Some embodiments of the present application will be described in detail below with reference to the drawings.

[0029] Please refer to Figure 1 , Figure 5 andFigure 7 The embodiment of the present application provides a tool setting member 10 applied to a detection device 100 including a tool setting instrument 20, and used for detecting abnormalities of a tool 30. The tool 30 can include a milling cutter, a drill, etc., and the abnormality detection items can include wear, broken blade, broken tool, wrong tool replacement, deflection, directional tool detection, etc. Obviously, this is not a limitation of the embodiment of the present application.

[0030] Please refer to Figure 1 , Figure 5 and Figure 7 In the embodiment of the present application, the tool setting member 10 has a first end surface 11 and a second end surface 12 arranged oppositely, the first end surface 11 is provided with a conical groove 14, the groove bottom of the conical groove 14 extends towards the second end surface 12, the second end surface 12 is used for abutting against a tool setting instrument 20, the groove wall of the conical groove 14 is used for abutting against the end of a tool 30, so as to cooperate with the tool setting instrument 20 to detect the tool 30, and the tool setting member 10 is also provided with a discharge channel 15 in communication with the groove bottom of the conical groove 14, and the discharge channel 15 is used for discharging the debris and cutting fluid in the conical groove 14.

[0031] Specifically, when the tool setting member 10 is used, the tool setting member 10 is installed on the tool setting instrument 20 and the second end surface 12 abuts against the tool setting instrument 20, so that the tool 30 can be inserted into the conical groove 14 from above the tool setting member 10 for detection.

[0032] Please refer to Figure 3 and Figure 4 When the tool 30 is detected for wear, broken blade and broken tool, before the tool 30 is used, a main shaft (not shown in the figure) first drives the tool 30 to move along the vertical direction towards the conical groove 14, since the tool 30 generally has three or four blades (not shown in the figure), by adjusting the position of the tool 30, at least two blades of the tool 30 abut against the groove wall of the conical groove 14, at this time, the tool 30 is approximately coaxial with the conical groove 14, and the tool setting instrument 20 records the distance between the end of the tool 30 away from the main shaft and the first end surface 11 as a standard value H1. When the tool 30 needs to be detected for wear, broken blade and broken tool after being used for a period of time, the main shaft (not shown in the figure) drives the tool 30 after being used to move along the vertical direction towards the conical groove 14 again, and at least two blades of the tool 30 abut against the groove wall of the conical groove 14, and the tool setting instrument 20 records the distance between the end of the tool 30 away from the main shaft and the first end surface 11 as an actual value H2. Since the change in the diameter of the tool 30 can be calculated by the change in the height of the tool 30 combined with the inclination angle α of the groove wall of the conical groove 14 through a trigonometric function, therefore, the change value in the diameter of the tool 30 can be calculated according to the difference between the standard value H2 and the actual value H1, and then the wear of the tool 30 can be judged, and whether the tool 30 has broken blade or broken tool can be judged.

[0033] When the wrong tool detection is performed on the tool 30, the process is substantially the same as the detection process of wear, breakage and broken tool of the tool 30, and the embodiments of the present application will not be described here.

[0034] When the tool 30 is subjected to the deflection detection, the process substantially includes the following steps:

[0035] The main shaft first drives the tool 30 to move along the vertical direction towards the conical groove 14 and reaches a safe height.

[0036] After the main shaft drives the tool 30 to rotate by a first fixed angle each time, the tool 30 continues to move from the safe height towards the groove wall of the conical groove 14, and when the tool 30 contacts the groove wall of the conical groove 14, the height of the tool 30 and the rotation angle are recorded. The heights of the tool 30 recorded multiple times are compared to obtain the highest point of the tool 30.

[0037] Specifically, the first fixed angle can be 30 degrees. After the main shaft drives the tool 30 to rotate by the first fixed angle each time, the tool 30 continues to move from the safe height towards the groove wall of the conical groove 14, and when the tool 30 contacts the groove wall of the conical groove 14, the height of the tool 30 and the rotation angle are recorded. Then the tool 30 is returned to the safe height, and when the tool 30 accumulates 180 degrees of rotation, the heights of the tool 30 recorded multiple times are compared to obtain the highest point of the tool 30.

[0038] On the basis of the rotation angle of the highest point, the main shaft drives the tool 30 to rotate by a second fixed angle each time, and the tool 30 continues to move from the safe height towards the groove wall of the conical groove 14. The second fixed angle is greater than the first fixed angle. When the tool 30 contacts the groove wall of the conical groove 14, the height of the tool 30 is recorded. The deflection value of the tool 30 is calculated according to the difference between the recorded heights of the tool 30.

