Description

TECHNICAL FIELD

[0001] The present application relates to a tubular workpiece machining lathe, in particular to an automatic lathe for deep processing of tubular workpieces. BACKGROUND

[0002] The tubular workpiece is a mechanical part with a hollow cylindrical shape, and its basic structure is a hollow cylinder composed of a cylindrical surface and two end surfaces. It is commonly used in various transmission shafts, hydraulic cylinder barrels, engine intake pipes and other fields. An automatic lathe is often used to turn the outer surface of the tubular workpiece during production 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 falls directly from the clamp to the chute on the operation table and rolls along the chute into the turnover box on the ground. A large amount of waste will be generated during turning, which will accumulate in the chute and is not easy to clean. At the same time, part of the waste will slide along the chute with the workpiece into the turnover box. The operator needs to take out all the pipes in the box and clean them later. The operation process is complicated, flexible, 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. Dust will accumulate on the surface of the equipment for a long time, increasing the difficulty of cleaning. If the dust enters the interior of the equipment, it will affect the normal operation and service life of the equipment, and the practicability is poor.

[0005] When the pipe processing on the equipment is completed and the next steel pipe needs to be replaced, the pipe is usually transported to the clamp position of the equipment by two guide plates on the conveying mechanism, and then fed into the clamp by the feeding structure. However, the guide plates are usually directly fixed on the feeding mechanism by bolts. When the distance between the two guide plates needs to be adjusted according to the size of the pipe, the bolts need to be repeatedly disassembled and tightened, which is low in operation efficiency.

When the storage box 601 is removed from the load-bearing frame 504, the load-bearing frame 504 slides upward to the top end along the sliding rod 502 under the action of the two second springs 706. At this time, the load-bearing frame 504 drives the two blocking plates 705 at the center to move upward to the specified position. At the same time, when the load-bearing frame 504 moves upward to the top end, the position of the load-bearing frame 504 is fixed, avoiding the load-bearing frame 504 from shaking during the fixing of the storage box 601, improving the stability and the replacement efficiency of the storage box 601.

[0041] Specifically, as shown in Figure 1 , Figure 3 , Figure 4 and Figures 9-11 , the outer wall of the turning machine body 1 is fixedly connected with a support frame 401, since the blanking frame 402 is installed on the outer wall of the turning machine body 1 through the bottom support frame 401, the stability is strong, the two sides of the blanking frame 402 are respectively slidably connected with two guide bars 403, the two guide bars 403 located on the same side are fixedly connected with a positioning plate 404, the end portions of the two guide bars 403 are fixedly connected with a first spring 405 and are threadedly connected with a nut 406 between the outer wall of the blanking frame 402, the nut 406 and the outer wall of the blanking frame 402 are in mutual abutment, the outer wall of the turning machine body 1 is fixedly connected with a support plate 409, the support plate 409 is fixedly connected with a hydraulic rod 410, the hydraulic rod 410 on the support plate 409 drives the feeding frame 411 and the workpiece rolled onto the feeding frame 411 to move to the direction of the clamp of the equipment, one end of the blanking frame 402 close to the turning machine body 1 is slidably connected with the feeding frame 411, the feeding frame 411 is fixedly connected between the extension end of the hydraulic rod 410, the blanking frame 402 is rotatably connected with a driving rod 407, the bottom end of the driving rod 407 is threadedly connected with a blocking frame 408, then the height of the blocking frame 408 is adjusted according to the outer diameter of the workpiece, only the driving rod 407 is rotated, the driving rod 407 drives the blocking frame 408 to move to adjust the height, until the spacing between the bottom end of the blocking frame 408 and the bottom surface of the blanking frame 402 can meet the passing of a single workpiece, the tubular workpiece to be processed is carried into the inside of the blanking frame 402, since the bottom surface of the blanking frame 402 is inclined, then the workpiece rolls to the end with lower height under the action of gravity, until the workpiece at the front end rolls onto the feeding frame 411, and other workpieces are sequentially and neatly arranged on the bottom inclined surface of the blanking frame 402, and in the rolling process of the workpiece on the bottom inclined surface of the blanking frame 402, the positioning plates 404 on the two sides play a guiding role on the workpiece, and when a workpiece with smaller length needs to be processed, only the guide bars 403 on the two sides are pressed to the center position, at this time the end portions of the guide bars 403 compress the first springs 405, then the nut 406 is rotated to move reversely outward until the nut 406 abuts against the side of the blanking frame 402, at this time the adjustment of the spacing between the two positioning plates 404 is completed, which is convenient for adapting to workpieces with different lengths, until the feeding frame 411 delivers 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.

