Description

Technical Field

[0001] The utility model belongs to the technical field of deposition coatings, in particular to a surface coating tooling device. Background Art

[0002] With the development of science and technology in the fields of aerospace and electronic information, the surface chemical vapor deposition coating process has been more widely used and the demand is also increasing. Therefore, it is of great significance to improve the surface quality and uniformity of the workpiece surface coating. Chemical vapor deposition is a chemical technology that mainly uses one or several gas phase compounds or single substances containing film elements to chemically react on the surface of the substrate to form a film. Since the 1980s, NASA has begun to try to use metal organic compound chemical vapor deposition to produce a composite nozzle using rhenium-based iridium as a coating, and has achieved success. At this time, chemical vapor deposition has made a certain degree of breakthrough in the field of producing precious metal coatings. In traditional technologies, different methods of surface chemical vapor deposition coatings have great differences. There are generally problems of poor uniformity of sprayed surface coatings and low production efficiency, which affects the development of this technology. Utility Model Content

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail in combination with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solution of the present invention is described in detail below in combination with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0020] Example 1

[0021] like Figure 1-2As shown, this embodiment provides a surface coating auxiliary tooling, which is arranged in a high-temperature furnace, and includes a fixed rod 1, a movable rod 2, a workpiece 3, a top plate 4, a first support block 5, a fixed plate 6, a movable plate 7, a base 8, a first locking bolt 9, a sealing ring 10, a second locking bolt 11, a sealing ring bolt 12, a nut 13, and a guide block 14.

[0022] The lower part of the base 8 is connected to a motor and a lead screw component, and the motor and the lead screw rotating component are commonly used equipment structures in the field. Figure 1 The base 8 is connected to the motor, so that the whole tooling can perform circular motion.

[0023] The movable plate 7 is movably connected to the base 8, and the movable plate 7 is fixed to the sealing ring 10 by a sealing ring bolt 12. The base 8 is provided with a sealing groove, and when the movable plate 7 is in contact with the base 8, the sealing ring 10 is embedded in the sealing groove.

[0024] The two movable rods 2 are fixedly connected to both sides of the movable plate 7 by second locking bolts 11. A screw component is connected to the bottom of the movable plate 7, and the screw component is connected to a driving motor. After the screw component moves up and down, the movable plate 7 component is lifted or lowered, thereby driving the movable rods 2 to move up and down.

[0025] A guide block 14 is connected to the base 8, and the movable plate 7 is slidably connected to the guide block 14 to ensure that the movable plate 7 moves stably along the guide block 14. The top of the guide block 14 is connected to the fixed plate 6 through the first locking bolt 9, and the fixed plate 6 is located above the movable plate 7. Both sides of the fixed plate 6 are connected to a fixed rod 1 through a nut 13 respectively, and a square structure is formed between the two fixed rods 1 and the two movable rods 2, and the workpiece 3 is located between the two fixed rods 1 and the two movable rods 2. A first support block 5 is arranged on the inner side of the fixed rod 1, and a second support block 15 is arranged on the inner side of the movable rod 2. The first support block 5 and the second support block 15 have the same structure, including a connected oblique rod and a vertical rod, one end of the oblique rod is connected to the movable rod 2 or the fixed rod 1, and one end of the vertical rod is used to support the workpiece 3. The position of the first support block 5 is higher than the second support block 15.

[0026] A top plate 4 is connected to the top of the fixed rod 1, and the movable rod 2 is movably connected to the top plate 4. The top plate 4 constrains the fixed rod 1 and the movable rod 2 so that they do not move eccentrically during the circular motion.

[0027] The working principle of this tooling device is:

[0028] The motor connected to the bottom of the base 8 drives the entire tooling to rotate, which can ensure that the surface of the workpiece 3 is evenly coated with material; the workpiece 3 is first supported by the first support block 5 for spraying, and then the movable plate 7, driven by the screw component, causes the movable rod 2 to rise, and the two ends of the workpiece 3 are supported by the second support block 15. During further spraying, the unsprayed position at the supporting point of the first support block 5 can be further sprayed, ensuring comprehensive spraying; after the second support block 15 contacts the workpiece 3, it supports the workpiece 3 and lifts it to a certain height, and this action is subsequently repeated.

[0029] Example 2

[0030] The overall structure is the same as that of Embodiment 1, except that there is only one movable rod 2, and the vertical rod part of the second supporting block 15 is supported at the center position of the workpiece 3 to ensure that the workpiece 3 is stably supported.

[0031] The above content is a further detailed description of the utility model in combination with a specific preferred implementation method. It cannot be determined that the specific implementation methods of the utility model are limited to this. For ordinary technicians in the technical field to which the utility model belongs, they can make several simple deductions or substitutions without departing from the utility model, which should be regarded as belonging to the utility model and the scope of patent protection determined by the submitted claims.
