Description

Technical Field

[0001] This invention relates to the field of CNC 3D probe technology, specifically to an online inspection method for CNC probes. Background Technology

[0002] Machining equipment (such as machining centers) can process workpieces (e.g., cutting, surface treatment), and is therefore widely used in various fields. Generally, machining equipment includes a tool holder and a motor to drive the tool holder's rotation. The tool holder contains a cutting tool; therefore, during operation, the motor controls the tool holder's rotation to drive the cutting tool for cutting. In other words, most machining equipment on the market only has machining functions. However, to enhance functionality, CNC (computer-controlled automated machine tool) 3D probes are now installed in the machining handle of machining equipment. These CNC 3D probes collect data from the machined workpiece to identify problematic parts.

[0003] When a CNC 3D probe is performing data acquisition, the data collected is uploaded to the controller to provide information to the backend, allowing the backend to identify problematic workpieces. Since the CNC 3D probe is an external component of the machining equipment, it requires power to both the controller and the probe itself. However, traditionally, wired power is used, which is aesthetically unappealing, and the wires can easily interfere with the probe's operation, significantly reducing work quality.

[0028] 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 some embodiments of the present invention, and not all 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.

[0029] like Figure 1 As shown, this invention discloses an online inspection method for CNC probes, which includes the following steps:

[0030] Step S101: When it is determined that the processing equipment needs to use a 3D probe for data acquisition, determine whether the cutting tool in the processing tool holder of the processing equipment has been removed.

[0031] like Figure 2-8 As shown, the processing equipment has a rotatable processing tool holder 20, and the 3D side head 10 and the cutter are detachably mounted at the bottom of the processing tool holder 20, so that the 3D side head 10 and the cutter can move synchronously with the processing tool holder 20.

[0032] Furthermore, the processing equipment includes a fixing member 13, and a controller 11 is installed in the fixing member 13. It should be understood that the fixing member 13 has a through hole, and the processing tool holder 20 passes through the through hole.

[0033] Step S102: If it is determined that the cutter in the machining tool holder of the machining equipment has been removed, determine whether the 3D side head is inserted into the machining tool holder of the machining equipment.

[0034] In this embodiment, the bottom end of the processing tool holder 20 of the processing equipment is provided with a receiving slot for holding the cutting tool or the 3D side head 10. The receiving slot is provided with an identifier, the cutting tool is provided with a first ID code, and the 3D side head 10 is provided with a second ID code.

[0035] Furthermore, this online inspection method for CNC probes also includes:

[0036] Step S1021: When an inserted object is detected in the receiving slot of the machining tool holder 20 of the machining equipment, the identifier is activated to identify the ID code of the object.

[0037] It should be understood that the top wall of the card slot is equipped with a trigger button for triggering the recognition to start working. When an object is inserted into the card slot, the object presses the trigger button to trigger the recognition to start working. In other words, when an object is inserted into the card slot, the object will press the trigger button, and the trigger button will trigger the recognition to start working.

[0038] Step S1022: When the object is identified to have a first ID code, it is determined that the cutter is inserted into the receiving card slot. When the object is identified to have a second ID code, it is determined that the 3D probe 10 is inserted into the receiving card slot.

[0039] In other words, in step S1022, if the identifier recognizes that the object has a first ID code, it determines that the object inserted into the receiving card slot is a cutter; if the identifier recognizes that the object has a second ID code, it determines that the object inserted into the receiving card slot is a 3D probe.

[0040] In this embodiment, a protective housing 14 is provided outside the 3D side head 10, and a connector 17 is provided in the protective housing 14, one end of which is electrically connected to the 3D side head 10.

[0041] Step S103: If it is determined that the 3D side head 10 is inserted into the machining tool holder of the machining equipment, then control the machining tool holder of the machining equipment to rotate, so as to drive the 3D side head 10 to rotate.

