[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0034] Furthermore, two groups of monitoring mechanisms and cleaning mechanisms can be symmetrically installed on the outer side of the mounting plate 1, so that detection and cleaning can be performed when the cutter disc 3 drives the cutter body 6 to rotate forward and reversely.

[0035] In this embodiment, the limiting mechanism includes a support column 9 fixedly mounted on the outer surface of the mounting plate 1 close to the support tube 2. The support column 9 is inserted into the interior of the mounting tube 5, and a limiting disk 10 is fixedly mounted on the end of the support column 9 away from the mounting plate 1. A square limiting block 7 is fixedly mounted on the outer surface of the mounting tube 5, and one side of the square limiting block 7 is in contact with the outer surface of the limiting disk 10. When in use, the square limiting block 7 is in contact with the surface of the limiting disk 10, so that the mounting tube 5 cannot rotate, thereby achieving a limiting effect on the tool body 6 installed in the mounting tube 5; a rotating component is installed between the mounting tube 5 and the limiting disk 10.

[0036] In this embodiment, the monitoring mechanism includes two rollers 17 rotatably mounted on the outer surface of the mounting plate 1 close to the cutter disc 3, the outer surfaces of the two rollers 17 are sleeved with a transmission belt 18, and two industrial cameras 19 are fixedly mounted equidistantly on the side of the transmission belt 18 away from the mounting plate 1, and the outer surface of the mounting plate 1 located between the two rollers 17 is fixedly mounted with two arc guide plates 20, and the two arc guide plates 20 are respectively in contact with the inner and outer sides of the transmission belt 18, and the movement path of the industrial camera 19 is guided by the two arc guide plates 20, so that the industrial camera 19 can move synchronously with the cutting edge of the tool body 6; a protective cover 27 for protecting the detection mechanism is fixedly mounted on the outer surface of the mounting plate 1, and an opening is opened on the outer surface of the protective cover 27 for exposing a single industrial camera 19, and the transmission assembly includes two pulleys 21 respectively fixedly mounted on the output end of the stepper motor 16 and the rotation center of the roller 17, and the outer surfaces of the two pulleys 21 are sleeved with belts 22.

[0037] When the output end of the stepper motor 16 rotates, the roller 17 will be driven to rotate through the pulley 21 and the belt 22, so that the transmission belt 18 sleeved on the outer surface of the roller 17 can drive the industrial camera 19 to move synchronously with the movement of the tool body 6, so as to ensure the clarity and accuracy of the industrial camera 19 shooting the cutting edge of the tool body 6.

[0039] When the cutter disc 3 drives the used tool body 6 to rotate to the arc-shaped opening 11 through the mounting seat 4 and the mounting tube 5, the side of the square limit block 7 installed on the mounting tube 5 no longer contacts the limit plate 10, and at the same time, the transmission gear 8 will also engage with the teeth of the incomplete end face gear ring 12, so that when the cutter disc 3 rotates, the transmission gear 8 can drive the mounting tube 5 and the tool body 6 to rotate 360 ​​degrees, so that the industrial camera 19 installed on the mounting plate 1 can comprehensively shoot and detect the cutting edge of the tool body 6.

[0040] In this embodiment, a cleaning mechanism is installed on the outer surface of the mounting plate 1 close to the monitoring mechanism, and the cleaning mechanism includes a nozzle pipe group 23 fixedly installed on the outer surface of the mounting plate 1, and an air pump 24 is fixedly installed on the outer surface of the mounting plate 1. The air outlet end of the air pump 24 is connected to the interior of the nozzle pipe group 23. A conductive component is installed between the cutter disc 3 and the mounting plate 1. The conductive component includes a conductive column 25 fixedly installed on the outer periphery of the cutter disc 3 close to each mounting seat 4. A conductive sheet 26 is fixedly installed on the outer surface of the mounting plate 1 close to the nozzle pipe group 23, and the conductive column 25 is intermittently attached to the conductive sheet 26.

[0041] After the conductive column 25 installed on the tool disc 3 contacts the conductive sheet 26, the power of the air pump 24 is connected to make the air pump 24 blow air into the nozzle pipe group 23, so that the nozzle pipe group 23 blows out gas to clean the impurities adhered to the tool body 6, so as to prevent the impurities from blocking the cutting edge of the tool body 6 and affecting the shooting and detection effect of the industrial camera 19.

[0042] A method for using a tool switching device for a numerically controlled machine tool comprises the following steps:

[0043] S1: The stepping motor 16 drives the driving gear 14 to rotate, so that the driving gear 14 drives the cutter disc 3 to rotate in the direction of the monitoring mechanism through the driven gear 13 and the support tube 2 meshing therewith, thereby realizing the switching of the tool body 6;

[0045] S3: When the cutter disc 3 drives the used tool body 6 to rotate to the arc-shaped opening 11 through the mounting seat 4 and the mounting tube 5, the side of the square limit block 7 installed on the mounting tube 5 no longer contacts the limit plate 10, and at the same time, the transmission gear 8 will also engage with the teeth of the incomplete end face gear ring 12, so that when the cutter disc 3 rotates, the transmission gear 8 can drive the mounting tube 5 and the tool body 6 to rotate 360 ​​degrees, so that the industrial camera 19 installed on the mounting plate 1 can comprehensively shoot and detect the cutting edge of the tool body 6.

[0046] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when the tool body 6 needs to be switched, the driving gear 14 is driven to rotate by the stepping motor 16, so that the driving gear 14 drives the cutter disc 3 to rotate in the direction of the monitoring mechanism through the driven gear 13 and the support tube 2 meshing therewith, and when the cutter disc 3 drives the used tool body 6 to rotate to the arc-shaped opening 11 through the mounting seat 4 and the mounting tube 5, the side of the square limit block 7 installed on the mounting tube 5 is no longer in contact with the limit plate 10, and at the same time, the transmission gear 8 will also be meshed with the teeth of the incomplete end face gear ring 12, so that when the cutter disc 3 rotates, the transmission gear 8 can drive the mounting tube 5 and the tool body 6 to rotate 360 ​​degrees, so that the industrial camera 19 installed on the mounting plate 1 can fully shoot and detect the cutting edge of the tool body 6, thereby ensuring the stability of the tool body 6 during use;

[0047] When the cutting edge of the tool body 6 is detected to be damaged, an external alarm is used to alert the operator to replace the tool body 6;

[0048] When the output end of the stepper motor 16 rotates, the roller 17 is driven to rotate through the pulley 21 and the belt 22, so that the transmission belt 18 sleeved on the outer surface of the roller 17 can drive the industrial camera 19 to move synchronously with the movement of the tool body 6, so as to ensure the clarity and accuracy of the industrial camera 19 shooting the edge of the tool body 6;

[0049] After the conductive column 25 installed on the tool disc 3 contacts the conductive sheet 26, the power of the air pump 24 is connected to make the air pump 24 blow air into the nozzle pipe group 23, so that the nozzle pipe group 23 blows out gas to clean the impurities adhered to the tool body 6, so as to prevent the impurities from blocking the cutting edge of the tool body 6 and affecting the shooting and detection effect of the industrial camera 19.

[0050] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
