Description

Technical Field

[0001] This utility model relates to the field of laser tube cutting machine technology, and in particular to a high-low track laser tube cutting machine. Background Technology

[0002] Existing laser tube cutting machines have a vertical bed structure with several guide rails installed on the vertical surface of the bed. The chuck is slidably mounted on the guide rails on the vertical surface for movement. The existing side-mounted structure has limitations in stability and insufficient support for cutting large-diameter and long tubes. The side-mounted front chuck generates significant vibration during rotation, affecting cutting accuracy.

[0003] Existing laser tube cutting machines typically have two chucks: a rear chuck for feeding and a front chuck for clamping and rotating the tube for cutting. After cutting, the tube is unloaded via a feeding mechanism. The front chuck is usually fixed to the machine bed and can only process tubes near the laser head, not those further away, and cannot process the tail section of the tube. Furthermore, due to the distance between the front chuck and the feeding mechanism, longer tubes can fall directly onto the feeding mechanism after cutting, but shorter tail sections cannot. A third chuck needs to be added to the machine bed to clamp the cut tail section and move it to the feeding mechanism. Adding a third chuck requires corresponding moving and control mechanisms, making the tube cutting machine more complex and increasing operating costs.

[0004] The existing method of using laser tube cutting machines to process tubes involves feeding the tube into a feeding mechanism while cutting. During the cutting process, the rear chuck feeds the tube, while the front chuck clamps and rotates it, working in conjunction with the laser head for cutting. For longer tubes, the rear chuck can assist the front chuck in clamping, achieving clamping at both ends. For shorter tail sections, the rear chuck cannot continue to clamp and feed the tube, and only the front chuck can clamp it. Existing front chucks typically have two sets of rollers to clamp the tube, but due to the small distance between the two sets of rollers, the front chuck can only support one end of the tail section. The unclamped portion of the tail section will tilt or even fall during processing, which is detrimental to cutting the tail section. Although adding a third chuck can achieve tail section clamping, it would make the overall structure of the laser tube cutting machine more complex and costly, and it is not possible to upgrade from the existing two-chuck tube cutting machine.

The guide rail on the side closer to the sliding device is lower. Therefore, the stability of the rear chuck, front chuck, and follow-up receiving mechanism on the guide rails, as well as the support capacity for cutting large-diameter and long pipes, are all improved. The vibration generated by the front chuck during rotation is smaller, which can improve the cutting accuracy.

[0027] 2. In this utility model, the front chuck of the device can move horizontally on the bed, so that the front chuck can not only process the tube close to the laser head, but also clamp the tube and move it to the other side of the laser head to process the tube away from the laser head, thus realizing the processing operation of the tail of the tail tube.

For shorter tail material tubes, after the front chuck finishes cutting, they can fall directly onto the receiving plate of the follow-up receiving mechanism and complete the unloading. Therefore, it is not necessary to add a third chuck on the bed to clamp the cut tail material and move the cut tail material tube to the unloading mechanism. Attached Figure Description

Detailed Implementation

[0054] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0055] Example: Reference Figure 1-23The high-low track laser tube cutting machine shown includes a bed, which is composed of a first bed body 8 and a second bed body 9. The second bed body 9 is fixedly installed on the left side of the first bed body 8 and is higher than the first bed body 8. A rear chuck 1 is provided on the rear side of the bed body for clamping the tail end of the tube for feeding. A base 10 is installed on the lower part of the bed body, and multiple follow-up support devices 11 are provided on the base 10. The follow-up support devices 11 are located on the right side of the bed body and correspond to the position of the rear chuck 1. The tube is conveyed to the follow-up support devices 11 by a feeding device. 1. The pipe is lifted, and the rear chuck 1 clamps the tail of the pipe for feeding. The machine head structure 5 is set on the front side of the bed. The machine head structure 5 is used to cut the pipe. The front chuck 2 is set on the rear side of the machine head structure 5. The front chuck 2 is used to clamp the pipe for rotation. The follow-up receiving mechanism 3 is set on the front side of the machine head structure 5. The tail material clamping mechanism 6 is set on the front side of the follow-up receiving mechanism 3. The tail material clamping mechanism 6 is used to clamp the tail material pipe held by the front chuck 2. The fixed receiving mechanism 4 is set on the front side of the bed. Both the follow-up receiving mechanism 3 and the fixed receiving mechanism 4 are used to receive the pipe.

