Description

Technical Field

[0001] This utility model relates to the field of cutting machine protection technology, and more specifically, it relates to a laser cutting machine with a protective device. Background Technology

[0002] With the rapid development of modern manufacturing and the widespread application of laser processing technology, laser cutting machines have become an indispensable core equipment in many industries such as metal processing, mold manufacturing, and advertising production due to their advantages of high precision, high efficiency, and strong applicability. However, the imperfect protection systems of most laser cutting machine products currently on the market have led to many safety hazards in the actual production process.

[0003] Traditional laser cutting machine protective devices generally suffer from problems such as simple structure, incomplete coverage, and poor sealing. They cannot effectively block the high-energy beam reflection, metal spatter, harmful fumes, and noise pollution generated during laser cutting. This not only threatens the personal safety of operators, causing occupational injuries such as eye damage, skin burns, and respiratory diseases, but also causes secondary damage to the surrounding environment and equipment, leading to safety accidents such as fires, pollution, and equipment failures. Utility Model Content

[0006] Preferably, two sets of fixing cylinders are fixedly connected to both sides of the protective cover. Multiple sets of top springs are provided on the inner side wall of the fixing cylinder. The other end of the top spring is connected to a push sleeve. The push sleeve is slidably connected to the inner side wall of the fixing cylinder. The lower end face of the connecting rod abuts against the upper end face of the push sleeve. The fixing cylinder provides a stable installation foundation and precise positioning.

[0007] Preferably, the lower end face of the push plate is provided with a push spring, and the other end of the push spring is provided with a plug rod. The plug rod is slidably connected to the inner side wall of multiple sets of connecting blocks. The plug rod is adapted to the insertion hole. The plug rod and the connecting block are slidably connected to the inner side wall of the fixed cylinder. This elastic locking design realizes the quick and accurate fixing of the protective cover. The push spring provides a constant elastic force for the plug rod, ensuring that the plug rod can be firmly inserted into the insertion hole, forming a reliable mechanical lock.

[0008] Preferably, the inner wall of the fixed cylinder is provided with multiple sets of one-way plates, and the surface of the connecting block is provided with multiple sets of slots that are adapted to the one-way plates. The cooperation between the one-way plates and the slots forms a strong mechanical interlock, which can provide a long-lasting and stable fixing force under high-frequency vibration environment.

[0009] Preferably, a slip ring is slidably connected to the outer wall of the connecting block, and multiple sets of sliding plates are provided on the lower end face of the slip ring. The sliding plates are embedded in the interval groove and slidably connected to the connecting block. The sliding connection between the slip ring and the connecting block provides a stable motion trajectory and an accurate force transmission path. The design of multiple sets of sliding plates ensures the balance and synchronization of the unlocking action and avoids off-center loading and jamming.

[0010] Preferably, the lower outer side wall of the slide plate is provided with a sliding sleeve, and the outer side wall of the sliding sleeve has a groove. The annular design of the groove ensures all-round contact and effective control with the one-way sheet.

[0011] Preferably, the lower end face of the sliding sleeve is provided with multiple sets of vertical rods, and the lower end face of the vertical rods is provided with a push ring. The vertical rods and the push ring constitute an elastically restoring actuator. After the operation is completed, it can automatically return to the initial state under the push of the top spring, so that the one-way sheet disengages from the groove and restores the locking capability.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a laser cutting machine with a protective device, which has the following beneficial effects: This laser cutting machine with a protective device solves the problem of poor protection effect of traditional laser cutting machines through a protective fixing mechanism, improving the safety performance and ease of operation of the equipment. The cutting machine adopts a double-locking protective system, which realizes a reliable connection between the protective cover and the cutting machine body, effectively blocking the reflection of high-energy beams, metal spatter and harmful fumes generated during laser cutting, providing comprehensive safety protection for operators.

[0013] The one-way plate and slot locking mechanism provides reliable locking force, ensuring the protective cover will not open accidentally and reducing operational risks. The automatic compensation design of the top spring and push sleeve continuously provides preload, extending the service life of the locking mechanism. The coordinated work of the slip ring and slide plate forms a convenient one-button unlocking system. Operators only need to push the push plate to safely open the protective cover, without cumbersome operations or additional tools, improving work efficiency. The matching design of the insertion rod and the insertion hole ensures a firm lock on the protective cover, preventing loosening and displacement. The structural design of the groove and the slide sleeve makes the unlocking process smooth and controllable, avoiding potential safety hazards caused by sudden release. The automatic reset function of the vertical rod and the push ring ensures that the mechanism can automatically return to its initial state after use, preparing for the next operation and improving the efficiency of continuous work. This laser cutting machine with protective devices not only solves the safety hazards in existing technologies but also improves the overall safety level and ease of use of laser cutting equipment through mechanical structure design.

The other end of the push spring 28 is provided with a plug rod 29. The plug rod 29 is slidably connected to the inner wall of multiple sets of connecting blocks 22. The plug rod 29 is adapted to the plug hole 14. The plug rod 29 and the connecting block 22 are slidably connected to the inner wall of the fixed cylinder 25. The inner wall of the fixed cylinder 25 is provided with multiple sets of one-way plates 210. The surface of the connecting block 22 is provided with multiple sets of slots 211 adapted to the one-way plates 210. The outer wall of the connecting block 22 is slidably connected with a slip ring 212. The lower end face of the slip ring 212 is provided with multiple sets of sliding plates 213.
