Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a laser cutting machine capable of preventing splashing. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam is irradiated to the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and finally forming a cut in the material, thereby achieving the purpose of cutting.

[0003] When the laser cutting machine is cutting steel plates, the high-power density laser beam will generate a large amount of sparks when it contacts the steel plates. Sparks will fly during the cutting process. The flying sparks will not only affect the workers' observation of the cutting of the steel plates, but may also accidentally injure the workers. Utility Model Content

[0004] The purpose of the utility model is to provide a splash-proof laser cutting machine to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a splash-proof laser cutting machine, comprising a gantry 1, a linear slide 2 is fixedly installed on the top of the gantry 1, a laser emitter 4 is arranged on the linear slide 2, a laser emitter 4 is slidably connected to a laser emitter head 5 at the bottom of the laser emitter 4, a cylinder 6 is fixedly installed on the side wall of the laser emitter 4, a piston end of the cylinder 6 is fixedly installed on the outer wall of the laser emitter head 5, a storage table 3 is fixedly installed on the bottom of the gantry 1, and a protective mechanism 7 for preventing sparks from splashing is arranged on the laser emitter head 5. By setting the protective mechanism 7, it can be prevented that sparks splashing during cutting of steel plates may accidentally injure workers.

[0023] Specifically, the protection mechanism 7 includes a sleeve 71, a protective cover 72, a spring 73, and a steel ball 74; the sleeve 71 is fixedly mounted on the bottom of the laser emitting head 5, and the protective cover 72 is slidably connected to the inner wall of the sleeve 71. The protective cover 72 and the sleeve 71 can be used to cover the cutting position of the laser emitting head 5 on the steel plate to prevent sparks from flying when the steel plate is cut and accidentally injuring the staff. The bottom of the protective cover 72 is rollingly connected with multiple groups of steel balls 74, and the steel balls 74 can reduce the friction between the protective cover 72 and the steel plate. One end of the spring 73 is fixedly mounted on the top of the protective cover 72, and the other end of the spring 73 is fixedly mounted on the inner wall of the sleeve 71. The elasticity of the spring 73 and the protective cover 72 can make the steel balls 74 at the bottom tightly attached to the surface of the steel plate.

[0024] Specifically, the protective cover 72 is provided with an auxiliary mechanism 8 for protecting the laser emitting head 5, and the auxiliary mechanism 8 includes a bolt 81, a slider 82, a baffle 83, and a connecting rod 84; the bolt 81 is rotatably connected to the outer wall of the protective cover 72, the outer wall of the bolt 81 is threadedly connected to the slider 82, and the inner wall of the protective cover 72 is slidably connected to the baffle 83, and the number of the baffles 83 is two groups, and the two groups of baffles 83 are mirror-imaged on the inner wall of the protective cover 72 with the bolt 81 as the central axis. When the two groups of baffles 83 are fitted together, the bottom of the protective cover 72 can be covered by the two groups of baffles 83, so that the bottom of the protective cover 72 remains in a closed state. At this time, the sleeve 71 cooperates with the protective cover 72 and the baffle 83 to cover the laser emitting head 5 as a whole, so as to protect the laser emitting head 5 and prevent the laser emitting head 5 from being contaminated by impurities. The outer wall of the baffle 83 is hinged with a connecting rod 84, and the end of the connecting rod 84 away from the baffle 83 is hinged at the bottom of the slider 82. The bolt 81 is rotated to drive the slider 82 threadedly connected thereto to move toward the end away from the protective cover 72. At the same time, the slider 82 will pull the two sets of connecting rods 84, and then the two sets of connecting rods 84 will pull the two sets of baffles 83, so that the two sets of baffles 83 will slide synchronously in opposite directions on the inner wall of the protective cover 72 and approach each other.

[0025] Working principle: first place the steel plate on the storage table 3, then start the cylinder 6 to drive the laser transmitter 5 to move downward, so that the laser transmitter 5 drives the sleeve 71 and the protective cover 72 to move downward synchronously until the steel ball 74 at the bottom of the protective cover 72 fits the upper surface of the steel plate. At this time, the protective cover 72 and the sleeve 71 can be used to cover the cutting part of the steel plate by the laser transmitter 5 to prevent sparks from flying when the steel plate is cut and accidentally injuring the staff.

[0026] When the laser transmitter 5 is not in use, the bolt 81 is rotated to drive the slider 82 threadedly connected thereto to move toward the end away from the protective cover 72. At the same time, the slider 82 will pull the two sets of connecting rods 84, and then the two sets of connecting rods 84 will pull the two sets of baffles 83, so that the two sets of baffles 83 slide synchronously in opposite directions on the inner wall of the protective cover 72 and approach each other until the two sets of baffles 83 fit together. At this time, the two sets of baffles 83 can be used to cover the bottom of the protective cover 72, so that the bottom of the protective cover 72 remains in a closed state. At this time, the sleeve 71 cooperates with the protective cover 72 and the baffle 83 to cover the laser transmitter 5 as a whole, thereby protecting the laser transmitter 5 and preventing the laser transmitter 5 from being contaminated by impurities.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
