TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent manufacturing equipment, and particularly relates to an integrated turning-milling-grinding numerical control machining machine. BACKGROUND

[0002] The turning-milling-grinding machining machine is an integrated machining equipment, which can complete turning, milling and grinding processes on the same machine tool, has the machining capacity of a lathe, a milling machine and a grinding machine, and realizes the purpose of one-time clamping of a workpiece and multi-process machining. The one-time clamping can avoid the reference error caused by multiple clamping, improve machining precision and efficiency, and is suitable for machining of precision parts such as hydraulic valve spools and aviation parts.

[0003] At present, in the prior art, when the integrated machining of the welded hollow cylinder is performed, the weld of the welded part needs to be cut first, then the cut part is milled, and finally polished. However, when the integrated machining of the hollow cylinder is performed, the frequent position adjustment during the switching of machining processes causes the clamped end of the cylinder to be repeatedly stressed, which is prone to cause damage such as indentation and deformation. Moreover, the cylinder is usually clamped on the outer surface. If the position of clamping is continuously adjusted, the clamped position is prone to be damaged, which destroys the integrity of the workpiece. Furthermore, the welded hollow cylinder is prone to axis deviation. If only the angle or position of the machining tool is adjusted, the deviation of the weld area cannot be effectively offset, which causes the machining posture of the tool and the weld to be mismatched, and the machining precision of the weld cannot be guaranteed. Therefore, the present application provides an integrated turning-milling-grinding numerical control machining machine. SUMMARY

[0006] Preferably, the compensation mechanism further comprises a spreading plate for spreading and clamping the inner surface of the hollow cylinder, the inner side of the spreading plate is rotatably connected with a first supporting rod and a second supporting rod through a pin shaft, a plurality of grooves are arranged on the surface of the spreading plate, and the outer side of the spreading plate is arranged in an arc shape.

[0007] Preferably, the inner side of the spreading plate is rotatably connected with the first supporting rod and the second supporting rod through a pin shaft, one end of the second supporting rod is rotatably connected with a sliding sleeve through a pin shaft, one end of the sliding sleeve is fixedly connected with an electric push rod, the inner side of the electric push rod is fixedly connected with a driving shaft, and the sliding sleeve is spline-connected with the driving shaft.

[0008] Preferably, one end of the first supporting rod is rotatably connected with a fixing sleeve through a pin shaft, the fixing sleeve is fixedly connected with the driving shaft, the end of the fixing sleeve away from the second supporting rod is also rotatably connected with the spreading plate through a plurality of first supporting rods, and a plum blossom groove is arranged on one end of the shell close to the spreading plate.

Furthermore, by opening the slide and slot, the hollow cylinder after positioning and clamping compensation can always maintain a stable state, improving the accuracy of the hollow cylinder during machining.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Reference Figures 1 to 5 An integrated turning, grinding, and milling CNC machining center includes a control console 1 and a support 7. A compensation mechanism 2 for initial positioning of the outer side of a hollow cylinder is provided on one side of the control console 1. The compensation mechanism 2 includes a rotatable outer shell 201. An integrated machining table 3 is provided above the support 7. An auxiliary mechanism 4 and a gain mechanism 6 are provided inside the outer shell 201 to assist in positioning the hollow cylinder. The auxiliary mechanism 4 includes an elastic telescopic rod 401 connected to the outer shell 201. An auxiliary plate 402 is fixedly connected to the lower part of the elastic telescopic rod 401. A sliding groove 403 for positioning is provided on one side of the auxiliary plate 402. A second locking plate 405 is slidably contacted inside the sliding groove 403. A drive rod 404 is fixedly connected to the side of the second locking plate 405. The gain mechanism 6 includes a rotatable rotating sleeve 607, with multiple wedges 605 fixedly connected to the inner side of the rotating sleeve 607. The inner arc surface of the wedges 605 slides in contact with a sliding column 608, and a clamping pad 609 is fixedly connected to one end of the sliding column 608. The drive rod 404 is fixedly connected to the wedges 605.

