In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0042] Reference Figure 1 This utility model provides an auxiliary device for inspecting the appearance of a cutting tool, including a base 100, a first positioning groove 200, a positioning platform 300, and a second positioning groove 400.

[0043] Reference Figure 2 In some embodiments, a plurality of positioning blocks 500 are arranged side by side on the base 100. Each positioning block 500 has a first side surface 510, a second side surface 520, and a third side surface 530, with the second side surface 520 and the third side surface 530 being perpendicular to the first side surface 510. Two adjacent positioning blocks 500 form a first positioning groove 200 on the first side surface 510, which is used to position the circumferential cutting edge of a small-diameter tool. By forming the first positioning groove 200 on the first side surface 510 with two adjacent positioning blocks 500, the small-diameter tool can be placed horizontally. By rotating the handle of the small-diameter tool, the appearance of its circumferential cutting edge, such as edge wear and chipping, can be directly observed by a microscope.

[0044] It should be noted that small-diameter cutting tools are those with a shank diameter of less than 20mm, while large-diameter cutting tools are those with a shank diameter of more than 20mm.

[0045] Reference Figure 2 , Figure 3In some embodiments, multiple first positioning grooves 200 are arranged side by side, and the groove width D of the multiple first positioning grooves 200 increases progressively along their arrangement direction, as does the groove depth H of the multiple first positioning grooves 200, which facilitates microscope inspection of the circumferential cutting edge appearance of tools with different shank diameters. Furthermore, the groove depth H of the first positioning groove 200 increases synchronously with the groove width D of the first positioning groove 200, ensuring that the circumferential cutting edge of tools with different shank diameters can be placed within the first positioning groove 200. Simultaneously, when inspecting tools of different diameters, it is only necessary to move the tool to a suitable first positioning groove 200, eliminating the need for frequent replacement of matching auxiliary devices.

[0046] In some embodiments, the width D of the plurality of first positioning grooves 200 increases in an arithmetic progression along their arrangement direction, and the depth H of the plurality of first positioning grooves 200 increases in an arithmetic progression along their arrangement direction. Furthermore, the plurality of first positioning grooves 200 are divided into a first circumferential groove 210, a second circumferential groove 220, a third circumferential groove 230, and a fourth circumferential groove 240 along their arrangement direction; the width of the first circumferential groove 210 is less than 5 mm, and the depth of the first circumferential groove 210 is less than 2 mm; the first circumferential groove 210 is used to inspect the appearance of the circumferential cutting edge of the tool holder with a diameter less than 5 mm; the width of the second circumferential groove 220 is 5 mm to 10 mm, and the depth of the second circumferential groove 220 is 2 mm to 4 mm; the first circumferential groove 210 is used to inspect the appearance of the tool holder with a diameter less than 5 mm. The tool has a circumferential cutting edge with a shank diameter of 5mm to 10mm; the third circumferential groove 230 has a groove width of 10mm to 15mm and a groove depth of 4mm to 6mm; the first circumferential groove 210 is used to inspect the circumferential cutting edge with a shank diameter of 10mm to 15mm; the fourth circumferential groove 240 has a groove width of 15mm to 20mm and a groove depth of 6mm to 8mm; the first circumferential groove 210 is used to inspect the circumferential cutting edge with a shank diameter of 15mm to 20mm. By clearly defining the corresponding inspection range through the first circumferential groove 210, second circumferential groove 220, third circumferential groove 230, and fourth circumferential groove 240, quality inspectors can quickly match the corresponding first positioning groove 200 according to the tool shank diameter. The operation process is clear, reducing the risk of human error.

[0047] Specifically, the width D of the first positioning groove 200 increases in an arithmetic progression with a tolerance of 5mm, and the depth H of the first positioning groove 200 increases in an arithmetic progression with a tolerance of 2mm. The width of the first circumferential groove 210 is 5mm, and the depth is 2mm; the width of the second circumferential groove 220 is 10mm, and the depth is 4mm; the width of the third circumferential groove 230 is 15mm, and the depth is 6mm; the width of the fourth circumferential groove 240 is 20mm, and the depth is 8mm. In actual design, the width D and depth H of the first positioning groove 200 can be set according to actual needs.

