Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of automated processing, and in particular to a milling robot. Background Technology
[0002] Currently, milling robots refer to robots used for milling workpieces. These robots can move and operate automatically according to a predetermined program, offering advantages such as high precision, high speed, and high reliability. Their basic principle is that the robot receives and executes machining instructions generated by a CAD / CAM system to perform precise milling operations on the workpiece.
[0003] During milling, a large amount of iron filings and chips are generated. These fine chips not only have sharp edges but can also fly at high speeds, posing a risk of injury to operators. The chips can also enter the internal structure of the machine tool, damaging critical components and affecting the machine's accuracy and lifespan. The flying chips can also negatively impact the surface quality of machined parts. A chip shield can effectively block these chips, ensuring operator safety during machining. It prevents chips from entering the machine tool, protecting it from damage, and ensures that chips do not come into contact with the machined parts, thus improving the surface quality and accuracy of the parts. However, existing milling heads are located inside the chip shield, with only a small portion exposed for machining. Changing the milling head requires disassembling the entire chip shield, resulting in low operational efficiency. Furthermore, because the machining distance between the chip shield and the workpiece is fixed, some irregularly shaped workpieces may interfere with the chip shield during milling, rendering it unusable.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0033] like Figures 1 to 4 As shown, a preferred embodiment of the present invention provides a milling robot, comprising a robot body 10, a milling head 20, and a chip-proof assembly 30; wherein,
[0034] The anti-chip component 30 includes a base 50, a milling guard 70, and a lifting component 40. The base 50 is connected to the robot body 10, the lifting component 40 is connected to the base 50, and the milling guard 70 is connected to the lifting component 40 and is slidably connected to the base 50 through the lifting component 40.
[0035] The milling guard 70 includes a chip collection cavity 71 with a milling port 72. A milling head 20 is connected to a base and at least partly located within the chip collection cavity 71. The milling port 72 allows the milling head 20 to extend out of the chip collection cavity 71. The milling guard 70 has interconnected chip collection cavities 71 and milling ports 72. A chip collection pipe 31 communicates with the chip collection cavity 71. The milling head 20 is located in the chip collection cavity 71 and extends out through the milling port 72. A lifting assembly 40 is connected to a base 50, and the milling guard 70 is slidably connected to the base 50 via the lifting assembly 40.
[0036] The milling robot of this utility model includes a chip-proof component 30 comprising a base 50, a milling shield 70, and a lifting component 40. The milling head 20 is used to mill the workpiece 11. The base 50 is connected to the robot body 10. The milling shield 70, the lifting component 40, and the milling head 20 are all connected to the base 50. The robot body 10 drives the milling head 20 to process the workpiece 11 through the base 50. The milling shield 70 is connected to a chip collection pipe 31 for communication with a negative pressure system. The chip collection pipe 31 is connected to a chip collection cavity 71. The milling head 20 is located in the chip collection cavity 71 and extends out through the milling port 72 to process the workpiece 11. During the processing of the workpiece 11 by the milling head 20, the chip collection pipe 31 and the chip collection cavity 71 collect the chips near the milling port 72, preventing chips from splashing or remaining near the milling port 72. The base 50 is connected to a lifting assembly 40. The milling cover 70 is slidably connected to the base 50 via the lifting assembly 40, allowing the milling cover 70 to move relative to the milling head 20 in the height direction via the lifting assembly 40. When the milling head 20 needs to be replaced, the milling cover 70 moves upward away from the lower end of the milling head 20, exposing the milling head 20 from its machining opening, facilitating replacement. Simultaneously, when the workpiece 11 interferes with the milling cover 70, the milling cover 70 is moved away from the workpiece 11 via the lifting assembly 40, adjusting the distance between the workpiece 11 and the milling cover 70.
[0037] The milling guard 70 can be used for a wider range of workpieces 11 with different shapes.
[0038] The lower end of the milling head 20 is the machining end, used to perform milling on the workpiece 11.
