Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a dual-axis drilling and tapping machine that is easy to assemble. Background Technology

[0002] A dual-axis drilling and tapping machine is a machine tool equipped with two independent spindles, primarily used for drilling and tapping. Its advantage lies in its ability to perform two processes simultaneously, significantly improving production efficiency, and making it particularly suitable for mass production of high-precision parts. This equipment is widely used in industries such as electronics, automotive, and mold making to meet the processing needs of complex workpieces.

[0003] A dual-spindle drilling and tapping machine typically consists of a bed, a dual-spindle system, a servo drive system, a control system, a worktable, a tool magazine, and a cooling system. Its working principle involves programming the control system to drive the two spindles to move synchronously or independently. The high-speed rotating spindles drive drills or taps to drill or tap the workpiece. The two spindles can operate simultaneously or alternately, achieving a highly efficient and precise machining process, suitable for multi-process, high-volume production.

[0004] In existing technologies, due to high-speed cutting, continuous machining, and multiple processes being carried out simultaneously, the drill bit is subjected to large mechanical stress and thermal load, resulting in high drill bit wear during the use of dual-axis drilling and tapping machines. Furthermore, because the tool clamping system is precise and requires high-precision alignment, it is difficult to easily change drill bits on some drilling and tapping machines, leading to extended downtime, reduced production efficiency, and increased labor costs.

[0005] Therefore, to address the aforementioned problems, a dual-axis drilling and tapping machine that is easy to assemble is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a dual-axis drilling and tapping machine that is easy to assemble, aiming to improve the problem in the prior art that makes it difficult to conveniently change drill bits in some drilling and tapping machines.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The drilling mechanism includes motors, with the bottoms of two motors fixedly connected to both ends of the lifting platform, and the output end of the motors fixedly connected to a mounting assembly, the bottom of which is detachably connected to a drill bit.

[0010] The mounting assembly includes a mounting column, the top of which is fixedly connected to the output end of the motor. Multiple sliding columns are slidably connected inside the mounting column, and plug-in blocks are fixedly connected to adjacent ends of each sliding column.

[0011] As a further description of the above technical solution:

[0012] The mounting assembly also includes a pull ring, with one end of the pull ring fixedly connected to the other end of the sliding column. A limit plate is fixedly connected to the outer wall of the sliding column, and a spring is fixedly connected to the outer wall of the limit plate. The limit plate is slidably connected to the inside of the mounting column, and the other end of the spring is fixedly connected to the inside of the mounting column.

[0013] As a further description of the above technical solution:

[0014] The drill bit includes a threaded drill rod, the outer top of which is threaded to the inner bottom of the mounting post. A plug is fixedly connected to the top of the threaded drill rod, the outer side of which engages with the side of the plug-in block, and the top of which is detachably connected to the inner top of the mounting post.

[0015] As a further description of the above technical solution:

[0016] The drill bit has a spiral groove on its outer side, which is used to discharge the waste generated during drilling.

[0017] As a further description of the above technical solution:

[0018] The fixing mechanism includes a synchronization component and a clamping component. The top of the synchronization component is disposed at the bottom of the lifting platform, and the clamping component is slidably connected to the top of the worktable.

[0019] As a further description of the above technical solution:

[0020] The clamping assembly includes a clamping platform, the bottom of which is slidably connected to the top of the workbench. Multiple fixed cylinders are fixedly connected inside the clamping platform. Flexible contact heads are slidably connected inside the fixed cylinders. A piston plate is fixedly connected to one end of the flexible contact head. The piston plate is slidably connected inside the fixed cylinder. An air hole is opened at one end of the fixed cylinder. An air box is fixedly connected to the outer wall of the clamping platform. The air box communicates with the air hole.

[0021] As a further description of the above technical solution:

[0022] The synchronization component includes a lifting plate, the top of which is fixedly connected to the bottom of the lifting platform. Two rotating shafts are fixedly connected to both sides of the lifting plate. A rotating rod is rotatably connected to the outer side of the rotating shaft. A transmission pin is rotatably connected to the other end of the rotating rod. The far ends of the multiple transmission pins are respectively fixedly connected to the near side of two near clamping platforms.

[0023] As a further description of the above technical solution:

[0024] The bottom of each of the two clamping platforms is threaded with multiple set screws, and the bottom end of the set screws contacts the top of the worktable.

[0025] This utility model has the following beneficial effects:

[0026] 1. In this utility model, by pulling the pull ring, the sliding column is moved outward and the spring is compressed, causing the plug block to disengage from the drill bit plug. Then, the threaded drill rod is rotated to remove it from the mounting column. When installing a new drill bit, the threaded drill rod is screwed into the inner side of the bottom of the mounting column and the threaded connection is ensured to be secure. After releasing the pull ring, the spring pushes the sliding column to reset, causing the plug block to re-engage with the drill bit plug, thus completing the fixing of the drill bit. This achieves quick installation and removal of the drill bit, is easy to operate and has high stability, and significantly improves the maintenance efficiency and applicability of the equipment.

