Description

Technical Field

[0001] This application relates to the field of CNC lathe technology, and in particular to a multi-station CNC lathe. Background Technology

[0002] CNC lathes are key equipment in machining. After casting, castings usually need to undergo turning, milling, drilling or boring processes to meet the complex structure of the workpiece surface.

[0003] Currently, when machining complex workpieces, to improve machining efficiency, a dual-spindle system is typically used to clamp and rotate the workpiece, in conjunction with a multi-station power turret for finishing. For long workpieces, different or the same type of machining is often required at different positions along the axial direction. However, the traditional method of using multiple turrets side-by-side on the same side means that a turret that has completed its machining task cannot pass over a turret that is currently in operation, resulting in low machining flexibility and failure to fully utilize multiple turrets. Summary of the Invention

[0004] To improve machining flexibility and make full use of multiple multi-station power turrets, this application provides a multi-station CNC lathe.

[0005] The technical solution for a multi-station CNC lathe provided in this application is as follows:

[0006] A multi-station CNC lathe includes a lathe worktable and multiple multi-station power turrets, and also includes:

[0007] The guide rail is set on the lathe worktable. The length direction of the guide rail is parallel to the length direction of the workpiece after clamping. The guide rail corresponds one-to-one with the multi-station power turret. The arrangement direction of the multiple guide rails is perpendicular to the length direction of the guide rail. The multiple guide rails are located on the same side of the workpiece.

[0008] A sliding seat, which corresponds one-to-one with a guide rail, and the sliding seat is slidably mounted on the corresponding guide rail;

[0009] A rotating seat, which corresponds one-to-one with a sliding seat, wherein the rotating seat on the guide rail near the workpiece is mounted on the corresponding sliding seat, and the rotating seat on the guide rail away from the workpiece is mounted on the corresponding sliding seat in a vertical direction, and the multi-station power turret is slidably mounted on the rotating seat of the corresponding guide rail.

[0010] The first driving member corresponds to a sliding seat and is used to drive the corresponding sliding seat to slide.

[0011] The second driving component is used to drive the rotating seat on the guide rail away from the workpiece to rotate.

[0012] The third driving component corresponds one-to-one with the multi-station power turret and is used to drive the corresponding multi-station power turret to move.

[0013] Preferably, the multi-station power turret is provided with two slidable guide rails on the side away from the workpiece, and the sliding direction of the guide rails on the side away from the workpiece is parallel to the arrangement direction of the multiple guide rails. The lathe workpiece is provided with a fourth driving component for driving the guide rails on the side away from the workpiece to slide.

[0014] Preferably, a baffle is slidably provided on the multi-station power turret on the guide rail near the workpiece. The baffle moves circumferentially along the corresponding cutter disc on the multi-station power turret. The multi-station power turret on the guide rail near the workpiece is provided with an adjusting member for adjusting the movement of the baffle.

[0015] Preferably, the adjusting component includes a transmission ring, a transmission gear, and a transmission rack. The transmission ring is rotatably mounted on a multi-station power turret on a guide rail near the workpiece. The transmission ring is concentrically mounted with the cutter disc on the corresponding position of the multi-station power turret. The baffle is connected to the transmission ring. The transmission gear is coaxially connected to the transmission ring. The transmission rack is mounted on a multi-station power turret on a guide rail away from the workpiece and is used to mesh with the transmission gear.

[0016] Preferably, the transmission rack is located above the transmission gear, and the baffle is located between the two multi-station power turrets.

[0017] Preferably, the length direction of the transmission rack is parallel to the sliding direction of the multi-position power turret at the corresponding guide rail, and two transmission racks are arranged opposite each other along the center line of the corresponding multi-position power turret.

[0018] Preferably, the transmission gear is rotatably mounted on the corresponding rotating seat, and a telescopic rod is provided between the transmission gear and the transmission ring. The telescopic direction of the telescopic rod is parallel to the sliding direction of the multi-position power turret at the corresponding guide rail.

