The existing laser cutting machine torch anti-collision mechanism has a relatively simple structure and insufficient protection, failing to effectively protect the cutting head. Moreover, due to the complex and varied causes of impacts on the cutting head, damage from impacts is inevitable, ultimately affecting the use of the cutting machine. Summary of the Invention

[0024] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses an anti-collision mechanism for the cutting head of a laser cutting machine torch. (Refer to...) Figure 1 A laser cutting machine torch cutting head anti-collision mechanism includes a cutting head 1 located at the bottom, used for cutting external workpieces. A horizontal collision protection component 2 is disposed above the cutting head 1, buffering horizontal collisions to the cutting head 1. The horizontal collision protection component 2 includes a first horizontal collision protection part 21, which protects and buffers minor collisions to the cutting head 1. A second horizontal collision protection part 22 is disposed at the top of the first horizontal protection part, protecting and buffering larger horizontal collisions to the cutting head 1. A vertical collision protection component 3 is also vertically disposed above the cutting head 1, protecting and buffering vertical collisions to the cutting head 1.

[0028] Reference Figure 1 , Figure 2 A clamping assembly 4 is also provided at the top of the cutting head 1, which clamps the cutting heads 1 of different specifications. The clamping assembly 4 includes a fastening box 41, which is fixedly connected to the bottom end of the second horizontal collision protection part 22. The fastening box 41 is a hollow rectangular structure, and a through hole is vertically opened at the bottom end of the fastening box 41, which connects the interior of the fastening box 41 with the outside. The cutting head 1 enters the interior of the fastening box 41 through the through hole.

[0029] The cutting head 1 has clamping parts 42 on both sides inside the fastening box 41. Each clamping part 42 includes a rotating motor 421 fixed inside the fastening box 41. The motor shaft of the rotating motor 421 is vertically arranged, and a rotating rod 422 is coaxially fixedly connected to the motor shaft. A second bevel gear 423 is coaxially fixedly connected to the top of the rotating rod 422. A threaded rod 424 is horizontally arranged on the side of the cutting head 1 near the rotating rod 422. The threaded rod 424 is movably connected to both sides of the inner cavity of the fastening box 41 through bearings. A first bevel gear 425 is coaxially fixedly connected to the threaded rod 424 relative to the position of the second bevel gear 423. The first bevel gear 425 meshes with the second bevel gear 423.

[0030] The threaded rod 424 is threaded to a fastening plate 426 at one end near the cutting head 1. The fastening plate 426 is threaded to the surface of the threaded rod 424 through a threaded sleeve, and the fastening plate 426 abuts and fixes the side wall of the cutting head 1.

[0031] The rotating motor 421 drives the rotating rod 422 to rotate, which in turn drives the second bevel gear 423 to rotate. The second bevel gear 423 drives the first bevel gear 425, which meshes with it, to rotate. This causes the first bevel gear 425 to drive the threaded rod 424 to rotate along the axial direction. The threaded rod 424 drives the fastening plate 426, which is threaded to it, to move in the horizontal direction, so that the distance between the fastening plates 426 on both sides of the cutting head 1 can be adjusted. The two fastening plates 426 can fix the cutting head 1 of different diameters.

[0032] Reference Figure 3 , Figure 4 The second horizontal collision protection part 22 includes a protective shell 221, which is a hollow rectangular structure. An avoidance hole is provided at the bottom end of the protective shell 221 relative to the position of the cutting head 1, and the avoidance hole connects the interior of the protective shell 221 with the outside.

[0033] A crash shield 222 is fixedly connected to the top of the fastening box 41. The crash shield 222 is a rectangular shell, and the crash shield 222 extends into the interior of the protective shell 221 through the clearance hole. The width of the clearance hole is greater than the width of the crash shield 222, so that there is a gap on both sides of the crash shield 222 located at the clearance hole.

[0034] Inside the protective shell 221, dampers 223 are respectively provided on both sides of the anti-collision shell 222. The two opposing dampers 223 are arranged along the width direction of the protective shell 221, and one end of the damper 223 is fixedly connected to the inner wall of the protective shell 221, and the other end of the damper 223 is fixedly connected to the outer wall of the anti-collision shell 222.

[0035] Two dampers 223 are respectively installed on both sides of the anti-collision shell 222. The two sets of dampers 223 are arranged opposite each other, so that when the external force hits the protective shell 221, the anti-collision shell 222 transmits the force to the damper 223, and the damper 223 protects the cutting head 1 by its own elastic rebound.

