[0003] However, existing multi-station turning processing devices have significant limitations in practical applications. Most of the current equipment adopts a fixed station layout, and the transmission path of shaft parts between stations is relatively fixed, making it difficult to flexibly adjust the operation sequence and position according to the processing requirements of different parts. When shaft parts need to be switched repeatedly between multiple operating areas, it is often necessary to manually re-clamp or adjust the position of the parts in the fixture to adapt to the processing requirements of different stations.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0038] Embodiment: This embodiment provides a multi-station turning processing device for shaft parts. Refer to Figure 1 - Figure 12Specifically, it includes a base 1, a round table 2 is fixed on the top of the base 1, and a plurality of first sliding grooves 201 distributed around the round table 2 are opened, one end of the first sliding groove 201 points to the center of the round table 2, a first slide rail 202 is fixed in the first sliding groove 201, and an adjustable clamping mechanism is arranged on the first slide rail 202, the adjustable clamping mechanism includes a first slide table 3 slidably mounted on the first slide rail 202, and a chuck 301 is rotatably mounted on the top of the first slide table 3, an electric clamping claw 302 is installed on the chuck 301, a rotating table 4 is rotatably mounted at the center of the round table 2, and two second sliding grooves 401 symmetrically arranged along the central axis are opened at the edge of the rotating table 4, and a second slide rail 400 docking with the first slide rail 202 is fixed in the second sliding groove 401 2, a first servo motor 403 for driving the rotating table 4 to rotate is fixed in the round table 2, a translation mechanism located below the first slide rail 202 is arranged in the round table 2, a turning mechanism corresponding to the outer ends of the plurality of first slide grooves 201 is fixed on the round table 2, the turning mechanism comprises a lifting plate 9 slidably plugged on the top of the round table 2, a vertically arranged first electric push rod 901 is fixed in the round table 2, and the telescopic end of the first electric push rod 901 is fixedly connected to the lifting plate 9, a second electric push rod 902 perpendicular to the central axis of the chuck 301 is fixed on the lifting plate 9, and a tool holder 903 is fixed on the telescopic end of the second electric push rod 902, a turning tool 904 is fixed in the tool holder 903, and the model and size of the turning tool 904 fixed on each tool holder 903 are different.

[0039] During the operation of the device, the staff can use the device to perform turning processing on multiple shaft parts. The outer end of each first slide groove 201 corresponds to an operating area for processing shaft parts, and because the turning tools 904 fixed on each tool holder 903 are different, the steps for processing shaft parts in each operating area are different. The shaft parts are placed on each chuck 301 and are firmly clamped by the corresponding electric claws 302 set on the chuck 301. Then the chuck 301 is driven to rotate, driving the shaft parts to rotate at high speed. During the rotation process, the turning processing of the shaft parts is achieved through the contact between the turning tool 904 and the shaft parts in the corresponding operating area. During the turning process, the height of the turning tool 904 can be adjusted by driving the first electric push rod 901, and the distance between the turning tool 904 and the corresponding shaft parts can be adjusted by driving the second electric push rod 902. The operation is flexible and convenient.

[0040] Each working area corresponds to a different turning step. During the turning process of shaft parts, when it is necessary to change the working area, the staff first controls the corresponding chuck 301 to stop rotating, and then the first servo motor 403 is powered on and started to drive the rotating table 4 to rotate, so that the second slide rail 402 in the second chute 401 opened on the rotating table 4 is docked with the first slide rail 202 corresponding to the first slide table 3 that needs to transfer the working area. Then the translation mechanism is started. Driven by the translation mechanism, the first slide table 3 moves along the first slide rail 202 to the second slide rail 402. Then the first servo motor 403 drives the rotating table 4 to continue rotating, so that the second slide rail 402 loaded with the first slide table 3 is docked with the first slide rail 202 corresponding to the target working area. Driven by the translation mechanism corresponding to the target working area, the first slide table 3 drives the shaft parts on the chuck 301 to move onto the first slide rail 202 and move into the target working area, where they are subjected to different types of turning operations by the corresponding turning tool 904 in the target working area. By providing two second slide rails 402 on the rotating table 4, a temporary parking position can be provided for the first slide table 3, which is beneficial to realizing the flexible and smooth transfer operation of shaft parts in each working area, facilitating the device to sequentially perform continuous and different types of turning processing on shaft parts according to requirements, and is beneficial to improving the turning flexibility and processing efficiency of shaft parts.

