[0001] The invention relates to the field of pipe cutting, and in particular to a pipe laser cutting processing auxiliary tool. Background Art

[0002] When cutting pipes, laser cutting is often used. It has the advantages of high cutting efficiency and high cutting precision and is widely used in the field of mechanical processing.

[0003] In the laser cutting method, the pipe is first automatically cut, and then the pipe is cut. During cutting, the chuck is used to clamp and fix the pipe, and then the cutter is used to cut the pipe. Using the above laser cutting method, for long pipes, since the pipe is only clamped at the chuck, both ends of the pipe extend out of the chuck, and the cutter is aligned with the predetermined position of one end of the pipe extending out of the chuck.

[0004] During the process of cutting the pipe, the mass distribution of the pipe will change, especially at the end of the pipe. This uneven mass distribution will cause the pipe to swing eccentrically when it rotates under the chuck, affecting the cutting accuracy and processing quality. Summary of the invention

[0005] In order to solve the problem in the prior art that eccentric swing may occur during tube cutting, thus affecting the cutting accuracy, the present application provides a tube laser cutting processing aid.

[0008] A material drop rack, wherein the material drop rack is provided with an inclined surface for sliding down the pipe, and the inclined surface is provided with an opening;

[0009] A mounting plate, the mounting plate is fixedly connected to the blanking rack;

[0010] A material supporting component, the material supporting component is movably connected to the mounting plate, the material supporting component protrudes from the blanking rack through the opening, and the material supporting component is used to support the tube material;

[0011] A moving component is connected to the mounting plate and is used to drive the supporting component to move.

[0012] By adopting the above technical solution, the end of the pipe extending out of the chuck is supported by the supporting component, and the supporting component is driven to move by the moving component, and the supporting component extends from the opening and protrudes out of the blanking rack. By adjusting the height of the supporting component, the part of the pipe supported by the supporting component can be kept in the same height as the part clamped by the chuck, so that the pipe is not easy to swing eccentrically during cutting, and the cutting accuracy is improved. When the cutting is completed, the supporting component is retracted into the drop frame, and the remaining pipes can slide down the inclined surface for easy unified collection.

[0014] By adopting the above technical solution, a supporting wheel with a supporting trough with increasing inner diameter is provided to support the pipe. The inner diameter of the supporting trough can be changed by rotating the supporting shaft, so that the inner diameter matches the diameter of the pipe, making the placement of the pipe more stable.

[0015] Optionally, the supporting component further includes a positioning plate and an indexing pin, wherein the positioning plate is arranged at both ends of the supporting wheel, the positioning plate is provided with a plurality of through holes, and the indexing pin is cooperatively connected to any of the through holes.

[0018] By adopting the above technical solution, the ejecting cylinder pushes the floating joint to move, driving the base and the supporting wheel to move up and down. At this time, the guide rod will slide along the linear bearing, so that the moving direction of the base is further limited.

[0019] Optionally, one end of the guide rod away from the base is connected to a limiting plate, the mounting plate is connected to the limiting rod, and the limiting rod abuts against the limiting plate.

[0029] In summary, this application has the following beneficial effects:

[0030] The end of the pipe extending out of the chuck is supported by the supporting component, which is driven to move by the moving component. The supporting component extends from the opening and protrudes out of the blanking rack. By adjusting the height of the supporting component, the part of the pipe supported by the supporting component can be kept in the same height as the part clamped by the chuck, so that the pipe is not prone to eccentric swing during cutting, and the cutting accuracy is improved. When the cutting is completed, the supporting component retracts into the drop frame, and the remaining pipes can slide down the slope for easy unified collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following is combined with Figure 1-4 This application is described in further detail.

[0038] The present application embodiment discloses a tube laser cutting processing auxiliary tool. Figure 1 A tube laser cutting processing auxiliary tool includes a blanking rack 1, a mounting plate 2, a supporting component and a moving component.

[0039] The outside of the blanking rack 1 is a cabinet, and the inside is hollow and provided with a crossbar. The top surface of the blanking rack 1 is provided with an inclined surface 11, and the inclined surface 11 is provided to facilitate the pipe rack to slide down along the inclined surface 11. An opening 12 is provided on the inclined surface 11, and the opening 12 facilitates the extension of the supporting parts. The four corners of the bottom of the blanking rack 1 are installed with foot cups 13, and the foot cups 13 include a screw and a chassis. The screw is threadedly connected to the chassis, and the foot cups 13 are conveniently adjusted by rotating the thread to change the height of the blanking rack 1. The mounting plate 2 is fixedly connected to the crossbar inside the blanking rack 1, and the mounting plate 2 is fixed to the crossbar through a pad and bolts.

[0040] Reference Figure 2 and Figure 3The supporting component includes a base 3, a supporting shaft 4, a supporting wheel 5, a positioning plate 52 and a dividing pin 41. The supporting component is used to support the pipe extending from the chuck, so that the height of the part of the pipe supported by the supporting component and the part clamped by the chuck are consistent, so that the pipe is not easy to shake during cutting, and the cutting error caused by the eccentric swing of the pipe is effectively reduced. The base 3 includes an adapter plate 31, a fixed plate 32 and a clamp 33. The adapter plate 31 is movably connected to the mounting plate 2. The adapter plate 31 can move up and down toward the mounting plate 2 or away from the mounting plate 2. An anti-collision rubber pad 22 is installed on the mounting plate 2. When the adapter plate 31 moves toward the mounting plate 2, the adapter plate 31 abuts against the anti-collision rubber pad 22 to avoid collision between the adapter plate 31 and the mounting plate 2. The fixed plate 32 is fixedly connected to the adapter plate 31 by bolts, and the clamp 33 is fixedly connected to the fixed plate 32 by bolts.

