[0002] During or after the use of cemented carbide end mill cutters, it is necessary to conduct quality inspection on the grinding condition of the cutting edges of the cutters to ensure the quality of the cutters and avoid the instability and insecurity of the cutter life during use.

[0003] In the prior art, the detection of the grinding condition of cemented carbide end mill cutters is usually carried out by means of image acquisition to detect whether there are sawteeth or scratches on the appearance of the cutters.

The cemented carbide end mill cutters with complex shapes can be called special-shaped cutters, that is, special-shaped cutters are used to process products with complex appearances. Due to the complexity of the cutting edges of special-shaped cutters, it is easier to have detection blind spots when fixing special-shaped cutters on conventional fixing devices, that is, there are areas that cannot be collected by the image acquisition device, thus affecting the detection results. It can be seen that the detection accuracy of special-shaped cutters in the prior art is relatively low. Content of the Utility Model

It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only parts related to the present utility model rather than all structures are shown in the drawings.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0045] The technical solution of the present utility model will be further described below in conjunction with the drawings and through specific embodiments.

[0046] This embodiment provides a cutting edge detection device for monitoring the grinding quality of carbide end mills or other special-shaped cutting tools, with more accurate detection results, higher flexibility and convenient operation.

[0047] As Figure 1 shown, the cutting edge detection device includes a cutting edge detection jig and an X-ray diffraction component 10. Among them, the cutting edge detection jig is used to position the tool 20 to be detected, and the X-ray diffraction component 10 is used to detect the tool 20 to be detected to obtain the stress value and deviation value on the cutting edge surface.

[0048] Among them, the X-ray diffraction component 10 includes an X-ray emitter 11 and an X-ray receiver 12. The X-ray emitter 11 is used to emit X-rays to the tool 20 to be detected, and the X-ray receiver 12 is used to receive the X-rays reflected by the tool 20 to be detected. According to the duration from when the X-ray emitter 11 emits X-rays to when the X-ray receiver 12 receives the X-rays, the stress value and deviation value on the cutting edge surface can be obtained. Among them, the method of detecting the stress value by X-rays is to measure the stress according to the change of the crystal plane spacing of the material or product, which is a non-destructive detection method. The specific principle can refer to the prior art and will not be elaborated in this embodiment.

[0049] The blade edge detection device provided in this embodiment can not only detect obvious appearance problems such as sawteeth and scratches on the surface of the cemented carbide end mill tool, but also detect the stress value and deviation value on the surface of the tool edge through the X-ray diffraction component 10 to characterize the grinding quality, so as to further improve the stability of the tool service life and the safety during use.

[0050] However, for special-shaped tools in the integral cemented carbide end mill, their structures are more compact and the contours are more complex, making it difficult to directly detect the stress and stress deviation of the overall special-shaped tool. The blade edge detection fixture in this embodiment can drive the tool 20 to be detected to rotate while positioning the tool 20 to be detected, and then adjust the orientation of the tool 20 to be detected, so as to move the area to be detected to the direction of the X-ray, avoiding detection blind spots.

[0051] The following is a detailed introduction to the blade edge detection fixture.

[0052] Specifically, as Figure 2 and Figure 3 shown, the blade edge detection fixture is characterized by including a base 100, a support member 200, and a locking component 300. Among them, the base 100 is used to be placed on a plane and can support the support member 200. The support member 200 is rotatably connected to the base 100, that is, the support member 200 can rotate relative to the base 100. The support member 200 rotates relative to the base 100 so that the support member 200 has multiple support positions (not shown in the figure) relative to the base 100, and the support member 200 can be switched between multiple support positions. The support member 200 is used to position the tool 20 to be detected, so that when the support member 200 rotates relative to the base 100, it can drive the tool 20 to be detected to rotate relative to the base 100.

[0053] In this embodiment, there can be various ways for the support member 200 to position the tool 20 to be detected. For example, the tool 20 to be detected can be positioned by means of support and limitation, or the tool 20 to be detected can also be positioned by means of clamping. This embodiment does not make any limitations in this regard.

