[0005] To achieve the above purpose, the technical scheme adopted by the utility model is:

[0006] A numerical control blade edge passivation device, comprising a sand blasting passivation machine, further comprising a supporting mechanism, the sand blasting passivation machine is internally provided with the supporting mechanism, the supporting mechanism comprises a sand blasting pipe, a perspective glass, a slot, a rubber pad, a supporting plate, a partition plate, a seat, a rotating ring and a motor, the sand blasting pipe is installed on the inner wall top end of the sand blasting passivation machine, and the perspective glass is inlaid on one side of the surface of the sand blasting passivation machine, the slot is formed on the surface of the sand blasting passivation machine at the bottom position of the perspective glass, and the rubber pad is bonded on the inner wall of the slot, the supporting plate is inserted into the slot in the horizontal direction, and the partition plate is fixedly connected on both ends of the supporting plate on the top and abuts against the inner wall of the slot, the seat is arranged on the top of the supporting plate and corresponds to the sand blasting pipe, and the rotating ring is installed in the seat, the motor is installed in the supporting plate, and the power output end of the motor is connected with the power input end of the rotating ring.

[0007] Furthermore, it also includes an auxiliary mechanism. The sandblasting and passivation machine is internally equipped with this auxiliary mechanism, which includes an air inlet pipe, a diverter pipe, a nozzle, a solenoid valve, a spring, a pressure plate, a protruding post, and a pressure switch. An air inlet pipe connected to an air supply device is located on one side of the sandblasting and passivation machine surface. A diverter pipe extending to the inner wall of the sandblasting and passivation machine near the slot is installed at the end of the air inlet pipe. A nozzle facing the interior of the sandblasting and passivation machine is located on the surface of the diverter pipe. A solenoid valve is installed at the connection between the air inlet pipe and the diverter pipe. A pressure plate is movably connected to the inside of the sandblasting and passivation machine housing near the top of the slot via a spring. A nozzle penetrating the spring and extending from the surface of the pressure plate is fixedly connected to the surface of the pressure plate. The protrusion inside the slot is connected to a pressure switch located inside the casing of the sandblasting and passivation machine, corresponding to the pressure plate. The air inlet pipe is connected to an external high-pressure air supply device. The high-pressure airflow passes through the split pipe and blows from the nozzle to the inside of the sandblasting and passivation machine. The split pipe and nozzle are located near the slot. In the tool cleaning state or tool installation and removal state, since the partition is located inside the slot, it pushes the protrusion, causing the pressure plate to separate from the pressure switch and pausing the air blowing. When the tray is pulled outward, the spring drives the pressure plate to reset, the pressure switch is opened, and the solenoid valve is opened through the controller. The high-pressure airflow blows in and can sweep away the sand and gravel on the surface of the tray, causing it to fall off and preventing the sand and gravel from being carried out of the equipment.

[0008] Furthermore, an end plate is fixedly connected to one end of the pallet outside the sandblasting and passivation machine. A handle is fixedly connected to the side of the end plate away from the pallet, and a control switch is installed on the surface of the handle.

The handle structure facilitates the horizontal pulling of the pallet, and the control switch enables the starting and closing of the motor.

[0009] Furthermore, the motor current input terminal is equipped with a power supply line extending to the outside of the tray, and a sheath is installed between the end of the tray and the inner wall of the sandblasting passivation machine, with the power supply line passing through the inside of the sheath. The power supply line provides operating current to the motor, and the sheath located on the outer periphery of the power supply line can provide good protection for the power supply line and avoid the impact of sandblasting.

[0010] Furthermore, a controller is provided inside the casing of the sandblasting and passivation machine near the pressure switch. The signal output terminal of the controller is connected to the control terminal of the solenoid valve through the controller. The opening and closing signal of the pressure switch is fed back to the controller, and the controller regulates the opening and closing of the solenoid valve.