[0019] Preferably, the rotating seat on the guide rail near the workpiece is provided with a support, the transmission gear is rotatably mounted on the support, and an anti-slip layer is provided between the support and the transmission gear to increase the resistance to the rotation of the transmission gear.

[0021] Preferably, the cross-section of the rotating seat is rectangular, and the sliding direction of the multi-station power turret is parallel to the length direction of the corresponding rotating seat.

[0022] In summary, this application includes the following beneficial technical effects:

[0023] During machining, two spindles clamp and fix the two ends of the workpiece and drive the workpiece to rotate. A first drive unit moves the sliding seat on the guide rail closest to the workpiece to a position aligned with the workpiece for the longest machining time. The tool on the multi-station power turret on the guide rail closest to the workpiece then performs machining. Meanwhile, the multi-station power turret on the guide rail furthest from the workpiece performs machining on other parts of the workpiece. When the multi-station power turret on the guide rail furthest from the workpiece has finished machining, and it needs to be adjusted to the other side of the currently operating multi-station power turret for continued machining, a second drive unit drives the rotating seat on the guide rail furthest from the workpiece to rotate, aligning the corresponding rotating seat with its length direction parallel to the length direction of the guide rail. Then... The first driving component on the guide rail away from the workpiece drives the corresponding sliding seat to move the corresponding multi-station power turret, thus enabling it to pass over the multi-station power turrets working on the same side without interference or affecting the machining. After the multi-station power turret on the guide rail away from the workpiece moves to the required position, the second driving component drives the corresponding rotating seat to rotate, and then the third driving component adjusts the position of the multi-station power turret on the guide rail away from the workpiece, so that the workpiece can continue to be machined. This allows the turret that has completed the machining task to continue machining over the turrets working on the same side when using multiple turrets, which helps to improve machining flexibility and make fuller use of multiple multi-station power turrets.

[0028] The following combination Figures 1-3 This application will be described in further detail.

[0029] This application discloses a multi-station CNC lathe. (Refer to...) Figure 1 and Figure 2The multi-station CNC lathe includes a lathe worktable 1, a multi-station power turret 2, a guide rail 3, a sliding seat 4, a rotating seat 5, a first drive unit 6, a second drive unit 7, and a third drive unit 8. Multiple multi-station power turrets 2 are provided to form multiple workstations. Each multi-station power turret 2 adopts a 12-station or 16-station turret design, and each multi-station power turret 2 integrates turning tools, milling cutters, drills, or boring tools as needed. Specifically, the multi-station power turret 2 is existing technology, and its structure and principle will not be elaborated here. To further meet the machining needs of complex workpieces, the multi-station power turret 2 body can be designed with an up-and-down telescopic structure using hydraulic cylinders to adjust the height of the tool disc on the multi-station power turret 2.

[0030] Reference Figure 1 and Figure 2 The guide rail 3 corresponds one-to-one with the multi-station power turret 2. Multiple guide rails 3 are set on the lathe worktable 1. The length direction of each guide rail 3 is parallel to the length direction of the workpiece after clamping. The arrangement direction of multiple guide rails 3 is perpendicular to the length direction of the guide rail 3. Multiple guide rails 3 are located on the same side of the workpiece being processed, which makes the space compact and facilitates the layout of the circuit and chip removal.

[0031] Reference Figure 1 and Figure 2 The sliding seat 4 corresponds one-to-one with the guide rail 3. The sliding seat 4 is slidably disposed within the corresponding guide rail 3, and the sliding direction of the sliding seat 4 is parallel to the length direction of the corresponding guide rail 3. The cross-section of the sliding seat 4 is designed as a dovetail or T-shape to prevent the sliding seat 4 from detaching from the corresponding guide rail 3. The rotating seat 5 corresponds one-to-one with the sliding seat 4. The rotating seat 5 on the guide rail 3 closer to the workpiece is fixedly disposed on the corresponding sliding seat 4, while the rotating seat 5 on the guide rail 3 farther from the workpiece is rotatably disposed on the corresponding sliding seat 4 in the vertical direction. The multi-station power turret 2 is slidably disposed on the rotating seat 5 of the corresponding guide rail 3. Specifically, the cross-section of the rotating seat 5 is rectangular, and the sliding direction of the multi-station power turret 2 is parallel to the length direction of the corresponding rotating seat 5. When the multi-station power turret 2 is in the machining state, the length direction of the corresponding rotating seat 5 is perpendicular to the length direction of the guide rail 3.

