[0002] The turbine blade is a core component in turbomachinery (such as gas turbines, aeroengines, steam turbines, etc.), mainly used to guide the fluid to flow in a certain direction and drive the rotor to rotate to achieve energy conversion.

[0003] The existing support for gas turbine turbine blades is mostly a fixture machined according to the shape of the blade tenon. For example, in the Chinese invention patent with the patent number CN202310547483.6, there are a series of special processing requirements for semi-finished castings (the blade tenons are not machined). During the processing, the blade needs to be supported vertically forward and vertically inverted. The existing fixture structure is relatively complex and difficult to meet the requirements of both vertical forward support and vertical inverted support. Summary of the Utility Model

[0004] In view of the problem that the support angle of the support mechanism is not easy to adjust in the above or existing technology, the present utility model is proposed.

[0005] Therefore, the purpose of the present utility model is to provide a support mechanism.

[0030] To make the above-mentioned objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0031] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0032] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0033] Embodiment 1, referring to Figures 1 to 6 , which is the first embodiment of the present utility model. This embodiment provides a support mechanism that can adjust the support angle according to the supported surface of the blade, making the mechanism fit more closely with the blade and providing a stable support for the blade.

[0034] The support mechanism includes a support member 100, and the support member 100 includes a support rod 101. The support rod 101 serves as a connection between the upper and lower parts and provides a vertical support space for the blade. The specific shape of the cross-section of the support rod 101 is not limited herein; a threaded surface is processed at the bottom of the support rod 101, and the threaded surface is used for fixedly connecting with the base 201; a connection assembly 102 is arranged on the top surface of the support rod 101. The connection assembly 102 is adapted to rotate in two directions, horizontal and vertical, to cooperate with the supported surface of the blade; a support member 103 is arranged on the top of the connection assembly 102. The support member 103 is used to contact the blade and can be set as a cuboid structure, a plate-like structure, etc., as long as it can support the blade, and the specific structure is not limited herein.

[0035] Specifically, the connection assembly 102 includes a receiving cover 102b and a connection core 102a arranged in the receiving cover 102b. The connection core 102a can rotate within the receiving cover 102b.

[0036] Further, the connection core 102a is set as a sphere, and the spherical shape is more conducive to the hinged cooperation between the connection core 102a and the receiving cover 102b.

[0037] Among them, the receiving cover 102b is set as a cavity with openings at both ends. A first opening 102b-1 is arranged at the top of the receiving cover 102b, and a second opening 102b-2 is arranged at the bottom of the receiving cover 102b. The first opening 102b-1 allows a part of the connection core 102a to extend out; specifically, about one-fourth of the height of the connection core 102a extends out through the first opening 102b-1. The extended part of the connection core 102a is fixedly connected with the support member 103, and the support member 103 drives the connection core 102a to rotate.

[0038] Preferably, a limiting inner wall 102b-3 is arranged on the inner side wall of the receiving cover 102b near the first opening 102b-1. The height of the limiting inner wall 102b-3 is approximately equal to 1 / 3 of the total inner height of the receiving cover 102b. The arc surface of the limiting inner wall 102b-3 fits with the circular surface of the connection core 102a, so that the two form a partial hinged contact, and the connection core 102a can rotate freely relative to the limiting inner wall 102b-3.

[0039] It should be noted that a receiving cavity 101a is arranged on the top wall of the support rod 101, and a threaded surface is processed on the inner side wall of the receiving cavity 101a; an external threaded surface is processed on the outer side wall of the second opening 102b-2 of the receiving cover 102b to realize the screwed and fixed connection between the receiving cover 102b and the support rod 101.

[0040] The connection core 102a is inserted into the receiving cover 102b from the second opening 102b-2, and then the receiving cover 102b is fixedly connected with the support rod 101. Furthermore, the connection core 102a is fixed between the receiving cavity 101a and the receiving cover 102b.

[0041] It should be noted that after the receiving cover 102b is assembled with the support rod 101, the height between the receiving cover 102b and the receiving cavity 101a is slightly greater than the diameter of the connecting core 102a, so as to prevent the connecting core 102a from being stuck after being fixed in the receiving cavity 101a and the receiving cover 102b, resulting in the inability of the connecting core 102a to rotate.

[0042] Furthermore, a threaded hole 102a-1 is provided on the connecting core 102a, and the threaded hole 102a-1 is used for threaded connection with the support member 103.

