Description
Technical Field
The invention relates to the technical field of slide rail sleeve processing, in particular to a flexible positioning device and a flexible positioning method for a drain hole of a slide rail sleeve.
Background
The main function of the slide rail sleeve is to provide a motion space for the slide rail in an aircraft wing oil tank, so the slide rail sleeve is usually in a thin-wall, shell-shaped and cantilever beam stressed structure, and the central axis of the slide rail sleeve is consistent with the motion track of the slide rail and is in an arc shape, namely, the arc-shaped axis curved sleeve.
In reality, the structures of the sliding rail sleeves are serialized, however, the external dimensions of the sleeves of each specification are limited by the installation positions of the sleeves, and a certain difference is presented. One typical configuration of the sliding track sleeve is shown in fig. 1, the diameter of the sleeve is generally between 100mm and 300mm, the wall thickness of the part is between 2mm and 6mm, the central axis of the sleeve is in a spatial arc shape, the radius of the arc axis is between 500mm and 2000mm, and the length of the sleeve is between 400mm and 700 mm. The diameter, the radius of the arc axis and the length of the sleeve of each specification are slightly different, so that the universality of the series of sleeves is poor.
Wherein, as shown in figure 2, the middle of the drain nozzle of the slide rail sleeve is provided with a through hole for timely draining condensed water generated in the flying process out of the inner cavity of the sleeve. Therefore, the axis of the drain hole on the cylinder body is positioned at the lowest point of the installation position of the sleeve, and the drain hole is deviated from the middle layer surface of the cylinder body by a certain distance delta x, and the delta x is generally between 0mm and 5 mm.
Aiming at the sliding rail sleeve structure, the best method for realizing the integrated manufacture is to adopt a welding method for sectional splicing at present, namely, a drain hole is formed at the corner of the tail part of the cylinder by taking the lowest point of the sleeve as the center, then a drain pipe joint is welded at the drain hole, and finally the connection of a flange plate and the cylinder is realized.
At present, a special hole-making positioning tool shown in figure 3 is adopted for positioning a drain hole at a corner of the tail part of a cylinder, the cylinder is generally placed in a cylinder-shaped face seat firstly, an opening baffle of the cylinder is finely adjusted to be in contact with an opening plane of the cylinder, a locking clamp ring is installed to fix the cylinder in the cylinder-shaped face seat, a positioning hole-making rod on an upright post is rotated to insert a positioning pin, a drill bushing is inserted into a hole at the tail end of the upright post, and a downward hole is made by taking the drill bushing as the drill bushing. The hole position is guaranteed by the precision of a special hole-making positioning tool, and can be guaranteed to be located in the range of +/-3 mm of the lowest point of the sleeve installation position.
The existing hole-making positioning tools correspond to one set of special hole-making positioning tool for each specification sleeve, and the different hole-making positioning tools lack universality and assembly flexibility. And as shown in figure 3, the barrel face seat and the locking clamp ring are in clearance fit, when the barrel is placed in the barrel face seat, the barrel needs to be axially rotated for fine adjustment, otherwise the barrel is easily interfered with when the locking clamp ring is installed. Meanwhile, after the assembly is completed at the assembly station by adopting the hole-making positioning tool, the hole-making positioning tool is transferred to the hole-making station for positioning and preparing the drain hole, and then the hole-making positioning tool is transferred to the assembly station for disassembling the barrel body after the hole-making, so that the efficiency is low. In addition, the hole-making location frock of multiple specification occupies that factory building area is great, and the cost is higher, and later stage need invest more manpower and go to maintain and maintain.
In view of the above disadvantages, how to provide a flexible positioning device and a positioning method for a drain hole of a sliding rail sleeve, which meet the positioning requirement for realizing drain holes of sliding rail sleeves of various specifications on one set of positioning device, significantly save the manufacturing cost, and improve the positioning and hole-making processing efficiency of the drain hole is a technical problem to be solved by technical personnel in the field.
