Description

Technical Field

[0001] This utility model relates to the field of metal powder processing technology, and in particular to a powder cleaning device for additive manufacturing of an injector. Background Technology

[0002] Additive manufacturing of fuel injectors refers to the process of directly forming fuel injector components with complex internal flow channels and microstructures by depositing metal or alloy materials layer by layer using additive manufacturing technology. This process breaks through the limitations of geometric freedom imposed by traditional casting and machining, enabling the integrated manufacturing of the injector and reducing the number of welds and connectors. Through topology optimization and lattice structure design, additive manufacturing can effectively reduce the weight of the injector and improve combustion efficiency and thermal management performance. After the injector is manufactured using additive manufacturing technology, a powder cleaning device is needed to clean the metal powder from its surface and interior.

[0003] Currently, the powder cleaning device used in additive manufacturing injectors mainly consists of a fixed air blowing nozzle, an external vibration table, and a powder collection box. The air blowing nozzle is connected to the air source through a pipeline and is set towards the injector inlet. The vibration table supports the entire injector and transmits vibration. The collection box is located below the injector to collect the falling powder.

[0004] Because the injector has multiple levels of intersecting channels and fine cooling channels inside, the fixed air nozzle can only blow straight through the inlet area and cannot reach deep into the channel, resulting in a large amount of powder being trapped in the dead corner area. At the same time, the external vibration table simply shakes the injector from side to side, which cannot generate effective vibration. Some powder adhering to the bends of the channel cannot be dislodged by vibration, resulting in poor powder removal effect. The residual powder will block the channel or affect the injection accuracy during subsequent use. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems existing in the existing powder cleaning device for additive manufacturing of injectors, this utility model is proposed.

[0007] Therefore, the problem that this invention aims to solve is that the current powder cleaning device for additive manufacturing of injectors cannot penetrate deep into the flow channel, resulting in a large amount of powder remaining in the cleaning dead zone of the flow channel, which affects the dust removal effect of the injector.

[0008] To solve the above technical problems, this utility model provides the following technical solution: a powder cleaning device for additive manufacturing of an injector, comprising a base and an active powder cleaning assembly. A fixing frame is fixedly connected to the rear side of the base, and an adjustment mechanism is provided on the rear side of the fixing frame.

[0015] As a preferred embodiment of the powder cleaning device for additive manufacturing of the injector described in this utility model, a positioning rod is fixedly connected to the front and rear sides between the two sides of the inner cavity of the base.

[0018] The beneficial effects of this utility model are as follows: By adjusting the mechanism to control the left and right movement of the movable frame, the jet pipe is aligned with different positions of the injector. The drive motor, screw, and threaded sleeve work together to achieve positioning. The jet pipe is moved downwards and overcomes the resistance of the adjusting spring, allowing the mesh tube to enter the depth of the flow channel. The air pump provides airflow through the hose. The airflow drives the paddle to drive the turntable and rotating tube to rotate the mesh tube. The rotating airflow sprayed from the mesh on its surface can clean the powder inside the flow channel and at the corners. At the same time, it enhances the work of the vibration mechanism. The servo motor drives the cam to periodically push the push plate, which, together with the return spring, makes the housing sway left and right. The mesh plate catches the falling powder. The impact block rotates with the servo motor and strikes the steel vibration plate, generating vibration that is transmitted to the injector, causing the attached powder to fall off. The fallen powder is carried by the airflow through the soft tubing into the filter shell, where it is filtered and collected by the filter element. The exhaust fan maintains the airflow circulation, solving the problem of powder residue deep in the flow channel caused by fixed purging and simple vibration in the background technology, and improving the powder cleaning effect of the injector.

[0043] Specifically, the slider and the sliding sleeve can limit the position of the blocking frame 16, enabling it to be stably adjusted up and down.

[0044] Example 3, referring to Figure 7 and Figure 8 This is the third embodiment of the present invention. Based on the previous two embodiments, the bottom of the inner cavity of the base 1 is provided with a vibration enhancement mechanism 9. The vibration enhancement mechanism 9 includes a servo motor 91. The bottom of the output end of the servo motor 91 is fixedly connected to the inner wall of the base 1. A cam 92 is fixedly connected to the front side of the output end of the servo motor 91. A push plate 93 is provided on the right side of the cam 92. A return spring 94 is fixedly connected to the right side of the push plate 93. A housing 95 is fixedly connected to the top of the push plate 93. A mesh plate 96 is fixedly connected between the two sides of the inner cavity of the housing 95.

