Description

Technical Field

[0001] This invention belongs to the field of intelligent manufacturing equipment technology, specifically relating to a multifunctional intelligent multi-spindle CNC lathe. Background Technology

[0002] In the field of machining, CNC lathes are widely used as important processing equipment in the production of various metal parts. However, traditional CNC lathes have many problems in actual use. The loading and unloading process largely relies on manual operation, which is not only labor-intensive but also difficult to operate. For heavier bars and tubular parts awaiting processing, manual loading is prone to accidents, posing significant safety hazards. Simultaneously, metal shavings generated during processing tend to accumulate on the lathe's worktable, affecting subsequent processing operations and interfering with the loading and unloading process, increasing cleanup workload. Furthermore, traditional CNC lathes cannot detect the weight of the product during loading and unloading, making it difficult to understand the initial state of the product to be processed and the weight loss after processing, hindering effective control of product quality. These problems, to a certain extent, restrict the processing efficiency and quality of CNC lathes, failing to meet the demands of modern production for efficient, safe, and intelligent processing equipment.

[0003] The methods described in this section are not necessarily methods that had been previously conceived or adopted. Unless otherwise specified, no method described in this section should be assumed to be prior art simply because it is included in this section. Similarly, unless otherwise specified, the issues mentioned in this section should not be considered to be accepted in any prior art. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned problems in the prior art and provide a multi-functional intelligent multi-spindle CNC lathe. This CNC lathe improves processing efficiency through the collaborative work of multiple spindles, reduces manpower consumption, reduces operating difficulty, reduces safety issues related to manual loading, facilitates the collection of metal scraps during processing, and can detect the weight of the product during loading and unloading to understand the initial weight of the product to be processed and the weight loss of the product after processing, thereby determining the product's qualification status.

[0005] To achieve the above objectives, one technical solution adopted by the present invention is:

[0006] A multi-functional intelligent multi-spindle CNC lathe, comprising:

[0007] A lathe base, the upper end of which has an assembly groove, and the assembly groove has a slide extending to the left and right.

[0008] The first main shaft is located on one side of the extension direction of the slide table;

[0009] The second spindle is coaxial with the first spindle and its position can be adjusted along the axial direction.

[0010] A processing mechanism is located behind the slide table;

[0011] The loading and unloading mechanism includes:

[0012] A drive mechanism, which is located in the assembly slot, is capable of adjusting the telescopic length in the longitudinal direction;

[0013] A lifting component, located above the drive mechanism;

[0014] A force sensor is disposed between the drive mechanism and the lifting component;

[0015] The slide rod has two sets, which are distributed at intervals and both extend longitudinally through the slide table;

[0016] A support member comprising a front plate and a rear plate hinged to each other, the rear plate being inclined from front to back and from bottom to top and fixed to the rear sliding rod;

[0017] The sliding rod on the front side can slide upwards to abut against the lower end of the front plate;

[0018] When the drive mechanism is at the first telescopic length, the front slide bar slides down to the lower end due to gravity and abuts against the lifting member, while the upper end does not abut against the front plate. The front plate and the rear plate slide down to abut against the slide table due to gravity, so that the included angle formed by the front plate and the rear plate on the upper side is greater than or equal to degrees, and there is a gap between the rear slide bar and the lifting member.

[0019] When the drive mechanism is in the second telescopic length, the lifting member abuts against the rear slide bar, and the front slide bar is pushed to abut against the slide bar by the lifting member, causing the front plate to tilt from front to back and from top to bottom.

[0020] The lathe base's mounting slots and slides provide a stable mounting foundation and support rails for each component; the first and second spindles clamp and rotate the product, with the second spindle's axial adjustment adapting to products of different lengths; the machining mechanism completes the product processing operations; the loading and unloading mechanism's drive mechanism, lifting components, force sensors, slide rods, and support components work together, and by switching the drive mechanism's different extension lengths, the support components' states change, completing the auxiliary loading and unloading of products. The force sensor can also detect the product's weight during lifting. The overall structure ensures that the lathe achieves auxiliary loading and unloading, product rotation drive, and machining functions, reducing labor consumption and operational difficulty, and improving safety.

