Problems solved by technology

[0004] In the blade processing, the geometric size of the blade is mainly controlled, so as to indirectly ensure the static frequency. A steam turbine has many blades, and the profile lines of the blades at each level are generally different. The processing fixtures and fixtures are set separately, that is to say, multiple fixtures are required to process different parts of the blade, and the clamping force used for different sizes of blades is different. The size of the holding force is judged based on experience, which will cause some blades to be deformed due to the excessive clamping force of the fixture, or the surface will be damaged, so they cannot be used on steam turbines. It is very inconvenient to install or disassemble the processing fixture tool, the traditional fixture is very inconvenient to adjust, increases labor intensity, and the production efficiency is low. Therefore, the present invention proposes a horizontal fixture for steam turbine blade processing with adjustable strength to solve the above technical problems

Embodiment 1

[0033] see Figure 1-6, this embodiment provides a horizontal jig for processing steam turbine blades with adjustable strength, including a mounting frame 1, one end of the mounting frame 1 is fixedly connected with a mounting plate 10, and the other end of the mounting frame 1 is fixedly connected with a fixing plate 4, which is fixed The plate 4 is fixedly connected with the mounting frame 1 by screws, so as to facilitate the maintenance and replacement of the sliding clamps in the mounting frame 1. A sliding block 2 is slidably installed in the middle of the mounting frame 1, and the sliding block 2 is close to the side of the fixed plate 4 The movable plate 3 is fixedly connected. By setting the movable plate 3 and the fixed plate 4, the steam turbine blades can be fixedly clamped. The inside of the sliding block 2 is rotatably installed with a lead screw 6, and one end of the lead screw 6 is rotatably connected to the fixed plate 4. , the other end of the screw rod 6 pene...

Embodiment 2

[0039] see Figure 1-10 , made further improvements on the basis of Example 1:

[0040] When the blade is integrally processed, it needs to be installed or removed on different processing fixtures many times. When adjusting the distance between the fixture heads, the existing fixture needs to rotate the adjusting rod at the tail, which makes the adjustment very inconvenient and cannot be quickly adjusted. The position of the fixture head is positioned according to the needs, which will affect the processing efficiency. In order to solve this problem, please refer to Figure 7 , a position adjusting device 8 is arranged in the inner cavity of the sliding block 2, please refer to Figure 8 , the position adjustment device 8 includes an upper clamping block 84 and a lower clamping block 86. By setting the upper clamping block 84 and the lower clamping block 86, the upper and lower clamping blocks can be separated during adjustment, and then the clamp head can be separated from t...

Embodiment 3

[0044] see Figure 1-13 , made further improvements on the basis of Example 2:

[0045] Most of the fixture heads of the existing clamping devices are made of hard materials. When clamping a curved workpiece, it is easy to cause deformation of the workpiece or damage to the workpiece. In order to prevent the clamp from causing damage to the steam turbine blade clamping, please refer to figure 1 , the opposite side of the moving plate 3 and the fixed plate 4 is provided with a connecting groove 5. By setting the connecting groove 5, the clamping head protection device can be adjusted according to different clamping workpieces, which effectively improves the use range of the fixture. Please see figure 1 and 11 , the movable plate 3 and the fixed plate 4 are movably installed with the flexible clamping device 9 through the connection slot 5 and the connection block 51, please refer to Figure 12-13 The flexible clamping device 9 includes an ejector pin storage box 91, a number...

Abstract

The invention discloses a strength-adjustable horizontal fixture for machining turbine blades, and relates to the technical field of fixtures. The strength-adjustable horizontal fixture comprises a mounting frame, a mounting plate is fixedly connected to one end of the mounting frame, a fixing plate is fixedly connected to the other end of the mounting frame, and a sliding block is slidably mounted in the middle of the mounting frame; the side, close to the fixing plate, of the sliding block is fixedly connected with a moving plate, a lead screw is rotationally installed in the sliding block, one end of the lead screw is rotationally connected with the fixing plate, and the other end of the lead screw penetrates through the mounting plate and is fixedly connected with a clamping force adjusting device. The clamping force of the clamp can be adjusted according to different blade clamping requirements, the steam turbine blade is effectively protected, the distance between the clamp and the blade can be rapidly adjusted by arranging the position adjusting device, and therefore the blade can be rapidly clamped or loosened.

Description

technical field [0001] The invention relates to the related technical field of clamps, in particular to a horizontal clamp for processing steam turbine blades with adjustable strength. Background technique [0002] A steam turbine, also known as a steam turbine engine, is a rotary steam power device. The high-temperature and high-pressure steam passes through a fixed nozzle to become an accelerated airflow and then sprays it onto the blades, so that the rotor equipped with the blade row rotates and does external work at the same time. A steam turbine is an external combustion rotary machine that can convert steam heat energy into mechanical work. After the steam from the boiler enters the steam turbine, it sequentially passes through a series of annularly arranged nozzles and moving blades to convert the thermal energy of the steam into the mechanical energy of the steam turbine rotor rotation. Steam is converted into energy in different ways in a steam turbine, which const...
