Description

Technical Field

[0001] The present invention relates to a lathe for processing tubular workpieces, and more specifically to an automatic lathe for deep processing of tubular workpieces. Background Art

[0002] A tubular workpiece is a mechanical part with a hollow cylindrical shape. Its basic structure is a hollow cylinder composed of a cylindrical surface and two end faces, and it is often used in various fields such as transmission shafts, hydraulic cylinder barrels, and intake pipes of engines. During production, an automatic lathe is often used to perform operations such as turning on the outer surface of the tubular workpiece to improve its dimensional accuracy and surface finish.

[0003] After the traditional lathe completes the turning operation of a single tubular workpiece, the workpiece usually directly falls from the fixture onto the chute on the operating table and rolls along the chute into the turnover box on the ground. Since a large amount of waste chips are generated during the turning process, the waste chips will accumulate in the chute, which is not convenient for cleaning. At the same time, some waste chips will slide along with the workpiece into the turnover box along the chute. Later, the staff needs to take out all the pipe fittings in the box and clean them, and the operation process is cumbersome, with poor flexibility, and the workpieces falling into the turnover box will be unevenly stacked, thus occupying space.

[0004] A large amount of metal dust and debris will be generated during the processing of tubular workpieces. The dust will accumulate on the surface of the equipment over a long period of time, increasing the cleaning difficulty. At the same time, if the dust enters the equipment, it will affect the normal operation and service life of the equipment, and the practicability is poor.

[0005] When the pipe fittings on the equipment are processed and need to be replaced with the next steel pipe, usually two guide plates on the conveying mechanism assist in transporting the pipe fittings to the fixture position of the equipment and are fed between the fixtures by the feeding structure. However, the guide plates are usually directly fixed to the feeding mechanism with bolts. When it is necessary to adjust the distance between the two guide plates according to the size of the pipe fittings, the bolts need to be repeatedly disassembled and tightened, and the operation efficiency is low.

Detailed implementation manners

[0036] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0037] As Figure 1 and Figures 5 - 9As shown in the figure, an automatic lathe for deep processing of tubular workpieces according to the present invention includes a lathe body 1, a shaking structure 5 installed on the lathe body 1, a fixing structure 6 provided on the shaking structure 5, and a limiting structure 7 cooperating with the shaking structure 5; the shaking structure 5 includes two mounting blocks 501 and a sliding rod 502 fixedly connected to the bottom surface of the mounting block 501. Two mounting blocks 501 are fixedly connected to the outer wall of the lathe body 1. Two bases 503 are fixedly connected to the lathe body 1. The bottom end of the sliding rod 502 is fixedly connected to the adjacent base 503. A bearing frame 504 is slidably connected between the two sliding rods 502. A rotating shaft 505 is rotatably connected between the two bases 503. A cam 506 is fixedly connected to both ends of the rotating shaft 505. During the rotation of the cam 506, it will contact the rollers 507 on both sides of the bearing frame 504, thereby driving the bearing frame 504 to move upward along the sliding rod 502. A connecting frame 508 is fixedly connected to the bottom surface of one of the bases 503. A second motor 509 is fixedly connected to the connecting frame 508. The output shaft of the second motor 509 is fixedly connected to the rotating shaft 505. Rollers 507 are rotatably connected to both sides of the bearing frame 504, and the rotating shaft 505 will drive the cams 506 at both ends to rotate. The top end of the cam 506 contacts the roller 507. A bearing plate 510 is fixedly connected between the two bases 503. The bearing plate 510 between the two bases 503 supports the storage box 601, improving the stability. During the turning process, the waste chips falling into the chute will be blown into the storage box 601 by the air blowing pipe 307. At this time, the second motor 509 located on the connecting frame 508 will drive the rotating shaft 505 to rotate between the two bases 503. At this time, the up and down shaking of the bearing frame 504 and the storage box 601 is realized by the rotation of the cam 506. At the same time, the workpieces inside the storage box 601 will be shaken evenly, avoiding the problems of large gaps between workpieces and occupying space caused by uneven accumulation of workpieces. The sliding rod 502 is fixed between the mounting block 501 and the base 503, with strong firmness.