[0021] Furthermore, when the drive mechanism is at its second telescopic length, the included angle formed by the front plate and the rear plate on the upper side allows the inscribed cylindrical axes of the front and rear plates to connect with the axis of the first spindle in a vertical plane. This design ensures that the support axis of the product to be processed on the support member is in the same vertical plane as the axis of the first spindle, ensuring that the product to be processed can be accurately aligned with the first spindle during the lifting process. This provides a guarantee for the precise clamping of the product by each spindle, improves the accuracy and reliability of product clamping, and ensures the precision of subsequent processing.

[0022] Furthermore, the front side of the slide has an inclined surface that slopes downwards from front to back, parallel to the rear plate. When the drive mechanism is at its first extension length, both the front plate and the rear plate abut against the inclined surface. The inclined surface provides a stable support surface for the front and rear plates in their initial state, ensuring that they remain in a parallel inclined state. This prevents debris from remaining on the support during processing, allowing it to slide smoothly into the assembly slot for collection under gravity. It also ensures that the support is subjected to uniform force, extending the service life of the component.

[0023] Furthermore, when the drive mechanism is at its third telescopic length, the front slide bar is pushed against the front plate by the lifting component, making the upper surface of the front plate flush with the upper surface of the slide table. This state is specifically designed for loading and unloading processes. During loading, the product to be processed can smoothly roll from the front of the lathe base onto the front plate, avoiding laborious manual handling and reducing loading difficulty. During unloading, the processed product can easily roll off the flush front plate, facilitating unloading and reducing the risks associated with manual product handling, thus improving operational safety.

[0024] Furthermore, each group of slide bars comprises at least two, with each slide bar in the group spaced apart from the other side. This distribution of multiple slide bars disperses the gravitational load on the support components and the product, preventing excessive stress on a single slide bar that could deform or damage it. This enhances the structural stability of the loading and unloading mechanism during product support and lifting, ensuring a smooth and reliable loading and unloading process, and reducing product swaying or equipment malfunctions caused by uneven stress on the slide bars.

[0025] Furthermore, a first sleeve is fitted onto the outer side of each slide rod, and the lower end of the first sleeve is fixedly connected to the lifting component. The first sleeve protects the slide rod and provides precise guidance for its longitudinal sliding, ensuring a stable movement trajectory and improving the accuracy and reliability of the loading and unloading mechanism.

[0026] Furthermore, a second sleeve is fixedly connected to the lower end of the rear plate and sleeved on the outside of the rear sliding rod. The second sleeve enhances the structural strength of the connection between the rear plate and the sliding rod, preventing the rear plate from swaying when supporting the product and ensuring support stability.

[0027] Furthermore, a protective cover is fitted together with the lower end of the slide table and the bottom wall of the assembly slot, and the drive mechanism, lifting component, force sensor, and slide rod are all covered by the protective cover. The protective cover can effectively prevent metal debris and other materials generated during processing from entering the internal components, preventing the components from being contaminated, corroded, or damaged, ensuring the normal operation of each component of the loading and unloading mechanism, extending the service life of the equipment, and also playing a safety protection role.

[0028] Furthermore, the lathe base has a maintenance slot on its side that communicates with the assembly slot. The maintenance slot provides a convenient passage for the inspection and maintenance of components inside the assembly slot. Workers can inspect, repair, and replace components such as the drive mechanism and force sensor through the maintenance slot without disassembling the lathe base, reducing maintenance difficulty, saving maintenance time, improving equipment maintenance efficiency, and ensuring long-term stable operation of the equipment.

[0029] Furthermore, the lathe base is equipped with a sealing element for closing the maintenance slot. During normal operation of the equipment, the sealing element effectively prevents metal debris from escaping from the maintenance slot, thus ensuring stable collection of metal debris.

