Description

Technical Field

[0001] This utility model relates to the field of additive manufacturing technology, and in particular to an additive manufacturing equipment for aerospace components. Background Technology

[0002] Additive manufacturing equipment utilizes additive manufacturing technology to directly manufacture parts with complex shapes and internal structures by layering materials, eliminating the need for traditional molds and cutting processes, thus greatly improving design freedom and manufacturing efficiency.

[0003] In the manufacturing of aerospace parts, existing technology requires placing materials into a molten pool, with a cylinder fixing the molten pool via a clamp, and then a laser melting the material in the molten pool. However, the force of the cylinder is not easy to control, and the molten pool is easily damaged by the clamp driven by the cylinder. Utility Model Content

[0004] This utility model proposes an additive manufacturing equipment for aerospace components to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an additive manufacturing equipment for aerospace parts, including a housing, which is placed on the ground to provide support for the whole, a laser device is fixedly connected inside the housing, a molten pool is placed inside the housing, wherein the molten pool is located inside the laser device, two cylinders are respectively installed inside the housing, and a clamping plate is fixedly connected to the output end of the cylinders, and a limiting device is located on one side of the clamping plate, wherein the limiting device can limit the maximum displacement of the clamping plate.

[0006] The effect achieved by the above components is as follows: when it is necessary to process aerospace parts, the worker places the material into the molten pool and places the molten pool between two clamping plates. The cylinder is opened, and the cylinder moves the clamping plates. Finally, the clamping plates limit the molten pool. The limiting device limits the maximum displacement of the clamping plates to prevent the clamping plates from damaging the molten pool. Finally, the laser equipment melts the material in the molten pool to complete the processing of the aerospace parts.

[0007] Preferably, the limiting device includes a fixing tube, which is fixedly connected to one end of one of the clamping plates, and a threaded cylinder is fixedly connected to one end of the other clamping plate. A screw is threadedly connected inside the threaded cylinder, and a fixing rod is fixedly connected to one end of the screw, wherein the size of the fixing rod is adapted to the internal size of the fixing tube.

[0008] The aforementioned components achieve the following effect: When it is necessary to fix the molten pool, the operator first rotates the fixing rod, which rotates the screw inside the threaded cylinder, changing the total length of the screw and the threaded cylinder. After adjusting to the appropriate length, the operator stops rotating the screw. When the cylinder brings the two clamping plates closer to each other, the fixing rod on the screw inserts into the interior of the fixing tube. The space inside the fixing tube becomes smaller, and the air pressure inside the fixing tube increases, thereby slowing down the movement speed of the fixing rod and achieving the effect of slowing down the movement of the clamping plates. When the two clamping plates move to both sides of the molten pool, one end of the fixing rod abuts against the interior of the fixing tube, limiting the clamping plates. The limiting device achieves the effect of limiting the maximum displacement of the clamping plates, preventing the clamping plates from damaging the molten pool and thus affecting the processing of aerospace parts.

[0009] Preferably, the arc surface of the fixing rod is fixedly connected to three control blocks, which are distributed in a circular pattern.

[0010] The effect achieved by the above components is to increase the contact area between the worker's hand and the fixed rod by setting the control block, making it easier for the worker to rotate the fixed rod.

[0011] Preferably, a rubber pad is fixedly connected to the end of the fixing rod away from the screw, wherein the size of the rubber pad is adapted to the size of the fixing rod.

[0012] The effect achieved by the above-mentioned components is that the rubber pads protect the fixing rod and prevent damage caused by contact and collision between the fixing rod and the inner wall of the fixing tube.

[0013] Preferably, one end of the fixed tube is provided with a slope, wherein the slope is inclined toward the inside of the fixed tube.

[0014] The effect achieved by the above components is that by setting up a ramp, the fixing rod is guided, making it easier for the fixing rod to enter the interior of the fixing tube.

[0015] Preferably, the arc surface of the fixed tube is provided with a pressure relief device, the pressure relief device includes a pressure relief pipe, the pressure relief pipe is fixedly connected to the arc surface of the fixed tube, wherein the pressure relief pipe is in communication with the interior of the fixed tube, a spring is fixedly connected inside the pressure relief pipe, one end of the spring is located outside the pressure relief pipe and is fixedly connected to a cover plate, wherein the size of the cover plate is larger than the internal size of the pressure relief pipe.

