Description

Technical Field

[0001] This utility model relates to the field of diffuser tooling technology, specifically to tooling for ultrasonic testing of radial diffuser mechanical assembly. Background Technology

[0002] The radial diffuser mechanical assembly of a certain type of engine has five brazed joints on each of its front and back sides. During inspection of both sides, the positions of the brazed joints must be manually adjusted, wasting a significant amount of time. Furthermore, the inspection of the brazed joints of the radial diffuser mechanical assembly uses an ultrasonic immersion testing method, which involves continuous immersion in water, making it highly susceptible to corrosion. Therefore, a fixture for ultrasonic testing of this diffuser mechanical assembly was designed. By determining the position of the brazed joints within the equipment space, the time required for inspection personnel to place the parts is reduced, improving efficiency. Electrochemical corrosion protection also reduces the risk of corrosion. Utility Model Content

[0003] The purpose of this invention is to provide a tooling for ultrasonic testing of a radial diffuser mechanical assembly. By forming a workpiece mounting and positioning block on the annular base that corresponds to the screw seat position, the positioning efficiency is improved, and the testing time for a single workpiece is shortened by 20 minutes. At the same time, an anode metal is connected to the base, and the sacrificial anode metal is used to protect the workpiece and reduce corrosion.

[0004] This utility model provides the following technical solution: a tooling for ultrasonic testing of a radial diffuser mechanical combination, including a base with multiple mounting holes. Multiple workpiece clamping and positioning blocks are formed in the mounting holes, each corresponding to a screw seat of the diffuser. Clamping bolts are inserted into the mounting holes and used to connect with the screw seats, fixing the diffuser onto the workpiece clamping and positioning blocks. A test block placement support plate is also connected to the base, and a test block placement positioning plate is connected to the upper end of the support plate. Test blocks are placed on the positioning plate and located on the diffuser. An anode metal block is also connected to the base, located between adjacent workpiece clamping and positioning blocks. The electricity price of the anode metal block is higher than that of the workpiece material.

[0005] To reduce the likelihood of the mounting bolts loosening in water or under ultrasonic vibration conditions, and to enhance the connection strength and pressure between the mounting bolts and the bolt seat, the mounting hole includes a nut groove, a recessed groove, a bolt hole, and a circular groove. The diameter of the recessed groove is larger than the diameter of the bolt hole. A spring is installed inside the recessed groove, and the diameter of the spring is larger than the diameter of the bolt hole. The spring is sleeved on the mounting bolt and is located between the end face of the recessed groove and the end face of the nut.

[0006] To limit the movement of the mounting bolt and prevent it from falling off the base, the mounting bolt has a groove formed on it, and a retaining ring is engaged in the groove. The diameter of the retaining ring is larger than the diameter of the bolt hole.

[0007] In order to fine-tune the mounting bolt so that the mounting bolt and the screw seat on the diffuser correspond, a circular hole is opened on the surface of the workpiece mounting and positioning block, and a workpiece positioning ring is provided in the circular hole. The workpiece positioning ring is sleeved on the mounting bolt.

[0008] To position the base during installation, recessed positioning grooves are formed on both the inner and outer diameters of the base, and these positioning grooves cooperate with the equipment chuck.

[0009] In order to locate the installation position of the test block, a positioning hole is provided on the test block placement positioning plate, and the test block is placed in the positioning hole.

[0010] The anode metal block is a zinc block.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] (1) By forming a workpiece mounting and positioning block on the annular base that corresponds to the screw seat position, the positioning efficiency is improved, and the inspection time of a single workpiece is shortened by 20 minutes.

[0013] (2) An anode metal is connected to the base. The valence of the anode metal is greater than that of the workpiece, so that the anode metal will corrode first in the water, thereby sacrificing the anode metal to protect the workpiece and reduce the corrosion of the workpiece.

