Description

Technical Field

[0001] This application relates to the field of cutting tool inspection technology, and specifically to a cutting tool inspection device. Background Technology

[0002] When machining products using cutting tools in a machining center, issues such as incorrect tool selection or tool wear and chipping can occur, affecting the machining quality. Currently, manual visual inspection is commonly used to check the tools. However, this method is inefficient and struggles to detect radial runout and tool tip morphology, resulting in low accuracy. Summary of the Invention

[0003] In view of the above, it is necessary to propose a tool inspection device to improve the efficiency and accuracy of tool inspection.

[0004] This application provides a tool detection device, including a fixed component, a movable component, and a sensor. The movable component is slidably disposed on the fixed component along a first direction. The movable component has a first detection surface and a second detection surface. The first detection surface is perpendicular to the first direction, and the angle between the second detection surface and the first direction is an acute angle. The sensor is disposed on the fixed component and faces the movable component. When the periphery of the tool abuts against the first detection surface, the sensor detects the radial runout of the tool by sensing the moving distance of the movable component. When the tip of the tool abuts against the second detection surface, the sensor detects the shape of the tip of the tool by sensing the moving distance of the movable component.

[0005] The aforementioned tool detection device slides a movable component along a first direction onto a fixed component. The movable component has a first detection surface and a second detection surface for contacting the tool. A sensor is positioned on the fixed component, directly opposite the movable component. When it is necessary to detect the radial runout and tip shape of the tool, the tool is simply moved towards the first and second detection surfaces, with the tool's peripheral wall and tip contacting them respectively. The sensor then detects the moving distance of the movable component, accurately detecting the radial runout and tip shape based on this distance. Thus, the tool detection device of this embodiment achieves automatic detection of the radial runout and tip shape, improving detection efficiency. Furthermore, because the tool detection device of this embodiment can accurately detect the radial runout and tip shape, it improves the accuracy of tool detection.

[0006] In some embodiments, the movable component includes a movable member and an abutment member; the movable member is slidably disposed on the fixed component along the first direction; the abutment member is detachably disposed on the side of the movable member away from the fixed component, and both the first detection surface and the second detection surface are disposed on the abutment member.

[0007] Thus, by setting the abutment and the moving part to be detachably connected, and setting the first detection surface and the second detection surface on the abutment, it is convenient to quickly replace the abutment.

[0008] In some embodiments, the movable member has an inclined slot on the side away from the fixed component, and the angle between the extending direction of the slot and the first direction is an acute angle, and the abutment member is engaged in the slot.

[0009] Thus, by setting a slot to engage with the abutment and positioning the abutment, the convenience and accuracy of installing the abutment are improved.

[0010] In some embodiments, the abutment is made of tungsten steel.

[0011] Tungsten steel has the characteristics of wear resistance and high hardness. By setting the abutment parts to be made of tungsten steel, it is beneficial to improve the service life of the abutment parts.

[0012] In some embodiments, the movable member has a cleaning section located on one side of the abutment member, the cleaning section having a cleaning hole for blowing out gas to clean the blade.

[0013] Therefore, before inspecting the cutting tool, the tool can be moved to a position directly opposite the cleaning hole. The air blown out of the cleaning hole cleans the chips stuck on the tool, which can effectively avoid the chip stuck on the tool affecting the accuracy of the tool inspection results and help improve the processing quality of the product processed by the tool.

[0014] In some embodiments, the movable member has an insertion hole extending along the first direction on the side facing the fixed component, the sensing element extends into the insertion hole, and the tool detection device further includes a limiting member, the limiting member being inserted into the movable member along the second direction and extending into the insertion hole to abut against the sensing element, the limiting member being used to restrict the movement of the sensing element along the second direction, wherein the first direction and the second direction are perpendicular to each other.

[0015] Thus, by providing an insertion hole on the moving part, it is convenient to install the sensing element. By providing a limiting element to abut and restrict the movement of the sensing element along the second direction, it is beneficial to improve the accuracy of the sensing element in sensing the movement distance of the moving part, and in turn, it is beneficial to improve the accuracy of the tool detection device in detecting the tool.