[0054] As Figure 3As shown, the locking component 300 is disposed on the base 100 and can be selectively connected to the support member 200. When the locking component 300 is connected to the support member 200, the support member 200 can be locked in a support position. At this time, the support member 200 cannot rotate relative to the base 100. When the locking component 300 is not connected to the support member 200, the support member 200 is not locked and can rotate relative to the base 100. When the locking component 300 is connected to the support member 200 again, the support member 200 can be locked in another support position. It can be seen that the locking component 300 provided in this embodiment can lock the support member 200 in any support position, so that the support member 200 can be maintained in this support position, and further the tool 20 to be detected can be maintained in a position, facilitating the detection of the tool 20 to be detected.

[0055] In the edge detection jig provided in this embodiment, the support member 200 for supporting the tool 20 to be detected is rotatably connected to the base 100, and the support member 200 has a plurality of support positions by rotating relative to the base 100. The locking component 300 is disposed on the base 100 and can be selectively connected to the support member 200 to lock the support member 200 in a support position, so that the support position of the support member 200 can be adjusted according to the specific abnormal shape of the tool 20 to be detected, and further the purpose of adjusting the orientation of the tool 20 to be detected is achieved, so that the position to be detected of the tool 20 to be detected can face the direction from which the X-ray is emitted, and other abnormal structures will not block the X-ray receiver 12 from receiving the rays reflected by the tool 20 to be detected, reducing the difficulty of edge detection, avoiding the situation of detection blind spots, improving the accuracy of the detection result, and thus being able to assist the X-ray diffraction component 10 in detecting the stress value and deviation value on the surface of the tool edge to characterize the grinding quality, so as to further improve the stability of the tool service life and the safety during use.

[0056] In some alternative embodiments, the base 100 can be an integral structure. Of course, it can be understood that, as Figure 2 、 Figure 3 and Figure 7 shown, the base 100 can be a split structure.

[0057] For example, the base 100 includes a base body 130 and a connecting block 140 disposed on the base body 130, and the support member 200 can be rotatably connected to the connecting block 140. The value range of the length L1 of the base body 130 is 40 mm to 48 mm. For example, the length L1 of the base body 130 is 40 mm, 45 mm, 48 mm, etc. The value range of the width W1 of the base body 130 is 35 mm to 45 mm. For example, the width W1 of the base body 130 is 35 mm, 40 mm, 15 mm, etc. The value range of the height H2 of the base body 130 is 3 mm to 6 mm. For example, the height H2 of the base body 130 is 3 mm, 5 mm, 6 mm, etc. As Figure 1 shown, the value range of the overall height H1 of the cutting edge detection jig is 28 mm to 32 mm. For example, the overall height H1 of the cutting edge detection jig is 18 mm, 30 mm, 32 mm, etc. In this embodiment, when the support member 200 rotates relative to the base 100, the overall height of the cutting edge detection jig will increase by 0 to 3 mm on the original basis.

[0058] Exemplarily, the support member 200 is universally rotatably connected to the base 100, making the movement of the support member 200 relative to the base 100 more flexible and having more support positions. Furthermore, the tool 20 to be detected can have more orientations, further ensuring that there will be no detection blind spots. Among them, the universal rotatable connection means that the support member 200 can have multiple virtual rotation axes in space to rotate relative to the base 100 at different angles. For example, the virtual rotation axis can extend along the length direction of the base 100, can also extend along the width direction of the base 100, can also extend along the height direction of the base 100, and can also extend along any direction between the length direction and the width direction, between the width direction and the height direction, and between the length direction and the height direction. This embodiment does not limit this. The drawings in this embodiment show the situation where the virtual rotation axis of the support member 200 extends along the width direction of the base 100.

[0059] There can be various ways for the support member 200 to be rotatably connected to the base 100. Exemplarily, as Figure 2 and Figure 3 shown, the base 100 is provided with a positioning groove 110. The bottom of the support member 200 cooperates with the positioning groove 110, and the bottom of the support member 200 is rotatably placed in the positioning groove 110. By providing the positioning groove 110, the limit of the bottom of the support member 200 can be realized, reducing the probability of the support member 200 separating from the base 100 during the rotation process, and having high reliability. In this embodiment, the positioning groove 110 is opened on the surface of the connecting block 140 facing away from the base body 130, that is, the positioning groove 110 is opened on the top surface of the connecting block 140.

