Description

Technical Field

[0001] The present invention relates to the technical field of alloy cutting, and specifically to an adaptive cutting device for processing alloy special-shaped parts. Background Art

[0002] Laser cutting uses a high-energy laser beam to precisely cut alloy materials. The laser beam is focused on the surface of the alloy material, causing it to quickly heat up to the melting point or boiling point, and then melting, vaporizing, or burning the material to complete the cutting process. Laser cutting can meet the processing requirements of complex shapes and high-quality requirements. Before cutting some special-shaped workpieces, the workpieces to be processed are also in relatively irregular shapes, and it is not easy to limit and cut the special-shaped workpieces to be processed.

[0003] For example, the patent with the publication number CN220943716U discloses a device for laser cutting alloys. The device for laser cutting alloys includes a loading component, a sliding component, a laser component, and a preheating component. The loading component includes a loading table and a plurality of support columns. The small and equal-height support columns are arranged on the top of the loading table in an array manner, so that the device for laser cutting alloys will not damage the loading table during cutting. The loading component can carry the sliding component, the laser component, and the preheating component, and enables the laser component and the preheating component to move spatially under the action of the sliding component, so that the alloy can be cut and preheated by the laser component and the preheating component. At the same time, the laser component has an air-cooling member, and the air-cooling member can blow out inert gas after cutting to accelerate the cooling of the alloy.

[0004] For example, the patent with the publication number CN114406503B discloses a laser cutting device for titanium alloy plates used in aerospace. It includes a laser cutter fixedly connected to a support frame. Two feeding platforms are symmetrically arranged on both sides of the laser cutter, and a cutting channel is formed between the two feeding platforms. The laser cutter is erected above the cutting channel. The pressing mechanism includes a lift fixed on the feeding platform. The lift has a slider, a connecting frame is connected to the slider and an upper pressing plate, side plates are vertically fixed on both sides of the upper pressing plate, and an upper pressing seat is fixed between the two side plates. The output end of the first conveying motor is connected to the rotating shaft of the first conveyor belt through a sprocket group. The feeding platform and the pressing mechanism cooperate to continuously clamp the titanium alloy plate during the process of conveying the titanium alloy plate. The titanium alloy plate is cut when it moves below the laser cutting head, and after cutting, it continues to be clamped and conveyed by the feeding platform and the pressing mechanism. Due to the complex shape of special-shaped workpieces, the clamping stability is poor, and they are prone to displacement or vibration during the processing. During laser cutting, problems such as cutting burrs and dimensional deviations may occur, resulting in a decrease in processing accuracy and surface quality. In addition, the poor clamping stability of special-shaped workpieces will lead to frequent adjustment of jigs or repositioning of workpieces during the processing, increasing the processing time and the difficulty of cutting operations.

[0005] In view of the above problems, it is urgent to innovate and design on the basis of the original alloy cutting device. Summary of the Invention

[0006] The purpose of the present invention is to provide an adaptive cutting device for processing alloy special-shaped parts, so as to solve the problems proposed in the above background technology. Due to the complex shape of the special-shaped workpiece, the clamping stability is poor, and it is easy to shift or vibrate during the processing. During laser cutting, problems such as cutting burrs and dimensional deviations may occur, resulting in a decrease in processing accuracy and surface quality.

[0007] To achieve the above purpose, the present invention provides the following technical solution: An adaptive cutting device for processing alloy special-shaped parts, including a workbench for cutting and processing alloy parts. An electric slide rail is fixedly installed on the workbench, and a slide seat is slidably installed on the electric slide rail. A gantry is fixedly installed on the upper end surface of the slide seat. A moving frame is horizontally slidably connected to the gantry, and a lifting frame is vertically slidably connected to the moving frame. A laser cutting head is installed on the lifting frame. A fixed disk seat is fixedly installed on the workbench. Along the moving direction of the moving frame on the fixed disk seat, there is a main clamping mechanism for directionally limiting the cutting and processing position of the alloy part, and along the moving direction of the slide seat on the fixed disk seat, there is a secondary clamping mechanism for steering and limiting the cutting and processing position of the alloy part.

[0008] Preferably, the main clamping mechanism includes two groups of main guides fixedly installed on the workbench. A main guide rod is slidably connected through the main guides, and a main fixer is fixedly installed on the main guide rod. The main guide rod is connected through the fixed disk seat.

[0009] Preferably, a bidirectional lead screw is rotatably connected to the workbench, and an internally threaded moving block is sleeved on the bidirectional lead screw. The internally threaded moving block is fixedly connected to the main guide rod.

