Description

Technical Field

[0001] The present application relates to the technical field of numerically controlled machine tools, and in particular to a milling and boring machine with ram deflection compensation. Background Art

[0002] Boring and milling machines are a kind of processing tools commonly used in the processing industry. They combine the functions of boring machines and milling machines in one. Their working principles are similar to those of boring machines and milling machines. The rotation of the tool is the main motion, and the movement of the workpiece is the feed motion. During the processing, the tool is usually moved, the workpiece remains stationary, the center of the tool is aligned with the center of the hole, and the tool is rotated for processing. This makes the processing more efficient and accurate, greatly improving product quality and labor efficiency. The ram is the core component of the machine tool. Relying on the ram, the machine tool can achieve long-distance and deep-hole processing. The accuracy of the ram will directly determine the lateral processing accuracy of the machine tool.

[0003] Since the lateral processing stroke is mainly achieved by the ram, due to the large stroke, the length of the ram extending from the spindle box is large, and the ram is heavy. The large extension length makes the ram very easy to deform, seriously affecting the processing accuracy of the machine tool. Summary of the invention

[0004] In order to reduce the deformation of the slide and thus improve the machining accuracy of the machine tool, the present application provides a milling and boring machine with slide deflection compensation.

[0005] The present application provides a milling and boring machine with ram deflection compensation, which adopts the following technical solution: A milling and boring machine with slide deflection compensation includes a slide and a slide seat. The slide seat is provided with a slide groove for the slide to slide. A track is installed in the slide groove. A rolling block slides in the track. The rolling block abuts against the slide. The rolling block is driven to move by a servo hydraulic cylinder in the slide seat.

[0006] By adopting the above technical solution, when the slide moves, the rolling block supports the slide and moves with the slide under the drive of the servo hydraulic cylinder. The sliding block supports the sliding block, reducing the possibility of deformation of the sliding block, thereby improving the machining accuracy of the machine tool.

[0007] Preferably, the track includes a first slide rail and a second slide rail, the second slide rail slides on the first slide rail, and the rolling block slides on the second slide rail; a fixing component for fixing the first slide rail is arranged in the first slide rail, and a supporting component for supporting the second slide rail is arranged on the side wall of the slide.

[0008] By adopting the above technical solution, when the distance moved by the slide is short, the rolling block slides on the second slide rail to support the slide; when the distance of the slide is large, when the rolling block moves to the port of the second slide rail and removes the slide groove, the rolling block releases the fixing component of the second slide rail, driving the second slide rail to slide on the first slide rail and extend out of the slide groove. At this time, the supporting component starts supporting the second slide rail, increasing the supporting effect of the second slide rail on the rolling block, thereby increasing the supporting strength of the rolling block on the slide and reducing the possibility of deformation of the slide.

[0009] Preferably, the fixed assembly comprises a fixed block and a first spring, a placement groove is provided in the first slide rail, the fixed block is slidably connected to the inner wall of the placement groove, two ends of the first spring are respectively fixedly connected to the fixed block and the inner wall of the placement groove, a fixing groove for the fixed block to be inserted is provided on the bottom wall of the second slide rail, a first inclined surface is provided on the fixed block, and the rolling block abuts against the first inclined surface.

[0010] By adopting the above technical solution, when the rolling block slides to the port of the second slide rail, the rolling block abuts against the first inclined surface on the fixed block and abuts against the fixed block through the first inclined surface to compress the first spring to move; when the fixed block moves away from the fixed groove, the rolling block drives the second slide rail to move together, and the bottom of the second slide rail is slidably connected to the fixed block, and the rolling block follows and always abuts against the slide, thereby increasing the distance supported by the slide.

[0011] Preferably, the support assembly includes a support rod, a first support block and a second support block. A support groove is provided on the side wall of the slide seat. The support rod is retractable. The first support block is fixedly connected to the side wall of the second slide rail close to the outside. The second support block is fixedly connected to the inner wall of the support groove. Both ends of the support rod are hinged to the first support block and the second support block respectively.

[0012] By adopting the above technical solution, when the second slide rail moves out of the slide groove following the movement of the slide ram, the support rod can enhance the supporting effect on the second slide rail.

