Description

Technical Field

[0001] This utility model relates to the field of aircraft model manufacturing technology, and in particular to a screen printing positioning fixture for aircraft model shells. Background Technology

[0002] Model aircraft refers to a collective term for small, heavier-than-air, unmanned aircraft manufactured according to aerodynamic principles that can fly within the Earth's atmosphere. During the manufacturing process, the model aircraft shell needs to have information such as logos, numbers, decorative patterns, or functional descriptions added through screen printing.

[0003] To ensure the accuracy of the silkscreen pattern position and avoid offsets, skewing, or rework caused by manual positioning errors, a fixture is used to position the model aircraft shell. Model aircraft shells have various structures, while the fixture has a relatively simple structure and can only position model aircraft shells with the same structure. When different model aircraft shells need to be silkscreened, the fixture must be changed. The operation is cumbersome and affects work efficiency. Utility Model Content

[0004] In view of this, the present invention provides a screen printing positioning fixture for model aircraft shells, which can overcome the disadvantage that the fixture needs to be changed every time a different model aircraft shell is screen printed, which is cumbersome and affects work efficiency.

Hydraulic oil is filled in both the housing and the piston cylinders. The sealing assembly is used to seal the through holes to prevent the hydraulic oil in the piston cylinders from flowing. The fixing assembly is used to fix the model aircraft shell.

[0007] Furthermore, the sealing assembly includes a piston plate, plugs, and an electric push rod. The piston plate is slidably connected inside the housing, and the hydraulic oil inside the housing is located above the piston plate. Plugs for sealing the through holes are evenly spaced on the top of the piston plate. An electric push rod is installed at the bottom of the housing, and the telescopic rod of the electric push rod is connected to the bottom of the piston plate.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0029] refer to Figures 1-7 A screen printing positioning fixture for model aircraft shell includes a base 1, a support plate 2, a slide plate 3, a screen printing machine 4, a cylinder 5, and a support mechanism. The support plate 2 is bolted to the top rear side of the base 1, and the slide plate 3 is slidably connected to the support plate 2. The screen printing machine 4 is bolted to the front side of the slide plate 3, and the cylinder 5 is bolted to the rear side of the support plate 2. The telescopic rod of the cylinder 5 is bolted to the rear side of the slide plate 3. The support mechanism is used to support the model aircraft shell.

[0030] refer to Figures 3-7The support mechanism includes a housing 6, a mounting plate 7, piston cylinders 8, piston blocks 9, support rods 10, a sealing assembly, and a fixing assembly. The housing 6 is bolted to the top front of the base 1. The mounting plate 7 is connected to the lower part of the housing 6. Piston cylinders 8 are evenly spaced on the mounting plate 7. Piston blocks 9 are slidably sealed inside each piston cylinder 8. Support rods 10 are connected to the top of each piston block 9. The upper end of the support rod 10 is a ball to avoid wear on the model's shell. Each piston cylinder 8 has a through hole 11 at the bottom. Hydraulic oil is filled in both the housing 6 and the piston cylinders 8. The sealing assembly is used to seal the through holes 11 to prevent the hydraulic oil in the piston cylinders 8 from flowing. The fixing assembly is used to fix the model's shell.

[0031] refer to Figure 4 and Figure 6 The sealing assembly includes a piston plate 12, a plug 13, and an electric push rod 14. The piston plate 12 is slidably connected to the lower part of the housing 6. The piston plate 12 is located below the mounting plate 7. The hydraulic oil in the housing 6 is located above the piston plate 12. The top of the piston plate 12 is evenly spaced with plugs 13. The plugs 13 are made of rubber and the top of the plugs 13 is hemispherical, which can better contact the inside of the through hole 11, thereby better blocking the through hole 11. The electric push rod 14 is bolted to the middle of the bottom of the housing 6. The telescopic rod of the electric push rod 14 is connected to the bottom of the piston plate 12.

[0032] refer to Figure 5 and Figure 7 The fixing component includes a circular block 15 and an annular airbag 16. The upper part of the piston cylinder 8 is connected to the circular block 15, which is located above the piston block 9. The support rod 10 slides through the circular block 15. The upper part of the support rod 10 is connected to the annular airbag 16. The support rod 10 has venting grooves 17 evenly spaced around its circumference. The piston cylinder 8 and the annular airbag 16 are connected through the venting grooves 17.

