Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a laser cutting machine with an automatic feeding structure. Background Art

[0002] The laser cutting machine focuses the laser light emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting.

[0003] The patent document with application number 202222669836.3 discloses a feeding structure of an automatic feeding laser cutting machine, including a machine platform arranged on one side of the laser cutting machine, and a feeding assembly, a branch pipe assembly, a lifting assembly and a conveying assembly arranged on the machine platform in sequence with respect to the conveying direction, characterized in that the feeding assembly forms a feeding part on the machine platform, the lifting assembly includes a first lifting platform, a slide table, and a second lifting platform, and the first lifting platform, the slide table, and the second lifting platform all have a stroke along the conveying direction, the first lifting platform is connected to the feeding part, and the second lifting platform is connected to the conveying assembly, and the pipe slides in stages along the first lifting platform, the slide table and the second lifting platform to the conveying assembly.

[0004] However, in the process of automatic loading, traditional laser cutting machines with automatic loading structures often need to customize new limit clamps according to production needs due to the inconsistent sizes of different workpieces, which increases the factory's production costs and the frequency of fixture replacement. In addition, fixed-model limit clamps may not be able to stably fix the workpiece, which may cause the workpiece to shift or shake during transportation and cutting, which not only affects the cutting accuracy, but also affects the production quality of the workpiece. Utility Model Content

[0005] The utility model discloses a laser cutting machine with an automatic feeding structure, which aims to solve the technical problem that in the automatic feeding process of a traditional laser cutting machine with an automatic feeding structure, due to the inconsistent sizes of different workpieces, new limit clamps are often customized according to production needs, which increases the production cost of the factory and the frequency of fixture replacement, and the limit clamps of fixed models may not be able to stably fix the workpiece, which may cause the workpiece to shift or shake during transportation and cutting, which not only affects the cutting accuracy, but also affects the production quality of the workpiece.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A laser cutting machine with an automatic feeding structure comprises a laser cutting machine body, wherein support columns are arranged near four corners of the bottom of the laser cutting machine body, and further comprises:

[0008] The first limiting mechanism is located on an outer wall of one side of the laser cutting machine body;

[0009] The second limiting mechanism: located on the outer wall on the opposite side of the laser cutting machine body, the second limiting mechanism includes two electric telescopic rods and two clamping plates, the movable end of the electric telescopic rod is provided with a push plate, the outer wall on the opposite side of the push plate is provided with a mounting groove, the two ends of the clamping plate are respectively slidably connected to the inner walls of the two mounting grooves, the outer wall on the side of the clamping plate close to the push plate is provided with seven equidistantly distributed mounting rods and a limiting spring, the limiting spring is wound around the circumferential outer wall of the mounting rod, and the end of the limiting spring away from the clamping plate is welded to the outer wall on one side of the push plate, the outer wall on one side of the push plate is provided with seven equidistantly distributed limiting grooves, the mounting rod is plugged into the inner wall of the limiting groove, and a number of ball bearings are installed on the outer walls on the opposite side of the two clamping plates;

The output shafts of the two first motors drive the threaded rod to rotate. With the cooperation of the limit rod, the connecting block moves up and down on the outer wall of the threaded rod. According to the actual width of the workpiece, the distance between the first connecting rod and the second connecting rod is adjusted, thereby adjusting the distance between the two limit clamps, so that the limit clamps limit the two corners of the workpiece, and then limit and fix one end of the workpiece, thereby improving the practical effect of the device.

[0026] The utility model discloses a laser cutting machine with an automatic feeding structure which is mainly used in scenarios where a traditional laser cutting machine with an automatic feeding structure has, during the automatic feeding process, a new limit clamp is often customized according to production requirements due to the inconsistent sizes of different workpieces, which increases the production cost of the factory and the frequency of fixture replacement, and a fixed-type limit clamp may not be able to stably fix the workpiece, which may cause the workpiece to shift or shake during transportation and cutting, which not only affects the cutting accuracy, but also affects the production quality of the workpiece.

[0030] Adjustment mechanism: located on the top of the laser cutting machine body 1.

[0031] Among them, both the push plate 10 and the clamping plate 14 are of "concave" structure, which makes it easy for the push plate 10 and the clamping plate 14 to be used in coordination, thereby enhancing the practicability of the device.

