Description

Technical Field

[0001] This invention relates to the field of spraying fixture technology, and in particular to a spraying fixture for gas turbine transparent flat blades. Background Technology

[0002] Turbine blades, as a key core component of gas turbines, are difficult to manufacture and operate in complex and harsh environments, and have always been an important indicator of the level of heavy-duty gas turbines. To increase the turbine inlet temperature and improve the power generation efficiency of gas turbines, a thermal barrier protection layer needs to be coated on the surface of the turbine blades. Due to the large curvature and complex shape of heavy-duty gas turbine blades, and the presence of coated areas, transition areas, and prohibited coating areas on the blade surface, it is crucial to protect the prohibited coating areas during the coating process and strictly control the uniformity of the coating thickness in the coated and transition areas. The coated and transition areas should be coated, while the prohibited coating areas are not permitted to be coated.

[0003] Heavy-duty gas turbine turbine blades are typically installed in pairs, which can easily lead to obstruction between blades during painting. Furthermore, compared to aero-engine turbine blades, heavy-duty gas turbine turbine blades are significantly heavier, requiring strict control over blade fixation during painting. Additionally, the blade tip has a protective coating, and the surface of this coating near the blade also needs additional high-temperature coating protection. While existing automation technologies have optimized the painting trajectory for the complex curved surfaces of turbine blades, they cannot achieve perfect application of the thermal barrier coating to the surface of heavy-duty gas turbine turbine blades. There is a lack of suitable tooling fixtures for automated painting, which makes it difficult to guarantee precise positioning of the painting area and stable blade rotation during the painting process. Moreover, existing fixtures are mostly fixed to the painting platform using bolts, which hinders rapid installation and disassembly of the fixtures, severely impacting work efficiency. Therefore, we propose a gas turbine turbine blade painting tooling fixture to solve these problems. Summary of the Invention

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0029] Example 1

[0030] Reference Figure 1 This is the first embodiment of the present invention, which provides a spraying fixture for gas turbine turbine turbine blades. This device includes two sets of clamping mechanisms with identical structures and symmetrically arranged. The clamping mechanisms include…

[0031] The clamping unit 100 includes a rectangular base 101, an isolation strip 102 disposed on one side of the base 101, a support frame 103 disposed within the isolation strip 102, and multiple sets of fixing bolts 104 disposed on the isolation strip 102. The isolation strip 102 constitutes a barrier to prevent spraying and is welded and fixed to the base 101. The support frame 103 can fix objects located within the isolation strip 102 from multiple directions by converging from the outside to the inside of the isolation strip 102. The fixing bolts 104 serve to support the blades, so that there is a gap for air circulation between the base 101 and the blades, which accelerates the cooling and fixing of the paint.

[0032] The quick-connect unit 200 includes a fixing component 201 disposed on the other side of the base 101, an adjusting component 202 sleeved on the fixing component 201, a resetting component 203 disposed inside the lower part of the fixing component 201, and multiple sets of fastening components 204 evenly distributed in a ring on the fixing component 201. The fixing component 201 is fixedly connected to the side of the base 101 and its size is larger than the rotation axis of the spraying platform. The adjusting component 202 is threadedly connected to the fixing component 201. The fastening components 204 can clamp and fix objects located inside the fixing component 201 by applying inward pressure.

[0033] During use, the fixing component 201 is sleeved onto the rotating shaft of the spraying platform. The rotating adjustment component 202 forces multiple sets of fastening components 204 to clamp inward synchronously, thereby fixing the entire device onto the rotating shaft, allowing it to rotate coaxially with the rotating shaft. Then, one end of the blade to be sprayed is inserted into the isolation belt 102 and fixed by multiple sets of support frames 103 on the outside of the isolation belt 102. This limits its circumferential movement, preventing any circumferential movement. The synchronous relative movement of the two clamping mechanisms can effectively clamp and fix the blade to be sprayed. Through the quick-connect unit 200 rotating coaxially with the rotating shaft, the spray gun and the blade surface are precisely positioned at the spraying angle and distance. During rotation, the blade is kept stable and rotates at a uniform speed, realizing the automated spraying of the thermal barrier coating on the surface of the gas turbine blade.

