Description

Technical Field

[0001] This invention relates to the field of tool wear detection technology, and more particularly to an online imaging device for tool side edge. Background Technology

[0002] The parameters and quality of cutting tools directly determine the quality and pass rate of machining. To ensure the machining quality of CNC machine tools in automated machining processes, it is necessary to take images of the side cutting edges of the cutting tools during use. Wear detection of the cutting tools is then performed based on these images to ensure the machining quality of parts, improve production efficiency, and reduce production costs.

[0003] However, currently, when taking images of the side edge of a cutting tool, the tool needs to be removed and moved to the shooting position for shooting. It is impossible to shoot and inspect the tool on-machine, let alone shoot the side edge of the cutting tool from different angles on-machine, which reduces production efficiency.

[0004] Therefore, existing technologies still need improvement and development. Summary of the Invention

[0005] The main objective of this invention is to provide an online image capture device for the side edge of cutting tools, which aims to solve the problem that existing technologies cannot capture images of the side edge of cutting tools on-site, thus reducing production efficiency.

[0006] To achieve the above objectives, the present invention provides an online imaging device for the side edge of a cutting tool, wherein the imaging device comprises:

[0010] A slider is mounted on the guide rail. The slider is provided with a fixing component for fixing the shooting equipment. The slider can slide along the guide rail to adjust the distance between the shooting equipment and the blade.

[0011] An angle indicating component, fixed on the rotating component, is used to indicate the angle between the imaging device and the cutting tool on the indexing plate.

[0012] Optionally, the indexing plate is a magnetic indexing plate, used to be attached to the machine tool.

[0013] Optionally, an observation window is provided at one end of the angle indicating component away from the rotating component, for reading the angle corresponding to the scale line of the scale at the position of the observation window.

[0014] Optionally, the angle indicating member has a first slot extending radially along the indexing plate and a second slot extending circumferentially along the indexing plate at one end away from the rotating member, the first slot and the second slot forming the observation window.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0035] Analyzing images of the tool's side cutting edge allows for the detection of tool wear and breakage, and the determination of the VB (flank wear) value. Therefore, capturing images of the tool's side cutting edge is crucial for monitoring tool wear and breakage. However, currently, capturing these images requires stopping the machine and removing the tool, which is inconvenient and reduces production efficiency.

[0036] This invention provides an online image capture device for the side edge of a cutting tool, which can be magnetically mounted on a machine tool. The angle and distance between the image capture device and the cutting tool can be adjusted, and the side edge image of the cutting tool can be captured without disassembling the tool, realizing on-machine shooting and improving production efficiency.

[0037] The following describes the online imaging device for the side cutting edge of a CNC machine tool in detail, using online imaging as an example. In this embodiment, the imaging device is a box-shaped microscope, and the online imaging device for the side cutting edge is as follows: Figure 1 and Figure 2As shown, it mainly includes: a scale plate 10, a rotating component 20, a guide rail 30, a slider 40, and an angle indicating component 50. The rotating component 20 drives the guide rail 30, slider 40, and angle indicating component 50 to rotate. The scale plate 10 is disc-shaped and has graduation lines 11 along its circumference. The angle indicating component 50 is used to position the graduation lines 11 and read the angle between the microscope and the cutting tool. The slider 40 is moved on the guide rail 30 to adjust the distance between the microscope and the cutting tool, allowing for on-the-fly imaging of the cutting tool's side edge without removing the cutting tool.

[0038] The indexing dial 10 in this embodiment has a precise angle fine-tuning function, which can be adjusted to an accuracy of 1° each time. When photographing the side edge of the tool at different times, the angle of the microscope can be precisely adjusted according to the angle recorded at the last time the photograph was taken, ensuring that the angle remains unchanged for each photograph and improving the stability of the photographing angle.

[0039] To facilitate installation and online shooting, the indexing plate 10 in this embodiment is a magnetic indexing plate, capable of magnetically adhering to the CNC machine tool. However, it is not limited to this method of adhering; a suction cup can also be installed at the bottom of the indexing plate 10, using the suction force of the suction cup to fix the shooting device to the CNC machine tool. No additional mounting components are required, resulting in a simple structure; it can be installed in multiple positions on the CNC machine tool, facilitating installation and removal without affecting the working space of the CNC machine tool.

[0040] The guide rail 30 is long and narrow, with a groove 31 at its top. The microscope is mounted on the slider 40. By sliding the slider 40 back and forth along the groove 31 on the guide rail 30, the relative distance between the microscope and the cutting tool can be precisely adjusted, ensuring that the image of the side edge of the cutting tool is clearly captured.