[0042] The application is used, the tubular workpiece to be processed is transported to the inside of the blanking frame 402, then the height of the blocking frame 408 is adjusted according to the outer diameter of the workpiece, only the driving rod 407 is rotated, the driving rod 407 drives the blocking frame 408 to move upwards to adjust the height, until the spacing between the bottom end of the blocking frame 408 and the bottom surface of the blanking frame 402 can meet the passing of a single workpiece, since the bottom surface of the blanking frame 402 is inclined, and then the workpiece rolls to the end with low height under the action of gravity, until the workpiece at the front end rolls to the feeding frame 411, and other workpieces are arranged in order on the inclined bottom surface of the blanking frame 402, since the blanking frame 402 is installed on the outer wall of the turning machine body 1 through the bottom support frame 401, the stability is high, and the positioning plates 404 on both sides play a guiding role for the workpiece during the rolling process of the workpiece on the inclined bottom surface of the blanking frame 402, and when the workpiece with smaller length needs to be processed, only the guide strips 403 on both sides are pressed to the center position, at this time the end of the guide strip 403 is compressed to the first spring 405, then the nut 406 is rotated, the nut 406 moves reversely to the outside, until the nut 406 abuts against the side of the blanking frame 402, at this time the adjustment of the spacing between the two positioning plates 404 is completed, which is convenient for adapting to workpieces with different lengths, then the hydraulic rod 410 on the support plate 409 drives the feeding frame 411 and the workpiece rolled to the feeding frame 411 to move to the direction of the clamp of the equipment, until the feeding frame 411 delivers the workpiece to the position 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 workpiece is delivered to the position between the fixed center 203 and the rotary center 204 by the feeding frame 411, the hydraulic cylinder 202 drives the fixed center 203 to move to the center position, until the fixed center 203 clamps the workpiece in cooperation with the rotary center 204, the firmness is high, then the feeding frame 411 returns to the initial position, and the next workpiece between the two positioning plates 404 falls to the feeding frame 411, and is delivered to the clamp in turn and circulates, then the first motor 207 drives the other belt pulley 205 at the end of the rotary center 204 to rotate through the belt transmission of the belt pulley 205 on the output shaft, at this time the rotary center 204 rotates on the mounting seat 201, and the rotary center 204 drives the workpiece to rotate, thereby improving the turning efficiency;

[0044] Then the driving mechanism installed on the lathe body 1 drives the turning tool to move, so as to realize the full turning operation on the outer surface of the workpiece. However, a large amount of waste and dust will be generated during the turning process. At this time, the shutter 306 installed on the driving mechanism can effectively prevent the waste from splashing into the gap, and facilitate 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 above the workpiece through the mounting plate 301, the dust suction effect is improved. Moreover, since the bottom of the dust suction pipe 302 is clamped with the filter screen 303, the dust can be effectively prevented from being sucked into the inside of the vacuum pump 304. The utility model has strong practicability. Since the blowing groove 308 in the blowing pipe 307 is connected with the external air source through the connecting port 309, the waste falling on the inclined surface of the lathe body 1 will be blown to the bottom end of the inclined surface by the blowing pipe 307, which facilitates subsequent cleaning operation.

[0045] The finished workpiece will fall on 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 the bottom end, until the storage box 601 is filled with workpieces. When it is necessary to replace the storage box 601, only the knob 606 is rotated to move the knob 606 outward. At this time, the guide rod 603 drives the fixed plate 604 to move outward under the resetting action of the first tension spring 605. At this time, the fixed plate 604 no longer abuts against the storage box 601, so that the storage box 601 filled with workpieces can be taken off from the bearing frame 504, which facilitates the replacement of the storage box 601. At the same time, the fixed plate 604 fixes the storage box 601, which has strong firmness. When the storage box 601 is taken off from the bearing frame 504, the bearing frame 504 slides upward to the top end along the slide rod 502 under the action of the two second springs 706. At this time, the bearing frame 504 drives the two baffles 705 at the center to move upward to the specified position, and the baffles 705 can block the workpieces in the inclined groove, so as to avoid 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 top end, the clamping strip 701 and the pull plate 702 are re-clamped with the limiting hole 704 under the resetting action of the second tension 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.

[0046] In the process of turning, the waste falling into the chute will be blown into the storage box 601 by the blowing pipe 307, and 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 cam 506 at both ends to rotate, and the cam 506 will touch the rotating wheel 507 on both sides of the supporting frame 504 during rotation, thereby driving the supporting frame 504 to move upwards along the slide rod 502, at this time the up-down shaking of the supporting frame 504 and the storage box 601 is realized by rotating the cam 506, and the up-down shaking of the storage box 601 not only makes the waste falling into the storage box 601 fall through the through slot 602 to the ground, but also makes the workpieces in the storage box 601 shake evenly, avoiding the problem of large gap between workpieces due to uneven accumulation of workpieces, and the problem of occupying space, the slide rod 502 is fixed between the mounting block 501 and the base 503, and the two bases 503 are firmly fixed, and the supporting plate 510 between the two bases 503 supports the storage box 601, improving the stability.
