Description

Technical Field

[0001] This utility model belongs to the field of laser cutting, and in particular relates to a stable laser cutting head. Background Technology

[0002] With the rapid development of modern manufacturing, laser cutting technology has been widely used in metal processing, mold making, aerospace, and automotive industries due to its advantages such as high precision, high efficiency, and low heat-affected zone. As the core component of a laser cutting machine, the performance of the laser cutting head directly determines the cutting quality.

[0003] However, existing laser cutting heads still have certain drawbacks. For example, they are usually connected and fixed with multiple bolts, but these bolts may loosen during long-term use, which will affect the stability of the laser cutting head. Secondly, when installing the laser cutting head, one hand needs to hold the laser cutting head while the other hand uses a tool to screw multiple bolts into the corresponding threaded holes in sequence, which is quite inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a stable laser cutting head to solve the problem of instability in traditional laser cutting heads when connected by bolts.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a stable laser cutting head, comprising a laser cutting head body, a fixing plate disposed on the rear surface of the laser cutting head body, four first threaded holes disposed on the front surface of the fixing plate, fixing bolts threaded to the inner surface of the first threaded holes, two connecting plates threaded to the outer surface of the fixing bolts, two snap-fit ​​boxes fixedly connected to the side surface of the laser cutting head body, a slide rod slidably connected to the inner surface of the snap-fit ​​box, a pressure block fixedly connected to the outer surface of the slide rod, a U-shaped inclined plate fixedly connected to the end away from the pressure block, a guide rod fixedly connected to the inner surface of the snap-fit ​​box, a spring disposed on the outer surface of the guide rod, an L-shaped snap-fit ​​slidably connected to the outer surface of the guide rod, and an inclined block fixedly connected to the outer surface of the L-shaped snap-fit.

[0007] Preferably, the front surface of the fixing plate is provided with a slot that matches the L-shaped buckle, which facilitates the installation of the laser cutting head body.

[0008] Preferably, the inner surface of the slot is provided with a slot that matches the L-shaped buckle, which facilitates the initial fixation of the laser cutting head body.

[0009] Preferably, the outer surface of the connecting plate has a through hole to facilitate the movement of the L-shaped buckle.

[0010] Preferably, the outer surface of the connecting plate is provided with a second threaded hole, the inner surface of the second threaded hole is adapted to the fixing bolt, and the position of the second threaded hole corresponds to the first threaded hole, so as to facilitate the screwing in of the fixing bolt.

[0011] Preferably, the side surface of the laser cutting head body is fixedly connected to the connecting plate, and the front surface of the connecting plate is in contact with the snap-fit ​​box.

[0012] Preferably, the outer surface of the U-shaped inclined frame is slidably connected to the inclined block, and the outer surface of the U-shaped inclined frame is slidably connected to the buckle box.

[0013] Preferably, both ends of the spring are in contact with the L-shaped buckle, and the outer surface of the L-shaped buckle is slidably connected to the buckle box.

[0014] This utility model has the following beneficial effects:

[0015] This utility model, by setting up a buckle box, slide bar, pressure block, U-shaped inclined plate frame, guide rod, spring, L-shaped buckle and inclined plate, etc., can form a double fixing mechanism with fixing bolts, thereby effectively preventing the laser cutting head body from loosening or shifting due to vibration or impact during the cutting process, thus improving the stability and reliability of the connection. Moreover, when installing the laser cutting head body, the laser cutting head body can be initially fixed in a predetermined position on the fixing plate, which facilitates the subsequent screwing in of multiple fixing bolts.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0025] like Figures 1-4 As shown, this utility model is a stable laser cutting head, including a laser cutting head body 1, a fixing plate 2 disposed on the rear surface of the laser cutting head body 1, four first threaded holes 3 disposed on the front surface of the fixing plate 2, fixing bolts 4 threadedly connected to the inner surface of the first threaded holes 3, two connecting plates 5 threadedly connected to the outer surface of the fixing bolts 4, two snap-fit ​​boxes 6 fixedly connected to the side surface of the laser cutting head body 1, a slide rod 7 slidably connected to the inner surface of the snap-fit ​​box 6, a pressure block 8 fixedly connected to the outer surface of the slide rod 7, a U-shaped inclined frame 9 fixedly connected to the end away from the pressure block 8, a guide rod 10 fixedly connected to the inner surface of the snap-fit ​​box 6, a spring 11 disposed on the outer surface of the guide rod 10, an L-shaped snap 12 slidably connected to the outer surface of the guide rod 10, and a spring 11 fixedly connected to the outer surface of the L-shaped snap 12. The inclined block 13 on the surface, the front surface of the fixing plate 2 is provided with a slot 14 that matches the L-shaped buckle 12, the inner surface of the slot 14 is provided with a groove 15 that matches the L-shaped buckle 12, the outer surface of the connecting plate 5 is provided with a through hole 16, the outer surface of the connecting plate 5 is provided with a second threaded hole 17, the inner surface of the second threaded hole 17 matches the fixing bolt 4, the position of the second threaded hole 17 corresponds to the first threaded hole 3, the side surface of the laser cutting head body 1 is fixedly connected to the connecting plate 5, the front surface of the connecting plate 5 is in contact with the buckle box 6, the outer surface of the U-shaped inclined frame 9 is slidably connected to the inclined block 13, the outer surface of the U-shaped inclined frame 9 is slidably connected to the buckle box 6, both ends of the spring 11 are in contact with the L-shaped buckle 12, the outer surface of the L-shaped buckle 12 is slidably connected to the buckle box 6.

[0026] In this embodiment, when the laser cutting head body 1 needs to be installed, simply press the pressure block 8 to drive the slide rod 7 to slide the U-shaped inclined plate 9 along the inclined surface on the inclined block 13. This will cause the two corresponding L-shaped buckles 12 to move towards each other along the guide rod 10 and compress the spring 11. Then, the compressed L-shaped buckles 12 are aligned with the slot 14 and inserted. When the L-shaped buckles 12 correspond to the slot 15, the pressure block 8 is released. Under the action of the spring 11's rebound force, the L-shaped buckles 12 will automatically insert into the slot 15, thereby completing the initial positioning and fixing of the laser cutting head body 1. At this time, the second threaded hole 17 on the connecting plate 5 overlaps with the first threaded hole 3, so that multiple fixing bolts 4 can be screwed in sequentially. The limiting of the L-shaped buckles 12, the slot 14, and the slot 15 can cooperate with the screwing in of the fixing bolts 4 to form a double fixing structure, thereby effectively improving the stability of the laser cutting head body 1 during installation.
