Description

Technical Field

[0001] The present invention relates to the technical field of machine tool equipment, and in particular to a lathe for producing sprockets. Background Art

[0002] In the production process of mining sprockets, the preformed sprocket blank needs to be turned into an outer circular groove after the initial forming. Since mining sprockets are usually large in size, annular chips are easily generated during circular turning. Unlike ordinary chips, annular chips have greater continuity and adhesion, and are difficult to fall off naturally. In the existing processing flow, these annular chips will remain in the outer circular groove of the sprocket and can only be removed manually after the processing is completed. This not only increases the labor cost and time cost, but the residual annular chips will affect the accuracy and quality of subsequent processing, resulting in the sprocket's size deviation or surface roughness not meeting the requirements. If not discovered and cleaned in time, in the subsequent processing steps, the annular chips may damage the tool, shorten the tool life, and increase production costs.

[0022] Reference Figure 1~Figure 5According to an embodiment of the present invention, a lathe for sprocket production is proposed, which is used for turning the outer circular groove of a sprocket blank 1, comprising a machine tool 2; a clamping member 3 is rotatably arranged on the machine tool 2, and the clamping member 3 is used to fix the sprocket blank 1; a slide 4 is slidably arranged on the machine tool 2, and after sliding, it approaches or moves away from the clamping member 3; a turning tool seat 5 is slidably arranged on the slide 4, and the sliding direction is perpendicular to the sliding direction of the slide 4; a chip collecting rack 6 is slidably arranged on the slide 4, and the sliding direction of the chip collecting rack 6 is opposite to the sliding direction of the turning tool seat 5, and the chip collecting rack 6 has a chip collecting chamber 7; a first rotating wheel 8 and a second rotating wheel 9 are both rotatably arranged on the chip collecting rack 6, and the rotation directions of the first rotating wheel 8 and the second rotating wheel 9 are opposite, the first rotating wheel 8 is used to roll and abut against the outer circular groove of the bolt blank, and a first conveying interval 801 is formed between the first rotating wheel 8 and the second rotating wheel 9, and the first conveying interval 801 has a first conveying entrance 802 and a first conveying outlet 803, and the first conveying outlet 803 leads to the chip collecting chamber 7.

[0023] In this embodiment, during turning, the clamping member 3 fixes the sprocket blank 1 and drives it to rotate, and the slide 4 moves to adjust the position of the tool holder 5 for turning. The generated annular chips are rolled into the first conveying entrance 802 by the rotating first wheel 8, and under the reverse rotation of the first wheel 8 and the second wheel 9, they pass through the first conveying interval 801 and enter the chip collection chamber 7 from the first conveying outlet 803. The design of the first wheel 8 can actively roll in the annular chips, ensuring that the chips will not be missed in the outer circular groove of the sprocket blank 1, and effectively avoiding the adverse effects of chip residue on the subsequent processing accuracy and quality. The reverse rotation of the first wheel 8 and the second wheel 9 forms a stable conveying force, so that the annular chips can quickly and smoothly pass through the first conveying interval 801 into the chip collection chamber 7, greatly improving the efficiency of chip collection. This rolled-in chip collection structure can handle chips in a timely manner without waiting for manual cleaning after the processing is completed, significantly shortening the processing cycle and greatly improving production efficiency. Because the chips can be cleaned in real time, the friction and collision of the chips on the tool during the processing is reduced, the wear of the tool is reduced, and the service life of the tool is extended, thereby reducing the frequency and cost of tool replacement. It avoids scratches, bumps and other damages to the sprocket surface caused by improper operation when cleaning the chips after processing, effectively ensuring the appearance integrity and performance stability of the sprocket product. The roll-in structure is compact and works well with other parts of the lathe. It does not take up too much extra space and does not interfere with the normal turning process, ensuring the continuity and stability of the processing.

[0024] Furthermore, the chip collection rack 6 also has a conveying chamber 601, and the conveying chamber 601 has a chip feed channel 602 on one side close to the clamping member 3, and also includes a third wheel member 10. The third wheel members 10 are arranged in pairs and are slidably arranged on the upper and lower sides of the chip feed channel 602, and the third wheel members 10 are configured to move closer to or away from each other after sliding, and a second conveying interval 1001 is formed between the two third wheel members 10, and the first conveying interval 801 leads to the second conveying interval 1001 through the first conveying outlet 803.

[0025] In this embodiment, during the turning process, the annular chips are drawn in from the first rotating wheel 8, passing through the first conveying interval 801 and the first conveying outlet 803 and entering the second conveying interval 1001. According to the size of the sprocket blank 1, the third rotating wheel member 10 slides to adjust the spacing to adapt to the conveying of chips of different sizes. The arrangement of the third rotating wheel member 10 and the second conveying interval 1001 further ensures the stable conveying of the annular chips and avoids blockage or falling during the conveying process. The slidably adjustable third rotating wheel member 10 can adapt to sprocket blanks and chips of different sizes, thereby improving the versatility and flexibility of the device. The conveying path of the chips is optimized, so that the chips can enter the chip collecting chamber 7 more smoothly, thereby improving the reliability of chip collection.

