A fixture for testing the bonding of curved surfaces of titanium alloy irregular parts

Abstract

This utility model discloses a fixture for inspecting the curved surface bonding of titanium alloy irregular parts, including an operating table with a circular hole on its surface. A sealed box is fixedly installed at the bottom of the operating table, and a connecting pipe is fixedly connected to the outside of the sealed box. The other end of the connecting pipe is fixedly connected to a vacuum pump. This utility model places the irregular part on the surface of a support plate, then covers the surface of the irregular part with a black film. By activating the vacuum pump, a vacuum is evacuated from the sealed box, allowing the black film to adhere tightly to the outside of the irregular part. During this process, a servo motor drives a screw to rotate, causing a moving sleeve to move a vertical rod to a specific position. This allows a heating element to heat the black film, further adhering it to the outside of the irregular part. Thus, any depressions or protrusions on the irregular part can be directly exposed to the outside, allowing for more intuitive detection.

Description

Technical Field

[0001] This utility model relates to the field of inspection technology for titanium alloy workpieces, specifically a tooling for inspecting the curved surface fit of irregularly shaped titanium alloy parts. Background Technology

[0002] Titanium alloys refer to various alloy metals made of titanium and other metals. They are structural metals with high strength, good corrosion resistance, and high heat resistance. They are mainly used to manufacture compressor parts for aircraft engines, and secondly for structural components of rockets, missiles, and high-speed aircraft.

[0003] After titanium alloy materials are processed and formed, there will be irregularly shaped parts of different shapes. Therefore, it is necessary to inspect the curved surfaces of the irregularly shaped parts to prevent the appearance of depressions or protrusions, which would affect the normal use of the irregularly shaped parts. However, currently, the irregularly shaped parts are usually inspected by hand. Due to the lack of auxiliary inspection fixtures, the inspection efficiency of personnel is low. To address this issue, we propose a titanium alloy irregularly shaped part curved surface fitting inspection fixture to solve the above problems. Utility Model Content

[0012] This utility model provides a tooling for testing the curved surface fit of titanium alloy irregular parts, which has the following advantages:

[0013] This invention places an irregularly shaped part on the surface of a support plate, then covers the surface of the part with a black film. By activating a vacuum pump, the inside of the sealed box is evacuated, allowing the black film to adhere tightly to the outside of the part.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3As shown in this embodiment, a titanium alloy irregular-shaped part curved surface bonding inspection fixture includes an operating table 1. A circular hole 2 is formed on the surface of the operating table 1. A sealing box 3 is fixedly installed at the bottom of the operating table 1. A connecting pipe 4 is fixedly connected to the outside of the sealing box 3. The other end of the connecting pipe 4 is fixedly connected to a vacuum pump 5. The vacuum pump 5 is fixedly installed on a base plate 6. The base plate 6 is fixedly installed on the outside of a support rod on the operating table 1. A support plate 7 is placed on the surface of the operating table 1. A black film 8 is placed above the support plate 7. The surface of the operating table 1 abuts against a vertical... A heating element 10 is provided on the outer side of the pole 9. A movable sleeve 11 is fixedly installed at the bottom end of the pole 9. The movable sleeve 11 is inserted into the inside of the limiting groove 12, which is opened on the surface of the operating table 1. A screw 13 is engaged with the inside of the movable sleeve 11. The other end of the screw 13 is fixedly connected to the end of the shaft of the servo motor 14. The servo motor 14 is fixedly installed on the outer side of the operating table 1. The irregular part is placed on the surface of the support plate 7, and then a black film 8 is covered on the surface of the irregular part. With the start of the vacuum pump 5, the sealing box 3 can be heated. Internal vacuum extraction is performed to ensure the black film 8 adheres tightly to the outer side of the irregularly shaped part. During this process, the servo motor 14 drives the screw 13 to rotate, causing the moving sleeve 11 to move the upright 9 to a specific position. This allows the heating element 10 to heat the black film 8, further adhering it to the outer side of the irregularly shaped part. Consequently, any depressions or protrusions on the irregularly shaped part are directly exposed to the outside, allowing for more direct detection by personnel. The circular holes 2 are evenly distributed on the surface of the operating table 1. The support plate 7 is made of plastic material. The circular hole 2 is connected to the sealing box 3. As the irregular part is placed on the surface of the support plate 7, the black film 8 is subsequently covered on the irregular part. The outer side of the movable sleeve 11 abuts against the inner wall of the limiting groove 12. The movable sleeve 11 can slide inside the limiting groove 12, so that the movable sleeve 11 can drive the movement of the upright 9. The screw 13 is rotatably connected to the inside of the limiting groove 12. The screw 13 and the movable sleeve 11 are engaged by a fine thread. The movable sleeve 11 can stably move on the outside of the screw 13.

[0022] like Figure 2 and Figure 4As shown, the heating element 10 includes a horizontal plate 15, a heating plate 16 fixedly disposed at the bottom of the horizontal plate 15, and a square sleeve 17 fixedly installed on the outer side of the horizontal plate 15. The square sleeve 17 is sleeved on the outer side of the upright 9, and a bolt 18 is engaged with the square sleeve 17. One end of the bolt 18 is tightly attached to the outer side of the upright 9. Through the square sleeve 17 disposed on the outer side of the horizontal plate 15, the square sleeve 17 can slide on the outer side of the upright 9, so that the horizontal plate 15 can drive the heating plate 16 to perform height adjustment. This allows for movement according to irregularly shaped parts of different heights. The inner wall of the square sleeve 17 abuts against the outer side of the upright 9. The outer edge of the upright 9 is set in an arc shape to facilitate the pushing operation of the square sleeve 17 by personnel. The outer side of the bolt 18 is provided with anti-slip texture, which is evenly distributed on the outer side of the bolt 18 to facilitate the rotation operation of the bolt 18 by personnel.

[0023] This utility model provides a fixture for inspecting the curved surface fit of titanium alloy irregular parts. The specific working principle is as follows:

[0024] In use, the operator places the support plate 7 on the surface of the operating table 1, then places the irregular part on the surface of the support plate 7, and then covers the surface of the irregular part with a black film 8. With the start of the vacuum pump 5, the inside of the sealed box 3 is evacuated, so that the black film 8 can adhere tightly to the outside of the irregular part. During this period, the servo motor 14 drives the screw 13 to rotate, so that the moving sleeve 11 can move the upright 9 to a position. Thus, the heating element 10 can heat the black film 8, so that the black film 8 can adhere even more tightly to the outside of the irregular part. Thus, any depressions or protrusions on the irregular part can be directly exposed to the outside, allowing the operator to detect them more intuitively. When the height of the heating plate 16 needs to be adjusted, the operator pushes the square sleeve 17 upward, so that the horizontal plate 15 can move the heating plate 16. Then, the bolt 18 is rotated on the square sleeve 17, and one end of the bolt 18 can adhere tightly to the outside of the upright 9. Thus, the heating element 10 can heat irregular parts at different heights.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
