Description

Technical Field

[0001] The utility model relates to the field of positioning devices, in particular to an adjusting and positioning device for processing gas turbine seals. Background Art

[0002] Gas turbine seals are an important component in ensuring efficient and reliable operation of gas turbines. The adjustment and positioning devices in seal processing are important equipment to ensure processing accuracy and efficiency. These devices are used to accurately position seals during the processing and make necessary adjustments. They can avoid shaking or offsetting of seals during processing, which can significantly improve the production quality of seals and reduce production costs.

[0003] However, most of the current adjustment and positioning devices used in gas turbine seal processing have the following problems:

[0004] For example, a seal positioning device with publication number CN221210685U can position and process the seal through movable rings on both sides, but the arc shape of the seal movable ring is in a fixed state. If it is necessary to clamp and process seals of different sizes and models, it is easy to be unable to limit the position, which is inconvenient to clamp and position seals of different sizes and models. At the same time, after the seal is clamped and limited, if the other side of the seal needs to be processed, it is necessary to loosen the clamped seal, take out the seal, turn it over and re-clamp it. The turning operation is more troublesome, and it is inconvenient to perform convenient turning processing on the clamped seal.

[0005] Therefore, we have made improvements to this problem and proposed an adjustment and positioning device for gas turbine seal processing. Utility Model Content

[0006] The purpose of the utility model is to solve the existing problems of inconvenience in clamping and positioning seals of different sizes and models, and inconvenience in conveniently turning over the clamped seals.

[0007] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0008] An adjusting and positioning device is provided for processing gas turbine seals to improve the above problems.

[0009] The specific application is as follows:

[0010] The gear train is connected with the gear train by the two ends of the chain, and the gear train is connected with the two ends of the chain. The gear train is connected with the two ends of the chain. When the gear train is turned, the two ends of the chain are rotated to form a circle, and the two ends of the chain are connected with the belt. When the gear train is turned, the two ends of the chain are rotated to form a circle. When the gear train is turned, the two ends of the chain are rotated to form a circle.

[0011] As a preferred technical solution of the present application, the output shaft of the electric motor is fixedly connected to the center of one end of the bidirectional threaded rod, and the side end surface of the moving block is in contact with the inner side surface of the fixing frame.

[0012] As a preferred technical solution of the present application, the moving blocks are symmetrically distributed on the left and right sides of the bidirectional threaded rod, and the moving blocks correspond one to one with the push plates.

[0013] As a preferred technical solution of the present application, the connecting shaft is fixedly connected to the center portion of the inner side of the fixed box, and the springs are symmetrically distributed on the left and right sides of the fixed box.

[0014] As a preferred technical solution of the present application, a clamping rod is fixedly connected to the limit plate, a pull rod is fixedly connected to the limit plate, and a side end surface of the limit plate is in contact with the inner side surface of the fixed box.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the scheme of this application:

[0017] 1. A bidirectional threaded rod is provided; when clamping seals of different sizes, the seals can be placed in the fixed frame, and the electric motor is turned on to drive the bidirectional threaded rod to operate. When the bidirectional threaded rod rotates, the bidirectional threaded rods on both sides can be driven to rotate simultaneously through the pulley and the synchronous toothed belt. When the bidirectional threaded rod rotates, it can drive the moving blocks on both sides to move. When the moving blocks on both sides move inward at the same time, the moving blocks can push the splint to move through the push plate. When the splints on both sides move inward, the splint can cooperate with the anti-slip pad to limit and clamp the seal, which can clamp and limit seals of different sizes, thereby improving the positioning processing effect.

[0018] 2. A connecting shaft is provided; when the seal installed on the fixed frame needs to be turned over, the pull rod can be pulled to drive the limit plate to move. The limit plate can squeeze the spring when moving. At the same time, the limit plate can drive the clamping rod to disengage from the workbench and the fixed frame and retract it into the fixed box. After there is no obstruction, the fixed box can be rotated to drive the fixed frame on the connecting shaft to rotate, so as to turn over the seal installed on the fixed frame. After the turning over is completed, the pull rod is released, and the limit plate and the clamping rod are reset under the push of the spring, which can drive the clamping rod to engage between the workbench and the fixed frame, and engage and position the turned-over fixed frame to avoid shaking after turning over.

[0031] Example 2:

[0032] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0033] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, the output shaft of the electric motor 5 is fixedly connected to the center part of one end of the bidirectional threaded rod 6, and the side end face of the moving block 9 is in contact with the inner side face of the fixed frame 4, which can ensure that when the moving block 9 moves, the moving block 9 can move smoothly through the support of the inner side face of the fixed frame 4.

[0034] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, the moving blocks 9 are symmetrically distributed on the left and right sides of the bidirectional threaded rod 6, and the moving blocks 9 correspond to the push plates 10 one by one, which can ensure that when the push plates 10 on both sides move, they can smoothly push the clamping plates 11 to move and play a clamping role.

[0035] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the connecting shaft 3 is fixedly connected to the inner center of the fixed box 13, and the springs 14 are symmetrically distributed on the left and right sides of the fixed box 13, which can ensure that the limit plate 15 can be smoothly pushed to move under the push of the springs 14 on both sides.

[0036] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, a clamping rod 16 is fixedly connected to the limit plate 15, and a pull rod 17 is fixedly connected to the limit plate 15.