[0041] In the specific implementation process, as Figure 3 and Figure 7 - Figure 9 shown, the translation mechanism includes a third slide rail 5 arranged in parallel directly below the first slide rail 202, and a second slide table 501 slides on the third slide rail 5. A screw rod 502 parallel to it is rotatably installed in the third slide rail 5. A second servo motor 503 for driving the screw rod 502 to rotate is fixed at the end of the third slide rail 5. A pin box 504 is fixed at the bottom of the first slide table 3, and a vertically arranged pin plate 505 is slidably inserted into the pin box 504. A spring 506 for elastically pulling the top of the pin plate 505 is fixed in the pin box 504. A pin slot 507 located directly below the pin plate 505 is fixed on the second slide table 501, and an electromagnet 508 is fixed in the pin slot 507. The bottom end of the pin plate 505 is arranged in an inverted trapezoidal structure, and a pressure sensor is arranged in the pin slot 507.

[0042] During the operation of the device, when the device uses the translation mechanism to drive and adjust the first sliding table 3, the electromagnet 508 installed in the pin slot 507 is powered on and starts. The pin plate 505 is made of a ferromagnetic material such as iron. After the electromagnet 508 is powered on and starts, it generates a magnetic attraction on the pin plate 505. With the help of magnetic adsorption, the pin plate 505 is pulled downward, so that the pin plate 505 is vertically inserted into the pin slot 507, making the first sliding table 3 and the second sliding table 501 form a connection. In this state, the second servo motor 503 is powered on and starts, driving the screw 502 to rotate. With the help of the threaded connection between the screw 502 and the second sliding table 501, the second sliding table 501 can be driven to move along the third slide rail 5, and then drive the first sliding table 3 to move back and forth between the first slide rail 202 and the second slide rail 402. By controlling the rotation direction of the screw 502, the direction of the reciprocating movement of the second sliding table 501 driving the first sliding table 3 can be controlled, realizing flexible control of the movement of the first sliding table 3. By setting the bottom end of the pin plate 505 as an inverted trapezoidal structure, it can enter the pin slot 507 more smoothly during the downward movement. By installing the pressure sensor in the pin slot 507, when the pin plate 505 moves downward into the pin slot 507, it can apply an extrusion force to the pressure sensor. Through the pressure sensor, the action of the pin plate 505 inserted into the pin slot 507 can be detected, which is beneficial to ensuring the accuracy of the reciprocating movement of the first sliding table 3 controlled by the translation mechanism of the device.

[0043] In the specific implementation process, as Figure 4 and Figure 7 - Figure 9 As shown, a first gear 6 rotates in the first sliding table 3, and the first gear 6 is fixedly connected to the rotating shaft of the chuck 301. One end of the first slide rail 202 away from the center of the circular table 2 is rotatably installed with a second gear 601 meshing with the first gear 6. A third servo motor 602 for driving the second gear 601 to rotate is fixed in the circular table 2. During the operation of the device, during the turning operation, the first sliding table 3 drives the shaft part clamped by the electric chuck 302 on the top of the chuck 301 to move to the operation area. In this state, the first gear 6 and the second gear 601 are meshed. The third servo motor 602 is powered on and starts, driving the second gear 601 fixed on its drive shaft to rotate. With the help of the meshing between the second gear 601 and the first gear 6, the first gear 6 is driven to drive the chuck 301 to rotate at a high speed, thereby providing stable rotational power for the turning operation of the shaft part. The second gear 601 is arranged on the side of the first gear 6 away from the center of the circular table 2, which makes the meshing between the first gear 6 and the second gear 601 not interfere with the movement of the first sliding table 3, and as long as the first sliding table 3 moves into place, the first gear 6 will necessarily mesh with the second gear 601 in the corresponding operation area, which can effectively ensure the stability and flexibility during the operation of the device.