[0039] Specifically, the second fixed angle can be 90 degrees. The rotation angle of the highest point is taken as the basis and recorded as 0 degrees. On the basis of the rotation angle of the highest point, the main shaft drives the tool 30 to rotate to 90 degree position, 180 degree position and 270 degree position respectively. At the 90 degree position, 180 degree position and 270 degree position, the main shaft drives the tool 30 to continue to move towards the groove wall of the conical groove 14 and make the tool 30 contact the groove wall of the conical groove 14, and the height of the tool 30 at the 90 degree position, 180 degree position and 270 degree position is recorded. Then the difference value of the height values of the tool 30 at the 0 degree position and 180 degree position is calculated, and the difference value of the height values of the tool 30 at the 90 degree position and 270 degree position is calculated. The maximum value between the two difference values is taken as the deflection value.

[0040] The deflection value is compared with the standard value to determine whether the deflection value of the tool 30 is qualified.

[0041] When the orientation tool (not shown in the figure) is detected and corrected, the following steps are generally included:

[0042] The spindle first drives the orientation tool to move along the vertical direction towards the conical groove 14 and reaches a safe height.

[0043] After the spindle drives the orientation tool to rotate a preset angle each time, the orientation tool continues to move from the safe height towards the groove wall of the conical groove 14, and when the orientation tool contacts the groove wall of the conical groove 14, the height of the orientation tool and the angle of rotation are recorded. The highest point of the orientation tool is obtained by comparing the heights of the orientation tool recorded multiple times.

[0044] Specifically, the orientation tool generally has an inclined tool tip (not shown in the figure), and the height of the orientation tool 30 is the highest when the tool tip contacts the groove wall of the conical groove 14. The preset angle can be 30 degrees. After the spindle drives the orientation tool to rotate a preset angle each time, the orientation tool continues to move from the safe height towards the groove wall of the conical groove 14, and when the orientation tool contacts the groove wall of the conical groove 14, the height of the orientation tool and the angle of rotation are recorded. Then the orientation tool is returned to the safe height, and when the orientation tool accumulates 180 degrees of rotation, the highest point of the orientation tool is obtained by comparing the heights of the orientation tool recorded multiple times.

[0045] According to the rotation angle of the orientation tool at the highest point, the orientation tool is corrected, that is, the height and rotation angle of the orientation tool at the highest point are the optimal tool setting height and tool setting angle when the orientation tool processes a workpiece.

[0046] In this way, the tool setting member 10 of the embodiment of the present application can be applied to multiple different detection items of the tool 30, thereby improving the efficiency of detecting the tool 30 and reducing the detection cost. In addition, by providing the discharge channel 15 on the tool setting member 10, which communicates with the groove bottom of the conical groove 14, the discharge channel 15 can quickly remove the debris and cutting fluid that falls from the tool 30 into the conical groove 14, thereby effectively avoiding the influence of the debris and cutting fluid accumulated in the conical groove 14 on the detection accuracy of the tool setting member 10, and further improving the accuracy of detecting the tool 30 using the tool setting member 10.

[0047] In the embodiment of the present application, the inclination angle of the groove wall of the conical groove 14 relative to the first end face 11 is 45 degrees. When the inclination angle of the groove wall of the conical groove 14 is 45 degrees, according to the principle of trigonometric function, the difference in height of the tool 30 is equal to the difference in diameter of the tool 30. Therefore, when the tool 30 is detected using the tool setting member 10, the difference in diameter of the tool 30 can be directly obtained according to the difference in height of the tool 30, which saves the calculation process, thereby improving the convenience and efficiency of detecting the tool 30 using the tool setting member 10.

[0048] In the embodiments of the present application, the diameter of the slot of the conical groove 14 ranges from 10 mm to 20 mm, and the conical groove 14 with the diameter range can be suitable for most tools 30 to extend into, thereby facilitating to improve the universality of the tool setting member 10 in detecting the tools 30.

[0049] Please refer to Figure 1 In an embodiment, the tool setting member 10 further has a first side surface 13 located between the first end surface 11 and the second end surface 12 and connected with the first end surface 11 and the second end surface 12 respectively, and the discharge channel 15 is arranged on the first side surface 13. By arranging the discharge channel 15 on the first side surface 13, the debris and cutting fluid in the conical groove 14 can be quickly discharged from one side of the tool setting member 10, and the connection between the second end surface 12 and the tool setting gauge 20 will not be affected.

[0050] In an embodiment, the first end surface 11 and the second end surface 12 are parallel, and the first side surface 13 is perpendicular to the first end surface 11 and the second end surface 12.