[0056] Compared to existing side-mounted pipe cutting machines that set the guide rails on a vertical plane, this device sets both the first guide rail 12 and the second guide rail 13 on a horizontal plane, and the two guide rails are at different heights. The guide rail on the side closer to the sliding device is lower. Therefore, the stability of the rear chuck 1, the front chuck 2, and the follow-up receiving mechanism 3 in this device as they move on the guide rails, as well as their support capacity for cutting large-diameter and long pipes, are all improved. The front chuck 2 generates less vibration during rotation, which can improve the cutting accuracy.

[0057] A first guide rail 12 is installed on the horizontal top surface of the first bed 8, and a second guide rail 13 and a rack 14 are installed on the horizontal top surface of the second bed 9. The rack 14 is located between the first guide rail 12 and the second guide rail 13. A first connecting plate 30 and a second connecting plate 32 are installed between the front chuck 2 and the follow-up receiving mechanism 3. Multiple third sliders 31 adapted to the first guide rail 12 are installed on the first connecting plate 30, and multiple fourth sliders 33 adapted to the second guide rail 13 are installed on the second connecting plate 32. A receiving protective cover 29 is provided between the front chuck 2 and the follow-up receiving mechanism 3 to protect the first guide rail 12, the second guide rail 13 and the rack 14, and prevent the processing debris from falling onto the first guide rail 12, the second guide rail 13 and the rack 14, affecting the movement of the follow-up receiving mechanism 3.

[0058] The rear chuck 1 includes a feeding chuck 101, which is used to clamp the tail end of the pipe for feeding.

[0059] The front chuck 2 includes a clamping chuck 201, which is used to clamp the pipe and rotate it, and works with the head structure 5 to cut the pipe.

[0060] Both the feeding chuck 101 and the clamping chuck 201 are equipped with moving components, which are used to drive the rear chuck 1 and the front chuck 2 to move along the rack 14.

[0061] The moving assembly includes a first sliding seat 19. Multiple first sliders 20, adapted to the second guide rail 13, are mounted on the bottom left side of the first sliding seat 19. A support frame 21 is provided on the bottom right side of the first sliding seat 19. Multiple second sliders 22, adapted to the first guide rail 12, are mounted on the bottom of the support frame 21. A first servo motor 23 is mounted on the upper part of the first sliding seat 19. The first servo motor 23 is connected to a first reducer via a coupling. The output end of the first reducer extends to the lower part of the first sliding seat 19 and is connected to a first gear 24. The first gear 24 meshes with a rack 14. A side bracket 25 is provided on the upper part of the first sliding seat 19. The feeding chuck 101 is installed on the side bracket 25 in the rear chuck 1, and the clamping chuck 201 is installed on the side bracket 25 in the front chuck 2. A backlash adjustment mechanism is provided on the first sliding seat 19. The first gear 24 and the rack 14 need to mesh to drive the rear chuck 1 and the front chuck 2 to move. In the prior art, the meshing degree of the gear and the rack can usually only be guaranteed by the precision of machining. The gear and the rack need to be machined within the tolerance zone, which may result in errors. Moreover, the meshing between the gear and the rack cannot be flexibly adjusted.

[0062] The first servo motor 23 in the rear chuck 1 drives the first gear 24 to move along the rack 14, thereby driving the rear chuck 1 to move horizontally on the bed.

