DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] See also Figures 1 to 4 The utility model provides a machine tool tool wear monitoring device, comprising: a detection mechanism, a clamping mechanism and a cleaning mechanism.

[0030] The detection mechanism includes a visual detection module 1 and a connecting plate 2. The connecting plate 2 is L-shaped and is provided with a horizontal plate and a left end (with Figure 1 The visual inspection module 1 is fixed to the bottom of the horizontal plate of the connecting plate 2 and is located at the angle between the horizontal plate and the vertical plate.

[0031] In this embodiment, the visual inspection module 1 may be an industrial camera, with its lens facing horizontally to the right.

[0032] Furthermore, the clamping mechanism includes a fixed plate 3, a first clamping plate 4 and an adjustable fastener, the fixed plate 3 is fixedly connected to the connecting plate 2, the first clamping plate 4 is slidably installed on the fixed plate 3, the adjustable fastener is connected to the fixed plate 3 and the first clamping plate 4, and the adjustable fastener is used to fix the fixed plate 3 and the first clamping plate 4 on the external tool driving frame, so that when the tool driving frame drives the tool to move, it can drive the visual inspection module 1 to move synchronously, ensuring that the lens of the visual inspection module 1 can always face the tool, so that subsequent staff do not need to frequently manually adjust the position when using the visual inspection module 1 to monitor the tool in real time, thereby reducing labor input and improving the practicality of the machine tool tool wear monitoring device.

[0033] See also Figure 2 The fixing plate 3 is also L-shaped, and is provided with a side plate 301 distributed in the vertical direction and a second clamping plate 302 distributed parallel to the first clamping plate 4. A first slide groove 3011 is provided on the side plate 301 in the horizontal direction, and a first slider 401 is provided on the first clamping plate 4. The first slider 401 is slidably fitted in the first slide groove 3011.

[0034] In this embodiment, the adjustable fastener includes a screw 7 and a nut 18. The screw 7 is arranged in parallel with the first slide slot 3011. One end of the screw 7 is fixedly connected to the second clamping plate 302, and the other end of the screw 7 passes through the first clamping plate 4 and is connected to the nut 18. During clamping, the first clamping plate 4 and the second clamping plate 302 are arranged on both sides of the tool drive frame, and the first clamping plate 4 is pushed to move toward the second clamping plate 302 by rotating the nut 18 until the first clamping plate 4 and the second clamping plate 302 are fixedly clamped on the tool drive frame, so that the subsequent tool drive frame drives the visual inspection module 1 to move synchronously in the process of driving the tool to move.

[0035] Furthermore, anti-slip soft rubber pads 12 are installed on the sides of the first clamping plate 4 and the second clamping plate 302 facing each other. The material of the anti-slip soft rubber pads 12 can be selected from rubber, silicone, soft rubber plastic, etc., which can increase the friction between the first clamping plate 4, the second clamping plate 302 and the tool drive frame to ensure the reliability of clamping.

[0036] In addition, the outer side surfaces of the first clamping plate 4 and the second clamping plate 302 (ie, the sides of the first clamping plate 4 and the second clamping plate 302 facing away from each other) are both installed with positioning clamping blocks 8, and the two positioning clamping blocks 8 are used to further clamp the external tool drive frame.

[0037] Among them, the two positioning clamping blocks 8 are both L-shaped and symmetrically distributed, and the tops of the two positioning clamping blocks 8 are provided with clamping parts 801 bent toward each other, and suction cups 9 are installed on the sides of the two clamping parts 801 facing each other. The two suction cups 9 are used to perform secondary clamping and fixing of the tool drive frame, so as to prevent the clamping mechanism from falling off from the tool drive frame during use.

[0038] During the installation process of the clamping mechanism, in order to avoid the suction cup 9 being adsorbed on the outer surface of the tool drive frame before it is installed in place, causing inconvenience in subsequent position adjustment and resulting in a long installation time, the utility model adopts the method of rotating the two positioning clamping blocks 8 in the outer side grooves of the first clamping plate 4 and the second clamping plate 302 respectively through pin shafts, and limiting mechanisms are provided between the first clamping plate 4 and the positioning clamping block 8 thereon, and between the second clamping plate 302 and the positioning clamping block 8 thereon, and the respective positioning clamping blocks 8 are limited by the limiting mechanisms.

[0039] For details, see Figure 3 The limiting mechanisms include a limiting rod 10 and a U-shaped limiting block 11. The outer surfaces of the two positioning clamping blocks 8 are provided with positioning slots 802, and the limiting rod 10 is slidably connected to the positioning slots 802.

[0040] When clamping, the two positioning clamping blocks 8 can be rotated outward first to make them in an inverted eight-shaped distribution, and then the adjustable fasteners can be operated to fix the first clamping plate 4 and the second clamping plate 302 on the tool drive frame; then, the two positioning clamping blocks 8 are pushed to drive the suction cup 9 to rotate to a position that is roughly in the same vertical plane as the corresponding non-slip soft rubber pad 12, so that the two suction cups 9 are respectively adsorbed on both sides of the tool drive frame to form a secondary clamping fixation; finally, the two limit rods 10 are pushed respectively, and one end of each of the two limit rods 10 is respectively inserted into the grooves of the two U-shaped limit blocks 11 (such as Figure 3 As shown), to limit the rotation of the positioning clamping block 8.