[0010] Preferably, an air pipe is connected through the main guide rod, and the port of the air pipe is connected to a spray head. The spray head is rotatably installed on the main fixer. A scroll spring is elastically connected between the air pipe and the inner wall of the main fixer. A cylinder is fixedly installed on the main guide rod, and a positioning block is fixedly installed at the output end of the cylinder. A convex rod is fixed eccentrically on the side of the spray head, and a pull rope is connected between the convex rod and the positioning block.

[0011] Preferably, the secondary clamping mechanism includes a rotating disk rotatably installed on the fixed disk seat. A secondary guide is fixedly installed on the inner wall of the rotating disk. A secondary guide rod is slidably connected in the secondary guide, and a secondary fixer is fixedly connected to the secondary guide rod. An inner moving rod is slidably connected through the secondary guide rod and the secondary fixer. A movable fixer is fixedly installed on the end face of the inner moving rod. An embedded limit spring is elastically connected between the inner moving rod and the secondary guide rod. The bottom of the secondary guide rod is fixedly connected to a guide slide, and the guide slide is slidably connected through the bottom surface of the rotating disk.

[0012] Preferably, an external gear ring is fixedly installed on the outside of the rotating disk, and a driving gear is meshed and connected beside the external gear ring. The driving gear is rotatably connected to the workbench; a plurality of air ducts are provided on the rotating disk.

[0013] Preferably, two groups of support frames are fixedly installed on the workbench. A limiting support rod is slidably connected through the support frame, and an arc-shaped clamping block is fixedly installed on the limiting support rod; an arc-shaped strip is slidably installed on the bottom of the rotating disk along the moving direction of the guiding slide frame. A downward sliding groove is provided on the lower end surface of the arc-shaped strip, and the arc-shaped clamping block is fixedly connected to the downward sliding groove through a bolt.

[0014] Preferably, an upward sliding groove is provided on the upper end surface of the arc-shaped strip, and an embedded clamping block is fitted and slidably connected in the upward sliding groove. The embedded clamping block is fixedly connected to the guiding slide frame.

[0015] Preferably, the two limiting support rods are distributed in a staggered manner on the upper and lower sides of the bidirectional lead screw, and a rack is fitted and installed in the limiting support rod. A planar gear is meshed and connected between the upper and lower two racks; the planar gear is fixedly sleeved on the outside of the bidirectional lead screw.

[0016] Preferably, a disk is fixedly sleeved on the outside of the limiting support rod, and an external spring is elastically connected between the disk and the support frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The adaptive cutting device for alloy special-shaped parts processing can select appropriate points for clamping according to the distribution of the outer contour of the special-shaped workpiece, and clamp and limit the cutting process of the special-shaped workpiece more stably, avoiding problems such as cutting burrs and dimensional deviations, so as to adapt to alloy special-shaped parts of different shapes.

[0018] Furthermore, a main clamping mechanism for directionally limiting the cutting position of the alloy part is arranged on the fixed disk seat along the moving direction of the moving frame. Two relatively stable and symmetrical points on the outside of the special-shaped workpiece are selected, and the special-shaped workpiece is preliminarily clamped and limited by moving the main fixator.

[0019] During the cutting process, the cooling gas can be controlled to be sprayed into the upper and lower spaces of the special-shaped workpiece through the air pipe and the nozzle, quickly cooling the cutting part to keep the alloy part in a better cutting state. At the same time, the nozzle is controlled to rotate left and right reciprocally to expand the jet cooling range, and cooperate with the air duct distribution to improve the cutting and cooling effect of the alloy part.

[0020] Further, a secondary clamping mechanism for defining the cutting position of the turning limiting alloy part is arranged on the fixed disc seat along the moving direction of the sliding seat. According to the external shape of the special-shaped workpiece, the positions of the secondary fixers on both sides of the alloy part are adjusted by rotating the disc. During the process of the main fixer moving and clamping, through power transmission, the secondary fixers also move closer to the alloy part. Moreover, an inner moving rod and a movable fixer are elastically connected to the secondary fixer. Under the thrust of the embedded limiting spring, the movable fixer can elastically press against the side of the alloy part, so that even when the outer contour of the alloy part is asymmetrical, the two groups of movable fixers can still clamp and limit it, maintaining stable cutting and eliminating the need to frequently adjust the position of the clamping tooling on the equipment due to the irregular contour of the alloy special-shaped part.

