Description

Technical Field

[0001] The invention belongs to the technical field of deep hole boring machines for butt joints, and in particular relates to a novel numerically controlled deep hole boring machine for butt joints. Background Art

[0002] The CNC boring machine is a special boring machine equipped with two power systems and two flat rotating discs. It can perform pull boring and push boring at both ends of the workpiece at the same time for workpieces with large diameter holes and long lengths at both ends. It can ensure the high coaxial accuracy of the holes at both ends and the high-precision verticality of the front and back end faces of the holes. It is the preferred special machine tool for the front and back end faces and inner holes of large bearing seats, large generators and motor bases. The CNC deep hole boring machine is characterized by machining holes from both ends simultaneously through two opposite boring heads, thus ensuring the straightness and concentricity of the holes. This type of machine is usually used to process parts with a large aspect ratio, such as deep holes in gun barrels, cannon barrels, and machine tool spindles.

[0003] When an existing end-boring machine processes a cylindrical workpiece, the boring cutter needs to operate at both ends of the cylindrical workpiece at the same time. When the workpiece is simply placed on the processing table, the cylindrical workpiece is easy to roll, which will cause the workpiece axis to shift frequently during the processing. Once the axis shifts, not only will the bored deep hole deviate from the design requirements, causing a serious decrease in processing accuracy, but it may also cause uneven force on the boring cutter, aggravating tool wear. At the same time, the workpiece sometimes needs to be rotated to meet special processing technology requirements. At present, the workpiece position is usually adjusted manually by the staff, resulting in low processing efficiency. At the same time, manual adjustment of the position may cause the workpiece to shift. Summary of the invention

[0018] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-Figure 10 A novel CNC deep hole boring machine shown in the figure comprises a work bed 1, boring head frames 2 are slidably connected to both sides of the upper end of the work bed 1, one side of the two boring head frames 2 is connected to a flat rotary disk 3, the middle part of one side of the two flat rotary disks 3 is connected to a boring spindle 4, a slide rail 5 is connected to the middle part of the upper end of the work bed 1, a slide plate 6 is slidably connected to the upper end of the slide rail 5, the lower end of the slide plate 6 is located at the upper end of the slide rail 5 and slides, and the upper end of the slide plate 6 is connected to a supporting assembly; The boring head frame 2 can slide on both sides of the upper end of the workbed 1, and the position of the boring spindle 4 can be flexibly adjusted according to the processing position and length requirements of the workpiece. The flat turntable 3 is connected to the boring head frame 2, and it can provide multi-angle rotation and adjustment functions for the boring spindle 4, so that the boring spindle 4 can bore the workpiece at different angles. The slide rail 5 is installed in the middle of the upper end of the workbed 1, and the slide plate 6 cooperates with the slide rail 5 and can slide thereon, allowing the supporting assembly to move along the slide rail 5, so that the workpiece can be accurately positioned at the processing position of the boring spindle 4. The supporting assembly can be flexibly moved through the cooperation of the slide rail 5 and the slide plate 6, which facilitates the loading and unloading and positioning of the workpiece and improves the processing efficiency.

