Description

Technical Field

[0001] The present invention relates to the technical field of boring machines, and particularly to a double-axis self-cleaning horizontal boring machine. Background Art

[0002] Boring refers to the further processing of forged, cast or drilled holes. Boring can enlarge the hole diameter, improve the precision, reduce the surface roughness, and can also better correct the deflection of the original hole axis.

[0003] Currently, during the boring process, especially for the processing of deep holes or high-precision holes, chip removal and tool cleaning have always been key problems that plague the processing quality and efficiency. When a traditional single-axis horizontal boring machine is in processing, poor chip removal is likely to cause chip accumulation, scratch the machined hole wall, affect the surface roughness and dimensional accuracy. In addition, during the long-term cutting process of the tool, a large amount of chips and cutting fluid residues will adhere to it. If not cleaned in time, it will affect the cutting performance of the tool and shorten the tool life. In addition, for the processing of some double holes or multiple holes with coaxiality requirements, the single-axis boring machine needs to be positioned and processed multiple times, and the cumulative error is relatively large, making it difficult to meet the high-precision requirements.

[0020] The present invention has the following beneficial effects:

[0021] 1. By providing a boring mechanism and a cleaning mechanism, during the boring process, coolant is pumped in through the liquid injection pipe. The coolant can not only cool the shaft and the boring tool, but also flush out the debris in the boring hole, thereby preventing the debris from accumulating in the boring hole and scratching the inner wall of the processed boring hole.

[0022] 2. Since the boring tool is in contact with the inner wall of the boring hole, during the boring process, there may be debris stuck between the boring tool and the inner wall of the boring hole.

[0024] 4. By providing a tool washing mechanism, after the boring is completed, the hydraulic cylinder contracts to drive the boring tool to reset and retract. When the boring tool moves into the annular seat and contacts the friction head, friction is generated between the friction head and the surface of the boring tool, which can clean the debris adhered to the surface of the boring tool. And the boring tool will drive the sliding plug to reciprocate and seal through the push rod. At this time, the coolant in the recycling box will be pumped into the pump liquid cavity through the one-way liquid inlet pipe, then the coolant in the pump liquid cavity will enter the cylindrical cavity through the one-way liquid outlet hole, and finally the coolant will be sprayed out through the communication groove to wash the surface of the boring tool, further enhancing the cleaning effect on the boring tool.

[0025] 5. By setting up a detection mechanism, the surface of the boring tool can be detected before boring. If the warning light keeps flashing at the same frequency, the boring tool is intact. If the flashing frequency of the warning light is irregular, there is a defect on the surface of the boring tool, and the boring tool needs to be replaced immediately to avoid the boring tool with surface defects affecting the boring quality.

[0035] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following detailed description of the specific embodiments of the present invention will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0036] Refer to Figure 1 - Figure 8 , a double-axis self-cleaning horizontal boring machine, including a machine body 1, and a processing platform 2 is fixedly connected to the inner wall of the machine body 1 through a plurality of fixed shafts;

[0037] Two fixed seats 41 are symmetrically and fixedly connected to the upper end of the processing platform 2. Two electric push rods 42 are symmetrically and fixedly connected to the side walls of the two fixed seats 41. The movable ends of the electric push rods 42 penetrate through the inner walls of the fixed seats 41 and are fixedly connected to clamping plates 43;

[0038] A boring mechanism, the boring mechanism includes a chute 3 opened at the upper end of the processing platform 2. An installation seat 4 is slidably connected to the inner wall of the chute 3. Two hollow boring shafts 5 are rotatably connected to the side wall of the installation seat 4. Two sliding rods 6 are symmetrically and slidably connected to the side wall of the hollow boring shaft 5. Two boring cutters 7 are fixedly connected to the side walls of the two sliding rods 6. A first spring 8 is sleeved on the side wall of the sliding rod 6. The two ends of the first spring 8 are respectively fixedly connected to the boring cutter 7 and the side wall of the hollow boring shaft 5;

[0039] A hydraulic cylinder 40 is fixedly connected to the side wall of the processing platform 2. The movable end of the hydraulic cylinder 40 penetrates through the inner wall of the chute 3 and is fixedly connected to the installation seat 4;

[0040] It should be noted that the hydraulic cylinder 40 can be connected to an external control device. When boring, the hydraulic cylinder 40 is controlled to advance intermittently through an external control program to ensure the boring quality, which is a prior art.

