Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to an anti-collision device for laser cutting machines. Background Art

[0002] Laser cutting is the process of focusing the laser emitted from a laser into a high-power density laser beam through an optical path system. The laser beam is irradiated onto the workpiece to cut it. At the same time, a high-pressure nozzle is installed on the laser cutting machine to blow away the molten metal particles. The continuous movement of the workpiece eventually forms a cut in the material, thereby achieving the purpose of cutting.

[0003] For example, an anti-collision device for a laser cutting machine with publication number CN215787562U includes a mounting seat, a slide rail is provided at the middle position of a side wall of one side of the mounting seat, the slide rail is connected to the mounting groove, and an anti-collision mechanism is provided on one side of the slide rail close to the mounting head. The present application uses the protective rod and spring in the anti-collision assembly to raise and lower the cutting head when the cutting head cuts an uneven workpiece to avoid contact with the workpiece, thereby preventing the laser cutting head from being damaged by collision.

[0004] When the above device is in use, the cutting head is driven away from the cutting workpiece by raising and lowering the anti-collision mechanism. In this process, when the installed protective rod moves on the surface of the workpiece, the overall friction force is large, which will affect the movement of the cutting head. At the same time, when the cutting head descends, it will be reset by the elastic force of the spring, and the cutting head will bounce back and forth slightly, which will easily cause the cutting head to have an uneven cutting surface when operating on the workpiece.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] See also Figures 1 to 5 , which is the first embodiment of the utility model, provides a technical solution: a laser cutting machine anti-collision device, comprising an operating table 1 and a movable guide rail 2 arranged on the operating table 1, the movable guide rail 2 is used to move the cutting machine 3 as a whole to cut the workpiece, the cutting machine 3 is arranged on the movable guide rail 2, a cutting head 4 is arranged on one side of the cutting machine 3, the cutting head 4 is used to emit laser to cut the workpiece into a desired shape, and an anti-collision component 5 is arranged outside the cutting head 4, the anti-collision component 5 is used to prevent the cutting head 4 from colliding with the material during the cutting operation;

[0027] The anti-collision component 5 includes a placement seat 51 arranged outside the cutting head 4, the placement seat 51 is used to place the protective plate 56 and the matching ring plate 58, a fixed block 52 symmetrically arranged in the placement seat 51, a support plate 53 arranged on one side of the fixed block 52, the support plate 53 is used to rotate the connecting gear 54, so that the gear 54 can rotate under the drive of the first rack 55, the gear 54 arranged on the end of the support plate 53 away from the fixed block 52, meshing with the first rack 55 arranged on one side of the gear 54, and a protective plate 56 arranged on the side of the first rack 55 away from the gear 54. The protective plate 56 is a ring-shaped plate, which is convenient for retraction when encountering an uneven workpiece.

[0028] A second rack 57 is provided on the side of the gear 54 away from the first rack 55, and a matching ring plate 58 is provided on the side of the second rack 57 away from the gear 54. When the matching ring plate 58 is extended by the second rack 57, the entire protective effect can be reinforced.

[0029] The placement seat 51 is in a U-shaped ring shape, and a slide groove 511 is formed through the placement seat 51 . The slide groove 511 is used to cooperate with the sliding rod 6 to displace the protection plate 56 and the matching ring plate 58 provided on the sliding rod 6 .

[0030] During use, the protective plate 56 is always in contact with the workpiece. When the workpiece becomes uneven, the protective plate 56 can be retracted. When the protective plate 56 is retracted, the first rack 55 fixed to it will drive the meshing gear 54 to rotate, so that the second rack 57 meshing on the other side of the gear 54 drives the matching ring plate 58 to extend. During the extension of the matching ring plate 58, the retraction of the protective plate 56 is limited to a certain extent to prevent the protective plate 56 from being over-retracted and causing contact between the cutting head 4 and the workpiece. At the same time, during the entire protective function, the cutting head 4 will always cut the surface of the workpiece, and the uneven cutting surface will not occur during the cutting process.

[0031] Example 2

[0032] See also Figures 1 to 5 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0033] Ball bearings 59 are arranged in an array on one side of the protective plate 56 and the matching ring plate 58, and the ball bearings 59 are used to reduce the friction between the workpiece, and a sliding rod 6 is arranged on the side close to the placement seat 51, and the sliding rod 6 is used to limit the movement between the protective plate 56 and the matching ring plate 58 to avoid angular deflection of the two when moving, which will cause errors in the entire internal linkage.

[0034] An array of telescopic rods 581 is arranged on one side of the mating ring plate 58 close to the inner cavity of the placement seat 51. A spring 582 is sleeved on the outside of the telescopic rod 581, and both ends of the spring 582 are fixedly connected to the placement seat 51 and the mating ring plate 58 respectively. The spring 582 is used to always provide a pulling force to the mating ring plate 58 so that the protective plate 56 is always in contact with the surface of the workpiece.

[0035] A control panel 11 is disposed on one side of the operating table 1 , and the control panel 11 is used to control the cutting head 4 to perform cutting. A conveying plate 12 is disposed on the operating table 1 .

[0036] During use, when the workpiece is transported to the cutting area, the cutting machine 3 installed on the moving guide rail 2 can cut the workpiece. The control board 11 controls the entire cutting process, and the ball 59 installed on the protective plate 56 and the matching ring plate 58 can reduce friction to the greatest extent, so that the entire cutting machine 3 will not be obstructed during the movement. At the same time, the contact between the protective plate 56 and the workpiece is completely determined by the thickness of the workpiece itself. With the cooperation between the gear 54, the first rack 55 and the second rack 57, the spring 582 set on the matching ring plate 58 provides a stable force for the fitting state of the protective plate 56, thereby avoiding the situation where the protective plate 56 cannot fit with the surface of the workpiece during the protection process, thereby completing the protection of the cutting head 4.

[0037] The remaining structures are the same as those of Example 1.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
