Description

Technical Field

[0001] The invention belongs to the technical field of cutting equipment, and in particular relates to a stably clamped laser cutting equipment. Background Art

[0002] Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, evaporated to form holes, and as the beam moves on the material, the holes continuously form a very narrow slit to complete the cutting of the material. Therefore, compared with traditional cutting methods, the laser cutting method has a smaller gap and can save most of the material. However, according to the definition and analysis of the cutting effect, the cutting effect of the material cut by the laser can be satisfactory and the accuracy is high.

[0003] Existing laser cutting equipment generally consists of two parts: a cutting device and a feeding device. The cutting device is responsible for cutting the pipe, and the feeding device is responsible for feeding the pipe into the cutting device along its axial direction. Specifically, the feeding device is equipped with a tail push chuck, which can slide along the axial direction of the pipe, and a main chuck is installed on the side of the cutting device close to the feeding device. When cutting, the tail push chuck clamps the tail end of the pipe and feeds the pipe into the main chuck along its axial direction. The tail push chuck controls the feeding amount of the pipe, thereby realizing axial control of the cutting point on the surface of the pipe; the main chuck and the tail push chuck are fed to rotate synchronously, thereby realizing circumferential control of the cutting point on the surface of the pipe.

[0004] However, the dual-chuck clamping method has the problem of inconsistent synchronization of the dual chucks, which may cause control errors in the relative circumferential rotation of the pipe, affecting the cutting accuracy, or may cause torsional deformation of the pipe. Summary of the invention

[0005] In order to improve the synchronization of double chuck clamping and enhance the cutting accuracy of workpieces, the present application provides a laser cutting device with stable clamping.

[0006] In order to achieve the above purpose, this application adopts the following technical solutions: A stable clamping laser cutting device comprises a casing, on which a worktable is arranged; a guide mechanism, which is arranged along the length direction of the worktable; a first clamping mechanism, which is arranged on one side of the guide mechanism, and the first clamping mechanism comprises a chuck and a rotating drive member, the chuck is connected to the rotating drive member, and the chuck is driven to rotate by the rotating drive member; a second clamping mechanism, which is arranged on the guide mechanism, the second clamping mechanism moves along the length direction of the worktable, and the workpiece is clamped by the second clamping mechanism for axial movement; and a cutting mechanism, which is arranged between the first clamping mechanism and the second clamping mechanism, the cutting mechanism moves synchronously with the second clamping mechanism, and the cutting mechanism cuts the workpiece.

[0007] By adopting the above device, after the feeding part feeds the pipe into the first clamping mechanism, the clamping part of one end of the pipe facing the second clamping mechanism is exposed for clamping by the second clamping mechanism. After clamping, the axial movement is completed by pulling the pipe, so that the pipe between the first clamping mechanism and the second clamping mechanism enters the working range of the cutting mechanism. When the laser is cutting, the second clamping mechanism releases the pipe, and the cutting mechanism slides on the guide mechanism to realize axial control of the laser cutting point on the surface of the pipe, thereby avoiding the error caused by inconsistent synchronization of the double chucks.

[0011] By adopting the above device, when the claw needs to be adjusted, the limit block is moved. Since both ends of the connecting block are fixedly connected to the limit block and the claw, the movement of the limit block is transmitted to the movement of the claw through the connecting block to adjust the tightness of the claw, which is convenient for adjusting the clamping force of the claw according to the shape and size of the workpiece, thereby expanding the application range of the chuck.

[0012] Optionally, a contact roller is provided at the end of the clamping claw, the end of the contact roller is connected to the clamping claw, a spring telescopic rod is provided inside the clamping claw, and the spring telescopic rod is used to limit the rotation of the contact roller.

[0013] By adopting the above device, when the workpiece passes through the contact roller, there is rolling friction between the contact roller and the workpiece, which reduces the friction on the workpiece and thereby reduces the wear on the workpiece; when the workpiece needs to be fixed, the spring telescopic rod pops out and abuts against the surface of the contact roller to limit the rotation of the contact roller, which can effectively reduce the shaking or deviation of the workpiece during the cutting process and improve the cutting accuracy and stability.

