Description

Technical Field

[0001] The invention relates to the technical field of boring machines, in particular 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 accuracy, reduce surface roughness, and better correct the deviation of the original hole axis.

[0003] At present, in the boring process, especially for the processing of deep holes or high-precision holes, chip removal and tool cleaning have always been the key issues that plague the processing quality and efficiency. During processing, the traditional single-axis horizontal boring machine has poor chip removal, which can easily lead to chip accumulation, scratch the processed hole wall, and affect the surface roughness and dimensional accuracy. In addition, a large amount of chips and cutting fluid residues will be attached to the tool during the long-term cutting process. If they are not cleaned in time, the cutting performance of the tool will be affected and the tool life will be shortened. In addition, for some double-hole or multi-hole processing with coaxiality requirements, the single-axis boring machine needs to position the processing multiple times, and the cumulative error is large, which is difficult to meet the high-precision requirements.

At this time, the coolant in the recovery box will be pumped into the pump liquid cavity through the one-way liquid inlet pipe, and then the coolant in the pump liquid cavity will enter the cylindrical cavity through the one-way liquid outlet hole. Finally, the coolant will be sprayed out through the connecting groove to wash the boring tool surface, further enhancing the cleaning effect of the boring tool; 5. By setting up a detection mechanism, the surface of the boring tool can be inspected before boring. If the warning light keeps flashing at the same frequency, the boring tool is intact. If the warning light flashes at an irregular frequency, there are defects on the surface of the boring tool. The boring tool needs to be replaced immediately to avoid the boring tool with defects on the surface affecting the boring quality. BRIEF DESCRIPTION OF THE DRAWINGS

When boring holes, the hydraulic cylinder 40 is intermittently advanced through an external control program to ensure the boring quality, which is a prior art.

[0021] A cleaning mechanism, the cleaning mechanism includes two rotating joints 9 symmetrically fixedly connected to the side wall of the mounting seat 4 through a fixed axis, one end of the two hollow boring shafts 5 penetrates the side wall of the mounting seat 4 and is respectively fixedly connected to the two rotating joints 9, a liquid injection tube 10 is fixedly connected to the side wall of the rotating joint 9, and the other end of the liquid injection tube 10 is connected to the external pump body, a mounting ring 11 is fixedly connected to the inner wall of the hollow boring shaft 5, two cavities 12 are symmetrically opened in the mounting ring 11, and the inner walls of the two cavities 12 are slidably connected to P-type blocks 13, one end of the sliding rod 6 extends into the cavity 12 and slides against the side wall of the P-type block 13, a connecting rod 14 is fixedly connected to the side wall of the P-type block 13, one end of the connecting rod 14 penetrates the side wall of the mounting 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, and 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-type block 13; A driving mechanism is installed on the mounting seat 4 , and a flow regulating mechanism is installed on the hollow boring shaft 5 .

[0022] The flow regulating mechanism includes an adjusting plate 17 which is sealingly and slidably connected to the side wall of the hollow boring shaft 5. The side wall of the adjusting plate 17 is chamfered. One end of the adjusting plate 17 extends to the inside of 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 fixedly connected to the adjusting plate 17. The side wall of the mounting seat 4 is fixedly connected to a cam 22 which cooperates with the adjusting plate 17 through a fixed shaft.

[0023] 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 passes through the cam 22 and the side wall of the mounting seat 4 and is fixedly connected to the first gear 20. The side walls of the two hollow boring shafts 5 are fixedly connected to the second gears 21, and each second gear 21 is meshed with the first gear 20.

[0024] Furthermore, when boring, the motor 19 is driven and the external pump body is started at the same time, and the coolant is injected into the hollow boring shaft 5 through the injection pipe 10. The coolant flows in the hollow boring shaft 5 and impacts the sealing plate 15, so that the sealing plate 15 moves to the left to the maximum position (as shown in the attached figure). Figure 5 As shown), the coolant will then rush out through the gap between the sealing plate 15 and the mounting ring 11, and then rush into the boring hole of the shaft. The coolant can not only cool the shaft and the boring tool 7, but also flush out the debris in the boring hole, thereby preventing the debris from accumulating in the boring hole and causing scratches on the inner wall of the boring hole.

[0025] It should be noted that after boring is completed, the pumping of coolant is stopped, and the sealing plate 15 will be reset under the action of the second spring 16 to form a seal with the mounting ring 11 again, thereby preventing the mixture of coolant and debris in the boring hole from flowing back into the hollow boring shaft 5.

