[0015] 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.

[0016] Example 1 Please see Figure 1-7This utility model provides a technical solution: a moving milling device, including a support base 1 for mounting the milling device and a fixed base 2 disposed on the support base 1 for placing a milling workpiece 3, and further including: a moving unit 4, adjustablely disposed on the support base 1 for adjusting the installation position of the milling unit 5; a positioning unit 6 disposed on the moving unit 4 for positioning the processing position of the milling unit 5; and an adjusting component 54 disposed on the moving unit 4 and connected to the positioning unit 6 for adjusting the installation position of the positioning unit 6. The milling unit 5 includes a motor 51 disposed on the moving unit 4, a rotating shaft 52 disposed at the power output end of the motor 51, and a milling cutter 53 disposed on the rotating shaft 52.

[0017] It should be noted that during operation, the workpiece 3 to be processed is placed on the fixed base 2 and fixed to the fixed base 2. When milling is required on the workpiece 3, the operator holds the moving unit 4 and starts the moving unit 4 to move on the support base 1. By adjusting the position of the moving unit 4 in the X and Y directions on the support base 1, the positioning unit 6 is aligned with the positioning groove 201 on the fixed base 2, so that the milling unit 5 is aligned with the milling position on the workpiece 3. Then, the moving unit 4 is pressed down to move it down, so that the milling cutter 53 is aligned with the milling position on the workpiece 3. Then, the motor 51 is turned on, and the milling cutter 53 is driven to rotate through the rotating shaft 52 to mill the workpiece 3. When the milling position of the workpiece 3 changes, the installation position of the positioning unit 6 can be adjusted by adjusting the component 54. The setting of the positioning unit 6 can adjust the position of the milling unit 6. The machining position of milling unit 5 is locked. During the milling process, even a slight deviation in position may lead to problems such as workpiece 3 being out of size or having substandard surface roughness. The positioning unit 6 acts like a ruler to ensure that milling unit 5 can accurately reach the predetermined machining position each time, controlling the machining error within a very small range, thereby significantly improving the machining accuracy of workpiece 3 and meeting the manufacturing requirements of parts. The adjustment component 54 is connected to the positioning unit 6, allowing the installation position of the positioning unit 6 to be flexibly adjusted according to the actual machining situation. Workpieces 3 of different shapes and sizes may require different machining positions. Through the adjustment component 54, the operator can quickly and accurately adjust the positioning unit 6 to the appropriate position to adapt to diverse machining tasks, ensuring that each workpiece 3 can be precisely machined, and further improving the overall machining accuracy.

[0018] In one embodiment, the support base 1 includes: a base plate 11, which is square-shaped and provides installation space for the milling equipment; side plates 13, which are fixed to the top of the base plate 11; a first slide rail 14, which is fixed between the two side plates 13 and is used to adjust the position of the milling unit 5X in the X direction; a slider 15, which is sleeved on the first slide rail 14; a second slide rail 16, which is disposed between the two sliders 15 and is used to adjust the position of the milling unit 5Y in the Y direction; a mounting platform 17, which is sleeved on the second slide rail 16; and a slide table 18, which is disposed on both sides of the mounting platform 17 and connected to the moving unit 4 and is used to adjust the position of the milling unit 5Z in the Z direction. The lower end of the base 11 is provided with support legs 12 for supporting the base 11.

[0019] This design is for reference. Figure 1-7 The rectangular base plate 11 provides a stable foundation installation space for the entire equipment. On this basis, the first slide rail 14, fixed between the two side plates 13, provides a precise track for the position adjustment of the milling unit 5 in the X direction. The slider 15 slides smoothly on the first slide rail 14, which can ensure the movement of the milling unit 5 in the X direction and effectively reduce the processing error caused by position deviation, so that the dimensional accuracy of the workpiece 3 in the horizontal direction can be reliably guaranteed. The second slide rail 16, set between the two sliders 15, realizes the flexible adjustment of the milling unit 5 in the Y direction. The mounting table 17 is fitted on the second slide rail 16 and can move smoothly with the slider 15 in the Y direction. During the processing, the position of the milling unit 5 in the Y direction can be precisely controlled, further improving the accuracy and consistency of the processing. The slide table 18 is set on both sides of the mounting table 17 and connected to the moving unit 4, providing stable support and precise control for the position adjustment of the milling unit 5 in the Z direction. Through the lifting and lowering movement of the slide table 18, the distance between the milling unit 5 and the workpiece 3 can be accurately adjusted to realize the processing of workpieces 3 of different thicknesses, thereby improving the processing accuracy of the workpiece 3.

[0020] In one embodiment, the moving unit 4 includes: a mounting frame 41 disposed on the outside of the mounting table 17 for mounting the milling unit 5; and a sliding plate 42 disposed on the inside of the mounting frame 41 and slidably connected to the sliding table 18.

[0021] With this design, the mounting bracket 41 is located on the outside of the mounting platform 17, providing a stable mounting platform for the milling unit 5. The slide plate 18 is located on the inside of the mounting platform 17 and is slidably connected to the slide table 42. This design further enhances the overall stability of the moving unit 4. As a key component on the support base 1 for adjusting the Z-direction position of the milling unit 5, the slide table 18 allows the slide plate 42 to slide smoothly along the slide table 18 during the movement of the milling unit 5. This effectively avoids swaying and offset caused by unilateral force or unstable movement, ensuring the accuracy and stability of the milling unit 5's movement in the Z-direction.