[0016] The effect achieved by the above components is as follows: when the air pressure inside the fixed tube is too high, the gas inside the fixed tube squeezes the cover plate at one end of the pressure relief tube. The cover plate moves away from the pressure relief tube, the spring on the pad deforms, and the gas flows out of the cover plate through the pressure relief tube. When the fixed rod is against the bottom of the fixed tube, the cover plate covers the pressure relief tube under the action of the spring's return force, making it convenient for the next use. The pressure relief device achieves the effect of relieving the gas inside the fixed tube, avoiding excessive air pressure inside the fixed tube, which could lead to damage to the fixed tube.

[0017] Preferably, a rubber ring is fixedly connected to one end of the pressure relief pipe, wherein the size of the rubber ring is adapted to the size of the pressure relief pipe.

[0018] The effect achieved by the above components is that the rubber ring protects the cover plate and prevents it from being damaged by collision with the pressure relief pipe.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] When it is necessary to fix the molten pool, the operator first rotates the fixing rod. The fixing rod, along with the screw, rotates inside the threaded cylinder, changing the total length of the screw and the threaded cylinder. After adjusting to the appropriate length, the operator stops rotating the screw. When the cylinder brings the two clamping plates closer together, the fixing rod on the screw inserts into the fixing tube. The space inside the fixing tube decreases, and the air pressure inside the fixing tube increases, thereby slowing down the movement speed of the fixing rod. This achieves the effect of slowing down the movement of the clamping plates. When the two clamping plates move to both sides of the molten pool, one end of the fixing rod abuts against the inside of the fixing tube, limiting the clamping plates. The limiting device restricts the maximum displacement of the clamping plates, preventing the clamping plates from damaging the molten pool and affecting the processing of aerospace parts.

[0026] Reference Figure 1-4 As shown, this embodiment discloses an additive manufacturing equipment for aerospace parts, including a housing 1, which is placed on the ground to provide support for the entire assembly. A laser device 2 is fixedly connected inside the housing 1, and a molten pool is placed inside the housing 1, with the molten pool located inside the laser device 2. Two cylinders 3 are respectively installed inside the housing 1, and clamping plates 4 are fixedly connected to the output ends of the cylinders 3. A limiting device 5 is located on one side of the clamping plate 4, which can limit the maximum displacement of the clamping plate 4. When aerospace parts need to be processed, the operator places the material into the molten pool and positions the molten pool between the two clamping plates 4. The cylinders 3 are then activated, causing the cylinders 3 to move the clamping plates 4. Ultimately, the clamping plates 4 limit the molten pool, and the limiting device 5 restricts the maximum displacement of the clamping plates 4 to prevent damage to the molten pool. Finally, the laser device 2 melts the material in the molten pool, completing the processing of the aerospace parts.

[0027] Reference Figure 1-4 As shown, the limiting device 5 includes a fixing tube 54, which is fixedly connected to one end of one of the clamping plates 4. A threaded cylinder 51 is fixedly connected to one end of the other clamping plate 4. A screw 52 is threadedly connected inside the threaded cylinder 51. A fixing rod 53 is fixedly connected to one end of the screw 52. The size of the fixing rod 53 is adapted to the internal size of the fixing tube 54. When it is necessary to fix the molten pool, the operator first rotates the fixing rod 53. The fixing rod 53 rotates the screw 52 inside the threaded cylinder 51, changing the total length of the screw 52 and the threaded cylinder 51. After adjusting to the appropriate length, the operator stops rotating the screw 52. When the cylinder 3 brings the two clamping plates 4 closer to each other, the fixing rod 53 on the screw 52 inserts into the fixing tube 54. The space inside the fixing tube 54 becomes smaller, and the air pressure inside the fixing tube 54 increases, thereby slowing down the movement speed of the fixing rod 53. This achieves the effect of slowing down the movement of the clamping plates 4. When the two clamping plates 4 move to both sides of the molten pool, one end of the fixing rod 53 abuts against the inside of the fixing tube 54, limiting the clamping plates 4. The limiting device 5 achieves the effect of limiting the maximum displacement of the clamping plates 4, preventing the clamping plates 4 from damaging the molten pool and affecting the processing of aerospace parts.