[0045] Specifically, the servo motor 91 can control the rotation of the cam 92, and the cam 92 can cooperate with the return spring 94 to control the push plate 93 housing 95 to continuously sway left and right, and the mesh plate 96 can facilitate the powder to enter the filter housing 12.

[0046] An impact block 10 is fixedly connected to the rear side of the output end of the servo motor 91, and steel vibration plates 11 are fixedly connected to both sides of the rear side of the bottom of the base 1.

[0047] Specifically, the impact block 10 can work with the servo motor 91 to continuously impact the steel vibrating plate 11, causing the steel vibrating plate 11 to vibrate continuously, thereby improving the dust removal effect on the injector.

[0048] A filter housing 12 is fixedly connected to the left side of the bottom of the inner cavity of the base 1. A filter element 13 is fixedly connected to the bottom of the inner cavity of the filter housing 12. The right side of the filter housing 12 is connected to the housing 95 through a soft tubing. An exhaust fan 14 is connected to the left side of the filter housing 12. The left end of the exhaust fan 14 extends to the outside of the base 1.

[0049] Specifically, the filter housing 12 can work with the filter element 13 to filter powder, and the soft tubing can transport the powder inside the housing 95 to the inside of the filter housing 12.

[0050] Positioning rods are fixedly connected to the front and rear sides of the inner cavity of the base 1. Positioning sleeves are slidably connected to the surface of the positioning rods, and the surface of the positioning sleeves is fixedly connected to the push plate 93.

[0051] Specifically, the positioning rod and positioning sleeve can limit the push plate 93, improving the stability during its left and right position adjustment process.

[0052] During use, the sprayer to be cleaned is first placed on the mesh plate 96 inside the housing 95. The electric actuator 15 is activated to raise the shielding frame 16 to form a barrier. Then, the operator can hold the handle on the side of the pressure plate 44 and press down on the jet pipe 43 to overcome the resistance of the adjusting spring 45, controlling the mesh tube 5 at the bottom of the jet pipe 43 to be inserted deep into the internal flow channel of the sprayer. The air pump 46 is activated, and the airflow is delivered to the inside of the jet pipe 43 through the hose 47. The high-speed airflow acts on the blade 8, driving the turntable 7 and the rotating tube 6 to rotate together, thereby driving the mesh tube 5 connected to it to rotate in the flow channel. The rotating mesh tube 5 sprays multi-directional rotating airflow from its mesh holes, effectively flushing the powder attached to the inner wall and corners of the flow channel. In order to cover the different flow channel inlets of the sprayer, the drive motor 32 can be activated. The drive motor 32 drives the screw 33 to rotate, driving the threaded sleeve 34 that is threaded to it to move horizontally along the direction defined by the guide rail and the slider, thereby carrying The entire movable frame 41 and jet pipe 43 are precisely adjusted to the left and right positions. While actively blowing, the servo motor 91 is started, and the cam 92 on the front side of the output shaft of the servo motor 91 rotates accordingly, periodically pushing the push plate 93 on the right side. The push plate 93 overcomes the elastic force of the return spring 94 and moves to the left. When the cam 92 rotates away, the push plate 93 returns to its original position under the action of the return spring 94. This cycle causes the push plate 93 and the housing 95 fixed on it to drive the mesh plate 96 and the sprayer to continuously shake left and right to loosen the powder. At the same time, the impact block 10 on the rear side of the output shaft of the servo motor 91 rotates with the shaft and continuously strikes the steel vibration plates 11 on both sides, generating high-frequency vibration and transmitting it to the housing 95, further enhancing the shaking effect. The powder washed away by the airflow and shaken off is sucked into the filter housing 12 through the mesh plate 96 and the soft tube under the suction generated by the exhaust fan 14. After being filtered by the filter element 13, it is collected, and the clean air is discharged by the exhaust fan 14.