[0016] In some embodiments, the tool detection device further includes an elastic element, the two ends of which are respectively connected to the fixing component and the hole wall of the insertion hole, and the elastic element drives the moving component back to its original position when the tool is disengaged from the first detection surface or the second detection surface.

[0017] Thus, by setting up an elastic element, when the tool inspection is completed and the tool is removed from the first or second inspection surface, the elastic element drives the moving part to return to its original position, thereby facilitating the tool inspection device to inspect the tool again.

[0018] In some embodiments, the insertion hole includes a stop hole and a receiving hole that are sequentially connected and coaxially arranged. The stop hole is located on the side of the movable member closer to the fixed component, and the diameter of the stop hole is larger than the diameter of the receiving hole. The sensing element passes through the stop hole and extends into the receiving hole. The limiting member is inserted into the movable member along the second direction and extends into the receiving hole to abut against the sensing element. The elastic element is sleeved on the sensing element, and both ends of the elastic element abut against the fixed component and the end of the stop hole closer to the receiving hole, respectively.

[0019] This facilitates the installation of the elastic element. In addition, the end of the stop hole near the receiving hole abuts against the elastic element, which can limit the movement of the elastic element, thereby improving the accuracy of the elastic element driving the moving part.

[0020] In some embodiments, the fixing component includes a fixing member and a waterproof member; the movable member is slidably covered by the fixing member along the first direction, the fixing member has a mounting hole extending along the first direction and facing the movable member, and the sensing member is disposed in the mounting hole; the waterproof member is connected to the end of the mounting hole away from the movable member, and the data line of the sensing member passes through the waterproof member and extends to the outside of the mounting hole.

[0021] In this way, by setting a waterproof component to seal one end of the mounting hole and allowing the data line of the sensor to pass through the waterproof component and extend to the outside of the mounting hole, it is possible to effectively prevent liquids such as cutting fluid from entering the mounting hole and affecting the normal operation of the sensor, thereby improving the stability of the tool detection device in detecting tools.

[0022] In some embodiments, the tool detection device further includes a support component connected to the fixed component to support the fixed component and the movable component.

[0023] In this way, by setting up support components to support the fixed components and the moving components, it is easy to quickly install the fixed components and the moving components into the machining center. Attached Figure Description

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows communication between components; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0032] Please see Figure 1 This application provides a tool detection device 100 for detecting tools. For ease of understanding and explanation, this application defines the first direction as... Figure 1 The X-axis direction is shown, and the second direction is... Figure 1 The Z-axis direction shown is perpendicular to the second direction. Obviously, this is not a limitation on the embodiments of this application.

[0033] Please see Figure 1 and Figure 2 The tool detection device 100 of this application embodiment includes a support component 10, a fixing component 20, a moving component 30, and a sensing element 40.

[0034] The support assembly 10 is connected to the worktable (not shown) of the machining center (not shown in the figure), and the fixing assembly 20 is connected to the end of the support assembly 10 away from the worktable of the machining center.

[0035] The movable component 30 is slidably disposed on the fixed component 20 along the first direction. The support component 10 supports the fixed component 20 and the movable component 30. The movable component 30 has a first detection surface 321 and a second detection surface 322. The first detection surface 321 is perpendicular to the first direction, and the angle between the second detection surface 322 and the first direction is an acute angle.

[0036] The sensor 40 is disposed on the fixed component 20 and faces the moving component 30. When the periphery of the tool abuts against the first detection surface 321, the sensor 40 detects the radial runout of the tool by sensing the moving distance of the moving component 30. When the tip of the tool abuts against the second detection surface 322, the sensor 40 detects the shape of the tip of the tool by sensing the moving distance of the moving component 30. The shape of the tip can be understood as at least one of the size of the tip R angle and the radial runout of the tip.