[0042] It should be understood that since the protective housing 14 is located outside the 3D side head 10, when the 3D side head 10 rotates, the protective housing 14 and the connecting parts 17 outside it also rotate synchronously with the 3D side head 10.

[0043] Step S104: Determine whether the connector 17 has rotated to the position below the fixing member 13.

[0044] It should be understood that the horizontal plane where the fastener 13 is located is higher than the horizontal plane where the connector 17 is located.

[0045] In this embodiment, the bottom surface of the fixing member 13 is provided with an extension block 15, and a movable block 16 is provided in the extension block 15 for vertical movement. The movable block 16 is provided with a waterproof plug 12 for electrical connection with the processing equipment and a controller 11, and the waterproof plug 12 is electrically connected to the controller 11. It should be understood that since the movable block 16 is vertically movable in the extension block 15, the distance between the movable block 16 and the connecting member 17 can be finely adjusted as needed.

[0046] Furthermore, the movable block 16 is provided with a receiving space 160 and a cover plate 163 for covering the receiving space 160, wherein the controller 11 is disposed in the receiving space 160 and the waterproof plug 12 is disposed in the cover plate 163.

[0047] In this embodiment, the fixing member 13 is provided with a first threaded hole, in which a first lead screw is threadedly connected. The bottom end of the first lead screw rotates and is locked in the moving block 16. The extension block 15 is provided with a receiving groove 151. The moving block 16 is slidably disposed in the receiving groove 151. The top of the fixing member 13 is provided with a first drive motor. The shaft of the first drive motor is provided with a first gear. The top end of the first lead screw is provided with a second gear that meshes with the first gear.

[0048] Furthermore, the online detection method for the CNC probe also includes: when it is determined that the distance between the moving block 16 and the connector 17 needs to be finely adjusted, controlling the first drive motor to work, so as to drive the first lead screw to rotate through the first drive motor, so as to drive the moving block 16 to slide in the receiving slide 151, so as to adjust the distance between the moving block 16 and the connector 17.

[0049] Step S105: If it is determined that the connector 17 has rotated to the bottom of the fixing member, then it is determined whether the connector 17 and the controller in the fixing member 13 are electrically connected.

[0050] In this embodiment, the connector 17 is provided with a first conductive strip and a second conductive strip that are electrically connected to the 3D side head 10. The top surface of the other end of the connector 17 is provided with a first conductive post 171 that is electrically connected to the first conductive strip and a second conductive post 172 that is electrically connected to the second conductive strip. The bottom surface of the moving block 16 is provided with a first ejector pin 161 that is electrically connected to the controller 11 and a second ejector pin 162 that is electrically connected to the controller 11. The first ejector pin 161 corresponds to the first conductive post 171, and the second ejector pin 162 corresponds to the second conductive post 172.

[0051] Furthermore, this online inspection method for CNC probes also includes:

[0052] Step S1051: When the other end of the connector 17 rotates to the bottom of the moving block 16, determine whether the first ejector pin 161 and the first conductive post 171 are electrically connected and whether the second ejector pin 162 and the second conductive post 172 are electrically connected.

[0053] Step S1052: If it is determined that the first ejector pin 161 is not electrically connected to the first conductive post 171 and the second ejector pin 162 is not electrically connected to the second conductive post 172, then the machining tool holder of the machining equipment is slowly rotated, and the steps of determining whether the first ejector pin 161 is electrically connected to the first conductive post 171 and whether the second ejector pin 162 is electrically connected to the second conductive post 172 are continued to be executed.

[0054] Step S1053: If it is determined that the first ejector pin 161 is electrically connected to the first conductive post 171 and the second ejector pin 162 is electrically connected to the second conductive post 172, then the machining tool holder of the control machining equipment is stopped rotating.

[0055] In this embodiment, the bottom end of the movable block 16 is provided with a first through hole and a second through hole that communicate with the receiving space 160. The first through hole corresponds to the first conductive post 171, and the second through hole corresponds to the second conductive post 172. The first ejector pin 161 can be raised and lowered in the first through hole, and the second ejector pin 162 can be raised and lowered in the second through hole.

