Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically to a clamping component for a laser cutting machine. Background Technology

[0002] A laser cutting machine is a device that uses a laser emitted from a laser source to focus a high-power-density laser beam through an optical path system. The laser beam then irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting. When processing a workpiece with a laser cutting machine, it is generally necessary to use a clamping device to fix the workpiece in place to prevent it from shaking during processing.

[0003] Existing clamping components typically use simple clamping mechanisms to hold and fix the workpiece to be cut, and then the cutting machine is moved to perform the cutting process. The clamping part is fixed, and multiple clamping and fixing are required when cutting round and square tubes into sections, which is not conducive to the transportation of the workpiece to be cut and the section cutting, and reduces the efficiency of the laser cutting machine.

[0004] According to CN220050449U, a round tube clamping assembly in a laser cutting machine includes a worktable and further includes: a driving mechanism located on the upper surface of the worktable; a fixing mechanism disposed on the driving mechanism and movable along the length direction of the fixing mechanism, the fixing mechanism being used to support and fix the bottom of the round tube; and a clamping mechanism disposed on the driving mechanism and movable along the length direction of the driving mechanism, the clamping mechanism being used to clamp the side of the round tube.

[0005] The above-described cylindrical tube clamping component in a laser cutting machine suffers from the problem that a single workpiece needs to be clamped and positioned multiple times for segmented cutting. Therefore, we need to propose a clamping component for a laser cutting machine. Utility Model Content

[0006] The purpose of this invention is to provide a clamping assembly for a laser cutting machine. Through the arrangement of the conveying assembly and the clamping mechanism, the workpiece to be cut is placed on the roller in the middle of the rotating rod. By activating two sets of first electric push rods, the distance between the two sets of clamping plates is shortened, causing the auxiliary rollers on opposite sides of the two sets of clamping plates to clamp the workpiece on both sides, forming a triangular clamp with the bottom roller. This achieves the effect of clamping and fixing the middle of a regular, long workpiece. Since both the auxiliary rollers and the roller are rotatable, rotating the rotating rod drives the roller to rotate, and the roller moves the workpiece. This achieves clamping and fixing without affecting the conveying and movement of the workpiece, allowing the workpiece to be cut in sections to move to the bottom of the cutting assembly. After cutting, the rotating rod continues to rotate, moving the next section cutting position to the bottom of the cutting assembly, thus achieving rapid section cutting and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a clamping assembly for a laser cutting machine, comprising a base, a conveying assembly and a cutting assembly mounted on the top of the base, a clamping mechanism mounted inside the conveying assembly, and a workpiece to be cut mounted inside both the conveying assembly and the clamping mechanism. The conveying assembly includes a support frame fixedly mounted on the top of the base, three sets of rotating rods rotatably mounted through the inner side of the support frame, and a set of rollers fixedly fitted in the middle of each of the three sets of rotating rods. The clamping mechanism includes two sets of first electric push rods symmetrically bolted to the inner wall of the support frame, a clamping plate fixedly mounted at one end of each of the two sets of first electric push rods, and two sets of support plates fixedly mounted on opposite sides of each of the two sets of clamping plates. An auxiliary roller is rotatably mounted through the inner side of each pair of support plates.

[0008] Preferably, a motor is bolted to the outside of the support frame, and the output shaft of the motor is keyed to one end of a set of rotating rods in the middle.

[0009] Preferably, one end of the middle set of rotating rods is fixedly fitted with two sets of driving wheels, and one end of the other two sets of rotating rods is fixedly fitted with a set of driven wheels. The outer sides of the two sets of driving wheels are respectively connected to the outer sides of the two sets of driven wheels via belt drive.

[0010] Preferably, the opposing surfaces of the two sets of clamping plates are arranged at an angle, so that the auxiliary rollers generate a downward clamping force on both sides of the workpiece, and the bottom of the workpiece is placed on the top of the rollers.

[0011] Preferably, the two sets of clamping plates are located directly above the middle set of rotating rods, and the bottom of the two sets of clamping plates are movably attached to the top of the middle set of rollers.

[0012] Preferably, the cutting assembly includes an electric slide fixedly mounted on the top of the base, a lifting plate installed on one side of the electric slide, a sliding groove through the top of the lifting plate, a slider slidably mounted inside the sliding groove via a fixed rod, and a laser installed at the bottom of the slider.

[0013] Preferably, a second electric push rod is bolted to the bottom of the lifting plate, and one end of the second electric push rod is fixedly connected to one side of the slider.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes a conveying assembly with rotating auxiliary rollers and clamping rollers. By rotating a rotating rod, the rollers rotate, and the rollers move the workpiece. This achieves clamping and fixing without affecting the conveying and movement of the workpiece, thereby enabling rapid segmented cutting and improving the efficiency of the laser cutting machine.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figure 1-5 This utility model provides a clamping assembly for a laser cutting machine, including a base 1. A conveying assembly 2 and a cutting assembly 4 are installed on the top of the base 1. A clamping mechanism 3 is installed inside the conveying assembly 2. The workpiece 5 to be cut is installed inside both the conveying assembly 2 and the clamping mechanism 3. The conveying assembly 2 includes a support frame 21 fixedly installed on the top of the base 1. Three sets of rotating rods 22 are rotatably installed through the inner side of the support frame 21. A set of rollers 23 is fixedly fitted in the middle of each of the three sets of rotating rods 22. The clamping mechanism 3 includes two sets of first electric push rods 31 symmetrically bolted to the inner side wall of the support frame 21. A clamping plate 32 is fixedly installed at one end of each of the two sets of first electric push rods 31. Two sets of support plates 33 are fixedly installed on the opposite sides of each of the two sets of clamping plates 32. An auxiliary roller 34 is rotatably installed through the inner side of each pair of support plates 33.