[0037] In this embodiment, the cutting tool can be mounted on the spindle of the machining center, the sensing element 40 can be a displacement sensor, and the data line 41 of the sensing element 40 can be connected to the machining center. The machining center is equipped with a detection program for detecting the radial runout of the cutting tool and the shape of the cutting tip.

[0038] When it is necessary to detect the radial runout of the tool, the spindle of the machining center drives the tool to move towards the first detection surface 321 and abuts the circumference of the tool against the first detection surface 321. Then, the spindle of the machining center drives the tool to rotate. Under the squeezing action of the circumference wall of the tool, the first detection surface 321 causes the moving component 30 to move towards the sensing element 40. The sensing element 40 senses the moving distance of the moving component 30. The detection program in the machining center calculates the radial runout of the tool based on the moving distance of the moving component 30 sensed by the sensing element 40, thereby determining whether the radial runout of the tool is accurate, and finally obtaining detection results such as whether the wrong tool was changed, whether the cutting edge of the tool is worn or chipped.

[0039] When the shape of the cutting tool tip needs to be detected, the spindle of the machining center moves the cutting tool towards the second detection surface 322, causing the cutting tool tip to abut against the second detection surface 322. Then, the spindle of the machining center rotates the cutting tool, and the second detection surface 322, under the pressure of the cutting tool tip, causes the moving component 30 to move towards the sensing element 40. The sensing element 40 senses the moving distance of the moving component 30. The detection program in the machining center calculates the shape of the cutting tool tip based on the moving distance sensed by the sensing element 40, thereby determining whether the shape of the cutting tool tip is accurate, such as whether the radius (R) angle of the cutting tool tip is accurate, whether the radial runout of the cutting tool tip is accurate, etc., and finally obtains detection results such as whether the wrong tool was changed, whether the cutting tool tip is worn or chipped. It should be noted that since the angle between the second detection surface 322 and the first direction is fixed, after the sensing element 40 senses the moving distance of the moving component 30 along the first direction, it can calculate the moving distance of the cutting tool tip pressing against the second detection surface 322 based on the angle, thereby calculating the shape of the cutting tool tip.

[0040] In some other embodiments, the support component 10 may not be provided, and the fixing component 20 may be directly fixed in the machining center by bolts or other connecting parts. This application does not specifically limit this.

[0041] In some other embodiments, the tool detection device 100 may also include a controller (not shown), which is electrically connected to the sensor 40 and is equipped with a detection program for detecting the radial runout of the tool and the shape of the tool tip. The controller calculates the radial runout of the tool and the shape of the tool tip based on the sensing information of the sensor 40. This application embodiment does not specifically limit this.

[0042] In this embodiment, the support assembly 10 includes a base 11 and a bracket 12. The base 11 is used to connect to the worktable of the machining center, and a U-shaped connecting groove 111 is provided on the base 11 to facilitate fixing the base 11 to the worktable of the machining center with bolts. One end of the bracket 12 is connected to the base 11, and the other end of the bracket 12 is connected to the fixing assembly 20 to facilitate supporting the fixing assembly 20.

[0043] Please refer to the following: Figure 3 In this embodiment, the fixing component 20 includes a fixing member 21 and a waterproof member 22. The fixing member 21 is connected to the bracket 12 of the supporting component 10. The moving component 30 is slidably covered by the fixing member 21 along the first direction. The fixing member 21 has a mounting hole 215 extending along the first direction and facing the moving component 31. The mounting hole 215 passes through both ends of the fixing member 21. The sensing element 40 is disposed in the mounting hole 215. The waterproof member 22 is connected to the end of the mounting hole 215 away from the moving component 31. The data line 41 of the sensing element 40 passes through the waterproof member 22 and extends to the outside of the mounting hole 215. Since the tool detection device 100 of this application can be installed in a machining center, and the machining center needs to use liquids such as cutting fluid when processing products, the entry of liquids such as cutting fluid into the mounting hole 215 may cause the sensor 40 to malfunction. By setting a waterproof component 22 to block one end of the mounting hole 215 and allowing the data line 41 of the sensor 40 to pass through the waterproof component 22 and extend to the outside of the mounting hole 215, it is possible to effectively prevent liquids such as cutting fluid from entering the mounting hole 215 and affecting the normal operation of the sensor 40, thereby improving the stability of the tool detection device 100 in detecting tools.