[0027] 2. In this utility model, the position of the clamping platform is adjusted by the set screw to make it contact the workpiece. Then, when the lifting platform descends, it drives the lifting plate to descend synchronously. The linkage between the rotating rod and the transmission pile causes the two middle clamping platforms to move in opposite directions, cooperating with the outer clamping platform to clamp the workpiece. After the flexible contact head on the clamping platform contacts the workpiece, it moves inward. The air box inflates the fixed cylinder through the air hole, pushing the piston plate and the flexible contact head to apply pressure to the workpiece, ensuring that the flexible contact head is in close contact with the workpiece surface, completing the adaptive clamping, realizing the stable fixation of the workpiece, adapting to workpieces of different shapes and sizes, and ensuring the accuracy and safety in the processing process.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Reference Figure 1 and Figure 2This utility model provides an embodiment of a dual-axis drilling and tapping machine that is easy to assemble, including a drill platform 1. A worktable 3 is detachably connected to the inner bottom of the drill platform 1 to facilitate transportation and on-site assembly. An L-shaped mounting plate 2 is detachably connected between the worktable 3 and the drill platform 1. The L-shaped mounting plate 2 serves as a connector, enhancing the structural stability between the drill platform 1 and the worktable 3, effectively dispersing vibrations during operation, and improving the overall rigidity of the equipment. A cylinder 4 is fixedly connected to the top of the drill platform 1. The cylinder 4 is pneumatically driven, featuring fast response and high control precision, ensuring that the lifting platform 6 maintains a stable movement trajectory during drilling. A telescopic rod 5 is fixedly connected to the output end of the cylinder 4. The lifting platform 6 is fixedly connected to the bottom of the telescopic rod 5. The lifting height of the lifting platform 6 can be controlled by adjusting the air pressure or stroke of the cylinder 4, thus adapting to the processing requirements of different workpieces. Drilling mechanisms 7 are provided at both ends of the lifting platform 6, and a fixing mechanism 8 is fixedly connected to the bottom of the lifting platform 6.

[0038] Reference Figure 2 , Figure 3 and Figure 5 The drilling mechanism 7 includes a motor 71. The bottoms of the two motors 71 are fixedly connected to both ends of the lifting platform 6. The output end of the motor 71 is fixedly connected to the mounting component 72. The bottom of the mounting component 72 is detachably connected to the drill bit 73. The design of the mounting component 72 makes it easier to replace the drill bit 73. Users can easily disassemble and install the drill bit 73, which improves the applicability and flexibility of the equipment.

[0039] Mounting assembly 72 includes a mounting post 721, the top of which is fixedly connected to the output end of a motor 71. The mounting post 721 connects the motor 71 to the drill bit 73 and transmits power from the motor 71 to the drill bit 73, causing it to rotate. Multiple sliding posts 722 are slidably connected inside the mounting post 721, allowing each sliding post 722 to move linearly within a certain range. A connecting block 723 is fixedly connected to each adjacent end of the sliding posts 722. The connecting block 723 engages with subsequent structures to clamp the drill bit 73, preventing it from loosening during rotation. A pull ring 724 is fixedly connected to each distal end of the sliding posts 722. The pull ring 724 allows the user to easily change the position of the sliding posts 722, thus releasing the drill bit 73 for easy replacement. A limiting plate 725 is fixedly connected to the outer wall of the sliding column 722. A spring 726 is fixedly connected to the outer wall of the limiting plate 725. The limiting plate 725 is slidably connected to the inside of the mounting column 721. The other end of the spring 726 is fixedly connected to the inside of the mounting column 721. The limiting plate 725 is used to limit the range of motion of the sliding column 722, thereby preventing the entire locking mechanism from slipping. The spring 726 is used to provide power for the reset of the sliding column 722.

[0040] The drill bit 73 includes a threaded drill rod 731. The top outer side of the threaded drill rod 731 is threadedly connected to the bottom inner side of the mounting post 721, thus ensuring the stability of the drill bit 73 during operation. A plug 732 is fixedly connected to the top of the threaded drill rod 731. The outer side of the plug 732 engages with the adjacent side of the connector block 723. This engagement design further enhances the fixing effect of the drill bit 73, preventing it from falling off during high-speed rotation. The top of the plug 732 is detachably connected to the inner top of the mounting post 721. A spiral groove is formed on the outer side of the drill bit 73. The spiral groove is used to discharge waste generated during drilling. The spiral groove design allows waste generated during drilling to be discharged in a timely manner, avoiding blockage of the drill bit 73 or a decrease in machining accuracy due to waste accumulation.

[0041] Reference Figure 2 , Figure 4 and Figure 6 The fixing mechanism 8 includes a synchronization component 81 and a clamping component 82. The top of the synchronization component 81 is located at the bottom of the lifting platform 6. The synchronization component 81 can perform preliminary clamping operations synchronously with the lifting platform 6 as it rises and falls, thereby ensuring the stability of the drilling process. The clamping component 82 is slidably connected to the top of the worktable 3. The clamping component 82 is used to adaptively adjust the clamping and locking operation during the preliminary clamping of the material by the synchronization component 81.

