Description

Technical Field

[0001] This utility model belongs to the technical field of special equipment measuring tools, specifically a special measuring tool for special equipment. (Test fixture standard parts) Background Technology

[0002] In the manufacturing, assembly, and maintenance of special equipment (missiles), accurately measuring the relative protrusion of the ignition contact and the inner wall of the cylindrical tube, as well as verifying the installation position of the deflector lever, are crucial. The ignition contact is used to generate a large instantaneous current during ignition control. If the distance between its contact surface and the launcher is incorrect, it will affect the conduction of the large current, potentially leading to serious consequences such as barrel entrapment. The deflector lever is an effective device to prevent the launcher from slipping. If its distance (assembly) is incorrect, causing the launcher to slip, it will render the launcher unusable, creating safety hazards and equipment damage.

[0003] Existing measurement methods mainly rely on steel rulers, but this method has many problems: First, the measurement speed is slow and the efficiency is low, making it difficult to meet the needs of high-precision and fast-paced production; second, it is difficult to grasp the starting point scale line of a steel ruler, resulting in large measurement errors and making it impossible to guarantee the accuracy of the measurement results, which in turn affects the assembly quality and safety of special equipment.

[0009] Furthermore, the line width of both the first and second scale lines is 0.5 mm.

[0010] Furthermore, when the measuring body is used to measure the relative protrusion of the ignition contact at the end of the round tube and the inner wall of the round tube, the first step is in contact with the inner wall of the round tube.

[0011] Furthermore, when the measuring body is used to measure the length and height of the bullet-stop lever on the outer wall of the circular tube, the side of the measuring body facing the bullet-stop lever is in contact with the outer wall of the circular tube, and one end of the groove is aligned with the bullet-stop lever.

[0026] The following is combined Figures 1-5 This utility model will be described in detail.

[0027] Example

[0028] Example 1

[0029] Depend on Figure 1-5It is known that a special measuring tool for special equipment includes a measuring body 1. The measuring body 1 is made of high-strength, wear-resistant, and corrosion-resistant alloy steel material, and its surface is finely processed and polished to ensure the flatness and accuracy of the measuring surface.

[0030] The measuring body 1 has a three-step structure on the side facing the ignition contact 11, including a first step 2, a second step 3, and a third step 4 arranged sequentially from one end of the measuring body 1 to the other end. The distance between the first step 2, the second step 3, and the third step 4 and the ignition contact 11 decreases sequentially.

[0031] Specifically, the height difference between the first step 2 and the second step 3 is 1.5 mm, and the height difference between the second step 3 and the third step 4 is 0.5 mm.

[0032] Furthermore, by designing the side of the measuring body 1 facing the ignition contact 11 as an arc-shaped surface that fits against the inner wall of the circular tube 10, it is ensured that the measuring body 1 fits tightly against the inner wall of the circular tube 10. Additionally, the first step 2, the second step 3, and the third step 4 are arranged perpendicular to the ignition contact 11.

[0033] When the measuring body 1 is used to measure the relative protrusion of the ignition contact 11 at the port of the round tube 10 to the inner wall of the round tube 10, the first step 2 is first brought into contact with the inner wall of the round tube 10, and then the measuring body 1 is pushed to slide towards the inner wall of the round tube 10.

[0034] When the side of the second step 3 blocks the ignition contact 11, i.e. when the ignition contact 11 is in the first step 2, or when the side of the third step 4 blocks the ignition contact 11, i.e. when the ignition contact 11 is in the second step 3, the requirement that the ignition contact 11 extends into the wall of the round tube 10 by 1-2 mm is met.

[0035] When the ignition contact is in the third step 4, it does not meet the requirement that the ignition contact 11 extends into the wall of the round tube 10 by 1-2 mm.

[0036] Example 2

[0037] Depend on Figure 1-5 It is known that a special measuring tool for special equipment is used to verify whether the bullet-stop lever 12 on the outer wall of the round tube 10 is installed in place; the measuring body 1 has a groove 5 on the side facing the bullet-stop lever 12, and the depth of the groove 5 is 11 mm. One end of the groove 5 is a limiting surface 8, and the other end penetrates the measuring body 1 to form an opening 9.

[0038] The groove 5 is provided with a first scale line 6 and a second scale line 7. The distance between the first scale line 6 and the limiting surface 8 is 46 mm. The second scale line 7 is located on the side of the first scale line 6 near the opening 9. The distance between the first scale line 6 and the second scale line 7 is 0.5 mm.

[0039] Furthermore, the line width of both the first scale line 6 and the second scale line 7 is 0.5 mm.

[0040] Meanwhile, the side of the measuring body 1 facing the bullet-blocking lever 12 is designed as an arc-shaped surface that fits the outer wall of the round tube 10, ensuring that the measuring body 1 fits tightly against the outer wall of the round tube 10.

[0041] When the measuring body 1 is used to verify whether the spring-blocking lever 12 on the outer wall of the round tube 10 is installed in place, firstly, the side of the measuring body 1 facing the spring-blocking lever 12 is attached to the outer wall of the round tube 10, then the opening 9 at one end of the groove 5 is aligned with the spring-blocking lever 12, and then the measuring body 1 is pushed until the limiting surface 8 is attached to the spring-blocking lever 12.

[0042] At this point, observe whether the head of the bullet-blocking lever 12 exceeds the first scale line 6 but does not exceed the second scale line 7 to determine if its front-to-back distance meets the standard of 46-47 mm. If it exceeds the second scale line 7, adjustment is required.

[0043] Meanwhile, since the depth of the groove 5 is 11 mm, which matches the depth of the bullet-stop lever 12 inside the tube wall, if the depth of the bullet-stop lever 12 is not 11 mm, the measuring device will bulge and leak light, indicating that adjustment is needed.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