[0013] Preferably, a compensation groove is opened on the inner wall of the slide groove, and a plurality of push rods are arranged in the compensation groove, the push rods are abutted on the side wall of the slide, a first sleeve is threadedly sleeved on the push rod, and a limiting component for limiting the rotation of the push rod is arranged in the compensation groove, a plurality of the first sleeves are evenly distributed in the compensation groove and rotate on the inner wall of the compensation groove, and a driving mechanism for driving the first sleeve to rotate is arranged in the compensation groove.

[0014] By adopting the above technical solution, when the slide moves, the first sleeve rotates under the drive of the driving mechanism, and the push rod follows the rotation of the first sleeve under the action of the limiting component and moves linearly to the outside of the first sleeve, so that the push rod can abut on the slide and give the slide a downward force, thereby balancing the downward force of the slide's moving end, so that the slide remains horizontal and the accuracy of machine tool processing is improved. When the slide moves different distances according to the work, multiple push rods move in sequence according to the moving distance of the slide, so that the push rod closest to the end of the slide abuts against the slide.

[0015] Preferably, the driving mechanism includes a first worm, a connecting rod and a plurality of first turbines, the plurality of first turbines and the plurality of first sleeves are arranged in one-to-one correspondence, the first turbine is fixedly sleeved on the first sleeve; the connecting rod rotates on the inner wall of the compensation groove, the first worm is penetrated by the connecting rod, a limiting block is fixedly connected to the side wall of the first worm, a limiting groove is provided in the connecting rod for the sliding of the limiting block, and the driving mechanism also includes a rotating component for driving the connecting rod to rotate and a moving component for driving the first worm to move.

[0016] By adopting the above technical scheme, the connecting rod rotates under the action of the rotating component. When the connecting rod rotates, the first worm gear is driven to rotate together due to the action of the limit block. At the same time, the first worm gear moves along the moving direction of the slide under the action of the moving component. Therefore, during the movement of the slide, the first worm gear rotates and moves outward, so that the first worm gear can engage with the first turbines on multiple first sleeves in sequence. Therefore, during the movement of the slide, the push rod farthest from the compensation groove to the slide can move at the beginning. As the moving distance of the slide increases, the push rods close to the rolling block move in turn, so that they can follow the moving distance of the slide, so that the push rods at different positions abut against the side wall of the end of the slide, thereby balancing the force of the slide moving end falling downward.

[0017] Preferably, the rotating assembly includes a rack, a first gear, a first bevel gear, a second bevel gear, a second worm and a second turbine. A storage groove is opened on the side wall of the sliding pillow. The rack is fixedly mounted on the inner wall of the storage groove. A first rotating rod is rotatably arranged on the inner wall of the compensation groove.

A bracket is fixedly connected to the inner wall of the compensation groove, and the second worm rotates on the bracket. The first bevel gear is fixedly sleeved on the end of the first rotating rod, and the second bevel gear is fixedly sleeved on the second worm. The second bevel gear and the first bevel gear are meshed with each other. The second turbine is fixedly sleeved on the connecting rod, and the second turbine and the second worm are meshed with each other.

[0018] By adopting the above technical solution, when the slide moves, the rack drives the first gear to rotate, the first gear drives the first bevel gear to rotate through the first rotating rod, the rotation of the first bevel gear drives the second bevel gear to rotate, the rotation of the second bevel gear drives the second worm to rotate, the rotation of the second worm drives the second turbine to rotate, the rotation of the second turbine drives the connecting rod to rotate, and under the action of the limit block, the rotation of the connecting rod drives the first worm to rotate, and then the first sleeve can be driven to rotate.

[0019] Preferably, the moving assembly includes a screw rod, a connecting block, a third bevel gear and a fourth bevel gear, the screw rod is inserted through and rotates on the outer side wall of the slide seat, the connecting block is fixedly connected to the end of the first worm gear away from the first turbine, the screw rod is threadedly connected to the connecting block, the third bevel gear is fixedly sleeved on the end of the second worm gear away from the second bevel gear, the fourth bevel gear is fixedly sleeved on one end of the screw rod, the third bevel gear and the fourth bevel gear are meshed, and a guide rod is fixedly connected to the side wall of the slide seat, and the connecting block slides on the guide rod.

[0020] By adopting the above technical solution, when the second worm rotates, it drives the third bevel gear to rotate, the third bevel gear rotates to drive the fourth bevel gear to rotate, the fourth bevel gear rotates to drive the screw to rotate, the connecting block moves along the screw under the guidance of the guide rod, and the connecting block drives the first worm to move, so that the first worm follows the moving distance of the slide and engages with the first turbine on the abutment rod at different positions.