[0021] While the bidirectional lead screw rotates, it drives the planar gear to rotate. Under the meshing transmission of the planar gear and the rack, it can drive the limiting support rod to move directionally, and the limiting support rod controls the synchronous directional movement of the arc-shaped bar, enabling the support frame to penetrate through the bottom of the rotating disc and move along the radial direction, achieving the purpose of adjusting the position of the secondary fixer.

Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1: Please refer to Figures 1 - 14 , the present invention provides the following technical solutions: An adaptive cutting device for processing alloy special-shaped parts includes a workbench 1 for cutting and processing alloy parts. An electric slide rail 2 is fixedly installed on the workbench 1. A sliding seat 3 is slidably installed on the electric slide rail 2. A gantry 4 is fixedly installed on the upper end surface of the sliding seat 3. A moving frame 5 is horizontally slidably connected to the gantry 4. A lifting frame 6 is vertically slidably connected to the moving frame 5. A laser cutting head 7 is installed on the lifting frame 6; A fixed disk seat 8 is fixedly installed on the workbench 1. A main clamping mechanism for directionally limiting the cutting and processing position of the alloy part is arranged on the fixed disk seat 8 along the moving direction of the moving frame 5, and a secondary clamping mechanism for steering and limiting the cutting and processing position of the alloy part is arranged on the fixed disk seat 8 along the moving direction of the sliding seat 3.

[0039] The main clamping mechanism includes two groups of main guides 9 fixedly installed on the workbench 1. A main guide rod 10 is slidably connected through the main guide 9, and a main fixator 11 is fixedly installed on the main guide rod 10; the main guide rod 10 is connected through the fixed disk seat 8.

[0040] A bidirectional lead screw 12 is rotatably connected to the workbench 1. An internally threaded moving block 13 is sleeved on the bidirectional lead screw 12, and the internally threaded moving block 13 is fixedly connected to the main guide rod 10.

[0041] An air pipe 14 is connected through the main guide rod 10. The port of the air pipe 14 is connected to a spray head 15, and the spray head 15 is rotatably installed on the main fixator 11; an involute spring 16 is elastically connected between the air pipe 14 and the inner wall of the main fixator 11; a cylinder 17 is fixedly installed on the main guide rod 10, a positioning block 18 is fixedly installed at the output end of the cylinder 17, a convex rod 19 is fixedly installed eccentrically on the side of the spray head 15, and a pull rope 20 is connected between the convex rod 19 and the positioning block 18.

[0042] Place the alloy special-shaped part in the rotating disk 21. According to the distribution of the external contour of the alloy special-shaped part, select two appropriate points corresponding to the main fixator 11. Run the motor to control the rotation of the bidirectional lead screw 12. Under the screw drive of the bidirectional lead screw 12 and the internally threaded moving block 13, control the lateral movement of the internally threaded moving block 13. The internally threaded moving block 13 drives the main guide rod 10 and the main fixator 11 to move synchronously. The main fixator 11 moves closer to the alloy special-shaped part and clamps and limits the two points of the alloy special-shaped part, initially fixing the processing position of the alloy special-shaped part.

[0043] During processing, according to the cutting shape of the alloy special-shaped part, the position of the laser cutting head 7 can be adjusted along the X, Y, and Z directions respectively through the moving frame 5, the sliding seat 3, and the lifting frame 6, so as to conveniently cut workpieces with complex shapes.

[0044] During cutting, cool air is input by connecting the air pipe 14. The air pipe 14 is made of flexible hose material. The cold air in the air pipe 14 is sprayed out through the spray head 15. The spray head 15 corresponds to the upper and lower ends of the main fixator 11, and the sprayed gas is distributed above and below the special-shaped workpiece. The upper part of the workpiece is an open structure and dissipates heat quickly. The lower part of the workpiece corresponds to the rotating disk 21, and an air duct 36 is opened at the bottom of the rotating disk 21. The gas sprayed by the spray head 15 can cooperate with the air duct 36 to quickly control the heat dissipation of the workpiece, so as to maintain the temperature of the alloy special-shaped part during cutting and improve the cutting processing quality.