[0039] Furthermore, such as Figures 3 to 4 As shown, the lifting assembly 40 includes a slide rail 41 and a lifting drive component 42. The lifting drive component 42 and the slide rail 41 are respectively fixed to the base 50. The slide rail 41 extends along the height direction of the base 50. The milling cover 70 is slidably connected to the slide rail 41, and the lifting drive component 42 is driveably connected to the milling cover 70. The milling cover 70 moves relative to the milling head 20 in the height direction via the lifting assembly 40. Specifically, the lifting assembly 40 includes a slide rail 41 and a lifting drive component 42. The slide rail 41 and the lifting drive component 42 are respectively connected to the base 50 to fix the slide rail 41 and the lifting drive component 42. The milling cover 70 is connected to the slide rail 41, and the slide rail 41 guides the milling cover 70, causing the milling cover 70 to move along the extension direction of the slide rail 41 when moving in the height direction. The lifting drive component 42 is used to drive the milling cover 70 to move along the height direction. The driving end of the lifting drive component 42 is connected to the milling cover 70, thereby driving the milling cover 70 to move along the height direction.
[0040] As one embodiment, such as Figures 3 to 4 As shown, the lifting drive component 42 is a cylinder. The lifting drive component 42 extends along the height direction, so that the driving direction of the lifting drive component 42 is consistent with the extension direction of the slide rail 41, making the transmission relationship between the lifting drive component 42 and the milling cover 70 simpler.
[0041] Furthermore, such as Figures 3 to 4 As shown, the anti-chip assembly 30 also includes a connecting seat 60. The connecting seat 60 includes a first end plate 61, a connecting plate 62, and a second end plate 63. The first end plate 61 and the second end plate 63 are respectively connected to the two ends of the connecting plate 62. The first end plate 61 is connected to the driving end of the lifting drive component 42, and the connecting plate 62 is slidably connected to the slide rail 41. The second end plate 63 is detachably connected to the milling guard 70. Through the connecting seat 60 composed of the first end plate 61, the connecting plate 62, and the second end plate 63, the milling guard 70 is connected to the lifting drive component 42 and the slide rail 41 respectively, making the overall structure of the anti-chip assembly 30 more stable. The detachable connection between the second end plate 63 and the milling guard 70 makes cleaning or replacing the milling guard 70 simple and quick, facilitating subsequent maintenance and replacement.
[0042] Furthermore, such as Figures 3 to 4As shown, the milling head 20 includes a milling head body 21, a milling drive 22, and a milling mounting base 23. The milling mounting base 23 is connected to the base 50, and the milling drive 22 is connected to the milling mounting base 23. The drive end of the milling drive 22 is connected to the milling head body 21 to drive the milling head body 21 to rotate for milling. During milling, the milling head body 21 extends out of the chip collection cavity 71 through the milling port 72. The milling head body 21 and the milling drive 22 are fixed on the base 50 by the milling mounting base 23. The milling mounting base 23 has sufficient rigidity and stability to withstand the cutting force and vibration during the milling process, ensuring the stable operation of the milling head 20. The milling drive 22 drives the milling head body 21 to rotate, and the milling head body 21 is used to process the workpiece 11.
[0043] Furthermore, such as Figures 3 to 4 As shown, the milling guard 70 is provided with a position adjustment port 73. The position adjustment port 73 and the milling machining port 72 are located at opposite ends of the milling guard 70 in the height direction. The position adjustment port 73, the chip collection cavity 71, and the milling machining port 72 are connected to form an adjustment channel. The milling drive 22 extends out of the chip collection cavity 71 from the position adjustment port 73. The milling head 20 moves relative to the milling guard 70 in the height direction within the adjustment channel. The milling drive 22 extending out of the adjustment channel from the position adjustment port 73 can reduce the volume of the milling guard 70. While meeting the requirement of preventing chip splashing, the milling guard 70 can be lightweight and reduce space occupation.
[0044] Furthermore, such as Figure 4 As shown, the shape of the outer peripheral surface of the milling fixture 23 corresponds to the shape of the position adjustment port 73. During milling, the milling fixture 23 is used to block the position adjustment port 73 to prevent fine chips from splashing out through the position adjustment port 73 during machining, thus ensuring the collection rate of fine chips.
[0045] Furthermore, such as Figures 2 to 4 As shown, a soft protective part 74 is connected to the outer surface of the milling guard 70 near the end of the milling head body 21, and the soft protective part 74 is arranged around the milling port 72. The soft protective part 74 faces the side of the milling body being processed, and the soft protective part 74 can prevent the workpiece 11 from directly contacting the milling guard 70, thus ensuring the processing quality of the workpiece 11.