[0063] The first servo motor 23 in the front chuck 2 drives the first gear 24 to move along the rack 14, thereby driving the front chuck 2 to move horizontally on the bed. This allows the front chuck 2 to not only process the pipe close to the head structure 5, but also to clamp the pipe and move it to the other side of the head structure 5 to process the pipe away from the head structure 5, thus realizing the processing of the tail of the tail material pipe.

[0064] The fixed receiving mechanism 4 and the follow-up receiving mechanism 3 are used together to receive and unload long pipes. The second servo motor 38 drives the synchronous lifting and receiving of materials, and the first cylinder 45 drives the receiving plate 44 to flip and unload materials synchronously.

[0065] The backlash adjustment mechanism includes an adjusting seat 26 and a tensioning seat 28. Both the adjusting seat 26 and the tensioning seat 28 are mounted on the upper part of the first sliding seat 19. A gear hole 27 is provided at the center of the adjusting seat 26, and multiple mounting holes are evenly distributed circumferentially around the gear hole 27. The first reducer is fixedly mounted on the adjusting seat 26 by screws and mounting holes. Adjusting holes are provided at the four corners of the adjusting seat 26. The adjusting holes are elongated and their length direction is perpendicular to the length direction of the rack 14. The first sliding seat 19 is provided with four fixing holes, which correspond to the adjusting holes. By screwing the four screws... The screws pass through the adjustment hole and the fixing hole respectively, and the adjustment seat 26 is installed on the first sliding seat 19. Since the adjustment hole is long and narrow, the adjustment seat 26 can move relative to the first sliding seat 19 within a certain length range after it is installed. Two tensioning holes are opened on the side wall of the adjustment seat 26. Both the fixing hole and the tensioning hole are threaded holes. The axis of the tensioning hole is perpendicular to the length direction of the rack 14. The tensioning seat 28 is located between the adjustment seat 26 and the bed. Two positioning holes are opened on the tensioning seat 28. The two positioning holes correspond to the two tensioning holes. Screws are installed in the positioning holes and are threadedly connected to the tensioning holes.

[0066] When the first gear 24 and rack 14 have a certain gap that needs to be adjusted, the screw in the positioning hole is tightened. During the tightening process, the nut of the screw will press against the tensioning seat 28. During the rotation of the screw, the adjusting seat 26 will be pulled. The adjusting seat 26 will gradually move towards the tensioning seat 28, and drive the first gear 24 towards the rack 14, so that the first gear 24 and rack 14 mesh to eliminate the gap between the first gear 24 and rack 14. After the first gear 24 and rack 14 are meshed, the screw tightening can be stopped, thus completing the flexible adjustment of the first gear 24 and rack 14. The backlash adjustment mechanism has a simple structure and can be completed by improving the existing equipment.

[0067] The follow-up receiving mechanism 3 includes a connecting frame 301;

[0068] The fixed receiving mechanism 4 includes a receiving frame 401;

[0069] Both the connecting frame 301 and the receiving frame 401 are equipped with receiving components, which are used to receive the pipe material.

[0070] The receiving assembly includes a frame 34, a connecting frame 301 mounted on the frame 34 in the follow-up receiving mechanism 3, and a receiving frame 401 mounted on the frame 34 in the fixed receiving mechanism 4. A lifting frame 41 is provided on the right side of the frame 34. Multiple third guide rails 43 are provided on the right side wall of the frame 34. Multiple fifth sliders 42 adapted to the third guide rails 43 are installed on the left side of the lifting frame 41. A first lead screw 35 is rotatably mounted on the right side of the frame 34. The lower end of the first lead screw 35 is connected to a first synchronous pulley 36. A motor base 37 is mounted on the frame 34. A second servo motor 38 is mounted on the motor base 37. The second servo motor 38 is connected to a second reducer via a coupling. The output end of the second reducer is connected to a second synchronous pulley 39. The first synchronous pulley 36 and the second synchronous pulley 39 are connected by a synchronous belt. A first screw nut 40 is installed on the screw 35. The first screw nut 40 is fixedly connected to the lifting frame 41. A receiving plate 44 is provided on the upper part of the lifting frame 41. The top of the lifting frame 41 is hinged to the rear part of the receiving plate 44. Two carriers are provided on the right side of the lifting frame 41. Two first cylinders 45 are provided on the right side of the lifting frame 41. The cylinder body of the first cylinder 45 is hinged to the carrier. The piston rod of the first cylinder 45 is hinged to the front part of the receiving plate 44. Multiple rollers 47 are provided on the receiving plate 44. The axis of the rollers 47 is perpendicular to the axis of the pipe. The rollers 47 facilitate the movement of the pipe on the receiving plate 44 and reduce the friction between the pipe and the receiving plate 44. Multiple first nylon plates 46 with triangular cross sections are provided on the receiving plate 44 to limit the pipe and facilitate the receiving plate 44 to unload the pipe.

