Technical Field
[0001] The invention relates to the technical field of vertical drilling machines, in particular to a vertical drilling machine with a dynamic buffer mechanism. Background Art
[0002] As an important metal cutting machine tool, vertical drilling machine plays a key role in machinery manufacturing and repair factories. It is widely used in machinery manufacturing and repair factories. It is mainly used to process holes in medium and small workpieces. Vertical drilling machine is a drilling machine with vertically arranged spindle and fixed center position, referred to as vertical drilling. Before vertical drilling machine processing, the position of the workpiece on the workbench must be adjusted so that the center line of the processed hole is aligned with the tool axis. During processing, the workpiece is fixed, the spindle rotates in the sleeve and feeds axially with the sleeve, the workbench and the spindle box can be adjusted along the column guide rail to adapt to workpieces of different heights. As a type of drilling machine, vertical drilling machine is also a relatively common metal cutting machine tool. It has the characteristics of wide application and high precision, and is suitable for batch processing.
[0003] Chinese patent application CN113477963A discloses a vertical drilling machine for workpiece processing, including a bed, a base, a slotting workbench and a crank handle. By clamping the workpiece on the inner wall of the slotting workbench, the clamping of the slotting workbench and the adjustment of other devices can accurately control the position of the drilling hole, and will not cause the precision of the processed workpiece to be low due to factors such as jitter and error, effectively reducing the situation where raw materials are scrapped due to large errors, improving the quality and precision of the product, and simplifying the processing process.
[0004] When the above-mentioned prior art is in use, the drilling position is precisely controlled by clamping the slotting workbench and adjusting the other devices. However, in actual use, during the drilling process, the interaction between the drill bit and the workpiece will generate vibration, causing the position of the drill bit during the processing to shift due to the vibration, making the position of the processed hole inaccurate, and during the drilling process, the drill bit may encounter hard points or suddenly break, generating a large impact force, which will directly act on key components such as the machine tool spindle, guide rails, and the workpiece, causing damage to the machine tool or scrapping of the workpiece, affecting its use.

[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. During the processing, the interaction between the drill bit and the workpiece will generate vibration. When the drill bit is impacted in the vertical direction, the first spring and the second spring provide preload on the polished rod, and the first spring and the second spring absorb and buffer the impact energy. The preload adjustment component can be used to change the preload of the first spring and the second spring, which can effectively absorb and buffer the impact and vibration energy generated in the processing process. When the drill bit is impacted in the horizontal direction, the first slider moves in the rectangular through groove, and the horizontal buffer mechanism plays a role at the same time, absorbing and buffering the impact energy, protecting the drill bit and the workpiece from damage, thereby omni-directionally absorbing the impact and vibration energy generated in the processing process, and improving the processing accuracy and stability.
[0018] 2. By rotating the knob, the third threaded rod is driven to rotate by the knob. Since the third threaded rod is threadedly connected to the fixed plate, the rotational motion is converted into the linear motion of the moving seat. The moving seat drives the rotating seat and the connecting rod to move together, thereby pushing the clamping plate close to the workpiece to fix the workpiece. With the assistance of the anti-deviation mechanism, the cutting force is prevented from acting on the workpiece during the drilling and cutting process, causing a slight deviation of the workpiece, thereby affecting the accuracy of the drilling.
[0019] 3. By rotating the handle, the third rotating rod is driven to rotate, and the rotation of the third rotating rod further drives the gear to rotate. Due to the meshing relationship between the gear and the rack, the moving ring is driven to move on the connecting column, and the connecting column drives the workbench to move, so that the height of the workbench can be adjusted as needed.