[0021] Preferably, the limiting assembly includes a limiting block and a fixed block, the fixed block is fixedly connected to the inner wall of the compensation groove, the push rod passes through and slides on the fixed block, the limiting block is fixedly connected to the inner wall of the fixed block, and the push rod is provided with a limiting groove for the limiting block to slide.

[0022] By adopting the above technical solution, when the first sleeve rotates, the stopper rod is restricted from rotating under the restriction of the restriction block, thereby moving in a straight line.

[0023] Preferably, a second spring is sleeved on the support rod, the second spring is in a compressed state, and two ends of the second spring are respectively in contact with the first support block and the second support block.

[0024] By adopting the above technical solution, the second spring is always in a compressed state, and its two ends abut against the first support block and the second support block and have a tendency to move away from each other, thereby increasing the supporting force on the first support block.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the ram moves, the rolling block supports the ram and moves with the ram under the drive of the servo hydraulic cylinder. The rolling block supports the ram, reducing the possibility of deformation of the ram, thereby improving the machining accuracy of the machine tool; 2. When the distance moved by the ram is short, the rolling block slides on the second slide rail to support the ram. When the distance moved by the ram is long, when the rolling block moves to the end of the second slide rail and removes the slide groove, the rolling block releases the fixing component of the second slide rail, driving the second slide rail to slide on the first slide rail and extend out of the slide groove. At this time, the supporting component starts supporting the second slide rail, increasing the supporting effect of the second slide rail on the rolling block, thereby increasing the supporting strength of the rolling block on the ram and reducing the possibility of deformation of the ram. 3. Under the joint action of the moving assembly and the rotating assembly, the first worm gear rotates and moves outward during the movement of the slide, so that the first worm gear can mesh with the first turbines on the multiple first sleeves in sequence. Therefore, during the movement of the slide, the abutment rod farthest from the slide from the compensation groove can move at the beginning, and as the moving distance of the slide increases, the abutment rods close to the rolling block can move in sequence, so that they can follow the moving distance of the slide, so that the abutment rods at different positions abut against the side wall of the end of the slide, thereby balancing the force of the slide moving end falling downward.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] The embodiment of the present application discloses a milling and boring machine with ram deflection compensation.

[0037] Embodiment 1 like Figure 1 As shown, it includes a slide 1 and a slide seat 2. A slide groove 3 for the slide 1 to slide is opened on the slide seat 2 in the horizontal direction. A mounting groove is opened on the inner wall at the bottom of the slide groove 3 along its extension direction. A track 4 is installed in the mounting groove. A rolling block 5 slides on the track 4. The rolling block 5 is in the shape of a rectangular parallelepiped. A servo hydraulic cylinder 54 is connected to the rolling block 5. The servo hydraulic cylinder 54 drives the rolling block 5 to move.

[0038] The implementation principle of the first embodiment is as follows: when the slide 1 moves outward, the rolling block 5 moves along with the slide 1 under the drive of the servo hydraulic cylinder 54. The rolling block 5 can support the slide 1 and compensate for the downward force of its moving end, thereby reducing the possibility of deformation of the slide 1 and improving the machining accuracy of the machine tool.

[0039] Embodiment 2 The difference between the second embodiment and the first embodiment is that: Figure 2 and Figure 3As shown, the track 4 includes a first slide rail 6 and a second slide rail 7. The first slide rail 6 is fixedly welded to the inner wall of the mounting groove, and the second slide rail 7 slides on the first slide rail 6. A slide rod 52 is fixedly welded inside the second slide rail 7, and the rolling block 5 slides on the slide rod 52. A fixing component 9 for fixing the second slide rail 7 is arranged inside the first slide rail 6, and a supporting component 8 for supporting the second slide rail 7 is arranged on the side wall of the slide seat 2.