[0020] The supporting assembly includes a workbench 7, which is connected to the upper end of the slide plate 6, and a supporting box 8 is connected to the middle of the upper end of the workbench 7. Both sides of the lower end of the inner wall of the supporting box 8 are connected to hydraulic cylinders 9, and the upper ends of the two hydraulic cylinders 9 extend through and extend to the upper end of the supporting box 8 and are connected to a support plate 10, and both sides of the upper end of the support plate 10 are connected to mounting plates 11, and the upper ends of the two mounting plates 11 are rotatably connected to rollers 12, and both sides of the supporting box 8 are connected to supporting blocks 15, and the lower ends of the two supporting blocks 15 are connected to both sides of the upper end of the workbench 7, and the two sides of the upper end of the workbench 7 are symmetrically connected to clamping assemblies, and the middle of the upper end of the support plate 10 is connected to a supporting seat, and a driving roller 13 is rotatably connected between the two supporting seats, and one end of the driving roller 13 is connected to a first motor 14, and one side of the first motor 14 is connected to one of the supporting seats; The support box 8 provides support and protection for the hydraulic cylinder 9. The hydraulic cylinder 9 can drive the support plate 10 to move up and down, so as to adjust the height of the roller 12 to adapt to workpieces of different diameters. When the workpiece is placed on the roller 12, the roller 12 can rotate with the rotation of the workpiece, reducing the friction between the workpiece and the roller 12, and ensuring the smooth rotation of the workpiece. The support block 15 is connected to both sides of the support box 8, and one side of its upper end is inclined. The two support blocks 15 are symmetrically installed on both sides of the support box 8, and the upper working surfaces are inclined. The combination of the two forms a V-shaped groove structure, which can better fit the outer surface of the cylindrical workpiece and improve the stability of the workpiece placement. When the first motor 14 drives the driving roller 13 to rotate, the driving roller 13 generates friction with the surface of the workpiece, thereby driving the workpiece to rotate and realizing the circular processing of the workpiece. The V-shaped groove limits the lateral displacement of the workpiece to avoid the offset caused by vibration during processing. A wear-resistant coating or rubber cushion is added to the surface of the support block 15 to further protect the surface of the workpiece.

[0021] The clamping assembly includes a support plate 16, and the number of the support plates 16 is two groups. The support plates 16 are symmetrically connected to both sides of the upper end of the workbench 7. The lower part of one side of the support plate 16 is connected to a first cylinder 17, and one end of the first cylinder 17 extends through and extends to one side of the support plate 16. One end of the first cylinder 17 is rotatably connected to a moving plate 18. The shape of the upper end of the moving plate 18 is inclined. The lower part of one side of the moving plate 18 is rotatably connected to the middle part of one side of the support plate 16 through a rotating seat 19. The lower parts of both sides of the support plate 16 are connected to clamping assemblies, and the upper part of one side of the moving plate 18 is evenly connected to stabilizing blocks, and one side of one of the stabilizing blocks is connected A second motor 20 is connected, and the output end of the second motor 20 extends through one side of one of the stabilizing blocks. The output end of the second motor 20 is connected with an adjusting rod 21, and the adjusting rod 21 is rotatably connected between the two stabilizing blocks. One end of the adjusting rod 21 extends through one side of the movable plate 18, and one end of the adjusting rod 21 is connected with a pressing plate 22, and one side of the pressing plate 22 is rotatably connected with a pressing roller 23. One side of the support plate 16 is connected with guide plates 24 corresponding to both sides of the movable plate 18, and both sides of the movable plate 18 are connected with guide blocks corresponding to the two guide plates 24, and one end of the two guide blocks is respectively located on one side of the two guide plates 24 and slides; The support plate 16 is the basic supporting structure of the clamping assembly. When the first cylinder 17 is extended or retracted, it pushes the movable plate 18 to rotate around the rotating seat 19, thereby adjusting the angle and position of the movable plate 18. The stabilizing block on the movable plate 18 provides support for the second motor 20 and the adjusting rod 21. By controlling the rotation of the second motor 20, the adjusting rod 21 can be driven to rotate, thereby adjusting the angles of the pressing plate 22 and the pressing roller 23, so that the pressing roller 23 can better fit the surface of the workpiece. The guide plate 24 provides a guiding effect for the rotation of the movable plate 18 to ensure that the movement trajectory of the movable plate 18 is accurate.