[0036] Reference Figure 3 , Figure 4The first horizontal collision protection part 21 includes baffles 211 located on both sides of the fastening box 41. The two opposing baffles 211 are arranged along the width direction and are opposite to the side wall of the fastening box 41. A cavity is provided on the bottom wall of the protective shell 221. A first spring 212 is horizontally arranged inside the cavity. One end of the first spring 212 is fixedly connected to the side wall of the protective shell 221, and the other end of the first spring 212 is fixedly connected to a right-angle plate 213. The right-angle plate 213 has an "L" shaped structure and includes a vertically arranged vertical plate 2131 and a horizontally arranged horizontal plate 2132 at the bottom end of the vertical plate 2131. The vertical plate 2131 and the horizontal plate 2132 are fixedly connected. An opening is provided on the bottom wall of the protective shell 221 relative to the vertical plate 2131. The vertical plate 2131 of the right-angle plate 213 extends from the opening, and the horizontal plate 2132 of the right-angle plate 213 is located on the outside of the protective shell 221. The width of the opening along the width direction is greater than the width of the right-angle plate 213, so that the opening is spaced apart from the vertical plate 2131 along the width direction. The end of the horizontal plate 2132 away from the vertical plate 2131 is fixedly connected to the baffle 211. So when the cutting head 1 is impacted, when it is subjected to forces from the left and right sides, the baffle 211 moves first, thereby driving the right-angle plate 213 to move. The right-angle plate 213 compresses the first spring 212, and the first spring 212 uses its own elasticity to rebound and protect the cutting head 1.

[0037] Reference Figure 1 , Figure 3 The vertical collision protection component 3 includes a rebound shell 31 located at the top of the protective shell 221. The rebound shell 31 is fixedly connected to the protective shell 221, and the rebound shell 31 is disposed opposite to the anti-collision shell 222. An elastic column 32 is vertically disposed on the top wall of the protective shell 221 at a position opposite to the inside of the rebound shell 31. The bottom end of the elastic column 32 extends into the interior of the protective shell 221 and is fixedly connected to the top wall of the anti-collision shell 222. The top end of the elastic column 32 extends into the interior of the rebound shell 31. A connecting plate 33 is horizontally disposed at the top end of the elastic column 32. The connecting plate 33 is fixedly connected to the elastic column 32. A second spring 34 is vertically disposed at the top end of the connecting plate 33. The top end of the second spring 34 abuts against the top end of the inner side wall of the rebound shell 31, and the bottom end of the second spring 34 abuts against the connecting plate 33.

[0038] When subjected to an impact force from below the cutting head 1, the fastening box 41 will move, and the fastening box 41 will move the elastic column 32 and the anti-collision shell 222. The elastic column 32 and the anti-collision shell 222 will compress the second spring 34, and the second spring 34 will use its own elastic rebound to protect the cutting head 1.

[0039] The implementation principle of this application embodiment is as follows: When different models of cutting heads 1 need to be installed, the required model of cutting head 1 is first installed in the inner cavity of the fastening box 41. Then, the rotating motor 421 is turned on. The rotating motor 421 drives the rotating rod 422 to rotate. The rotating rod 422 drives the second bevel gear 423 to rotate. The second bevel gear 423 drives the first bevel gear 425 to rotate. The first bevel gear 425 drives the threaded rod 424 to rotate. The threaded rod 424 drives the fastening plate 426 to move. The fastening plate 426 clamps the cutting head 1 a second time, improving the anti-collision performance of the cutting head 1.

[0040] When the cutting head 1 is impacted, when it is subjected to forces from the left and right sides, the baffle 211 is moved first, which in turn drives the right-angle plate 213 to move. The right-angle plate 213 compresses the first spring 212, and the first spring 212 uses its own elasticity to rebound and protect the cutting head 1.

[0041] When the impact force is large, it will hit the anti-collision shell 222. The anti-collision shell 222 will transmit the force to the damper 223. The damper 223 will protect the cutting head 1 by its own elastic rebound.

[0042] When subjected to an impact force from below the cutting head 1, the fastening box 41 will move, and the fastening box 41 will move the elastic column 32 and the anti-collision shell 222. The elastic column 32 and the anti-collision shell 222 will compress the second spring 34, and the second spring 34 will use its own elastic rebound to protect the cutting head 1.