[0046] As one embodiment, such as Figures 2 to 4 As shown, the soft protective part 74 is a rubber ring or a brush, which can prevent fine chips from splashing and avoid direct hard contact between the workpiece 11 and the milling guard 70, thus ensuring the machining quality of the workpiece 11.
[0047] Furthermore, such as Figures 1 to 4As shown, the base 50 includes a support frame 51 and a fixing plate 52. The support frame 51 is connected to the robot body 10, and the fixing plate 52 is connected to the side of the support frame 51 facing away from the robot body 10. The lifting assembly 40 and the milling fixing seat 23 are respectively connected to the fixing plate 52. The support frame 51, connected to the robot body 10, provides a stable support foundation for the entire system, ensuring that the milling head body 21 can maintain sufficient stability and accuracy during milling operations, thereby improving the machining quality. The lifting assembly 40 and the milling fixing seat 23 are respectively connected to the fixing plate 52. By dividing the base 50 into two parts, the support frame 51 and the fixing plate 52, the structure is modularized, facilitating assembly and maintenance. When a component is damaged or needs to be upgraded, it can be replaced individually.
[0048] Furthermore, such as Figure 4 As shown, the milling guard 70 is connected to a chip collection pipe 31 for communication with a negative pressure system. The chip collection pipe 31 is connected to the chip collection cavity 71. The lower end of the milling guard 70 is provided with a chip collection port 75, which is connected to the chip collection cavity 71. The chip collection pipe 31 is connected to the chip collection port 75. The chip collection port 75 is located at the lower end of the milling guard 70, shortening the distance to the milling machining port 72, making it easier for the chip collection pipe 31 to collect the flying chips at the machining site, and improving the chip collection rate.
[0049] Furthermore, such as Figures 3 to 4 As shown, the milling guard 70 has chip collection ports 75 on opposite sides, each connected to a chip collection pipe 31. The chip collection pipes 31 extend upwards, forming an angle α with the side of the milling guard 70, where α = 30°-60°. The two chip collection ports 75 of the milling guard 70 are connected to chip collection pipes 31, increasing the chip collection area and improving chip collection efficiency. The extension direction of the side of the milling guard 70 is the height direction, and the angle α between the axis of the chip collection pipe 31 and the height direction is set at 30°-60° to ensure smoother chip collection and discharge.
[0050] As one embodiment, the included angle α = 45°, which makes the collection and discharge of fine debris smoother.
[0051] As one embodiment, such as Figures 3 to 4 As shown, the milling guard 70 is provided with an observation window, which is connected to a transparent plate to facilitate observation of the chip collection.
[0052] In summary, this utility model embodiment provides a milling robot. The anti-chip component 30 includes a base 50, a milling shield 70, and a lifting component 40. The milling head 20 is used to mill the workpiece 11. The base 50 is connected to the robot body 10. The milling shield 70, the lifting component 40, and the milling head 20 are all connected to the base 50. The robot body 10 drives the milling head 20 to process the workpiece 11 through the base 50. The milling shield 70 is connected to a chip collection pipe 31 for communication with a negative pressure system. The chip collection pipe 31 is connected to the chip collection cavity 71. The milling head 20 is located in the chip collection cavity 71 and extends out through the milling port 72 to process the workpiece 11. During the processing of the workpiece 11 by the milling head 20, the chip collection pipe 31 and the chip collection cavity 71 collect the chips near the milling port 72, preventing chips from splashing or remaining near the milling port 72. The base 50 is connected to a lifting assembly 40. The milling cover 70 is slidably connected to the base 50 via the lifting assembly 40, allowing the milling cover 70 to move relative to the milling head 20 in the height direction via the lifting assembly 40. When the milling head 20 needs to be replaced, the milling cover 70 moves upward away from the lower end of the milling head 20, exposing the milling head 20 from its machining opening, facilitating replacement. Simultaneously, when the workpiece 11 interferes with the milling cover 70, the milling cover 70 is moved away from the workpiece 11 via the lifting assembly 40, adjusting the distance between the workpiece 11 and the milling cover 70, making the milling cover 70 suitable for workpieces 11 of more different shapes.
[0053] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
