table 14;

[0030] The A-axis base 7 is used to install the RV reducer 8, and then the servo motor 13 is installed. The servo motor 13 provides the force required for rotation, and the RV reducer 8 is used to reduce the speed. The A-axis flange 9 is connected to the bridge plate 12 and transmits the force generated by the servo motor 13. The hydraulic quartering table 14 is installed through the bridge plate 12, and the hydraulic quartering table 14 is used to place the workpiece 15 to be processed;

[0031] A disc tailstock 10 is fixedly connected to the other side of the upper end of the five-axis base plate 3, and a tailstock flange 11 is fixedly connected to the middle of the disc tailstock 10, and one end of the tailstock flange 11 is fixed to the other end of the bridge plate 12;

[0032] The disc tailstock 10 is structurally mounted on the tailstock flange 11, and the bridge plate 12 is fixed by the tailstock flange 11. The internal bearing of the disc tailstock 10 is used for connection with the tailstock flange 11, which can meet the rotation requirements and reduce the friction generated by the rotation.

[0033] A column 4 is fixedly connected to the middle of the upper end of the base 1, and a spindle box 5 is fixedly connected to the middle of the upper end of the column 4;

[0034] The column 4 is used to install the spindle box 5. The spindle box 5 is a key component of the machining center. It is mainly responsible for supporting the spindle and rotating it, and realizing the functions of starting, braking, speed change and reversing the spindle.

[0035] A bottom end of one side of the base 1 is fixedly connected to a bottom frame 16, and a rotating motor 17 is fixedly connected to one side of the top end of the bottom frame 16. A ball screw 18 is fixed to the output end of the rotating motor 17, and the upper part of the movable end of the ball screw 18 is fixed to the middle part of the lower end of the saddle 2;

[0036] The base frame 16 is used to install the rotating motor 17 and provide a supporting and stabilizing force. The rotating motor 17 provides the force required for the ball screw 18 to rotate. The ball screw 18 is used to convert the curved motion into a linear motion, and the five-axis turntable 6 can be moved in a linear horizontal position.

[0039] The bracket 19 is set to be trapezoidal, and the middle part of one side of the bracket 19 is set to be a cavity;

[0040] The trapezoidal shape meets the installation requirements, and the opening of the cavity is conducive to weight reduction;

[0041] Working principle: After the workpiece 15 to be processed is buckled and positioned on the upper end of the hydraulic quarter-divided table 14, when the hydraulic quarter-divided table 14 is horizontal, that is, when it is at an angle of 0° with the A axis, the top surface of the frame can be processed. When the controlled servo motor 13 applies a rotational force and rotates the hydraulic quarter-divided table 14 to 90°, 180°, and 270°, the surrounding surfaces of the frame can be processed;

[0042] This solution can reduce the cost of use compared to the use of a five-axis machining center while meeting the requirements of multi-sided machining of the frame. The heightened setting of the column 4 is adopted to meet the height of the machining space after the five-axis turntable 6 is installed, meeting the machining requirements, and increasing the distance from the spindle mounting hole to the Z-axis line rail. When machining frame parts around, that is, when the A axis is 90°, there is still sufficient machining space to meet the use requirements and improve the use effect.