[0041] Cleaning mechanism, the cleaning mechanism includes two rotary joints 9 fixedly connected to the side wall of the mounting seat 4 by fixing axes symmetrically. One end of two hollow boring shafts 5 penetrates through the side wall of the mounting seat 4 and is fixedly connected to the two rotary joints 9 respectively. A liquid injection pipe 10 is fixedly connected to the side wall of the rotary joint 9, and the other end of the liquid injection pipe 10 is connected to an external pump body. An installation ring 11 is fixedly connected to the inner wall of the hollow boring shaft 5. Two cavities 12 are symmetrically arranged in the installation ring 11. The inner walls of the two cavities 12 are both slidably connected with P-shaped blocks 13. One end of the sliding rod 6 extends into the cavity 12 and slidably abuts against the side wall of the P-shaped block 13. A connecting rod 14 is fixedly connected to the side wall of the P-shaped block 13. One end of the connecting rod 14 penetrates through the side wall of the installation ring 11 and is fixedly connected to a sealing plate 15. A second spring 16 is sleeved on the side wall of the connecting rod 14. The two ends of the second spring 16 are respectively fixedly connected to the inner wall of the cavity 12 and the side wall of the P-shaped block 13;

[0042] A driving mechanism is installed on the mounting seat 4, and a flow rate regulating mechanism is installed on the hollow boring shaft 5.

[0043] The flow rate regulating mechanism includes an adjusting plate 17 sealingly and slidably connected to the side wall of the hollow boring shaft 5. The side wall of the adjusting plate 17 is processed with rounded corners. One end of the adjusting plate 17 extends into the hollow boring shaft 5. Two third springs 18 are symmetrically and fixedly connected to the side wall of the hollow boring shaft 5. The other ends of the two third springs 18 are both fixedly connected to the adjusting plate 17. A cam 22 cooperating with the adjusting plate 17 is fixedly connected to the side wall of the mounting seat 4 through a fixed shaft.

[0044] The driving mechanism includes a motor 19 fixedly connected to the side wall of the mounting seat 4 through a bracket. The output end of the motor 19 penetrates through the cam 22 and the side wall of the mounting seat 4 and is fixedly connected to a first gear 20. Second gears 21 are fixedly connected to the side walls of the two hollow boring shafts 5. Each second gear 21 is meshed with the first gear 20.

[0045] Furthermore, when boring a hole, drive the motor 19 and start the external pump body at the same time. Inject coolant into the hollow boring shaft 5 through the liquid injection pipe 10. The coolant flows in the hollow boring shaft 5 and will impact the sealing plate 15, causing the sealing plate 15 to move leftward to the maximum position (as shown in the attachment Figure 5 ), and then the coolant will rush out through the gap between the sealing plate 15 and the installation ring 11 and then into the bored hole of the shaft processing. The coolant can not only cool the shaft and the boring tool 7, but also flush out the debris in the bored hole, thus avoiding the accumulation of debris in the bored hole and causing scratches on the inner wall of the bored hole.

[0046] It should be noted that after the boring is completed, stop pumping the coolant. The sealing plate 15 will reset under the action of the second spring 16 and form a seal with the installation ring 11 again, thereby preventing the mixture of coolant and debris in the bored hole from flowing back into the hollow boring shaft 5.