[0034] Example 2

[0035] Reference Figures 1-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that it achieves effective clamping and fixing of the blade to be sprayed, ensures a perfect transition in coating thickness and uniformity between the surface coating area and the transition area, and effectively protects the prohibited spraying area, thereby improving production efficiency.

[0036] Compared to Example 1, the isolation strip 102 is further composed of six sets of baffles. The isolation strip 102, together with the base 101, forms a hollow cavity and a prohibited spraying zone X, which serves to protect and isolate the prohibited spraying area of ​​the transparent blade. When installing the fixture, a gap of 1-5mm is left between the six baffles of the isolation strip 102 and the blade, and they are not in complete contact, so that there is a channel for air circulation and exchange between them, thereby accelerating the cooling and fixing of the sprayed paint onto the blade.

[0037] During use, the fixing bolt 104 is L-shaped and welded between each pair of adjacent baffles of the isolation strip 102. When one end of the blade extends into the cavity formed by the isolation strip 102, it will first abut against the fixing bolt 104. Through the mutual squeezing and clamping of the tooling fixtures on both sides, the blade can be prevented from sinking and shifting due to its own weight during the spraying process, thus ensuring the spraying effect.

[0038] Among them, the six baffles of the isolation belt 102 adopt an arc surface design, are processed according to the geometric shape of the side of the transparent calm blade platform, and fit with the irregular curved surface of the platform. Each of the six baffles of the isolation belt 102 has two sets of threaded holes, and the fixing bolts 104 are threadedly connected in the threaded holes of the isolation belt 102.

[0039] During use, when one end of the transparent blade is located within the isolation zone 102, that end of the isolation zone 102 is a prohibited spraying area. Multiple sets of support frames 103 located on the isolation zone 102 can be moved closer to the interior of the isolation zone 102 by screwing them in. The inner end of the support frame 103 will eventually abut against the outer wall of the prohibited spraying end of the blade. Multiple sets of support frames 103 abut against the outer wall of the blade from different directions, which can limit its circumferential movement and prevent it from shifting to any side in the horizontal direction. This prevents the blade from having any problems during the spraying process and ensures the spraying effect.

[0040] The remaining structure is the same as that in Example 1.

[0041] Example 3

[0042] Reference Figures 2-6 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that it realizes the quick disassembly / assembly function of the tooling fixture and the rotating shaft of the spraying platform, thereby reducing the disassembly / assembly operation time and improving work efficiency.

[0043] Compared to Embodiment 2, the fixing component 201 further includes a fixing cylinder 201a with a tubular structure installed on the side of the base 101, and the fixing cylinder 201a has a threaded groove on its outer side, as well as multiple sets of limiting grooves 201b distributed in a ring on the fixing cylinder 201a, and multiple sets of fastening components 204 are arranged in the multiple sets of limiting grooves 201b in a one-to-one correspondence manner. The opening of the fixing cylinder 201a is flared, and its overall size is slightly larger than the rotating shaft of the spraying platform. Therefore, the fixing cylinder 201a can be easily fitted onto the rotating shaft.

[0044] The adjusting component 202 includes an adjusting ring 202a sleeved on the fixed cylinder 201a, multiple sets of hexagonal grooves 202b of different sizes opened on the adjusting ring 202a, and a limiting groove 202c opened inside the adjusting ring 202a. The limiting groove 202c extends inward through the inner wall of the adjusting ring 202a and has a semi-open structure. The inner wall of the adjusting ring 202a is provided with threaded teeth that match the outer wall of the fixed cylinder 201a. The hexagonal grooves 202b are slots of various sizes that can be matched with various types of hexagonal wrenches. By inserting the wrench, the adjusting component 202 can be rotated as a whole.

[0045] The reset component 203 includes a spring piece 203a located inside the fixed cylinder 201a, and a support spring 203b disposed between the spring piece 203a and the bottom surface of the fixed cylinder 201a. The spring piece 203a is elastically supported by the support spring 203b and will rise upward inside the fixed cylinder 201a. The outermost part of the spring piece 203a is attached to the inner wall of the fixed cylinder 201a.

[0046] Furthermore, the fastening component 204 includes a support component 204a located in the limiting groove 201b, an abutment component 204b rotatably connected to the top of the support component 204a, and a pressing component 204c disposed on one side below the support component 204a and extending one end into the limiting groove 202c. The support component 204a located in the limiting groove 201b is limited by its two sides and can only move on a trajectory that coincides with the limiting groove 201b.

