Description

Technical Field

[0001] This application belongs to the field of servo turret gear plate locking technology, specifically relating to a gear plate locking small hole buffer structure. Background Technology

[0002] The CNC servo turret is a core component of a lathe machining center. It is driven by a servo motor, which drives the tool head to rotate via gear transmission. The tool head locking and positioning is achieved through a precision three-tooth disc (fixed tooth disc, moving tooth disc, and locking tooth disc). The disengagement and engagement of the three tooth discs are hydraulically driven. In order to ensure the cutting force during the machining process, the hydraulic pressure during tooth disc locking is very high, which causes the three tooth discs to be subjected to a large impact during the locking process. Over time, this will affect the accuracy of the servo turret. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0010] A throttling device is adjustablely installed in the throttling oil circuit. The throttling device is used to adjust the connection gap between the auxiliary oil circuit and the disconnection main oil circuit.

[0011] In one feasible implementation, the gear disc locking hole buffer structure further includes:

[0012] A fixed gear plate is mounted on the housing.

[0013] The movable gear plate is located on the side of the fixed gear plate away from the housing, and the movable gear plate is coaxial with the fixed gear plate.

[0014] The drive gear meshes with the moving gear disk, and drives the moving gear to rotate.

[0015] The locking gear plate is connected to the main shaft and is located on the side of the moving gear plate away from the fixed gear plate. The locking gear plate is used to lock the fixed gear plate and the moving gear plate.

[0016] In one feasible implementation, the gear disc locking hole buffer structure further includes:

[0017] The first oil chamber is connected to the first oil passage;

[0018] The second oil chamber is connected to the second oil passage and is also connected to the first oil chamber.

[0019] The piston is movably mounted inside the housing. The piston is in contact with the locking gear plate and can move synchronously with the locking gear plate to disconnect the second oil chamber from the first oil chamber.

[0020] In one feasible implementation, the first oil circuit and the second oil circuit constitute a disengagement oil inlet channel. Oil returns through the disengagement oil inlet channel, causing the locking gear to move in the first direction and lock the locking gear. Oil enters through the disengagement oil inlet channel, pushing the locking gear to move in the second direction and loosening the locking gear.

[0021] The second direction is opposite to the first direction.

[0022] In one feasible implementation, the gear disc locking hole buffer structure further includes:

[0023] The locking oil inlet channel is opened, and oil enters the locking oil inlet channel, pushing the locking gear plate to move in the first direction to lock the locking gear plate; the locking oil inlet channel returns oil, causing the locking gear plate to move in the second direction to loosen the locking gear plate.

[0024] In one feasible implementation, the gear disc locking hole buffer structure further includes:

[0025] The connecting notch is located at the end of the piston away from the locking gear plate, so that a return oil passage is formed between the first oil chamber and the first oil passage, and the first oil chamber and the first oil passage are kept connected.

[0026] In one feasible implementation, after the connecting notch enters the first oil chamber, the piston disconnects the second oil chamber from the second oil passage.

[0034] In one feasible implementation, the adjusting member is threadedly connected to the throttling oil circuit, and a locking member is threadedly connected to the adjusting member, which fits against the housing.

[0035] The toothed disc locking hole buffer structure of this application has the following advantages compared with the prior art:

[0036] The gear disc locking hole buffer structure provided in this application embodiment includes a disengagement main oil circuit, an auxiliary oil circuit, a first oil circuit, a second oil circuit, a pressure switch, a throttling oil circuit, and a throttling device. When the gear disc needs to be locked, hydraulic oil returns from the first and second oil circuits. After the hydraulic oil passes through the first oil circuit, the pressure switch moves under the pressure of the hydraulic oil, cutting off the return path of the first oil circuit, so that the hydraulic oil can only flow out from the second oil circuit and the disengagement main oil circuit. At this time, the cross-sectional area of ​​the hydraulic oil return channel is large, and it is in the rapid return stage, which is the first stage of the gear disc locking stroke; when When the gear disc reaches the latter part of its locking stroke, the hydraulic oil only flows back from the first oil circuit. From the first oil circuit, the hydraulic oil flows back to the auxiliary oil circuit. Under the pressure of the hydraulic oil, the pressure switch moves, blocking the second oil circuit. This forces the hydraulic oil in the auxiliary oil circuit to enter the disengagement main oil circuit through the throttling oil circuit, and then flow out from the disengagement main oil circuit. Due to the throttling device, the cross-sectional area of ​​the hydraulic oil return channel is smaller at this point, and the return speed is slower. The throttling oil circuit and the throttling device reduce the return speed in the latter part of the gear disc locking stroke, which helps to reduce the impact during gear disc locking. The throttling device is adjustable in the throttling oil circuit. By adjusting the position of the throttling device, the cross-sectional area of ​​the hydraulic oil return channel in the latter part of the gear disc locking stroke can be adjusted, allowing the gear disc locking impact force to be adjusted according to actual usage conditions, making it highly practical.