[0047] It is worth mentioning that since the boring tool 7 fits against the inner wall of the bored hole, during the boring process, there may be debris stuck between the boring tool 7 and the inner wall of the bored hole. At this time, simply using coolant to flush the bored hole may not be able to wash out the stuck debris, and thus there may be an incomplete cleaning situation. Therefore, during the rotation of the hollow boring shaft 5, it will drive the adjusting plate 17 to rotate together. When the adjusting plate 17 rotates to abut against the cam 22, it will push the adjusting plate 17 to move inward into the hollow boring shaft 5, thereby reducing the amount of coolant entering the hollow boring shaft 5. When the adjusting plate 17 separates from the cam 22, the adjusting plate 17 will reset under the action of the third spring 18. At this time, the amount of coolant entering the hollow boring shaft 5 will increase. Therefore, during the boring process, the amount of coolant entering the hollow boring shaft 5 will alternately increase and decrease. Therefore, the impact force exerted by the coolant on the sealing plate 15 will also alternately increase and decrease. Then, in cooperation with the second spring 16, the sealing plate 15 will drive the P-shaped block 13 to slide reciprocally through the connecting rod 14. When the protruding part of the P-shaped block 13 moves to abut against the slide rod 6, the boring tool 7 will move outward a certain distance. When the concave part of the P-shaped block 13 moves into contact with the slide rod 6, the boring tool 7 will move inward. Therefore, during the boring process, the boring tool 7 will reciprocally move, thereby preventing debris from being stuck between the boring tool 7 and the inner wall of the bored hole, and thus enhancing the cleaning effect.

[0048] Two recycling bins 23 are symmetrically and fixedly connected to the lower end of the processing platform 2. The upper ends of the two recycling bins 23 penetrate through the upper end of the processing platform 2. A filter screen 24 is fixedly connected to the inner wall of the recycling bin 23.

[0049] Furthermore, the flushed coolant will eventually fall into the recycling bin 23, and the debris in the coolant will be intercepted by the filter screen 24. Subsequently, the debris on the filter screen 24 can be recycled.

[0050] A tool washing mechanism is installed on the processing platform 2. The tool washing mechanism includes two annular seats 25 symmetrically and fixedly connected to the upper end of the processing platform 2 through a fixed axis. Two sliding cylinders 26 are symmetrically and fixedly connected to the side wall of the annular seat 25. The inner walls of the two sliding cylinders 26 are hermetically and slidably connected with sliding plugs 27. The sliding plug 27 divides the inside of the sliding cylinder 26 into two parts, namely a liquid pumping chamber 271 and a gas pumping chamber 272. A push rod 28 is fixedly connected to the side wall of the sliding plug 27. One end of the push rod 28 penetrates through the inner wall of the annular seat 25 and is fixedly connected with a friction head 29.

[0051] The tool washing mechanism further includes a cylindrical cavity 30 formed in the push rod 28. A communication groove 31 is formed in the friction head 29. One end of the communication groove 31 communicates with the cylindrical cavity 30. The sliding plug 27 and the inner wall of the sliding cylinder 26 are fixedly connected together with a fourth spring 32. The liquid pumping cavity 271 communicates with the recovery tank 23 through a one-way liquid inlet pipe 33. The one-way liquid inlet pipe 33 only allows the coolant in the recovery tank 23 to enter the liquid pumping cavity 271. A plurality of one-way liquid outlet holes 34 are formed in the inner wall of the cylindrical cavity 30. The one-way liquid outlet holes 34 only allow the coolant in the liquid pumping cavity 271 to enter the cylindrical cavity 30.

[0052] Further, after the boring operation is completed, the hydraulic cylinder 40 contracts, driving the boring tool 7 to retract. When the boring tool 7 moves into the annular seat 25 and contacts the friction head 29, friction is generated between the friction head 29 and the surface of the boring tool 7, which can clean the debris adhered to the surface of the boring tool 7. Moreover, the boring tool 7 drives the sliding plug 27 to reciprocate and slide in a sealed manner through the push rod 28. At this time, the coolant in the recovery tank 23 is pumped into the liquid pumping cavity 271 through the one-way liquid inlet pipe 33. Then, the coolant in the liquid pumping cavity 271 enters the cylindrical cavity 30 through the one-way liquid outlet holes 34. Finally, the coolant sprays out through the communication groove 31 to wash the surface of the boring tool 7, further enhancing the cleaning effect on the boring tool 7.

