Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to aviation engine parts detection frock technical field, concretely relates to a kind of limit detection measuring tool for aviation anti-icing solenoid valve support. BACKGROUND
[0002] Anti-icing solenoid valve support is widely used in aviation engine parts, which is arc-shaped, and the arc requirement is strict. The processing quality of anti-icing solenoid valve support directly affects the quality of aircraft engine to some extent. However, when detecting the arc of anti-icing solenoid valve support by using the traditional detection method, it is not only time-consuming and laborious, but also difficult to ensure the accuracy of the measured size due to the elastic force characteristics of anti-icing solenoid valve support, which is prone to measurement error. UTILITY MODEL CONTENT
[0003] The utility model aims at providing a limit detection measuring tool for aviation anti-icing solenoid valve support parts, which has a reasonable structure and is reliable in use, can significantly improve the measurement efficiency and accuracy, reduce the measurement cost, and has strong practicality and operability.
[0004] The technical scheme of the utility model is as follows:
[0005] A limit detection measuring tool for aviation anti-icing solenoid valve support, which comprises a bottom plate, a pressing block, a detection gauge and a handle. An arc-shaped boss is arranged in the middle of the upper surface of the bottom plate. A groove with the same arc as the arc-shaped boss is arranged on the lower surface of the pressing block. A clamping space corresponding to the aviation anti-icing solenoid valve support is formed between the arc-shaped boss and the groove. Lower longitudinal column pin holes are arranged on both sides of the arc-shaped boss of the bottom plate. Upper longitudinal column pin holes corresponding to the lower longitudinal column pin holes are arranged on the pressing block. The detection gauge comprises two column pins corresponding to the upper longitudinal column pin holes. The handle has two ends connected with the upper ends of the two column pins.
[0006] The lower longitudinal column pin hole is a stepped hole, and the upper longitudinal column pin hole is a circular through hole concentric with the corresponding lower longitudinal column pin hole.
[0007] The lower part of the column pin matches the shape and size of the lower longitudinal column pin hole, and the upper part of the column pin matches the shape and size of the upper longitudinal column pin hole.
[0008] The upper end of the column pin is provided with a radial through hole, and the handle is rod-shaped and inserted into the radial through hole.
[0009] The utility model has the advantages of reasonable structure, reliable use, high measurement efficiency and accuracy, low measurement cost, strong practicality and operability.
[0010] In use, the aviation anti-icing solenoid valve bracket is held in place by the arched boss on the base plate and the groove in the pressure block. The arched boss and groove match the curvature of the anti-icing solenoid valve bracket, preventing deformation. Then, the two pins of the inspection gauge are inserted into the corresponding upper longitudinal pin holes. If the lower end of the pin can be easily inserted into the lower longitudinal pin hole, the curvature of the anti-icing solenoid valve bracket is acceptable. If it cannot be easily inserted, the curvature is unacceptable. This measurement structure is simple and easy to operate, reduces measurement costs, and is highly practical and operable. Simultaneously, it significantly improves measurement efficiency and accuracy. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the structure of this utility model.
[0012] In the diagram: 1. Handle, 2. Inspection gauge, 3. Pressure block, 301. Groove, 4. Base plate, 401. Arched boss. Detailed Implementation
[0013] The present invention will be described in detail with reference to the accompanying drawings.
[0014] like Figure 1 As shown, the limit detection gauge for the support of the anti-icing solenoid valve in aviation consists of a base plate 4, a pressure block 3, a gauge 2, and a handle 1.
[0015] The base plate 4 has an arched boss 401 in the middle of its upper surface, and the pressure block 3 has a groove 301 on its lower surface that has the same curvature as the arched boss 401. The arched boss 401 and the groove 301 form a clamping space for the corresponding aviation anti-icing solenoid valve bracket.
[0016] The base plate 4 has lower longitudinal pin holes on both sides of the arched boss 401. The pressure block 3 has upper longitudinal pin holes that correspond one-to-one with the lower longitudinal pin holes. The inspection gauge 2 consists of two pins that correspond one-to-one with the upper longitudinal pin holes. There are two handles 1, which are respectively connected and fixed to the upper ends of the two pins.
[0017] In this embodiment, the lower longitudinal pin hole is a stepped hole, and the upper longitudinal pin hole is a circular through hole concentric with the corresponding lower longitudinal pin hole. The lower part of the pin matches the shape and size of the lower longitudinal pin hole, and the upper part of the pin matches the shape and size of the upper longitudinal pin hole. The upper end of the pin is provided with a radial through hole, and the handle 1 is rod-shaped and inserted into the radial through hole.
[0018] Measurement tool method:
[0019] The aviation anti-icing solenoid valve bracket is placed between the arched boss 401 of the base plate 4 and the groove 301 of the pressure block 3. The curvature of the aviation anti-icing solenoid valve bracket is consistent with the curvature of the arched boss 401 and the groove 301, so it will not cause the aviation anti-icing solenoid valve bracket to deform. At the same time, it achieves the limitation of the aviation anti-icing solenoid valve bracket, avoids deformation during the measurement process, and improves the measurement accuracy.
[0020] Insert the two handles 1 into the radial through holes of the two pins of the inspection gauge 2, and then insert the two pins into the corresponding upper longitudinal pin holes respectively. If the lower end of the pin can be smoothly inserted into the lower longitudinal pin hole, it means that the curvature of the anti-icing solenoid valve bracket is qualified. If it cannot be smoothly inserted into the lower longitudinal pin hole, it means that the curvature of the anti-icing solenoid valve bracket is unqualified.
[0021] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