[0038] Specifically, as Figure 1 , Figure 5 , Figure 6 and Figure 9As shown, the upper surface of the load-bearing frame 504 abuts against the storage box 601. When the storage box 601 shakes up and down, not only will the waste chips that fall into the interior of the storage box 601 fall to the ground through the through slot 602, but also two guide rods 603 are slidably connected to one end of the load-bearing frame 504 near the outside. A fixing plate 604 is fixedly connected between the two guide rods 603. By rotating the knob 606 to move the knob 606 outward, the fixing plate 604 will no longer abut against the storage box 601, thus facilitating the removal of the storage box 601 filled with workpieces from the load-bearing frame 504 and facilitating the replacement of the storage box 601. At the same time, the fixing plate 604 plays a fixing role for the storage box 601 with strong firmness. The fixing plate 604 abuts against the outer wall of the storage box 601. A first tension spring 605 is fixedly connected between the end of one of the guide rods 603 and the load-bearing frame 504. Under the reset action of the first tension spring 605, the guide rod 603 drives the fixing plate 604 to move outward. The knob 606 is threadedly connected to the central position of the load-bearing frame 504, and the end of the knob 606 abuts against the outer wall of the storage box 601. The processed workpieces will fall onto the inclined surface of the lathe body 1 under the action of gravity and then roll along the inclined surface to the storage box 601 at its bottom until the storage box 601 is filled with workpieces.

[0039] Specifically, as Figures 5 - 7 shown, a clamping strip 701 is slidably connected to the side of the load-bearing frame 504. A second tension spring 703 is fixedly connected between the inner side of the pull plate 702 and the outer wall of the load-bearing frame 504. A limiting hole 704 is formed in one of the sliding rods 502 near the clamping strip 701. Two baffle plates 705 are fixedly connected to the central position of the load-bearing frame 504. The blocking plate 705 can block the workpieces in the inclined groove to prevent the workpieces from falling to the ground during the replacement of the storage box 601. Second springs 706 are fixedly connected between the two ends of the load-bearing frame 504 and the adjacent bases 503 respectively. The clamping strip 701 and the pull plate 702 are re-engaged with the limiting hole 704 under the reset action of the second tension spring 703. After the storage box 601 is removed from the load-bearing frame 504, the load-bearing frame 504 slides upward along the sliding rod 502 to the topmost position under the action of the two second springs 706. At this time, the load-bearing frame 504 drives the two baffle plates 705 at the central position to move upward to the designated position. At the same time, when the load-bearing frame 504 moves upward to the topmost position, the position of the load-bearing frame 504 is fixed, avoiding the shaking of the load-bearing frame 504 during the fixing of the storage box 601, improving the stability and the replacement efficiency of the storage box 601.

[0040] Specifically, as Figures 1 - 4 and Figure 9As shown, a mounting seat 201 is fixedly connected to the turning machine body 1. The telescopic end of the hydraulic cylinder 202 is fixedly connected to a fixed center 203. Another mounting seat 201 is rotatably connected to a rotating center 204. When the workpiece is sent by the feeding rack 411 between the fixed center 203 and the rotating center 204, the fixed center 203 cooperates with the rotating center 204 to clamp the workpiece, with strong firmness. A first motor 207 is fixedly connected to the turning machine body 1 near the rotating center 204. Pulley 205 is fixedly connected to the output shaft of the first motor 207 and the end of the rotating center 204. A belt 206 is wound between the two pulleys 205. The first motor 207 drives the other pulley 205 at the end of the rotating center 204 to rotate through the pulley 205 on the output shaft and belt drive. At this time, the rotating center 204 rotates on the mounting seat 201, and at the same time, the rotating center 204 drives the workpiece to rotate, thereby improving the turning efficiency. The hydraulic cylinder 202 drives the fixed center 203 to move towards the center position, and then the feeding rack 411 returns to the initial position. At the same time, the next workpiece between the two positioning plates 404 repeats to fall onto the feeding rack 411, and circulates in sequence and is sent to the fixture.

[0041] Specifically, as Figures 1 - 4 , Figure 9 and Figure 10 shown, a mounting plate 301 is fixedly connected between the two mounting seats 201. A filter screen 303 is clamped to the bottom surface of the dust suction pipe 302. The filter screen 303 is clamped to the bottom of the dust suction pipe 302, which can effectively prevent dust from being sucked into the internal of the vacuum pump 304, with strong practicability. A vacuum pump 304 is fixedly connected to the top end of one of the mounting seats 201. A connecting pipe 305 is fixedly connected between the suction port of the vacuum pump 304 and the dust suction pipe 302. A shielding plate 306 is fixedly connected to the turning machine body 1. The shielding plate 306 can effectively prevent waste chips from splashing into the gap, which is convenient for cleaning. An air blowing pipe 307 is fixedly connected to the inner wall of the turning machine body 1. An air blowing groove 308 is formed inside the air blowing pipe 307. A connecting port 309 is fixedly connected to the end of the air blowing pipe 307. Since the air blowing groove 308 inside the air blowing pipe 307 is connected to the external air source through the connecting port 309, the waste chips falling on the inclined surface of the turning machine body 1 will be blown by the air blowing pipe 307 towards the bottom end of the inclined surface, which is convenient for subsequent cleaning operations. The connecting port 309 penetrates through the side wall of the turning machine body 1 and is connected to the external air source. Then, the driving mechanism installed on the turning machine body 1 drives the turning tool to move, so as to realize the all-round turning operation on the outer surface of the workpiece. However, a large amount of waste chips and dust will be generated during the turning process. At the same time, the vacuum pump 304 starts to operate. The vacuum pump 304 makes the dust suction pipe 302 suck the dust generated during the turning process through the connecting pipe 305. Since the dust suction pipe 302 is installed above the workpiece through the mounting plate 301, the dust suction effect is improved.