DETAILED DESCRIPTION
[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0035] See also Figures 1 to 13As shown, the present invention provides a vertical drilling machine with a dynamic buffer mechanism, including a base 1, a connecting column 2 is installed on the base 1, a control box 3 is installed at one end of the connecting column 2, a drill bit 4 that can move along the vertical direction is arranged on the control box 3, a workbench 5 is arranged on the connecting column 2, an adjustment component 6 for adjusting the height of the workbench 5 is arranged between the connecting column 2 and the workbench 5, a moving plate 71 is installed on the drill bit 4 through a bearing, a rectangular through groove is opened on the moving plate 71, a first slider 72 is arranged in the rectangular through groove, the first slider 72 can move along the rectangular through groove, and a adjusting component 6 for adjusting the height of the workbench 5 is arranged in the rectangular through groove. A horizontal buffer mechanism for absorbing the impact of the drill bit 4 in the horizontal direction, a through hole is opened on the first slider 72, a light rod 73 is arranged in the through hole, mounting seats 74 are arranged at both ends of the light rod 73, the mounting seats 74 are connected to the control box 3, a first spring 75 is sleeved on the top end of the first slider 72 on the light rod 73, a second spring 76 is sleeved on the bottom end of the first slider 72 on the light rod 73, a preload adjustment component for compressing or stretching the first spring 75 and the second spring 76 to change the preload is arranged at one end of the movable plate 71, and a clamping assembly 8 for fixing the workpiece to be processed is arranged on the workbench 5.
[0036] By placing the workpiece to be processed on the workbench 5 and fixing it by the clamping assembly 8, and adjusting the height of the workbench 5 by the adjusting assembly 6 according to the height of the workpiece and the processing requirements, after starting the drilling machine, the drill bit 4 moves in the vertical direction under the drive of the control box 3 to drill the workpiece. During the processing, the interaction between the drill bit 4 and the workpiece will generate vibration. When the drill bit 4 is impacted in the vertical direction, the first spring 75 and the second spring 76 provide a preload on the light rod 73. The first spring 75 and the second spring 76 absorb and buffer the impact energy, and the preload adjustment component can be used to change the preload of the first spring 75 and the second spring 76, which can effectively absorb and buffer the impact and vibration energy generated in the processing process. When the drill bit 4 is impacted in the horizontal direction, the first slider 72 moves in the rectangular through groove, and the horizontal buffer mechanism plays a role at the same time to absorb and buffer the impact energy, protect the drill bit 4 and the workpiece from damage, thereby omni-directionally absorbing the impact and vibration energy generated in the processing process, thereby improving the processing accuracy and stability.
[0037] See also Figures 1 to 6 As shown, the preload force adjustment component includes a first rectangular block 77 and a second rectangular block 78; the first rectangular block 77 is movably arranged on the light rod 73 and is located above the first slider 72, and one end of the first spring 75 abuts against the first rectangular block 77; the second rectangular block 78 is movably arranged on the light rod 73 and is located below the first slider 72, and one end of the second spring 76 abuts against the second rectangular block 78, and one end of the movable plate 71 is provided with a synchronization mechanism for driving the first rectangular block 77 and the second rectangular block 78 to move toward or relative to each other.
[0038] Before the drilling machine starts working, the first rectangular block 77 and the second rectangular block 78 are respectively located at preset positions on the light rod 73, and the first spring 75 and the second spring 76 are in a certain pre-tightened state, providing basic buffering force for the drill bit 4. When the pre-tightening force needs to be increased, the synchronization mechanism is activated to drive the first rectangular block 77 and the second rectangular block 78 to move toward each other, which will cause the first spring 75 and the second spring 76 to be further compressed, thereby increasing their pre-tightening force. When the drill bit 4 is impacted, the first slider 72 will move along the light rod 73, compressing or stretching the first spring 75 and the second spring 76. Since the pre-tightening force of the first spring 75 and the second spring 76 has been adjusted by the synchronization mechanism, the first spring 75 and the second spring 76 can respond to the impact more accurately, absorb and buffer the impact and vibration energy generated during the processing in the vertical direction, and protect the drill bit 4 and the workpiece from damage.