[0071] When the piston rod of the first cylinder 45 extends outward, the receiving plate 44 is in a horizontal state and can receive materials. When the piston rod of the first cylinder 45 retracts, it drives the receiving plate 44 to flip downward, so that the pipe after receiving materials slides down along the receiving plate 44 for pipe cutting and unloading.

[0072] The second servo motor 38 drives the lifting frame 41 to rise and fall, so that the receiving plate 44 can adjust the receiving height according to the pipes of different diameters, thus playing the role of receiving materials in a follow-up manner.

[0073] The follower receiving mechanism 3 is connected to the front chuck 2 via the first connecting plate 30 and the second connecting plate 32. The follower receiving mechanism 3 can move on the first guide rail 12 and the second guide rail 13 of the bed via the third slider 31 and the fourth slider 33. When the front chuck 2 moves under the drive of the first servo motor 23 on it, it can drive the follower receiving mechanism 3 to move synchronously, so that the follower receiving mechanism 3 can always maintain a fixed distance from the front chuck 2. For shorter tail material tubes, after the front chuck 2 has finished cutting, it can fall directly onto the receiving plate 44 in the front chuck 2 and complete the unloading. Therefore, it is not necessary to add a third chuck on the bed to clamp the cut tail material and move the cut tail material tube to the unloading mechanism.

[0074] The head structure 5 includes a column 501, a second sliding seat 502, and a first cantilever 503. The column 501 is mounted on the bed. Screw assemblies are provided between the column 501 and the second sliding seat 502, and between the second sliding seat 502 and the first cantilever 503. A laser head 504 is fixedly mounted on the right end of the first cantilever 503. The two screw assemblies are used to drive the laser head 504 to move vertically and horizontally.

[0075] The lead screw assembly includes a third servo motor 48, a second lead screw 50, and two fourth guide rails 53. The third servo motor 48 is connected to a third reducer via a coupling. The output end of the third reducer is connected to a first pulley 49. One end of the second lead screw 50 is connected to a second pulley 51. The first pulley 49 and the second pulley 51 are connected by a belt. A second lead screw nut 52 is mounted on the second lead screw 50. Multiple sixth sliders 54 are slidably mounted on the fourth guide rails 53.

[0076] Among them, the third servo motor 48 and the two fourth guide rails 53 in the screw assembly between the column 501 and the second sliding seat 502 are both installed on the column 501, the second screw nut 52 is fixedly connected to the second sliding seat 502, the second screw 50 is rotatably installed on the column 501, and the sixth slider 54 is installed on the second sliding seat 502.

[0077] The second lead screw 50 is driven to rotate by the third servo motor 48, which in turn drives the second sliding seat 502 to rise and fall along the fourth guide rail 53.

[0078] Among them, the third servo motor 48 in the lead screw assembly between the second sliding seat 502 and the first cantilever 503 is installed on the second sliding seat 502, the second lead screw nut 52 is fixedly connected to the first cantilever 503, the second lead screw 50 is rotatably installed on the second sliding seat 502, the sixth slider 54 is installed on the second sliding seat 502, and both fourth guide rails 53 are installed on the first cantilever 503.