[0044] In this embodiment, the waterproof component 22 can be threadedly connected to the mounting hole 215, which helps to improve the convenience of assembling and disassembling the waterproof component 22.

[0045] In this embodiment, the fastener 21 includes a first assembly block 211, a second assembly block 212, a first connecting block 213, and a second connecting block 214. Both the first assembly block 211 and the second assembly block 212 are generally columnar. The first assembly block 211 and the second assembly block 212 are sequentially arranged along a first direction and abut against each other. The first connecting block 213 is located below the first assembly block 211 and the second assembly block 212 and is connected to them. The side of the first connecting block 213 facing away from the first assembly block 211 and the second assembly block 212 is also connected to the bracket 12 of the support assembly 10. The second connecting block 214 is located above the first assembly block 211 and the second assembly block 212 and is connected to them. Specifically, the first connecting block 211 and the second assembly block 212 can be fixed together using bolts. The mounting hole 215 includes a first mounting section 2151 and a second mounting section 2152. The first mounting section 2151 and the second mounting section 2152 are respectively opened on the first assembly block 211 and the second assembly block 212. The diameter of the end of the first mounting section 2151 closer to the second mounting section 2152 is larger than the diameter of the second mounting section 2152, and the diameter of the end of the first mounting section 2151 away from the second mounting section 2152 is smaller than the diameter of the end of the first mounting section 2151 closer to the second mounting section 2152. The sensing element 40 is disposed on the first mounting section 2151 and the second mounting section 2152 and extends out of the second assembly block 212 on the side away from the first assembly block 211. The moving component 30 is slidably covered on the second assembly block 212 along the first direction. The waterproof component 22 is connected to the end of the first mounting section 2151 away from the second mounting section 2152.

[0046] When it is necessary to disassemble or assemble the sensor 40, it is only necessary to remove the first connecting block 213 and the second connecting block 214 from the first assembly block 211 and the second assembly block 212, and separate the first assembly block 211 and the second assembly block 212 to quickly disassemble or assemble the sensor 40, thereby improving the convenience of disassembling and assembling the sensor 40. In addition, when the sensor 40 is installed in the mounting hole 215, the diameter of the end of the first mounting segment 2151 near the second mounting segment 2152 is larger than the diameter of the second mounting segment 2152, and the diameter of the end of the first mounting segment 2151 away from the second mounting segment 2152 is smaller than the diameter of the end of the first mounting segment 2151 near the second mounting segment 2152. This setting can restrict the movement of the sensor 40 in the first direction in the mounting hole 215, thereby improving the stability of the sensor 40 and the accuracy of the sensor 40 in sensing the movement distance of the moving component 30.

[0047] Please refer to further details. Figure 4In this embodiment, the moving component 30 includes a moving part 31 and an abutting part 32. The moving part 31 is slidably disposed on the fixed component 20 along a first direction. Specifically, the moving part 31 is slidably disposed on the second assembly block 212 of the fixed component 21 of the fixed component 20. The abutting part 32 is detachably disposed on the side of the moving part 31 away from the fixed component 20. The first detection surface 321 and the second detection surface 322 are both disposed on the abutting part 32. Since the first detection surface 321 and the second detection surface 322 will wear to a certain extent after repeated contact with the tool, thereby affecting the detection accuracy of the tool detection device 100, by setting the abutting part 32 to be detachably connected to the moving part 31 and setting the first detection surface 321 and the second detection surface 322 on the abutting part 32, it is convenient to quickly replace the abutting part 32.