[0014] (3) By attaching a spring to the mounting bolt, the spring is compressed when the mounting bolt and the screw seat are connected, which increases the tension between the mounting bolt and the screw seat, locks the mounting bolt and the screw seat, reduces the possibility of the mounting bolt loosening under the vibration of water and ultrasound, ensures the workpiece position requirements, and further ensures the accuracy of the detection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a tooling for ultrasonic testing of a radial diffuser mechanical assembly, including a base 1. The base 1 has multiple mounting holes 12, and multiple workpiece clamping and positioning blocks 2 are formed on the mounting holes 12. The workpiece clamping and positioning blocks 2 correspond to the screw seat positions of the diffuser, used for mounting and positioning the diffuser, improving the installation efficiency. Clamping bolts 7 are inserted into the mounting holes 12, used to connect with the screw seat, fixing the diffuser to the workpiece clamping and positioning blocks 2. By rotating the clamping bolts 7, the screw seat is fixed to the workpiece clamping and positioning blocks 2, improving positioning efficiency and reducing the single-piece testing time by 20 minutes. A test block placement device is also connected to the base 1. The support plate 3 is connected to a test block placement positioning plate 4 at its upper end. The test block is placed on the test block placement positioning plate 4 and is located on the diffuser. An anode metal block 5 is also connected to the base 1. The anode metal block 5 is located between adjacent workpiece clamping positioning blocks 2. The anode metal block 5 has a higher charge than the workpiece material. The anode metal block 5 is a zinc block. During testing, the entire fixture is placed in water. By placing the anode metal block 5, which has a higher charge, the anode metal block 5 will react before the base 1 and other fixtures and workpieces. The sacrificial anode metal block 5 is used to protect the fixture and reduce corrosion of the fixture and workpiece.

[0023] like Figure 3 and 4As shown, the mounting hole 12 includes a nut groove 121, a recessed groove 122, bolt holes 123 and 123, and a circular groove. The diameter of the recessed groove 122 is larger than the diameter of the bolt holes 123 and 123. A spring 8 is installed inside the recessed groove 122. The diameter of the spring 8 is larger than the diameter of the bolt holes 123. The spring 8 is sleeved on the clamping bolt 7. The spring 8 is located between the end face of the recessed groove 122 and the end face of the nut. Through the connection between the clamping bolt 7 and the screw seat, the spring is compressed, which enhances the tension between the clamping bolt 7 and the screw seat, locks the clamping bolt 7 and the screw seat, reduces the impact of water vibration on the clamping bolt 7, prevents the clamping bolt 7 from loosening in the water, ensures the positioning of the workpiece, and improves the accuracy of the detection.

[0024] The mounting bolt 7 has a groove formed on it, and a retaining ring 71 is engaged in the groove. The diameter of the retaining ring 71 is larger than the diameter of the bolt hole 123. The retaining ring 71 is used to limit the mounting bolt 7 and prevent the mounting bolt 7 from falling off the bottom of the base 1.

[0025] A circular hole is provided on the surface of the workpiece mounting and positioning block 2, and a workpiece positioning ring 6 is provided in the circular hole. The workpiece positioning ring 6 is sleeved on the mounting bolt 7. The workpiece positioning ring 6 further positions and fine-tunes the mounting bolt 7. The surface of the workpiece positioning ring 6 is lower than the surface of the workpiece mounting and positioning block 2, which makes it convenient to embed the bottom surface of the screw seat into the workpiece mounting and positioning block 2. Through the fine-tuning of the mounting bolt 7, each mounting bolt 7 can be connected to the corresponding screw seat.

[0026] The base 1 has recessed positioning grooves 11 formed on both its inner and outer diameters. The positioning grooves 11 cooperate with the equipment chuck to position the base 1 in the installation position.

[0027] like Figure 2 As shown, the test block placement and positioning plate 4 has positioning holes 41. The test block is placed in the positioning holes 41. Through the setting of the test block, it is determined that the test block is an artificial reflector with a simple geometric shape designed for a specific purpose. They are usually used in ultrasonic flaw detection as a standard reference to help calibrate and adjust flaw detection equipment and parameters, ensuring the accuracy of the detection.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
