[0031] Please refer to Figure 1 , an embodiment of the present utility model provides a telescopic spray device, including: a telescopic cylinder.

[0032] Please refer to Figure 1 and Figure 2 , the telescopic cylinder includes a cylinder block 10 and a piston rod 20. The piston rod 20 movably passes through the cylinder block 10. A spray channel 21 penetrating through both ends of the piston rod 20 is provided inside the piston rod 20. An inlet assembly 22 and a nozzle assembly 23 are respectively provided at both ends of the piston rod 20. After high-pressure gas and lubricating oil are mixed to form an oil mist, the oil mist is input into the inlet assembly 22, then the oil mist is conveyed to the nozzle assembly 23 through the spray channel 21, and then sprayed out from the nozzle assembly 23. The piston rod 20 telescopically moves relative to the cylinder block 10, so that the nozzle assembly 23 on the piston rod 20 moves relative to the cylinder block 10, thereby realizing the adjustment of the position of the nozzle assembly 23, enabling the nozzle assembly 23 to adapt to the tool position requirement of the cutting assembly 30 and spray the oil mist to the accurate position, so as to effectively realize cooling and lubrication, improve the machining quality and the service life of the cutting tool. When spraying is not required, the nozzle assembly 23 can be retracted away from the tool of the cutting assembly 30, thus avoiding affecting other processes or the layout of other structures. In addition, a spray channel 21 for conveying the oil mist is formed inside the piston rod 20, thereby reducing the conveying pipelines, simplifying the overall structure, making the overall structure more compact, and facilitating the installation of the telescopic spraying device.

[0033] Please refer to Figure 3 and Figure 4 , the inlet assembly 22 needs to be connected to the conveying pipeline of the oil mist. Since the piston rod 20 will move relative to the cylinder block 10, in some alternative embodiments, an air cavity 11 and a through hole 12 communicating with the air cavity 11 are provided inside the cylinder block 10. A first circumferential limiting portion 13 is formed on the inner wall of the through hole 12. The piston rod 20 movably passes through the air cavity 11 and the through hole 12. A second circumferential limiting portion 24 is formed on the piston rod 20. A part of the second circumferential limiting portion 24 is located in the through hole 12 and cooperates with the first circumferential limiting portion 13 to limit the rotation of the piston rod 20 relative to the through hole 12, thereby avoiding the rotation of the inlet assembly 22 relative to the conveying pipeline of the oil mist, and enabling the piston rod 20 to only translate relative to the cylinder block 10.

[0034] The specific structures of the first circumferential limiting portion 13 and the second circumferential limiting portion 24 can be designed according to actual needs. For example, in some alternative embodiments, the first circumferential limiting portion 13 is a plurality of corner grooves formed on the inner wall of the through hole 12, such that the cross-section of the through hole 12 is formed into a polygon at this time, and the plurality of corner grooves are arranged uniformly around the through hole 12. The second circumferential limiting portion 24 is a plurality of corner portions formed on the piston rod 20, such that the cross-section of the piston rod 20 is formed into a polygon matching the through hole 12 at this time, and the plurality of corner portions are arranged uniformly around the piston rod 20. The corner portions extend into the corner grooves to cooperate to limit the relative rotation of the piston rod 20 with respect to the through hole 12. Of course, the first circumferential limiting portion 13 can also be a convex block, and the second circumferential limiting portion 24 can be a sliding groove that slidably cooperates with the convex block. The convex block and the sliding groove cooperate to limit the relative rotation of the piston rod 20 with respect to the through hole 12.

[0035] In order to facilitate adjusting the limit position where the piston rod 20 of the telescopic cylinder stays, in some alternative embodiments, an adjusting ring 25 is provided on the piston rod 20, and a locking member 26 is provided on the adjusting ring 25. The adjusting ring 25 can move relative to the cylinder block 10 along the piston rod 20. The locking member 26 locks the adjusting ring 25 to the piston rod 20 to limit the relative movement of the adjusting ring 25 with respect to the piston rod 20. When the piston rod 20 moves relative to the cylinder block 10 such that the nozzle assembly 23 moves to a docking position away from the tool of the cutting assembly 30, a preset spacing distance is provided between the cylinder block 10 and the adjusting ring 25; when the piston rod 20 moves relative to the cylinder block 10 such that the nozzle assembly 23 moves towards the tool of the cutting assembly 30 to a working position, the adjusting ring 25 abuts against the cylinder block 10, thereby limiting the limit position of the piston rod 20, and further enabling the nozzle assembly 23 to accurately stay at the spraying position. By moving the adjusting ring 25 along the piston rod 20, the size of the preset spacing distance is adjusted, and further the limit position of the piston rod 20 is adjusted, thereby realizing the adjustment of the spraying position of the nozzle assembly 23. In this embodiment, the adjusting ring 25 is arranged around the piston rod 20, and both ends of the adjusting ring 25 are locked by the locking member 26. The locking member 26 is a threaded member. By adjusting the inner diameter of the adjusting ring 25 with the threaded member, the adjusting ring 25 is locked or loosened from the piston rod 20.

[0036] The specific structure of the nozzle assembly 23 can be designed according to actual needs. For example, in some alternative embodiments, the nozzle assembly 23 includes a nozzle head 231 and a universal shaping tube 232. The nozzle head 231 is connected to the end of the piston rod 20 through the universal shaping tube 232. The spraying channel 21 is communicated with the nozzle head 231 through the universal shaping tube 232. The universal shaping tube 232 can be bent to adjust the angle of the nozzle head 231, and further enable the nozzle head 231 to spray at a suitable position.

[0037] In some alternative embodiments, the nozzle 231 is detachably connected to the universal shaping tube 232, or the universal shaping tube 232 is detachably connected to the piston rod 20. In this embodiment, the nozzle 231 can be in threaded engagement with the universal shaping tube 232 to facilitate the disassembly of the nozzle 231, or the universal shaping tube 232 can be in threaded engagement with the piston rod 20 to facilitate the disassembly of the entire nozzle assembly 23. By disassembling the nozzle 231 or the nozzle assembly 23, it is convenient to replace nozzles 231 of different sizes.

[0038] Please refer to Figure 2 and Figure 5 , in some alternative embodiments, a plurality of mounting brackets 14 are provided on the side of the cylinder block 10, and the mounting brackets 14 facilitate the installation of the cylinder block 10 in a suitable position.

[0039] In some alternative embodiments, a first adjustment groove 15 is provided on the mounting bracket 14, and a plurality of first threaded locking members 16 are provided on the cylinder block 10. The first threaded locking members 16 are movably connected to the first adjustment groove 15 and can slide and rotate relative to the first adjustment groove 15. Sliding the first threaded locking members 16 along the first adjustment groove 15 can adjust the position of the cylinder block 10, and the cylinder block 10 can also rotate relative to the mounting bracket 14 to adjust the angle. After the first threaded locking members 16 are rotated, the cylinder block 10 can be locked to the mounting bracket 14.

The mounting seat 31 facilitates the installation of the telescopic spraying devices. In this embodiment, the cylinder block 10 is assembled with the mounting seat 31 through the mounting bracket 14. A plurality of telescopic spraying devices are arranged around the cutting assembly 30, thereby facilitating lubrication and cooling of the cutting tool of the cutting assembly 30 at multiple positions and improving the machining quality.
