Description

Technical Field

[0001] The utility model relates to the technical field of laser machine tool clamps, in particular to a machine tool clamping device used for laser machinery manufacturing. Background Art

[0002] Laser cutting is a processing method that uses a high-energy laser beam to irradiate the surface of the material, causing the material to quickly melt, vaporize, ablate or reach the ignition point, and at the same time uses a high-speed airflow coaxial with the beam (such as oxygen, nitrogen, argon, etc.) to blow away the molten material, thereby cutting the material. This processing method has the characteristics of high precision, high speed and high flexibility. Metal plates usually do not have a suitable clamp to fix the plates before cutting. The plates can only rely on their own weight and the tapered tooth shape of the cutting table to limit the friction of the plates to prevent them from moving during the cutting process. During the laser cutting process of metal plates, the metal plates will shake or shift due to the heat and mechanical stress generated by laser cutting, which will affect the change error of the laser cutting shape and need to be improved. Therefore, we propose a machine tool clamping device for laser machinery manufacturing. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1, as Figure 1-3 As shown, the utility model provides a technical solution: a machine tool clamping device for laser machinery manufacturing, including a laser machine tool storage table 10, a clamping block 1 arranged on the surface of the laser machine tool storage table 10, the laser machine tool storage table 10 is composed of a plurality of parallel serrated support tables, a serrated groove 101 is formed on the bottom of the clamping block 1 to match the top of the laser machine tool storage table 10, two round rods 4 are provided through the surface of the clamping block 1, a clamping block 5 is fixedly provided at the bottom end of the round rod 4, a spring A2 is embedded on the top of the round rod 4, and a ring body seat 3 for limiting the spring A2 is threadedly connected to the top of the round rod 4;

[0020] A horizontal plate 6 is fixedly provided on one side of the clamping block 1, and a vertically adjustable pressure plate 8 is provided at the bottom of the horizontal plate 6. A spring B9 is connected between the horizontal plate 6 and the pressure plate 8. A bolt 7 for adjusting the vertical position of the pressure plate 8 is threadedly connected to the middle of the horizontal plate 6.

[0021] In a specific embodiment of the present invention, the assembly process of the clamping block 1 and the laser machine tool storage table 10 is as follows: first, the position of the clamping block 1 is determined, and the round rod 4 is rotated so that the clamping block 5 is staggered with the sawtooth support platform of the laser machine tool storage table 10. Then, the clamping block 1 can be placed vertically to fit the laser machine tool storage table 10. By pressing the round rod 4, the clamping block 5 is lowered to the bottom of the sawtooth support platform and the round rod 4 is rotated so that the clamping block 5 is in close contact with the bottom of the sawtooth support platform (such as Figure 1 As shown) Spring A2 is in a compressed state. At this time, the clamp 1 cannot move in any direction on the laser machine tool platform 10. After the assembly is stable, adjust the bolt 7 and push the pressure plate 8 to close to the surface of the workpiece (as shown). Figure 2 As shown in the figure), when the pressure plate 8 is pressed against the workpiece, the spring B9 is in a stretched state. After loosening the bolt 7, the spring B9 pulls the pressure plate 8 to lift and reset. When the clamping block 1 needs to be removed, the round rod 4 needs to be rotated so that the clamping block 5 is staggered with the serrated support platform. The rebound force of the spring A2 lifts the round rod 4. At this time, the clamping block 1 can be easily taken out vertically. If the workpiece is a metal plate with a large area, it needs to be fixed at multiple points, and at least four clamping jaws are used.

[0022] In the preferred technical solution, the spacing between the two round rods 4 is the horizontal width of the four adjacent serrated support platforms, and the two round rods 4 are respectively located on the outside of the two outermost serrated support platforms of the four adjacent serrated support platforms. When the clamping blocks 5 of the two round rods 4 are in close contact with the bottom of the serrated support platforms, the vertical direction and the length direction of the clamping blocks 5 are both limited, and the serrated groove 101 of the clamping block 1 fits perfectly with the tooth groove of the laser machine tool storage table 10, so that the clamping claw device can realize the function of quick disassembly and assembly.

[0023] In the preferred technical solution, the ring seat 3 includes a conical base and a ring body. The conical base is located on the top of the spring A2. The conical base is used to limit the spring A2 from detaching from the top of the round rod 4. The ring body facilitates the lifting and lowering of the round rod 4.

[0024] In the preferred technical solution, four polished rods 801 are fixedly provided on the top of the pressing plate 8, and the four polished rods all penetrate the cross plate 6. The polished rods 801 play a role in improving the stability of the pressing plate 8 during the lifting and lowering process.

[0025] In the preferred technical solution, a pressing piece is embedded in the bottom of the bolt 7 to increase the contact area with the pressure plate 8. A hexagonal groove is provided on the top surface of the bolt 7, and the hexagonal groove can be rotated and adjusted with an external hexagonal wrench.

[0026] In the preferred technical solution, a plurality of friction protrusions are provided on the bottom surface of the pressing plate 8 to increase the contact friction between the pressing plate 8 and the surface of the workpiece.

[0027] Working principle: The serrated groove 101 of the clamping block 1 fits perfectly with the tooth groove of the laser machine tool storage table 10, and then the two round rods 4 are pressed to make the clamping block 5 respectively clamped on the bottom of the serrated support platform of the laser machine tool storage table. By rotating the bolt 7, the pressure plate 8 is adjusted to press and fit with the surface of the workpiece, thereby temporarily fixing the workpiece. When disassembling, you only need to rotate the round rod 4 to make the clamping block 5 staggered with the serrated support platform to vertically remove the clamping block 1.