[0053] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0054] like Figures 1-3As shown, according to an embodiment of this application, a geared disc locking small hole buffer structure is proposed. The geared disc locking small hole buffer structure is disposed on the housing 28. The geared disc locking small hole buffer structure includes: a disengagement main oil circuit 10, an auxiliary oil circuit 11, a first oil circuit 12, a second oil circuit 13, a pressure switch 14, a throttling oil circuit 15, and a throttling device 16; the first oil circuit 12 is connected to the auxiliary oil circuit 11; the second oil circuit 13 is connected to the disengagement main oil circuit 10 and the auxiliary oil circuit 11, and the second oil circuit 13 connects the auxiliary oil circuit 11 to the main oil circuit 10. Oil circuit 11 is connected to the disconnect main oil circuit 10; pressure switch 14 is adjustablely disposed in the second oil circuit 13, and pressure switch 14 is used to at least disconnect the circuit of the first oil circuit 12; throttling oil circuit 15 is connected to auxiliary oil circuit 11 and disconnect main oil circuit 10, and throttling oil circuit 15 connects auxiliary oil circuit 11 and disconnect main oil circuit 10; throttling device 16 is adjustablely disposed in throttling oil circuit 15, and throttling device 16 is used to adjust the connection gap between auxiliary oil circuit 11 and disconnect main oil circuit 10.

[0055] The gear disc locking hole buffer structure provided in this application embodiment includes a disengagement main oil circuit 10, an auxiliary oil circuit 11, a first oil circuit 12, a second oil circuit 13, a pressure switch 14, a throttling oil circuit 15, and a throttling device 16. When the gear disc needs to be locked, hydraulic oil returns from the first oil circuit 12 and the second oil circuit 13. After the hydraulic oil passes through the first oil circuit 12, the pressure switch 14 moves under the pressure of the hydraulic oil, cutting off the return path of the first oil circuit 12, so that the hydraulic oil can only flow out from the second oil circuit 13 and the disengagement main oil circuit 10. At this time, the cross-sectional area of ​​the hydraulic oil return channel is large, and it is in the rapid return stage, which is the first part of the gear disc locking stroke. When the gear disc reaches the latter part of the locking stroke, the hydraulic oil only flows back from the first oil circuit 12. The hydraulic oil then flows back from the first oil circuit 12 to the auxiliary oil circuit 11. The pressure switch 14 moves under the pressure of the hydraulic oil, blocking the second oil circuit 13. This forces the hydraulic oil in the auxiliary oil circuit 11 to enter the disengagement main oil circuit 10 through the throttling oil circuit 15, and then flow out from the disengagement main oil circuit 10. Due to the throttling device 16, the cross-sectional area of ​​the hydraulic oil return channel is smaller at this time, and the return speed is slower. The throttling oil circuit 15 and the throttling device 16 reduce the return speed of the gear disc during the latter part of the locking stroke, which helps to reduce the impact during gear disc locking. The throttling device 16 is adjustable within the throttling oil circuit 15. By adjusting the position of the throttling device 16, the cross-sectional area of ​​the hydraulic oil return channel during the latter part of the gear disc locking stroke can be adjusted, allowing the gear disc locking impact force to be adjusted according to actual usage conditions, making it highly practical.

[0056] Furthermore, the initial stage of the gear plate locking process involves oil return via the second oil circuit 13 and the disconnected main oil circuit 10, with a large-diameter rapid oil return to ensure the efficiency of the three-tooth plate locking. The subsequent stage of the gear plate locking process involves oil return via the first oil circuit 12 and the throttling oil circuit 15, with a small-diameter slow oil return to reduce the hydraulic oil return speed during the later stage of locking, thereby reducing the impact between the tooth surfaces during gear plate locking and improving the accuracy retention and service life of the CNC servo turret.

[0057] Furthermore, the oil supply circuit is disconnected from the hydraulic station. When oil is needed, the hydraulic station supplies oil to the disconnected main oil circuit 10. When oil needs to be returned, the hydraulic oil in the disconnected main oil circuit 10 flows back to the hydraulic station.