[0026] Furthermore, it also includes a fourth wheel member 11, which is arranged in pairs and is slidably arranged on the upper and lower sides of the chip feed channel 602 respectively, and the fourth wheel members 11 are configured to move closer to or away from each other after sliding, and a third conveying interval 1101 is formed between the two fourth wheel members 11, and the spacing of the third conveying interval 1101 is smaller than the second conveying interval 1001.

[0027] In this embodiment, during turning, the annular chips pass through the first conveying interval 801, the second conveying interval 1001 in sequence, and finally enter the third conveying interval 1101. According to the size and shape of the chips, the third wheel member 10 and the fourth wheel member 11 slide and adjust the spacing accordingly to ensure smooth conveying of the chips. The setting of the third conveying interval 1101 provides a more refined conveying channel for annular chips of different sizes and shapes, and improves the adaptability of chip conveying. The third conveying interval 1101, which has a spacing smaller than the second conveying interval 1001, can better control smaller chips to prevent them from offsetting or jamming during the conveying process. The slidably adjustable third wheel member 10 and the fourth wheel member 11 can flexibly change the conveying interval according to the actual turning conditions to ensure the smoothness and stability of chip conveying. The design of the multi-stage conveying interval effectively reduces the risk of chips blocking the conveying channel and improves the reliability of the entire chip conveying system.

[0028] Furthermore, it also includes a first elastic member 19, which is arranged in pairs. One end of each first elastic member 19 acts on the side wall of the conveying cavity 601, and the other end acts on the third rotating wheel member 10 to provide a force for the two third rotating wheel members 10 to slide towards each other.

[0029] In this embodiment, during the turning process, the first elastic member 19 always applies a force to the third wheel member 10 to bring them closer to each other. When encountering larger chips, the third wheel member 10 overcomes the elastic force of the first elastic member 19 and moves away from each other to accommodate the chips to pass through; after the chips pass through, the first elastic member 19 urges the third wheel member 10 to move closer to each other and return to their original positions. The provision of the first elastic member 19 enables the third wheel member 10 to adapt to chips of different sizes, thereby improving the smoothness and stability of chip transportation. The ability to automatically adjust the spacing of the third wheel member 10 reduces the tediousness of manual adjustment and improves production efficiency. The ability to automatically adjust the spacing of the third wheel member 10 reduces the tediousness of manual adjustment and improves production efficiency. The impact on the conveying system caused by changes in chip size is reduced, thereby extending the service life of the equipment.

[0030] Furthermore, the chip collection chamber 7 has a chip collection entrance 701, and also includes a tail conveying wheel 20, which is rotatably arranged in the conveying chamber 601, and the tail conveying wheel 20 is located on one side of the chip collection entrance 701; the sliding top piece 12 is horizontally slidably arranged on the side wall of the conveying chamber 601, and a tail conveying space 1201 is formed between the sliding top piece 12 and the tail conveying wheel 20, the third conveying interval 1101 leads to the tail conveying space 1201, and the tail conveying space 1201 leads to the chip collection entrance 701.

[0031] In this embodiment, the annular chips generated by turning pass through each conveying interval in turn and enter the tail conveying space 1201. The tail conveying wheel 20 rotates and cooperates with the sliding top member 12 to push the chips to the chip collection entrance 701, so that they enter the chip collection chamber 7. The combination of the tail conveying wheel 20 and the sliding top member 12 ensures that the chips can enter the chip collection chamber 7 stably and orderly, avoiding jamming or blockage in the final stage of transportation. The formed tail conveying space 1201 provides a transition for the chips to enter the chip collection chamber 7, making the conveying of chips smoother. It can further improve the efficiency and reliability of chip collection and reduce the residue of chips during the conveying process. The sliding design of the sliding top member 12 can adapt to chips of different flow rates and sizes, enhancing the adaptability of the system.

[0032] Furthermore, the third rotating wheel component 10 has a second wheel portion 1002, the fourth rotating wheel component 11 has a third wheel portion 1102, and also includes an aligning roller 13. The aligning roller 13 is rotatably arranged between the third conveying interval 1101 and the tail conveying space 1201. The rotation axes of the first rotating wheel 8, the second rotating wheel 9, the second wheel portion 1002, and the third wheel portion 1102 are all the same and are parallel to the sliding direction of the slide 4. The rotation axis of the aligning roller 13 is vertical, and an aligning interval 1301 is formed between the aligning roller 13 and the inner wall of the conveying chamber 601.

[0033] In this embodiment, the chips generated by turning are transported by each rotating wheel to the trimming interval 1301. The trimming roller 13 rotates to sort and guide the chips so that they enter the tail conveying space 1201 more neatly. The setting of the trimming roller 13 can sort the conveyed chips so that they are arranged more regularly, which is convenient for the subsequent smooth entry into the tail conveying space 1201. It effectively avoids the chips from being confused and entangled during the conveying process, and ensures the continuity and stability of the chip conveying. It improves the efficiency of the chips entering the tail conveying space 1201 and reduces the problem of conveying blockage caused by the confusion of chips. It helps to maintain the smooth operation of the entire chip conveying system, reduce the occurrence of failures, and improve the working reliability of the lathe.

