Description

Technical Field

[0001] The present invention relates to the technical field of processing devices, and in particular to a cylinder boring machine and a processing system. Background Art

[0002] At present, the processing of turbine cylinder bodies is carried out by large-scale CNC gantry milling machines. During processing, the cylinder body needs to be fixed on the main shaft so that the cylinder body and the main shaft can rotate synchronously, and then it is processed by the large-scale CNC gantry milling machine. Due to the large size of the large-scale CNC gantry milling machine and the turbine cylinder body, it is inconvenient to move the cutting parts of the large-scale CNC gantry milling machine, which increases the difficulty of processing the cylinder body.

[0003] In the related art, the turbine cylinder body is usually fixed and then processed by moving the cutting assembly of the cylinder boring machine. However, the cutting assembly will contact the turbine cylinder body and generate vibration when moving, which will cause the cutting assembly to deviate from the preset processing route, thereby reducing the processing accuracy of the cutting assembly.

[0025] like Figures 1 to 5 As shown, in the first aspect, the present invention provides a cylinder boring machine, comprising a spindle 10; a cutting assembly 20, comprising a connecting seat 21 and a cutting piece 22, the connecting seat 21 is connected to the spindle 10 along the axial movement of the spindle 10, and the cutting piece 22 is connected to the connecting seat 21 along the radial movement of the spindle 10, and is configured to process a cylinder body 90; a first driving assembly 30, provided on the spindle 10, the driving end of the first driving assembly 30 is drivingly connected to the cutting piece 22, and is configured to drive the connecting seat 21 to move relative to the spindle 10 along the axial direction of the spindle 10; a second driving assembly 40, provided on the spindle 10, the driving end of the second driving assembly 40 The moving end is driven and connected to the cutting piece 22, and is configured to drive the cutting piece 22 to move radially relative to the connecting seat 21 of the main shaft 10; the third driving component 50, the driving end of the third driving component 50 is driven and connected to one end of the main shaft 10, and is configured to drive the main shaft 10 to rotate with its own central axis as the rotation axis; the guide component 60 is arranged between the main shaft 10 and the connecting seat 21, the guide component 60 includes a guide block 61 and a guide rail 62, the guide rail 62 is installed on the main shaft 10 and extends along the axial direction of the main shaft 10, the guide block 61 moves along the axial direction of the main shaft 10 and is connected to the guide rail 62, and the connecting seat 21 is installed on the guide block 61.

[0026] In this embodiment, the cylinder body 90 with a diameter of 1280 mm to 2480 mm and a length of 2800 mm can be processed with a maximum cutting amount of 8 to 15 mm.

[0027] In this embodiment, X is the radial direction of the main axis 10 , and Y is the axial direction of the main axis 10 .

[0028] The beneficial effects of the cylinder boring machine and the processing system of the present invention are: By setting up the above structure, the connecting seat 21 can slide stably along the guide rail 62 when moving axially along the main shaft 10, effectively reducing the deviation caused by the vibration generated by the contact between the cutting assembly 20 and the turbine cylinder 90, ensuring that the cutting assembly 20 can strictly follow the preset processing route, thereby significantly improving the processing accuracy. At the same time, the guide assembly 60 also provides a stable movement path for the connecting seat 21, making the cutting assembly 20 more stable during the axial movement process, while limiting the vibration generated by the contact between the cutting assembly 20 and the turbine cylinder 90 as much as possible, avoiding the cutting assembly 20 from deviating from the preset processing route due to vibration, thereby improving the stability of the processing process. Further improving the reliability and stability of the processing process.

[0029] In addition, the first drive assembly 30 drives the connecting seat 21 to move axially along the main shaft 10, the second drive assembly 40 drives the cutting piece 22 to move radially along the main shaft 10, and the third drive assembly 50 drives the main shaft 10 to rotate. Through the coordinated work of multiple drive assemblies and combined with the stable guiding effect of the guide assembly 60, the motion control of the entire cutting assembly 20 is made more precise and flexible to meet different processing requirements, thereby improving the applicability and scope of application of the cylinder boring machine.

[0030] like Figure 5 As shown, optionally, the first drive assembly 30 includes: a first motor 31, having a first drive end; a first reducer 32, connected to the first drive end; a first rotating rod 33, the outer peripheral wall of the first rotating rod 33 is provided with a first threaded structure, the connecting seat 21 has a threaded hole, the threaded structure is threadedly connected to the threaded hole, the rotation axis of the first rotating rod 33 is parallel to the axis of the main shaft 10, one end of the first rotating rod 33 is connected to the first reducer 32, and the first reducer 32 is configured to drive the first rotating rod 33 to rotate and drive the connecting seat 21 to move along the axial direction of the main shaft 10.

[0031] By setting up the above structure, the high-speed and low-torque output of the motor can be converted into low-speed and high-torque rotation of the screw, and the threaded structure is used to cooperate with the connecting seat 21 to achieve axial movement of the connecting seat 21.

[0032] In addition, the first reducer 32 can reduce the influence of the speed fluctuation of the first motor 31 on the movement of the connecting seat 21, thereby ensuring the stability of the processing process.

[0033] In this embodiment, the feeding amount of the first rotating rod 33 is 0.1-0.3 mm / revolution.

[0034] like Figure 4 As shown, optionally, the first rotating rod 33 includes a lead screw. Since the lead screw has high transmission efficiency, the driving loss of the first motor 31 can be reduced, which is beneficial to improving the driving efficiency of the device.

[0035] In this embodiment, a protective sleeve can be further installed on the outer peripheral wall of the screw to prevent foreign matter from entering the thread gap and affecting the transmission accuracy. This can extend the service life of the screw and thus reduce the cost of using the device.