[0025] In use, the workpiece 5 to be cut is placed on the roller 23 in the middle of the rotating rod 22. By activating the two sets of first electric push rods 31, the distance between the two sets of clamping plates 32 is shortened, so that the auxiliary rollers 34 on the opposite sides of the two sets of clamping plates 32 clamp the two sides of the workpiece 5, forming a triangular clamp with the bottom roller 23, thereby achieving the effect of clamping and fixing the middle of the regular long workpiece 5. Since both the auxiliary rollers 34 and the rollers 23 are rotating, rotating the rotating rod 22 drives the rollers 23 to rotate, and the rollers 23 drive the workpiece 5 to move. This achieves clamping and fixing without affecting the conveying and movement of the workpiece 5, so that the position of the workpiece 5 to be cut in sections is moved to the bottom of the cutting assembly 4. After adjusting the position of the cutting assembly 4 and starting the cutting, the rotating rod 22 is rotated again to move the next section cutting position to the bottom of the cutting assembly 4, thereby achieving the effect of rapid section cutting.

[0026] A motor 24 is bolted to the outside of the support frame 21. The output shaft of the motor 24 is keyed to one end of the middle set of rotating rods 22. Through the connection between the motor 24 and the rotating rods 22, the motor 24 is started to drive the middle set of rotating rods 22 to rotate stably inside the support frame 21. At the same time, the top of the roller 23 is pressed against the bottom of the workpiece 5. As the roller 23 rotates, it drives the workpiece 5 to move, thereby achieving the effect of automatically conveying the workpiece 5 to the bottom of the cutting component 4.

[0027] Two sets of driving wheels 25 are fixedly mounted on the outer arc surface of one end of the middle set of rotating rods 22. A set of driven wheels 26 is fixedly mounted on one end of each of the other two sets of rotating rods 22. The outer sides of the two sets of driving wheels 25 are respectively connected to the outer sides of the two sets of driven wheels 26 via belts 27. Through the connection relationship between the three sets of rotating rods 22, the two sets of driving wheels 25, the two sets of driven wheels 26, and the two sets of belts 27, rotating the middle set of rotating rods 22 drives the two sets of driving wheels 25 to rotate at the same time. The two sets of driving wheels 25 drive the other driven wheel 26 to rotate via belts 27 at the same time. The two sets of driven wheels 26 drive the rotating rods 22 to rotate, thereby achieving the effect of driving the other two sets of rotating rods 22 to rotate synchronously while one set of rotating rods 22 rotates, which improves the stability of workpiece 5 conveying.

[0028] The two sets of clamping plates 32 are inclined to each other, so that the auxiliary rollers 34 exert a downward clamping force on both sides of the workpiece 5. The bottom of the workpiece 5 is placed on the top of the roller 23. The two sets of clamping plates 32 are located directly above the middle set of rotating rods 22, and the bottom of the two sets of clamping plates 32 is in contact with the top of the middle set of rollers 23. By setting the two sets of clamping plates 32 downward at an incline, the auxiliary rollers 34 and rollers 23 form a stable triangular clamping of the workpiece 5, which is more stable than the traditional two-sided clamping. The two sets of clamping plates 32 are located on the top of the middle set of rollers 23 to prevent the clamping stability from being reduced due to the bending deformation of the middle part of the workpiece 5. At the same time, the bottom of the clamping plates 32 is in contact with the top of the rollers 23 to prevent the workpiece 5 from falling out of the gap between the clamping plates 32 and the rollers 23 due to its small diameter.

[0029] The cutting assembly 4 includes an electric slide table 41 fixedly installed on the top of the base 1. A lifting plate 42 is installed on one side of the electric slide table 41. A sliding groove 43 is opened through the top of the lifting plate 42. A slider 45 is slidably installed inside the sliding groove 43 through a fixed rod 44. A laser 46 is installed at the bottom of the slider 45. A second electric push rod 47 is bolted to the bottom of the lifting plate 42. One end of the second electric push rod 47 is fixedly connected to one side of the slider 45. When the electric slide table 41 is activated, the lifting plate 42 moves up and down, thereby achieving the effect of adjusting the height of the laser 46. When the second electric push rod 47 is activated, the slider 45 slides on the outer arc surface of the fixed rod 44 inside the sliding groove 43, indirectly driving the laser 46 to move, thereby achieving the effect of cutting and trimming the workpiece 5.

[0030] In practical use: First, place one end of the workpiece 5 to be processed on top of the three sets of rollers 23. Start the two sets of first electric push rods 31 to move the two sets of clamping plates 32 closer together or further apart. By shortening the distance between the two sets of clamping plates 32, the auxiliary rollers 34 mounted on opposite sides of the two sets of clamping plates 32 generate a downward clamping force on both sides of the workpiece 5. This, combined with the upward pushing force generated by the rollers 23 on the workpiece 5, forms a triangular clamping force, achieving the effect of clamping and fixing the workpiece 5. Start the motor 24 to drive the three sets of rotating rods 22 simultaneously... As the rotating rod 22 rotates, it drives the roller 23 to rotate. As the roller 23 rotates, it moves and conveys the workpiece 5. The auxiliary roller 34 follows the rotation, but the clamping force of the roller 23 and the auxiliary roller 34 on the workpiece 5 remains unchanged. When the conveying stops, the workpiece 5 remains clamped and fixed, which does not affect the laser cutting. After the laser 46 is started to cut a section of the workpiece 5, the workpiece 5 continues to be conveyed to the next cutting position, thereby achieving the effect of rapid segmented cutting of the workpiece 5 and avoiding the tedious process of clamping and fixing multiple times.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