[0032] Reference Figure 1 and Figure 2 The first driving component 6 corresponds one-to-one with the sliding seat 4. The first driving component 6 is set on the guide rail 3 and is used to drive the corresponding sliding seat 4 to slide. The second driving component 7 is set on the sliding seat 4 on the guide rail 3 away from the workpiece and is used to drive the corresponding rotating seat 5 to rotate. The third driving component 8 corresponds one-to-one with the multi-station power turret 2. The third driving component 8 is set on the corresponding rotating seat 5 and is used to drive the corresponding multi-station power turret 2 to move.

[0033] During machining, two spindles clamp and fix the two ends of the workpiece and drive the workpiece to rotate. The first drive unit 6 drives the sliding seat 4 on the guide rail 3 near the workpiece to move to the position where the workpiece is aligned for a longer machining time. The tool on the multi-station power turret 2 on the guide rail 3 near the workpiece is used to machine the workpiece, while the multi-station power turret 2 on the guide rail 3 away from the workpiece is used to machine other positions of the workpiece.

[0034] When the multi-station power turret 2 on the guide rail 3 away from the workpiece finishes machining, and needs to be adjusted to the other side of the working multi-station power turret 2 for continued machining, the second drive component 7 drives the rotating seat 5 on the guide rail 3 away from the workpiece to rotate, rotating the corresponding rotating seat 5 so that its length direction is parallel to the length direction of the guide rail 3. Then, the first drive component 6 on the guide rail 3 away from the workpiece drives the corresponding sliding seat 4 to move the multi-station power turret 2, thus enabling it to pass over the working multi-station power turret 2 without interference or affecting the machining. After the multi-station power turret 2 on the guide rail 3 on one side of the workpiece moves to the required position, the corresponding rotating seat 5 is driven to rotate by the second driving component 7, and the corresponding multi-station power turret 2 is rotated to a position close to the workpiece. Then, the position of the multi-station power turret 2 on the guide rail 3 on the side away from the workpiece is finely adjusted by the third driving component 8, so that the workpiece can continue to be processed. In the case of using multiple turrets, the multi-station power turret 2 that has completed the processing task can continue to process over the multi-station power turret 2 that is currently working, which helps to improve processing flexibility and make fuller use of multiple multi-station power turrets 2.

[0035] Reference Figure 1 and Figure 2 To facilitate the sliding of the sliding seat 4 along the corresponding guide rail 3, the first driving component 6 includes a first rodless cylinder installed within the guide rail 3. The sliding seat 4 is fixedly connected to the moving part of the first rodless cylinder within the corresponding guide rail 3. In other embodiments, the first driving component 6 can also employ a combination of a motor and a screw. The motor is mounted on the guide rail 3, and the screw is rotatably disposed within the guide rail 3 and coaxially fixed with the corresponding motor. The sliding seat 4 is threadedly connected to the corresponding screw. The combination of the motor and the screw can also drive the sliding seat 4 to slide along the corresponding guide rail 3.

[0036] Reference Figure 1 and Figure 2 To facilitate the rotation of the rotating seat 5 on the guide rail 3 away from the workpiece, the second driving component 7 includes a geared motor. The geared motor is fixedly mounted on a sliding seat 4 on the guide rail 3 away from the workpiece. In other embodiments, the geared motor may also be embedded in the sliding seat 4 on the guide rail 3 away from the workpiece, and the rotating seat 5 on the guide rail 3 away from the workpiece is fixed to the output shaft of the corresponding geared motor. In other embodiments, the geared motor may be replaced by a servo motor, stepper motor, or electric motor, etc.

