[0002] At present, in the processing of precision tools, in order to ensure the quality of the tools, a nano - coating needs to be applied to the tool surface. The coating, as a chemical barrier and a thermal barrier, reduces the diffusion and chemical reaction between the tool and the workpiece. During the spraying process, a fixing device is required.

[0003] A Chinese patent with the publication number CN219291715U discloses a quick - clamping and fixing device for PVD tool coatings, including a base, a support seat, a connecting rotating rod, a fixing plate, a docking plate, a clamping plate, a limiting seat, and a locking seat. The beneficial effects of the utility model are as follows: In this clamping device, by rotating the linkage screw rod to drive the threaded linkage of the limiting rod, the limiting rod is limited to slide in the notch on the locking seat. Through the sliding of the limiting rod, the limiting seat and the locking seat rotate synchronously in the opposite direction, thereby driving the left and right connecting rotating rods to rotate synchronously in the opposite direction, and then driving the two groups of fixing plates, docking plates, and clamping plates to rotate synchronously in the opposite direction as a whole, so as to quickly clamp and lock the tool to be subjected to PVD coating spraying between two adjacent clamping plates, realizing quick clamping and fixing. In the locking seat of this clamping device, a rectangular notch is arranged in a concave shape, a slider is slidably connected in the notch, and a locking rod is connected to the slider, enabling the staff to lock the linkage screw rod through the locking rod after clamping and locking the tool.

[0004] During the process of clamping and fixing the tool by the existing fixing device for coating spraying, by rotating the knob to control the clamping block for clamping and fixing, although it is relatively stable, it cannot quickly clamp the tool, resulting in low fixing efficiency.

Although it is relatively stable, it cannot quickly clamp the cutting tool, resulting in low fixing efficiency. By placing the milling cutter 20 with a coating at the center of the rotating plate 4, at this time, the control panel 5 controls the operation of the stepping motor 8. The stepping motor 8 drives the lead screw 7 to rotate at a high speed. The lead screw 7 drives the two groups of sliders 9 on it to move synchronously relative to each other. The two groups of sliders 9 drive the two groups of connecting blocks 10 to move synchronously relative to each other. The two groups of connecting blocks 10 drive the two groups of clamping blocks 11 to move synchronously relative to each other. The two groups of clamping blocks 11 move towards the milling cutter 20. During the process of approaching the milling cutter 20, the moving rod 15 on the clamping block 11 first contacts the milling cutter 20. The milling cutter 20 pushes the moving rod 15 into the moving groove 13. The moving rod 15 drives the limiting plate 14 to move in the moving groove 13. When the clamping block 11 is in contact with the milling cutter 20 instantaneously, the milling cutter 20 completely pushes the moving rod 15 into the moving groove 13.

The water pump 24 guides the coating material in the storage tank 23 into the water plate 21 and then sprays it out from the nozzle 22. The coating material is coated on the surface of the milling cutter 20. At the same time, the first motor 19 drives the rotating plate 4 to rotate. The rotating plate 4 drives the milling cutter 20 on it to rotate, realizing the full spraying of the milling cutter 20. This structure can quickly clamp the milling cutter 20, and the clamping force is appropriate, which is beneficial to improving the fixing efficiency and the protection of the cutting tool.

[0020] Working principle: During the process of clamping and fixing a cutting tool with the existing coating spraying fixing device, the clamping block is controlled to clamp and fix by rotating the knob. Although it is relatively stable, it cannot quickly clamp the cutting tool, resulting in low fixing efficiency. By placing the milling cutter 20 with a coating at the center of the rotating plate 4, at this time, the control panel 5 controls the operation of the stepping motor 8. The stepping motor 8 drives the lead screw 7 to rotate at a high speed. The lead screw 7 drives the two groups of sliders 9 on it to move relatively synchronously. The two groups of sliders 9 drive the two groups of connecting blocks 10 to move relatively synchronously. The two groups of connecting blocks 10 drive the two groups of clamping blocks 11 to move relatively synchronously. The two groups of clamping blocks 11 move towards the milling cutter 20. During the process of approaching the milling cutter 20, the moving rod 15 on the clamping block 11 first contacts the milling cutter 20. The milling cutter 20 pushes the moving rod 15 into the moving groove 13. The moving rod 15 drives the limiting plate 14 to move in the moving groove 13. When the clamping block 11 is in contact with the milling cutter 20, the milling cutter 20 completely pushes the moving rod 15 into the moving groove 13. The limiting plate 14 drives the first electrode sheet 16 to contact the second electrode sheet 17, so that the indicator light 12 on the clamping block 11 is turned on. The indicator light 12 sends an electrical signal to the control panel 5. When both groups of clamping blocks 11 are in contact with the milling cutter 20, the control panel 5 receives the second electrical signal. At this time, the control panel 5 controls the stepping motor 8 to stop operating. At this time, the clamping force of the two groups of clamping blocks 11 on the milling cutter 20 is appropriate, realizing the control of the clamping force, avoiding damage to the milling cutter 20 caused by excessive clamping force, realizing the protection of the milling cutter 20, and at the same time, the two groups of clamping blocks 11 quickly clamp the milling cutter 20, realizing efficient clamping and fixing; after the milling cutter 20 is clamped, the water pump 24 operates. The water pump 24 guides the coating material in the storage tank 23 into the water plate 21 and then sprays it out from the nozzle 22. The coating material is coated on the surface of the milling cutter 20. At the same time, the first motor 19 drives the rotating plate 4 to rotate. The rotating plate 4 drives the milling cutter 20 on it to rotate, realizing the full spraying of the milling cutter 20. This structure can quickly clamp the milling cutter 20, and the clamping force is appropriate, which is beneficial to improving the fixing efficiency and the protection of the cutting tool.