[0056] Furthermore, this online inspection method for CNC probes also includes:

[0057] Step S201: While controlling the rotation of the machining tool holder 20 of the machining equipment, determine whether the first through hole has rotated to be directly above the first conductive post 171.

[0058] It should be understood that when the first through hole is rotated to be directly above the first conductive post 171, the second through hole is also rotated to be directly above the second conductive post 172.

[0059] Step S202: When the first through hole is rotated to be directly above the first conductive post 171, the machining tool holder 20 of the machining equipment is controlled to stop rotating, and the first ejector pin 161 is controlled to descend from the first through hole and the second ejector pin 162 is controlled to descend from the second through hole, so that the first ejector pin 161 is electrically connected to the first conductive post 171 and the second ejector pin 162 is electrically connected to the second conductive post 172.

[0060] Furthermore, a first spring is installed inside the first through hole, with one end of the first spring fixedly positioned at the top of the first through hole. One end of the first ejector pin 161 is fixedly connected to the other end of the first spring. One end of the first ejector pin 161 is electrically connected to the controller 11 via a first wire. A second spring is installed inside the second through hole, with one end of the second spring fixedly positioned at the top of the second through hole. One end of the second ejector pin 162 is fixedly connected to the other end of the second spring. One end of the second ejector pin 162 is electrically connected to the controller 11 via a second wire. It should be understood that under normal circumstances, a small portion of the other end of the first ejector pin 161 and a small portion of the other end of the second ejector pin 162 are exposed outside the second through hole. The first and second springs are mainly for cushioning purposes.

[0061] Step S106: If it is determined that the connector 17 is electrically connected to the controller in the fixture 13, the control processing equipment supplies power to the controller so as to supply power to the 3D side head 10 through the connector 17 via the controller.

[0062] It should be understood that when the first ejector pin 161 is electrically connected to the first conductive post 171 and the second ejector pin 162 is electrically connected to the second conductive post 172, the controller 11 supplies power to the 3D side head 10 (the processing equipment supplies power to the controller 11 through the waterproof plug 12), so that the 3D side head 10 can perform data acquisition, and the data acquired by the 3D side head 10 can be uploaded through the controller 11. In this way, there is no need for additional wires to supply power to the 3D side head 10 and the controller 11, which is aesthetically pleasing and also effectively improves the work quality.

[0063] It is worth noting that the controller in this embodiment is electrically connected to the processing equipment via an automatic valve. Under normal circumstances (i.e., when it is determined that the controller in the connector 17 and the fixing member 13 are not connected), the automatic valve is open, causing the processing equipment to disconnect from the controller. When it is detected that the controller in the connector 17 and the fixing member 13 are electrically connected, the automatic valve is controlled to open, so that the processing equipment is connected to the controller, so as to supply power to the controller and the 3D side head 10 through the processing equipment.

[0064] Step S107: Control the 3D probe 10 to work and collect data from the workpiece, and upload the data collected by the 3D probe 10 through the controller.

[0065] It is worth noting that in other embodiments, the bottom end of the movable block 16 is also provided with a third through hole 164, wherein the controller 11 is electrically connected to an indicator light 165, and the indicator light 165 is movably mounted in the third through hole 164.

[0066] Furthermore, the online detection method for the CNC probe also includes: when the machining tool holder of the machining equipment drives the 3D side head 10 to rotate, the control indicator light 165 extends from the third through hole 164, and illuminates when the first ejector pin 161 is electrically connected to the first conductive post 171 and the second ejector pin 162 is electrically connected to the second conductive post 172. That is to say, under normal circumstances, the indicator light 165 is not exposed; it only extends from the third through hole 164 when the 3D side head 10 needs to be activated to collect data. The indicator light 165 illuminates when the first ejector pin 161 is electrically connected to the first conductive post 171 and the second ejector pin 162 is electrically connected to the second conductive post 172 to remind the operator that the connector 17 and the controller in the fixing member 13 are successfully electrically connected.

