Description

Technical Field

[0001] The utility model relates to the technical field of laser processing, in particular to a clamp for laser processing. Background Art

[0002] Friction and wear performance is an important property of solid surfaces. Studies have shown that micro-textures of certain specific shapes can effectively improve the friction and drag reduction performance of solid surfaces. These materials with microstructures on the surface have good friction and drag reduction, hydrophobicity, self-cleaning and other properties and have broad application prospects in production and life. In addition to using chemical etching and other methods to prepare surface micro-textures, high-laser processing is currently a good choice. With the development of short-wavelength and short-pulse lasers, laser micro-nano processing technology has become one of the important means of preparing surface micro-nano textures;

In this process, a large amount of dust particles will be generated, which are difficult to collect and affect the processing accuracy. Utility Model Content

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on the present utility model. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0029] The implementation of the utility model is described in detail below in conjunction with specific embodiments.

[0030] In this embodiment:

[0031] Reference Figure 1-2 As shown, a preferred embodiment of the utility model is provided.

[0032] The laser processing fixture of this embodiment includes a base 1 and a chuck 2, wherein a connector 11 is disposed between the ends of the base 1 and the chuck 2, and the two connectors 11 are connected by a rotating shaft, and an inclined support rod 15 connected to the rotating shaft at the other end of the chuck 2 and driving the chuck 2 to be raised and lowered is installed inside the other end of the base 1;

[0033] A turntable 3 is rotatably installed inside the chuck 2, and a top cover 33 is provided on the top of the turntable 3. A vibration motor 7 is installed inside the turntable 3 to vibrate the dust dropped during the processing. A splitting vise 5 with an opening and closing setting is installed on the turntable 3. The irregular workpiece is clamped and fixed by the splitting vise 5. A dust removal plate 6 is also provided at one end of the chuck 2 to remove dust generated during the laser processing of the workpiece.

[0034] Furthermore, if Figure 4 As shown, an angle adjustment motor 12 is installed at the end of the base 1, and the output shaft of the angle adjustment motor 12 is connected to a first guide rod 13, and the external thread of the first guide rod 13 is connected to a first connecting block 14, and one end of the diagonal support rod 15 is connected to the rotating shaft of the first connecting block 14. The first guide rod 13 is driven to rotate by the angle adjustment motor 12, and the first connecting block 14 connected with the external thread is pushed to slide inside the base 1, so that one end of the chuck 2 is lifted up or lowered along the connecting head 11 through the diagonal support rod 15, so as to adjust the inclination angle of the workpiece during processing.

[0035] Furthermore, a steering adjustment motor 4 is installed at the bottom of the chuck 2, and a connecting shaft 31 that passes through the chuck 2 is connected in the middle of the bottom of the turntable 3. The steering adjustment motor 4 and the connecting shaft 31 are connected via a gear meshing transmission. The steering adjustment motor 4 drives the connecting shaft 31 to rotate, thereby driving the parting vise 5 installed on the turntable 3 to rotate, so as to drive the workpiece to perform a direction adjustment operation, and also enable the dust accumulated on the top cover 33 and the parting vise 5 during the processing to be collected by the dust removal plate 6.

[0036] It is worth noting that, referring to Figure 3 As shown, a vibration head 71 is installed at the vibration output end of the vibration motor 7, the end of the vibration head 71 is in contact with the bottom of the top cover 33, and the material of the vibration head 71 is hard silicone. High-frequency vibration is generated by the vibration motor 7, and the vibration head 71 is used to transmit the vibration to the top cover 33, so that the dust accumulated above the top cover 33 and on the parting vise 5 is vibrated to facilitate the suction by the dust removal plate 6, thereby improving the collection effect.

[0037] In order to ensure that the dust generated during the laser processing process does not affect the performance of the equipment, a support plate 32 is provided in the middle of the top of the turntable 3. Two second guide rods 53 are connected with bearings between the support plate 32 and the inner wall of the turntable 3. The two second guide rods 53 correspond to the parting vise 5. The support plate 32 is perpendicular to one side of the two second guide rods 53 and is connected with a clamping rod 54 that passes through the outside of the turntable 3. The end of the clamping rod 54 is connected with the two second guide rods 53 through a meshing transmission connection between a bevel gear and the two second guide rods 53. The surfaces of the two second guide rods 53 are respectively provided with forward threads and reverse threads. The outer surface of the second guide rod 53 is connected with a clamping rod 54 that passes through the outside of the turntable 3. The second connecting block 52 is connected by a thread, and one side of the second connecting block 52 is connected to an opening and closing frame 51 that passes through the outside of the turntable 3. The opening and closing frame 51 is arranged in a C shape, and the other end of the opening and closing frame 51 is connected to the end of the parting vise 5. By rotating the clamping rod 54, the two second guide rods 53 can be driven to rotate synchronously, thereby pushing the second connecting block 52 connected with the forward and reverse threads at both ends thereof to realize reverse synchronous transmission, and then the opening and closing of the two parting vises 5 are adjusted by using the opening and closing frame 51. Since the mechanism is hidden between the turntable 3 and the top cover 33, the dust generated will not affect its internal structure.

[0038] In addition, a dust suction groove 61 is provided on one side of the dust removal plate 6 close to the turntable 3, and the lower groove wall of the dust suction groove 61 is on the same horizontal line with the upper surface of the top cover 33, thereby ensuring that the dust accumulated on the top cover 33 can be collected, and a negative pressure hole that passes through the dust suction groove 61 is provided on the other side of the dust removal plate 6, and the negative pressure hole is used to connect a negative pressure generator in series, thereby realizing the negative pressure dust suction operation of the dust suction groove 61.

[0039] 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 and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