[0060] Further optionally, as Figure 2As shown, the base 100 is provided with a threaded hole 120 that extends from the outer surface of the base 100 to the positioning groove 110 to communicate with the positioning groove 110. As Figure 3 As shown, the locking assembly 300 includes a locking member having an external thread (not shown in the figure). The locking member has a locked state and an unlocked state. When the locking member is in the locked state, the locking member is screwed into the threaded hole 120 and abuts against the support member 200 in the positioning groove 110 to prevent the support member 200 from rotating relative to the base 100, thereby achieving the locking of the support member 200. When the locking member is in the unlocked state, the locking member is separated from the support member 200 to no longer restrict the movement of the support member 200. In this embodiment, the structure of the locking assembly 300 for the support member 200 is relatively simple, enabling the structure of the cutting edge detection jig to be relatively simple, reducing the cost of the cutting edge detection jig, and moreover, combining the advantages of screwing, resulting in higher reliability and longer service life during the locking and unlocking processes.

[0061] Optionally, the locking member can axially move relative to the base 100 under an external force to switch between the locked state and the unlocked state. Exemplarily, the axial movement of the locking member relative to the base 100 can be achieved by screwing the locking member.

[0062] Exemplarily, the locking member can be a bolt or a screw, and this embodiment does not limit this. Exemplarily, the aperture range of the threaded hole 120 is 4 mm to 8 mm. For example, the aperture of the threaded hole 120 is 4 mm, 6 mm, 8 mm, etc.

[0063] To improve the locking effect on the support member 200, multiple locking members and threaded holes 120 can be provided in a one-to-one correspondence, and this embodiment does not limit this.

[0064] In some alternative embodiments, as Figure 3 and Figure 4 shown, the bottom of the support member 200 and the positioning groove 110 are both semi-cylindrical to facilitate the rotation of the support member 200 in the positioning groove 110 and reduce the rotation resistance. It should be noted that the axial direction of the positioning groove 110 is the same as the axial direction of the semi-cylindrical part of the support member 200. In this embodiment, the extending direction of the virtual rotation axis when the support member 200 rotates is the same as the axial direction of the positioning groove 110.

[0065] Exemplarily, the radius of the positioning groove 110 is the same as the radius of the bottom of the support member 200, and the thickness range of the positioning groove 110 is 3 mm to 8 mm. For example, the thickness of the positioning groove 110 is 3 mm, 6 mm, 7 mm, 8 mm, etc.

[0066] Of course, it can be understood that the bottom of the positioning groove 110 and the support member 200 can also be in other shapes, such as semi-conical or hemispherical, and this embodiment does not limit this.

[0067] Optionally, as Figure 2 shown, the support member 200 is rotatably connected to the base 100 about a virtual rotation axis extending along the first direction X. The angle between the axis of the support member 200 in the second direction Y and the axis of the base 100 in the second direction Y is -45° to 45°. That is, the rotation range of the support member 200 relative to the base 100 is -45° to 45°, so as to be able to meet the blind - area - free detection of most of the to - be - detected tools 20, and it has high practicability and application range. It should be noted that Figure 2 is a schematic diagram when the angle between the axis of the support member 200 in the second direction Y and the axis of the base 100 in the second direction Y is 0; the amplitude of the angle between the axis of the support member 200 in the second direction Y and the axis of the base 100 in the second direction Y means that the bottom of the support member 200 rotates towards one side of the base 100, and the positive value of the angle between the axis of the support member 200 in the second direction Y and the axis of the base 100 in the second direction Y means that the bottom of the support member 200 rotates towards the other side of the base 100.

[0068] Among them, as Figure 2 shown, the second direction Y is perpendicular to the first direction X.

[0069] Optionally, as Figure 4 and Figure 5 shown, the top of the support member 200 includes a top plane 210 and an inclined plane 220 which are arranged at an angle and butt - jointed. Specifically, one end of the inclined plane 220 departing from the top plane 210 inclines towards the bottom of the support member 200. That is, the inclined plane 220 is inclined obliquely downwards. By setting the inclined plane 220, the tool tip of the to - be - detected tool 20 can be avoided, so as to facilitate detection. Optionally, as Figure 6 shown, the value range of the angle a between the top plane 210 and the inclined plane 220 is 120° to 140°. For example, the angle a between the top plane 210 and the inclined plane 220 is 120°, 135°, 140°, etc.