[0026] It is worth mentioning that, due to the fit between the boring tool 7 and the inner wall of the boring hole, debris may be stuck between the boring tool 7 and the inner wall of the boring hole during the boring process. At this time, simply flushing the boring hole with coolant may not be able to flush out the stuck debris, and then there will be a situation where cleaning is not in place. Therefore, during the rotation of the hollow boring shaft 5, it will drive the adjustment plate 17 to rotate together, and when the adjustment plate 17 rotates to abut against the cam 22, it will push the adjustment plate 17 to move inside the hollow boring shaft 5, thereby reducing the amount of coolant entering the hollow boring shaft 5, and when the adjustment plate 17 is separated from the cam 22, the adjustment plate 17 will be reset under the action of the third spring 18, and the coolant entering the hollow boring shaft 5 will be The amount of coolant will increase, so during the boring process, the amount of coolant entering the hollow boring shaft 5 will increase and decrease alternately, so the impact force of the coolant on the sealing plate 15 will also increase and decrease alternately, and then in conjunction with the second spring 16, the sealing plate 15 will drive the P-type block 13 to slide back and forth through the connecting rod 14, and when the protruding part of the P-type block 13 moves to abut against the slide bar 6, the boring tool 7 will move outward for a distance, and when the concave part of the P-type block 13 moves to contact the slide bar 6, the boring tool 7 will move inward, so during the boring process, the boring tool 7 will move back and forth, thereby preventing debris from being stuck between the boring tool 7 and the inner wall of the boring hole, thereby enhancing the cleaning effect.

[0027] Two recovery boxes 23 are symmetrically fixedly connected to the lower end of the processing platform 2 . The upper ends of the two recovery boxes 23 penetrate the upper end of the processing platform 2 . A filter screen 24 is fixedly connected to the inner wall of the recovery box 23 .

[0028] Furthermore, the flushed coolant will eventually fall into the recovery box 23, and the debris in the coolant will be intercepted by the filter 24, and the debris on the filter 24 can be subsequently recycled.

[0029] A knife washing mechanism is installed on the processing platform 2, and the knife washing mechanism includes two annular seats 25 symmetrically fixedly connected to the upper end of the processing platform 2 through a fixed axis, and two slide cylinders 26 are symmetrically fixedly connected to the side walls of the annular seats 25. The inner walls of the two slide cylinders 26 are sealed and slidably connected with slide plugs 27. The slide plugs 27 divide the interior of the slide cylinder 26 into two parts: a pump liquid chamber 271 and a pump air chamber 272. A push rod 28 is fixedly connected to the side wall of the slide plug 27, and one end of the push rod 28 passes through the inner wall of the annular seat 25 and is fixedly connected to a friction head 29.

[0030] The knife washing mechanism also includes a cylindrical cavity 30 opened in the push rod 28, a connecting groove 31 is opened in the friction head 29, one end of the connecting groove 31 is connected to the cylindrical cavity 30, the sliding plug 27 and the inner wall of the sliding cylinder 26 are fixedly connected with a fourth spring 32, the pump liquid cavity 271 is connected with the recovery box 23 through a one-way liquid inlet pipe 33, the one-way liquid inlet pipe 33 only allows the coolant in the recovery box 23 to enter the pump liquid cavity 271, and a plurality of one-way liquid outlet holes 34 are opened on the inner wall of the cylindrical cavity 30, and the one-way liquid outlet holes 34 only allow the coolant in the pump liquid cavity 271 to enter the cylindrical cavity 30.

[0031] Furthermore, after boring is completed, the hydraulic cylinder 40 contracts, driving the boring tool 7 to reset and retract. When the boring tool 7 moves into the annular seat 25 and contacts the friction head 29, the friction head 29 and the surface of the boring tool 7 generate friction, which can clean up the debris adhering to the surface of the boring tool 7, and the boring tool 7 will drive the sliding plug 27 to slide back and forth in a sealed manner through the push rod 28. At this time, the coolant in the recovery box 23 will be drawn into the pump liquid chamber 271 through the one-way liquid inlet pipe 33, and then the coolant in the pump liquid chamber 271 will enter the cylindrical cavity 30 through the one-way liquid outlet hole 34. Finally, the coolant will be sprayed out through the connecting groove 31 to rinse the surface of the boring tool 7, further enhancing the cleaning effect of the boring tool 7.

[0032] A detection mechanism is installed on the mounting seat 4, and the detection mechanism includes two boxes 35 symmetrically fixedly connected to the upper end of the mounting seat 4. The inner wall of the box 35 is sealed and slidably connected with a conductive slide plate 36. The box 35 is connected to the pump air cavity 272 through a connecting pipe 39.

[0033] The detection mechanism also includes a warning light 38 fixedly connected to the upper end of the box body 35. A conductive plate 37 is embedded in the inner wall of the box body 35. The conductive slide plate 36, the conductive plate 37, the warning light 38 and the external power supply are electrically connected through wires.

[0034] Furthermore, the hydraulic cylinder 40 will drive the mounting seat 4 to slide on the inner wall of the slide groove 3, drive the hollow boring shaft 5 to move, and make the boring tool 7 slowly enter 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 slide plug 27 to move. At this time, the air in the pump air chamber 272 will enter the box body 35 through the connecting pipe 39, pushing the conductive slide plate 36 to move, and when the slide plug 27 moves to the maximum distance, the air pumped into the box body 35 at this time just pushes the conductive slide plate 36 to separate from the conductive plate 37, and the warning light 38 goes out at this time, and so on. 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 of the conductive slide plate 36 moves The same makes it possible for the warning light 38 to keep turning on and off at the same frequency. When there is a defect somewhere on the surface of the boring tool 7, when the friction head 29 squeezes the defective part to drive the slide plug 27 to move, the distance moved by the slide plug 27 will become shorter, and the amount of air entering the box body 35 will be reduced. At this time, the moving distance of the conductive slide plate 36 is reduced, and the conductive slide plate 36 cannot be separated from the conductive plate 37. At this time, the warning light 38 will not be extinguished, and 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 warning light 38 has an irregular flashing frequency, 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 defect on the surface affecting the boring hole quality.

