Technical Field
[0001] This utility model relates to the field of lathe parts processing technology, and in particular to a protective device for parts processing on a CNC lathe. Background Technology
[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, grinding, reaming, boring, and other machining operations.
[0003] When grinding parts, the high-speed rotation of the grinding disc comes into contact with the parts, generating grinding sparks and fine debris. The high temperature of the grinding sparks can burn the skin of workers when they come into contact with them, and the fine debris can also affect the external environment. Existing processing equipment cannot effectively block them, thus affecting the user experience. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a protective device for machining parts on a CNC lathe, comprising a lathe body 1, uprights 3 fixedly connected to the four corners of the top surface of the lathe body 1, a top plate 9 fixedly connected to the top of the uprights 3, an electric push rod 7 installed on the bottom surface of the top plate 9, an installation plate 8 installed on the telescopic end of the electric push rod 7, a protective frame 5 provided at the bottom of the installation plate 8, a grinding device 20 provided on the inner side of the protective frame 5, and an installation frame 16 symmetrically provided on the top surface of the installation plate 8, with a disassembly and assembly assembly provided inside the installation frame 16.
[0028] Specifically, in use, the part to be processed and polished can be placed on the top surface of the lathe body 1. By turning on the electric push rod 7, the electric push rod 7 can drive the mounting plate 8 to rise and fall. The mounting plate 8 can drive the polishing device 20 mounted on the bottom surface to rise and fall. The polishing device 20 of this device is mainly composed of a motor and a polishing disc. The output end of the motor is connected to the polishing disc. By turning on the motor, the polishing disc can be driven to rotate. When the polishing disc comes into contact with the part to be polished, the part can be polished. Since the protective frame 5 is placed on the outside of the polishing device 20, the protective frame 5 can block the debris generated during the polishing process and prevent the sparks generated during the polishing process from spreading outward, thereby protecting the external working environment. The lathe body 1 of this device is actually a CNC lathe. A control panel for controlling the lathe body 1 is provided on one side of the lathe body 1.
[0029] Reference Figure 4 , Figure 5 and Figure 6 The assembly consists of a backing plate 23, a plug rod 15, a telescopic rod 21, and a telescopic spring 22. The telescopic rod 21 is located inside the mounting frame 16. The backing plate 23 is fixedly installed at one end of the telescopic rod 21. The telescopic spring 22 is sleeved on the outside of the telescopic rod 21. The plug rod 15 is fixedly installed on one side of the backing plate 23. A fixing block 24 is fixedly connected to the top surface of the backing plate 23. A lever 17 is fixedly connected to the top surface of the fixing block 24. The top surface of the mounting plate 8 is symmetrically provided with mounting holes 19. The top surface of the protective frame 5 is symmetrically connected with mounting blocks 14, and the mounting blocks 14 are inserted into the mounting holes 19. The surfaces of the two mounting blocks 14 are provided with insertion holes 18.
[0030] Specifically, the size and dimensions of the mounting block 14 correspond to the size and dimensions of the mounting hole 19, and the size and dimensions of the insert rod 15 correspond to the size and dimensions of the insertion hole 18. The two ends of the telescopic spring 22 are connected to the abutment plate 23 and the mounting frame 16 respectively. Thus, when the telescopic rod 21 extends or retracts, it can drive the telescopic spring 22 to extend or retract accordingly. At the same time, the telescopic spring 22 can push the abutment plate 23 through its own reverse force. And when the insert rod 15 is inserted into the insertion hole 18, the mounting block 14 can be fixed in the mounting hole 19. Thus, the protective frame 5 can be fixedly installed on the mounting plate 8.
[0031] Reference Figure 7 The top surface of the lathe body 1 is provided with a telescopic frame 2, and the bottom surface of the telescopic frame 2 is connected with multiple connecting springs 25.
[0032] Specifically, the telescopic frame 2 is positioned directly opposite the protective frame 5. When the protective frame 5 descends, its bottom surface contacts the telescopic frame 2. As the protective frame 5 continues to move downward, it causes the telescopic frame 2 to move downward and compress the connecting spring 25. When the connecting spring 25 is compressed, it can push the telescopic frame 2 through its own reverse force. As the protective frame 5 continues to move downward, it can extend into the interior of the lathe body 1. This ensures that the grinding device 20 inside the protective frame 5 moves downward normally and contacts the part to be ground. When the telescopic frame 2 is pushed back to its original position by the reverse force of the connecting spring 25, the telescopic frame 2 can also push the debris generated during the grinding process to the top surface of the lathe body 1.
[0033] Reference Figure 1 The bottom surface of the top plate 9 is symmetrically provided with guide rods 6, and the bottom end of the guide rods 6 is connected to the mounting plate 8.
[0034] Specifically, the guide rod 6 is telescopic, so that when the telescopic rod 21 drives the mounting plate 8 to rise or fall, the guide rod 6 can extend or retract accordingly, thereby increasing the stability and directional accuracy of the mounting plate 8 during the rise and fall.
[0035] Reference Figure 1 and Figure 2 A fixed plate 4 is fixedly installed on one side of the lathe body 1. A dust suction port 10 is opened on the surface of the fixed plate 4. A dust suction device 11 is fixedly installed on one side of the fixed plate 4 through a fixed bracket. A connecting pipe 12 is connected to one side of the dust suction device 11. A dust collection box 13 is connected to one end of the connecting pipe 12.
[0036] Specifically, the dust suction port 10 is connected to the dust suction device 11. By turning on the dust suction device 11, the dust suction device 11 can suck up the debris remaining on the top surface of the lathe body 1 through the dust suction port 10 and into the dust suction device 11. Then, the dust suction device 11 will transfer the debris to the connecting pipe 12 and finally into the dust collection box 13 through the connecting pipe 12. This makes it convenient for the staff to collect the debris generated during the grinding process.
[0037] Working Principle: When using this device, place it in the designated position, turn on the electric actuator 7. The electric actuator 7 moves the mounting plate 8 downwards, which in turn moves the grinding device 20 on the bottom surface downwards, bringing the grinding device 20 into contact with the part to be ground. Turn on the grinding device 20 to grind the part. Simultaneously, as the mounting plate 8 moves downwards, it also moves the protective frame 5 downwards. The continuous downward movement of the protective frame 5 compresses the telescopic frame 2, allowing the protective frame 5 to extend into the lathe body 1. The protective frame 5 encloses the grinding device 20, preventing debris generated during grinding and avoiding the dispersion of sparks and debris into the external environment, thus maintaining the external working environment. After grinding is complete, start the dust collection device 11 to remove the ground debris. The debris generated during the process is adsorbed through the suction port 10. The adsorbed debris is transferred to the dust collection box 13 through the connecting pipe 12 for centralized treatment by the staff. When the protective frame 5 needs maintenance after prolonged use, the two levers 17 can be moved. The levers 17 drive the abutment plate 23 to move through the fixing block 24. The abutment plate 23 drives the insertion rod 15 to move, disengaging the insertion rod 15 from the insertion hole 18. This releases the fixing state of the mounting block 14, allowing the protective frame 5 to be removed from the mounting plate 8. The removed protective frame 5 can be easily maintained by the staff for subsequent use. When grinding parts, this device can protect the external working environment while also conveniently cleaning up the debris generated after grinding.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
