Description

Technical Field

[0001] This utility model relates to the field of drilling and milling machines, and in particular to a four-axis CNC drilling and milling machine. Background Technology

[0002] A drilling and milling machine is a machine tool that combines drilling and milling functions. It is commonly used in metal processing and machinery manufacturing. A four-axis CNC drilling and milling machine adds a rotary axis. In addition to moving in the X, Y, and Z directions, the four-axis CNC machine tool can also rotate through the added A-axis, which makes the machining space larger and can complete more complex machining tasks.

[0003] Existing technologies, such as the utility model patent with publication number CN203557107U, disclose a four-axis CNC drilling and milling machine. This patent employs a base with an X-axis guide rail, a slide on the X-axis guide rail, a Y-axis guide rail on the slide, and a cutting device mounted on the Y-axis guide rail. The cutting device has a Z-axis guide rail, and a cutting mechanism on the Z-axis guide rail. The cutting mechanism includes a cutting head and a turbine device for driving the cutting head to rotate. The turbine device includes a turbine and a rotary arm motor. The turbine is mounted on the Z-axis guide rail, and the rotary arm motor is fixedly mounted on the cutting head. A worm gear is sleeved on the output shaft of the rotary arm motor, and the worm gear meshes with the turbine. The cutting head of this device can move in the X, Y, and Z axes and rotate from 0 to 180 degrees via the turbine device, enabling the machining of three to five sides of a workpiece in a single clamping operation. It can process products with complex structures, operates stably, provides precise machining, and has high efficiency.

[0004] The inventors discovered the following problems in their daily work when using a four-axis CNC drilling and milling machine: the orientation of the rotary axis in the A-axis device is not adjustable, resulting in low processing flexibility, inability to adjust according to the shape of the workpiece and processing requirements, and complex machine tool movement. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of the existing technology, such as the inability to adjust the angle of the A-axis device, which leads to low processing flexibility and low work efficiency.

[0006] To solve the above technical problems, this utility model provides a four-axis CNC drilling and milling machine, comprising: a base and an adjustment structure. A Y-axis device is mounted on the arc surface of the base. A frame is mounted on the upper surface of the Y-axis device. An X-axis device is mounted on the inner wall of the frame. A Z-axis device is mounted on the surface of the X-axis device. A spindle is mounted on the inner wall of the Z-axis device. A worktable is fixedly connected to the upper surface of the base. An A-axis device is mounted on the upper surface of the worktable via the adjustment structure. The upper surface of the worktable is provided with the adjustment structure, which includes two reserved slots. The two reserved slots are formed on the worktable. A fixed frame is fixedly connected to the bottom side of the inner wall of the slot. A positioning slot and a limiting slot are provided on the upper surface of the worktable.

Connecting blocks are fixedly connected to both sides of the A-axis device. An adjusting frame is slidably connected to the arc surface of the fixed frame. An adjusting rod is slidably connected to the inner wall of the adjusting frame. A connecting frame is fixedly connected to one end of the adjusting rod near the A-axis device. The arc surface of the connecting frame is slidably connected to the connecting block. A spring is sleeved on the surface of the adjusting rod. The two ends of the spring are fixedly connected to the adjusting frame and the connecting frame, respectively.

[0007] The effects achieved by the above components are as follows: the connecting frame, together with the connecting block, limits the two sides of the A-axis device; the positioning groove and the limiting groove limit the A-axis device in different postures, change the orientation of the rotation axis, and improve the processing flexibility.

[0008] Preferably, the two ends of the connecting frame near the A-axis device are arc-shaped.

[0009] The effect achieved by the above components is that the two ends of the connecting frame near the A-axis device are arc-shaped, which makes it easy for the connecting frame to slide into the connecting block.

[0010] Preferably, a pull ring is rotatably connected to the end of the adjusting rod away from the connecting frame.

[0011] The effect achieved by the above components is that the operating pull ring drives the adjusting rod to move, making it convenient for the user to move the adjusting rod.

[0012] Preferably, the adjusting rod is a rectangular rod.

[0013] The effect achieved by the above components is that the adjusting rod is a rectangular rod and will not rotate along the adjusting frame, resulting in high stability.