[0019] When the hollow cylinder is machined by turning, grinding and milling after welding, the auxiliary plate 402 under the multiple elastic telescopic rods 401 is in a closed state in the initial state. When the hollow cylinder needs to be placed inside the outer shell 201, the hollow cylinder needs to be pushed into the inner shell 201 from the middle position of the auxiliary plate 402. At this time, the auxiliary plate 402 will move from the inside to the outside under the pushing force of the hollow cylinder. At this time, the auxiliary plate 402 will always be in contact with the surface of the hollow cylinder under the elastic reaction force of the elastic telescopic rods 401. This can provide a certain stability for the placement of the hollow cylinder and improve the placement accuracy. It should be noted that when one end of the hollow cylinder contacts the outer shell 201, it indicates that the hollow cylinder has reached the appropriate position. At this time, the rotatable rotating sleeve 607 is activated to drive multiple wedges 605 to rotate synchronously. The rotation of the wedges 605 will push the clamping pad 609 under the sliding column 608 to move towards the surface of the hollow cylinder through the inner arc surface. After the clamping pad 609 contacts the surface of the hollow cylinder, it will position it. In conjunction with multiple auxiliary plates 402, the hollow cylinder is positioned along its axis, and the first compensation work is performed. It should be noted again that after the clamping pad 609, in conjunction with the auxiliary plate 402, performs the first positioning compensation on the hollow cylinder, the axis of the hollow cylinder is parallel to the axis of the outer shell 201. Furthermore, when the wedge block 605 rotates, it will drive the drive rod 404 to move synchronously. The movement of the drive rod 404 will cause the second clamping plate 405 to slide on one side of the auxiliary plate 402. Since multiple grooves 403 are provided on one side of the auxiliary plate 402, the second clamping plate 405 will slide inside the grooves 403. When the clamping pad 609 is fully in contact with and clamped to the outer surface of the hollow cylinder, the second clamping plate 405 will also limit the auxiliary plate 402, which can prevent the auxiliary plate 402 from shaking or loosening during subsequent rotation processing. This can effectively improve the stability of the contact between the auxiliary plate 402 and the hollow cylinder, thereby improving the stability of clamping the outer surface of the hollow cylinder. Furthermore, since the auxiliary plate 402 has a multi-layered sliding groove 403 on the side near the second clamping plate 405, when the auxiliary plate 402 and the clamping pad 609 clamp hollow cylinders of different diameters, the second clamping plate 405 driven by the drive rod 404 on one side of the wedge block 605 will slide inside the sliding groove 403 at different heights, and can effectively contact the auxiliary plate 402, thereby limiting the auxiliary plate 402 and improving the contact effect between the auxiliary plate 402 and the hollow cylinder. It should be explained that when the outer surface of the hollow cylinder comes into contact with the clamping pad 609 and the auxiliary plate 402, since the clamping pad 609 and the auxiliary plate 402 are coaxially arranged, the auxiliary plate 402 and the clamping pad 609 can stably position the hollow cylinder during the first positioning and clamping compensation. This can effectively improve the stability of the hollow cylinder during subsequent turning, grinding and milling. Furthermore, when different processes are required to process the weld seam of the hollow cylinder, different processing processes can be achieved by switching the processing tools above the integrated processing table 3, avoiding multiple clamping situations and maximizing the protection of the integrity of the outer surface of the clamped part.

[0020] Reference Figures 2 to 4 The gain mechanism 6 also includes a rotating cylinder 601 rotatably connected to the housing 201. The inner side of the rotating cylinder 601 is provided with an internal tooth 602 and an incomplete tooth 604. One side of the incomplete tooth 604 is meshed with a drive gear 603. The drive gear 603 is fixedly connected to the output end of the drive motor provided inside the control console 1. The outer side of the rotating sleeve 607 is fixedly connected with an external tooth 606, which meshes with the internal tooth 602.

[0021] During operation, in the initial state, the drive gear 603 is in the middle position of the incomplete tooth 604, such as... Figure 5 As shown, when it is necessary to drive the clamping pad 609 to move to the outer surface of the hollow cylinder, the drive motor inside the control console 1 drives the drive gear 603 to rotate. The rotation of the drive gear 603 meshes and drives the incomplete tooth 604 to rotate. The rotation of the incomplete tooth 604 drives the rotating cylinder 601 to rotate inside the outer shell 201. At this time, the rotation of the rotating cylinder 601 will drive the inner tooth 602 to mesh with the outer tooth 606, thereby driving the rotating sleeve 607 to rotate. At this time, the rotation of the rotating sleeve 607 pushes the clamping pad 609 at one end of the sliding column 608 to perform the first positioning and clamping on the surface of the hollow cylinder through the inner arc surface of the wedge block 605. It should be noted that when the clamping pad 609 no longer needs to clamp the outer surface of the hollow cylinder, the drive motor inside the control console 1 rotates in the opposite direction to drive the drive gear 603 to reverse. The reverse rotation of the drive gear 603 drives the rotating cylinder 601 to reverse through the incomplete teeth 604. The reverse rotation of the rotating cylinder 601 meshes and drives the rotating sleeve 607 on the inner side of the external teeth 606 to rotate, so that the clamping pad 609 no longer clamps the hollow cylinder, and then the hollow cylinder is taken out from the inside of the outer shell 201. It should be noted again that when the wedge 605 rotates in the opposite direction with the rotating sleeve 607, the second clamping plate 405 driven by the drive rod 404 on one side of the wedge 605 will slide out from the inside of the slide groove 403 and no longer limit the auxiliary plate 402. At this time, the hollow cylinder can be smoothly pulled out from the inside of the outer shell 201, which can prevent the hollow cylinder from tilting after losing support. At this time, the auxiliary plate 402 can support it, which facilitates the installation and disassembly of the hollow cylinder and improves processing efficiency.

