Description

Technical Field

[0001] The utility model relates to the technical field of knife sharpening racks, and particularly relates to a turning tool knife sharpening rack. Background Art

[0002] During the turning production process, the tool gradually wears out due to long-term use, so it needs to be regularly sharpened to ensure its performance. For example, the Chinese utility model patent with the application number CN201520043646.8 proposes a turning tool knife sharpening rack, which adjusts the sharpening angle of the tool by rotating and adjusting the first connecting pin, the second connecting pin and the third connecting pin.

[0003] However, this knife sharpening rack has an obvious defect: the adjustment directions of the first connecting pin and the second connecting pin are the same. Therefore, although the sharpening angle can be adjusted by rotating these three connecting pins, in fact, only two changes in the sharpening angle can be achieved. This limited adjustment range is not sufficient to meet the needs of all sharpening scenarios, and this limitation will lead to an inaccurate sharpening process, thereby affecting the final use effect of the tool.

Two groups of fixed seats 15 are fixedly connected vertically on the vertical end of the bracket 1. The worm 6 is rotatably installed on the two groups of fixed seats 15. Rotating the worm 7 drives the worm gear 6 to rotate. The worm gear 6 drives the transmission shaft 8, the transmission shaft 8 drives the rotating frame 5, and the rotating frame 5 drives the tool 14 to achieve the angular adjustment in the y-axis direction.

[0042] As Figure 2 and Figure 3 shown in the figure, the rotating shaft 9 is rotatably installed on the rotating frame 5. One end of the rotating shaft 9 is fixedly connected to the outer sleeve 11. The first bolt 10 and the rotating shaft 9 are symmetrically arranged on the rotating frame 5. The first bolt 10 is connected to the rotating frame 5 through a screw thread. One end of the first bolt 10 abuts against the outer sleeve 11. A positioning groove 1101 is opened on the outer sleeve 11 to cooperate with the first bolt 10. Rotating the rotating shaft 9 drives the outer sleeve 11 to rotate. The outer sleeve 11 drives the tool 14 to achieve the angular adjustment in the x-axis direction. Screw the first bolt 10 to press it against the positioning groove 1101 to position the outer sleeve 11.

One end of the second bolt 12 abuts against the surface of the tool 14. The third bolt (not shown in the figure) is screwed onto the outer sleeve through a thread. One end of the third bolt abuts against the surface of the inner sleeve 13. Rotating the inner sleeve 13 drives the tool 14 to achieve the angular adjustment in the z-axis direction.