[0039] See also Figures 4 to 6 As shown, the synchronization mechanism includes a first rotating rod 79, a first rotating plate 710, a slide rail 711, a lower moving block 712, a first hinge rod 713, a second hinge rod 714, an upper moving block 715, a first connecting plate 716 and a second connecting plate 717; the first rotating rod 79 is arranged at one end of the moving plate 71; the first rotating plate 710 is arranged on the first rotating rod 79; the slide rail 711 is arranged on both sides of the moving plate 71; the lower moving block 712 is movably arranged on the slide rail 711; a threaded driving screw for driving the lower moving block 712 to move is installed on the slide rail 711 Components; the first hinged rod 713 is arranged on the lower moving block 712, and one end of the first hinged rod 713 is hinged to the first rotating plate 710; the second hinged rod 714 is arranged on the first rotating plate 710; the upper moving block 715 is arranged on the slide rail 711, and one end of the second hinged rod 714 is hinged to the upper moving block 715; the first connecting plate 716 is installed on one side of the lower moving block 712, and the first connecting plate 716 is connected to the second rectangular block 78; the second connecting plate 717 is arranged on one side of the upper moving block 715, and the second connecting plate 717 is connected to the first rectangular block 77.
[0040] The lower moving block 712 is driven to move on the slide rail 711 by the threaded driving component. When the lower moving block 712 moves upward, the first rotating plate 710 is driven to rotate by the first hinge rod 713, and the rotation of the first rotating plate 710 is transmitted to the upper moving block 715 through the setting of the second hinge rod 714, so that the upper moving block 715 also moves on the slide rail 711, and the movement is transmitted to the second rectangular block 78 and the first rectangular block 77 through the first connecting plate 716 and the second connecting plate 717, thereby realizing the toward or relative movement of the first rectangular block 77 and the second rectangular block 78.
[0041] See also Figure 6As shown, the threaded drive component includes a connecting frame 718, a first threaded rod 719, a first motor 720 and a first drive block 721; the connecting frame 718 is installed on one side of the slide rail 711; the first threaded rod 719 is arranged in the connecting frame 718; the first motor 720 is arranged at the top of the connecting frame 718, and the output end of the first motor 720 is connected to the first threaded rod 719; the first drive block 721 is arranged on the first threaded rod 719.
[0042] By starting the first motor 720, the first motor 720 drives the first threaded rod 719 in the connecting frame 718 to rotate, and the rotation of the first threaded rod 719 drives the first driving block 721 to move. Since the first driving block 721 is connected to the lower moving block 712, the lower moving block 712 is driven to move on the slide rail 711.
[0043] The preload force adjustment component also includes a vibration sensor installed on the first slider 72 and a controller installed in the control box 3. The vibration sensor is used to monitor the vibration and impact during the processing. Specifically, the tension sensor and controller do not fall within the scope of protection of the present application and are therefore not shown in the figure. The vibration and impact are monitored by the vibration sensor. When the vibration amplitude is greater than a preset value, the vibration sensor transmits a signal to the controller, which then starts the first motor 720.
[0044] See also Figures 7 to 9 As shown, the horizontal buffer mechanism includes a first fixed groove 722, a slide bar 723, a second slider 724, a third spring 725 and a third rectangular block 726; the first fixed groove 722 is opened on the inner wall of the rectangular through groove; the slide bar 723 is arranged in the first fixed groove 722; the second slider 724 is arranged on both sides of the first slider 72, and the second slider 724 is slidably arranged on the slide bar 723; the third spring 725 is sleeved on the slide bar 723, and one end of the third spring 725 abuts against the second slider 724; the third rectangular block 726 is movably arranged on the slide bar 723, and a moving component for driving the third rectangular block 726 to move is arranged in the rectangular through groove, and a linkage component for ensuring coordinated movement between the moving component and the synchronization mechanism is installed between the moving component and the synchronization mechanism.
