Description

Technical Field

[0001] The present application relates to the technical field of numerically controlled machine tools, and in particular to a safety protection mechanism for machine tools. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool. It is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, and express them in coded numbers. The information carrier is input into the CNC device, and various control signals are sent out by the CNC device after calculation and processing to control the movement of the machine tool. The parts are automatically processed according to the shape and size required by the drawing. When using CNC machine tools, in order to improve the safety of use, a safety protection isolation mechanism is often set outside the machine tool.

[0003] The existing Chinese patent with announcement number CN217045657U discloses a safety protection isolation mechanism for CNC machine tool processing, including a machine tool body, a fixed frame is fixedly installed on one side of the machine tool body, and a slide groove for moving the protection structure is opened at the bottom of the fixed frame, a limit strip is fixedly connected to one side of the top of the machine tool body, and a protection door is movably connected to the outer wall of the limit strip, and a visual window is arranged inside the protection door, a fixed plate is fixedly installed on one side of the machine tool body, and a collection box for collecting iron filings is placed on the top of the fixed plate. In the safety protection isolation mechanism for CNC machine tool processing, the push plate outside the transfer belt pushes the protection door through the block, thereby automatically moving the protection door, and the block on the top of the protection door is removed through the disassembly plate, so that the protection door can be manually moved, thereby facilitating the automatic and manual conversion of the isolation mechanism, and meeting the user's operating requirements, avoiding the situation where the automatic structure cannot be manually adjusted.

[0004] However, the above-mentioned protective device has the following disadvantages: the device wipes the iron filings on the observation window by setting a sponge, but for relatively hard and fine substances such as iron filings, the effect of sponge wiping may be limited, and the iron filings on the observation window cannot be wiped off. In the process of wiping, the inner side of the protective door may even be scratched, and the cleaning efficiency is low.

[0005] Therefore, we propose a safety protection mechanism for machine tools to solve this problem.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

One end of the second pull rope 18 is fixedly connected to the first pull rope 14, and the other end of the second pull rope 18 is fixedly installed with a pull ring 12, which can make the clamping block 17 retract into the fixed tube 16 to release the locked state in the clamping slot 26.

[0030] Reference Figure 6-7 The fixing mechanism includes a connecting tube 20, a connecting column 23, a second elastic member 22, a third pull rope 24 and a second handle 25. The connecting tube 20 is fixedly installed in the fixing frame 11 near the cross block 21. The second elastic member 22 is arranged in the connecting tube 20. A connecting column 23 is arranged on the side of the connecting tube 20 near the cross block 21. The connecting column 23 is elastically connected to the connecting tube 20 through the second elastic member 22. The connecting column 23 passes through the cross block 21, and the connecting column 23 and the cross block 21 are slidably matched. A groove is arranged on the side of the cross groove 19 away from the connecting column 23, and the connecting column 23 is adapted to the groove. A third pull rope 24 is arranged in the connecting tube 20, and the third pull rope 24 passes through the connecting tube 20. One end of the third pull rope 24 is fixedly connected to the connecting column 23, and the other end of the third pull rope 24 is fixedly installed with the second handle 25, which can fix the fixing frame 11 and the cross block 21 to prevent the cross block 21 from vibrating when it moves upward, affecting the collection of iron filings by the collection box 9.

[0031] Reference Figure 2 , Figure 3 and Figure 5 A receiving groove is provided on one side of the top of the placement groove, a baffle 6 is provided in the receiving groove, a fixing groove is provided on the side of the placement groove away from the receiving groove, one side of the baffle 6 is snap-connected with the fixing groove, and the baffle 6 can be stored to prevent the baffle 6 from hindering the magnet 8 and the collection box 9 from moving upward.

[0032] Reference Figure 3 and Figure 5 A slide groove is provided at the top of the storage groove, and a first handle 7 is fixedly installed on one side of the top of the baffle 6. The handle slidably cooperates with the slide groove to move the baffle 6 to one side.

[0033] The implementation principle of the safety protection mechanism of a machine tool in the embodiment of the present application is as follows: when in use, the door body 2 is manually moved to one side, and the magnetic cleaner 5 is close to the door body 2 and the observation window 3. While moving, the iron filings on the door body 2 and the observation window 3 can be adsorbed to the surface of the magnetic cleaner 5 (the magnetic cleaner 5 uses magnetic effect to adsorb iron filings. When the cleaner is close to the iron filing area, its strong magnetic force can quickly adsorb the iron filings on the surface), and the iron filings splashed on the viewing window and the door body 2 are cleaned. After the door body 2 is moved to one side, the first handle 7 can be manually pulled, and the first handle 7 drives the baffle 6 to disengage from the fixed groove and move into the storage groove, and then the hydraulic cylinder 10 is started. The hydraulic cylinder 10 pushes the magnet 8 to move upward, and the magnet 8 drives the fixed frame 11 and the collection box 9 to move upward. When the magnet 8 moves upward along the side of the magnetic cleaner 5 away from the door body 2, an opposite magnetic field or magnetic force will be generated. This opposite magnetic force will interfere with or weaken the original magnetic force on the magnetic cleaner 5. The magnetic force causes the iron filings to fall off the magnetic cleaner 5, so that the iron filings fall into the collection box 9, completing the cleaning work. Then the second handle 25 can be pulled, and the second handle 25 drives the third pull rope 24 to move. The third pull rope 24 drives the connecting column 23 to enter the connecting tube 20, and then the fixed frame 11 is slid upward to make the cross block 21 slide out of the cross groove 19 to process the iron filings in the collection box 9. Then the cross block 21 is placed in the cross groove 19 and slides downward to the bottom. The connecting column 23 enters the groove with the force of the second elastic member 22 to fix the fixing frame 11. When the magnetic cleaner 5 needs to be disassembled, the pull ring 12 can be pulled, and the pull ring 12 pulls the second pull rope 18. The second pull rope 18 drives the first pull rope 14. The first pull rope 14 enters the fixed tube 16 with two card blocks 17, so that the locking mechanism disengages from the card slot 26, and the lock on the mounting seat 4 is released, so that the magnetic cleaner 5 is removed from the inside of the machine tool body 1 for replacement.