Since the driven gear and the chuck are coaxially arranged, the chuck is driven to rotate by the driven gear, thereby realizing multi-angle rotation of the workpiece, facilitating all-round cutting of the workpiece, and greatly improving the cutting efficiency of the workpiece.

[0016] Optionally, the second clamping mechanism includes a first translation driving member and a clamping member, the first translation driving member is arranged on the guide mechanism, the clamping member is connected to one side of the first translation driving member, and the movement of the clamping member on the guide mechanism is realized by the first translation driving member.

[0022] Optionally, the guiding mechanism includes a first guide rail and a second guide rail, the second guide rail is arranged in the first guide rail, and the first translation driving member is connected to the first guide rail and the second guide rail.

[0023] By adopting the above device, the first translation driving member performs reciprocating motion on the first guide rail and the second guide rail to complete the cutting of the workpiece, thereby maintaining the stability of the first translation driving member during the movement and improving the accuracy of the workpiece cutting.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-9 This application is described in further detail.

[0031] Example: A stable clamping laser cutting device, such as Figure 1 As shown, it includes a housing 1, a cutting mechanism 6, a first clamping mechanism 4 and a second clamping mechanism 5. A workbench 2 is provided on the housing 1, and the first clamping mechanism 4 is fixedly mounted on the workbench 2. A guide mechanism 3 is provided along the length direction of the workbench 2, and the second clamping mechanism 5 and the cutting mechanism 6 are both mounted on the guide mechanism 3 and can move synchronously along the guide mechanism 3. The cutting mechanism 6 is located between the first clamping mechanism 4 and the second clamping mechanism 5, and the cutting mechanism 6 is connected to the second clamping mechanism 5.

[0032] During operation, after the workpiece is fed into the first clamping mechanism 4 through the feeding part, the end of the workpiece facing the second clamping mechanism 5 exposes the clamping part for the second clamping mechanism 5 to clamp. After the clamping is stable, the second clamping mechanism 5 pulls the workpiece to complete the axial sliding, so that the cutting position of the workpiece is facing the cutting mechanism 6. During laser cutting, the second clamping mechanism 5 releases the workpiece, and the cutting mechanism 6 slides on the guide mechanism 3 to achieve axial control of the laser cutting point on the workpiece surface, avoiding the cutting error caused by inconsistent synchronization of the double chucks, which is conducive to improving the cutting accuracy and the workpiece processing quality.

[0033] like Figure 1-2As shown, in this embodiment, a circular feed port 11 is opened on the side wall of the casing 1 near the first clamping mechanism 4, and the feed port 11 and the first clamping mechanism 4 are at the same height, so that the workpiece to be cut can smoothly enter the first clamping mechanism 4 in the casing 1 from the feed port 11, ensuring that the workpiece can be accurately positioned and fixed during the cutting process for laser cutting processing.

[0034] like Figure 3 As shown, in this embodiment, the first clamping mechanism 4 includes a chuck 41 and a rotating drive member 42. Two chucks 41 are provided, and the two chucks 41 are arranged in mirror symmetry, and a bearing seat 43 is arranged between the two chucks 41, and the two chucks 41 are fixed on the workbench 2 through the bearing seat 43. The rotating drive member 42 is connected to the two chucks 41 in transmission, and the two chucks 41 are driven by the rotating drive member 42 to rotate synchronously.

[0035] like Figure 3-4 As shown, in this embodiment, the rotary drive member 42 includes a reduction motor 421, a driving gear 422 and a driven gear 423. The driving gear 422 is connected to the output shaft of the reduction motor 421, and the driven gear 423 is meshed with the driving gear 422, and the driven gear 423 is coaxially arranged with the two chucks 41. In addition, the diameter of the driving gear 422 is smaller than the diameter of the driven gear, and the reduction motor 421 drives the driven gear 423 with a larger diameter through the driving gear 422 with a smaller diameter to achieve a reduction effect.