[0058] In some examples, such as Figure 1 As shown, the first oil circuit 12 and the second oil circuit 13 are arranged in parallel. Both the first oil circuit 12 and the second oil circuit 13 are arranged perpendicular to the disconnected main oil circuit 10. The disconnected main oil circuit 10 is arranged in parallel with the auxiliary oil circuit 11. The pressure switch 14 moves up and down in the second oil circuit 13.

[0059] like Figure 4 As shown, in one feasible embodiment, the gear plate locking hole buffer structure further includes: a fixed gear plate 24, a movable gear plate 25, a drive gear 26, and a locking gear plate 27; the fixed gear plate 24 is disposed on the housing 28; the movable gear plate 25 is disposed on the side of the fixed gear plate 24 away from the housing 28, and the movable gear plate 25 is coaxially disposed with the fixed gear plate 24; the drive gear 26 meshes with the movable gear plate 25, and the drive gear 26 drives the movable gear plate to rotate; the locking gear plate 27 is connected to the main shaft 30, and the locking gear plate 27 is disposed on the side of the movable gear plate 25 away from the fixed gear plate 24, and the locking gear plate 27 is used to lock the fixed gear plate 24 and the movable gear plate 25.

[0060] In this technical solution, the locking gear 27 locks or releases the fixed gear 24 and the moving gear 25 by its own movement. The fixed gear 24 is connected to the housing 28, and the moving gear 25 is located between the fixed gear 24 and the locking gear 27. The moving gear 25 is provided with a first external tooth, and the drive gear 26 is provided with a second external tooth. When the locking gear 27 does not lock the fixed gear 24 and the moving gear 25, the second external tooth meshes with the first external tooth, and the drive gear 26 drives the moving gear 25 to rotate, thereby realizing the indexing function of the turret. After the indexing is completed, the locking gear 27 locks the fixed gear 24 and the moving gear 25 together, thereby positioning the moving gear 25.

[0061] like Figure 2 and Figure 3As shown, in one feasible embodiment, the gear plate locking small hole buffer structure further includes: a first oil chamber 20, a second oil chamber 21, and a piston 22; the first oil chamber 20 is connected to the first oil passage 12; the second oil chamber 21 is connected to the second oil passage 13, and the second oil chamber 21 is connected to the first oil chamber 20; the piston 22 is movably disposed in the housing 28, the piston 22 is in contact with the locking gear plate 27, and the piston 22 can move synchronously with the locking gear plate 27 to disconnect the second oil chamber 21 from the first oil chamber 20.

[0062] In this technical solution, the first oil chamber 20 and the second oil chamber 21 constitute a disengagement oil chamber. When the hydraulic oil in the disengagement oil chamber enters the first oil passage 12 and / or the second oil passage 13, the pressure in the disengagement oil chamber decreases, and the piston 22 moves to the side with reduced pressure, thereby driving the locking gear 27 to move to adjust the position of the locking gear 27. When the piston 22 moves to the appropriate position, the piston 22 separates the first oil chamber 20 and the second oil chamber 21, breaking the connection between the first oil chamber 20 and the second oil chamber 21, making the first oil chamber 20 and the second oil chamber 21 independent of each other. The piston 22 blocks the oil inlet of the second oil passage 13, so that the hydraulic oil can only enter the first oil passage 12 from the first oil chamber 20, and then enter the disengagement main oil passage 10 from the throttling oil passage 15 after passing through the auxiliary oil passage 11, and then flow out from the disengagement main oil passage 10, thereby reducing the return oil speed of the gear 20 during the later stage of locking, so that the gear 20 moves slowly during the later stage of locking, reducing the impact on the gear 20.

[0063] It is understandable that the first oil chamber 20 and the second oil chamber 21 can be connected, or they can be disconnected. Whether the first oil chamber 20 and the second oil chamber 21 are connected is determined by the position of the piston 22 in the disengaged oil chamber.

[0064] like Figure 2 As shown, in one feasible implementation, the first oil passage 12 and the second oil passage 13 constitute a disengagement oil inlet channel. Oil returns through the disengagement oil inlet channel, causing the locking gear 27 to move in the first direction and lock the locking gear 27. Oil enters through the disengagement oil inlet channel, pushing the locking gear 27 to move in the second direction and loosening the locking gear 27.

[0065] The second direction is opposite to the first direction.

