[0024] See also Figure 1-3 As shown, this embodiment is a vertical double-head machining center, comprising:

[0025] A base 1, a column 4 is fixedly connected to one side of the upper end of the base 1, and a left spindle box 5 is arranged at one end of the upper part of one side of the column 4, and a right spindle box 6 is arranged at the other end of the upper part of one side of the column 4, and a left tool magazine 9 and a right tool magazine 10 are fixedly connected to the middle of one side of the left spindle box 5 and the right spindle box 6, respectively, and a left spindle 7 and a right spindle 8 are protruded from the middle of the lower end of the left spindle box 5 and the right spindle box 6, and the left spindle 7 and the right spindle 8 are fixed to the input ends of the left tool magazine 9 and the right tool magazine 10 respectively;

[0026] The base 1 is a mounting carrier and provides a stabilizing force by contacting with the contact surface. The column 4 is used to install the structure of the left spindle box 5 and the right spindle box 6, and then to install the structure of the left tool magazine 9 and the right tool magazine 10. When the left spindle 7 and the right spindle 8 are used to transmit the force, the left spindle box 5 and the right spindle box 6 can drive the left tool magazine 9 and the right tool magazine 10 to rotate, brake, change speed and reverse, so as to process the first workpiece 16 and the second workpiece 17. The operation of the left spindle box 5 and the right spindle box 6 is the existing open technology of the vertical machining center.

[0027] The upper part of the left tool magazine 9 and the right tool magazine 10 are respectively fixedly connected with a left broken tool detection sensor 11 and a right broken tool detection sensor 12, and the lower part of the left tool magazine 9 and the right tool magazine 10 are respectively fixedly connected with a left probe 13 and a right probe 14;

[0028] The left and right broken tool detection sensors 11 and 12 adopt the contact detection principle. When the contact contacts the tool, a force is applied. When the tool is broken or damaged, the contact is not applied with a force and an alarm is issued, thereby achieving the purpose of monitoring the tool breakage. The left and right probes 13 and 14 use visual sensors to monitor the processing of the first workpiece 16 and the second workpiece 17, thereby ensuring smooth processing.

[0029] A saddle 2 is slidably connected to the middle of the upper end of the base 1, and a workbench 3 is fixedly connected to the middle of the upper end of the saddle 2. The upper ends of the workbench 3 are respectively placed with a first workpiece 16 and a second workpiece 17;

[0030] The saddle 2 fixes the workbench 3, and the workbench 3 is used to buckle and position the first workpiece 16 and the second workpiece 17;

[0031] A servo motor 18 is fixedly connected to the top end of one side of the column 4, and a ball screw 19 is fixed to the output end of the servo motor 18. The front of the movable end of the ball screw 19 is fixed to the middle of the back of the left spindle box 5 and the right spindle box 6;

[0032] The servo motor 18 is installed on the ball screw 19 and provides the power required for rotation. The ball screw 19 is used to convert the curvilinear rotation force into linear motion, and the left spindle box 5 and the right spindle box 6 can be adjusted up and down to meet the processing requirements;

[0033] A bracket 20 is fixedly connected to the bottom end of one side of the column 4, and a shaft seat 21 is fixedly connected to the middle of the front of the bracket 20, and one end of the ball screw 19 is sleeved and extends out of the middle of the shaft seat 21;

[0034] The bracket 20 is installed on the shaft seat 21, and the shaft seat 21 is used to support the ball screw 19 and reduce the friction generated by the rotation;

[0035] The front side of the base 1 is threadedly connected with a sheet metal shell 15, and the sheet metal shell 15 covers the base 1, the saddle 2, the left spindle box 5, the right spindle box 6, the left tool magazine 9, and the right tool magazine 10;

[0036] The sheet metal shell 15 provides external shielding and protection for the internal structure of the vertical machining center;

[0037] Working principle: After placing the first workpiece 16 and the second workpiece 17 to be processed on the upper end of the workbench 3, and using the buckle groove on the upper end of the workbench 3 to cooperate with the convex column on the lower end of the first workpiece 16 and the second workpiece 17 to position and fix them;

[0038] At this time, the controlled servo motor 18 applies a rotational force to the ball screw 19, so that the left spindle box 5 and the right spindle box 6 are moved downward, and during the downward movement, the controlled left spindle box 5 and the right spindle box 6 can respectively rotate the left tool magazine 9 and the right tool magazine 10 through the left spindle 7 and the right spindle 8, and the internal tools of the left tool magazine 9 and the right tool magazine 10 act on the first workpiece 16 and the second workpiece 17 to complete the processing operation;

[0039] During the processing of the first workpiece 16 and the second workpiece 17, the left tool breakage detection sensor 11 and the right tool breakage detection sensor 12 adopt the contact detection principle. When the contact contacts the tool, a force is applied. When the tool is broken or damaged, the contact is not applied with a force and an alarm is issued, thereby achieving the purpose of monitoring the tool breakage. The left probe 13 and the right probe 14 use visual sensors to monitor the processing of the first workpiece 16 and the second workpiece 17, thereby ensuring smooth processing.

[0040] Compared with the use of two vertical machining centers, this solution reduces space occupancy on the one hand, and helps to improve operating efficiency and facilitate use on the other hand.
