Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of machining equipment, and particularly relates to a drilling machine tool supporting rapid transposition. BACKGROUND

[0002] In the design of existing drilling machine tools, traditional single-station drilling machine tools can usually process only one workpiece at a time, and a next workpiece to be processed needs to be manually replaced after a workpiece is completed. This operation mode is not only inefficient, but also prone to human error, affecting the processing precision. In addition, the positioning system of the traditional machine tool often relies on simple manual adjustment or semi-automatic control system, and it is difficult to realize micron-level position control, which cannot meet the needs of modern manufacturing industry for complex shapes and high-precision parts.

[0003] With the improvement of industrial automation level, the market has put forward higher requirements for drilling machine tools that are efficient, flexible and can process a variety of workpieces of different sizes and shapes.

[0004] However, although the multi-station drilling machine tool in the prior art can improve production efficiency to a certain extent, it still has deficiencies in workpiece transposition speed, operation convenience and the like.

[0005] For example:

[0006] Slow transposition speed: The multi-station drilling machine tool usually adopts a mechanical arm or other complex transposition mechanism, which needs a long time to complete the action in the transposition process, resulting in the extension of the overall processing cycle.

[0007] Limited processing precision: due to the complexity of the transposition mechanism and the cumulative error between the moving parts, the multi-station drilling machine tool may not be able to guarantee that each workpiece placement table can be positioned to the working position after transposition, thereby affecting the processing quality.

[0014] A connecting plate is connected to the first screw sliding table and the slide rail; and

[0015] A quick transposition mechanism comprises a mounting seat, a rotating rod, a rotating wheel, a nut, a disc and a driving assembly, the mounting seat is fixedly connected to the upper end of the connecting plate, the rotating rod is rotatably connected to the side end of the mounting seat, the rotating wheel is fixedly connected to one side end of the rotating rod, the nut is threadedly connected to the other side end of the rotating rod, and the disc is arranged on the rotating wheel.

[0016] As a preferred scheme of the utility model, the lower end of the disc is fixedly connected with a round rod, the circumferential surface of the round rod is fixedly connected with a first sprocket, the upper end of the connecting plate is fixedly connected with a motor, the output end of the motor is fixedly connected with a second sprocket, and the second sprocket is rotatably connected with the first sprocket through a toothed chain.

[0017] As a preferred scheme of the utility model, the upper end of the disc is fixedly connected with four machining workpiece placing tables, and the four machining workpiece placing tables are uniformly distributed on the upper end of the disc.

[0037] The connecting plate 5 is connected to the first screw rod sliding table 4 and the slide rail 3.

[0038] The quick position changing mechanism comprises a mounting seat 6, a rotating rod 7, a rotating wheel 8, a nut 9, a disc 10 and a driving assembly, the mounting seat 6 is fixedly connected to the upper end of the connecting plate 5, the rotating rod 7 is rotatably connected to the side end of the mounting seat 6, the rotating wheel 8 is fixedly connected to one side end of the rotating rod 7, the nut 9 is threadedly connected to the other side end of the rotating rod 7, and the disc 10 is arranged on the rotating wheel 8.

[0039] In the specific embodiment of the present application, the rack 1 serves as the basic structure of the entire machine tool, providing necessary support and stability to ensure the reliability and safety of the equipment during operation. The bottom plate 2 not only provides mounting positions for the slide rail 3 and the first screw rod sliding table 4, but also enhances the rigidity of the overall structure. The slide rail 3 is installed on the bottom plate 2, while the first screw rod sliding table 4 is used in cooperation with it, allowing the connecting plate 5 to move along a predetermined path. This combination achieves high-precision position control, which is crucial for ensuring the accuracy of drilling operations. The connecting plate 5 is connected to the first screw rod sliding table 4 and the slide rail 3, and carries and drives the disc 10 and the workpiece placing table 11 on it through the quick position changing mechanism on it. The design of the connecting plate 5 takes into account strength and lightweight to ensure smooth and efficient movement. The quick position changing mechanism: this mechanism is the core part of the present application, composed of a mounting seat 6, a rotating rod 7, a rotating wheel 8, a nut 9, a disc 10 and a driving assembly. Among them: the mounting seat 6 is fixed on the connecting plate 5 and is used to support other components. The rotating rod 7 is rotatably connected to one side of the mounting seat 6 through bearings and other elements, and can rotate around the shaft. The rotating wheel 8 is fixed to one end of the rotating rod 7 and rotates with the rotating rod 7. The nut 9 is threadedly connected to the other end of the rotating rod 7, and by adjusting the nut 9, the angle or position of the rotating rod 7 can be changed. The disc 10 is arranged above the rotating wheel 8 and is used to carry multiple evenly distributed machining workpiece placing tables 11. When it is necessary to change the machining position, the motor drives the rotating wheel 8, which in turn drives the disc 10 to rotate, so that the next workpiece to be machined is accurately moved to the working area.