[0066] In this technical solution, when the locking gear 27 needs to be locked, hydraulic oil enters the disengagement inlet channel formed by the first oil circuit 12 and the second oil circuit 13 from the disengagement oil chamber. The pressure in the disengagement oil chamber decreases, and the piston 22 drives the locking gear 27 to move towards the side with lower hydraulic oil pressure, that is, the piston 22 drives the locking gear 27 to move closer to the disengagement oil chamber, thus locking the locking gear 27. When the locking gear 27 needs to be released, hydraulic oil enters the disengagement oil chamber from the disengagement inlet channel formed by the first oil circuit 12 and the second oil circuit 13. The pressure in the disengagement oil chamber increases, and the piston 22 drives the locking gear 27 to move towards the side with lower hydraulic oil pressure, that is, the piston 22 drives the locking gear 27 to move away from the disengagement oil chamber, thus releasing the locking gear 27.

[0067] like Figure 2 and Figure 5 As shown, in one feasible embodiment, the gear plate locking small hole buffer structure further includes: a locking oil inlet channel 17, through which oil is introduced to push the locking gear plate 27 to move in the first direction, thereby locking the locking gear plate 27; through which oil is returned to the locking oil inlet channel 17, the locking gear plate 27 is moved in the second direction, thereby releasing the locking gear plate 27.

[0068] In this technical solution, the locking oil inlet channel 17 works in conjunction with the disengaging oil inlet channel to ensure the flexibility and timeliness of the movement of the piston 22 and the locking gear 27. The locking oil chamber 18 and the disengaging oil chamber are located on both sides of the piston 22. When oil enters the locking oil inlet channel 17 and oil returns from the disengaging oil passage, the pressure on the piston 22 in the locking oil chamber 18 increases, pushing the piston 22 and the locking gear 27 to move in the first direction closer to the disengaging oil passage, so that the locking gear 27 is locked. When oil returns from the locking oil inlet channel 17 and oil enters from the disengaging oil passage, the pressure on the piston 22 in the disengaging oil chamber increases, pushing the piston 22 and the locking gear 27 to move in the second direction away from the disengaging oil passage, so that the locking gear 27 is released.

[0069] Furthermore, such as Figure 2 and Figure 6 The locking gear 27 is connected to the main shaft 30. The piston 22 is restricted on the main shaft 30 by the locking nut 29, allowing the piston 22 to move along the main shaft 30. The piston 22 moves under the pressure of hydraulic oil, which in turn drives the locking gear 27 to move. When hydraulic oil enters the locking oil chamber 18 through the locking oil inlet channel 17, the first oil chamber 20 and the second oil chamber 21 return oil, and the locking gear 27 moves to the left. The locking gear 27 locks the fixed gear 24 and the moving gear 25. When the three gears are locked, the locking gear 27 contacts the tooth surfaces of the fixed gear 24 and the moving gear 25, and the position of the moving gear 25 is fixed by the tooth surface strength of each gear. When the first oil chamber 20 and the second oil chamber 21 receive oil, and the locking oil chamber 18 returns oil, the locking gear 27 moves to the right, and the three gears disengage. The moving gear 25 can rotate and rotate under the transmission of the drive gear 26.

[0070] In this technical solution, when the locking gear 27 needs to be released, oil enters through the main disengagement oil circuit 10, and the hydraulic oil pushes the pressure switch 14 to move, causing the pressure switch 14 to move upward and open, so that the second oil circuit 13 and the first oil circuit 12 are connected through the auxiliary oil circuit 11. The disengagement oil chamber is simultaneously supplied with oil through the second oil circuit 13 and the first oil circuit 12, with dual oil supply, which pushes the piston 22 and the locking gear 27 to move quickly to the right. The hydraulic oil in the locking oil chamber 18 returns to the hydraulic station through the locking oil inlet channel 17, so that the locking gear 27 can be released quickly.

[0071] like Figure 3 and Figure 7 As shown, in one feasible embodiment, the toothed disc locking small hole buffer structure further includes: a connecting notch 23, which is provided at the end of the piston 22 away from the locking toothed disc 27, so that a return oil passage is formed between the first oil chamber 20 and the first oil passage 12, so that the first oil chamber 20 and the first oil passage 12 remain connected.

