Problems solved by technology

However, the number of locators that need to be determined for each clamping is too large, and the efficiency is low
And for slender, titanium alloy aircraft catheters with different pipe diameters, the above-mentioned array positioning device can not play its advantages, and the positioning of the array form will cause a kind of waste when used on slender pipe parts, which is inefficient and can reach Less than good positioning effect
Since this positioning device is used for the welding of aircraft conduits, the positioning effect required by welding cannot be well achieved through the traditional array positioning method, and the positioning scheme needs to be optimized

Embodiment Construction

[0019] refer to figure 1 Schematic diagram of the overall structure. The base is used as the foundation, the clamping ring A (21) and the clamping ring B (28) are installed on the base as fixed ends, the clamping ring C (26) cooperates with the mobile platform through the positioning hole (35) of the mobile platform, and the mobile platform passes through The slide block positioning hole (36) is matched with the slide block (20), and the slide block (20) is matched with the guide rails (16, 19), so as to be able to slide freely thereon. Thus, through the rotation of the lead screw (17), the mobile platform (27) can be controlled to move freely on the guide rails (16, 19), and the distance between the clamping ring B (28) and the clamping ring C (26) can be changed. relative distance. Two connecting rods (24) and a clamping plate (25) form a linkage mechanism, and the distance between the clamping plate (25) and the polished rod (23) is changed according to the relative dista...

Abstract

The invention discloses a flexible positioning device for a slender guide pipe welding structure. The flexible positioning device comprises a coupler, a base, a locking nut, a sliding block pushing nut, a clamping ring, a clamping ring support, a ball screw, a polished rod, a rotating handle, a clamping plate, an inner hexagon screw, an outer hexagon screw, an elastic check ring, a guide rail, a movable platform, a sliding block, a positioning pin and the like. The invention provides a flexible positioning clamp for welding a slender guide pipe structure, which can realize flexible clamping ofa guide pipe with the outer diameter of 20mm to 100mm and has higher positioning precision. Besides, according to the flexible positioning device, an innovative structure is utilized, the limitationthat a sleeve type positioning device needs to be axially inserted and clamped is broken through, and the efficiency of the clamping process is improved by adopting the mode of radial placing and pre-clamping.

Description

technical field [0001] The invention belongs to the technical field of structural design and application of a flexible positioning device, and relates to a flexible positioning device capable of clamping elongated catheters with different axial diameters. Background technique [0002] There are a large number of conduit structures with complex structures and various shapes in the hydraulic system, fuel system and environmental control system of the aircraft, which are used to transport the medium between the systems. In various catheter manufacturing processes such as cutting, welding and assembly, a positioning device for positioning and clamping the catheter is required to ensure the precise shape, size and positional relationship in the process of the catheter. At present, there are mainly two kinds of catheter positioning devices, the special positioning device and the combined positioning device, both at home and abroad. The special positioning device is a fixed positi...