[0014] Preferably, an auxiliary structure is provided on one side of the workbench. The auxiliary structure includes a mounting frame, which is fixedly connected to the workbench. A mounting block is slidably connected to the inner wall of the mounting frame, and a collection box is fixedly connected to the upper surface of the mounting block. A screw is threaded into one side of the mounting frame.

[0015] The aforementioned components achieve the following effects: the operating screw allows for easy assembly and disassembly of the collection box, which is used to collect the debris generated during drilling and milling operations, making it convenient for users to manage the debris.

[0016] Preferably, the mounting block has an anti-slip groove on the side near the screw, and the inner wall of the anti-slip groove is fixedly connected with a number of anti-slip protrusions.

[0017] The effect achieved by the above components is to increase the friction between the screw and the mounting block through the anti-slip groove, thereby improving the limiting effect of the screw on the mounting block.

[0018] Preferably, two pulleys are rotatably connected to both sides of the inner wall of the mounting frame, and the arc surfaces of the two pulleys are slidably connected to the mounting block.

[0019] The effect achieved by the above components is to reduce the friction between the mounting frame and the mounting block by using pulleys, so that the mounting block moves more smoothly along the inner wall of the mounting frame.

[0020] Compared with related technologies, the four-axis CNC drilling and milling machine provided by this utility model has the following beneficial effects:

[0021] By setting an adjustment structure, the connecting frame and connecting block limit the two sides of the A-axis device, allowing for easy assembly and disassembly between the A-axis device and the worktable. The positioning groove and limiting groove limit the A-axis device in different postures. The A-axis device can be placed horizontally or vertically, and the orientation of the rotation axis of the A-axis device can be changed. It can be adjusted according to the shape of the workpiece and the processing requirements, improving processing flexibility, reducing the complexity of machine tool movement, and improving processing accuracy.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 5 This utility model provides a four-axis CNC drilling and milling machine, including: a base 1 and an adjustment structure 7. A Y-axis device 2 is installed on the arc surface of the base 1. A frame 3 is installed on the upper surface of the Y-axis device 2. An X-axis device 4 is installed on the inner wall of the frame 3. A Z-axis device 5 is installed on the surface of the X-axis device 4. A spindle 6 is installed on the inner wall of the Z-axis device 5. A worktable 9 is fixedly connected to the upper surface of the base 1. An A-axis device 10 is installed on the upper surface of the worktable 9 by means of the adjustment structure 7. The upper surface of the worktable 9 is provided with the adjustment structure 7. An auxiliary structure 8 is provided on one side of the worktable 9.

[0032] In the embodiments of this utility model, please refer to Figures 2 to 4The adjustment structure 7 includes two reserved slots 701, which are formed on the worktable 9. A fixed frame 702 is fixedly connected to the bottom inner wall of each reserved slot 701. A positioning slot 703 and a limiting slot 704 are formed on the upper surface of the worktable 9. The inner wall of the positioning slot 703 is slidably connected to the A-axis device 10. The inner wall dimension of the limiting slot 704 is adapted to the side dimension of the A-axis device 10. Connecting blocks 705 are fixedly connected to both sides of the A-axis device 10. An adjustment frame 706 is slidably connected to the arc surface of the fixed frame 702. An adjustment rod 707 is slidably connected to the inner wall of the adjustment frame 706. A connecting frame 708 is fixedly connected to one end of the adjustment rod 707 near the A-axis device 10. The arc surface of the connecting frame 708 is slidably connected to the connecting block 705. A spring 709 is sleeved on the surface of the adjustment rod 707. Both ends of 709 are fixedly connected to the adjusting frame 706 and the connecting frame 708 respectively. The connecting frame 708, together with the connecting block 705, limits the two sides of the A-axis device 10. The positioning groove 703 and the limiting groove 704 limit the A-axis device 10 in different postures, change the orientation of the rotation axis, and improve the processing flexibility. The two ends of the connecting frame 708 near the A-axis device 10 are arc-shaped, which makes it easy for the connecting frame 708 to slide into the connecting block 705. The end of the adjusting rod 707 away from the connecting frame 708 is rotatably connected to the pull ring 710. Operating the pull ring 710 drives the adjusting rod 707 to move, which makes it easy for the user to move the adjusting rod 707. The adjusting rod 707 is a rectangular rod, and the rectangular rod 707 will not rotate along the adjusting frame 706, so it has high stability.

