[0021] The present invention has the following beneficial effects:

[0022] 1. The automatic boring equipment of the drilling and milling machining center drives the control rod and the water spray pipe to rotate together through the rotation of the limiting ring, so that the water spray pipe can surround the boring tool with water, which will reduce the temperature of the boring tool and help reduce thermal deformation, so as to relatively maintain the accuracy of the boring tool; the surrounding water spray can more effectively take away the heat generated by the boring tool during the cutting process, thereby reducing the working temperature of the boring tool; the boring tool is prone to wear and damage at high temperature, so lowering the temperature can significantly extend the service life of the boring tool.

[0023] 2. The automatic boring equipment of the drilling and milling machining center drives the water spray pipe to surround the boring cutter to spray water through the limiting ring. As the boring cutter continues to penetrate the workpiece, the control rod is driven to rotate through the cooperation between the transmission gear and the first rack, thereby changing the water spray angle of the water spray pipe, so that the water spray pipe can spray water at the hole of the workpiece, so that as much water as possible can enter the inside of the hole of the workpiece, so that the water can contact with the boring cutter as much as possible, reduce the temperature of the boring cutter, and at the same time, can also wash away the chips and impurities generated in the cutting process to prevent them from accumulating in the cutting area and affecting the cutting effect of the boring cutter;

Under the same water pressure, the water can be sprayed farther by reducing the channel, so that the water flow can contact the boring tool deep in the workpiece, so that the boring tool can be better cooled. The water flow can enter the hole of the workpiece as much as possible, and the hole of the workpiece can be flushed with more water as much as possible, further enabling the boring tool to be effectively cooled during the processing of the workpiece.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

One side of the annular sealing sheet 28 is connected to the water inlet pipe 22. The guide rod 29 is slidably connected to the limiting ring 24. A pair of water inlet holes 4 are opened on the limiting ring 24, and the water inlet holes 4 are connected to the annular water tank 27. The other end of the water inlet hole 4 is fixedly connected to a pipe 43. The square design of the transmission square rod 13 makes it possible for the subsequent limiting ring 24 to not drive the fixed disc 25 to rotate during the rotation process, so that the boring tool 26 on the fixed disc 25 can work normally.

[0041] A first rack 210 is disposed at the other end of the guide rod 29, and a protruding block 211 is disposed at the middle section of the guide rod 29;

[0042] Two pairs of guide plates 3 are fixedly connected to the limiting ring 24, a control rod 33 is rotatably connected between the two guide plates 3, a water spray pipe 310 for spraying water is arranged inside the control rod 33, the limiting ring 24 is rotatably connected to the limiting plate 23, and the limiting plate 23 is slidably connected to the operating table 1;

[0043] A fixed seat 14 is provided at the other end of the operating table 1, and a power motor 15 is installed on the fixed seat 14. The power output end of the power motor 15 is fixedly connected to a three-jaw chuck 16, and the three-jaw chuck 16 is used to fix the workpiece 17. The three-jaw chuck 16 is a prior art, and the specific usage method will not be described in detail. At the same time, professionals in this field can also freely select it according to specific circumstances.

[0044] One end of the guide rod 29 is located between the two guide plates 3, and a sliding column 214 is fixedly connected to one side of the guide rod 29, and the sliding column 214 is slidably connected to the spiral groove 215;

[0045] When the sliding post 214 slides in the spiral groove 215, the restriction ring 24 rotates.

[0046] A mounting plate 2 is provided between the limiting plate 23 and the fixed plate 11. The mounting plate 2 is fixedly mounted on the operating table 1. A rotating ring 21 is rotatably connected to one side of the mounting plate 2 close to the limiting plate 23. One side of the rotating ring 21 is fixedly connected to one end of the guide rod 29. The water inlet pipe 22 is slidably connected to the mounting plate 2. Through the design of the water inlet pipe 22, the water pipe can be connected to the water inlet pipe 22, so that water can enter the annular water tank 27 to provide a water source for the equipment.

[0047] First, the workpiece 17 to be bored is fixed on the three-jaw chuck 16, and the position of the workpiece 17 can be fixed by the three-jaw chuck 16. At the same time, when the subsequent power motor 15 drives the three-jaw chuck 16 to rotate, the three-jaw chuck 16 can drive the workpiece 17 to rotate together to prevent the workpiece 17 from being separated from the fixation of the three-jaw chuck 16; after the position of the workpiece 17 is fixed, the power motor 15 is started to rotate the workpiece 17, so as to facilitate boring the workpiece 17, and then the hydraulic rod 12 is started to drive the transmission square rod 13, the fixed disc 25 and the boring tool 26 to move to the position of the workpiece 17, so that the boring tool 26 bores the workpiece 17;