[0048] Reference Figure 4 , Figure 5 In some embodiments, the second side 520 and the third side 530 of the positioning block 500 form a positioning platform 300 between themselves and the base 100. The positioning platform 300 is used to position the bottom of the tool shank, facilitating microscopic inspection of the appearance of the top teeth of the tool. Furthermore, the positioning platform 300 includes a first positioning surface 310 and a second positioning surface 320. The distance D1 between the first positioning surface 310 and the first side 510 is smaller than the distance D2 between the second positioning surface 320 and the first side 510. The first positioning surface 310 and the second positioning surface 320 can be adapted to low-length and high-length tools respectively, facilitating microscopic inspection of the appearance of the top teeth of both low-length and high-length tools. For example, because low-length tools are shorter, they are placed closer to the first side 510 on the first positioning surface 310; because high-length tools are longer, they are placed farther from the first side 510 on the second positioning surface 320, thereby enabling the inspection of the appearance of the top teeth of tools of different lengths and improving the applicability of the tool appearance inspection auxiliary device.

[0049] It should be noted that low-length tools are tools with a total length of 30mm to 60mm, while high-length tools are tools with a total length of 60mm to 120mm.

[0050] Reference Figure 4 In some embodiments, the distance D1 between the first positioning surface 310 and the first side surface 510 can be set to 30mm, and the distance D2 between the second positioning surface 320 and the first side surface 510 can be set to 60mm. Of course, in actual design, the distance D1 between the first positioning surface 310 and the first side surface 510 and the distance D2 between the second positioning surface 320 and the first side surface 510 can be designed according to actual needs.

[0051] Reference Figure 5 , Figure 6Specifically, two adjacent positioning blocks 500 form a third positioning groove 600 on the second side 520. The first positioning surface 310 is used to contact the bottom of the shank of the low-length tool, and the third positioning groove 600 is used to position the circumferential cutting edge of the low-length tool. During inspection, the shank of the low-length tool is placed in the third positioning groove 600, with the bottom of the shank in contact with the first positioning surface 310, exposing the cutting edge of the low-length tool. By rotating the shank of the low-length tool, the appearance of the top end teeth of the low-length tool can be observed under a microscope. At the same time, two adjacent positioning blocks 500 form a fourth positioning groove 700 on the third side 530. The second positioning surface 320 is used to contact the bottom of the shank of the high-length tool, and the fourth positioning groove 700 is used to position the circumferential cutting edge of the high-length tool. During testing, the shank of the high-length tool is placed in the fourth positioning groove 700, and the bottom of the shank of the high-length tool is in contact with the second positioning surface 320, so that the cutting edge of the high-length tool is exposed. The shank of the high-length tool is rotated to observe the appearance of the top end teeth of the high-length tool under a microscope.

[0052] In some embodiments, the widths of the plurality of third positioning grooves 600 are set in the same manner as the widths of the plurality of first positioning grooves 200, and the depths of the plurality of third positioning grooves 600 are set in the same manner as the depths of the plurality of first positioning grooves 200; the widths of the plurality of fourth positioning grooves 700 are set in the same manner as the widths of the plurality of first positioning grooves 200, and the depths of the plurality of fourth positioning grooves 700 are set in the same manner as the depths of the plurality of first positioning grooves 200. Specifically, the plurality of third positioning grooves 600 cooperate with the first positioning surface 310 to detect the appearance of the top teeth of tools with a short length and a tool shank diameter of 20mm or less; the plurality of fourth positioning grooves 700 cooperate with the first positioning surface 310 to detect the appearance of the top teeth of tools with a long length and a tool shank diameter of 20mm or less. The shorter cutting tool engages with the first positioning surface 310 via the third positioning groove 600, while the longer cutting tool engages with the second positioning surface 320 via the fourth positioning groove 700. This prevents blurring of the image caused by tool movement or displacement during inspection, ensuring a clear and stable image under the microscope and thus improving the accuracy of the inspection results. During inspection, quality inspectors simply need to place the tool shank into the corresponding third positioning groove 600 or fourth positioning groove 700 and ensure it contacts the positioning platform 300; no complex adjustment steps are required, improving inspection efficiency.

[0053] In some embodiments, the cross-sectional shape of the first positioning groove 200 is the same as that of the third positioning groove 600 and the fourth positioning groove 700. This identical cross-sectional shape ensures that the shank of a rotary tool can fit tightly against the groove wall in different testing scenarios, avoiding positioning deviations caused by differences in groove shape. For example, when inspecting the appearance of the circumferential cutting edge of a tool, the tool shank is placed in the corresponding first positioning groove 200; when inspecting the appearance of the top teeth of a tool, the tool shank is placed in the third positioning groove 600 or the fourth positioning groove 700, improving the positioning accuracy of the tool in different testing scenarios.

