[0003] At present, many laser cutting devices for processing rail transit parts are already relatively mature, but few of them pay attention to the problem of cleaning the residues cut off. This has caused the problem of manual cleaning of laser cutting residues by the staff during actual operation. After the machine works for a long time, a large amount of accumulated materials are formed, which causes great inconvenience to personnel operation and has a certain degree of danger. Summary of the Utility Model

[0004] The utility model belongs to the technical field of laser cutting, and can facilitate the machine operator to clean the residues remaining after laser cutting, without the need for manual extraction of residues, saving time and effort and improving the safety of personnel operating the machine.

[0005] The technical solution adopted by the utility model is specifically as follows:

[0006] A laser cutting device for processing rail transit parts includes a main body. A Y rail is fixedly installed on the main body. A sliding end is slidably sleeved outside the Y rail. A fixator is fixedly installed on the sliding end. An X rail is clamped between adjacent fixators. A control host is slidably sleeved on the X rail. A laser cutter is fixedly installed at the front end of the control host; several sliding rails are rotatably clamped inside the main body. A chute is slidably connected to the inner side of the lower part of the main body. A collection bin is installed inside the chute. An elastic contraction device is installed at the rear end of the chute. An electric lifting device is arranged at the lower end of the collection bin.

[0007] In a preferred embodiment, the sliding end reciprocates around the Y track, and the control host reciprocates around the X track.

[0008] In a preferred embodiment, there are semi-circular bumps on the Y track, and the semi-circular bumps are integrally formed in the middle of the Y track.

[0009] In a preferred embodiment, the elastic contraction device includes a fixed rod, the fixed rod is fixedly clamped inside the main body, fixed blocks are fixedly sleeved at both ends of the fixed rod, and the fixed blocks are as close as possible to both ends of the fixed rod. A rotating shaft is installed on the fixed block, a sliding rod is hinged to the rotating shaft, one end of the sliding rod away from the fixed rod is connected with a sliding block, the sliding block is placed in a cylindrical accommodating space at the rear end of the chute, and a spring is arranged on the side of the sliding block close to the edge and inside the accommodating space. A partition block is arranged between adjacent sliding blocks.

[0010] In a preferred embodiment, the electric lifting device includes electric push rods. One end of each of the two electric push rods is fixedly hinged with a sliding shaft, and the other end of the sliding shaft is hinged with a fixed shaft, and the fixed shaft is hinged at the bottom position of the collection bin.

[0011] In a preferred embodiment, both ends of the chute are set as hook-shaped structures, and the collection bin can rotate around the rotating shaft at the edge of the chute.

[0012] The technical effects achieved by the present utility model are as follows:

[0013] After the rail transit component plate is placed on the slide rail platform by the operator, the laser cutting device operates the sliding end so that the sliding end can move on the Y track. At the same time, the laser cutting device operates the control host so that the control host can move on the Y track, thereby enabling the laser cutter to move in both the X and Y directions; after laser cutting is completed, the residue remains on the collection bin. By manually pulling the collection bin, the elastic contraction device linked to the collection bin is opened, and the accommodating space inside the collection bin moves with the pulled collection bin, causing the internal spring to drive the sliding block to contract. The sliding rod hinged to the sliding block also moves accordingly, and the sliding rod hinged to the rotating shaft slowly rotates outwards, causing the collection bin to move outwards relative to the fixed rod. Thus, the collection bin is manually pulled out; then the operator starts the electric push rod. The electric push rod moves outwards relative to the cylinder, driving the sliding shaft to push outwards, and the fixed shaft hinged to the electric push rod and the collection bin is pushed upwards, causing the collection bin to slowly lift upwards, and the residue in the collection bin slides down unobstructed along the inclined angle.

[0014] The utility model belongs to the technical field of laser cutting, which can facilitate the machine operator to clean the residue left by laser cutting, without manual extraction of the residue, saving time and effort and improving the safety of personnel operating the machine.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the above objects, features and advantages of the utility model more obvious and understandable, the following detailed description of the specific embodiments of the utility model will be given with reference to the drawings in the specification.

[0023] In the following description, many specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed below.