[0042] Specifically, as Figure 1 , Figure 3 , Figure 4 and Figures 9 - 11 shown, a support frame 401 is fixedly connected to the outer wall of the lathe body 1. Since the blanking frame 402 is installed on the outer wall of the lathe body 1 through the support frame 401 at the bottom, the stability is strong. Two guide bars 403 are respectively slidably connected to both sides of the blanking frame 402. A positioning plate 404 is fixedly connected between the two guide bars 403 on the same side. A first spring 405 is fixedly connected between the ends of the two guide bars 403 and the outer wall of the blanking frame 402. Nuts 406 are threadedly connected to both of the two guide bars 403. The nuts 406 are in contact with the outer wall of the blanking frame 402. A support plate 409 is fixedly connected to the outer wall of the lathe body 1. A hydraulic rod 410 is fixedly connected to the support plate 409. The hydraulic rod 410 on the support plate 409 drives the feeding frame 411 and the workpiece that has rolled onto the feeding frame 411 to move towards the fixture of the equipment. A feeding frame 411 is slidably connected to one end of the blanking frame 402 close to the lathe body 1. The feeding frame 411 is fixedly connected to the telescopic end of the hydraulic rod 410. A driving rod 407 is rotatably connected to the blanking frame 402. A blocking frame 408 is threadedly connected to the bottom end of the driving rod 407. Then, adjust the height of the blocking frame 408 according to the outer diameter of the workpiece. Just rotate the driving rod 407, and the driving rod 407 drives the blocking frame 408 to move up and down to adjust the height until the distance between the bottom end of the blocking frame 408 and the bottom surface of the blanking frame 402 can allow a single workpiece to pass through. Carry the tubular workpiece to be processed into the inside of the blanking frame 402. Since the bottom surface of the blanking frame 402 is an inclined surface, the workpiece rolls towards the lower end under the action of gravity until the frontmost workpiece rolls onto the feeding frame 411. At the same time, the other workpieces are neatly arranged in turn on the bottom inclined surface of the blanking frame 402. During the process of the workpiece rolling on the bottom inclined surface of the blanking frame 402, the positioning plates 404 on both sides play a guiding role for the workpiece. At the same time, when processing workpieces with a smaller length is required, just press the two guide bars 403 towards the center position respectively. At this time, the ends of the guide bars 403 compress the first spring 405. Then rotate the nuts 406 to make the nuts 406 move outward in the reverse direction until the nuts 406 are in contact with the side of the blanking frame 402. At this time, the adjustment of the distance between the two positioning plates 404 is completed, which is convenient for adapting to workpieces of different lengths. Until the feeding frame 411 transports the workpiece to between the fixed center 203 and the rotary center 204, at this time, the automatic feeding of the workpiece is realized, and the turning efficiency of the workpiece is improved.

[0043] When the present invention is in use, the tubular workpiece to be processed is transported into the interior of the blanking rack 402, and then the height of the blocking rack 408 is adjusted according to the outer diameter of the workpiece. Only by rotating the driving rod 407, the driving rod 407 drives the blocking rack 408 to move up and down to adjust the height until the distance between the bottom end of the blocking rack 408 and the bottom surface of the blanking rack 402 can allow a single workpiece to pass through. Since the bottom surface of the blanking rack 402 is an inclined surface, the workpiece rolls towards the lower end under the action of gravity until the foremost workpiece rolls onto the feeding rack 411. At the same time, the other workpieces are neatly arranged in sequence on the bottom inclined surface of the blanking rack 402. Since the blanking rack 402 is installed on the outer wall of the lathe body 1 through the bottom support frame 401, the stability is strong. And during the process of the workpiece rolling on the bottom inclined surface of the blanking rack 402, the positioning plates 404 on both sides play a guiding role for the workpiece. At the same time, when processing workpieces with a smaller length is required, only need to press the guiding strips 403 on both sides towards the center position respectively. At this time, the end of the guiding strip 403 compresses the first spring 405, and then rotate the nut 406 to make the nut 406 move outward in the reverse direction until the nut 406 abuts against the side of the blanking rack 402. At this time, the adjustment of the distance between the two positioning plates 404 is completed, which is convenient for adapting to workpieces of different lengths. Then, the hydraulic rod 410 on the support plate 409 drives the feeding rack 411 and the workpiece that has rolled onto the feeding rack 411 to move towards the fixture of the equipment until the feeding rack 411 transports the workpiece between the fixed center 203 and the rotary center 204. At this time, the automatic feeding of the workpiece is realized, which improves the turning efficiency of the workpiece;