[0036] Optionally, the second drive assembly 40 includes: a second motor 41 having a second drive end; a second reducer 42 connected to the second drive end; a transmission structure 43, one end of the transmission structure 43 is connected to the second reducer 42, and the other end of the transmission structure 43 is connected to the cutting member 22, and the second reducer 42 is configured to drive the cutting member 22 to move radially along the main shaft 10 through the transmission structure 43.

[0037] By providing the above structure, the rotational motion of the second motor 41 can be converted into the radial movement of the cutting member 22 along the main shaft 10, thereby enabling the processing of the annular belt of the cylinder body 90.

[0038] In addition, the second reducer 42 can reduce the influence of the speed fluctuation of the second motor 41 on the movement of the cutting member 22, thereby ensuring the stability of the machining process.

[0039] In this embodiment, the feed rate along the radial direction of the main shaft 10 is 1.5-4 mm / min.

[0040] Optionally, the transmission structure 43 includes: a second rotating rod 44, one end of the second rotating rod 44 is connected to the second reducer 42, and the rotation axis of the second rotating rod 44 is parallel to the axis of the main shaft 10; a third rotating rod 45, one end of the third rotating rod 45 is threadedly connected to the second rotating rod 44, and the other end of the third rotating rod 45 is threadedly connected to the cutting member 22, and the rotation axis of the third rotating rod 45 is perpendicular to the rotation axis of the second rotating rod 44. The second rotating rod 44 drives the third rotating rod 45 to rotate, and drives the cutting member 22 to move radially along the main shaft 10.

[0041] By controlling the threads and pitches of the second and third rotating rods 44, 45, the accuracy of radial feed can be improved. With the second rotating rod 44 parallel to the axis of the spindle 10 and the third rotating rod 45 perpendicular to the second rotating rod 44, a right-angled transmission structure 43 is formed, thus avoiding excessive axial extension and further expanding the device's applicability.

[0042] In this embodiment, a threaded structure is provided on the outer peripheral wall of the second rotating rod 44 , and the third rotating rod 45 is specifically a lead screw.

[0043] In other embodiments, the transmission structure 43 may also be replaced by a gear transmission, which can further reduce the structural complexity of the component and also facilitate maintenance of the component.

[0044] Optionally, the worm gear structure further includes: a worm wheel 46 sleeved on one end of the third rotating rod 45 , and a worm 47 coaxially sleeved on the second rotating rod 44 .

[0045] By setting the above structure, the worm gear 46 can ensure that the third rotating rod 45 rotates synchronously with the second rotating rod 44, thereby avoiding cutting offset caused by asynchronous transmission. In addition, the structure of the worm gear 46 is simple and easy to process, which not only reduces the processing difficulty of the worm gear 46, but also reduces the processing cost of the worm gear 46.

[0046] In this embodiment, the worm 47 can move axially relative to the second rotating rod 44 and can rotate simultaneously with the second rotating rod 44 .

[0047] Optionally, the cylinder boring machine further includes: a conductive member 70, which is overlapped on the other end of the spindle 10 and is electrically connected to the first motor 31 and the second motor 41 respectively; and a power distribution cabinet 80, which is electrically connected to the conductive ring to supply power to the conductive ring.

[0048] By setting the above structure, the conductive member 70 is overlapped on the end of the main shaft 10, so as to realize continuous power supply to the first motor 31 and the second motor 41 during the rotation of the main shaft 10, which can solve the risk of disconnection caused by cable entanglement, thereby improving the reliability of continuous operation of the equipment, and using the distribution cabinet 80 to supply power through the conductive member 70, it can also ensure the stability of the power supply process.

[0049] In this embodiment, the conductive member 70 is specifically a slip ring, which is overlapped on the outer peripheral wall of the main shaft 10. In this way, when the main shaft 10 rotates, the slip ring will not rotate synchronously with the main shaft 10. At the same time, it can also supply power to the first motor 31 and the second motor 41, thereby ensuring the stability of power supply.

[0050] Optionally, the third drive assembly 50 includes: a clamping member 51 for clamping and fixing one end of the spindle 10; a spindle 10 box, which is drivingly connected to one end of the spindle 10, and the spindle 10 box is configured to drive the clamping member 51 to drive the spindle 10 to rotate.

[0051] By providing the above structure, the spindle 10 can be clamped and fixed, thereby preventing the spindle 10 from shaking during the machining process and ensuring that the spindle 10 always rotates around its own precise central axis. This ensures that the motion path of the cutting member 22 remains stable when machining the cylinder body 90, reducing machining errors caused by shaking of the spindle 10. At the same time, the spindle box 10 is connected to the spindle 10 and drives its rotation, which can transmit power to the spindle 10, ensuring that the spindle 10 can maintain a constant speed and torque output under different machining conditions, making the cutting process more stable, which is conducive to improving machining quality.

[0052] Optionally, the cylinder boring machine further includes: a controller, which is communicatively connected to the first motor 31 and the second motor 41 and is configured to control the operating states of the first motor 31 and the second motor 41 .

[0053] By setting the above structure, the controller can accurately control the operating parameters of the first motor 31 and the second motor 41, so that the axial and radial movements of the cutting member 22 are synchronously and accurately executed, thereby ensuring that the cutting trajectory meets the preset requirements and avoiding processing deviations caused by human operating errors.

[0054] In a second aspect, the present invention provides a processing system, including the above-mentioned cylinder boring machine; a plurality of receiving members 100 are provided on both sides of the main shaft 10 of the cylinder boring machine in the radial direction, and the receiving members 100 are used to receive the cylinder body 90.

[0056] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