[0053] A detection mechanism is installed on the mounting seat 4. The detection mechanism includes two boxes 35 symmetrically and fixedly connected to the upper end of the mounting seat 4. A conductive sliding plate 36 is slidably connected in the box 35 in a sealed manner. The box 35 communicates with the air pumping cavity 272 through a communication pipe 39.

[0054] The detection mechanism further includes a warning light 38 fixedly connected to the upper end of the box 35. A conductive plate 37 is embedded in the inner wall of the box 35. The conductive sliding plate 36, the conductive plate 37, the warning light 38 and an external power supply are electrically connected through wires.

[0055] Further, the hydraulic cylinder 40 drives the mounting seat 4 to slide on the inner wall of the chute 3, driving the hollow boring shaft 5 to move, so that the boring tool 7 slowly enters the annular seat 25. When the boring tool 7 rotates and contacts the friction heads 29 on both sides, it will squeeze the friction heads 29 to both sides, thereby driving the push rod 28 to move, and then pushing the sliding plug 27 to move. At this time, the air in the air pumping chamber 272 will enter the box body 35 through the connecting pipe 39, pushing the conductive sliding plate 36 to move. When the sliding plug 27 moves to the maximum distance, the air pumped into the box body 35 just pushes the conductive sliding plate 36 to separate from the conductive plate 37. At this time, the warning light 38 goes out. This process repeats. If there is no defect on the surface of the boring tool 7, the amount of air entering the box body 35 each time is the same, and the position where the conductive sliding plate 36 moves is the same, so that the warning light 38 can maintain the same frequency of going out and lighting up. When there is a defect on a certain part of the surface of the boring tool 7, when the defective part squeezes the friction head 29 to drive the sliding plug 27 to move, the moving distance of the sliding plug 27 will become shorter, and thus the amount of air entering the box body 35 will decrease. At this time, the moving distance of the conductive sliding plate 36 decreases, and the conductive sliding plate 36 cannot separate from the conductive plate 37. At this time, the warning light 38 will not go out. Therefore, the staff can observe the flashing frequency of the warning light 38 to determine whether there is a defect on the surface of the boring tool 7. If the warning light 38 keeps flashing at the same frequency, the boring tool 7 is intact. If the flashing frequency of the warning light 38 is irregular, there is a defect on the surface of the boring tool 7, and the boring tool 7 needs to be replaced immediately to avoid the boring tool 7 with a defective surface affecting the boring quality.

[0056] In the present invention, first, the shaft to be bored is placed between two clamping plates 43. Then, the electric push rod 42 is driven to extend, driving the two clamping plates 43 to approach each other, clamping and fixing the shaft to be processed. Next, the motor 19 is started and the hydraulic cylinder 40 is driven to extend synchronously. The motor 19 drives the first gear 20 to rotate, which in turn drives the second gear 21 to rotate, thereby driving the hollow boring shaft 5 to rotate and driving the boring tool 7 to rotate. The hydraulic cylinder 40 drives the mounting seat 4 to slide on the inner wall of the chute 3, driving the hollow boring shaft 5 to move, so that the boring tool 7 slowly enters the annular seat 25. When the boring tool 7 contacts the friction heads 29 on both sides during rotation, it will squeeze the friction heads 29 to both sides, which in turn drives the push rod 28 to move, and then pushes the sliding plug 27 to move. At this time, the air in the air pumping chamber 272 will enter the box body 35 through the connecting pipe 39, pushing the conductive slide plate 36 to move. When the sliding plug 27 moves to the maximum distance, the air pumped into the box body 35 just pushes the conductive slide plate 36 to separate from the conductive plate 37. At this time, the warning light 38 goes out. This process is repeated. If there is no defect on the surface of the boring tool 7, the amount of air entering the box body 35 is the same each time, and the position where the conductive slide plate 36 moves is the same, so that the warning light 38 can keep flashing on and off at the same frequency. When there is a defect on a certain part of the surface of the boring tool 7, when the defective part squeezes the friction head 29 to drive the sliding plug 27 to move, the moving distance of the sliding plug 27 will become shorter, and thus the amount of air entering the box body 35 will decrease. At this time, the moving distance of the conductive slide plate 36 decreases, and the conductive slide plate 36 cannot be separated from the conductive plate 37. At this time, the warning light 38 does not go out. Then, the staff can observe the flashing frequency of the warning light 38 to determine whether there is a defect on the surface of the boring tool 7. If the warning light 38 keeps flashing at the same frequency, the boring tool 7 is intact. If the flashing frequency of the warning light 38 is irregular, there is a defect on the surface of the boring tool 7, and the boring tool 7 needs to be replaced immediately to avoid the defective boring tool 7 affecting the boring quality.

