Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-5 As shown, this utility model embodiment provides a deburring device for milling grooves, including a milling machine body 1, a deburring structure 2 and a driving component 3; a fixed seat 4 is installed on the top of the milling machine body 1.

The first lifting component 21 is installed on the bottom surface of the fixed base 4, the placement component 23 is installed on the bottom of the first lifting component 21, and several grinding components 22 are vertically inserted on the placement component 23.

[0024] The mounting component 23 includes a first fixing plate 231, a connecting plate 232, a second fixing plate 234, a positioning sleeve 236, a sliding plate 235, a limiting slide rod 233, and an elastic element 237. The first fixing plate 231 is horizontally installed at the bottom of the first lifting component 21. Several connecting plates 232 are vertically installed on the bottom surface of the first fixing plate 231. The second fixing plate 234 is horizontally installed at the bottom end of the connecting plate 232. The positioning sleeve 236 is disposed between the first fixing plate 231 and the second fixing plate 234. Furthermore, it is sleeved on the outside of the grinding component 22. The sliding plate 235 is fixedly installed on the outside of the positioning sleeve 236. The limiting slide rod 233 is evenly distributed in a circle on the outside of each positioning sleeve 236 and is slidably connected to the sliding plate 235. The elastic element 237 is sleeved on the outside of the limiting slide rod 233, with one end connected to the sliding plate 235 and the other end connected to the second fixed plate 234. The limiting slide rod 233 is vertically arranged, and the two ends of the limiting slide rod 233 are respectively connected to the first fixed plate 231 and the second fixed plate 234.

[0025] The driving component 3 includes an electric slide rail 31, a second lifting component 32, a driving component 33, and a fitting sleeve 34. The electric slide rail 31 is mounted on the top surface of the fixed base 4. The second lifting component 32 is vertically mounted on the sliding base of the electric slide rail 31. The driving component 33 is mounted on the bottom of the second lifting component 32. The fitting sleeve 34 is mounted on the output end of the driving component 33. The fitting sleeve 34 is used to fit the grinding component 22 so that the fitting sleeve 34 drives the grinding component 22 to rotate.

[0026] As a further description of the above scheme, the driving component 33 and the fitting sleeve 34 can move up and down under the action of the second lifting component 32. During the downward movement, the fitting sleeve 34 will fit into the grinding component 22 and play the role of pushing the grinding component 22 downward. When the grinding component 22 is squeezed, it will extend downward. In conjunction with the operation of the driving component 33, it can also drive the grinding component 22 to rotate, so that the grinding component 22 can deburr the workpiece.

[0027] Please see Figure 2-4 As shown, the grinding component 22 includes a grinding rod 221 and a fitting block 222. The grinding rod 221 is vertically arranged inside the positioning sleeve 236, and the fitting block 222 is installed at the center of the top surface of the grinding rod 221. The upper end shaft diameter of the grinding rod 221 is larger than the lower end shaft diameter, and the joints where the upper shaft diameter changes are all provided with arc-shaped chamfers; in order to prevent the grinding rod 221 from slipping out of the positioning sleeve 236.

[0028] Please see Figure 2-3 As shown, a wear-resistant pad 2361 that slides and adapts to the upper end of the grinding rod 221 is installed on the inner side of the positioning sleeve 236; the wear-resistant pad 2361 is designed to reduce friction and keep the grinding rod 221 rotating smoothly while avoiding contact between them and causing damage to the grinding rod 221 and the positioning sleeve 236.

[0029] Please see Figure 2-5 As shown, the bottom edge of the grinding rod 221 is provided with an outwardly convex rounded corner 2211 that is tangent to the side and bottom surface of the grinding rod 221, or an inwardly concave rounded corner 2212 that is perpendicular to the side and bottom surface of the grinding rod 221. The outwardly convex rounded corner 2211 is suitable for deburring the inner top wall edge of the groove structure on the workpiece, while the inwardly concave rounded corner 2212 is suitable for deburring the opening side edge of the groove structure on the workpiece.

[0030] As a further description of the above solution, the bottom and side surfaces of the grinding rod 221 can also be used for grinding and deburring the bottom and inner side walls of the groove structure, respectively.

