Description

Technical Field

[0001] This utility model belongs to the field of fixture technology, and in particular relates to an auxiliary cutting fixture for turbine blade processing. Background Technology

[0002] The turbine rotor is the main rotating part of machines such as steam compressors and turbochargers. The turbine blades are assembled with the mortise and tenon on the turbine rotor to form a combined turbine rotor. During production, the size of the turbine blades varies depending on the machine model. Therefore, the turbine blades need to be cut by cutting equipment. In order to ensure accurate cutting, the turbine blades need to be stably fixed to ensure the accuracy of the cutting.

[0003] Most existing turbine blade cutting auxiliary fixtures are fixed clamps, which fix the cutting direction. When multiple surfaces of the turbine blade need to be cut, they need to be removed and then clamped again, which is cumbersome and has low work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary cutting fixture for turbine blade processing, which solves the problem that most existing auxiliary cutting fixtures for turbine blades are fixed clamps, which fix the cutting direction. When multiple surfaces of the turbine blade need to be cut, they need to be removed and then clamped again, which is cumbersome and has low work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an auxiliary cutting fixture for turbine blade processing, comprising a base and a fixture assembly. The base is U-shaped, with a fixed block fixedly connected to one end and a sliding groove formed at the other end. The fixture assembly includes a linkage block disposed on the surface of the other end of the base and slidably connected to it. A slider is fixedly connected to the bottom end of the linkage block and is disposed within the sliding groove, engaging with it. A linkage rod is rotatably connected inside the linkage block, and a rotating rod is rotatably connected inside the fixed block. One end of the linkage rod and the rotating rod are threadedly connected to a contour chuck, which is positioned above the base. A positioning circular plate is fixedly connected to the periphery of the other end of the linkage rod, positioned outside the linkage block.

[0007] The positioning circular plate has several positioning grooves evenly distributed on its circumferential side. Connecting blocks are fixedly connected to both sides of one surface of the linkage block. A connecting rod is rotatably connected between the two sets of connecting blocks. The connecting rod is located below the positioning circular plate. A limiting block is fixedly connected to the circumferential side of the connecting rod. The limiting block is engaged with the positioning groove.

[0008] One end of the connecting rod is fixedly connected to a connecting plate, the connecting plate is disposed on one side of the connecting block, a swing rod is fixedly connected to one surface of the connecting plate, a positioning screw is disposed inside the swing rod, and one end of the positioning screw is threadedly connected to the linkage block.

[0009] A mounting bracket is fixedly connected to one side of the base. A servo motor is installed inside the mounting bracket. A threaded rod is fixedly connected to the output end of the servo motor. The threaded rod is set in a slide groove and rotates with the slide groove. The slider is set on the periphery of the threaded rod and threadedly engages with the threaded rod.

[0010] The other end of the linkage rod is fixedly connected to a rotating handle, which is located on one side of the positioning circular plate. By setting the rotating handle, it is convenient to rotate the linkage rod, thereby adjusting the direction of the clamped turbine blade and facilitating multi-faceted processing of the turbine blade.

[0011] This utility model has the following beneficial effects:

[0012] This invention utilizes a base and clamping assembly to place the turbine blade to be processed between two sets of contour chucks. A servo motor drives a slider via a threaded rod, which in turn moves a linkage block, allowing the two sets of contour chucks to clamp and fix the turbine blade. The contour chucks, linkage rod, and rotating rod are all threadedly connected, allowing for customization based on the required turbine blade size for better clamping. After clamping and fixing, when multi-faceted processing and cutting of the turbine blade is required, the positioning screw is tightened to release the constraint from the linkage block. This allows the connecting rod to rotate via a swing rod and connecting plate, separating the limit block from the positioning plate. Rotating the handle then rotates the linkage rod, adjusting the direction of the clamped turbine blade. The limit block is then swung back to its original position, engaging with the positioning plate. The positioning screw reinforces the limiting performance of the limit block, ensuring clamping stability. This allows for multi-faceted processing and cutting of the turbine blade. The structure is simple and the operation is convenient.

[0023] Please see Figures 1-3As shown, this utility model is an auxiliary cutting fixture for turbine blade processing, including a base 1 and a fixture assembly 2. The base 1 is U-shaped, with a fixing block 101 fixedly connected to one end of the base 1 and a sliding groove 102 opened at the other end of the base 1. The fixture assembly 2 includes a linkage block 201, which is disposed on the surface of the other end of the base 1 and slidably connected to the base 1. A slider 204 is fixedly connected to the bottom end of the linkage block 201, which is disposed in the sliding groove 102 and slidably engaged with the sliding groove 102. A linkage rod 202 is rotatably connected inside the linkage block 201, and a rotating rod is rotatably connected inside the fixing block 101. A contour chuck 203 is threadedly connected to one end of the linkage rod 202 and the rotating rod, respectively. The contour chuck 203 is disposed above the base 1. A positioning circular plate 205 is fixedly connected to the periphery of the other end of the linkage rod 202, which is disposed outside the linkage block 201.

[0024] The positioning circular plate 205 has several positioning grooves evenly distributed on its circumferential side. Connecting blocks 206 are fixedly connected to both sides of one surface of the linkage block 201. A connecting rod 207 is rotatably connected between the two sets of connecting blocks 206. The connecting rod 207 is located below the positioning circular plate 205. A limiting block 208 is fixedly connected to the circumference of the connecting rod 207. The limiting block 208 is engaged with the positioning groove.

[0025] One end of the connecting rod 207 is fixedly connected to a connecting plate 209. The connecting plate 209 is located on one side of the connecting block 206. A rocker arm 210 is fixedly connected to one surface of the connecting plate 209. A positioning screw 211 is provided inside the rocker arm 210. One end of the positioning screw 211 is threadedly connected to the linkage block 201.

[0026] A mounting bracket 103 is fixedly connected to one side of the base 1. A servo motor 104 is installed inside the mounting bracket 103. A threaded rod is fixedly connected to the output end of the servo motor 104. The threaded rod is set in the slide groove 102 and rotates with the slide groove 102. A slider 204 is set on the periphery of the threaded rod and threadedly engages with the threaded rod.

[0027] The other end of the linkage rod 202 is fixedly connected to a rotating handle 212, which is located on one side of the positioning circular plate 205. By setting the rotating handle 212, it is convenient to rotate the linkage rod 202, thereby adjusting the direction of the clamped turbine blade and facilitating multi-faceted processing of the turbine blade.

[0028] It should be further explained that in actual use, the turbine blade to be processed is placed between two sets of contour chucks 203. The servo motor 104 drives the slider 204 to move within the slide groove 102 via a threaded rod, which in turn moves the linkage block 201. This allows the two sets of contour chucks 203 to clamp and fix the turbine blade. The contour chucks 203, linkage rod 202, and rotating rod are all threadedly connected, allowing for appropriate replacement according to the required turbine blade size for better clamping. After clamping and fixing, when multi-faceted machining and cutting of the turbine blade is required, the screw... The positioning screw 211 is moved to release the restriction between the positioning screw and the linkage block 201. Then, the connecting rod 207 is rotated through the swing rod 210 and the connecting plate 209, causing the limiting block 208 to separate from the positioning circular plate 205. Then, the linkage rod 202 is rotated by rotating the handle 212, thereby adjusting the direction of the clamped turbine blade. The limiting block 208 is then swung back to its original position, so that it is engaged with the positioning circular plate 205. The positioning screw 211 is used to reinforce the limiting performance of the limiting block 208 and ensure the stability of the clamping. This allows for multi-faceted processing and cutting of the turbine blade. The structure is simple and the operation is convenient.