[0044] When the workpiece is transported by the feeding rack 411 between the fixed center 203 and the rotary center 204, the hydraulic cylinder 202 drives the fixed center 203 to move towards the center position until the fixed center 203 cooperates with the rotary center 204 to clamp the workpiece, and the firmness is strong. Then the feeding rack 411 returns to the initial position. At the same time, the next workpiece between the two positioning plates 404 repeats to fall onto the feeding rack 411, and is circulated in sequence and sent to the fixture. Then, the first motor 207 drives the other pulley 205 at the end of the rotary center 204 to rotate through the pulley 205 on the output shaft and belt drive. At this time, the rotary center 204 rotates on the mounting seat 201, and at the same time, the rotary center 204 drives the workpiece to rotate, thereby improving the turning efficiency;

[0045] Next, it is installed on the lathe body 1, and the driving mechanism drives the turning tool to move, so as to realize the all-round turning operation on the outer surface of the workpiece. However, a large amount of waste chips and dust will be generated during the turning process. At this time, the baffle 306 installed on the driving mechanism can effectively prevent the waste chips from splashing into the gap, which is convenient for cleaning. At the same time, the vacuum pump 304 starts to operate. The vacuum pump 304 makes the dust suction pipe 302 suck the dust generated during the turning process through the connecting pipe 305. Since the dust suction pipe 302 is installed directly above the workpiece through the mounting plate 301, the dust suction effect is improved. And because the filter screen 303 is clamped at the bottom of the dust suction pipe 302, it can effectively prevent the dust from being sucked into the interior of the vacuum pump 304, and it has strong practicability. Since the air blowing groove 308 inside the air blowing pipe 307 is connected to the external air source through the connection port 309, the waste chips falling on the inclined surface of the lathe body 1 will be blown by the air blowing pipe 307 to the bottom end of the inclined surface, which is convenient for subsequent cleaning operations;

[0046] The processed workpiece will fall onto the inclined surface of the lathe body 1 under the action of gravity, and then roll along the inclined surface into the storage box 601 at its bottom end until the storage box 601 is full of workpieces. When it is necessary to replace the storage box 601, just rotate the knob 606 to move the knob 606 outward. At this time, the guide rod 603 drives the fixing plate 604 to move outward under the reset action of the first pulling spring 605. At this time, the fixing plate 604 no longer abuts against the storage box 601, so it is convenient to remove the storage box 601 full of workpieces from the bearing frame 504, which is convenient for the replacement of the storage box 601. At the same time, the fixing plate 604 plays a fixing role on the storage box 601, and the firmness is strong. After the storage box 601 is removed from the bearing frame 504, the bearing frame 504 slides upward along the sliding rod 502 to the topmost position under the action of the two second springs 706. At this time, the bearing frame 504 drives the two baffle plates 705 at the central position to move upward to the designated position. The baffle plate 705 can block the workpieces in the inclined groove to prevent the workpieces from falling to the ground during the replacement of the storage box 601. At the same time, when the bearing frame 504 moves upward to the topmost position, the clamping strip 701 and the pulling plate 702 are re-engaged with the limiting hole 704 under the reset action of the second pulling spring 703. At this time, the position of the bearing frame 504 is fixed, which avoids the shaking of the bearing frame 504 during the fixing of the storage box 601, improves the stability, and improves the replacement efficiency of the storage box 601;

[0047] During the turning process, the waste chips that fall into the chute will be blown into the storage box 601 by the air blowing pipe 307. At this time, the second motor 509 on the connecting frame 508 will drive the rotating shaft 505 to rotate between the two bases 503, and the rotating shaft 505 will drive the cams 506 at both ends to rotate. During the rotation of the cams 506, they will contact the rotating wheels 507 on both sides of the bearing frame 504, thereby driving the bearing frame 504 to move upward along the sliding rod 502. At this time, by rotating the cam 506, the up and down shaking of the bearing frame 504 and the storage box 601 is realized. The up and down shaking of the storage box 601 not only makes the waste chips that fall into the storage box 601 fall to the ground through the through groove 602, but also makes the workpieces inside the storage box 601 shake evenly, avoiding the problems of large gaps between workpieces and occupying space caused by uneven accumulation. The sliding rod 502 is fixed between the mounting block 501 and the base 503, with strong firmness, and the bearing plate 510 between the two bases 503 plays a supporting role for the storage box 601, improving the stability.