[0034] Furthermore, the side wall of the conveying chamber 601 has a vertical first strip guide groove 603 and a horizontal second strip guide groove 604, the fourth rotating wheel member 11 located above has a first sliding portion 1103, the first sliding portion 1103 is lifted and slidably arranged in the first strip guide groove 603, the sliding top member 12 has a second sliding portion 1202, the second sliding portion 1202 is slidably arranged in the second strip guide groove 604, and also includes a first connecting rod 14, one end of the first connecting rod 14 is hinged to the first sliding portion 1103, and the other end is hinged to the second sliding portion 1202, the first rotating wheel 8 is configured to, after lifting and sliding, drive the second sliding portion 1202 to slide in a direction close to the neat interval 1301 through the first connecting rod 14.

[0035] In this embodiment, when the chips are still in the folded and rolled state after entering the neat interval 1301, the fourth rotating wheel member 11 above is lifted and slid, and the sliding top member 12 is driven to slide in the direction close to the neat interval 1301 through the first connecting rod 14. The sliding top member 12 contacts the folded and rolled chips, applies a thrust to open them, and restores them to a relatively flat state for subsequent smooth transportation and collection. The sliding top member 12 can handle the special situation of the chips being folded and rolled, ensure the smoothness of chip transportation, and avoid the transportation channel being blocked by the folded chips. The adaptability of the entire chip processing system to chips of different shapes is improved, and transportation failures caused by abnormal chip shapes are reduced. There is no need for manual intervention to handle the folded and rolled chips, which saves labor costs and improves production efficiency. The chip sorting effect is further optimized, so that the chips can enter the subsequent transportation and collection links more neatly and orderly.

[0036] Furthermore, it also includes a swing claw 15, which is swingably set on the sliding top member 12, and the swing axis of the swing claw 15 is along the vertical direction; a reset torsion spring 16 is set on the rotating axis of the swing claw 15, providing a force for the swing claw 15 to swing toward the direction close to the trim interval 1301.

[0037] In this embodiment, during normal operation, the reset torsion spring 16 causes the swing claw 15 to always have a tendency to swing toward the direction of the neat interval 1301. When there are folded and curled chips that need to be processed, the sliding top member 12 slides forward, and the swing claw 15 first contacts the chips, and temporarily swings backward under the resistance of the chips. When the chips pass through, the reset torsion spring 16 causes the swing claw 15 to reset quickly, assisting in opening and sorting the chips. The setting of the swing claw 15 enhances the processing capability of folded and curled chips, and improves the effect and efficiency of opening the chips. The reset torsion spring 16 ensures that the swing claw 15 can be reset in time and continue to function, ensuring the continuity and stability of the processing.

[0038] Furthermore, the chip collecting rack 6 also has a transmission chamber 605, which is located on one side of the conveying chamber 601. The rotating shaft of the tail conveying wheel 20 passes through the chip collecting rack 6 and extends into the transmission chamber 605. It also includes a first gear 17, which is arranged on the rotating shaft of the tail conveying wheel 20. The second gear 18 is rotatably arranged on the inner wall of the transmission chamber 605. The second gear 18 is meshed with the first gear 17, the first rotating wheel 8 is connected to the first gear 17 by transmission, and the second rotating wheel 9 is connected to the second gear 18 by transmission.

[0039] In this embodiment, during the turning process, the first rotating wheel 8 rotates, and the first gear 17 is driven to rotate by rolling abutment transmission, and the first gear 17 drives the second gear 18 meshing therewith to rotate, thereby realizing the rotation of the second rotating wheel 9. At the same time, the rotation of the first gear 17 drives the tail conveying wheel 20 to rotate, and cooperates to complete the conveying of chips. The linkage of multiple rotating wheels and the tail conveying wheel 20 is realized, the separate driving source is reduced, the equipment structure is simplified, and the cost is reduced. The rotation coordination between each rotating wheel and the tail conveying wheel 20 is guaranteed, and the efficiency and stability of chip conveying are improved. The transmission structure is compact, and the internal space of the chip collecting frame 6 is fully utilized without affecting the operation of other components.

[0040] Furthermore, the second wheel portion 1002 , the third wheel portion 1102 and the tail conveying wheel 20 each have a plurality of teeth 1302 in the circumferential direction.

[0041] In this embodiment, the presence of the tooth portion 1302 increases the friction and gripping force between the component and the chips, ensuring that the chips will not slip or stagnate during the conveying process, thereby improving the reliability of the conveying. It can more effectively handle chips of different shapes and sizes, and enhance the adaptability of the conveying system to complex chips. It helps to improve the conveying speed and efficiency of the chips, so that the chips can be conveyed to the chip collection chamber 7 faster.