[0043] During the assembly process of this mechanism, it should be noted that first, a bolt is screwed into the threaded hole 102a-1, and then the connecting core 102a is placed into the receiving cover 102b along the first opening 102b-1, ensuring that the bolt extends out along the first opening 102b-1 to ensure that the threaded hole 102a-1 extends out along the first opening 102b-1; then the receiving cover 102b is fixedly connected to the support rod 101 to complete the assembly of this mechanism.

[0044] In summary, since the connecting core 102a is limited by the receiving cover 102b and the receiving cavity 101a and forms a hinge with the limiting inner wall 102b-3, the connecting core 102a can rotate freely within the range of the first opening 102b-1, which further facilitates the fitting of the support member 103 with the blade.

[0045] Example 2, referring to Figure 7 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides another structure of the connecting component 102.

[0046] Among them, the connecting component 102 includes a support spring 102c.

[0047] Specifically, the support spring 102c is welded between the support rod 101 and the support member 103. When the support member 103 supports the blade, the support spring 102c can appropriately tilt the support angle of the support member 103 due to its own telescopic space.

[0048] The remaining structures are the same as those in Example 1.

[0049] Example 3, referring to Figures 8 to 9 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a support tool for gas turbine turbine blades, which solves the problem of vertical support of gas turbine turbine blades and includes the support mechanism in the above embodiment.

[0050] The gas turbine turbine blade support tooling includes a fixing component 200. The fixing component 200 includes a base 201 and a sleeve 202 provided on the base 201. The sleeve 202 is adapted to the support rod 101.

[0051] Specifically, several sleeves 202 are provided and are pre-set at different positions on the base 201 according to common blade sizes. When it is necessary to support the blade, select three sleeves 202 at corresponding positions, and then screw and fix the three support rods 101 into the selected sleeves 202 respectively to complete the installation of this device.

[0052] Furthermore, a positioning pin 203 is provided on the sleeve 202. The positioning pin 203 is perpendicular to the side wall of the sleeve 202 and can be screwed into the sleeve 202 through the side wall of the sleeve 202. The threaded surface at the bottom of the support rod 101 is screwed into the sleeve 202. By screwing the support rod 101 up and down, the height of the support rod 101 can be adjusted. After the height is adjusted appropriately, screw the positioning pin 203 into the sleeve 202 and abut it against the side wall of the support rod 101 to further fix the position of the support rod 101.

[0053] The remaining structures are the same as those in Embodiment 2.

[0054] When in use, first select three sleeves 202 at corresponding positions according to the size of the blade to be supported. Unscrew the positioning pins 203 on the corresponding sleeves from the side walls of the sleeves 202. Screw the three support rods 101 into the selected sleeves 202 respectively. By screwing the support rods 101 up and down, make the heights of the three support rods 101 consistent. Then screw the positioning pins 203 into the sleeves and abut them against the side walls of the support rods 101 to further fix the positions of the support rods 101.

[0055] Finally, place the blade that needs to be vertically supported in the middle of the three support rods 101. Under the action of the connecting component 102, the support members 103 on the top surfaces of the support rods 101 change the corresponding support angles as the shape of the supported position of the blade changes.

[0056] In summary, through the setting of different positions of the sleeves 202 in this support tooling, the blade support tooling has better adaptability and can be applied to blades of different sizes; through the setting of the connecting component 102, this device can better adapt to blades of different shapes.

[0057] Importantly, it should be noted that the construction and arrangement of the present application shown in multiple different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who refer to this disclosure should easily understand that many modifications are possible without substantially departing from the novel teachings and advantages of the subject matter described in this application (for example, the dimensions, scales, structures, shapes and proportions of various elements, as well as parameter values (such as temperature, pressure, etc.), installation arrangements, use of materials, color, changes in orientation, etc.). For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of the element may be inverted or otherwise changed, and the nature, number or position of discrete elements may be altered or changed. Therefore, all such modifications are intended to be included within the scope of the present utility model. The order or sequence of any process or method steps may be changed or reordered according to alternative embodiments.

Other substitutions, modifications, changes and omissions may be made in the design, operating conditions and arrangement of the exemplary embodiments without departing from the scope of the present utility model. Therefore, the present utility model is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.

[0058] In addition, in order to provide a concise description of the exemplary embodiments, not all features of the actual embodiments may be described (i.e., those features that are not relevant to the currently considered best mode of implementing the present utility model or those features that are not relevant to the implementation of the present utility model).