[0032] During specific use, two mounting rollers are provided on the outer walls of the opposite sides of the laser cutting machine body 1, and the outer walls of the two mounting rollers are sleeved with a conveyor belt 19. A second motor is provided at one end of one of the mounting rollers.

[0033] Specifically, the workpiece to be cut is first placed in the laser cutting machine body 1, and one end of the workpiece is fixed by the second limit mechanism. Before cutting the workpiece, the clamping plate 14 and the push plate 10 are kept at a certain distance by the cooperation of the limit spring 20. When the workpiece needs to be cut, the two electric telescopic rods 18 are started at the same time. Under the push of the movable end of the electric telescopic rod 18, the two push plates 10 approach each other to the two sides of the workpiece. When the clamping plate 14 contacts the two sides of the workpiece, the push plate 10 will continue to move and squeeze the limit spring 20. The squeezing force between the ball 21 and the workpiece plays a certain buffering role in the compression of the limit spring 20.

[0035] The limiting clamping plate 13 is an "L"-shaped structure, which is convenient for limiting the two corner positions at one end of the workpiece.

[0036] In specific use, the length of the second connecting rod 12 is greater than the length of the first connecting rod 11 .

[0037] Specifically, when in use, first put the workpiece in from one side of the feed table, and then start the two first motors 4 at the same time. The output shafts of the two first motors 4 drive the threaded rod 6 to rotate. With the cooperation of the limiting rod 7, the connecting block 8 moves up and down on the outer wall of the threaded rod 6. According to the actual width of the workpiece, the distance between the first connecting rod 11 and the second connecting rod 12 is adjusted, thereby adjusting the distance between the two limiting clamps 13, so that the limiting clamps 13 limit the two corners of the workpiece, and then limit and fix one end of the workpiece, thereby improving the practical effect of the device.

[0038] Reference Figure 1 and Figure 3 In a preferred embodiment, the adjustment mechanism includes a fixed plate 17, a cutting device 16 is provided on the top of the fixed plate 17, two connecting plates 15 are provided on the top outer wall of the laser cutting machine body 1 near the outer walls on both sides, a connecting groove is provided on the top outer wall of the connecting plate 15, and the two ends of the fixed plate 17 are respectively slidably connected to the inner walls of the two connecting grooves, four fixing rods are provided on the top outer wall of the laser cutting machine body 1 near the four corners, and a ruler is provided at one end of two adjacent fixing rods.

[0039] The height of the fixed plate 17 is the same as the height of the ruler, which is convenient for the operator to observe the moving distance of the fixed plate 17 and adjust it accurately, thereby improving the control of the cutting length of the workpiece by the cutting equipment 16.

[0040] Specifically, during use, according to actual production needs, by using the provided ruler in conjunction with the fixed rod, the operator pushes the fixed plate 17 to slide in the connecting groove, thereby driving the cutting device 16 to move to a specified position inside the laser cutting machine body 1, and using the cutting device 16 to cut the moving workpiece, thereby improving the use effect of the device, and flexibly adjusting according to production needs to ensure that the cutting device 16 can cut different positions of the workpiece.

[0041] Working principle: first place the workpiece to be cut in the laser cutting machine body 1, and one end of the workpiece is fixed by the second limit mechanism. Before cutting the workpiece, the clamping plate 14 and the push plate 10 are kept at a certain distance through the cooperation of the limit spring 20. When the workpiece needs to be cut, the two electric telescopic rods 18 are started at the same time. Under the push of the movable end of the electric telescopic rod 18, the two push plates 10 approach each other to the two sides of the workpiece. When the clamping plate 14 hits the two sides of the workpiece, the push plate 10 will continue to move and squeeze the limit spring 20. The squeezing force between the ball 21 and the workpiece plays a certain buffering role in the compression of the limit spring 20. The combination of the mounting rod 5 and the limiting groove guides the movement of the clamp 14. At the same time, the outer wall of the mounting rod 5 is used in combination with the limiting spring 20 to reduce the possibility of bending and deformation of the limiting spring 20. After the workpiece is limited, the conveyor belt 19 is used to move the workpiece to the specified cutting position for cutting.