[0048] In this embodiment, the abutment member 32 is plate-shaped and made of tungsten carbide. Tungsten carbide has properties such as wear resistance and high hardness. By making the abutment member 32 of tungsten carbide, the service life of the abutment member 32 can be improved. Understandably, the abutment member 32 can also be made of other wear-resistant and high-hardness materials.

[0049] In this embodiment, both the first detection surface 321 and the second detection surface 322 are polished to reduce the friction between them and the cutting tool, thereby reducing the risk of damaging the cutting tool.

[0050] In this embodiment, the movable component 31 has an inclined slot 311 on the side away from the fixed component 20, and the angle between the extending direction of the slot 311 and the first direction is an acute angle. The abutment component 32 is engaged in the slot 311. By setting the slot 311 to engage with the abutment component 32 and positioning the abutment component 32, the convenience and accuracy of installing the abutment component 32 are improved.

[0051] In this embodiment, the moving part 31 has a cleaning part 312, which is block-shaped and located on one side of the abutment part 32. The cleaning part 312 has a cleaning hole 3121, which is used to blow out air to clean the tool. Specifically, the cleaning part 312 can be located below the abutment part 32, and the cleaning hole 3121 is connected to an external air source (not shown) through an air pipe 50. Before inspecting the tool, the tool can be moved to a position directly opposite the cleaning hole 3121. The external air source introduces air into the cleaning hole 3121 through the air pipe 50, and the air blown out of the cleaning hole 3121 cleans the chips stuck on the tool. This effectively avoids the impact of chips on the tool on the accuracy of the tool inspection results and helps improve the processing quality of the product processed by the tool.

[0052] In some other embodiments, the cleaning unit 312 may also be separately disposed from the moving part 31, and this application embodiment does not specifically limit this.

[0053] In some other embodiments, a fan may be provided on the movable part 31 to blow away chips present on the tool, but this application does not specifically limit this embodiment.

[0054] Please see Figure 3 In this embodiment, the movable member 31 has a sliding annular groove 313 on the side facing the fixed component 20, and the second assembly block 212 of the fixed component 21 is slidably inserted into the sliding annular groove 313. This facilitates the sliding connection between the movable member 31 and the fixed component 21. In addition, when the movable member 31 moves relative to the fixed component 21, the sliding annular groove 313 cooperates with the fixed component 21 to support the movable member 31 along the circumference of the movable member 31, thereby improving the stability of the movable member 31's movement relative to the fixed component 21.

[0055] In this embodiment, the movable member 31 has an insertion hole 314 extending along the first direction on the side facing the fixed component 20. The insertion hole 314 is coaxially arranged with the sliding ring groove 313 and is located inside the sliding ring groove 313. The sensing element 40 extends into the insertion hole 314. The tool detection device 100 also includes a limiting member 60, which is inserted into the movable member 31 along the second direction and extends into the insertion hole 314 to abut against the sensing element 40. The limiting member 60 is used to restrict the movement of the sensing element 40 along the second direction. Since the sensing element 40 extends into the insertion hole 314 and has a certain gap with the hole wall of the insertion hole 314, when the moving member 31 moves relative to the fixed member 21, the sensing element 40 may shake in the second direction. By setting the limiting member 60 to abut against and restrict the movement of the sensing element 40 in the second direction, it is beneficial to improve the accuracy of the sensing element 40 in sensing the moving distance of the moving member 31, and thus to improve the accuracy of the tool detection device 100 in detecting the tool.

[0056] In this embodiment, there can be two limiting members 60. The two limiting members 60 are arranged opposite each other along the second direction, and the two limiting members 60 are respectively inserted into the moving member 31 from both sides and extend into the insertion hole 314 to abut against the sensing member 40. Since the two limiting members 60 abut against and limit the sensing member 40 from both sides, it is more stable, which further helps to improve the accuracy of the sensing member 40 in sensing the moving distance of the moving member 31.

[0057] In this embodiment, the end of the limiting member 60 that extends into the insertion hole 314 is arc-shaped, which can reduce the friction between the limiting member 60 and the sensing member 40, thereby effectively preventing the friction between the limiting member 60 and the sensing member 40 from being too large and affecting the movement of the moving member 31 relative to the fixed member 21.