[0011] Compared with the prior art, this utility model has the following advantages: The sandblasting and passivation machine uses sandblasting rollers to passivate the cutting edges of CNC cutting tools. The sandblasting and passivation process can be observed through a viewing glass. The support plate can be horizontally pulled out along the slot. When a tool needs to be placed, the support plate body is removed, the tool to be processed is inserted into the support and engaged with the rotating ring, and then the support plate is moved into the sandblasting and passivation machine. During the sandblasting process, the motor is controlled to drive the rotation of the rotating ring and the tool, so that the sandblasting can perform comprehensive and uniform passivation treatment on the tool cutting edges. When the support plate is pulled out and inserted into place, the partition on the top of the support plate will fit into the slot, and the sealing of the connection is ensured by the fit with the rubber gasket, preventing sand leakage. Compared to existing passivation equipment, this new semi-automatic system features a simpler structure, lower cost, reduced manual operation, and ensures uniform passivation of the tools. The air inlet pipe connects to an external high-pressure air supply. High-pressure airflow passes through a splitter pipe and blows from the nozzle towards the inside of the sandblasting passivation machine. The splitter pipe and nozzle are positioned near the slot. During tool cleaning or tool installation / removal, the partition plate, located inside the slot, pushes against the protruding column, causing the pressure plate to separate from the touch switch, pausing the airflow. When the tray is pulled outwards, the spring resets the pressure plate, opening the touch switch. This, via the controller, opens the solenoid valve, allowing high-pressure airflow to sweep away the sand and gravel on the tray surface, preventing it from being carried out of the equipment.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-4 As shown, a CNC cutting tool edge passivation device includes a sandblasting passivation machine 1 and a support mechanism 2. The support mechanism 2 is provided inside the sandblasting passivation machine 1. The support mechanism 2 includes a sandblasting pipe 201, a transparent glass 202, a slot 203, a rubber pad 204, a support plate 205, a partition 206, a support base 207, a rotating ring 208, and a motor 209. The sandblasting pipe 201 is installed at the top of the inner wall of the sandblasting passivation machine 1, and the transparent glass 202 is embedded in one side of the surface of the sandblasting passivation machine 1. The surface of the sandblasting passivation machine 1 is located on the transparent glass 205. 2. A slot 203 is provided at the bottom position, and a rubber pad 204 is adhered to the inner wall of the slot 203. A support plate 205 is inserted horizontally inside the slot 203, and a partition plate 206 that fits the inner wall of the slot 203 is fixedly connected to both ends of the top of the support plate 205. A support seat 207 for supporting the CNC cutting tool to be processed is provided at the top of the support plate 205 corresponding to the position of the sandblasting pipe 201, and a rotating ring 208 is installed inside the support seat 207. A motor 209 is installed inside the support plate 205, and the power output end of the motor 209 is connected to the power input end of the rotating ring 208.

[0019] The system also includes an auxiliary mechanism 3. The sandblasting and passivation machine 1 is internally equipped with this auxiliary mechanism 3, which includes an air inlet pipe 301, a diverter pipe 302, a nozzle 303, a solenoid valve 304, a spring 305, a pressure plate 306, a protrusion 307, and a contact switch 308. An air inlet pipe 301 connected to an air supply device is located on one side of the surface of the sandblasting and passivation machine 1. A diverter pipe 302 extending to the inner wall of the sandblasting and passivation machine 1 near the slot 203 is installed at the end of the air inlet pipe 301. A nozzle 303 facing the interior of the sandblasting and passivation machine 1 is installed on the surface of the diverter pipe 302. A solenoid valve 304 is installed at the connection between the air inlet pipe 301 and the diverter pipe 302. A pressure plate 306 is movably connected to the interior of the sandblasting and passivation machine 1 near the top of the slot 203 via a spring 305. A through-spring 307 is fixedly connected to the surface of the pressure plate 306. The protrusion 307 extends into the slot 203. A pressure switch 308 is provided inside the housing of the sandblasting and passivation machine 1 at a position corresponding to the pressure plate 306. The air inlet pipe 301 is connected to an external high-pressure air supply device. The high-pressure airflow passes through the diverter pipe 302 and blows from the nozzle 303 to one side of the sandblasting and passivation machine 1. The diverter pipe 302 and the nozzle 303 are located near the slot 203. In the tool cleaning state or the tool installation and removal state, since the partition plate 206 is located inside the slot 203, it pushes the protrusion 307, causing the pressure plate 306 to separate from the pressure switch 308, and the air blowing stops. When the support plate 205 is pulled outward, the spring 305 drives the pressure plate 306 to reset, and the pressure switch 308 is opened. The controller 309 opens the solenoid valve 304, and the high-pressure airflow blows in to sweep away the sand and gravel on the surface of the support plate 205 and make it fall down, so as to prevent the sand and gravel from being carried out of the equipment.