[0037] Reference Figure 1 and Figure 2 To facilitate the sliding of the multi-station power turret 2 as needed, the third driving component 8 includes a second rodless cylinder, which is embedded in the corresponding sliding seat 4. The multi-station power turret 2 is fixedly connected to the moving part of the corresponding second rodless cylinder. In other embodiments, the second rodless cylinder can also be replaced by a rodless electric cylinder, hydraulic cylinder, etc.

[0038] Reference Figure 1 and Figure 2 Specifically, there are two multi-station power turrets 2, which can save costs while meeting processing requirements; the guide rail 3 on the side closer to the workpiece is fixed on the lathe worktable 1 by bolts, while the guide rail 3 on the side farther from the workpiece is slidably mounted on the lathe worktable 1. The sliding direction of the guide rail 3 on the side farther from the workpiece is parallel to the arrangement direction of the multiple guide rails 3. The lathe worktable 1 is provided with a fourth driving component 9 for driving the guide rail 3 on the side farther from the workpiece to slide.

[0039] Reference Figure 1 and Figure 2 To facilitate the sliding of the guide rail 3 on the side away from the workpiece, the fourth driving component 9 includes a third rodless cylinder embedded in the lathe worktable 1. Two third rodless cylinders are arranged opposite each other along the centerline of the guide rail 3, and the guide rail 3 on the side away from the workpiece is fixedly connected to the moving parts of the two third rodless cylinders. In other embodiments, the third rodless cylinder can also be replaced by a hydraulic cylinder, an electric cylinder, etc. To improve machining automation, the first rodless cylinder, the second rodless cylinder, the third rodless cylinder, the geared motor, and the two multi-station power turrets 2 are all electrically connected to an external CNC system.

[0040] When it is necessary to adjust the position of the multi-station power turret 2 on the guide rail 3 away from the workpiece to pass over the multi-station power turret 2 on the guide rail 3 close to the workpiece, the third rodless cylinder is activated. The third rodless cylinder drives the corresponding guide rail 3 to move away from the workpiece, thereby providing space for the two multi-station power turrets 2 to be misaligned. When the multi-station power turret 2 on the guide rail 3 away from the workpiece moves to the required position in the workpiece axis, the third rodless cylinder drives the corresponding guide rail 3 to move closer to the workpiece, thereby making it possible for the tool to process the workpiece and reduce the length of the rotating seat 5.

[0041] Reference Figure 2 and Figure 3To avoid the cross-influence of chip splashing between the two multi-station power turrets 2 during machining, a baffle 10 is slidably installed on the multi-station power turret 2 on the guide rail 3 near the workpiece. The baffle 10 moves circumferentially along the cutter head of the corresponding multi-station power turret 2. The baffle 10 is used to adjust between the two multi-station power turrets 2. The multi-station power turret 2 on the guide rail 3 near the workpiece is provided with an adjusting component for adjusting the movement of the baffle 10.

[0042] Reference Figure 2 and Figure 3 To facilitate adjustment of the position of the baffle 10, the adjusting components include a transmission ring 11, a transmission gear 12, and a transmission rack 13. The transmission ring 11 is rotatably mounted on the multi-station power turret 2 near the workpiece guide rail 3. Specifically, multiple Z-shaped connecting rods 17 are fixed on the body of the multi-station power turret 2 near the workpiece guide rail 3. The transmission ring 11 is rotatably sleeved on the multiple connecting rods 17. The transmission ring 11 is located outside the cutter head of the corresponding multi-station power turret 2 and is concentrically set with the cutter head of the corresponding multi-station power turret 2. The baffle 10 is fixedly connected to the transmission ring 11. The baffle 10 is arc-shaped and protrudes outward in a direction away from the center of the transmission ring 11 to facilitate blocking chip splashing.