[0022] Reference Figures 6 to 9 The compensation mechanism 2 also includes an expansion plate 205 for expanding and clamping the inner surface of the hollow cylinder. The inner side of the expansion plate 205 is rotatably connected to the first support rod 204 and the second support rod 206 via a pin. The surface of the expansion plate 205 is provided with multiple grooves, and the outer side of the expansion plate 205 is arc-shaped.

[0023] During operation, initially, the expansion plate 205 is not fully expanded. After the hollow cylinder is clamped and compensated for the first time by the clamping pad 609 and the auxiliary plate 402, the expansion plate 205 is driven to move towards the inner surface of the hollow cylinder. When the expansion plate 205 contacts its inner surface, it is driven to rotate. The rotation of the expansion plate 205 causes friction contact with the inner surface of the hollow cylinder through its arc-shaped outer side. At this time, the rotation of the expansion plate 205 can remove burrs and other debris from the inner surface of the hollow cylinder. When the expansion plate 205 is fully in contact with the inner surface of the hollow cylinder, it can effectively improve the integrity of the contact between the expansion plate 205 and the inner surface, allowing the expansion plate 205 to fully expand and clamp the hollow cylinder. It can work with the clamping pad 609 and the auxiliary plate 402 to clamp and position the hollow cylinder from the inside out in all directions, which can improve the stability of subsequent turning, grinding and milling of the weld position of the hollow cylinder. It should be noted that after the expansion plate 205 rubs away the burrs and other debris on the inner side of the hollow cylinder, the expansion plate 205 opens up to expand and clamp the hollow cylinder. Furthermore, the grooves on the surface of the expansion plate 205 can also prevent the appearance of protrusions on the inner side of the hollow cylinder from affecting the contact effect between the arc surface of the expansion plate 205 and the inner surface of the hollow cylinder, thus enabling the expansion plate 205 to better expand and clamp the hollow cylinder. It should be explained that when the arc surface of the expansion plate 205 contacts the inner surface of the hollow cylinder but is not yet expanded and clamped, the rotating cylinder 601 continues to rotate, thereby allowing the clamping pad 609 to fully position and clamp the outer surface of the hollow cylinder. Because the outer surface of the expansion plate 205 is already in contact with the inner surface of the hollow cylinder, even if the clamping pad 609 and the auxiliary plate 402 continue to apply force to clamp the outer surface of the hollow cylinder, the hollow cylinder will not experience axial displacement. This ensures that the outer surface of the hollow cylinder is fully positioned, effectively improving the initial positioning effect. When the expansion plate 205 subsequently expands and clamps the hollow cylinder, it can fix the position of the hollow cylinder after the initial positioning compensation, eliminating the need for multiple clamping operations and enabling effective multi-process processing.

[0024] Reference Figures 6 to 9 The inner side of the expansion plate 205 is rotatably connected to a first support rod 204 and a second support rod 206 via a pin. One end of the second support rod 206 is rotatably connected to a sliding sleeve 207 via a pin. One end of the sliding sleeve 207 is fixedly connected to an electric push rod 208. The inner side of the electric push rod 208 is fixedly connected to a drive shaft 202. The sliding sleeve 207 and the drive shaft 202 are splined.