[0058] In this embodiment, the movable member 31 has a threaded hole 315 communicating with the insertion hole 314 along the second direction, and the limiting member 60 is threadedly connected to the threaded hole 315, thereby facilitating the disassembly and assembly of the limiting member 60 and facilitating the adjustment of the limiting distance of the limiting member 60.

[0059] In this embodiment, the tool detection device 100 further includes an elastic element 70. Both ends of the elastic element 70 are connected to the fixing component 20 and the wall of the insertion hole 314, respectively. When the tool disengages from the first detection surface 321 or the second detection surface 322, the elastic element 70 drives the moving component 31 to return to its original position. Specifically, the elastic element 70 can be a spring. One end of the elastic element 70 is connected to the second assembly block 212 of the fixing component 21 of the fixing component 20, and the other end of the elastic element 70 is connected to the insertion hole 314. When the tool detection is completed and the spindle of the machining center drives the tool to disengage from the first detection surface 321 or the second detection surface 322, the elastic element 70 drives the moving component 31 to return to its original position, thereby facilitating the tool detection device 100 to detect the tool again.

[0060] In this embodiment, the insertion hole 314 includes a stop hole 3141 and a receiving hole 3142 that are sequentially connected and coaxially arranged. The stop hole 3141 is located on the side of the moving member 31 near the fixing component 20, and the receiving hole 3142 is located on the side of the stop hole 3141 away from the fixing component 20. The diameter of the stop hole 3141 is larger than the diameter of the receiving hole 3142. The sensing member 40 passes through the stop hole 3141 and extends into the receiving hole 3142. The threaded hole 315 communicates with the receiving hole 3142. The limiting member 60 extends along the second... The directional component is inserted into the movable component 31 and extends into the receiving hole 3142 to abut against the sensing component 40. The elastic component 70 is sleeved on the sensing component 40, and both ends of the elastic component 70 abut against the fixing component 20 and the end of the stop hole 3141 near the receiving hole 3142, respectively. This facilitates the installation of the elastic component 70. In addition, the end of the stop hole 3141 near the receiving hole 3142 abuts against the elastic component 70, which can limit the elastic component 70, thereby improving the accuracy of the elastic component 70 in driving the movable component 31 to move.

[0061] In some other embodiments, the diameter of the stop hole 3141 can be equal to the diameter of the receiving hole 3142, and the end of the elastic member 70 away from the fixing component 20 can also extend into the receiving hole 3142 and abut against the limiting member 60. This application embodiment does not specifically limit this.

[0062] In this embodiment, the receiving hole 3142 is conformally adapted to the end of the sensing element 40 away from the fixing element 21, which helps to improve the accuracy of the sensing element 40 in sensing the moving distance of the moving element 31.

[0063] In summary, the tool detection device 100 of this application embodiment slides the movable component 30 along the first direction onto the fixed component 20, and provides a first detection surface 321 and a second detection surface 322 on the movable component 30 for contacting the tool, and provides a sensing element 40 on the fixed component 20 that is directly opposite to the movable component 30. When it is necessary to detect the radial runout and tip shape of the cutting tool, it is only necessary to move the cutting tool toward the first detection surface 321 and the second detection surface 322 respectively, and make the peripheral wall of the cutting tool and the tip of the cutting tool abut against the first detection surface 321 and the second detection surface 322 respectively. The sensing element 40 can then sense the moving distance of the moving component 30, and thus accurately detect the radial runout and tip shape of the cutting tool based on the moving distance of the moving component 30. In this way, the cutting tool detection device 100 of this application realizes the function of automatically detecting the radial runout and tip shape of the cutting tool, improving the detection efficiency of cutting tool. In addition, since the cutting tool detection device 100 implemented in this application can accurately detect the radial runout and tip shape of the cutting tool, the accuracy of cutting tool detection is improved.