[0054] Reference Figure 1 , Figure 3 In some embodiments, the first positioning groove 200, the third positioning groove 600, and the fourth positioning groove 700 each include a first inclined surface 800 and a second inclined surface 900. The first inclined surface 800 is disposed on one of two adjacent positioning blocks 500, and the second inclined surface 900 is disposed on the other of two adjacent positioning blocks 500. The first inclined surface 800 and the second inclined surface 900 are axially symmetrical, that is, the cross-sectional shape of the first positioning groove 200, the third positioning groove 600, and the fourth positioning groove 700 is V-shaped. Through the constraint of the first inclined surface 800 and the second inclined surface 900, the axis of the tool always coincides with the symmetrical center line of the groove, reducing detection errors caused by positioning deviations.

[0055] In some embodiments, the tilt angle of the first inclined surface 800 is equal to the tilt angle of the second inclined surface 900. Specifically, the tilt angle of both the first inclined surface 800 and the second inclined surface 900 is 45°. Of course, in actual design, the tilt angles of the first inclined surface 800 and the second inclined surface 900 can be designed according to actual needs.

[0056] Reference Figure 1 , Figure 7 In some embodiments, the second positioning groove 400 is located on the side of the base 100 away from the positioning block 500. The second positioning groove 400 is used to inspect the appearance of the circumferential cutting edge of a large-diameter cutting tool. During inspection, the second positioning groove 400 is facing upwards, and the tool shank is placed inside the second positioning groove 400, exposing the cutting edge of the tool. The tool shank is rotated, thereby enabling observation of the appearance of the circumferential cutting edge of the large-diameter cutting tool under a microscope. The second positioning groove 400 cooperates with the first positioning groove 200 to meet the inspection needs of tools with different shank diameters, improving the versatility of the device.

[0057] In some embodiments, the width of the second positioning groove 400 is 25mm and the depth of the second positioning groove 400 is 10mm. Of course, in actual design, the width and depth of the second positioning groove 400 can be designed according to actual needs.

[0058] The method of using this utility model is as follows:

[0059] When the tool is a small-diameter, short-length tool, the first positioning groove 200 is set upwards, and the tool shank is placed in the corresponding first positioning groove 200, exposing the cutting edge of the tool. The tool shank is rotated, and the appearance of the circumferential cutting edge of the tool is observed under a microscope. Then, the tool shank is placed in the corresponding third positioning groove 600, and the bottom of the tool shank is in contact with the first positioning surface 310, exposing the cutting edge of the tool. The tool shank is rotated, and the appearance of the top end teeth of the tool is observed under a microscope.

[0060] When the tool is a small-diameter, high-length tool, the first positioning groove 200 is set upwards, the tool shank is placed in the corresponding first positioning groove 200, exposing the cutting edge of the tool, the tool shank is rotated, and the appearance of the circumferential cutting edge of the tool is observed under a microscope; then, the tool shank is placed in the corresponding fourth positioning groove 700, and the bottom of the tool shank is in contact with the second positioning surface 320, exposing the cutting edge of the tool, the tool shank is rotated, and the appearance of the top end teeth of the tool is observed under a microscope.

[0061] When the tool is a large-diameter tool, set the second positioning groove 400 upwards, place the tool shank in the corresponding second positioning groove 400 to expose the cutting edge of the tool, rotate the tool shank, and observe the appearance of the circumferential cutting edge of the tool under a microscope.

[0062] In this embodiment, the circumferential cutting edge of the tool can be positioned through the first positioning groove 200 and the second positioning groove 400, and the bottom of the tool shank can be positioned through the positioning platform 300. When using the auxiliary microscope of this application for inspection, not only can the appearance of the circumferential cutting edge and the appearance of the top end teeth of the tool be inspected, but also tools of different size ranges can be inspected. Compared with the traditional fixed-size V-block, this embodiment can adapt to tools of different specifications through the same auxiliary device. During inspection, there is no need to frequently change the matching V-block, which can simplify the operation process and improve the inspection efficiency.

[0063] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