[0070] Among them, the top plane 210 is provided with a first groove 211, and the inclined plane 220 is provided with a second groove 221 communicated with the first groove 211. Both the first groove 211 and the second groove 221 are used for positioning the to - be - detected tool 20. By setting the first groove 211 and the second groove 221, it can facilitate meeting the shape requirements of the to - be - detected tool 20, better position the to - be - detected tool 20, improve the positioning efficiency, and the first groove 211 and the second groove 221 can also position different areas of the to - be - detected tool 20.

[0071] In some alternative embodiments, as Figure 5As shown, both the first groove 211 and the second groove 221 are right-angled triangular grooves, so that the first groove 211 and the second groove 221 have a relatively large accommodating space to be able to position the tool 20 to be detected with different radial dimensions, improving versatility. Moreover, by clamping the tool 20 to be detected through the V-shaped groove walls, the stability and convenience of fixing the tool to be detected can be improved. Further, both the first groove 211 and the second groove 221 are isosceles right-angled triangular grooves.

[0072] In this embodiment, the depth b of the first groove 211 is equal to the depth of the second groove 221, so that the first groove 211 and the second groove 221 can better transition, improving the positioning effect on the tool 20 to be detected, and also facilitating the machining and manufacturing of the first groove 211 and the second groove 221.

[0073] Exemplarily, the value range of the depth b of the first groove 211 is 5 mm to 10 mm. For example, the depth b of the first groove 211 is 5 mm, 8 mm, 10 mm, etc.

[0074] In this embodiment, as Figures 4 to 6 shown, the support member 200 further includes an arc surface 230, a first plane 240, a second plane 250, a third plane 260, and a fourth plane 270. Among them, the first plane 240 and the second plane 250 are opposite and parallel to each other and are both tangent to the arc surface 230. The third plane 260 and the fourth plane 270 are opposite and parallel to each other. The third plane 260 is connected to one end of the arc surface 230, one end of the first plane 240, one end of the second plane 250, one end of the top plane 210, and one end of the inclined surface 220. The fourth plane 270 is connected to the other end of the arc surface 230, the other end of the first plane 240, the other end of the second plane 250, the other end of the top plane 200, and the other end of the inclined surface 220, so that the top plane 200, the inclined surface 220, the arc surface 230, the first plane 240, the second plane 250, the third plane 260, and the fourth plane 270 cooperate to form a closed three-dimensional structure. In this embodiment, the top plane 210 is perpendicular to the second plane 250, the third plane 260, and the fourth plane 270, and the second plane 250 is perpendicular to the third plane 260 and the fourth plane 270.

[0075] The material of the support member 200 in this embodiment includes but is not limited to plastics, acrylics, stainless steels, etc. The material of the base 100 includes but is not limited to materials that are not easily rusted and deformed, such as aluminum alloy, stainless steel, and copper.

[0076] The edge detection device provided in this embodiment is used to detect the tool 20 to be detected. The material of the tool tip of the tool 20 to be detected can be polycrystal. Taking the carbide special-shaped tool as the tool 20 to be detected and being a special-shaped tool as an example, by using the X-ray diffraction component 10 to measure the stress value and deviation value of the edge of the carbide special-shaped tool, the processing quality of the edge of the special-shaped tool is detected, filling the blank of the edge detection of the special-shaped tool. And, since the contour of the special-shaped tool is complex, in order to meet the edge detection of various special-shaped tools, an edge detection jig with an adjustable angle is designed to meet the detection requirements.

[0077] Figure 8 and Figure 9 show two groups of detection result diagrams when detecting the edge of the special-shaped tool. The specific detection method is sin 2 Ψ method, also known as X-ray diffraction method. Among them, Figure 8 and Figure 9 the abscissa in both is sin 2 Ψ, where Ψ takes 180°. The ordinate in both is the lattice constant. The unit is The difference is that Figure 8 the normal stress of the special-shaped tool in is -314.9 ± 49.7 MPa, Figure 9 the normal stress of the special-shaped tool in is -285.6 ± 73.1 MPa.

[0078] Obviously, the above embodiments of the present invention are only for clearly illustrating the examples made by the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