[0031] Please see Figure 2-4 As shown, the interlocking block 222 is thicker at the bottom and thinner at the top, with a rounded top edge and a square bottom edge with rounded corners. The sides of the interlocking block 222 are evenly and gently curved surfaces. The inner wall of the interlocking sleeve 34 fits into the interlocking block 222. This facilitates the nesting and engagement of the interlocking sleeve 34 and the interlocking block 222 during the downward movement of the interlocking sleeve 34.

[0032] Please see Figure 1-2 As shown, a sliding groove 41 is vertically provided on the fixed base 4, and the width of the sliding groove 41 is greater than the diameter of the driving member 33; so that when the electric slide rail 31 drives the second lifting member 32 to move, the driving member 33 can slide in the fixed base 4 using the provided sliding groove 41.

[0033] Please see Figure 1-2 As shown, the first fixing plate 231 has a vertically formed insertion hole 2311 corresponding to the position of the grinding rod 221, and the size of the insertion hole 2311 is larger than the diameter of the upper end of the grinding rod 221. The second fixing plate 234 has a vertically formed through hole 2341 corresponding to the position of the grinding rod 221. The inner wall of the through hole 2341 is slidably adapted to the outer wall of the lower end of the grinding rod 221. The insertion hole 2311 facilitates the installation and removal of the grinding rod 221, and the through hole 2341 allows the grinding rod 221 to extend to the bottom of the second fixing plate 234.

[0034] Please see Figure 1 As shown, the milling machine body 1 includes a base 11, a support frame 12, a sliding component 15, and a milling component 14. The support frame 12 is vertically mounted on the base 11, the fixed seat 4 is mounted on the top surface of the support frame 12, the sliding component 15 is slidably mounted on the support frame 12 and is used to drive the workpiece to move, and the milling component 14 is mounted on the fixed seat 4.

[0035] Please see Figure 1As shown, the bottom of the grinding component 22 is higher than the bottom of the milling component 14 so as to prevent the grinding component 22 from obstructing the milling process when the milling component 14 is milling the workpiece.

[0036] As a further description of the above solution, when the first lifting component 21 is in the retracted state, the bottom position of the grinding component 22 is higher than the bottom position of the milling component 14. When deburring is required, the first lifting component 21 can be operated to move the placement component 23 to move the grinding component 22 downward, so that the bottom position of the grinding component 22 is lower than the bottom position of the milling component 14, thereby preventing the milling component 14 from obstructing the deburring process.

[0037] Please see Figure 1 As shown, the sliding component 15 includes a sliding table 151 and a worktable 152. The sliding table 151 is vertically slidably mounted on the support frame 12, and the worktable 152 is horizontally slidably mounted on the sliding table 151.

[0038] As a preferred embodiment of the above scheme, after the workpiece to be processed is installed on the worktable 152, the lateral position of the workpiece can be adjusted by sliding the workpiece on the worktable 152, the vertical position of the workpiece can be adjusted by sliding the sliding table 151 on the support frame 12, and the longitudinal position of the workpiece can be adjusted by sliding the worktable 152 on the sliding table 151.

[0039] The working process of the milling machine's groove deburring device described above is as follows: When using the milling machine groove deburring device, the workpiece must first be installed on the worktable 152, and the positions of the sliding table 151 and the worktable 152 should be adjusted according to the processing requirements so that the milling component 14 can process the workpiece. Then, the first lifting component 21 can be operated to adjust the height of the placement component 23, so that the grinding component 22 in the placement component 23 moves downward by one end until the bottom end of the grinding component 22 is below the bottom end of the milling component 14, so as to prevent the milling component 14 from obstructing the grinding. Then, the electric slide rail 31 is operated to drive the second lifting component 32, the driving component 33, and the fitting sleeve 34 to move so that the fitting sleeve 34 is positioned above the appropriate grinding component 22. After that, the second lifting component 32 is operated so that the driving component 33 drives the fitting sleeve 34 to move down. This allows the grinding component 22 to move down as a whole while ensuring that the fitting sleeve 34 is engaged with the fitting block 222 on the grinding component 22. This moves the grinding component 22 to the edge of the groove structure opening or the edge of the inner bottom wall of the groove structure on the workpiece. With the operation of the driving component 33, the grinding component 22 can rotate to perform grinding and deburring. By readjusting the position of the workpiece, the grinding component 22 can achieve the grinding and deburring of the edge of the groove structure on the workpiece.

[0040] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