[0020] The pallet 205 is fixedly connected to an end plate 210 at one end outside the sandblasting and passivation machine 1. A handle 211 is fixedly connected to the side of the end plate 210 away from the pallet 205, and a control switch 212 is installed on the surface of the handle 211. The control terminal of the control switch 212 is connected to the control terminal of the motor 209. A power supply line 213 extending to the outside of the pallet 205 is installed at the current input terminal of the motor 209. A sheath tube 214 is installed between the end of the pallet 205 and the inner wall of the sandblasting and passivation machine 1, and the power supply line 213 passes through the inside of the sheath tube 214. The handle 211 structure facilitates the horizontal pulling of the pallet 205. The control switch 212 can control the start and stop of the motor 209. The power supply line 213 provides operating current to the motor 209. The sheath tube 214 located on the outer periphery of the power supply line 213 can provide good protection for the power supply line 213 and avoid the impact of sandblasting.

[0021] Inside the casing of the sandblasting and passivation machine 1, near the pressure switch 308, there is a controller 309. The signal output terminal of the controller 309 is connected to the control terminal of the solenoid valve 304. The opening and closing signal of the pressure switch 308 is fed back to the controller 309, and the controller 309 regulates the opening and closing of the solenoid valve 304.

[0022] It should be noted that this utility model is a CNC cutting tool edge passivation device. During operation, the sandblasting passivation machine 1 uses a sandblasting roller to passivate the cutting edge of the CNC cutting tool through sandblasting. The sandblasting passivation process can be observed through the viewing glass 202. The support plate 205 can be horizontally pulled out along the slot 203. When a tool needs to be placed, the main body of the support plate 205 is removed, and the tool to be processed is inserted into the support 207 and engaged with the rotating ring 208. Then, the support plate 205 is moved into the sandblasting passivation machine 1. During the sandblasting process, the motor 209 is controlled to run, driving the rotating ring 208 and the tool to rotate, so that the sandblasting can perform a comprehensive and uniform passivation treatment on the cutting edge of the tool. When the support plate 205 is pulled out and inserted into place, the partition plate 206 on the top of the support plate 205 will fit into the slot 203, and the sealing of the connection is ensured by the fit with the rubber gasket 204 to prevent sand and gravel from leaking out. Compared to existing passivation equipment, this machine adopts semi-automatic operation, has a simple structure, lower cost, reduces manual operation, and ensures uniform passivation of the tools. The air inlet pipe 301 is connected to an external high-pressure air supply device. The high-pressure airflow passes through the split pipe 302 and blows into the inside of the sandblasting passivation machine 1 from the nozzle 303. The split pipe 302 and the nozzle 303 are located near the slot 203. In the tool cleaning state or tool installation and removal state, since the partition plate 206 is located inside the slot 203, it pushes the protrusion 307, causing the pressure plate 306 to separate from the touch switch 308, pausing the air blowing. When the support plate 205 is pulled outward, the spring 305 drives the pressure plate 306 to reset, the touch switch 308 is opened, and the solenoid valve 304 is opened through the controller 309. The high-pressure airflow blows in and can sweep away the sand and gravel on the surface of the support plate 205, making them fall off and preventing the sand and gravel from being carried out of the equipment.