[0040] like Figure 2 and Figure 4 As shown, the fixing assembly 9 includes a fixing block 10 and a first spring 11. A placement groove 12 is provided on the inner wall at the bottom of the first slide rail 6 in the vertical direction. The fixing block 10 is in the shape of a rectangular parallelepiped and is slidably connected to the inner wall of the placement groove 12 in the vertical direction. A first inclined surface 14 is provided on the top of the fixing block 10. The first spring 11 is arranged in the placement groove 12 in the vertical direction, and its two ends are respectively fixedly welded to the fixing block 10 and the inner wall of the placement groove 12. A fixing groove 13 for plugging the fixing block 10 is provided on the lower end surface of the second slide rail 7 in the vertical direction. The fixing groove 13 is connected to the inner slideway of the second slide rail 7. The rolling block 5 abuts against the first inclined surface 14. A stop block 53 is provided on the lower end surface of the rolling block 5 so as to slide in the vertical direction. A second inclined surface 54 is provided on the stop block 53, and the stop block 53 abuts against the fixed block 10. The support assembly 8 includes a support rod 15, a first support block 16 and a second support block 17. The support rod 15 is retractable. A support groove 49 is opened on the side wall of the slide seat 2 in the vertical direction. The support groove 49 and the mounting groove are vertically connected to each other. The first support block 16 is fixedly welded to the side wall of the second slide rail 7 close to the outside. The second support block 17 is fixedly welded to the inner wall at the bottom of the support groove 49. The two ends of the support rod 15 are respectively hinged to the first support block 16 and the second support block 17. A second spring 48 is sleeved on the support rod 15. The second spring 48 is always in a compressed state. The two ends of the second spring 48 are respectively abutted against the first support block 16 and the second support block 17.

[0041] The implementation principle of the second embodiment is as follows: when the distance of the ram 1 is short, the rolling block 5 slides on the second slide rail 7 to support the ram 1, and the second slide rail 7 remains stationary under the plug-in fixation of the fixed block 10. At this time, the support rod 15 is placed in the support groove 49 along the vertical direction. When the distance of the ram 1 gradually increases, the rolling block 5 follows the movement of the ram 1 and moves to the end of the second slide rail 7. The rolling block 5 abuts against the first inclined surface 14 on the fixed block 10 and abuts against the fixed block 10 through the first inclined surface 14 to compress the first spring 11 to move. Subsequently, when the rolling block 5 abuts against the inner wall of the end of the second slide rail 7, the abutment 53 on the rolling block 5 is aligned with the fixed groove 13, and the fixed block 10 is completely separated from the fixed groove 13 under the drag of the abutment 53. At this time, the rolling block 5 abuts against the side wall of the end of the second slide rail 7 located on the outside and drives the second slide rail 7 to move, thereby increasing the moving range of the rolling block 5. The rolling block 5 moves with the movement of the ram 1 and can be supported at the best balance position of the ram 1. When the second slide rail 7 is released and moves outward, the first support block 16 moves with the second slide rail 7, thereby driving the support rod 15 to move obliquely and be stretched. The support rod 15 can enhance the supporting effect on the second slide rail 7. The second spring 48 on the support rod 15 is always in a compressed state, and its two ends abut against the first support block 16 and the second support block 17 and have a tendency to move away from each other, thereby increasing the supporting force on the first support block 16, reducing the possibility of deformation of the slide 1, and thereby improving the machining accuracy of the machine tool.

[0042] Embodiment 3 The difference between the third embodiment and the second embodiment is that: Figure 6 and Figure 7As shown, a compensation groove 18 is provided on the inner wall of the top of the slide groove 3, and a plurality of push rods 19 are arranged in the vertical direction in the compensation groove 18. The plurality of push rods 19 are arranged sequentially from right to left. The bottom of the push rod 19 can be in contact with the upper end surface of the ram 1. A first sleeve 20 is threadedly sleeved on the push rod 19. The top of the first sleeve 20 is rotatably connected to the inner wall of the top of the compensation groove 18. A limiting component 21 for limiting the rotation of the push rod 19 is provided in the compensation groove 18. The limiting component 21 includes a limiting block 45 and a fixed block 10. The fixed block 10 is fixedly welded to the inner wall of the compensation groove 18. The push rod 19 is penetrated and slides on the fixed block 10. The limiting block 45 is fixedly welded on the inner wall of the fixed block 10. The push rod 19 is provided with a limiting groove 47 along its length direction for the sliding of the limiting block 45. A driving mechanism 22 for driving the plurality of first sleeves 20 to rotate sequentially is provided in the compensation groove 18. When the slide 1 moves, the driving mechanism 22 starts. Under the action of the driving mechanism 22, the first sleeve 20 farthest from the outside of the slide 1 starts to rotate first. As the slide 1 moves, the first sleeve 20 is driven from the inside to the outside in sequence. When the first sleeve 20 rotates, the push rod 19 is limited by the limiting block 45 to limit the rotation, so that it moves downward in a straight line, and then the bottom of the push rod 19 abuts against the side wall of the slide 1. As the slide 1 moves, the push rod 19 always abuts against the side wall of the slide 1 at one end of the slide 1 in the slide groove 3, thereby giving a downward force to the end of the slide 1, thereby balancing the downward falling force of the moving end of the slide 1, so that the slide 1 remains horizontal and the machining accuracy of the machine tool is improved.

