[0002] CNC lathe machining safety devices are crucial components used to ensure the safety of CNC lathe operators and prevent accidents caused by cutting spatter, equipment malfunction, or misoperation during machining. Their core functions include isolating hazardous areas, blocking spatter, monitoring operating status, and providing emergency protection. However, existing CNC lathe machining safety devices have some shortcomings, such as: The protective device for CNC lathes used for machining guide wheels, with application number CN202123184516.0, has the advantages of reducing noise and cleaning the observation window, which is beneficial for workers to observe the work. However, in actual use, because the lathe is in a relatively sealed state, it may be difficult to expel toxic exhaust gases during the machining of parts, which may cause the parts to be affected by exhaust gases or debris during machining. Therefore, we propose a protective device for CNC lathe machining to solve the problems mentioned above. Utility Model Content

[0003] The purpose of this utility model is to provide a protective device for CNC lathe machining, so as to solve the problem mentioned in the background art that most protective devices for CNC lathe machining on the market cause parts to be affected by exhaust gas or debris during machining.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a protective device for CNC lathe machining, comprising a device body and an integrated control board disposed on the top of the device body; The device body is equipped with a drive mechanism inside, and the right end of the drive mechanism is connected to the protection mechanism and the exhaust mechanism.

The right end of the fourth bevel gear is provided with a fan blade, and a waste trough is provided inside the device body.

[0005] The drive mechanism drives the protective mechanism to operate, which in turn enables the reciprocating threaded shaft in the protective mechanism to drive the threaded sleeve and the glass protective cover to seal the empty slot at the front end of the device body. Subsequently, the drive mechanism drives the exhaust mechanism to operate, which causes the fan blades to discharge the exhaust gas inside the device body. It can also blow the debris to the waste trough for collection by wind power, thereby increasing the protection of the equipment when processing parts.

[0006] As a preferred technical solution of this utility model, the front end of the main body of the device is provided with a cleaning cloth, and the cleaning cloth can fit against the inside of the glass protective cover, and a sliding rod is slidably connected to the inside of the threaded sleeve.

[0007] The above technical solution enables the threaded sleeve to move more stably when moving the glass protective cover, thereby avoiding the threaded sleeve from shifting during movement.

[0008] As a preferred technical solution of this utility model, the main body of the device is connected to the drive mechanism, and the drive mechanism includes a drive motor, which is connected to an integrated control board. The right end of the drive motor is provided with a first sprocket, and a chain is engaged on the outside of the first sprocket. The other end of the chain is engaged with a second sprocket. Both the right end of the first sprocket and the right end of the second sprocket are provided with ratchet groups.

[0009] The above technical solution enables the drive mechanism to operate more stably when driving the protection mechanism and the exhaust mechanism, thereby increasing the stability of the equipment during operation.

[0010] As a preferred technical solution of this utility model, the second sprocket is connected to the inside of the device body through a bearing seat, and the ratchet group includes a first ratchet, and the right end of the first ratchet is engaged with a second ratchet. The right end of the second ratchet is connected to a spring shaft, and the ratchet group at the right end of the first sprocket and the ratchet group at the right end of the second sprocket face opposite directions.

[0011] The above technical solution enables the drive mechanism to be more stable when controlling the protection mechanism or the exhaust mechanism, thereby increasing the controllability of the equipment during operation.

[0012] As a preferred technical solution of this utility model, the right end of the second sprocket is connected to the first bevel gear through a ratchet assembly, and the rear end of the first bevel gear is engaged with the second bevel gear. The second bevel gear is connected to the third bevel gear through a drive shaft, and the fan blade is rotatably connected to the inside of the device body.

[0013] The above technical solution enables the second sprocket to operate more stably when driving multiple sets of fan blades simultaneously, thereby increasing the efficiency of the equipment in discharging exhaust gas from the main body of the device.

[0014] As a preferred technical solution of this utility model, an air inlet valve is provided at the rear end of the main body of the device, and an air outlet valve is installed at the right end of the main body of the device, and the air outlet valve is located at the top of the waste trough.

[0015] The above technical solution makes it easier to discharge gas inside the device, thus avoiding the problem of the waste gas being unable to be discharged due to the device being sealed inside.

[0016] As a preferred technical solution of this utility model, the main body of the device is connected to the second bevel gear through a bearing seat, and the air intake valve is located at the rear end of the fan blade.

[0017] The above technical solution enables the second bevel gear to rotate more stably, thereby increasing the stability of the equipment during operation.

[0018] Compared with the prior art, the beneficial effects of this utility model are: by driving the protective mechanism through the drive mechanism, the reciprocating threaded shaft in the protective mechanism can drive the threaded sleeve and the glass protective cover to seal the empty slot at the front end of the device body. Then, the drive mechanism drives the exhaust mechanism to run, so that the fan blades can discharge the exhaust gas inside the device body and blow the debris to the waste trough for collection by wind power, thereby increasing the protection of the equipment when processing parts. Furthermore, by setting up the sliding rod, the threaded sleeve can be made more stable when moving the glass protective cover, thereby avoiding the threaded sleeve from shifting during movement. Furthermore, the design of inlet and outlet valves makes it easier to discharge gas from the main body of the device, thus avoiding the problem of the exhaust gas being unable to be discharged due to the internal sealing of the main body of the device.