[0030] The present invention has at least the following beneficial effects:

[0031] Improved machining stability: The multi-spindle collaborative working mode allows multiple spindles to simultaneously clamp both ends of the product, thereby improving rotational stability and thus improving machining quality.

[0032] Reduced labor costs and operational complexity: The automated loading and unloading mechanism enables efficient product loading and unloading, reducing manual handling and significantly lowering labor costs. Furthermore, during loading, the drive mechanism is adjusted to the third telescopic length, allowing the product to roll smoothly onto the front plate. Similarly, during unloading, the third telescopic length is adjusted to facilitate product unloading, further reducing operational complexity.

[0033] Improved safety: It avoids potential safety accidents during manual handling of heavy products, reduces safety issues associated with manual material loading, and ensures the personal safety of operators.

[0034] Product weight detection: During the loading and unloading process, the force sensor can detect the initial weight of the product to be added and the weight of the processed product. This allows the control system to record weight data, understand the product processing loss, and judge the product's qualification status based on the loss, which is beneficial for effective control of product processing quality.

[0035] Facilitates chip collection: During processing, the loading and unloading mechanism is in its first telescopic length state, with the front and rear plates tilted parallel to each other. This prevents chips from accumulating and allows them to slide into the assembly slot under gravity for collection. This facilitates unified collection and processing of chips, maintaining a clean working environment for the lathe. Simultaneously, because the support components do not accumulate metal chips during processing, they do not interfere with the unloading of the product or the loading of the next cycle, ensuring stable support for the product and preventing additional weight from affecting weight measurement data.

[0036] The structure is stable and reliable: By rationally designing components such as the slide bar, first sleeve, and second sleeve, the stability and accuracy of the loading and unloading mechanism are ensured. Meanwhile, the protective cover protects internal components and extends the equipment's service life. The inclusion of inspection slots and enclosures facilitates equipment inspection and maintenance. The multi-spindle linkage control design ensures the stability and precision of the machining process. Attached Figure Description

[0046] Lathe base 1, assembly slot 11, protective cover 111, slide table 12, inspection slot 13, sealing component 14, inclined plane 121, first spindle 2, second spindle 3, machining mechanism 4, loading and unloading mechanism 5, drive mechanism 51, lifting component 52, force sensor 53, slide rod 54, first sleeve 541, second sleeve 542, support component 55, front plate 551, rear plate 552. Detailed Implementation

[0047] The invention will now be further described with reference to the accompanying drawings.

[0048] Reference Figures 1-7 As shown, a multifunctional intelligent CNC lathe of this embodiment includes a lathe base 1, a first spindle 2, a second spindle 3, a machining mechanism 4, and a loading and unloading mechanism 5.

[0049] In this embodiment, the lathe base 1 serves as the basic support component of the entire CNC lathe. Its upper end has an assembly groove 11, which is used to install and accommodate some of the lathe's functional components, providing a stable mounting base for each component. The assembly groove 11 contains left-right extending slides 12, which provide support and a moving track for the product's machining and loading / unloading processes, ensuring the product's positional accuracy during machining.

[0050] In this embodiment, the first spindle 2 is located on one side of the extension direction of the slide table 12. The main function of the first spindle 2 is to clamp and drive the product to rotate, providing rotational power for the processing of the product. During the processing, the first spindle 2 can drive the product to rotate at a set speed, cooperating with the processing mechanism 4 to complete the cutting and other processing operations on the product.

[0051] In this embodiment, the second spindle 3 is coaxially opposite to the first spindle 2 and its position can be adjusted axially. The second spindle 3 works in conjunction with the first spindle 2 to clamp both ends of the product, ensuring the stability of the product during processing. By adjusting the position of the second spindle 3 axially, it can adapt to the clamping requirements of products of different lengths, improving the versatility of the lathe.

[0052] In this embodiment, the machining mechanism 4 is located behind the slide table 12. The machining mechanism 4 is the core component for processing the product. Specifically, it can be configured with a structure with a variety of cutting tools, which can perform various machining operations such as turning, boring, and drilling on the rotating product according to the processing requirements, so as to obtain the required product shape and dimensional accuracy.