[0040] For details, please refer to Figures 1-4 The lower end of the disc 10 is fixedly connected with a round rod 13, the circumferential surface of the round rod 13 is fixedly connected with a first sprocket 14, the upper end of the connecting plate 5 is fixedly connected with a motor 12, the output end of the motor 12 is fixedly connected with a second sprocket 15, and the second sprocket 15 is rotatably connected with the first sprocket 14 through a chain.

[0041] In this embodiment, the motor 12 serves as the power source, and the power output by the motor 12 is transmitted to the round rod 13 through the sprocket chain between the second sprocket 15 and the first sprocket 14, and then drives the disc 10 to rotate. This transmission mode can ensure stable and reliable power transmission, while reducing mechanical wear and improving the durability of the system. By adjusting the speed and direction of the motor 12, the rotation angle and speed of the disc 10 can be controlled, ensuring that each machining workpiece placement platform 11 can be accurately positioned to the working position. This not only improves the machining efficiency, but also ensures the consistency of the machining quality.

[0042] For details, please refer to Figures 1-4 , the upper end of the disc 10 is fixed with four machining workpiece placement platforms 11, and the four machining workpiece placement platforms 11 are evenly distributed on the upper end of the disc 10.

[0043] In this embodiment, the design of the four machining workpiece placement platforms 11 allows simultaneous loading of multiple workpieces, so that the machine tool can quickly switch to the next workpiece position to be machined in one position changing operation. The machining workpiece placement platforms 11 are evenly distributed on the disc 10, ensuring that the angle between each workpiece placement platform is equal, i.e. each workpiece placement platform is separated by 90 degrees.

[0044] For details, please refer to Figures 1-4 , the side end of the rack 1 is fixedly connected with a second screw sliding table 16, and the second screw sliding table 16 is connected with a third screw sliding table 17.

[0045] In this embodiment, by installing the second screw sliding table 16 at the side end of the rack 1 and connecting the third screw sliding table 17 thereto, multi-axis linkage in the X-axis, Y-axis and even Z-axis directions is achieved. This design allows the workpiece or tool head to move in multiple dimensions, thereby meeting the machining needs of complex-shaped workpieces.

[0046] For details, please refer to Figures 1-4 , the third screw sliding table 17 is connected with a fixed plate 18, and the side end of the fixed plate 18 is fixedly connected with a drilling device 19.

[0047] In this embodiment, the fixed plate 18 serves as a connecting piece to tightly combine the third screw sliding table 17 with the drilling device 19. This design not only provides stable support, but also ensures that the drilling device 19 will not deviate or vibrate during work. Since the third screw sliding table 17 itself can move along the second screw sliding table 16, and the fixed plate 18 is installed on the third screw sliding table, the position adjustment of the drilling device 19 in the X-axis and Y-axis directions can be realized by controlling the movement of the two screw sliding tables.

[0048] For details, please refer to Figures 1-4 , the height of the rack 1 is 1.5M.

[0049] In the embodiment: 1.5 meters of height is determined after ergonomics, suitable for most operators standing operating height when the operation. It not only ensures that the operator can easily access and operate the machine various control panel, button and tool, but also avoids the inconvenience brought by too low or too high, reduces the fatigue of operation.

[0050] The working principle and use process of the utility model are as follows: first, open the power, start the control system, enter the operation interface, select the corresponding program or set the parameters according to the processing task, use the second lead screw sliding table 16 and the third lead screw sliding table 17, move the drilling device 19 to the top of the first workpiece to be processed, ensure that the drill bit is aligned with the processing point, start the automatic processing cycle, the motor 12 drives the chain wheels 14 and 15 to rotate the disc 10 through the sprocket chain, and the workpiece on each processing workpiece placing table 11 is moved to the processing position in turn, the drilling device 19 carries out drilling operation according to the preset program, after a workpiece is completed, the disc 10 rotates to the next workpiece automatically, and the processing continues until all the workpieces are completed.

[0051] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing embodiments, or equivalent replacement to part of technical features.