[0043] like Figure 6 and Figure 8 As shown, the driving mechanism 22 includes a first worm 23, a connecting rod 26 and a plurality of first turbines 24. The plurality of first turbines 24 and the plurality of first sleeves 20 are arranged one by one, and the first turbines 24 are fixedly sleeved on the outer wall of the first sleeve 20. The connecting rod 26 is rotatably arranged on the inner wall of the compensation groove 18, the first worm 23 is penetrated by the connecting rod 26, a limiting block 50 is fixedly welded on the side wall of the first worm 23, and a limiting groove 51 for the limiting block 50 to slide is provided in the connecting rod 26. The driving mechanism 22 also includes a rotating assembly 27 for driving the connecting rod 26 to rotate and a moving assembly 28 for driving the first worm 23 to move.

[0044] like Figure 4 and Figure 8As shown, the rotating assembly 27 includes a rack 29, a first gear 30, a first bevel gear 31, a second bevel gear 32, a second worm 35 and a second turbine 36. A storage groove 37 is opened on the top side wall of the ram 1 along its length direction. The rack 29 is fixedly welded on the inner wall of the storage groove 37. A first rotating rod 39 is rotatably arranged on the inner wall of the compensation groove 18. The first gear 30 is rotatably mounted on the first rotating rod 39 and meshes with the rack 29. The first bevel gear 31 is fixedly mounted on the end of the first rotating rod 39. A bracket 25 is fixedly welded in the compensation groove 18. The second worm 35 rotates on the bracket 25. The second worm 35 rotates in the vertical direction. The second bevel gear 32 is fixedly mounted on the bottom end of the second worm 35. The second turbine 36 is fixedly mounted on the connecting rod 26. The second worm 35 and the second turbine 36 are meshed.

[0045] like Figure 6 and Figure 8 As shown, the moving assembly 28 includes a screw 40, a connecting block 41, a third bevel gear 33 and a fourth bevel gear 43. The screw 40 is horizontally penetrated and rotatably arranged on the side wall of the slide 2. The connecting block 41 is fixedly welded to the end of the first worm 23 away from the first turbine 24 and the connecting block 41 abuts against the end face of the connecting rod 26. The connecting block 41 is threadedly connected to the screw 40. The third bevel gear 33 is fixedly sleeved on the end of the second worm 35 away from the second bevel gear 32. The fourth bevel gear 43 is fixedly sleeved on the end of the screw 40. The third bevel gear 33 and the fourth bevel gear 43 are meshed. A guide rod 44 is fixedly welded on the side wall of the slide 2 in the horizontal direction, and the connecting block 41 slides on the guide rod 44.

[0046] The implementation principle of the third embodiment of the present application is: when the slide 1 moves, the rack 29 moves with the slide 1, the rack 29 moves to drive the first gear 30 to rotate, the rotation of the first gear 30 drives the first rotating rod 39 to rotate, the rotation of the first rotating rod 39 drives the first bevel gear 31 to rotate, the rotation of the bevel gear drives the second worm 35 to rotate, the rotation of the second worm 35 drives the second turbine 36 to rotate, the second turbine 36 rotates to drive the connecting rod 26 to rotate, and the rotation of the connecting rod 26 drives the first worm 23 to rotate. At the same time, the second worm 35 rotates and drives the lead screw 40 to rotate through the meshing of the third bevel gear 33 and the fourth bevel gear 43. The connecting block 41 moves along the lead screw 40 under the action of the guide rod 44. The movement of the connecting block 41 drives the first worm 23 to move outward in the horizontal direction, so that the first worm 23 rotates and moves, so that the first worm 23 follows the movement distance of the slide 1 and meshes with the first turbine 24 on the push rod 19 at different positions, and drives the push rod 19 to move downward in turn. Then, after the slide 1 finishes moving, there is always a push rod 19 in a relative position to abut against the slide 1, further balancing the force of the slide 1 moving outward, thereby improving the machining accuracy of the machine tool.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
