Currently, most traditional machining centers feature cooling systems for cutting tools. Manual adjustment of the cooling pipe angle allows for cooling and cleaning during tooling of varying lengths. For machining processes requiring frequent tool changes, multiple manual adjustments of the cooling pipe angle are required, which consumes processing time and increases the workload of the operator. Furthermore, pausing the process to adjust the cooling pipe during machining poses potential safety risks. We offer an automatic spray system for machining centers. Utility Model Content

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0021] See also Figure 1-3 As shown, an automatic spray system for a machining center includes a fixed block 1 fixedly mounted on one side of a machining spindle, a mounting seat 2 being fixedly connected to the bottom position of one end of the fixed block 1, a connecting block 8 being rotatably mounted on one side of the mounting seat 2, and a spray head 9 being fixedly mounted on the end of the connecting block 8 away from the mounting seat 2;
[0022] The bottom of the fixed block 1 is also fixedly connected to the adjustment box 3, and a worm 4 is rotatably installed in the adjustment box 3. One end of the worm 4 is coaxially fixed with a bevel gear 6. A drive motor 5 is installed on the top of one end of the adjustment box 3. The output end of the drive motor 5 passes through the adjustment box 3 and is coaxially fixed with a bevel gear 2 7. The bevel gear 1 6 and the bevel gear 2 7 are meshed and driven together;
[0023] The mounting base 2 is located at the other side away from the connecting block 8 and is coaxially fixedly connected to the connecting block 8 with a worm gear 10. An opening is provided at the bottom of the end of the adjusting box 3 away from the driving motor 5. Through the opening, the worm gear 10 is engaged with the worm 4 for transmission.
[0024] Furthermore, an angle disc 11 is coaxially fixed to one side of the mounting seat 2 relative to the worm gear 10. A scale grid is evenly arranged on the angle disc 11. A pointer 12 is fixed at the rotation center of the connecting block 8. A laser sensor is provided at the end of the pointer 12. A photosensitive strain gauge is provided in each scale grid.
[0025] The liquid inlet end of the nozzle 9 is connected to a rubber bellows 13, and the end of the rubber bellows 13 away from the nozzle 9 is connected to a coolant input pipe 14;
[0026] Further, if Figure 4 As shown in the figure, the overall circuit connection of this sprinkler system primarily includes: GS1 switching power supply, QF1 circuit breaker, XT1 terminal block, CNC system, I / O module, splitter, and sprinkler unit. The switching power supply converts 220V AC power to 24V DC power, which is then supplied to the CNC system, I / O module, and sprinkler unit via the terminal block. The CNC system and I / O module are connected via XS1 and XS2 interface cables for I / O communication. The I / O module connects to the XS4 interface of the splitter via the XS3 interface for external output. The splitter's output terminals connect to the Y1, Y2, Y3, and Y4 terminals on the A4 sprinkler unit's JP1 interface, where binary combinations control the output angle.
[0027] When the utility model is in use, the tool length of the CNC machining center is targeted to measure the distance between the tool working part and the connecting block 8, and then the angle relationship between the tool working part and the nozzle is obtained. The corresponding tool is bound to the required nozzle angle through the PLC programming of the programmer. When a tool position in the tool magazine is changed, the required nozzle angle is read, so as to control the drive motor 5 to drive the worm 4 to rotate, and the worm gear 10 engaged with it rotates, thereby driving the connecting block 8 coaxially fixed with it to rotate, and then adjusting the angle of the nozzle 9 to the required nozzle angle. The current angle is determined by the position of the laser excitation on the photosensitive strain gauge. When the required nozzle angle is reached, the rotation of the drive motor 5 is stopped, and the self-locking effect of the worm gear 10 and the worm 4 is used to lock the current angle of the nozzle 9, and finally the automatic adjustment of the angle of the nozzle 9 is completed automatically according to the tool length.