[0028] Reference Figure 1-4As shown, three control blocks 56 are fixedly connected to the arc surface of the fixing rod 53, and the three control blocks 56 are circumferentially distributed. The control blocks 56 increase the contact area between the worker's hand and the fixing rod 53, facilitating rotation of the fixing rod 53. A rubber pad 57 is fixedly connected to the end of the fixing rod 53 away from the screw 52, ​​and the size of the rubber pad 57 is adapted to the size of the fixing rod 53. The rubber pad 57 provides protection for the fixing rod 53, preventing damage from contact and collision with the inner wall of the fixing tube 54. A ramp 55 is provided at one end of the fixing tube 54, which slopes inwards. The ramp 55 guides the fixing rod 53, facilitating its entry into the fixing tube 54.

[0029] Reference Figure 1-4 As shown, the arc surface of the fixed pipe 54 is provided with a pressure relief device 6. The pressure relief device 6 includes a pressure relief pipe 61, which is fixedly connected to the arc surface of the fixed pipe 54. The pressure relief pipe 61 is in communication with the interior of the fixed pipe 54. A spring 63 is fixedly connected inside the pressure relief pipe 61. One end of the spring 63 is located outside the pressure relief pipe 61 and is fixedly connected to a cover plate 64. The size of the cover plate 64 is larger than the internal size of the pressure relief pipe 61. When the air pressure inside the fixed tube 54 is too high, the gas inside the fixed tube 54 squeezes the cover plate 64 at one end of the pressure relief tube 61. The cover plate 64 moves away from the pressure relief tube 61, and the spring 63 on the pad 62 deforms. The gas flows out of the cover plate 64 through the pressure relief tube 61. When the fixed rod 53 abuts against the bottom of the fixed tube 54, the cover plate 64 covers the pressure relief tube 61 under the action of the spring 63's return force, making it convenient for the next use. The pressure relief device 6 achieves the effect of relieving the gas inside the fixed tube 54, avoiding excessive air pressure inside the fixed tube 54, which could lead to damage to the fixed tube 54.

[0030] Reference Figure 1-4 As shown, a rubber ring 65 is fixedly connected to one end of the pressure relief pipe 61, and the size of the rubber ring 65 is adapted to the size of the pressure relief pipe 61. By setting the rubber ring 65, the cover plate 64 is protected, preventing damage from collision between the cover plate 64 and the pressure relief pipe 61.

[0031] Working principle: Before processing the aerospace parts, the operator first rotates the fixing rod 53 via the control block 56. The fixing rod 53, along with the screw 52, ​​rotates inside the threaded cylinder 51, changing the total length of the screw 52 and the threaded cylinder 51. Once the appropriate length is reached, the operator stops rotating the control block 56. Then, the operator places the material into the molten pool and positions the molten pool between the two clamping plates 4. The cylinder 3 is then activated, causing the two clamping plates 4 to move closer together. The fixing rod 53 on the screw 52 is inserted into the fixing tube 54 via the ramp 55. As the internal space decreases, the air pressure inside the fixing tube 54 increases, thereby slowing down the movement speed of the fixing rod 53 and achieving the effect of slowing down the movement of the clamping plate 4. When the two clamping plates 4 move to both sides of the molten pool, the fixing rod 53, with the help of the rubber pad 57, presses against the inside of the fixing tube 54 to limit the clamping plate 4. The two clamping plates 4 fix the molten pool. Finally, the laser equipment 2 melts the material in the molten pool to complete the processing of the aerospace parts. The limiting device 5 achieves the effect of limiting the maximum displacement of the clamping plate 4, preventing the clamping plate 4 from damaging the molten pool and thus affecting the processing of the aerospace parts.

[0032] When the air pressure inside the fixed tube 54 is too high, the gas inside the fixed tube 54 squeezes the cover plate 64 at one end of the pressure relief tube 61. The cover plate 64 moves away from the pressure relief tube 61, and the spring 63 on the pad 62 deforms. The gas flows out of the cover plate 64 through the pressure relief tube 61. When the fixed rod 53 abuts against the bottom of the fixed tube 54, under the action of the spring 63's return force, the cover plate 64 moves back to its original position and fits against the rubber ring 65 on the pressure relief tube 61 for easy use next time. The pressure relief device 6 achieves the effect of relieving the gas inside the fixed tube 54, avoiding excessive air pressure inside the fixed tube 54, which could lead to damage to the fixed tube 54.
