However, existing positioning mechanisms in laser cutting equipment still have certain shortcomings, such as:

[0003] Application CN202221904575.2, entitled "Jig for Laser Cutting," includes a worktable, an angle deflection assembly, and a fixing assembly. The angle deflection assembly is disposed on the worktable, and the fixing assembly is disposed on the angle deflection assembly. The angle deflection assembly includes a turntable, a bracket, and a rod. The top wall of the worktable has a groove, and the side wall of the groove has a slide rail. The turntable is rotatably disposed on the groove. The side wall of the turntable has a convex ring, which slides on the slide rail.

In actual use, the support columns on both sides of this laser cutting fixture can only move synchronously in opposite directions. When the plate needs to be positioned at different center positions, it is not convenient to adjust the support structure on one side. At the same time, when it is necessary to cut the plate at an angle, it is not convenient to adjust the longitudinal angle of the laser cutting fixture, which reduces its practicality.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5 The present invention provides a positioning mechanism for a laser cutting device, comprising a table 1, a distance adjustment mechanism installed inside the table 1, a movable plate 9 symmetrically installed on the top of the distance adjustment mechanism, a limiting groove 2 symmetrically opened inside the table 1, a positioning rod 3 fixedly installed inside the limiting groove 2, a slide seat 4 slidably sleeved on the outer ring of the positioning rod 3, the top of the slide seat 4 fixedly connected to the movable plate 9, and a connecting plate 5 fixedly installed at the bottom of the slide seat 4 on the same side, a first screw 6 threaded through the internal thread of the connecting plate 5, the first screw 6 being symmetrically distributed about the center line of the table 1, a fixing block 7 rotatably connected to the adjacent ends of the first screw 6, a turntable 8 fixedly installed on the outer end of the first screw 6, and the top of the fixing block 7 fixedly connected to the bottom surface of the table 1.

[0028] The design of the above structure allows the first screw 6 to rotate on one side of the fixed block 7 by rotating the single-sided turntable 8 and the first screw 6. When the first screw 6 rotates, it can drive the connecting plate 5 to move. Then, the connecting plate 5 will drive the slide block 4 to slide on the outer ring of the positioning rod 3 inside the limiting groove 2, and can drive the top movable plate 9 to adjust its position. The same steps can be used to adjust the position of the movable plate 9 on the other side, thereby enabling the plate to be positioned and supported at different center positions, improving the versatility of positioning.

[0029] A base plate 10 is fixedly installed on the adjacent side of the movable plate 9. A pressure plate 11 is also movably installed on the adjacent side of the movable plate 9. A lifting and positioning mechanism is connected between the pressure plate 11 and the movable plate 9. The lifting and positioning mechanism includes a slide groove 12 symmetrically opened inside the movable plate 9. A slider 13 is slidably limited inside the slide groove 12. The slider 13 is fixedly connected to the pressure plate 11. A connecting groove 14 is opened in the middle of the movable plate 9. A linkage plate 15 is slidably installed inside the connecting groove 14. A second screw 16 is threaded through the inside of the linkage plate 15. A positioning seat 17 is rotatably sleeved at the bottom end of the second screw 16. The positioning seat 17 is fixedly connected to the movable plate 9.

[0030] The above-described structure allows the plate to be inserted and placed on the top surface of the bottom support plate 10 on both sides after the position of the movable plates 9 on both sides is adjusted. Then, by rotating the second screws 16 on both sides, the second screws 16 can rotate inside the positioning seat 17, and can drive the linkage plate 15 to rise and fall inside the connecting groove 14, thereby driving the pressure plate 11 to rise and fall to squeeze and position the placed plate. The sliding connection between the slider 13 and the slide groove 12 can limit the rise and fall of the pressure plate 11, improving the stability of the rise and fall adjustment work.

[0031] An angle adjustment mechanism is fixedly connected to the bottom of the platform 1. The angle adjustment mechanism includes a rotating seat 18 symmetrically installed on the bottom of the platform 1. A sleeve 19 is fitted around the outer ring of the rotating seat 18. A rotating groove 20 is opened inside the sleeve 19. A groove 21 is opened on the inner side of the rotating seat 18. A protrusion 22 fits inside the groove 21. The protrusion 22 is fixedly connected to the side wall of the rotating groove 20. A base 26 is symmetrically installed at the bottom of the sleeve 19. The angle adjustment mechanism also includes a limiting tube 23 fixedly embedded on the outer side of the rotating seat 18. A locking rod 24 slides through the inside of the limiting tube 23. A spring 25 is fitted around the outer ring of the locking rod 24. The two ends of the spring 25 are fixedly connected to the locking rod 24 and the limiting tube 23, respectively. The locking rod 24 and the limiting tube 23 form a telescopic structure through the spring 25. A locking groove is opened at an equal angle on the outer bottom of the rotating seat 18. The locking rod 24 is movably locked into the locking groove.

[0032] The above-described structure is designed so that by rotating the platform 1, the bottom rotating seat 18 can rotate in the rotating groove 20 inside the sleeve 19. When the sleeve 19 rotates, it will cause the groove 21 to slide on the outside of the protrusion 22 to ensure the stability of the rotation. When the angle adjustment is completed, the spring 25 pulls the locking rod 24 to reset, so that the locking rod 24 extends out of the limiting tube 23 and engages with the corresponding groove at the bottom of the rotating seat 18, thereby realizing the positioning work after the longitudinal angle adjustment.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