[0048] The hydraulic rod 12 drives the transmission square rod 13, the fixed disc 25 and the boring tool 26 to move, and at the same time, drives the limiting plate 23, the limiting ring 24 and the fixed disc 25 to slide together. It should be noted that the limiting plate 23, the limiting ring 24 and the fixed disc 25 will not separate. Figure 6 and Figure 7 When the fixed disc 25 slides to the left, the spiral groove 215 is driven to slide together by the sliding of the fixed disc 25, so that the sliding column 214 is guided by the spiral groove 215, so that the sliding column 214 drives the guide rod 29 to rotate. When the guide rod 29 rotates, it drives the rotating ring 21 at one end to rotate together, so that the rotating ring 21 rotates on the mounting plate 2. At the same time, through the rotation of the guide rod 29, a force is applied to the guide plate 3 on one side of the guide rod 29, so that the guide rod 29 drives the guide plate 3 and the limiting ring 24 to rotate together. When the limiting ring 24 rotates, it will drive the control rod 33 to rotate. Through the rotation of the control rod 33, the water spray pipe 310 will rotate around the boring tool 26 to spray water, so that a circle of the boring tool 26 can be sprayed with water; it should be noted that when the limiting ring 24 rotates, it will drive the annular water tank 27 to rotate together. Figure 4 At the same time, the design of the water inlet pipe 22 passing through the mounting plate 2 prevents the annular sealing sheet 28 from rotating, and the annular water tank 27 and the annular sealing sheet 28 from separating.

[0049] In this embodiment: the rotation of the limiting ring 24 drives the control rod 33 and the water spray pipe 310 to rotate together, so that the water spray pipe 310 can spray water around the boring tool 26. The surrounding water spray can more effectively remove the heat generated by the tool during the cutting process, thereby reducing the working temperature of the tool, so that the tool can always work at a lower temperature, the cutting performance is more stable, and it is not easy to passivate or damage the tool. This can reduce the downtime caused by tool problems, thereby improving processing efficiency; at the same time, the surrounding water spray cooling can reduce high-temperature splashing and sparks in the cutting area, thereby reducing the risk of operator injury.

[0050] Embodiment 2: This embodiment is intended to promote the solution of the problem that the control rod 33 cannot drive the water spray pipe 310 to adjust the angle as the boring depth of the workpiece 17 by the boring tool 26 increases. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 12 A transmission gear 34 is provided on the rotating shaft that is rotatably connected to the control rod 33 and the guide plate 3 , and the transmission gear 34 is meshedly connected to the first rack 210 .

[0051] A guiding inclined groove 212 and a guiding straight groove 213 are formed inside the protruding block 211 , and the guiding inclined groove 212 is communicated with the guiding straight groove 213 .

[0052] A blocking plate 41 is slidably connected inside the water inlet 4, a sliding ball 42 is provided on one side of the blocking plate 41, and the sliding ball 42 is slidably connected to the guiding inclined sliding groove 212 and the guiding straight sliding groove 213;

[0053] When the sliding ball 42 is located in the guiding inclined slide groove 212, the blocking plate 41 blocks the water inlet hole 4;

[0054] When the sliding ball 42 is located in the guiding straight sliding groove 213 , the blocking plate 41 opens the water inlet hole 4 .

[0055] The hydraulic rod 12 drives the transmission square rod 13, the fixed disc 25, the limiting plate 23 and the limiting ring 24 to slide, and at the same time, the limiting plate 23, the limiting ring 24 and the fixed disc 25 gradually move away from the mounting plate 2. Figure 7, which will cause the transmission gear 34 on the control rod 33 to mesh with the first rack 210 on the guide rod 29. When the transmission gear 34 slides, it will rotate through cooperation with the first rack 210. When the transmission gear 34 rotates, it will drive the control rod 33 to rotate together, so that the control rod 33 drives the water spray pipe 310 to adjust the angle of water spraying. Because the boring tool 26 has drilled into the interior of the workpiece 17 at this time, the water spray pipe 310 can no longer spray water on the boring tool 26. After adjusting the angle in this way, the water spray pipe 310 will spray water into the holes of the workpiece 17, so that as much water as possible can be sprayed into the holes of the workpiece 17.

[0056] When the limiting ring 24 moves away from the mounting plate 2, it will drive the sliding ball 42 on the sealing plate 41 in the water inlet hole 4 to slide in the guiding inclined groove 212 in the raised block 211, so that the sliding ball 42 can drive the sealing plate 41 to slide downward. Through the downward sliding of the sealing plate 41, the sealing plate 41 opens the water inlet hole 4, so that the water entering the annular water tank 27 through the water inlet pipe 22 can enter the pipe 43 through the water inlet hole 4, thereby opening the water passage and allowing the water to enter the water spray pipe 310. When the sliding ball 42 slides into the guiding straight groove 213, the water inlet hole 4 is now completely opened. Through such a design, the boring tool 26 will start to spray water to cool down the boring tool 26 only when boring the workpiece 17.

