Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039]The invention can be used to measure the ring head screw mechanism in the unlocking mechanism in the form of connecting rods used in the core stage and booster of the aerospace vehicle. The unlocking mechanism is composed of a barrel section, a ring head screw mechanism, an explosive bolt and the like. Because the inner side of the ring head screw is embedded with joint bearings and has a high degree of freedom of movement, the invention proposes a solution that traditional calipers cannot achieve measurement; at the same time, it solves the problem that the quality of the unlocking mechanism is relatively large, and manual adjustment requires the cooperation of multiple people, which is time-consuming and labor-intensive. The problem of extremely low efficiency; at the same time, the unlocking mechanism needs to be installed at ...

Abstract

The invention discloses a device and method capable of accurately adjusting and measuring the length of a ring head screw telescopic rod. The device comprises a base (11), a handle (16), a linear sliding rail (14), a first sliding table, a second sliding table, a limiting mechanism (15), a first threaded supporting column (12), a locking nut (13) and a driving mechanism of the second sliding table. A boss is arranged at one end of the base (11), and the first threaded supporting column (12) is installed on the boss at one end of the base (11). The first sliding table is used for locking another end of a tested ring head screw telescopic rod. The second sliding table is arranged between the boss at one end of the base (11) and the first sliding table. The second sliding table is matched with a middle part of the tested ring head screw telescopic rod and can drive the tested ring head screw telescopic rod to rotate. The driving mechanism of the second sliding table is arranged on the base (11) and is connected with the second sliding table, so that the second sliding table moves along the linear sliding rail (14), and the problems of length measurement and adjustment are solved.

Description

technical field [0001] The invention relates to a device and method capable of accurately adjusting and measuring the length of a ring head screw telescopic rod, belonging to the technical field of product length measurement and adjustment. Background technique [0002] With the development of aerospace technology, the pace of development of various models has been accelerated, and the connection forms between structures are intricate, which puts forward higher precision requirements for product installation. For a certain type of core stage and booster connection unlocking mechanism, its form is a telescopic rod with circular ring head screws at both ends. It has problems such as length adjustment difficulties, low precision, and low efficiency. It lacks a precise adjustment and measurement method. . At present, there are different length measurement tools in the market, each has its advantages and disadvantages. The biggest disadvantage is that when using this type of too...