[0041] The fixing plate 32 and the clamp 33 are provided with a circular hole for accommodating the supporting shaft 4. The supporting shaft 4 is rotatably connected to the fixing plate 32, and the supporting wheel 5 is connected to the supporting shaft 4. The supporting wheel 5 is provided with a supporting groove 51, which is used to support the pipe material. The supporting groove 51 is distributed around the central axis of the supporting shaft 4, and the inner diameter of the supporting groove 51 increases or decreases along the circumferential direction. When the supporting shaft 4 is rotated, the supporting wheel 5 rotates accordingly, so that the inner diameter of the supporting groove 51 changes, which makes it convenient to make the inner diameter of the supporting groove 51 coincide with the diameter of the pipe material, so that the pipe diameter is stably placed on the supporting wheel 5.

[0042] The positioning plate 52 is connected to both ends of the support wheel 5. A plurality of through holes 53 are formed on the circumferential surface of the positioning plate 52. The indexing pin 41 is connected to the fixing plate 32. The indexing pin 41 is inserted into one of the through holes 53 and connected in a matching manner. By setting the positioning plate 52 and the indexing pin 41, the positions of the support wheel 5 and the support shaft 4 can be fixed, so that the inner diameter of the support slot 51 is fixed; when the support slot 51 needs to be adjusted for different pipes, the indexing pin 41 can be taken out and the support shaft 4 can be rotated to achieve the adjustment.

[0043] Reference Figure 2 and Figure 4The moving parts include a feeding cylinder 6, a floating joint 61, a guide rod 71 and a linear bearing 7. The feeding cylinder 6 is connected to the mounting plate 2 through a pad and a bolt. The floating joint 61 is connected to the output end of the feeding cylinder 6. The end of the floating joint 61 away from the feeding cylinder 6 is connected to the adapter plate 31. The output end of the feeding cylinder 6 extends out, driving the base 3 and the supporting wheel 5 to move upward. The supporting wheel 5 extends out of the opening 12 and protrudes out of the blanking rack 1, and supports the pipe through the supporting groove 51. The supporting height is consistent with the height of the chuck, which is convenient for cutting the pipe and improving the cutting accuracy. When the pipe cutting is completed, the output end of the feeding cylinder 6 retracts, driving the supporting wheel 5 to move downward and return to the blanking rack 1. The remaining pipes will reach the inclined surface 11 of the blanking rack 1 and slide down along the inclined surface 11, which is convenient for collecting the remaining pipes.

[0044] The linear bearing 7 is arranged on the mounting plate 2, the guide rod 71 is slidably connected to the linear bearing 7, one end of the guide rod 71 is connected to the adapter plate 31, when the ejection cylinder 6 drives the adapter plate 31 to move, the guide rod 71 simultaneously moves linearly along the linear bearing 7. The movement of the guide rod 71 also limits the moving direction of the base 3, so that the two ends of the base 3 can remain horizontal during the up and down movement.

[0045] The end of the guide rod 71 away from the adapter plate 31 is connected to the limit plate 8. When the guide rod 71 moves up and down along the linear bearing 7, the limit plate 8 moves up and down accordingly. The mounting plate 2 is connected to the limit rod 21, and the limit rod 21 is fixed to the mounting plate 2 by nuts on the upper and lower sides. A rubber pad is installed on the position corresponding to the limit rod 21 on the limit plate 8. When the limit plate 8 moves upward toward the limit rod 21, the rubber pad abuts against the limit rod 21. At this time, the limit plate 8 and the supporting wheel 5 will not be able to continue to move upward. The maximum output stroke of the ejection cylinder 6 is limited by the setting of the limit rod 21 and the limit plate 8.

[0046] One end of the lifting cylinder 6 away from the floating joint 61 is connected to a limiting bracket 9, and the limiting bracket 9 is used to limit the lowest position of the lifting cylinder 6. When the output end of the lifting cylinder 6 retracts, the limiting plate 8 moves downward away from the limiting rod 21. The setting of the limiting bracket 9 ensures that the limiting plate 8 will not rub against the ground when it is at the bottom.

[0047] The implementation principle of a pipe laser cutting processing auxiliary tool in the embodiment of the present application is as follows: when the pipe is cut, the pipe is clamped by the chuck, and both ends of the pipe extend out of the chuck. At this time, the output end of the ejector cylinder 6 extends out, driving the base 3 and the supporting wheel 5 to move upward, and the supporting wheel 5 extends out of the opening 12 and protrudes out of the blanking rack 1 to support the pipe. The supporting shaft 4 is rotated so that the inner diameter of the supporting groove 51 matches the diameter of the pipe, and the indexing pin 41 is inserted to fix the position of the supporting wheel 5, so as to keep the supporting height consistent with the height of the chuck. When the rubber pad of the limit plate 8 is in contact with the limit rod 21, the ejector cylinder 6 reaches the maximum output stroke. When the height still cannot reach the chuck height, the height of the blanking rack 1 can be raised by adjusting the foot cup 13.

[0048] The pipe is held in the supporting trough 51 and then cut by the cutter. When the pipe cutting is completed, the output end of the ejection cylinder 6 retracts, driving the supporting wheel 5 to move downward and return to the blanking rack 1, and the remaining pipe will reach the inclined surface 11 of the blanking rack 1 and slide down along the inclined surface 11, so that the remaining pipe can be collected conveniently.

[0049] This specific implementation manner is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the specific implementation manner as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