[0024] Such as Figure 1As shown in the figure, a laser cutting device for processing rail transit parts includes a main body 1. A Y-rail 2 is fixedly installed on the main body 1. A sliding end 4 is slidably sleeved outside the Y-rail 2. A fixture 5 is fixedly installed on the sliding end 4. An X-rail 6 is clamped between adjacent fixtures 5. A control host 7 is slidably sleeved on the X-rail 6. A laser cutter 8 is fixedly installed at the front end of the control host 7. Several sliding rails 3 (rotatable light rollers) are clamped inside the main body 1. Adjacent main bodies 1 are connected by the sliding rails 3. A chute 9 is slidably connected to the lower part near the inner side of the main body 1. A collection bin 10 is installed inside the chute 9. An elastic contraction device 12 is installed at the rear end of the chute 9. An electric lifting device is arranged at the lower end of the collection bin 10.

[0025] Specifically, the laser cutting device operates the sliding end 4 so that the sliding end 4 can move on the Y-rail 2. At the same time, the laser cutting device operates the control host 7 so that the control host 7 can move on the Y-rail 2, thereby enabling the laser cutter 8 to move in both the X and Y directions. After laser cutting is completed, the residue remains on the collection bin 10. By manually pulling the collection bin 10, the elastic contraction device 12 linked to the collection bin 10 is opened. The accommodation space inside the collection bin 10 moves with the pulled collection bin 10, causing the internal spring 124 to drive the sliding block 123 to contract. The sliding rod 122 hinged on the sliding block 123 also moves accordingly. The sliding rod 122 hinged on the rotating shaft 121 slowly rotates outward, causing the collection bin 10 to move outward relative to the fixed rod 120. Subsequently, the operator starts the electric push rod 14. The electric push rod 14 moves outward relative to the cylinder 13. The electric push rod 14 drives the sliding shaft 15 to push outward. The fixed shaft 16 hinged on the electric push rod 14 and the collection bin 10 is pushed upward, causing the collection bin 10 to slowly lift upward. The residue inside the collection bin 10 slides down without obstruction along the inclined angle.

[0026] As Figure 2 shown, the sliding end 4 makes a reciprocating motion around the Y-rail 2, and the control host 7 makes a reciprocating motion around the X-rail 6.

[0027] Specifically, the sliding end 4 and the control host 7 can move around the Y-rail 2 and the X-rail 6 respectively, enabling the laser cutter 8 to work in the entire horizontal plane, thus solving the problem of working in both the X and Y directions simultaneously. The movement of the sliding end 4 and the control host 7 can be driven by a walking motor. This method is very mature in the prior art and belongs to the existing mature technology. Here, it is actually an X-Y axis electric guide rail, so the specific structure will not be described in detail here.

[0028] As Figure 5 shown, there is a semi-circular convex block 201 on the Y-rail 2. The semi-circular convex block 201 is integrally formed in the middle of the Y-rail 2.

[0029] Specifically, the semi-circular bumps 201 are symmetrically arranged around the Y-track 2, and the semi-circular bumps 201 located in the middle can better lock the sliding end 4 firmly on the Y-track 2. The size of the semi-circular bumps 201 needs to be appropriate enough. If it is too small, it is not easy to make the sliding end 4 stuck on the Y-track 2. If the bumps are too large, the sliding space of the sliding end 4 will be limited, and the sliding friction will increase, which is not conducive to sliding.

[0030] As Figure 5 As shown, the elastic contraction device 12 includes a fixed rod 120, the fixed rod 120 is fixedly clamped inside the main body 1, both ends of the fixed rod 120 are fixedly sleeved with fixed blocks 126, and the fixed blocks 126 are as close as possible to both ends of the fixed rod 120. A rotating shaft 121 is installed on the fixed block 126, the rotating shaft 121 is hinged with a sliding rod 122, one end of the sliding rod 122 away from the fixed rod 120 is connected with a sliding block 123, the sliding block 123 is placed in the cylindrical accommodation space at the rear end of the chute 9, and a spring 124 is arranged on one side of the sliding block 123 close to the edge and inside the accommodation space. A partition block 125 is arranged between adjacent sliding blocks 123.