[0045] Embodiment 2: On the basis of Embodiment 1, a secondary clamping mechanism is also disclosed, and its specific structure is as follows: The secondary clamping mechanism includes a rotating disk 21 rotatably mounted on a fixed disk base 8. An inner guide 22 is fixedly installed on the inner wall of the rotating disk 21. A secondary guide rod 23 is slidably connected in the inner guide 22. A secondary fixator 24 is fixedly connected to the secondary guide rod 23. An inner moving rod 25 is slidably connected through the secondary guide rod 23 and the secondary fixator 24. A movable fixator 26 is fixedly installed on the end face of the inner moving rod 25. An embedded limit spring 27 is elastically connected between the inner moving rod 25 and the secondary guide rod 23. The bottom of the secondary guide rod 23 is fixedly connected to a guide slide 28, and the guide slide 28 is slidably connected through the bottom surface of the rotating disk 21.

[0046] An external gear ring 211 is fixedly installed outside the rotating disk 21. A driving gear 212 is meshed and connected beside the external gear ring 211. The driving gear 212 is rotatably connected to the workbench 1. A plurality of air ducts 36 are provided on the rotating disk 21.

[0047] Two support frames 29 are fixedly installed on the workbench 1. A limit support rod 30 is slidably connected through the support frame 29. An arc-shaped clamping block 31 is fixedly installed on the limit support rod 30. An arc-shaped strip 32 is slidably installed at the bottom of the rotating disk 21 along the moving direction of the guide slide 28. A downward chute 33 is provided on the lower end face of the arc-shaped strip 32. The arc-shaped clamping block 31 is fixedly connected to the downward chute 33 by bolts.

[0048] An upward chute 34 is provided on the upper end face of the arc-shaped strip 32. An embedded clamping block 35 is slidably fitted and connected in the upward chute 34. The embedded clamping block 35 is fixedly connected to the guide slide 28.

[0049] The two limit support rods 30 are staggeredly distributed on the upper and lower sides of the bidirectional lead screw 12. A rack 37 is fitted and installed in the limit support rod 30. A planar gear 38 is meshed and connected between the upper and lower racks 37. The planar gear 38 is fixedly sleeved on the outside of the bidirectional lead screw 12.

[0050] An external spring 40 is elastically connected between an external disk 39 fixedly sleeved on the outside of the limit support rod 30 and the support frame 29.

[0051] Only clamping and limiting by the main fixator 11 is not conducive to stable cutting and processing for some alloy parts with large volume, heavy weight and irregular contours. Before clamping and cutting, according to the distribution of the outer contour of the alloy special-shaped part, adjust the corresponding position of the secondary fixator 24. Operate the motor on the workbench 1 to control the rotation of the driving gear 212. The driving gear 212 is meshed and connected with the external gear ring 211. Under the meshing drive, the external gear ring 211 and the rotating disk 21 can be driven to rotate. The rotating disk 21 drives the secondary fixator 24 to rotate, and adjusts the corresponding clamping position of the secondary fixator 24.

[0052] During the rotation of the rotating disk 21, the support frame 29 rotates synchronously, and the embedded clamping block 35 below the support frame 29 slides and moves in the arc-shaped strip 32. While the bidirectional lead screw 12 rotates to adjust the clamping position of the main fixator 11, the bidirectional lead screw 12 synchronously drives the planar gear 38 to rotate. The planar gear 38 is meshed and connected with the rack 37. Under the meshing drive, the relative movement of the two groups of racks 37 can be controlled. The rack 37 is fixedly installed on the limiting support rod 30, and it controls the limiting support rod 30 to slide through the support frame 29. The limiting support rod 30 controls the synchronous movement of the arc-shaped clamping block 31 and the arc-shaped strip 32. During the directional movement of the arc-shaped strip 32, it can push the support frame 29 to move radially along the bottom of the rotating disk 21. At the same time, the embedded clamping block 35 at the bottom of the support frame 29 slides correspondingly in the upper sliding groove 34. The movement of the support frame 29 can drive the secondary guide rod 23 and the secondary fixator 24 to move closer to the alloy special-shaped part, achieving the purpose of further clamping and limiting the alloy special-shaped part.

[0053] The port of the secondary fixator 24 is elastically connected with an inner moving rod 25 and a movable fixator 26 through an embedded limiting spring 27. The movable fixator 26 first moves closer to the alloy special-shaped part, and after the movable fixator 26 moves and contacts the alloy special-shaped part, it squeezes the embedded limiting spring 27. Under the elastic pressure, a certain clamping range can be maintained. Even when the outer contour of the alloy special-shaped part is irregular, the two-sided movable fixators 26 can still elastically clamp the outside of the workpiece, keeping the alloy special-shaped part stably clamped and cut, and avoiding problems such as cutting burrs and dimensional deviations.

[0054] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
