Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and more specifically to a clamping fixture for plasma-sprayed parts. Background Technology

[0002] Plasma spraying is a thermal spraying technology. Its principle is to use the ultra-high temperature plasma jet generated by electric arc discharge to instantly heat the powdered "coating material" such as metal, ceramic, and alloy to a molten / semi-molten state, and then spray it onto the "target substrate surface" at high speed (hundreds of meters per second). Finally, it cools and solidifies to form a dense and uniform functional coating. The core purpose of plasma spraying on the target is to optimize the service performance of the target, extend its service life, or endow it with special functions by constructing a high-performance coating, so as to meet the stringent requirements of the target material in high-end coating fields such as semiconductors, display panels, and photovoltaics.

[0003] The size and specifications of the target materials usually vary. In the process of spraying different target materials, it may be necessary to change the clamp in order to hold the target material stably, which not only increases the cost but also reduces the work efficiency.

[0004] Therefore, it is necessary to propose a plasma-sprayed parts clamping fixture to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4. A plasma-sprayed parts clamping fixture includes a first support 3, a second support 4, and a chuck 1. Multiple telescopic grooves 10 are evenly distributed on the top surface of one end of the chuck 1. Clamping rods 5 are movably sleeved in each telescopic groove 10. A first hydraulic cylinder 8 is fixedly connected to the center of the end of the chuck 1. The telescopic rod end of the first hydraulic cylinder 8 is located in the inner cavity of the chuck 1. A push rod assembly 12 is movably sleeved at the other end of the telescopic groove 10. A pressure sensor 13 is fixedly connected to the center of one end of the push rod assembly 12. The end of the first hydraulic cylinder 8 is fixedly connected to the pressure sensor 13. A compression spring 11 is provided between the push rod assembly 12 and the clamping rods 5. A cover plate 15 is provided at the front end of the chuck 1.

[0023] The bottom surface of the cover plate 15 is evenly provided with slots 14 corresponding to the telescopic groove 10. Both sides of the cover plate 15 are symmetrically rotatably connected with connecting rods 6. The lower end of the connecting rod 6 is rotatably connected to both sides of the clamp 1. The side plate of the clamp 1 is rotatably connected with a second hydraulic cylinder 7. The telescopic rod end of the second hydraulic cylinder 7 is rotatably connected to one side of the cover plate 15. The second hydraulic cylinder 7 is inclined. The connecting rod 6, the cover plate 15 and the clamp 1 form a parallelogram structure.

[0024] The front end of the card slot 14 is provided with an anti-slip pad 16. The anti-slip pad 16 is made of rubber or other anti-slip material, which can increase friction and ensure the stability of clamping.

[0025] The end of the second bracket 4 away from the chuck 1 is movably sleeved inside the first bracket 3. A third hydraulic cylinder 2 is fixedly connected to the top surface of the first bracket 3. The telescopic rod end of the third hydraulic cylinder 2 is fixedly connected to the second bracket 4. The device can be fixed to the rotary joint or other work positions through the first bracket 3.

[0026] Working principle: In this invention, when clamping materials, the telescopic rod of the second hydraulic cylinder 7 is in an extended state, and the clamping rod 5 can move freely. The third hydraulic cylinder 2 drives the two clamps 1 to move closer to each other. According to the shape and size of the material, the clamping rod 5 in contact with the material will retract inward. Then, the first hydraulic cylinder 8 pushes the top rod assembly 12 to pressurize the compression spring 11. The pressure sensor value is set according to the actual situation. When the requirement is met or the compression spring 11 is contracted to its limit, it indicates that the material is clamped. Then, the second hydraulic cylinder 7 retracts and presses the cover plate 15 downward to fix the clamping rod 5 in a fixed state, ensuring the stability of the clamping. Then, the coating is applied.