[0022] In one embodiment, an elastic element 19 is provided between the inner top wall of the mounting bracket 41 and the mounting platform 17. The elastic element 19 is made of a damped spring or an elastic pad.

[0023] This design is for reference. Figure 2 ,as well as Figure 4 During the milling process, as the mounting bracket 41 moves downward, it will compress the elastic element 19, causing the elastic element 19 to undergo elastic deformation. After the milling of the workpiece 3 is completed, the mounting bracket 41 is released, and the elastic element 19 can drive the mounting bracket 41 to move upward and reset, preparing for the next milling of the workpiece 3.

[0024] In one embodiment, the positioning unit 6 includes a first probe 61, which is disposed at the lower end of the mounting bracket 41 and is used to position the milling position of the milling unit 5.

[0025] This design is for reference. Figure 1-4 The first probe 61 is installed at the lower end of the mounting bracket 41. The distance between the first probe 61 and the milling cutter 53 is the same as the distance between the position of the milling point on the workpiece 3 and the positioning groove 201. When the first probe 61 is aligned with the positioning groove 201, the milling cutter 53 is aligned with the milling point on the workpiece 3, further improving the positioning accuracy.

[0026] In one embodiment, the adjustment assembly 54 includes: a fixed frame 541 disposed at the lower end of the mounting frame 41; a screw 542 disposed on the fixed frame 541; a lead screw sleeve 543 threadedly connected to the screw 542 and connected at its bottom to the first probe 61; a guide rod 544 disposed on the fixed frame 541 and connected to the lead screw sleeve 543 for guiding the lead screw sleeve 543; a turntable 545 disposed on one side of the screw 542; and a locking member 546 disposed on the turntable 545 and abutting against the fixed frame 541 for fixing the position of the screw 542.

[0027] This design is for reference. Figure 3The screw 542 and the lead screw sleeve 543 form a helical transmission pair. Utilizing the high precision of helical transmission, when the screw 542 is rotated, the lead screw sleeve 543 can move precisely linearly along the screw 542. Since the bottom of the lead screw sleeve 543 is connected to the first probe 61, the installation position of the first probe 61 can be adjusted. The guide rod 544 is connected to the lead screw sleeve 543, providing guidance for the movement of the lead screw sleeve 543. During the movement of the lead screw sleeve 543 along the screw 542, the guide rod 544 can prevent the lead screw sleeve 543 from rotating or deviating, ensuring that it always moves along a predetermined straight line. This further guarantees the first... The accuracy of the probe 61 movement reduces the positioning error caused by the movement deviation of the lead screw sleeve 543, and improves the reliability of positioning. The turntable 545 is set on one side of the screw 542. The operator can manually rotate the turntable 545 to drive the screw 542 to rotate, thereby adjusting the position of the first probe 61. The locking member 546 is set on the turntable 545 and abuts against the fixed frame 541. After the operator adjusts the first probe 61 to the appropriate position, he only needs to operate the locking member 546 to make it abut tightly against the fixed frame 541 to quickly fix the position of the screw 542, thereby locking the position of the first probe 61.

[0028] Example 2 In one embodiment, the positioning unit 6 further includes a second probe 62, which is disposed at the lower end of the mounting bracket 41 and symmetrically arranged about the milling unit 5.

[0029] This design is for reference. Figure 5-7 The second probe 62 is symmetrically arranged about the milling unit 5, and can measure and position the workpiece 3 from two different directions. At this time, two positioning slots 201 are also set on the corresponding fixed seat 2. This positioning method can obtain more comprehensive workpiece 3 position information. Compared with single probe positioning, it reduces the positioning error caused by factors such as uneven surface and irregular shape of workpiece 3, thereby improving the positioning accuracy of milling unit 5.

[0030] Example 3 In one embodiment, a dust collection unit 7 is provided on one side of the mounting platform 17. The dust collection unit 7 includes an adjustable equipment box 71 for storing dust collection equipment, a flexible connecting pipe 72 and a suction pipe 75 located at the lower end of the equipment box 71, a camera 73 located inside the connecting pipe 72, and an LED light 74 located inside the connecting pipe 72 and outside the camera 73. An air outlet 7201 is provided between the camera 73 and the connecting pipe 72. A display 8 is provided on the side plate 13.

[0031] This design is for reference. Figure 8-9When cutting workpiece 3, adjust the installation angle between equipment box 71 and mounting table 17. The inside of equipment box 71 is used to store negative pressure components and control equipment. Open camera 73 and negative pressure components to allow air to blow inside connecting pipe 72 and suction pipe 75 to suck air. This allows dust and impurities generated during milling to be absorbed by suction pipe 75, and the air outlet 7201 in connecting pipe 72 blows out the dust that enters connecting pipe 72, preventing dust from accumulating on camera 73 and affecting its performance. The camera 73 captures the milling process, and the LED light 74 provides good illumination, making it easy to observe the milling process of the workpiece 3. The installation angles of the connecting pipe 72 and the suction pipe 75 can be adjusted according to the actual processing conditions, so that the air outlet 7201 and the air inlet of the suction pipe 75 are aligned with the processing point of the workpiece 3, further improving the dust absorption efficiency. The display 8 is electrically connected to the camera 73, which can project the milling process captured by the camera 73 onto the display 8, making it convenient for the staff to observe the milling equipment's processing of the workpiece 3.