[0022] The clamping assembly includes a connecting plate 25, and the connecting plate 25 is divided into two groups. The two connecting plates 25 are respectively connected to the lower parts of both sides of the support plate 16, and the two connecting plates 25 are connected to the second cylinders 26 on one side. The two second cylinders 26 are connected to the moving blocks 27 at one end. The lower ends of the two moving blocks 27 are respectively located on both sides of the upper end of the workbench 7 and slide. The upper ends of the two moving blocks 27 are connected to the fixed plates 28, and the upper ends of the fixed plates 28 are connected to the frames 29 on both sides. The middle part of the upper end of the frame 29 is connected to the third motor 30, and the output end of the third motor 30 is connected to the screw rod 31, and the lower end of the screw rod 31 extends through the inside of the frame 29. The outer wall of the screw rod 31 is slidably connected to the slider 32, and the slider 32 is located on the inner wall of the frame 29 and slides. One end of the slider 32 extends through and extends to one side of the frame 29, and one end of the slider 32 is connected to the shell 33, and the middle part of one side of the shell 33 is connected to the mounting block 34, and one end of the mounting block 34 extends through and extends to the inside of the shell 33, and the other end of the mounting block 34 is connected to A clamping block 35, one side of the clamping block 35 corresponding to the workpiece is made of silicone material, one side of the clamping block 35 is shaped in an inverted V-shaped structure, a connecting block 36 is connected to the middle of the upper end of the inner wall of the shell 33, and the middle of both sides of the connecting block 36 are rotatably connected to connecting rods 37, and the two connecting rods 37 are shaped in an inverted V-shaped structure, one end of the two connecting rods 37 is connected to a clamping block 38, and one end of the two clamping blocks 38 is respectively clamped to the two sides of the mounting block 34, and a clamping groove 39 is opened at the two sides of the mounting block 34 corresponding to the two clamping blocks 38, and the two clamping blocks 38 are respectively clamped to the inside of the clamping groove 39, and an electric telescopic rod 40 is connected to the middle of the upper end of the shell 33, and the lower end of the electric telescopic rod 40 sequentially penetrates the shell 33 and the connecting block 36 and extends to the lower end of the connecting block 36, and the lower end of the electric telescopic rod 40 is connected to a lower pressing block 41, and the middle of both sides of the lower pressing block 41 are rotatably connected to pull rods 42, and one end of the two pull rods 42 is rotatably connected to the middle of one side of the two connecting rods 37; By controlling the extension and retraction of the second cylinder 26, the moving block 27 can be driven to slide on both sides of the upper end of the workbench 7, so as to adjust the position of the fixing plate 28 and the frame 29. When the third motor 30 rotates, the screw rod 31 is driven to rotate, and the slider 32 slides on the screw rod 31, so as to realize the up and down movement of the slider 32, and then drive the shell 33 and the clamping block 35 to move up and down to adapt to workpieces of different heights. The clamping block 35 is connected to the shell 33 through the mounting block 34, and the mounting block 34 is inserted into the shell 33. The clamping is realized by the cooperation of the clamping block 38 and the clamping groove 39. A scale is connected to one side of the frame 29, and a positioning block is connected to one side of the shell 33, so that the staff can observe the position of the clamping block 35. The engaging surface of the block 38 is an arc surface, which matches the shape of the slot 39 to ensure self-locking when inserted. The hinge point of the pull rod 42 and the connecting rod 37 is located in the middle of the connecting rod 37, forming a lever structure to amplify the driving force of the electric telescopic rod 40. When the clamping block 35 needs to be replaced, the electric telescopic rod 40 is controlled to extend, and its lower end pushes the lower pressing block 41 to move downward; the pull rods 42 on both sides of the lower pressing block 41 move downward accordingly, pulling the middle parts of the two connecting rods 37 to rotate toward both sides of the shell 33. The shaft is rotatably connected to the upper end of the connecting block 36, and the lower end is fixedly connected to the clamping block 38. The rotation of the connecting rod 37 forces the two clamping blocks 38 to open outward, thereby disengaging from the clamping grooves 39 on both sides of the mounting block 34. At this time, the clamping block 35 can be axially withdrawn from the mounting block 34 to complete the disassembly; during installation, the mounting block 34 of the clamping block 35 is inserted into the shell 33, the electric telescopic rod 40 is contracted, and the pressing block 41 is pulled up, and the middle part of the connecting rod 37 is pushed inward by the pull rod 42, so that the clamping block 38 is clamped inward into the clamping groove 39 to achieve locking.