[0043] Reference Figure 2 and Figure 3 The transmission gear 12 is coaxially connected to the transmission ring 11. The transmission rack 13 is fixed on the multi-station power turret 2 body on the guide rail 3 on the side away from the workpiece. The length direction of the transmission rack 13 is parallel to the length direction of the corresponding rotating seat 5, so that the length direction of the transmission rack 13 is parallel to the sliding direction of the multi-station power turret 2 at the corresponding guide rail 3. The transmission rack 13 is used to mesh with the transmission gear 12.

[0044] When the rotating seat 5 on the guide rail 3 away from the workpiece rotates until its own length direction is parallel to the length direction of the guide rail 3, the length direction of the transmission rack 13 is perpendicular to the rotation axis of the transmission gear 12, and the transmission rack 13 is aligned with the transmission gear 12. As the sliding seat 4 on the guide rail 3 away from the workpiece slides, the multi-station power turret 2 on the guide rail 3 away from the workpiece passes over another multi-station power turret 2. The transmission rack 13 can drive the transmission gear 12 to rotate, so that the transmission gear 12 drives the baffle 10 to rotate through the transmission ring 11 until the transmission rack 13 disengages from the transmission gear 12. At this time, the transmission gear 12 rotates 180 degrees, so that the baffle 10 is located on the other side of the corresponding multi-station power turret 2. That is, the baffle 10 is still located between the two multi-station power turrets 2, and continues to block the cross-influence of chips.

[0045] Reference Figure 2 and Figure 3In other embodiments, the adjusting component can also employ a combination of a micro motor, gears, and a gear ring. Specifically, the micro motor is fixedly mounted on the multi-station power turret 2 body on the guide rail 3 near the workpiece. The gear is coaxially fixed with the output shaft of the micro motor. The gear ring is rotatably mounted on the corresponding multi-station power turret 2 body, meshing with the gear ring. The baffle 10 is fixedly connected to the gear ring. By driving the gear ring to rotate through the micro motor, the position of the baffle 10 can also be adjusted according to the position of the multi-station power turret 2 on the guide rail 3 away from the workpiece.

[0046] Reference Figure 2 and Figure 3 The transmission rack 13 is located above the transmission gear 12, so that when the multi-station power turret 2 on the guide rail 3 away from the workpiece passes another multi-station power turret 2, the baffle 10 can be adjusted from above to the other side through the cooperation of the transmission rack 13, the transmission gear 12 and the transmission ring 11, so as to prevent chips and coolant from falling onto the baffle 10.

[0047] Reference Figure 2 and Figure 3 Two transmission racks 13 are arranged opposite each other along the centerline of the corresponding multi-station power turret 2, so that the transmission racks 13 and transmission gears 12 can be aligned regardless of whether the rotating seat 5 on the guide rail 3 on the side away from the workpiece rotates clockwise or counterclockwise to be parallel to the guide rail 3.

[0048] Reference Figure 2 and Figure 3 A support 15 is fixedly installed on the rotating seat 5 on the guide rail 3 near the workpiece. The support 15 is located on the side of the corresponding multi-station power turret 2 away from the workpiece. The transmission gear 12 is rotatably mounted on the support 15 via the rotating shaft 16, thereby supporting the transmission gear 12. Multiple telescopic rods 14 are provided between the transmission gear 12 and the transmission ring 11. The multiple telescopic rods 14 are arranged at intervals along the circumference of the transmission gear 12. The extension and retraction direction of the telescopic rods 14 is parallel to the sliding direction of the multi-station power turret 2 at the corresponding guide rail 3. The transmission gear 12 is rotatably mounted on the support 15 so that the position of the transmission gear 12 on the corresponding rotating seat 5 does not change, and it can better cooperate with the transmission rack 13. Through the setting of the telescopic rods 14, the transmission gear 12 can adapt to the movement of the multi-station power turret 2 on the corresponding guide rail 3. That is, the transmission gear 12 and the transmission ring 11 can rotate synchronously, but the transmission ring 11 can slide relative to the transmission gear 12. Furthermore, when the multi-station power turret 2 on the guide rail 3 away from the workpiece is in a preset position away from the workpiece, after the corresponding rotating seat 5 rotates, the transmission rack 13 and the transmission gear 12 are aligned.