[0025] During operation, when it is necessary to remove impurities from the inner surface of the hollow cylinder, the electric push rod 208 is activated to push the sliding sleeve 207 to slide on the surface of the drive shaft 202. At this time, the movement of the sliding sleeve 207 will push the expansion plate 205 at one end of the second support rod 206 to move towards the inner surface of the hollow cylinder through the pin. When the outer arc surface of the expansion plate 205 contacts the inner surface of the hollow cylinder and is in a working state of incomplete expansion and clamping, the electric push rod 208 will no longer push the sliding sleeve 207 to slide on the surface of the drive shaft 202. Instead, another drive motor set inside the control console 1 will drive the drive shaft 202 to rotate. At this time, the rotation of the drive shaft 202 will drive multiple expansion plates 205 to rotate synchronously. At this time, the expansion plates 205 can perform grinding work on the inner surface of the hollow cylinder, removing burrs and other defects on the inner surface, so that the outer arc surface of the expansion plate 205 can fully contact the inner surface of the hollow cylinder, which can effectively improve the stability of the expansion and clamping. It should be noted that since the sliding sleeve 207 and the drive shaft 202 are splined, the drive shaft 202 can drive the sliding sleeve 207 and the electric push rod 208 on one side to rotate synchronously. When the expansion plate 205 is in the retracted state, the hollow cylinder is placed inside the outer shell 201, and its inner wall will not interfere with the outer side of the expansion plate 205. Furthermore, when the sliding sleeve 207 drives the second support rod 206 to swing through the pin, and the second support rod 206 drives the expansion plate 205 to expand outward through the pin, the first support rod 204 below the expansion plate 205 will also swing, synchronously driving the expansion plate 205 to move outward, which can effectively improve the effect of the expansion plate 205 in expanding and clamping the hollow cylinder.

[0026] Reference Figures 6 to 9 One end of the first support rod 204 is rotatably connected to a fixed sleeve 203 via a pin. The fixed sleeve 203 is fixedly connected to the drive shaft 202. The end of the fixed sleeve 203 away from the second support rod 206 is also rotatably connected to the expansion plate 205 via multiple first support rods 204. A plum blossom groove is provided at the end of the outer shell 201 near the expansion plate 205.

[0027] During operation, when the expansion plate 205 is pushed by the second support rod 206, the multiple first support rods 204 below the expansion plate 205 will also move synchronously, thereby supporting the movement of the expansion plate 205 and realizing the expansion effect of the expansion plate 205 on the inner surface of the hollow cylinder. This allows the outer surface of the hollow cylinder to achieve positioning compensation, while the inner surface achieves fixed support, effectively improving the stability of the expansion of the hollow cylinder and improving the stability of its subsequent turning, grinding and milling processes. It should be noted that by opening a quincunx groove at one end of the outer shell 201 near the expansion plate 205, when the expansion plate 205 is supported and pushed by the second support rod 206 and multiple first support rods 204, the two ends of the expansion plate 205 will move outward in an arc trajectory, rather than moving vertically. In order to prevent one end of the expansion plate 205 from being unable to move when expanding the hollow cylinder, the expansion plate 205 has sufficient space to move. It should be explained that when the drive shaft 202 is driven to rotate by the drive motor inside the control console 1, the drive shaft 202 will also drive the fixed sleeve 203 to rotate synchronously. At this time, the fixed sleeve 203 will realize the rotation of multiple expansion plates 205 through multiple first support rods 204 and second support rods 206 rotatably connected to the surface of the sliding sleeve 207. This will enable friction to clean the burrs on the inner surface of the hollow cylinder, making it easier for the expansion plates 205 to expand it stably and avoid axial displacement. This achieves the purpose of compensating for the welded hollow cylinder, so that the integrated processing table 3 can process it according to different working conditions.

[0028] Reference Figures 6 to 9The inner surface of the outer shell 201 is slidably connected to a slide rod 209. One end of the slide rod 209 is fixedly connected to a triangular block 210. One side of the triangular block 210 is set with an inclined surface. One side of the triangular block 210 slidably contacts a first locking plate 211. The first locking plate 211 is located on one side of the slide column 608. A slot 610 is opened on the side of the slide column 608 near the first locking plate 211.