[0036] During operation, the reduction motor 421 drives the driving gear 422 to rotate, and the driven gear 423 drives the chuck 41 to rotate synchronously under the drive of the driving gear 422, so as to realize the rotation of the workpiece, facilitate the multi-angle cutting of the workpiece or the cutting of complex patterns on the workpiece, thereby improving the diversity and flexibility of workpiece processing.

[0037] like Figure 5 As shown, the chuck 41 includes a first slide groove 411, a clamping claw 412 and an adjusting member 413. Among them, there are four clamping claws 412, which are divided into two groups, upper and lower and left and right, to clamp the workpiece from four directions, and four first slide grooves 411 are correspondingly provided, and the clamping claw 412 is slidably connected in the first slide groove 411. The adjusting member 413 is located on one side of the clamping claw 412, and the clamping force of the clamping claw 412 on the workpiece is adjusted by the adjusting member 413, so that the clamping force is kept within a suitable range, so as to ensure that the clamping claw 412 will not damage the workpiece while stably clamping the workpiece.

[0038] like Figure 5As shown, in this embodiment, the adjusting member 413 includes a limit block 413a and a second slide groove 413b. The second slide groove 413b is fixedly mounted on the chuck 41, and the limit block 413a is slidably connected in the second slide groove 413b. An L-shaped connecting block 414 is provided between the limit block 413a and the claw 412. The connecting block 414 is fixedly connected to the claw 412 by bolts and welded to the limit block 413a, so as to realize the synchronous movement of the claw 412 and the limit block 413a through the connecting block 414, thereby clamping and fixing the workpiece. At the same time, by adjusting the claw 412, it can flexibly adapt to workpieces of different sizes and shapes, thereby improving the clamping stability and reliability of the equipment for the workpiece. In addition, a bolt is threadedly connected to the limit block 413a. When the claw 412 is moved and adjusted to a suitable position, the limit block 413a will no longer move by tightening the bolt, but will be fixed in the second slide groove 413b, thereby fixing the position of the claw 412 to maintain the stability of the claw 412 during the cutting process, reduce the slight movement of the claw 412 due to vibration, and ensure the accuracy of workpiece cutting.

[0039] In addition, if Figure 6 As shown, in order to further improve the stability of the workpiece during the cutting process, spring telescopic rods 415 are provided in the clamping claws 412 located at the upper and lower sides, and the ends of the clamping claws 412 are rotatably connected to the contact rollers 412a. Since the workpiece is in rolling friction with the contact rollers 412a when passing through the clamping claws 412, the rotation of the contact rollers 412a is limited by the spring telescopic rods 415 to fix the position of the workpiece, which can effectively reduce the shaking or deviation of the workpiece during the cutting process, and further improve the accuracy and stability of the cutting.

[0040] like Figure 1 As shown, in this embodiment, the guide mechanism 3 includes a first guide rail 31 and a second guide rail 32, and the first guide rail 31 and the second guide rail 32 are both fixed on the workbench 2. There are two first guide rails 31, and the second guide rail 32 is located between the two first guide rails 31, and the second guide rail 32 is rack-shaped.

[0041] like Figure 1 and 7As shown, the second clamping mechanism 5 includes a first translation driving member 51 and a clamping member 52. A rectangular mounting plate 53 is fixedly connected between the clamping member 52 and the bottom of the first translation driving member 51. Four sliders 54 are arranged at the bottom of the mounting plate 53. The four sliders 54 are respectively located at the corners of the mounting plate 53, and the sliders 54 are slidably connected with the first guide rail 31. The first translation driving member 51 includes a driving motor 511 and a running wheel 512. The driving motor 511 is located above the mounting plate 53, and the running wheel 512 is located below the mounting plate 53. The running wheel 512 is connected to the output shaft of the driving motor 511, and the running wheel 512 is meshed with the second guide rail 32. In this embodiment, the running wheel 512 is selected as a helical gear.

