Description

Technical Field

[0001] This utility model relates to the field of turbine blade technology, and specifically to a tooling for processing a surface coating on turbine blades. Background Technology

[0002] As modern high-performance aero-engines achieve increasingly higher thrust-to-weight ratios and decrease the proportion of available cool gas flow, their turbine blades endure increasingly higher temperatures and pressures. Therefore, relying solely on the blade alloy itself and air-molded cooling technology is no longer sufficient to meet operational requirements. Applying PVD coating technology to aero-engine turbine blades can significantly improve the turbine blade material's resistance to high-temperature oxidation and hot corrosion.

[0003] Announcement No. CN221416385U discloses a turbine blade machining fixture, including a base. A guide rail is fixedly connected to one side of the upper surface of the base. A sliding sleeve is slidably connected to the upper surface of the guide rail, and a first vertical plate is fixedly connected to the upper surface of the sliding sleeve. A first clamping assembly is provided at the top of the first vertical plate. A second vertical plate is fixedly connected to the upper surface of the base away from the guide rail, and a second clamping assembly is provided at the top of the second vertical plate. In this utility model, a base, guide rail, first vertical plate, first clamping assembly, second vertical plate, second clamping assembly, and air pump are provided. After the first vertical plate is moved a certain distance along the guide rail, air is pumped into the second clamping assembly by the air pump, causing multiple second push rods of the second clamping assembly to move. In conjunction with the multiple first push rods of the first clamping assembly, various turbine blades of different shapes can be clamped and fixed, improving the versatility of the fixture.

[0004] The aforementioned problems are as follows: Although the tooling can clamp and fix turbine blades of various shapes, improving its versatility, there is no matching positioning tooling for the turbine blades when they rotate, which can easily lead to the peeling off of the coating on the surface of the turbine blades, thereby reducing the coating efficiency. Therefore, a turbine blade surface coating processing tooling is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a tooling for processing surface coatings on turbine blades, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A turbine blade surface coating processing fixture includes a support plate, a motor mounted on the top of the support plate, a rotating rod fixedly connected to the output end of the motor, two sets of gears fixedly connected to the outer wall of the rotating rod, a connecting plate fixedly connected to the top of the rotating rod, and a positioning fixture for synchronously positioning the turbine blade at the bottom of the connecting plate. The positioning fixture includes a fixed frame, a limit block fixedly connected to the bottom of the fixed frame, a moving groove formed inside the limit block, a moving block slidably connected inside the moving groove, a rack fixedly connected to one side of the moving block, one side of the rack meshing with one side of the gear, a connecting frame fixedly connected to one side of the rack, and a positioning block fixedly connected to one side of the connecting frame. The interior of the positioning block contacts the outer wall of the turbine blade, and a replacement component for replacing the positioning block is provided inside the positioning block.

[0008] The above technical solution involves the interaction of a rotating rod, a motor, a connecting plate, a limiting block, a moving groove, a moving block, a rack, and a gear. The output of the motor drives the rotating rod to rotate, which in turn drives the gear to rotate. The meshing of the gear and rack causes the rack to move laterally through the moving block inside the moving groove. Simultaneously, the rack drives the connecting frame and the positioning block to move towards the turbine blade through the slider inside the groove. When the inside of the positioning block contacts the outer wall of the turbine blade, the turbine blade can be positioned, thus improving stability.

[0009] A further improvement of this utility model is that: a sliding groove is provided on the top of the connecting plate, and a slider is slidably connected inside the sliding groove, with the top of the slider and the bottom of the positioning block being fixedly connected.

[0010] By adopting the above technical solution, the sliding groove and the slider are designed to cooperate with each other. The sliding groove can limit the slider, which can prevent the slider from deviating during sliding, thus achieving the goal of limiting the slider and improving stability.

[0011] A further improvement of this utility model is that a limiting frame is fixedly connected to the top of the support plate, and the interior of the limiting frame is rotatably connected to the outer wall of the rotating rod.

[0012] By adopting the above technical solution, the rotating rod can rotate inside the limiting frame through the cooperation of the limiting frame and the rotating rod, which avoids the rotating rod from falling off during rotation, thus limiting the rotating rod and improving stability.

[0013] A further improvement of the present invention is that the positioning fixture further includes a chain, and a sprocket is fixedly connected to the outer wall of the rotating rod, with the outer wall of the sprocket and the inner wall of the sprocket meshing.

[0014] By adopting the above technical solution, the chain and sprocket are set up to cooperate with each other. The rotating rod will drive the sprocket to rotate, and the meshing of the sprocket and chain will drive the two sets of rotating rods to rotate simultaneously, thereby realizing the simultaneous driving of the two sets of rotating rods and improving the processing efficiency.

[0015] A further improvement of this utility model is that a fixing block is fixedly connected to the top of the connecting disk, and the interior of the fixing block is in contact with the outer wall of the turbine blade.

[0016] By adopting the above technical solution, the fixed block and the positioning block cooperate with each other to position the turbine blade, thereby improving the spraying efficiency.

[0017] A further improvement of this utility model is that the replacement component includes screw holes, all of which are provided inside the connecting frame and the positioning block. Bolts are threaded into the screw holes, and the interior of the connecting frame and the interior of the positioning block are detachably connected by bolts.

[0018] By adopting the above technical solution, the user can separate the bolt and the inside of the screw hole by setting up the screw hole, bolt and positioning block. Then the user can take out the positioning block, which realizes the maintenance and replacement of the positioning block and improves the practicality.

[0019] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared with the prior art is that it enables the positioning of turbine blades and improves stability.

[0020] 1. This utility model provides a tooling for processing surface coating on turbine blades. By setting up a rotating rod, a motor, a connecting plate, a limiting block, a moving groove, a moving block, a rack, and a gear in mutual cooperation, the output end of the motor drives the rotating rod to rotate, the rotating rod drives the gear to rotate, and the meshing of the gear and the rack drives the rack to move laterally inside the moving groove through the moving block. At the same time, the rack drives the connecting frame and the positioning block to move towards the side closer to the turbine blade inside the sliding groove through the slider. When the inside of the positioning block contacts the outer wall of the turbine blade, the turbine blade can be positioned, improving stability.

[0021] 2. This utility model provides a tooling for processing the surface coating of turbine blades. By setting up screw holes, bolts and positioning blocks in cooperation, the user can separate the inside of the bolts and screw holes with relevant tools, and then the user can take out the positioning blocks, which enables the maintenance and replacement of the positioning blocks and improves practicality.