[0033] In the embodiments of this utility model, please refer to Figure 5 The auxiliary structure 8 includes a mounting frame 81, which is fixedly connected to the worktable 9. A mounting block 82 is slidably connected to the inner wall of the mounting frame 81, and a collection box 83 is fixedly connected to the upper surface of the mounting block 82. A screw 84 is threaded into one side of the mounting frame 81. The screw 84 can be used to easily disassemble and assemble the collection box 83, which is used to collect the debris generated during drilling and milling operations, making it convenient for users to manage the debris. An anti-slip groove 85 is provided on the side of the mounting block 82 near the screw 84. Several anti-slip protrusions are fixedly connected to the inner wall of the anti-slip groove 85. The anti-slip groove 85 increases the friction between the screw 84 and the mounting block 82, making the limiting effect of the screw 84 on the mounting block 82 better. Two pulleys 86 are rotatably connected to both sides of the inner wall of the mounting frame 81. The arc surfaces of the two pulleys 86 are slidably connected to the mounting block 82. The pulleys 86 reduce the friction between the mounting frame 81 and the mounting block 82, making the mounting block 82 move more smoothly along the inner wall of the mounting frame 81.

[0034] The working principle of the four-axis CNC drilling and milling machine provided by this utility model is as follows: By setting the adjustment structure 7, first operate the adjustment rods 707 on both sides of the A-axis device 10, and move the two adjustment rods 707 simultaneously in a direction away from each other. During this process, the adjustment rods 707 move along the adjustment frame 706, and the adjustment rods 707 drive the connecting frame 708 to slide away from the connecting block 705. The spring 709 is in a compressed state. After the connecting frame 708 has moved far away from the connecting block 705, the limit on the A-axis device 10 is released, and the A-axis device 10 is moved upward, so that the A-axis device 10 slides away from the positioning groove 703. Then, the A-axis device 10 is rotated so that the A-axis device 10 is vertically placed into the limiting groove 704. Then, the operation... Two adjusting brackets 706 are moved along the reserved slot 701 and the fixed bracket 702 to the position of the limiting slot 704, so that the connecting bracket 708 is aligned with the connecting block 705. The adjusting rod 707 is released, and the compressed spring 709 gives the connecting bracket 708 an elastic force, so that the connecting bracket 708 moves into the connecting block 705, thereby fixing the position of the A-axis device 10. The two ends of the connecting bracket 708 near the A-axis device 10 are arc-shaped, which makes it easy for the connecting bracket 708 to slide into the connecting block 705. The operating pull ring 710 drives the adjusting rod 707 to move, which is convenient for the user to move the adjusting rod 707. The adjusting rod 707 is a rectangular rod and will not rotate along the adjusting bracket 706, so it has high stability.

[0035] By setting the auxiliary structure 8, when the debris in the collection box 83 is full, the screw 84 is rotated. The screw 84 moves away from the mounting block 82 along the mounting frame 81 with the help of the thread, and then contacts the limiting position of the mounting block 82. Then the collection box 83 moves upward, and the collection box 83 drives the mounting block 82 to slide upward away from the mounting frame 81. After the debris in the collection box 83 is emptied, the mounting block 82 is moved into the mounting frame 81 from top to bottom. The screw 84 is rotated in the opposite direction. The screw 84 moves closer to the mounting block 82 along the mounting frame 81 with the help of the thread. The screw 84 presses the mounting block 82, fixing the position of the collection box 83. The anti-slip groove 85 increases the friction between the screw 84 and the mounting block 82, making the limiting effect of the screw 84 on the mounting block 82 better. The pulley 86 reduces the friction between the mounting frame 81 and the mounting block 82, making the movement of the mounting block 82 along the inner wall of the mounting frame 81 smoother.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
