It is obvious that the drawings in the following description are only examples of the invention, from which other drawings can be obtained and from which other embodiments can be obtained without inventive effort for a person skilled in the art, and that the invention is not limited to these examples.
Referring to fig. 1, 2 and 3, a special knife sharpening device for a deburring tool according to an embodiment of the present invention includes a deburring tool holder 1, a first sharpening shaft 2 having one end fixed and the other end rotatably disposed around the fixed end, a second sharpening shaft 3 having one end fixed and the other end rotatably disposed around the fixed end, and a sharpening assembly 4. The polishing assembly 4 is arranged at the rotating end of the first polishing shaft 2, the second polishing shaft 3 is hinged with a connecting shaft 6, the connecting shaft 6 adopts a shaft sleeve type telescopic connecting shaft, the connecting shaft 6 can be lengthened in a drawing mode, the shaft length can be shortened in a pressing mode, but the connecting shaft 6 can be lengthened or shortened in a mode requiring larger force or a mechanical tool to regulate the length of the connecting shaft 6, so that the lengthening or shortening of the connecting shaft 6 becomes less random, the first polishing shaft 2 and the second polishing shaft 3 connected with the connecting shaft have better stability in use, and error in polishing angle adjustment is avoided.
The other end of the connecting shaft 6 is hinged with the first grinding shaft 2, when the second grinding shaft 3 rotates to the upper part of the cutter, the first grinding shaft 2 rotates along with the second grinding shaft through the connecting shaft 6, the length of the connecting shaft 6 is adjusted, the grinding end of the first connecting shaft 2 is positioned above the cutter point of the cutter, and the grinding angle is adjusted to grind the cutter clamped on the trimming cutter clamp 1.
The grinding machine further comprises a fixing assembly 7 which enables one end of each of the first grinding shaft 2 and the second grinding shaft 3 to be fixed, and the other end of each of the first grinding shaft 2 and the second grinding shaft 3 to rotate around the fixed end, and a fixing rod 8 which is used for fixing the first grinding shaft 2 and the second grinding shaft 3.
The fixing assembly 7 comprises a first nut 71 and a first bolt 72 with a non-threaded portion, a first bolt hole is respectively formed in one shaft end of the first grinding shaft 2 and one shaft end of the second grinding shaft 3, the first bolt 72 is sleeved in the first bolt hole and is in contact with the non-threaded portion of the first bolt 72, when the first nut 71 is not screwed to tightly fix the first grinding shaft 2 or the second grinding shaft 3, the first grinding shaft 2 or the second grinding shaft 3 can rotate, and after the first grinding shaft 2 is adjusted to a proper grinding angle, the first nut 71 is screwed again to tightly fix the first grinding shaft 2, so that the grinding angle is fixed.
And also comprises a cold water pipe 5 for assisting heat dissipation and flushing away waste.
The second polishing shaft 3 is provided with a third length adjuster 31 for adjusting the length of the second polishing shaft 3, the third length adjuster 31 is used for adjusting the length of the second polishing shaft 3 so that the second polishing shaft 3 can approach the cutter surface, but in the process of adjusting the length of the second polishing shaft 3 to the cutter surface, the first polishing shaft 2 is not necessarily close to the cutter surface, so that the first polishing shaft 2 also comprises a first length adjuster 21 and a second length adjuster 22 for adjusting the length of the first polishing shaft 2, the first length adjuster 21 is used for adjusting the position of the first polishing shaft 2 close to the cutter blade as far as possible and leaning against the cutter surface, but the adjustment length is avoided from being too large so that the cutter is deformed, the first length adjuster 21 should have proper adjustment precision, the adjustment precision should be higher than the adjustment precision of the third length adjuster 31 and lower than the adjustment precision of the second length adjuster 22, because the third length adjuster 31 is only used for coarse adjusting the length of the second polishing shaft 3 to the upper side of the cutter, the second length adjuster is not used for adjusting the cutter blade, and the cutter depth is not required to be higher than the first length adjuster 22, and the knife sharpening precision is determined to be at least 0 mm. For example, the adjusting bolt for adjusting the distance between the lenses in the two lens barrels in a microscope can adjust the magnification by adjusting the distance between the lenses by adjusting the extending of the shaft barrel with the lenses, and a similar structure can be used in the polishing device to adjust the length of the polishing shaft so as to accurately control the polishing precision and improve the repeated use rate of each trimming knife.
