Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a laser cutting machine and a cutting head for the laser cutting machine. Background Art

[0002] Laser cutting machine technology uses the energy released when the laser beam hits the surface of the metal sheet. The metal sheet is melted and the slag is blown away by the gas. Since the laser power is very concentrated, only a small amount of heat is transferred to other parts of the metal sheet, causing little or no deformation. The laser can be used to cut complex shapes of blanks very accurately, and the cut blanks do not need to be further processed.

[0003] Most of the cutting heads used in existing laser cutting machines are fixed on the surface of the laser cutting machine by bolts, which requires workers to carry tools and perform multiple operations, greatly wasting manpower and reducing the installation efficiency of the cutting head.

DETAILED DESCRIPTION

[0035] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0036] like Figures 1 to 5As shown, the embodiment of the utility model provides a laser cutting machine and a cutting head for the laser cutting machine, comprising: a mounting block 1; a cutting head body 2, fixedly connected to the lower surface of the mounting block 1, for laser cutting; a housing 3, placed on the surface of the mounting block 1 and fixedly connected to the laser cutting machine; a connecting device 4, arranged on the surface of the mounting block 1 and the housing 3, to achieve rapid installation of the cutting head body 2; a cleaning device 5, arranged on the side wall of the housing 3, to achieve cleaning of the lens in the cutting head body 2. By providing the connecting device 4, it is convenient to quickly install and disassemble the cutting head, saving human resources, and by providing the cleaning device 5, the lens of the cutting head body 2 can be cleaned, improving the practicality of the cutting head.

[0037] like Figures 1 to 4 As shown, the connecting device 4 includes four support plates 41, the support plates 41 are fixedly connected to the housing 3, the four support plates 41 are in groups of two, the inner wall of the housing 3 is slidably connected with four clamping blocks 42, the four clamping blocks 42 are in groups of two, the clamping blocks 42 and the support plates 41 are fixedly connected with a spring 43 on one side close to each other, and the side wall of the mounting block 1 is provided with four clamping grooves 44, the sizes of the clamping blocks 42 and the clamping grooves 44 are adapted. First, the mounting block 1 is pushed into the housing 3, at which time the clamping block 42 contacts the mounting block 1 and moves when blocked by the mounting block 1, at which time the clamping block 42 moves away from the mounting block 1 and drives the spring 43 to contract, when the mounting block 1 completely enters the housing 3, the clamping block 42 and the clamping groove 44 are in the same horizontal plane, at which time the clamping block 42 loses the blocking of the mounting block 1 and is inserted into the clamping groove 44 under the action of the elastic force of the spring 43, thereby completing the installation of the cutting head body 2. The surface of the clamping block 42 is rotatably connected with a plurality of balls 45, and the balls 45 are spherical structures. When the clamping block 42 contacts and slides on the surface of the mounting block 1 , the ball bearings 45 can reduce the friction between the clamping block 42 and the mounting block 1 , thereby facilitating the insertion of the clamping block 42 into the clamping slot 44 .

[0038] like Figures 1 to 4As shown, the two support plates 41 are slidably connected to a connecting frame 46 on one side close to each other, the connecting frame 46 and the block 42 are fixedly connected, and a magnet block 47 is fixedly connected to the surface of the connecting frame 46. The support plate 41 is an iron plate. When the block 42 is inserted into the slot 44, the magnet block 47 contacts the support plate 41. At this time, the connecting frame 46 is fixed on the support plate 41 under the action of the magnet block 47, thereby improving the stability of the connecting frame 46 and the block 42 and reducing the separation between the block 42 and the slot 44. Pulling the connecting frame 46 can drive the block 42 away from the mounting block 1, and the cutting head body 2 can be disassembled at this time. A positioning rod 48 is fixedly connected to the inner wall of the shell 3, and a positioning groove 49 is opened on the upper surface of the mounting block 1. The sizes of the positioning rod 48 and the positioning groove 49 are matched. When the mounting block 1 enters the shell 3, the positioning rod 48 and the positioning groove 49 are aligned. When the mounting block 1 moves, the positioning rod 48 is inserted into the positioning groove 49, thereby limiting the moving range of the mounting block 1 and improving the installation efficiency of the cutting head body 2.

[0039] In the embodiment of the utility model (working principle), when installing the cutting head body 2, the mounting block 1 is placed in the shell 3. At this time, the clamping block 42 contracts under the action of the mounting block 1 and drives the spring 43 to contract. When the mounting block 1 completely enters the shell 3, the elastic force of the spring 43 drives the clamping block 42 to insert into the clamping slot 44, thereby completing the installation of the cutting head body 2. Pull the connecting frame 46 to drive the clamping block 42 away from the mounting block 1, and the cutting head body 2 can be disassembled.

[0040] like Figure 2 and Figure 5 As shown, the cleaning device 5 includes a fixed plate 51, which is fixedly connected to the side wall of the housing 3, and an electric telescopic rod 52 is fixedly connected to the surface of the fixed plate 51, and one end of the electric telescopic rod 52 is fixedly connected to a support frame 53, and a cleaning brush 55 is placed on the surface of the support frame 53. The material of the cleaning brush 55 is dust-free cotton, and a sensor 56 is fixedly connected to the side wall of the support frame 53. A controller 57 is fixedly connected to the surface of the fixed plate 51, and the sensor 56 and the controller 57 are electrically connected, and the controller 57 and the electric telescopic rod 52 are electrically connected. When the sensor 56 detects that the lens of the cutting head body 2 is contaminated with dust, the signal is transmitted to the controller 57, and the controller 57 analyzes the signal and controls the electric telescopic rod 52 to extend and retract. At this time, the cleaning brush 55 can clean the lens of the cutting head body 2, thereby reducing the situation where dust adheres to the lens of the cutting head body 2 and affects the working efficiency of the cutting head. The surface of the support frame 53 is fixedly connected with a plurality of pointed protrusions 54, which are of a conical structure. When the cleaning brush 55 is placed on the support frame 53, the pointed protrusions 54 are in contact with and inserted into the cleaning brush 55, which can improve the stability of the cleaning brush 55 and facilitate the regular replacement of the cleaning brush 55.

[0041] In the embodiment of the utility model, the cleaning brush 55 is fixed by means of the pointed protrusion 54, and then the electric telescopic rod 52 is driven to work through the sensor 56 and the controller 57. At this time, the cleaning brush 55 cleans the cutting head body 2, thereby improving the practicality of the cutting head.

[0042] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