[0033] Initially, the plug 13 does not seal the through hole 11, the hydraulic oil in the housing 6 and piston cylinder 8 is horizontal, and the support rods 10 are flush with each other. When the operator places the model aircraft shell on the support rods 10 and presses it down, the support rod 10 in contact with the model aircraft shell moves downwards, and the piston block 9 connected to that support rod 10 also moves downwards. The hydraulic oil in the piston cylinder 8 flows into the housing 6 through the through hole 11. The air in the annular airbag 16 corresponding to the support rod 10 in contact with the model aircraft shell flows into the piston cylinder 8 through the venting groove 17, causing the annular airbag 16 to contract. Simultaneously, the hydraulic oil in the housing 6 flows into the piston cylinder 8 corresponding to the support rod 10 not in contact with the model aircraft shell through the through hole 11. The piston block 9 and support rod 10 in the piston cylinder 8 move upwards, and the air in the piston cylinder 8 corresponding to the support rod 10 not in contact with the model aircraft shell flows into the annular airbag 16 through the venting groove 17, causing the annular airbag 16 to expand. The expanded annular airbag 16 can solidify the model aircraft shell. The support rod 10 can support the model aircraft shell, and the support rod 10 and the annular airbag 16 can be adapted to model aircraft shells with different structures, eliminating the need for frequent clamp changes and thus improving work efficiency. Then, the operator controls the extension rod of the electric push rod 14 to extend, driving the piston plate 12 to move upward. The piston plate 12 drives the block 13 to move upward, blocking the through hole 11 and preventing the hydraulic oil in the piston cylinder 8 from flowing. This prevents the piston block 9 and the support rod 10 from moving. The operator can then control the extension rod of the cylinder 5 to shorten, driving the slide plate 3 to move downward. The slide plate 3 drives the screen printing machine 4 to move downward, bringing the screen printing machine 4 close to the model aircraft shell for screen printing. After screen printing is completed, the screen-printed model aircraft shell can be removed. The support rod 10 and the annular airbag 16 can maintain a state of structural adaptation with the model aircraft shell. The operator places the next model aircraft shell on the support rod 10, and the support rod 10 and the annular airbag 16 can automatically position the model aircraft shell.

[0034] refer to Figure 8 It also includes a flattening mechanism, which includes a connecting block 18, a guide rod 19, a sliding plate 20 and a pressure plate 21. The top left and right sides of the base 1 are connected to the connecting block 18 by bolts. The upper part of the connecting block 18 is connected to the guide rod 19. The two guide rods 19 are respectively connected to the left and right sides of the box 6. The sliding plate 20 is slidably connected to the guide rod 19. The top of the two sliding plates 20 is connected to the pressure plate 21.

[0035] The staff places the model aircraft shell on the support rod 10 and presses it down. Then, they push the pressure plate 21 forward to push it above the model aircraft shell. The bottom of the pressure plate 21 will contact the top of the model aircraft shell, and the pressure plate 21 will press down on the model aircraft shell, so that the model aircraft shell can remain in a horizontal state and ensure the clarity of the silk screen pattern.

[0036] refer to Figure 9and Figure 10 It also includes an adsorption mechanism, which includes a slider 23, an iron block 24, an electromagnet 25, a spring 26, and a sealing ring 28. The upper end of the support rod 10 is provided with an installation groove 22, and a slider 23 is slidably and sealingly connected in the installation groove 22. An iron block 24 is connected to the bottom of the slider 23. An electromagnet 25 is installed at the bottom of the installation groove 22. A spring 26 is connected between the top of the electromagnet 25 and the bottom of the slider 23. Vent holes 27 are provided on the left and right sides of the upper part of the support rod 10. The vent holes 27 are connected to the installation groove 22. The upper end of the support rod 10 is connected with a sealing ring 28.

[0037] After the pressure plate 21 presses down on the model aircraft shell, the electromagnet 25 is activated. The electromagnet 25 is energized and attracts the iron block 24. The iron block 24 drives the slider 23 to move downward. The air below the slider 23 is discharged through the vent 27. At the same time, a vacuum is drawn above the slider 23, thereby attracting the model aircraft shell and improving the stability of the model aircraft shell. The spring 26 is compressed, and the model aircraft shell comes into contact with the sealing ring 28. The sealing ring 28 can improve the sealing between the model aircraft shell and the support rod 10 and prevent air leakage above the slider 23.
