Description

Technical Field

[0001] The present invention relates to the technical field of machine tool equipment, and specifically, to a lathe for sprocket production. Background Art

[0002] In the production process of mining sprockets, after the preformed sprocket blank is initially formed, turning processing of the outer circular groove is required. Since mining sprockets are usually large in size, annular chips are likely to be generated during annular turning. Different from ordinary chips, annular chips have greater coherence 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 remaining annular chips will affect the accuracy and quality of subsequent processing, resulting in dimensional deviation or surface roughness of the sprocket not meeting the requirements. If not discovered and cleaned in time, during subsequent processing operations, the annular chips may damage the cutting tool, shorten the service life of the cutting tool, and increase production costs. In addition, during the process of manually cleaning the annular chips, the surface of the sprocket may be scratched or knocked due to improper operation, affecting the appearance and performance of the product.

Since chips can be cleaned in real time, the friction and collision of the chips on the tool during machining are reduced, the degree of tool wear is decreased, the service life of the tool is extended, and thus the frequency and cost of tool replacement are reduced. It avoids possible scratches, knocks and other damages to the sprocket surface caused by improper operation during manual chip cleaning after machining, effectively ensuring the appearance integrity and performance stability of the sprocket product. The chip-drawing-in structure is compact and operates well in coordination with other components of the lathe, without occupying too much extra space and without interfering with the normal turning machining process, ensuring the continuity and stability of machining.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0044] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0045] Refer to Figures 1 to 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] Further, it further includes a first elastic member 19. The first elastic members 19 are 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 runner member 10, providing a force for the two third runner members 10 to slide towards each other.

[0052] In this embodiment, during the turning process, the first elastic member 19 always applies a force to the third runner member 10 to make them approach each other. When encountering larger-sized chips, the third runner member 10 overcomes the elastic force of the first elastic member 19 and moves away from each other to allow the chips to pass through; after the chips pass through, the first elastic member 19 urges the third runner member 10 to approach each other and return to the original position. The setting of the first elastic member 19 enables the third runner member 10 to adapt to chips of different sizes, improving the smoothness and stability of chip conveying. It can automatically adjust the distance between the third runner members 10, reducing the tediousness of manual adjustment and improving production efficiency. It can automatically adjust the distance between the third runner members 10, reducing the tediousness of manual adjustment and improving production efficiency. It reduces the impact on the conveying system caused by changes in chip size and extends the service life of the equipment.

[0053] Further, the chip collecting cavity 7 has a chip collecting inlet 701. It further includes a tail conveying wheel 20. The tail conveying wheel 20 is rotatably arranged in the conveying cavity 601, and the tail conveying wheel 20 is located on one side of the chip collecting inlet 701; a sliding top member 12 is horizontally slidably arranged on the side wall of the conveying cavity 601, and a tail conveying space 1201 is formed between the sliding top member 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 collecting inlet 701.

[0054] In this embodiment, the annular chips generated by turning pass through each conveying interval in sequence 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 collecting inlet 701, enabling them to enter the chip collecting cavity 7. The combination of the tail conveying wheel 20 and the sliding top member 12 ensures that the chips can enter the chip collecting cavity 7 stably and orderly, avoiding jamming or blocking in the final stage of conveying. The formed tail conveying space 1201 provides a transition for the chips to enter the chip collecting cavity 7, making the chip conveying smoother. It can further improve the efficiency and reliability of chip collection and reduce the residue of chips during conveying. The slidable design of the sliding top member 12 can adapt to chips of different flow rates and sizes, enhancing the adaptability of the system.

[0055] Further, the third rotating wheel member 10 has a second wheel portion 1002, the fourth rotating wheel member 11 has a third wheel portion 1102, and further includes a trimming roller 13. The trimming 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 trimming roller 13 is vertical, and a trimming interval 1301 is formed between the trimming roller 13 and the inner wall of the conveying cavity 601.

[0056] In this embodiment, the chips generated by turning are conveyed through each rotating wheel member and reach the trimming interval 1301. The trimming roller 13 rotates to trim and guide the chips so that they enter the tail conveying space 1201 more neatly. The arrangement of the trimming roller 13 can trim the conveyed chips, make their arrangement more regular, and facilitate their subsequent smooth entry into the tail conveying space 1201. It effectively avoids the situations of chip chaos and entanglement during the conveying process, ensures the continuity and stability of chip conveying, improves the efficiency of chips entering the tail conveying space 1201, and reduces the problem of conveying blockage caused by chip chaos. It helps to keep the entire chip conveying system running smoothly, reduces the failure rate, and improves the working reliability of the lathe.

[0057] Further, the side wall of the conveying cavity 601 has a vertical first strip-shaped guide groove 603 and a horizontal second strip-shaped guide groove 604. The fourth rotating wheel member 11 located above has a first sliding portion 1103. The first sliding portion 1103 is arranged to slide up and down in the first strip-shaped 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-shaped guide groove 604. Further 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 drive the second sliding portion 1202 to slide towards the direction close to the trimming interval 1301 through the first connecting rod 14 after sliding up and down.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] In this embodiment, during the turning process, the first runner 8 rotates, and drives the first gear 17 to rotate through rolling abutment transmission. The first gear 17 drives the second gear 18 meshing with it to rotate, thereby realizing the rotation of the second runner 9. Meanwhile, the rotation of the first gear 17 drives the tail conveyor wheel 20 to rotate, and cooperates to complete the conveying of chips. The linkage of multiple runners and the tail conveyor wheel 20 is realized, reducing the separate drive sources, simplifying the equipment structure and reducing the cost. The rotational coordination between each runner and the tail conveyor wheel 20 is ensured, improving the efficiency and stability of chip conveying. The transmission structure is compact, making full use of the internal space of the chip collecting rack 6 without affecting the operation of other components.

[0063] Furthermore, the second wheel part 1002, the third wheel part 1102 and the tail conveyor wheel 20 all have a plurality of tooth parts 1302 in the circumferential direction.

[0064] In this embodiment, the existence of the tooth part 1302 increases the friction and grasping force between the component and the chips, ensuring that the chips will not slip or stagnate during the conveying process, and improving the reliability of conveying. It can more effectively handle chips of different shapes and sizes, enhancing the adaptability of the conveying system to complex chips. It helps to improve the conveying speed and efficiency of the chips, enabling the chips to be conveyed to the chip collecting cavity 7 faster.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