[0053] In this embodiment, the loading and unloading mechanism 5 includes a drive mechanism 51, a lifting component 52, a force sensor 53, a slide bar 54, and a support component 55.

[0054] In this embodiment, the drive mechanism 51 is located within the assembly slot 11 and can adjust its telescopic length longitudinally. As the power source for the loading / unloading mechanism 5, the drive mechanism 51 provides power for the lifting movement of the lifting component 52. By adjusting its telescopic length, it controls the position of the lifting component 52, thereby achieving changes in the state of the support component 55 and the lifting of the product. The drive mechanism 51 can employ common linear drive devices such as hydraulic cylinders, pneumatic cylinders, or electric push rods, and its telescopic movement is controlled by a control system.

[0055] In this embodiment, the lifting component 52 is located above the drive mechanism 51. Driven by the drive mechanism 51, the lifting component 52 moves up and down. Its function is to transmit the power of the drive mechanism 51 to the slide bar 54, thereby changing the state of the support component 55 by pushing the slide bar 54, and simultaneously achieving the lifting and lowering operation of the product. The lifting component 52 is typically made of a rigid metal sheet or profile to ensure that it does not deform significantly under stress.

[0056] In this embodiment, a force sensor 53 is located between the drive mechanism 51 and the lifting component 52. The main function of the force sensor 53 is to detect the weight of the product during the lifting process. When the drive mechanism 51 drives the lifting component 52 to lift the product, the force sensor 53 can sense the weight of the product and transmit the detected force signal to the control system. The control system calculates the weight of the product based on the force signal. By detecting the weight of the product during the loading and unloading process, the control system can record the initial weight of the product to be added and the weight of the processed product, thereby understanding the loss during product processing and determining the product's qualification status.

[0057] In this embodiment, there are two sets of slide rods 54, which are spaced apart and extend longitudinally through the slide table 12. The slide rods 54 connect the lifting member 52 and the support member 55. The lifting movement of the lifting member 52 is transmitted to the support member 55 through the slide rods 54, causing a change in the state of the support member 55. Simultaneously, the slide rods 54 extend longitudinally through the slide table 12, which guides the movement of the slide rods 54, ensuring that the slide rods 54 can slide stably up and down longitudinally.

[0058] In this embodiment, the support member 55 includes a front plate 551 and a rear plate 552 hinged together. The rear plate 552 slopes from front to back and from bottom to top and is fixedly connected to the rear slide rod 54. The support member 55 is the component that directly supports the product. The front plate 551 and the rear plate 552 are hinged together, and the angle between them can be changed according to the movement of the slide rod 54 to adapt to different working requirements. The rear plate 552 is fixedly connected to the rear slide rod 54, so that the movement of the rear slide rod 54 can directly drive the movement of the rear plate 552.

[0059] In this embodiment, the front slide bar 54 can slide upward to abut against the lower end of the front plate 551. When the drive mechanism 51 drives the lifting member 52 to rise, the front slide bar 54 slides upward under the push of the lifting member 52. When it slides to a certain position, it abuts against the lower end of the front plate 551, thereby pushing the front plate 551 to rotate and changing the tilt state of the front plate 551.

[0060] In this embodiment, when the drive mechanism 51 is at the first telescopic length, the front slide bar 54 slides down to its lower end under gravity and abuts against the lifting member 52, while its upper end does not abut against the front plate 551. The front plate 551 and the rear plate 552 slide down to abut against the slide table 12 under gravity, so that the included angle formed by the front plate 551 and the rear plate 552 on the upper side is greater than or equal to 180 degrees, and there is a gap between the rear slide bar 54 and the lifting member 52. The first telescopic length is the initial state, which is also the state maintained by the loading and unloading mechanism 5 during metal processing. In this state, the tilted state of the front plate 551 and the rear plate 552 can prevent debris from staying on the support member 55, and facilitate the debris to slide down into the assembly groove 11 for collection under gravity.