[0035] In the present invention, the shaft to be bored is first placed between the two clamping plates 43, and 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, and then the motor 19 is started and the hydraulic cylinder 40 is driven to extend synchronously, the motor 19 will drive the first gear 20 to rotate, and then drive the second gear 21 to rotate, thereby driving the hollow boring shaft 5 to rotate, driving the boring tool 7 to rotate, and the hydraulic cylinder 40 will drive the mounting seat 4 to slide on the inner wall of the slide groove 3, with The hollow boring shaft 5 moves, 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 slide plug 27 to move. At this time, the air in the pump air chamber 272 will enter the box body 35 through the connecting pipe 39, pushing the conductive slide plate 36 to move. When the slide plug 27 moves to the maximum distance, the air pumped into the box body 35 just pushes the conductive slide plate 36 to the position close to the slide plug 27. The conductive plate 37 is separated, and the warning light 38 is off. This goes on and on. 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 conductive slide plate 36 moves to the same position, so that the warning light 38 can keep turning on and off at the same frequency. When there is a defect somewhere on the surface of the boring tool 7, when the friction head 29 squeezes the defective part to drive the slide plug 27 to move, the distance moved by the slide plug 27 will become shorter, and the amount of air entering the box body 35 will be reduced. At this time, the moving distance of the conductive slide plate 36 is reduced, and the conductive slide plate 36 cannot be separated from the conductive plate 37. At this time, the warning light 38 will not be off, and 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 warning light 38 has an irregular flashing frequency, 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 defect on the surface affecting the boring hole quality.

[0036] When the boring tool 7 moves out of the annular seat 25, the shaft can be bored. While boring, the external pump body is started to inject coolant into the hollow boring shaft 5 through the 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 attached figure). Figure 5 As shown), the coolant will then rush out through the intervals between the sealing plate 15 and the mounting ring 11, and then rush into the boring hole of the shaft. The coolant can not only cool the shaft and the boring tool 7, but also flush out the debris in the boring hole, thereby preventing the debris from accumulating in the boring hole and causing scratches on the inner wall of the machined boring hole (when machining the boring hole, the hydraulic cylinder 40 is intermittently advanced through an external control program to ensure the quality of the boring hole).

[0037] In addition, since the boring tool 7 fits closely with the inner wall of the boring hole, debris may be stuck between the boring tool 7 and the inner wall of the boring hole during the boring process. At this time, simply flushing the boring hole with coolant may not be able to flush out the stuck debris, and thus the cleaning may not be in place. Therefore, during the rotation of the hollow boring shaft 5, it will drive the adjustment plate 17 to rotate together, and when the adjustment plate 17 rotates to abut against the cam 22, it will push the adjustment plate 17 to move inside the hollow boring shaft 5, thereby reducing the amount of coolant entering the hollow boring shaft 5, and when the adjustment plate 17 is separated from the cam 22, the adjustment plate 17 will be reset under the action of the third spring 18, and the coolant entering the hollow boring shaft 5 will be The amount of coolant will increase, so during the boring process, the amount of coolant entering the hollow boring shaft 5 will increase and decrease alternately, so the impact force of the coolant on the sealing plate 15 will also increase and decrease alternately, and then cooperate with the second spring 16, the sealing plate 15 will drive the P-type block 13 to slide back and forth through the connecting rod 14, and when the protruding part of the P-type block 13 moves to abut against the slide bar 6, the boring tool 7 will move outward for a distance, and when the concave part of the P-type block 13 moves to contact the slide bar 6, the boring tool 7 will move inward, so during the boring process, the boring tool 7 will move back and forth, thereby avoiding debris from being stuck between the boring tool 7 and the inner wall of the boring hole, thereby enhancing the cleaning effect.

[0038] The flushing coolant will eventually fall into the recovery box 23, and the debris in the coolant will be intercepted by the filter 24, and the debris on the filter 24 can be recycled later. After the boring is completed, the hydraulic cylinder 40 contracts, driving the boring tool 7 to reset and retract. When the boring tool 7 moves into the annular seat 25 and contacts the friction head 29, the friction head 29 and the surface of the boring tool 7 produce friction, which can clean up the debris adhering to the surface of the boring tool 7, and the boring tool 7 will drive the sliding plug 27 to slide back and forth in a sealed manner through the push rod 28. At this time, the coolant in the recovery box 23 will be drawn into the pump liquid chamber 271 through the one-way liquid inlet pipe 33, and then the coolant in the pump liquid chamber 271 will enter the cylindrical cavity 30 through the one-way liquid outlet hole 34. Finally, the coolant will be sprayed out through the connecting groove 31 to flush the surface of the boring tool 7, further enhancing the cleaning effect of the boring tool 7.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