[0042] like Figure 7-8 As shown, in this embodiment, in order to further improve the stability of workpiece clamping, the clamping member 52 includes a first clamping jaw 521, a second clamping jaw 522 and a driving cylinder 523. Among them, the end of the first clamping jaw 521 is fixedly connected with a first rack 524, and the output shaft of the driving cylinder 523 is connected to the end of the first clamping jaw 521, and the end of the second clamping jaw 522 is connected with a second rack 525, and a linkage wheel 526 is arranged between the first rack 524 and the second rack 525, and the second rack 525 is transmission-connected to the first rack 524 through the linkage wheel 526. Among them, in this embodiment, the linkage wheel 526 is selected as a gear.

[0043] When the workpiece needs to be clamped, the driving cylinder 523 pushes the first clamping jaw 521 to move, and the first rack 524 fixedly connected to the end of the first clamping jaw 521 moves synchronously. Since the second rack 525 is connected to the first rack 524 through the linkage wheel 526, the second rack 525 is driven to move, and the second rack 525 is fixedly connected to the end of the second clamping jaw 522, and the second rack 525 is driven to move, thereby realizing the distance adjustment between the first clamping jaw 521 and the second clamping jaw 522 to adapt to workpieces of different sizes and shapes, and ensure firm clamping, and ensure the stability and accuracy of the workpiece during the cutting process. At the same time, through the mutual cooperation of the first clamping jaw 521, the second clamping jaw 522 and the clamping jaw 412, the workpiece is fixed at both ends of the cutting area, the position of the workpiece during the cutting process is controlled, and the problem of cutting error or damage to the workpiece is reduced, which is conducive to further improving the stability of workpiece processing and ensuring the processing accuracy of the workpiece. The opposite side of the first clamping jaw 521 and the second clamping jaw 522 is a threaded surface to increase the friction between the first clamping jaw 521, the second clamping jaw 522 and the workpiece, so that the first clamping jaw 521 and the second clamping jaw 522 can clamp the workpiece more firmly and reduce the sliding or displacement of the workpiece, which helps to ensure that the first clamping jaw 521 and the second clamping jaw 522 can firmly maintain the clamping of the workpiece during the operation process, further improving the clamping effect and stability.

[0044] like Figure 1 , 8 As shown in Figures 9 and 10, in this embodiment, the cutting mechanism 6 is located between the first clamping mechanism 4 and the second clamping mechanism 5, and is connected to the second clamping mechanism 5. The cutting mechanism 6 includes a second translation driving member 61 and a cutting head. The second translation driving member 61 is mounted on the mounting plate 53, and the cutting head is connected to one side of the second translation driving member 61. The second translation driving member 61 drives the cutting head to move along the width direction of the workbench 2, thereby achieving continuous, efficient, and high-precision cutting of the workpiece, improving production efficiency and reducing costs.

[0045] In addition, in order to reduce the impact of the second clamping mechanism 5 and the cutting mechanism 6 on the first guide rail 31 during movement, buffer members 33 are provided at both ends of the first guide rail 31. Through the buffering effect of the buffer members 33, the collision between the second clamping mechanism 5 and the cutting mechanism 6 and the casing 1 during movement can be reduced, thereby effectively protecting the second clamping mechanism 5 and the cutting mechanism 6 to extend the service life of the equipment.

[0046] Working principle: The loading part puts the workpiece into the first clamping mechanism 4 from the feed port 11, and clamps one end of the workpiece through the claw 412 on the first clamping mechanism 4. At the same time, the end of the workpiece facing the second clamping mechanism 5 exposes the clamping part for the second clamping mechanism 5 to clamp. After clamping, the workpiece is pulled to complete the axial sliding, so that the workpiece between the first clamping mechanism 4 and the second clamping mechanism 5 is facing the working area of ​​the cutting mechanism 6. When laser cutting is performed, the second clamping mechanism 5 releases the workpiece, and the cutting mechanism 6 moves along the guide mechanism 3 to achieve axial cutting of the laser cutting point on the workpiece surface.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