[0061] In this embodiment, when the drive mechanism 51 is at its second telescopic length, the lifting member 52 abuts against the rear slide bar 54, and the front slide bar 54 is pushed against the front plate 551 by the lifting member 52, causing the front plate 551 to flip and tilt from front to back and from top to bottom. In this state, the front plate 551 is tilted, which, together with the rear plate 552, can stably support the product to be added, preparing it for subsequently lifting the product to be added to align with the main shaft.

[0062] In this embodiment, when the drive mechanism 51 is at its second telescopic length, the included angle formed by the front plate 551 and the rear plate 552 on the upper side allows the inscribed cylindrical axes of the front plate 551 and the rear plate 552 to be coplanar with the axis of the first main shaft 2 in the vertical direction. This structural design allows the support axis of the product to be added on the support member 55 to be connected to the axis of the first main shaft 2 in a vertical plane, so that during the lifting process, the product to be added can be accurately aligned with the first main shaft 2 and the second main shaft 3, facilitating the main shaft to clamp the product.

[0063] In this embodiment, the front side of the slide table 12 has an inclined surface 121 that slopes downwards from front to back. The inclined surface 121 is parallel to the rear plate 552. When the drive mechanism 51 is in the first telescopic length, both the front plate 551 and the rear plate 552 abut against the inclined surface 121 in parallel. The inclined surface 121 provides a stable support surface for the front plate 551 and the rear plate 552 in the first telescopic length state, ensuring that the front plate 551 and the rear plate 552 can maintain a parallel inclined state, further improving the chip removal effect. At the same time, the parallel structural design also makes the support member 55 more evenly stressed in this state, extending the service life of the component.

[0064] In this embodiment, when the drive mechanism 51 is in the third telescopic length, the front slide bar 54 is pushed to abut against the lifting member 52, causing the upper surface of the front plate 551 to flip up to be flush with the upper surface of the slide table 12. The third telescopic length state is mainly used for loading and unloading processes. At this time, the upper surface of the front plate 551 is flush with the upper surface of the slide table 12, and the product to be processed placed on the front side of the lathe base 1 can roll smoothly onto the front plate 551, reducing the difficulty of loading. During the unloading process after processing, the drive mechanism 51 is adjusted to the third telescopic length, which makes it easier for the processed product to roll off the support member 55, reducing the difficulty of unloading and improving the safety of operation.

[0065] In this embodiment, each group of slide bars 54 consists of at least two slide bars 54, with the slide bars 54 in each group spaced apart from each other. The spaced distribution of multiple slide bars 54 makes the support member 55 more stable during the loading process, avoiding deformation or damage due to excessive force on a single slide bar 54, and ensuring the smoothness of the loading and unloading process.

[0066] In this embodiment, a first sleeve 541 is fitted on the outer side of each slide rod 54, and the lower end of the first sleeve 541 is fixedly connected to the lifting member 52. The first sleeve 541 serves to protect and guide the slide rod 54, preventing the slide rod 54 from directly rubbing against other components and wearing during sliding. At the same time, it ensures that the slide rod 54 can slide stably along the axial direction of the first sleeve 541, thereby improving the accuracy and reliability of the slide rod 54's movement.

[0067] In this embodiment, a second sleeve 542 is fixedly connected to the lower end of the rear plate 552 and sleeved on the outside of the rear slide rod 54. The second sleeve 542 connects the rear plate 552 and the rear slide rod 54 together, so that the movement of the rear slide rod 54 can be accurately transmitted to the rear plate 552, and at the same time, it can also improve the connection strength between the rear plate 552 and the rear slide rod 54.

[0068] In this embodiment, a protective cover 111 is fitted together at the lower end of the slide table 12 and the bottom wall of the assembly groove 11. The drive mechanism 51, lifting component 52, force sensor 53, and slide rod 54 are all covered by the protective cover 111. The protective cover 111 provides protection, preventing metal shavings and other substances generated during processing from entering the interior of the drive mechanism 51, lifting component 52, force sensor 53, and slide rod 54, thus avoiding contamination and damage to these components, ensuring the normal operation of the loading and unloading mechanism 5, and extending the service life of the equipment.