[0041] See also Figure 4The cleaning mechanism includes a transparent plate 5, a cleaning scraper 6 and a cleaning drive device. The transparent plate 5 is mounted on the connecting plate 2 and is located in front of the lens of the visual inspection module 1. The cleaning scraper 6 is connected to the cleaning drive device and is parallel to the transparent plate 5. The cleaning drive device is used to drive the cleaning scraper 6 to move toward the transparent plate 5 to scrape off the debris attached to the outer surface of the transparent plate 5. The utility model arranges a transparent plate 5 in front of the visual inspection module 1, and uses the transparent plate 5 to block the debris generated when the tool processes the workpiece, so as to prevent the debris from being attached to the visual inspection module 1. The debris attached to the transparent plate 5 is scraped off by the cleaning drive device driving the cleaning scraper 6, so as to prevent the debris from blocking the monitoring line of sight of the visual inspection module 1, and ensure the reliability and accuracy of the monitoring of the visual inspection module 1.

[0042] In this embodiment, the right end of the horizontal plate of the connecting plate 2 is fixedly connected to the side plate 301 of the fixed plate 3, and the bottom of the vertical plate of the connecting plate 2 is fixed with a bottom plate 13, and a quality detection module 14 is installed on the bottom plate 13.

A limit hole 201 is provided on the horizontal plate of the connecting plate 2, and the transparent plate 5 is inserted into the limit hole 201 along the vertical direction, and the transparent plate 5 is supported on the quality detection module 14. Since the quality of the transparent plate 5 in the utility model is completely borne by the quality detection module 14, when the transparent plate 5 is attached to the sundries, its mass increases. Once the quality detection module 14 detects that the quality of the transparent plate 5 exceeds the preset threshold, the controller of the tool wear monitoring device of the machine tool of the utility model receives the detection signal and controls the cleaning drive device to drive the cleaning scraper 6 to move toward the transparent plate 5 to scrape off the sundries attached to the outer surface of the transparent plate 5.

[0043] In this embodiment, the cleaning mechanism further includes a mounting bracket 15 and a mounting plate 16. The mounting bracket 15 is also L-shaped and is provided with a crossbar and a vertical bar. One end of the crossbar is fixedly connected to the bottom plate 13, and the lower end of the vertical bar is fixedly connected to the other end of the crossbar. A second slide groove 1501 is provided on the crossbar of the mounting bracket 15, and a second slider 1601 is provided at the bottom of the mounting plate 16. The second slider 1601 is slidably fitted in the second slide groove 1501.

[0044] Exemplarily, the cleaning drive device may adopt an electric telescopic rod 17 , which is mounted on the vertical rod portion of the mounting bracket 15 and connected to the mounting plate 16 . The cleaning scraper 6 is mounted on the mounting plate 16 and is located outside the transparent plate 5 .

[0045] Exemplarily, the transparent plate 5 may be made of acrylic material, and a protective film may be provided on its outer surface, the protective film serves to prevent the transparent plate 5 from being scratched by the cleaning blade 6 .

[0046] It can be seen that the utility model of the machine tool tool wear monitoring device fixes the fixed plate 3 and the first clamping plate 4 on the external tool drive frame by operating the adjustable fasteners of the clamping mechanism, so that when the tool drive frame drives the tool to move, it can drive the visual inspection module 1 to move synchronously, ensuring that the lens of the visual inspection module 1 can always face the tool, so that the subsequent staff does not need to frequently manually adjust the position when using the visual inspection module 1 to monitor the tool in real time, thereby reducing labor input and improving the practicality of the machine tool tool wear monitoring device; at the same time, positioning clamping blocks 8 are installed on the outer sides of the first clamping plate 4 and the second clamping plate 302, and the suction cups 9 on the two positioning clamping blocks 8 are used to clamp and fix the tool drive frame for the second time, so as to prevent the clamping mechanism from falling off from the tool drive frame during use. In addition, the utility model sets a transparent plate 5 in front of the visual inspection module 1, and uses the transparent plate 5 to block the debris generated when the tool processes the workpiece, so as to prevent the debris from adhering to the visual inspection module 1. The debris attached to the transparent plate 5 is scraped off by the cleaning scraper 6 driven by the cleaning drive device, so as to prevent the debris from blocking the monitoring line of sight of the visual inspection module 1, thereby ensuring the reliability and accuracy of the monitoring of the visual inspection module 1; and the quality inspection module 14 is used to detect the quality change of the transparent plate 5, so as to control the cleaning drive device to drive the cleaning scraper 6 to remove the debris on the transparent plate 5 in time.
