Description

Technical Field

[0001] The invention relates to the technical field of aerosol jet printing nozzles, and in particular to a fixing device for an aerosol jet printing nozzle. Background Art

[0002] Aerosol jet printing is a new type of 3D printing technology that uses aerosol as material and builds objects layer by layer by controlling the flow state and solidification process of aerosol in the air. This technology can be applied to a variety of fields, including biomedicine, electronic devices, micro-nano structures, etc., and has attracted much attention due to its advantages of high resolution, rapid prototyping, and material saving.

[0003] A Chinese patent with publication number CN221315149U discloses a fixing device for an aerosol jet printing nozzle, including a fixing ring, a groove is arranged on the inner wall of the fixing ring, a spring is arranged in the groove, the spring extends out of the groove in a free state, a top plate is arranged on the spring, threaded holes are arranged on both sides of the fixing ring, and bolts are arranged in the threaded holes. The spring and top plate provided by the present invention, when the nozzle is inserted into the fixing ring from top to bottom, the outer wall of the nozzle will hit the top plate, and squeeze the top plate and the spring to make the two retract into the groove, and the top plate and the nozzle are closely contacted by the rebound force of the spring, so that the nozzle is fixed more firmly, and at the same time, the spring has a buffering effect, when the nozzle is subjected to external impact or vibration, the spring can absorb and reduce the impact of these forces, reduce the adverse effects caused by external interference, and provide a more reliable working environment.

[0004] In the prior art, after the nozzle is connected to the fixing bracket, the fixing bracket needs to be connected to the printing device for use. Currently, the installation work is completed by connecting the fixing bracket to the printing device through multiple screws. Since there are many threaded holes that need to be connected, the installation is slow. In addition, when the height of the nozzle needs to be adjusted, the fixing bracket is not easy to adjust due to the threaded holes. Summary of the invention

[0005] The present invention provides a fixing device for an aerosol jet printing nozzle to solve the problems raised by the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution of the present invention is as follows: An embodiment of the present invention provides a fixing device for an aerosol jet printing nozzle, comprising: a fixing frame, the surface of the fixing frame is threadedly connected to two limit screws, the surface of the fixing frame is fixedly connected to four telescopic rods, one end of the four telescopic rods is fixedly connected to a pressure plate, the surfaces of the four telescopic rods are sleeved with springs, the two ends of the springs are respectively fixedly connected to the fixing frame and the pressure plate, the surface of the fixing frame is slidably connected to a mounting plate, the surface of the mounting plate is provided with two threaded holes, the surface of the mounting plate is rotatably connected to a bidirectional screw, the surface of the fixing frame is slidably connected to two sliding blocks, the bidirectional screw is rotatably connected to the sliding block, the surface of the bidirectional screw is threadedly connected to two limit plates, and the surface of the bidirectional screw is fixedly connected to a connecting plate.

[0007] Through the above technical solution, the fixing frame is connected to the printing device through the threaded hole, and the fixing frame can be driven to adjust its position by sliding the mounting plate, thereby increasing the practicality of the fixing frame.

[0008] Furthermore, the surfaces of the two limit screws are rotatably connected with connection blocks, and both sides of the fixing frame are slidably connected with sliding plates, and the sliding plates are fixedly connected to the connection blocks.

[0009] Through the above technical solution, when the limiting screw is rotated in the reverse direction, the sliding plate will limit the limiting screw so that it will not be separated from the fixing frame.

[0010] Furthermore, both ends of the two threaded holes are chamfered surfaces.

[0011] Through the above technical solution, the opening of the chamfered surface can facilitate the staff to use external screws to connect the fixing frame to the printing device.

[0012] Furthermore, two support plates are fixedly connected to the surface of the fixing frame, and both of the two support plates are slidably connected to the mounting plate.

[0013] Through the above technical solution, when the fixing frame is hit, the support plate can support the mounting plate, so that the position where the mounting plate is connected to the printing device is not easily damaged.

[0014] Furthermore, the two limiting plates are both in a "U" shape.

[0015] Through the above technical solution, through the special shape design of the limit plate, when the bidirectional screw drives the limit plate to move, it will not cause the limit plate to rotate.

[0016] Furthermore, the inner walls of the two limiting plates are both glued with anti-skid pads, and the anti-skid pads are made of rubber.

[0017] Through the above technical solution, the anti-skid pad can increase the friction after the limiting plate abuts against the surface of the fixing frame, so that the limiting plate can limit the position of the mounting plate more stably.

[0018] Furthermore, the surfaces of the two limit plates are fixedly connected with connecting disks, the surfaces of the connecting plates are fixedly connected with connecting rods, and the connecting rods are slidably connected with the connecting disks.

[0019] Through the above technical solution, the bidirectional screw is driven to rotate by rotating the connecting rod, which reduces the pain felt by the staff's hands when rotating the connection and facilitates the rapid rotation of the bidirectional screw.

[0020] The above solution of the present invention includes at least the following beneficial effects: The present invention can be fixed in multiple places on the fixing frame by arranging the mounting plate, the limiting plate and the bidirectional screw. When the height of the nozzle needs to be adjusted, it can be conveniently adjusted by sliding the mounting plate, thereby increasing the practicality of the fixing frame. In addition, the reduction of the threaded holes on the surface can increase the installation and disassembly efficiency between the fixing frame and the printing device.

The surfaces of the two limit screws 2 are rotatably connected with the connecting blocks 6, and the two sides of the fixing frame 1 are slidably connected with the sliding plates 7, and the sliding plates 7 are fixedly connected with the connecting blocks 6. When the limit screws 2 are rotated in the opposite direction, the sliding plates 7 will limit the limit screws 2 so that they will not be separated from the connection with the fixing frame 1. The two threaded holes 9 Both ends are chamfered surfaces 10. The chamfered surfaces 10 can facilitate the staff to use external screws to connect the fixing frame 1 to the printing device.