[0069] In this embodiment, the lathe base 1 has a maintenance slot 13 on its side that communicates with the assembly slot 11. The maintenance slot 13 provides a convenient passage for the inspection and maintenance of the components inside the assembly slot 11. Workers can use the maintenance slot 13 to inspect, repair and replace components such as the drive mechanism 51 and the force sensor 53 without having to disassemble the entire lathe base 1, which reduces the difficulty of maintenance and improves maintenance efficiency.

[0070] In this embodiment, the lathe base 1 is equipped with a sealing member 14 for closing the maintenance slot 13. During normal operation of the equipment, the sealing member 14 closes the maintenance slot 13 to prevent metal debris from being discharged through the maintenance slot 13, so as to stably store the metal debris; when maintenance is required, the sealing member 14 can be opened to carry out maintenance operations, which is convenient to use.

[0071] The working process of this multi-functional intelligent CNC lathe is as follows:

[0072] Loading Process: Initially, the drive mechanism 51 is at its first extension length. When loading is required, the control system controls the drive mechanism 51 to extend to its third extension length, at which point the upper surface of the front plate 551 is flush with the upper surface of the slide table 12. The operator places the product to be processed on the front side of the lathe base 1 and then pushes the product onto the front plate 551. Afterward, the control system controls the drive mechanism 51 to adjust to its second extension length, tilting the front plate 551 to stably support the product with the rear plate 552. Next, the drive mechanism 51 continues to extend, lifting the support member 55 and the product through the lifting member 52 and the slide rod 54 until both ends of the product are aligned with the first spindle 2 and the second spindle 3. Simultaneously, the force sensor 53 detects the weight of the product and transmits it to the control system for recording. Then, the two ends of the product are held in place by the three-jaw chucks of the first spindle 2 and the second spindle 3. After loading is complete, the drive mechanism 51 returns to its first extension length to allow for the removal of debris during processing.

[0073] Processing procedure: The control system controls the first spindle 2 and the second spindle 3 to rotate the product to be processed, while simultaneously controlling the processing mechanism 4 to perform processing operations on the product according to the set program. Metal chips generated during processing slide along the inclined front plate 551 and rear plate 552 into the assembly groove 11, realizing automatic chip collection.

[0074] Unloading Process: After processing, the control system controls the drive mechanism 51 to move, causing the support member 55 to rise and support the processed product. Then, the three-jaw chucks of the first spindle 2 and the second spindle 3 release, and the force sensor 53 detects the product weight again, transmitting the data to the control system to understand the product's processing loss and pass / fail status. Afterward, the control system controls the drive mechanism 51 to adjust to the third extension length, bringing the product into contact with the lathe base 1. The product is then rolled forward, causing it to roll off the support member 55, completing the unloading process. After unloading, the drive mechanism 51 returns to the first extension length, awaiting the next processing cycle.

[0075] It is worth mentioning that during the processing, the support component 55 does not accumulate metal shavings, so it will not interfere with the unloading of the product or the loading of the next cycle of products, ensuring that the product can be stably supported by the support component 55, and at the same time, it will not generate additional weight that affects the weight detection data.

[0076] During equipment operation, if it is necessary to inspect or repair components such as the drive mechanism 51 and force sensor 53 inside the assembly slot 11, the operator can open the sealing part 14 and perform the inspection or repair operation through the inspection slot 13. After the inspection or repair is completed, the sealing part 14 can be closed. Chip removal can be performed simultaneously while the sealing part 14 is open.

[0077] In summary, the multifunctional intelligent multi-spindle CNC lathe provided by this invention, through its reasonable structural design, enables assisted loading and unloading of products, reduces labor consumption and operational difficulty, improves operational safety, and simultaneously achieves chip collection and timely detection of product weight, thus possessing high practicality and promotional value.