[0057] In this embodiment: water is sprayed around the boring tool 26 through the water spray pipe 310, and at the same time, the transmission gear 34 on the control rod 33 is meshed with the first rack 210 during the sliding process of the limiting ring 24, so that the control rod 33 is driven to rotate through the rotation of the transmission gear 34, so that after the boring tool 26 drills into the workpiece 17, the water spray pipe 310 can spray water at the hole of the workpiece 17, so that the water can enter the hole of the workpiece 17, so that the water can contact the boring tool 26, so that the water can effectively absorb and take away the heat generated in the cutting process, reduce the temperature of the boring tool 26 and the workpiece 17, prevent the boring tool 26 from being worn or damaged due to overheating, and prevent the workpiece 17 from affecting the processing accuracy due to thermal deformation. At the same time, the design of water entering the hole of the workpiece 17 can also wash away the chips and impurities generated in the cutting process, and prevent them from accumulating in the cutting area and affecting the cutting effect of the boring tool 26;

[0058] Furthermore, through the design of the sliding ball 42 sliding in the guiding inclined groove 212 and the guiding straight groove 213, the equipment will open the water passage only when the boring tool 26 is cutting and boring the workpiece 17, so that the water can cool down the boring tool 26, and further the boring tool 26 can effectively cool down the boring tool 26 during the process of processing the workpiece 17.

[0059] Embodiment 3: This embodiment is intended to promote the solution of the problem that after the control rod 33 drives the water spray pipe 310 to adjust the angle, the water spray pipe 310 sprays water too close. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 12 An arc-shaped slide groove 31 and an inclined slide groove 32 are provided on one side of the guide plate 3, and the arc-shaped slide groove 31 and the inclined slide groove 32 are connected.

[0060] A sliding plate 36 is slidably connected inside the control rod 33, and a sliding column 35 is fixedly connected to one side of the upper end of the sliding plate 36. The sliding column 35 is slidably connected to the arc-shaped sliding groove 31 and the inclined sliding groove 32;

[0061] When the slide post 35 is located in the inclined slide groove 32 , the slide plate 36 slides in the control rod 33 .

[0062] A control inclined slot 37 is provided at the lower end of the sliding plate 36 , and a second rack 38 is slidably connected in the control inclined slot 37 . The second rack 38 is slidably connected to the inside of the control rod 33 , and a sealing gear 39 is meshedly connected to one side of the second rack 38 .

[0063] A through hole 311 is provided on the sealing gear 39. The through hole 311 is designed to be offset from the center of the sealing gear 39. The through hole 311 is used to connect the pipe 43 and the water spray pipe 310. The sealing gear 39 is rotatably connected to the water spray pipe 310. The through hole 311 is designed to be offset from the center of the sealing gear 39, so that when the sealing gear 39 rotates, the size of the channel between the pipe 43 and the water spray pipe 310 will change.

[0064] The transmission gear 34 drives the control rod 33 to rotate, and at the same time, drives the slide post 35 on the control rod 33 to slide in the arcuate slide groove 31 and the inclined slide groove 32. When the slide post 35 slides from the arcuate slide groove 31 into the inclined slide groove 32, the Fig.10 , which will cause the slide post 35 to slide upward. When the slide post 35 slides upward, it will drive the sliding plate 36 to slide upward. When the sliding plate 36 slides upward, the right end of the second rack 38 will slide in the control inclined slot 37. The second rack 38 will slide to the right through the inclined guide of the control inclined slot 37. The sliding of the second rack 38 to the right will cause the sealing gear 39 to rotate. When the sealing gear 39 rotates, Fig.11 , which causes the through hole 311 to rotate together. The rotation of the through hole 311 changes the size of the passage between the water spray pipe 310 and the pipe 43, so that the water can be sprayed relatively farther, so that as much water as possible can enter the hole of the workpiece 17;

[0065] It should be noted that the sealing gear 39 is located between the water spray pipe 310 and the pipeline 43, and the water spray pipe 310 and the pipeline 43 are rotationally connected with the sealing gear 39 in the middle, and the sealing gear 39 will not be separated from the water spray pipe 310 and the pipeline 43, so that the water passage can be stable.

[0066] In this embodiment, water is sprayed around the boring tool 26 by the water spray pipe 310, and the water spray pipe 310 is driven to rotate by the control rod 33. When the water spray angle of the water spray pipe 310 is adjusted, the slide column 35 on the control rod 33 slides from the arc-shaped slide groove 31 into the inclined slide groove 32, so that the sealing gear 39 rotates, and the passage between the pipeline 43 and the water spray pipe 310 is adjusted, so that the passage between the pipeline 43 and the water spray pipe 310 becomes smaller, so that the water can be sprayed relatively farther. Through such a design, when the boring tool 26 drills deeper into the workpiece 17, the water flow can be sprayed farther to contact the boring tool 26 in the deep part of the workpiece 17, so that the boring tool 26 can be better cooled. At the same time, the water flow can enter the hole of the workpiece 17 as much as possible, and the hole of the workpiece 17 can be washed by more water as much as possible, further enabling the boring tool 26 to be effectively cooled during the process of processing the workpiece 17.

[0068] The above is only a preferred embodiment of the present invention.