[0042] The clamping assembly 82 includes a clamping platform 821, the bottom of which is slidably connected to the top of the worktable 3. Multiple set screws 827 are threadedly connected to the bottom of two adjacent clamping platforms 821. The two outer clamping platforms 821 are fixed to the worktable 3 by sliding relative to each other via the set screws 827, thus accommodating workpieces of different sizes. The bottom end of the set screw 827 contacts the top of the worktable 3. Multiple fixed cylinders 822 are fixedly connected inside the clamping platform 821. Flexible contact heads 823 are slidably connected inside the fixed cylinders 822. The flexible contact design can adapt to irregular shapes on the workpiece surface, preventing workpiece deformation or damage due to excessive clamping force. Furthermore, the sliding of the flexible contact heads 823 within the fixed cylinders 822 adapts to workpieces with different outer shapes. A piston plate 824 is fixedly connected to one end of the flexible contact head 823. The piston plate 824 is slidably connected to the inside of the fixed cylinder 822. An air hole 825 is opened at one end of the fixed cylinder 822. An air box 826 is fixedly connected to the outer wall of the clamping table 821. The air box 826 inflates the fixed cylinder 822 through the air hole 825, thereby squeezing the piston plate 824 and making the flexible contact head 823 in close contact with the workpiece surface. The air box 826 is connected to the air hole 825, and the air pressure of the air box 826 is adjustable, allowing the user to flexibly adjust the clamping force according to the material of the workpiece and processing requirements.

[0043] The synchronization component 81 includes a lifting plate 811, the top of which is fixedly connected to the bottom of the lifting platform 6, so that the lifting plate 811 rises and falls synchronously when the lifting platform 6 is in the process of rising and falling. Two rotating shafts 812 are fixedly connected to both sides of the lifting plate 811, and the rotating shafts 812 are used to provide a rotational foundation for the subsequent structure. A rotating rod 813 is rotatably connected to the outer side of the rotating shaft 812. When the lifting platform 6 moves up and down, the lifting plate 811 drives the rotating rod 813 and the transmission pile 814 to move. The other end of the rotating rod 813 is rotatably connected to the transmission pile 814. The opposite ends of multiple transmission piles 814 are respectively fixedly connected to the opposite sides of two adjacent clamping platforms 821. The transmission piles 814 are used to transmit the movement of the rotating rod 813 to the two middle clamping platforms 821. Thus, when the lifting plate 811 moves downward, the two middle clamping platforms 821 move in opposite directions, thereby cooperating with the two outer clamping platforms 821 to adaptively clamp and fix the workpiece. When the lifting plate 811 moves upward, the opposite movement of the two middle clamping platforms 821 causes the entire clamping platform 821 to release the workpiece, making it convenient to change the workpiece.

[0044] Working principle: The user places the workpiece on the worktable 3. According to the size and shape of the workpiece, the position of the clamping table 821 is adjusted by the set screw 827 so that it contacts one side of the workpiece. The cylinder 4 is started. The output end of the cylinder 4 pushes the telescopic rod 5 to extend downward, which drives the lifting table 6 to move downward. During the descent of the lifting table 6, the motor 71 is started and transmits power to the drill bit 73 through the mounting component 72, so that the drill bit 73 rotates at high speed. During the drilling process, the spiral groove on the outside of the drill bit 73 will discharge the generated waste in time, avoiding the accumulation of waste that could cause the drill bit 73 to become blocked or reduce the processing accuracy.

[0045] When the lifting platform 6 descends, the lifting plate 811 descends synchronously due to the movement of the lifting platform 6. This movement drives the two transmission piles 814 on both sides to move through the rotation of the rotating rod 813 around the rotating shaft 812. Since the clamping table 821 is restricted by the worktable 3, the two middle clamping tables 821 move in opposite directions through the transmission action of the transmission piles 814 until they cooperate with the two outer clamping tables 821 to clamp the workpiece.

[0046] When the flexible contact head 823 on the clamping table 821 contacts the surface of the workpiece, the flexible contact head 823 moves into the fixed cylinder 822. At the same time, the air box 826 is opened, and the air box 826 inflates the fixed cylinder 822 through the air hole 825, which pushes the piston plate 824 and the flexible contact head 823 to move towards the workpiece. Thus, the workpiece is self-adaptively clamped through the close contact between the flexible contact head 823 and the outer surface of the workpiece.

[0047] When the drill bit 73 needs to be replaced or repaired, pull the pull ring 724 on the mounting post 721. The pull ring 724 moves the sliding post 722 outward, compressing the spring 726 and disengaging the connector block 723 from the plug 732 of the drill bit 73. Then, rotate the threaded drill rod 731 to loosen its threaded connection with the mounting post 721, allowing the drill bit 73 to be removed from the mounting post 721. Next, screw the threaded drill rod 731 of the new drill bit 73 into the inner bottom of the mounting post 721, ensuring a secure threaded connection. Then, release the pull ring 724. The spring 726 pushes the sliding post 722 back to its original position, causing the connector block 723 to re-engage with the plug 732 of the drill bit 73, thus securing the drill bit 73.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