[0045] When there is no external force, the second slider 724 and the third rectangular block 726 are respectively located at the initial positions on the slide bar 723, and the third spring 725 is in a natural state. When the first slider 72 is subjected to a horizontal impact force, the impact force will be transmitted to the second slider 724. Under the action of the impact force, the second slider 724 slides along the slide bar 723 and compresses the third spring 725. The third spring 725 undergoes elastic deformation when compressed and stores the energy generated by the impact force. When the synchronization mechanism moves, the linkage assembly transmits this movement information to the moving part, thereby driving the third rectangular block 726 to move accordingly. The third rectangular block 726 moves on the slide bar 723 and compresses the third spring 725, thereby adjusting the preload force of the third spring 725, being able to respond to the impact more accurately, and absorbing and buffering the impact and vibration energy generated during the processing in the horizontal direction.
[0046] See also Figures 7 to 9 As shown, the movable component includes a second fixed groove 727, a second threaded rod 728, a second driving block 729 and an abutment plate 730; the second fixed groove 727 is opened on the inner wall of the rectangular through groove and is located on one side of the first fixed groove 722; the second threaded rod 728 is arranged in the second fixed groove 727, and one end of the second threaded rod 728 passes through the movable plate 71 and extends outward; the second driving block 729 is arranged on the second threaded rod 728; and the abutment plate 730 is arranged on the second driving block 729.
[0047] When the synchronization mechanism moves, the linkage assembly will transmit the movement information to the moving part to drive the second threaded rod 728 to rotate. The rotation of the second threaded rod 728 drives the second drive block 729 to move, and the movement of the second drive block 729 drives the abutment plate 730 to move. Since one end of the abutment plate 730 abuts against the third rectangular block 726, the movement of the second drive block 729 drives the third rectangular block 726 to move on the slide rod 723, thereby adjusting the preload force of the third spring 725.
[0048] See also Figure 7 and Figure 8 As shown, the linkage assembly includes a first synchronous wheel 731, a second synchronous wheel 732 and a synchronous belt 733; the first synchronous wheel 731 is installed on the extended end of the second threaded rod 728; the second synchronous wheel 732 is arranged on the first rotating rod 79; and the synchronous belt 733 is sleeved on the first synchronous wheel 731 and the second synchronous wheel 732.
[0049] When the first rotating plate 710 rotates, it will synchronously drive the first rotating rod 79 to rotate. When the first rotating rod 79 rotates, it will drive the second synchronous wheel 732 to rotate. Since a synchronous belt 733 is provided on the first synchronous wheel 731 and the second synchronous wheel 732, the rotation of the second synchronous wheel 732 drives the first synchronous wheel 731 to rotate, and the first synchronous wheel 731 drives the second threaded rod 728 to rotate, thereby achieving the effect of driving the second threaded rod 728 to rotate.
[0050] See also Figures 10 to 12 As shown, the clamping assembly 8 includes a fixed plate 81, a third threaded rod 82, a movable seat 83, a knob 84, a rotating seat 85, a connecting rod 86 and a clamping plate 87; two fixed plates 81 are provided and are arranged at the top of the workbench 5; the third threaded rod 82 is arranged on the fixed plate 81; the movable seat 83 is arranged at one end of the third threaded rod 82; the knob 84 is arranged at the other end of the third threaded rod 82; the rotating seat 85 is installed on one side of the movable seat 83; the connecting rod 86 is arranged on the rotating seat 85; the clamping plate 87 is installed on the connecting rod 86, and an anti-deviation mechanism is also provided between the clamping plate 87 and the movable seat 83 to prevent the workpiece from deviating due to cutting.
[0051] By rotating the knob 84, the third threaded rod 82 is driven to rotate by the knob 84. Since the third threaded rod 82 is threadedly connected to the fixed plate 81, the rotational motion is converted into linear motion of the moving seat 83. The moving seat 83 drives the rotating seat 85 and the connecting rod 86 to move together, thereby pushing the clamping plate 87 close to the workpiece to fix the workpiece. With the assistance of the anti-deviation mechanism, the cutting force is prevented from acting on the workpiece during the drilling process, causing a slight deviation of the workpiece, thereby affecting the accuracy of the drilling.
