Description

Technical Field

[0001] The utility model relates to a tool, in particular to a tool for measuring the height between an upper stopper and a guide rail. Background Art

[0002] During routine repairs on a certain type of ship's upper stop, measuring the stopper is extremely difficult due to the limited space. Repair personnel typically reach into the launch tube and manually use a ruler to measure both the raised and lowered positions. However, this method is inefficient and can easily lead to significant errors in equipment measurement. The upper stopper's function is to lock the guide of the launchable element with front and rear stops, securing the element axially within the launch tube and preventing it from moving forward or backward when the ship pitches. During launch, the front and rear stops automatically lift, releasing the element from obstruction. Any measurement errors can directly impact the launch of the element, and the complex environment makes calibration difficult for technicians. Summary of the Invention

[0010] like Figures 1 to 3 As shown, the tooling for measuring the height between the upper stopper and the guide rail of the present invention comprises a base 2, the lower surface of which is formed into a curved surface 18. The lower end of a vertical shaft 3 is fixedly connected to the base 2 via a cylindrical pin 1. A fixing sleeve 11 is fixed to the vertical shaft 3, to which a slide rail 10 is fixed. A sliding plate 12 is mounted on the slide rail 10, and the sliding plate 12 slides perpendicularly to the longitudinal direction of the vertical shaft 3. The sliding plate 12 is fixedly connected to the scale seat 4 of a vernier caliper, whose scale bar 15 is parallel to the longitudinal direction of the vertical shaft 3. A spring 6 is positioned within the upper end of the vertical shaft 3. The lower end of the spring 6 rests on a step on the vertical shaft 3, while the upper end of the spring 6 rests on the lower end surface of a piston 8. The lower portion of the piston 8 is positioned within the inner cavity of the vertical shaft 3. A ring 7 is threadedly connected to the upper end of the vertical shaft 3. The upper portion of the piston 8 extends through the center hole of the ring 7 and is threadedly connected to the top cover 9. The ring 7 limits the axial position of the piston 8.

[0011] The fixing sleeve 11 is fixedly connected to the slide rail 10 by connecting screws 17 and pins 13; the fixing sleeve 11 is fixedly connected to the vertical shaft 3 by fixing screws 5; there is a T-slot on the slide rail 10, and the sliding plate 12 coincides with the T-slot. The sliding plate 12 is threaded with a positioning screw 14, and by tightening the positioning screw 14, the sliding plate 12 and the slide rail 10 can be relatively fixed.

[0012] During use, the device is installed between the upper and lower rails of a ship. The curved surface 18 below the base 2 aligns with the curved surface on the lower rail, and the upper cover 9 rests against the upper rail. The spring 6 is compressed, the positioning screw 14 is loosened, and the sliding plate 12 is moved laterally to adjust the vernier caliper blade 15 to the appropriate horizontal position. The blade 15 can be adjusted vertically using the jackscrew 16.