[0029] During operation, the expansion plate 205 is pushed by the second support rod 206 and multiple first support rods 204, and moves in an arc-shaped trajectory. After the expansion plate 205 moves to a designated position within the plum blossom groove, one end of the expansion plate 205 moves upward, pushing the slide rod 209 to slide inside the outer shell 201. The sliding of the slide rod 209 causes the triangular block 210 to move synchronously. The movement of the triangular block 210 pushes the first locking plate 211 to slide laterally inside the outer shell 201 via the inclined plane. When the first locking plate... After the plate 211 reaches the designated position, the first clamping plate 211 will be inserted into one of the multiple slots 610 opened on the side of the slide column 608. This can limit the slide column 608, prevent the inner arc surface of the wedge block 605 from becoming loose with the slide column 608, effectively improve the stability of the contact positioning between the clamping pad 609 below the slide column 608 and the outer surface of the hollow cylinder, prevent the gap between the clamping pad 609 and the hollow cylinder, and effectively improve the stability of the clamping pad 609 in contacting and clamping the hollow cylinder. It should be noted that after the expansion plate 205 fully expands the inner surface of the hollow cylinder, it will continue to drive the rotating cylinder 601 to rotate, thereby making the clamping pad 609 fully clamp and position the outer surface of the hollow cylinder. At this time, the sliding column 608 may move slightly downward. Since the width of the first clamping plate 211 is smaller than the width of the slot 610 on one side of the sliding column 608, after the sliding column 608 moves slightly downward, the inside of the slot 610 will fully contact the surface of the first clamping plate 211, thereby enabling the first clamping plate 211 to be stably inserted into the inside of the slot 610, improving the stability of the sliding column 608. It should be explained that when one end of the slide bar 209 is no longer subjected to the upward pressing force of the expansion plate 205, the slide bar 209 will be reset from the inside of the outer shell 201 under the action of the reset spring, so that the first clamping plate 211 is pulled out from the inside of the slot 610 and no longer limits the slide column 608. This can effectively improve the stability of limiting the lower end of the sliding column 608 clamping pad 609, so that the clamping pad 609 can always position and compensate for the hollow cylinder. It should be reiterated that the rotating cylinder 601 will only reverse after the expansion plate 205 stops expanding and clamping the inner surface of the hollow cylinder. This causes the clamping pad 609 at the lower end of the sliding column 608 to stop contacting the surface of the hollow cylinder, allowing the hollow cylinder to lose clamping force sequentially from the inside out. This effectively improves the positioning compensation effect of the hollow cylinder, effectively improves the stability of the hollow cylinder clamping, facilitates multiple processing steps, and avoids multiple clamping of the hollow cylinder.

[0030] Reference Figures 1 to 5 The slide groove 403 is arc-shaped on one side of the auxiliary plate 402, the second clamping plate 405 is arc-shaped, and the end of the second clamping plate 405 near the slide groove 403 is tapered. One side of the clamping pad 609 is slidably connected to the inner side of the outer shell 201, and a return spring is provided at the sliding position.

[0031] During operation, when the wedge 605 drives the second locking plate 405 to slide into the interior of the groove 403 via the drive rod 404, the wedge 605 moves in a circular motion trajectory. By setting the second locking plate 405 in an arc shape, the drive rod 404 can easily drive the second locking plate 405 to slide into the interior of the groove 403, thereby limiting the auxiliary plate 402. This effectively improves the stability of the auxiliary plate 402 in positioning compensation of the hollow cylinder's outer surface. Furthermore, since the end of the second locking plate 405 near the auxiliary plate 402 is tapered and the elastic telescopic rod 401 is telescopic, when one end of the second locking plate 405 slides into the interior of the groove 403, even after the second locking plate 405 contacts one side of the groove 403, the tapered surface allows the second locking plate 405 to easily slide into the interior of the groove 403, thus limiting the auxiliary plate 402. It should be noted that when the sliding column 608 drives the clamping pad 609 to perform positioning and clamping compensation on the outer surface of the hollow cylinder, the clamping pad 609 will slide on one side of the outer shell 201. When the rotating sleeve 607 reverses and no longer pushes the wedge block 605 arc surface to apply pressure to the sliding column 608, the clamping pad 609 can reset under the action of the reset spring, so that the clamping pad 609 can continue to perform positioning and compensation work on the surface of the hollow cylinder.

[0032] Reference Figures 1 to 2 Above the support 7 is an adjustment table 8 for adjusting the position of the integrated machining table 3. The integrated machining table 3 can be equipped with machining tools such as lathe tools, milling cutters and grinding discs. A swingable cover plate 5 is provided on one side of the support 7.

[0033] During operation, when integrated machining of hollow cylinders is required, the integrated machining table 3 is driven by the adjusting table 8 to move away from the control table 1, and then the hollow cylinder is placed inside the outer shell 201. The outer surface of the hollow cylinder is first positioned and compensated, and then the inner surface is expanded and clamped. This can effectively improve the stability of the hollow cylinder during machining, and convert the offset that cannot be compensated by various tools into the purpose of compensation through clamping and positioning. This improves the stability and accuracy of the hollow cylinder when machining the weld position. In addition, during the machining process, the cover plate 5 can be swung to cover the machined part to prevent the splashing of iron filings. Furthermore, the rotation speed of the outer shell 201 is linked and matched with the tool feed speed of the integrated machining table 3 to ensure the accuracy of the machining trajectory.
