Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aviation clamp calibration tools, and in particular to calibration molds for aviation clamps. Background Technology
[0002] In the aviation industry, aviation clamps, as a key connecting and fastening component, are widely used for connecting and fixing various pipelines in aircraft fuel systems, hydraulic systems, pneumatic systems, etc. The stability and reliability of their performance are directly related to the overall safe operation of aviation equipment. Once the clamp has problems such as dimensional deviation or loose connection, it may cause serious failures such as fuel leakage and abnormal pressure, and even endanger flight safety. With the continuous development of the aviation industry, the precision requirements for aviation clamps are increasing. Aviation clamps usually need to have extremely high dimensional accuracy and structural consistency to ensure that they can maintain stable connection performance for a long time in complex aviation environments (such as high temperature, high pressure, vibration, etc.). Therefore, the calibration process is crucial in the production and manufacturing process of aviation clamps. It is a key process to ensure the dimensional accuracy and assembly performance of the clamps.
[0003] Currently, there are many types of calibration molds for aviation clamps on the market, but some shortcomings still exist in practical applications. Some calibration molds have limited calibration accuracy. During the stamping calibration of clamps, problems such as unstable guidance and improper pressure control can easily lead to dimensional deviations in the calibrated clamps, affecting the assembly quality of the clamps. Furthermore, they cannot calibrate unqualified clamps. In addition, the core calibration components (such as calibration rings) in existing calibration molds often use a fixed connection method. When it is necessary to replace calibration components according to different calibration requirements, the disassembly and assembly process is cumbersome and time-consuming, which seriously affects production efficiency and makes it difficult to meet the high-efficiency and precise production needs of modern aviation manufacturing. Therefore, it is necessary to improve these issues. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Example: See Figure 1-5The calibration mold for aviation clamps in this utility model includes a base 1 and a top plate 2 located on the upper end of the base 1. The base 1 facilitates the installation of the calibration mold 3, the first motor 9, and the second motor 11. A support column is installed between the base 1 and the top plate 2, and two symmetrical calibration molds 3 are installed on the top surface of the base 1, which facilitates the placement of the clamp. The calibration mold 3 has a calibration ring 4 inside, which facilitates the calibration of the clamp's curvature in conjunction with the calibration mold 3. A disassembly and assembly mechanism is installed at the lower end of the calibration ring 4, and a stamping mechanism is installed at the lower end of the top plate 2. The stamping mechanism includes a cylinder 5 installed at the center of the bottom surface of the top plate 2, which facilitates the descent of the stamping mold 6. The stamping mold 6 is installed at the telescopic end of the cylinder 5, which facilitates the stamping of irregularities on the inner surface of the clamp. An mounting plate 7 is installed around the stamping mold 6, which facilitates the installation of guide rods 8. Four guide rods 8 are fixedly connected to the four ends of the top surface of the mounting plate 7, which facilitates the descent of the stamping mold 6. The guide rod 8 facilitates the stamping of the stamping die 6; multiple guide rods 8 are sleeved with a first spring on their outer side, which helps to buffer the stamping process and prevent the stamping die 6 from damaging the clamps; the other end of the guide rod 8 passes through the top plate 2, the bottom end of the first spring is connected to the top surface of the mounting plate 7, and the top end of the first spring is connected to the bottom surface of the top plate 2. A first motor 9 is installed on one side of the base 1, which facilitates the rotation of the first bidirectional lead screw 10; the output end of the first motor 9 is connected to the first bidirectional lead screw 10 through a coupling, which facilitates the movement of the calibration die 3; one side of the bottom end of the calibration die 3 is threadedly connected to the first bidirectional lead screw 10, and the top surface of the base 1 is provided with a first sliding groove to cooperate with the movement of the calibration die 3. A second motor 11 is installed at the center of the other side of the base 1, which facilitates the rotation of the second bidirectional lead screw 12; the output end of the second motor 11 is connected to the second bidirectional lead screw 12 through a coupling, which facilitates the movement of the moving plate 13.
[0022] In this utility model, the disassembly and assembly mechanism includes a movable plate 13 inserted into the lower end of the calibration ring 4, which facilitates the movement of the calibration ring 4. The movable plate 13 is threadedly connected to the second bidirectional lead screw 12. Two reinforcing rods 14 are fixedly connected to the top of the movable plate 13, which helps to prevent the movable plate 13 and the calibration ring 4 from breaking during calibration. The reinforcing rods 14 are inserted into the calibration ring 4, and corresponding limiting grooves are provided at the lower end of the calibration ring 4 and the upper end of the movable plate 13. Limiting rods 16 are inserted into the limiting grooves, and baffles are fixedly connected to the middle of the limiting rods 16. Limiting plates 15 are fixedly connected to both sides of the upper end of the movable plate 13, which helps to prevent the movable plate 13 and the calibration ring 4 from separating. The other end of the limiting rod 16 passes through the limiting plate 15, and a second spring is sleeved on the outside of the limiting rod 16. One end of the second spring is connected to the baffle, and the other end of the second spring is connected to the inner side of the limiting plate 15.
[0023] Working principle: When using this invention, firstly, the aviation clamp to be calibrated is placed between two symmetrical calibration molds 3. The first motor 9 is started, and the output end of the first motor 9 drives the first bidirectional lead screw 10 to rotate through a coupling. Since one side of the bottom end of the calibration mold 3 is threadedly connected to the first bidirectional lead screw 10, and the top surface of the base 1 has a first sliding groove that cooperates with the movement of the calibration mold 3, under the rotation of the first bidirectional lead screw 10, the two calibration molds 3 will move in relative or opposite directions along the first sliding groove until the clamp is clamped. After initial positioning and securing of the clamp, cylinder 5 is activated. The telescopic end of cylinder 5 moves the stamping die 6 downwards. During this descent, the mounting plate 7 moves downwards simultaneously, and the guide rod 8 slides along the top plate 2, providing good guidance and ensuring accurate stamping calibration of the clamp by the stamping die 6. Simultaneously, the first spring is compressed as the mounting plate 7 moves downwards, providing cushioning and shock absorption during stamping, preventing damage to the clamp from excessive impact and improving the stability and accuracy of the calibration. When further... When replacing the calibration ring 4, the second motor 11 is started. The output end of the second motor 11 drives the second bidirectional lead screw 12 to rotate through the coupling. Since the moving plate 13 is threadedly connected to the second bidirectional lead screw 12, the moving plate 13 will move under the rotation of the second bidirectional lead screw 12. During the movement of the moving plate 13, the reinforcing rod 14 fixed at its top end will be pulled out from the calibration ring 4, releasing the reinforcement of the calibration ring 4. Subsequently, the limiting rod 16 is pulled outward, and the limiting rod 16 will move out of the corresponding limiting groove at the lower end of the calibration ring 4 and the upper end of the moving plate 13. Pull out the spring. At this time, the second spring is compressed. After the limit rod 16 is pulled out, the calibration ring 4 can be removed from the moving plate 13, completing the disassembly of the calibration ring 4. When installing the new calibration ring 4, place the new calibration ring 4 on the moving plate 13 so that the reinforcing rod 14 is inserted into the calibration ring 4. Then, release the limit rod 16. Under the elastic force of the second spring, the limit rod 16 will be re-inserted into the corresponding limit groove at the lower end of the calibration ring 4 and the upper end of the moving plate 13, realizing a stable connection between the calibration ring 4 and the moving plate 13, and completing the installation of the calibration ring 4.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