[0052] See also Figures 10 to 12 As shown, the anti-deviating mechanism includes a fine-tuning box 88, a connecting seat 89, a fine-tuning rod 810, a limit plate 811, a fourth spring 812, a second rotating rod 813, a second rotating plate 814 and a second motor 815; the fine-tuning box 88 is arranged on the side of the moving seat 83 away from the clamping plate 87; the connecting seat 89 is provided with two and symmetrically arranged on one side of the clamping plate 87; the fine-tuning rod 810 is rotatably arranged on the connecting seat 89, and one end of the fine-tuning rod 810 passes through the moving seat 83 and extends into the fine-tuning box 88 ; The limiting plate 811 is arranged on the fine-tuning rod 810; the fourth spring 812 is sleeved on the fine-tuning rod 810, one end of the fourth spring 812 abuts against the limiting plate 811, and the other end of the fourth spring 812 abuts against the inner wall of the fine-tuning rod 810; the second rotating rod 813 is arranged in the fine-tuning box 88; the second rotating plate 814 is arranged on the second rotating rod 813; the second motor 815 is arranged on the top of the fine-tuning box 88, and the output end of the second motor 815 is connected to the second rotating rod 813.
[0053] When the cutting force acts on the workpiece during the drilling process, the workpiece will drive the clamping plate 87 to deviate. When the clamping plate 87 deviates, it will drive the fine-tuning rod 810 to move into the fine-tuning box 88, stretch the fourth spring 812, and contact the second rotating plate 814 through the movement of the fine-tuning rod 810, driving the second rotating plate 814 to rotate along the second rotating rod 813. At this time, by starting the second motor 815, the second motor 815 drives the second rotating rod 813 to rotate, and the rotation of the second rotating rod 813 drives the second rotating plate 814 to rotate. The movement adjustment of the fine-tuning rod 810 is transmitted to the clamping plate 87 through the connecting seat 89, so that the clamping plate 87 can fine-tune the workpiece to correct its offset state, thereby ensuring the accuracy of processing.
[0054] See also Fig.10 and Fig.12 As shown, a first conductive sheet 816 is provided on the side of the clamping plate 87 close to the movable seat 83, a second conductive sheet 817 is provided on the side of the movable seat 83 close to the clamping plate 87, and a warning light 818 is also provided on the top of the fine-tuning box 88. The first conductive sheet 816 and the second conductive sheet 817 are electrically connected to the warning light 818 respectively.

The first conductive sheet 816 and the second conductive sheet 817 are not in contact under normal circumstances, but when the clamping plate 87 is offset, the first conductive sheet 816 will contact the second conductive sheet 817, and since the first conductive sheet 816 and the second conductive sheet 817 are electrically connected to the warning light 818, the circuit is turned on, and current passes through and activates the warning light 818, thereby reminding the operator to adjust it.
[0056] See also Fig.13 As shown, the adjustment assembly 6 includes a moving ring 61, a connecting box 62, a third rotating rod 63, a rotating handle 64, a gear 65 and a rack 66; the moving ring 61 is arranged on the connecting column 2, and the moving ring 61 is connected to the workbench 5; the connecting box 62 is installed on one side of the moving ring 61; the third rotating rod 63 is arranged in the connecting box 62, and one end of the third rotating rod 63 extends outward through the connecting box 62; the rotating handle 64 is arranged at the extended end of the third rotating rod 63; the gear 65 is arranged on the third rotating rod 63; the rack 66 is arranged on the connecting column 2, and the rack 66 is engaged with the gear 65.
[0057] When the height of the workbench 5 needs to be adjusted according to the height of the workpiece and the processing requirements, the third rotating rod 63 is driven to rotate by rotating the handle 64, and the rotation of the third rotating rod 63 further drives the gear 65 to rotate. Due to the meshing relationship between the gear 65 and the rack 66, the movable ring 61 is driven to move on the connecting column 2, and the connecting column 2 drives the workbench 5 to move, so that the height of the workbench 5 can be adjusted as required.