[0044] In the specific implementation process, asFigure 4 and Figure 11 As shown in Figure 11 , an oil passage 7 is provided in the chuck 301 in a surrounding manner, and two first channels 701 are provided side by side and vertically in the rotating shaft of the chuck 301. Two annular pipes 702 are fixed in the first slide 3 and are movably sleeved on the rotating shaft of the chuck 301. The two annular pipes 702 are respectively rotationally communicated with the two first channels 701. A second channel 703 is provided in the first slide 3 and is correspondingly communicated with the two annular pipes 702. During the operation of the device, two through holes are provided on the rotating shaft of the chuck 301 in an upper and lower staggered manner, and the two through holes are respectively communicated with the two first channels 701. The two annular pipes 702 are rotationally sleeved outside the two through holes. Through the docking of the annular pipes 702 and the through holes, the rotational communication between the two annular pipes 702 and the two first channels 701 is realized. When turning a shaft-like part, the oil enters through one second channel 703. With the rotational communication between one annular pipe 702 and one first channel 701, the oil enters the oil passage 7 and flows. Then, the oil flows back into the other second channel 703 through the rotational communication between the other first channel 701 and the other annular pipe 702. With one in and one out, and continuous circulation, a tendency for the oil to circulate in the oil passage 7 provided in the chuck 301 is formed. During the turning process, the high heat generated by the shaft-like part due to turning friction is transmitted to the chuck 301 through the electric chuck 302. The heat can be quickly dissipated by means of the circulating oil, avoiding overheating of the shaft-like part during turning and affecting the turning effect.

[0045] In the specific implementation process, as Figure 4 and Figure 11 shown, a receiving groove 704 is provided at the bottom of the first slide 3, and a pressing block 705 vertically arranged on the top of the first slide rail 202 is slidably inserted in the receiving groove 704. A reed 706 for elastically supporting the top of the pressing block 705 is fixed in the receiving groove 704. An oil cavity 707 is provided in the pressing block 705, and a third channel 708 communicated with the oil cavity 707 is provided in the first slide 3. During the operation of the device, under the elastic support of the reed 706, the pressing block 705 has a tendency to move downward, so that the pressing block 705 tightly presses on the top of the first slide rail 202 to limit the position of the first slide 3, which can ensure the stability of the first slide 3 during the stop. When it is necessary to control the first slide 3 to move and adjust the position, the oil is simultaneously pressurized and injected through the two third channels 708. The oil in the third channels 708 is injected into the oil cavity 707 from bottom to top, which can drive the pressing block 705 to move upward against the elastic support of the reed 706, so that the pressing block 705 is separated from the top of the first slide rail 202, releasing the position lock of the first slide 3, facilitating the first slide 3 to be driven by the translation mechanism to move. The operation is flexible and convenient. With mutual cooperation, the stability of the device during actual use can be effectively improved.

[0046] In the specific implementation process, asFigure 11 and Figure 12 As shown, two second channels 703 and two third channels 708 are both connected side by side on the inner wall of the pin box 504. The two second channels 703 are located above the two third channels 708. An oil path switching mechanism is provided between the first slide 3 and the second slide 501. The oil path switching mechanism includes two first oil pipes 8 arranged side by side. Two connection holes 801 arranged side by side are formed on the inner wall of the other side of the pin box 504. Grooved holes 802 corresponding to the two connection holes 801 are formed in the pin plate 505, and docking holes 803 corresponding to the two second channels 703 and the two third channels 708 are formed. The two docking holes 803 are correspondingly connected to the two grooved holes 802. A connecting plate 804 is fixed on the side wall of the pin plate 505. An electric lifting table 805 located directly below the connecting plate 804 is fixed on the top of the second slide 501. Two self-sealing joints 806 arranged side by side are fixed on the connecting plate 804. A self-sealing insertion tube 807 corresponding to and communicating with the two first oil pipes 8 is fixed in the electric lifting table 805, and the self-sealing insertion tube 807 is correspondingly arranged with the self-sealing joints 806. Second oil pipes 808 are respectively connected and communicated between the two self-sealing joints 806 and the two connection holes 801.

