[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a machining drilling mechanism includes a base, a longitudinal moving unit is installed on the base, the longitudinal moving unit includes a first motor 4, a first screw rod 5, a first mounting plate 6, and two parallel first slide rails 3, the first screw rod 5, the first slide rail 3, and the first motor 4 are all installed on the base, one end of the first screw rod 5 is connected to the output end of the first motor 4, a first screw rod sleeve is fixed to the bottom of the first mounting plate 6, the first screw rod 5 passes through the inside of the first screw rod sleeve, and the first mounting plate 6 is slidably connected to the first slide rail 3. When the first motor 4 rotates, it drives the first screw rod 5 to rotate, and when the first screw rod 5 rotates, it drives the first mounting plate 6 to move along the direction of the first slide rail, thereby realizing the movement of the drill bit in the front and rear directions.

[0022] A lateral moving unit is installed on the upper side of the first mounting plate 6. The lateral moving unit includes a second motor 12, a second mounting plate 13, a second screw, and two second slide rails arranged in parallel. The second motor 12, the second screw, and the second slide rail are all installed on the first mounting plate 6. One end of the second screw is connected to the output end of the second motor 12. The second mounting plate 13 is slidably connected to the second slide rail. A second screw sleeve is fixed to the bottom of the second mounting plate 13, and the second screw passes through the inside of the second screw sleeve. The working principle is the same as that of the longitudinal moving unit. When the second motor 12 rotates, it drives the second mounting plate 13 to move along the second slide rail. The first slide rail is perpendicular to the second slide rail, so as to realize the left and right movement of the drill bit.

[0023] A vertical moving unit is installed on the upper side of the second mounting plate 13, and the vertical moving unit includes a third motor 14, a third screw rod 15, a third mounting plate 7, and a bracket 1. The bracket 1 is fixed on the second mounting plate 13, and the third motor 14 and two third slide rails parallel to each other are fixedly installed on the bracket 1. The output shaft of the third motor 14 is connected to the third screw rod 15, and the third mounting plate 7 is slidably connected to the third slide rail. A third screw rod sleeve is fixedly installed on the third mounting plate 7, and the third screw rod sleeve is sleeved on the outside of the third screw rod 15. The working principle is the same as that of the longitudinal moving unit. When the third motor 14 rotates, it drives the third mounting plate 7 to move along the direction of the third slide rail. The third slide rail is perpendicular to the first slide rail and the second slide rail, so as to realize the up and down movement of the drill bit.

[0024] Two drill bit mounting shafts 8 are vertically penetrated on the third mounting plate 7, and the drill bit is installed at the end of the drill bit mounting shaft 8, and the drill bit mounting shaft 8 is rotatably connected to the third mounting plate 7. The two drill bit mounting shafts 8 are located on both sides of the transmission shaft 9, and the two drill bit mounting shafts 8 are arranged in parallel with the transmission shaft 9, and the two drill bit mounting shafts 8 and the transmission shaft 9 are perpendicular to the third mounting plate 7. The spindle motor 2 and the transmission assembly are installed on the third mounting plate 7, and further, the spindle motor 2 is fixedly installed on the pulley protection frame 19. The transmission assembly is transmission-connected with the drill bit mounting shaft 8 and the output end of the spindle motor 2. Specifically, the transmission assembly includes a transmission shaft 9, and a shaft sleeve 18 is penetrated and fixed on the third mounting plate 7, and the transmission shaft 9 is penetrated and installed inside the shaft sleeve 18, and the transmission shaft 9 is rotatably connected to the shaft sleeve 18. A motor mounting plate 16 is fixedly installed at one end of the shaft sleeve 18, and further, a pulley protection frame 19 that penetrates up and down is fixedly installed on the motor mounting plate 16, and specifically, the spindle motor 2 is fixedly installed on the pulley protection frame 19. A first pulley is installed at one end of the transmission shaft 9, and a second pulley is installed on the output shaft of the spindle motor 2. The second pulley is located in the pulley protection frame 19, and a belt is connected between the first pulley and the second pulley. When the spindle motor 2 rotates, the transmission shaft 9 is driven to rotate through the first pulley, the second pulley, and the belt. A first gear is installed on the transmission shaft 9, and a second gear is installed on both drill bit mounting shafts 8. A transmission gear 17 is meshed between the first gear and the second gear, and the transmission gear 17 is rotatably installed on the third mounting plate 7. A gear protection box 21 is fixed on the third mounting plate 7, and the first gear, the second gear, and the transmission gear 17 are all located in the gear protection box 21. When the transmission shaft 9 rotates, the first gear rotates, and the second gear is driven to rotate through the two transmission gears 17, thereby driving the two drill bit mounting shafts 8 to rotate in the same direction, thereby causing the drill bit to rotate rapidly.

[0025] The third mounting plate 7 is provided with a broken knife detection assembly, which includes a fourth mounting plate 10, a cylinder 11, a cover plate 20, and a fourth slide rail. The fourth slide rail and the cylinder 11 are both mounted on the fourth mounting plate 10. The fourth mounting plate 10 is slidably connected to the fourth slide rail. The fourth slide rail is parallel to the third slide rail. The fourth mounting plate 10 is connected to the movable shaft end of the cylinder 11. A sensor is mounted on the cover plate 20. The sensor is located above the drill bit mounting shaft 8 and directly above the drill bit. The cylinder 11 can push the cover plate 20 and the sensor to move along the fourth slide rail, thereby changing the distance between the sensor and the drill bit, making it easy to adjust the distance, thereby realizing fixed-distance detection. When the drill bit breaks, the state of the sensor changes, thereby feeding back the signal and informing the operator through an alarm device or other warning device to ensure safe operation.

[0026] Working principle: When the first motor 4 rotates, the first mounting plate 6 and the mounting components on the first mounting plate 6 are moved forward and backward; when the second motor 12 rotates, the second mounting plate 13 and the mounting components thereon are moved left and right; when the third motor 14 rotates, the third mounting plate 7 and the mounting components thereon are moved up and down. The third mounting plate 7 is equipped with a spindle motor 2, a transmission assembly, and a broken knife detection assembly, that is, when the third mounting plate 7 moves, the spindle motor 2, the transmission assembly, and the broken knife detection assembly all move synchronously. When the spindle motor 2 rotates, the transmission shaft 9 is driven to rotate through the first pulley, the second pulley, and the belt. When the transmission shaft 9 rotates, the first gear rotates synchronously, and the second gear is driven to rotate through the two transmission gears 17, thereby driving the two drill bit mounting shafts 8 to rotate in the same direction, thereby causing the drill bit to rotate rapidly. Therefore, the drill bit of the utility model can realize electric movement in three dimensions, with a simple structure and convenient operation.
