Description

Technical Field

[0001] This utility model relates to the field of sheet metal cutting technology, and in particular to a sheet metal cutting device. Background Technology

[0002] Sheet cutting refers to the process of cutting sheet materials into the required size and shape using various cutting techniques. This process is an indispensable part of modern manufacturing and construction industries, and it is of great significance for improving material utilization, reducing production costs, and meeting specific design requirements.

[0003] Currently, sheet metal cutting mainly uses laser cutting machines. When using a laser cutting machine, the sheet metal to be cut is placed on a work stand. After the cutting head is operated for initial edge positioning, the cutting begins. The laser beam is guided and focused onto the material surface through the optical system inside the cutting head. As the cutting head moves, the sheet metal is cut.

[0004] Existing laser cutting machines require regular inspection and maintenance of the optical system inside the cutting head, such as reflectors and focusing lenses, after use. This necessitates disassembling the cutting head from the fiber rod inside the machine housing. However, the existing assembly method for the cutting head is cumbersome and not conducive to portable disassembly, making it inconvenient to use. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Example 1

[0031] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This is the first embodiment of the present invention. This embodiment provides a plate cutting device, including a housing 1. A work frame 2 is arranged inside the housing 1. An optical fiber rod 5 is movably arranged inside the housing 1. A cutting head 3 is arranged below the optical fiber rod 5. A connecting component 4 is arranged between the optical fiber rod 5 and the cutting head 3. A locking component 6 is arranged inside the housing 1. The connecting component 4 includes an insertion rod 401 fixedly connected to the bottom end of the optical fiber rod 5. A fixing block 404 is fixedly connected to the top end of the cutting head 3. A locking block 403 is slidably arranged on the outer surface of the fixing block 404. A pressing cylinder 405 is threadedly connected to the outer surface of the top of the cutting head 3.

[0032] Specifically, the top of the cutting head 3 has an insertion hole that mates with the insertion rod 401. There are four fixing blocks 404 in total. A locking block 403 is slidably disposed between two adjacent fixing blocks 404. The outer surface of the locking block 403 has a limit protrusion. The outer surface of the fixing block 404 has a limit groove that mates with the limit protrusion. A snap-fit ​​block 406 is fixedly connected to the inner side of the locking block 403. The outer surface of the snap-fit ​​block 406 has a bevel. The outer surface of the insertion rod 401 has a snap-fit ​​groove. The outer surface of block 406 has a beveled groove that matches the beveled surface. The outer surface of locking block 403 is fixedly connected to abutment block 407. The outer surface of abutment block 407 is provided with a beveled surface. The inner side of the top of extrusion cylinder 405 is provided with a beveled surface that matches the beveled surface of the outer surface of abutment block 407. The outer surface of fiber rod 5 is threadedly connected to sealing cylinder 402. The upper surface of abutment block 407 has a slot. The inner side of sealing cylinder 402 is fixedly connected to insertion tube 408 that matches the slot on the upper surface of abutment block 407.

[0033] Furthermore, rotating the sealing cylinder 402 causes the sealing cylinder 402 and the insertion tube 408 to move upward, thereby exposing the locking block 403. Then, rotating the squeezing cylinder 405 causes the squeezing cylinder 405 to separate from the abutment block 407. After the squeezing cylinder 405 separates from the abutment block 407, the fiber optic rod 5 is pulled upward, thereby causing the snap-fit ​​block 406 to move outward through the inclined groove on the outer surface of the insertion rod 401, thereby pulling out the insertion rod 401 and solidly separating the cutting head 3 from the fiber optic rod 5, realizing the disassembly of the cutting head 3 for easy maintenance. By rotating the sealing cylinder 402, the sealing cylinder 402 is lowered, achieving abutment against the outer surface of the squeezing cylinder 405, thereby playing a sealing role to prevent dust from entering the interior of the cutting head 3 through the connection part. Furthermore, through the cooperation of the insertion tube 408 and the slot on the upper surface of the abutment block 407, the locking block 403 is further locked.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 and Figure 7 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The locking component 6 includes a connecting block 608 movably disposed at the top of the inner cavity of the chassis 1. A plug frame 604 is fixedly connected to the side of the connecting block 608 near the cutting head 3. A fixing plate 601 is provided on the outer surface of the cutting head 3. Two rotating plates 602 are hinged to the outer surface of the connecting block 608. A stop block 603 is fixedly connected to the outer surface of the rotating plate 602. A movable block 606 is slidably disposed on the outer surface of the connecting block 608. A plug plate 605 is fixedly connected to the lower surface of the movable block 606.

[0036] Specifically, the outer surface of the connecting block 608 is provided with a sliding groove that cooperates with the movable block 606, a spring 607 is fixedly connected between the movable block 606 and the connecting block 608, the upper surface of the stop block 603 is provided with a slot that cooperates with the insert plate 605, and the interior of the insertion frame 604 is provided with an insertion groove that cooperates with the fixed plate 601.

[0037] Furthermore, the movable block 606 slides upward, thereby causing the insert plate 605 to separate from the stop block 603, unlocking the rotating plate 602. After the rotating plate 602 is rotated to the outside, the stop block 603 is released from the upper surface of the insertion frame 604, allowing the cutting head 3 to be pulled out from inside the insertion frame 604. After the cutting head 3 is pulled out, when the stop block 603 locks the fixing plate 601 inserted into the insertion frame 604, the movable block 606 moves downward under the action of the spring 607, thereby causing the insert plate 605 to insert into the slot on the upper surface of the stop block 603, thus locking the stop block 603 and preventing the rotating plate 602 from rotating.

[0038] Working principle: When the cutting head 3 needs to be replaced, slide the movable block 606 upward, thereby causing the insertion plate 605 to separate from the stop block 603, unlocking the rotating plate 602. After rotating the rotating plate 602 to the outside, it causes the stop block 603 to release the seal on the upper surface of the insertion frame 604, allowing the cutting head 3 to be pulled out from inside the insertion frame 604. After the cutting head 3 is pulled out, rotate the sealing cylinder 402, causing the sealing cylinder 402 and the insertion tube 408 to move upward, thereby exposing the locking block 403. Then rotate the squeezing cylinder 405, causing the squeezing cylinder 405 to separate from the abutment block 407. After the squeezing cylinder 405 separates from the abutment block 407, pull the fiber rod 5 upward, thereby causing the locking block 406 to move outward through the inclined groove on the outer surface of the insertion rod 401, thereby pulling out the insertion rod 401, realizing the separation of the cutting head 3 and the fiber rod. 5. To facilitate the disassembly and maintenance of the cutting head 3, after maintenance, the cutting head 3 and the fiber rod 5 are connected using the same steps. After the connection is completed, the sealing cylinder 402 is rotated to lower the sealing cylinder 402, which abuts against the outer surface of the extrusion cylinder 405, thereby sealing and preventing dust from entering the cutting head 3 through the connection. Furthermore, the locking block 403 is further locked by the cooperation of the insertion tube 408 and the slot on the upper surface of the abutment block 407. When the stop block 603 locks the fixing plate 601 inserted into the insertion frame 604, the moving block 606 is moved downward by the action of the spring 607, thereby driving the insertion plate 605 to insert into the slot on the upper surface of the stop block 603, thereby locking the stop block 603 and preventing the rotating plate 602 from rotating, thus completing the maintenance of the cutting head 3.
