Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to an auxiliary positioning structure for laser cutting. Background Art

[0002] As an important processing method in modern industrial manufacturing, laser cutting technology has been widely used in metal processing, automobile manufacturing, aerospace and other fields with its high precision and high efficiency. However, with the continuous improvement of manufacturing precision and the increasing complexity of processing requirements, higher requirements are put forward for the positioning accuracy and stability in the laser cutting process. In the laser cutting process, the auxiliary positioning structure plays a vital role. It can help the equipment accurately determine the cutting position and ensure the accuracy and consistency of the cutting trajectory.

[0003] When the existing laser cutting machine is cutting, the material needs to be positioned. The existing method is to use a ruler on the workbench for positioning, but there is no fixed part, and the phenomenon of stringing and misalignment often occurs during the cutting process, which seriously affects the cutting quality of the workpiece;

[0004] The existing patent (publication number: CN213888735U) is a positioning structure for a laser cutting machine. This positioning structure for a laser cutting machine is equipped with a manual driving device. Therefore, when the handle is turned, the handle will drive the first bevel gear to rotate through the first connecting shaft, so that the second bevel gear and the third bevel gear drive the first threaded rod and the second threaded rod to rotate through the second connecting shaft and the third connecting shaft. Since the thread directions of the first threaded rod and the second threaded rod are opposite, the two sets of slide rails move relative to each other, so that the fixed block in the slide rail fixes the workpiece, which solves the problem that the workpiece cannot be fixed on traditional laser cutting machines.

[0005] In view of the above problems, existing patents have provided solutions, but there is still the problem that it is not possible to perform multi-point auxiliary positioning of the workpiece to be cut and adjust the different positions of the workpiece for auxiliary positioning. The workpiece will be separated after the laser cutting machine cuts the workpiece, and auxiliary positioning of the workpiece at a single position will cause the workpiece to move during cutting.

[0006] Therefore, an auxiliary positioning structure for laser cutting is proposed. Utility Model Content

[0031] The adjustable multi-point positioning mechanism includes a motion block 51, a bidirectional screw rod 52, a servo motor 53, a mounting frame 54, an electric push rod 55, a push plate 56, a spring 57 and a positioning pressure plate 58.

[0032] Specifically, Figure 4 As shown, the side walls at both ends of the push plate 56 are fixedly connected with fixed cylinders 7 , the side walls of the positioning pressure plate 58 are fixedly connected with guide cylinders 8 , and the guide cylinders 8 are movably connected with the fixed cylinders 7 .

[0033] Specifically, Figure 4 As shown, a T-shaped rod 9 is fixedly connected to the side wall of the positioning pressure plate 58 , and the T-shaped rod 9 is movably connected to the push plate 56 .

[0034] Specifically, Figure 4 As shown, the bottom of the positioning plate 58 is bonded with an anti-skid pad 10 , and the side wall of the anti-skid pad 10 is provided with anti-skid patterns.

[0035] Specifically, Figure 4As shown, two guide rods 11 are fixedly connected to the side walls of the push plate 56 , and guide blocks 12 are welded to both side walls of the mounting frame 54 , and the guide blocks 12 are movably connected to the guide rods 11 .

[0036] Specifically, Figure 1 As shown, a plurality of groups of rollers 16 are arranged in the middle of the cutting table 1 .

[0037] When in use, when assisting in positioning the workpiece, the position of the moving block 3 in the moving frame 2 can be driven by adjusting the driving mechanism 6. When the workpiece is fixed, the electric push rod 55 is started to push the push plate 56 to move downward. The guide rod 11 and the guide block 12 are movably connected to guide the movement of the push plate 56. First, the positioning pressure plate 58 contacts the workpiece. During this process, the anti-slip pad 10 can prevent the positioning pressure plate 58 from sliding against the workpiece. At the same time, the contraction of the spring 57 can prevent the positioning pressure plate 58 from causing extrusion damage to the workpiece. The fixed cylinder 7 and the guide cylinder 8 are movably connected, and the T-shaped rod 9 and the push plate 56 are movably connected to prevent the positioning pressure plate 58 from causing damage to the workpiece. The movement is guided. At this time, multiple positioning plates 58 can perform multi-point positioning on the workpiece. When adjusting the positioning position of workpieces of different sizes, the external power supply is connected to start the servo motor 53. The servo motor 53 drives the bidirectional screw rod 52 to rotate. At this time, the motion block 51 and the bidirectional screw rod 52 are threaded. At this time, the two motion blocks 51 move at the two ends of the bidirectional screw rod 52. At this time, the positioning position of different workpieces can be adjusted. In this way, the workpiece is fixed at multiple points before cutting, and the positioning position of different workpieces can be adjusted according to the size of different workpieces, thereby improving the stability of auxiliary positioning of the workpiece.