[0047] During the operation of the device, the two first oil pipes 8 are externally connected to an oil pump for the inlet and outlet operations of the oil. During turning processing, when it is necessary to supply oil to the two second channels 703 with one inlet and one outlet, the electromagnet 508 in the pin slot 507 is powered off to release the magnetic adsorption on the pin plate 505. Driven by the elastic pulling of the spring 506, the pin plate 505 is driven to move to the upper position in the pin box 504. In this state, the two docking holes 803 are docked with the two second channels 703. Synchronously, the electric lifting table 805 rises, so that the self-sealing joint 806 is inserted into the corresponding self-sealing insertion tube 807. When the self-sealing joint 806 is inserted into the self-sealing insertion tube 807, the self-sealing joint 806 and the self-sealing insertion tube 807 are connected and communicated. The oil in one first oil pipe 8 enters one second channel 703 through one self-sealing insertion tube 807, self-sealing joint 806, second oil pipe 808, connection hole 801, grooved hole 802 and docking hole 803, flows in the oil path 7 for one circle, and then flows out through the other first oil pipe 8 after being carried by heat through the docking of the other second channel 703, docking hole 803, grooved hole 802, connection hole 801, second oil pipe 808, self-sealing joint 806 and self-sealing insertion tube 807, realizing the circulating flow of the oil in the oil path 7. In this state, the docking holes 803 are not docked with the third channels 708, and no oil is pressurized and injected into the oil cavity 707. The pressing block 705 is tightly pressed on the first slide rail 202 under the elastic support of the reed 706 to ensure the stable position of the first slide 3.

[0048] When it is necessary to move the first slide table 3, the electromagnet 508 in the pin slot 507 is powered on and activated, generating a magnetic downward pulling force on the pin plate 505. In this state, the two docking holes 803 are docked with the two third channels 708. Synchronously, the electric lifting table 805 descends, so that the self-sealing joint 806 maintains the plugging state with the corresponding self-sealing insertion tube 807. At this time, the two oil pumps are started simultaneously to pump oil into the two first oil pipes 8 at the same time. The oil enters through the two first oil pipes 8, and then passes through the corresponding self-sealing insertion tube 807, self-sealing joint 806, second oil pipe 808, connection hole 801, groove-shaped hole 802, and docking hole 803, and simultaneously enters the two third channels 708 for pressurized injection, providing power for the separation of the pressing block 705 from the top of the first slide rail 202.

[0049] After the first slide table 3 is transferred to the second slide rail 402 and before the rotating table 4 rotates, the electromagnet 508 will be powered off to release the magnetic attraction traction on the pin plate 505. In this state, the pin plate 505 moves upward under the elastic pulling of the spring 506, and the electric lifting table 805 still remains in the lower position, which causes the self-sealing joint 806 and the self-sealing insertion tube 807 to separate, interrupting the oil supply. When the self-sealing joint 806 and the self-sealing insertion tube 807 are separated, both the self-sealing joint 806 and the self-sealing insertion tube 807 are in a closed state, avoiding oil leakage. In the case of the separation of the self-sealing joint 806 and the self-sealing insertion tube 807, the first slide table 3 is driven by the rotating table 4 to rotate and move more smoothly, so that the oil delivery path will not interfere with the movement of the first slide table 3, which is beneficial to ensuring the stability during the actual operation of the device.

[0050] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