[0049] Reference Figure 2 and Figure 3An anti-slip layer is provided between the support 15 and the shaft 16 of the transmission gear 12. Specifically, the anti-slip layer is fixed on the shaft 16 of the transmission gear 12. The anti-slip layer is used to increase the resistance to the rotation of the transmission gear 12. The friction between the anti-slip layer and the support 15 is much greater than the weight of the baffle 10. Through the design of the anti-slip layer, the transmission gear 12, the transmission ring 11, and the baffle 10 will not rotate unnecessarily under the action of no external force, or even under processing vibration, thus ensuring the stability of the position of the baffle 10.

[0050] Reference Figure 1 and Figure 2 The bottom wall of the rotating seat 5 slides and fits against the upper surface of the guide rail 3, so that the guide rail 3 can support the rotating seat 5 on the adjacent guide rail 3, ensuring the stability of the multi-position power turret 2; in order to reduce the friction when the rotating seat 5 rotates, multiple balls can be rolled and embedded in the bottom wall of the rotating seat 5 as needed.

[0051] The implementation principle of this application embodiment is as follows: During processing, the workpiece is clamped and fixed by the two spindles on the lathe worktable 1, and the workpiece is rotated; the first driving member 6 drives the sliding seat 4 on the guide rail 3 near the workpiece to move to the position where the workpiece is processed for a longer time, while the multi-station power turret 2 on the guide rail 3 away from the workpiece processes other positions of the workpiece. The third driving member 8 on the rotating seat 5 drives the corresponding multi-station power turret 2 to approach the workpiece for processing, thereby realizing multi-station processing.

[0052] After the multi-station power turret 2 on the guide rail 3 away from the workpiece has finished machining, when it is necessary to machine the workpiece located on the other side of the working multi-station power turret 2, the third drive member 8 on the guide rail 3 away from the workpiece drives the corresponding multi-station power turret 2 to move away from the workpiece, so that the tool is disengaged from the workpiece, until the multi-station power turret 2 moves to a preset position away from the workpiece, preparing for the engagement of the transmission rack 13 and the transmission gear 12. Then, the fourth drive member 9 drives the guide rail 3 away from the workpiece to move away from the workpiece, so that the guide rail 3 away from the workpiece is misaligned with the rotating seat 5 near the workpiece. Then, the second drive member 7 drives the rotating seat 5 on the guide rail 3 away from the workpiece to rotate, so that the length direction of the corresponding rotating seat 5 is parallel to the length direction of the guide rail 3. Then, the first drive member 6 on the guide rail 3 away from the workpiece drives the corresponding sliding seat 4 to move the multi-station power turret 2, so that it gradually passes over the working multi-station power turret 2. In this process, the transmission rack 13 meshes with the transmission gear 12. The movement of the transmission rack 13 drives the transmission gear 12 and the transmission ring 11 to rotate, moving the baffle 10 to the other side of the corresponding multi-station power turret 2. When the multi-station power turret 2 on the guide rail 3 away from the workpiece moves to the required position, the second drive 7 drives the corresponding rotating seat 5 to rotate, so that the corresponding multi-station power turret 2 rotates to be close to the workpiece. The fourth drive 9 drives the guide rail 3 on the side away from the workpiece to move towards the direction of being close to the workpiece, so that the corresponding multi-station power turret 2 is close to the workpiece. Then, the third drive 8 on the guide rail 3 on the side away from the workpiece is used to fine-tune the position of the corresponding multi-station power turret 2, so that the workpiece can continue to be processed. In the case of using multiple turrets, the multi-station power turret 2 that has completed the processing task can continue to process over the multi-station power turret 2 that is working, without interference, effectively improving the processing flexibility and making full use of the multiple multi-station power turrets 2.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
