Description

Technical Field

[0001] The utility model relates to the technical field of jigs, and particularly relates to a stator blade jig. Background Art

[0002] Stator blades are important components of an engine, used for rectifying and diffusing the airflow compressed by the moving blades. The angle of the stator blades can be adjusted. If there are no stator blades between two groups of moving blades, problems such as air leakage and low efficiency will occur.

[0003] The stator blade has an irregular arc surface and is not easy to fix during processing. After the current stator blade jig holds the stator blade, the clamping position cannot be changed. Therefore, some parts of the jig will block the stator blade, bringing inconvenience to processing. Summary of the Utility Model

Detailed Embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] In this application, unless otherwise clearly specified and defined, the terms "connection" and "fixation" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0023] In the description of this application, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "horizontal", "top", "bottom", "upper", "lower", "inner" and "outer" etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to this utility model.

[0024] In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. In the description of this utility model, the meaning of "a plurality" is more than two, unless otherwise clearly and specifically defined.

[0025] As Figures 1 - 4 shown, this utility model provides a stator blade fixture, which includes a base 10 and an arc-shaped bracket 20, and also includes a support plate 30, a clamping assembly 40 and a pressing assembly 50.

[0026] The support plate 30 is fixedly installed on the arc-shaped bracket 20 along the transverse direction and is used to support the bottom of the stator blade 60.

[0027] The number of the clamping assemblies 40 is two. The two clamping assemblies 40 are both arranged above the support plate 30 and are respectively located on both sides of the support plate 30. The two clamping assemblies 40 are respectively used to clamp both ends of the stator blade 60.

[0028] The pressing assembly 50 is arranged above the support plate 30, and the pressing assembly 50 is used to press the top of the stator blade 60.

[0029] When this fixture is in use, the stator blade 60 can be clamped from the upper and lower directions by the cooperation of the pressing assembly 50 and the support plate 30, so as to facilitate the processing equipment to process the upper end face of the stator blade 60. It can also clamp the stator blade 60 from the left and right directions by the two clamping assemblies 40, so as to facilitate the processing equipment to process other parts of the stator blade 60.

[0030] The pressing assembly 50 and the two clamping assemblies 40 can successively clamp the stator blades 60 respectively, so the clamping positions can be changed as needed, so that there will be no parts blocking the stator blades 60 during subsequent processing, which is convenient for processing the stator blades 60.

[0031] In one embodiment, the clamping assembly 40 includes a fixed block 41, a slide bar 42, a movable block 43 and a lead screw 44. The fixed block 41 is fixedly installed on the support plate 30. The slide bar 42 passes through the fixed block 41 transversely and is slidably connected to the fixed block 41. The movable block 43 is fixedly installed on the inner end face of the slide bar 42, and a limiting groove 46 adapted to the end of the stator blade 60 is formed in the movable block 43. The lead screw 44 passes through the fixed block 41 transversely and is threadedly connected to the fixed block 41. The lead screw 44 is rotatably connected to the movable block 43 and is kept parallel to the slide bar 42.

[0032] When the clamping assembly 40 works, the staff first places the stator blade 60 on the support plate 30, and then controls the rotation of the lead screw 44. Under the action of the slide bar 42, the movable block 43 will gradually approach the stator blade 60 until the end of the stator blade 60 is inserted into the corresponding limiting groove 46.

[0033] In this way, the two clamping assemblies 40 can clamp the stator blade 60 from the left and right directions.

[0034] In one embodiment, the clamping assembly 40 further includes a handle 45, and the handle 45 is fixedly installed on the outer end face of the slide bar 42 to facilitate the staff to control the rotation of the lead screw 44.

[0035] In one embodiment, a guiding groove 21 is formed in the arc-shaped bracket 20, and the extending direction of the guiding groove 21 is the same as that of the blade groove 61 on the stator blade 60. [[ID=********]]

[0036] The pressing assembly 50 includes a guiding rod 51, a guiding block 52, a spring 53, a pressing plate 54 and a limiting block 55. The guiding rod 51 is arranged in the guiding groove 21 and is fixedly connected to the inner wall of the guiding groove 21. The guiding block 52 is arranged in the guiding groove 21 and is slidably connected to the guiding rod 51. The spring 53 is sleeved on the guiding rod 51. The first end of the spring 53 is fixedly connected to the inner wall of the guiding groove 21, and the second end of the spring 53 is fixedly connected to the guiding block 52. The spring 53 makes the guiding block 52 tend to move downward. The pressing plate 54 is fixedly installed on the guiding block 52. The limiting block 55 is fixedly installed on the pressing plate 54 and is adapted to the blade groove 61.

[0037] When the pressing assembly 50 works, the operator first pulls the pressing plate 54 upward. Then, the stator blade 60 is placed on the support plate 30. After releasing the pressing plate 54, under the action of the spring 53, the guiding block 52 and the pressing plate 54 will move downward until the limiting block 55 is inserted into the corresponding blade groove 61. In this way, the cooperation between the pressing assembly 50 and the support plate 30 clamps the stator blade 60 from the upper and lower directions, facilitating the processing equipment to process the upper end face of the stator blade 60.

[0038] In one embodiment, the pressing assembly 50 further includes an iron block 56 and an electromagnet 57. The iron block 56 is fixedly installed on the pressing plate 54. The electromagnet 57 is fixedly installed on the arc-shaped bracket 20 and is located above the iron block 56. The electromagnet 57 is electrically connected to an external controller.

[0039] In the initial state, the electromagnet 57 is in the energized state. At this time, the electromagnet 57 is adsorbed to the iron block 56, and the pressing plate 54 is far away from the stator blade 60.

[0040] When the pressing assembly 50 works, the operator can cut off the power supply of the electromagnet 57 through the external control cabinet. At this time, under the action of the spring 53, the guiding block 52 and the pressing plate 54 will move downward until the limiting block 55 is inserted into the corresponding blade groove 61.

[0041] In one embodiment, the number of the limiting blocks 55 is three, and the three limiting blocks 55 respectively match the three blade grooves 61.