[0041] In one embodiment, scales for marking distances are provided on both sides of the slide groove 31 to facilitate recording and saving the relative distance between the microscope and the cutting tool, so as to quickly adjust the distance between the microscope and the cutting tool at different times.

[0042] The guide rail 30 is fixed to the top of the rotating component 20. The rotating component 20 is coaxially mounted on the indexing plate 10. The rotating component 20 is equipped with a bearing 21. When the bearing 21 rotates, it drives the guide rail 30 to rotate, which in turn drives the slider 40 and the microscope to rotate.

[0043] Because the guide rail 30 is relatively long, the farther the slider 40 is from the rotating component 20, the greater the lateral force exerted by the slider 40 and the weight of the microscope on the rotating component 20. Therefore, the bearing 21 of the rotating component 20 experiences uneven stress, resulting in unstable rotation and a tendency to vibrate. Therefore, in this embodiment, the rotating component 20 is equipped with two superimposed bearings 21 for support, which, through internal friction and rolling mechanical action, drive the guide rail 30, slider 40, and angle indicating component 50 to rotate.

[0044] like Figure 3 As shown, the bottom of the slider 40 is a sliding strip 43 that mates with the sliding groove 31, and the top is a square frame 41, forming a fixing component for mounting the microscope. The size of the square frame 41 is designed according to the size of the microscope. The shape of the fixing component can also vary according to the shape of the microscope. An elastic pressing strip 42 is provided on the inner side of the square frame 41. When the microscope is pressed into the square frame 41, the elastic pressing strip 42 is squeezed, so that the microscope is fixed in the square frame 41 with an interference fit. It should be noted that the method of mounting the microscope on the slider 40 is not limited, and other conventional fixing structures can also be used. For example, the size of the movable buckle can be adjusted by electronic equipment to install and fix the microscope, enhancing the stability and safety of the microscope fixing device.

[0045] The angle indicating component 50 is stepped and includes a first component 52, a second component 53, and a third component 54. The first component 52 is located at the top of the angle indicating component 50, and a threaded hole 56 is provided on the side of the first component 52. The angle indicating component 50 is fixed to the side of the rotating component 20 through the threaded hole 56. The second component 53 is located in the middle of the angle indicating component 50. In order to keep the angle of the online imaging device constant when capturing images of the cutting tool, a first locking hole 55 is provided on the second component 53, and a positioning plate 60 is coaxially mounted on the indexing plate 10. Multiple second locking holes 61 are provided around the circumference of the positioning plate 60. By passing a rod-shaped object through the first locking hole 55 and then inserting it into the second locking hole 61, the angle between the microscope and the cutting tool can be limited, preventing the guide rail 30 or the angle indicating component 50 from being accidentally touched and rotating, thus changing the angle between the microscope and the cutting tool.

[0046] The third component 54 is located at the bottom of the angle indicating component 50. The third component 54 has an observation window 51, which is used to read the angle corresponding to the scale line on the scale plate 10 at the position of the observation window 51. The microscope's rotation angle can be adjusted based on the observed scale value. Specifically, the angle indicating component 50 has a first slot 51a and a second slot 51b at the end away from the rotating component 20. The first slot 51a extends radially along the scale plate 10, and the second slot 51b extends circumferentially along the scale plate 10. The first slot 51a and the second slot 51b are connected to form the observation window 51. Therefore, the online imaging device can flexibly adjust the imaging angle, ensuring that the imaging position of the side edge of the same tool is accurate and consistent each time it is photographed, thereby improving data consistency and accuracy. In one example, a pointer is provided at the end of the third component 54 to indicate the angle corresponding to the scale line on the scale plate 10. For example, if the extension direction of the guide rail on the CNC machine tool is constant and taken as the 0° direction of the indexing plate 10, when taking pictures at different positions, first adjust the 0° direction of the indexing plate 10 to be the same as the extension direction of the guide rail, and then adjust the shooting angle. The specific shooting angle value can be read through the observation window 51.

[0047] As described above, the online imaging device of this embodiment is magnetically fixed to a CNC machine tool and can rotate. Even if the side-edge angles of each tool are different or the imaging positions are different, it can still capture the side-edges of the tools well, making it widely applicable. It solves the problems of different side-edge angles for each tool and inconsistent imaging positions each time, and is also lightweight, simple in structure, and low in cost. Compared with traditional fixing devices, it can capture the side-edges of tools with different numbers of cutting edges.

[0048] In one embodiment, an electronic control device can be added to the rotating component to precisely control and adjust the rotating component, thereby better ensuring the accuracy and consistency of the shooting angle.

[0049] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not mean that the essence of the corresponding technical solutions deviates from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