[0067] Additionally, in other embodiments, such as Figure 9 As shown, the bottom end of the moving block 16 is also provided with a third through hole 164, in which a transmitter 1641 electrically connected to the controller 11 is provided. The other end of the connector 17 is provided with a fourth through hole 173 corresponding to the third through hole 164, in which a receiver 174 is provided. The top end of the first pin 161 is connected to a first buffer spring 1611, and the top end of the second pin 162 is connected to a second buffer spring 1621. It should be understood that the controller 11 will only supply power to the transmitter 1641 when the rotation of the 3D head 10 is detected. A rechargeable battery for powering the receiver 174 can be provided in the connector 17 (the rechargeable battery can be charged when the controller 11 charges the 3D head 10). After receiving the command transmitted by the transmitter 1641, the receiver 174 will send back a feedback signal to indicate that it has been received.

[0068] Furthermore, the receiving space 160 of the moving block 16 is equipped with a second drive motor electrically connected to the controller 11, a connecting block 166 connected to the first buffer spring 1611 and the second buffer spring 1621 respectively, and a lifting rod 168 connected to the connecting block 166 via a pressure sensor 167. The lifting rod 168 has serrations along its length, and a third gear 1681 is provided in the rotating shaft of the second drive motor that meshes with the serrations of the lifting rod 168. That is to say, the first ejector pin 161 and the second ejector pin 162 can be driven to rise and fall synchronously by the lifting rod 168.

[0069] Preferably, when the fourth through hole 173 is rotated to be directly below the third through hole 164, the command transmitted by the transmitter 1641 is received by the receiver 174 (i.e., the transmitter 1641 is directly above the receiver 174). At this time, the first pin 161 in the first through hole is directly above the first conductive post 171, and the second pin 162 in the second through hole is directly above the second conductive post 172.

[0070] Furthermore, this online inspection method for CNC probes also includes:

[0071] Step S301: When the receiver 174 receives the command transmitted by the transmitter 1641, the processing tool holder 20 of the processing equipment is controlled to stop rotating, and the second drive motor is controlled to work to drive the lifting rod to descend.

[0072] It should be understood that under normal circumstances, the first ejector pin 161 is housed in the first through hole and the second ejector pin 162 is housed in the second through hole. Only when the other end of the connector 17 is rotated to the lower part of the moving block 16 (i.e. when the fourth through hole 173 is rotated to the lower part of the third through hole 164) will the first ejector pin 161 be controlled to extend out of the first through hole and the second ejector pin 162 be controlled to extend out of the second through hole. This can effectively protect the first ejector pin 161 and the second ejector pin 162.

[0073] Step S302: When it is determined that the first ejector pin 161 is electrically connected to the first conductive post 171, the second ejector pin 162 is electrically connected to the second conductive post 172, and when it is determined that the pressure value detected by the pressure sensor 167 reaches the preset pressure value, the second drive motor is controlled to stop working, and the step of controlling the processing equipment to supply power to the controller 11 is executed.

[0074] It should be understood that in step S301, during the process of controlling the second drive motor to work and drive the lifting rod to descend, the first pin 161 and the second pin 162 will continuously descend. When the first pin 161 just contacts the first conductive post 171 and the second pin 162 just contacts the second conductive post 172, the first pin 161 and the second pin 162 will continue to descend. At this time, the first buffer spring 1611 and the second buffer spring 1621 will be compressed, and the pressure sensor 167 can measure the pressure value of the compression. When it is determined that the pressure value detected by the pressure sensor 167 reaches the preset pressure value, the second drive motor is controlled to stop working. At this time, the first pin 161 and the second pin 162 stop, the first pin 161 is in close contact with the first conductive post 171, and the second pin 162 is in close contact with the second conductive post 172, resulting in better conductivity.