[0057] When the boring tool 7 moves out of the annular seat 25, boring of the shaft can begin. While boring, an external pump body is started, and coolant is injected into the hollow boring shaft 5 through the liquid injection pipe 10. The coolant flows in the hollow boring shaft 5 and impacts the sealing plate 15, causing the sealing plate 15 to move leftward to the maximum position (as shown in the appendix Figure 5 ). Then, the coolant will rush out through the gap between the sealing plate 15 and the mounting ring 11 and then into the bored hole of the shaft being processed. The coolant can not only cool the shaft and the boring tool 7, but also flush out the debris in the bored hole, thus preventing the debris from accumulating in the bored hole and scratching the inner wall of the bored hole (when boring the hole, the hydraulic cylinder 40 is controlled intermittently by an external control program to ensure the boring quality).

[0058] In addition, since the boring tool 7 is in contact with the inner wall of the bored hole, during the boring process, there may be debris stuck between the boring tool 7 and the inner wall of the bored hole. At this time, simply flushing the bored hole with coolant may not be able to wash out the stuck debris, resulting in an incomplete cleaning situation. Therefore, during the rotation of the hollow boring shaft 5, it will drive the adjusting plate 17 to rotate together. When the adjusting plate 17 rotates to abut against the cam 22, it will push the adjusting plate 17 to move inward into the hollow boring shaft 5, thereby reducing the amount of coolant entering the hollow boring shaft 5. When the adjusting plate 17 separates from the cam 22, the adjusting plate 17 will reset under the action of the third spring 18, and at this time, the amount of coolant entering the hollow boring shaft 5 will increase. Therefore, during the boring process, the amount of coolant entering the hollow boring shaft 5 will alternately increase and decrease. Therefore, the impact force exerted by the coolant on the sealing plate 15 will also alternately increase and decrease. Then, in cooperation with the second spring 16, the sealing plate 15 will drive the P-shaped block 13 to slide reciprocally through the connecting rod 14. When the protruding part of the P-shaped block 13 moves to abut against the slide rod 6, the boring tool 7 will move outward a certain distance. When the concave part of the P-shaped block 13 moves into contact with the slide rod 6, the boring tool 7 will move inward. Therefore, during the boring process, the boring tool 7 will reciprocally move, thereby preventing debris from being stuck between the boring tool 7 and the inner wall of the bored hole, thus enhancing the cleaning effect.

[0059] The flushing coolant will finally fall into the recovery tank 23, and the debris in the coolant will be intercepted by the filter screen 24. Subsequently, the debris on the filter screen 24 can be recycled. After the boring is completed, the hydraulic cylinder 40 contracts, driving the boring tool 7 to reset for tool withdrawal. When the boring tool 7 moves into the annular seat 25 and contacts the friction head 29, friction is generated between the friction head 29 and the surface of the boring tool 7, which can clean the debris adhered to the surface of the boring tool 7. And the boring tool 7 will drive the sliding plug 27 to reciprocally seal and slide through the push rod 28. At this time, the coolant in the recovery tank 23 will be pumped into the liquid pumping cavity 271 through the one-way liquid inlet pipe 33. Then, the coolant in the liquid pumping cavity 271 will enter the cylindrical cavity 30 through the one-way liquid outlet hole 34. Finally, the coolant will be sprayed out through the communication groove 31 to wash the surface of the boring tool 7, further enhancing the cleaning effect on the boring tool 7.
