Technical Field

[0001] The utility model relates to the technical field of aerospace component processing, in particular to a component precision measuring device. Background Art

[0002] Aerospace components typically require extremely high precision because they operate in extreme environments, and any slight error can lead to serious consequences. Precise measurement allows for real-time monitoring of deviations during the manufacturing process, allowing for timely adjustment of process parameters to ensure that the quality of each component meets the requirements of the design drawings and technical specifications. This is particularly important in mass production, as the failure of any single component can lead to failure of the entire system.

[0003] In the manufacturing process of aerospace parts, accurate dimensional measurement is crucial. Traditional measurement methods usually rely on a variety of different measuring tools, such as vernier calipers, micrometers, depth gauges, etc. Each tool corresponds to a different measurement task. This method is not only time-consuming, but also prone to human errors during the frequent tool changes, reducing measurement accuracy and efficiency.

[0004] Furthermore, for complex parts, such as those with holes, multiple parameters such as height, length, width, and hole depth need to be measured. Using traditional tools for these multi-step measurements is not only cumbersome but also difficult to ensure consistency and accuracy between measurement steps. Hole depth measurement, in particular, typically requires specialized depth measurement tools, which increases operational complexity and costs. Utility Model Content

[0030] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0031] Please refer to Figures 1-8 An embodiment of the utility model provides a component precision measuring device, including a measuring platform 1, a measuring component 1 is installed on one side of the measuring platform 1, and the measuring component 1 is used to measure the height of aerospace components.

[0032] Among them, the measuring component 1 includes a height measuring plate 2 perpendicular to the measuring platform 1, a measuring ruler 4 is provided on one side of the height measuring plate 2, an adjusting block 5 is slidably connected to the height measuring plate 2, and a measuring rod 6 is provided on one side of the adjusting block 5. The adjusting block 5 slides on the height measuring plate 2 so that the measuring rod 6 contacts the upper end of the part. The position of the measuring rod 6 on the measuring ruler 4 is read to obtain the height of the part.

[0033] Furthermore, an adjusting screw 3 is rotatably provided on the measuring table 1, the adjusting screw 3 passes through the adjusting block 5 and is threadedly connected to the adjusting block 5. The adjusting screw 3 is driven by a motor. When the adjusting screw 3 rotates, the adjusting block 5 automatically slides up and down, thereby realizing automatic measurement of the part height.

[0034] In addition, a rotating block 7 is movably connected to one end of the measuring rod 6, a long rod 8 is provided at the lower end of the rotating block 7, and a measuring head 9 is provided at the lower end of the long rod 8. The measuring head 9 has a scale. The measuring head 9 is used to measure the depth of the hole on the part. The position of the measuring head 9 is adjusted by rotating the rotating block 7 so that the measuring head 9 does not affect the use of the measuring rod 6.

[0035] In order to improve the measurement accuracy, a marking sleeve 10 is slidably connected to the measuring head 9. The marking sleeve 10 is connected to the long rod 8 through a spring 12. The marking sleeve 10 is pushed upward when the measuring head 9 enters the hole. The elastic contraction of the spring 12 makes the marking sleeve 10 always located at the upper end of the hole to mark the depth of the hole. Bumps 11 are provided on both sides of the lower end of the marking sleeve 10 to prevent the marking sleeve 10 from entering the hole.

[0036] A slide rail 13 is provided on the measuring table 1 on one side of the measuring component. The two ends of the slide rail 13 are slidably connected to the measuring component 2. The measuring component 2 measures the part through relative movement. The measuring component 1 and the measuring component 2 do not interfere with each other.

[0037] Specifically, the measuring component 2 includes a movable plate 15 and a movable plate 2 19 that are slidingly connected to the slide rail 13. A bidirectional screw rod 14 is rotatably arranged in the slide rail 13. The bidirectional screw rod 14 is threadedly connected to the movable plate 15 and the movable plate 2 19 respectively. The bidirectional screw rod 14 is driven by a motor. When the bidirectional screw rod 14 rotates, it causes the movable plate 15 and the movable plate 2 19 to approach each other and fit with the two sides of the part respectively.

[0038] It is worth noting that a mounting groove 17 is provided at the upper end of the movable plate 15, and a measuring ruler 2 16 is slidably connected in the mounting groove 17. The measuring ruler 2 16 in the mounting groove 17 is fixed by a positioning pin 18, so that the measuring ruler 2 16 is easy to disassemble and assemble, and a slide groove 20 is provided at the upper end of the movable plate 2 19 to be slidably connected to the measuring ruler 2 16, and a marking rod 21 is provided at the upper end of the slide groove 20. When the movable plate 15 and the movable plate 2 19 approach each other, the measuring ruler 2 16 enters the slide groove 20, and the reading is obtained by the position pointed by the marking rod 21 on the measuring ruler 2 16 to complete the measurement of the length or width of the part.

[0039] In summary, the working principle of a component precision measuring device in an embodiment of the present invention is as follows: by sliding the adjustment block 5 on the height measuring plate 2, the measuring rod 6 is brought into contact with the upper end of the component, and the position on the ruler 1 4 is measured by the measuring rod 6 to obtain the height of the component, and at the same time, the movable plate 15 and the movable plate 2 19 are brought close to each other. When the measuring ruler 2 16 enters the slide groove 20, the length or width of the component is obtained by pointing the marking rod 21 on the measuring ruler 2 16. By adjusting the rotation of the screw rod 3, the adjustment block 5 is lowered, so that the measuring head 9 enters the hole of the component, and the measuring head 9 is used to measure the depth of the hole of the component.

[0040] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