[0047] The support assembly 204a includes a support plate 204a-1 located in the limiting groove 201b, a first rotating shaft 204a-2 disposed at the bottom end of the support plate 204a-1 and extending to both sides into the fixed cylinder 201a, a second rotating shaft 204a-3 disposed at the top end of the support plate 204a-1 and rotatably connected to the abutment assembly 204b on the second rotating shaft 204a-3, an oblique edge 204a-4 obliquely opened on the outside of the support plate 204a-1, and a straight edge 204a-5 opened on the lower inner side of the support plate 204a-1 and parallel to the inner wall of the adjusting ring 202a.

[0048] Furthermore, one end of the extrusion assembly 204c abuts against the outer side of the inclined edge 204a-4, the straight edge 204a-5 is parallel to the inner wall of the fixed cylinder 201a in the normal state, the outer side of the spring piece 203a abuts against the straight edge 204a-5, and the support assembly 204a is rotatably connected to the fixed cylinder 201a through the first rotating shaft 204a-2, and can rotate with the first rotating shaft 204a-2 as the axis.

[0049] Furthermore, the abutment component 204b includes an abutment plate 204b-1 located on the side of the support component 204a and parallel to it, a rotating ear 204b-2 disposed between the support plate 204a-1 and the abutment plate 204b-1 and rotatably connected to the second rotating shaft 204a-3, and a friction block 204b-3 vertically formed on one side of the abutment plate 204b-1.

[0050] During use, the vertical opening of the friction block 204b-3 increases the circumferential friction between the abutting component 204b and the rotating shaft when the abutting component 204b abuts against the outer wall of the rotating shaft, thereby making the connection between the device and the rotating shaft tighter.

[0051] Furthermore, the extrusion assembly 204c includes a push rod 204c-1 located in the limiting groove 202c, and a limiting ball 204c-2 disposed at the end of the push rod 204c-1, wherein the diameter of the limiting ball 204c-2 is larger than the width of the push rod 204c-1. One end of the push rod 204c-1 extends into the limiting groove 201b and is limited by the limiting groove 201b, so it can only slide vertically within the limiting groove 201b. Since the limiting ball 204c-2 is located in the hexagonal groove 202b, the adjusting component 202 can drive the extrusion assembly 204c to move vertically.

[0052] During use, the rotating shaft extends into the fixed cylinder 201a, compressing the spring 203a and causing it to slide downwards to the bottom of the fixed cylinder 201a. At this time, the support spring 203b contracts and stores energy, while multiple sets of abutment components 204b located on the fixed cylinder 201a surround the outside of the rotating shaft from multiple directions. Then, the adjusting component 202 is rotated, and the adjusting component 202 spirals upwards along the outer wall of the fixed cylinder 201a, driving the compression component 204c to move. The upward-moving compression component 204c compresses the side of the support component 204a. Since the extrusion component 204c moves in a parallel posture, the extruded support component 204a will rotate around the first rotating shaft 204a-2. The rotating support component 204a will push the top abutment component 204b to gradually approach the outer wall of the rotating shaft. Finally, as the adjustment component 202 continues to move, the multiple sets of abutment components 204b surrounding the outside of the rotating shaft will firmly abut against the outer wall of the rotating shaft, thereby making the whole device firmly connected to the rotating shaft, so that the device can rotate synchronously with the rotating shaft.

[0053] Conversely, rotating the adjusting component 202 in the opposite direction will cause the pressing component 204c to slide downward, releasing the pressure on the fastening component 204. This will cause the abutment component 204b to no longer abut against the rotating shaft, allowing the two to easily separate. When the rotating shaft is completely pulled out of the fixed cylinder 201a, the pressure on the spring 203a will disappear, and the support spring 203b will rebound and lift it up. The edge of the spring 203a will abut against the straight edge 204a-5, causing the support component 204a to rotate outward about the first rotating shaft 204a-2 as the axis, and finally causing the support component 204a to retract into the limiting groove 201b, thereby realizing the function of resetting the fastening component 204 as a whole.

[0054] The remaining structure is the same as that in Example 2.