[0038] Specifically, Figure 2 As shown, the adjustment drive mechanism 6 includes a bidirectional screw rod 61 and a servo motor 62. The bearing of the bidirectional screw rod 61 is connected to the middle part of the moving frame 2. The bidirectional screw rod 61 is threadedly connected to the moving block 3. The servo motor 62 is bolted to the side wall of the moving frame 2 and the output end is fixedly connected to the bidirectional screw rod 61.

[0039] Specifically, Figure 5 As shown, support parts 13 are provided at both ends of the moving block 3 , balls 14 are embedded at the bottom of the support parts 13 , support grooves 15 are opened on the side walls of the moving frame 2 , and the balls 14 are movably arranged inside the support grooves 15 .

[0040] When in use, connect the external power supply to start the servo motor 2 62 to drive the bidirectional screw rod 2 61 to rotate. At this time, the bidirectional screw rod 2 61 and the moving block 3 move in threaded motion. At this time, the moving block 3 moves in the middle of the moving frame 2. During this process, the ball 14 moves inside the support groove 15, so that the moving frame 4 can be driven to move, and the position of the moving frame 4 on the top surface of the cutting table 1 can be flexibly adjusted, which can assist in adjusting the positioning position of the workpiece, thereby improving the flexibility of positioning the workpiece.

[0041] By adopting the above technical solution, the problem that the existing positioning structure of the laser cutting machine is unable to perform multi-point auxiliary positioning of the workpiece to be cut and adjust the different positions of the workpiece for auxiliary positioning is solved. The workpiece will be separated after the laser cutting machine cuts the workpiece, and auxiliary positioning of the workpiece at a single position will cause the workpiece to move during cutting.

[0042] Working principle: When the present application is used, firstly, when assisting the positioning of the workpiece, the servo motor 2 62 is started by an external power supply to drive the bidirectional screw rod 2 61 to rotate. At this time, the bidirectional screw rod 2 61 and the moving block 3 move in a threaded manner. At this time, the moving block 3 moves in the middle of the moving frame 2. When the workpiece is fixed, the electric push rod 55 is started to push the push plate 56 to move downward. The guide rod 11 and the guide block 12 are movably connected to guide the movement of the push plate 56. First, the positioning pressure plate 58 contacts the workpiece. During this process, the anti-slip pad 10 can prevent the positioning pressure plate 58 from sliding against the workpiece. At the same time, the contraction of the spring 57 can prevent the positioning pressure plate 58 from causing extrusion damage to the workpiece. The fixed cylinder 7 is movably connected to the guide cylinder 8. The T-bar 9 is movably connected to the push plate 56 to guide the movement of the positioning plate 58. At this time, multiple positioning plates 58 can perform multi-point positioning on the workpiece. When adjusting the positioning position of workpieces of different sizes, the external power supply is connected to start the servo motor 53. The servo motor 53 drives the bidirectional screw rod 52 to rotate. At this time, the motion block 51 and the bidirectional screw rod 52 are threaded. At this time, the two motion blocks 51 move at both ends of the bidirectional screw rod 52. At this time, the positioning position of different workpieces can be adjusted. In this way, the workpiece is fixed at multiple points before cutting, and the positioning position of different workpieces can be adjusted according to the sizes of different workpieces, thereby improving the stability of auxiliary positioning of the workpiece.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
