Description
Art
This utility model relates to a kind of sensor for measuring straight-line displacement being applied to aerospace field, is specifically related to the stator assembly of a kind of redundance linear movement pick-up.
Background technology
In field of aerospace, in order to improve the reliability of product, generally require design, install and overlap back-up system, such as more: double remainings, triplex redundance, four remainings.
Generally, redundance linear movement pick-up generally individually includes two primary clusterings: stator assembly, mover assembly；Mover assembly is i.e. the part of the movement of redundance linear movement pick-up, is generally mounted on the part of certain rectilinear movement；Stator assembly is i.e. the fixed part of redundance linear movement pick-up, is generally mounted on certain pedestal, and stator component internal has the parts such as multiple coil blocks, the position at mover assembly place can be changed into the signal of telecommunication and export to external circuit；
Generally, the mover assembly of redundance linear movement pick-up needs loose or that resistance is a less environment, it is simple to mover assembly does straight-line displacement campaign relative to stator assembly, measures position relationship between the two for stator assembly.
Due to machining accuracy and the existence of rigging error, mover assembly and stator assembly have coaxiality error unavoidably, if this bigger error, then mover assembly resistance when mobile can increase, eventually result in the abrasion of mover assembly, bending, hydraulic performance decline, under harsh conditions, mover assembly there will be stuck phenomenon of being failure to actuate, has had a strong impact on reliability and the security of system of redundance linear movement pick-up.
Generally, aerospace field is the highest for the requirement of reliability and security of system, even harsh, therefore, the coaxiality error improving stator assembly and mover assembly as far as possible is necessary.
Generally, the mover assembly of redundance linear movement pick-up can be subdivided into stator assembly coaxiality error reason: the reason of stator assembly, the reason of mover assembly, whole machine installation source of error；This utility model is mainly from the angle analysis of stator assembly and solve problem, and other factors all process with idealization, are not considered.
Generally, the stator assembly of redundance linear movement pick-up includes shell, multiple coil block, rear end cap, how to ensure the appropriate position that multiple coil block is arranged on shell, and guaranteeing that multiple coil block is parallel with the central shaft of shell, these are the key factors of stator assembly coaxiality error.
Generally, the sealing of each part of aerospace field and bonding strength require the highest, parts are required for greatly using welding manner to fix, seal, so the stator assembly of redundance linear movement pick-up is also required to use the mode of welding to fix, prevent inner body because of reasons such as vibrations, cause the loosening of inner body, mobile, come off, finally affect reliability and the safety of complete machine.
Generally, in the production process of redundance linear movement pick-up, need multiple coil blocks are installed in the enclosure, and it is fixed, enter back into the debugging stage, generally, connect have threaded, key and pin to connect with fastening method, interference connection, bonding, rivet, weld；Under normal circumstances, in redundance linear movement pick-up production process, the mode using welding is fixed with shell by multiple coil blocks, then enters back into the debugging stage.
Generally, after metal solder the most non-dismountable, even if after pulling down by force, parts are also scrapped and cannot be continuing with, so finding during follow-up debugging that the stator component output signals of redundance linear movement pick-up is abnormal, the most also having no idea to dismantle, reprocess, the defective work ultimately resulting in product is more.
Summary of the invention
On the one hand, the multiple coil blocks improving redundance linear movement pick-up stator assembly are parallel with the central shaft of shell for this utility model；Thus reduce the coaxiality error of stator assembly and mover assembly, and then improve reliability and the security of system of redundance linear movement pick-up.
Another aspect of the present utility model, multiple coil blocks of redundance linear movement pick-up stator component internal and the fixed form of shell do not use welding, but use key and pin to connect and fix plus threaded mode, treat stator assembly produce, debug complete after, then be welded and fixed；Thus after avoiding Product jointing, debugging cannot the dismantling of substandard product, reprocess, and then improve the qualification rate of product.
This utility model solves its technical problem and be the technical scheme is that and first electrically connected with coil block by cable, the most multiple coil blocks are arranged on the right side of outer casing inner wall, locked spacer is had on the right side of multiple coil blocks, stop pressure ring is had on the right side of locked spacer, having rear end cap on the right side of stop pressure ring, wherein cable is each passed through locked spacer, stop pressure ring, rear end cap.
Its preferred scheme includes: deleted by above-mentioned rear end cap part.
Its another more preferably scheme includes: directly designing a wire hole on the sidewall of shell, after cable and multiple coil block being electrically connected, cable is directly through the wire hole on side wall of outer shell.
The beneficial effects of the utility model are: improve reliability and the security of system of redundance linear movement pick-up, improve the qualification rate of product.