[0023] Working principle: When using the device, the cylindrical workpiece is placed on the two supporting blocks 15. Since the shape of one side of the upper end of the supporting block 15 is inclined, the two supporting blocks 15 are arranged in a V-shaped structure, which can improve the stability of the workpiece placement. At the same time, the multiple rollers 12 at the lower end of the support box 8 support the lower end of the workpiece to improve the stability of the workpiece. The two sides of the workpiece are fixed by the clamping components on both sides, and a boring tool is installed at one end of the boring shaft 4. The boring shaft 4 and the boring tool are moved to the two ends of the workpiece through the two boring head frames 2, and the two ends of the workpiece are processed by the boring shaft 4 and the boring tool on both sides; At the same time, a suitable clamping block 35 is selected according to the workpiece, and the electric telescopic rod 40 is used to push the lower pressing block 41 to move downward, and then the lower pressing block 41 drives the two pull rods 42 to move downward, and the two pull rods 42 push the two connecting rods 37 to move toward the two sides of the inner wall of the shell 33, so that the clamping block 35 can be disassembled; then a suitable clamping block 35 is selected, and the mounting block 34 on one side of the clamping block 35 is inserted into the shell 33, and the electric telescopic rod 40 pulls the lower pressing block 41 upward, which can drive the two pull rods 42 to move upward, and the two pull rods 42 pull the two connecting rods 37, so that the upper ends of the two connecting rods 37 are located at both sides of the two connecting blocks 36 and rotate, and the lower ends of the two connecting rods 37 and the two clamping blocks 38 move toward both sides of the mounting block 34, and the two clamping blocks 38 are respectively clamped into the two clamping grooves 39, so that the mounting block 34 can be clamped, which is convenient for quickly installing the clamping block 35; The height of the multiple clamping blocks 35 is adjusted according to the diameter of the workpiece, so that the clamping blocks 35 and the axis of the workpiece are on the same horizontal plane, and then the second cylinder 26 pushes the moving block 27, the fixing plate 28 and the frame 29 to move to one side of the workpiece, so that the two clamping blocks 35 are in a V-shaped shape and one side contacts the workpiece, ensuring the stability of the workpiece during processing. The multiple clamping blocks 35 on both sides of the workpiece can improve its stability. When the workpiece needs to be rotated, the clamping components on both sides of the workpiece are removed to release the fixation on both sides of the workpiece, and the two hydraulic cylinders 9 push the support plate 10 to move upward, so that the rollers 12 on both sides of the lower end of the workpiece rise to support the workpiece, so that the workpiece is slightly away from the two supporting blocks 15, and the two supporting blocks 15 do not support the workpiece, and then the first cylinder 17 pulls the moving plate 18 to one side of the support plate 16, so that the moving plate 18 is located on one side of the rotating seat 19 and rotates, and the position of the moving plate 18 is adjusted, thereby driving the pressure rollers 23 to move to the upper parts of both sides of the workpiece. The second motor 20 is used to adjust the angles of the adjusting rod 21, the pressing plate 22 and the two pressing rollers 23, so that the two pressing rollers 23 can fit the upper parts of the two sides of the workpiece, and the pressing rollers 23 on both sides of the workpiece can achieve the effect of pressing the workpiece tightly, avoiding the workpiece from deflecting, and improving the stability of the pressing rollers 23. The first motor 14 drives the driving roller 13 to rotate, and then the driving roller 13 and the workpiece generate friction, driving the workpiece to rotate, and while the workpiece rotates, the multiple rollers 12 and the multiple pressing rollers 23 rotate along with the workpiece, thereby improving the stability of the workpiece rotation; When the workpiece rotates to the processing position, the support plate 10 is pulled downward by the hydraulic cylinder 9, and the roller 12 drives the workpiece to move downward. The workpiece is placed above the two supporting blocks 15, and then the workpiece is clamped by the clamping assemblies on both sides, so that the boring spindles 4 on both sides can process the two ends of the workpiece.
