Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting heads, and particularly relates to a laser cutting head convenient for cleaning. Background Art

[0002] Laser cutting uses a high-power density laser beam to irradiate the material to be cut, causing the material to be rapidly heated to the vaporization temperature, evaporating to form holes. As the beam moves relative to the material, the holes continuously form a very narrow slit, thereby completing the cutting of the material.

[0003] Existing laser cutting machines generally consist of a machine body, a slide rail, a sliding mounting seat, and a laser cutting head. During the laser cutting process, some metal particles will be generated. Whenever the cutting operation is completed, some metal particles often adhere to the surface of the laser cutting head. If not cleaned in time, it may affect the normal flow direction of the cutting air flow during the next use, resulting in poor cutting quality. Therefore, the existing laser cutting heads need to be frequently disassembled and cleaned. However, when the existing laser cutting heads are disassembled and cleaned, it is inconvenient to stably hold them, and there is a risk of accidental dropping when grasping and cleaning, which may cause damage to the parts of the laser cutting head and is not convenient for safe cleaning.

[0022] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] This embodiment provides a laser cutting head that is convenient to clean. When the laser cutting head is disassembled and cleaned, it is more conducive to the cleaning operator to stably hold the cutting head. Specifically, as Figures 1 - 4 shown, it includes a laser cutting head 1 and two groups of clamping units 2. Two concave plates 11 are provided on the surface of the laser cutting head 1. The concave part of the concave plate 11 is designed as a semicircle. A rubber pad 4 is provided in the concave part of the concave plate 11. The two groups of clamping units 2 are respectively arranged between the two concave plates 11 and the two sides of the laser cutting head 1. Each group of clamping units 2 includes a clamping plate 21 and a spring 22. Two arc-shaped convex plates 211 are provided on the surface of each clamping plate 21 and are located inside the concave plate 11. The multiple arc-shaped convex plates 211 are respectively close to the concave parts of the two concave plates 11. A through groove 214 is provided on the surface of the clamping plate 21 and near the position between the two arc-shaped convex plates 211. The two arc-shaped convex plates 211 and the through groove 214 are designed as a semicircle. The two springs 22 are respectively located between the opposite surfaces of the two clamping plates 21 and the two sides of the laser cutting head 1. The spring 22 is in a compressed state, so that the cleaning operator can insert the fingers of the hand between the clamping plate 21 and the concave plate 11, and then use the resilience of the spring 22 to cooperate with the clamping plate 21 to achieve the clamping effect between the operator's hand and the concave plate 11, so that the operator can stably hold the laser cutting head 1 for operation, which is more conducive to safe cleaning operation and prevents the phenomenon of accidental dropping due to slipping.

[0025] To enable the clamping unit 2 to be stably located inside the concave plate 11, as Figure 1 、 Figure 2 and Figure 4As shown in the figure, in this embodiment, two sliding grooves 111 are penetrated through the surface of the concave plate 11. A convex protrusion 212 protruding into the sliding groove 111 is provided on the surface of the clamping plate 21. The diameter of the convex protrusion 212 is adapted to the diameter of the sliding groove 111. Both the surface of the laser cutting head 1 and the surface of the clamping plate 21 are provided with a first convex block 12 and a second convex block 213. The first convex block 12 and the second convex block 213 both protrude into the inner side of the spring 22. Thus, the cooperation between the convex protrusion 212 and the sliding groove 111 can be effectively utilized to limit the clamping plate 21. At the same time, the first convex block 12 and the second convex block 213 are used to ensure the stability of the spring 22, effectively avoiding the phenomenon that the clamping plate 21 and the spring 22 are displaced forward and backward.

[0026] For the convenience of cleaning, the operator can insert the fingers of the hand between the clamping plate 21 and the concave plate 11. As Figures 1 - 3 shown in the figure, in this embodiment, a push plate 3 is provided between multiple convex protrusions 212. The two push plates 3 are respectively located on the sides far away from each other of the two concave plates 11. A gap is left between the inner sides of the two push plates 3 and the sides far away from each other of the two concave plates 11. Grooves 31 are provided on the surfaces of the two push plates 3. Anti-slip patterns are engraved on the surface of the push plate 3 near the position where the grooves 31 are opened. The surface of the push plate 3 is a smooth surface, and the corners of the push plate 3 are all designed to be round. So that the cleaning operator can push the push plate 3 and cooperate with the gap reserved between the push plate 3 and the concave plate 11 to push the clamping unit 2, which is convenient for the operator to insert the fingers of the hand into the concave plate 11 subsequently.

[0027] When the above laser cutting head needs to be cleaned, the cleaning operator can make the thumb and index finger of the hand correspond to the grooves 31 opened on the two push plates 3 respectively after disassembling the cutting head, and squeeze the two push plates 3 towards the opposite side. The push plate 3 drives the clamping plate 21 to move, and the inner side of the concave plate 11 moves away and the opening gradually becomes larger. The spring 22 is compressed and contracted. Subsequently, the operator can insert the thumb and index finger of the grasping hand between the clamping plate 21 and the inner side of the concave plate 11 respectively, and slowly release the push plate 3. The spring 22 rebounds until the clamping effect of the hand is achieved by the cooperation between the concave plate 11, the arc-shaped convex plate 211 and the clamping plate 21. Thus, the laser cutting head 1 can be effectively restricted to the hand of the operator, which is more conducive to safe cleaning and prevents dropping due to slipping out of the hand.

[0028] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