[0022] To address the problem that existing protective devices used in CNC lathe machining can cause parts to be affected by exhaust gases or debris during machining, the following solution is disclosed. Please refer to [link / reference]. Figures 1-7 This utility model provides a technical solution: a protective device for CNC lathe machining, including a device body 1 and an integrated control board 2 disposed on the top of the device body 1; The device body 1 is equipped with a drive mechanism inside, and the right end of the drive mechanism is connected to the protection mechanism and the exhaust mechanism. The protection mechanism includes a reciprocating threaded shaft 10, and a threaded sleeve 11 is provided on the outside of the reciprocating threaded shaft 10. A glass protective cover 12 is provided at the front end of the threaded sleeve 11, and the glass protective cover 12 is slidably connected to the front end of the device body 1. The device body 1 is connected to the exhaust mechanism, and the exhaust mechanism includes a third bevel gear 16, and a fourth bevel gear 17 meshes with the right end of the third bevel gear 16. The right end of the fourth bevel gear 17 is provided with a fan blade 18, and a waste trough 20 is provided inside the device body 1. The front end of the device body 1 is provided with a cleaning cloth, which can fit against the inner side of the glass protective cover 12. A sliding rod 13 is slidably connected to the inner side of the threaded sleeve 11. The device body 1 is connected to the drive mechanism, which includes a drive motor 3 and is connected to the integrated control board 2. The right end of the drive motor 3 is provided with a first sprocket 4, and a chain 5 is engaged on the outer side of the first sprocket 4. The other end of the chain 5 is engaged with a second sprocket 6. Both the right end of the first sprocket 4 and the right end of the second sprocket 6 are provided with ratchet groups. The second sprocket 6 is connected to the inside of the device body 1 through a bearing seat, and the ratchet group includes a first ratchet 7, and the right end of the first ratchet 7 is engaged with a second ratchet 8. The right end of the second ratchet 8 is connected to a spring shaft 9, and the ratchet group at the right end of the first sprocket 4 and the ratchet group at the right end of the second sprocket 6 face opposite directions. The right end of the second sprocket 6 is connected to the first bevel gear 14 via a ratchet assembly, and the rear end of the first bevel gear 14 is engaged with the second bevel gear 15. The second bevel gear 15 is connected to the third bevel gear 16 via a drive shaft, and the fan blade 18 is rotatably connected to the inside of the device body 1. An air inlet valve 19 is provided at the rear end of the main body 1, and an air outlet valve 21 is installed at the right end of the main body 1. The air outlet valve 21 is located at the top of the waste trough 20. The main body 1 is connected to the second bevel gear 15 through a bearing seat, and the air inlet valve 19 is located at the rear end of the fan blade 18.

[0023] Working principle: When using the protective device for machining on this CNC lathe, first connect the equipment power supply and the power grid to supply power, then make the drive mechanism drive the protective mechanism to run, thereby making the reciprocating threaded shaft 10 drive the threaded sleeve 11 and the glass protective cover 12 to move, so that the glass protective cover 12 seals the empty groove at the front end of the device body 1. At the same time, make the drive mechanism drive the exhaust mechanism to run, thereby making the third bevel gear 16 drive the fourth bevel gear 17 to rotate, thereby making the fourth bevel gear 17 drive the fan blade 18 to rotate, so that the fan blade 18 exhausts the exhaust gas inside the device body 1. When the drive mechanism rotates in the forward direction, the drive motor 3 will drive the first sprocket 4 to rotate in the forward direction, thereby causing the ratchet group at the right end of the first sprocket 4 to engage, that is, the first ratchet 7 and the second ratchet 8 to engage. The second ratchet 8 will then drive the reciprocating threaded shaft 10 to rotate through the spring shaft 9. Since the ratchet group at the right end of the second sprocket 6 is facing the opposite direction to the ratchet group at the right end of the first sprocket 4, the ratchet group at the right end of the second sprocket 6 will disengage, that is, the first ratchet 7 and the second ratchet 8 will disengage. The second ratchet 8 will then retract under the drive of the spring shaft 9. When the drive motor 3 rotates in the reverse direction, the ratchet assembly at the right end of the second sprocket 6 will engage, thereby causing the second sprocket 6 to drive the first bevel gear 14 to rotate. At the same time, the first bevel gear 14 will also drive the second bevel gear 15 and the third bevel gear 16 to rotate. When exhausting air inside the main body 1, it will be discharged through the exhaust valve 21, and the debris will also be blown into the waste trough 20 for collection.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
