Description

Technical Field

[0001] This utility model belongs to the field of cutting frame technology, and in particular relates to an adjustable frame for laser cutting. Background Technology

[0002] Laser cutting utilizes a focused, high-power-density laser beam to irradiate a workpiece, causing the irradiated material to rapidly melt, vaporize, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the laser beam blows away the molten material, thereby cutting the workpiece. It is one of the thermal cutting methods for cutting workpieces.

[0003] Currently, when laser cutting machines are used, operators need to place the workpiece under the machine and align it so that the machine is centered on the workpiece. After each cut, the workpiece needs to be moved forward slightly and re-centered. This positioning method is cumbersome, delays the cutting progress, and reduces cutting efficiency. In addition, the dust generated during cutting can easily adhere to the surface of the machine frame's slide rails, which can cause the machine to jam when moving after prolonged use. Utility Model Content

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This utility model embodiment provides an adjustable frame for laser cutting, such as... Figure 1-3 As shown, the system includes a base plate 1, a longitudinal frame 2 mounted on the top of the base plate 1, a slide rail and a longitudinal slide table 3 mounted on the top of the longitudinal frame 2, a transverse frame 4 mounted on the right side of the longitudinal slide table 3, a slide rail and a transverse slide table 5 mounted on the surface of the transverse frame 4, a laser cutter 6 mounted on the front side of the transverse slide table 5, a cutting table 7 mounted on the right side of the center of the longitudinal frame 2, two sets of sliding grooves symmetrically formed on the surface of the cutting table 7, with a slider 8 slidably embedded in the grooves, a connecting frame 9 fixedly inserted at the center of the slider 8, a first clamping block 10 mounted on the top of the connecting frame 9, a connecting block 11 mounted on the bottom of the connecting frame 9, and an electric cylinder 12 mounted at the center of the bottom of the cutting table 7. The output shaft is connected to a mounting bracket 13. Connecting rods 14 are hinged to both the left and right sides of the mounting bracket 13. The other ends of the two sets of connecting rods 14 are respectively hinged to two sets of connecting blocks 11. When using this device, the workpiece to be cut can be placed on the cutting table 7. Then, the electric cylinder 12 is started, and the electric cylinder 12 pushes the mounting bracket 13. The mounting bracket 13 pulls the two sets of connecting blocks 11 through the connecting rods 14. The two sets of connecting brackets 9 move closer to each other under the action of the connecting blocks 11, so that the two sets of first clamping blocks 10 position the workpiece, so that the workpiece is accurately placed at the center of the cutting table 7 and clamped and fixed. This setting is more convenient and faster than manual observation and positioning, and the positioning accuracy is high.

[0020] The connecting block 11 is hollow inside and has a first motor 15 installed inside. The connecting frame 9 is also hollow inside and has a rotating shaft 16 rotatably mounted inside. The output shaft of the first motor 15 is connected to the bottom of the rotating shaft 16. The top of the rotating shaft 16 extends to the top outer side of the connecting frame 9 and is connected to the first clamping block 10. The first clamping block 10 is cylindrical. With the first motor 15 and the rotating shaft 16 installed, the first motor 15 can be started after one of the cutting points on the workpiece surface is cut. The first motor 15 drives the first clamping block 10 to rotate through the rotating shaft 16. The first clamping block 10 is close to the side wall of the workpiece and rotates. This setting allows the workpiece to be pushed forward, making the workpiece cutting work more labor-saving.

[0021] The upper end of the connecting frame 9 extends to the rear side of the first clamping block 10 and a connecting shaft 17 is rotatably mounted inside. A second clamping block 18 is mounted on the top of the connecting shaft 17. The second clamping block 18 has the same shape as the first clamping block 10. The connecting shaft 17 and the rotating shaft 16 are connected by belt drive. By setting the second clamping block 18, the second clamping block 18 and the first clamping block 10 are located on the same plane. When the second clamping block 18 follows the first clamping block 10 to position the workpiece, the workpiece is aligned under four-point positioning. This setting can further improve the positioning effect of the workpiece.

[0022] A second motor 19 is installed on the front side of the transverse slide table 5. The laser cutter 6 is installed outside the output shaft of the second motor 19. By setting the second motor 19, the laser cutter 6 can be driven to rotate when the second motor 19 is started. This setting can adjust the cutting angle of the cutter, so that the cutter can cut a bevel.

[0023] Scrapers 20 are installed on both the left and right sides of the transverse slide table 5. The scrapers 20 are in contact with the slide rail surface of the cross frame 4. By setting the scrapers 20, the scrapers 20 can scrape the inner wall of the slide rail when the transverse slide table 5 moves, thereby preventing dust generated during cutting from adhering to the slide rail and causing sliding jamming.

[0024] Scrapers 20 are also installed on the front and rear sides of the longitudinal slide table 3 and are attached to the slide rail surface of the longitudinal frame 2. A removable sponge sleeve is fitted on the outside of the scraper 20. The scraper 20 can be easily removed and cleaned by fitting the sponge sleeve on the outside of the scraper 20.