[0031] Specifically, when the collection bin 10 is pulled out, the accommodation space at the rear end of the collection bin 10 will cause the spring 124 to contract, and the sliding rod 122 will move slowly outwards. The rotating shaft 121 is fixed on the fixed block 126 and rotates, so that when the collection bin 10 is finally pulled out, the sliding rod 122 is almost perpendicular to the fixed rod 120; when the collection bin 10 is released, since the spring 124 in the accommodation space of the collection bin 10 is in a compressed state, without external force, the spring 124 will drive the sliding rod 122 to move and expand, making the collection bin 10 rebound; it should be noted that the natural length of the spring 124 is limited. When the collection bin 10 is completely inside the chute 9, the spring 124 is in a natural state. When the collection bin 10 is completely pulled out, the spring 124 is in a compressed state; the radius of the accommodation space is slightly larger than the radius of the spring 124, the shape of the accommodation space is a columnar long strip shape, and the length of the accommodation space is greater than the natural length of two springs 124; a partition block 125 is arranged in the middle, so that the two springs 124 move independently of each other without interference.

[0032] As Figure 4 As shown, the electric lifting device includes electric push rods 14. One end of each of the two electric push rods 14 is fixedly hinged with a sliding shaft 15, and the other end of the sliding shaft 15 is hinged with a fixed shaft 16. The fixed shaft 16 is hinged at the bottom of the collection bin 10.

[0033] Specifically, the electric push rod 14 moves outward relative to the cylinder 13. The electric push rod 14 drives the sliding shaft 15 to push outward. The fixed shaft 16 hinged to the electric push rod 14 and the collection bin 10 is pushed upward, causing the collection bin 10 to slowly lift upward. The residue in the collection bin 10 slides down unobstructed along the inclined angle. The electric push rod 14 is arranged inside the cylinder 13 and can extend and retract toward one end of the cylinder 13 away from the rear end of the chute 9. The fixed shaft 16 is hinged to one end of the sliding shaft 15, and the other end of the fixed shaft 16 is hinged to the middle position at the bottom of the collection bin 10. When the collection bin 10 is fully raised, the raised angle forms a 45-degree angle with the horizontal plane. At this time, the electric push rod 14 is in a shortened state. When the collection bin 10 is fully retracted into the chute 9, the electric push rod 14 is in the maximum extended state. The technology of the electric push rod 14 is currently an existing and mature technology, and its specific working principle and operation method will not be elaborated here.

[0034] As Figure 4 shown, both ends of the chute 9 are provided with a hook-shaped structure 17, and the collection bin 10 can rotate around the rotating shaft 18 at the edge of the chute 9.

[0035] Specifically, the hook-shaped structure 17 can be completely clamped on both sides of the adjacent main body 1, making the chute 9 convenient to disassemble. The front end of the chute 9 is provided with a rotating shaft 18, enabling the collection bin 10 to flexibly rotate around the rotating shaft 18 on the chute 9. Moreover, the front end of the chute 9 has a 45-degree slope foot, which can make the slope foot correspond to the inclined angle of the collection bin 10 after the collection bin 10 is fully raised.

[0036] The working principle of the present utility model is as follows: After the rail transit component plate is placed on the sliding rail 3 platform by the operator, the laser cutting device operates the sliding end 4, enabling the sliding end 4 to move on the Y rail 2. At the same time, the laser cutting device operates the control host 7, enabling the control host 7 to move on the Y rail 2, so that the laser cutter 8 can move in both the X and Y directions simultaneously. After laser cutting is completed, the residue remains on the collection bin 10. By manually pulling the collection bin 10, the elastic contraction device 12 linked to the collection bin 10 is opened. The accommodation space inside the collection bin 10 moves with the pulled collection bin 10, causing the internal spring 124 to drive the sliding block 123 to contract. The sliding rod 122 hinged to the sliding block 123 also moves accordingly. The sliding rod 122 hinged to the rotating shaft 121 slowly rotates outward, causing the collection bin 10 to move outward relative to the fixed rod 120. Subsequently, the operator starts the electric push rod 14. The electric push rod 14 moves outward relative to the cylinder 13. The electric push rod 14 drives the sliding shaft 15 to push outward. The fixed shaft 16 hinged to the electric push rod 14 and the collection bin 10 is pushed upward, causing the collection bin 10 to slowly lift upward. The residue in the collection bin 10 slides down unobstructed along the inclined angle.

[0037] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented by conventional means in the art without special description and limitation.
