Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a capillary laser cutting support fixture and a laser cutting machine. 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 irradiates the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. Laser cutting is widely used due to its high precision, good repeatability, and no damage to the material surface.

[0003] Capillary refers to a metal tube with an outer diameter of less than 6mm. Due to the small diameter of the capillary, when it is processed by a traditional laser cutting machine, the capillary is clamped by a fixture and extended to the section to be processed. Under the influence of its own gravity, the capillary will produce a slight downward deformation; at the same time, during processing, the capillary itself rotates and shakes, which will affect the processing accuracy. Utility Model Content

[0007] Preferably, a material guide port is provided at the other end of the supporting cylinder.

[0008] A laser cutting machine comprises a frame, a hollow shaft motor, an X-axis module, a Y-axis module, a laser cutting head, a clamping bracket and the above-mentioned supporting fixture, wherein the hollow shaft motor is installed on the frame and is used to clamp the capillary to be processed, the X-axis module is installed on the top of the frame, the Y-axis module is installed on the X-axis module, the laser cutting head is installed on the Y-axis module, the clamping bracket is installed on the X-axis module, and the supporting cylinder is installed on the clamping bracket.

DETAILED DESCRIPTION

[0017] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0018] like Figure 1-2 As shown, a capillary laser cutting support jig has a main body comprising a support cylinder 10. A guide hole 11 is provided at the center of the support cylinder 10. The guide hole 11 is used to pass the capillary to be processed and to support the capillary. One end of the support cylinder 10 is cut in half axially to form a working surface 12. A slag penetration groove 13 is provided at the bottom of the working surface 12. The slag generated by the processing falls from the slag penetration groove 13. When the capillary is cut, the capillary is fixed in the guide hole 11, thereby avoiding the movement of the capillary.

[0019] Furthermore, an oil dripping hole 14 is provided at the top of the supporting cylinder 10, and the oil dripping hole 14 is communicated with the guide hole 11. The oil dripping hole 14 is used to drip lubricating oil into the guide hole 11. Since the capillary will rotate during processing and generate friction with the guide hole 11, the lubricating oil can facilitate the axial movement and rotation of the capillary in the guide hole 11.

[0020] A material guide port 15 is provided at the other end of the supporting cylinder 10 . The material guide port 15 is trumpet-shaped, and the center of the material guide port 15 is connected to the guide hole 11 , so as to facilitate the capillary to be processed to be inserted into the guide hole 11 .

[0021] The above-mentioned support fixture cooperates with the laser cutting machine to perform laser cutting of the capillary. The laser cutting machine is introduced below. Figure 3-5 As shown: the laser cutting machine includes a frame 20, a hollow shaft motor 30, an X-axis module 40, a Y-axis module 50, a laser cutting head 60, a clamping bracket 70 and the above-mentioned supporting fixture. The hollow shaft motor 30 is installed on the frame 20 for clamping the capillary to be processed. The X-axis module 40 is installed on the top of the frame, and the Y-axis module 50 is installed on the X-axis module 40. The laser cutting head 60 is installed on the Y-axis module 50 through the Z-axis module. The X-axis module, the Y-axis module and the Z-axis module are used to drive the laser cutting head 60 to move.

[0022] The clamping bracket 70 is installed on the X-axis module 40 so that it can move with the X-axis module 40 , and the supporting cylinder 10 is installed on the clamping bracket 70 .

[0023] Specifically, the clamping bracket 70 includes a support arm 71, a chuck 72 and a pneumatic caliper 73. The support arm 71 is installed on the X-axis module 40. The chuck 72 and the pneumatic caliper 73 are both fixedly installed on the support arm 71. The support cylinder 10 is detachably installed on the chuck 72, thereby facilitating the replacement of fixtures of different specifications.

[0024] Working process: first, the capillary to be processed passes through the hollow shaft motor 30 into the guide hole 11 until it enters the working surface 12, and the support cylinder 10 supports and fixes the capillary so that it cannot move horizontally or vertically; then the pneumatic chuck on the hollow shaft motor 30 clamps the capillary, and the rotation of the hollow shaft motor 30 drives the capillary to rotate, and the laser cutting head 60 is used for cutting processing, and the waste slag generated by the processing falls from the slag groove 13.

[0025] When one section of processing is completed, the pneumatic chuck on the hollow shaft motor 30 is released, the pneumatic caliper 73 clamps the capillary, and the X-axis module moves to the right, so that the capillary in the rear section moves to the right to the working surface 12, the pneumatic caliper 73 is released, the pneumatic chuck on the hollow shaft motor 30 clamps the capillary, and then rotates and cuts; this cycle can be used for continuous processing.

[0026] It should be noted that the diameter of the guide hole 11 is slightly larger than the outer diameter of the capillary to be processed to achieve a fixing effect; for capillaries of different diameters, multiple support jigs with different inner diameters of guide holes 11 can be designed, and the support jigs can be easily installed and removed from the chuck 72; at the same time, the jig has a simple structure, low cost, easy production, and is very practical.

[0027] In summary, the support fixture with guide holes is designed according to the characteristics of the capillary. The fixture has a simple structure and can effectively solve the problems of shaking and deformation during capillary laser cutting.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