[0072] In this technical solution, when the locking gear 27 needs to be locked, the piston 22 drives the locking gear 27 to move to the side of the piston 22 away from the locking gear 27. During the locking process of the locking gear 27, the piston 22 gradually blocks the oil inlet of the second oil passage 13. The connecting notch 23 ensures that the return oil passage between the first oil passage 12 and the first oil channel is not blocked by the piston 22. That is, the first oil passage 12 and the first oil chamber 20 are connected through the connecting notch 23, so that when the locking gear 27 is in the later stage of locking, the hydraulic oil in the first oil chamber 20 can flow into the first oil passage 12 through the connecting notch 23 and slowly return to the throttling oil passage 15, so as to realize the slow locking of the locking gear 27, reduce the impact between the tooth surfaces of the three gears during locking, ensure the accuracy of each gear, and thus improve the accuracy retention of the turret.

[0073] like Figure 6 As shown, in one feasible implementation, after the connecting notch 23 is fully inserted into the first oil chamber 20, the piston 22 disconnects the second oil chamber 21 from the second oil passage 13.

[0074] In this technical solution, during the later stroke of locking the locking gear 27, the connecting notch 23 on the piston 22 completely enters the housing 28, and the piston 22 blocks the passage between the second oil passage 13 and the second oil chamber 21, thus disconnecting the connection between the second oil passage 13 and the second oil chamber 21.

[0075] In some examples, such as Figure 7 The piston 22 has four symmetrically arranged arc-shaped connecting notches 23, which correspond to four first oil passages 12 respectively. All four first oil passages 12 are connected to the first oil chamber 20 to ensure the timely oil output of the first oil chamber 20.

[0076] like Figure 1 As shown, in one feasible embodiment, the pressure switch 14 includes: a positioning member 141, an elastic member 142, and a sealing member 143; the positioning member 141 is disposed in the second oil passage 13 and is connected to the housing 28; the elastic member 142 is disposed in the second oil passage 13 along the length direction of the second oil passage 13, and the first end of the elastic member 142 is connected to the positioning member 141; the sealing member 143 is disposed in the second oil passage 13, and the sealing member 143 is connected to the second end of the elastic member 142, and the sealing member 143 is movable within the second oil passage 13.

[0077] In this technical solution, the positioning component 141 is installed in the second oil circuit 13 and connected to the housing 28. The positioning component 141 is used to fix the elastic component 142. The sealing component 143 is connected to the positioning component 141 through the elastic component 142, so that the sealing component 143 has the ability to automatically reset and move in the second oil circuit 13 under the pressure of hydraulic oil, ensuring the timely closing and opening of the pressure switch 14 under the action of hydraulic oil.

[0078] like Figure 1 As shown, in one feasible embodiment, the throttling device 16 includes: an adjusting member 161 and a sealing member 162; the adjusting member 161 is connected to the housing 28 and is adjustablely disposed in the throttling oil passage 15; the sealing member 162 is disposed on the outside of the adjusting member 161 along the axial direction of the adjusting member 161 and is in contact with the housing 28.

[0079] In this technical solution, the adjusting member 161 is adjustablely connected to the housing 28 to adjust the depth of the adjusting member 161 inserted into the throttling oil circuit 15, adjust the position of the adjusting member 161 in the throttling oil circuit 15, thereby adjusting the size of the return oil port of the throttling oil circuit 15 and adjusting the return oil speed; the adjusting member 161 and the housing 28 are sealed by the sealing member 162 to prevent hydraulic oil from leaking from the joint between the adjusting member 161 and the housing 28, and ensure the sealing of the throttling oil circuit 15.

[0080] Furthermore, the lower end of the adjusting component 161 is tapered. By adjusting the position of the adjusting rod up and down, the cross-sectional area of ​​the channel during the return flow of the small hole is controlled, the flow rate of the return flow of the small hole is controlled, thereby controlling the return oil speed of the later stroke and the moving speed of the locking gear 27.

[0081] like Figure 1 As shown, in one feasible embodiment, the adjusting member 161 is threadedly connected to the throttling oil passage 15, and a locking member 163 is threadedly connected to the adjusting member 161, the locking member 163 being in contact with the housing 28.

[0082] In this technical solution, the adjusting component 161 is connected to the housing 28 by threads. By turning the adjusting component 161, its position in the throttling oil circuit 15 can be changed to adjust the return oil speed. The threaded connection has good self-locking properties, which can ensure that the position of the adjusting component 161 is fixed after adjustment. By setting a locking component 163 on the adjusting component 161, the adjusting component 161 is further fixed to prevent it from loosening and to ensure that the position of the adjusting component 161 remains unchanged, which helps to keep the return speed of the throttling oil circuit 15 constant.