[0051] Please refer to Figure 1 In an embodiment, the axis of the conical groove 14 is located on the first side surface 13, and the discharge channel 15 is a gap formed at the connection between the groove wall of the conical groove 14 and the first side surface 13. In this way, the conical groove 14 is a semi-conical shape, the conical groove 14 is directly communicated with the first side surface 13, the size of the discharge channel 15 is larger, thereby further avoiding the influence of the debris and cutting fluid accumulated in the conical groove 14 on the detection accuracy of the tool setting member 10; in addition, this design structure is simple, which reduces the difficulty and processing cost of processing the tool setting member 10.

[0052] Please refer to Figure 5 and Figure 6 In another embodiment, the discharge channel 15 is a through hole, and the discharge channel 15 is arranged on the peripheral side wall of the tool setting member 10, thereby facilitating to quickly discharge the debris and cutting fluid in the conical groove 14 from the peripheral side of the tool setting member 10, and ensuring the integrity of the conical groove 14, when the tool setting member 10 is used to detect the wear, chipping and breakage of the tools 30, all the cutting edges of the tools 30 can be in abutment with the groove wall of the conical groove 14, thereby facilitating to improve the accuracy of the tool setting member 10 in detecting the wear, chipping and breakage of the tools 30.

[0053] In other embodiments, when there is a gap between the second end surface 12 and the tool setting gauge 20, the discharge channel 15 can also be arranged on the second end surface 12, which is not limited in the embodiments of the present application.

[0054] Please continue to refer to Figure 5 and Figure 6In another embodiment, the gage 10 is regular in shape and has an axis, and the axis of the conical groove 14 is collinear with the axis of the gage 10. Specifically, the cross section of the gage 10 can be square, hexagonal, or the like. By setting the gage 10 to be regular in shape and having an axis, and the axis of the conical groove 14 is collinear with the axis of the gage 10, the conical groove 14 is located in the middle of the gage 10, which is conducive to the conical groove 14 being formed on the gage 10 with a small size. In addition, when the gage 10 is installed on the tool setting gauge 20, the gage 10 will not tilt due to eccentricity, and when the groove wall of the conical groove 14 abuts against the tool 30, the tool setting gauge 20 can more accurately obtain the tool setting information, thereby improving the accuracy of detecting the tool 30 using the gage 10.

[0055] Referring to Figure 2 In an embodiment, the second end surface 12 is provided with a plurality of connection grooves 121 arranged at intervals, and the plurality of connection grooves 121 are used to accommodate glue for bonding the second end surface 12 and the tool setting gauge 20. Specifically, the gage 10 can be connected to the tool setting gauge 20 by means of glue bonding. When the second end surface 12 is bonded to the tool setting gauge 20 by glue, the plurality of connection grooves 121 can accommodate more glue, thereby improving the stability and firmness of the connection between the gage 10 and the tool setting gauge 20.

[0056] Referring to Figure 5 In another embodiment, the gage 10 is further provided with a plurality of connection holes 16 penetrating the first end surface 11 and the second end surface 12, and the plurality of connection holes 16 are arranged at intervals around the conical groove 14. Specifically, the gage 10 can be connected to the tool setting gauge 20 by means of a plurality of bolts (not shown) penetrating the plurality of connection holes 16, thereby improving the convenience of disassembling the gage 10 and the tool setting gauge 20.

[0057] In this embodiment, no matter how the gage 10 and the tool setting gauge 20 are connected, the flatness of the gage 10 needs to be corrected after the gage 10 and the tool setting gauge 20 are connected. Specifically, a plurality of points can be marked on the groove wall of the conical groove 14 by using a probe (not shown), and the plurality of points are located on the same plane. The center of the circle where the plurality of points are located is calculated according to the positions of the plurality of points, and whether the gage 10 is offset is determined according to the offset of the center.

[0058] In summary, the tool setting member 10 of the embodiment of the present application is provided with the conical groove 14 at the first end face 11, and the groove bottom of the conical groove 14 extends towards the second end face 12, so that the tool setting member 10 can be used to detect the tool 30 in multiple ways, thereby improving the detection efficiency of the tool 30 and reducing the detection cost. In addition, the discharge passage 15 is provided on the tool setting member 10 and communicates with the groove bottom of the conical groove 14, so that the discharge passage 15 can quickly discharge the debris and cutting fluid falling from the tool 30 into the conical groove 14, thereby effectively avoiding the influence of the debris and cutting fluid accumulated in the conical groove 14 on the detection accuracy of the tool setting member 10, and further improving the detection accuracy of the tool 30 by the tool setting member 10.
